Change in oral function was evaluated longitudinally in elderly persons participating in an Exercises for Healthy Oral Function program implemented as part of the Long-Term Care Prevention Project. The participants comprised high-risk and healthy persons aged 65 yr or over. A questionnaire was used to classify them into two groups ('every day or sometimes' or 'rarely') at the end of the study for a comparison of change in repetitive saliva swallowing test (RSST) scores and oral diadochokinesis between 3 time points: at before, at immediately after, and at 1 yr after completion of the program. The average RSST score showed a decrease at 1 yr after intervention, but the difference was not statistically significant. Oral diadochokinesis showed a significant increase for all syllables upon completion of the program compared with at the beginning. This was followed by a significant decrease at 1 yr later compared with at the time of completion in the 'rarely' group for all syllables, but not in the 'every day or sometimes' group. In addition, the number of repetitions was significantly lower in the 'rarely' group than in the 'every day or sometimes' group for all syllables at 1 yr after completion. The results of the present study suggest that Long-Term Care Prevention Projects are necessary to maintain and improve oral function.

Epidural anaesthesia and analgesia - effects on surgical stress responses and implications for postoperative nutrition.

PubMed

Holte, K; Kehlet, H

2002-06-01

Surgical injury leads to an endocrine-metabolic and inflammatory response with protein catabolism, increased cardiovascular demands, impaired pulmonary function and paralytic ileus, the most important release mechanisms being afferent neural stimuli and inflammatory mediators. Epidural local anaesthetic blockade of afferent stimuli reduces endocrine metabolic responses, and improve postoperative catabolism. Furthermore, dynamic pain relief is achieved with improved pulmonary function and a pronounced reduction of postoperative ileus, thereby providing optimal conditions for improved mobilization and oral nutrition, and preservation of body composition and muscle function. Studies integrating continuous epidural local anaesthetics with enforced early nutrition and mobilization uniformly suggest an improved recovery, decreased hospital stay and convalescence. Epidural local anaesthetics should be included in a multi-modal rehabilitation programme after major surgical procedures in order to facilitate oral nutrition, improve recovery and reduce morbidity.

Long-term improvements in oral communication skills and quality of peer relations in children with cochlear implants: parental testimony.

2014-11-01

Few research studies have examined longitudinal improvements in oral communication skills and quality of peer relationships of children with implants. Moreover, although the emerging literature suggests that improvement in social functioning follows improvement in oral communication, it is still unknown what factors enhance or impede the relations between these constructs. Based on parent interviews, the current study examined the long-term improvements in speech and oral language skills and relationships with hearing peers in 19 implanted children. Results demonstrate that on average, children continue to improve in oral communication skills and quality of peer relationships even years after implantation, especially those with initial poorer skills. While oral communication ability and quality of peer relationships are strongly associated at each time point, gains in these two variables are associated only for some of the children. Other factors, including self-confidence and peer acceptance, seem to moderate this relationship. Qualitative data are presented to illustrate these relations among variables and to assist in theory building. The results highlight the need for more specific examination of various developmental periods in combination with the progress of oral communication and peer relationships among children with implants. © 2013 John Wiley & Sons Ltd.

This study examined the caregivers' perception of the effect of dental conditions on general well-being and family life of a group of human immunodeficiency virus (HIV)-infected Nigerian children. A secondary aim was to investigate correlations between the children's sociodemographic and health-related variables and caregivers' global ratings of oral health and well-being. Study Design A cross-sectional questionnaire-based survey was conducted among parents/caregivers of 95 HIV-positive children receiving care at the Lagos State University Teaching Hospital, Nigeria. The "Parental-Caregivers Perception Questionnaire" which included measures of global ratings of oral health and well-being as well as effects of oral health on domains of oral symptoms, functional limitations, emotional well-being, and family well-being/parental distress was used. Assessment was based on the child's oral health within the preceding 3 months of the study. The most affected subscale of the oral health-related quality of life was functional limitation followed by parental distress and then oral symptoms. Caregivers of older children were 2½ times more likely to view oral health as impacting their child's overall health (P = 0.034). Furthermore, caregivers of children who had not yet commenced antiretroviral therapy were 15% more likely to report oral symptoms (P = 0.024) and 11% were more likely to be distressed. Data entry, validation, and analysis were done using SPSS version 17.0. Findings were considered to be statistically significant when 95% confidence intervals were not overlapping. According to caregivers' perceptions, oral symptoms, functional limitations, and parental distress outweighed emotional well-being in impacting a child's oral health quality of life. Oral health programs to improve the knowledge of caregivers on the importance of oral health in HIV-positive children are necessary for improvement in overall quality of life.

The effect of isoflavone on endothelial function in postmenopausal women is controversial. The objective of this study was to evaluate the effect of oral isoflavone supplementation on endothelial function, as measured by flow-mediated dilation (FMD), in postmenopausal women. A meta-analysis of randomized placebo-controlled trials was conducted to evaluate the effect of oral isoflavone supplementation on endothelial function in postmenopausal women. Trials were searched in PubMed, Embase, the Cochrane Library database, and reviews and reference lists of relevant articles. Summary estimates of weighted mean differences (WMDs) and 95% CIs were obtained by using random-effects models. Meta-regression and subgroup analyses were performed to identify the source of heterogeneity. A total of 9 trials were reviewed in the present meta-analysis. Overall, the results of the 9 trials showed that isoflavone significantly increased FMD (WMD: 1.75%; 95% CI: 0.83%, 2.67%; P = 0.0002). Meta-regression analysis indicated that the age-adjusted baseline FMD was inversely related to effect size. Subgroup analysis showed that oral supplementation of isoflavone had no influence on FMD if the age-adjusted baseline FMD was > or = 5.2% (4 trials; WMD: 0.24%; 95% CI: -0.94%, 1.42%; P = 0.69). This improvement seemed to be significant when the age-adjusted baseline FMD levels were <5.2% (5 trials; WMD: 2.22%; 95% CI: 1.15%, 3.30%; P < 0.0001), although significant heterogeneity was still detected in this low-baseline-FMD subgroup. Oral isoflavone supplementation does not improve endothelial function in postmenopausal women with high baseline FMD levels but leads to significant improvement in women with low baseline FMD levels.

The purpose of this work was to improve the oral bioavailability of a poorly soluble functional food ingredient, the total flavones of Hippophaë rhamnoides L. (TFH). A self-microemulsion drug delivery system (SMEDDS) was developed to overcome the problems of poor absorption of TFH in vivo. The optimal SMEDDS significantly enhanced the solubility of TFH up to 530 times compared to that in water. The mean droplet size was 61.76 nm with uniform distribution. And the loaded system was stable at 25 °C for 3 mo with transparent appearance. The in vitro release of TFH from SMEDDS was faster and more complete than that from suspension. After oral administration of TFH-SMEDDS in rats, the relative bioavailability of TFH was dramatically improved for 3.09 times compared with the unencapsulated form. The investigation indicated the potential application of SMEDDS as a vehicle to improve the oral bioavailability of TFH. The lipid-based nanotechnology, namely self-microemulsion drug delivery system (SMEDDS) was used to improve the bioavailability and oral delivery of total flavones of Hippophaë rhamnoides L. (TFH). The relevant bioavailability of TFH could be remarkably 3-fold improved by the optimized SMEDDS. The SMEDDS produced via a simple one-step process for poorly soluble TFH to achieve a significant improvement in the bioavailability, may endorse the promising utilization of TFH in functional foods as well as pharmaceutical fields with an enhanced absorption in vivo. © 2017 Institute of Food Technologists®.

Cancer of the oral cavity.

Montero, Pablo H; Patel, Snehal G

2015-07-01

Cancer of the oral cavity is one of the most common malignancies worldwide. Although early diagnosis is relatively easy, presentation with advanced disease is not uncommon. The standard of care is primary surgical resection with or without postoperative adjuvant therapy. Improvements in surgical techniques combined with the routine use of postoperative radiation or chemoradiation therapy have resulted in improved survival. Successful treatment is predicated on multidisciplinary treatment strategies to maximize oncologic control and minimize impact of therapy on form and function. Prevention of oral cancer requires better education about lifestyle-related risk factors, and improved awareness and tools for early diagnosis. Copyright © 2015 Elsevier Inc. All rights reserved.

This report describes the clinical orthodontic management of a patient with spastic quadriplegia and cerebral palsy. Guidelines to overcome difficulties encountered during the treatment period are suggested. A 13-year-old boy with cerebral palsy and spastic quadriplegia complained of an undesirable oral appearance because of his malocclusion. He had a Class II molar relationship, with severe maxillary and moderate mandibular anterior crowding. Enamel hypoplasia was apparent on all teeth. He had losses of body function and upper extremity function of 70% and 39%, respectively. His physical limitations necessitated a treatment approach that did not rely on patient-dependent appliances. The treatment plan called for maxillary first premolar extractions, mandibular incisor protrusion, and air rotor stripping. The patient's oral function and esthetic appearance were significantly improved. Aligned dental arches with good occlusion were obtained. The patient's self-confidence improved during the treatment period. Physical appearance can influence personality and social acceptability. Corrective orthodontic treatment for patients with physical handicaps can improve not only oral function, but also self-confidence and self-esteem.

Improving the oral bioavailability of curcumin using novel organogel-based nanoemulsions.

PubMed

Yu, Hailong; Huang, Qingrong

2012-05-30

Curcumin is a natural bioactive compound with many health-promoting benefits. Its low oral bioavailability limits its application in functional foods. In the present study, novel organogel-based nanoemulsions have been developed for oral delivery of curcumin and improvement of its bioavailability. Recently developed curcumin organogel was used as the oil phase in the curcumin nanoemulsion formulation. Tween 20 was selected as the emulsifier on the basis of maximum in vitro bioaccessibility of curcumin in the nanoemulsion. In vitro lipolysis profile revealed that the digestion of nanoemulsion was significantly faster and more complete than the organogel. Permeation experiments on Caco-2 cell monolayers suggested that digestion-diffusion was the major absorption mechanism for curcumin in the nanoemulsion. Furthermore, in vivo pharmacokinetics analysis on mice confirmed that the oral bioavailability of curcumin in the nanoemulsion was increased by 9-fold compared with unformulated curcumin. This novel formulation approach may also be used for oral delivery of other poorly soluble nutraceuticals with high loading capacity, which has significant impact in functional foods, dietary supplements and pharmaceutical industries.

The development of drug nanoparticles has attracted substantial attention because of their potential to improve the dissolution rate and oral availability of poorly water-soluble drugs. This review summarizes the recent articles that discussed nanoparticle-based oral drug delivery systems. The preparation methods were categorized as top-down and bottom-up methods, which are common methods for preparing drug nanoparticles. In addition, methods of handling drug nanoparticles (e.g., one-step preparation of nanocomposites which are microparticles containing drug nanoparticles) were introduced for the effective preservation of drug nanoparticles. The carrier-based preparation of drug nanoparticles was also introduced as a potentially promising oral drug delivery system.

To examine the strength of associations between child oral health and aspects of the home environment (child behaviour, parental psychological distress and family functioning) in a large sample of 1- to 12-year-old Australian children. The current study used data from the 2006 Victorian Child Health and Wellbeing Study. Data were obtained on 4590 primary carers. Measures of the family environment included the level of family functioning, parental psychological distress, child's emotion and behavioural problems and the family structure. The odds of children having good oral health status were lower with increasing parental psychological distress and poor family functioning across all age groups, and lower with increasing child mental health or conduct problems among children aged 4 years or older. Socioeconomic factors were also related to child oral health status, but this was significant only among children aged 4-7 years, with the odds of children having good oral health status 68% higher in households with a yearly income ≥AUD$ 60 000 compared with households with income <$20 000 (P < 0.05). In order to address inequities in the experience of poor oral health, solutions that encompass social, economic and psychosocial dimensions will be required. Integrating intervention strategies that promote oral, healthy family functioning and the mental health of parents and children into existing systems reaching vulnerable community members may improve child oral health outcomes and reduce the unequal distribution of oral disease across the social gradient. © 2013 John Wiley & Sons Ltd.

In order to develop orally active pure antiestrogens, we incorporated the carboxy-containing side chains into the 7alpha-position of the steroid scaffold and found that 17-keto derivative CH4893237 (12b) functioned as a pure antiestrogen with its oral activity much superior to clinically used pure antiestrogen, ICI182,780. Results from the pharmacokinetic evaluation indicated that the potent antiestrogen activity at oral dosing in mice attributed to both improved absorption from the intestinal wall and metabolic stability in liver.

Recent research suggests that there is a correlation between nutrition, oral health, dietary habits, patients' satisfaction and their socio-economic status. However, the dependent and independent variables have remained unclear. This exploratory interventional study aimed to identify the impact of denture improvement on the nutritional status as well as the oral health-related quality of life in geriatric patients. Forty-seven patients who were capable of feeding themselves (minimum age: 60 years) and with dentures requiring repair or replacement were selected from a random sample of 100 residents of two nursing homes. Before and 6 months after the dentures were optimised a Mini Nutritional Assessment (MNA) and a masticatory function test were carried out. Nutritional markers (pre-albumin, serum albumin, zinc) were determined and an OHIP-G14 (Oral Health Impact Profile, German version) was recorded in order to determine the effect of the optimised oral situation on the patient's nutritional status and oral health-related quality of life. Despite the highly significant improvement in masticatory ability after the optimisation of the dentures, no general improvement regarding the nutritional status was observed since the albumin, zinc and MNA values remained unchanged and pre-albumin even decreased. Since masticatory ability and masticatory efficiency are not the only factors affecting this, prosthetic measures alone apparently cannot effect a lasting improvement in nutritional status as masticatory ability and masticatory efficiency are not the only factors of influence. Nutrition is not only a matter of masticatory function, but also depends on other influencing factors (e.g. habits, taste and cultural customs as well as financial and organisational aspects).

Tongue function can affect both the oral and pharyngeal stages of the swallowing process, and proper tongue strength is vital for safe oropharyngeal swallowing. This trial investigated the effect of tongue-to-palate resistance training (TPRT) on tongue strength and oropharyngeal swallowing function in stroke with dysphagia patients. This trial was performed using a 4-week, two-group, pre-post-design. Participants were allocated to the experimental group (n = 18) or the control group (n = 17). The experimental group performed TPRT for 4 weeks (5 days per week) and traditional dysphagia therapy, whereas the control group performed traditional dysphagia therapy on the same schedule. Tongue strength was measured using the Iowa Oral Performance Instrument. Swallowing function was measured using the videofluoroscopic dysphagia scale (VDS) and penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study. Experimental group showed more improved in the tongue strength (both anterior and posterior regions, P = 0·009, 0·015). In addition, the experimental group showed more improved scores on the oral and pharyngeal phase of VDS (P = 0·029, 0·007), but not on the PAS (P = 0·471), compared with the control group. This study demonstrated the effectiveness of TPRT in increasing tongue muscle strength and improving swallowing function in patients with post-stroke dysphagia. Therefore, we recommend TPRT as an easy and simple rehabilitation strategy for improving swallowing in patients with dysphagia. © 2016 John Wiley & Sons Ltd.

Glutamate (GLU) and gamma-amino butyric acid (GABA) are essential amino acids (AA) for brain function serving as excitatory and inhibitory neurotransmitter respectively. Their tablets are available in market for improving gut function and muscle performance. Despite of having a major role during memory formation and processing, effects of these tablets on brain functioning like learning and memory have not been investigated. Therefore, present study is aimed to investigate the effects of orally supplemented GLU and GABA on learning and memory performance and further to monitor related effects of these orally supplemented GLU and GABA on brain levels of these AA. Three groups of rats were supplemented orally with drinking water (control group) or suspension of tablets of GABA and Glutamate, respectively for four weeks. Cognitive performance was determined using behavioral tests (Novel object recognition test, Morris water maze, Passive avoidance test) measuring recognition, spatial reference and aversive memory. Levels of GLU, GABA and acetylcholine (ACh) were estimated in rat hippocampus. Results showed that chronic oral administration of GLU and GABA tablets has a significant impact on brain function and can alter GLU and GABA content in rat hippocampus. Compared to GABA, GLU supplementation specifically enhances memory performance via increasing ACh. Thus, GLU can be suggested as a useful supplement for improving learning and memory performance and neurochemical status of brain and in future could be effective in the treatment of neurological disorders affecting learning and memory performance.

OBJECTIVE To investigate the effect of biliopancreatic diversion (BPD) surgery on β-cell function in grade I and II obese patients with type 2 diabetes using oral and intravenous glucose loads. RESEARCH DESIGN AND METHODS Sixty-eight women were divided into the following three groups: 19 lean-control (23.0 ± 2.2 kg/m2) and 18 obese-control (35.0 ± 4.8 kg/m2) subjects with normal glucose tolerance, and 31 obese patients with type 2 diabetes (36.3 ± 3.7 kg/m2). Of the 31 diabetic women, 64% underwent BPD (n = 20, BMI: 36.5 ± 3.7 kg/m2) and were reassessed 1 month after surgery. Oral glucose tolerance tests and hyperglycemic clamps were performed. Mathematical modeling was used to analyze basal and stimulated β-cell function, insulin sensitivity (IS), hepatic extraction (HE) of insulin, and delay time of β-cell response to a specific plasma glucose concentration. RESULTS After BPD, restoration of the basal disposition index (P < 0.001) and improvement of the stimulated disposition indices in oral and intravenous glucose stimulation of the β-cell were observed (P < 0.05). In both dynamic tests, there were no changes in the delay time of β-cell response. IS for oral glucose stimulation (ISoral) and intravenous clamp glucose stimulation (ISclamp) was completely normalized (P < 0.001). ISoral and ISclamp increased approximately 5.0-fold and 3.5-fold, respectively (P < 0.01). The HE of insulin increased in the basal (P < 0.05) and stimulated states (P < 0.01). CONCLUSIONS β-Cell function, IS, and HE of insulin improved after BPD, which improved glycemic control. PMID:24135388

Oral mucositis is a common side effect of systemic chemotherapy and radiotherapy of head and neck in patients with cancer. Severe oral mucositis is painful and affects oral functions, including intake of food and medications and speech. Prevention of oral mucositis affects the life quality of patients. Recent studies have been focused on natural products to improve or reduce this complication. Many clinical trials have been performed to assess natural products for treatment of mucositis and their results are promising. The authors reviewed the evidence for natural products in the prevention and treatment of oral mucositis induced by radiation therapy and chemotherapy. PMID:26306626

Pemphigus vulgaris is a rare cause of oral mucosal ulceration. A 47-year-old Chinese man presented with a 3-month history of oral ulceration. There were no lesions on the skin or other mucosal sites. Histology and immunostaining were consistent with pemphigus vulgaris. Systemic and topical corticosteroids were instituted, together with topical antifungals. Conventional periodontal therapy was carried out to improve gingival/oral health. Control of oral ulceration was achieved with re-establishment of normal oral function. No other sites to date have been involved. Chronic oral ulceration can be the sole manifestation of pemphigus vulgaris, at least initially. Early recognition of this lesion may prevent delayed diagnosis and inappropriate treatment of a potentially chronic dermatological condition.

Indigenous Australians suffer substantially poorer oral health than their non-Indigenous counterparts and new approaches are needed to address these disparities. Previous work in Port Augusta, South Australia, a regional town with a large Indigenous community, revealed associations between low oral health literacy scores and self-reported oral health outcomes. This study aims to determine if implementation of a functional, context-specific oral health literacy intervention improves oral health literacy-related outcomes measured by use of dental services, and assessment of oral health knowledge, oral health self-care and oral health- related self-efficacy. This is a randomised controlled trial (RCT) that utilises a delayed intervention design. Participants are Indigenous adults, aged 18 years and older, who plan to reside in Port Augusta or a nearby community for the next two years. The intervention group will receive the intervention from the outset of the study while the control group will be offered the intervention 12 months following their enrollment in the study. The intervention consists of a series of five culturally sensitive, oral health education workshops delivered over a 12 month period by Indigenous project officers. Workshops consist of presentations, hands-on activities, interactive displays, group discussions and role plays. The themes addressed in the workshops are underpinned by oral health literacy concepts, and incorporate oral health-related self-efficacy, oral health-related fatalism, oral health knowledge, access to dental care and rights and entitlements as a patient. Data will be collected through a self-report questionnaire at baseline, at 12 months and at 24 months. The primary outcome measure is oral health literacy. Secondary outcome measures include oral health knowledge, oral health self-care, use of dental services, oral health-related self-efficacy and oral health-related fatalism. This study uses a functional, context-specific oral health literacy intervention to improve oral health literacy-related outcomes amongst rural-dwelling Indigenous adults. Outcomes of this study will have implications for policy and planning by providing evidence for the effectiveness of such interventions as well as provide a model for working with Indigenous communities.

To investigate the efficacy and urodynamic effects of baclofen in women with functional bladder outlet obstruction. Between January 2011 and December 2012, women who underwent baclofen treatment for functional bladder outlet obstruction, defined as <15 mL/s maximum flow rate and >20 cmH2 O detrusor pressure at maximum flow rate, but without significant anatomic causes, were retrospectively reviewed. Urodynamic variables at baseline and after 12 weeks of treatment were compared. Twenty women with functional bladder outlet obstruction underwent 12 weeks of baclofen treatment (oral baclofen 5 mg, three times daily). All patients reported improvement in voiding dysfunction symptoms after treatment, and no significant adverse effects were found on review of medical records. All patients underwent urodynamic studies after 12 weeks' treatment. Voided volume, voiding efficiency and maximum flow rate at voiding cystometry were significantly improved (mean, 273 vs. 368 mL, P = 0.002; 62.8% vs. 73.6%, P <0.001, and 10.3 vs. 11.6 mL/s, P = 0.046; respectively). Moreover, baclofen did not affect continence function, as indicated by non-significant changes in the parameters of urethral pressure profiles. Oral baclofen can improve symptoms of voiding dysfunction, voided volume, voiding efficiency and maximum flow rate in women with functional bladder outlet obstruction. None of the patients experienced intolerable side-effects. Thus, oral baclofen may be used as an initial treatment for women with symptoms of voiding dysfunction. © 2016 Japan Society of Obstetrics and Gynecology.

A group of 20 chronic bronchopneumopathics was treated for 15 days with fenspiride orally and i.m. The behaviour of a set of functional respiratory and haemogasanalytic parameters was monitored at various times (basic, 5th, 10th and 15th days). Progressive, significant improvements in VC, FEV1, RV and in related parameters were observed. These were attributed to the drug's anti-inflammatory effect in the respiratory ways as well as to its direct antibronchospastic action. Stress is laid on the excellent clinical tolerance of fenspiride following its oral and i.m. administration.

Thiolated chitosans: useful excipients for oral drug delivery.

PubMed

Werle, Martin; Bernkop-Schnürch, Andreas

2008-03-01

To improve the bioavailability of orally administered drugs, formulations based on polymers are of great interest for pharmaceutical technologists. Thiolated chitosans are multifunctional polymers that exhibit improved mucoadhesive, cohesive and permeation-enhancing as well as efflux-pump-inhibitory properties. They can be synthesized by derivatization of the primary amino groups of chitosan with coupling reagents bearing thiol functions. Various data gained in-vitro as well as in-vivo studies clearly demonstrate the potential of thiolated chitosans for oral drug delivery. Within the current review, the synthesis and characterization of thiolated chitosans so far developed is summarized. Features of thiolated chitosans important for oral drug delivery are discussed as well. Moreover, different formulation approaches, such as matrix tablets and micro-/nanoparticles, as well as the applicability of thiolated chitosans for the oral delivery of various substance classes including peptides and efflux pump substrates, are highlighted.

2004-01-01

This case study examined the effectiveness of a programme designed to improve anticipatory postural control in an adolescent over years 2 and 3 post-traumatic brain injury (TBI). It was hypothesized that her difficulty in walking and talking simultaneously was caused by excessive co-activation of extremity, trunk, and oral musculature during upright activities. The participant was treated weekly by physical and speech therapy. Treatment focussed on improving anticipatory postural control during gross motor activities in conjunction with oral-motor function. Initially, the participant walked using a walker at a speed of 23 cm s(-1). Two years later, she could walk without a device at 53 cm s(-1). Initial laryngoscopic examination showed minimal movement of the velum or pharyngeal walls; full movement was present after treatment. The measure of intelligibility improved from no single word intelligible utterances to 85% intelligible utterances after 2 years. The results suggest that less compensatory rigidification of oral musculature was needed to maintain an upright position against gravity as postural control improved. An adolescent 1-year post-TBI was followed as she underwent additional rehabilitation focussed on improving anticipatory postural control. The functional goal of simultaneously talking while walking was achieved through this intervention.

To systematically review the effectiveness of oral baclofen versus placebo or other antispastic oral medications in terms of body function, level of activity, and quality of life in children and adolescents with spastic cerebral palsy who are younger than 18 years. Cochrane Library, Health Science Databases, DARE, LILACS, Embase, MEDLINE, OTseeker, PEDro, PsycINFO, SpeechBITE, ScienceDirect, Scopus, Trip, ClinicalTrials.gov, Google Scholar, OpenGrey, and manual search. Randomized or not randomized controlled trials and cohort studies comparing the effect of any dosage of oral baclofen with that of no treatment, placebo, or another antispastic medication in children and adolescents with spastic cerebral palsy were selected. Following the Cochrane Handbook for Systematic Reviews of Interventions guidelines, 2 reviewers independently searched articles in databases from their inceptions until October 2014. Six randomized controlled trials involving a total of 130 patients were selected. Studies show a great variability in motor classification, dosage of baclofen, and outcome measures. There is conflicting evidence on the effectiveness of oral baclofen in reducing muscle tone or improving motor function or the level of activity. The overall methodological quality of the studies was low. The main qualitative limitations of the studies correspond to serious risk of bias, inconsistency of results, unpowered sample size, and publication bias. There are insufficient data to support or refute the use of oral baclofen for reducing spasticity or improving motor function in children and adolescents with spastic cerebral palsy.

Erlotinib and Rapamycin are both in clinical use and experimental inhibition of their respective molecular targets, EGFR and mTORC1, has improved recovery from spinal cord injury. Our aim was to determine if daily Erlotinib or Rapamycin treatment started directly after spinal contusion injury in rats improves locomotion function or recovery of bladder function. Stockholm, Sweden. Rats were subjected to contusion injuries and treated during the acute phase with either Erlotinib or Rapamycin. Recovery of bladder function was monitored by measuring residual urine volume and hindlimb locomotion assessed by open-field observations using the BBB rating scale as well as by automated registration of gait parameters. Body weights were monitored. To determine whether Erlotinib and Rapamycin inhibit the same signaling pathway, a cell culture system and western blots were used. Erlotinib accelerated locomotor recovery and slightly improved bladder recovery; however, we found no long-term improvements of locomotor function. Rapamycin did neither improved locomotor function nor bladder recovery. In vitro studies confirmed that Erlotinib and Rapamycin both inhibit the EGFR-mTORC1 signaling pathway. We conclude that none of these two drug regimes improved long-term functional outcome in our current model of spinal cord injury. Nevertheless, oral treatment with Erlotinib may offer modest temporary advantages, whereas treatment with Rapamycin does not.

The objective of this study was to assess the effects of a hyperproteic, hypercaloric oral nutritional supplement with prebiotic fiber, vitamin D, and calcium, plus a standardized physical intervention, in the functional status, strength, nutritional status, and quality of life of frail institutionalized older adults. Multicentric prospective observational study under usual clinical practice conditions. Four nursing homes from Burgos (2), Albacete, and Madrid, Spain. Participants included 91 institutionalized older adults (age ≥70), able to walk 50 m, and meeting at least 3 of the Fried frailty phenotype criteria. Daily intake of two 200-mL bottles of an oral nutritional supplement, each bottle containing 300 kcal, 20 g protein, 3 g fiber, 500 IU vitamin D, and 480 mg calcium, plus a standardized physical exercise training consisting of flexibility, balance, and strengthening exercises for arms and legs, 5 days per week. Short Physical Performance Battery (SPPB), Short-Form-Late-Life Function and Disability Instrument (SF-LLFDI) function subscale, handgrip strength, EuroQoL-5 Dimensions visual analogic scale (EQ5DVAS), weight, body mass index (BMI), and Short-Form Mini Nutritional Assessment (MNA-SF) at baseline and 6 and 12 weeks. Forty-eight participants (52.7%) improved at least 1 point in the SPPB at week 6, and 44 (48.4%) did so at week 12; 39 participants (42.9%) improved at least 2 points in the SF-LLFDI at week 6, and 46 (50.5%) at week 12. Participants improved their quality of life measured with the EQ5DVAS by 6% (95% confidence interval [CI] 3%-10%) at week 6, and by 5% (95% CI 0%-10%) at week 12. They also improved their nutritional status (weight gain, BMI increase, and higher MNA-SF scores at 6- and 12-week follow-up). This improvement was higher in participants with more frailty criteria, lower functional level, lower vitamin D levels, and poorer nutritional status. A 12-week intervention with oral nutritional supplementation plus physical exercise improves function, nutritional status, and quality of life in frail institutionalized older adults.

2015-06-01

The concept of oral health is frequently reduced to the absence of disease, despite existing conceptual models exploring the wider determinants of oral health and quality of life. The International Classification of Functioning, Disability and Health (ICF) (WHO) is designed to qualify functional, social and environmental aspects of health. This survey aimed to reach a consensual description of adult oral health, derived from the ICF using international professional opinion. The Global Oral Health Survey involved a two-round, online survey concerning factors related to oral health including functioning, participation and social environment. Four hundred eighty-six oral health professionals from 74 countries registered online. Professionals were pooled into 18 groups of six WHO world regions and three professional groups. In a randomised stratification process, eight professionals from each pool (n=144) completed the survey. The first round consisted of eight open-ended questions. Open expression replies were analysed for meaningful concepts and linked using established rules to the ICF. In Round 2, items were rated for their relevance to oral health (88% response rate). Eighty-nine ICF items and 30 other factors were considered relevant by at least 80% of participants. International professionals reached consensus on a holistic description of oral health, which could be qualified and quantified using the ICF. These results represent the first step towards developing an ICF Core Set in Oral Health, which would provide a practical tool for reporting outcome measures in clinical practice, for research and epidemiology, and for the improvement of interdisciplinary communication regarding oral health. Professional consensus reached in this survey is the foundation stone for developing an ICF Core Set in Oral Health, allowing the holistic aspects of oral health to be qualified and quantified. This tool is necessary to widen our approach to clinical decision making, measurement of clinical outcomes, research and epidemiology. Copyright © 2015 Elsevier Ltd. All rights reserved.

Income inequality in the United States and its potential effect on oral health.

The authors explored the relationship between income inequality and self-reported oral health and oral health-related quality of life. The authors used an online survey to gather data about US adults' perceptions of their overall oral health and how oral health affected their quality of life. The authors categorized respondents as coming from areas of low, medium, or high income inequality on the basis of a county-level Gini coefficient. Results of χ 2 tests and an analysis of variance indicated that there was a significant association between income inequality and oral health as measured by using the overall condition of the mouth and teeth, life satisfaction, and frequency of experiencing functional and social problems related to oral health. Generally, adults from areas of lower income inequality reported better oral health and oral health-related quality of life. Income inequality has the potential to affect both functional and social dimensions of oral health, possibly through a psychosocial pathway. Future research is necessary to determine whether any causal link exists. Our findings may inform oral health policy. Long-term policies designed to improve the oral health of Americans could work best when supported by policies designed to reduce levels of income inequality, and thereby, may reduce oral health inequalities. Further research is needed to examine the effectiveness of such policies. Copyright © 2017 American Dental Association. Published by Elsevier Inc. All rights reserved.

The objective of this case report was to describe the oral rehabilitation of a five-year-old boy patient diagnosed with amelogenesis imperfecta (AI) in the primary dentition. AI is a group of hereditary disorders that affects the enamel structure. The patient was brought to the dental clinic complaining of tooth hypersensitivity during meals. The medical history and clinical examination were used to arrive at the diagnosis of AI. The treatment was oral rehabilitation of the primary molars with stainless steel crowns and resin-filled celluloid forms. The main objectives of the selected treatment were to enhance the esthetics, restore masticatory function, and eliminate the teeth sensitivity. The child was monitored in the pediatric dentistry clinic at four-month intervals until the mixed dentition stage. Treatment not only restored function and esthetic, but also showed a positive psychological impact and thereby improved perceived quality of life. The preventive, psychological, and curative measures of a young child with AI were successful. This result can encourage the clinicians to seek a cost-effective technique such as stainless steel crowns, and resin-filled celluloid forms to reestablish the oral functions and improve the child's psychosocial development.

Early oral nutrition (EON) has been shown to improve recovery of gastrointestinal function, length of stay and mortality after abdominal surgery; however, early oral nutrition often fails during the first week after surgery. Here, a multi-modal early oral nutrition program is introduced to promote recovery of gastrointestinal function and tolerance of oral nutrition. Consecutive patients scheduled for abdominal surgery were randomized to the multimodal EON group or a group receiving conventional care. The primary endpoint was the time of first defecation. The secondary endpoints were outcomes and the cost-effectiveness ratio in treating infectious complications. The rate of infectious-free patients was regarded as the index of effectiveness. One hundred seven patients were randomly assigned to groups. Baseline characteristics were similar for both groups. In intention-to-treat analysis, the success rate of oral nutrition during the first week after surgery in the multimodal EON group was 44 (83.0%) versus 31 (57.4%) in the conventional care group (P = 0.004). Time to first defecation, time to flatus, recovery time of bowel sounds, and prolonged postoperative ileus were all less in the multimodal EON group (P < 0.05). The median postoperative length of stay in the multimodal EON group was 8 days (6, 12) versus 10 days (7, 18) in the conventional care group (P < 0.001). The total cost of treatment and nutritional support were also less in the multi-modal early oral nutrition group (P < 0.001). The effectiveness was 84.9 and 79.9% in the multimodal EON and conventional care group, respectively (P = 0.475). However, the cost-effectiveness ratio was USD 537.6 (506.1, 589.3) and USD 637.8 (593.9, 710.3), respectively (P < 0.001). The multi-modal early oral nutrition program was an effective way to improve tolerance of oral nutrition during the first week after surgery, decrease the length of stay and improve cost-effectiveness after abdominal surgery.

Envisioning an oral healthcare workforce for the future.

Nash, David A

2012-10-01

Health is critical to human well-being. Oral health is an integral component of health. One is not healthy without oral health. As health is essential to human flourishing, it is important that an oral healthcare delivery system and workforce be developed and deployed which can help ensure all citizens have the potential to access oral health care. As such access does not generally exist today, it is imperative to advance the realization of this goal and to develop a vision of an oral healthcare workforce to functionally support access. Public funding of basic oral health care is an important element to improving access. However, funding is only economically feasible if a workforce exists that is structured in a manner such that duties are assigned to individuals who have been uniquely trained to fulfill specific clinical responsibilities. An essential element of any cost-effective organizational system must be the shared responsibility of duties. Delegation must occur in the oral health workforce if competent, cost-effective care is to be provided. Desirable members of the oral health team in an efficient and effective system are as follows: generalist dentists who are educated as physicians of the stomatognathic system (oral physicians), specialist dentists, dental therapists, dental hygienists, dually trained hygienists/therapists (oral health therapists), oral prosthetists (denturists), and expanded function dental assistants (dental nurses). © 2012 John Wiley & Sons A/S.

[Investigation of the effect of vinpocetine on cerebral blood flow and cognitive functions].

PubMed

Valikovics, Attila

2007-07-30

Vinpocetine has been widely used in the treatment of ischaemic cerebrovascular diseases and dementias of vascular type. Chronic cerebral hypoperfusion plays an important role in the development of certain types of dementia. In consequence of complex mode of action vinpocetine plays a significant role in the improvement of cerebral hypoperfusion. The symptoms of mild cognitive impairment considered as "predementia" are similar to those of dementia, although milder. The authors investigated the characteristics of the blood flow parameters of patients with ischemic stroke and mild cognitive impairment both in resting conditions or following chemical stimulus as well as they investigated the severity of mental deterioration in the two patient groups. In a pilot study the authors examined the influence of 12-week long oral vinpocetine therapy on the blood flow parameters and cognitive functions in the two patient groups. The authors studied the blood flow velocity of a. cerebri media in resting conditions and after 30 sec of breath holding with transcranial Doppler before treatment and after a 12-week long oral vinpocetine treatment. At the same time psychometric tests (MMSE, ADAS-Cog) were used in order to examine cognitive functions, while the general condition of the patients were scored by Clinical Global Impression (CGI) scale. After a 12-week long oral vinpocetine treatment the increase of blood flow velocity in resting conditions compared to the baseline values was significant in the vascular group. The percent increase of mean velocity after the breath holding TCD test showed a significant increase compared to the baseline in both patient groups. The authors found a significant improvement of cognitive functions after a 12-week long oral vinpocetine therapy using psychometric tests. The improvement was identical in both groups. The general condition of patients improved significantly according to both the investigator's and the patients' opinion; patients with mild cognitive impairment judged the improvement higher. Vinpocetine improved the cerebrovascular reserve capacity in both patient groups and favourably influenced the cognitive status and general condition of patients with chronic hypoperfusion. The authors recommend the use of vinpocetine for the treatment of patients with mild cognitive impairment.

Leukemia is the most common neoplastic disease of the white blood cells which is important as a pediatric malignancy. Oral manifestations occur frequently in leukemic patients and may present as initial evidence of the disease or its relapse. The symptoms include gingival enlargement and bleeding, oral ulceration, petechia, mucosal pallor, noma, trismus and oral infections. Oral lesions arise in both acute and chronic forms of all types of leukemia. These oral manifestations either may be the result of direct infiltration of leukemic cells (primary) or secondary to underlying thrombocytopenia, neutropenia, or impaired granulocyte function. Despite the fact that leukemia has long been known to be associated with oral lesions, the available literature on this topic consists mostly of case reports, without data summarizing the main oral changes for each type of leukemia. Therefore, the present review aimed at describing oral manifestations of all leukemia types and their dental management. This might be useful in early diagnosis, improving patient outcomes.

Alzheimer disease (AD) can affect masticatory function, affecting oral health-related quality of life (OHRQoL). Whether oral rehabilitation with conventional removable prostheses can restore masticatory function and improve OHRQoL in these individuals is unknown. The purpose of this clinical study was to evaluate the influence of oral rehabilitation with removable prostheses on masticatory efficiency and OHRQoL in elders with and without AD. Thirty-two elders with mild AD (n=16, mean age=76.7 ±6.3 years) or without AD (n=16, mean age=75.2 ±4.4 years) were recruited. All participants first underwent masticatory efficiency and OHRQoL evaluations, and 2 months after insertion of new removable prostheses, the variables were reassessed. Masticatory efficiency was determined using the sieving method, and OHRQoL was measured by applying the Geriatric Oral Health Assessment Index (GOHAI). The data from the baseline and after insertion of the new removable prostheses were compared by paired t test. Group differences at each time point were assessed by t test (α=.05). After insertion of the new removable prostheses, masticatory efficiency and OHRQoL improved in both the elders with AD and the control. At baseline, elders with AD had lower masticatory efficiency and higher OHRQoL than controls (P<.05). After removable prosthesis insertion, elders with AD continued to show lower masticatory efficiency values than controls, but their OHRQoL was similar. Oral rehabilitation with new removable prostheses improved the masticatory efficiency and OHRQoL of elders with and without AD, although masticatory efficiency did not reach control levels in elders with AD.

Apnoea is a breathing disorder marked by the absence of airflow at the nose or mouth. In children, risk factors include adenotonsillar hypertrophy, obesity, neuromuscular disorders and craniofacial anomalies. The most common treatment for obstructive sleep apnoea syndrome (OSAS) in childhood is adenotonsillectomy. This approach is limited by its surgical risks, mostly in children with comorbities and, in some patients, by recurrence that can be associated with craniofacial problems. Oral appliances and functional orthopaedic appliances have been used for patients who have OSAS and craniofacial anomalies because they change the mandible posture forwards and potentially enlarge the upper airway and increase the upper airspace, improving the respiratory function. To assess the effectiveness of oral appliances or functional orthopaedic appliances for OSAS in children. A sensitive search was developed for the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2005, Issue 3); PubMed (January 1966 to September 2005); EMBASE (1980 to September 2005); Lilacs (1982 to September 2005); BBO-Bibliografia Brasileira de Odontologia (1986 to September 2005); and SciELO (1997 to September 2005). There was no restriction of language or source of information. All randomised or quasi-randomised controlled trials comparing all types of oral and functional orthopaedic appliances with placebo or no treatment, in children 15 years old or younger. reduction of apnoea to less than one episode per hour. dental and skeletal relationship, sleep parameters improvement, cognitive and phonoaudiologic function, behavioural problems, drop outs and withdrawals, quality of life, side effects (tolerability), economic evaluation. Data were independently extracted by two review authors. Authors were contacted for additional information. Risk ratios with 95% confidence intervals were calculated for all important dichotomous outcomes. The initial search identified 384 trials. One of them, reporting results from a total of 23 patients, was suitable for inclusion in the review. Data provided in the published report did not answer all the questions from this review, but some of them were, and the presented results favour treatment. At present there is no sufficient evidence to state that oral appliances or functional orthopaedic appliances are effective in the treatment of OSAS in children. Oral appliances or functional orthopaedic appliances may be helpful in the treatment of children with craniofacial anomalies which are risk factors for apnoea.

Contraceptive choices for women with endocrine complications.

PubMed

Loriaux, D L; Wild, R A

1993-06-01

Previous confusion regarding the interference by oral contraceptives in measurements of endocrine function have been largely eliminated by the advent of improved, more sensitive assays. There are few if any contraindications to oral contraceptive use in patients with thyroid disease. Patients with prolactinoma can be treated with bromocriptine to restore fertility and prevent mineral loss. However, as a less expensive alternative, oral contraceptives can be prescribed to correct mineral loss, because there is no convincing evidence of an adverse effect on prolactinomas by the steroidal content of the pill. Oral contraceptives comprise a near ideal treatment modality for women with polycystic ovary disease because, among other effects, oral contraceptives reduce synthesis of androgen by inhibiting pituitary gonadotropin secretion.

To investigate whether pyruvate-enriched oral rehydration solution (Pyr-ORS), compared with citrate-enriched ORS (Cit-ORS), improves hemodynamics and organ function by alleviating vasopermeability and plasma volume loss during intra-gastric fluid rehydration in dogs with severe burn. Forty dogs subjected to severe burn were randomly divided into four groups (n=10): two oral rehydrated groups with Pyr-ORS and Cit-ORS (group PR and group CR), respectively, according to the Parkland formula during the first 24h after burns. Other two groups were the intravenous (IV) resuscitation (group VR) with lactated Ringer's solution with the same dosage and no fluid rehydration (group NR). During the next 24h, all groups received the same IV infusion. The hemodynamics, plasma volume, vasopermeability and water contents and function of various organs were determined. Plasma levels of vascular endothelial growth factor (VEGF) and platelet activating factor (PAF) were detected by ELISA. Hemodynamics parameters were significantly improved in group PR superior to group CR after burns. Levels of VEGF and PAF were significantly lower in group PR than in group CR. Organ function parameters were also greatly preserved in group PR, relative to groups CR and NR. Lactic acidosis was fully corrected and survival increased in group PR (50.0%), compared to group CR (20.0%). Pyr-ORS was more effective than Cit-ORS in improving hemodynamics, visceral blood perfusion and organ function by alleviating vasopermeability-induced visceral edema and plasma volume loss in dogs with severe burn.

We previously prepared and pharmaceutically evaluated ginger orally disintegrating (OD) tablets, optimized the base formulation, and carried out a clinical trial in healthy adults in their 20 s and 50s to measure their effect on salivary substance P (SP) level and improved swallowing function. In this study, we conducted clinical trials using the ginger OD tablets in older people to clinically evaluate the improvements in swallowing function resulting from the functional components of the tablet. The ginger OD tablets were prepared by mixing the excipients with the same amount of mannitol and sucrose to a concentration of 1% ginger. Eighteen healthy older adult volunteers aged 63 to 90 were included in the swallowing function test. Saliva was collected before and 15 min after administration of the placebo and ginger OD tablets. Swallowing endoscopy was performed by an otolaryngologist before administration and 15 min after administration of the ginger OD tablets. A scoring method was used to evaluate the endoscopic swallowing. Fifteen minutes after taking the ginger OD tablets, the salivary SP amount was significantly higher than prior to ingestion or after taking the placebo (p<0.05). Among 10 subjects, one scored 1-3 using the four evaluation criteria. Overall, no aspiration occurred and a significant improvement in the swallowing function score was observed (p<0.05) after taking the ginger OD tablets. Our findings showed that the ginger OD tablets increased the salivary SP amount and improved swallowing function in older people with appreciably reduced swallowing function.

Apnoea is a breathing disorder marked by the absence of airflow at the nose or mouth. In children, risk factors include adenotonsillar hypertrophy, obesity, neuromuscular disorders and craniofacial anomalies. The most common treatment for obstructive sleep apnoea syndrome (OSAS) in childhood is adeno-tonsillectomy. This approach is limited by its surgical risks, mostly in children with comorbidities and, in some patients, by recurrence that can be associated with craniofacial problems. Oral appliances and functional orthopaedic appliances have been used for patients who have OSAS and craniofacial anomalies because they hold the lower jaw (mandible) forwards which potentially enlarges the upper airway and increases the upper airspace, improving the respiratory function. To assess the effects of oral appliances or functional orthopaedic appliances for obstructive sleep apnoea in children. We searched the following electronic databases: Cochrane Oral Health's Trials Register (to 7 April 2016); Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 3) in the Cochrane Library (searched 7 April 2016); MEDLINE Ovid (1946 to 7 April 2016); Embase Ovid (1980 to 7 April 2016); LILACS BIREME (from 1982 to 7 April 2016); BBO BIREME (from 1986 to 7 April 2016) and SciELO Web of Science (from 1997 to 7 April 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials on 7 April 2016. We placed no restrictions on the language or date of publication when searching the electronic databases. All randomised or quasi-randomised controlled trials comparing all types of oral and functional orthopaedic appliances with placebo or no treatment, in children 15 years old or younger. reduction of apnoea to less than one episode per hour. dental and skeletal relationship, sleep parameters improvement, cognitive and phonoaudiological function, behavioural problems, quality of life, side effects (tolerability) and economic evaluation. Two review authors screened studies and extracted data independently. Authors were contacted for additional information. We calculated risk ratios with 95% confidence intervals for all important dichotomous outcomes. We assessed the quality of the evidence of included studies using GRADEpro software. The initial search identified 686 trials. Only one trial, reporting the results from a total of 23 children and comparing an oral appliance to no treatment, was suitable for inclusion in the review. The trial assessed apnoea-hypopnoea, daytime symptoms (sleepiness, irritability, tiredness, school problems, morning headache, thirstiness in the morning, oral breathing and nasal stuffiness) and night-time symptoms (habitual snoring, restless sleep and nightmares measured by questionnaire). Results were inconsistent across outcomes measures and time points. The evidence was considered very low quality. There is insufficient evidence to support or refute the effectiveness of oral appliances and functional orthopaedic appliances for the treatment of obstructive sleep apnoea in children. Oral appliances or functional orthopaedic appliances may be considered in specified cases as an auxiliary in the treatment of children who have craniofacial anomalies which are risk factors for apnoea.

Intravenous administration of vitamin C has been shown to decrease oxidative stress and, in some instances, improve physiological function in adult humans. Oral vitamin C administration is typically less effective than intravenous, due in part to inferior vitamin C bioavailability. The purpose of this study was to determine the efficacy of oral delivery of vitamin C encapsulated in liposomes. On 4 separate randomly ordered occasions, 11 men and women were administered an oral placebo, or 4 g of vitamin C via oral, oral liposomal, or intravenous delivery. The data indicate that oral delivery of 4 g of vitamin C encapsulated in liposomes (1) produces circulating concentrations of vitamin C that are greater than unencapsulated oral but less than intravenous administration and (2) provides protection from ischemia–reperfusion-mediated oxidative stress that is similar to the protection provided by unencapsulated oral and intravenous administrations.

Background: Hypoxia-induced pulmonary vasoconstriction increases pulmonary arterial pressure (PAP) and may impede right heart function and exercise performance. This study examined the effects of oral nitrate supplementation on right heart function and performance during exercise in normoxia and hypoxia. We tested the hypothesis that nitrate supplementation would attenuate the increase in PAP at rest and during exercise in hypoxia, thereby improving exercise performance. Methods: Twelve trained male cyclists [age: 31 ± 7 year (mean ± SD)] performed 15 km time-trial cycling (TT) and steady-state submaximal cycling (50, 100, and 150 W) in normoxia and hypoxia (11% inspired O2) following 3-day oral supplementation with either placebo or sodium nitrate (0.1 mmol/kg/day). We measured TT time-to-completion, muscle tissue oxygenation during TT and systolic right ventricle to right atrium pressure gradient (RV-RA gradient: index of PAP) during steady state cycling. Results: During steady state exercise, hypoxia elevated RV-RA gradient (p > 0.05), while oral nitrate supplementation did not alter RV-RA gradient (p > 0.05). During 15 km TT, hypoxia lowered muscle tissue oxygenation (p < 0.05). Nitrate supplementation further decreased muscle tissue oxygenation during 15 km TT in hypoxia (p < 0.05). Hypoxia impaired time-to-completion during TT (p < 0.05), while no improvements were observed with nitrate supplementation in normoxia or hypoxia (p > 0.05). Conclusion: Our findings indicate that oral nitrate supplementation does not attenuate acute hypoxic pulmonary vasoconstriction nor improve performance during time trial cycling in normoxia and hypoxia.

Orofacial pain impairs a patient's speech, swallowing, eating and interpersonal relations. Thirty-seven patients with a premalignant oral lesion, 124 patients with oral squamous cell carcinoma (OSSC), and 21 patients with a recurrence of OSSC were evaluated for their orofacial pain. The University of California San Francisco Oral Cancer Pain Questionnaire was administered to these patients at their initial visit, before they were prescribed analgesics for pain and before any treatment. Significant differences with respect to orofacial pain between the groups could be evaluatedwere observed. Patients with recurrence had the highest facial pain and patients with precancer had the lowest. Patients with OSSC and recurrence of OSSC reported significant levels of orofacial pain and functional restriction because of pain. Moreover, patients with recurrence of OSSC experienced significantly higher function-related pain, rather than pain qualities. These findings suggest that an important predictor for recurrence of OSSC may be the onset of orofacial pain that is exacerbated during function. The present study examined orofacial pain depending on the disease severity of precancer and oral cancer patients. Earlier recognition of symptoms of OSSC may improve early detection of its recurrence.

N, N'-dihydroxybenzamdine represents a model compound for a new prodrug principle to improve the oral bioavailability of drugs containing amidine functions. The activation of the prodrug could be demonstrated in vitro by porcine and human subcellular enzyme fractions, the mitochondrial benzamidoxime reducing system, and porcine hepatocytes. In vivo, the bioavailability of benzamidine after oral application of N, N'-dihydroxybenzamidine was about 91% and exceeded that of benzamidine after oral application of benzamidoxime, being about 74% (Liu, L.; Ling, Y.; Havel, C.; Bashnick, L.; Young, W.; Rai, R.; Vijaykumar, D.; Riggs, J.

Creatine is a supplement used by sportsmen to increase athletic performance by improving energy supply to muscle tissues. It is also an essential brain compound and some hypothesize that it aids cognition by improving energy supply and neuroprotection. The aim of this systematic review is to investigate the effects of oral creatine administration on cognitive function in healthy individuals. A search of multiple electronic databases was performed for the identification of randomized clinical trials (RCTs) examining the cognitive effects of oral creatine supplementation in healthy individuals. Six studies (281 individuals) met our inclusion criteria. Generally, there was evidence that short term memory and intelligence/reasoning may be improved by creatine administration. Regarding other cognitive domains, such as long-term memory, spatial memory, memory scanning, attention, executive function, response inhibition, word fluency, reaction time and mental fatigue, the results were conflicting. Performance on cognitive tasks stayed unchanged in young individuals. Vegetarians responded better than meat-eaters in memory tasks but for other cognitive domains no differences were observed. Oral creatine administration may improve short-term memory and intelligence/reasoning of healthy individuals but its effect on other cognitive domains remains unclear. Findings suggest potential benefit for aging and stressed individuals. Since creatine is safe, future studies should include larger sample sizes. It is imperative that creatine should be tested on patients with dementias or cognitive impairment. Copyright © 2018 Elsevier Inc. All rights reserved.

2013-01-01

Objectives Oropharyngeal cancer (OPC) is the 6th most common cancer worldwide. Focus on risk factors, improved diagnostic methods and effective management strategies have made it possible to successfully treat OPC. However, the 5-year survival rate has not improved for several years due to multiple treatment complications, tissue morbidity, loss of function and diminished quality of life. Survivors are faced with complications like oral mucositis, hyposalivation, osteoradionecrosis; tissue fibrosis, morbidity from jaw resection; disfigurement and loss of function that further diminish quality of life. The aim of this review is to highlight major complications associated with treatment of OPC via a literature search and review of available options for identification and management of these complications. Data Sources Relevant publications on oral complications of OPC therapy were thoroughly reviewed from the literature published between the years 1988 and 2012. Material and Method We evaluated reported incidence, prevalence and risk factors for oral complications of chemotherapy and radiotherapy for OPC. The authors conducted electronic search using English language databases namely PubMed Plus, Medline (Pre-Medline and Medline), Cochrane Database of systematic reviews (evidence-based medicine), Dentistry & Oral sciences source, AccessScience, Embase, Evidence-Based Medicine Reviews Multifile, Google Scholar, ISI Journal Citation Reports, Ovid Multi-Database. Conclusion We identified the most common complications associated with the treatment of oral cancers. Based on the information gathered, there is evidence that survival of OPC extends beyond eradication of the diseased tissue. Understanding the potential treatment complications and utilizing available resources to prevent and minimize them are important. Caring for OPC survivors should be a multidisciplinary team approach involving the dentist, oncologist, internist and social worker to improve the currently stagnant 5-year survival rate of OPC. More emphasis on improved quality of life after elimination of the cancer will ultimately improve OPC survivorship. PMID:23444208

Oral appliances with an occlusal flat table are used as treatment dentures. However, the short-term effect of insertion of such oral appliances on chewing has not been reported. This study aimed to determine whether experimental and continuous insertion of oral appliances with an occlusal flat table has an effect on chewing efficiency and Oral Health Impact Profile (OHIP) in healthy participants. Ten participants each in the oral-appliance and control (no oral-appliance insertion) groups attended six data collection sessions for 5 consecutive days. Participants answered the OHIP questionnaire and underwent the chewing efficiency test. For each parameter, intergroup differences were investigated in terms of change from baseline to immediately after oral-appliance insertion (0 hour; P < .05) and from 0 hour to 24, 48, 72 and 96 hours after oral-appliance insertion (P < .05). There were significant differences between groups in the degree of change in chewing efficiency and OHIP scores for functional limitation, physical pain, physical disability and handicap from baseline to 0 hour (all, P < .001); among these, only OHIP scores for functional limitation and physical pain demonstrated significant differences in degree of change between the two groups at 96 hours after appliance insertion (P = .477 and .275, respectively). Differences between the two groups in the degree of change in other parameters were not significant. Insertion of oral appliances caused a decrease in chewing efficiency and an increase in OHIP scores. Continuous insertion improved functional limitation and physical pain within 96 hours. © 2017 John Wiley & Sons Ltd.

Oral insulin delivery: existing barriers and current counter-strategies.

The chronic and progressive nature of diabetes is usually associated with micro- and macrovascular complications where failure of pancreatic β-cell function and a general condition of hyperglycaemia is created. One possible factor is failure of the patient to comply with and adhere to the prescribed insulin due to the inconvenient administration route. This review summarizes the rationale for oral insulin administration, existing barriers and some counter-strategies trialled. Oral insulin mimics the physiology of endogenous insulin secreted by pancreas. Following the intestinal absorption of oral insulin, it reaches the liver at high concentration via the portal vein. Oral insulin on the other hand has the potential to protect pancreatic β-cells from autoimmune destruction. Structural modification, targeting a particular tissue/receptor, and the use of innovative pharmaceutical formulations such as nanoparticles represent strategies introduced to improve oral insulin bioavailability. They showed promising results in overcoming the hurdles facing oral insulin delivery, although delivery is far from ideal. The use of advanced pharmaceutical technologies and further research in particulate carrier system delivery predominantly nanoparticle utilization would offer useful tools in delivering insulin via the oral route which in turn would potentially improve diabetic patient compliance to insulin and the overall management of diabetes. © 2017 Royal Pharmaceutical Society.

Objectives. We evaluated the effect of an alternative dental workforce program—Kansas’s Extended Care Permit (ECP) program—as a function of changes in oral health. Methods. We examined data from the 2008 to 2012 electronic medical records of children (n = 295) in a Midwestern US suburb who participated in a school-based oral health program in which preventive oral health care was delivered by ECP dental hygienists. We examined changes in oral health status as a function of sealants, caries, restorations, and treatment urgency with descriptive statistics, multivariate analysis of variance, Kruskal–Wallis test, and Pearson correlations. Results. The number of encounters with the ECP dental hygienist had a statistically significant effect on changes in decay (P = .014), restorations (P = .002), and treatment urgency (P = .038). Based on Pearson correlations, as encounters increased, there was a significant decrease in decay (–0.12), increase in restorations (0.21), and decrease in treatment urgency (–0.15). Conclusions. Increasing numbers of encounters with alternative providers (ECP dental hygienists), such as with school-based oral health programs, can improve the oral health status of low-income children who would not otherwise have received oral health services.

Patients with oral preneoplastic lesion (OPL) have high risk of developing oral cancer. Although certain risk factors such as smoking status and histology are known, our ability to predict oral cancer risk remains poor. The study objective was to determine the value of gene expression profiling in predicting oral cancer development. Gene expression profile was measured in 86 of 162 OPL patients who were enrolled in a clinical chemoprevention trial that used the incidence of oral cancer development as a prespecified endpoint. The median follow-up time was 6.08 years and 35 of the 86 patients developed oral cancer over the course. Gene expression profiles were associated with oral cancer-free survival and used to develope multivariate predictive models for oral cancer prediction. We developed a 29-transcript predictive model which showed marked improvement in terms of prediction accuracy (with 8% predicting error rate) over the models using previously known clinico-pathological risk factors. Based on the gene expression profile data, we also identified 2182 transcripts significantly associated with oral cancer risk associated genes (P-value<0.01, single variate Cox proportional hazards model). Functional pathway analysis revealed proteasome machinery, MYC, and ribosomes components as the top gene sets associated with oral cancer risk. In multiple independent datasets, the expression profiles of the genes can differentiate head and neck cancer from normal mucosa. Our results show that gene expression profiles may improve the prediction of oral cancer risk in OPL patients and the significant genes identified may serve as potential targets for oral cancer chemoprevention.

Oral Microbiome Metabolism: From "Who Are They?" to "What Are They Doing?".

PubMed

Takahashi, N

2015-12-01

Recent advances in molecular biology have facilitated analyses of the oral microbiome ("Who are they?"); however, its functions (e.g., metabolic activities) are poorly understood ("What are they doing?"). This review aims to summarize our current understanding of the metabolism of the oral microbiome. Saccharolytic bacteria-including Streptococcus, Actinomyces, and Lactobacillus species-degrade carbohydrates into organic acids via the Embden-Meyerhof-Parnas pathway and several of its branch pathways, resulting in dental caries, while alkalization and acid neutralization via the arginine deiminase system, urease, and so on, counteract acidification. Proteolytic/amino acid-degrading bacteria, including Prevotella and Porphyromonas species, break down proteins and peptides into amino acids and degrade them further via specific pathways to produce short-chain fatty acids, ammonia, sulfur compounds, and indole/skatole, which act as virulent and modifying factors in periodontitis and oral malodor. Furthermore, it is suggested that ethanol-derived acetaldehyde can cause oral cancer, while nitrate-derived nitrite can aid caries prevention and systemic health. Microbial metabolic activity is influenced by the oral environment; however, it can also modify the oral environment, enhance the pathogenicity of bacteria, and induce microbial selection to create more pathogenic microbiome. Taking a metabolomic approach to analyzing the oral microbiome is crucial to improving our understanding of the functions of the oral microbiome. © International & American Associations for Dental Research 2015.

Dental sleep medicine is a rapidly growing field that is in close and direct interaction with sleep medicine and comprises many aspects of human health. As a result, dentists who encounter sleep health and sleep disorders may work with clinicians from many other disciplines and specialties. The main sleep and oral health issues that are covered in this review are obstructive sleep apnea, chronic mouth breathing, sleep-related gastroesophageal reflux, and sleep bruxism. In addition, edentulism and its impact on sleep disorders are discussed. Improving sleep quality and sleep characteristics, oral health, and oral function involves both pathophysiology and disease management. The multiple interactions between oral health and sleep underscore the need for an interdisciplinary clinical team to manage oral health-related sleep disorders that are commonly seen in dental practice. © 2013 John Wiley & Sons A/S.

The prognosis and functional capacity of patients with pulmonary arterial hypertension (PAH) is poor, and there is a need for safe, effective, inexpensive oral treatments. A single dose of sildenafil, an oral phosphodiesterase type-5 (PD-5) inhibitor, is an effective and selective pulmonary vasodilator in PAH. However, the long-term effects of PD-5 inhibition and its mechanism of action in human pulmonary arteries (PAs) are unknown. We hypothesized that 3 months of sildenafil (50 mg orally every 8 hours) added to standard treatment would be safe and improve functional capacity and hemodynamics in PAH patients. We studied 5 consecutive patients (4 with primary pulmonary hypertension, 1 with Eisenmenger's syndrome; New York Heart Association class II to III). Functional class improved by > or =1 class in all patients. Pretreatment versus posttreatment values (mean+/-SEM) were as follows: 6-minute walk, 376+/-30 versus 504+/-27 m, P<0.0001; mean PA pressure, 70+/-3 versus 52+/-3 mm Hg, P<0.007; pulmonary vascular resistance index 1702+/-151 versus 996+/-92 dyne x s x cm(-5) x m(-2), P<0.006. The systemic arterial pressure was unchanged, and no adverse effects occurred. Sildenafil also reduced right ventricular mass measured by MRI. In 7 human PAs (6 cardiac transplant donors and 1 patient with PAH on autopsy), we showed that PD-5 is present in PA smooth muscle cells and that sildenafil causes relaxation by activating large-conductance, calcium-activated potassium channels. This small pilot study suggests that long-term sildenafil therapy might be a safe and effective treatment for PAH. At a monthly cost of 492 dollars Canadian, sildenafil is more affordable than most approved PAH therapies. A large multicenter trial is indicated to directly compare sildenafil with existing PAH treatments.

Chronic diseases and injuries are the leading health problems in all but a few parts of the world. The rapidly changing disease patterns throughout the world are closely linked to changing lifestyles, which include diets rich in sugars, widespread use of tobacco, and increased consumption of alcohol. In addition to socio-environmental determinants, oral disease is highly related to these lifestyle factors, which are risks to most chronic diseases as well as protective factors such as appropriate exposure to fluoride and good oral hygiene. Oral diseases qualify as major public health problems owing to their high prevalence and incidence in all regions of the world, and as for all diseases, the greatest burden of oral diseases is on disadvantaged and socially marginalized populations. The severe impact in terms of pain and suffering, impairment of function and effect on quality of life must also be considered. Traditional treatment of oral diseases is extremely costly in several industrialized countries, and not feasible in most low-income and middle-income countries. The WHO Global Strategy for Prevention and Control of Noncommunicable Diseases, added to the common risk factor approach is a new strategy for managing prevention and control of oral diseases. The WHO Oral Health Programme has also strengthened its work for improved oral health globally through links with other technical programmes within the Department for Noncommunicable Disease Prevention and Health Promotion. The current oral health situation and development trends at global level are described and WHO strategies and approaches for better oral health in the 21st century are outlined.

The effect of oral administration of probiotic bacteria cell walls (PBCWs) in the stimulation of the immune system in healthy BALB/c mice was evaluated. We focused our investigation mainly on intestinal epithelial cells (IECs) which are essential for coordinating an adequate mucosal immune response and on the functionality of macrophages. The probiotic bacteria and their cell walls were able to stimulate the IECs exhibiting an important activation and cytokine releases. Supplementation with PBCWs promoted macrophage activation from peritoneum and spleen, indicating that the PBCWs oral administration was able to improve the functionality of the macrophages. In addition, the PBCWs increased immunoglobulin A (IgA)-producing cells in the gut lamina propria in a similar way to probiotic bacteria, but this supplementation did not have an effect on the population of goblet cells in the small intestine epithelium. These results indicate that the probiotic bacteria and their cell walls have an important immunoregulatory effect on the IECs without altering the homeostatic environment but with an increase in IgA+ producing cells and in the innate immune cells, mainly those distant from the gut such as spleen and peritoneum. These findings about the capacity of the cell walls from probiotic bacteria to stimulate key cells, such as IECs and macrophages, and to improve the functioning of the immune system, suggest that those structures could be applied as a new oral adjuvant.

Objectives: To evaluate masticatory efficiency (ME) and oral health-related quality of life (OHRQoL) in patients rehabilitated with implant-retained mandibular overdentures. Methods: In this randomized controlled clinical trial, 50 edentulous patients visiting the Implant Center and Department of Prosthodontics, West China College of Stomatology, Sichuan University, Chengdu, China between June 2010 and June 2012 were selected and received 2 implant-retained mandibular overdenture treatments. All patients were rehabilitated with maxillary complete dentures. The ME and OHRQoL were determined both one month before the mandibular complete denture was anchored to the osseointegrated implants, and 6 months after anchoring. Paired t-tests were used to compare means of ME, and oral health impact profile-49 (OHIP-49) domains scores between pre- and post-implant. Linear regression models were utilized to seek correlations between ME and OHIP domains scores. Results: The ME increased from pre- to post-implant retained mandibular overdentures significantly (p<0.001). The total OHIP score and 4 subscales scores were changed significantly from pre- to post-implant; namely, functional limitation, psychological discomfort, physical disability, and physical pain. The total OHIP score, functional limitation, physical disability, and physical pain subscale scores were related to ME. Conclusion: Implant-retained mandibular over dentures can significantly improve patients’ ME and OHRQoL. The improvement in OHRQoL is mainly because of the improved ME. An improved chewing experience, and pain relief also contributes to improvement of OHRQoL. PMID:25316463

Dental diseases have detrimental effects on the functionality and quality of life of individuals. In addition, a strong relationship has been established between various oral and systemic diseases. In fact, the prevention and treatment of dental caries and periodontal disease have been shown to reduce the risk of diabetes and heart disease significantly. This goes beyond the role of oral health as a means to identify early manifestations of systemic diseases in the oral cavity. It highlights the necessity of maintaining an optimal oral hygiene to significantly modify the risk factors for serious systemic diseases. The use of oil pulling can be frequently found in ancient medical text and is supported by recent studies for its efficacy and long-term use for maintaining and improving oral health. This article provides an overview on the concept of oil pulling or oil swishing, its mechanism of action and a summary of the evidence available, which highlights the role of oil pulling in specific oral diseases. The goal of this review is to highlight the ancient procedure that has the potential to be used as an adjunct to conventional chemical means of dental plaque control, such as mouth rinses. Incorporating oil swishing as a component of daily oral hygiene can significantly improve oral and general health, specifically in lower socioeconomic groups and rural communities that may have interrupted access to health-care services and dental products such as dentifrices and mouth washes due to various factors; availability and affordability being the most important.

