We report a case series of asymptomatic infections affecting failed corneal grafts in patients referred for repeat penetrating keratoplasty (PK). In this retrospective, noncomparative, interventional case series, we reviewed the medical records of all repeat PK procedures performed at Villa Serena-Villa Igea private Hospitals (Forlì, Italy) between January 2011 and March 2016. Specifically, preoperative and postoperative slit-lamp examinations, and the results of histological and bacteriological examinations, were noted. Fifty-three repeat PKs were performed in the study period. All patients were referred because of long-standing graft decompensation with stromal scars or surface irregularities, thus unsuitable for endothelial keratoplasty. None was referred because of presumed infection. Histological examination of the explanted buttons showed the presence of microorganisms of various types in 7 eyes. Cultures were positive in 4 of these cases and in one additional case Staphylococcus aureus was grown in culture, but was not seen in the histology specimen. None of the patients presented with unusual pain, tearing, or discomfort. Preoperative abnormal clinical findings included epithelial defect (n = 6), focal whitening of corneal stroma (n = 5), crystalline keratopathy (n = 1), and an elevated pigmented lesion (n = 1). After repeat PK, recurrence of the infection was seen in 5 of 7 (71%) cases, 2 of which required a third PK procedure. Apparently quiet eyes with failed PK can harbor slow-growing asymptomatic infection. An epithelial defect in a failed PK graft should raise suspicion of infection. Routine cultures and histological examination of the excised corneal buttons are instrumental in the diagnosis of these infections and can guide further treatment.

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in childhood. The psychostimulant methylphenidate is the most frequently used medication to treat it. Several studies have investigated the benefits of methylphenidate, showing possible favourable effects on ADHD symptoms, but the true magnitude of the effect is unknown. Concerning adverse events associated with the treatment, our systematic review of randomised clinical trials (RCTs) demonstrated no increase in serious adverse events, but a high proportion of participants suffered a range of non-serious adverse events. To assess the adverse events associated with methylphenidate treatment for children and adolescents with ADHD in non-randomised studies. In January 2016, we searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, 12 other databases and two trials registers. We also checked reference lists and contacted authors and pharmaceutical companies to identify additional studies. We included non-randomised study designs. These comprised comparative and non-comparative cohort studies, patient-control studies, patient reports/series and cross-sectional studies of methylphenidate administered at any dosage or formulation. We also included methylphenidate groups from RCTs assessing methylphenidate versus other interventions for ADHD as well as data from follow-up periods in RCTs. Participants had to have an ADHD diagnosis (from the 3rd to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders or the 9th or 10th edition of theInternational Classification of Diseases, with or without comorbid diagnoses. We required that at least 75% of participants had a normal intellectual capacity (intelligence quotient of more than 70 points) and were aged below 20 years. We excluded studies that used another ADHD drug as a co-intervention. Fourteen review authors selected studies independently. Two review authors assessed risk of bias independently using the ROBINS-I tool for assessing risk of bias in non-randomised studies of interventions. All review authors extracted data. We defined serious adverse events according to the International Committee of Harmonization as any lethal, life-threatening or life-changing event. We considered all other adverse events to be non-serious adverse events and conducted meta-analyses of data from comparative studies. We calculated meta-analytic estimates of prevalence from non-comparative cohorts studies and synthesised data from patient reports/series qualitatively. We investigated heterogeneity by conducting subgroup analyses, and we also conducted sensitivity analyses. We included a total of 260 studies: 7 comparative cohort studies, 6 of which compared 968 patients who were exposed to methylphenidate to 166 controls, and 1 which assessed 1224 patients that were exposed or not exposed to methylphenidate during different time periods; 4 patient-control studies (53,192 exposed to methylphenidate and 19,906 controls); 177 non-comparative cohort studies (2,207,751 participants); 2 cross-sectional studies (96 participants) and 70 patient reports/series (206 participants). Participants' ages ranged from 3 years to 20 years. Risk of bias in the included comparative studies ranged from moderate to critical, with most studies showing critical risk of bias. We evaluated all non-comparative studies at critical risk of bias. The GRADE quality rating of the evidence was very low.Primary outcomesIn the comparative studies, methylphenidate increased the risk ratio (RR) of serious adverse events (RR 1.36, 95% confidence interval (CI) 1.17 to 1.57; 2 studies, 72,005 participants); any psychotic disorder (RR 1.36, 95% CI 1.17 to 1.57; 1 study, 71,771 participants); and arrhythmia (RR 1.61, 95% CI 1.48 to 1.74; 1 study, 1224 participants) compared to no intervention.In the non-comparative cohort studies, the proportion of participants on methylphenidate experiencing any serious adverse event was 1.20% (95% CI 0.70% to 2.00%; 50 studies, 162,422 participants). Withdrawal from methylphenidate due to any serious adverse events occurred in 1.20% (95% CI 0.60% to 2.30%; 7 studies, 1173 participants) and adverse events of unknown severity led to withdrawal in 7.30% of participants (95% CI 5.30% to 10.0%; 22 studies, 3708 participants).Secondary outcomesIn the comparative studies, methylphenidate, compared to no intervention, increased the RR of insomnia and sleep problems (RR 2.58, 95% CI 1.24 to 5.34; 3 studies, 425 participants) and decreased appetite (RR 15.06, 95% CI 2.12 to 106.83; 1 study, 335 participants).With non-comparative cohort studies, the proportion of participants on methylphenidate with any non-serious adverse events was 51.2% (95% CI 41.2% to 61.1%; 49 studies, 13,978 participants). These included difficulty falling asleep, 17.9% (95% CI 14.7% to 21.6%; 82 studies, 11,507 participants); headache, 14.4% (95% CI 11.3% to 18.3%; 90 studies, 13,469 participants); abdominal pain, 10.7% (95% CI 8.60% to 13.3%; 79 studies, 11,750 participants); and decreased appetite, 31.1% (95% CI 26.5% to 36.2%; 84 studies, 11,594 participants). Withdrawal of methylphenidate due to non-serious adverse events occurred in 6.20% (95% CI 4.80% to 7.90%; 37 studies, 7142 participants), and 16.2% were withdrawn for unknown reasons (95% CI 13.0% to 19.9%; 57 studies, 8340 participants). Our findings suggest that methylphenidate may be associated with a number of serious adverse events as well as a large number of non-serious adverse events in children and adolescents, which often lead to withdrawal of methylphenidate. Our certainty in the evidence is very low, and accordingly, it is not possible to accurately estimate the actual risk of adverse events. It might be higher than reported here.Given the possible association between methylphenidate and the adverse events identified, it may be important to identify people who are most susceptible to adverse events. To do this we must undertake large-scale, high-quality RCTs, along with studies aimed at identifying responders and non-responders.