Background This paper describes the oral healthcare system and disease situation amongst children in Turkey. Considering the high prevalence and severity of dental caries, a proposal for improvement of oral health in this population group is formulated. Discussion A virtual absence of palliative, preventive and restorative care characterises juvenile oral healthcare in Turkey. Consequently, carious cavities remain untreated, which may lead to pain, discomfort and functional limitation and, further, may impact negatively upon general health and cognitive development. As a first step to controlling dental caries, a national health programme including promotional, preventive and minimal intervention approaches for managing dental caries is proposed. The pros and cons of community-oriented caries-preventive measures are discussed. Daily tooth brushing with fluoridated toothpaste at home, in mother- and child-care centres, kindergartens, and schools is highlighted. Summary The dental profession, government, university officials and other stakeholders need to meet and determine how best the oral health of children in Turkey can be improved. The present proposed plan is considered a starting point. PMID:19939240

2018-05-01

The impact of conventional prosthetic treatment on both the objective and subjective assessments of mastication as well as on well-being is unclear. The purpose of this clinical study was to compare the impact on oral health-related quality of life and masticatory function in participants treated with conventional dental prostheses. A total of 72 patients requiring prosthetic rehabilitation were enrolled by referral from the Faculty of Dentistry at the University of Granada, Spain. At baseline, demographic, behavioral, and clinical (prosthetic status, occlusal units) data were collected. In addition, the scores for quality of life, oral satisfaction, masticatory ability (Leake index), and masticatory performance (after 5, 10, and 15 cycles of bicolored chewing gum) were obtained. These records were obtained again at 6 to 8 weeks after insertion of the prostheses. The findings revealed that patients treated with fixed prostheses had better quality of life and better masticatory function than patients treated with removable prostheses. This result was even more pronounced for those treated with complete dentures. For all items, most of the treated patients improved the quality of life (average, 8.6 of the 4 items), although only between 5% and 15% of patients, especially those with a removable prosthesis, commented on functional impact after receiving treatment. Generally, masticatory performance was improved between 7% and 18% and was highly correlated not only with the number of natural teeth (r=0.61) and occlusal units (r=0.51) but also with subjective variables such as mastication satisfaction (r=0.31), impact on quality of life (r=0.30), or masticatory ability (r=0.30). Treatment with fixed prostheses achieved better results regarding quality of life, oral satisfaction, and masticatory function than treatment with removable prostheses. A moderate but significant correlation exists between the objective and subjective assessments of the masticatory functions.

Recent evidence suggests that immune cells play an important role in differentiation of inflammatory macrophages in adipose tissue, which contributes to systemic chronic inflammation. Dietary ribonucleic acid (RNA) has been shown to modulate immune function. We hypothesized that RNA affects immune cell function in adipose tissue and then improves inflammatory response in adipose tissue. C57/BL6 mice and recombination activating gene-1 (RAG-1) knockout mice on a C57BL/6 mice background were fed a high-fat diet containing 1% RNA for 12 wk. An oral glucose tolerance test was performed. Supplementation of dietary RNA in C57BL/6 mice fed a high-fat diet resulted in a smaller area under the curve (AUC) after oral glucose administration than that for control mice. The mRNA expression levels of inflammation-related cytokines in adipose tissue and serum interleukin-6 levels were reduced by dietary RNA supplementation. Interestingly, reduction of the AUC value by RNA supplementation was abolished in T and B cell-deficient RAG-1 knockout mice. These results indicate that RNA improves inflammation in adipose tissue and reduces the AUC value following oral glucose administration in a T and B cell-dependent manner.

Maintaining oral function in patients undergoing glossectomy boosts interventions such as prosthetic rehabilitation. However, current literature still fails in the presentation of results of prosthetic rehabilitation in relation to speech or swallowing. The objective of this research is to evaluate the effectiveness of prosthetic rehabilitation on voice, speech, and swallowing in patients undergoing glossectomy by performing a systematic literature review and meta-analysis of individual cases. Studies were identified by relevant electronic database and included all dates available. The criteria used were sample with any n; resection due to malignant tumors, restricted to tongue and/or floor of mouth; type of prosthetic rehabilitation; and description of the oral functions outcomes with prosthesis. For the meta-analysis of individual data, associations between the variables of interest and the type of prosthesis were evaluated. Thirty-three of 471 articles met the selection criteria. Results on speech and/or voice and swallowing were reported in 27 and 28 articles, respectively. There were improvement of speech intelligibility and swallowing in 96 patients and in 73 patients, respectively, with prosthesis. Based on the available evidences, this article showed that prosthetic rehabilitation was able to improve oral functions and can be a strategy used with surgical reconstruction in selected cases.

To clarify the relationship between masticatory performance and oral health-related quality of life (OHRQoL) before and after complete denture treatment. Thirty patients wearing complete dentures were asked to chew a gummy jelly on their habitual chewing side, and the amount of glucose extraction during chewing was measured as the parameter of masticatory performance. Subjects were asked to answer the Oral Health Impact Profile (OHIP-J49) questionnaire, which consists of 49 questions related to oral problems. The total score of 49 question items along with individual domain scores within the seven domains (functional limitation, pain, psychological discomfort, physical disability, psychological disability, social disability and handicap) were calculated and used as the parameters of OHRQoL. These records were obtained before treatment and 3 months after treatment. Each parameter of masticatory performance and OHRQoL was compared before treatment and after treatment. The relationship between masticatory performance and OHRQoL was investigated, and a stepwise multiple linear regression analysis was performed. Both masticatory performance and OHRQoL were significantly improved after treatment. Furthermore, masticatory performance was significantly correlated with some parameters of OHRQoL. The stepwise multiple linear regression analysis showed functional limitation and pain as important factors affecting masticatory performance before treatment and functional limitation as important factors affecting masticatory performance after treatment. These results suggested that masticatory performance and OHRQoL are significantly improved after treatment and that there is a close relationship between the two. Moreover, functional limitation was found to be the most important factor affecting masticatory performance. Copyright © 2018 Japan Prosthodontic Society. Published by Elsevier Ltd.

Anthracycline-based chemotherapies for breast cancer are known to adversely affect patients' quality of life (QOL) and immune function. For that reason, adjuvants that improve those impairments are required. A randomized double-blind study was conducted to evaluate the effectiveness of Lentinula edodes mycelia extract (LEM), which is an oral biological response modifier (BRM) medicine for cancer patients as such an adjuvant. A total of 47 breast cancer patients who were scheduled to receive postoperative adjuvant anthracycline-based chemotherapy, i.e., 5-fluorouracil (5-FU) + cyclophosphamide + epirubicin (FEC regimen), 5-FU + cyclophosphamide + doxorubicin/pirarubicin (FAC regimen), cyclophosphamide + doxorubicin/pirarubicin (AC regimen) and cyclophosphamide + epirubicin (EC regimen), were entered in the study. The patients were randomly divided into either an LEM or a placebo tablet group; the tablets were orally ingested daily over 2 courses of each therapy. In the placebo group, the total scores for QOL were lower on day 8 of the second course of chemotherapy compared with the baseline scores, whereas in the LEM group the scores had not decreased. In the placebo group, the QOL functional well-being score was lower on day 8 after both the first and second courses of chemotherapy compared with the baseline score, but it had not decreased in the LEM group. Evaluation of immunological parameters indicated that an increase in the proportion of regulatory T cells to peripheral blood CD4 + cells tended to be inhibited in the LEM group compared with the placebo group. Oral LEM that was coadministered with anthracycline-based chemotherapies was useful for maintaining patients' QOL and immune function. Thus, LEM appears to be a useful oral adjuvant for patients receiving anthracycline-based chemotherapy.

Advanced-stage Parkinson's disease (PD) strongly affects quality of life (QoL). Continuous intraduodenal administration of levodopa (IDL) is efficacious, but entails high costs. This study aims to estimate these costs in routine care. 10 patients with advanced-PD who switched from oral medication to IDL were assessed at baseline, and subsequently at 3, 6, 9 and 12 months follow-up. We used the Unified PD Rating Scale (UPDRS) for function and 15D for Quality of Life (QoL). Costs were assessed using quarterly structured patient questionnaires and hospital registries. Costs per quality adjusted life year (QALY) were estimated for conventional treatment prior to switch and for 1-year treatment with IDL. Probabilistic sensitivity analysis was based on bootstrapping. IDL significantly improved functional scores and was safe to use. One-year conventional oral treatment entailed 0.63 QALY while IDL entailed 0.68 (p > 0.05). The estimated total 1-year treatment cost was NOK419,160 on conventional treatment and NOK890,920 on IDL, representing a cost of NOK9.2 million (€1.18 mill) per additional QALY. The incremental cost per unit UPDRS improvement was NOK25,000 (€3,250). Medication was the dominant cost during IDL (45% of total costs), it represented only 6.4% of the total for conventional treatment. IDL improves function but is not cost effective using recommended thresholds for cost/QALY in Norway.

To determine the success rate, oral morbidity and functional outcomes of redo buccal mucosa graft urethroplasty (BMGU) for treatment of stricture recurrence after previous BMGU. We included 50 patients who underwent redo BMGU between February 2009 and September 2014. Patients' charts and non-validated questionnaires were reviewed. The primary endpoint was success rate, defined as stricture-free survival. Stricture recurrence was defined as any postoperative claims of catheterization, dilatation, urethrotomy or repeat urethroplasty, or a maximum urinary flow rate <15 mL/s, and a stricture was consecutively verified in a combined cysto-urethrogram or cystoscopy at annual follow-up visit. The secondary endpoint was oral morbidity. Additional endpoints were erectile function, urinary continence and patients' satisfaction. Redo BMGU was performed for bulbar (71.4%) or penile (28.6%) recurrent strictures. The mean (median; range) follow-up was 25.6 (15.5; 3-70) months. Stricture recurrence occurred in 18.0% of patients within a mean (median; range) of 13.8 (9.0; 3-36) months. Stricture-free survival at 12, 24 and 36 months was 91.2, 86.2 and 80.8%, respectively. The majority of the patients (97.0%) reported no or only mildly changed salivation or problems in opening of the mouth. Severe or very severe oral numbness occurred in 13.5% of patients. Oral problems in daily life were a moderate or severe burden to 13.6 and 2.7% of the patients, respectively, while 75.0% of the patients reported improved quality of life compared with preoperative status. The success rate and oral morbidity of redo BMGU are almost the same as outcomes of primary BMGU. Oral numbness was the most frequently reported oral disorder. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

Oral health in old persons is frequently poor; non-functional prostheses are common and negatively affect quality of life. The objective of this study was to estimate the impact of oral health problems on oral health related quality of life in a sample of home dwelling Mexican elders. Household survey in 655 persons 70 years old and over residing in one county in Mexico City. Oral Health Related Quality of Life (Short version of the Oral Health Impact Profile validated in Mexico-OHIP-14-sp), self-perception of general and oral health, xerostomia, utilization of dental services, utilization and functionality of removable dental prostheses, dental and periodontal conditions, age, gender, marital status, schooling, depression, cognitive impairment and independence in activities of daily living (ADL). A negative binomial regression model was fitted. Mean age was 79.2 ± 7.1 years; 54.2% were women. Mean OHIP-14-Sp score was 6.8 ± 8.7, median was 4. The final model showed that men (RR = 1.30); persons with xerostomia (RR = 1.41); no utilization of removable prostheses (RR = 1.55); utilization of non-functional removable prostheses (RR = 1.69); fair self-perception of general health (RR = 1.34); equal (RR = 1.43) or worse (RR = 2.32) self-perception of oral health compared with persons of the same age; and being dependent for at least one ADL (RR = 1.71) increased the probability of higher scores of the OHIP-14-sp. Age, schooling, depression, cognitive impairment and periodontal conditions showed no association. Oral rehabilitation can improve quality of life, health education and health promotion for the elder and their caregivers may reduce the risk of dental problems.

2016-01-01

Oral delivery is the most accepted and economical route for drug administration and leads to substantial reduction in dosing frequency. However, this route still remains a challenge for the pharmaceutical industry due to poorly soluble and permeable drugs leading to poor oral bioavailability. Incorporating bioactives into nanostructured lipid carriers (NLCs) has helped in boosting their therapeutic functionality and prolonged release from these carrier systems thus providing improved pharmacokinetic parameters. The present review provides an overview of noteworthy studies reporting impending benefits of NLCs in oral delivery and highlights recent advancements for developing engineered NLCs either by conjugating polymers over their surface or modifying their charge to overcome the mucosal barrier of GI tract for active transport across intestinal membrane.

This study was designed to compare efficacy of local administration of a nonsteroidal anti-inflammatory drug with systemic administration in patients with osteoarthritis (OA) of the knee. For this purpose, intra-articular tenoxicam and oral tenoxicam therapies were applied and the improvement in control of pain and physical functioning were evaluated. A total of 69 patients with OA of the knee were randomized into three groups. Patients in the first group (41 knees of 23 patients) were treated for 1-3 weeks with once weekly intra-articular injection of tenoxicam 20 mg. Patients in the second group (45 knees of 26 patients) received 20 mg/day tenoxicam orally for 3 weeks and only physical exercises were applied to the third group (32 knees of 20 patients). Physical examination of the knee joint, Western Ontario and McMaster Universities Index and the Lequesne Algofunctional Index were used as outcome measurements at baseline, and the 1st, 3rd and 6th months. More significant improvement in pain and disability parameters was observed in groups 1 and 2 than group 3 compared with baseline measures. Among the patients' responses a few of the differences were statistically significant, more in favour of tenoxicam, and tenoxicam seemed to be superior to exercise alone especially at the final evaluation. There was no significant difference between the oral and intra-articular tenoxicam treatment regimens. The results of this study showed that treatment of OA of the knee with intra-articular tenoxicam is as effective as that with oral tenoxicam. It can be thought that intra-articular administration can be preferred to oral therapy due to minimal possibility of systemic side effects.

The treatment of patients with oral cancer is complex: a multidisciplinary approach needs to be taken and maxillofacial and oral surgeons, an oncologist, a prosthodontist should be included, and a psychologist is often needed. This case report describes the prosthetic rehabilitation of a patient after surgical removal of oral cancer with obturator prosthesis. Resection cavity was located in central part of the hard palate and the condition belonged to Aramany class 3 maxillary defects. The two-step impression technique of denture bearing area was used and the resection of cavity was performed. A primary impression-the impression of denture bearing area was made using irreversible hydrocolloid material, while the second impression - the impression of resection cavity was made using condensation silicone material and obturator prosthesis framework. The obturator prosthesis replaced lost teeth, improved oral function and esthetics at minimal costs.

Purpose Skin aging is a progressive and degenerative process caused by a decrease in the physiological functions of the skin tissue. In addition, environmental factors as well as concomitant diseases and lifestyle (nutrition, sedentary lifestyle, smoking, etc) negatively impact the aging process. An association between oral administration of collagen peptides combined with vitamin C and extracts of Hibiscus sabdariffa and Aristotelia chilensis (Delphynol®) (Eximia Firmalize Age complex®) on dermal thickness was studied and the improvement in aging signs was evaluated. Patients and methods Female adult patients received an oral nutritional supplement containing collagen peptides, vitamin C, H. sabdariffa, and A. chilensis (Delphynol) in a sachet and were instructed to consume 1 sachet diluted in 200 mL of water once daily for 12 weeks. They were evaluated clinically, by high frequency ultrasound and cutometry. Results There was a significant improvement of firmness and elasticity and an increase in dermal thickness by ultrasound after 3 months of use. Conclusion The association of collagen peptides, vitamin C, H. sabdariffa and A. chilensis (Delphynol) could improve the signs of dermal skin aging. PMID:29750046

Patients with mild to moderate obstructive sleep apnoea (OSA) may be managed with different treatment options. This study compared the effectiveness of three commonly used non-surgical treatment modalities. Subjects with mild to moderate OSA were randomised to one of three treatment groups for 10 weeks: conservative measures (sleep hygiene) only, continuous positive airways pressure (CPAP) in addition to conservative measures or an oral appliance in addition to conservative measures. All overweight subjects were referred to a weight-reduction class. OSA was assessed by polysomnography. Blood pressure was recorded in the morning and evening in the sleep laboratory. Daytime sleepiness was assessed with the Epworth Sleepiness Scale. Health-related quality of life (HRQOL) was assessed with the 36-Item Short-Form Health Survey (SF-36) and Sleep Apnoea Quality of Life Index (SAQLI). 101 subjects with a mean (SEM) apnoea-hypopnoea index (AHI) of 21.4 (1.1) were randomised to one of the three groups. The severity of sleep-disordered breathing was decreased in the CPAP and oral appliance groups compared with the conservative measures group, and the CPAP group was significantly better than the oral appliance group. Relief from sleepiness was significantly better in the CPAP group. CPAP was also better than the oral appliance or conservative measures in improving the "bodily pain" domain, and better than conservative measures in improving the "physical function" domain of SF-36. Both CPAP and the oral appliance were more effective than conservative measures in improving the SAQLI, although no difference was detected between the CPAP and oral appliance groups. CPAP and the oral appliance significantly lowered the morning diastolic blood pressure compared with baseline values, but there was no difference in the changes in blood pressure between the groups. There was also a linear relationship between the changes in AHI and body weight. CPAP produced the best improvement in terms of physiological, symptomatic and HRQOL measures, while the oral appliance was slightly less effective. Weight loss, if achieved, resulted in an improvement in sleep parameters, but weight control alone was not uniformly effective.

We hypothesized that supplementation with trehalose, a disaccharide that reverses arterial aging in mice, would improve vascular function in middle-aged and older (MA/O) men and women. Thirty-two healthy adults aged 50-77 years consumed 100 g/day of trehalose (n=15) or maltose (n=17, isocaloric control) for 12 weeks (randomized, double-blind). In subjects with Δbody mass less than 2.3kg (5 lb.), resistance artery endothelial function, assessed by forearm blood flow to brachial artery infusion of acetylcholine (FBFACh), increased ~30% with trehalose (13.3±1.0 vs. 10.5±1.1 AUC, P=0.02), but not maltose (P=0.40). This improvement in FBFACh was abolished when endothelial nitric oxide (NO) production was inhibited. Endothelium-independent dilation, assessed by FBF to sodium nitroprusside (FBFSNP), also increased ~30% with trehalose (155±13 vs. 116±12 AUC, P=0.03) but not maltose (P=0.92). Changes in FBFACh and FBFSNP with trehalose were not significant when subjects with Δbody mass ≥ 2.3kg were included. Trehalose supplementation had no effect on conduit artery endothelial function, large elastic artery stiffness or circulating markers of oxidative stress or inflammation (all P>0.1) independent of changes in body weight. Our findings demonstrate that oral trehalose improves resistance artery (microvascular) function, a major risk factor for cardiovascular diseases, in MA/O adults, possibly through increasing NO bioavailability and smooth muscle sensitivity to NO.

This study aims to evaluate the quality of life (QOL) of patients who underwent resection of oral cancer and reconstruction by free anierolateral thigh perforator flaps (ALTF). A total of 32 patients with oral and maxillofacial malignancies who had undergone the resection of oral cancer and reconstruction by ALTF were retrospectively analyzed. At 12 months postoperatively, the QOL of these patients was assessed by using the 14-item oral health impact profile (OHIP-14) and the medical outcome study short form-36 (SF-36) questionnaires. A total of 32 questionnaires were collected. In SF-36, the highest scoring domains were bodily pain (78.58 ± 14.82), physical functioning (72.08 ± 27.86), and the role of physical (60.00 ± 42.63), whereas the lowest scoring domains were role-emotional (41.67 ± 39.62), followed by mental health (50.75 ± 13.07) and health transition (54.17 ± 21.75). In OHIP-14, the lowest scoring domains were social disability (34.50 ± 11.32) and handicap (36.04 ± 12.05), indicating the functional recovery was better; and the highest scoring domains were physical pain (73.50 ± 18.96) and psychological discomfort (60.17 ± 20.66), indicating the functional recovery was worse. The ALTF is an ideal selection for the reconstruction of oral defects after cancer resection. In using this flap, the basic social need of patients after surgery can be satisfied. Moreover, the appearance and the functions of chewing, deglutition, and speech can be restored in varying degrees. Thus, ALTF can improve the patients' QOL.

To assess changes in the oral health-related quality of life (OHRQoL), after comprehensive oral rehabilitation under general anaesthesia (CORGA), among children (i) <6 years using the Early Childhood Oral Health Impact Scale (ECOHIS) and (ii) aged 6-14 years using the child oral health-related quality of life (COHRQoL) instrument. A total of 136 healthy children who had CORGA were recruited over a period of 12 months. The parent or caregiver of the study participants completed the age-appropriate questionnaire prior to the dental treatment and at the subsequent follow-up appointments (2 weeks and 3 months). Data were analysed using repeated-measures anova and Bonferroni tests. The overall ECOHIS scores decreased significantly (P < 0.001) demonstrating large effect sizes. The greatest decreases were for the domains of child oral symptoms (57.5%) and psychology (38.7%) in the child impact section (CIS) and for the domain of parental distress (38.9%) and family function (40%) in the family impact section (FIS). For COHRQoL, the overall P-CPQ and FIS scores decreased significantly for all items (P < 0.001), demonstrating large effect sizes. The greatest decreases were for the domains of oral symptoms (77.7%), functional limitations (74.3%), and the FIS (80.1%). The OHRQoL of children in both age groups (<6 and 6-14 years) was significantly improved after CORGA. © 2015 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A comparison of neuromuscular electrical stimulation and traditional therapy, versus traditional therapy in patients with longstanding dysphagia.

2018-06-01

Dysphagia in adults arises from a range of causes including acquired neurological disorders and some cancers. Previous research has suggested that treatment using neuromuscular electrical stimulation (NMES) when used in conjunction with conventional therapy is effective. This review describes the recent literature and a small prospective case series carried out in the United Kingdom. This study contributed to support National Institute of Clinical Excellence (NICE) guidance for clinicians who wish to include NMES in a rehabilitation programme for dysphagic patients, specifically with reference to safety and the impact on swallowing function of this intervention. In 2014, the UK NICE issued guidelines enabling UK therapists to trial the use of NMES, but the guidelines also sought additional evidence on the impact on swallowing function of NMES and the incidence of side effects. This small prospective case series investigated both of these aspects with a group of patients with dysphagia of neurological origin who had not achieved adequate swallowing function with traditional therapy alone. This study recruited 10 adult patients with dysphagia of neurological origin. All had previously received traditional swallowing therapy for at least 6 months but only achieved a Functional Oral Intake Scale of 4 or less (a scale for amounts and types of oral intake). The total study period was 10 weeks for each subject comprising 5 weeks of traditional therapy delivered three times a week followed by 5 weeks of NMES concurrent with traditional therapy (NMES + traditional therapy) delivered three times a week using the VitalStim stimulator (VitalStim Therapy, UK). In addition, the Quality of Life in Swallowing and Eating Assessment Tool 10 (quality of life scales) were determined to allow comparison between studies. Nine subjects achieved an improvement in swallowing function after NMES + traditional therapy was measured using the Functional Oral Intake Scale, giving a statistically significant improvement (P < 0.001) when NMES + traditional therapy was compared with traditional therapy. In addition, there was a low incidence of adverse effects with only minor adverse events occurring in 1.3% of electrode pair placements. The current preliminary study suggests that NMES + traditional therapy has a good safety record and may improve oral intake and patient reported swallowing outcomes for subjects with long-standing dysphagia of neurological cause, which has not responded to traditional therapy. Provided care is taken with skin preparation and electrode placement the risk of adverse effects from the treatment was minimal. Significantly, in 30% of the subjects, an improvement in voice quality was found.

The aim of this study was to evaluate the relationship between malocclusion and self-perception of oral appearance/function, in 12/15-year-old Brazilian adolescents. The cluster sample consisted of 717 teenagers attending 24 urban public (n=611) and 5 rural public (n=107) schools in Maringá/PR. Malocclusion was measured using the Dental Aesthetic Index (DAI), in accordance with WHO recommendations. A parental questionnaire was applied to collect information on esthetic perception level and oral variables related to oral health. Univariate and multiple logistic regression analyses were performed. Multiple logistic regression confirmed that for 12-year-old, missing teeth (OR=2.865) and presence of openbite (open occlusal relationship) (OR=2.865) were risk indicators for speech capability. With regard to 15-year-old, presence of mandibular overjet (horizontal overlap) (OR=4.016) was a risk indicator for speech capability and molar relationship (OR=1.661) was a risk indicator for chewing capability. The impact of malocclusion on adolescents' life was confirmed in this study. Speech and chewing capability were associated with orthodontic deviations, which should be taken into consideration in oral health planning, to identify risk groups and improve community health services.

Extensive studies have shown that older people are negatively impacted by impaired eating and nutrition. The abilities to eat, enjoy food, and participate in social activities associated with meals are important aspects of health-related quality of life (HRQoL) and recovery after illness. This project aims to (i) describe and analyze relationships between oral health and oral HRQoL, swallowing ability, eating ability, and nutritional risk among older individuals admitted to short-term care; (ii) compare the perceptions that older individuals and staff report on care quality related to oral hygiene and eating; and (iii) study the feasibility and effects of a training program for people with impaired swallowing (i.e., dysphagia). This project consists of two parts, which will be performed in five Swedish counties. It will include approximately 400 older individuals and 200 healthcare professionals. Part 1 is a cross-sectional, descriptive study of older people admitted to short-term care. Subjects will be assessed by trained professionals regarding oral health status, oral HRQoL, eating and nutritional risk, and swallowing ability. Swallowing ability will be measured with a teaspoon test and a swallowing capacity test (SCT). Furthermore, subjects and staff will complete a questionnaire regarding their perceptions of care quality. Part 2 is a cluster randomized intervention trial with controls. Older participants with dysphagia (i.e., SCT <10 ml/s, measured in part 1) will be recruited consecutively to either the intervention or control group, depending on where they were admitted for short-term care. At baseline, all subjects will be assessed for oral health status, oral HRQoL, eating and nutritional risk, swallowing ability, and swallowing-related QoL. Then, the intervention group will receive 5 weeks of training with an oral screen for neuromuscular training focused on orofacial and pharyngeal muscles. After completing the intervention, and at six months post-intervention, all assessments will be repeated in both study groups. The results will make important contributions to rehabilitation knowledge, including approaches for improving swallowing function, oral health, and food intake and for improving the quality of oral care for older people. This trial was retrospectively registered at ClinicalTrials.gov, on July 4, 2016, identifier: NCT02825927 .

This study was undertaken to investigate the clinical features of oral motor dysfunction and feeding problems as well as the nutritional status of children with cerebral palsy (CP). Fifty-nine CP children, 39 boys and 20 girls, mean age 31 months (20 to 72 months), were recruited. Their parents were interviewed for high risk factors and feeding history. Each case was assessed for oral motor and feeding problems based on oral motor and feeding skill score; for nutritional status by measurement of weight, height; neurologically for type of cerebral palsy and for developmental age by Gesell's developmental scale. Equal number of age and sex matched controls were included for comparison of nutritional status, oral motor and feeding skill score. Among 59 patients, 51 cases had oral motor dysfunction and 55 cases had feeding problems including all athtosis, spastic tetraplegia, and 16 had spastic diplegia. The scores of both the mean oral motor function and feeding skill of CP children were significantly lower than those of the controls (P < 0.001). Main food of children with cerebral palsy consisted of liquid and semisolid diet. Body weight and height below the 25th percentile were found in 13 cases and 19 cases, respectively. The majority of the children with cerebral palsy had oral motor dysfunction and feeding problems which appeared in early age and disturbed the growth and nutritional status. Thorough assessment for oral motor function, feeding problems and nutritional status of CP children is indicated in order to start timely rehabilitation and nutritional interventions which can significantly improve their nutritional status and quality of life.

Dental infections, frequent in the general population, are a common cause of inflammation with systemic impact, and are the most common cause of orofacial pain. Temporomandibular disorders are also frequent in the elderly and represent an important cause of secondary headache. Both inflammation and pain can also contribute to cognitive, functional and behavioral impairment of the elderly and aggravate symptoms of patients with Alzheimer’s disease (AD). We report a case of a 74-year-old woman with AD and chronic facial pain who had a significant improvement in functional activities as well as in cognition and depressive symptoms after successful treatment of her facial pain. Patients with AD have higher compromise of oral health with infections and teeth loss. The investigation of orofacial pain should be performed in patients with AD, because of the associations reviewed and given the potential for improvement as highlighted by this case. PMID:29213678

To investigate the effects of using intra and extra circumoral exercise on subjective and objective parameters of pre- and postoral health of older people living in nursing homes. Oral health problems, such as dry mouth and halitosis, are very common complaints for older people and might be the cause of a physiological, psychological or social handicap. In an ageing society, a simple and convenient nursing intervention is needed to resolve these oral health problems without side effects. The present study adopted a pre- and posttest non-equivalent control group in a quasi-experimental design. A total of 41 older people (experimental group 21, control group 20) living in nursing homes participated in intra and extra circumoral exercise (25 min a day, six times per week for 4 weeks) to improve oral health in 2013. Chi-square test/Fisher's exact test, t-test/Mann-Whitney U-test and analysis of covariance were used for the data analysis. ancova was used to control the covariates (age and the basic values of dependent variables) to identify the effect of intra and extra circumoral exercise on the oral health between the two groups. Dry mouth symptoms decreased, oral motor function improved, salivary secretion and mouth opening size increased, salivary pH improved, halitosis decreased more in the experimental group than in the control group. However, the salivary IgA was not significantly different between the two groups. The intra and extra circumoral exercises as an independent nursing intervention can effectively promote oral health of older people. © 2016 John Wiley & Sons Ltd.

Adherence to oral naltrexone has been poor and can be improved somewhat with behavioral therapy. We compared behavioral naltrexone therapy (BNT) to compliance enhancement (CE) and tested efficacy of single-dose injection naltrexone (XR-NTX; 384 mg) with behavioral therapies at further improving adherence to oral naltrexone. A 24-week, randomized, placebo-controlled trial (n=125) compared four treatment conditions following inpatient detoxification and oral naltrexone induction: (1) BNT+XR-NTX; (2) BNT+placebo injection; (3) CE+XR-NTX; and (4) CE+placebo injection. All participants were maintained on oral naltrexone throughout the trial. Primary outcome was retention in treatment. Of 89 randomized participants, 78.7% (70/89) completed 4 weeks, 58.2% (54/89) completed 8 weeks, 47.2% (42/89) completed 12 weeks, and 25.8% (23/89) completed 24 weeks. A Cox proportional hazards regression modeled time to dropout as a function of treatment condition, baseline opioid dependence severity (bags per day of heroin use), and their interaction. Interaction of conditions by baseline severity was significant (X3(2)=9.19, p=0.027). For low-severity patients (≤ 6 bags/day), retention was highest in the BNT-XR-NTX group (60% at 6 months), as hypothesized. For high-severity (>6 bags/day) patients, BNT-XR-NTX did not perform as well, due to high early attrition. For low-severity heroin users, single-dose XR-NTX improved long-term treatment retention when combined with behavioral therapy. In higher-severity opioid-dependent patients, XR-NTX was less helpful, perhaps because, combined with oral naltrexone, it produced higher blood levels and more withdrawal discomfort. When cost considerations recommend oral naltrexone following XR-NTX, the latter should be phased in slowly. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

2018-01-29

To explore Australian speech-language pathologists' use of non-speech oral motor exercises, and rationales for using/not using non-speech oral motor exercises in clinical practice. A total of 124 speech-language pathologists practising in Australia, working with paediatric and/or adult clients with speech sound difficulties, completed an online survey. The majority of speech-language pathologists reported that they did not use non-speech oral motor exercises when working with paediatric or adult clients with speech sound difficulties. However, more than half of the speech-language pathologists working with adult clients who have dysarthria reported using non-speech oral motor exercises with this population. The most frequently reported rationale for using non-speech oral motor exercises in speech sound difficulty management was to improve awareness/placement of articulators. The majority of speech-language pathologists agreed there is no clear clinical or research evidence base to support non-speech oral motor exercise use with clients who have speech sound difficulties. This study provides an overview of Australian speech-language pathologists' reported use and perceptions of non-speech oral motor exercises' applicability and efficacy in treating paediatric and adult clients who have speech sound difficulties. The research findings provide speech-language pathologists with insight into how and why non-speech oral motor exercises are currently used, and adds to the knowledge base regarding Australian speech-language pathology practice of non-speech oral motor exercises in the treatment of speech sound difficulties. Implications for Rehabilitation Non-speech oral motor exercises refer to oral motor activities which do not involve speech, but involve the manipulation or stimulation of oral structures including the lips, tongue, jaw, and soft palate. Non-speech oral motor exercises are intended to improve the function (e.g., movement, strength) of oral structures. The majority of speech-language pathologists agreed there is no clear clinical or research evidence base to support non-speech oral motor exercise use with clients who have speech sound disorders. Non-speech oral motor exercise use was most frequently reported in the treatment of dysarthria. Non-speech oral motor exercise use when targeting speech sound disorders is not widely endorsed in the literature.

Previously, we reported how to obtain complete autologous oral mucosa equivalents (CAOMEs) composed of an autologous plasma scaffold and fibroblasts together with immature keratinocytes able to build an oral epithelium with a structure similar to that of the oral mucosa. In this study, we present the clinical outcomes after applying our CAOMEs as grafts. Four patients who needed a CAOME to restore a defect of oral mucosa were selected. Two of the patients suffered from ankyloglossia, and the other 2 required a restoration of the keratinized gum of the alveolar rim. To assess the outcomes, the scale designed by Ewers et al. was used. Clinical and functional improvements were achieved in the patients with ankyloglossia. In cases of gum restoration, the mucosa was regenerated and a prosthetic restoration with implants was achieved. The results obtained points to the potential use of CAOME in intraoral lining.

The treatment of patients with oral cancer is complex: a multidisciplinary approach needs to be taken and maxillofacial and oral surgeons, an oncologist, a prosthodontist should be included, and a psychologist is often needed. This case report describes the prosthetic rehabilitation of a patient after surgical removal of oral cancer with obturator prosthesis. Resection cavity was located in central part of the hard palate and the condition belonged to Aramany class 3 maxillary defects. The two-step impression technique of denture bearing area was used and the resection of cavity was performed. A primary impression-the impression of denture bearing area was made using irreversible hydrocolloid material, while the second impression – the impression of resection cavity was made using condensation silicone material and obturator prosthesis framework. The obturator prosthesis replaced lost teeth, improved oral function and esthetics at minimal costs. PMID:27847400

Improving oral bioavailability of cyclic peptides by N-methylation.

Räder, Andreas F B; Reichart, Florian; Weinmüller, Michael; Kessler, Horst

2018-06-01

The renaissance of peptides in pharmaceutical industry results from their importance in many biological functions. However, low metabolic stability and the lack of oral availability of most peptides is a certain limitation. Whereas metabolic instability may be often overcome by development of small cyclic peptides containing d-amino acids, the very low oral availability of most peptides is a serious limitation for some medicinal applications. The situation is complicated because a twofold optimization - biological activity and oral availability - is required to overcome this problem. Moreover, most simple "rules" for achieving oral availability are not general and are applicable only to limited cases. Many structural modifications for increasing biological activities and metabolic stabilities of cyclic peptides have been described, of which N-alkylation is probably the most common. This mini-review focuses on the effects of N-methylation of cyclic peptides in strategies to optimize bioavailabilities. Copyright © 2017 The Authors. Published by Elsevier Ltd..

The aim of this longitudinal observational study was to evaluate the oral health-related quality of life (OHRQoL) following patient rehabilitation with implant-retained mandibular overdentures (IMO) and to identify the contribution of the different domains to OHRQoL. The Oral Health Impact Profile (OHIP-EDENT), Dental Impact on Daily Living (DIDL), and Geriatric Oral Health Assessment Index (GOHAI) questionnaires were completed twice by 25 patients: after 3 months of rehabilitation with complete dentures (CD) and after 3 months of IMO loading using stud abutments. The evaluation after IMO rehabilitation showed significant improvement in three DIDL domains: appearance (p = 0.011), eating and chewing (p = 0.003), and general performance (p = 0.003). The GOHAI results showed significant differences in two domains: psychosocial (p = 0.005) and pain and discomfort (p = 0.0004). The OHIP-EDENT outcomes showed significant improvements in five domains: functional limitation (p = 0.0001), physical pain (p = 0.0002), physical disability (p = 0.0010), and psychological disability and handicap (p = 0.032). The largest observed effect sizes were close to one standard deviation and were observed in the eating and chewing domain (0.93) of the DIDL; the pain and discomfort domain (0.83) of the GOHAI, and the functional limitation (0.89), physical pain (1.02), physical disability (0.84) domains of the OHIP-EDENT. The percentage of satisfied patients increased in all domains. Self-reported OHRQoL of CD wearers was significantly improved after 3 months of treatment with IMO, especially concerning the functional and pain-related aspects.

Possible benefits of singing to the mental and physical condition of the elderly

2014-01-01

Background The evaluation and management of stress are important for the prevention of both depression and cardiovascular disease. In addition, the maintenance of the oral condition of the elderly is essential to enable them to stay healthy, especially to prevent aspiration pneumonia and improve mental health in an aging society. Therefore, we examined the efficacy of singing on the oral condition, mental health status, and immunity of the elderly to determine if singing could contribute to the improvement of their physical condition. Methods Forty-four subjects (10 men, 34 women), aged 60 years or older, participated in this study. The efficacy of singing on mental health status and immunocompetence was examined by swallowing function, oral condition, blood, and saliva tests, as well as through questionnaires taken before and after singing. Results The results showed that the amount of saliva increased and the level of cortisol, a salivary stress marker, decreased after singing. The Visual Analog Scale (VAS) scores for feeling refreshed, comfortable, pleasurable, light-hearted, relieved, and relaxed; the tension and confusion subscale score; and the total mood disturbance (TMD) score of the Profile of Mood States (POMS) all showed improvements. Furthermore, the same tendencies were shown regardless of whether or not the subjects liked singing. Conclusions Our results suggest that singing can be effective in improving the mental health and oral condition of the elderly. PMID:24864162

To study the impact of orthodontic treatment on the quality of life in two patient groups, one treated with the twin block appliance and the other with fixed appliances. Ninety-eight patients, aged between 10 and 16 years, were recruited in the fixed (20 males and 29 females) or functional (29 males and 20 females) treatment groups. The oral health-related quality of life (OHRQoL) was measured before treatment and followed up at the end of the treatment. The instrument used to measure OHRQoL was a modified self-administered short version of the English Oral Health Impact profile (OHIP-16[E]) questionnaire. OHRQoL worsened at the initial stages of the treatment. The overall score of OHRQoL reduced significantly at the end of the treatment in both groups. Both groups showed comparable improvements in OHRQoL as the treatment progressed (analysis of variance test P = 0.05). The OHRQoL patterns, during the treatment with fixed and twin block appliances, were very similar. This suggests that the functional appliance's impact on the QoL may be overestimates by clinicians. OHRQoL improved significantly with both fixed and functional appliances by the end of the treatment. The OHRQoL trends observed during the study can be communicated to patients and used to increase patients' compliance since they are made aware of the whole treatment process.

In the present study thiol functionalized polymethacrylic acid-polyethylene glycol-chitosan (PCP)-based hydrogel microparticles were utilized to develop an oral insulin delivery system. Thiol modification was achieved by grafting cysteine to the activated surface carboxyl groups of PCP hydrogels (Cys-PCP). Swelling and insulin loading/release experiments were conducted on these particles. The ability of these particles to inhibit protease enzymes was evaluated under in vitro experimental conditions. Insulin transport experiments were performed on Caco-2 cell monolayers and excised intestinal tissue with an Ussing chamber set-up. Finally, the efficacy of insulin-loaded particles in reducing the blood glucose level in streptozotocin-induced diabetic rats was investigated. Thiolated hydrogel microparticles showed less swelling and had a lower insulin encapsulation efficiency as compared with unmodified PCP particles. PCP and Cys-PCP microparticles were able to inhibit protease enzymes under in vitro conditions. Thiolation was an effective strategy to improve insulin absorption across Caco-2 cell monolayers, however, the effect was reduced in the experiments using excised rat intestinal tissue. Nevertheless, functionalized microparticles were more effective in eliciting a pharmacological response in diabetic animal, as compared with unmodified PCP microparticles. From these studies thiolation of hydrogel microparticles seems to be a promising approach to improve oral delivery of proteins/peptides. Copyright 2010 Acta Materialia Inc. Published by Elsevier Ltd.

Targeting intestinal di- and tri-peptide transporter PepT1 with prodrugs is a successful strategy to improve oral drug bioavailability, as demonstrated with valacyclovir, a prodrug of acyclovir. The aim of this new drug delivery strategy is to over-concentrate a poorly absorbed drug on the intestinal membrane surface by targeting PepT1 with functionalized polymer nanoparticles. In the present study, poly(lactic acid)-poly(ethylene glycol)-ligand (PLA-PEG-ligand) nanoparticles were obtained by nanoprecipitation. A factorial experimental design allowed us to identify size-influent parameters and to obtain optimized ≈30nm nanoparticles. Valine, Glycylsarcosine, Valine-Glycine, and Tyrosine-Valine were chemically linked to PLA-PEG. In Caco-2 cell monolayer model, competition between functionalized nanoparticles and [ 3 H]Glycylsarcosine, a strong substrate of PepT1, reduced [ 3 H]Glycylsarcosine transport from 22 to 46%. Acyclovir was encapsulated with a drug load of ≈10% in valine-functionalized nanoparticles, resulting in a 2.7-fold increase in permeability as compared to the free drug. An in vivo pharmacokinetic study in mice compared oral absorption of acyclovir after administration of 25mg/kg of valacyclovir, free or encapsulated acyclovir in functionalized nanoparticles. Acyclovir encapsulation did not statistically modify AUC or C max , but increased t 1/2 and MRT 1.3-fold as compared to free acyclovir. This new strategy is promising for poorly absorbed drugs by oral administration. Copyright © 2017 Elsevier B.V. All rights reserved.

Cerebral palsy (CP) is a group of permanent sensorimotor impairments. Children with CP have various feeding difficulties including chewing disorder, which may affect their nutritional status. Functional Chewing Training (FuCT) was designed as a holistic approach to improve chewing function by providing postural alignment, sensory and motor training, and food and environmental adjustments. This study aimed to investigate the effect of FuCT on chewing function in children with CP. This study was designed as a double-blind, randomised controlled trial. Eighty CP children with chewing disorder were randomised and split between the FuCT group (31 males, 19 females; mean age 3·5 ± 1·9 years) and the control group (16 males, 14 females; 3·4 ± 2·3 years) receiving traditional oral motor exercises. Each group received the training programme for 12 weeks with weekly follow-up and with two evaluations at baseline and end of 12 weeks. Chewing function was evaluated by analysing video recordings and scored with the Karaduman Chewing Performance Scale (KCPS). The Behavioral Pediatrics Feeding Assessment Scale (BPFAS) was used to evaluate feeding behaviours of children. A significant improvement was observed in KCPS scores at 12 weeks after training in the FuCT group (P < 0·001), but no change was found in the control group (P = 0·07). A significant improvement was detected in all parameters of BPFAS at 12 weeks after training in the FuCT group (P < 0·001) and in four parameters of BPFAS in the control group (P = 0·02, P = 0·02). FuCT is an effective method to improve chewing function compared with traditional oral motor exercises. © 2016 John Wiley & Sons Ltd.

Thai Massage, and Thai Herbal Compress versus Oral Ibuprofen in Symptomatic Treatment of Osteoarthritis of the Knee: A Randomized Controlled Trial

PubMed Central

2014-01-01

The aim of this study was to verify the clinical responses to Thai massage (TM) and Thai herbal compression (THC) for treating osteoarthritis (OA) of the knee in comparison to oral ibuprofen. This study was a randomized, evaluator-blind, controlled trial. Sixty patients with OA of the knee were randomly assigned to receive either a one-hour session of TM or THC (three times weekly) or oral ibuprofen (three times daily). The duration of treatment was three weeks. The clinical assessments included visual analog scale assessing pain and stiffness, Lequesne's functional index, time for climbing up ten steps, and physician's and patient's overall opinions on improvement. In a within-group comparison, each treatment modality caused a significant improvement of all variables determined for outcome assessments. In an among group comparison, all modalities provided nearly comparable clinical efficacy after a three-week symptomatic treatment of OA of the knee, in which a trend toward greatest improvement was likely to be found in THC group. In conclusion, TM and THC generally provided comparable clinical efficacy to oral ibuprofen after three weeks of treatment and could be considered as complementary and alternative treatments for OA of the knee.

Recording reliable oral health data is a challenge. The aims were a) to outline different Scandinavian systems of oral health monitoring, b) to evaluate the quality and utility of the collected data in the light of modern concepts of disease management and to suggest improvements. The information for in this study was related to (a) children and adolescents, (b) oral health data and (c) routines for monitoring such data. This meant information available in the official web sites of the "KOSTRA-data" (Municipality-State-Report) in Norway, the Swedish National Board of Health and Welfare ("Socialstyrelsen") and Oral Health Register (the SCOR system, National Board of Health) in Denmark. A potential for increasing the reliability and validity of the data existed. Routines for monitoring other oral diseases than caries were limited. Compared with the other Scandinavian countries, the data collection system in Denmark appeared more functional and had adopted more modern concepts of disease management than other systems. In the light of modern concepts of caries management, data collected elsewhere had limited utility. The Scandinavian systems of health reporting had much in common, but some essential differences existed. If the quality of epidemiological data were enhanced, it would be possible to use the data for planning oral health care. Routines and procedures should be improved and updated in accordance with the modern ideas about caries prevention and therapy. For appropriate oral health planning in an organised dental service, reporting of enamel caries is essential.

The stimulation of sensory neurons in the gastrointestinal (GI) tract improves cognitive function by increasing the hippocampal production of insulin-like growth factor-I (IGF-I) in mice. In the current study, we examined whether oral administration of desalted deep-sea water (DSW) increases the hippocampal production of IGF-I by stimulating sensory neurons in the GI tract, thereby improving cognitive function in mice. Desalted DSW increased calcitonin gene-related peptide (CGRP) release from dorsal root ganglion (DRG) neurons isolated from wild-type (WT) mice by activating transient receptor potential vanilloid 1. The plasma levels of IGF-I and tissue levels of CGRP, IGF-I, and IGF-I mRNA in the hippocampus were increased by oral administration of desalted DSW in WT mice. In these animals, nociceptive information originating from the GI tract was transmitted to the hippocampus via the spinothalamic pathway. Improvement of spatial learning was observed in WT mice after administration of desalted DSW. Distilled DSW showed results similar to those of desalted DSW in vitro and in vivo. None of the effects of desalted DSW in WT mice were observed after the administration of desalted DSW in CGRP-knockout (CGRP-/-) mice. No volatile compounds were detected in distilled DSW on GC-MS analysis. These observations suggest that desalted DSW may increase the hippocampal IGF-I production via sensory neuron stimulation in the Gl tract, thereby improving cognitive function in mice. Such effects of desalted DSW might not be dependent on the minerals but are dependent on the function of the water molecule itself. Copyright © 2011 Mosby, Inc. All rights reserved.

Malnutrition is a common problem in patients with digestive disease and is associated with impaired outcome. We investigated the effect of a three-month post-hospital nutritional intervention with high protein and energy supplements on body composition, muscle function and quality of life (QoL) in malnourished GI patients. Eighty malnourished patients with benign digestive disease were randomized to receive either oral nutritional supplements (ONS) for three months in addition to dietary counselling (DC) (ONS patients) or only dietary counselling (DC patients). Nutritional status was determined with the subjective global assessment, body composition by bioelectrical impedance and anthropometry, muscle function with hand-grip strength and peak flow. QoL was assessed by the 36-item short-form questionnaire. Age, body cell mass (BCM), muscle function, gender distribution and QoL did not differ between ONS patients (n=38) and DC patients (n=42) at baseline. Body weight and BCM improved significantly in both groups after three months. However, hand-grip strength (26.1+/-11.3-31.5+/-10.1 kg, p<0.0001) and peak flow (329.2+/-124.0-388.9+/-108.4 l /min, p=0.004) improved only in the ONS patients and remained unchanged in the DC patients. Similarly, all eight scales of the QoL improved in the ONS patients compared with merely three in the DC patients. DC patients experienced significantly more readmissions (n=20) than ONS patients (n=10) during the study period (p=0.041). A three month intervention with high protein oral supplements improves outcome in malnourished patients with digestive disease in terms of functional status, QoL and rehospitalization.

In recent years, advances in biotechnology and protein engineering have enabled the production of large quantities of proteins and peptides as important therapeutic agents. Various researchers have used biocompatible functional polymers to prepare oral dosage forms of proteins and peptides for chronic use and for easier administration to enhance patient compliance. However, there is a need to enhance their safety and effectiveness further. Most macromolecules undergo severe denaturation at low pH and enzymatic degradation in the gastrointestinal tract. The macromolecules' large molecular size and low lipophilicity cause low permeation through the intestinal membrane. The major strategies that have been used to overcome these challenges (in oral drug carrier systems) can be classified as follows: enteric coating or encapsulation with pH-sensitive polymers or mucoadhesive polymers, co-administration of protease inhibitors, incorporation of absorption enhancers, modification of the physicochemical properties of the macromolecules, and site-specific delivery to the colon. This review attempts to summarize the various advanced oral delivery carriers, including nanoparticles, lipid carriers, such as liposomes, nano-aggregates using amphiphilic polymers, complex coacervation of oppositely charged polyelectrolytes, and inorganic porous particles. The particles were formulated and/or surface modified with functional polysaccharides or synthetic polymers to improve oral bioavailability of proteins and peptides. We also discuss formulation strategies to overcome barriers, therapeutic efficacies in vivo, and potential benefits and issues for successful oral dosage forms of the proteins and peptides.

This study aimed to assess: (1) oral symptoms of patients treated for oral or oropharyngeal cancer; (2) how patients rank the burden of oral symptoms; (3) the impact of the tumor, the treatment, and oral symptoms on functional outcome. Eighty-nine patients treated for oral or oropharyngeal cancer were asked about their oral symptoms related to mouth opening, dental status, oral sensory function, tongue mobility, salivary function, and pain. They were asked to rank these oral symptoms according to the degree of burden experienced. The Mandibular Function Impairment Questionnaire (MFIQ) was used to assess functional outcome. In a multivariate linear regression analyses, variables related to MFIQ scores (p≤0.10) were entered as predictors with MFIQ score as the outcome. Lack of saliva (52%), restricted mouth opening (48%), and restricted tongue mobility (46%) were the most frequently reported oral symptoms. Lack of saliva was most frequently (32%) ranked as the most burdensome oral symptom. For radiated patients, an inability to wear a dental prosthesis, a T3 or T4 stage, and a higher age were predictive of MFIQ scores. For non-radiated patients, a restricted mouth opening, an inability to wear a dental prosthesis, restricted tongue mobility, and surgery of the mandible were predictive of MFIQ scores. Lack of saliva was not only the most frequently reported oral symptom after treatment for oral or oropharyngeal cancer, but also the most burdensome. Functional outcome is strongly influenced by an inability to wear a dental prosthesis in both radiated and non-radiated patients.

Purpose Multi-modality therapy has resulted in improved survival for childhood malignancies. The Children’s Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancers provide practitioners with exposure- and risk-based recommendations for the surveillance and management of asymptomatic survivors who are at least 2 years from completion of therapy. This review outlines the pathophysiology and risks for oral and dental late effects in pediatric cancer survivors and the rationale for oral and dental screening recommended by the Children’s Oncology Group. Methods An English literature search for oral and dental complications of childhood cancer treatment was undertaken via MEDLINE and encompassed January 1975 to January 2013. Proposed guideline content based on the literature review was approved by a multi-disciplinary panel of survivorship experts and scored according to a modified version of the National Comprehensive Cancer Network “Categories of Consensus” system. Results The Children’s Oncology Group oral-dental pan el selected 85 relevant citations. Childhood cancer therapy may impact tooth development, salivary function, craniofacial development, and temporomandibular joint function placing some childhood cancer survivors at an increased risk for poor oral and dental health. Addition ally, head and neck radiation and hematopoietic stem cell transplantation increase the risk of subsequent ma lignant neoplasms in the oral cavity. Survivors require routine dental care to evaluate for potential side effects and initiate early treatment. Conclusions Certain childhood cancer survivors are at an increased risk for poor oral and dental health. Early identification of oral and dental morbidity and early interventions can optimize health and quality of life. PMID:24781353

No studies have tested oral health-related quality of life models in dentate older adults across different populations. To test the factor structure of oral health outcomes within Gilbert's conceptual model among 65-year olds in Sweden and Norway. It was hypothesized that responses to 14 observed indicators could be explained by three correlated factors, symptom status, functional limitations and oral disadvantages, that each observed oral health indicator would associate more strongly with the factor it is supposed to measure than with competing factors and that the proposed 3-factor structure would possess satisfactory cross-national stability with 65-year olds in Norway and Sweden. In 2007, 6078 Swedish- and 4062 Norwegian adults borne in 1942 completed mailed questionnaires including oral symptoms, functional limitations and the eight item Oral Impacts on Daily Performances inventory. Model generation analysis was restricted to the Norwegian study group and the model achieved was tested without modifications in Swedish 65-year olds. A modified 3-factor solution with cross-loadings, improved the fit to the data compared with a 2-factor- and the initially proposed 3-factor model among the Norwegian [comparative fit index (CFI) = 0.97] and Swedish (CFI = 0.98) participants. All factor loadings for the modified 3-factor model were in the expected direction and were statistically significant at CR > 1. Multiple group confirmatory factor analyses, with Norwegian and Swedish data simultaneously revealed acceptable fit for the unconstrained model (CFI = 0.97), whereas unconstrained and constrained models were statistically significant different in nested model comparison. Within construct validity of Gilbert's model was supported with Norwegian and Swedish 65-year olds, indicating that the 14-item questionnaire reflected three constructs; symptom status, functional limitation and oral disadvantage. Measurement invariance was confirmed at the level of factor structure, suggesting that the 3-factor model is comparable to some extent across 65-year olds in Norway and Sweden.

The electronic Schizophrenia Treatment Adherence Registry (e-STAR) is a prospective, observational study of patients with schizophrenia designed to evaluate long-term treatment outcomes in routine clinical practice. Parameters were assessed at baseline and at 3 month intervals for 2 years in patients initiated on risperidone long-acting injection (RLAI) (n=1345) or a new oral antipsychotic (AP) (n=277; 35.7% and 36.5% on risperidone and olanzapine, respectively) in Spain. Hospitalization prior to therapy was assessed by a retrospective chart review. At 24 months, treatment retention (81.8% for RLAI versus 63.4% for oral APs, p<0.0001) and reduction in Clinical Global Impression Severity scores (-1.14 for RLAI versus -0.94 for APs, p=0.0165) were significantly higher with RLAI. Compared to the pre-switch period, RLAI patients had greater reductions in the number (reduction of 0.37 stays per patient versus 0.2, p<0.05) and days (18.74 versus 13.02, p<0.01) of hospitalizations at 24 months than oral AP patients. This 2 year, prospective, observational study showed that, compared to oral antipsychotics, RLAI was associated with better treatment retention, greater improvement in clinical symptoms and functioning, and greater reduction in hospital stays and days in hospital in patients with schizophrenia. Improved treatment adherence, increased efficacy and reduced hospitalization with RLAI offer the opportunity of substantial therapeutic improvement in schizophrenia.

Peripheral paralysis of the facial nerve is the most frequent of all cranial nerve disorders. Despite advances in facial surgery, the functional and aesthetic reconstruction of a paralyzed face remains a challenge. Graduated minimally invasive facial reanimation is based on a modular principle. According to the patients' needs, precondition, and expectations, the following modules can be performed: temporalis muscle transposition and facelift, nasal valve suspension, endoscopic brow lift, and eyelid reconstruction. Applying a concept of a graduated minimally invasive facial reanimation may help minimize surgical trauma and reduce morbidity. Twenty patients underwent a graduated minimally invasive facial reanimation. A retrospective chart review was performed with a follow-up examination between 1 and 8 months after surgery. The FACEgram software was used to calculate pre- and postoperative eyelid closure, the level of brows, nasal, and philtral symmetry as well as oral commissure position at rest and oral commissure excursion with smile. As a patient-oriented outcome parameter, the Glasgow Benefit Inventory questionnaire was applied. There was a statistically significant improvement in the postoperative score of eyelid closure, brow asymmetry, nasal asymmetry, philtral asymmetry as well as oral commissure symmetry at rest (p < 0.05). Smile evaluation revealed no significant change of oral commissure excursion. The mean Glasgow Benefit Inventory score indicated substantial improvement in patients' overall quality of life. If a primary facial nerve repair or microneurovascular tissue transfer cannot be applied, graduated minimally invasive facial reanimation is a promising option to restore facial function and symmetry at rest.

Challenges to improvement of oral health in the 21st century--the approach of the WHO Global Oral Health Programme.

Chronic diseases and injuries are overtaking communicable diseases as the leading health problems in all but a few parts of the world. This rapidly changing global disease pattern is closely linked to changing lifestyles, which include diets rich in sugars, widespread use of tobacco and increased consumption of alcohol. These lifestyle factors also significantly impact on oral health, and oral diseases qualify as major public health problems owing to their high prevalence and incidence in all regions of the world. Like all diseases, they affect primarily the disadvantaged and socially marginalised populations, causing severe pain and suffering, impairing function and impacting on quality of life. Traditional treatment of oral diseases is extremely costly even in industrialised countries and is unaffordable in most low and middle-income countries. The WHO global strategy for prevention and control of noncommunicable diseases and the 'common risk factor approach' offer new ways of managing the prevention and control of oral diseases. This document outlines the current oral health situation and development trends at global level as well as WHO strategies and approaches for better oral health in the 21 st century.

Antibiotics are commonly used in the management of respiratory disorders such as cystic fibrosis (CF), non-CF bronchiectasis, asthma and COPD. In those conditions long-term antibiotics can be delivered as nebulised aerosols or administered orally. In CF, nebulised colomycin or tobramycin improve lung function, reduce number of exacerbations and improve quality of life (QoL). Oral antibiotics, such as macrolides, have acquired wide use not only as anti-microbial agents but also due to their anti-inflammatory and pro-kinetic properties. In CF, macrolides such as azithromycin have been shown to improve the lung function and reduce frequency of infective exacerbations. Similarly macrolides have been shown to have some benefits in COPD including reduction in a number of exacerbations. In asthma, macrolides have been reported to improve some subjective parameters, bronchial hyperresponsiveness and airway inflammation; however have no benefits on lung function or overall asthma control. Macrolides have also been used with beneficial effects in less common disorders such as diffuse panbronchiolitis or post-transplant bronchiolitis obliterans syndrome. In this review we describe our current knowledge the use of long-term antibiotics in conditions such as CF, non-CF bronchiectasis, asthma and COPD together with up-to-date clinical and scientific evidence to support our understanding of the use of antibiotics in those conditions.

Transarterial chemoembolization (TACE) is usually followed by hepatic dysfunction. We evaluated the effects of L-carnitine on post-TACE impaired liver functions. Methods. 53 cirrhotic hepatocellular carcinoma patients at Osaka Medical College were enrolled in this study and assigned into either L-carnitine group receiving 600 mg oral L-carnitine daily or control group. Liver functions were evaluated at pre-TACE and 1, 4, and 12 weeks after TACE. Results. The L-carnitine group maintained Child-Pugh (CP) score at 1 week after TACE and exhibited significant improvement at 4 weeks after TACE (P < 0.01). Conversely, the control group reported a significant CP score deterioration at 1 week (P < 0.05) and 12 weeks after TACE (P < 0.05). L-carnitine suppressed serum albumin deterioration at 1 week after TACE. There were significant differences between L-carnitine and control groups regarding mean serum albumin changes from baseline to 1 week (P < 0.05) and 4 weeks after TACE (P < 0.05). L-carnitine caused prothrombin time improvement from baseline to 1, 4 (P < 0.05), and 12 weeks after TACE. Total bilirubin mean changes from baseline to 1 week after TACE exhibited significant differences between L-carnitine and control groups (P < 0.05). The hepatoprotective effects of L-carnitine were enhanced by branched chain amino acids combination. Conclusion. L-carnitine maintained and improved liver functions after TACE.

Clearance of fibrin and associated inflammatory cytokines by tissue-type plasminogen activator (t-PA) is related to improved regeneration in neurological disorder. The biological activity of fermented soybean (natto) is very similar to that of t-PA. We investigated the effect of the dietary supplement of natto on peripheral nerve regeneration. The peripheral nerve injury was produced by crushing the left sciatic nerve with a vessel clamp in Sprague-Dawley rats. The injured animals were fed orally either with saline or natto (16 mg/day) for seven consecutive days after injury. Increased functional outcome such as sciatic nerve functional index, angle of ankle, compound muscle action potential and conduction latency were observed in natto-treated group. Histological examination demonstrated that natto treatment improved injury-induced vacuole formation, S-100 and vessel immunoreactivities and axon loss. Oral intake of natto prolonged prothrombin time and reduced fibrinogen but did not change activated partial thromboplastin time and bleeding time. Furthermore, natto decreased injury-induced fibrin deposition, indicating a tolerant fibrinolytic activity. The treatment of natto significantly improved injury-induced disruption of blood-nerve barrier and loss of matrix component such as laminin and fibronectin. Sciatic nerve crush injury induced elevation of tumor necrosis factor alpha (TNF-alpha) production and caused apoptosis. The increased production of TNF-alpha and apoptosis were attenuated by natto treatment. These findings indicate that oral intake of natto has the potential to augment regeneration in peripheral nerve injury, possibly mediated by the clearance of fibrin and decreased production of TNF-alpha.

Dysphagia is relatively common in individuals with neurological disorders. To describe the swallowing management and investigate associated factors with swallowing in a case series of patients with Parkinson's disease. It is a long-term study with 24 patients. The patients were observed in a five-year period (2006-2011). They underwent Fiberoptic Endoscopic Evaluation of Swallowing, Functional Oral Intake Scale and therapeutic intervention every three months. In the therapeutic intervention they received orientation about exercises to improve swallowing. The Chi-square, Kruskal-Wallis and Fisher's tests were used. The period of time for improvement or worsening of swallowing was described by Kaplan-Meier analysis. During the follow-up, ten patients improved, five stayed the same and nine worsened their swallowing functionality. The median time for improvement was ten months. Prior to the worsening there was a median time of 33 months of follow-up. There was no associated factor with improvement or worsening of swallowing. The maneuvers frequently indicated in therapeutic intervention were: chin-tuck, bolus consistency, bolus effect, strengthening-tongue, multiple swallows and vocal exercises. The swallowing management was characterized by swallowing assessment every three months with indication of compensatory and rehabilitation maneuvers, aiming to maintain the oral feeding without risks. There was no associated factor with swallowing functionality in this case series. Copyright © 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Long-acting injectable antipsychotics may offer a relevant improvement in treatment adherence in recent-onset psychosis, leading to a decreased rate of hospital readmission, a better rate of clinical remission and improved psychosocial adjustment. The aim of the study was to compare the clinical remission rates, number of hospital readmissions and personal and social functioning after 2 years between patients with recent-onset schizophrenia (<2 years) in treatment with risperidone long-acting injectable (RLAI) and patients with recent-onset schizophrenia receiving oral antipsychotics. This is a case-control study comparing patients with recent-onset schizophrenia who initiated RLAI treatment between 2004 and 2008 (n=26) with a control group matched for age and sex, diagnosed with recent-onset schizophrenia and treated with oral antipsychotics (n=26). Study assessments included sociodemographic variables, the Positive and Negative Syndrome Scale, the Personal and Social Functioning Scale, the number of hospital readmissions and the Andreasen remission criteria. To assess the effect of treatment on each dependent variable, separate generalized estimating equations models were constructed. After 2 years of treatment, and adjusting for educational level, the RLAI group showed a greater reduction in the Positive and Negative Syndrome Scale total scale [mean (SD)=47.7 (12.0) vs. 66.2 (18.5); mean difference =-17.56; 95% confidence interval (CI)=-27.11 to -8.00; P<0.001], as well as in the negative [mean (SD) 14.3 (6.1) vs. 19.4 (6.4); mean difference=-5.02; 95% CI=-8.28 to -1.77; P=0.002] and general psychopathology [mean (SD)=23.4 (6.3) vs. 32.7 (8.1); mean difference=-9.16; 95% CI=-13.3 to -5.03; P<0.001] subscales compared with the oral antipsychotic group. Personal and Social Functioning Scale scores were also higher in the RLAI group [mean (SD)=72.4 (14.8) vs. 59.7 (13.5); mean difference=13.41; 95% CI=5.65-21.18; P<0.001]. Although not statistically significant, there were fewer readmissions (adjusted odds ratio 0.28; 95% CI=0.06-1.35; P=0.114) and more illness remissions (adjusted odds ratio 3.24; 95% CI=0.20-11.93; P=0.077) in the RLAI group. Treatment with RLAI instead of oral antipsychotics in recent-onset schizophrenia might improve clinical symptoms and social functioning. The efficacy of RLAI treatment on remission and readmission rates should be researched further.

Phosphodiesterase inhibitors such as milrinone can relieve symptoms and improve hemodynamics in patients with advanced congestive heart failure. We retrospectively evaluated the hemodynamic and clinical outcomes of long-term combination therapy with intravenous milrinone and oral β-blockers in 65 patients with severe congestive heart failure (New York Heart Association class IV function and ejection fraction <25%) refractory to oral medical therapy. Fifty-one patients successfully began β-blocker therapy while on intravenous milrinone. Oral medical therapy was maximized when possible. The mean duration of milrinone treatment in this combination-treatment group was 269 days (range, 14–1,026 days). Functional class improved from IV to II–III with milrinone therapy. Twenty-four such patients tolerated β-blocker up-titration and were successfully weaned from milrinone. Sixteen patients (31%) died while receiving combination therapy; one died of sudden cardiac death (on treatment day 116); the other 15 died of progressive heart failure or other complications. Hospital admissions during the previous 6 months and admissions within 6 months after milrinone initiation stayed the same. Meanwhile, the total number of hospital days decreased from 450 to 380 (a 15.6% reduction), and the mean length of stay decreased by 1.4 days (a 14.7% reduction). We conclude that 1) milrinone plus β-blocker combination therapy is an effective treatment for heart failure even with β-blocker up-titration, 2) weaning from milrinone may be possible once medications are maximized, 3) patients' functional status improves on the combination regimen, and 4) treatment-related sudden death is relatively infrequent during the combination regimen.

Context: Hesperidin, a citrus flavonoid, and its metabolite hesperetin may have vascular actions relevant to their health benefits. Molecular and physiological mechanisms of hesperetin actions are unknown. Objective: We tested whether hesperetin stimulates production of nitric oxide (NO) from vascular endothelium and evaluated endothelial function in subjects with metabolic syndrome on oral hesperidin therapy. Design, Setting, and Interventions: Cellular mechanisms of action of hesperetin were evaluated in bovine aortic endothelial cells (BAEC) in primary culture. A randomized, placebo-controlled, double-blind, crossover trial examined whether oral hesperidin administration (500 mg once daily for 3 wk) improves endothelial function in individuals with metabolic syndrome (n = 24). Main Outcome Measure: We measured the difference in brachial artery flow-mediated dilation between placebo and hesperidin treatment periods. Results: Treatment of BAEC with hesperetin acutely stimulated phosphorylation of Src, Akt, AMP kinase, and endothelial NO synthase to produce NO; this required generation of H2O2. Increased adhesion of monocytes to BAEC and expression of vascular cell adhesion molecule-1 in response to TNF-α treatment was reduced by pretreatment with hesperetin. In the clinical study, when compared with placebo, hesperidin treatment increased flow-mediated dilation (10.26 ± 1.19 vs. 7.78 ± 0.76%; P = 0.02) and reduced concentrations of circulating inflammatory biomarkers (high-sensitivity C-reactive protein, serum amyloid A protein, soluble E-selectin). Conclusions: Novel mechanisms for hesperetin action in endothelial cells inform effects of oral hesperidin treatment to improve endothelial dysfunction and reduce circulating markers of inflammation in our exploratory clinical trial. Hesperetin has vasculoprotective actions that may explain beneficial cardiovascular effects of citrus consumption. PMID:21346065

Over the last two decades, progress in prevention and treatment of caries and periodontal diseases has been translated to better oral health and improved tooth retention in the adult population. The ageing population and the increasing expectations of good oral health-related quality of life in older age pose formidable challenges to clinical care and healthcare systems. The objective of this workshop was to critically review scientific evidence and develop specific recommendations to: (i) prevent tooth loss and retain oral function through prevention and treatment of caries and periodontal diseases later in life and (ii) increase awareness of the health benefits of oral health as an essential component of healthy ageing. Discussions were initiated by three systematic reviews covering aspects of epidemiology of caries and periodontal diseases in elders, the impact of senescence on caries and periodontal diseases and the effectiveness of interventions. Recommendations were developed based on evidence from the systematic reviews and expert opinion. Key messages included: (i) the ageing population, trends in risk factors and improved tooth retention point towards an expected increase in the total burden of disease posed by caries and periodontal diseases in the older population; (ii) specific surveillance is required to monitor changes in oral health in the older population; (iii) senescence impacts oral health including periodontitis and possibly caries susceptibility; (iv) evidence indicates that caries and periodontal diseases can be prevented and treated also in older adults; (v) oral health and functional tooth retention later in life provides benefits both in terms of oral and general quality of life and in terms of preventing physical decline and dependency by fostering a healthy diet; (vi) oral healthcare professionals and individuals should not base decisions impacting tooth retention on chronological age but on level of dependency, life expectancy, frailty, comfort and quality of life; and (vii) health policy should remove barriers to oral health care for vulnerable elders. Consensus was reached on specific actionable priorities for public health officials, oral healthcare professionals, educators and workforce planners, caregivers and relatives as well as for the public and ageing patients. Some priorities have major implications for policymakers as health systems need to adapt to the challenge by systemwide changes to enable (promote) tooth retention later in life and management of deteriorating oral health in increasingly dependent elders. © 2017 John Wiley & Sons A/S.