To evaluate the outcome of scleral patch grafts in a series of patients undergoing management for uveal and ocular surface tumors. Case series. Ten patients underwent scleral patch grafting. Five patients had uveal melanoma with extrascleral extension, 2 patients had scleromalacia secondary to plaque radiotherapy for uveal melanoma, 2 patients had suspicious uveoscleral nevi, and 1 patient had invasive conjunctival squamous cell carcinoma with scleral necrosis. Retrospective, interventional, noncomparative chart review of patients undergoing treatment for ocular tumors followed by scleral grafts in a tertiary eye care center in the United States between September 2003 and January 2011. Sclera was reconstructed with allogenic scleral grafts. Clinical observations were performed after grafting. Structural integrity, appearance, and stability of the grafts. Ten patients were reviewed. All melanoma cases received plaque radiotherapy with palladium 103. The cases with nevi and squamous cell carcinoma underwent local resection with cryotherapy as primary treatment. In 8 cases, scleral grafting was performed as part of the initial surgery. In all of these cases, satisfactory anatomic and functional outcomes were achieved. In 2 cases with scleromalacia secondary to radiotherapy for uveal melanoma, grafts were placed several years after the initial treatment. In these 2 cases, one showed signs of graft retraction, whereas another showed graft thinning. No patients experienced graft infection, rejection, or tumor recurrence. In this series, scleral grafts were well accepted when placed as part of the primary tumor management despite synchronous radiotherapy, scleral resection, or cryotherapy. Grafting was less successful when performed as a late procedure for radiation-induced scleromalacia.

To evaluate the effect of intravitreal bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA) injections on visual acuity and foveal retinal thickness in patients with central retinal vein occlusion (CRVO). In this prospective, noncomparative, consecutive, interventional case series, 46 patients received repeated intravitreal injections (1.25 mg) of bevacizumab. Main outcome measures were visual acuity (Snellen and ETDRS charts) and optical coherence tomography measurements in a 6-month follow-up period. Mean visual acuity improved from 20/250 at baseline to 20/80 at the 6-month follow-up (P < 0.001). ETDRS chart findings revealed a mean letter gain +/-SD from baseline to 6 months of 13.9 +/- 14.4 letters. Mean central retinal thickness +/-SD decreased from 535 +/- 148 microm at baseline to 323 +/- 116 microm at the 6-month follow-up. Ischemic CRVO was associated with significantly lower visual acuity than nonischemic CRVO (P < 0.001). However, visual acuity gain was similar in both groups. Independent of duration of symptoms, CRVO was associated with a similar gain in visual acuity. Intravitreal injection of bevacizumab appears to be a new treatment option for patients with macular edema secondary to CRVO.

Rivaroxaban in patients with atrial fibrillation: from ROCKET AF to everyday practice.