This study aimed to develop an oral delivery system using clay-based organic-inorganic hybrid materials to improve the bioavailability of the drug, flurbiprofen, which is poorly soluble in water. 3-aminopropyl functionalized magnesium phyllosilicate (AMP clay) was synthesized by a one-pot direct sol-gel method, and then flurbiprofen (FB) was incorporated into AMP clay (FB-AMP) at different drug/clay ratios. The structural characteristics of AMP and FB-AMP formulation were confirmed by X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy. Among tested formulations, FB-AMP(3), dramatically increased the dissolution of FB and achieved rapid and complete drug release within 2 hours. More than 60% of FB was released from FB-AMP(3) after 30 minutes; the drug was completely dissolved in the water within 2 hours. Under the acidic condition (pH 1.2), FB-AMP(3) also increased the dissolution of FB by up to 47.1% within 1 hour, which was three-fold higher than that of untreated FB. Furthermore, following an oral administration of FB-AMP(3) to Sprague-Dawley rats, the peak plasma concentration and area under the plasma concentration-time curve of FB increased two-fold, and the time to reach the peak plasma concentration was shortened compared with that in the untreated FB. This result suggests that the oral drug delivery system using clay-based organic-inorganic hybrid material might be useful to improve the bioavailability of FB.

Although oral contraceptives (OCs) are one the most widespread therapy in young polycystic ovary syndrome (PCOS) women and physical exercise represents a crucial first step in the treatment of overweight and obese PCOS, no studies were performed to compare the effects on cardiovascular risk (CVR) of OCs and physical exercise in PCOS. To compare the effects of OCs administration and physical exercise on the CVR, clinical, hormonal and metabolic parameters in PCOS women. One hundred and fifty PCOS women were enrolled and were randomized to OCs (3 mg drospirenone plus 30 μg ethinyloestradiol), structured exercise training programme (SETP) or polyvitamin tablets. The intervention phase study was of 6 months. Primary outcome was intima-media thickness (IMT) and flow-mediated dilation (FMD). Secondary outcomes were clinical, hormonal and metabolic changes. A significant reduction of IMT and a significant increase of FMD were observed in the SETP group after treatment. Compared to baseline, in the SETP group, a significant improvement in anthropometric measures, insulin sensitivity indexes, lipid profile, cardiopulmonary function, inflammatory markers and frequency of menses was observed. Oral contraceptives use was associated with a significant decrease of hyperandrogenism and a significant improvement of frequency of menses. Further, OCs use had a neutral effect on CVR risk factors. OCs effectively treat hyperandrogenism and menstrual disturbances, while SETP is more effective in improving cardiometabolic profile and cardiopulmonary function in PCOS . © 2016 John Wiley & Sons Ltd.

We evaluated the efficacy of a 12-week oral treatment with azithromycin in adult patients with bronchiectasis. The objectives were to demonstrate that this treatment reduces sputum volume, improves quality of life and to assess the lengths of effects after cessation of therapy. Seventy-eight patients with bronchiectasis confirmed by high-resolution computed tomography were included in this study. Subjects received oral azithromycin or placebo in a randomized manner for 12 weeks followed by placebo for another 12 weeks. Sputum volume, St George's Respiratory Questionnaire (SGRQ) score and spirometry were recorded at baseline, 12 weeks and 24 weeks, respectively. End-point measurements were compared from baseline to the end of each study phase. Sixty-eight subjects were included in the analysis. Mean 24-h sputum volume significantly decreased (P < 0.01) during the active treatment phase and remained low during the control phase (P < 0.01). The mean SGRQ total score with azithromycin decreased (i.e. improved health status) from baseline by more than the 4 points at the end of 12 and 24 weeks. Lung functions remained stable during oral azithromycin therapy and the subsequent control phase. Twelve weeks administration of azithromycin in bronchiectasis produces significant reductions in mean sputum volume, health status and stabilization of lung function values. Sputum volume reduction and the improvement of quality of life were sustained for 12 weeks after cessation of azithromycin.

OBJECTIVE: To study the impact of orthodontic treatment on the quality of life in two patient groups, one treated with the twin block appliance and the other with fixed appliances. MATERIALS AND METHODS: Ninety-eight patients, aged between 10 and 16 years, were recruited in the fixed (20 males and 29 females) or functional (29 males and 20 females) treatment groups. The oral health-related quality of life (OHRQoL) was measured before treatment and followed up at the end of the treatment. The instrument used to measure OHRQoL was a modified self-administered short version of the English Oral Health Impact profile (OHIP-16[E]) questionnaire. RESULTS: OHRQoL worsened at the initial stages of the treatment. The overall score of OHRQoL reduced significantly at the end of the treatment in both groups. Both groups showed comparable improvements in OHRQoL as the treatment progressed (analysis of variance test P = 0.05). CONCLUSIONS: The OHRQoL patterns, during the treatment with fixed and twin block appliances, were very similar. This suggests that the functional appliance's impact on the QoL may be overestimates by clinicians. OHRQoL improved significantly with both fixed and functional appliances by the end of the treatment. The OHRQoL trends observed during the study can be communicated to patients and used to increase patients’ compliance since they are made aware of the whole treatment process. PMID:28546959

Butyrate can improve gut functions, whereas histone deacetylase inhibitors might alleviate neurocognitive alterations. Our aim was to assess whether oral butyrate could modulate brain metabolism and plasticity and if this would relate to gut function. Sixteen pigs were subjected to sodium butyrate (SB) supplementation via beverage water or water only [control (C)]. All pigs had blood sampled after 2 and 3 wk of treatment, and were subjected to a brain positron emission tomography after 3 wk. Animals were euthanized after 4 wk to sample pancreas, intestine, and brain for gut physiology and anatomy measurements, as well as hippocampal histology, Ki67, and doublecortin (DCX) immunohistochemistry. SB compared with C treatment triggered basal brain glucose metabolism changes in the nucleus accumbens and hippocampus ( P = 0.003), increased hippocampal granular cell layer volume ( P = 0.006), and neurogenesis (Ki67: P = 0.026; DCX: P = 0.029). After 2 wk of treatment, plasma levels of glucose, insulin, lactate, glucagon-like peptide 1, and peptide tyrosine tyrosine remained unchanged. After 3 wk, plasma levels of lactate were lower in SB compared with C animals ( P = 0.028), with no difference for glucose and insulin. Butyrate intake impacted very little gut anatomy and function. These results demonstrate that oral SB impacted brain functions with little effects on the gut.-Val-Laillet, D., Guérin, S., Coquery, N., Nogret, I., Formal, M., Romé, V., Le Normand, L., Meurice, P., Randuineau, G., Guilloteau, P., Malbert, C.-H., Parnet, P., Lallès, J.-P., Segain, J.-P.

Information and communication technology (ICT) can provide knowledge and clinical support to those working in residential aged care facilities (RACFs). This paper aims to: (1) review literature on ICT targeted at residents, staff and external providers in RACFs including general practitioners, dental and allied health professionals on improving residents' oral health; (2) identify barriers and enablers to using ICT in promoting oral health at RACFs; and (3) investigate evidence of effectiveness of these approaches in promoting oral health. Findings from this narrative literature review indicate that ICT is not widely used in RACFs, with barriers to usage identified as limited training for staff, difficulties accessing the Internet, limited computer literacy particularly in older staff, cost and competing work demands. Residents also faced barriers including impaired cognitive and psychosocial functioning, limited computer literacy and Internet use. Findings suggest that more education and training in ICT to upskill staff and residents is needed to effectively promote oral health through this medium.

Scandinavian systems monitoring the oral health in children and adolescents; an evaluation of their quality and utility in the light of modern perspectives of caries management

Background Recording reliable oral health data is a challenge. The aims were a) to outline different Scandinavian systems of oral health monitoring, b) to evaluate the quality and utility of the collected data in the light of modern concepts of disease management and to suggest improvements. Material and methods The information for in this study was related to (a) children and adolescents, (b) oral health data and (c) routines for monitoring such data. This meant information available in the official web sites of the “KOSTRA-data” (Municipality-State-Report) in Norway, the Swedish National Board of Health and Welfare (“Socialstyrelsen”) and Oral Health Register (the SCOR system, National Board of Health) in Denmark. Results A potential for increasing the reliability and validity of the data existed. Routines for monitoring other oral diseases than caries were limited. Compared with the other Scandinavian countries, the data collection system in Denmark appeared more functional and had adopted more modern concepts of disease management than other systems. In the light of modern concepts of caries management, data collected elsewhere had limited utility. Conclusions The Scandinavian systems of health reporting had much in common, but some essential differences existed. If the quality of epidemiological data were enhanced, it would be possible to use the data for planning oral health care. Routines and procedures should be improved and updated in accordance with the modern ideas about caries prevention and therapy. For appropriate oral health planning in an organised dental service, reporting of enamel caries is essential. PMID:24885243

Ectodermal dysplasia (ED) is an anomaly determined by genetic factors that alter ectodermal structures such as skin, hair, nails, glands, and teeth. Children affected by this condition require extensive, comprehensive, and multidisciplinary treatment. An 8-year-old female patient visited the Dentistry Clinic of the Federal University of Santa Catarina with the chief complaint of multiple missing teeth. The mother reported that the patient had ED. Clinical and radiographic examination revealed the congenital absence of several primary and permanent teeth and tooth germs. Subsequent oral rehabilitation comprised the application of a maxillary denture and mandibular implant-supported fixed prosthesis. The child was also supplied with a wig for further enhancement of esthetics aimed at improving her emotional wellbeing. Psychological follow-up and speech therapy were also provided. After 4 years of follow-up, implant-supported oral rehabilitation has proved to be a satisfactory treatment option, allowing restoration of masticatory, phonetic, and esthetic function, as well as an improvement in the patient's self-esteem and social wellbeing.

The evolution of prostacyclins in pulmonary arterial hypertension: from classical treatment to modern management.

PubMed

Burger, Charles D; D'Albini, Lesley; Raspa, Susan; Pruett, Janis A

2016-01-01

Prostacyclins for the treatment of pulmonary arterial hypertension (PAH) have historically been covered under the insurance medical benefit because they require durable medical equipment and are administered by an intravenous, subcutaneous, or inhalation route. However, more treatment options that target the prostacyclin pathway have become available. As the number and type of options expand, an improved understanding of these drugs will aid managed care decision makers in evaluating new treatment options and making clinically sound and cost-effective treatment decisions. PAH is a progressive disease of pulmonary vascular remodeling that increases pulmonary vascular resistance and often results in right-side heart failure and death if left untreated. Adverse event profiles, the complexity of administration modalities, and potential complications must be considered when administering prostacyclin therapy. Traditional modes of administration, with their potential challenges and complications, may have contributed to the unmet need for an oral agent. Another consideration for managed care decision makers is that oral agents are generally covered under the insurance pharmacy benefit. Access to oral medications with long-term outcomes data, as well as the improved convenience of oral therapy, may help patients with PAH maximize function by maintaining a more convenient and consistent therapeutic regimen.

Opioid treatment interferes with anal sphincter function and its regulation during defecation. This may result in straining, incomplete evacuation, and contribute to opioid-induced bowel dysfunction (OIBD). Employing an experimental model of oxycodone-induced OIBD, we hypothesized that co-administration of the peripherally acting μ-opioid antagonist naloxegol would improve anal sphincter function in comparison to placebo. In a double-blind randomized crossover trial, 24 healthy males were assigned to a six-day treatment of oral oxycodone 15 mg twice daily in combination with either oral naloxegol 25 mg once daily or placebo. At baseline and at day 6, anal resting pressure and the recto-anal inhibitory reflex (RAIR) were evaluated using manometry and rectal balloon distension. Furthermore, the functional lumen imaging probe was used to measure distensibility of the anal canal. Gastrointestinal symptoms were assessed with the Patient Assessment of Constipation Symptom (PAC-SYM) questionnaire and the Bristol Stool Form Scale. During oxycodone treatment, naloxegol improved RAIR-induced sphincter relaxation by 15% (-45.9 vs -38.8 mm Hg; P < 0.01). No differences in anal resting pressure and anal canal distensibility were found between treatments (all P > 0.5). Naloxegol improved PAC-SYM symptoms (mean score over days; 2.6 vs 4.5, P < 0.001) and improved stool consistency scores (mean score over days; 3.3 vs 2.9, P < 0.01). In this experimental model of OIBD, naloxegol improved the RAIR and reduced gastrointestinal symptoms. Hence, in contrast to conventional laxatives, naloxegol may regulate opioid-induced anal sphincter dysfunction and facilitate the defecation process. Copyright © 2018 Elsevier B.V.

Our goal was to determine the impact of reconstructive microsurgery on the treatment of advanced oral cavity cancers. We reviewed 484 patients undergoing resection of T3-4 oral cavity squamous cell cancers from 1980 to 2004. To examine how reconstructive microsurgery affects outcomes, we compared 135 patients treated prior to the introduction of free tissue transfer and 349 patients treated after the introduction of free tissue transfer. Cancers treated after the introduction of free flaps included a significantly higher proportion of T4 compared to T3 lesions and significantly more advanced N classification lesions. Although cancers were more advanced, survival and recurrence rates were maintained and the rate of positive pathologic margins decreased significantly. In addition, fistula and tracheostomy dependence rates decreased and rates of intelligible speech increased. Reconstructive microsurgery contributes to improved oncologic outcomes in addition to better function and lower morbidity in oral cavity cancer treatment. (c) 2009 Wiley Periodicals, Inc.

Oral tactile perception is important for better mastication, appetite, and enjoyment of food. However, previous investigations have not utilized comprehensible variables thought to have negative effect on oral perception, including aging, denture wearing, and cognitive function. The aim of this study was to elucidate the impact of cognitive function on oral perception in independently living older individuals. The study sample was comprised of 987 participants (466 males, 521 females; age 69-71 years). Oral examinations, assessments of cognitive function in preclinical level by Montreal Cognitive Assessment (MoCA)-J, and determination of oral stereognostic ability as an indicator of oral perception were performed. Related variables were selected by univariate analyses; then, multivariate logistic regression model analysis was conducted. Univariate analyses revealed that number of teeth, removable dentures usage, and cognitive function respectively had a significant relationship with stereognostic score. Next, the subjects were classified into good and poor perception groups (lowest 17.4%) according to oral stereognostic ability. Logistic regression analysis revealed that lower cognitive function was significantly associated with poor oral perception (OR = 0.934, p = 0.017) after controlling for other variables. Cognitive decline even in preclinical stage was associated with reduced oral perception after controlling for gender, tooth number and denture use in independent living older people. This study suggested that preclinical level of change in cognitive function affected oral perception. Dental practitioners and caregivers may need to pay attention to reduced oral perception among older people even if they do not have trouble in daily life.

To assess the impact of children's dental health status (DHS) on their oral health-related quality of life (OHRQoL). Participants were 11- and 12-year-old children attending public schools in the Kuwait Capital Region. Children's DHS was evaluated by clinical examinations and presented using decayed, missed, filled teeth/surface (DMFT/dmft, DMFS/dmfs); restorative (RI), plaque (PI); and pulp, ulcers, fistula, abscess (PUFA) indices. Children's OHRQoL was assessed using Child's Perception Questionnaire 11-14 (CPQ11-14). Means (SD) and frequencies were used for data description. Different factors were analyzed as predictors of OHRQoL by logistic regression analysis. A total of 440 children aged 11-12 years (50.7 % females) participated in this cross-sectional study. Mean (SD) DMFT/dmft, RI, PI, and PUFA scores were 2.91(2.75), 0.21 (0.34), 3.59 (1.63), 0.31 (0.85), respectively. The mean total CPQ11-14 was 20.72 (16.81). Mean scores of oral-symptoms, functional-limitations, emotional and social well-being were 4.26 (3.32), 5.40 (4.92), 5.48 (6.15), and 5.33 (6.05), respectively. Children with more than four fillings were 95 % less likely to have had oral symptoms than those with no fillings. Children with a DMFT/dmft of 2-3 were 2.8 times more likely to have functional limitation than those with a DMFT/dmft of 0, while children with a DMFT/dmft of more than 4 were 4.4 times more likely to experience limitations. Having two or three non-cavitated lesions reduced the odds of having functional-limitation by 58 %. Children with more than four missing teeth were 45 % more likely to experience emotional stress. Having more than four fissure sealants reduced the odds of having emotional stress by 46 %. The increase in the number of carious teeth was associated with a limitation in oral functions. Preventive treatment had a positive impact on children's emotional well-being and restorative treatments improved their oral function.

Oral delivery of insulin for treatment of diabetes: status quo, challenges and opportunities.

PubMed

2016-09-01

Diabetes mellitus is characterised by progressive β-cell destruction and loss of function, or loss of ability of tissues to respond to insulin. Daily subcutaneous insulin injection is standard management for people with diabetes, although patient compliance is hard to achieve due to the inconvenience of injections, so other forms of delivery are being tested, including oral administration. This review summarises the developments in oral insulin administration. The PubMed database was consulted to compile this review comparing conventional subcutaneous injection of insulin to the desired oral delivery. Oral administration of insulin has potential benefits in reducing pain and chances of skin infection, improving the portal levels of insulin and avoiding side effects such as hyperinsulinemia, weight gain and hypoglycaemia. Although oral delivery of insulin is an ideal administration route for patients with diabetes, several physiological barriers have to be overcome. An expected low oral bioavailability can be attributed to its high molecular weight, susceptibility to enzymatic proteolysis and low diffusion rate across the mucin barrier. Strategies for increasing the bioavailability of oral insulin include the use of enzyme inhibitors, absorption enhancers, mucoadhesive polymers and chemical modification for endogenous receptor-mediated absorption. These may help significantly increase patient compliance and disease management. © 2016 Royal Pharmaceutical Society.

Effect of topical honey on limitation of radiation-induced oral mucositis: an intervention study.

PubMed

Khanal, B; Baliga, M; Uppal, N

2010-12-01

Radiation therapy for oral carcinoma is therapeutically useful in dose of at least 6000 cGy but causes mucositis that severely interferes with oral function. The literature indicates that honey appears to promote wound healing, so the authors investigated whether its anti-inflammatory properties might limit the severity of radiation-induced oral mucositis. A single-blinded, randomized, controlled clinical trial was carried out to compare the mucositis-limiting qualities of honey with lignocaine. A visual assessment scale permitted scoring of degrees of mucositis and statistical evaluation of the results was performed using the χ(2) test. Only 1 of 20 patients in the honey group developed intolerable oral mucositis compared with the lignocaine group, indicating that honey is strongly protective (RR=0.067) against the development of mucositis. The proportion of patients with intolerable oral mucositis was lower in the honey group and this was statistically significant (p=0.000). Honey applied topically to the oral mucosa of patients undergoing radiation therapy appears to provide a distinct benefit by limiting the severity of mucositis. Honey is readily available, affordable and well accepted by patients making it useful for improving the quality of life in irradiated patients.

Collagen hydrolysates (CHs) have been demonstrated to have positive effects on skin photoaging by topical application or oral ingestion. However, there has been little research on their influence on skin chronological aging. In this study, 9-month-old female ICR mice were given normal AIN-93M diets containing CHs (2.5, 5 and 10% w/w) from Nile tilapia scale. After 6 months, the collagen content and antioxidant enzyme (superoxide dismutase and glutathione peroxidase) activities increased significantly (P < 0.05), while the survival rate, viscera indices and contents of moisture, fat and non-collagenous protein in skin did not change (P > 0.05). The color, luster and quantity of hair were obviously ameliorated. Moreover, the structure of epidermis and dermis, the density and distribution of collagen fibers and the ratio of type I to type III collagen were improved in a dose-dependent manner as shown by histochemical staining. Oral ingestion of CHs increased the collagen content and antioxidant enzyme activities and improved the appearance and structure of skin. These results suggest the potential of CHs as an anti-skin-aging ingredient in nutraceuticals or functional foods. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

This retrospective study aimed to compare the therapeutic response, including side effects, for oral baclofen versus oral tizanidine therapy with adjuvant botulinum toxin type A in a group of 64 pediatric patients diagnosed with static encephalopathy and spastic equinus foot deformity. Following botulinum toxin A treatment, clinical improvement led to the gradual reduction of baclofen or tizanidine dosing to one-third of the former dose. Gross Motor Functional Measure and Caregiver Health Questionnaire scores were markedly elevated post-botulinum toxin A treatment, with scores for the tizanidine (Gross Motor Functional Measure: 74.45 ± 3.72; Caregiver Health Questionnaire: 72.43 ± 4.29) group significantly higher than for the baclofen group (Gross Motor Functional Measure: 68.23 ± 2.66; Caregiver Health Questionnaire: 67.53 ± 2.67, P < .001). These findings suggest that the combined use of botulinum toxin A and a low dose of tizanidine in treating children with cerebral palsy appears to be more effective and has fewer side effects versus baclofen with adjuvant botulinum toxin A. © The Author(s) 2015.

Bergamot (Citrus bergamia), a citrus fruit characterized by a high amount of flavonoids and flavonoid glycosides, may represent a potential nutraceutical approach to cognitive dysfunction. The present study was aimed to explore the efficacy of bergamot polyphenolic fraction (BPF) supplementation on cognitive/executive functioning in a sample of patients with schizophrenia receiving second-generation antipsychotics. Twenty outpatients treated with second-generation antipsychotics assumed BPF at an oral daily dose of 1000 mg/d for 8 weeks. Brief Psychiatric Rating Scale, Wisconsin Card Sorting Test (WCST), Verbal Fluency Task-Controlled Oral Word Association Test, and Stroop Color-Word Test were administered. At end point, (week 8) BPF supplementation significantly improved WCST "perseverative errors" (P = 0.004) and semantic fluency test (P = 0.004). Moreover, a trend for other cognitive variable (WCST "categories," phonemic fluency, and Stroop Color-Word Test) improvement was observed. The findings provide evidence that BPF administration may be proposed as a potential supplementation strategy to improve cognitive outcome in schizophrenia. Further clinical trials with adequately powered and well-designed methodology are needed to better explore the BPF effectiveness on cognitive impairments in patients with schizophrenia.

Oral intake of beta-hydroxy-beta-methylbutyrate (HMB), arginine, and glutamine may ameliorate muscle loss by stimulating protein synthesis and decreasing protein degradation while simultaneously decreasing inflammation. Previous studies provide evidence for improvement in body composition with dietary supplementation of these ingredients among patients with muscle-wasting diseases. The objectives of this study were to examine the effects of this amino acid mixture on lean body mass, muscle volume, and physical function among healthy older adults. Thirty-one community-dwelling men and women, aged 65-89 years, were randomized to either two oral doses of the amino acid supplement (totaling 3 g HMB, 14 g arginine, 14 g glutamine) or placebo daily for six months. At baseline and month six, lean body mass was measured by air displacement plethysmography, dual-energy X-ray absorptiometry (DXA), and four-compartment model. Muscle volume of quadriceps was quantified by magnetic resonance imaging (MRI), and participants performed a battery of tests to assess physical function. As compared to the placebo group, the treatment group exhibited improvement in a timed stair climb (p =.016) as well as significant increases in lean body mass by all methods of assessment (p <.05). Regional analysis by DXA revealed increased arm lean mass in the supplement group only (p =.035). However, no change was observed in MRI-derived quadriceps volume. Dietary supplementation with HMB, arginine, and glutamine improved total body lean mass among a small sample of healthy older adults. Further research is indicated to elucidate mechanisms of action and to determine whether supplementation may benefit frail elders. Registered under ClinicalTrials.gov identifier no. NCT01057082.

Neurofeedback training (NFT) has shown to be promising and useful to rehabilitate cognitive functions. Recently, brain-computer interfaces (BCIs) were used to restore brain plasticity by inducing brain activity with an NFT. In our study, we hypothesized that an NFT with a motor imagery-based BCI (MI-BCI) could enhance cognitive functions related to aging effects. To assess the effectiveness of our MI-BCI application, 63 subjects (older than 60 years) were recruited. This novel application was used by 31 subjects (NFT group). Their Luria neuropsychological test scores were compared with the remaining 32 subjects, who did not perform NFT (control group). Electroencephalogram changes measured by relative power (RP) endorsed cognitive potential findings under study: visuospatial, oral language, memory, intellectual and attention functions. Three frequency bands were selected to assess cognitive changes: 12, 18, and 21 Hz (bandwidth 3 Hz). Significant increases (p < 0.01) in the RP of these frequency bands were found. Moreover, results from cognitive tests showed significant improvements (p < 0.01) in four cognitive functions after performing five NFT sessions: visuospatial, oral language, memory, and intellectual. This established evidence in the association between NFT performed by a MI-BCI and enhanced cognitive performance. Therefore, it could be a novel approach to help elderly people.

To develop and evaluate an oral delivery system for salmon calcitonin. 2-Iminothiolane was covalently bound to chitosan in order to improve the mucoadhesive and cohesive properties of the polymer. The resulting chitosan-TBA conjugate (chitosan-4-thiobutylamidine conjugate) was homogenized with salmon calcitonin. mannitol, and a chitosan-Bowman-Birk inhibitor conjugate and a chitosan-elastatinal conjugate (6.75 + 0.25 + 1 + 1 + 1). Optionally 0.5% (m/m) reduced glutathione. used as permeation mediator, was added. Each mixture was compressed to 2 mg microtablets and enteric coated with a polymethacrylate. Biofeedback studies were performed in rats by oral administration of the delivery system and determination of the decrease in plasma calcium level as a function of time. Test formulations led to a significant (p < 0.005) decrease in the plasma calcium level of the dosed animals in comparison to control tablets being based on unmodified chitosan. The addition of glutathione in the tablets led to a further improvement in the oral bioavailability of salmon calcitonin with an earlier onset of action and a decrease in the calcium level of about 10% for at least 10 h. The combination of mucoadhesive thiolated chitosan, chitosan-enzyme-inhibitor conjugates and the permeation mediator glutathione seems to represent a promising strategy for the oral delivery of salmon calcitonin.

We report the results of a letter naming treatment designed to facilitate letter-by-letter reading in an aphasic patient with no reading ability. Patient M.R.'s anomia for written letters reflected two loci of impairment within visual naming: impaired letter activation from print (a deficit commonly seen in pure alexic patients who read letter by letter) and impaired access to phonology via semantics (documented in a severe multimodality anomia). Remarkably, M.R. retained an excellent ability to pronounce orally spelled words, demonstrating that abstract letter identities could be activated normally via spoken letter names, and also that lexical phonological representations were intact when accessed via spoken letter names. M.R.'s training in oral naming of written letters resulted in significant improvement in her oral naming of trained letters. Importantly, as M.R.'s letter naming improved, she became able to employ letter-by-letter reading as a compensatory strategy for oral word reading. M.R.'s success in letter naming and letter-by-letter reading suggests that other patients with a similar pattern of spared and impaired cognitive abilities may benefit from a similar treatment. Moreover, this study highlights the value of testing the pronunciation of orally spelled words in localizing the source of prelexical reading impairment and in predicting the functional outcome of treatment for impaired letter activation in reading.

Achieving optimal symptom control with minimal side effects is a major goal in clinical practice. Dual-agent dopamine receptor agonist (DA) therapy in Parkinson's disease (PD) may represent a promising approach to treatment, as the combination of different pharmacokinetic/pharmacological profiles may result in a lesser need for high dosages and, accordingly, may be well tolerated. The objective of the current study was to investigate safety and efficacy of rotigotine transdermal system as add-on to oral DA in patients with advanced PD inadequately controlled with levodopa and low-dose oral DA. PD0015 was an open-label, multinational study in patients with advanced-PD and sleep disturbance or early-morning motor impairment. Patients were titrated to optimal dose rotigotine (≤8 mg/24 h) over 1-4 weeks and maintained for 4-7 weeks (8-week treatment). Dosage of levodopa and oral DA (pramipexole ≤1.5 mg/day, ropinirole ≤6.0 mg/day) was stable. Primary variable was Clinical Global Impressions (CGI) item 4: side effects, assessing safety. Other variables included adverse events (AEs), Patient Global Impressions of Change (PGIC), Unified Parkinson's Disease Rating Scale (UPDRS) II and III, Parkinson's Disease Sleep Scale (PDSS-2), Pittsburgh Sleep Quality Index (PSQI), and "off" time. Of 90 patients who received rotigotine, 79 (88%) completed the study; 5 (6%) withdrew due to AEs. Most (83/89; 93%) had a CGI-4 score <3 indicating that rotigotine add-on therapy did not interfere with functioning; 6 (7%) experienced drug-related AEs that interfered with functioning (score ≥3). AEs occurring in ≥5% were application site pruritus (13%), dizziness (10%), orthostatic hypotension (10%), nausea (8%), dyskinesia (8%), and nasopharyngitis (6%). Numerical improvements in motor function (UPDRS III), activities of daily living (UPDRS II), sleep disturbances (PDSS-2, PSQI), and reduction in "off" time were observed. The majority (71/88; 81%) improved on PGIC. Addition of rotigotine transdermal system to low-dose oral DA in patients with advanced-PD was feasible and may be associated with clinical benefit.

This study aimed to determine the effectiveness of oral-hygiene instruction in improving oral health in 100 patients following oral hygiene instruction, with and without use of an intra-oral camera. The two groups of 50 patients were similar in age and sex distributions, frequency of caries, plaque accumulation and gingival bleeding. Prospective improvements in oral hygiene and compliance were measured by means of plaque levels and gingival bleeding at baseline and four weeks later. While both groups showed a clear reduction in plaque accumulation, the test group benefited from the use of the intra-oral camera. A majority of patients (88 per cent) thought that the extra information provided by the camera was helpful and desirable. This study demonstrates that the intra-oral camera can effectively augment oral-hygiene instruction and help create improvements in patient compliance.

Management of the postoperative response to surgical stress is an important issue in major surgery. Avoiding preoperative fasting using preoperative oral carbohydrates (POC) has been suggested as a measure to prevent and reduce the extent to which such derangements occur. This review summarizes the current evidence and rationale for this treatment. A recent review from the Cochrane Collaboration reports enhanced gastrointestinal recovery and shorter hospital stay with the use of POC with no effect on postoperative complication rates. Multiple randomized controlled trials demonstrate improved postoperative metabolic response after POC administration, including reduced insulin resistance, protein sparing, improved muscle function and preserved immune response. Cohort studies in patients undergoing major abdominal surgery have shown that the use of POC as part of an enhanced recovery after surgery protocol is a significant predictor for improved clinical outcomes. Avoiding preoperative fasting with POC is associated with attenuated postoperative insulin resistance, improved metabolic response, enhanced perioperative well-being, and better clinical outcomes. The impact is greatest for patients undergoing major surgeries.

To explore the effects on thyroid function in patients of Hashimoto's thyroiditis treated with aconite cake-separated moxibustion and option the better therapeutic program. Eighty-five cases were randomly divided into a moxibustion group (42 cases) and a western medication group (43 cases). The moxibustion group was treated by aconite cake-separated moxibustion therapy with acupoints of two groups [(1) Danzhong (CV 17), Zhongwan (CV 12), Guanyuan (CV 4); (2) Dazhui (GV 14), Shenshu (BL 23), Mingmen (GV 4)] alternatively and oral administration of 25 microg Euthyrox everyday. The western medication group was oral administration of 25 microg Euthyrox everyday. Indices of thyroid function before and after treatment and clinical effect were compared between two groups. The clinical total effective rate and effective rate of thyroid function were 25.0% (10/40), 87.5% (35/40) in moxibustion group respectively, 7.53% (3/40) and 57.5% (23/40) in western medication group, with significant differences between two groups (both P < 0.05). Content of serum free thyroxine index (FT4) increased significantly in the moxibustion group after treatment (P < 0.01); content of serum supersensitive thyrotropin (S-TSH) in the moxibustion group was lower than that of western medication group, and contents of serum FT4 and free triiodothyronine (FT3) were higher than those of western medication group, but with no significant differences (all P > 0.05). Aconite cake-separated moxibustion at Guanyuan (CV 4) and Mingmen (GV 4) combined with oral administration of Euthyrox can improve clinical symptoms and thyroid function in patients of Hashimoto's thyroiditis, which is better than simple oral administration of Euthyrox.

The oral rehabilitation with conventional removable partial dentures in Kennedy class I patients allows continuous bone resorption, dislodgment of the prosthesis during the mastication caused by the resilience of the mucosa, and rotation of the prosthesis. Thus, the associations of distal implants become an attractive modality of treatment for these patients. This case report presented an association of removable partial dentures, milled crowns and osseointegrated implants to rehabilitate a partial edentulous patient. A removable partial denture associated with implants and metal-ceramic milled crowns can offer excellent esthetics, and will improve function and biomechanics, at a reduced cost.

It is a commonly held belief that combined oral contraceptive (COC) pills containing an androgenic progestin may be less likely to impair sexual function than COCs containing an anti-androgenic progestin. The study aims to compare the effects of a COC containing a progestin with an anti-androgenic profile (estradiol valerate [E2 V]/dienogest [DNG]) to that of one with an androgenic progestin (ethinyl estradiol [EE]/levonorgestrel [LNG]) on sexual function in women with COC-associated sexual dysfunction. In this multicenter, randomized, double-blind, noninferiority study, women with COC-associated female sexual dysfunction (FSD) were randomized to E2 V/DNG or EE/LNG for six cycles. The primary outcome was the change in the sum of Female Sexual Function Index (FSFI) desire and arousal component scores between baseline and cycle 6. Secondary outcome measures included changes to the FSFI domains, the Female Sexual Distress Scale (FSDS-R), Vaginal Health Assessment, the Atrophy Symptom Questionnaire, and the Psychological General Well Being Index over six treatment cycles. The main outcome is the change in the sum of FSFI desire and arousal component scores between baseline and cycle 6. Of 276 women screened, 213 received treatment and 191 completed the study. The mean increase in the sum of FSFI desire and arousal component scores was 5.90 (standard deviation [SD] 5.45) for E2 V/DNG and 5.79 (SD 6.17) for EE/LNG (change from baseline P < 0.0001, both groups). Both treatments showed equal efficacy and were associated with improvements in all domains of the FSFI, with no between-group differences. Both COCs reduced the distress associated with FSD, as indicated by reduced FSDS-R scores. In women with COC-associated FSD, switching to either E2 V/DNG or EE/LNG was associated with equivalent improvements in symptoms, challenging the perception that COCs containing anti-androgenic progestins have a detrimental effect on sexual function relative to those containing androgenic progestins. © 2013 International Society for Sexual Medicine.

The purpose of this review is to conduct a systematic review and meta-analysis comparing the effects of continuous positive airway pressure (CPAP) with a mandibular advancement device (MAD) in improving the quality of life (sleepiness, cognitive, and functional outcomes) in patients diagnosed with obstructive sleep apnea (OSA). Authors identified randomized, placebo-controlled studies from MEDLINE through PubMed, Web of Science, and the Cochrane Library. Studies were assessed for inclusion and exclusion criteria, as well as risk of bias. Initial search yielded 240 unduplicated references, which the authors reduced to 12 relevant studies. Patients with CPAP therapy showed no statistically significant difference in the post-treatment quality of life measured with the SF-36 mental health component (p = .994), or the SF-36 physical functioning component (p = .827). There was no significant improvement in neither Functional Outcomes of Sleep Questionnaire (p = .788) nor cognitive performance (p = .395) compared to patients treated with oral appliances. However, the meta-analyses' overall results showed a significant improvement in the post-treatment apnea-hypopnea index (AHI) in favor of CPAP therapy as compared with the oral appliance group (p < .001). Meta-analyses showed unclear results for sleepiness with no significant differences in average post-treatment Epworth Sleepiness Scale [ESS] (p = .203), but significant differences in change in ESS from baseline favorable to CPAP treatment (p = .047). Further studies are needed. Compliance with treatment was 1.1 h per night significantly lower with CPAP than MAD (p = .004), which could explain why though efficacy (AHI) is better with CPAP, no significant results are shown for quality of life, cognitive, and functional outcomes. Though CPAP is significantly more efficient in reducing AHI (moderate quality of evidence), it has a significantly lower compliance resulting in no differences with MAD in quality of life, cognitive, or functional outcomes. Sleep medicine professionals should monitor treatment compliance and offer patients non-compliant with CPAP an oral appliance for treatment of OSA.

Various distresses appear in the terminal stage of cancer. Oral problems including dry mouth, stomatitis and candidiasis are one of the important problems which should be resolved. The purpose of this study was to investigate oral problems in this stage and improvement of dry mouth by oral care. The study subjects were consecutive terminally ill cancer patients admitted over the past 2 years. Patients were divided based on the status of oral food intake into good oral food intake group (≥30%) and poor oral food intake group. The following 3 items were retrospectively investigated: 1) The incidences of these oral problems, 2) Severity of dry mouth and complication with other oral problems, 3) Improvement of dry mouth using standard oral care by nursing staff and specialist oral care including dentists as needed. There were 115 and 158 patients in good and poor oral intake groups, respectively. 1) The incidences of dry mouth, stomatitis, and candidiasis were significantly higher in poor oral intake group ( p < 0.001). 2) Severe cases of dry mouth (Grade-2&3) were noted in 20.0% and 64.8% in good and poor oral intake groups, respectively ( p < 0.0001). Candidiasis complication rate was significantly higher in poor oral intake group ( p = 0.0002). 3) The rate of dry mouth improvement by oral care was 100% in Grade-1, 86% in Grade-2 and 81% in Grade-3. Oral problems occur in many of terminally ill cancer patients. Accurate diagnosis of oral problems and corresponding appropriate interventions are important for improving quality of end-of-life care.

Neuromuscular electrical stimulation with muscle contraction, administered through the skin of the neck, improves a patient's swallowing ability. However, the beneficial effects of transcutaneous electrical sensory stimulation (TESS), without muscle contraction, are controversial. We investigated the effect of TESS, using interferential current, in patients undergoing dysphagia rehabilitation. This double-blind, randomized controlled trial involved 43 patients who were prescribed in-hospital dysphagia rehabilitation for ≥3 weeks. Patients were randomly assigned to the sensory stimulation (SS) or sham groups; all received usual rehabilitative care plus 2 weeks of SS or sham intervention. Outcome measures included cough latency times against a 1% citric acid mist, functional oral intake scale (FOIS) scores, and oral nutritional intake - each determined after the second and third week following treatment initiation. Mean patient age was 84.3±7.5 years; 58% were women. The SS and sham groups had similar baseline characteristics. Changes in cough latency time at 2 weeks (-14.1±14.0 vs -5.2±14.2 s, p =0.047) and oral nutrition intake at 3 weeks (437±575 vs 138±315 kcal/day, p =0.042) improved more in the SS group than in the sham group. Changes in cough frequency and FOIS scores indicated better outcomes in the SS group, based on substantial effect sizes. TESS, using interferential current through the neck, improved airway defense and nutrition in patients suffering from dysphagia. Further large-scale studies are needed to confirm the technique's effect on swallowing ability.

Head Start and Early Head Start (HS/EHS) programs have partnered with the American Academy of Pediatric Dentistry to promote oral health and increase access to dental homes. Preparing HS/EHS staff for issues related to pediatric oral health promises to improve effectiveness of this collaboration. This paper's purpose was to describe the Columbia Head Start Oral Health Program (C-HSOHP) and changes in HS/EHS staff pediatric oral health knowledge and competencies after participating in C-HSOHP. Four HS/EHS grantees in New York City engaged in the 2008-09 C-HSOHP. A convenience sample of 61 staff completed pre- and postself assessments of knowledge and competencies. Significant paired mean improvements were found for staff-reported level of preparation to explain dental issues during pregnancy, the tooth decay process, and preparing parents for their child's first dental visit. Significant improvements were found in staff confidence in teaching parents about children's oral health issues, referring for pediatric dental services, and talking to a dentist about a concern. The Columbia Head Start Oral Health Program was effective in improving Head Start/Early Head Start staff self-confidence and self-perceived preparedness in teaching parents about oral health, applying oral health knowledge to HS/EHS programs, communicating with dental professionals, and improving access to pediatric dental services.

The efficacy of full mouth rehabilitation (FMR) on oral health-related quality of life of physically disabled children was assessed. This prospective study was performed at Dental Department of Sultan Bin Abdulaziz Humanitarian City, Riyadh, and King Abdulaziz University Hospital, Jeddah, Saudi Arabia, during May 2012 to September 2014. A total of 186 physically disabled children aged 11-14 years were assigned to a test group (n = 97) or a control group (n = 89). FMR was applied for test group children at baseline and 3 months' visits, whereas those in the control group did not receive FMR. Both group children received dental kits and oral hygiene instructions. Children were asked to complete the Child Perceptions Questionnaire, whereas Parental-Caregiver Perceptions Questionnaire and Family Distress Domain questionnaire were completed by the parents/caregivers at baseline and 6 months' visits. Children in both groups showed positive trends in oral symptoms at 6 months compared with those at baseline. However, when they were compared to control, significant improvement in oral symptoms was observed in the test group at 6 months' visit (p < .05). Also when they were compared to control, significant improvements were observed in the functional limitation, emotional, and social well-being subscales of the Child Perceptions Questionnaire and on the Parental-Caregiver Perceptions Questionnaire scales at the end of the study (p < .05). Compared to the parents/caregivers of the control children, the parents/caregivers of the test-group children reported insignificant but positive trends in Family Distress Domain at the end of the study (p < .05). FMR in children reduced oral-related problems subsequently to a better oral health-related quality of life.

The healing pattern after surgical resection of tumors of the oral cavity involving the maxilla may vary from one patient to another. The result may be open communication between the oral and nasal cavities (open defect) or complete oronasal separation after healing of the defect area (closed defect). The purpose of this clinical study was to compare masticatory function and oral health-related quality of life (OHRQoL) between patients with closed and open defects who had undergone a partial maxillectomy and were wearing dentomaxillary prostheses. Thirty-eight participants who had undergone a partial maxillectomy and who were wearing dentomaxillary prostheses were enrolled between September 2014 and April 2016. Participants were assigned to 2 groups according to the type of defect after healing: 19 participants had a closed defect, and 19 participants had an open defect. Masticatory function was evaluated objectively and subjectively. The objective measurement was food-mixing ability, which was assessed using color-changeable chewing gum. The subjective measurement was perceived mastication ability, rated as a masticatory score based on the patient's responses to a 35-item food intake questionnaire. OHRQoL was assessed using the Geriatric Oral Health Assessment Index (GOHAI). The GOHAI questionnaire consists of 12 items reflecting 3 hypothesized domains of the impact of oral disease: physical function, psychosocial function, and pain or discomfort. Differences in the scores obtained by the 3 measurements were compared between the 2 groups, using the Wilcoxon rank-sum test (α=.05). No significant differences were seen between the 2 groups in objective mixing ability, subjective masticatory score, or GOHAI (P>.05). Regarding the GOHAI physical function domain, only the swallowing item was significantly lower (P=.025) in participants with an open defect than in participants with a closed defect. Regarding the GOHAI psychological function domain, the item related to patients' psychological worries or concerns about their teeth, gingival tissue, or dentures was significantly lower (P=.045) in patients with an open defect than in those with a closed defect. Other items related to physical function, psychological function, and pain or discomfort were not significantly different (P>.05) between the 2 groups. The closed or open defect in patients who had undergone a partial maxillectomy may not influence patients' masticatory function and overall OHRQoL if they have adequate prosthetic rehabilitation. However, special consideration should be given to patients with an open defect with regard to swallowing function and psychological concerns in order to improve their OHRQoL.

To evaluate the efficacy and safety of memantine hydrochloride as an adjunct to stimulant pharmacotherapy for treating executive function deficits (EFDs) in adults with ADHD. This was a 12-week, double-blind, placebo-controlled, randomized clinical trial of memantine added to open-label treatment with stimulant medication. Because of the small sample size, we considered a standardized mean difference (equivalent to effect size) of ≥0.5 and odds ratios ≥2 as indicators of trend improvements. Twelve participants received memantine and 14 received a placebo. Trend improvements favoring memantine were observed on Behavior Rating Inventory of Executive Functions-Adult Inhibition and Self-Monitor subscales when compared with Placebo. No significant changes were noted on the Cambridge Neuropsychological Test Automated Battery. Among adults with ADHD and EFDs, adjunct treatment with memantine to osmotic release oral system-methylphenidate (OROS-MPH) was associated with improvements in selective areas of executive functioning, supporting the need for further research.

The effect of renewing removable dentures on masticatory function was evaluated according to the occlusion offered by different types of mandibular arches. Twenty-eight patients with complete maxillary dentures were subdivided into three groups in terms of mandibular dentition type: dentate, partial denture, and complete denture. The participants were observed before and 8 weeks after maxillary denture renewal. The mandibular denture was also renewed in the partial and complete denture groups. The participants masticated carrots, peanuts, and three model foods of different hardnesses. The particle size distribution of the boluses obtained from natural foods was characterized by the median particle size (d50) in relation to the masticatory normative indicator (MNI). Chewing time (CT), number of chewing cycles (CC), and chewing frequency (CF) were video recorded. A self-assessment questionnaire for oral health-related quality of life (Geriatric Oral Health Assessment Index [GOHAI]) was used. Statistical analyses were carried out with a mixed model. Renewal of the dentures decreased d50 (P < .001). The number of participants with d50 values above the MNI cutoff decreased from 12 to 2 after renewal. Renewal induced an increase in mean CF while chewing model foods (P < .001). With all foods, renewal tended to affect CT, CC, and CF differently among the three groups (statistically significant renewal Å~ group interactions). The GOHAI score increased significantly for all groups. Denture renewal improves masticatory function. The complete denture group benefited least from renewal; the dentate group benefited most. This study confirmed the usefulness of denture renewal for improving functions and oral health- related quality of life.

Objectives To investigate the challenges of providing oral health advice/treatment as experienced by non-dental primary care providers in rural and remote areas with no resident dentist, and their views on ways in which oral health and oral health services could be improved for their communities. Design Qualitative study with semistructured interviews and thematic analysis. Setting Four remote communities in outback Queensland, Australia. Participants 35 primary care providers who had experience in providing oral health advice to patients and four dental care providers who had provided oral health services to patients from the four communities. Results In the absence of a resident dentist, rural and remote residents did present to non-dental primary care providers with oral health problems such as toothache, abscess, oral/gum infection and sore mouth for treatment and advice. Themes emerged from the interview data around communication challenges and strategies to improve oral health. Although, non-dental care providers commonly advised patients to see a dentist, they rarely communicated with the dentist in the nearest regional town. Participants proposed that oral health could be improved by: enabling access to dental practitioners, educating communities on preventive oral healthcare, and building the skills and knowledge base of non-dental primary care providers in the field of oral health. Conclusions Prevention is a cornerstone to better oral health in rural and remote communities as well as in more urbanised communities. Strategies to improve the provision of dental services by either visiting or resident dental practitioners should include scope to provide community-based oral health promotion activities, and to engage more closely with other primary care service providers in these small communities.

To examine the effects of the Intensive Dysphagia Rehabilitation approach on physiological and functional swallowing outcomes in adults with neurogenic dysphagia. Intervention study; before-after trial with 4-week follow-up through an online survey. Outpatient university clinics. A consecutive sample of subjects (N=10) recruited from outpatient university clinics. All subjects were diagnosed with adult-onset neurologic injury or disease. Dysphagia diagnosis was confirmed through clinical and endoscopic swallowing evaluations. No subjects withdrew from the study. Participants completed the 4-week Intensive Dysphagia Rehabilitation protocol, including 2 oropharyngeal exercise regimens, a targeted swallowing routine using salient stimuli, and caregiver participation. Treatment included hourly sessions twice per week and home practice for approximately 45 min/d. Outcome measures assessed pre- and posttreatment included airway safety using an 8-point Penetration Aspiration Scale, lingual isometric pressures, self-reported swallowing-related quality of life (QOL), and level of oral intake. Also, patients were monitored for adverse dysphagia-related effects. QOL and adverse effects were also assessed at the 4-week follow-up (online survey). The Intensive Dysphagia Rehabilitation approach was effective in improving maximum and mean Penetration Aspiration Scale scores (P<.05, η(2)=.8146 and P<.05, η(2)=.799708, respectively) and level of oral intake (P<.005, Cohen d=-1.387). Of the 5 patients who were feeding tube dependent initially, 2 progressed to total oral nutrition, and 2 progressed to partial oral nutrition. One patient remained tube dependent. QOL was significantly improved at the 4-week follow-up (95% confidence interval, 6.38-14.5; P<.00), but not at the posttreatment. No adverse effects were observed/reported. The Intensive Dysphagia Rehabilitation approach was safe and improved physiological and some functional swallowing outcomes in our sample; however, further investigation is needed before it can be widely applied.

2011-01-01

Several forms of epidermolysis bullosa (EB) present oral manifestations. Blistering of the (peri)oral mucosa affects the opening of the mouth, the mobility of the tongue and lips, thereby restricting oral functions. We describe the prevalence and characteristics of oral manifestations of EB in relation to loss of oral functions in a cross-sectional study of different types of EB patients using standardized measurement techniques. Twenty-two patients were included. The mobility of the mandible, lips and tongue was measured, the mandibular function impairment questionnaire (MFIQ) was filled out and additional questions regarding hindrance of EB during oral hygiene and intelligibility of speech (being understood) were asked in structured interviews. The median age was 11.8 yrs. Mobility of the mandible, tongue and lip was restricted, oral hygiene procedures were hindered in most patients. A data comparison was made between the recessive dystrophic EB (RDEB) and junctional EB (JEB) groups. Mandibular function was impaired in both groups but more severely in the RDEB-population. Intelligibility in both groups was almost unaffected. Restrictions in mobility of the mouth, tongue and lips are frequently present in EB patients. These are most severe in the RDEB group and support the clinical relevance of optimizing symptomatic treatment.

The oral microbiome plays a relevant role in the health status of the host and is a key element in a variety of oral and non-oral diseases. Despite advances in our knowledge of changes in microbial composition associated with different health conditions the functional aspects of the oral microbiome that lead to dysbiosis remain for the most part unknown. In this review, we discuss the progress made towards understanding the functional role of the oral microbiome in health and disease and how novel technologies are expanding our knowledge on this subject.

Whether malnutrition risk correlates with recovery of swallowing function of convalescent stroke patients is unknown. This study was conducted to clarify whether malnutrition risks predict achievement of full oral intake in convalescent stroke patients undergoing enteral nutrition. We conducted a secondary analysis of 466 convalescent stroke patients, aged 65 years or over, who were undergoing enteral nutrition. Patients were extracted from the "Algorithm for Post-stroke Patients to improve oral intake Level; APPLE" study database compiled at the Kaifukuki (convalescent) rehabilitation wards. Malnutrition risk was determined by the Geriatric Nutritional Risk Index as follows: severe (<82), moderate (82 to <92), mild (92 to <98), and no malnutrition risks (≥98). Swallowing function was assessed by Fujishima's swallowing grade (FSG) on admission and discharge. The primary outcome was achievement of full oral intake, indicated by FSG ≥ 7. Binary logistic regression analysis was performed to identify predictive factors, including malnutrition risk, for achieving full oral intake. Estimated hazard risk was computed by Cox's hazard model. Of the 466 individuals, 264 were ultimately included in this study. Participants with severe malnutrition risk showed a significantly lower proportion of achievement of full oral intake than lower severity groups (P = 0.001). After adjusting for potential confounders, binary logistic regression analysis showed that patients with severe malnutrition risk were less likely to achieve full oral intake (adjusted odds ratio: 0.232, 95% confidence interval [95% CI]: 0.047-1.141). Cox's proportional hazard model revealed that severe malnutrition risk was an independent predictor of full oral intake (adjusted hazard ratio: 0.374, 95% CI: 0.166-0.842). Compared to patients who did not achieve full oral intake, patients who achieved full oral intake had significantly higher energy intake, but there was no difference in protein intake and weight change. Severe malnutrition risk independently predicts the achievement of full oral intake in convalescent stroke patients undergoing enteral nutrition.

Malnutrition and cognitive impairment lead to declines in activities of daily living (ADL). Nutritional status and cognitive ability have been shown to correlate with oral health status and swallowing function. However, the complex relationship among the factors that affect decline in ADL is not understood. We examined direct and indirect relationships among oral health status, swallowing function, nutritional status, cognitive ability, and ADL in Japanese elderly people living at home and receiving home care services because of physical disabilities. Participants were 286 subjects aged 60 years and older (mean age, 84.5±7.9 years) living at home and receiving home care services. Oral health status (the number of teeth and wearing dentures) was assessed, and swallowing function was examined using cervical auscultation. Additionally, ADL, cognitive ability, and nutritional status were assessed using the Barthel Index, the Clinical Dementia Rating Scale, and the Mini Nutritional Assessment-Short Form, respectively. Path analysis was used to test pathways from these factors to ADL. The mean number of teeth present in the participants was 8.6±9.9 (edentates, 40.6%). Dysphagia, malnutrition, and severe cognitive impairment were found in 31.1%, 14.0%, and 21.3% of the participants, respectively. Path analysis indicated that poor oral health status and cognitive impairment had a direct effect on denture wearing, and the consequent dysphagia, in addition to cognitive impairment, was positively associated with malnutrition. Malnutrition as well as dysphagia and cognitive impairment directly limited ADL. A lower number of teeth are positively related to swallowing dysfunction, whereas denture wearing contributes to recovery of swallowing function. Dysphagia, cognitive impairment, and malnutrition directly and indirectly decreased ADL in elderly people living at home and receiving home nursing care. The findings suggest that preventing tooth loss and encouraging denture wearing when teeth are lost may indirectly contribute to maintaining or improving ADL, mediated by recovery of swallowing function and nutritional status. © 2012 John Wiley & Sons A/S.

2017-02-01

Candesartan cilexetil (CC), an antihypertensive drug, has low oral bioavailability due to poor solubility and hepatic first-pass metabolism. These are major limitations in oral delivery of CC. Several approaches are known to reduce the problems of solubility and improve the bioavailability of CC. Among various approaches, nanotechnology-based delivery of CC has potential to overcome the challenges associated with the oral administration. This review focuses on various nano-based delivery systems available and tried for improving the aqueous solubility, dissolution and consequently bioavailability of CC upon oral administration. Of all, solid lipid nanoparticles appear to be promising delivery system, based on current reported results, for delivery of CC, as this system improved the oral bioavailability and possessed prolonged pharmacodynamic effect.

The objective of this study was to test the construct validity of the patient-reported outcomes Swallowing Quality of Life Questionnaire (SWAL-QOL) and Speech Handicap Index (SHI) in relation to objectively measured oral function among patients treated for oral or oropharyngeal cancer. The study sample consisted of patients treated for oral or oropharyngeal cancer. Outcome measures were the SWAL-QOL and the SHI, and the Functional Rehabilitation Outcomes Grade (FROG), a test to measure oral and shoulder function. Spearman's rank correlation coefficient was used to test associations between the SHI and SWAL-QOL scales, and the FROG scales. During a study period of 3 months, 38 patients (21 males, 17 females; mean age 54 years) were included who visited the outpatient clinic for follow-up care 6-155 months after surgical treatment (n = 14) or combined surgery and radiotherapy (n = 24) for oral (n = 21) or oropharyngeal cancer (n = 17). Most SWAL-QOL and SHI scales (except the SWAL-QOL Fatigue scale) correlated significantly with one or more FROG oral function scales. None of the SWAL-QOL and SHI scales correlated significantly with the FROG shoulder function scale. These results support the construct validity of the SWAL-QOL and SHI questionnaires for assessing speech and swallowing problems in daily life that are moderately but significantly related to oral function. A multidimensional assessment protocol is recommended for use in clinical practice and for research purposes for measuring oral function and swallowing- and speech-related problems in daily life among head and neck cancer patients.

The objective of the study was to examine the mediating effect of child dental use on the effectiveness of North Carolina Early Head Start (EHS) in improving oral health–related quality of life (OHRQoL). In total, 479 parents of children enrolled in EHS and 699 parents of Medicaid-matched children were interviewed at baseline when children were approximately 10 mo old and 24 mo later. In this quasi-experimental study, mediation analysis was performed using the counterfactual framework analysis, which employed 2 logit models with random effects: 1) for the mediator as a function of the treatment and covariates and 2) for the outcome as a function of the treatment, mediator, and covariates. The covariates were baseline dental OHRQoL, dental need, survey language, and a propensity score. We used in-person computer-assisted, structured interviews to collect information on demographic characteristics and dental use and to administer the Early Childhood Oral Health Impact Scale, a measure of OHRQoL. Dental use had a mediation effect in the undesired direction with a 2–percentage point increase in the probability of any negative impact to OHRQoL (95% confidence interval [CI], 0.3%–3.9%). Even with higher dental use by EHS participants, the probability of any negative impact to OHRQoL was approximately 8 percentage points lower if an individual were moved from the non-EHS group to the EHS group (95% CI, −13.9% to −1.2%). EHS increases child dental use, which worsens family OHRQoL. However, EHS is associated with improved OHRQoL overall. Knowledge Transfer Statement: Study results can inform policy makers that comprehensive early childhood education programs improve oral health–related quality of life (OHRQoL) for disadvantaged families with young children in pathways outside of clinical dental care. This awareness and its promotion can lead to greater resource investments in early childhood education programs. Information about the negative impacts of dental use on OHRQoL should lead to the development and testing of strategies in dentistry and Early Head Start to improve dental care experiences.

Background To date, there are no studies reported in the literature on the possible use of bovine collagen, oxidized regenerated cellulose, or synthetic hyaluronic acid medications in the oral cavity. The aim of this paper is to report the use of bovine collagen, oxidized regenerated cellulose, and synthetic hyaluronic acid medications to improve wound healing in the oral cavity by stimulating granulomatous tissue. Methods From 2007 to 2011, 80 patients (median age 67 years) suffering from oral mucosal lesions participated in this double-blind study. The patients were divided into two groups, each consisting of 40 patients. One group received conventional medications, while the other group of patients were treated with the advanced medications. Results Advanced medications allowed re-epithelialization of the wound margin in 2–20 days, whereas patients receiving conventional medication showed a median healing duration of 45 days. Conclusion The results of this study demonstrate that treating oral mucosal wounds with advanced medication has an advantage with regard to wound healing time, allowing patients to have a rapid, functional, and esthetic recovery.

CO2 lasers in the management of potentially malignant and malignant oral disorders

PubMed Central

2012-01-01

The CO2 laser was invented in 1963 by Kumar Patel. Since the early 1970s, CO2 laser has proved to be an effective method of treatment for patients with several types of oral lesions, including early squamous cell carcinoma. Laser surgery of oral premalignant disorders is an effective tool in a complete management strategy which includes careful clinical follow-up, patient education to eliminate risk factors, reporting and biopsying of suspicious lesions and any other significant lesions. However, in a number of patients, recurrence and progression to malignancy remains a risk. CO2 laser resection has become the preferred treatment for small oral and oropharyngeal carcinomas. Laser resection does not require reconstructive surgery. There is minimal scarring and thus, optimum functional results can be expected. New and improved applications of laser surgery in the treatment of oral and maxillofacial/head and neck disorders are being explored. As more surgeons become experienced in the use of lasers and as our knowledge of the capabilities and advantages of this tool expands, lasers may play a significant role in the management of different pathologies.

Although mast cells (MCs) have been discovered over 130 years ago, their function was almost exclusively linked to allergic affections. At the time being, it is well known that MCs possess a great variety of roles, in both physiologic and pathologic conditions. In the oral tissues, MCs release different proinflammatory cytokines, tumor necrosis factor alpha (TNF-α), that promote leukocyte infiltration in various inflammatory states of the oral cavity. These cells play a key role in the inflammatory process and, as a consequence, their number changes in different pathologic conditions of the oral cavity, like gingivitis, periodontitis, and so on. MCs also represent a rich source of proteases, especially of mast cell tryptase and chymase, which directly degrade the extracellular matrix through their proteolytic activity and thus indirectly stimulate angiogenesis and facilitate invasion and metastasis. It may be stated that mast cells could have an impact on primary tumor development, progression, and metastases in oral squamous cell carcinoma. By understanding the role of mast cells in the pathogenesis of different inflammatory and tumor diseases of the oral cavity, these cells may become therapeutic targets that could possibly improve the prognosis and survival of these patients.

Simultaneous Effect of Thiolation and Carboxylation of Chitosan Particles Towards Mucoadhesive Oral Insulin Delivery Applications: An In Vitro and In Vivo Evaluation.

PubMed

Rekha, M R; Sharma, Chandra P

2015-01-01

Thiomalyl chitosan (TCS), a pH sensitive thiolated chitosan derivative, was developed and investigated towards oral protein delivery application. Particles of z-average 364 ± 5.6 nm with a negative zeta potential of 14.4 mV was obtained by tripolyphosphate cross linking of TCS. The release of insulin from TCS particles was significantly restricted at pH 1.2 minimizing up to about < 10% in 3 hours. The permeation enhancement ratio was found to 13 times higher than the FD4 alone and was 1.6 times higher than the unmodified chitosan particles. The protein protective properties of the matrix were established in presence of pepsin and pancreatic enzymes. Confocal microscopy studies proved the tight junction opening of Caco-2 cells by these thiolated chitosan particles and the in vivo studies on diabetic rats established its potential towards oral peptide delivery with pharmacological availability (PA) of 1.5%. The significance of this work is to establish that, the presence of multiple functional groups having similar property in the same matrix can improve its suitability as a promising candidate for oral peptide delivery with improved release characteristics, mucoadhesion as well as protecting the insulin activity and enhancing the permeability across the intestinal wall.

Objective. To evaluate the efficacy and safety of oral Huangqi formulae for the treatment of stable COPD. Methods. The major databases were searched until September 2010 and supplemented with a manual search. Randomized controlled trials (RCTs) of oral Huangqi formulae that reported on lung function, St. George's Respiratory Questionnaire, symptom improvement and/or frequency of exacerbations were extracted by two reviewers. The Cochrane tool was used for the assessment of risk of bias in the included trials. Data were analyzed with RevMan 5.1.2 software. Results. 25 RCTs (1,661 participants) were included. Compared with conventional therapy (CT) alone, oral Huangqi formulae plus CT increased FEV1, and a similar result was found comparing Huangqi formulae with no treatment. Improvements in SGRQ total score, COPD-related symptoms and reduction of frequency of exacerbations were found in patients receiving Huangqi formulae plus CT compared to those receiving CT alone or CT plus placebo. No serious adverse events were reported. However, there were some methodological inadequacies in the included studies. Conclusions. The benefits of Huangqi formulae for stable COPD were promising, but its efficacy and safety have not been established due to methodological weakness and possible bias in the reported results. Further rigorously designed studies are warranted. PMID:23606889

Acne vulgaris is a debilitating disorder and requires proper treatment. This work evaluates the clinical efficacy, side effects, and laboratory changes of serum lipids and liver function during oral isotretinoin therapy for acne vulgaris, comparing single versus twice daily dose. Fifty-eight patients with acne vulgaris were included and randomized into group I (26 patients), who received once daily dose, and group II (32 patients), who received twice daily dose of oral isotretinoin. Global acne scoring system was used to evaluate acne severity and post-treatment improvement. Both regimens resulted in highly significant clinical improvement of acne with no significant difference. However, side effects were significantly more common among patients of group I. Both regimens caused mild rise of serum cholesterol, alanine transaminase (ALT), and aspartate aminotransferase (AST) with more prominent rise of triglycerides especially with twice daily dose. Oral isotretinoin is a very effective treatment for acne vulgaris with no statistically significant difference in clinical efficacy between once and twice daily doses. However, dividing dose to twice per day might cause fewer incidence of side effects without reducing clinical efficacy. The drug causes mild clinically insignificant rise of serum cholesterol, triglycerides, AST, and ALT. © 2015 Wiley Periodicals, Inc.

A double-blinded parallel randomized controlled clinical trial was conducted on two groups of colorectal cancer patients to study the therapeutic benefit of orally administered bovine lactoferrin (bLF) on colorectal cancer patients having age ranges from 20 to 71 years and who received 5-fluorouracil and leucovorin calcium. Test group (15 patients) received oral bLF 250 mg/day beside chemotherapy for three months. Control group (15 patients) received chemotherapy only. Serum lactoferrin (LF), serum glutathione-s-transferase enzyme (GST), interferon gamma (INF-γ), tumor marker carcinoembryonic antigen (CEA), renal function tests, hepatic function tests, and complete blood count were measured for both groups before and at the end of the trial. Although, there was a significant effect of oral bLF (250 mg/day) that indicated a significant improvement in mean percent of change of all parameters 3 months after treatment, there was no significant difference between results of patients in the test group and patients in the control group after treatment. This result suggests that oral bLF has significant therapeutic effect on colorectal cancer patients. Our study suggests that daily administration of bLF showed a clinically beneficial effect to colorectal cancer patients with better disease prognosis but that needs further looking into.

People with disability are subject to inequality in oral health both in terms of prevalence of disease and unmet healthcare needs. Over 18% of the global population is living with moderate to severe functional problems related to disability, and a large proportion of these persons will require Special Care Dentistry at some point in their lifetime. It is estimated that 90% of people requiring Special Care Dentistry should be able to access treatment in a local, primary care setting. Provision of such primary care is only possible through the education and training of dentists. The literature suggests that it is vital for the dental team to develop the necessary skills and gain experience treating people with special needs in order to ensure access to the provision of oral health care. Education in Special Care Dentistry worldwide might be improved by the development of a recognised academic and clinical discipline and by providing international curricula guidelines based on the International Classification of Functioning, Disability and Health (ICF, WHO). This article aims to discuss the role and value of promoting and harmonising education in Special Care Dentistry as a means of reducing inequalities in oral health. © 2012 John Wiley & Sons A/S.

Neutrophil numbers and function (oxidative burst) were assessed in peripheral blood and oral samples before and after prolonged exercise. Blood neutrophil count increased (∼3.5-fold, P < 0.001) and function decreased (30% ± 19% decrease, P = 0.005) postexercise. Oral neutrophil count (P = 0.392) and function (P = 0.334) were unchanged. Agreement between oral and blood neutrophil function responses to exercise was poor. These findings highlight the importance of studying neutrophils within various compartments/sample types.

Introduction for the special issue on recent advances in drug delivery across tissue barriers.

PubMed

Mrsny, Randall J; Brayden, David J

2016-01-01

This special issue of Tissue Barriers contains a series of reviews with the common theme of how biological barriers established at epithelial tissues limit the uptake of macromolecular therapeutics. By improving our functional understanding of these barriers, the majority of the authors have highlighted potential strategies that might be applied to the non-invasive delivery of biopharmaceuticals that would otherwise require an injection format for administration. Half of the articles focus on the potential of particular technologies to assist oral delivery of peptides, proteins and other macromolecules. These include use of prodrug chemistry to improve molecule stability and permeability, and the related potential for oral delivery of poorly permeable agents by cell-penetrating peptides and dendrimers. Safety aspects of intestinal permeation enhancers are discussed, along with the more recent foray into drug-device combinations as represented by intestinal microneedles and externally-applied ultrasound. Other articles highlight the crossover between food research and oral delivery based on nanoparticle technology, while the final one provides a fascinating interpretation of the physiological problems associated with subcutaneous insulin delivery and how inefficient it is at targeting the liver.

Including carrier-mediated transport in oral uptake prediction of nutrients and pharmaceuticals in humans.

2014-11-01

Most toxicokinetic models consider passive diffusion as the only mechanism when modeling the oral uptake of chemicals. However, the overall uptake of nutrients and xenobiotics, such as pharmaceuticals and environmental pollutants, can be increased by influx transport proteins. We incorporated carrier-mediated transport into a one-compartment toxicokinetic model originally developed for passive diffusion only. The predictions were compared with measured oral uptake efficiencies of nutrients and pharmaceuticals, i.e. the fraction of the chemical reaching systemic circulation. Including carrier-mediated uptake improved model predictions for hydrophilic nutrients (RMSE=10% vs. 56%, Coefficient of Efficiency CoE=0.5 vs. -9.6) and for pharmaceuticals (RMSE=21% vs. 28% and CoE=-0.4 vs. -1.1). However, the negative CoE for pharmaceuticals indicates that further improvements are needed. Most important in this respect is a more accurate estimation of vMAX and KM as well as the determination of the amount of expressed and functional transport proteins both in vivo and in vitro.