Registries and non-interventional studies offer relevant and complementary information to clinical trials, since they have a high external validity. Areas covered: The information regarding the efficacy and safety of rivaroxaban compared with warfarin, or rivaroxaban alone in clinical practice was reviewed in this manuscript. For this purpose, a search on MEDLINE and EMBASE databases was performed. The MEDLINE and EMBASE search included both medical subject headings (MeSH) and keywords including: atrial fibrillation (AF) OR warfarin OR clinical practice OR ROCKET AF AND rivaroxaban. Case reports were not considered. Expert commentary: In ROCKET AF, rivaroxaban was at least as effective as warfarin for the prevention of stroke in patients with nonvalvular AF at high risk of stroke, but, importantly, with a lesser risk of intracranial, critical and fatal bleedings. A number of observational comparative and non-comparative studies, with more than 60,000 patients included treated with rivaroxaban, have analyzed the efficacy and safety of rivaroxaban in real-life patients with AF in different clinical settings. These studies have shown that in clinical practice, rates of stroke and major bleeding were consistently lower than those reported in ROCKET AF, likely due to the lower thromboembolic and bleeding risk observed in these patients.

To evaluate the results of sutureless amniotic membrane (AM) transplantation using fibrin glue for reconstructing corneal surfaces with partial limbal stem cell deficiency (LSCD). Retrospective noncomparative interventional case series. Eleven eyes of nine patients that had LSCD with 120 degrees to almost 360 degrees of limbal involvement underwent superficial keratectomy to remove the conjunctivalized pannus followed by AM transplantation using fibrin glue. Additional sutureless AM patch (ProKera; Bio-Tissue, Inc, Miami, Florida, USA) was used in seven patients, and mitomycin C was applied on the cornea in four eyes and during fornix reconstruction in seven eyes. The surgery was repeated in three eyes for residual pannus. During a mean follow-up of 14.2 +/- 7.7 months (range, six to 26 months), all eyes maintained a smooth and stable corneal epithelial surface without recurrent erosion or persistent epithelial defect, and showed less stromal cloudiness and vascularization. Best-corrected visual acuity improved in nine eyes (81.8%). Corneal epithelialization proceeded by epithelial growth over AM (n = 4), accompanied by dissolution of AM (n = 4) or a combination of both (n = 3). No complication was noted regarding initial or repeated uses of fibrin glue. AM transplantation using fibrin glue appears to be a safe and effective method of restoring a stable corneal epithelium for cases with partial LSCD. This approach avoids the need of transplanting limbal epithelial stem cells.

To report the efficacy of a full-thickness skin graft (FTSG) for the reconstruction of a contracted eye socket. A retrospective, non-comparative, interventional case series. This was a retrospective review of patients with a contracted eye socket who underwent socket reconstruction using a post-auricular FTSG from 2001 to 2011 at the National Taiwan University Hospital. The postoperative results including prosthetic fitting, the cosmetic result, and eyelid function were assessed. There were 11 male and 15 female patients, with a mean age of 52.3 ± 15.6 years (range 21 to 76). The duration of the socket contracture varied from three months to three years (average 7.4 ± 8.1 months). The severity of the socket contracture ranged from grade 2 to grade 4, based on Tawfik's classification. The mean follow-up time was 35.7 ± 9.6 months. After socket reconstruction, using a post-auricular FTSG, 96% of the cases (25 of 26) demonstrated a successful prosthetic fitting and a satisfactory cosmetic outcome. Both good eyelid function and a stable fornix depth were maintained during the follow-up time. One case received a second socket reconstruction three months after the first operation, using a FTSG, because of an inadequate lateral fornix. The final result was satisfactory. There were no serious complications, but a granuloma formed in one case, and there was prolonged discharge in one case. The reconstruction of a contracted eye socket using a post-auricular FTSG is an effective method with a high success rate, which causes less discomfort to donor sites and results in few complications.

Purpose: To elucidate the manifestations of ocular injuries in the colored corn starch dust explosion at a Taiwan water park. Methods: This is a retrospective, non-comparative, consecutive-interventional case series. Fifty explosion-injury patients on 27 June 2015 treated at Chang-Gung Memorial Hospital, Linkou, were included. Thorough ophthalmic examinations were based on emergent triage and consecutive ophthalmological consultations. Multiple ocular and systemic parameters were assessed. Results: Of the 100 eyes in the 50 cases reviewed, 22 cases were male and 28 cases were female. The mean age was 22.08 ± 4.64 years, and the mean burn total body surface area (TBSA) of patients was 45.92 ± 20.30%. Of the 50 patients, 20 had Grade 1 ocular burns, and the others were without ocular involvement. Two of the 20 cases that presented Grade 1 ocular burns died within 1 month due to other systemic complications. The most common ocular manifestations among those with ocular injuries included periocular swelling (75%), followed by conjunctival chemosis (65%), conjunctival hyperemia (50%), singed eyelashes (20%), cornea epithelial defects (10%), and punctate keratopathy (5%). It is worth mentioning that one patient developed herpes simplex keratitis due to stress 3 weeks after being burned. Half of the 50 patients had facial burns. Specifically, the patients with a greater TBSA presented more significant ocular-burn manifestations than those patients with lower TBSA. Conclusion: Prompt ophthalmologic consultations are particularly necessary for mass burn-casualty patients with facial burns, inhalation injuries, and greater TBSA. The inspection and control of all ignition sources and the manipulation of dust with low concentrations and in an open space are crucial factors to prevent future dust explosions. PMID:29018726

Ocular toxoplasmosis is a potentially blinding cause of posterior uveitis. Retinal detachment is rare complication of ocular toxoplasmosis. To report the clinical course and prognosis of retinal breaks and detachments occurring in patients with ocular toxoplasmosis. This study was a retrospective, non-comparative case series of five patients with ocular toxoplasmosis who had consulted us with retinal detachment. All of the participants had retinal detachment after severe and treatment resistant toxoplasmic retinochoroiditis, leaving one of them with decreased visual acuity to light perception in spite of treatment and final visual acuity was 20/100 or better in four patients. The functional prognosis for the patients with retinal detachment was poor. Careful retinal examination in ocular toxoplasmosis is warranted, especially in patients with severe intraocular inflammation.

Objectives: To examine the economic evidence for interventions aimed at family carers of stroke patients. Data sources: Searches (limited to those published in English since 1990) were performed in key databases along with hand searches of relevant papers. Review methods: Papers were restricted to studies including any economic data (broadly defined) for any intervention targeting carers explicitly or explicitly referring to a carer element, beyond involving carers in the care or intervention for patients (i.e. more than just carers being invited to observe an intervention targeted at the patient). Two reviewers independently screened full papers and extracted data using guidance from the National Institute for Health and Care Excellence, and quality assessment using the Newcastle-Ottawa Quality Assessment Scale (cohort studies), the Delphi list (randomised controlled trials) and guidelines on economic quality from the British Medical Journal. Data were reviewed descriptively as meta analyses were inappropriate due to non-comparability of studies. Results: Ten papers were included in the review. These were heterogeneous in their design, intervention and economic analyses making comparison difficult. Only three of the ten papers included economic evaluations. All three reported that the intervention was less costly and had better or equivalent outcomes than the control comparator although two of these were based on the same intervention using the same dataset. Conclusion: There is some limited evidence that interventions for family carers of stroke patients are effective and cost effective. However, due to variation in the types of interventions examined, little can be concluded regarding implications for clinical practice. PMID:25758943

The purpose of this study was to investigate the hitherto undescribed effects of botulinum toxin A injected into the lacrimal gland in patients with functional epiphora. A prospective non-comparative interventional case series study was designed to include patients with functional epiphora who presented to the Oculoplastic unit at the Wolverhampton and Midland Counties Eye Infirmary. Botulinum toxin A (2.5-5 units) was injected into the palpebral lobe of the lacrimal gland on the worst affected side via a transconjunctival approach under topical anaesthesia. Patients underwent a Schirmer test and provided a subjective evaluation of their epiphora symptoms, indoors and outdoors, at baseline and at 1, 4 and 13 weeks after injection. The mean score for symptoms indoors and outdoors was calculated. Fourteen patients agreed to take part in the study. Subjective epiphora scores improved in 8 out of the 11 patients (72.7%) who completed 13 weeks of follow-up. Schirmer test results showed objective reduction in tearing from baseline but did not strongly correlate with the subjective epiphora scores. Transient mild ptosis and diplopia were experienced by two patients. The results from this small pilot study are encouraging, although larger, controlled trials are needed to assess the optimal dose of BTX-A, its long-term efficacy and safety, and the role of multiple injections.

To introduce a new simple surgical approach with high-frequency radio-wave electrosurgery to reduce conjunctivochalasis (CCh). Prospective, noncomparative, interventional case series analysis. Twelve patients (20 eyes) with CCh were recruited from the outpatient service of the Department of Ophthalmology, Kangbuk Samsung Hospital, Seoul, Korea. On the inferior bulbar conjunctiva, subconjunctival coagulation was performed with a fine-needle electrode using a high-frequency radio-wave electrosurgical unit (Ellman Surgitron; Ellman International, Inc., Hewlett, NY) in coagulation mode. Conjunctivochalasis grade; epiphora and dry eye symptoms (the Ocular Surface Disease Index [OSDI]; Allergan Inc., Irvine, CA, holds the copyright); and intraoperative and postoperative complications. Eighteen eyes (90%) recovered a smooth, wet, and noninflamed conjunctival surface within 1 month and remained stable for a follow-up period of 3 months. At 3 months postoperatively, 18 eyes (90%) had grade 0 CCh. There was a statistically significant decrease of the OSDI score at 3 months postoperatively (P < 0.001). A surgical approach with high-frequency radio-wave electrosurgery produced a significant reduction in CCh and an improvement in symptoms. Radio-wave surgical techniques represent a favorable alternative to surgical treatment of CCh. The author(s) have no proprietary or commercial interest in any materials discussed in this article.