Genead, Mohamed A; Fishman, Gerald A; Lindeman, Martin

2009-12-01

To report a successfully treated case of acquired night blindness associated with fundus white spots secondary to vitamin A deficiency. An ocular examination, electrophysiologic testing, as well as visual field and OCT examinations were obtained on a 61-year-old man with vitamin A deficiency who had previously undergone gastric bypass surgery. The patient had a re-evaluation after treatment with high doses of oral vitamin A. The patient was observed to have numerous white spots in the retina of each eye. Best-corrected visual acuity was initially 20/80 in each eye, which improved to 20/40-1 OU after oral vitamin A therapy for 2 months. Full field electroretinogram (ERG) testing, showed non-detectable rod function and a 34 and 41% reduction for 32-Hz flicker and single flash cone responses, respectively, below the lower limits of normal. Both rod and cone functions markedly improved after initiation of vitamin A therapy. Vitamin A deficiency needs to be considered in a patient with white spots of the retina in the presence of poor night vision.

SUMMARY The effects of an oral fish oil treatment regimen on sensorimotor, blood-brain barrier, and biochemical outcomes of traumatic brain injury (TBI) were investigated in a juvenile rat model. Seventeen-day old Long-Evans rats were given a 15 mL/kg fish oil (2.01 g/kg EPA, 1.34 g/kg DHA) or soybean oil dose via oral gavage 30 minutes prior to being subjected to a controlled cortical impact injury or sham surgery, followed by daily doses for seven days. Fish oil treatment resulted in less severe hindlimb deficits after TBI as assessed with the beam walk test, decreased cerebral IgG infiltration, and decreased TBI-induced expression of the Mmp9h gene one day after injury. These results indicate that fish oil improved functional outcome after TBI resulting, at least in part from decreased disruption of the blood-brain barrier through a mechanism that includes attenuation of TBI-induced expression of Mmp9.

PURPOSE OF THE STUDY To determine whether pioglitazone will improve menstrual cyclicity in a fetal programming model for polycystic ovary syndrome. BASIC PROCEDURES Eight prenatally androgenized (PA) and 5 control female rhesus monkeys of similar age, body weight and body mass index received an oral placebo daily for 6–7 months followed, after at least 90 days, by daily oral dosing with pioglitazone (3mg/kg) for an additional 6–7 months. Blood was sampled thrice weekly to monitor ovulatory function, and a variety of endocrine challenges were performed to quantify changes in ovarian, gonadotropin and glucoregulatory function. MOST IMPORTANT FINDINGS Pioglitazone normalized menstrual cycles in 5 out of 8 (62%) PA females (pioglitazone responsive; PioRESP). Pioglitazone increased serum 17α-hydroxyprogesterone responses to an hCG injection in PioRESP PA females, while diminishing serum progesterone, and increasing DHEA and estradiol responses to hCG in PioRESP PA and all normal females. PRINCIPAL CONCLUSIONS Insulin resistance plays a mechanistic role in maintaining anovulation in a majority of PA female monkeys. PMID:17306503

The aim of this study was to evaluate the benefit of oral ubiquinol-10 supplementation in CFS patients using an open-label study and a randomized, double-blinded, placebo-controlled (RCT) study. Twenty patients with CFS were randomly enrolled in an 8-week open-label oral ubiquinol-10 (150 mg ubiquinol-10/day) study. The patients and the attending physicians were not blinded to the supplementation. Forty-three patients with CFS were randomly assigned to receive either ubiquinol-10 (150 mg/day) or placebo every day for 12 weeks. The patients and the attending physicians were blinded to the supplementation, and a total of 31 patients (N = 17 in the ubiquinol group and 14 in the placebo group) completed the study. The beneficial effects of ubiquinol-10 were observed in the open-label study we conducted prior to the RCT. The RCT results suggest that supplementation with ubiquinol-10 for 12 weeks is effective for improving several CFS symptoms. © 2016 BioFactors, 42(4):431-440, 2016. © 2016 International Union of Biochemistry and Molecular Biology.

To evaluate a brief oral health promotion intervention delivered in schools by a primary care dental practice, aimed at changing oral health care knowledge and oral health-related behaviors in children. Cohort study with pretest-posttest design. Three primary schools. One hundred and fifty children (aged 9-12 years). Children received a 60-minute theory-driven classroom-based interactive educational session delivered by a dental care professional and received take-home literature on oral health. All children completed a questionnaire on oral health-related knowledge and self-reported oral health-related behaviors before, immediately after, and 6 weeks following the intervention. Children's dental knowledge significantly improved following the intervention, with improvement evident at immediate follow-up and maintained 6 weeks later. Significantly more children reported using dental floss 6 weeks after the intervention compared with baseline. No significant differences were detected in toothbrushing or dietary behaviors. School-based preventative oral health education delivered by primary care dental practices can generate short-term improvements in children's knowledge of oral health and some aspects of oral hygiene behavior. Future research should engage parents/carers and include objective clinical and behavioral outcomes in controlled study designs. © 2014 Society for Public Health Education.

A Pluronic-functionalized silica-lipid hybrid (Plu-SLH) microparticle system for the oral delivery of poorly water-soluble, weak base drugs is reported for the first time. A highly effective Plu-SLH microparticle system was composed of Labrasol as the lipid phase, Pluronic F127 as the polymeric precipitation inhibitor (PPI), and silica nanoparticles as the solid carrier. For the model drug cinnarizine (CIN), the Plu-SLH delivery system was shown to offer significant biopharmaceutical advantages in comparison with unformulated drug and drug in the silica-lipid hybrid (SLH) system. In vitro two-phase dissolution studies illustrated significantly reduced pH provoked CIN precipitation and an 8- to 14-fold improvement in the extent of dissolution in intestinal conditions. In addition, under simulated intestinal digesting conditions, the Plu-SLH provided approximately three times more drug solubilization than the SLH. Oral administration in rats resulted in superior bioavailability for Plu-SLH microparticles, i.e., 1.6- and 2.1-fold greater than the SLH and the unformulated CIN, respectively. A physical mixture of Pluronic and SLH (Plu&SLH), having the same composition as Plu-SLH, was also evaluated, but showed no significant increase in CIN absorption when compared to unmodified CIN or SLH. This work represents the first study where different methods of incorporating PPI to formulate solid-state lipid-based formulations were compared for the impact on the biopharmaceutical performance. The data suggest that the novel physicochemical properties and structure of the fabricated Plu-SLH microparticle delivery system play an important role in facilitating the synergistic advantage of Labrasol and Pluronic F127 in preventing drug precipitation, and the Plu-SLH provides efficient oral delivery of poorly water-soluble weak bases.

Irritant contact dermatitis (ICD) is an inflammatory skin disease triggered by exposure to a chemical that is toxic or irritating to the skin. A major characteristic of chronic ICD is an inflammatory dry-skin condition with associated itching. Although glucosylceramide (GlcCer) is known to improve the skin barrier function, its mechanism of action is unknown. Using a mouse model of oxazolone-induced chronic ICD, this study investigated the effects of oral administration of GlcCer on inflammatory dry skin. Chronic ICD was induced by repeated application of oxazolone in mice. GlcCer was orally administered once daily throughout the elicitation phase. The beneficial efficacy of GlcCer on cutaneous inflammation was evaluated by assessing ear thickness, lymph node weight, histological findings, and mRNA expression of pro-inflammatory cytokines such as IL-1β and IL-6. Additionally, parameters of the itch-associated response, including scratching behavior, water content of the skin, and aquaporin-3 levels in the lesional ear, were measured. Oral GlcCer administration significantly suppressed mRNA expression of the pro-inflammatory cytokines IL-1β and IL-6. GlcCer also suppressed ear swelling, lymph node weight gains, and infiltration of leukocytes and mast cells in ICD mice. In oxazolone-induced ICD mice, GlcCer significantly inhibited irritant-related scratching behavior and dehydration of the stratum corneum, and decreased aquaporin-3 expression. Our results indicate that GlcCer suppressed inflammation not only by inhibiting cytokine production but also by repairing the skin barrier function, suggesting a potential beneficial role for GlcCer in the improvement of chronic ICD.

Children with autism have heightened risk of developing oral health problems. Interventions targeting at-home oral hygiene habits may be the most effective means of improving oral hygiene outcomes in this population. This randomized control trial examined the effectiveness of a 3-week video-modeling brushing intervention delivered to patients over the internet. Eighteen children with autism were assigned to an Intervention or Control video condition. Links to videos were delivered via email twice daily. Blind clinical examiners provided plaque index ratings at baseline, midpoint, and endpoint. Results show oral hygiene improvements in both groups, with larger effect sizes in the Intervention condition. The findings provide preliminary support for the use of internet-based interventions to improve oral hygiene for children with autism.

To compare the efficacy difference in the treatment of shoulder pain in post-stroke shoulder-hand syndrome among floating acupuncture, oral administration of western medicine and local fumigation of Chinese herbs. Ninety cases of post-stroke shoulder-hand syndrome (stage I) were randomized into a floating acupuncture group, a western medicine group and a local Chinese herbs fumigation group, 30 cases in each one. In the floating acupuncture group, two obvious tender points were detected on the shoulder and the site 80-100 mm inferior to each tender point was taken as the inserting point and stimulated with floating needling technique. In the western medicine group, mobic 7.5 mg was prescribed for oral administration. In the local Chinese herbs fumigation group, the formula for activating blood circulation and relaxing tendon was used for local fumigation. All the patients in three groups received rehabilitation training. The floating acupuncture, oral administration of western medicine, local Chinese herbs fumigation and rehabilitation training were given once a day respectively in corresponding group and the cases were observed for 1 month. The visual analogue scale (VAS) and Takagishi shoulder joint function assessment were adopted to evaluate the dynamic change of the patients with shoulder pain before and after treatment in three groups. The modified Barthel index was used to evaluate the dynamic change of daily life activity of the patients in three groups. With floating acupuncture, shoulder pain was relieved and the daily life activity was improved in the patients with post-stroke shoulder-hand syndrome, which was superior to the oral administration of western medicine and local Chinese herbs fumigation (P < 0.01). With local Chinese herbs fumigation, the improvement of shoulder pain was superior to the oral administration of western medicine. The difference in the improvement of daily life activity was not significant statistically between the local Chinese herbs fumigation and oral administration of western medicine, the efficacy was similar between these two therapies (P > 0.05). The floating acupuncture relieves shoulder pain of the patients with post-stroke shoulder-hand syndrome promptly and effectively, and the effects on shoulder pain and the improvements of daily life activity are superior to that of the oral administration of western medicine and local Chinese herbs fumigation.

What is the central question of this study? Angiotensin-(1-7) decreases cerebral infarct volume and improves neurological function when delivered centrally before and during ischaemic stroke. Here, we assessed the neuroprotective effects of angiotensin-(1-7) when delivered orally post-stroke. What is the main finding and its importance? We show that oral delivery of angiotensin-(1-7) attenuates cerebral damage induced by middle cerebral artery occlusion in rats, without affecting blood pressure or cerebral blood flow. Importantly, these treatments begin post-stroke at times coincident with the treatment window for tissue plasminogen activator, providing supporting evidence for clinical translation of this new therapeutic strategy. As a target for stroke therapies, the angiotensin-converting enzyme 2-angiotensin-(1-7)-Mas [ACE2/Ang-(1-7)/Mas] axis of the renin-angiotensin system can be activated chronically to induce neuroprotective effects, in opposition to the deleterious effects of angiotensin II via its type 1 receptor. However, more clinically relevant treatment protocols with Ang-(1-7) that involve its systemic administration beginning after the onset of ischaemia have not been tested. In this study, we tested systemic post-stroke treatments using a molecule where Ang-(1-7) is included within hydroxypropyl-β-cyclodextrin [HPβCD-Ang-(1-7)] as an orally bioavailable treatment. In three separate protocols, HPβCD-Ang-(1-7) was administered orally to Sprague-Dawley rats after induction of ischaemic stroke by endothelin-1-induced middle cerebral artery occlusion: (i) to assess its effects on cerebral damage and behavioural deficits; (ii) to determine its effects on cardiovascular parameters; and (iii) to determine whether it altered cerebral blood flow. The results indicate that post-stroke oral administration of HPβCD-Ang-(1-7) resulted in 25% reductions in cerebral infarct volumes and improvement in neurological functions (P < 0.05), without inducing any alterations in blood pressure, heart rate or cerebral blood flow. In conclusion, Ang-(1-7) treatment using an oral formulation after the onset of ischaemia induces significant neuroprotection in stroke and might represent a viable approach for taking advantage of the protective ACE2/Ang-(1-7)/Mas axis in this disease. © 2018 The Authors.

Purpose Oral conditions are established complications in terminally-ill cancer patients. Yet despite significant morbidity, the characteristics and impact of oral conditions in these patients are poorly documented. The study objective was to characterize oral conditions in terminally-ill cancer patients to determine the presence, severity, and the functional and social impact of these oral conditions. Methods This was an observational clinical study including terminally-ill cancer patients (2.5–3 week life expectancy). Data were obtained via the Oral Problems Scale (OPS) that measures the presence of subjective xerostomia, orofacial pain, taste change, and the functional/social impact of oral conditions and a demographic questionnaire. A standardized oral examination was used to assess objective salivary hypofunction, fungal infection, mucosal erythema, and ulceration. Regression analysis and t test investigated the associations between measures. Results Of 104 participants, most were ≥50 years of age, female, and high-school educated; 45% were African American, 43% Caucasian, and 37% married. Oral conditions frequencies were: salivary hypofunction (98%), mucosal erythema (50%), ulceration (20%), fungal infection (36%), and other oral problems (46%). Xerostomia, taste change, and orofacial pain all had significant functional impact; p<.001, p=.042 and p<.001, respectively. Orofacial pain also had a significant social impact (p<.001). Patients with oral ulcerations had significantly more orofacial pain with a social impact than patients without ulcers (p=.003). Erythema was significantly associated with fungal infection and with mucosal ulceration (p<.001). Conclusions Oral conditions significantly affect functional and social activities in terminally-ill cancer patients. Identification and management of oral conditions in these patients should therefore be an important clinical consideration. PMID:24232310

This study aims to analyse the relationship between seven health practices, oral health behaviors, and oral health status in community dwelling elderly Thai. The subjects were 612 elderly people (mean age = 68.8 ± 5.9 years). Questionnaires survey about sociodemographics, self-reported seven health practices and oral health behaviors were conducted by trained interviewers. Oral examinations investigated the number of teeth present, decayed teeth, periodontal status and functional tooth units (FTUs). Oral malodor was assessed by Organoleptic Test, and unstimulated saliva was collected for 5 min. Five health practices (smoking, drinking, physical activity, breakfast and weight maintenance) were significantly related with oral health behaviors. ancova analysis demonstrated the following significant associations: (i) smoking behavior with number of teeth present, number of FTUs, decayed teeth, periodontal disease, oral malodor and salivary flow rate, (ii) drinking alcohol behavior with number of teeth present, number of FTUs, periodontal disease, oral malodor and salivary flow rate, (iii) eating breakfast behavior with periodontal disease, oral malodor and salivary flow rate, (iv) eating between-meal snack with number of teeth present, number of FTUs, decayed teeth and periodontal disease, (v) maintaining weight with number of teeth present, number of FTUs, periodontal disease and oral malodor, (vi) sleeping with number of teeth present, number of FTUs, periodontal disease, oral malodor and salivary flow rate, (vii) physical activity with periodontal disease and salivary flow rate. Good health practices were related with good oral health behaviors. Moreover, general health practices were associated with the clinical oral health status such as number of teeth present, decayed teeth, FTUs, periodontal disease, oral malodor and salivary flow rate. The elderly with good general health practices were considered to have good oral health status. Improving general health habits are suggested to lead to better oral health for the elderly, and vice versa. © 2012 John Wiley & Sons A/S and The Gerodontology Society.

A 53-year-old institutionalized male patient with a history of postoperative bilateral hypoglossal nerve injury was admitted for treatment of dysphagia. He experienced dysphagia involving oral cavity-to-pharynx bolus transportation because of restricted tongue movement and was treated with a palatal augmentation prosthesis (PAP), which resulted in improved bolus transportation, pharyngeal swallowing pressure, and clearance of oral and pharyngeal residue. The mean pharyngeal swallowing pressure at tongue base with the PAP (145.5±7.5mmHg) was significantly greater than that observed immediately after removal of the PAP (118.3±10.1mmHg; p<0.05; independent t-test). Dysphagia rehabilitation with the PAP was continued. Approximately 1 month after PAP application, the patient could orally consume three meals, with the exception of foods particularly difficult to swallow. The supporting contact between the tongue and palate enabled by the PAP resulted in improvement of bolus transportation, which is the most important effect of a PAP. The increase in pharyngeal swallowing pressure at the tongue base because of PAP-enabled tongue-palate contact might play an important role in this improvement. Since a PAP augments the volume of the palate, it enables easy contact between the tongue and palate, resulting in the formation of an anchor point for tongue movement during swallowing. Thus, application of a PAP increases the tongue force, especially that of the basal tongue. A palatal augmentation prosthesis helps improve pharyngeal swallowing pressure at the basal tongue region and might contribute to the decrease of oral as well as pharyngeal residue.

Background Neuromuscular electrical stimulation with muscle contraction, administered through the skin of the neck, improves a patient’s swallowing ability. However, the beneficial effects of transcutaneous electrical sensory stimulation (TESS), without muscle contraction, are controversial. We investigated the effect of TESS, using interferential current, in patients undergoing dysphagia rehabilitation. Methods This double-blind, randomized controlled trial involved 43 patients who were prescribed in-hospital dysphagia rehabilitation for ≥3 weeks. Patients were randomly assigned to the sensory stimulation (SS) or sham groups; all received usual rehabilitative care plus 2 weeks of SS or sham intervention. Outcome measures included cough latency times against a 1% citric acid mist, functional oral intake scale (FOIS) scores, and oral nutritional intake – each determined after the second and third week following treatment initiation. Results Mean patient age was 84.3±7.5 years; 58% were women. The SS and sham groups had similar baseline characteristics. Changes in cough latency time at 2 weeks (−14.1±14.0 vs −5.2±14.2 s, p=0.047) and oral nutrition intake at 3 weeks (437±575 vs 138±315 kcal/day, p=0.042) improved more in the SS group than in the sham group. Changes in cough frequency and FOIS scores indicated better outcomes in the SS group, based on substantial effect sizes. Conclusion TESS, using interferential current through the neck, improved airway defense and nutrition in patients suffering from dysphagia. Further large-scale studies are needed to confirm the technique’s effect on swallowing ability. PMID:29158670

To assess the interaction between insulin resistance and endothelial function and the optimal treatment strategy addressing cardiovascular risk in polycystic ovary syndrome. Randomized controlled trial. Controlled clinical study. Overweight age- and body mass index-matched women with polycystic ovary syndrome. Six months metformin (1 g two times per day, n = 36) or oral contraceptive pill (OCP) (35 microg ethinyl E(2)-2 mg cytoproterone acetate, n = 30). Fasting and oral glucose tolerance test glucose and insulin levels, endothelial function (flow-mediated dilation, asymmetric dimethylarginine, plasminogen activator inhibitor-1, von Willebrand factor), inflammatory markers (high-sensitivity C-reactive protein), lipids, and hyperandrogenism. The OCP increased levels of glucose and insulin on oral glucose tolerance test, high-sensitivity C-reactive protein, triglycerides, and sex-hormone binding globulin and decreased levels of low-density lipoprotein cholesterol and T. Metformin decreased levels of fasting insulin, oral glucose tolerance test insulin, high-density lipoprotein cholesterol, and high-sensitivity C-reactive protein. Flow-mediated dilation increased only with metformin (+2.2% +/- 4.8%), whereas asymmetric dimethylarginine decreased equivalently for OCP and metformin (-0.3 +/- 0.1 vs. -0.1 +/- 0.1 mmol/L). Greater decreases in plasminogen activator inhibitor-1 occurred for the OCP than for metformin (-1.8 +/- 1.6 vs. -0.7 +/- 1.7 U/mL). In polycystic ovary syndrome, metformin improves insulin resistance, inflammatory markers, and endothelial function. The OCP worsens insulin resistance and glucose homeostasis, inflammatory markers, and triglycerides and has neutral or positive endothelial effects. The effect of the OCP on cardiovascular risk in polycystic ovary syndrome is unclear. Copyright 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

Current training provision and training needs in oral health for UK general practice trainees: survey of General Practitioner Training Programme Directors.

2016-05-11

In the UK the incidence of oral cancers has risen by a third in the last decade, and there have been minimal improvements in survival rates. Moreover, a significant proportion of the population no longer access dental health services regularly, instead presenting their oral health concerns to their General Medical Practitioner. Therefore, General Practitioners (GP) have an important role in the diagnosis of oral health pathologies and the earlier detection of oral cancers. This study aims to understand the current provision of training in oral health and cancer for GP trainees and to identify how unmet training needs could be met. A cross-sectional survey of GP Training Programme Directors using an online questionnaire asking about current oral health education training (hospital placements and structured teaching), the competencies covered with trainees and ways to improve oral health training. Quantitative data were analysed using descriptive statistics and content analysis was undertaken of free text responses. We obtained responses from 132 GP Training Programme Directors (GPTPDs), from 13 of the 16 UK medical deaneries surveyed. The majority of respondents (71.2%) indicated that their programmes did not provide any structured oral health training to GP trainees and that ≤ 10% of their trainees were undertaking hospital posts relevant to oral health. GPTPDs were of the view that the quality of oral health training was poor, relative to the specified competencies, and that teaching on clinical presentations of 'normal' oral anatomy was particularly poor. It was envisaged that oral health training could be improved by access to specialist tutors, e-learning programmes and problem-based-learning sessions. Respondents highlighted the need for training sessions to be relevant to GPs. Barriers to improving training in oral health were time constraints, competing priorities and reluctance to taking on the workload of dentists. This UK-wide survey has identified important gaps in the training of GP trainees in relation to oral health care and cancer detection. Addressing these knowledge and skill gaps, particularly in the identification of oral cancers, will help to improve oral health and, more importantly, the timely diagnosis of oral cancer.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We performed a comprehensive review of phase 3 studies of tofacitinib 5 mg twice daily (BID) (approved dose in many countries) in patients with moderate to severe RA and inadequate response to prior disease-modifying antirheumatic drugs. A search of PubMed and ClinicalTrials.gov identified 5 studies: ORAL Solo (NCT00814307), ORAL Sync (NCT00856544), ORAL Standard (included adalimumab 40 mg once every 2 weeks; NCT00853385), ORAL Scan (NCT00847613), and ORAL Step (NCT00960440). Efficacy and safety data for tofacitinib 5 mg BID, placebo, and adalimumab were analyzed. Across the 5 studies, 1216 patients received tofacitinib 5 mg BID, 681 received placebo, and 204 received adalimumab. At month 3, tofacitinib demonstrated significantly higher 20%, 50%, and 70% improvement in American College of Rheumatology response criteria (ACR20, ACR50, and ACR70, respectively) response rates, greater improvement in Health Assessment Questionnaire-Disability Index, and a higher proportion of Disease Activity Score-defined remission than placebo. Frequencies of adverse events (AEs), serious AEs, and discontinuations due to AEs were similar for tofacitinib and placebo at month 3; serious infection events were more frequent for tofacitinib. In ORAL Standard, although not powered for formal comparisons, tofacitinib and adalimumab had numerically similar efficacy and AEs; serious AEs and serious infection events were more frequent with tofacitinib. Tofacitinib 5 mg BID reduced RA signs and symptoms and improved physical function versus placebo in patients with inadequate response to prior disease-modifying antirheumatic drugs. Tofacitinib 5 mg BID had a consistent, manageable safety profile across studies, with no new safety signals identified.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

2015-06-01

Fibroblasts are cells of mesenchymal origin. They are responsible for the production of most extracellular matrix in connective tissues and are essential for wound healing and repair. In recent years, it has become clear that fibroblasts from different tissues have various distinct traits. Moreover, wounds in the oral cavity heal under very special environmental conditions compared with skin wounds. Here, we reviewed the current literature on the various interconnected functions of gingival and mucoperiosteal fibroblasts during the repair of oral wounds. The MEDLINE database was searched with the following terms: (gingival OR mucoperiosteal) AND fibroblast AND (wound healing OR repair). The data gathered were used to compare oral fibroblasts with fibroblasts from other tissues in terms of their regulation and function during wound healing. Specifically, we sought answers to the following questions: (i) what is the role of oral fibroblasts in the inflammatory response in acute wounds; (ii) how do growth factors control the function of oral fibroblasts during wound healing; (iii) how do oral fibroblasts produce, remodel and interact with extracellular matrix in healing wounds; (iv) how do oral fibroblasts respond to mechanical stress; and (v) how does aging affect the fetal-like responses and functions of oral fibroblasts? The current state of research indicates that oral fibroblasts possess unique characteristics and tightly controlled specific functions in wound healing and repair. This information is essential for developing new strategies to control the intraoral wound-healing processes of the individual patient. © 2015 John Wiley & Sons A/S.

To investigate the challenges of providing oral health advice/treatment as experienced by non-dental primary care providers in rural and remote areas with no resident dentist, and their views on ways in which oral health and oral health services could be improved for their communities. Qualitative study with semistructured interviews and thematic analysis. Four remote communities in outback Queensland, Australia. 35 primary care providers who had experience in providing oral health advice to patients and four dental care providers who had provided oral health services to patients from the four communities. In the absence of a resident dentist, rural and remote residents did present to non-dental primary care providers with oral health problems such as toothache, abscess, oral/gum infection and sore mouth for treatment and advice. Themes emerged from the interview data around communication challenges and strategies to improve oral health. Although, non-dental care providers commonly advised patients to see a dentist, they rarely communicated with the dentist in the nearest regional town. Participants proposed that oral health could be improved by: enabling access to dental practitioners, educating communities on preventive oral healthcare, and building the skills and knowledge base of non-dental primary care providers in the field of oral health. Prevention is a cornerstone to better oral health in rural and remote communities as well as in more urbanised communities. Strategies to improve the provision of dental services by either visiting or resident dental practitioners should include scope to provide community-based oral health promotion activities, and to engage more closely with other primary care service providers in these small communities.

This single-blind study compared the efficacy of oral forskolin versus inhaled beclomethasone for mild or moderately persistent adult asthma. Patients were randomly assigned to receive forskolin (one 10-mg capsule orally per day; n = 30) or beclomethasone (two 50 microg inhalations every 12 h; n = 30) for 2 months. No statistically significant improvement occurred in any lung function parameter in the forskolin-treated patients. Subjects in the beclomethasone-treated group presented a slight but statistically significant improvement in percentage forced expiratory volume in 1 s (FEV(1)), percentage forced expiratory flow in the middle (25 - 75%) expiratory phase (FEF(25 - 75%)) and percentage forced vital capacity (FVC) after 2 months of treatment, though the improvement in absolute values for FEV(1), FEF(25 - 75%), FVC and FEV(1):FVC did not reach statistical significance. There was no statistically significant difference between the forskolin and beclomethasone treatment groups for any lung function parameter at baseline or after treatment. None of the beclomethasone-treated patients had an asthma attack and one forskolin-treated patient had a mild asthma attack during the 2-month study period. More studies are needed in adult asthma patients to confirm whether forskolin may be a useful preventive treatment for mild or moderately persistent adult asthma.

Severe pulmonary hypertension is a progressive disease which leads to limitations of functional status and poor survival. We evaluated efficacy and safety of a short (3 months) and a long term (12 months) sildenafil treatment in patients with severe pulmonary hypertension. We treated 12 patients with pulmonary hypertension with oral sildenafil. Patients were followed at three time points, at baseline, and after 3 and 12 months of treatment. Primary end point was improvement in functional exercise capacity assesed by 6-minute walk test, and secondary end points were changes in right ventricle hemodynamics. We found significant improvement in 6-minute walk test distance from 357 +/- 193 m at baseline to 431 +/- 179 m after three months and further improvement to 501 +/- 159 m after 12 months (p < 0.01); decrease in right ventricule pressure from 107 +/- 42 mmHg at baseline to 87 +/- 32 mmHg after 12 months (p < 0.01); and, decrease in right ventricule diameter from 3.2 +/- 1.1 cm to 2.76 +/- 0.86 cm after twelve months (p < 0.01). Drug-related adverse events were mild and transient in our group of patients. Long-term (12 months) sildenafil treatment is effective and safe in our patients with idiopathic and chronic thrombo-embolic pulmonary hypertension.

Myo-inositol and D-chiro-inositol are capable of improving the ovarian function and metabolism of polycystic ovary syndrome (PCOS) patients. The aim of this work is to compare the effects of myo-inositol and D-chiro-inositol in PCOS. We enrolled 50 patients, with homogeneous bio-physical features, affected by PCOS and menstrual irregularities, and we randomly divided them into two groups: 25 were treated with 4 g of myo-inositol/die plus 400 mcg of folic acid/die orally for six months, 25 with 1 g of D-chiro-inositol/die plus 400 mcg of folic acid/die orally for six months. We analyzed in both groups pre-treatment and post-treatment BMI, systolic and diastolic blood pressure, Ferriman-Gallwey score, Cremoncini score, serum LH, LH/FSH ratio, total and free testosterone, dehydroepiandrosterone sulfate (DHEA-S), Δ-4-androstenedione, SHBG, prolactin, glucose/immunoreactive insulin (IRI) ratio, homeostatic model assessment (HOMA) index, and the resumption of regular menstrual cycles. Both the isoforms of inositol were effective in improving ovarian function and metabolism in patients with PCOS, although myo-inositol showed the most marked effect on the metabolic profile, whereas D-chiro-inositol reduced hyperandrogenism better.

Mammalian target of rapamycin (mTOR) signalling is central in the activation of hepatic stellate cells (HSCs), the key source of extracellular matrix (ECM) in fibrotic liver. We tested the therapeutic potential of the mTOR inhibitor rapamycin in advanced cirrhosis. Cirrhosis was induced by bile duct-ligation (BDL) or thioacetamide injections (TAA). Rats received oral rapamycin (0.5 mg/kg/day) for either 14 or 28 days. Untreated BDL and TAA-rats served as controls. Liver function was quantified by aminopyrine breath test. ECM and ECM-producing cells were quantified by morphometry. MMP-2 activity was measured by zymography. mRNA expression of procollagen-alpha1, transforming growth factor-beta1 (TGF-beta1) and beta2 was quantified by RT-PCR. Fourteen days of rapamycin improved liver function. Accumulation of ECM was decreased together with numbers of activated HSCs and MMP-2 activity in both animal models. TGF-beta1 mRNA was downregulated in TAA, TGF-beta2 mRNA was downregulated in BDL. 28 days of rapamycin treatment entailed a survival advantage of long-term treated BDL-rats. Low-dose rapamycin treatment is effectively antifibrotic and attenuates disease progression in advanced fibrosis. Our results warrant the clinical evaluation of rapamycin as an antifibrotic drug.

To investigate the therapeutic effect of the compound Danshen dripping pill combined with laser acupoint irradiation on early diabetic retinopathy, 19 patients with early diabetic retinopathy were randomly divided into a treatment group and a control group. The TaiYang, YangBai, YuYao and ZanZhu acupoints of patients in the treatment group were irradiated with a semiconductor laser combined with the oral compound Danshen dropping pills, while those in the control group only used the oral compound Danshen dropping pills. The indicators of vision, mean defect of light sensitivity in the visual field, renal function and fasting blood glucose, were examined to evaluate the efficacy. After treatment, the above indicators of patients in the two groups were significantly improved and there was a significant difference between the two groups. This showed that the compound Danshen dripping pills combined with the laser acupoint irradiation can improve the ischemic and anoxic state of early diabetic retinopathy and improve the visual field.

The effects of two food materials, γ-aminobutyric acid (GABA) produced by natural fermentation and Apocynum venetum leaf extract (AVLE), on the improvement of sleep were investigated in humans. The electroencephalogram (EEG) test revealed that oral administration of GABA (100 mg) and AVLE (50 mg) had beneficial effects on sleep. GABA shortened sleep latency by 5.3 min and AVLE increased non-rapid eye movement (REM) sleep time by 7.6%. Simultaneous intake of GABA and AVLE shortened sleep latency by 4.3 min and increased non-REM sleep time by 5.1%. The result of questionnaires showed that GABA and AVLE enabled subjects to realize the effects on sleep. These results mean that GABA can help people to fall asleep quickly, AVLE induces deep sleep, and they function complementarily with simultaneous intake. Since both GABA and AVLE are materials of foods and have been ingested for a long time, they can be regarded as safe and appropriate for daily intake in order to improve the quality of sleep.

This randomized, controlled, double-blind clinical study in parallel groups evaluated the safety and efficacy of an oral combination diclofenac-cholestyramine, nucleotides (uridine and cytidine) and vitamin B12 versus the oral combination of nucleotides and vitamin B12 in the treatment of acute, non-traumatic pain. Subjects received twice-daily, 10-day oral administration of diclofenac-cholestyramine + uridine + cytidine + vitamin B12 (Group DN, n=40) or uridine + cytidine + vitamin B12 (Group NB, n=41). The primary study endpoint was the number of subjects with VAS reduction of >30mm after 10 days of treatment. Secondary endpoints included the number of patients with improvement >5 points in the Patient Functionality Questionnaire after 10 days of treatment, and the number of subjects presenting adverse events. Treatment with the combination of diclofenac-cholestyramine, nucleotides and Vitamin B12 resulted in a higher number of subjects with VAS score reductions >30mm after 10 days of treatment (87.5% subjects) than in the control group administered nucleotides and Vitamin B12 (51.23% of subjects), (p>0.0006). A significantly higher number of subjects in the DN group (80%) had a score reduction of >5 points in the Patient Functionality Questionnaire at after 10 days of treatment compared to Group NB (29.3%), (p<0.001). The number of subjects presenting AEs did not vary significantly between treatment groups (p=0.587). The combination of diclofenac-cholestyramine with uridine, cytidine and vitamin B12 was well-tolerated over a 10-day treatment period. The combination reduced pain and improved functionality among subjects presenting acute, non-traumatic pain in the lower back, hips, and neck.

The modulating effect of estrogen on glucose homeostasis remains a controversial issue at present. In this study, we sought to determine the beneficial effect of 17{beta}-estradiol (E{sub 2}) on hyperglycemia and islet {beta}-cell functions in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were injected i.p. with STZ to induce a relatively mild diabetic condition. The rats were then treated with E{sub 2} orally at 500 {mu}g/kg body weight/day for 15 days to evaluate the modulating effect on hyperglycemia, insulin secretion, and islet {beta}-cell proliferation. E{sub 2} administration for 10 days significantly lowered plasma glucose levels, increased plasma insulin levels, andmore » improved glucose tolerance by attenuating insulin response to oral glucose loading. These beneficial effects of E{sub 2} were accompanied by increases in islet number and volume, rate of islet cell proliferation, and the amount of insulin secreted. The growth-stimulatory effect of E{sub 2} on islet cells was linked to the functions of the estrogen receptor {alpha}. Notably, these protective effects of E{sub 2} on diabetic conditions were basically not observed when the STZ-treated rats had a more severe degree of islet damage and hyperglycemia. Taken together, we conclude that E{sub 2} can promote the regeneration of damaged pancreatic islets by stimulating {beta}-cell proliferation in diabetic rats, and this effect is accompanied by improvements in glucose tolerance and a decrease in plasma glucose levels. These findings suggest that oral administration of E{sub 2} may be beneficial in diabetic patients with an accelerated loss of islet {beta}-cells.« less

Protein malnutrition is both a cause and consequence of inflammation and related comorbidities for maintenance hemodialysis (MHD) patients. This study sought to determine if oral supplementation with soy or whey protein during dialysis treatment reduces inflammation and improves physical function and body composition in MHD patients. The design used in the study was randomized controlled trial, and the setting used was hemodialysis clinics in Champaign and Chicago, Illinois. Patients who received treatment ≥3 days/week, were ages ≥30 years did not have congestive heart failure or chronic obstructive pulmonary disease, and were receiving dialysis treatment for ≥3 months were eligible for inclusion. Patients were randomized to oral supplementation with a whey protein, soy protein, or placebo beverage. Patients (WHEY, n = 11; SOY, n = 12; CON, n = 15) consumed their assigned beverage before every dialysis session for 6 months. Body composition was measured by dual-energy x-ray absorptiometry, physical function by gait speed and shuttle walk test, and markers of inflammation (C-reactive protein and interleukin 6) using commercially available enzyme-linked immunosorbent assay kits before and after the 6-month intervention. Dietary intake was assessed by 24-hour dietary recalls. Six months of whey or soy supplementation significantly reduced predialysis interleukin 6 levels (P < .05 for both), whereas there was a trend for a reduction in C-reactive protein when both protein groups were combined (P = .062). Gait speed and shuttle walk test performance also significantly improved in the protein groups (P < .05 for both). No changes in body composition were observed. However, alkaline phosphatase, a marker of bone turnover, was significantly reduced in the protein groups. Intradialytic protein supplementation during a 6-month intervention reduced inflammation and improved physical function and represents an affordable intervention to improve the health of MHD patients.

Text messaging is useful for promoting numerous health-related behaviors. The Text2Floss Study examines the feasibility and utility of a 7-day text messaging intervention to improve oral health knowledge and behavior in mothers of young children. Mothers were recruited from a private practice and a community clinic. Of 156 mothers enrolled, 129 randomized into text (n = 60) and control groups (n = 69) completed the trial. Participants in the text group received text messages for 7 days, asking about flossing and presenting oral health information. Oral health behaviors and knowledge were surveyed pre- and post-intervention. At baseline, there were no differences between text and control group mothers in knowledge and behaviors (P > 0.10). Post-intervention, text group mothers flossed more (P = 0.01), had higher total (P = 0.0006) and specific (P < 0.05) knowledge, and tried to improve their child's oral health behaviors (P = 0.03) and decrease their soda and sugary snacks (P = 0.05) more than control mothers. Text messages were accepted and perceived as useful. Mothers receiving text messages improved their own oral health behaviors and knowledge as well as their behaviors regarding their children's oral health. Text messaging represents a viable method to improve oral health behaviors and knowledge. Its high acceptance may make it useful for preventing oral disease. © 2014 American Association of Public Health Dentistry.

Despite strong observational evidence for a beneficial role of oestrogen in cardiovascular disease, recent trial results suggest that hormone replacement therapy (HRT) may have adverse effects in menopausal women with established coronary heart disease. Isoflavones are oestrogen analogues found in plants with oestrogen-like properties and, because of a favourable side-effect profile, may be ideal alternatives to HRT with respect to cardiovascular benefits. Endothelial function is a marker of cardiovascular health. We aimed to determine the effect of isoflavones on endothelial function using the brachial artery reactivity test. Twenty-nine healthy menopausal women underwent entry and exit brachial artery reactivity testing following randomization to 2 weeks of an oral soy isoflavone concentrate containing 80 mg of soy isoflavones (Archer Daniel Midland Inc., IL, USA) or placebo. At study exit, there was no difference between placebo and isoflavone groups with respect to flow-mediated dilation (%FMD(max)), change (entry to exit) in %FMD(max) or response to nitroglycerine (%TNG). Subgroup analyses assessing lipid and oestrogen effects did not produce any significant results. These results suggest that short-term oral isoflavone supplements do not improve endothelial function in healthy menopausal women.

Children with a cleft in the soft palate have difficulties with speech, swallowing, and sucking. These patients are unable to separate the nasal from the oral cavity leading to air loss during speech. Although surgical repair ameliorates soft palate function by joining the clefted muscles of the soft palate, optimal function is often not achieved. The regeneration of muscles in the soft palate after surgery is hampered because of (1) their low intrinsic regenerative capacity, (2) the muscle properties related to clefting, and (3) the development of fibrosis. Adjuvant strategies based on tissue engineering may improve the outcome after surgery by approaching these specific issues. Therefore, this review will discuss myogenesis in the noncleft and cleft palate, the characteristics of soft palate muscles, and the process of muscle regeneration. Finally, novel therapeutic strategies based on tissue engineering to improve soft palate function after surgical repair are presented. PMID:22697475

Vitamin D may be a regulator of skeletal muscle function, although human trials investigating this hypothesis are limited to predominantly elderly populations. We aimed to assess the effect of oral vitamin D3 in healthy young males upon skeletal muscle function. Participants (n = 29) received an oral dose of 10,000 IU day(-1) vitamin D3 (VITD) or a visually identical placebo (PLB) for 3 months. Serum 25[OH]D and intact parathyroid hormone (iPTH) were measured at baseline and at week 4, 8 and 12. Muscle function was assessed in n = 22 participants by isokinetic dynamometry and percutaneous isometric electromyostimulation at baseline and at week 6 and 12. Baseline mean total serum 25[OH]D was 40 ± 17 and 41 ± 20 nmol L(-1) for PLB and VITD, respectively. VITD showed a significant improvement in total 25[OH]D at week 4 (150 ± 31 nmol L(-1)) that remained elevated throughout the trial (P < 0.005). Contrastingly, PLB showed a significant decrease in 25[OH]D at week 12 (25 ± 15 nmol L(-1)) compared with baseline. Despite marked increases in total serum 25[OH]D in VITD and a decrease in PLB, there were no significant changes in any of the muscle function outcome measures at week 6 or 12 for either group (P > 0.05). Elevating total serum 25[OH]D to concentrations > 120 nmol L(-1) has no effect on skeletal muscle function. We postulate that skeletal muscle function is only perturbed in conditions of severe deficiency (<12.5 nmol L(-1)).

Potential role of p21 Activated Kinase 1 (PAK1) in the invasion and motility of oral cancer cells.

Oral cancer malignancy consists of uncontrolled division of cells primarily in and around the floor of the oral cavity, gingiva, oropharynx, lower lip and base of the tongue. According to GLOBOCAN 2012 report, oral cancer is one of the most common cancers among males and females in India. Even though significant advancements have been made in the field of oral cancer treatment modalities, the overall prognosis for the patients has not improved in the past few decades and hence, this demands a new thrust for the identification of novel therapeutic targets in oral cancer. p21 Activated Kinases (PAKs) are potential therapeutic targets that are involved in numerous physiological functions. PAKs are serine-threonine kinases and they serve as important regulators of cytoskeletal dynamics and cell motility, transcription through MAP kinase cascades, death and survival signalling, and cell-cycle progression. Although PAKs are known to play crucial roles in cancer progression, the role and clinical significance of PAKs in oral cancer remains poorly understood. Our results suggest that PAK1 is over-expressed in oral cancer cell lines. Stimulation of Oral Squamous Cell Carcinoma (OSCC) cells with serum growth factors leads to PAK1 re-localization and might cause a profound cytoskeletal remodelling. PAK1 was also found to be involved in the invasion, migration and cytoskeletal remodelling of OSCC cells. Our study revealed that PAK1 may play a crucial role in the progression of OSCC. Studying the role of PAK1 and its substrates is likely to enhance our understanding of oral carcinogenesis and potential therapeutic value of PAKs in oral cancer.

Erythropoiesis-stimulating agents (ESAs) are often used in treatment of patients with chemotherapy-induced anemia. Many studies have demonstrated an improved hemoglobin (Hb) response when ESA is combined with intravenous iron supplementation and a higher effectiveness of intravenous iron over traditional oral iron formulations. A new formulation of oral sucrosomial iron featuring an increased bioavailability compared to traditional oral formulations has recently become available and could provide a valid alternative to those by intravenous (IV) route. Our study evaluated the performance of sucrosomial iron versus intravenous iron in increasing hemoglobin in anemic cancer patients receiving chemotherapy and darbepoetin alfa, as well as safety, need of transfusion, and quality of life (QoL). The present study considered a cohort of 64 patients with chemotherapy-related anemia (Hb >8 g/dL <10 g/dL) and no absolute or functional iron deficiency, scheduled to receive chemotherapy and darbepoetin. All patients received darbepoetin alfa 500 mcg once every 3 weeks and were randomly assigned to receive 8 weeks of IV ferric gluconate 125 mg weekly or oral sucrosomial iron 30 mg daily. The primary endpoint was to demonstrate the performance of oral sucrosomial iron in improving Hb response, compared to intravenous iron. The Hb response was defined as the Hb increase ≥2 g/dL from baseline or the attainment Hb ≥ 12 g/dL. There was no difference in the Hb response rate between the two treatment arms. Seventy one percent of patients treated with IV iron achieved an erythropoietic response, compared to 70% of patients treated with oral iron. By conventional criteria, this difference is considered to be not statistically significant. There were also no differences in the proportion of patients requiring red blood cell transfusions and changes in QoL. Sucrosomial oral iron was better tolerated. In cancer patients with chemotherapy-related anemia receiving darbepoetin alfa, sucrosomial oral iron provides similar increase in Hb levels and Hb response, with higher tolerability without the risks or side effects of IV iron.

Oral Supplementation with Non-Absorbable Antibiotics or Curcumin Attenuates Western Diet-Induced Atherosclerosis and Glucose Intolerance in LDLR−/− Mice – Role of Intestinal Permeability and Macrophage Activation

PubMed Central

Ghosh, Siddhartha S.; Bie, Jinghua; Wang, Jing; Ghosh, Shobha

2014-01-01

Association between circulating lipopolysaccharide (LPS) and metabolic diseases (such as Type 2 Diabetes and atherosclerosis) has shifted the focus from Western diet-induced changes in gut microbiota per se to release of gut bacteria-derived products into circulation as the possible mechanism for the chronic inflammatory state underlying the development of these diseases. Under physiological conditions, an intact intestinal barrier prevents this release of LPS underscoring the importance of examining and modulating the direct effects of Western diet on intestinal barrier function. In the present study we evaluated two strategies, namely selective gut decontamination and supplementation with oral curcumin, to modulate Western-diet (WD) induced changes in intestinal barrier function and subsequent development of glucose intolerance and atherosclerosis. LDLR−/− mice were fed WD for 16 weeks and either received non-absorbable antibiotics (Neomycin and polymyxin) in drinking water for selective gut decontamination or gavaged daily with curcumin. WD significantly increased intestinal permeability as assessed by in vivo translocation of FITC-dextran and plasma LPS levels. Selective gut decontamination and supplementation with curcumin significantly attenuated the WD-induced increase in plasma LPS levels (3.32 vs 1.90 or 1.51 EU/ml, respectively) and improved intestinal barrier function at multiple levels (restoring intestinal alkaline phosphatase activity and expression of tight junction proteins, ZO-1 and Claudin-1). Consequently, both these interventions significantly reduced WD-induced glucose intolerance and atherosclerosis in LDLR−/− mice. Activation of macrophages by low levels of LPS (50 ng/ml) and its exacerbation by fatty acids is likely the mechanism by which release of trace amounts of LPS into circulation due to disruption of intestinal barrier function induces the development of these diseases. These studies not only establish the important role of intestinal barrier function, but also identify oral supplementation with curcumin as a potential therapeutic strategy to improve intestinal barrier function and prevent the development of metabolic diseases.

Using a socio-ecological framework to guide the initiative, New Mexico Community Voices developed, with state and local stakeholders, responsive oral health policies to address oral health disparities. Several policy objectives were achieved: increasing awareness of the public health importance of oral health; improving access to dental services for uninsured or underserved populations; enhancing dental services specialty care; and increasing sustainable oral health infrastructure through pipeline development of oral health providers to relieve service shortages and diversify the oral health workforce. Improving access to oral health and augmenting numbers of dental providers in rural areas were also successful. The governor has appointed the New Mexico Oral Health Advisory Council to address state oral health issues. The New Mexico partnerships have demonstrated how effective policy change can generate important incremental shifts in oral health care delivery and provide best practice models that diminish the oral health crisis faced by underserved populations.

The aim of this study was to compare the efficacy of a single bilateral 12-minute vectored thermal pulsation (VTP) procedure versus daily oral doxycycline for 3 months for moderate-to-severe meibomian gland dysfunction (MGD). This prospective, randomized, parallel-group, single-masked study included 28 subjects who received either a single-dose VTP or 3 months of doxycycline treatment. At baseline and 3 months post treatment, all subjects were evaluated for the following: dry eye symptoms with a standard dry eye questionnaire (the Standard Patient Evaluation for Eye Dryness [SPEED]), meibomian gland (MG) function by counting the number of glands yielding liquid secretion with the MG evaluator (MGE), tear breakup time (TBUT) and corneal and conjunctival staining. In the VTP group, at 3 months, there was a significant improvement in MG function (4.00±1.47 to 7.73±5.53), SPEED score (11.00±3.30 to 5.42±2.15), TBUT (6.26±2.01 to 8.44±1.81), corneal staining (0.38±0.50 to 0.12±0.33) and conjunctival staining (1.69±1.93 to 0.62±0.85). In the doxycycline group, there was a significant improvement in MG function (4.63±1.41 to 10.63±5.91), SPEED score (13.42±4.17 to 9.42±5.47) and conjunctival staining (2.38±1.88 to 1.13±1.51), but the improvement in TBUT (6.90±2.56 to 7.59±2.03) and corneal staining (0.21±0.41 to 0.13±0.34) was not statistically significant ( p =0.262 and p =0.414, respectively). At 3 months, SPEED score was significantly better in the VTP group ( p <0.05); other parameters were comparable between the two groups. A single 12-minute bilateral VTP procedure was significantly more effective than the 3-month daily course of oral doxycycline at improving the dry eye symptoms secondary to MGD. A single 12-minute VTP treatment was at least as effective as a dose of doxycycline for 3 months, in improving MG function and all measured signs of MGD. Given the minimal risk profile of the single VTP procedure over long-term doxycycline use, a single VTP presents a favorable alternative to long-term antibiotic use.

School based oral health education through traditional lecturing has been found successful only in improving oral health knowledge, while has low effectiveness in oral hygiene and gingival health. The aim of this study was to evaluate the effectiveness of experiential learning (EL) oral health education to traditional lecturing (TL), on enhancing oral health knowledge, attitude and behavior as well as oral hygiene, gingival health and caries of 10-year-old children. Eighty-four children were recruited for the EL and 100 for the TL group from 3 locations in Greece. Data regarding oral health knowledge, attitude and behavior were collected via questionnaires. Data regarding dental plaque, gingivitis and caries were collected by clinical examination. The evaluation using questionnaires and clinical examination was assessed at baseline and 6 and 18 months afterwards. Two calibrated pediatric dentists examined the students using a periodontal probe and artificial light. Modified hygiene index (HI) was used for dental plaque recording, the simplified gingival index (GI-S) was used for gingivitis and DMFT, based on BASCD criteria, for dental caries. Based on a dedicated manual, the teacher applied in the classroom the oral health educational program using EL. EL group had statistically significant better hygiene than the TL at 6 months (p < 0.05). Within the same group, both groups had enhanced oral health knowledge at 6 and 18 months (p < 0.05) and improved oral health behavior (p > 0.05) and attitude (p > 0.05) at 6 months in comparison to baseline. EL program was found more successful than TL in oral hygiene improvement. Both oral health education programs improved the oral health knowledge, attitude and behavior of children.

Caregivers who work in community living arrangements or intermediate care facilities are responsible for the oral hygiene of individuals with intellectual and developmental disabilities. Oral hygiene training programs do not exist in many organizations, despite concerns about the oral care of this population. The purpose of this study was to determine the effectiveness of a caregiver educational program. This study used a quasi-experimental one-group pretest/posttest design with repeated measures to describe the outcomes of an educational program. Program participants demonstrated oral hygiene skills on each other while being scored by a trained observer, after which they completed an oral hygiene compliance survey. After three months, a follow-up included the same posttest, demonstration of oral hygiene skills, and repeat of the compliance survey. Paired-sample t-tests of oral hygiene knowledge showed a statistically significant improvement from pretest to posttest and from pretest to three-month posttest. Oral hygiene skills and compliance improved. Results demonstrate evidence that caregiver education improves knowledge, skill, and compliance in oral hygiene. Further studies are required to demonstrate the value of providing oral hygiene education and training for caregivers of individuals with intellectual and developmental disabilities.

The aim of this review was to discuss data from double-blind, randomized controlled trials (RCTs) that have investigated the effects of oral and long-acting injectable risperidone on cognitive and psychomotor functioning in patients with schizophrenia or schizoaffective disorder. PubMed/MEDLINE and the Institute of Scientific Information Web of Science database were searched for relevant English-language double-blind RCTs published between March 2000 and July 2008, using the terms schizophrenia, schizoaffective disorder, cognition, risperidone, psychomotor, processing speed, attention, vigilance, working memory, verbal learning, visual learning, reasoning, problem solving, social cognition, MATRICS, and long-acting. Relevant studies included patients with schizophrenia or schizoaffective disorder. Cognitive domains were delineated at the Consensus Conferences of the National Institute of Mental Health-Measurement And Treatment Research to Improve Cognition in Schizophrenia (NIMH-MATRICS). The tests employed to assess each domain and psychomotor functioning, and the within-group and between-group comparisons of risperidone with haloperidol and other atypical antipsychotics, are presented. The results of individual tests were included when they were individually presented and interpretable for either drug; outcomes that were presented as cluster scores or factor structures were excluded. A total of 12 articles were included in this review. Results suggested that the use of oral risperidone appeared to be associated with within-group improvements on the cognitive domains of processing speed, attention/vigilance, verbal and visual learning and memory, and reasoning and problem solving in patients with schizophrenia or schizoaffective disorder. Risperidone and haloperidol seemed to generate similar beneficial effects (on the domains of processing speed, attention/vigilance, [verbal and nonverbal] working memory, and visual learning and memory, as well as psychomotor functioning), although the results for verbal fluency, verbal learning and memory, and reasoning and problem solving were not unanimous, and no comparative data on social cognition were available. Similar cognitive effects were found with risperidone, olanzapine, and quetiapine on the domains of verbal working memory and reasoning and problem solving, as well as verbal fluency. More research is needed on the domains in which study results were contradictory. For olanzapine versus risperidone, these were verbal and visual learning and memory and psychomotor functioning. No comparative data for olanzapine and risperidone were available for the social cognition domain. For quetiapine versus risperidone, the domains in which no unanimity was found were processing speed, attention/vigilance, nonverbal working memory, and verbal learning and memory. The limited available reports on risperidone versus clozapine suggest that: risperidone was associated with improved, and clozapine with worsened, performance on the nonverbal working memory domain; risperidone improved and clozapine did not improve reasoning and problem-solving performance; clozapine improved, and risperidone did not improve, social cognition performance. Use of long-acting injectable risperidone seemed to be associated with improved performance in the domains of attention/vigilance, verbal learning and memory, and reasoning and problem solving, as well as psychomotor functioning. The results for the nonverbal working memory domain were indeterminate, and no clear improvement was seen in the social cognition domain. The domains of processing speed, verbal working memory, and visual learning and memory, as well as verbal fluency, were not assessed. The results of this review of within-group comparisons of oral risperidone suggest that the agent appeared to be associated with improved functioning in the cognitive domains of processing speed, attention/vigilance, verbal and visual learning and memory, and reasoning and problem solving in patients with schizophrenia or schizoaffective disorder. Long-acting injectable risperidone seemed to be associated with improved functioning in the domains of attention/vigilance, verbal learning and memory, and reasoning and problem solving, as well as psychomotor functioning, in patients with schizophrenia or schizoaffective disorder.

Chronic oral or intraarticular administration of docosahexaenoic acid reduces nociception and knee edema and improves functional outcomes in a mouse model of Complete Freund’s Adjuvant–induced knee arthritis

PubMed Central

2014-01-01

Introduction Clinical and preclinical studies have shown that supplementation with ω-3 polyunsaturated fatty acids (ω-3 PUFAs) reduce joint destruction and inflammation present in rheumatoid arthritis (RA). However, the effects of individual ω-3 PUFAs on chronic arthritic pain have not been evaluated to date. Thus, our aim in this study was to examine whether purified docosahexaenoic acid (DHA, an ω-3 PUFA) reduces spontaneous pain-related behavior and knee edema and improves functional outcomes in a mouse model of knee arthritis. Methods Unilateral arthritis was induced by multiple injections of Complete Freund’s Adjuvant (CFA) into the right knee joints of male ICR adult mice. Mice that received CFA injections were then chronically treated from day 15 until day 25 post–initial CFA injection with oral DHA (10, 30 and 100 mg/kg daily) or intraarticular DHA (25 and 50 μg/joint twice weekly). Spontaneous flinching of the injected extremity (considered as spontaneous pain-related behavior), vertical rearing and horizontal exploratory activity (considered as functional outcomes) and knee edema were assessed. To determine whether an endogenous opioid mechanism was involved in the therapeutic effect of DHA, naloxone (NLX, an opioid receptor antagonist, 3 mg/kg subcutaneously) was administered in arthritic mice chronically treated with DHA (30 mg/kg by mouth) at day 25 post–CFA injection. Results The intraarticular CFA injections resulted in increasing spontaneous flinching and knee edema of the ipsilateral extremity as well as worsening functional outcomes as time progressed. Chronic administration of DHA, given either orally or intraarticularly, significantly improved horizontal exploratory activity and reduced flinching behavior and knee edema in a dose-dependent manner. Administration of NLX did not reverse the antinociceptive effect of DHA. Conclusions To the best of our knowledge, this report is the first to demonstrate DHA’s antinociceptive and anti-inflammatory effects as individual ω-3 PUFAs following sustained systemic and intraarticular administration in a mouse model of CFA-induced knee arthritis. The results suggest that DHA treatment may offer a new therapeutic approach to alleviate inflammation as well as a beneficial effect on pain-related functional disabilities in RA patients.

Non-conventional therapeutics for oral infections

Allaker, Robert P; Ian Douglas, CW

As our knowledge of host-microbial interactions within the oral cavity increases, future treatments are likely to be more targeted. For example, efforts to target a single species or key virulence factors that they produce, while maintaining the natural balance of the resident oral microbiota that acts to modulate the host immune response would be an advantage. Targeted approaches may be directed at the black-pigmented anaerobes, Porphyromonas gingivalis and Prevotella intermedia, associated with periodontitis. Such pigments provide an opportunity for targeted phototherapy with high-intensity monochromatic light. Functional inhibition approaches, including the use of enzyme inhibitors, are also being explored to control periodontitis. More general disruption of dental plaque through the use of enzymes and detergents, alone and in combination, shows much promise. The use of probiotics and prebiotics to improve gastrointestinal health has now led to an interest in using these approaches to control oral disease. More recently the potential of antimicrobial peptides and nanotechnology, through the application of nanoparticles with biocidal, anti-adhesive and delivery capabilities, has been explored. The aim of this review is to consider the current status as regards non-conventional treatment approaches for oral infections with particular emphasis on the plaque-related diseases. PMID:25668296

We improved medial collateral ligament (MCL) healing throughout 90 days after surgical transection. We introduced intraperitoneal, per-oral (in drinking water) and topical (thin cream layer) peptide therapy always given alone, without a carrier. Previously, as an effective peptide therapy, stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, an anti-ulcer peptide effective in inflammatory bowel disease therapy (PL 14736)) particularly improved healing of transected tendon and muscle and wound healing effect including the expression of the early growth response 1 (egr-1) gene. After MCL transection BPC 157 was effective in rats when given once daily intraperitoneally (10 microg or 10 ng/kg) or locally as a thin layer (1.0 microg dissolved in distilled water/g commercial neutral cream) at the site of injury, first application 30 min after surgery and the final application 24 h before sacrifice. Likewise, BPC 157 was effective given per-orally (0.16 microg/ml in the drinking water (12 ml/day/rat)) until sacrifice. Commonly, BPC 157 microg-ng-rats exhibited consistent functional, biomechanical, macroscopic and histological healing improvements. Thus, we suggest BPC 157 improved healing of acute ligament injuries in further ligament therapy. (c) 2010 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Objectives: The aim of our study is to determine the changes in quality of life and patient′s perception of esthetic improvement after anterior maxillary osteotomy. Materials and Methods: Our prospective study consisted of 14 patients who had been diagnosed of skeletal orthodontic deformity and underwent anterior maxillary osteotomy, along with orthodontic correction. The quality of life was evaluated using questionnaires based on Oral Health Impact Profile-14 questionnaire (OHIP-14) and a 22-item orthognathic quality of life questionnaire. They were evaluated at baseline pre-surgical, 8 weeks postoperatively, and 24 weeks postoperatively. Results: Our results showed mild improvement in generic health related quality of life immediately following surgery, while condition-specific quality of life and patient′s perception of esthetic improvement were noted only at 24 weeks following anterior maxillary osteotomy. Conclusion: We conclude that anterior maxillary osteotomy had a positive impact on the quality of life. The improvement in patient's perception of esthetics is seen only 2 months after surgery, while improvements in oral health and function were seen within 2 months following surgery. The acceptance and satisfaction of patient toward surgery was more positive 2 months after surgery. PMID:23066273

This study investigated the clinical effectiveness of intervention with an open-mouth exercise device designed to facilitate maximal interincisal opening (MIO) and improve quality of life in patients with head and neck (H&N) cancer and oral submucous fibrosis (OSF). Sixty patients with H&N cancer, OSF, and trismus (MIO < 35 mm) participated in the functional rehabilitation program. An open-mouth exercise device intervention group and conventional group, each consisting of 20 patients, underwent a 12-week training and exercising program and follow-up. For the control group, an additional 20 patients were randomly selected to match the demographic characteristics of the aforementioned two groups. The patients' MIO improvements in the aforementioned three groups were 14.0, 10.5, and 1.3 mm, respectively. Results of this study confirm the significant improvement in average mouth-opening range. In addition, according to patient feedback, significant improvements in health-related quality of life and reductions in trismus symptoms occurred in the open-mouth exercise device group. This newly designed open-mouth exercise device can facilitate trismus patients with H&N cancer and OSF and improve mouth-opening range and quality of life.

The purpose of this study was to explore the predictive ability of factors associated with the Theory of Planned Behavior (TPB) on oral health behaviors. The participants of this descriptive, cross-sectional study were 179 first year medical students at the Carol Davila University of Medicine and Pharmacy that completed a questionnaire assessing TPB variables, self-identity and their current oral hygiene behaviors. Significant differences in self-identity regarding the toothbrushing behavior and reason for the dental visit were observed (p < 0.0001). When participants were classified in 2 groups according to their levels of self-identity, significant differences were found according to their age, toothbrushing frequency, attitudes, perceived behavioral control and intention for improving oral hygiene (p < 0.0001). Self-identity had a statistically significant positive correlation with affective attitudes, cognitive attitudes, subjective norms, perceived behavioral control and intention for improving oral hygiene. Hierarchical multiple regressions for toothbrushing frequency revealed that the TPB factors and self-identity explained 31% and 35% from the intention to improving behaviors, the coefficients for self-identity being significant. The structural equation model revealed the effect of self-identity on intention on improving oral health behaviors and the effect of past-behavior on self-identity. The findings revealed the value of the extended TPB model as a predictor of intention to improve oral health behaviors. Dental educators should focus on issues of students' self-identity as a person concerned by their oral health.

Hey, Penelope; Lokan, Julie; Johnson, Paul; Gow, Paul

2017-01-01

Primary sclerosing cholangitis (PSC) is a liver disease that leads to progressive destruction and stricturing of the biliary tree. Unfortunately, apart from orthotopic liver transplantation (OLT), there are no universally accepted therapies to treat this disease. Even following transplantation, recurrence of PSC is seen in approximately one quarter of patients and leads to high rates of graft failure. Oral vancomycin, through possible immunomodulatory and anti-inflammatory mechanisms, has been shown in small-scale studies to be successful in improving liver function tests in patients with pretransplant PSC. We report the first case of an adult patient diagnosed with recurrent PSC 4 years after OLT who was treated with oral vancomycin leading to complete normalisation of his liver biochemistry. This case adds to the growing literature of a potential therapeutic role for this antibiotic in PSC and highlights interesting questions regarding mechanisms of disease. PMID:28951512

Structural disruption of the gut microbiota and impaired goblet cell function are collateral etiologic factors in enteric diseases. Low, moderate, or high doses of a Bacillus licheniformis-B. subtilis mixture (BLS mix) were orally administered to piglets of genotype MUC4 that are supposed to be F4-expressing enterotoxigenic Escherichia coli strain (F4 + ETEC) F4ab/ac receptor negative (i.e., MUC4-resistant piglets) for 1 week before F4 + ETEC challenge. The luminal contents were collected from the mucosa of the colon on day 8 after F4 + ETEC challenge. The BLS mix attenuated E. coli-induced expansion of Bacteroides uniformis, Eubacterium eligens, Acetanaerobacterium, and Sporobacter populations. Clostridium and Turicibacter populations increased following F4 + ETEC challenge in pigs pretreated with low-dose BLS mix. Lactobacillus gasseri and Lactobacillus salivarius populations increased after administration of BLS mix during E. coli infection. The beneficial effects of BLS mix were due in part to the expansion of certain Clostridium, Lactobacillus, and Turicibacter populations, with a corresponding increase in the number of goblet cells in the ileum via upregulated Atoh1 expression, in turn increasing MUC2 production and thus preserving the mucus barrier and enhancing host defenses against enteropathogenic bacteria. However, excessive BLS mix consumption may increase the risk for enteritis, partly through disruption of colonic microbial ecology, characterized by expansion of Proteobacteria and impaired goblet cell function in the ileum. Our findings suggest that oral administration of BLS mix reprograms the gut microbiota and enhances goblet cell function to ameliorate enteritis. The present study is important for improving our understanding of the protective role of probiotics against Escherichia coli infection in piglets.

Infused and inhaled treprostinil are effective for treatment of pulmonary arterial hypertension (PAH), although their administration routes have limitations. This study assessed the efficacy and safety of bid oral sustained-release treprostinil in the treatment of PAH with a concomitant endothelin receptor antagonist (ERA) and/or phosphodiesterase type 5 inhibitor. A 16-week, multicenter, double-blind, placebo-controlled study was conducted in 350 patients with PAH randomized to placebo or oral treprostinil. All patients were stable on background ERA, PDE-5 inhibitor, or both. Primary end point was Hodges-Lehmann placebo-corrected median difference in change from baseline 6-min walk distance (6MWD) at week 16. Secondary end points included time to clinical worsening, change in World Health Organization functional class, Borg dyspnea score, and dyspnea fatigue index score. Thirty-nine patients (22%) receiving oral treprostinil and 24 patients (14%) receiving placebo discontinued the study. Placebo-corrected median difference in change from baseline 6MWD at week 16 was 11 m (P = .07). Improvements in dyspnea fatigue index score (P = .01) and combined 6MWD and Borg dyspnea score (P = .01) were observed with oral treprostinil vs placebo treatment. Patients who achieved a week-16 bid oral treprostinil dose of 1.25 to 3.25 mg and 3.5 to 16 mg experienced a greater change in 6MWD (18 m and 34 m, respectively) than patients who achieved a bid dose of < 1 mg or discontinued because of adverse events (4 m). The primary end point of improvement in 6MWD at week 16 did not achieve significance. This study enhanced understanding of oral treprostinil titration and dosing, which has set the stage for additional studies. ClinicalTrials.gov; No.: NCT00325442; URL: www.clinicaltrials.gov.

A systematic review of the effectiveness of health promotion aimed at improving oral health.

To examine the quality of oral health promotion research evidence and to assess the effectiveness of health promotion, aimed at improving oral health using a systematic and scientifically defensible methodology. Systematic review of oral health promotion research evidence using electronic searching, iterative hand-searching, critical appraisal and data synthesis. The settings of the primary research reviewed were clinical, community, schools or other institutions. The participants were children, the elderly, adults and people with handicaps and disabilities. Only studies which reported an evaluative component were included. Theoretical and purely descriptive papers were excluded. The review examined the evidence of effectiveness of oral health promotion on caries, oral hygiene, oral health related knowledge, attitudes and behaviours. Very few definitive conclusions about the effectiveness of oral health promotion can be drawn from the currently available evidence. Caries and periodontal disease can be controlled by regular toothbrushing with a fluoride toothpaste but a cost-effective method for reliably promoting such behaviour has not yet been established. Knowledge levels can almost always be improved by oral health promotion initiatives but whether these shifts in knowledge and attitudes can be causally related to changes in behaviour or clinical indices of disease has also not been established. Oral health promotion which brings about the use of fluoride is effective for reducing caries. Chairside oral health promotion has been shown to be effective more consistently than other methods of health promotion. Mass media programmes have not been shown to be effective. The quality of oral health promotion evaluation research needs to be improved.

Bite or brain: Implication of sensorimotor regulation and neuroplasticity in oral rehabilitation procedures.