To report rates of recurrence and complications of localized ocular surface squamous neoplasia treated with 5-fluorouracil or mitomycin C as adjunctive treatment to surgical excision. Long-term follow up of two prospective, non-comparative interventional case series. One hundred fifty-three eyes with histologically confirmed localized, non-invasive ocular surface squamous neoplasia. 89 eyes were treated with adjuvant 5-fluorouracil and 64 eyes were treated with adjuvant mitomycin C. Following surgical excision±cryotherapy patients received topical 5-fluorouracil 1% four times daily for two weeks or topical mitomycin C 0.04% four times daily for two to three 1-week cycles. Ocular surface squamous neoplasia recurrence, complications of therapy and compliance. Median follow up was 33.6 (range 12-84) months and 57.9 (range 12-160) months in 5-fluorouracil and mitomycin C groups, respectively. There was one recurrence in the 5-fluorouracil group and no recurrences in the mitomycin C group. Side-effects occurred in 69% of 5-fluorouracil patients and 41% of mitomycin C patients. Five patients (6%) required intervention for treatment-related side-effects in the 5-fluorouracil group versus 11 (17%) in the mitomycin C group. No vision-threatening complications were noted. Long-term recurrence of localised ocular surface squamous neoplasia is rare when topical 5-fluorouracil or mitomycin C are used as adjunctive treatment to surgical excision. While side-effects are common, the majority are transient and rarely limit compliance. © 2013 Royal Australian and New Zealand College of Ophthalmologists.

The purpose of this study was to describe the incidence, clinical characteristics, and outcome of eccentric macular holes presenting after vitrectomy and internal limiting membrane (ILM) peeling for the treatment of macular pathology and discuss the pathogenesis of holes formation. A retrospective, noncomparative, interventional case-series study of five patients who developed eccentric macular holes postoperatively following vitrectomy in 198 consecutive patients who underwent ILM peeling for idiopathic macular hole and epiretinal membrane formation between 2008 and 2015. Five patients (2.5 %) developed full-thickness eccentric macular holes postoperatively. Three patients presented with a single eccentric macular hole, one patient had an eccentric hole after a failed idiopathic macular hole surgery and one patient developed four eccentric macular holes. The mean diameter of the holes was 584 μm (range 206-1317 μm) and the average time of holes formation after vitrectomy was 27.7 weeks (range 1-140 weeks). Postoperative best-corrected visual acuity ranged from "counting fingers" to 20/25. The eyes with the holes distant from the fovea had the best final visual acuity. No further intervention was attempted and no complications occurred. The mean follow-up time was 26.8 months. The postoperative macular holes after vitrectomy and ILM peeling were variable in number, size, and time of appearance but remained stable and were not associated with any complications. The pathogenesis of macular holes is most consistent with contraction of the residual ILM or secondary epimacular proliferation probably stimulated by ILM peeling.

This study analyzes the results of intraocular pressure (IOP) reduction by contact diode cycloablation (cyclodiode) in cases of refractory glaucoma after penetrating keratoplasty. Retrospective noncomparative, interventional case series. Twenty-eight eyes in 28 patients attending the Moorfields Eye Hospital. Cyclodiode (40 applications x 1.5 W x 1.5 seconds over 270-300 degrees ) was used to control the IOP in refractory glaucoma after penetrating keratoplasty. Postoperative IOP, graft status, visual acuity, and number of antiglaucoma medications were recorded after cyclodiode treatment. Cyclodiode resulted in a reduction of IOP from a median of 33 mmHg (interquartile range [28, 40.5]) to a median of 15 mmHg (interquartile range [12, 20.5]). Most patients had a significant lowering in IOP with a median reduction of 16 mmHg (interquartile range [12, 25]; P < 0.0001). IOPs of 6 to 21 mmHg were achieved in 22 patients (79%). Sixteen patients (57%) required more than one treatment with cyclodiode to control the IOP, with three patients (11%) requiring three treatments and two patients (7%) requiring four treatments. Visual acuity improved (> two Snellen lines of acuity) in three patients (11%) and remained the same (+/- one Snellen line) in 17 patients (61%). The mean number of antiglaucoma medications before cycloablation was 2.6 and was 1.8 after treatment (P < 0.001). Of the 19 patients (68%) with originally clear grafts, three grafts (16%) developed opacification. One patient (4%), with a history of nanophthalmos and recurrent uveal effusion, had delayed hypotony (IOP < 6 mmHg) occurring 46 months after the diode treatment. All patients had at least 6 months follow-up. These patients have often undergone multiple previous complicated ocular interventions and are often not suitable for filtration surgery. Reduction of IOP with maintenance of visual acuity and a good safety profile was achieved in most patients in this study but may require multiple treatments. We propose cyclodiode as an effective treatment for many patients in the management of refractory glaucoma after penetrating keratoplasty.