Tooth loss, decreased mass and strength of the masticatory muscles leading to difficulty in chewing have been suggested as important determinants of eating and nutrition in the elderly. To compensate for the loss of teeth, in particular, a majority of the elderly rely on dental prosthesis for chewing. Chewing function is indeed an important aspect of oral health, and therefore, oral rehabilitation procedures should aim to restore or maintain adequate function. However, even if the possibilities to anatomically restore lost teeth and occlusion have never been better; conventional rehabilitation procedures may still fail to optimally restore oral functions. Perhaps this is due to the lack of focus on the importance of the brain in the rehabilitation procedures. Therefore, the aim of this narrative review was to discuss the importance of maintaining or restoring optimum chewing function in the superageing population and to summarise the emerging studies on oral motor task performance and measures of cortical neuroplasticity induced by systematic training paradigms in healthy participants. Further, brain imaging studies in patients undergoing or undergone oral rehabilitation procedures will be discussed. Overall, this information is believed to enhance the understanding and develop better rehabilitative strategies to exploit training-induced cortical neuroplasticity in individuals affected by impaired oral motor coordination and function. Training or relearning of oral motor tasks could be important to optimise masticatory performance in dental prosthesis users and may represent a much-needed paradigm shift in the approach to oral rehabilitation procedures. © 2018 John Wiley & Sons Ltd.

An orally active prostaglandin E1 analogue, OP-1206 alpha-CD improves walking dysfunction in the rat spinal stenosis model. Loxoprofen-Na, a non-steroidal anti-inflammatory drug, is used to relieve chronic pain in patients with lumbar spinal canal stenosis. To determine whether the OP-1206 alpha-CD in combination with loxoprofen-Na could induce a greater therapeutical effect on walking dysfunction and spinal cord blood flow (SCBF) than OP-1206 alpha-CD treatment alone after chronic spinal stenosis in the rat. Spinal stenosis was induced by placing two pieces of silicon rubber strips in the lumbar (L4 and L6) epidural space of rats. After surgery, walking function was measured using a treadmill apparatus and SCBF was measured using a laser-Doppler flow meter. Drugs were administered orally twice a day for 11 days from the day 3 post-surgery. OP-1206 alpha-CD elicited a significant improvement of walking dysfunction on days 7 and 14 post-surgery and significantly increased spinal cord blood flow on day 15, whereas walking dysfunction and SCBF of rats treated with loxoprofen-Na alone remained unchanged. Combined treatment of OP-1206 alpha-CD with loxoprofen-Na did not provide additive therapeutical effect. These results suggest that a significant improvement seen after OP-1206 alpha-CD treatment is primarily mediated by improvement of the local spinal cord blood flow. This effect is not ameliorated or potentiated by a combined treatment with loxoprofen-Na.

Despite vast improvements in the oral health status of the United States population over the past 50 years, disparities in oral health status continue, with certain segments of the population carrying a disproportionate disease burden. This article attempts to describe the problem, discuss various frameworks for action, illustrate some solutions developed by the private sector, and present a vision for collaborative action to improve the health of the nation. No one sector of the health care system can resolve the problem. The private sector, the public sector, and the not-for-profit community must collaborate to improve the oral health of the nation.

High intensity training (HIT) is effective at improving health; however, it is unknown whether HIT also improves physical function. This study aimed to determine whether HIT improves metabolic health and physical function in untrained middle aged individuals. Fourteen (three male and eleven female) untrained individuals were recruited (control group n = 6: age 42 ± 8 y, weight 64 ± 10 kg, BMI 24 ± 2 kg·m−2 or HIT group n = 8: age 43 ± 8 y, weight 80 ± 8 kg, BMI 29 ± 5 kg·m−2). Training was performed twice weekly, consisting of 10 × 6-second sprints with a one minute recovery between each sprint. Metabolic health (oral glucose tolerance test), aerobic capacity (incremental time to exhaustion on a cycle ergometer) and physical function (get up and go test, sit to stand test and loaded 50 m walk) were determined before and after training. Following eight weeks of HIT there was a significant improvement in aerobic capacity (8% increase in VO2 peak; p < 0.001), physical function (11%–27% respectively; p < 0.05) and a reduction in blood glucose area under the curve (6% reduction; p < 0.05). This study demonstrates for the first time the potential of HIT as a training intervention to improve skeletal muscle function and glucose clearance as we age. PMID:24833513

The presence of oral inflammation has recently been linked with the pathogenesis of cardiovascular diseases. While numerous studies have described links between periodontitis and endothelial dysfunction, little is known about the influence of denture-related stomatitis (DRS) on cardiovascular risk. Therefore, the aim of this study was to determine whether the treatment of DRS can lead to improvement of the clinical measures of vascular dysfunction. The DRS patients were treated with a local oral antifungal agent for 3 weeks. Blood pressure, flow-mediated dilatation (FMD) and nitroglycerine-mediated vascular dilatation (NMD) were measured during three study visits: before treatment, one day and two months after conclusion of antifungal therapy. Flow-mediated dilatation measurements showed significant improvement of endothelial function 2 months after treatment (FMD median 5%, 95 CI: 3-8.3 vs. 11%, 95% CI: 8.8-14.4; p < 0.01), while there was no difference in control, endothelium-independent vasorelaxations (NMD; median = 15.3%, 95% CI: 10.8-19.3 vs. 12.7%, 95% CI: 10.6-15; p = 0.3). Other cardiovascular parameters such as systolic (median = 125 mm Hg; 95% CI: 116-129 vs. 120 mm Hg, 95% CI: 116-126; p = 0.1) as well as diastolic blood pressure and heart rate (median = 65.5 bpm, 95% CI: 56.7-77.7 vs. 71 bpm, 95% CI: 66.7-75; p = 0.5) did not change during or after the treatment. Treatment of DRS is associated with improvement of endothelial function. Since endothelial dysfunction is known to precede the development of severe cardiovascular disorders such as atherosclerosis and hypertension, patients should be more carefully screened for DRS in general dental practice, and immediate DRS treatment should be advised.

The ability of older people to function independently is crucial as physical disability and functional limitation have profound impacts on health. Interventions that either delay the onset of frailty or attenuate its severity potentially have cascading benefits for older people, their families and society. This study aims to develop and evaluate the effectiveness of a multiComponent Exercise and theRApeutic lifeStyle (CERgAS) intervention program targeted at improving physical performance and maintaining independent living as compared to general health education among older people in an urban poor setting in Malaysia. This cluster randomised controlled trial will be a 6-week community-based intervention programme for older people aged 60 years and above from urban poor settings. A minimum of 164 eligible participants will be recruited from 8 clusters (low-cost public subsidised flats) and randomised to the intervention and control arm. This study will be underpinned by the Health Belief Model with an emphasis towards self-efficacy. The intervention will comprise multicomponent group exercise sessions, nutrition education, oral care education and on-going support and counselling. These will be complemented with a kit containing practical tips on exercise, nutrition and oral care after each session. Data will be collected over four time points; at baseline, immediately post-intervention, 3-months and 6-months follow-up. Findings from this trial will potentially provide valuable evidence to improve physical function and maintain independence among older people from low-resource settings. This will inform health policies and identify locally acceptable strategies to promote healthy aging, prevent and delay functional decline among older Malaysian adults. ISRCTN22749696.

Overdoses of acetaminophen (APAP), a famous and widely used drug, may have hepatotoxic effects. Nanoscience is a novel scientific discipline that provides specific tools for medical science problems including using nano trace elements in hepatic diseases. Our study aimed to assess the hepatoprotective role of selenium nanoparticles (Nano-Se) against APAP-induced hepatic injury. Twenty-four male rats were classified into three equal groups: a control group that received 0.9 % NaCl, an APAP-treated group (oral administration), and a group treated with Nano-Se (10-20 nm, intraperitoneal (i.p.) injection) and APAP (oral administration). APAP overdose induced significant elevations in liver function biomarkers, hepatic lipid peroxidation, hepatic catalase, and superoxide dismutase (SOD), decreased the reduced glutathione (GSH) content and glutathione reductase (GR) activity, and stimulated significant DNA damage in hepatocytes, compared to control rats. Nano-Se administration improved the hepatic antioxidant protection mechanism and decreased cellular sensitivity to DNA fragmentation. Nano-Se exhibits a protective effect against APAP-induced hepatotoxicity through improved liver function and oxidative stress mediated by catalase, SOD, and GSH and decreases hepatic DNA fragmentation, a hepatic biomarker of cell death. Nano-Se could be a novel hepatoprotective strategy to inhibit oxidative stress.

There is evidence that preoperative carbohydrate drinks and postoperative nutritional supplements improve the outcome of colorectal surgery. There is little information on their individual contribution. A prospective four-arm double-blind controlled trial was carried out in which patients were randomized to carbohydrate or placebo drinks preoperatively and a polymeric supplement or placebo drink postoperatively. The primary outcome was insulin resistance (using the short insulin tolerance test and HOMA-IR). Secondary outcomes included handgrip strength, pulmonary function, intestinal permeability and postoperative complications. A total of 120 patients were randomized to four demographically well matched groups. Patients who received preoperative and postoperative supplements had better glucose homeostasis (P = 0.004), peak expiratory flow rate (P = 0.035), handgrip strength (P = 0.002) and less insulin resistance (P = 0.001) compared with those who only received placebo drinks. Oral nutritional supplements given preoperatively and postoperatively improve postoperative handgrip strength, pulmonary function and insulin resistance. A weaker effect was seen in patients who received supplements either preoperatively or postoperatively. Oral nutritional supplements should be given both preoperatively and postoperatively.

Oral cancer has become one of the most aggressive types of cancer, killing 140,000 people worldwide every year. Current treatments for oral cancer include surgery and radiation therapies. These procedures can be very effective; however, they can also drastically decrease the quality of life for survivors. New chemotherapeutic treatments are needed to more effectively combat oral cancer. The transmembrane receptor podoplanin (PDPN) has emerged as a functionally relevant oral cancer biomarker and chemotherapeutic target. PDPN expression promotes tumor cell migration leading to oral cancer invasion and metastasis. Here, we describe the role of PDPN in oral squamous cell carcinoma progression, and how it may be exploited to prevent and treat oral cancer. Copyright © 2018 Elsevier Ltd. All rights reserved.

To study the blood clotting tests and endothelial function of polycystic ovary syndrome (PCOS) patients and non-hyperandrogenic women, and their changes during PCOS treatment, as a function of the presence of obesity and smoking. Case-control study followed by a randomized clinical trial. Blood clotting and endothelial function were analyzed in 40 PCOS patients and 20 non-hyperandrogenic women. Thirty-four PCOS women were randomized to an oral contraceptive containing 35 microg ethinyl-estradiol plus 2 mg cyproterone acetate (Diane(35)Diario) or metformin (850 mg twice daily), monitoring the changes on these parameters during 24 weeks of treatment. The influence of obesity and smoking was also analyzed. Blood clotting and endothelial function tests were similar among PCOS patients and controls with the exception of a higher platelet count in the former. Obesity increased circulating fibrinogen levels, prothrombin activity and platelet counts, and reduced prothrombin and activated partial thromboplastin times. Smoking increased fibrinogen levels, platelet counts, and prothrombin activity, and reduced prothrombin time, in relation to the larger waist circumference of smokers. Irrespective of the treatment received, PCOS patients showed a decrease in prothrombin time and an increase in prothrombin activity, with a parallel increase in homocysteine levels in metformin users. The activated partial thromboplastin time decreased markedly in the patients treated with Diane(35)Diario. Finally, flow-mediated dilation improved in non-smokers irrespective of the drug received, but worsened in smokers. Oral contraceptives and metformin may exert deleterious effects on blood clotting tests of PCOS women, yet the effects of metformin appear to be milder. Because smoking potentiates some of these effects and deteriorates endothelial function, smoking cessation should be promoted in PCOS patients.

To explore the enablers and barriers perceived by community nurses in the promotion of oral health in an adult community trust directorate. Oral health care promotion in community care settings is being neglected. England and Wales have witnessed marked improvements in periodontal disease; however, no improvements have been seen in older people. A qualitative methodology was employed, where eight nurses from Band 5 to 7 were interviewed using a semi-structured approach. The data was analysed thematically. Data analysis was organised into four themes: professional self-concept and the development of knowledge, skills and attitudes necessary in the promotion of oral health; the impact an organisation has on the promotion of oral health and an exploration of the enablers and barriers identified by the community nurses while delivering care; the relationships between the nurse and patient and the potential impact on oral health promotion; the concept of self-regard in relation to the promotion of oral health and its overall impact. A commitment to improving oral health and requests for additional educational input were apparent. Organisational enablers and barriers were identified, alongside the crucial role a positive self-regard for oral health care may play in the promotion of oral health. Nurses need relevant education, organisational support, adequate resources and support from a multidisciplinary team to deliver optimal oral health promotion.

Refractory asthma represents a significant unmet clinical need. Data from a national online registry audited clinical outcome in 349 adults with refractory asthma from four UK specialist centres in the British Thoracic Society Difficult Asthma Network. At follow-up, lung function improved, with a reduction in important healthcare outcomes, specifically hospital admission, unscheduled healthcare visits and rescue courses of oral steroids. The most frequent therapeutic intervention was maintenance oral corticosteroids and most steroid sparing agents (apart from omalizumab) demonstrated minimal steroid sparing benefit. A significant unmet clinical need remains in this group, specifically a requirement for therapies which reduce systemic steroid exposure.

The objective of this paper is to provide an improved technique, which can assist oncopathologists in correct screening of oral precancerous conditions specially oral submucous fibrosis (OSF) with significant accuracy on the basis of collagen fibres in the sub-epithelial connective tissue. The proposed scheme is composed of collagen fibres segmentation, its textural feature extraction and selection, screening perfomance enhancement under Gaussian transformation and finally classification. In this study, collagen fibres are segmented on R,G,B color channels using back-probagation neural network from 60 normal and 59 OSF histological images followed by histogram specification for reducing the stain intensity variation. Henceforth, textural features of collgen area are extracted using fractal approaches viz., differential box counting and brownian motion curve . Feature selection is done using Kullback-Leibler (KL) divergence criterion and the screening performance is evaluated based on various statistical tests to conform Gaussian nature. Here, the screening performance is enhanced under Gaussian transformation of the non-Gaussian features using hybrid distribution. Moreover, the routine screening is designed based on two statistical classifiers viz., Bayesian classification and support vector machines (SVM) to classify normal and OSF. It is observed that SVM with linear kernel function provides better classification accuracy (91.64%) as compared to Bayesian classifier. The addition of fractal features of collagen under Gaussian transformation improves Bayesian classifier's performance from 80.69% to 90.75%. Results are here studied and discussed.

To examine patients' and parents' perceptions and expectations from orthodontic treatment. 491 patients (274 female, 217 male) aged 14-22 years, and 399 parents (245 female, 154 male) completed a questionnaire about preferences, needs and expectations about orthodontic treatment, and scored the present problem. Continuous variables were compared by Mann-Whitney U and Kruskal-Wallis tests, whereas Chi-square test was used for categorical variables. Patients'(77.1%) and parents'(84.6%), decision about orthodontic treatments were influenced by suggestion of dentists. Patients who decided to attend to clinic by themselves were higher than parents (p=0.006). Dental aesthetics was the determinant factor for treatment demand for patients(61.0%) and parents(57.3%). Improvement in oral functions was more important for Class III patients than Class I patients (p=0.040). Adult patients/parents with higher education gave more importance to oral functions as well as dental aesthetics (p=0.031). There was no difference among Angle classifications regarding orthodontic problem scores. Parents found media sources valuable (p=0.018) but majority expected dentists for information about orthodontic treatments. Education degree of adult patients/parents effected this decision(p=0.002). Desire to have better dental aesthetics was the primary motivating factor for all participants. Clinicians should consider concerns of Class III patients about oral functions during treatment planning.

Because the oral hygiene is poorly prioritized in the immediate post-stroke period, we implemented an oral hygiene care program (OHCP) for stroke in-patients and evaluated its persistence after discharge. In all, 62 patients with stroke who were admitted to the rehabilitation ward were randomly assigned to two groups: 33 patients to the intervention group and 29 to the control group. The OHCP, including tooth brushing education and professional tooth cleaning, was administered to the intervention group twice a week six times during in-hospital rehabilitation. Oral health status was examined both at baseline and three months after discharge from the hospital. Oral hygiene status was examined at three- to four-day intervals five times during the hospitalization period. After OHCP, oral hygiene status including the plaque index, calculus index, and O'Leary plaque index improved significantly in the intervention group, compared to the control group (p < 0.05). In the intervention group, after administration of the OHCP for the fourth time, the O'Leary index improved significantly, and remained high when checked three months after discharge (p < 0.001). An OHCP conducted during in-hospital rehabilitation was effective in improving oral health and plaque control performance among patients with stroke, with effects still seen three months after discharge from the hospital. Implications for Rehabilitation Initial oral hygiene status and plaque control performance were poor in stroke patients who were in rehabilitation center. An oral hygiene care program during in-hospital rehabilitation was effective in improving oral hygiene status and plaque control performance among stroke patients at three months after discharge. Repeated tooth brushing education and professional tooth cleaning were necessary to improve plaque control performance of stroke patients.

Potential Applications of Phyto-Derived Ceramides in Improving Epidermal Barrier Function.

The outer most layer of the skin, the stratum corneum, consists of corneocytes which are coated by a cornified envelope and embedded in a lipid matrix of ordered lamellar structure. It is responsible for the skin barrier function. Ceramides (CERs) are the backbone of the intercellular lipid membranes. Skin diseases such as atopic dermatitis and psoriasis and aged skin are characterized by dysfunctional skin barrier and dryness which are associated with reduced levels of CERs. Previously, the effectiveness of supplementation of synthetic and animal-based CERs in replenishing the depleted natural skin CERs and restoring the skin barrier function have been investigated. Recently, however, the barrier function improving effect of plant-derived CERs has attracted much attention. Phyto-derived CERs (phytoCERs) are preferable due to their assumed higher safety as they are mostly isolated from dietary sources. The beneficial effects of phytoCER-based oral dietary supplements for skin hydration and skin barrier reinforcement have been indicated in several studies involving animal models as well as human subjects. Ingestible dietary supplements containing phytoCERs are also widely available on the market. Nonetheless, little effort has been made to investigate the potential cosmetic applications of topically administered phytoCERs. Therefore, summarizing the foregoing investigations and identifying the gap in the scientific data on plant-derived CERs intended for skin-health benefits are of paramount importance. In this review, an attempt is made to synthesize the information available in the literature regarding the effects of phytoCER-based oral dietary supplements on skin hydration and barrier function with the underlying mechanisms. © 2017 S.

Curcumin (CUR), the main polyphenol in turmeric, is poorly absorbed and rapidly metabolized following oral administration, which severely curtails its bioavailability. Poly-(lactic-co-glycolic acid)-based CUR nanoparticles (CUR-NP) have recently been suggested to improve CUR bioavailability, but this has not been fully verified. Specifically, no data are available about curcumin glucuronide (CURG), the major metabolite of CUR found in the plasma following oral administration of CUR-NP. Herein, we investigated the absorption and metabolism of CUR-NP and evaluated whether CUR-NP improves CUR bioavailability. Following oral administration of CUR-NP in rats, we analyzed the plasma and organ distribution of CUR and its metabolites using high-performance liquid chromatography-tandem mass spectrometry. To elucidate the mechanism of increased intestinal absorption of CUR-NP, we prepared mixed micelles comprised of phosphatidylcholine and bile salts and examined the micellar solubility of CUR-NP. Additionally, we investigated the cellular incorporation of the resultant micelles into differentiated Caco-2 human intestinal cells. Following in vivo administration of CUR-NP, CUR was effectively absorbed and present mainly as CURG in the plasma which contained significant amounts of the metabolite compared with other organs. Thus, CUR-NP increased intestinal absorption of CUR rather than decreasing metabolic degradation and conversion to other metabolites. In vitro, CUR encapsulated in CUR-NP was solubilized in mixed micelles; however, whether the micelles contained CUR or CUR-NP had little influence on cellular uptake efficiency. Therefore, we suggest that the high solubilization capacity of CUR-NP in mixed micelles, rather than cellular uptake efficiency, explains the high intestinal absorption of CUR-NP in vivo. These findings provide a better understanding of the bioavailability of CUR and CUR-NP following oral administration. To improve the bioavailability of CUR, future studies should focus on enhancing the resistance to metabolic degradation and conversion of CUR to other metabolites, which may lead to novel discoveries regarding food function and disease prevention.

Immunomodulatory dietary polysaccharides: a systematic review of the literature

PubMed Central

2010-01-01

Background A large body of literature suggests that certain polysaccharides affect immune system function. Much of this literature, however, consists of in vitro studies or studies in which polysaccharides were injected. Their immunologic effects following oral administration is less clear. The purpose of this systematic review was to consolidate and evaluate the available data regarding the specific immunologic effects of dietary polysaccharides. Methods Studies were identified by conducting PubMed and Google Scholar electronic searches and through reviews of polysaccharide article bibliographies. Only articles published in English were included in this review. Two researchers reviewed data on study design, control, sample size, results, and nature of outcome measures. Subsequent searches were conducted to gather information about polysaccharide safety, structure and composition, and disposition. Results We found 62 publications reporting statistically significant effects of orally ingested glucans, pectins, heteroglycans, glucomannans, fucoidans, galactomannans, arabinogalactans and mixed polysaccharide products in rodents. Fifteen controlled human studies reported that oral glucans, arabinogalactans, heteroglycans, and fucoidans exerted significant effects. Although some studies investigated anti-inflammatory effects, most studies investigated the ability of oral polysaccharides to stimulate the immune system. These studies, as well as safety and toxicity studies, suggest that these polysaccharide products appear to be largely well-tolerated. Conclusions Taken as a whole, the oral polysaccharide literature is highly heterogenous and is not sufficient to support broad product structure/function generalizations. Numerous dietary polysaccharides, particularly glucans, appear to elicit diverse immunomodulatory effects in numerous animal tissues, including the blood, GI tract and spleen. Glucan extracts from the Trametes versicolor mushroom improved survival and immune function in human RCTs of cancer patients; glucans, arabinogalactans and fucoidans elicited immunomodulatory effects in controlled studies of healthy adults and patients with canker sores and seasonal allergies. This review provides a foundation that can serve to guide future research on immune modulation by well-characterized polysaccharide compounds. PMID:21087484

To investigate change in oral health in relation to use of dental services, a random sample of 45- to 54-yr-old subjects from Adelaide, South Australia, was surveyed in 2004-2005 (n = 986, response rate = 44.4%). Service use and a global oral-health transition (GOHT) statement were collected over 2 yr. Worsening in oral health was reported from the GOHT statement by 25% of persons, while improvement was reported by 30%. Prevalence ratios (PRs, 95% CI), adjusted for sex, education, health card status, and toothbrushing, showed that worsening oral health was inversely associated with dental visiting (PR = 0.5, 0.4-0.7) and with scaling and cleaning services (PR = 0.6, 0.4-0.9), whereas extractions (PR = 2.3, 1.6-3.4) and dentures (PR = 2.2, 1.3-3.7) were associated with a higher prevalence of worsening. Scaling and cleaning services were associated with improvement in oral health (PR = 1.5, 1.01-2.3), while endodontic services were inversely associated with improvement (PR = 0.3, 0.1-0.9). Worsening in oral health was associated with extractions and dentures and was inversely associated with visiting and preventive care. Improvement in oral health was associated with preventive care and was inversely associated with endodontic treatment. © 2012 Eur J Oral Sci.

This study investigated the relationship between family functioning and childhood dental caries. Further objectives were (i) to explore whether oral hygiene behaviours could account for a possible association between family functioning dimensions and childhood dental caries and (ii) to explore whether family functioning could mediate the relationship between sociodemographic factors and childhood dental caries. A random sample of 630 5- to 6-year-old children was recruited from six large paediatric dental centres in the Netherlands. Children's dmft scores were extracted from personal dental records. A parental questionnaire and the Gezinsvragenlijst (translation: Family Questionnaire) were used to collect data on sociodemographic characteristics, oral hygiene behaviours and family functioning. Family functioning was assessed on five dimensions: responsiveness, communication, organization, partner-relation and social network. Associations with dmft were analysed using multilevel modelling. Bivariate analysis showed that children from normal functioning families on the dimensions responsiveness, communication, organization and social network had significantly lower dmft scores compared with children from dysfunctional families. Poorer family functioning on all dimensions was associated with an increased likelihood of engaging in less favourable oral hygiene behaviours. Children with lower educated mothers, immigrant children and children of higher birth order were more likely to come from poorer functioning families. In multivariate analysis, organization remained a significant predictor of dmft after adjusting for the other family functioning dimensions and the mother's education level, but it lost statistical significance after adjustment for oral hygiene behaviours. A relationship between family functioning and childhood dental caries was found, which may have operated via oral hygiene behaviours. Family functioning modestly explained socioeconomic inequalities in child oral health. Organization appeared to be the most important dimension of family functioning that influenced children's caries experience. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Intrathecal Baclofen Pump for Spasticity

PubMed Central

2005-01-01

Executive Summary Objective To conduct an evidence-based analysis of the effectiveness and cost-effectiveness of intrathecal baclofen for spasticity. The Technology Spasticity is a motor disorder characterized by tight or stiff muscles that may interfere with voluntary muscle movements and is a problem for many patients with multiple sclerosis (MS), spinal cord injury (SCI), cerebral palsy (CP), and acquired brain injury (ABI).(1). Increased tone and spasm reduces mobility and independence, and interferes with activities of daily living, continence and sleep patterns. Spasticity may also be associated with significant pain or discomfort (e.g., due to poor fit in braces, footwear, or wheelchairs), skin breakdown, contractures, sleep disorders and difficulty in transfer. Goals of treatment are to decrease spasticity in order to improve range of motion, facilitate movement, reduce energy expenditure and reduce risk of contractures. Existing treatments include physical therapy, oral medications, injections of phenol or botulinum toxin, or surgical intervention. Baclofen is the oral drug most frequently prescribed for spasticity in cases of SCI and MS.(1) Baclofen is a muscle relaxant and antispasticity drug. In the brain, baclofen delivered orally has some supraspinal activity that may contribute to clinical side effects. The main adverse effects of oral baclofen include sedation, excessive weakness, dizziness, mental confusion, and somnolence.(2) The incidence of adverse effects is reported to range from 10% to 75%.(2) Ochs et al. estimated that approximately 25-30% of SCI and MS patients fail to respond to oral baclofen.(3;4) Adverse effects appear to be dose-related and may be minimized by initiating treatment at a low dose and gradually titrating upwards.(2) Adverse effects usually appear at doses >60 mg/day.(2) The rate of treatment discontinuation due to intolerable adverse effects has generally been reported to range from 4% to 27%.(2) When baclofen is administered orally, only a small portion of the original dose crosses the blood brain barrier and enters the central nervous system (CNS) fluid, which is the site of drug action. In order to bypass the oral route, baclofen may be administered intrathecally by infusion directly to the CNS. Candidates for intrathecal baclofen infusion are patients with spasticity who have intractable spasticity uncontrolled by drug therapy, or who experience intolerable side effects from oral baclofen. Advantages of intrathecal baclofen infusion are: Direct drug administration to the cerebrospinal fluid (CSF) The central side effects of oral baclofen, such as drowsiness or confusion, appear to be minimized with intrathecal administration. The intrathecal delivery of baclofen concentrates the drug in the CSF at higher levels than those attainable via the oral route. Intrathecal administration can use concentrations of baclofen of less than one hundredth of those used orally.(5) Adjustable/programmable continuous infusion makes it possible to finely titrate patients’ doses and to vary the doses over the hours of the day. For example, the dose can be relatively low to give the patients the extensor tone needed for ambulation during the day and increased at night, thereby improving quality of sleep. Reversible (in contrast to surgery). A patient who is a candidate for intrathecal baclofen infusion must have no contraindications to the insertion of an intrathecal catheter (e.g., anticoagulant therapy, coagulopathy, local or systemic infection, anatomical abnormality of the spine). Review Strategy The Medical Advisory Secretariat reviewed the literature to assess the effectiveness, safety, and cost-effectiveness of intrathecal baclofen to treat patients who have intractable spasticity uncontrolled by drug therapy, or who experience intolerable side effects to oral baclofen. The Medical Advisory Secretariat used its standard search strategy to retrieve international health technology assessments and English-language journal articles from selected databases. Summary of Findings Level 2 evidence supports the effectiveness of intrathecal baclofen infusion for the short-term reduction of severe spasticity in patients who are unresponsive or cannot tolerate oral baclofen Level 3 evidence supports the effectiveness of intrathecal baclofen for the long-term reduction of severe spasticity in patients who are unresponsive or cannot tolerate oral baclofen Level 4 qualitative evidence demonstrates functional improvement for patients who are unresponsive or cannot tolerate oral baclofen Intrathecal baclofen is cost-effective with costs which may or may not be avoided in the Ontario health system True functional use remains to be determined PMID:23074476

Purpose. Inflammation contributes significantly to the pathogenesis of diabetic macular edema (DME). In particular, retinal microglia demonstrate increased activation and aggregation in areas of DME. Study authors investigated the safety and potential efficacy of oral minocycline, a drug capable of inhibiting microglial activation, in the treatment of DME. Methods. A single-center, prospective, open-label phase I/II clinical trial enrolled five participants with fovea-involving DME who received oral minocycline 100 mg twice daily for 6 months. Main outcome measurements included best-corrected visual acuity (BCVA), central retinal subfield thickness (CST), and central macular volume using spectral domain optical coherence tomography (SD-OCT) and late leakage on fluorescein angiography (FA). Results. Findings indicated that the study drug was well tolerated and not associated with significant safety issues. In study eyes, mean BCVA improved continuously from baseline at 1, 2, 4, and 6 months by +1.0, +4.0, +4.0, and +5.8 letters, respectively, while mean retinal thickness (CST) on OCT decreased by −2.9%, −5.7%, −13.9, and −8.1% for the same time points. At month 6, mean area of late leakage on FA decreased by −34.4% in study eyes. Mean changes in contralateral fellow eyes also demonstrated similar trends. Improvements in outcome measures were not correlated with concurrent changes in systemic factors. Conclusions. In this pilot proof-of-concept study of DME, minocycline as primary treatment was associated with improved visual function, central macular edema, and vascular leakage, comparing favorably with historical controls from previous studies. Microglial inhibition with oral minocycline may be a promising therapeutic strategy targeting the inflammatory etiology of DME. (ClinicalTrials.gov number, NCT01120899.) PMID:22589436

Oral squamous cell carcinoma is a common and lethal malignancy affecting the head and neck region. CCAT2 (colon cancer-associated transcript 2) gene is affiliated with long non-coding RNAs, which are often found to have important regulatory roles in cancers. This study aims to assess the expression and clinical significance of CCAT2 gene, identify its malignant biological behaviors, and explore the possible mechanisms in oral squamous cell carcinoma. CCAT2 expression was detected by quantitative real-time polymerase chain reaction, and its relationship with clinical factors was assayed using the Kaplan-Meier survival curve. The biological behaviors of CCAT2 and its potential mechanisms in oral squamous cell carcinoma were explored by the combined use of CCAT2 knockdown technology and the Wnt/β-catenin pathway agonist lithium chloride (LiCl). Our results showed that CCAT2 functioning as a potential oncogene was upregulated in oral squamous cell carcinoma. CCAT2 with high expression level was correlated with poor differentiation, higher T stage, and clinical stage, which made CCAT2 to be a prognostic biomarker in oral squamous cell carcinoma. LiCl-activated Wnt/β-catenin signaling pathway could partly restore the CCAT2-mediated malignant biological behaviors of oral squamous cell carcinoma cells by suppressing β-catenin, CCND1, and MYC and activating glycogen synthase kinase 3 beta expression. These findings might assist in the discovery of novel potential diagnostic and therapeutic target for oral squamous cell carcinoma, thereby improve the effects of clinical treatment in patients.

Melanin: the biophysiology of oral melanocytes and physiological oral pigmentation

PubMed Central

2014-01-01

The presence of melanocytes in the oral epithelium is a well-established fact, but their physiological functions are not well defined. Melanin provides protection from environmental stressors such as ultraviolet radiation and reactive oxygen species; and melanocytes function as stress-sensors having the capacity both to react to and to produce a variety of microenvironmental cytokines and growth factors, modulating immune, inflammatory and antibacterial responses. Melanocytes also act as neuroendocrine cells producing local neurotransmitters including acetylcholine, catecholamines and opioids, and hormones of the melanocortin system such as proopiomelanocortin, adrenocorticotropic hormone and α-melanocyte stimulating hormone, that participate in intracellular and in intercellular signalling pathways, thus contributing to tissue homeostasis. There is a wide range of normal variation in melanin pigmentation of the oral mucosa. In general, darker skinned persons more frequently have oral melanin pigmentation than light-skinned persons. Variations in oral physiological pigmentation are genetically determined unless associated with some underlying disease. In this article, we discuss some aspects of the biophysiology of oral melanocytes, of the functions of melanin, and of physiological oral pigmentation. PMID:24661309

The aim of this study was to evaluate whether an interdisciplinary, multifaceted oral health education program delivered to pediatric nurse practitioner students at the University of California, San Francisco, would improve their knowledge, confidence, attitudes, and behaviors regarding the provision of oral health assessments, consultations, referrals, and services to young children during well-child visits. Thirty pediatric nurse practitioner students were included in the study. Participants completed a written survey before and after receiving an interdisciplinary educational intervention that included didactic education, simulation exercises, and clinical observation by a pediatric dental resident. Between pre-intervention and post-intervention, a significant improvement was seen in the pediatric nurse practitioners’ knowledge of oral health topics (p<0.001), confidence when providing oral health counseling (p<0.001), and attitudes about including oral health counseling in their examinations (p=0.006). In the post-intervention survey, 83 percent of the subjects reported having incorporated oral examinations into their well-child visits. Our study suggests that providing an interdisciplinary oral health educational program for pediatric nurse practitioner students can improve their knowledge, confidence, attitudes, and behaviors regarding the incorporation of oral health care services during routine well-child visits.

To determine the use of oral anticoagulants in polypathological patients with atrial fibrillation and its influence on mortality and loss of functionality. Patients with polypathological patient criteria and atrial fibrillation were included in an observational, prospective and multicenter study. Data on demographic, clinical, functional and sociofamilial characteristics, CHADS2 score, levels of hemoglobin, albumin and creatinine, use of oral anticoagulants and survival and functional status at one year were collected. Five hundred and thirty-two (32.6%) of 1,632 polypathological patients had atrial fibrillation. The stroke risk was high in 505 (94.9%), moderate in 24 (4.5%) and low in 3 (0.6%) patients. Oral anticoagulants were used in 61% of patients with CHADS2 score≥2 and in 37.5% with CHADS2 score=1. Oral anticoagulants were less used in older patients, with more functional and cognitive impairment. Heart failure was associated with more use of oral anticoagulants. There was no difference by the presence of hypertension, diabetes, anemia, renal insufficiency or stroke. In multivariate analysis the use of oral anticoagulants was independently associated with lower age, lower cognitive impairment, absence of hepatic disease and with higher stroke risk. The prescription of oral anticoagulants was independently associated with more survival at one year with no influence on functional status. Oral anticoagulants are underused in polypathological patients with atrial fibrillation despite being associated with more survival. Copyright © 2012 Elsevier España, S.L. All rights reserved.

The aim of this follow-up study was to measure the self-reported frequency and severity of bullying in orthodontic patients previously identified as being bullied, who have commenced interceptive orthodontic treatment, and to investigate the effect on an individual's self-esteem and oral-health-related quality of life (OHRQoL). Forty-three adolescents previously identified as being bullied due to the presence of a malocclusion were invited to take part in a follow-up study following commencement of orthodontic treatment at three UK Hospitals. Validated questionnaires were used to assess the self-reported frequency and severity of bullying, self-esteem and OHRQoL. The participation rate at follow-up was 63 per cent. Following commencement of orthodontic treatment, 21 (78 per cent) participants reported they were currently no longer being bullied due to the presence of their malocclusion. In comparison to their pre-treatment scores, participants reported fewer functional limitations (P = 0.013), decreased emotional (P < 0.001) and social impact (P < 0.001), and improved overall oral health (P = 0.03) and OHRQoL (P = 0.002). In addition, an improvement in functional limitations (P = 0.021), emotional (P = 0.008), social impact (P = 0.008) and OHRQoL (P = 0.02) was reported by participants who were no longer being bullied in comparison to those who continued to report bullying. There appears to be no effect on an individual's self-esteem. Orthodontic treatment may have a positive effect on adolescents experiencing bullying related to their malocclusion and their OHRQoL.

The aim of this study was to develop the Teen Oral Health-Related Quality of Life instrument (TOQOL) and demonstrate its validity and reliability in a diverse sample of 13-18-year-old adolescents. A total of 363 adolescents aged 13-18 years participated in this cross sectional study. Oral screening examinations were conducted to collect oral health status data. Adolescents completed the TOQOL and a generic measure of health-related quality of life, the PedsQL. The psychometric properties of the TOQOL were evaluated in terms of face, content, convergent, concurrent and discriminant validity in addition to internal reliability. The 16-item TOQOL covers five domains: Physical functioning, Role functioning, Social functioning, Oral problems, and Emotional functioning. The total scale and subscales showed satisfactory reliability with Cronbach alpha ranging from 0.75 to 0.92. TOQOL scores showed significant associations with perceived oral health status and the PedsQL (convergent validity) and discriminated well between adolescents with caries and adolescents who were caries free (discriminate validity). The TOQOL is a valid and reliable oral health-related quality of life measurement that can be recommended for self-report in adolescents aged 13-18 years. © 2016 American Association of Public Health Dentistry.

Very little is known about the potential relationship between welfare state regimes and oral health. This study assessed the oral health of adults in a range of European countries clustered by welfare regimes according to Ferrera's typology and the complementary Eastern type. We analysed data from Eurobarometer wave 72.3, a cross-sectional survey of 31 European countries carried out in 2009. We evaluated three self-reported oral health outcomes: edentulousness, no functional dentition (<20 natural teeth), and oral impacts on daily living. Age-standardized prevalence rates were estimated for each country and for each welfare state regime. The Scandinavian regime showed lower prevalence rates for all outcomes. For edentulousness and no functional dentition, there were higher prevalence rates in the Eastern regime but no significant differences between Anglo-Saxon, Bismarckian, and Southern regimes. The Southern regime presented a higher prevalence of oral impacts on daily living. Results by country indicated that Sweden had the lowest prevalences for edentulousness and no functional dentition, and Denmark had the lowest prevalence for oral impacts. The results suggest that Scandinavian welfare states, with more redistributive and universal welfare policies, had better population oral health. Future research should provide further insights about the potential mechanisms through which welfare-state regimes would influence oral health. © 2013 Eur J Oral Sci.

Despite the high rate of untreated tooth decay, many young children in California under six years of age have never been to a dentist. Numerous and complex barriers to access to oral health care for young children exist, and a multifaceted approach is required to improve receipt of preventive and treatment services that could improve the oral health of this population. This policy brief describes the UCLA-First 5 LA 21st Century Dental Homes Project, which was designed to improve oral health care for young children in 12 Federally Qualified Health Center (FQHC) clinic sites with co-located dental and primary care services and its accessibility in their service areas throughout Los Angeles County. The project funded infrastructure and staffing, provided technical assistance to improve operations, trained clinical personnel to provide oral health care to young children, implemented a quality improvement learning collaborative, trained parents and child care providers in oral hygiene and healthy habits, and disseminated information to promote effective policies. Early data on the project indicated twofold increases in delivery of both diagnostics and treatment visits for young children, and a threefold increase in preventive services for young children during the program.

To investigate clinical oral disease and its association with cognitive function and dependency among older New Zealanders in residential aged care. National survey of oral health in aged residential care throughout New Zealand. We classified residents into 1 of 3 levels of care: "low dependency care (or assisted living)"; "high dependency care"; or "specialist dementia care/psychogeriatric care." The Abbreviated Mental Test characterised cognitive function as "unimpaired" (scores of 7-10), "moderately impaired" (4-6) or "severely impaired" (0-3). Intra-oral examinations were conducted, along with a computer-assisted personal interview. Most of the 987 clinically examined participants were either at low or high dependency care level, with another 1 in 6 in psychogeriatric care. Almost half overall had severely impaired cognitive function. Just under half of the sample had 1 or more natural teeth remaining. Negative binomial regression modelling showed that the number of carious teeth was lower among women and higher among those who were older, those with more teeth and in those with severely impaired cognitive function. Oral debris scores (representing plaque biofilm and other soft deposits on teeth) were higher in men, those with more teeth, and in those with severely impaired cognitive function. Impaired cognitive function is a risk indicator for both dental caries and oral debris in aged residential care. © 2018 John Wiley & Sons A/S and The Gerodontology Association.

Providing ketone bodies to the brain can bypass metabolic blocks to glucose utilization and improve function in energy-starved neurons. For this, plasma ketones must be elevated well above the ≤ 0.2 mM default concentrations normally prevalent. Limitations of dietary methods currently used to produce therapeutic hyperketonemia have stimulated the search for better approaches. Described herein is a new way to produce therapeutic hyperketonemia, entailing prolonged oral administration of a potent ketogenic agent--ketone monoester (KME)--to a patient with Alzheimer's disease dementia and a pretreatment Mini-Mental State Examination score of 12. The patient improved markedly in mood, affect, self-care, and cognitive and daily activity performance. The KME was well tolerated throughout the 20-month treatment period. Cognitive performance tracked plasma β-hydroxybutyrate concentrations, with noticeable improvements in conversation and interaction at the higher levels, compared with predose levels. KME-induced hyperketonemia is robust, convenient, and safe, and the ester can be taken as an oral supplement without changing the habitual diet. Published by Elsevier Inc.

Type 2 diabetes (T2D) is associated with generalized vascular dysfunction characterized by increases in large artery stiffness, endothelial dysfunction, and vascular smooth muscle dysfunction. Sodium glucose cotransporter 2 inhibitors (SGLT2i) represent the most recently approved class of oral medications for the treatment of T2D, and have been shown to reduce cardiovascular and overall mortality. Although it is currently unclear how SGLT2i decrease cardiovascular risk, an improvement in vascular function is one potential mechanism. The aim of the current study was to examine if dapagliflozin, a widely prescribed STLT2i, improves generalized vascular dysfunction in type 2 diabetic mice. In light of several studies demonstrating a bi-directional relation between orally ingested medications and the gut microbiota, a secondary aim was to determine the effects of dapagliflozin on the gut microbiota. Male diabetic mice (Db, n = 24) and control littermates (Con; n = 23) were randomized to receive either a standard diet or a standard diet containing dapagliflozin (60 mg dapagliflozin/kg diet; 0.006%) for 8 weeks. Arterial stiffness was assessed by aortic pulse wave velocity; endothelial function and vascular smooth muscle dysfunction were assessed by dilatory responses to acetylcholine and sodium nitroprusside, respectively. Compared to untreated diabetic mice, diabetic mice treated with dapagliflozin displayed significantly lower arterial stiffness (Db = 469 cm/s vs. Db + dapa = 435 cm/s, p < 0.05), and improvements in endothelial dysfunction (area under the curve [AUC] Db = 57.2 vs. Db + dapa = 117.0, p < 0.05) and vascular smooth muscle dysfunction (AUC, Db = 201.7 vs. Db + dapa = 285.5, p < 0.05). These vascular improvements were accompanied by reductions in hyperglycemia and circulating markers of inflammation. The microbiota of Db and Con mice were distinctly different, and dapagliflozin treatment was associated with minor alterations in gut microbiota composition, particularly in Db mice, although these effects did not conclusively mediate the improvements in vascular function. Dapagliflozin treatment improves arterial stiffness, endothelial dysfunction and vascular smooth muscle dysfunction, and subtly alters microbiota composition in type 2 diabetic mice. Collectively, the improvements in generalized vascular function may represent an important mechanism underlying the cardiovascular benefits of SGLT2i treatment.

This prospective study aimed to investigate the evolution of chewing efficiency, maximum voluntary bite force (MBF) and oral health-related quality of life (OHRQoL) in edentulous patients treated with narrow diameter implants (NDIs) over the course of 1 year. Four NDIs (MDI ® , 3M ESPE, diameter 1.8 mm) were placed interforaminally in 20 edentulous patients. They were immediately loaded by converting the existing prosthesis into an implant overdenture. Participants were examined six times pre- and postoperatively [baseline (BL) to week 52 (w52)]. Chewing efficiency was evaluated with a colour-mixing ability test by evaluation of the standard deviation of hue (VOH, ViewGum©). MBF was measured using a digital force gauge. OHRQoL was determined with the Oral Health Impact Profile (OHIPG49). Nonparametric Brunner-Langer models were applied for statistical testing. The study failed to demonstrate an effect on chewing efficiency. MBF increased continuously during the observation period (medians: MBF[N]@BL = 46.6 [iqr 50.1]; MBF[N]@w52 = 103.9 [iqr 76.0]; P = 0.002). OHRQoL increased steeply after implant loading and continued improving (medians: BL ∑OHIPG49 = 31 [iqr 40.0]; w4 ∑OHIPG49 = 11.5 [iqr 19.5]; w52 ∑OHIPG49 = 6 [iqr 13.0], P < 0.001). The stabilisation of a lower complete prosthesis with four NDIs is a feasible minimally invasive and economical approach to improve oral function and OHRQoL, especially in elderly patients with limited bone support. Functional benefits might be more evident if patients receive chewing instructions. Larger studies need to confirm a positive effect on chewing efficiency and develop long-term maintenance solutions if patients become frail because no easy downgrading approaches of one-piece titanium implants exist. © 2016 John Wiley & Sons A/S.

Thymomodulin (Ellem Industria Farmaceutica s.p.a., Milan, Italy) is a calf thymus acid lysate derivative, composed of several peptides with a molecular weight range of 1-10 kD. Thymomodulin did not exhibit any mutagenic effect. Furthermore, thymomodulin used in animal studies showed no toxicity even when used at high concentrations. Of major significance are the observations in murine and human systems that thymomodulin remains active when administered orally. In vitro and in vivo administered thymomodulin was able to induce the maturation of T-lymphocytes. Additionally, studies in vitro showed that this thymic derivative can enhance the functions of mature T-lymphocytes with cascading effects on B-cell and macrophage functions. Extensive human clinical trials with thymomodulin showed that this agent can improve the clinical symptoms observed with various disease processes, including infections, allergies and malignancies, and can improve immunological functions during ageing.

Some stroke patients show oral phase dysphagia, characterized by a markedly prolonged oral transit time that hinders oral feeding. The aim of this study was to clarify the clinical characteristics and lesions responsible for delayed swallowing. We reviewed 90 patients with stroke. The oral processing time plus the postfaucial aggregation time required to swallow semisolid food was assessed. The patients were divided into two groups according to oral transit time, and we analyzed the differences in characteristics such as demographic factors, lesion factors, and cognitive function. Logistic regression analyses were performed to examine the predictors of delayed oral transit time. Lesion location and volume were measured on brain magnetic resonance images. We generated statistic maps of lesions related to delayed oral phase in swallowing using voxel-based lesion symptom mapping (VLSM). The group of patients who showed delayed oral transit time had significantly low cognitive function. Also, in a regression model, delayed oral phase was predicted with low K-MMSE (Korean version of the Mini Mental Status Exam). Using VLSM, we found the lesion location to be associated with delayed oral phase after adjusting for K-MMSE score. Although these results did not reach statistical significance, they showed the lesion pattern with predominant distribution in the left frontal lobe. Delayed oral phase in post-stroke patients was not negligible clinically. Patients' cognitive impairments affect the oral transit time. When adjusting it, we found a trend that the lesion responsible for delayed oral phase was located in the left frontal lobe, though the association did not reach significance. The delay might be related to praxis function.

It has been reported that children's oral health conditions are correlated with their attendance to dental health services. Evaluating the influencing factors of utilization of dental services for children may give ways to improve the services per se, and furtherly the children's oral health. The present review retrieved and summarized domestic and foreign studies on the utilization of oral health services for children based on the Andersen behavior model. It was concluded that the utilization of dental services for children was affected by demographic characteristics, social structure, health belief, family factors, community factors and perceived/evaluated needs. To improve the utilization of dental services for children, effort should be made by means of changing caregivers' health belief, developing oral health insurance system, setting up regular oral health resources and increasing the financial support for oral health services by government.

How people on social assistance perceive, experience, and improve oral health.

Oral diseases are highly prevalent among people on social assistance. Despite benefiting from public dental coverage in North America, these people rarely consult the dentist. One possible reason is rooted in their perception of oral health and the means to improve it. To respond to this question, largely unexplored, we conducted qualitative research through 8 focus groups and 15 individual interviews in Montreal (Canada). Thematic analysis revealed that people on social assistance: (a) define oral health in a social manner, placing tremendous value on dental appearance; (b) complain about the decline of their dental appearance and its devastating impact on self-esteem, social interaction, and employability; and (c) feel powerless to improve their oral health and therefore contemplate extractions and complete dentures. Our research demonstrates that perception of oral health strongly influences treatment preference and explains low and selective use of dental services in this disadvantaged population.

Orthognathic surgery to correct serious skeletal discrepancies of the jaw improves both function and appearance, but patients should spend a lot of time thinking about, discussing, and planning operations that have such a considerable impact. The drive to improve appearance by such radical means is based on social and personal reasons, and this must be understood before treatment is considered.

The present study was conducted in order to determine what item of biological and psychosocial function is related to oral health status in the bedridden elderly. The subjects were 94 elderly individuals (30 males, 64 females) who had been admitted to a nursing home in Chiba city, Japan. We assessed the number of remaining teeth and the number of functional teeth as oral health status variables. Biological and psychosocial function levels were determined using the functional independence measure method developed by the State University of New York at Buffalo. More than 70% of subjects had less than ten remaining teeth. Almost all subjects needed prosthesis treatment. More than 50% of subjects had 27 or less functional teeth. Mann-Whitney U-test and logistic regression models showed that 'expression' was concerned with the number of remaining teeth and 'bladder management', 'locomotion', 'transfers' were related to the number of functional teeth. These data suggest close relation between oral health status and biological and psychosocial function levels in the bedridden elderly.

Globally, dental caries is categorized in the list of public health problems in preschool children. In India, lack of availability and affordability of oral health enhances the cost of treatment and care. Empowering community workers like Anganwadi workers (AWWs) in oral health, and providing basic oral health awareness to the mothers through them can be feasible model. So, the present study was conducted to evaluate the short-term impact of Oral Hygiene Training Package (OHTP) to AWWs on improving oral hygiene of preschool children. This before and after comparison field trial was done in Anganwadi centres (AWCs) of Chandigarh city, India. 534 children aged 36-72 months attending 21 AWCs were examined before and after imparting trainings to AWWs. OHTP was administered to AWWs, which consisted of power-point presentation and demonstrated the skills like proper brushing technique, plaque disclosure, flossing technique, gum massaging etc. The AWWs later imparted training to mothers in their respective AWCs. Post intervention data was collected after three months.Outcome measures were improvement in oral health status (plaque, debris, gingival health), oral habits (brushing, rinsing) and decrease in caries activity (Snyder test). Prevalence of dental caries was found to be 48.3%. Only 4.1% of the population reported brushing twice which increased significantly to 9.9% post-intervention (p = 0.000). There was a significant decrease in debris (78.3% to 54.1%), and stage-1 plaque (75.5 to 66.5%) in the oral cavity. Caries activity by Snyder's test decreased from 48.2% to 31.2% (p = 0.01) post-intervention. Controlled trials of using AWWs to improve oral hygiene appear to be justified. CTRI/2012/07/002786.

Surgery is succeeded by long-lasting state of relative peripheral insulin resistance, which is reduced by giving glucose infusion or oral carbohydrate-rich drinks immediate before operating instead of fasting. The aim of the present study was to investigate whether oral carbohydrate or carbohydrate with peptide drinks preoperatively instead of fasting would improve postoperative voluntary muscle strength, nutritional intake and ambulation, decrease postoperative fatigue, anxiety and discomfort, and reduce the endocrine response to surgery. Forty-eight patients were included and randomized into three groups to receive 2 x 400 ml of carbohydrate-rich drinks or to fast overnight and allowed only water. Voluntary grip and quadriceps strength, body composition, pulmonary function, VAS-score of eight parameters of wellbeing, muscle biopsies and insulin, glucagon, IGF-1 and free fatty acids were measured before and after the operation. The basic postoperative regimen for all groups were immediate oral nutrition and early enforced mobilization. Significant postoperative decrease in glycogen synthase activity in the muscle biopsies was reduced in the intervention groups, and in combination, the intervention groups had a less reduced quadriceps strength after one week (-10% vs. -16%, NS) and one month (-5% vs. -13%, P < 0.05). Minor changes in the endocrine response to surgery were found without differences between the groups, and there were no differences between the groups in ambulation time, nutritional intake or subjective measures of wellbeing.

To report experience with combined therapy using intracorporal injection (ICI) of alprostadil and oral phosphodiesterase 5 (PDE-5) inhibitors for the minimally invasive treatment of erectile dysfunction (ED) after radical prostatectomy (RP), as PDE-5 inhibitors are effective but a few patients may have a suboptimal response. In a retrospective study, 34 men (aged 46-66 years) had a nerve-sparing retropubic RP and subsequent ED. Patients were titrated on sildenafil citrate or vardenafil to maximum doses. All had a suboptimal response after a maximum of eight doses of oral therapy and were then treated with ICI therapy using 15 or 20 microg alprostadil. Erectile function was assessed with the Sexual Health Inventory for Men (SHIM). Of the 32 patients who continued combined therapy, 22 (68%) had an improvement in erectile function after ICI therapy, as assessed by the SHIM score. On follow-up, 36% of these patients used ICI therapy only intermittently, instead of regularly, as they felt that this was adequate enough for good results. PDE-5 oral pharmacotherapy is the most commonly used effective therapy for ED but may not be as effective in patients who have radical surgery; the addition of testosterone patches may have side-effects or be considered a risk in patients with a history of prostate cancer. The use of ICI therapy as an adjunct or maintenance therapy to their oral medication may be another alternative in these patients.

We identified factors associated with improved self-reported health status in a sample of people living with HIV/AIDS (PLWHA) following enrollment in oral health care. Data were collected from 1,499 enrollees in the Health Resources and Services Administration HIV/AIDS Bureau's Special Projects of National Significance Innovations in Oral Health Care Initiative. Data were gathered from 2007-2010 through in-person interviews at 14 sites; self-reported health status was measured using the SF-8™ Health Survey's physical and mental health summary scores. Utilization records of oral health-care services provided to enrollees were also obtained. Data were analyzed using general estimating equation linear regression. Between baseline and follow-up, we found that physical health status improved marginally while mental health status improved to a greater degree. For change in physical health status, a decrease in oral health problems and lack of health insurance were significantly associated with improved health status. Improved mental health status was associated with a decrease in oral health problems at the last available visit and no pain or distress in one's teeth or gums at the last available visit. For low-income PLWHA, engagement in a program to increase access to oral health care was associated with improvement in overall well-being as measured by change in the SF-8 Health Survey. These results contribute to the knowledge base about using the SF-8 to assess the impact of clinical interventions. For public health practitioners working with PLWHA, findings suggest that access to oral health care can help promote well-being for this vulnerable population.

Here, we investigated the formation and functional properties of self-assembled lecithin/chitosan nanoparticles (L/C NPs) loaded with insulin following insulin-phospholipid complex preparation, with the aim of developing a method for oral insulin delivery. Using a modified solvent-injection method, insulin-loaded L/C NPs were obtained by combining insulin-phospholipid complexes with L/C NPs. The nanoparticle size distribution was determined by dynamic light scattering, and morphologies were analyzed by cryogenic transmission electron microscopy. Fourier transform infrared spectroscopy analysis was used to disclose the molecular mechanism of prepared insulin-loaded L/C NPs. Fast ultrafiltration and a reversed-phase high-performance liquid chromatography assay were used to separate free insulin from insulin entrapped in the L/C NPs, as well as to measure the insulin-entrapment and drug-loading efficiencies. The in vitro release profile was obtained, and in vivo hypoglycemic effects were evaluated in streptozotocin-induced diabetic rats. Our results indicated that insulin-containing L/C NPs had a mean size of 180 nm, an insulin-entrapment efficiency of 94%, and an insulin-loading efficiency of 4.5%. Cryogenic transmission electron microscopy observations of insulin-loaded L/C NPs revealed multilamellar structures with a hollow core, encircled by several bilayers. In vitro analysis revealed that insulin release from L/C NPs depended on the L/C ratio. Insulin-loaded L/C NPs orally administered to streptozotocin-induced diabetic rats exerted a significant hypoglycemic effect. The relative pharmacological bioavailability following oral administration of L/C NPs was 6.01%. With the aid of phospholipid-complexation techniques, some hydrophilic peptides, such as insulin, can be successfully entrapped into L/C NPs, which could improve oral bioavailability, time-dependent release, and therapeutic activity.

Short bowel syndrome (SBS) is associated with gut barrier dysfunction. We examined effects of dietary glutamine (GLN) or oral antibiotics (ABX) on indexes of gut barrier function in a rat model of SBS. Adult rats underwent a 60% distal small bowel + proximal colonic resection (RX) or bowel transection (TX; control). Rats were pair fed diets with or without l-GLN for 20 days after operation. Oral ABX (neomycin, metronidazole, and polymyxin B) were given in some RX rats fed control diet. Stool secretory immunoglobulin A (sIgA) was measured serially. On day 21, mesenteric lymph nodes (MLN) were cultured for gram-negative bacteria. IgA-positive plasma cells in jejunum, stool levels of flagellin- and lipopolysaccharide (LPS)-specific sIgA, and serum total, anti-flagellin- and anti-LPS IgG levels were determined. RX caused gram-negative bacterial translocation to MLN, increased serum total and anti-LPS IgG and increased stool total sIgA. After RX, dietary GLN tended to blunt bacterial translocation to MLN (-29%, P = NS) and significantly decreased anti-LPS IgG levels in serum, increased both stool and jejunal mucosal sIgA and increased stool anti-LPS-specific IgA. Oral ABX eliminated RX-induced bacterial translocation, significantly decreased total and anti-LPS IgG levels in serum, significantly decreased stool total IgA and increased stool LPS-specific IgA. Partial small bowel-colonic resection in rats is associated with gram-negative bacterial translocation from the gut and a concomitant adaptive immune response to LPS. These indexes of gut barrier dysfunction are ameliorated or blunted by administration of dietary GLN or oral ABX, respectively. Dietary GLN upregulates small bowel sIgA in this model.

Apo AIV and Citrulline Plasma Concentrations in Short Bowel Syndrome Patients: The Influence of Short Bowel Anatomy.

Parenteral nutrition (PN) dependence in short bowel syndrome (SBS) patients is linked to the functionality of the remnant small bowel (RSB). Patients may wean off PN following a period of intestinal adaptation that restores this functionality. Currently, plasma citrulline is the standard biomarker for monitoring intestinal functionality and adaptation. However, available studies reveal that the relationship the biomarker with the length and function of the RSB is arguable. Thus, having additional biomarkers would improve pointing out PN weaning. By measuring concomitant changes in citrulline and the novel biomarker apolipoprotein AIV (Apo AIV), as well as taking into account the anatomy of the RSB, this exploratory study aims to a better understanding of the intestinal adaptation process and characterization of the SBS patients under PN. Thirty four adult SBS patients were selected and assigned to adapted (aSBS) and non-adapted (nSBS) groups after reconstructive surgeries. Remaining jejunum and ileum lengths were recorded. The aSBS patients were either on an oral diet (ORAL group), those with intestinal insufficiency, or on oral and home parenteral nutrition (HPN group), those with chronic intestinal failure. Apo AIV and citrulline were analyzed in plasma samples after overnight fasting. An exploratory ROC analysis using citrulline as gold standard was performed. Biomarkers, Apo AIV and citrulline showed a significant correlation with RSBL in aSBS patients. In jejuno-ileocolic patients, only Apo AIV correlated with RSBL (rb = 0.54) and with ileum length (rb = 0.84). In patients without ileum neither biomarker showed any correlation with RSBL. ROC analysis indicated the Apo AIV cut-off value to be 4.6 mg /100 mL for differentiating between the aSBS HPN and ORAL groups. Therefore, in addition to citrulline, Apo AIV can be set as a biomarker to monitor intestinal adaptation in SBS patients. As short bowel anatomy is shown to influence citrulline and Apo AIV plasma values, both biomarkers complement each other furnishing a new insight to manage PN dependence.

Promoting oral health among the inner city homeless: a community-academic partnership.

Oral health care resources for the homeless are scarce, underfunded, and generally inadequate to meet the oral health needs of this population. The purpose of this program was to improve oral health among the urban homeless in a faith-based inner city mission through education, screening, and improved access to oral health care. The program provided for expanded delivery of oral health care services to the homeless while preparing students in the health professions for community-based practice with at-risk and vulnerable populations. By proactively addressing oral health needs through prevention and earlier diagnosis and treatment, morbidity, quality of life, and cost can be positively affected. Innovative, cross-disciplinary, community delivery models that involve key stakeholders at all levels are needed to address the oral health needs of the homeless and underserved adequately.

Family relationships as an explanatory variable in childhood dental caries: a systematic review of measures.

It is widely acknowledged that parental beliefs (self-efficacy) about oral health and parental oral health-related behaviours play a fundamental role in the establishment of preventative behaviours that will mitigate against the development of childhood dental caries. However, little attention has been given to the wider perspective of family functioning and family relationships on child oral health. For oral health researchers, exploration of this association requires the use of reliable, valid and appropriate assessment tools to measure family relationships. In order to promote methodologically sound research in oral health, this systematic review aims to provide a guide on self-report psychometric measures of family functioning that may be suitable to utilize when exploring childhood dental caries. This systematic review has identified 29 self-report measures of family functioning and evaluated them in terms of their psychometric support, constructs measured and potential utility for oral health research. The majority of the measures reported adequate levels of reliability and construct validity. Construct evaluation of the measures identified five core domains of family functioning, namely 'communication', 'cohesion/engagement', 'control', 'involvement' and 'authoritative/rigid parenting style'. The constructs were subsequently evaluated with respect to their potential relevance to child oral health. Herewith this review provides a framework to guide future research to explore family functioning in furthering our understanding of the development of childhood dental caries. © 2013 S.

The purpose of this study was to evaluate the effectiveness of oral reading as a teaching technique for improving reading comprehension of 11 Educable Mentally Handicapped or Severe Learning Disabled adolescents. Students were tested on their ability to answer comprehension questions from a short factual article. Comprehension improved following the oral reading for students with a reading grade equivalent of less than 5.5 (measured from the Wide Range Achievement Test) but not for those students having a grade equivalent of greater than 5.5. This association was statistically significant (p = less than .01). Oral reading appeared to improve comprehension among the poorer readers but not for readers with moderately high ability.

Increasing the number of inter-arch contacts improves mastication in adults with Down syndrome: a prospective controlled trial.

Feeding difficulties due to their condition have been widely described for babies, children and adults with Down syndrome (DS). A previous study demonstrated that, compared with wearing a placebo appliance, wearing an occlusal appliance increased inter-arch dental contacts, improved the oral health status of adults with DS and normalised their mandibular rest position. This longitudinal prospective controlled trial aimed to evaluate whether increasing inter-arch contacts in adults with DS would lead to improved masticatory efficiency. Fourteen subjects with DS (mean age±SD: 28.5±9.3years) and twelve controls without DS (24.6±1.0years) were video recorded while chewing samples of carrot and peanuts with and without an oral appliance that was designed to equalise the number of posterior functional units (PFUs) in both groups. Three parameters were collected during mastication for 15cycles and until swallowing: food refusals, food bolus granulometry (D50) and kinematic parameters of the chewing process (number of cycles, chewing duration and cycle frequency within the chewing sequence). In the DS group, increasing the number of PFUs led to a decrease in bolus particle size, to fewer masticatory cycles needed to produce a bolus ready for swallowing and to a decrease in the occurrence of food refusal, while mean chewing frequency did not vary. In the control group, bolus granulometry and chewing time increased with appliance wear while mean chewing frequency decreased. These changes clearly indicate a functional improvement in subjects with DS. This study also demonstrated a causal relationship between the number of functional pairs of posterior teeth and improved mastication. Any evaluation of feeding behaviour in persons with DS should consider inter-arch dental contacts as an explicative variable for feeding problems and their nutritional and respiratory consequences.

Surgical site infection is a major cause of morbidity after colorectal resections. Despite evidence that preoperative oral antibiotics with mechanical bowel preparation reduce surgical site infection rates, the use of oral antibiotics is decreasing. Currently, the administration of oral antibiotics is controversial and considered ineffective without mechanical bowel preparation. The aim of this study is to examine the use of mechanical bowel preparation and oral antibiotics and their relationship to surgical site infection rates in a colorectal Surgical Care Improvement Project cohort. This retrospective study used Veterans Affairs Surgical Quality Improvement Program preoperative risk and surgical site infection outcome data linked to Veterans Affairs Surgical Care Improvement Project and Pharmacy Benefits Management data. Univariate and multivariable models were performed to identify factors associated with surgical site infection within 30 days of surgery. This study was conducted in 112 Veterans Affairs hospitals. Included were 9940 patients who underwent elective colorectal resections from 2005 to 2009. The primary outcome measured was the incidence of surgical site infection. Patients receiving oral antibiotics had significantly lower surgical site infection rates. Those receiving no bowel preparation had similar surgical site infection rates to those who had mechanical bowel preparation only (18.1% vs 20%). Those receiving oral antibiotics alone had an surgical site infection rate of 8.3%, and those receiving oral antibiotics plus mechanical bowel preparation had a rate of 9.2%. In adjusted analysis, the use of oral antibiotics alone was associated with a 67% decrease in surgical site infection occurrence (OR=0.33, 95% CI 0.21-0.50). Oral antibiotics plus mechanical bowel preparation was associated with a 57% decrease in surgical site infection occurrence (OR=0.43, 95% CI 0.34-0.55). Timely administration of parenteral antibiotics (Surgical Care Improvement Project-1) had a modest protective effect, with no effect observed for other Surgical Care Improvement Project measures. Hospitals with higher rates of oral antibiotics use had lower surgical site infection rates (R = 0.274, p < 0.0001). Determination of the use of oral antibiotics and mechanical bowel preparation is based on retrospective prescription data, and timing of actual administration cannot be determined. Use and type of preoperative bowel preparation varied widely. These results strongly suggest that preoperative oral antibiotics should be administered for elective colorectal resections. The role of oral antibiotics independent of mechanical bowel preparation should be examined in a prospective randomized trial.

Effectiveness of iPad computerized writing instruction was evaluated for 4 th to 9 th graders ( n =35) with diagnosed specific learning disabilities (SLDs) affecting writing: dysgraphia (impaired handwriting), dyslexia (impaired spelling), and oral and written language learning disability (OWL LD) (impaired syntax composing). Each of the 18 two-hour lessons had multiple learning activities aimed at improving subword - (handwriting), word - (spelling), and syntax - (sentence composing) level language skills by engaging all four language systems (listening, speaking, reading, and writing) to create a functional writing system. To evaluate treatment effectiveness, normed measures of handwriting, spelling, and composing were used with the exception of one non-normed alphabet writing task. Results showed that the sample as a whole improved significantly from pretest to posttest in three handwriting measures, four spelling measures, and both written and oral syntax construction measures. All but oral syntax was evaluated with pen and paper tasks, showing that the computer writing instruction transferred to better writing with pen and paper. Performance on learning activities during instruction correlated with writing outcomes; and individual students tended to improve in the impaired skill associated with their diagnosis. Thus, although computers are often used in upper elementary school and middle school in the United States (US) for accommodations (alternatives to pen and paper) for students with persisting SLDs affecting writing, this study shows computers can also be used for Tier 3 instruction to improve the writing skills of students in grades 4 to 9 with history of persisting writing disabilities.

2008-01-01

Dysphagia, or difficulty swallowing, often occurs secondary to conditions such as stroke, head injury or progressive disease, many of which increase in frequency with advancing age. Sarcopenia, the gradual loss of muscle bulk and strength, can place older individuals at greater risk for dysphagia. Data are reported for three older participants in a pilot trial of a tongue-pressure training therapy. During the experimental therapy protocol, participants performed isometric strength exercises for the tongue as well as tongue pressure accuracy tasks. Biofeedback was provided using the Iowa Oral Performance Instrument (IOPI), an instrument that measures tongue pressure. Treatment outcome measures show increased isometric tongue strength, improved tongue pressure generation accuracy, improved bolus control on videofluoroscopy, and improved functional dietary intake by mouth. These preliminary results indicate that, for these three adults with dysphagia, tongue-pressure training was beneficial for improving both instrumental and functional aspects of swallowing. The experimental treatment protocol holds promise as a rehabilitative tool for various dysphagia populations.

Maxillary defects are usually rehabilitated by a prosthetic obturator. This study aimed to evaluate the functioning of obturators prosthesis in patients with unilateral defects after maxillectomy. Of 49 patients, 28 underwent to maxillectomy as a result of tumor ablative surgery, and acquired unilateral maxillary defects. Evaluation of the function was performed by applying the Obturator Functional Scale (OFS). From a total of 49 patients, 28 were treated as follows: 9 with a conventional retained obturator prosthesis (COP), 11 (39%) with an enhanced retentive obturator prosthesis with stud attachment (POP) and 8 (28%) with an enhanced retentive obturator prosthesis with magnetic attachment (POM). The mean OFS score was 80. Scores on functions of speech, swallowing and chewing reached statistical significances (p<0.05) among these three subgroups. Comparing COP and MOP groups, the scores of OFS in the domains of "Speech-ability to speak in public" and "Swallowing-leakage with liquids" were significantly higher in AOP group. Comparing COP group, the scores of OFS in "Swallowing-leakage with solid" and "Chewing/eating" domains were increased significantly (p<0.05) both in MOP and AOP groups. Obturator prosthesis improves oral function of patients after maxillary defects; the retention of the obturator prosthesis enhanced by the addition of attachments showed more benefits in oral function.

Improving the oral health of refugees and asylum seekers is a global priority, yet little is known about the overall burden of oral diseases and their causes for this population. To synthesize available evidence on the oral health of, and access to oral health care by this population. Using a scoping review methodology, we retrieved 3321 records from eight databases and grey literature; 44 publications met the following inclusion criteria: empirical research focused on refugees and/or asylum seekers' oral health, published between 1990 and 2014 in English, French, Italian, Portuguese, or Spanish. Analysis included descriptive and thematic analysis, as well as critical appraisal using the Critical Appraisal Skills Programme (CASP) criteria for quantitative and qualitative studies. The majority of publications (86 %) were from industrialized countries, while the majority of refugees are resettled in developing countries. The most common study designs were quantitative (75 %). Overall, the majority of studies (76 %) were of good quality. Studies mainly explored oral health status, knowledge and practices; a minority (9 %) included interventions. The refugee populations in the studies showed higher burden of oral diseases and limited access to oral health care compared to even the least privileged populations in the host countries. Minimal strategies to improve oral health have been implemented; however, some have impressive outcomes. Oral health disparities for this population remain a major concern. More research is needed on refugees in developing countries, refugees residing in refugee camps, and interventions to bridge oral health disparities. This review has utility for policymakers, practitioners, researchers, and other stakeholders working to improve the oral health of this population.

Background: Oral contraceptives are commonly used by women athletes. However, their effect on athletic performance is unclear. Objectives: To examine the effects of a moderate dose, triphasic oral contraceptive on measures of athletic performance in highly trained women athletes. Methods: This is a double blind, placebo controlled trial in 14 women with ovulatory menstrual cycles and maximal aerobic capacity (VO2MAX) ≥50 ml/kg/min. Four measures of athletic performance were tested: VO2MAX, anaerobic capacity (anaerobic speed test), aerobic endurance (time to fatigue at 90% of VO2MAX), and isokinetic strength (Cybex II dynamometer). Height, weight, and six skinfold measurements were also recorded. All these observational tests were completed during both the follicular and mid-luteal phases of an ovulatory menstrual cycle. Cycle phases were confirmed by assaying plasma oestradiol and progesterone. Participants were subsequently randomly assigned to either a tricyclic oral contraceptive or placebo and retested in identical fashion (oral contraceptive phase). Results: Absolute and relative changes in VO2MAX from follicular to oral contraceptive phase decreased in the oral contraceptive group by 4.7%, whereas the placebo group showed a slight increase (+1.5%) over the same time period. Two of the women taking oral contraceptive had decreases of 4 and 9 ml/kg/min. In contrast, most women in the placebo group improved or maintained VO2MAX. There was also a significant increase in the sum of skinfolds in women taking oral contraceptive compared with those taking placebo (p<0.01). There were no significant changes in other physiological variables (maximum ventilation, heart rate, respiratory exchange ratio, packed cell volume) or measures of performance (anaerobic speed test, aerobic endurance, isokinetic strength) as a function of oral contraceptive treatment. Conclusions: The decrease in VO2MAX that occurs when oral contraceptive is taken may influence elite sporting performance in some women. Further studies are required to determine the mechanisms of this change. PMID:12893716

Peyronie’s disease (PD) is a connective tissue disorder involving the tunica albuginea of the corpora cavernosa of the penis. We have published several studies describing a “combined therapy” for PD patients, but the present study aims to clearly demonstrate how the association between various antioxidants in PD treatment can significantly increase the likelihood of therapeutic success. We used the following substances: silymarin, ginkgo biloba, vitamin E, bilberry, topical diclofenac sodium, and pentoxifylline (PTX). We analyzed the therapeutic impact and possible side effects of one or more antioxidants in patients with early-stage PD. To clearly prove that it is possible to achieve better results when combining more than one agent, we designed this study with five treatment groups, corresponding, respectively, to the administration of a single oral antioxidant; two oral antioxidants; three oral antioxidants; five oral antioxidants + local diclofenac; and five oral antioxidants + local diclofenac + PTX by perilesional injection. One hundred and twenty patients were assigned to five groups of treatment designed according to the abovementioned study aim. Outcomes after 6 months of treatment showed that combined antioxidant therapy is effective in treating PD. Statistical analysis showed significant differences between the treatment groups with regard to: improvement and disappearance of penile pain; percentage of reduction in the volume of penile plaque; reduction in penile curvature; recovery of erectile function in patients with erectile dysfunction; increase in the International Index of Erectile Function score; and reduction of psychosexual impact. Furthermore, we observed that the clinical efficacy of combined therapy is greater when topical use of diclofenac gel and perilesional injection of PTX are added to oral treatment with more than one antioxidant. Although several articles have already been published reporting the effectiveness of combined treatment in PD, this is the first study clearly proving how, as the number of substances used in treatment rises, a proportionally greater therapeutic effect is achieved.

To provide a preliminary clinical profile of the resolution and outcomes of oral-motor impairment and swallowing function in a group of paediatric dysphagia patients post-traumatic brain injury (TBI). To document the level of cognitive impairment parallel to the return to oral intake, and to investigate the correlation between the resolution of impaired swallow function versus the resolution of oral-motor impairment and cognitive impairment. Thirteen children admitted to an acute care setting for TBI. A series of oral-motor (Verbal Motor Production Assessment for Children, Frenchay Dysarthria Assessment, Schedule for Oral Motor Assessment) and swallowing (Paramatta Hospital's Assessment for Dysphagia) assessments, an outcome measure for swallowing (Royal Brisbane Hospital's Outcome Measure for Swallowing), and a cognitive rating scale (Rancho Level of Cognitive Functioning Scale). Across the patient group, oral-motor deficits resolved to normal status between 3 and 11 weeks post-referral (and at an average of 12 weeks post-injury) and swallowing function and resolution to normal diet status were achieved by 3-11 weeks post-referral (and at an average of 12 weeks post-injury). The resolution of dysphagia and the resolution of oral-motor impairment and cognitive impairment were all highly correlated. The provision of a preliminary profile of oral-motor functioning and dysphagia resolution, and data on the linear relationship between swallowing impairment and cognition, will provide baseline information on the course of rehabilitation of dysphagia in the paediatric population post-TBI. Such data will contribute to more informed service provision and rehabilitation planning for paediatric patients post-TBI.

Background: Caloric restriction alone has been shown to improve insulin action and fasting glucose metabolism; however, the mechanism by which this occurs remains uncertain. Objective: We sought to quantify the effect of caloric restriction on β cell function and glucose metabolism in people with type 2 diabetes. Methods: Nine subjects (2 men, 7 women) with type 2 diabetes [BMI (in kg/m2): 40.6 ± 1.4; age: 58 ± 3 y; glycated hemoglobin: 6.9% ± 0.2%] were studied using a triple-tracer mixed meal after withdrawal of oral diabetes therapy. The oral minimal model was used to measure β cell function. Caloric restriction limited subjects to a pureed diet (<900 kcal/d) for the 12 wk of study. The studies were repeated after 6 and 12 wk of caloric restriction. Results: Fasting glucose concentrations decreased significantly from baseline after 6 wk of caloric restriction with no further reduction after a further 6 wk of caloric restriction (9.8 ± 1.3, 5.9 ± 0.2, and 6.2 ± 0.3 mmol/L at baseline and after 6 and 12 wk of caloric restriction, respectively; P = 0.01) because of decreased fasting endogenous glucose production (EGP: 20.4 ± 1.1, 16.2 ± 0.8, and 17.4 ± 1.1 μmol · kg−1 · min−1 at baseline and after 6 and 12 wk of caloric restriction, respectively; P = 0.03). These changes were accompanied by an improvement in β cell function measured by the disposition index (189 ± 51, 436 ± 68, and 449 ± 67 10−14 dL · kg−1 · min−2 · pmol−1 at baseline and after 6 and 12 wk of caloric restriction, respectively; P = 0.01). Conclusions: Six weeks of caloric restriction lowers fasting glucose and EGP with accompanying improvements in β cell function in people with type 2 diabetes. An additional 6 wk of caloric restriction maintained the improvement in glucose metabolism. This trial was registered at clinicaltrials.gov as NCT01094054. PMID:26246321

2005-05-01

This review presents an overview of studies concerning oral formulations intended for site-specific drug delivery to the colon with pectin as the main excipient. The biological aspects covered include gastrointestinal transit and the enzymatic degradation of pectin. Scintigraphic methods demonstrating the functionality of pectin formulations are discussed. The main focus is on the various formulations reported, including matrix tablets, multiparticulate formulations as pellets and hydrogel beads, and pectin-based coatings. Also included is an evaluation of common excipients employed to improve colon specificity by crosslinking or increasing the hydrophobicity. Finally, properties of the pectin molecules that are important for successful formulations are examined. The conclusion is that the studies found in the literature provide an excellent platform for the development of pectin-based colon delivery systems.

Ankyloglossia, or tongue-tie, is a congenital condition characterized by a short, thickened, or abnormally tight lingual frenulum. This anomaly can cause a varying degree of reduced tongue mobility and has been associated with functional limitations including breastfeeding difficulties, atypical swallowing habits, speech articulation problems, mechanical problems such as inability to clean the oral cavity, and psychosocial stress. In this article, we report a 50-year-old female patient with tongue-tie having difficulty in speech and maintenance of oral hygiene due to high attachment of lingual frenum. The patient was managed by frenectomy by conventional method (scalpel and blade) under local anesthesia as an outpatient procedure without any complications. She later required speech therapy lessons for improvement of speech.

To study the outcome of intensified mechanical oral hygiene compared with the effect of an adjunctive antibacterial mouth rinse on plaque and gingivitis in elderly people. In a randomized, single-blind, 6-month controlled clinical study, 106 subjects, 55 years or older, were divided into four groups: (I) Participants were instructed on improved mechanical oral hygiene, including interdental hygiene; (II) subjects used an antibacterial mouth rinse containing amine and stannous fluoride in addition to their usual oral hygiene practices; (III) both intensive mechanical and antibacterial measures were combined; and (IV) a control group with no specific regimen. Gingivitis and plaque were examined. After 6 months, both plaque and gingivitis scores were significantly lower than at baseline in all groups. Reductions in gingivitis differed significantly between the control group and all other groups but not between the three intervention groups. Only groups with improved mechanical oral hygiene showed significant improvements in plaque scores compared with control. Intensive mechanical oral hygiene resulted in greater plaque reduction than the combination of an antibacterial rinse and usual oral hygiene procedures. Gingivitis was reduced by both intensive oral hygiene and use of the amine/stannous fluoride rinse. Combining intensive mechanical oral hygiene with the antibacterial rinse did not result in further gingivitis reduction.

Very little is known about the potential relationship between welfare state regimes and oral health. This study assessed the oral health of adults in a range of European countries clustered by welfare regimes according to Ferrera's typology and the complementary Eastern type. We analysed data from Eurobarometer wave 72.3, a cross-sectional survey of 31 European countries carried out in 2009. We evaluated three self-reported oral health outcomes: edentulousness, no functional dentition (<20 natural teeth), and oral impacts on daily living. Age-standardized prevalence rates were estimated for each country and for each welfare state regime. The Scandinavian regime showed lower prevalence rates for all outcomes. For edentulousness and no functional dentition, there were higher prevalence rates in the Eastern regime but no significant differences between Anglo-Saxon, Bismarckian, and Southern regimes. The Southern regime presented a higher prevalence of oral impacts on daily living. Results by country indicated that Sweden had the lowest prevalences for edentulousness and no functional dentition, and Denmark had the lowest prevalence for oral impacts. The results suggest that Scandinavian welfare states, with more redistributive and universal welfare policies, had better population oral health. Future research should provide further insights about the potential mechanisms through which welfare-state regimes would influence oral health. PMID:23659239

To extend previous observations by investigating if differences exist in time to initiation or to recovery of total oral intake in patients with acquired brain injury assessed by either Facial-Oral Tract Therapy (F.O.T.T.) or Fibreoptic Endoscopic Evaluation of Swallowing (FEES) and to investigate whether other factors influence these outcomes. Randomized controlled trial. One hundred and nineteen patients with dysphagia in inpatient neurorehabilitation were randomized. The main outcome was time to maximum on the Functional Oral Intake Scale. There was no difference in time to initiation or recovery of total oral intake using F.O.T.T. or FEES. Oral intake was initiated for 42% on admission and 92% at discharge; 2.5% of the patients were on total oral intake within 24 hours of admission and 37% at discharge. The likelihood of recovery to total oral intake before discharge was found to depend on age, Functional Independence Measure score, length of stay and number of dysphagia interventions. There was no significant difference in time to initiation and recovery of total oral intake before discharge, whether assessed by F.O.T.T. or FEES, indicating that an instrumental assessment is unnecessary for standard evaluation. Age, functional independence and length of stay had a significant influence.

The aim of the study was to determine the efficiency of the applied preventive measures during pregnancy and to improve oral health status to pregnant women. Oral health status of 180 pregnant women was determined according to WHO criteria (WHO: Basic methods, 1997). Dental caries prevalence, DMF-T and DMF-S were evaluated. Gingival status was estimated according to Silness-Loe (GI) index. Women were asked about tooth brushing frequency; oral hygiene was evaluated according to Green-Vermilion (OHI-S) index. Participants were divided into test (89) and control (91) groups. During pregnancy, the following preventive measures were applied to the test group: fluoride varnish applications, mouthrinsing with 0.12% chlorhexine digluconate, professional oral hygiene. Oral health status was evaluated three times during pregnancy. Reduction in dental caries increment of the test group was 56.25% in comparison with the control group. The periodontal status has improved, oral hygiene index (OHI-S) has decreased from 1.48+/-0.05 to 0.94+/-0.06 in the test group, and from 1.49+/-0.06 to 1.9+/-0.06 in the control group. Results of the study showed that selected dental caries preventive measures were effective and significantly improved women's oral health during pregnancy.

Oral Administration and Detection of a Near-Infrared Molecular Imaging Agent in an Orthotopic Mouse Model for Breast Cancer Screening

PubMed Central

2018-01-01

Molecular imaging is advantageous for screening diseases such as breast cancer by providing precise spatial information on disease-associated biomarkers, something neither blood tests nor anatomical imaging can achieve. However, the high cost and risks of ionizing radiation for several molecular imaging modalities have prevented a feasible and scalable approach for screening. Clinical studies have demonstrated the ability to detect breast tumors using nonspecific probes such as indocyanine green, but the lack of molecular information and required intravenous contrast agent does not provide a significant benefit over current noninvasive imaging techniques. Here we demonstrate that negatively charged sulfate groups, commonly used to improve solubility of near-infrared fluorophores, enable sufficient oral absorption and targeting of fluorescent molecular imaging agents for completely noninvasive detection of diseased tissue such as breast cancer. These functional groups improve the pharmacokinetic properties of affinity ligands to achieve targeting efficiencies compatible with clinical imaging devices using safe, nonionizing radiation (near-infrared light). Together, this enables development of a “disease screening pill” capable of oral absorption and systemic availability, target binding, background clearance, and imaging at clinically relevant depths for breast cancer screening. This approach should be adaptable to other molecular targets and diseases for use as a new class of screening agents. PMID:29696981

Orthodontic treatment for disabled children: a survey of parents’ attitudes and overall satisfaction

PubMed Central

2014-01-01

Background Many patients with disability require orthodontic treatment (OT) to achieve adequate oral function and aesthetic appearance. The cooperation of disabled patients and of their parents is central to the success of OT, as treatment can involve ethical dilemmas. The aim of this study was to analyze the motivation, expectations and overall satisfaction with OT among parents of patients with disabilities. Methods The parents of 60 disabled Spanish children with physical, mental and/or sensory impairment undergoing OT were surveyed on attitudes to OT and level of satisfaction with the outcomes. The survey consisted of 23 questions in 4 sections: attitude and adaptation, benefits, adverse effects, and level of satisfaction after completion of OT. A control group formed of the parents of 60 healthy children undergoing OT at the same institution were also surveyed. Results Parents of disabled children undergoing OT showed a high level of motivation and they are willing to collaborate in oral hygiene procedures. Adaptation to the removable appliances was poorer in disabled children but adaptation to fixed appliances was excellent. OT can provide a marked improvement in quality of life, social relationships and oral functionality in disabled children. Conclusions Among parents of disabled children undergoing OT, the perceived level of overall satisfaction was very high and expectations were often exceeded. PMID:25096027

Quality of life is negatively affected in children with food allergy. Oral immunotherapy is an approach to food allergy that leads to patient desensitization by administering gradually increasing amounts of a given food allergen. The aim of this pilot study is to evaluate how oral immunotherapy affects quality of life in children allergic to cow milk proteins. Thirty children (aged 3-12 years) with cow milk allergy were recruited. Their parents were provided with a validated disease specific quality of life questionnaire (the food allergy quality of life questionnaire -- parent form, FAQLQ-PF) before and again 2 months after completing an oral immunotherapy protocol with cow milk. A significant improvement in all the investigated domains -- emotional impact, food anxiety and social and dietary limitations -- was found. The separate analysis of the different age groups demonstrated that the emotional impact and the food-related anxiety improved in children older than 4, while the social domains improved in each age group. In this pilot experience, oral immunotherapy significantly improves quality of life in children with cow milk allergy. The improvement seems particularly evident in children over 4 years old, who are most likely to benefit from the oral immunotherapy approach. Further placebo-controlled studies are needed to confirm these preliminary results.

Osteogenesis imperfecta is caused by a genetic defect resulting in an abnormal type I collagen bone matrix which typically results in multiple fractures with little or no trauma. Bisphosphonates are used in an attempt to increase bone mineral density and reduce these fractures in people with osteogenesis imperfecta. This is an update of a previously published Cochrane Review. To assess the effectiveness and safety of bisphosphonates in increasing bone mineral density, reducing fractures and improving clinical function in people with osteogenesis imperfecta. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Inborn Errors of Metabolism Trials Register which comprises references identified from comprehensive electronic database searches, handsearches of journals and conference proceedings. We additionally searched PubMed and major conference proceedings.Date of the most recent search of the Cochrane Cystic Fibrosis and Genetic Disorders Group's Inborn Errors of Metabolism Register: 28 April 2016. Randomised and quasi-randomised controlled trials comparing bisphosphonates to placebo, no treatment, or comparator interventions in all types of osteogenesis imperfecta. Two authors independently extracted data and assessed the risk of bias of the included trials. Fourteen trials (819 participants) were included. Overall, the trials were mainly at a low risk of bias, although selective reporting was an issue in several of the trials. Data for oral bisphosphonates versus placebo could not be aggregated; a statistically significant difference favouring oral bisphosphonates in fracture risk reduction and number of fractures was noted in two trials. No differences were reported in the remaining three trials which commented on fracture incidence. Five trials reported data for spine bone mineral density; all found statistically significant increased lumbar spine density z scores for at least one time point studied. For intravenous bisphosphonates versus placebo, aggregated data from two trials showed no statistically significant difference for the number of participants with at least one fracture, risk ratio 0.56 (95% confidence interval 0.30 to 1.06). In the remaining trial no statistically significant difference was noted in fracture incidence. For spine bone mineral density, no statistically significant difference was noted in the aggregated data from two trials, mean difference 9.96 (95% confidence interval -2.51 to 22.43). In the remaining trial a statistically significant difference in mean per cent change in spine bone mineral density z score favoured intravenous bisphosphonates at six and 12 months. Data describing growth, bone pain, and functional outcomes after oral or intravenous bisphosphonate therapy, or both, as compared to placebo were incomplete among all studies, but do not show consistent improvements in these outcomes. Two studies compared different doses of bisphosphonates. No differences were found between doses when bone mineral density, fractures, and height or length z score were assessed. One trial compared oral versus intravenous bisphosphonates and found no differences in primary outcomes. Two studies compared the intravenous bisphosphonates zoledronic acid and pamidronate. There were no significant differences in primary outcome. However, the studies were at odds as to the relative benefit of zoledronic acid over pamidronate for lumbosacral bone mineral density at 12 months. Bisphophonates are commonly prescribed to individuals with osteogenesis imperfecta. Current evidence, albeit limited, demonstrates oral or intravenous bisphosphonates increase bone mineral density in children and adults with this condition. These were not shown to be different in their ability to increase bone mineral density. It is unclear whether oral or intravenous bisphosphonate treatment consistently decreases fractures, though multiple studies report this independently and no studies report an increased fracture rate with treatment. The studies included here do not show bisphosphonates conclusively improve clinical status (reduce pain; improve growth and functional mobility) in people with osteogenesis imperfecta. Given their current widespread and expected continued use, the optimal method, duration of therapy and long-term safety of bisphosphonate therapy require further investigation. In addition, attention should be given to long-term fracture reduction and improvement in quality of life indicators.

The aim of this study was to assess functional and esthetic satisfaction plus evaluate changes in oral health-related quality of life (OHRQoL) using the Oral Health Impact Profile (OHIP-14) after insertion of a metal-ceramic (MC-FDP) or a veneered zirconia all-ceramic (AC-FDP) posterior three-unit fixed dental prosthesis (FDP). Additionally, patients' and professionals' esthetic evaluations were compared. A convenience sample of 34 patients was randomized to receive a MC-FDP (n = 17) or an AC-FDP (n = 17). Patients were assessed using the OHIP-14 and also answered a questionnaire regarding satisfaction with function and esthetics using visual analog scales (VAS) before treatment and after 2 weeks, after 3 months, and after 1, 2, and 3 years. A fully dentate control group (n = 20) was also assessed using the OHIP-14. The operator and another observer evaluated the esthetics of the FDPs using VAS. The patients assessed the two FDP types similarly for all parameters. In contrast, there was a statistically significant difference in OHIP-14 results between the treated patients and the control group before treatment. After treatment, a statistically significant improvement in OHIP-14 was observed at all examinations. Patients were highly satisfied with the function and esthetics of the FDPs. The overall satisfaction with esthetics was statistically significantly higher among the patients than among the professionals at three out of five examinations. The patients experienced improved OHRQoL and increased satisfaction with function and esthetics after receiving a posterior three-unit FDP. No important differences were observed between the two types of FDPs when evaluated by the patient or the professionals.

Use of lectin-functionalized particles for oral immunotherapy

Immunotherapy, in recent times, has found its application in a variety of immunologically mediated diseases. Oral immunotherapy may not only increase patient compliance but may, in particular, also induce both systemic as well as mucosal immune responses, due to mucosal application of active agents. To improve the bioavailability and to trigger strong immunological responses, recent research projects focused on the encapsulation of drugs and antigens into polymer particles. These particles protect the loaded antigen from the harsh conditions in the GI tract. Furthermore, modification of the surface of particles by the use of lectins, such as Aleuria aurantia lectin, wheatgerm agglutinin or Ulex europaeus-I, enhances the binding to epithelial cells, in particular to membranous cells, of the mucosa-associated lymphoid tissue. Membranous cell-specific targeting leads to an improved transepithelial transport of the particle carriers. Thus, enhanced uptake and presentation of the encapsulated antigen by antigen-presenting cells favor strong systemic, but also local, mucosal immune responses. PMID:22834202

Condition-specific Quality of Life Assessment at Each Stage of Class III Surgical Orthodontic Treatment -A Prospective Study.

Surgical orthodontic treatment has been reported to improve oral health-related quality of life (OHRQL). Such treatment comprises three stages: pre-surgical orthodontic treatment; orthognathic surgery; and post-surgical orthodontic treatment. Most studies have focused on change in OHRQL between before and after surgery. However, it is also necessary to evaluate OHRQL at the pre-surgical orthodontic treatment stage, as it may be negatively affected by dental decompensation compared with at pre-treatment. The purpose of this prospective study was to investigate the influence of surgical orthodontic treatment on QOL by assessing change in condition-specific QOL at each stage of treatment in skeletal class III cases. Twenty skeletal class III patients requiring surgical orthodontic treatment were enrolled in the study. Each patient completed the Orthognathic Quality of Life Questionnaire (OQLQ), which was developed for patients with dentofacial deformity. Its items are grouped into 4 domains: "social aspects of dentofacial deformity"; "facial esthetics"; "oral function"; and "awareness of dentofacial esthetics". The questionnaire was completed at the pre-treatment, pre-surgical orthodontic treatment, and post-surgical orthodontic treatment stages. The results revealed a significant worsening in scores between at pre-treatment and pre-surgical orthodontic treatment in the domains of facial esthetics and oral function (p<0.01), and between at pre-surgical orthodontic and post-surgical orthodontic treatment in all domains except awareness of dentofacial esthetics (p<0.05, p<0.01). A significant correlation was observed between a negative change in overjet and worsening OQLQ scores at the pre-surgical orthodontic treatment stage. Significant correlations were also observed between improvement in upper and lower lip difference, soft tissue pogonion protrusion, and ANB angle and improvement in OQLQ scores at the post-surgical orthodontic treatment stage. These results indicate that morphologic change influences OHRQL in patients undergoing surgical orthodontic treatment not only after surgery, but also during pre-surgical orthodontic treatment.

Increased intestinal epithelial barrier function damages caused by early weaning stress have adverse effects on swine health and feed utilization efficiency. Probiotics have emerged as the promising antibiotic alternatives used for intestinal barrier function damage prevention. Our previous data showed that Lactobacillus frumenti was identified as a predominant Lactobacillus in the intestinal microbiota of weaned piglets. However, whether the intestinal epithelial barrier function in piglets was regulated by L. frumenti is still unclear. Here, piglets received a PBS vehicle or PBS suspension (2 ml, 108 CFU/ml) containing the L. frumenti by oral gavage once a day during the period of 6–20 days of age prior to early weaning. Our data demonstrated that oral administration of L. frumenti significantly improved the intestinal mucosal integrity and decreased the serum endotoxin and D-lactic acid levels in early-weaned piglets (26 days of age). The intestinal tight junction proteins (including ZO-1, Occludin, and Claudin-1) were significantly up-regulated by L. frumenti administration. The serum immunoglobulin G (IgG) levels, intestinal secretory immunoglobulin A (sIgA) levels, and interferon-γ (IFN-γ) levels were significantly increased by L. frumenti administration. Furthermore, our data revealed that oral administration of L. frumenti significantly increased the relative abundances of health-promoting microbes (including L. frumenti, Lactobacillus gasseri LA39, Parabacteroides distasonis, and Kazachstania telluris) and decreased the relative abundances of opportunistic pathogens (including Desulfovibrio desulfuricans and Candida humilis). Functional alteration of the intestinal bacterial community by L. frumenti administration was characterized by the significantly increased fatty acids and protein metabolism and decreased diseases-associated metabolic pathways. These findings suggest that L. frumenti facilitates intestinal epithelial barrier function maintenance in early-weaned piglets and may be a promising antibiotic alternative used for intestinal epithelial barrier function damage prevention in mammals.

It has been shown that benidipine, a long-lasting calcium (Ca) channel blocker, may exert its protective effect against vascular disorders by increasing nitric oxide (NO) production. The purpose of the present study was to investigate whether orally administered benidipine might influence the membrane function in patients with essential hypertension. We measured the membrane fluidity of erythrocytes by using an electron paramagnetic resonance (EPR) and spin-labeling method. In the preliminary study using erythrocytes obtained from healthy volunteers, benidipine decreased the order parameter (S) for 5-nitroxide stearate (5-NS) and the peak height ratio (ho/h-1) for 16-NS in the EPR spectra in vitro. The finding indicated that benidipine increased the membrane fluidity and improved the microviscosity of erythrocytes. In addition, it was demonstrated that the effect of benidipine on membrane fluidity of erythrocytes was significantly potentiated by the NO-substrate, L-arginine. In the separate series of the study, we observed that orally administered benidipine for 4 weeks significantly increased the membrane fluidity of erythrocytes with a concomitant increase in plasma NO metabolite levels in hypertensive subjects. The results of the present study demonstrated that benidipine might increase the membrane fluidity and improve the microviscosity of erythrocytes both in vitro and in vivo, to some extent, by the NO-dependent mechanism. Furthermore, it is strongly suggested that orally administered benidipine might have a beneficial effect on the rheologic behavior of erythrocytes and the improvement of the microcirculation in hypertensive subjects.

Symptoms of dry eye are commonly reported in contact lens wearers and are a frequent cause of non-tolerance. The purpose of the present study is to evaluate the effects of oral treatment with particular omega-6 fatty acids in the form of evening primrose oil (EPO) on subjective symptoms, ocular surface signs and tear film characteristic in patients with contact lens associated dry eye. The study design was randomised, double-masked and placebo controlled. 76 female soft contact lens wearers were treated for 6 months with either EPO or placebo (olive oil). Subjects underwent three examinations (baseline, 3 and 6 months). At each examination subjects were given a questionnaire relating to lens comfort and dry eye symptoms and underwent a series of tests of tear film characteristics (tear meniscus height, break-up time), meibomian gland function (lipid layer thickness and quality) and ocular surface parameters (hyperaemia and staining). The EPO group showed a significant improvement in the specific symptom of 'dryness' at 3 and 6 months (p<0.01) and also a significant improvement in overall lens comfort at 6 months (p<0.01). Tear meniscus height was increased in the EPO group at 6 months relative to baseline (p<0.01), although all other objective signs were unchanged. This study provides evidence for a beneficial effect of particular orally administered omega-6 fatty acids in alleviating dry eye symptoms and improving overall lens comfort in patients suffering from contact lens associated dry eye.

Gaucher disease (GD) is a lysosomal storage disease characterized by a deficiency of glucocerebrosidase. Although enzyme-replacement and substrate-reduction therapies are available, their efficacies in treating the neurological manifestations of GD are negligible. Pharmacological chaperone therapy is hypothesized to offer a new strategy for treating the neurological manifestations of this disease. Specifically, ambroxol, a commonly used expectorant, has been proposed as a candidate pharmacological chaperone. The purpose of this study was to evaluate the safety, tolerability, and neurological efficacy of ambroxol in patients with neuronopathic GD. This open-label pilot study included five patients who received high-dose oral ambroxol in combination with enzyme replacement therapy. Safety was assessed by adverse event query, physical examination, electrocardiography, laboratory studies, and drug concentration. Biochemical efficacy was assessed through evidence of glucocerebrosidase activity in the lymphocytes and glucosylsphingosine levels in the cerebrospinal fluid. Neurological efficacy was evaluated using the Unified Myoclonus Rating Scale, Gross Motor Function Measure, Functional Independence Measure, seizure frequency, pupillary light reflex, horizontal saccadic latency, and electrophysiologic studies. High-dose oral ambroxol had good safety and tolerability, significantly increased lymphocyte glucocerebrosidase activity, permeated the blood-brain barrier, and decreased glucosylsphingosine levels in the cerebrospinal fluid. Myoclonus, seizures, and pupillary light reflex dysfunction markedly improved in all patients. Relief from myoclonus led to impressive recovery of gross motor function in two patients, allowing them to walk again. Pharmacological chaperone therapy with high-dose oral ambroxol shows promise in treating neuronopathic GD, necessitating further clinical trials.

Mutations in the metallo-protein Cu/Zn-superoxide dismutase (SOD1) cause amyotrophic lateral sclerosis (ALS) in humans and an expression level-dependent phenotype in transgenic rodents. We show that oral treatment with the therapeutic agent diacetyl-bis(4-methylthiosemicarbazonato)copper(II) [Cu(II)(atsm)] increased the concentration of mutant SOD1 (SOD1G37R) in ALS model mice, but paradoxically improved locomotor function and survival of the mice. To determine why the mice with increased levels of mutant SOD1 had an improved phenotype, we analyzed tissues by mass spectrometry. These analyses revealed most SOD1 in the spinal cord tissue of the SOD1G37R mice was Cu deficient. Treating with Cu(II)(atsm) decreased the pool of Cu-deficient SOD1 and increased the pool of fully metallated (holo) SOD1. Tracking isotopically enriched (65)Cu(II)(atsm) confirmed the increase in holo-SOD1 involved transfer of Cu from Cu(II)(atsm) to SOD1, suggesting the improved locomotor function and survival of the Cu(II)(atsm)-treated SOD1G37R mice involved, at least in part, the ability of the compound to improve the Cu content of the mutant SOD1. This was supported by improved survival of SOD1G37R mice that expressed the human gene for the Cu uptake protein CTR1. Improving the metal content of mutant SOD1 in vivo with Cu(II)(atsm) did not decrease levels of misfolded SOD1. These outcomes indicate the metal content of SOD1 may be a greater determinant of the toxicity of the protein in mutant SOD1-associated forms of ALS than the mutations themselves. Improving the metal content of SOD1 therefore represents a valid therapeutic strategy for treating ALS caused by SOD1. Copyright © 2014 the authors 0270-6474/14/348021-11$15.00/0.

Acute Hepatotoxicity of Intravenous Amiodarone: Case Report and Review of the Literature.

PubMed

Chen, Chia-Chi; Wu, Chien-Chih

2016-01-01

Amiodarone is a class III antiarrhythmic drug widely used for the treatment of both supraventricular and ventricular arrhythmias in intensive care unit. Hepatotoxicity of amiodarone is usually mild and delayed onset. Acute hepatotoxicity is a rare side effect and usually correlated to intravenous form use. In this case, acute hepatocellular injury occurred within 24 hours after the administration of intravenous amiodarone. Liver enzyme significantly improved after holding intravenous amiodarone use. Because ventricular arrhythmia persisted and side effects occurred to alternative therapy, low dose of oral amiodarone was resumed and hepatotoxicity did not occur afterward. Acute hepatotoxicity of intravenous amiodarone is possibly related to polysorbate 80, the solubilizer of amiodarone infusion or higher dose. As a result, when intravenous amiodarone is prescribed, closely monitoring liver enzyme is highly suggested. If acute hepatitis takes place secondary to intravenous amiodarone, oral therapy should not be resumed afterward. If there is no alternative treatment, lower dose of oral amiodarone (≤200 mg/d) could be tried and should monitor liver function regularly.

Impact of Absorption and Transport on Intelligent Therapeutics and Nano-scale Delivery of Protein Therapeutic Agents

PubMed Central

Peppas, Nicholas A.; Carr, Daniel A

2009-01-01

The combination of materials design and advances in nanotechnology has led to the development of new therapeutic protein delivery systems. The pulmonary, nasal, buccal and other routes have been investigated as delivery options for protein therapy, but none result in improved patient compliances and patient quality of life as the oral route. For the oral administration of these new systems, an understanding of protein transport is essential because of the dynamic nature of the gastrointestinal tract and the barriers to transport that exist. Models have been developed to describe the transport between the gastrointestinal lumen and the bloodstream, and laboratory techniques like cell culture provide a means to investigate the absorption and transport of many therapeutic agents. Biomaterials, including stimuli-sensitive complexation hydrogels, have been investigated as promising carriers for oral delivery. However, the need to develop models that accurately predict protein blood concentration as a function of the material structure and properties still exists. PMID:20161384

Efficacy of oral vancomycin in recurrent primary sclerosing cholangitis following liver transplantation.

Primary sclerosing cholangitis (PSC) is a liver disease that leads to progressive destruction and stricturing of the biliary tree. Unfortunately, apart from orthotopic liver transplantation (OLT), there are no universally accepted therapies to treat this disease. Even following transplantation, recurrence of PSC is seen in approximately one quarter of patients and leads to high rates of graft failure. Oral vancomycin, through possible immunomodulatory and anti-inflammatory mechanisms, has been shown in small-scale studies to be successful in improving liver function tests in patients with pretransplant PSC. We report the first case of an adult patient diagnosed with recurrent PSC 4 years after OLT who was treated with oral vancomycin leading to complete normalisation of his liver biochemistry. This case adds to the growing literature of a potential therapeutic role for this antibiotic in PSC and highlights interesting questions regarding mechanisms of disease. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Collagen tripeptide (CTP) is a functional food material with several biological effects such as improving dry skin and wound and bone fracture healing. This study focused on the anti-photoaging effects of CTP on a hairless mouse model. To evaluate the effects of CTP on UVB-induced skin wrinkle formation in vivo, the hairless mice were exposed to UVB radiation with oral administration of CTP for 14 weeks. Compared with the untreated UVB control group, mice treated with CTP showed significantly reduced wrinkle formation, skin thickening, and transepidermal water loss (TEWL). Skin hydration and hydroxyproline were increased in the CTP-treated group. Moreover, oral administration of CTP prevented UVB-induced MMP-3 and -13 activities as well as MMP-2 and -9 expressions. Oral administration of CTP increased skin elasticity and decreased abnormal elastic fiber formation. Erythema was also decreased in the CTP-treated group. Taken together, these results strongly suggest that CTP has potential as an anti-photoaging agent.

Oral diseases are very prevalent across the lifespan and impact overall health, yet are largely preventable. The Smiles for Life (SFL) curriculum was created to educate healthcare providers about oral disease and support integration of oral health and primary care. This study examines SFL's influence on clinical practice and education. Surveys were sent to registered users of SFL. Users who self-identified as direct care providers (DCPs), or educators, were included in the analysis. Survey response rate was 18 percent, with 87 percent identifying as DCPs and 13 percent as educators. Across professions, 85 percent of DCPs reported SFL influencing their practice to some degree, with variance among profession type and experience. DCPs most commonly reported that SFL led them to improve how they conduct oral health activities, with 60 percent performing the activity more skillfully following completion of SFL. Fluoride varnish application was the most common practice behavior initiated, and caries risk assessments was the oral health activity affected to the greatest degree. A majority of educators (94 percent) reported that SFL led them to incorporate or enhance oral health in their teaching. SFL helped educators emphasize the importance of oral health, improved their ability to teach content, raised motivation, and reduced barriers to teaching oral health. Data supports that SFL is positively influencing oral health practice across professions, especially in areas of caries risk assessment and fluoride varnish application. SFL improves the frequency and quality with which DCPs and educators participate in oral health activities, and facilitates oral health inclusion in primary care. © 2017 American Association of Public Health Dentistry.

While the US health care system has the capability to provide amazing treatment of a wide array of conditions, this care is not uniformly available to all population groups. Oral health care is one of the dimensions of the US health care delivery system in which striking disparities exist. More than half of the population does not visit a dentist each year. Improving access to oral health care is a critical and necessary first step to improving oral health outcomes and reducing disparities. Fluoride has contributed profoundly to the improved dental health of populations worldwide and is needed regularly throughout the life course to protect teeth against dental caries. To ensure additional gains in oral health, fluoride toothpaste should be used routinely at all ages. Evidence-based guidelines for annual dental visits and brushing teeth with fluoride toothpaste form the basis of this implementation science project that is intended to bridge the care gap for underserved Asian American populations by improving access to quality oral health care and enhancing effective oral health promotion strategies. The ultimate goal of this study is to provide information for the design and implementation of a randomized controlled trial of a participatory, multi-level, partnered (i.e., with community stakeholders) intervention to improve the oral and general health of low-income Chinese American adults. This study will evaluate the feasibility and acceptability of implementing a partnered intervention using remote data entry into an electronic health record (EHR) to improve access to oral health care and promote oral health. The research staff will survey a sample of Chinese American patients (planned n  = 90) screened at three outreach centers about their satisfaction with the partnered intervention. Providers (dentists and community health workers), research staff, administrators, site directors, and community advisory board members will participate in structured interviews about the partnered intervention. The remote EHR evaluation will include group adaptation sessions and workflow analyses via multiple recorded sessions with research staff, administrators, outreach site directors, and providers. The study will also model knowledge held by non-patient participants to evaluate and enhance the partnered intervention for use in future implementations.

A detailed characterization of oral antigen-presenting cells is critical to improve second-generation sublingual allergy vaccines. To characterize oral dendritic cells (DCs) within lingual and buccal tissues from BALB/c mice with respect to their surface phenotype, distribution, and capacity to polarize CD4(+) T-cell responses. In situ analysis of oral DCs was performed by immunohistology. Purified DCs were tested in vitro for their capacity to capture, process, and present the ovalbumin antigen to naive CD4(+) T cells. In vivo priming of ovalbumin-specific T cells adoptively transferred to BALB/c mice was analyzed by cytofluorometry in cervical lymph nodes after sublingual administration of mucoadhesive ovalbumin. Three subsets of oral DCs with a distinct tissue distribution were identified: (1) a minor subset of CD207(+) Langerhans cells located in the mucosa itself, (2) a major subpopulation of CD11b(+)CD11c(-) and CD11b(+)CD11c(+) myeloid DCs at the mucosal/submucosal interface, and (3) B220(+)120G8(+) plasmacytoid DCs found in submucosal tissues. Purified myeloid and plasmacytoid oral DCs capture and process the antigen efficiently and are programmed to elicit IFN-gamma and/or IL-10 production together with a suppressive function in naive CD4(+) T cells. Targeting the ovalbumin antigen to oral DCs in vivo by using mucoadhesive particles establishes tolerance in the absence of cell depletion through the stimulation of IFN-gamma and IL-10-producing CD4(+) regulatory T cells in cervical lymph nodes. The oral immune system is composed of various subsets of tolerogenic DCs organized in a compartmentalized manner and programmed to induce T(H)1/regulatory T-cell responses.

To better understand the role of the professional oral health care for elderly in improving geriatric oral health, the effects of short-term professional oral health care (once per week for 1 month) on oral microbiological parameters were assessed. Parallel, open-labelled, randomize-controlled trial was undertaken in a nursing home for elderly in Shizuoka, Japan. Thirty-four dentate elderly over 74 years were randomly assigned from ID number to the intervention (17/34) and control (17/34) groups. The outcomes were changes in oral microbiological parameters (number of bacteria in unstimulated saliva; whole bacteria, Streptococcus, Fusobacterium and Prevotella: opportunistic pathogens detection: and index of oral hygiene evaluation [Dental Plaque Index, DPI]) within the intervention period. Each parameter was evaluated at before and after intervention period. Four elderly were lost from mortality (1), bone fracture (1), refused to participate (1) and multi-antibiotics usage (1). Finally, 30 elderly were analysed (14/intervention and 16/control). At baseline, no difference was found between the control and intervention groups. After the intervention period, the percentage of Streptococcus species increased significantly in the intervention group (Intervention, 86% [12/14]; Control, 50% [8/16]: Fisher's, right-tailed, P < 0.05). Moreover, DPI significantly improved in the intervention group (Intervention, 57% [8/14]; Control, 13% [2/16]: Fisher's, two-tailed, P < 0.05). The improvement in DPI extended for 3 months after intervention. None of side effects were reported. The short-term professional oral health care can improve oral conditions in the elderly. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The aim of this study was to assess the effect of d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) on the physicochemical characterization and oral bioavailability of a novel l-sulpiride-loaded quaternary microcapsule (QMC). The effect of carriers on drug solubility was investigated. Among the carriers tested, polyvinyl pyrrolidone (PVP), sodium lauryl sulphate (SLS) and TPGS were selected as polymer, surfactant and absorption enhancer, respectively, due to their high drug solubility. Using the solvent evaporation method, numerous QMCs with different ratios of l-sulpiride, PVP, SLS and TPGS were prepared, and their physicochemical properties, solubility and release were evaluated. In addition, the influence of TPGS concentration on the oral bioavailability of various drug doses was evaluated. All QMCs converted the crystalline drug to the amorphous form and remarkably improved the solubility, release and oral bioavailability of the drug. Furthermore, the TPGS concentration in the QMCs hardly affected the crystallinity, particle size and release, but considerably increased the solubility and oral bioavailability of the drug. In particular, as the dose of administered drug was increased, TPGS provided a greater improvement in oral drug bioavailability. Thus, TPGS played an important role in improving the oral bioavailability of l-sulpiride. Moreover, the QMC with a drug/PVP/SLS/TPGS weight ratio of 5:12:1 :20 with approximately 3.3-fold improved oral bioavailability would be recommended as a commercial pharmaceutical product for oral administration of l-sulpiride.

The goal of this study was the evaluation of the periodontal health by means of CPI score in inhabitants of big and small cities in the age range from 65 to 74 and making comparison with previous Polish and European studies from XXI century. Also an average number of natural teeth, the edentulous persons percentage, the percentage of people with oral function maintenance and prevalence of oral mucosal diseases were evaluated. There were also attempts to evaluate essential behaviours related to the oral health and the percentage of people that are treated with use of non-reimbursed or reimbursed services. Studies were conducted in 5 big cities: Warszawa, Szczecin, Wrocław, Białystok and Toruń, as well as in 4 towns, such as Oława, Police, Łobez and Ełk. From sampling 7400 people aged from 65 to 74 years for the study reported only 807 people. In the mouth evaluated CPI score, number of natural teeth and prevalence of pathological lesions on cavity mucosa. Answers for questions on selected attitudes and health-seeking behaviours related to the oral health and the range of dental treatment were also analysed. Distribution of values of CPI codes in the whole group was as follows: CPI0-1.2%, CPI1-9.4%, CPI2-16.6%, CPI3-21.8%, CPI4-19.7% and the number of people excluded from examinations (1 tooth in the sextant or edentulous 31.3%). The state of the periodontium was worse in big cities and in men. An average number of teeth was 13.7 and was higher in big cities and in men. The percentage of edentulous persons was 28.9% and was higher in towns and in woman. The percentage of people with oral function maintenance was 25.15% and was higher in big cities and in men. The most three common pathologies of the oral cavity were leukoplakia and leukokeratosis that were found in 10.5% of examined people, candidiasis 5.82% and lichen planus 2.2%. The state of the periodontium of Poles at the age from 65 to 74 has not been improved in XXI century, but also does not significantly differ from an average European level. An average number of remaining teeth of Poles at this age has increased, but remains under a European average; also the prevalence of edentulism has decreased, but still remains one of the highest in Europe. The percentage of people with oral function maintenance is very low, thus needs for prosthetic treatment and rehabilitation of masticatory ability remain high. Precancerous lesions in the oral cavity are quite common in this age group. Health-seeking behaviours related to the oral health of older Poles are inadequate and result from a low level of knowledge on dental prophylaxis.

γ-Aminobutyric acid (GABA) is a kind of amino acid contained in green tea leaves and other foods. Several reports have shown that GABA might affect brain protein synthesis, improve many brain functions such as memory and study capability, lower the blood pressure of spontaneously hypertensive rats, and may also have a relaxation effect in humans. However, the evidence for its mood-improving function is still not sufficient. In this study, we investigated how the oral intake of GABA influences human adults psychologically and physiologically under a condition of mental stress. Sixty-three adults (28 males, 35 females) participated in a randomized, single blind, placebo-controlled, crossover-designed study over two experiment days. Capsules containing 100 mg of GABA or dextrin as a placebo were used as test samples. The results showed that EEG activities including alpha band and beta band brain waves decreased depending on the mental stress task loads, and the condition of 30 min after GABA intake diminished this decrease compared with the placebo condition. That is to say, GABA might have alleviated the stress induced by the mental tasks. This effect also corresponded with the results of the POMS scores.

To evaluate changes in the general and oral health-related quality of life (using the European Quality of Life indicator and the Oral Health Impact Profile-49 [OHIP-49], respectively) of patients treated with conventionally or immediately loaded implants. This clinical trial consisted of a clinical oral examination and a questionnaire-based interview carried out before and after both surgery and definitive prosthetic rehabilitation in a consecutive sample of patients requiring dental implants. According to the clinical diagnosis and patient preference, patients were assigned to the immediate loading group (IL group; n = 29) or the conventional loading group (CL group; n = 75). The change summary scores and effect sizes were calculated in the intermediate stage and at the final follow-up, taking baseline scores as reference. The oral health-related quality of life and oral satisfaction after implant therapy were significantly better than at baseline, with an even greater benefit when the implants were loaded immediately than when prosthetic rehabilitation was delayed. However, there were no significant differences in between-group comparisons in the ratings of general health status. The effect size for the OHIP-49 exceeded the threshold value of 0.8 for the domains functional limitation, pain/discomfort, and psychological discomfort in both groups and also for physical disability and psychological disability in the IL group. A gradual improvement in oral well-being scores, but not in those of general well-being, were observed for both groups from the intermediate stage to the final evaluation. This benefit was markedly greater for the IL group.

The purpose was to explore the relationship between the level of functioning (listening/talking/reading/daily self-care/care at home/social skills) of three to 21-year-old patients with autism spectrum disorders (ASDs) and their oral health and oral health-related behavior (brushing, flossing, dental visits). Survey data were collected from 85 parents of ASD patients. Patients' level of functioning was determined with a short version of the Survey Interview Form of the Vineland Adaptive Behavior Scales (2nd edition). The patients ranged from very low to high levels of functioning. Oral health correlated with the ability to: listen (r=.53; P<.001); talk (r=.40; P<.001); read (r=.30; P<.01); engage in daily self-care (r=.36; P<.001); engage in care at home (r=.44; P<.001); and demonstrate social skills (r=.36; P<.001). The parents' comfort levels concerning brushing and flossing their children's teeth and taking their children to the dentist varied considerably and correlated with children's level of functioning. Frequency of tooth-brushing correlated with listening skills (r=31; P<.01); the frequency of flossing correlated with the ability to talk (r=.31; P<.01). Understanding the relationships between level of functioning of children with ASDs and their oral health and oral health-related behavior could increase dentists' ability to provide the best possible care for these patients.

Many women experience sexual dysfunction where there are orgasm disorders and sexual difficulties. Ashwagandha (Withania somnifera) is a herb known to improve the body's physical and psychological condition. The purpose of the study was to determine the efficacy and safety of a high-concentration ashwagandha root extract (HCARE) supplementation for improving sexual function in healthy females. In this pilot study, 50 study subjects were randomized to either (i) HCARE-treated group or (ii) placebo- (starch-) treated group. The subjects consumed either HCARE or placebo capsules of 300mg twice daily for 8 weeks. Sexual function was assessed using two psychometric scales, the Female Sexual Function Index (FSFI) Questionnaire and the Female Sexual Distress Scale (FSDS), and by the number of total and successful sexual encounters. The analysis indicates that treatment with HCARE leads to significantly higher improvement, relative to placebo, in the FSFI Total score (p < 0.001), FSFI domain score for "arousal" (p < 0.001), "lubrication" (p < 0.001), "orgasm" (p = 0.004), and "satisfaction" (p < 0.001), and also FSDS score (p < 0.001) and the number of successful sexual encounters (p < 0.001) at the end of the treatment. This study demonstrated that oral administration of HCARE may improve sexual function in healthy women. The present study is registered in the Clinical Trial Registry, Government of India, with a number CTRI/2015/07/006045.

Developing Oral Case Presentation Skills: Peer and Self-Evaluations as Instructional Tools.

Oral case presentation is an essential skill in clinical practice that is decidedly varied and understudied in teaching curricula. We developed a curriculum to improve oral case presentation skills in medical students. As part of an internal medicine clerkship, students receive instruction in the elements of a good oral case presentation and then present a real-world case in front of a video camera. Each student self-evaluates his/her presentation and receives evaluations from his/her peers. We expect peer and self-evaluation to be meaningful tools for developing skills in oral presentation. We hope to not only improve the quality of oral case presentations by students but also to reduce the time burden on faculty.

Many low- and middle-income countries do not yet have policies to implement effective oral health programs. A reason is lack of human and financial resources. Gaps between resource needs and available health funding are widening. By building capacity, countries aim to improve oral health through actions by oral health care personnel and oral health care organizations and their communities. Capacity building involves achieving measurable and sustainable results in training, research, and provision of care. Actions include advancement of knowledge, attitudes and skills, expansion of support, and development of cohesiveness and partnerships. The aim of this critical review is to review existing knowledge and identify gaps and variations between and within different income levels in relation to the capacity building and financing oral health in the African and Middle East region (AMER). A second aim is to formulate research priorities and outline a research agenda for capacity building and financing to improve oral health and reduce oral health inequalities in the AMER. The article focuses on capacity building for oral health and oral health financing in the AMER of the IADR. In many communities in the AMER, there are clear and widening gaps between the dental needs and the existing capacity to meet these needs in terms of financial and human resources. Concerted efforts are required to improve access to oral health care through appropriate financing mechanisms, innovative health insurance schemes, and donor support and move toward universal oral health care coverage to reduce social inequality in the region. It is necessary to build capacity and incentivize the workforce to render evidence-based services as well as accessing funds to conduct research on equity and social determinants of oral health while promoting community engagement and a multidisciplinary approach. © International & American Associations for Dental Research 2015.

Prosthodontic rehabilitation helps to improve the oral health-related quality of life (OHRQOL). The Liverpool Oral Rehabilitation Questionnaire (LORQ) and Oral Health Impact Profile (OHIP) are specific tools that measure OHRQOL. The primary objective of this study was to assess the impact of oral rehabilitation on patients' OHRQOL following treatment for cancer of oral cavity using LORQ version 3 (LORQv3) and OHIP-14 questionnaire. Secondary objectives were to identify issues specific to oral rehabilitation, patients compliance to prosthetic rehabilitation, the effect of radiation treatment on prosthetic rehabilitation, to achieve meaningful differences over a time before & after prosthetic intervention, to carryout and document specific patient-deprived problem. Seventy-five oral cancer patients were studied. Patients were asked to rate their experience of dental problems before fabrication of prosthesis and after 1 year using LORQv3 and OHIP-14. The responses were compared on Likert scale. Patients reported with extreme problems before rehabilitation. After 1 year of prosthetic rehabilitation, there was improvement noticed in all the domain of LORQv3 and OHIP-14. Complete compliance to the use of prosthetic appliances for 1 year study period was noted. In response to the question no. 40 (LORQv3), only 15 patients who belonged to the obturator group, brought to notice the problems which were not addressed in the LORQv3 questionnaire. The study showed that the oral cancer patients coped well and adapted to near normal oral status after prosthetic rehabilitation. This contributed to the improved overall health-related quality of life.

Oral epithelia protect against constant challenges by bacteria, viruses, toxins and injury while also contributing to the formation of ectodermal appendages such as teeth, salivary glands and lingual papillae. Despite increasing evidence that differentiation pathway genes are frequently mutated in oral cancers, comparatively little is known about the mechanisms that regulate normal oral epithelial development. Here, we characterize oral epithelial stratification and describe multiple distinct functions for the mitotic spindle orientation gene LGN (Gpsm2) in promoting differentiation and tissue patterning in the mouse oral cavity. Similar to its function in epidermis, apically localized LGN directs perpendicular divisions that promote stratification of the palatal, buccogingival and ventral tongue epithelia. Surprisingly, however, in dorsal tongue LGN is predominantly localized basally, circumferentially or bilaterally and promotes planar divisions. Loss of LGN disrupts the organization and morphogenesis of filiform papillae but appears to be dispensable for embryonic hair follicle development. Thus, LGN has crucial tissue-specific functions in patterning surface ectoderm and its appendages by controlling division orientation. PMID:27317810

The actions of tyrosine phosphorylation and dephosphorylation are controlled by tyrosine kinases and phosphatases. Although substantial previous data have revealed the role of several protein tyrosine phosphatases (PTPs) in various cancers, the function of protein tyrosine phosphatase receptor R (PTPRR) and protein tyrosine phosphatase, receptor-type, Z polypeptide 1 (PTPRZ1) proteins in oral cavity squamous cell carcinoma (SCC) has not been studied to date. The PTPRR and PTPRZ1 immunoreactivity in 67 formalin-fixed and paraffin-embedded oral cancer tissues at different stages were analyzed with the technique of immunohistochemistry (IHC). The presence of PTPRR in cancerous tissue was confirmed by Western blotting. The occurrence of PTPRR and PTPRZ1 proteins in the cancer specimens was more frequent in lower grade tumors. In addition, the association between the immunoreactivity of both examined proteins and improved patients survival was detected. Moreover, the PTPRR expression was found to be related to the absence of synchronous lymph node involvement. The above results indicate that the PTPRR and PTPRZ1 protein expression should be monitored in oral cancer for patients' prognostic stratification. © 2015 Wiley Periodicals, Inc.

Trismus can be a challenging consequence of ballistic trauma to the face, and has rarely been described in the setting of face transplantation. Almost half of all current face transplant recipients in the world received transplantation to restore form and function after a ballistic injury. Here we report our experience and challenges with long standing trismus after face transplantation. We reviewed the medical records of our face transplant recipients whose indication was ballistic injury. We focused our review on trismus and assessed the pre-, peri- and postoperative planning, surgery and functional outcomes. Two patients received partial face transplantation, including the midface for ballistic trauma. Both patients suffered from impaired mouth opening, speech intelligibility, and oral competence. Severe scarring of the temporomandibular joint (TMJ) required intraoperative release in both patients, and additional total condylectomy on the left side 6 months posttransplant for 1 patient. Posttransplant, both patients achieved an improvement in mouth opening; however, there was persistent trismus. One year after transplantation, range of motion of the jaw had improved for both patients. Independent oral food intake was possible 1 year after surgery, although spillage of liquids and mixed consistency solids persisted. Speech intelligibility testing showed impairments in the immediate postoperative period, with improvement to over 85% for both patients at 1 year posttransplant. Ballistic trauma to the face and subsequent reconstructive measures can cause significant scarring and covert injuries to structures such as the TMJ, resulting in long standing trismus. Meticulous individual planning prior to interventions such as face transplantation must take these into account. We encourage intraoperative evaluation of these structures as well as peri- and postoperative treatment when necessary. Due to the nature of the primary injury, functional outcomes after face transplantation in these patients may differ substantially from those of other indications.

This experimental study determined if a "report card-like" oral health action plan was effective in improving oral health behaviors in a sample of 69 patients, ages 1 to 6 years. Participants were divided randomly into control and intervention groups. Data collected included dmft, plaque score, Streptococcus mutans levels and oral health behaviors. Participants in the intervention group received an oral health action plan that included: 1. child's current caries-risk status; 2. identification issues of concern; and 3. one "goal" to improve on for the next visit. All participants returned after two months for follow-up examination and data collection.

To evaluate the impact of Oral Potentially Malignant Disorders (OPMD) on daily life activities. Patients diagnosed with Oral Leukoplakia, Oral submucous fibrosis and Oral Lichen Planus attending the Oral Medicine clinic of Panineeya Institute of Dental Sciences & Research Centre, Hyderabad, India were invited to participate. Eighteen interviews and three focus groups were conducted in a non-clinical setting. Voice recordings were transcribed and translated from Telugu to English. Data coding was performed using the NVivo software. Sample size for this qualitative study comprised 32 patients. Four main themes emerged: (1) difficulties with diagnosis and knowledge about the condition, (2) physical impairment and functional limitations, (3) psychological and social wellbeing and (4) effects of treatment on daily life. In a majority of the patients, most of the interview time was spent discussing physical impairment and functional limitations. Patients also reported their mouth condition having a debilitating effect on their psychological well-being and social interactions. 'Physical impairment and functional limitations' was the most important theme for many of the patients. However, the impacts of OPMD also extended beyond physical impairment and functional limitations to aspects of daily living, notably psychological and social wellbeing.

Eating disorders, including anorexia and bulimia nervosa, are potentially life-threatening syndromes characterized by severe disturbances in eating behavior. An effective treatment strategy for these conditions remains to be established, as patients with eating disorders tend to suffer from multiple relapses. Because ghrelin was originally discovered in the stomach mucosa, it has been widely studied over the past decade in an effort to uncover its potential roles; these studies have shed light on the mechanism by which ghrelin regulates food intake. Thus, studying ghrelin in the context of eating disorders could improve our understanding of the pathogenesis of eating disorders, possibly resulting in a promising new pharmacological treatment strategy for these patients. In addition, early detection and treatment of eating disorders are critical for ensuring recovery of young patients. Oral symptoms, including mucosal, dental, and saliva abnormalities, are typically observed in the early stages of eating disorders. Although oral care is not directly related to the treatment of eating disorders, knowledge of the oral manifestations of eating disorder patients may aid in early detection, resulting in earlier treatment; thus, oral care might contribute to overall patient management and prognosis. Moreover, ghrelin has also been found in saliva, which may be responsible for oral hygiene and digestion-related functions. This review discusses the pharmacological potential of ghrelin in regulating food-intake and the role of saliva and oral care in young patients with eating disorders. PMID:23016127

Alzheimer's disease is an age-dependent progressive neurodegenerative disorder that results in impairments of memory and cognitive function. It is hypothesized that oligonol has ameliorative effects on memory impairment and reduced cognitive functions in mice with Alzheimer's disease induced by amyloid β(25-35) (Aβ(25-35)) injection. The protective effect of an oligonol against Aβ(25-35)-induced memory impairment was investigated in an in vivo Alzheimer's mouse model. The aggregation of Aβ25-35 was induced by incubation at 37°C for 3 days before injection into mice brains (5 nmol/mouse), and then oligonol was orally administered at 100 and 200 mg/kg of body weight for 2 weeks. Memory and cognition were observed in T-maze, object recognition, and Morris water maze tests. The group injected with Aβ(25-35) showed impairments in both recognition and memory. However, novel object recognition and new route awareness abilities were dose dependently improved by the oral administration of oligonol. In addition, the results of the Morris water maze test indicated that oligonol exerted protective activity against cognitive impairment induced by Aβ(25-35). Furthermore, nitric oxide formation and lipid peroxidation were significantly elevated by Aβ(25-35), whereas oligonol treatment significantly decreased nitric oxide formation and lipid peroxidation in the brain, liver, and kidneys. The present results suggest that oligonol improves Aβ(25-35)-induced memory deficit and cognition impairment. Copyright © 2014 Elsevier Inc. All rights reserved.

The aims of this study were to clarify the effectiveness of L-arginine (1) for reducing the severity of anatomical changes in the eye and improving visual function in the acute stage of a rodent model of nonarteritic ischemic optic neuropathy (rNAION) and (2) in preventing those changes in anatomy and visual function. For the first aim, L-arginine was intravenously injected into rats 3 h after rNAION induction; for the second aim, rNAION was induced after the oral administration of L-arginine for 7 days. The inner retinal thickness was determined over time by optical coherence tomography, and the amplitude of the scotopic threshold response (STR) and the number of surviving retinal ganglion cells (RGCs) were measured. These data were compared with the baseline data from the control group. Both intravenous infusion of L-arginine after rNAION induction and oral pretreatment with L-arginine significantly decreased optic disc edema in the acute stage and thinning of the inner retina, reduced the decrease in STR amplitude, and reduced the decrease in the number of RGCs during rNAION. Based on these results, we conclude that L-arginine treatment is effective for reducing anatomical changes in the eye and improving visual function in the acute stage of rNAION and that pretreatment with L-arginine is an effective therapy to reduce the severity of the condition during recurrence in the other eye.

Sodium Phenylbutyrate Enhances Astrocytic Neurotrophin Synthesis via Protein Kinase C (PKC)-mediated Activation of cAMP-response Element-binding Protein (CREB)

Neurotrophins, such as brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3), are believed to be genuine molecular mediators of neuronal growth and homeostatic synapse activity. However, levels of these neurotrophic factors decrease in different brain regions of patients with Alzheimer disease (AD). Induction of astrocytic neurotrophin synthesis is a poorly understood phenomenon but represents a plausible therapeutic target because neuronal neurotrophin production is aberrant in AD and other neurodegenerative diseases. Here, we delineate that sodium phenylbutyrate (NaPB), a Food and Drug Administration-approved oral medication for hyperammonemia, induces astrocytic BDNF and NT-3 expression via the protein kinase C (PKC)-cAMP-response element-binding protein (CREB) pathway. NaPB treatment increased the direct association between PKC and CREB followed by phosphorylation of CREB (Ser133) and induction of DNA binding and transcriptional activation of CREB. Up-regulation of markers for synaptic function and plasticity in cultured hippocampal neurons by NaPB-treated astroglial supernatants and its abrogation by anti-TrkB blocking antibody suggest that NaPB-induced astroglial neurotrophins are functionally active. Moreover, oral administration of NaPB increased the levels of BDNF and NT-3 in the CNS and improved spatial learning and memory in a mouse model of AD. Our results highlight a novel neurotrophic property of NaPB that may be used to augment neurotrophins in the CNS and improve synaptic function in disease states such as AD. PMID:23404502

People with serious mental illness not only experience an erosion of functioning in day-to-day life over a protracted period of time, but evidence also suggests that they have a greater risk of experiencing oral disease and greater oral treatment needs than the general population. Poor oral hygiene has been linked to coronary heart disease, diabetes, and respiratory disease and impacts on quality of life, affecting everyday functioning such as eating, comfort, appearance, social acceptance, and self esteem. Oral health, however, is often not seen as a priority in people suffering with serious mental illness. To review the effects of oral health education (advice and training) with or without monitoring for people with serious mental illness. We searched the Cochrane Schizophrenia Group's Trials Register (5 November 2015), which is based on regular searches of MEDLINE, EMBASE, CINAHL, BIOSIS, AMED, PubMed, PsycINFO, and clinical trials registries. There are no language, date, document type, or publication status limitations for inclusion of records in the register. All randomised clinical trials focusing on oral health education (advice and training) with or without monitoring for people with serious mental illness. We extracted data independently. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated the mean difference (MD) between groups and its 95% CI. We employed a fixed-effect model for analyses. We assessed risk of bias for included studies and created 'Summary of findings' tables using GRADE. We included three randomised controlled trials (RCTs) involving 1358 participants. None of the studies provided useable data for the key outcomes of not having seen a dentist in the past year, not brushing teeth twice a day, chronic pain, clinically important adverse events, and service use. Data for leaving the study early and change in plaque index scores were provided. Oral health education compared with standard careWhen 'oral health education' was compared with 'standard care', there was no clear difference between the groups for numbers leaving the study early (1 RCT, n = 50, RR 1.67, 95% CI 0.45 to 6.24, moderate-quality evidence), while for dental state: no clinically important change in plaque index, an effect was found. Although this was statistically significant and favoured the intervention group, it is unclear if it was clinically important (1 RCT, n = 40, MD - 0.50 95% CI - 0.62 to - 0.38, very low quality evidence).These limited data may have implications regarding improvement in oral hygiene. Motivational interview + oral health education compared with oral health educationSimilarly, when 'motivational interview + oral health education' was compared with 'oral health education', there was no clear difference for the outcome of leaving the study early (1 RCT, n = 60 RR 3.00, 95% CI 0.33 to 27.23, moderate-quality evidence), while for dental state: no clinically important change in plaque index, an effect favouring the intervention group was found (1 RCT, n = 56, MD - 0.60 95% CI - 1.02 to - 0.18 very low-quality evidence). These limited, clinically opaque data may or may not have implications regarding improvement in oral hygiene. Monitoring compared with no monitoringFor this comparison, only data for leaving the study early were available. We found a difference in numbers leaving early, favouring the 'no monitoring' group (1 RCT, n = 1682, RR 1.07, 95% CI 1.00 to 1.14, moderate-quality evidence). However, these data are problematic. The control denominator is implied and not clear, and follow-up did not depend only on individual participants, but also on professional caregivers and organisations - the latter changing frequently resulting in poor follow-up, but not a good reflection of the acceptability of the monitoring to patients. For this comparison, no data were available for 'no clinically important change in plaque index'. We found no evidence from trials that oral health advice helps people with serious mental illness in terms of clinically meaningful outcomes. It makes sense to follow guidelines and recommendations such as those put forward by the British Society for Disability and Oral Health working group until better evidence is generated. Pioneering trialists have shown that evaluative studies relevant to oral health advice for people with serious mental illness are possible.