We reviewed 40 consecutive charts of adult patients with the clinical diagnosis of Parinaud syndrome at the Royal Adelaide Hospital Department of Ophthalmology in Adelaide, South Australia, between 1991 and 2016. Charts were reviewed for the following: (1) demographic information, (2) clinical presentation, (3) neuro-ophthalmology signs, (4) aetiology of Parinaud syndrome, and (5) management. Examination findings were collected at initial evaluation, throughout the course of follow-up, and at last follow-up. All the cases were assessed by one of the authors (JLC). The commonest presenting symptoms were diplopia (67.5%) and blurred vision (25%) followed by visual field defect (12.5%), ataxia (7.5%) and manifest squint (7.5%). The commonest presenting signs were vertical gaze palsy (100%), convergence-retraction nystagmus (87.5%) and light-near dissociation (65.0%). Only 65.0% patients had the classical triad of vertical gaze palsy, convergence-retraction nystagmus and light-near dissociation. Midbrain pathologies including haemorrhage (30.0%), infarction (20.0%) and tumour (15.0%) were the commonest aetiology. Pineal region tumours accounted for 30.0% of presentations. Symptoms were managed conservatively in 45% of cases with temporary occlusion, prisms or refractive correction, and observation in 42.5% of cases. Surgical intervention for refractory diplopia was required in 12.5% of cases, of which 80% reported symptom resolution following surgery. Our series highlights the variable clinical presentation of Parinaud syndrome. The classic triad of conjugate upgaze paralysis, convergence-retraction nystagmus and light-near dissociation was only present in 65% of cases. Pineal neoplasms remain an important aetiological consideration; however, primary midbrain pathology including infarction and haemorrhage constituted the majority of our cases and should be considered in all patients. Conservative management approaches for ocular symptoms are sufficient in most cases although surgical treatment of upgaze palsy can be a useful option in refractory cases. © 2016 Acta Ophthalmologica Scandinavica Foundation.

To report the incidence of orbital cellulitis after orbital blowout fracture. Retrospective, noncomparative, interventional case series. All patients with orbital cellulitis and a history of recent orbital fracture. A medical record review of clinical history, imaging studies, and surgical and treatment outcome was performed. Resolution of orbital cellulitis and surgical and imaging findings. Four patients (3 male; mean age, 30 years [range, 4.5-58]) were treated for orbital cellulitis complicating orbital fracture. All patients had evidence of paranasal sinusitis before or after the orbital injury, and 2 also reported forceful nose blowing after sustaining orbital trauma. Although 3 patients received prophylactic oral antibiotics after the fracture, this failed to prevent infection. Sinusitis commenced 1 to 2 weeks before and as late as 5 weeks after orbital injury. All patients were treated with IV antibiotics. Two developed an orbital abscess that required surgical drainage; 1 patient improved after an endonasal maxillary antrostomy. One patient improved on IV antibiotics alone and underwent fracture repair at a later stage. These 4 patients represent 0.8% of all cases of orbital fractures treated in the study period. Orbital cellulitis is a rare complication of orbital fracture, and seems to be more common when paranasal sinus infection preexists or occurs within several weeks of the injury. Oral antibiotics given after the orbital injury may not prevent orbital cellulitis or abscess formation. Surgery may be required to drain orbital abscess or in nonresolving cellulitis to drain the paranasal sinuses. Fracture repair, if indicated, should be delayed, particularly if an alloplastic implant is used.

Purpose To investigate the immediate and long-term outcomes of Ahmed glaucoma valve (AGV) implantation with silicone tube ligation and removable external stents. Methods This retrospective non-comparative study investigated the outcomes of AGV implantation with silicone tube ligation and removable external stents in 95 eyes (90 patients) with at least 12 months of postoperative follow-up. Qualified success was defined as an intraocular pressure (IOP) of ≤21 mmHg and ≥6 mmHg regardless of anti-glaucoma medication. Those who required additional glaucoma surgery, implant removal or who had phthisis bulbi were considered failures. Hypotony was defined as an IOP of <6 mmHg. Results Mean IOP reduced from 37.1±9.7 mmHg preoperatively to 15.2±5.6 mmHg at 12 months postoperatively (p<0.001). Qualified success was achieved in 84.2% at 1 year. Hypotony with an IOP of <6 mmHg was seen in 8.4% and an IOP of <5 mmHg in 3.2% on the first postoperative day. No case of hypotony required surgical intervention. Suprachoroidal hemorrhage did not occur in this study. When stents were removed on the first postoperative day because of an insufficient IOP decrease, the mean IOP decreased significantly from 42.0 mmHg to 14.1 mmHg (p<0.001) after 1 hour. The most common complication was hyphema, which occurred in 17.9%. Conclusions Hypotony-related early complications requiring surgical intervention were reduced by ligation and external stents in the tube. In addition, early postoperative high IOPs were managed by removing external stents. The described method can prevent postoperative hypotony after AGV implantation and showed long-term success rates comparable to those reported previously. PMID:19568356

To evaluate the efficacy of a standard double intraocular lens (IOL) system (IOL-Vip) in patients with low vision and central scotoma due to macular degeneration and assess the predictability of the residual refraction and magnification. Ophthalmology Department, Hospital General Universitario, Valencia, Spain. This interventional prospective noncomparative case series comprised 13 consecutive surgical procedures in 10 patients with central scotoma. Follow-up was 12 months. Evaluation included the difference between preoperative and postoperative best corrected visual acuity (BCVA), refraction, position of the IOLs, endothelial cell density, and occurrence of postoperative complications. Residual refraction and eye magnification were calculated using a theory developed in a previous study, and the values were compared with the clinical results. The mean BCVA was 1.37 logMAR preoperatively and 0.68 logMAR 1 year postoperatively. The mean best corrected clinical gain was 44%. There was no statistically significant difference between the clinically evaluated and theoretically calculated residual refractions (P = .17). No intraoperative or postoperative complications occurred. Implantation of the double IOL system improved BCVA in patients with low vision due to advanced maculopathy. The results were best in myopic patients (long eyes); patients with hyperopia (short eyes) had high residual refraction. The postoperative clinical gain and residual refraction were predictable, showing the feasibility of implanting a customized double IOL.

To determine the diagnostic yield of tests commonly used for vitreous fluid analysis in eyes with suspected intraocular infection or malignancy. Noncomparative interventional case series. Forty-four consecutive patients (45 eyes) treated from 1998 through 2006 with posterior segment inflammation who underwent pars plana vitrectomy for diagnostic purposes. Vitreous specimens obtained via pars plana vitrectomy were analyzed by microbiologic culture, cytologic analysis, and flow cytometry. Diagnostic yield and sensitivity of each test performed on vitreous specimens and visual outcomes of eyes that underwent diagnostic vitrectomy (DVx). Preoperative diagnoses were infection in 15 eyes and malignancy in 30 eyes. Overall, vitreous analysis identified a specific cause in 9 (20%) of 45 eyes. The overall sensitivity of DVx was 63.6%. The sensitivities of individual tests were: culture, 50%; cytologic analysis, 66.7%; and flow cytometry, 83.3%. The yields of diagnostic tests were: culture, 5.7%; cytologic analysis, 14.3%; and flow cytometry, 20.6%. Final diagnoses were infection in 6 eyes, malignancy in 9 eyes, and idiopathic in 30 eyes. Mean visual acuity improved significantly in the first 6 months after DVx. Visual acuity improved in 60% of eyes, with 37.8% of eyes improving by 3 lines or more. Analysis of vitreous fluid by widely available tests is useful in identifying intraocular infection or malignancy. Most patients experienced a substantial improvement in vision.

To describe the near-infrared (NIR) operating microscopy (NIOM) system using the NIR wavelength as the illumination source and to evaluate the feasibility of this system for lightless cataract surgery. HenAm Kim Eye Center, Haenam-Gun, South Korea. In this noncomparative interventional case series, cataract surgery was performed in 4 patients with bilateral cataract using the NIOM system in 1 eye and conventional microscopy in the fellow eye. The primary components of the system include an optical filter, a stereoscopic camera, head-mounted displays, and a recording system. This system uses invisible NIR (wavelength 850 to 1300 nm) illumination to facilitate cataract surgery without light. The differences between the NIOM system and conventional microscopy during cataract surgery were evaluated. The NIOM system provided excellent 3-dimensional viewing in real time. The image resolution was sufficient while performing all steps of cataract surgery. Immediately postoperatively and at 10 and 30 minutes and 1 hour, the visual acuity was better in the 4 eyes in which the NIOM system was used than in the 4 eyes in which conventional microscopy was used. However, using the NIOM system required good surgical skill. Lightless cataract surgery using the NIOM system seems useful for obtaining good visual acuity immediately postoperatively. The system may also reduce the incidence of light-induced retinal toxicity and the need for mydriatic administration and be a good educational tool.

Objectives  To determine whether the outcome of drug studies influenced submission and/or acceptance rates for publication in peer reviewed medical journals. Design  A six year retrospective review of publication status by study outcome for all human drug research studies conducted by a single industry sponsor (GlaxoSmithKline) that completed from 1 January 2009 to 30 June 2014 and were therefore due for manuscript submission (per the sponsor's policy) to peer reviewed journals within 18 months of study completion-that is, 31 December 2015. In addition, manuscripts from studies completing after 30 June 2014 were included irrespective of outcome if they were submitted before 31 December 2015. Setting  Studies conducted by a single industry sponsor (GlaxoSmithKline) Studies reviewed  1064 human drug research studies. Main outcome measures  All studies were assigned a publication status at 26 February 2016 including (as applicable): study completion date, date of first primary manuscript submission, number of submissions, journal decision(s), and publication date. All studies were also classified with assessors blinded to publication status as "positive" (perceived favorable outcome for the drug under study), "negative" (perceived unfavorable outcome for the drug under study), mixed, or non-comparative based on the presence and outcome of the primary outcome measure(s) for each study. "Negative" studies included safety studies in which the primary outcome was achieved but was adverse for the drug under study. For the total cohort and each of the four study outcomes, measures included descriptive statistics for study phase, time from study completion to submission and publication, and number and outcome (accepted/rejected) of publication submissions. Results  Of the 1064 studies (phase I-IV, interventional and non-interventional) included, 321 had study outcomes classified as positive, 155 as negative, 52 as mixed, and 536 as non-comparative. At the time of publication cut-off date (26 February 2016), 904 (85%) studies had been submitted for publication as full manuscripts and 751 (71%) had been successfully published or accepted, with 100 (9%) still under journal review. An additional 77 (7%) studies were conference abstracts and were not included in submission or publication rates. Submission rates by study outcome were 79% for the 321 studies with positive outcomes, 92% for the 155 with negative outcomes, 94% for the 52 with mixed outcomes, and 85% for the 536 non-comparative studies; while rates of publication at the cut-off date were 66%, 77%, 77%, and 71%, respectively. Median time from study completion to submission was 537 days (interquartile range 396-638 days) and 823 days (650-1063 days) from completion to publication, with similar times observed across study outcomes. First time acceptance rates were 56% for studies with positive outcomes and 48% for studies with negative outcomes. Over 10% of studies across all categories required three or more submissions to achieve successful publication. At the time of analysis, 83 studies had not been submitted for publication, including 49 bioequivalence studies with positive outcomes and 33 non-comparative studies. Most studies (98%, 1041/1064) had results posted to one or more public registers, including all studies subject to FDAAA (Food and Drug Administration Amendments Act) requirements for posting to www.clinicaltrials.gov Conclusions  Over the period studied, there was no evidence of submission or publication bias: 92% of studies with negative outcomes were submitted for publication by the cut-off date versus 79% of those with positive outcomes. Publication rates were slightly higher for studies with a negative (that is, unfavorable) outcome compared with a positive outcome, despite a slightly lower rate of acceptance at first submission. Many studies required multiple submission attempts before they were accepted for publication. Analyses focusing solely on publication rates do not take into account unsuccessful efforts to publish. Sponsors and journal editors should share similar information to contribute to better understanding of issues and barriers to full transparency. Published by the BMJ Publishing Group Limited.