Ligand grafted nanoparticles have been shown to enhance drug transport across epithelium barrier and are expected to improve drug delivery. However, grafting of these ligands to the surface of pure nanodrug, i.e., nanocrystals (NCs), is a critical challenge due to the shedding of ligands along with the stabilizer upon high dilution or dissolving of the drug. Herein, a non-sheddable nanocage-like stabilizer was designed by covalent cross-linking of poly(acrylic acid)-b-poly(methyl acrylate) on drug nanocrystal surface, and a ligand, wheat germ agglutinin (WGA), was successfully anchored to the surface of itraconazole (ITZ) NCs by covalent conjugation to the nanocage (WGA-cage-NCs). The cellular study showed that large amount of WGA-cage-NCs were adhered to Caco-2 cell membrane, and invaded into cells, resulting in a higher drug uptake than that of ordinary NCs (ONCs). After oral administration to rats, WGA-cage-NC were largely accumulated on the apical side of epithelium cells, facilitating drug diffusing across epithelium barrier. Interestingly, WGA-cage-NCs were capable of invading rat intestinal villi and reaching to lamina propria by transcytosis across goblet cells, which behaved like a foodborne pathogen, Listeria monocytogenes. The WGA-cage-NCs showed an improved oral bioavailability, which was 17.5- and 2.41-folds higher than that of coarse crystals and ONCs, respectively. To our best knowledge, this may represent the first report that a functional ligand was successfully anchored to the surface of pure nanodrug by using a cage-like stabilizer, showing unique biological functions in gastrointestinal tract and having an important significance in oral drug delivery.

The co-primary objectives of this study were to determine the human pharmacokinetics (PK) of oral NR and the effect of NR on whole blood nicotinamide adenine dinucleotide (NAD+) levels. Though mitochondrial dysfunction plays a critical role in the development and progression of heart failure, no mitochondria-targeted therapies have been translated into clinical practice. Recent murine studies have reported associations between imbalances in the NADH/NAD+ ratio with mitochondrial dysfunction in multiple tissues, including myocardium. Moreover, an NAD+ precursor, nicotinamide mononucleotide, improved cardiac function, while another NAD+ precursor, nicotinamide riboside (NR), improved mitochondrial function in muscle, liver and brown adipose. Thus, PK studies of NR in humans is critical for future clinical trials. In this non-randomized, open-label PK study of 8 healthy volunteers, 250 mg NR was orally administered on Days 1 and 2, then uptitrated to peak dose of 1000 mg twice daily on Days 7 and 8. On the morning of Day 9, subjects completed a 24-hour PK study after receiving 1000 mg NR at t = 0. Whole-blood levels of NR, clinical blood chemistry, and NAD+ levels were analyzed. Oral NR was well tolerated with no adverse events. Significant increases comparing baseline to mean concentrations at steady state (Cave,ss) were observed for both NR (p = 0.03) and NAD+ (p = 0.001); the latter increased by 100%. Absolute changes from baseline to Day 9 in NR and NAD+ levels correlated highly (R2 = 0.72, p = 0.008). Because NR increases circulating NAD+ in humans, NR may have potential as a therapy in patients with mitochondrial dysfunction due to genetic and/or acquired diseases.

Objectives The co-primary objectives of this study were to determine the human pharmacokinetics (PK) of oral NR and the effect of NR on whole blood nicotinamide adenine dinucleotide (NAD+) levels. Background Though mitochondrial dysfunction plays a critical role in the development and progression of heart failure, no mitochondria-targeted therapies have been translated into clinical practice. Recent murine studies have reported associations between imbalances in the NADH/NAD+ ratio with mitochondrial dysfunction in multiple tissues, including myocardium. Moreover, an NAD+ precursor, nicotinamide mononucleotide, improved cardiac function, while another NAD+ precursor, nicotinamide riboside (NR), improved mitochondrial function in muscle, liver and brown adipose. Thus, PK studies of NR in humans is critical for future clinical trials. Methods In this non-randomized, open-label PK study of 8 healthy volunteers, 250 mg NR was orally administered on Days 1 and 2, then uptitrated to peak dose of 1000 mg twice daily on Days 7 and 8. On the morning of Day 9, subjects completed a 24-hour PK study after receiving 1000 mg NR at t = 0. Whole-blood levels of NR, clinical blood chemistry, and NAD+ levels were analyzed. Results Oral NR was well tolerated with no adverse events. Significant increases comparing baseline to mean concentrations at steady state (Cave,ss) were observed for both NR (p = 0.03) and NAD+ (p = 0.001); the latter increased by 100%. Absolute changes from baseline to Day 9 in NR and NAD+ levels correlated highly (R2 = 0.72, p = 0.008). Conclusions Because NR increases circulating NAD+ in humans, NR may have potential as a therapy in patients with mitochondrial dysfunction due to genetic and/or acquired diseases. PMID:29211728

Enteral nutrition (EN) is indicated in patients who, although they may not eat enough food, maintain a sufficient function to receive, digest and absorb nutrients digestive system. Oral Nutritional Supplements (SON) are nutritionally complete or incomplete formulas (depending on whether or not provide all the nutrients needed to serve as the sole source of nutrients), which supplement inadequate oral diet. This study aims to evaluate the organoleptic characteristics of hyperproteic, normoproteic and fiber-enriched oral SON. SON test, carried out at the Department of Endocrinology and Nutrition Consortium Hospital General Universitario de Valencia from October 2012 to February 2013. 137 SON were evaluated in total, of which 47 were hyperproteic, 46 normoproteic and 44 enriched in fiber. Of the SON evaluated in the group of hyperproteic the following 3 SON obtained the best scores: Fresenius Prot Energy Drink® (21,27, vanilla flavor), Avant Standard Nut® (20.3 , strawberry flavor) and Resource® Protein (20.01, chocolate flavor) In the group of normoproteic SON the 3 best rated were: Ensure Plus® (22.3, banana flavor), Ensure Plus® (21.9, peach flavor) and Fresubin Energy Drink® (21, strawberry flavor) In the group of fiber-enriched the 3 SON most appreciated were: 2 Kcal Fresubin Fibre Drink® (23.78, vanilla flavor), Ensure Plus® TwoCal (22.9, banana flavor) and Fortimel Compact® (21.5, strawberry flavor) The study aims to guide clinicians on what SON may be more acceptable to the patient, so that the SON serve their purpose and restore or improve nutritional status, as the SON intervention is safe and cost - effective, since they improve both the functionality and quality of life.

This paper outlines the burden of oral diseases worldwide and describes the influence of major sociobehavioural risk factors in oral health. Despite great improvements in the oral health of populations in several countries, global problems still persist. The burden of oral disease is particularly high for the disadvantaged and poor population groups in both developing and developed countries. Oral diseases such as dental caries, periodontal disease, tooth loss, oral mucosal lesions and oropharyngeal cancers, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related oral disease and orodental trauma are major public health problems worldwide and poor oral health has a profound effect on general health and quality of life. The diversity in oral disease patterns and development trends across countries and regions reflects distinct risk profiles and the establishment of preventive oral health care programmes. The important role of sociobehavioural and environmental factors in oral health and disease has been shown in a large number of socioepidemiological surveys. In addition to poor living conditions, the major risk factors relate to unhealthy lifestyles (i.e. poor diet, nutrition and oral hygiene and use of tobacco and alcohol), and limited availability and accessibility of oral health services. Several oral diseases are linked to noncommunicable chronic diseases primarily because of common risk factors. Moreover, general diseases often have oral manifestations (e.g. diabetes or HIV/AIDS). Worldwide strengthening of public health programmes through the implementation of effective measures for the prevention of oral disease and promotion of oral health is urgently needed. The challenges of improving oral health are particularly great in developing countries. PMID:16211157

There are a number of studies linking social capital to oral health among older adults, although the evidence base mainly relies on cross-sectional study designs. The possibility of reverse causality is seldom discussed, even though oral health problems could potentially lead to lower social participation. Furthermore, few studies clearly distinguish between the effects of different dimensions of social capital on oral health. The objective of the study was to examine the longitudinal associations between individual social capital and oral health among older adults. We analyzed longitudinal data from the 3rd and 5th waves of the English Longitudinal Study of Ageing (ELSA). Structural social capital was operationalized using measures of social participation, and volunteering. Number of close ties and perceived emotional support comprised the functional dimension of social capital. Oral health measures were having no natural teeth (edentate vs. dentate), self-rated oral health and oral health-related quality of life. Time-lag and autoregressive models were used to explore the longitudinal associations between social capital and oral health. We imputed all missing data, using multivariate imputation by chained equations. We found evidence of bi-directional longitudinal associations between self-rated oral health, volunteering and functional social capital. Functional social capital was a strong predictor of change in oral health-related quality of life – the adjusted odds ratio of reporting poor oral health-related quality of life was 1.75 (1.33–2.30) for older adults with low vs. high social support. However in the reverse direction, poor oral health-related quality of life was not associated with changes in social capital. This suggests that oral health may not be a determinant of social capital. In conclusion, social capital may be a determinant of subjective oral health among older adults rather than edentulousness, despite many cross-sectional studies on the latter. PMID:25992569

The aim of this study was to determine whether an oral health education program using a Qscan device based on quantitative light-induced fluorescence (QLF) technology could improve the oral hygiene status and oral health literacy of adolescents. One hundred adolescents aged 14-16 years attending a school in Tashkent city were included in this study. The participants were assigned to the following two groups using permuted block randomization technique: (i) control group (traditional learning) and (ii) experimental group (Qscan device-based learning). The participants included in the experimental group received additional education and training on dental plaque removal using the Qscan device. The accumulated levels of plaque were assessed in all participants, who also completed questionnaires about their oral health status, oral health knowledge, attitude, and behavior during an 8-week period. There were statistically significant improvements in the experimental group compared to the control group in the plaque index (0.46 vs 0.07, p < .05), oral health knowledge (19.4 vs 28.8, p < .05), attitude (16.7 vs 20.2, p < .05), and behavior (19.9 vs 30.5, p < .05). This study has demonstrated that an oral health education program based on the use of QLF technology could be useful for improving the oral hygiene status and oral health literacy of adolescents in Uzbekistan.

To evaluate the efficacy of oral finasteride therapy associated with an oral contraceptive containing drospirenone and ethinyl estradiol in premenopausal women with female pattern hair loss. Outpatient consultation for hair disorders at the Department of Dermatology, University of Bologna. Thirty-seven women with female pattern hair loss were treated with oral finasteride, 2.5 mg/d, while taking an oral contraceptive containing drospirenone and ethinyl estradiol. Treatment efficacy was evaluated using global photography and the hair density score from videodermoscopy. A self-administered questionnaire was used to assess patient evaluation of treatment effectiveness. At 12-month follow-up, 23 of the 37 patients were rated as improved using global photography (12 were slightly improved, 8 were moderately improved, and 3 were greatly improved). No improvement was recorded in 13 patients. One patient experienced worsening of the condition. There was a statistically significant (P = .002) increase in the hair density score in 12 patients. No adverse reactions to the drug were reported. Sixty-two percent of the patients demonstrated some improvement of their hair loss with the use of finasteride, 2.5 mg/d, while taking the oral contraceptive. It is unclear whether the success was due to a higher dosage of finasteride (2.5 mg instead of 1 mg) or to its association with the oral contraceptive containing drospirenone, which has an antiandrogenic effect. Further studies are necessary to understand which patterns of female pattern hair loss respond better to this treatment.

There is a lack of knowledge about how oral contraceptives may affect sexual function. To determine whether there is a causal effect of oral contraceptives on sexuality. We hypothesized that a widely used pill impairs sexuality. A double-blind, randomized, placebo-controlled trial. Enrollment began in February 2012 and was completed in August 2015. Karolinska University Hospital, Stockholm, Sweden. A total of 340 healthy women, aged 18-35 years, were randomized to treatment, and 332 completed the study. A combined oral contraceptive (150 μg levonorgestrel and 30 μg ethinylestradiol) or placebo for 3 months of treatment. The primary outcome was the aggregate score on the Profile of Female Sexual Function (PFSF). Secondary outcomes were the seven domains of the PFSF, the Sexual Activity Log, and the Personal Distress Scale. Overall sexual function was similar in women in the oral contraceptive and placebo groups. The PFSF domains desire (-4.4; 95% confidence interval [CI], -8.49 to -0.38; P = .032), arousal (-5.1; 95% CI, -9.63 to -0.48; P = .030), and pleasure (-5.1; 95% CI, -9.97 to -0.32; P = .036) were significantly reduced in comparison to placebo, whereas orgasm, concern, responsiveness, and self-image were similar between groups. The mean frequency of satisfying sexual episodes and personal distress were also similar between groups. This study shows no negative impact of a levonorgestrel-containing oral contraceptive on overall sexual function, although three of seven sexual function domains were adversely affected.

To survey the status of oral cavity hygiene knowledge, attitude and practice (KAP) of rural acquired immunodeficiency syndrome (AIDS) patients and human immunodeficiency virus (HIV) carriers and take corresponding intervention measures to improve the oral health of these patients. From May to August in 2009, the methods of anonymous face to face structured interview and oral examination at the scene were carried out at the baseline in rural AIDS patients/HIV-carriers. According to the results of the survey, intervention measures were taken. The results of the intervention and the oral hygiene status were compared before and after the intervention. The oral health status of 82 AIDS patients and HIV-carriers were in poor before the intervention, and the knowledge of AIDS-related oral health of 76 AIDS patients and HIV-carriers was promoted after interventions, "scaling can spread AIDS" were 22 cases (27%), and after the intervention 41 patients (54%) think that can spread (χ(2) = 20.066, P < 0.001). The oral diseases of related AIDS were decreased dramatically, 68 patients (83%) had gingivitis before intervention and 47 cases (62%) after the intervention (χ(2) = 8.852, P = 0.003). The personal oral cavity hygiene and related oral KAP of AIDS caused by subjective factors had improved to different extent, "brushing teeth over 3 min at every turn", there were over 36 cases (44%) before intervention and 45 patients after intervention (59%) (χ(2) = 4.017, P = 0.045). The oral hygiene and KAP of AIDS patients and HIV-carriers in rural areas were poor and improved after intervention.

Therapy with zygomatic implants (ZIs) or conventional implants (CIs) has proven to be an effective method to restore oral function for systemically healthy patients. However, it is still a major challenge to fully restore oral function to edentulous adult patients with ectodermal dysplasia (ED). The aim of this study was to determine an effective treatment protocol for restoring oral function using ZIs and CIs to edentulous adult ED patients. Ten edentulous adult ED patients were treated in this study. The treatment protocol involved the following: (1) bone augmentation in the region of the anterior teeth; (2) placement of two ZIs and four CIs in the maxilla, and four CIs in the mandible; (3) fabrication of dental prosthesis; and (4) psychological and oral education. Following treatment of these patients, implant success rates, biological complications, patient satisfaction, and psychological changes were recorded. Although there was evidence of bone graft resorption in the maxilla, bone augmentation of the mandible was successful in all patients. Nine CIs in the maxilla failed and were removed. All ZIs were successful, and the CIs success rates were 77.50% in the maxilla and 100% in the mandible, with a mean of 88.75%. The mean peri-implant bone resorption for the CIs ranged from 1.3 ± 0.4 mm to 1.8 ± 0.6 mm, and four cases exhibited gingival hyperplasia in the maxilla and mandible. One hundred percent of the patients were satisfied with the restoration of their oral function, and >50% of the patients exhibited enhanced self-confidence and self-esteem. This study demonstrates that oral function can be restored in edentulous adult ED patients using a comprehensive and systematic treatment protocol involving psychological and oral education, bone augmentation, implant placement, and denture fabrication. Despite these positive outcomes, bone augmentation remains challenging in the anterior region of the maxilla for edentulous adult ED patients. © 2015 Wiley Periodicals, Inc.

Recent advances in ceramics have greatly improved the functional and esthetic properties of restorative materials. New materials offer an esthetic and functional oral rehabilitation, however their impact on opposing teeth is not welldocumented. Peer-reviewed articles published till December 2014 were identified through Pubmed (Medline and Elsevier). Scientifically, there are several methods of measuring the wear process of natural dentition which enhances the comparison of the complicated results. This paper presents an overview of the newly used prosthetic materials and their implication on antagonist teeth or prostheses, especially emphasizing the behavior of zirconia restorations.

Objectives To determine the effectiveness of the Contra Caries Oral Health Education Program (CCOHEP) for improving low-income, Spanish-speaking parents’ oral health knowledge and behaviors for their young children. Mexican American children in the United States suffer disproportionately high prevalence and severity of early childhood caries, yet few evaluated, theory-based behavioral interventions exist for this population. CCOHEP is a theory-based curriculum consisting of four 2-hour interactive classes designed for and by Spanish speakers and led by designated community health educators (promotoras). Topics included children’s oral hygiene, caries etiology, dental procedures, nutrition, child behavior management and parent skill-building activities. Methods Low-income Spanish-speaking parents/caregivers of children aged 0–5 years were recruited through community services in an agricultural city in California. Survey questions from the Oral Health Basic Research Facts Questionnaire measuring oral health related behaviors and knowledge were verbally administered before, immediately after, and 3 months after attendance at CCOHEP. Five questions measured aspects of parental tooth brushing for their children (frequency, using fluoridated toothpaste, brushing before bed, not drinking or eating after nighttime brushing, adult assistance), three questions measured other oral health behaviors, and 16 questions measured oral health-related knowledge. Analyses of within-person changes between pre- and posttests, and again between post-test and three month follow up consisted of McNemar’s test for binary outcomes and sign tests for ordinal outcomes. Results Overall, 105 caregivers participated in CCOHEP (n= 105 pretest, n=95 posttest, n=79 second posttest). At baseline, all parents self-reported doing at least one aspect of toothbrushing correctly, but only 13% reported performing all five aspects according to professional guidelines. At posttest, 44% of parents reported completing all aspects of tooth brushing according to professional guidelines (p<.001). Statistically significant improvements were seen in 4 aspects of toothbrushing (p≤.008) between pretest and posttest (all but adult assistance). The second posttest showed 3 of these improvements were maintained, while adult assistance and the other reported behaviors improved (p≤.008). Between pretest and posttest, checking child’s teeth monthly and frequency of sweet drinks consumption improved (p≤.008) while frequency of eating sweet foods did not change. Knowledge was high at baseline (mean 12.83 of 16), but 6 knowledge items improved significantly between pretest and posttest. Improvements were maintained at second posttest. Conclusions CCOHEP improved low-income Spanish-speaking parents’ oral hygiene knowledge and self-reported behaviors for their young children, and change was sustained 3 months after the end of the intervention. Future, more rigorous evaluation of the intervention is recommended. PMID:27517458

To evaluate the effectiveness of the submental island pedicled flap (SIPF) for the repair of oral soft defects following oral cancer ablation. Thirty consecutive patients undergoing resection of oral cancer followed by reconstruction with SIPF from February 2010 to March 2013 were reviewed. The effectiveness complications, oral function recovering and oncologic outcomes after reconstructive operation with SIPF were evaluated.SPSS software was used to analyze the data. The dimensions of SIPF ranged from a minimum of 4 cm×6 cm to a maximum of 6 cm×15 cm. Of the 30 flaps, 28 were survival completely, one had superficial necrosis but healed with treatments, and one failed due to complete necrosis, with a survival rate of 96.7% (29/30). Operative time ranged from a minimum of 4.5 hours to a maximum of 7.5 hours, mean 6.8 hours, and hospital stay time was 11-18 days, mean 13 days. Thirteen patients (43.3%) received tracheotomy before SIPF operation. Surgical or postoperative complications included temporary marginal mandibular never palsy in one case, neck hematoma in one case, hydrops in the mandibular region in 7 cases, and neck infectionin in 2 cases. Postoperative functional results showed mouth opening was normal in 23 patients, light limitation of mouth opening in 6 cases and obvious limitation of mouth opening in one case. The speech function was re-obtained satisfactorily in 29 patients, but one case with poor speech function. Most patients showed normal swallowing function, of them 26 patients on a full oral diet, 3 patients on a soft diet and one patient on a liquid diet only. Postoperative follow-up time was for 6-19 months (median 13 months), and 4 patients had local recurrence and 2 patients had cervical lymph node metastases. The SIPF is safe, reliable and simple for the reconstruction of middle-small oral soft defects following resection of early-stage oral cancer.

There have been some reports on the efficacy and tolerability of an oral itraconazole (ITCZ) solution as prophylaxis for fungal infection in patients with hematological malignancies. However, there are some cases where the bitter taste of oral ITCZ solution leads to an interruption of administration because the patient refuses to take this medicine. Therefore, we prospectively investigated the pharmacokinetics and promotion of treatment adherence in patients taking oral ITCZ solution mixed with a beverage. Compared with the responses of patients taking oral ITCZ solution with water, the taste of the agent was improved significantly when mixed with orange juice, although the plasma concentration of the agent did not differ between the two groups. Using this method, we can expect an improvement in treatment adherence and this method can easily be applied in clinical practice. This method is highly useful and should become common knowledge.

Disseminated granuloma annulare (DGA) is a benign and usually asymptomatic skin disease. However, many patients feel aesthetically disfigured and ask for treatment. Until today, no standard therapy is recommended. To evaluate the safety and efficacy of oral vitamin E treatment compared to the natural course of DGA. This single-centre observational cohort study included 38 consecutive patients with histologically confirmed DGA. 21 patients underwent treatment with oral vitamin E, whereas 17 patients preferred a wait-and-see approach. Complete healing (40%) and improvement (30%) were frequently seen under oral vitamin E therapy. However, DGA also spontaneously disappeared in 31% and improved in 25% of untreated control patients. Vitamin E therapy was very well tolerated. Oral vitamin E treatment is a safe and probably effective therapy for DGA. As the natural course of DGA leads to complete healing or significant improvement in many cases, 'primum nil nocere' should be the maxim.

To conduct a systematic review and meta-analysis on the efficacy of oral non-steroidal anti-inflammatory drugs for rotator cuff tendinopathy. Systematic review. A literature search was conducted in 4 databases for randomized controlled trials published until 05/2013, comparing the efficacy of oral anti-inflammatory drugs to any other intervention. Studies characteristics were extracted using a standardized form and the methodological quality was evaluated. Results were summarized qualitatively or quantitatively. The mean methodological score of the 12 included studies was 53.6 ± 8.8%. The majority of studies included acute cases and were underpowered to detect differences in adverse events. Compared to a placebo, oral non-steroidal anti-inflammatory drugs were found to provide short-term pain relief (pooled mean difference: -2.69; 95% confidence interval: -1.96 to -3.41) but not function. Oral anti-inflammatory- drugs and corticosteroids injections have similar short-term efficacy in terms of pain reduction as well as in function (pooled standardized mean difference: 0.09; 95% confidence interval: -0.25 to 0.44). Low to moderate grade evidence exists regarding the efficacy of non-steroidal anti-inflammatory drugs for rotator cuff tendinopathy. Oral anti-inflammatory drugs are effective in reducing short-term pain but not function. In terms of pain and function, oral anti-inflammatory drugs in the short term are as effective as corticosteroid injections.

The aim of this study was to compare the effects of the second- and third-generation oral contraceptives on women's reproductive sexual function. This randomized, double-blind, placebo-controlled clinical trial was conducted on 82 married women of reproductive age in Tehran. Samples were randomized into the groups receiving second- and third-generation oral contraceptive pills. Female Sexual Function Index (FSFI) tool was used before the intervention and 2 and 4 months after the intervention. Data analysis was carried out using analysis of variance (ANOVA) within repeated measures and P < 0.05 were considered significant. There was a statistically significant difference in the positive and negative moods between the experimental and control groups before the intervention in the second and fourth months. The second-generation pills caused a decrease in sexual function in the second month and an increase in sexual function in the fourth month, but the third-generation pills led to an increase in sexual function in the second and fourth months. The increase in sexual function that resulted from using the third-generation pills was significantly higher than that resulted on using the second-generation pills. According to the results of this study, sexual functioning decreased in the second month of using the second-generation pills and sexual performance was significantly more on using the third-generation pills compared to second-generation pills. The most common type of oral contraceptive used in Iran is the second-generation oral contraceptive LD™ (low-dose estrogen), which is freely distributed in health centers. Therefore, it is necessary for women who wish to use these contraceptive methods to be educated and consulted before they start using them. The third-generation contraceptive pills can be recommended to women who wish to use oral contraceptives.

Higher FHL was negatively correlated with worse child caries (r = -0.23), but not subjective oral health. Mean FHL seemed to differ by skip pattern (p = 0.087), indicating it may be a potential FHL proxy.

This study reports on the impact evaluation of a Web-based oral health promotion programme aimed at improving the oral health knowledge, attitudes, practices and self-efficacy of independent-living older adults from Melbourne, Australia. With ethics approval from the University of Melbourne, a convenience sample of volunteers 55 years or older was invited to participate in a study to test a web-based oral health promotion program. Consenting volunteers were asked to undergo a structured interview as part of the pre-intervention data collection. The intervention was based on the ORHIS (Oral Health Information Seminars/Sheets) Model and involved computer interaction with six oral health presentations, with no direct oral health professional input. A one group pre-test-post-test quasi-experimental design was chosen to evaluate the intervention. A series of paired t-tests were used to compare pre-test with post-test results. Forty-seven active, independent-living older adults participated in this evaluation. After the intervention participants responded with higher levels of achievement than before participating in this Web-based oral health program. Participants showed significant improvements in oral health attitudes (4.10 vs. 4.94; p<0.01), knowledge (18.37 vs. 23.83; p<0.0001), and self-efficacy (84.37 vs.89.23; p<0.01), as well as, self-reported oral hygiene practices (i.e., frequency of use of dental floss) (p<0.05). The e-ORHIS approach was successful in improving oral health knowledge, attitudes and self-efficacy. As such, it represents a helpful approach for the design of (oral) health interventions in older adults. Further evaluation with a larger sample is required to test the long-term impact including the economic evaluation of the e-ORHIS approach. Copyright © 2016 Elsevier Ireland Ltd.

To evaluate whether a set of oral health resources designed for workforce training was relevant for students undertaking an entry-level nursing or aged care qualification. Oral health is one of the most neglected aspects of nursing care experienced by older people. Despite efforts to improve aged care worker oral health knowledge and skills, one-off training and rapid staff turnover have hindered the success of workplace programmes. Inadequate oral health content in entry-level nursing and aged care qualifications has perpetuated this. Kirkpatrick's training and evaluation model was used to evaluate the resources developed by a project called Building Better Oral Health Communities. Students used them as prescribed study materials and completed pre- and postintervention questionnaires. Educators were interviewed to obtain their feedback. Quantitative data were analysed using descriptive and inferential statistics. Qualitative data were collated according to relevance to learning, presentation style and interest. Evaluation showed high levels of student and educator satisfaction. Student learning outcomes demonstrated consistently positive attitudes and significant self-reported improvements in oral health knowledge and skills. Irrespective of course type, students gained similar levels of oral health knowledge and skills following use of the resources. Nurses and care workers must be able to provide consistent standards of oral health care as a fundamental part of caring for patients. Validated as an effective learning and teaching package, it is recommended that these resources be used to strengthen the oral health content of entry-level nursing and aged care qualifications. Building the oral health capacity of nurses and care workers is one way of reversing oral health neglect and improving the quality of care provided to older people. © 2017 John Wiley & Sons Ltd.

Introduction Provision of oral health knowledge to the children by their teachers at the school level can prove to be more fruitful because it is the time period during which the children begin to learn the basic oral hygiene practices and are most prone to dental caries. Aim This study was carried out to assess the effect of training school teachers on oral hygiene status of 8-10 years old government school children of Udaipur city, India. Materials and Methods A total of nine school teachers and 279, 8-10 year old school children from two government schools were included in the study. The questionnaire on oral health knowledge and practice contained 17 questions to evaluate the knowledge and practice of children towards oral hygiene before and after the teachers training program. Baseline and six months post training data on oral health knowledge and practice was obtained by the questionnaire method. Baseline and six months post training data on oral hygiene status was obtained by OHI-S Index. Statistical analysis was done using software SPSS 22, the test used were McNemar’s test, paired t-test. Results Pre and post training data were compared and it was found that there was a significant improvement in oral health knowledge and practices of school teachers and children. Also oral hygiene status of school children was significantly improved after the program. Conclusion Results of the present study suggest that experiential learning is an effective school based oral health education method for improvement of oral hygiene in primary school children.

Viruses are the most abundant known infectious agents on the planet and are significant drivers of diversity in a variety of ecosystems. Although there have been numerous studies of viral communities, few have focused on viruses within the indigenous human microbiota. We analyzed 2 267 695 virome reads from viral particles and compared them with 263 516 bacterial 16S rRNA gene sequences from the saliva of five healthy human subjects over a 2- to 3-month period, in order to improve our understanding of the role viruses have in the complex oral ecosystem. Our data reveal viral communities in human saliva dominated by bacteriophages whose constituents are temporally distinct. The preponderance of shared homologs between the salivary viral communities in two unrelated subjects in the same household suggests that environmental factors are determinants of community membership. When comparing salivary viromes to those from human stool and the respiratory tract, each group was distinct, further indicating that habitat is of substantial importance in shaping human viromes. Compared with coexisting bacteria, there was concordance among certain predicted host–virus pairings such as Veillonella and Streptococcus, whereas there was discordance among others such as Actinomyces. We identified 122 728 virulence factor homologs, suggesting that salivary viruses may serve as reservoirs for pathogenic gene function in the oral environment. That the vast majority of human oral viruses are bacteriophages whose putative gene function signifies some have a prominent role in lysogeny, suggests these viruses may have an important role in helping shape the microbial diversity in the human oral cavity.

Mesenchymal stem cells (MSCs) are capable of regenerative and immunomodulatory functions in cell-based therapies in a variety of human diseases and injuries; however, their therapeutic efficacy and potential side effects remain major obstacles in clinical applications. We report here a 3D spheroid culture approach to optimize stem cell properties and therapeutic effects of human gingiva-derived mesenchymal stem cells (GMSCs) in mitigation of experimental oral mucositis. Under growth condition of ultra-low attachment, GMSCs spontaneously aggregated into 3D spheroids and exhibited distinct early stem cell phenotype characterized by elevated expression Stro-1 and CXC chemokine receptor 4 (CXCR-4) as well as OCT-4 and Nanog, 2 important transcriptional factors relevant to stem cell properties, and decreased expression of MSC-associated markers, including CD29, CD90, and CD105. Functionally, spheroid GMSCs are capable of enhanced multipotency and augmented secretion of several chemokines and cytokines relevant to cell migration, survival, and angiogenesis. More importantly, spheroid GMSCs expressed increased levels of reactive oxygen species, hypoxia-inducible factor (HIF)-1 and -2α, and manganese superoxide dismutase, which correlated with improved resistance to oxidative stress-induced apoptosis. Using an in vivo murine model of chemotherapy-induced oral mucositis, we demonstrated that spheroid-derived GMSCs possessed better therapeutic efficacy than their adherent cells in reversing body weight loss and promoting the regeneration of disrupted epithelial lining of the mucositic tongues. These findings suggest that 3D spheroid culture allows early stemness preservation and potentially precondition GMSCs for enhanced mitigation of oral mucositis. © Mary Ann Liebert, Inc.

Orthodontic treatment is highly popular for restoring functional and facial esthetics in juveniles and adults. As a downside, prevalence of biofilm-related complications is high. Objectives of this review are to (1) identify special features of biofilm formation in orthodontic patients and (2) emphasize the need for strong concerted action to prevent biofilm-related complications during orthodontic treatment. Literature on biofilm formation in the oral cavity is reviewed to identify special features of biofilm formation in orthodontic patients. Estimates are made of juvenile and adult orthodontic patient population sizes, and biofilm-related complication rates are used to indicate the costs and clinical workload resulting from biofilm-related complications. Biofilm formation in orthodontic patients is governed by similar mechanisms as common in the oral cavity. However, orthodontic appliances hamper the maintenance of oral hygiene and provide numerous additional surfaces, with properties alien to the oral cavity, to which bacteria can adhere and form a biofilm. Biofilm formation may lead to gingivitis and white spot lesions, compromising facial esthetics. Whereas gingivitis after orthodontic treatment is often transient, white spot lesions may turn into cavities requiring professional restoration. Complications requiring professional care develop in 15 % of all orthodontic patients, implying an annual cost of over US$500,000,000 and a workload of 1,000 full-time dentists in the USA alone. Improved preventive measures and antimicrobial materials are urgently required to prevent biofilm-related complications of orthodontic treatment from overshadowing its functional and esthetic advantages. High treatment demand and occurrence of biofilm-related complications requiring professional care make orthodontic treatment a potential public health threat.

This study aimed to assess changes in oral cancer patients' health-related quality of life (HRQOL) and the impact of disease stage on HRQOL scores. HRQOL data were collected from seven hospital-based centres using the Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N) version 4.0 instrument. The independent samples t-test, χ 2 test, and paired samples t-test were used to analyse the data. A total of 300 patients were recruited. The most common oral cancer sub-site was tongue and floor of mouth (42.6%). Surgical intervention (41.1%) was the most common treatment modality. Significant differences in ethnicity and treatment modality were observed between early and late stage patients. Pre-treatment HRQOL scores were significantly lower for late than early stage patients. At 1 month post-treatment, the functional and head and neck domains and the FACT-H&N (TOI) summary scores showed significant deterioration in both early and late stage patients. In contrast, the emotional domain showed a significant improvement for early and late stage patients at 1, 3, and 6 months post-treatment. Although HRQOL deterioration was still observed among early and late stage patients at 6 months post-treatment, this was not statistically significant. In conclusion, advanced disease is associated with poorer HRQOL. Although ethnic differences were observed across different disease stages, the influence of ethnicity on patient HRQOL was not evident in this study.

This qualitative study explored the impact on oral health-care knowledge, attitudes, and practices among 39 people living with HIV/AIDS (PLWHA) participating in a national initiative aimed at increasing access to oral health care. Personal values and childhood dental experiences, beliefs about the importance of oral health in relation to HIV health, and concerns for appearance and self-esteem were found to be determinants of oral health knowledge and practice. Program participation resulted in better hygiene practices, improved self-esteem and appearance, relief of pain, and better physical and emotional health. In-depth exploration of the causes for these changes revealed a desire to continue with dental care due to the dental staff and environmental setting, and a desire to maintain overall HIV health, including oral health. Our findings emphasize the importance of addressing both personal values and contextual factors in providing oral health-care services to PLWHA. PMID:22547879

Data were analyzed from a population-based, longitudinal sample of 8,650 U.S. children to (a) identify factors associated with or predictive of oral vocabulary size at 24 months of age and (b) evaluate whether oral vocabulary size is uniquely predictive of academic and behavioral functioning at kindergarten entry. Children from higher socioeconomic status households, females, and those experiencing higher-quality parenting had larger oral vocabularies. Children born with very low birth weight or from households where the mother had health problems had smaller oral vocabularies. Even after extensive covariate adjustment, 24-month-old children with larger oral vocabularies displayed greater reading and mathematics achievement, increased behavioral self-regulation, and fewer externalizing and internalizing problem behaviors at kindergarten entry.

Background How dental patients are affected by oral conditions can be described with the concept of oral health-related quality of life (OHRQoL). This concept intends to make the patient experience measurable. OHRQoL is multidimensional and Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact were suggested as its four dimensions and consequently four scores are needed for comprehensive OHRQoL assessment. When only the presence of dimensional impact is measured, a pattern of affected OHRQoL dimensions would describe in a simple way how oral conditions’ influence the individual. Objective By determining which patterns of impact on OHRQoL dimensions (Oral Function-Orofacial Pain-Orofacial Appearance-Psychosocial Impact) exist in prosthodontic patients and general population subjects, we aimed to identify in which combinations oral conditions’ functional, painful, aesthetical, and psychosocial impact occurs. Methods Data came from the Dimensions of OHRQoL Project with OHIP-49 data from 6,349 general population subjects and 2,999 prosthodontic patients in the Learning Sample (N=5,173) and the Validation Sample (N=5,022). We hypothesized that all 16 patterns of OHRQoL dimensions should occur in these individuals who suffered mainly from tooth loss, its causes and consequences. A dimension was considered impaired when at least one item in the dimension was affected frequently. Results The 16 possible patterns of impaired OHRQoL dimensions were found in patients and general population subjects in both Learning and Validation Samples. Conclusions In a four-dimensional OHRQoL model consisting of Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact, oral conditions’ impact can occur in any combination of the OHRQoL dimensions.

To analyse the relationship between oral bacteria and the health and functional status of the elderly. The bacteria species in the oral cavity of the elderly were examined. It was found that the bedridden subjects staying at two hospitals for long-term (HOBR) showed significantly lower detection rates of commensal bacteria species and significantly higher detection rates of Pseudomonas aeruginosa, of methicillin-resistant Staphylococcus aureus (MRSA) and of coagulase(-) Staph. aureus than those living independently (the independent). In addition, the detection rate of Haemophilus parainfluenzae in NUBR was discovered to be higher than that found in the independent. In HOBR, the detection rate of Ps. aeruginosa was significantly higher among in-patients who required continual care than those in need of partial care, while the detection rate of MRSA was significantly higher among in-patients with low serum albumin than those with normal serum albumin. Oral bacteria examination analysis proved that the risks of infection of some pathogenic bacteria species were correlated with functional status, physical function and nutritional state. Our study suggests that the oral bacteria, especially pathogenic bacteria were influenced by the functional status of the elderly and the type and quality of the facilities for the bedridden, physical function and nutritional state.

Prosthodontic treatment has a positive effect on oral health-related quality of life (OHRQoL); however, there is a paucity of studies assessing the impact of OHRQoL based on where in the mouth ("location") the treatment is performed. This exploratory study investigated the association of the location (anterior, posterior region) of prosthodontic treatment with magnitude and nature of OHRQoL changes. In this non-randomized prospective clinical study, 190 adult patients (17-83 years) were recruited at baseline and 104 were available for the follow-up analyses. Of those, 50 patients received treatment only in the posterior segment and 54 patients in both anterior and posterior regions. Treatment included conventional fixed partial prostheses, removable prostheses or a combination of both. OHRQoL was assessed with the German language version of the 49-item Oral Health Impact Profile (OHIP) at baseline and the questionnaire was repeated 4-6 weeks post-treatment. Magnitude and effect size of changes in summary and sub-scale scores were calculated and data analyzed. Patients experienced a substantially impaired OHRQoL (mean OHIP score: 32.3 points) at baseline and an improvement in OHRQoL of 6.8 OHIP points following treatment. This study showed a greater improvement in OHRQoL in patients treated in both regions compared to those treated in the posterior region alone, especially in the function and aesthetic domains. This explorative study suggests that OHRQoL improvement is affected by where prosthodontic treatment is performed in the mouth. Greater understanding of qualitative aspects of reconstructive therapies is needed for improved treatment planning and patient consent. Copyright © 2014 Japan Prosthodontic Society.

Clinical outcomes are worse in patients with COPD and chronic bronchitis. N-acetylcysteine (NAC) is commonly prescribed for such patients but with uncertain clinical benefits. We postulated that oral NAC, at much larger doses than those ordinarily prescribed, would improve clinical outcomes in a subset of patients with COPD and chronic bronchitis. The aim of this study was to determine whether very high-dose NAC would improve respiratory health status in patients with COPD and chronic bronchitis. Patients with COPD and chronic bronchitis were enrolled in a randomized, controlled, double-blinded trial. Patients received oral NAC (1,800 mg) or matching placebo twice daily for 8 weeks in addition to their usual respiratory medications. The primary outcome, respiratory health status, was assessed by changes in the St George's Respiratory Questionnaire. The effects of NAC on lung function and circulating markers of oxidative stress and inflammation were also evaluated. We terminated the study prematurely because new external information suggested the possibility of a safety issue. Of the planned 130 patients, 51 were randomized and 45 (22 in the placebo arm and 23 in the NAC arm) completed the study. There was no statistically significant difference between changes in the St George's Respiratory Questionnaire total score, comparing NAC to placebo (adjusted mean difference, 0.1 U; 95% CI, -7.8 to 8.18 U; P=0.97). There were also no significant NAC-related improvements in any of the secondary outcomes. In this 8-week trial, we were unable to show any clinical benefit from a very high dose of NAC in patients with COPD and chronic bronchitis.

Purpose Isometric progressive resistance oropharyngeal (I-PRO) therapy improves swallowing function; however, current devices utilize a single sensor that provides limited information or are prohibitively expensive. This single-subject study presents results of I-PRO therapy, detraining, and maintenance using the 5-sensor Madison Oral Strengthening Therapeutic (MOST) device combined with upper esophageal sphincter (UES) dilatation. Methods A 56-year-old female nurse who was 27 months post stroke and subsequent to traditional behavioral interventions and UES dilatations presented limited to gastrostomy tube intake only and expectorating all saliva. She completed 8 weeks of I-PRO therapy, 5 weeks of detraining, and 9 weeks of I-PRO maintenance (reduced frequency) followed by a third UES dilatation post intervention. Data included diet inventory, lingual pressures (MOST), lingual volume (magnetic resonance imaging), postswallow residue (videofl uoroscopy), UES and pharyngeal pressures (high-resolution manometry), and quality of life (QOL). Results Findings after 8 weeks of I-PRO therapy were progression to general oral diet, 15 lb weight gain, increased isometric pressures (Δ >16 kPa) with transference to swallowing pressures, increased lingual volume (8.3%), reduced pharyngeal wall residue (P = .03), increased pharyngeal pressures (Δ > 43 mm Hg) and increased UES opening (nadir) pressures (Δ > 9 mm Hg) with improved temporopressure coordination across the pharynx, and improved QOL. After detraining, decreased isometric pressures and reduced UES opening were noted. After I-PRO maintenance, isometric anterior lingual pressures returned to levels noted after the 8 weeks of intervention. Conclusion I-PRO therapy, facilitated by the MOST device combined with instrumental UES dilatation, improved swallow safety, increased oropharyngeal intake, and facilitated UES opening while enriching QOL.

Vildagliptin is a new oral antidiabetic agent that enhances pancreatic islet cell responsiveness to glucose. An extensive clinical program involving approximately 22,000 patients and 7000 patient-years of exposure to vildagliptin has shown that the agent is well tolerated and efficacious in improving glycemic control in patients with type 2 diabetes mellitus (T2DM). Monotherapy trials have shown that significant HbA1c lowering is accompanied by body weight-neutral and lipid-neutral effects, low risk of edema, and low risk of hypoglycemia. These characteristics make vildagliptin a favorable partner for combination therapy. Studies of vildagliptin as an add-on to metformin have shown significant improvements in glycemic control (comparable to that of thiazolidinedione add-on), with the combination being well tolerated and associated with low risks for hypoglycemia and adverse effects on weight or lipid levels. Good tolerability and clinically relevant improvements in glycemic control have also been observed with vildagliptin as an add-on treatment to sulfonylurea, thiazolidinedione, or insulin treatment or in initial combination treatment with pioglitazone. Improved β-cell function and glycemic control have been shown with vildagliptin in subjects with impaired glucose tolerance and in T2DM patients with mild hyperglycemia, with some evidence in the latter suggesting the potential for modifying disease course.

Global increase in patients seeking orthodontic treatment creates a demand for the use of acrylic resins in removable appliances and retainers. Orthodontic removable appliance wearers have a higher risk of oral infections that are caused by the formation of bacterial and fungal biofilms on the appliance surface. Here, we present the synthetic route for an antibacterial and antifungal organically-modified silicate (ORMOSIL) that has multiple methacryloloxy functionalities attached to a siloxane backbone (quaternary ammonium methacryloxy silicate, or QAMS). By dissolving the water-insoluble, rubbery ORMOSIL in methyl methacrylate, QAMS may be copolymerized with polymethyl methacrylate, and covalently incorporated in the pressure-processed acrylic resin. The latter demonstrated a predominantly contact-killing effect on Streptococcus mutans ATCC 36558 and Actinomyces naselundii ATCC 12104 biofilms, while inhibiting adhesion of Candida albicans ATCC 90028 on the acrylic surface. Apart from its favorable antimicrobial activities, QAMS-containing acrylic resins exhibited decreased water wettability and improved toughness, without adversely affecting the flexural strength and modulus, water sorption and solubility, when compared with QAMS-free acrylic resin. The covalently bound, antimicrobial orthodontic acrylic resin with improved toughness represents advancement over other experimental antimicrobial acrylic resin formulations, in its potential to simultaneously prevent oral infections during appliance wear, and improve the fracture resistance of those appliances.

Stunting Persists despite Optimal Feeding: Are Toilets Part of the Solution?

Children in developing countries have an average length-for-age that is already below the World Health Organization standard at birth and show a further decline in linear growth over the first 24 months of life; however, complementary feeding interventions have only a modest impact on growth. Children living in conditions of poor sanitation and hygiene are frequently exposed to pathogenic microbes through feco-oral transmission. Acute diarrhea represents only the tip of the 'enteric disease iceberg', with a substantial underlying burden of chronic, subclinical enteropathy. Environmental enteric dysfunction (EED) is characterized by disturbance in small intestinal structure and impaired gut barrier function, enabling microbial translocation and chronic systemic inflammation, which may impair growth. Gut damage appears to arise early in infancy and markers of intestinal inflammation, intestinal permeability and systemic immune activation are inversely associated with linear growth. Reducing feco-oral microbial transmission by improving water, sanitation and hygiene (WASH) may theoretically prevent or ameliorate EED and improve linear growth; ongoing trials are exploring this hypothesis. Given the complex interplay of factors leading to stunting, multisectoral interventions are likely required. Improving WASH in addition to infant feeding may be one approach to improve the growth and developmental potential of infants in developing countries. © 2015 Nestec Ltd., Vevey/S. Karger AG, Basel.

To control Medicaid costs, improve quality, and drive community engagement, the Oregon Health Authority introduced a new system of coordinated care organizations (CCOs). While CCOs resemble traditional Medicaid managed care, they have differences that have been deliberately designed to improve care coordination, increase accountability, and incorporate greater community governance. Reforms include global budgets integrating medical, behavioral, and oral health care and public health functions; risk-adjusted payments rewarding outcomes and evidence-based practice; increased transparency; and greater community engagement. The CCO model faces several implementation challenges. If successful, it will provide improved health care delivery, better health outcomes, and overall savings.

To evaluate and compare the effects of neuromuscular electrical stimulation (NMES) acting on the sensory input or motor muscle in treating patients with dysphagia with medullary infarction. Prospective randomized controlled study. Department of physical medicine and rehabilitation. Patients with dysphagia with medullary infarction (N=82). Participants were randomized over 3 intervention groups: traditional swallowing therapy, sensory approach combined with traditional swallowing therapy, and motor approach combined with traditional swallowing therapy. Electrical stimulation sessions were for 20 minutes, twice a day, for 5d/wk, over a 4-week period. Swallowing function was evaluated by the water swallow test and Standardized Swallowing Assessment, oral intake was evaluated by the Functional Oral Intake Scale, quality of life was evaluated by the Swallowing-Related Quality of Life (SWAL-QOL) Scale, and cognition was evaluated by the Mini-Mental State Examination (MMSE). There were no statistically significant differences between the groups in age, sex, duration, MMSE score, or severity of the swallowing disorder (P>.05). All groups showed improved swallowing function (P≤.01); the sensory approach combined with traditional swallowing therapy group showed significantly greater improvement than the other 2 groups, and the motor approach combined with traditional swallowing therapy group showed greater improvement than the traditional swallowing therapy group (P<.05). SWAL-QOL Scale scores increased more significantly in the sensory approach combined with traditional swallowing therapy and motor approach combined with traditional swallowing therapy groups than in the traditional swallowing therapy group, and the sensory approach combined with traditional swallowing therapy and motor approach combined with traditional swallowing therapy groups showed statistically significant differences (P=.04). NMES that targets either sensory input or motor muscle coupled with traditional therapy is conducive to recovery from dysphagia and improves quality of life for patients with dysphagia with medullary infarction. A sensory approach appears to be better than a motor approach. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

To assess the effects of aripiprazole once-monthly 400 mg (AOM 400) on clinical symptoms and global improvement in schizophrenia after switching from an oral antipsychotic. In a multicenter, open-label, mirror-image, naturalistic study in patients with schizophrenia (>1 year, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision [DSM-IV-TR] criteria), changes in efficacy measures were assessed during prospective treatment (6 months) with AOM 400 after switching from standard-of-care oral antipsychotics. During prospective treatment, patients were cross-titrated to oral aripiprazole monotherapy (1-4) weeks followed by open-label AOM 400 (24 weeks). Mean change from baseline of the open-label AOM 400 phase in Positive and Negative Syndrome Scale (PANSS) scores (total, positive and negative subscales) and Clinical Global Impression-Severity (CGI-S) scores; mean CGI-Improvement (CGI-I) score; and proportion of responders (≥30% decrease from baseline in PANSS total score or CGI-I score of 1 [very much improved] or 2 [much improved]) were assessed. PANSS and CGI-S scores improved from baseline (P<0.0001) and CGI-I demonstrated improvement at all time points. By the end of the study, 49.0% of patients were PANSS or CGI-I responders. In a community setting, patients with schizophrenia who were stabilized at baseline and switched to AOM 400 from oral antipsychotics showed clear improvements in clinical symptoms.

Malnutrition is a serious health concern for frail elderly people. Poor oral function leading to insufficient food intake can contribute to the development of malnutrition. In the present study, we explored the longitudinal association of malnutrition with oral function, including oral health status and swallowing function, in elderly people receiving home nursing care. Prospective observational cohort study with 1-year follow-up. Two mid-sized cities in Fukuoka, Japan from November 2010 to March 2012. One hundred and ninety-seven individuals, aged ≥ 60 years, living at home and receiving home-care services because of physical disabilities, without malnutrition. Oral health status, swallowing function, taking modified-texture diets such as minced or pureed foods, nutritional status, cognitive function, and activities of daily living were assessed at baseline. The associations between malnutrition at 1-year follow-up and these related factors were analyzed using a logistic regression model. Swallowing disorders [risk ratio (RR): 5.21, 95% confidence interval (95% CI): 1.65-16.43] were associated with malnutrition. On the other hand, oral health status did not have a direct association with malnutrition. Swallowing disorders may be associated with the incidence of malnutrition in elderly people receiving home-care. The findings indicate that maintaining swallowing function may contribute to the prevention of malnutrition in frail elderly people.

The aim of this study was to describe orofacial features and functions and oral health associated with Treacher Collins syndrome (TCS) in relation to the variable phenotypic expression of the condition. The Nordic Orofacial Test-Screening (NOT-S), MHC Questionnaire, MHC Observation chart and clinical examinations of nasal and pharyngeal conditions and chewing and swallowing function were used to assess 19 individuals aged 5-74 years (median 34 years). TCS severity scores were calculated by a clinical geneticist. Orofacial features characterizing the study group were altered profile, increased mandibular angle, narrow hypopharynx and facial asymmetry. Basic orofacial functions such as breathing, eating, facial expression and speech were affected in all subjects demonstrating orofacial dysfunction in at least two NOT-S domains (median NOT-S total score 4/12, range 2-7). Significant correlation was found between the TCS severity scores reflecting phenotypic expression and the NOT-S total scores reflecting orofacial function. Self-reported experience of dry oral mucosa was common. Overall, dental health was good with few carious lesions diagnosed, but considerable need for orthodontic treatment was documented. Altered orofacial features and functions in TCS are common and often persist into late adolescence and adulthood. The functional level was correlated with the phenotypic variability of the condition. The standard of oral health was satisfactory. The findings indicated that individuals with TCS are likely to require lifelong health services related to their oral condition.

Living with a child with a severe orofacial handicap: experiences from the perspectives of parents.

Orofacial functions include competences/abilities such as eating, breathing, speech/language, mimicry, as well as oral health, and disturbances are common in children with rare disorders. To describe parental experiences of orofacial function and needs in children with rare disorders, in-depth interviews focusing on orofacial function were carried out with 14 parents. Interviews were transcribed verbatim and analysed in open, axial (theoretical) and selective coding processes according to Grounded Theory. Two core categories emerged from data in the analysis: 'the vulnerable family' and 'support perceived from others'. The data indicated the importance of a balance between these two core categories: the strain caused by living in a family with a child with a severe disability/handicap, and the availability of perceived support from caregivers and significant others. This balance was necessary for the parents in developing self-reliance and in reconciling themselves to their life situations. Parents described orofacial dysfunction in terms of feeding and communication problems, needs for orthodontic treatment to reduce risk of trauma or improve chewing, and drooling. Oral health issues such as dental caries and gingivitis were not mentioned. Five aspects of good professional attitude were recognized: respect, involvement, continuity, knowledge, and availability.

Amelogenesis imperfecta refers a group of hereditary diseases affecting the teeth and can present a variety of clinical forms and appearances, compromising esthetic appearance. Amelogenesis imperfecta variably reduces oral health quality and can result in severe psychological problems. We present the management of an amelogenesis imperfecta Angle class III malocclusion case with speech, esthetics and functional problems. This is an example of the rarely presented delayed eruption with multiple morphologic dental alterations and edentulous maxilla.There are only a few available reports in which this method is used method to correct sagittal discrepancies in edentulous patients.Our treatment plan consisted of a preoperative diagnostic and prosthodontics phase (including preparation of guiding prosthesis), followed by a surgical phase of Le Fort I osteotomy, distraction osteogenesis to correct the malocclusion, implant insertion and a follow up final restorative phase. Our treatment strategy attempts to serve patient needs, achieving function and esthetics while also minimizing the risk of reconstruction failure. Treatment not only restored function and esthetics, but also showed a positive psychological impact and thereby improved perceived quality of life.

Efficacy of oral health promotion in primary care practice during early childhood: creating positive changes in parent's oral health beliefs and behaviors.

Nurse practitioners frequently provide care to children suffering from poor oral health. Creative approaches to impacting dental disease are needed due to the current lack of traditional dental providers. This study investigated the effects of oral health promotion provided by primary care providers on parental oral health beliefs and behaviors. Participants receiving standard oral care during two well child visits and two additional enhanced oral health visits (n=44) were compared to participants receiving standard oral care during two well child visits alone (n=40). Results revealed changes in parent's perception of the importance of oral care for their children's primary teeth compared to general healthcare needs (p<0.05), response to brushing their children's teeth (p<0.0001), confidence in brushing their teeth (p<0.05) and frequency of brushing (p<0.0001) in both groups. This small but important study shows that oral health programs in primary care can produce changes that can improve oral health outcomes. Parents and children exposed to oral health programs during their frequent well child care visits in the first years of life may help decrease the rate of early childhood caries and improve their quality of life.

The use of fenoterol in the treatment of preterm labor is associated with the risk of many complications in the mother and the fetus. We present a case of a multipara treated with oral fenoterol due to threatening preterm labor 14 weeks. At 35 weeks of gestation the fetus was diagnosed with hypertrophic cardiomyopathy with severe impairment of the right ventricle. The only factor that might have caused such a state of the fetal circulatory system was fenoterol, used from 21 weeks of gestation. After the withdrawal of the fenoterol the fetal right ventricular function improved gradually. However fetal cardiac hypertrophy persisted until the birth at 39 weeks of gestation. Concentric hypertrophy of the right ventricular wall and interventricular septum were confirmed in the newborn.

Electrotherapy and hyperbaric oxygen therapy have been added to physical therapy to treat patients with postsurgery and radiation sequelae. Problems of reduced oral opening and range of head movement, soft tissue necrosis, osteoradionecrosis, and delayed wound healing were addressed in 37 patients over a 3-year period. Of this group, 16 irradiated maxillary resection patients were specifically followed up to determine the effectiveness of the new modalities on improving reduced oral opening. Although healing and the quality of the soft tissues showed marked improvement there was no significant improvement in oral opening.

The availability of human insulin and subsequently insulin analogs that more closely mimic the body's physiology have contributed to increased safety in patients with diabetes and a greater role in patients with T2DM. This greater role is supported by clear evidence that early use of insulin in T2DM results in long-term improvements in glycemic control and beta-cell function compared with oral agents.

This study aimed to document the prevalence and patterns of oral phase oropharyngeal dysphagia (OPD) in preschool children with cerebral palsy (CP), and its association with mealtime duration, frequency and efficiency. Cross-sectional population-based cohort study of 130 children diagnosed with CP at 18-36 months ca (mean = 27.4 months, 81 males) and 40 children with typical development (mean = 26.2, 18 males). Functional abilities of children with CP were representative of a population sample (GMFCS I = 57, II = 15, III = 23, IV = 12, V = 23). Oral phase impairment was rated from video using the Dyspahgia Disorders Survey, Schedule for Oral Motor Impairment, and Pre-Speech Assessment Scale. Parent-report was collected on a feeding questionnaire. Mealtime frequency, duration and efficiency were calculated from a three day weighed food record completed by parents. Gross motor function was classified using the Gross Motor Function Classification System (GMFCS). Overall, 93.8% of children had directly assessed oral phase impairments during eating or drinking, or in controlling saliva (78.5% with modified cut-points). Directly assessed oral phase impairments were associated with declining gross motor function, with children from GMFCS I having a 2-fold increased likelihood of oral phase impairment compared to the children with TD (OR = 2.0, p = 0.18), and all children from GMFCS II-V having oral phase impairments. Difficulty biting (70%), cleaning behaviours (70%) and chewing (65%) were the most common impairments on solids, and difficulty sipping from a cup (60%) for fluids. OPD severity and GMFCS were not related to mealtime frequency, duration or efficiency, although children on partial tube feeds had significantly reduced mealtime efficiency. Oral phase impairments were common in preschool children with CP, with severity increasing stepwise with declining gross motor function. The prevalence and severity of oral phase impairments were significantly greater for most tasks when compared to children with typical development, even for those with mild CP. Children who were partially tube fed had significantly lower feeding efficiency, so this could be a useful early indicator of children needing supplementation to their nutrition (through increasing energy density of foods/fluids, or tube feeds).

National and professional organizations recommend oral health promotion in prenatal care to improve women's oral health. However, few prenatal programs include education about oral health promotion. The objective of this study was to determine if women receiving a brief, low-cost, and sustainable educational intervention entitled CenteringPregnancy Oral Health Promotion had clinically improved oral health compared to women receiving standard CenteringPregnancy care. Women attending CenteringPregnancy, a group prenatal care model, at 4 health centers in the San Francisco Bay Area, participated in this nonrandomized controlled pilot study in 2010 to 2011. The intervention arm received the CenteringPregnancy Oral Health Promotion intervention consisting of two 15-minute skills-based educational modules addressing maternal and infant oral health, each module presented in a separate CenteringPregnancy prenatal care session. The present analysis focused on the maternal module that included facilitated discussions and skills-building activities including proper tooth brushing. The control arm received standard CenteringPregnancy prenatal care. Dental examinations and questionnaires were administered prior to and approximately 9 weeks postintervention. Primary outcomes included the Plaque Index, percent bleeding on probing, and percent of gingival pocket depths 4 mm or greater. Secondary outcomes were self-reported oral health knowledge, attitudes (importance and self-efficacy), and behaviors (tooth brushing and flossing). Regression models tested whether pre to post changes in outcomes differed between the intervention versus the control arms. One hundred and one women participated in the study; 49 were in the intervention arm, and 52 were in the control arm. The control and intervention arms did not vary significantly at baseline. Significant pre to post differences were noted between the arms with significant improvements in the intervention arm for the Plaque Index, bleeding on probing, and pocket depths 4 mm or greater. Providing brief oral health education and skills-building activities within prenatal care may be effective in improving women's oral health during pregnancy. These findings provide support for developing a full-scale randomized clinical trial of the CenteringPregnancy Oral Health Promotion intervention. © 2017 by the American College of Nurse-Midwives.

Cognitive impairment is the gradual loss of one's ability to learn, remember, pay attention, and make decisions. Cognitively impaired elderly people are a challenging patient population for dental health care professionals and may be at higher risk of developing oral health diseases. The authors systematically reviewed interventions effective at improving dental health in patients with cognitive impairment and described research gaps remaining. In a comprehensive search of multiple databases, the authors identified 2,255 studies published in the English language from 1995 through March 2016. The authors included studies if the investigators evaluated oral health measures after an intervention in patients 65 years or older with cognitive impairment or dementia. Nine full-text articles met the criteria for inclusion. Only 1 study was a randomized control trial, whereas all others lacked appropriate controls. Investigators studied the effects of dental treatments, battery-powered devices for oral hygiene, and training of care staff members. Most interventions improved some aspect of the oral health of patients with dementia, and results were more pronounced when patients required assistance while performing oral hygiene tasks or had poor oral health at baseline. A basic care plan for patients with dementia should, at the minimum, match prevention strategies recommended for healthy elderly patients. Dental health care professionals should promote oral hygiene education for caregivers for elderly patients with cognitive impairment. There is a wide gap in knowledge regarding effective methods specifically to improve oral health in patients with dementia. Copyright © 2017 American Dental Association. Published by Elsevier Inc.

The purpose of this study is to examine factors that influence the diagnostic ability of dental students with regards to oral cancer and oral potentially malignant disorders. Dental students at different levels of study were directly interviewed to examine their oral cancer knowledge and diagnostic ability using a validated and pre-tested survey instrument containing validated clinical images of oral cancer and oral potentially malignant disorders. An oral cancer knowledge scale (0 to 31) was generated from correct responses on oral cancer general knowledge, and a diagnostic ability scale (0 to 100) was generated from correct selections of suspicious oral lesions. Knowledge scores ranged from 0 to 27 (mean 10.1 ± 6.0); mean knowledge scores increased with year of study; 5th year students had the highest mean knowledge score (19.1 ± 4.0), while 1st year students had the lowest (5.6 ± 3.5). Diagnostic ability scores increased with year of study and ranged from 0 to 88.5 % (mean 41.8 % ± 15.6). The ability to recognize suspicious oral lesions was significantly correlated with knowledge about oral cancer and oral potentially malignant disorders (r = 0.28; P < 0.001). There is a need to improve oral cancer education curricula; increasing students' contact with patients who have oral lesions including oral cancer will help to improve their future diagnostic ability and early detection practices.

Provision of oral health care in India, especially for the underprivileged is limited due to inadequate finances and manpower. Resources of dental colleges in such a scenario can be utilized to provide prevention oriented oral health care. To improve the oral health status of children at an institute in Nellore district of Andhra Pradesh, India, through prevention based comprehensive dental health care program (CDHP). A longitudinal institution based interventional study conducted among the primary grade children (n=162). Baseline data collection included (i) basic demographic data (ii) body mass index (BMI) (iii) assessment of the dentition status and treatment needs according to WHO 1997 criteria. The CDHP included group based dental health education, professional oral prophylaxis, weekly (0.2%) sodium fluoride mouth rinse program, biannual application of topical fluoride (1.23% APF), pit and fissure sealants for all first permanent molars and provision of all necessary curative services. Mean treatment requirements per child decreased at 18 months. New caries lesions developed among four children. BMI of children with decay was seen to improve significantly after instituting the CDHP. CDHP is effective in overall improvement of general and oral health. In resource limited countries like India, such programs organized by dental schools can improve oral health.

Roles of aging or immune responses mediated by Toll-like receptors and natural killer cell in the onset or progression of human candidiasis remain unclear. This study was designed to elucidate the roles using peripheral blood mononuclear cells from healthy donors and patients with oral candidiasis. Subjects tested were healthy volunteers and patients who visited Dental Clinical Division of Hokkaido University Hospital. The patients with oral candidiasis included 39 individuals (25-89 years of age) with major complaints on pain in oral mucosa and/or dysgeusia. Healthy volunteers include students (25-35 years of age) and teaching staffs (50-65 years of age) of Hokkaido University Graduate School of Dental Medicine. Functions of Toll-like receptors 2 and 4 were downregulated significantly and the natural killer activity was slightly, but not significantly downregulated in aged healthy volunteers compared with healthy young volunteers. Functions of Toll-like receptors 2 and 4 and the natural killer activity were significantly downregulated in patients with oral candidiasis compared with healthy volunteers. Downregulation of functions of Toll-like receptors 2 and 4 as well as natural killer activity is suggested to be associated with the onset or progression of oral candidiasis in human. © 2015 John Wiley & Sons A/S.

The oral conditions of adult edentulous patients with ectodermal dysplasia (ED) often lead to decreased physical and psychological health, and the negative effects can become as extreme as social and psychological isolation. However, restoring oral function of adult edentulous patients with ED using zygomatic implants (ZIs) or conventional implants (CIs) remains challenging for dentists because of the severe atrophy of these patients' alveolar ridges. This report describes 2 cases of adult edentulous siblings with ED; they exhibited severe alveolar bone atrophy and were treated with ZIs and CIs as bases to augment the bone in their anterior jaws. For these patients, bone augmentation was completed with an autogenous fibular graft. Although there was mild evidence of bone graft resorption in the maxilla, the bone augmentation procedures were successful in the 2 patients. Effective osseointegration of the implants was obtained. After placement, the functional and esthetic results of the oral rehabilitation were acceptable. More importantly, restoration of the patients' oral function enhanced their self-confidence and self-esteem. Therefore, restoring oral function in adult patients with ED and edentulous jaws using ZIs and CIs as the bases for bone augmentation is an effective approach. Crown Copyright © 2015.

2016-11-01

Globocan 2012 reports the global oral cancer incidence of 300,373 new oral cancer cases annually, contributing to 2.1 % of the world cancer burden. The major well-established risk factors for oral cancer include tobacco, betel/areca nut, alcohol and high-risk oncogenic human papilloma virus (HPV) 16/18. However, only 5-10 % of individuals with high-risk lifestyle develop oral cancer. Thus, genomic variants in individuals represented as single nucleotide polymorphisms (SNPs) influence susceptibility to oral cancer. With a view to understanding the role of genomic variants in oral cancer, we reviewed SNPs in case-control studies with a minimum of 100 cases and 100 controls. PubMed and HuGE navigator search engines were used to obtain data published from 1990 to 2015, which identified 67 articles investigating the role of SNPs in oral cancer. Single publications reported 93 SNPs in 55 genes, with 34 SNPs associated with a risk of oral cancer. Meta-analysis of data in multiple studies defined nine SNPs associated with a risk of oral cancer. The genes were associated with critical functions deregulated in cancers, including cell proliferation, immune function, inflammation, transcription, DNA repair and xenobiotic metabolism.

The quality of oral care is important in limiting the emergence of ventilator-associated pneumonia (VAP) in intubated patients. Our main objective was to measure the quality improvement in oral care following the implementation of a new oral care protocol. We also monitored VAP rates. This was a cohort study of patients in 5 adult ICUs covering different specialties. During period 1, caregivers used a foam stick for oral care and during period 2 a stick and tooth brushing with aspiration. Oral chlorhexidine was used during both periods. The caregivers rated improvement in oral health on the basis of 4 criteria (tongue, mucous membranes, gingivae, and teeth). Caregiver satisfaction was also assessed. The incidence of VAP was monitored. A total of 2,030 intubated patients admitted to intensive care units benefited from oral care. The patient populations during the 2 periods were similar with regard to demographic data and VAP potential risk factors. Oral health was significantly better from the third day of oral care in period 2 onward (period 1, 6.4 ± 2.1; period 2, 5.6 ± 1.8; P = .043). Caregivers found the period 2 protocol easier to implement and more effective. VAP rates decreased significantly between the 2 periods (period 1, 12.8%; period 2, 8.5%; P = .002). Our study showed that the implementation of a simple strategy improved the quality of oral care of patients in intensive care units, and decreased VAP rates.

Serious systemic infections may occur during cancer chemotherapy due to disturbances in the oropharyngeal and gastrointestinal microflora, impaired mucosal barrier functions and immunosuppression. Bacteria may spread from the gastrointestinal tract to the regional lymph nodes. The routes for bacterial spread from the oral cavity are less well known. In the present study we investigated changes in the oral and intestinal microfloras in rats given 50 mg/kg 5-fluorouracil (5-FU) i.v. for 6 days. Bacterial dissemination to the lymph nodes draining the oral cavity and the lymph nodes draining the gastrointestinal tract was examined. Effects of adding the probiotic strain Lactobacillus plantarum 299v in the drinking water to the rats were measured. 5-FU treatment caused an increase in the number of facultative and strictly anaerobic bacteria in biopsies from the oral cavity and an increase in the number of facultative anaerobes in the large intestine. The proportion of facultative gram-negative rods increased in both the oral cavity and intestine. Bacteria translocated to both the cervical and mesenteric lymph nodes in untreated animals and increased in numbers after 5-FU treatment due to an increase in the number of facultative gram-negative rods. Treatment with L. plantarum 299v improved food intake and body weight in 5-FU-treated rats. It also reduced the 5-FU-induced raise in the total numbers of facultative anaerobes in the intestine, but did not reduce translocation and did not prevent diarrhea. This study reinforces the oral cavity, along with the gastrointestinal tract, as a source for bacterial dissemination. The use of probiotic bacteria may reduce some side effects of 5-FU treatment.

Spasticity is a major problem for the rehabilitation team. Physiotherapy is a vital component of therapy. Oral medication and other modalities such as heat, cold, ultrasound, electrical stimulation, and surgery (neuro-surgical or orthopedic) can also be used. The aim of this study was to compare the effects of hydrotherapy on spasticity and Functional Independence Measure (FIM) scores of patients with spinal cord injury (SCI). This is a control case matched study. Twenty SCI patients were divided into 2 groups and matched for age, gender, injury time, Ashworth scores, oral baclofen intake, American Spinal Injury Association, and FIM scores. The control group received passive range of motion exercise twice a day and oral baclofen for 10 weeks. The study group also received passive range of motion and oral baclofen, as well as 20 min of water exercises (at 71 degrees F, full immersion) 3 times per week. The authors evaluated spasm severity, FIM scores, oral baclofen intake, and Ashworth scales, between groups at the beginning and at the end of the treatment period. Both groups demonstrated a significant increase in FIM scores. However, the hydrotherapy group demonstrated a larger increase (P < 0.0001) than the control group. There was a statistically significant decrease in oral baclofen intake in the hydrotherapy group (P < 0.01). There was no statistical change in the control group. Spasticity was evaluated by the Ashworth scale. There was a statistical improvement in each group (P < 0.01, P < 0.02). However, when compared to the control group, the use of hydrotherapy produced a significant decrease in spasm severity (P < 0.02). Side effects are often seen when using oral drug treatment for spasticity. Adding hydrotherapy to the rehabilitation program can be helpful in decreasing the amount of medication required. Future studies must evaluate benefits of hydrotherapy for rehabilitation.

Background: Research on oral health contributes to improved health outcomes; it is an indispensable tool in health policy. But how to fill the gaps in research oral health and to strengthen its capacity is the question. The main objective of the present study is to identify the current status of oral health research and potential strategies, thereby strengthening the research infrastructure and capacity. Delphi consultation, in the perspective of assisting decision-makers to identify strategies to promote better research on oral health in Africa, was initiated. Design and Methods: The panels of 30 experts were asked to complete the questionnaire with 42 items into four groups by web survey. Each indicator statement was considered to be in consensus if the expert's opinion rating was of “A or B” for more than 75% in a scale of seven categories. Quantitative analysis was made from the answers of Delphi round. Results: There was a strong consensus about three items concerning the role of oral health research, the development of research policy for oral health going through an effective governance of research institutes, migration of researchers and fund raising. Conclusion: This study shows strong many dispersal opinions by experts, but highlights the need for to improve the effectiveness of oral health research capacity strengthening activities. Africa's researchers, policy makers and partners will have to give special attention to ensuring that knowledge generated from oral health research is acted on to improve health for all.

2016-12-01

This pilot study evaluated a dental intervention for employees with disabilities by measuring changes in self-rated oral health, dental behaviours and oral health-related quality of life (OHRQol). Consenting employees with disabilities (≥18years) at two worksites in South Australia underwent dental examinations at baseline, three and six months. Referrals were arranged as needed to public dental clinics. At one and two months a dental hygienist provided group oral health education to the employees. Employees' demographics, self-rated oral health, dental behaviours and OHRQol were collected via face-to-face interviews. Of the 39 referred employees, 28 (72%) of them completed the recommended treatment. Self-rated oral health improved and there were significant reductions in the prevalence of oral health impact on quality of life (percentage of employees reporting 1+ items fairly/very often) from 27% to 11% (McNemar's test, p<0.05); the extent of impact (mean number of items reported fairly/very often) from 1.3 to 0.6 and the severity of impact (mean of summed OHIP item scores) from 3.6 to 1.8 (paired t-tests, p<0.01). As this pilot study indicates that enabling urgent referral for treatment and regular oral health education can improve OHRQol and self-rated oral health among employees with disabilities, a larger study with a control group should be undertaken.

Dysphagia, or difficulty swallowing, often occurs secondary to conditions such as stroke, head injury or progressive disease, many of which increase in frequency with advancing age. Sarcopenia, the gradual loss of muscle bulk and strength, can place older individuals at greater risk for dysphagia. Data are reported for three older participants in a pilot trial of a tongue-pressure training therapy. During the experimental therapy protocol, participants performed isometric strength exercises for the tongue as well as tongue pressure accuracy tasks. Biofeedback was provided using the Iowa Oral Performance Instrument (IOPI), an instrument that measures tongue pressure. Treatment outcome measures show increased isometric tongue strength, improved tongue pressure generation accuracy, improved bolus control on videofluoroscopy, and improved functional dietary intake by mouth. These preliminary results indicate that, for these three adults with dysphagia, tongue-pressure training was beneficial for improving both instrumental and functional aspects of swallowing. The experimental treatment protocol holds promise as a rehabilitative tool for various dysphagia populations. PMID:19281066

To evaluate the course of health-related quality of life (HRQOL) from diagnosis to 2 years follow-up in patients with head and neck cancer (HNSCC) treated with chemoradiation (CRT). 164 patients completed the EORTC QLQ-C30 and QLQ-H&N35 questionnaires 1 week before and 6 weeks and 6, 12, 18, and 24 months after CRT. Patients were compared to a reference group. A linear mixed-model analysis was used to assess changes in HRQOL over time, and whether this was associated with age, gender, comorbidity, and tumor sublocation. Significant differences for the majority of HRQOL scales were observed between patient and reference group at baseline, and follow-up. The course of HRQOL was different for survivors compared to non-survivors. In survivors, improvement over time was observed (in global quality of life, physical, role, and social function, fatigue, pain, swallowing, speech, social eating, and social contacts), while in non-survivors the pattern over time was either no changes in HRQOL or a deterioration (in physical function, social eating and contacts). In both survivors and non-survivors, emotional functioning improved after treatment, but deteriorated in the longer term. Patients with comorbidity reported worse physical function, and patients with oral/oropharyngeal cancer (compared to hypopharyngeal/laryngeal cancer) reported more oral pain and sexual problems, but fewer speech problems. The course of HRQOL of HNSCC patients during the first 2 years after CRT is different for survivors compared to non-survivors and is associated with comorbidity and tumor subsite.

The human mouth: oral functions in a social complexity perspective.

PubMed

Eriksen, Harald M; Dimitrov, Vladimir

2003-06-01

In the dental and medical literature, the mouth and oral functions are usually presented in a biomedical context. However, there may be a need for a broader perspective if we are to appreciate the importance of the human mouth as an organ with diverse functions. The paradigm of complexity appears to be of relevance in our understanding the social and psychological characteristics of the human mouth in addition to its biological functions. Examples such as the pleasures of taste, social aspects of eating, the importance of linguistics and communication are illustrations of some of the social and psychological aspects of oral functions. Professional knowledge related to such issues is important in our understanding the patient's priorities and in performing the relevant diagnosis and treatment planning.

Pregnancy is a natural process that may create some changes in different parts of the body including the oral cavity. These changes will lead to oral diseases if enough and timely care of oral cavity is not taken. Women may experience increased gingivitis or pregnancy gingivitis beginning in the second or third month of pregnancy that increases in severity throughout the duration of pregnancy. To motivate the patient toward oral health and implement the needed prophylactic measures, a longitudinal study was planned to observe the effect of oral health education during pregnancy on knowledge, attitude, practice, oral health status, and treatment needs (TNs) of pregnant women belonging to different socioeconomic groups. A longitudinal study was conducted among 112 pregnant women belonging to different socioeconomic groups to assess the effect of oral health education on knowledge, attitude, practice, oral health status, and TNs. The demographic details, knowledge, attitude, and practice of pregnant women, and oral health status were collected through a predesigned questionnaire by a principal investigator through an interview. Oral health examination was carried out to assess oral health status using revised World Health Organization Proforma 1997, and oral health education was given through PowerPoint presentation to the participants in local language, i.e., Marathi, after collecting the baseline data. Reinforcement of oral health education and blanket referral was done at 14th week, and follow-up data were collected at 28th week of gestation. The demographic details, such as age, sex, education, occupation, income, and the questions based on knowledge, attitude, and practice among participants were analyzed using number, percentage, and mean. At baseline, knowledge was limited, attitude was positive, while the practice was poor regarding oral health care during pregnancy in pregnant women belonging to different socioeconomic groups. After oral health education and blanket referral, at 28th week of gestation, knowledge regarding oral health care improved drastically, attitude toward oral health became more positive, whereas practice did not change much among all the pregnant women belonging to different socioeconomic groups, probably indicating sociocultural influences. Intensive oral health education during pregnancy leads to drastic improvement in knowledge and attitude. Practice, gingival health, and the number of filled teeth also improved to some extent. Regular oral health education programs should be conducted at community level among pregnant woman to reduce the burden of oral diseases.

The study's purpose was to determine if parental dental functional-health-literacy (FHL) related to child oral health; a secondary aim was to assess if errors in completing the questionnaire related to FHL and child oral health. Parents of pediatric clinic children (N=101) completed questionnaires; dental caries indices were recorded. Higher FHL was negatively correlated with worse child caries (r=-0.23), but not subjective oral health. Mean FHL seemed to differ by skip pattern (p=0.087), indicating it may be a potential FHL proxy. PMID:22685950

Purpose To investigate potential associations among executive, physical and food functions in the acute phase after stroke. Methods This is a cross-sectional study that evaluated 63 patients admitted to the stroke unit of a public hospital. The exclusion criteria were other neurological and/or psychiatric diagnoses. The tools for evaluation were: Mini-Mental State Examination and Frontal Assessment Battery for cognitive functions; Alberta Stroke Program Early CT Score for quantification of brain injury; National Institutes of Health Stroke Scale for neurological impairment; Modified Rankin Scale for functionality, and the Functional Oral Intake Scale for food function. Results The sample comprised 34 men (54%) and 29 women with a mean age of 63.6 years. The Frontal Assessment Battery was significantly associated with the other scales. In multivariate analysis, executive function was independently associated with the Functional Oral Intake Scale. Conclusion Most patients exhibited executive dysfunction that significantly compromised oral intake.

When tonsillar hypertrophy obstructing the airway is encountered in a child with a repaired cleft palate and velopharyngeal insufficiency, the surgeon may opt for tonsillectomy to relieve the airway obstruction, with possible effects on velopharyngeal closure. The aim of this study was to assess the impact of hypertrophied tonsils on velopharyngeal function in children with repaired cleft palate and to measure the effect of tonsillectomy on velopharyngeal closure and speech resonance. Case series. Twelve children with repaired cleft palate and tonsillar hypertrophy underwent tonsillectomy to relieve airway obstruction. Preoperative and postoperative evaluation of velopharyngeal function was performed. Auditory perceptual assessment of speech and nasalance scores were measured, and velopharyngeal closure was evaluated by flexible nasopharyngoscopy. Preoperative impairment of velopharyngeal function was detected. However, significant postoperative improvement of speech parameters (hypernasality, nasal emission of air, and weak pressure consonants measured with auditory perceptual assessment) was achieved, and the overall postoperative nasalance score was improved significantly for nasal and oral sentences. Reduction of velopharyngeal gap size was detected after removal of hypertrophied tonsils. Although the improvement of velopharyngeal closure was not significant, three cases demonstrated complete postoperative closure with no gap. Hypertrophied tonsils may impair velopharyngeal function in children with repaired cleft palate, and tonsillectomy is beneficial for such patients as it can improve the velopharyngeal closure and speech resonance. Secondary corrective surgery may be avoided in some cases after tonsillectomy. Copyright © 2012 The American Laryngological, Rhinological, and Otological Society, Inc.

Objective: To investigate the clinical effect of compound monoammonium glycyrrhizinate combined with dandelion in the treatment of acute paraquat poisoning. Methods: A total of 80 patients with acute paraquat poisoning who were admitted to our hospital were enrolled as study subjects and randomly divided into routine treatment group (38 patients) and traditional Chinese medicine (TCM) group (42 patients) . The patients in the TCM group were given compound monoammonium glycyrrhizinate and dandelion in addition to the treatment in the control group. Serum alanine aminotransferase (ALT) , total bilirubin (TBil) , blood urea nitrogen (BUN) , creatinine (Cr) , and arterial blood lactate (Lac) and partial pressure of oxygen (PaO 2 ) during different time periods on day 3, 7, and 9 of treatment were observed in both groups, and ulceration of oral mucosa, pulmonary fibrosis, multiple organ dysfunction syndrome (MODS) , and mortality were compared between the two groups. Results: On days 3, 7, and 9 of treatment, the routine treatment group had significantly higher serum ALT, TBil, BUN, Cr, and arterial blood Lac than the TCM group. The routine treatment group had significantly lower arterial blood PaO 2 than the TCM group, while the TCM group had significantly lower incidence rates of ulceration of oral mucosa, pulmonary fibrosis, and MODS and a significantly lower mortality rate than the routine treatment group ( P <0.05) . Conclusion: In the treatment of patients with acute paraquat poisoning, compound monoammonium glycyrrhizinate combined with dandelion can effectively improve organ function, reduce the incidence of pulmonary fibrosis and MODS, improve the healing rate of oral ulcer, improve prognosis, and reduce mortality rate.

In the past 18 months, the U.S. Food and Drug Administration approved macitentan, riociguat, and treprostinil as oral agents for the treatment of pulmonary arterial hypertension (PAH); riociguat also became the first agent approved for the treatment of chronic thromboembolic pulmonary hypertension (CTEPH). These new agents are welcome additional therapeutic options for PAH and CTEPH. However, their use can be complicated by potential drug interactions, adverse effects, dosing complexity, and cost. Macitentan, the newest endothelin receptor antagonist, showed significant benefits in a long-term event-driven trial of morbidity and mortality. Dosed once daily and with minimal liver toxicity, it has potential drug interactions with potent CYP 3A4 inhibitors and inducers, and can decrease hemoglobin levels. Riociguat is approved for PAH and clinically inoperable CTEPH to improve exercise capacity and functional status. Riociguat requires dose titration beginning with 1 mg up to 2.5 mg three times a day, as tolerated, and should be used with caution in patients with underlying risk factors for systemic hypotension. Oral treprostinil, approved to improve exercise capacity in PAH, is associated with gastrointestinal side effects and headaches that are often dose limiting. Doses can begin with 0.125 mg or 0.25 mg twice a day with gradual increases on up to a weekly basis, as tolerated. Thrice daily dosing and administration with a meal can improve tolerance. These newer agents represent advances, but their specific roles in relation to pre-existing therapies are undergoing further evaluation. Therefore, close collaboration with clinicians at centers with therapeutic expertise is highly recommended to optimize patient outcomes.

To determine the associations between autism developmental profiles and cooperation with an oral health screening among preschool children with autism spectrum disorders (ASDs). A random sample of Special Child Care Centres registered with the Government Social Welfare Department in Hong Kong was selected (19 out of 37 Centres). All preschool children with ASDs were invited to participate in the oral health survey and 347 children agreed to participate (among 515 invited). A checklist of autism developmental profiles: (1) level of cognitive functioning, (2) social skills development, (3) communication skills development, (4) reading skills and (5) challenging behaviours was ascertained. Feasibility of conducting oral health screening in preschool children with ASDs was associated with their cognitive functioning (p = 0.001), social skills development (p = 0.002), communication skills development (p < 0.001), reading skills (p < 0.001) and challenging behaviours (p = 0.06). In regression analyses accounting for age (in months) and gender, inability to cooperate with an oral health screening was associated with high level of challenging behaviours (OR 10.50, 95 % CI 2.89-38.08, p < 0.001) and reduced cognitive functioning (OR 5.29, 95 % CI 1.14-24.61, p = 0.034). Age (in months) was positively associated with likelihood of cooperative behaviour with an oral health screening (OR 1.06, 95 % CI 1.03, 1.08, p < 0.001). Feasibility of conducting population-wide oral health screening among preschool children with ASDs is associated with their developmental profiles; and in particular levels of cognitive functioning, and challenging behaviours.

Background. Many women experience sexual dysfunction where there are orgasm disorders and sexual difficulties. Ashwagandha (Withania somnifera) is a herb known to improve the body's physical and psychological condition. Objective. The purpose of the study was to determine the efficacy and safety of a high-concentration ashwagandha root extract (HCARE) supplementation for improving sexual function in healthy females. Methods. In this pilot study, 50 study subjects were randomized to either (i) HCARE-treated group or (ii) placebo- (starch-) treated group. The subjects consumed either HCARE or placebo capsules of 300mg twice daily for 8 weeks. Sexual function was assessed using two psychometric scales, the Female Sexual Function Index (FSFI) Questionnaire and the Female Sexual Distress Scale (FSDS), and by the number of total and successful sexual encounters. Results. The analysis indicates that treatment with HCARE leads to significantly higher improvement, relative to placebo, in the FSFI Total score (p < 0.001), FSFI domain score for “arousal” (p < 0.001), “lubrication” (p < 0.001), “orgasm” (p = 0.004), and “satisfaction” (p < 0.001), and also FSDS score (p < 0.001) and the number of successful sexual encounters (p < 0.001) at the end of the treatment. Conclusions. This study demonstrated that oral administration of HCARE may improve sexual function in healthy women. The present study is registered in the Clinical Trial Registry, Government of India, with a number CTRI/2015/07/006045. PMID:26504795

Although low-calorie diets (LCD) improve glucose regulation, it is unclear if interval exercise (INT) is additive. We examined the impact of an LCD versus LCD + INT training on ß-cell function in relation to glucose tolerance in obese adults. Twenty-six adults (Age: 46 ± 12 year; BMI 38 ± 6 kg/m²) were randomized to 2-week of LCD (~1200 kcal/day) or energy-matched LCD + INT (60 min/day alternating 3 min at 90 and 50% HRpeak). A 2 h 75 g oral glucose tolerance test (OGTT) was performed. Insulin secretion rates (ISR) were determined by deconvolution modeling to assess glucose-stimulated insulin secretion ([GSIS: ISR/glucose total area under the curve (tAUC)]) and ß-cell function (Disposition Index [DI: GSIS/IR]) relative to skeletal muscle (Matsuda Index), hepatic (HOMA-IR) and adipose (Adipose-IR fasting ) insulin resistance (IR). LCD + INT, but not LCD alone, reduced glucose and total-phase ISR tAUC (Interactions: p = 0.04 and p = 0.05, respectively). Both interventions improved skeletal muscle IR by 16% ( p = 0.04) and skeletal muscle and hepatic DI (Time: p < 0.05). Improved skeletal muscle DI was associated with lower glucose tAUC ( r = -0.57, p < 0.01). Thus, LCD + INT improved glucose tolerance more than LCD in obese adults, and these findings relate to ß-cell function. These data support LCD + INT for preserving pancreatic function for type 2 diabetes prevention.

Formal agreement studies on interpretation of the videofluoroscopic swallowing study (VFSS) procedure among speech-language pathologists, radiology house officers, and staff radiologists have not been pursued. Each of these professions participates in the procedure, interprets the examination, and writes separate reports on the findings. The aim of this study was to determine reliability of interpretation between and within the disciplines and to determine if structured training improved reliability. Thirteen speech-language pathologists (SLPs), ten diagnostic radiologists (RADs) and twenty-one diagnostic radiology house officers (HOs) participated in this study. Each group viewed 24 VFSS samples and rated the presence or absence of seven aberrant swallowing features as well as the presence of dysphagia and identification of oral dysphagia, pharyngeal dysphagia, or both. During part two, the groups were provided with a training session on normal and abnormal swallowing, using different VFSS samples from those in part one, followed by re-rating of the original 24 VFSS samples. A generalized estimating equations (GEE) approach with a binomial link function was used to examine each question separately. For each cluster of tests, as example, all pairwise comparisons between the three groups in the pretraining period, a Hochberg's correction for multiple testing was used to determine significance. A GEE approach with a binomial link function was used to compare the premeasure to postmeasure for each of the three groups of raters stratified by experience. The primary result revealed that the HO group scored significantly lower than the SLP and RAD group on identification of the presence of dysphagia (p = 0.008; p = 0.001, respectively), identification of oral phase dysphagia (p = 0.003; p = 0.001, respectively), and identification of both oral and pharyngeal phase dysphagia, (p = 0.014, p = 0.001, respectively) pretraining. Post training there was no statistically significant difference between the three groups on identification of dysphagia and identification of combined oral and pharyngeal dysphagia. Formal training to identify oropharyngeal dysphagia characteristics appears to improve accuracy of interpretation of the VFSS procedure for radiology house officers. Consideration to include formal training in this area for radiology residency training programs is recommended.

Physical functioning declines with advancing age and compounds malnutrition, common in elderly populations. A dual-intervention combining oral nutritional support and exercise may delay these changes. Our aims were to assess whether exercise combined with oral nutritional support (ONS) has greater improvements on physical functioning, quality of life and nutritional status than nutrition intervention alone in nutritionally vulnerable older adults. Three electronic databases were searched for randomised controlled trials of older adults judged to be: sarcopenic, cachexic, frail, malnourished, and/or at risk of malnutrition, receiving ONS and exercise compared to nutrition intervention alone. Meta-analyses were performed using a fixed-effect model to calculate standardised mean difference (SMD) (hand-grip strength, limb strength, gait speed, timed up-and-go test (TUG), physical activity level and fat-free mass) or relative risk (hospitalisation) with 95% confidence intervals (CIs). Eleven studies (n = 1459 participants) were included. ONS and exercise interventions varied considerably between studies. There was very low quality evidence that exercise combined with ONS compared to nutrition intervention alone resulted in significant improvements in limb strength (SMD = 0.33; 95% CI 0.13-0.53; P = 0.001) but low quality evidence of no effect on fat-free mass (SMD = -0.05; 95% CI -0.27 to 0.18; P = 0.70), physical activity level (SMD = 0.04; 95% CI -0.26 to 0.33; P = 0.81) and TUG (mean difference = -0.80; 95% CI -2.06 to 0.47; P = 0.22). Moderate quality evidence from a small number of studies found no effect on handgrip strength and QOL. Low quality evidence of faster gait speeds were found in participants receiving ONS alone compared to combined intervention (SMD = 0.38; 95% CI 0.19 to 0.56; P < 0.0001). Combining exercise with ONS may provide additional improvements to muscle strength but had no effect on other measures of physical functioning, nutritional status or morbidity in nutritionally vulnerable older adults.

Oncological treatment can cause changes in the oral cavity compromising oral functions. The aim of the study was, based on a systematic review, to draft a guide directed at the team of health professionals involved in the oral care of oncological patients. A systematic search of the literature was performed for articles published between 2000 and April 2017. Searches were made of electronic databases and hand search. The inclusion criteria were systematic reviews of randomized clinical trials (RCTs) and RCTs published in English, involving pediatric and adult oncological patients and focused on the prevention and treatment of oral complications as well as studies addressing the maintenance of oral health. Among the 1237 studies identified, 129 were pre-selected and 54 were selected to form the basis for the clinical guide. The studies analyzed stress the need for oral assessments as well as preventive and curative actions prior to oncological treatment. To minimize the severity of oral problems, the studies emphasize daily oral care, the treatment of xerostomia with saliva substitute and hydration, and low-level laser therapy, nystatin, acyclovir, respectively, for the prevention and treatment of oral mucositis, oral candidiasis, and infection by herpes simplex virus. Thus, the guide produced addresses oral assessments and professional and home care before, during, and after oncological treatment. The guide drafted has the function of assisting health professionals involved in the oral care of patients with cancer, enabling the prevention or treatment of oral complications stemming from oncological treatment.

Clefts of the lip and/or palate (CLP) are oral-facial defects that affect health and overall quality of life. CLP patients often need multidisciplinary treatment to restore oral function and esthetics. This paper describes the oral rehabilitation of a CLP adult patient who had maxillary bone and tooth loss, resulting in decreased occlusal vertical dimension. Functional and cosmetic rehabilitation was achieved using a maxillary removable partial denture (RPD) attached to telescopic crowns. Attachment-retained RPDs may be a cost-effective alternative for oral rehabilitation in challenging cases with substantial loss of oral tissues, especially when treatment with fixed dental prostheses and/or dental implants is not possible. © 2014 by the American College of Prosthodontists.

Re-discovering periodontal butyric acid: New insights on an old metabolite.

PubMed

Cueno, Marni E; Ochiai, Kuniyasu

2016-05-01

The oral microbiome is composed of detrimental and beneficial microbial communities producing several microbial factors that could contribute to the development of the oral microbiome and, likewise, may lead to the development of host diseases. Metabolites, like short-chain fatty acids, are commonly produced by the oral microbiome and serve various functions. Among the periodontal short-chain fatty acids, butyric acid is mainly produced by periodontopathic bacteria and, attributable to the butyrate paradox, is postulated to exhibit a dual function depending on butyric acid concentration. A better understanding of the interconnecting networks that would influence butyric acid function in the oral cavity may shed a new light on the current existing knowledge and view regarding butyric acid.

This paper describes the results of a bi-level intervention, using a cognitive-behavioral theoretical approach, to improve the oral hygiene of older adults and the disabled in community-based low income senior housing. The bi-level pilot intervention consisted of an on-site tailored adapted motivational interviewing (AMI) session and two oral health fairs, supported by a resident campaign committee, to change community norms. All materials were available in English and Spanish. Participants completed a survey consisting of 12 domains that provided the basis for tailoring the AMI and shaping the campaigns. The domains were activities of daily living (ADLs), access to oral health information, oral hygiene status, dental knowledge, hygiene behaviors, importance of oral hygiene, self-efficacy/locus of control, diet, intentions, self-management worries/fears, perceived risk and dry mouth. Each participant received clinical assessments consisting of full-mouth plaque score (PS) and gingival index (GI) before the intervention and at three months. Twenty-seven residents with at least one tooth completed all phases of the study. The mean number of domains requiring attention was 4.5 (SD 1.6) with a range of one to seven. Mean baseline PS was 83% (SD 16%) which improved significantly to 58% (SD 31%); mean baseline GI was 1.15 (SD 0.61) and improved significantly to 0.49 (SD 0.46). This pilot study supports the feasibility and acceptability of a tailored oral hygiene intervention among older and disabled adults living in low income senior housing. Although a small sample, the study demonstrated significant improvements in both plaque and gingival scores three months after the bi-level intervention.

Aim: The aim of this study is to compare the effect of dental rehabilitation on oral health-related quality-of-life (OHRQoL) in children with special health care needs (CSHCN) and healthy children. Materials and methods: The prospective study's sample consisted of 213 parents of caries-affected children, who were aged 6 years or younger and were scheduled for dental rehabilitation under general anesthesia (DRGA). The parent-child dyads were recruited from three public hospitals in Jeddah between October 2014 and May 2016. They comprised healthy children (n = 133) and CSHCN (n = 80). Parents self-completed the early childhood oral health impact scale (ECOHIS) before and 1 month after DRGA. The parents also rated the overall oral health status of their children by answering a global question before and after DRGA. Results: At baseline, the CSHCN had significantly worse OHRQoL in most of the scale domains at 25.9 [standard deviation (SD) 11.3] and 19.9 (SD 10.3) respectively. The OHRQoL significantly improved in both groups postoperatively (p = 0.005, Wilcoxon rank-sum test). The effect size of the improvement in the CSHCN group (+1.8) was greater than that in the healthy group (+1.5) in all domains, except for the family impact and parental distress sections. Conclusion: The DRGA markedly improves OHRQoL in children aged 6 years or younger, and the improvement is even greater in CSHCN. Clinical significance: The substantial improvement in OHRQoL after DRGA highlights the importance of oral health care in young children, which should receive higher priority than it has been done to date.

Citicoline is an essential precursor in the synthesis of phosphatidylcholine, a key cell membrane phospholipid, and is known to have neuroprotective effects in acute ischemic stroke. The aim of this study was to determine the efficacy and safety of oral citicoline in Korean patients with acute ischemic stroke. A drug surveillance study was carried out in 4,191 patients with a diagnosis of acute ischemic stroke. Oral citicoline (500-4000 mg/day) was administered within less than 24 h after acute ischemic stroke in 3,736 patients (early group) and later than 24 h after acute ischemic stroke in 455 patients (late group) for at least 6 weeks. For efficacy assessment, primary outcomes were patients' scores obtained with a short form of the National Institutes of Health Stroke Scale (s-NIHSS), a short form of the Barthel Index of activities of daily living (s-BI) and a modified Rankin Scale (mRS) at enrollment, after 6 weeks and at the end of therapy for those patients with extended treatment. All adverse reactions were monitored during the study period for safety assessment. All measured outcomes, including s-NIHSS, s-BI and mRS, were improved after 6 weeks of therapy (P < 0.05). Further improvement was observed in 125 patients who continued citicoline therapy for more than 12 weeks when compared with those who ended therapy at week 6. Improvements were more significant in the higher dose group (> or = 2000 mg/day) (P < 0.001). s-BI scores showed no differences between the early and late groups at the end of therapy. Citicoline safety was excellent; 37 side effects were observed in 31 patients (0.73%). The most frequent findings were nervous system-related symptoms (8 of 37, 21.62%), followed by gastrointestinal symptoms (5 of 37, 13.5%). Oral citicoline improved neurological, functional and global outcomes in patients with acute ischemic stroke without significant safety concerns.

California has virtually no statewide dental public health infrastructure leaving the state without leadership, a surveillance program, an oral health plan, oral health promotion and disease prevention programs, and federal funding. Based on a literature review and interviews with 15 oral health officials nationally, the paper recommends hiring a state dental director with public health experience, developing a state oral health plan, and seeking federal and private funding to support an office of oral health.

Evidence is emerging that women's poor oral health and health practices during pregnancy are associated with poor oral health in their children and potentially an increased risk of pre-term or low-birth weight infants. The Midwifery Initiated Oral Health-Dental Service (MIOH-DS) trial is a three arm multicentre randomised controlled trial which will recruit women from three metropolitan hospitals aimed at improving women's oral health and service access and indirectly reducing perinatal morbidity. All three arms of the trial will deliver oral health promotion material, although a midwife oral assessment and referral to private/public/health fund dental services pathway (Intervention Group 1) and the midwife oral assessment and referral to local free public dental services pathway (Intervention Group 2) will be compared to the control group of oral health promotional material only. Midwives will undergo specific oral health education and competency testing to undertake this novel intervention. This efficacy trial will promote a new partnership between midwives and dentists focused on enhancing the oral health of women and their infants. Should the intervention be found effective, this intervention, with existing on-line educational program for midwives, can be easily transferred into practice for large metropolitan health services within and beyond Australia. Further cost-benefit analysis is proposed to inform national health policy. Australian New Zealand Clinical Trials Registry ACTRN12612001271897.

Aspirin is a commonly used medicine for primary and secondary prevention of cardiovascular diseases. It is an acidic medicine associated with gastric irritation and acid reflux, which in turn can lead to low oral pH levels. Therefore, it is important to understand the association between aspirin and oral pH levels in order to achieve an optimum oral health condition among patients who take aspirin on prescription. Out of 373 patients, 162 (44%) were males and 245 (66%) were on aspirin. 71% of aspirin taking patients and 29% of non-aspirin taking patients had oral pH less than 6.5 (P < 0.01). Aspirin showed a significant association with low oral pH levels (odds ratio = 1.91, 95% CI 1.23-2.99, P < 0.01). 78 patients were given antacids and followed up for 4 weeks, 63 of them (81%) showed an improvement in oral pH and the improvement was marked in the group who had oral pH between 5.5-6.0 compared to the group who had oral pH between 6.0-6.5 (P = 0.03). The results show that aspirin therapy is associated with low oral pH and administration of an antacid with aspirin helps to increase the oral pH level.

No comprehensive patient-centered and clinical evaluations of the functional effect of treatment with implant-supported single crowns (ISSC) have been reported previously. To investigate whether and how treatment with ISSC affects masticatory function and Oral Health-Related Quality of Life (OHRQoL) in subjects with tooth agenesis. In nine females and nine males (32 + or - 10 years) with agenesis treated with one to four ISSC (68% in the premolar region), the treatment effect and masticatory function were assessed. The evaluation was performed first after implant placement shortly before crown cementation, and again 1 month after cementation. It consisted of questionnaires [including Oral Health Impact Profile (OHIP-49)] and functional examination with plastic strips, the Dental Prescale Film and the Occluzer system, Xylitol color-changeable gum and slices of Granny Smith apple. The patients' satisfaction with treatment was high and they experienced a significant overall improvement in their OHRQoL (on average 13% reduction in the total OHIP scores). The cementation of the crowns was associated with a significant increase in the number of near occlusal tooth contacts, contact area, bite force, and masticatory ability and performance. Correspondingly, there was a significant, positive correlation between the number of tooth contacts and (1) occlusal contact area, (2) bite force, and (3) masticatory performance. Treatment with ISSCs in subjects with tooth agenesis significantly increased masticatory function subjectively and clinically as well as OHRQoL. However, as the functional parameters before replacement of the teeth corresponded to values in subjects with complete dentitions, the functional importance of the increase may be questioned.

All available direct oral anticoagulants (DOACs) are at least partially eliminated by the kidneys. These agents are increasingly being used as alternatives to warfarin for stroke prevention in patients with atrial fibrillation. The aim of this study was to identify changes in renal function and associated DOAC dosing implications in a multicenter cohort of atrial fibrillation patients switched from warfarin to DOAC treatment. We included all patients in the Michigan Anticoagulation Quality Improvement Initiative cohort who switched from warfarin to a DOAC with atrial fibrillation as their anticoagulant indication between 2009 and 2014, and who had at least two creatinine values. Compliance with FDA-recommended dosing based on renal function was assessed. Of the 189 patients switched from warfarin to a DOAC, 34 (18.0 %) had a baseline creatinine clearance <50 mL/min and 23 (12.2 %) experienced important fluctuations in renal function. Of these 23 patients, 6 (26.1 %) should have impacted the DOAC dosing, but only 1 patient actually received an appropriate dose adjustment. Additionally, 15 (7.9 %) of patients on DOACs had a dose change performed, but only one patient demonstrated a change in renal function to justify the dose adjustment. Most atrial fibrillation patients who switched from warfarin to a DOAC had stable renal function. However, the majority of patients who had a change in renal function did not receive the indicated dose change. As the use of DOACs expands, monitoring of renal function and appropriate dose adjustments are critical.

Global policy for improvement of oral health in the 21st century--implications to oral health research of World Health Assembly 2007, World Health Organization.

Petersen, Poul Erik

2009-02-01

The World Health Organization (WHO) Global Oral Health Programme has worked hard over the past 5 years to increase the awareness of oral health worldwide as oral health is important component of general health and quality of life. Meanwhile, oral disease is still a major public health problem in high income countries and the burden of oral disease is growing in many low- and middle income countries. In the World Oral Health Report 2003, the WHO Global Oral Health Programme formulated the policies and necessary actions to the continuous improvement of oral health. The strategy is that oral disease prevention and the promotion of oral health needs to be integrated with chronic disease prevention and general health promotion as the risks to health are linked. The World Health Assembly (WHA) and the Executive Board (EB) are supreme governance bodies of WHO and for the first time in 25 years oral health was subject to discussion by those bodies in 2007. At the EB120 and WHA60, the Member States agreed on an action plan for oral health and integrated disease prevention, thereby confirming the approach of the Oral Health Programme. The policy forms the basis for future development or adjustment of oral health programmes at national level. Clinical and public health research has shown that a number of individual, professional and community preventive measures are effective in preventing most oral diseases. However, advances in oral health science have not yet benefited the poor and disadvantaged populations worldwide. The major challenges of the future will be to translate knowledge and experiences in oral disease prevention and health promotion into action programmes. The WHO Global Oral Health Programme invites the international oral health research community to engage further in research capacity building in developing countries, and in strengthening the work so that research is recognized as the foundation of oral heath policy at global level.

The polymer/probucol co-milled mixtures were prepared to improve drug dissolution rate and oral bioavailability. Probucol, a BCS II drug, was co-milled together with Copovidone (Kollidon VA64, VA64), Soluplus, or MCC using the dry media-milling process with planetary ball-milling equipment. The properties of the milled mixtures including morphology, crystal form, vitro drug dissolution and in vivo oral bioavailability in rats were evaluated. Probucol existed as an amorphous in the matrix of the co-milled mixtures containing VA64, which helped to enhance drug dissolution. The ternary mixture composed of VA64, RH40, and probucol showed increased dissolution rates in both sink and non-sink conditions. It also had a higher oral bioavailability compared to the reference formulation. Dry-media milling of binary or ternary mixtures composed of drug, polymer and surfactant possibly have wide applications to improve dissolution rate and oral bioavailability of water-insoluble drugs.

Use of oral chemotherapy is expanding and offers advantages while posing unique safety challenges. ASCO and the Oncology Nursing Society jointly published safety standards for administering chemotherapy that offer a framework for improving oral chemotherapy practice at the University of Wisconsin Carbone Cancer Center. With the goal of improving safety, quality, and uniformity within our oral chemotherapy practice, we conducted a gap analysis comparing our practice against ASCO/Oncology Nursing Society guidelines. Areas for improvement were addressed by multidisciplinary workgroups that focused on education, workflows, and information technology. Recommendations and process changes included defining chemotherapy, standardizing patient and caregiver education, mandating the use of comprehensive electronic order sets, and standardizing documentation for dose modification. Revised processes allow pharmacists to review all orders for oral chemotherapy, and they support monitoring adherence and toxicity by using a library of scripted materials. Between August 2015 and January 2016, revised processes were implemented across the University of Wisconsin Carbone Cancer Center clinics. The following are key performance indicators: 92.5% of oral chemotherapy orders (n = 1,216) were initiated within comprehensive electronic order sets (N = 1,315), 89.2% compliance with informed consent was achieved, 14.7% of orders (n = 193) required an average of 4.4 minutes review time by the pharmacist, and 100% compliance with first-cycle monitoring of adherence and toxicity was achieved. We closed significant gaps between institutional practice and published standards for our oral chemotherapy practice and experienced steady improvement and sustainable performance in key metrics. We created an electronic definition of oral chemotherapies that allowed us to leverage our electronic health records. We believe our tools are broadly applicable.

The Michigan Oncology Quality Consortium (MOQC) is a continuous quality improvement collaborative seeking to improve oncology care in Michigan, including for patients taking oral chemotherapy. The aim of this study was to assess the relationship between patient activation, confidence to self-manage side effects, and adherence to oral oncolytics to inform future oncology care. A multicenter cross-sectional observational study was conducted using an online survey to examine patient activation (patient activation measure, PAM), health literacy, symptom burden (Edmonton Symptom Assessment System, ESAS), confidence to self-manage side effects (fatigue, nausea, and diarrhea), and adherence to oral oncolytics. Inclusion criteria were patients taking an oral oncolytic for at least 1 month. Bivariate analyses and logistic regression were performed to evaluate relationships between the variables. A total of 125 respondents, mean (SD) age 66.2 (13.6), 57.7% female, and 95.1% Caucasian completed the survey. The mean (SD) PAM score was 65.0 (18.0). Confidence to manage fatigue, nausea, and diarrhea was associated with higher activation, and confidence to self-manage fatigue and diarrhea were associated with higher health literacy. About 30% of participants reported some level of non-adherence to oral oncolytics, and those who experienced side effects (Fisher's exact test p = 0.033) and with shorter length of therapy (t test p = 0.027) were significantly more likely to be non-adherent. These findings show that there is room for improvement across practices involved with MOQC with regard to supporting patients taking oral oncolytics. Patients will need to improve their activation levels, and oncology clinics will need to create new workflows in order to enhance self-care management ability for patients taking oral oncolytics.

Radiation-induced xerostomia is a frequent late side effect after treatment for oral and oropharyngeal cancers. This may induce swallowing difficulties, compromised oral well-being, reduced nutrition intake, or speech deficiencies. Consequently, quality of life is often impaired for these patients. The purpose of this study was to investigate the possibility to mechanically stimulate residual saliva function by using tasteless and sugar-free chewing gum. It was hypothesized that tasteless and sugar-free chewing gum could immediately increase salivary flow and potentially improve oral well-being when used on a regular basis. From October to December 2014, 31 consecutive patients treated with primary radiotherapy (RT) and concomitant cisplatin (in locally advanced cases) for oral or oropharyngeal cancer consented to participate. All patients had finalized RT 2-8 months prior to participation and suffered from xerostomia. Samples of unstimulated and chewing gum-stimulated saliva were obtained at the entry into the study (Visit 1). For 2 weeks, patients used chewing gum on a regular basis whereupon saliva measurements were repeated to verify the changes (Visit 2). An abbreviated EORTC H&N35 questionnaire was completed for both visits. A small control group consisting of young and healthy individuals also tested the chewing gum. Twenty patients completed the study and an increase in saliva flow was observed for 14 patients. Before and after intervention with chewing gum, an increase in mean saliva output was seen between unstimulated and stimulated saliva for both Visit 1 and 2 (p = 0.008 and p = 0.05, respectively). No change in saliva output was seen in the control group. The chewing gum was able to stimulate saliva output that was seen at the beginning and at the end of the intervention. No improvement in baseline saliva was seen. Relevant changes in subjective measures of xerostomia were seen after 2 weeks of chewing the gum.

Predictors of Dysgeusia in Patients With Oropharyngeal Cancer Treated With Chemotherapy and Intensity Modulated Radiation Therapy

Sapir, Eli; Tao, Yebin; Feng, Felix

Objective(s): Dysgeusia is a significant factor reducing quality of life and worsening dysphagia in patients receiving chemoradiation therapy for head and neck cancer. The factors affecting dysgeusia severity are uncertain. We investigated the effects on patient-reported dysgeusia of doses to the oral cavity, salivary output (required to dissolve food particles), and patient-reported xerostomia. Methods and Materials: Seventy-three patients with stage III to IV oropharyngeal cancer (OPC) (N=73) receiving definitive intensity modulated radiation therapy concurrently with chemotherapy participated in a prospective, longitudinal study of quality of life (QOL), including assessment of patient-reported gustatory function by taste-related questions from the Head andmore » Neck QOL instrument (HNQOL) and the University of Washington Head and Neck-related QOL instrument (UWQOL), before therapy and periodically after treatment. At these intervals, patients also completed a validated xerostomia-specific questionnaire (XQ) and underwent unstimulated and stimulated major salivary gland flow rate measurements. Results: At 1, 3, 6, and 12 months after treatment, dysgeusia improved over time: severe dysgeusia was reported by 50%, 40%, 22%, and 23% of patients, respectively. Significant associations were found between patient-reported severe dysgeusia and radiation dose to the oral cavity (P=.005) and tongue (P=.019); normal tissue complication probability for severe dysgeusia at 3 months showed mean oral cavity D{sub 50} doses 53 Gy and 57 Gy in the HNQOL and WUQOL questionnaires, respectively, with curve slope (m) of 0.41. Measured salivary output was not statistically significantly correlated with severe taste dysfunction, whereas patient-reported XQ summary scores and xerostomia while eating scores were correlated with severe dysgeusia in the UWQOL tool (P=.04). Conclusions: Taste impairment is significantly correlated with mean radiation dose to the oral cavity. Patient-reported xerostomia, but not salivary output, was correlated with severe dysgeusia in 1 of the 2 QOL questionnaires. Reduction in oral cavity doses is likely to improve dysgeusia.« less

Meta-analysis: protein and energy supplementation in older people.

Protein and energy undernutrition is common in older people, and further deterioration may occur during illness. To assess whether oral protein and energy supplementation improves clinical and nutritional outcomes for older people in the hospital, in an institution, or in the community. Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, HealthStar, CINAHL, BIOSIS, and CAB abstracts. The authors included English- and non-English-language studies and hand-searched journals, contacted manufacturers, and sought information from trialists. The date of the most recent search of CENTRAL and MEDLINE is June 2005. Randomized and quasi-randomized controlled trials of oral protein and energy supplementation compared with placebo or control treatment in older people. Two reviewers independently assessed trials for inclusion, extracted data, and assessed trial quality. Differences were resolved by consensus. Fifty-five trials were included (n = 9187 randomly assigned participants). For patients in short-term care hospitals who were given oral supplements, evidence suggested fewer complications (Peto odds ratio, 0.72 [95% CI, 0.53 to 0.97]) and reduced mortality (Peto odds ratio, 0.66 [CI, 0.49 to 0.90]) for those undernourished at baseline. Few studies reported evidence that suggested any change in mortality, morbidity, or function for those given supplements at home. Ten trials reported gastrointestinal disturbances, such as nausea, vomiting, and diarrhea, with oral supplements. The quality of most studies, as reported, was poor, particularly for concealment of allocation and blinding of outcome assessors. Many studies were too small or the follow-up time was too short to detect a statistically significant change in clinical outcome. The clinical results are dominated by 1 very large recent trial in patients with stroke. Although this was a high-quality trial, few participants were undernourished at baseline. Oral nutritional supplements can improve nutritional status and seem to reduce mortality and complications for undernourished elderly patients in the hospital. Current evidence does not support routine supplementation for older people at home or for well-nourished older patients in any setting.

Dysphagia is a common problem in children with repaired oesophageal atresia (OA). Abnormalities in the oropharyngeal and oesophageal phase have hardly been studied. The aims of this study were to assess the prevalence of dysphagia in children with repaired OA and to identify and differentiate oral and pharyngeal dysphagia based on videofluoroscopic swallow study (VFSS) findings in a limited number of children in this cohort. Medical records of 111 patients, born between January 1996 and July 2013 and treated at the Radboudumc Amalia Children's Hospital, were retrospectively reviewed. The prevalence of dysphagia was determined by the objective and modified Functional Oral Intake Scale (FOIS) in four age groups. The first performed VFSS of 12 children was structurally assessed. The prevalence of dysphagia was 61 of 111 patients (55 %) in age group <1 year. In age group 1-4, 5-11 and 12-18 years, the prevalence of dysphagia decreased from 54 of 106 (51 %) patients to 11 of 64 (17 %) and 5 of 24 (21 %) patients. The 12 VFSS's reviews revealed oral dysphagia in 36 % and pharyngeal dysphagia in 75 %. This study highlights dysphagia as an important problem in different age groups of children with repaired OA. Furthermore, our study shows the presence of oropharyngeal dysphagia in this population. This study emphasizes the need to standardize the use of objective dysphagia scales, like the modified FOIS, to provide a careful follow-up of children with repaired OA. • Prevalence of dysphagia in children with repaired oesophageal atresia varies widely (ranges from 45 to 70 %) in literature. • Oral, pharyngeal and oesophageal dysphagia require different treatment approaches. What is New: • We determined dysphagia based on functional oral intake and provide an overview of change in dysphagia prevalence and severity over time in children with repaired OA. • Our study shows that dysphagia, including oropharyngeal dysphagia, is highly prevalent in young children with repaired OA and improves with time.

This study assessed the efficacy of oral care education among nursing home staff members to improve the oral health of residents. Nursing home support staff members (NHSSMs) in the study group received oral care education at baseline between a pretest and posttest. NHSSMs' oral care knowledge was measured using a 20-item knowledge test at baseline, posteducation, and at a 6-month follow-up. Residents' oral health was assessed at baseline and again at a 6-month follow-up using the Modified Plaque Index (PI) and Modified Gingival Index (GI). Among staff members who received the oral care education (n = 32), posttest knowledge statistically significantly increased from the pretest level (p < .05). Thirty-nine control residents of the nursing homes and 41 study residents participated. Among residents in the study group, PI decreased at 6 months compared to baseline (p < .05), but there was no statistically significant difference in their GI measurements between baseline and 6-month follow-up (p= .07). © 2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

2016-03-01

The natural product berberine (BBR) has become a potential drug in the treatment of diabetes, hyperlipidemia, and cancer. However, the oral delivery of BBR is challenged by its poor bioavailability. It is necessary to improve the oral bioavailability of BBR before it can be used in many clinical applications. Understanding the pharmacokinetic characteristics of BBR will enable the development of suitable formulas that have improved oral bioavailability. The key considerations for BBR are how to enhance the drug absorption and to avoid the intestinal first-pass effect. This review summarizes the pharmacological activities of BBR and analyzes the factors that lead to its poor oral bioavailability. In particular, the therapeutic potential of BBR in new indications from the aspect of oral bioavailability is discussed. In conclusion, BBR is a promising drug candidate for metabolic disorders and cancer but faces considerable challenges due to its poor oral bioavailability. Copyright © 2016 Elsevier B.V.

Soft tissue reconstruction of the oral cavity: a review of current options.

PubMed

Rigby, Matthew H; Taylor, S Mark

2013-08-01

This article provides an overview of the principles of soft tissue reconstruction of the oral cavity, and reviews the recent clinical outcomes for described options. For small defects of the oral cavity, healing by secondary intention and primary closure are both excellent options and may provide functionally superior results. In defects where a split-thickness skin graft is appropriate, acellular dermis may provide results that are at least as good at lower cost. Free flaps, particularly the radial forearm and the anterolateral thigh, have become the mainstays of oral cavity soft tissue reconstruction for larger defects. Recent clinical series suggest that relatively novel regional flaps provide a reasonable alternative to free flap reconstructions for moderate and some large soft tissue defects. Soft tissue reconstruction of the oral cavity is a complex task with significant functional implications. There are a large number of reconstructive options available. Systematic appraisal of the defect and options allows the reconstructive surgeon to optimize functional potential by choosing the most appropriate reconstructive option.

A Novel, Ecologically Relevant, Highly Preferred, and Non-invasive Means of Oral Substance Administration for Rodents

Prenatal stress and nutrition are well-known to alter a broad range of physiological systems, notably metabolic, endocrine and neurobehavioral function. Commonly used methods for oral administration of xenobiotics can, by acting as a stressor or altering normal nutrition intake, alter these physiological systems as well. Taken together, oral administration methods may unintentionally introduce confounding physiological effects that can mask or enhance toxicity of xenobiotics, particularly if they share biological targets. Consequently, it should be preferable to develop alternative methods without these potential confounds. The aim of this study was to determine the suitability of mealworms as an alternative treat-based method to deliver xenobiotics via the orogastric route. Accurate oral administration is contingent on motivation and preference; mice reliably preferred mealworms over wafer cookie treats. Further, ingestion of wafer cookies significantly increased mouse blood glucose levels, whereas unaltered mealworms produced no such change. Mealworms functioned effectively to orally administer glucose, as glucose-spiked mealworms produced a rise in blood glucose equivalent to the ingestion of the wafer cookie. Mealworms did not interfere with the physiological function of orally administered d-amphetamine, as both mealworm and oral gavage administered d-amphetamine showed similar alterations in locomotor behavior (mice did not fully consume d-amphetamine-dosed cookies and thus could not be compared). Collectively, the findings indicate that mealworms are a preferred and readily consumed treat, which importantly mimics environmental-relevant nutritional intake, and mealworms per se do not alter glucose metabolic pathways. Additionally, mealworms accurately delivered xenobiotics into blood circulation and did not interfere with the physiological function of administered xenobiotics. Thus mealworm-based oral administration may be a preferable and accurate route of xenobiotic administration that eliminates physiological alterations associated with other methods of delivery.

This systematic review aims to evaluate randomised controlled trials (RCTs) investigating the effect of vitamin D supplementation on endothelial function and inflammation in adults. An electronic search of published randomised controlled trials, using Cochrane, Pubmed and Medline databases was conducted, with the search terms related to vitamin D and endothelial function. Inclusion criteria were RCTs in adult humans with a measure of vitamin D status using serum/plasma 25(OH)D and studies which administered the intervention through the oral route. Among the 1107 studies retrieved, 29 studies met the full inclusion criteria for this systematic review. Overall, 8 studies reported significant improvements in the endothelial/inflammatory biomarkers/parameters measured. However, in 2 out of the 8 studies, improvements were reported at interim time points, but improvements were absent post-intervention. The remaining 21 trial studies did not show significant improvements in the markers of interest measured. Evidence from the studies included in this systematic review did not demonstrate that vitamin D supplementation in adults, results in an improvement in circulating inflammatory and endothelial function biomarkers/parameters. This systematic review does not therefore support the use of vitamin D supplementation as a therapeutic or preventative measure for CVD in this respect. Crown Copyright © 2017.

Oral communicative competence enables speakers of a language to interact effectively with each other. Oral communicative competence includes a wide semantic field since the oral expression is a way of expression for the thought and it provides feedback and develops by means of the linguistic function (Vygotsky, 1992; Piaget, 1983a, 1983b; Pinker,…

In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN) Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska's Tribal Health Organizations (THO) developed a new and diverse dental workforce model to address AI/AN oral health disparities. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA) Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

The range of indications for dental implants has broadened enormously owing to their predictability and the improvement of patient satisfaction in terms of stability, comfort, aesthetics and functionality. The aim of this article is to review those indications in patients with mental or physical disabilities as the difficulty to cope with oral hygiene often leads to teeth extraction, adding edentulousness to the impairments already present. Following that goal, available literature in Pubmed database, Scopus, Web of Knowledge and The Cochrane Library database about dental implants placement in these patients has been reviewed, assessing the variables of each study: number of patients, sex, average age, oral hygiene, parafunctional habits, impairment, bone quality, protocol of implant surgery, necessity of deep intravenous sedation or general anesthesia, follow-up period and number of failures. The comparison with studies involving other patient populations without mental or physical impediments did not show statistically significant differences in terms of the failure rate recorded. Although there is not much literature available, the results of this review seem to suggest that osseointegrated oral implants could be a therapeutic option in patients who suffer from any physical or psychological impairment. The success of an oral rehabilitation depends mainly on an adequate selection of the patients. Key words:Implants, disabled, sedation. PMID:24608221

Bacterial biofilm infections remain prevalent reasons for implant failure. Dental implant placement occurs in the oral environment, which harbors a plethora of biofilm-forming bacteria. Due to its trans-mucosal placement, part of the implant structure is exposed to oral cavity and there is no effective measure to prevent bacterial attachment to implant materials. Here, we demonstrated that UV treatment of titanium immediately prior to use (photofunctionalization) affects the ability of human polymicrobial oral biofilm communities to colonize in the presence of salivary and blood components. UV-treatment of machined titanium transformed the surface from hydrophobic to superhydrophilic. UV-treated surfaces exhibited a significant reduction in bacterial attachment as well as subsequent biofilm formation compared to untreated ones, even though overall bacterial viability was not affected. The function of reducing bacterial colonization was maintained on UV-treated titanium that had been stored in a liquid environment before use. Denaturing gradient gel-electrophoresis (DGGE) and DNA sequencing analyses revealed that while bacterial community profiles appeared different between UV-treated and untreated titanium in the initial attachment phase, this difference vanished as biofilm formation progressed. Our findings confirm that UV-photofunctionalization of titanium has a strong potential to improve outcome of implant placement by creating and maintaining antimicrobial surfaces. PMID:26210175

Functional iron deficiency (FID) is a major cause of persistent anemia in dialysis patients and also contributes to a suboptimal response to erythropoietin (Epo) administration. Vitamin C acts as an enzyme cofactor and enhances mobilization of the ferrous form of iron to transferrin thus increasing its bioavailability. High-dose intravenous vitamin C has been shown to decrease the Epo requirement and improve hemoglobin levels in previous studies. This study assessed the effect of low-dose oral vitamin C on possible reduction in Epo dose requirements in stable hemodialysis patients with FID. This prospective study included 22 stable hemodialysis patients with FID defined as transferrin saturation (T sat) <30 % and ferritin levels of >100 mcg/L with Epo requirement of ≥4000 U/HD session. Patients received oral vitamin C 250 mg daily for 3 months. Hemoglobin, iron and T sat levels were recorded monthly. No one received iron supplementation during the study period. There was a significant reduction in median Epo dose requirement in the 15 patients who completed the study, from 203.1 U/kg/week (95 % CI 188.4-270.6) to 172.8 U/kg/week (95 % CI 160.2-214.8), (P = 0.01). In the seven responders, there was 33 % reduction in Epo dose from their baseline. Despite adjustment of Epo dose, the mean hemoglobin level was significantly increased from 10.1 ± 0.6 to 10.7 ± 0.6 mg/dL (P = 0.03). No adverse effects of oral vitamin C were observed. Daily low-dose oral vitamin C supplementation reduced Epo dose requirements in hemodialysis patients with FID. Limitations of this study include a small sample size and the lack of measurements of vitamin C and oxalate levels. Despite concerns regarding oral vitamin C absorption in dialysis patients, this study indicates vitamin C was well tolerated by all participants without reported adverse effect.

A systematic review of methods to diagnose oral dryness and salivary gland function

PubMed Central

2012-01-01

Background The most advocated clinical method for diagnosing salivary dysfunction is to quantitate unstimulated and stimulated whole saliva (sialometry). Since there is an expected and wide variation in salivary flow rates among individuals, the assessment of dysfunction can be difficult. The aim of this systematic review is to evaluate the quality of the evidence for the efficacy of diagnostic methods used to identify oral dryness. Methods A literature search, with specific indexing terms and a hand search, was conducted for publications that described a method to diagnose oral dryness. The electronic databases of PubMed, Cochrane Library, and Web of Science were used as data sources. Four reviewers selected publications on the basis of predetermined inclusion and exclusion criteria. Data were extracted from the selected publications using a protocol. Original studies were interpreted with the aid of Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool. Results The database searches resulted in 224 titles and abstracts. Of these abstracts, 80 publications were judged to meet the inclusion criteria and read in full. A total of 18 original studies were judged relevant and interpreted for this review. In all studies, the results of the test method were compared to those of a reference method. Based on the interpretation (with the aid of the QUADAS tool) it can be reported that the patient selection criteria were not clearly described and the test or reference methods were not described in sufficient detail for it to be reproduced. None of the included studies reported information on uninterpretable/intermediate results nor data on observer or instrument variation. Seven of the studies presented their results as a percentage of correct diagnoses. Conclusions The evidence for the efficacy of clinical methods to assess oral dryness is sparse and it can be stated that improved standards for the reporting of diagnostic accuracy are needed in order to assure the methodological quality of studies. There is need for effective diagnostic criteria and functional tests in order to detect those individuals with oral dryness who may require oral treatment, such as alleviation of discomfort and/or prevention of diseases.

Early detection of a premalignant or cancerous oral lesion promises to improve the survival and the morbidity of patients suffering from these conditions. Cytological study of oral cells is a non-aggressive technique that is well accepted by the patient, and is therefore an attractive option for the early diagnosis of oral cancer, including epithelial atypia and squamous cell carcinoma. However its usage has been limited so far due to poor sensitivity and specificity in diagnosing oral malignancies. Lately it has re-emerged due to improved methods and it's application in oral precancer and cancer as a diagnostic and predictive method as well as for monitoring patients. Newer diagnostic techniques such as "brush biopsy" and molecular studies have been developed. Recent advances in cytological techniques and novel aspects of applications of scraped or exfoliative cytology for detecting these lesions and predicting their progression or recurrence are reviewed here.

The aim of this study was to compare the effectiveness of oral health counseling sessions with traditional oral hygiene education in orthodontic patients with fixed appliances. randomised control trial with experimental and control group. A group of 99 adolescents with fixed orthodontic appliances were randomly assigned to oral health counseling (experimental) or traditional health education (control) group. Subjects in the control group received verbal instructions and a demonstration of the modified Bass brushing technique on a model. The experimental group also received the verbal information with demonstration on the model and in addition a personalised 40-minutes counseling session on oral hygiene. Plaque Index (PI) and gingivitis (G) were recorded before, 1 and 6 months after the counseling session/traditional education. Oral health counseling and traditional education improved the oral hygiene of orthodontic patients. PI values were significantly lower after 6 months compared to the baseline in both groups, but the prevalence of gingival inflammation remained significantly lower only in the experimental group. Oral health counseling increased plaque removal efficacy and control of gingival inflammation. The efficiency of counseling and traditional education was similar. Counseling is a promising approach that warrants further attention in a variety of dental contexts.

Intracerebral hemorrhage (ICH) can cause direct brain injury at the insult site and indirect damage in remote brain areas. Although a protective effect of melatonin (ML) has been reported for ICH, its detailed mechanisms and effects on remote brain injury remain unclear. To clarify the mechanism of indirect neuroprotection after ICH, we first investigated whether ML improved motor function after ICH and then examined the underlying mechanisms. The ICH model rat was made by collagenase injection into the left globus pallidus, adjacent to the internal capsule. ML oral administration (15 mg/kg) for 7 days after ICH resulted in significant recovery of motor function. Retrograde labeling of the corticospinal tract by Fluoro-Gold revealed a significant increase in numbers of positive neurons in the cerebral cortex. Immunohistological analysis showed that ML treatment induced no difference in OX41-positive activated microglia/macrophage at day 1 (D1) but a significant reduction in 8-hydroxydeoxyguanosin-positive cells at D7. Neutral red assay revealed that ML significantly prevented H2 O2 -induced cell death in cultured oligodendrocytes and astrocytes but not in neurons. Electrophysiological response in the cerebral cortex area where the number of Fluoro-Gold-positive cells was increased was significantly improved in ML-treated rats. These data suggest that ML improves motor abilities after ICH by protecting oligodendrocytes and astrocytes in the vicinity of the lesion in the corticospinal tract from oxidative stress and causes enhanced electrical responsiveness in the cerebral cortex remote to the ICH pathology.

Cushing's syndrome requires glucocorticoid replacement following adrenalectomy. Based on a simplified glucocorticoid therapy scheme and the peri-operative observation, we investigated its efficacy and safety up to 6 months post-adrenalectomy in this cohort study. We found the adrenocorticotropic hormone (ACTH) levels were normal post-adrenalectomy, and sufficient to stimulate the recovery of the dystrophic adrenal cortex, thus exogenous supplemental ACTH might not be necessary. Patients were grouped by oral reception of either hydrocortisone or prednisone since day 2 post-adrenalectomy. Both groups had similar baseline responses to adrenalectomy, regarding the correction of hypertension (10/15 vs.12/19), hyperglycemia (6/11 vs. 7/10), and hypokalemia (12/12 vs. 11/11). Most patients lost weight (17/20 vs. 20/22). Both groups reported significant improvement in a subjective evaluation questionnaire. Hydrocortisone showed advantages over prednisone in improving liver function (7/8 vs. 2/7, p = 0.035), but also caused significant lower extremety edema ( p = 0.034). Both groups developed adrenal insufficiency (AI) during glucocorticoid withdrawal, with no significant difference regarding the incidence rate (7/20 vs. 10/22) or severity. Most AI symptoms were relieved by resuming the prior oral doses, while two severe cases were hospitalized. The withdrawal process may last longer time for hydrocortisone than prednisone. In conclusion, our data supports the use of both hydrocortisone and prednisone in the glucocorticoid replacement therapy post-adrenalectomy for patients of adrenal adenoma or Cushing's disease. Hydrocortisone showed advantages over prednisone in improving liver function, and prednisone exhibited significantly lower risk of edema.

Perspectives on the importance of postoperative ileus.

Sanfilippo, Filippo; Spoletini, Gabriele

Post-operative ileus (POI) is a common condition after surgery. Failure to restore adequate bowel function after surgery generates a series of complications and it is associated to patients frustration and discomfort, worsening their perioperative experience. Even mild POI can be source of anxiety and could be perceived as a drop out from the "straight-forward" pathway. Enhanced recovery programmes have emphasized the importance of early commencement of oral diet, avoiding the ancient dogmata of prolonged gastric decompression and fasting. These protocols with early oral feeding and mobilization have led to improved perioperative management and have decreased hospital length of stay, ameliorating patient's postoperative experience as well. Nonetheless, the incidence of POI is still high especially after major open abdominal surgery. In order to decrease the incidence of POI, minimally-invasive surgical approaches and minimization of surgical manipulation have been suggested. From a pharmacological perspective, a meta-analysis of pro-kinetics showed beneficial results with alvimopan, although its use has been limited by the augmented risk of myocardial infarction and the high costs. A more simple approach based on the postoperative use of chewing-gum has provided some benefits in restoring bowel function. From an anaesthesiological perspective, epidural anaesthesia/analgesia does not only reduce the postoperative consumption of systemic opioids but directly improve gastrointestinal function and should be considered where possible, at least for open surgical procedures. POI represents a common and debilitating complication that should be challenged with multi-disciplinary approach. Prospective research is warranted on this field and should focus also on patient s reported outcomes.

Orally disintegrating films (ODFs) can transport natural active compounds such as ethanol extract of propolis (EEP). This paper aimed to investigate the effect of lecithin on different gelatin and hydrolyzed collagen (HC) polymeric matrices with addition of EEP. ODFs were prepared by casting technique and were characterized (color parameters, water content, mechanical properties, microstructure, disintegration time (DT), infrared spectroscopy (FTIR), contact angle (CA), swelling degree and total phenolic content). The mechanical properties were influenced by HC. The microstructure demonstrated increased porosity and roughness in films with EEP, and the addition of lecithin resulted in an increase in the number of pores. Lecithin-gelatin and lecithin-EEP-gelatin interactions were observed by FTIR. The addition of HC and EEP reduced the DT and CA, and HC and lecithin reduced the swelling capacity. However, the swelling capacity was not affected by presence of EEP. The addition of lecithin to gelatin and HC ODFs may improve the incorporation and the oral transport of active compounds such as EEP. Copyright © 2016 Elsevier B.V. All rights reserved.

A case report of cholestatic jaundice in a 25 year old woman, who had had jaundice at age 4 years, and had taken Stediril (a combined oral contraceptive) for 1 month, implicates either the pill or a possibly hereditary hyperlipidemia. The jaundice developed in 2 weeks with vomiting, epigastric pain, anorexia, then discolored urine and feces, and intense pruritus. On hospitalization the patient had moderate bilirubinemia (56 mg/1), low alkaline phosphatase (13 U.K.) and slightly high serum glutamate pyruvate transaminase (270 U.W.). There were elevated serum cholesterol (3 gm/1), triglycerides (2.05 gm/1), total lipids (10.6 gm/1), and a definitely increased pre-beta lipoprotein, suggesting hyperlipidemia type IV (Frederickson classification). Liver biopsy showed fibrosis of the portal spaces lymphocytic infiltration, canalicular and intrahepatocytic thrombi. On laparoscopy the liver had a regular lower border, normal volume color and surface. Albumin, prothrombin and flocculation tests were normal. The patient's jaundice lasted about 1 month, then liver function slowly improved, although pruritus remained intense. Probably this jaundice was due to oral contraceptives, in a patient predisposed either by jaundice in childhood or endogenous hyperlipidemia.

Purpose: Rare spontaneous remissions from age-related macular degeneration (AMD) suggest the human retina has large regenerative capacity, even in advanced age. We present examples of robust improvement of retinal structure and function using an OTC oral resveratrol (RV) based nutritional supplement called Longevinex® or L/RV (circa 2004, Resveratrol Partners, LLC, Las Vegas, NV, USA). RV, a polyphenolic phytoalexin caloric-restriction mimic, induces hormesis at low doses with widespread beneficial effects on systemic health. RV alone inhibits neovascularization in the murine retina. Thus far, published evidence includes L/RV mitigation of experimentally induced murine cardiovascular reperfusion injury, amelioration of human atherosclerosis serum biomarkers in a human Japanese randomized placebo controlled trial, modulation of micro RNA 20b and 539 that control hypoxia-inducing-factor (HIF-1) and vascular endothelial growth factor (VEGF) genes in the murine heart (RV inhibited micro RNA20b 189-fold, L/RV 1366-fold). Little is known about the effects of L/RV on human ocular pathology. Methods: Absent FDA IRB approval, but with permission from our Chief of Staff and medical center IRB, L/RV is reserved for AMD patients, on a case-by-case compassionate care basis. Patients include those who progress on AREDS II type supplements, refuse intra-vitreal anti-VEGF injections or fail to respond to Lucentis®, Avastin® or Eylea®. Patients are clinically followed traditionally as well as with multi-spectral retinal imaging, visual acuity, contrast sensitivity, cone glare recovery and macular visual fields. Three cases are presented. Results: Observed dramatic short-term anti-VEGF type effect including anatomic restoration of retinal structure with a suggestion of improvement in choroidal blood flow by near IR multispectral imaging. The visual function improvement mirrors the effect seen anatomically. The effect is bilateral with the added benefit of better RPE function. Effects have lasted for one year or longer when taken daily, at which point one patient required initiation of anti-VEGF agents. Unanticipated systemic benefits were observed. Conclusions: Preliminary observations support previous publications in animals and humans. Restoration of structure and visual function in octogenarians with daily oral consumption of L/RV is documented. Applications include failure on AREDS II supplements, refusing or failing conventional anti-VEGF therapy, adjunct therapy to improve RPE function, and compassionate use in medically underserved or economically depressed third-world countries.