To describe the clinical features of Ocular Toxoplasmosis in pediatric patients. A retrospective, non-comparative series of cases was studied. We reviewed the clinical records of patients 16 year old or younger diagnosed with Ocular Toxoplasmosis. Forty patients (56 eyes) were included. The mean age was 9.5 yrs old. Twenty were female. Unilateral involvement was noticed in 60% of patients. The most common symptoms were strabismus (32.1%) and reduced VA in (23.2%). An inactive retinal scar was observed in most cases (71.4%). Panuveitis was found in 8 eyes (14.2%), and posterior uveitis in 7 eyes of 7 patients (12.5%); one eye presented neuroretinitis. The most frequent location of retinochoroidal lesions was the posterior pole (72.7%). In children, ocular toxoplasmosis is most commonly diagnosed during the inactive stage. When inflammation is present, it can be severe and frequently associated with other complications such vasculitis and papillitis.

Penile cancer is a rare malignancy in Western countries, with an incidence rate of around 1 per 100,000. Due to its rarity, most treatment recommendations are based on small trials and case series reports. Furthermore, data on the resource implications are scarce. The objective of this study was to estimate the annual economic burden of treating penile cancer in England between 2006 and 2011 and the cost of treating a single case based on a modified version of the European Association of Urology penile cancer treatment guidelines. A retrospective (non-comparative) case series was performed using data extracted from Hospital Episode Statistics. Patient admission data for invasive penile cancer or carcinoma in situ of the penis was extracted by ICD-10 code and matched to data from the 2010/11 National Tariff to calculate the mean number of patients and associated annual cost. A mathematical model was simultaneously developed to estimate mean treatment costs per patient based on interventions and their associated outcomes, advised under a modified version of the European Association of Urologists Treatment Guidelines. Approximately 640 patients per year received some form of inpatient care between 2006 and 2011, amounting to an average of 1,292 spells of care; with an average of 48 patients being treated in an outpatient setting. Mean annual costs per invasive penile cancer inpatient and outpatient were £3,737 and £1,051 respectively, with total mean annual costs amounting to £2,442,020 (excluding high cost drugs). The mean cost per case, including follow-up, was estimated to be £7,421 to £8,063. Results were sensitive to the setting in which care was delivered. The treatment of penile cancer consumes similar levels of resource to other urological cancers. This should be factored in to decisions concerning new treatment modalities as well as choices around resource allocation in specialist treatment centres and the value of preventative measures.

Did You Reject Me for Someone Else? Rejections That Are Comparative Feel Worse.

PubMed

Deri, Sebastian; Zitek, Emily M

2017-12-01

Rejections differ. For those who are rejected, one important difference is whether they are rejected for someone else (comparative rejection) or no one at all (noncomparative rejection). We examined the effect of this distinction on emotional reactions to a rejection in four studies ( N = 608), one of which was fully preregistered. Our results show that comparative rejections feel worse than noncomparative rejections and that this may be because such rejections lead to an increased sense of exclusion and decreased belonging. Furthermore, we found evidence that, by default, people react to a rejection as though it were comparative-that is, in the absence of any information about whether they have been rejected for someone or no one, they react as negatively as if they were rejected for someone. Our discussion focuses on the implications of these findings, including why people often seek out information in the wake of a rejection.

Assessing the feasibility, acceptability, and potential effectiveness of a behavioral-automaticity focused lifestyle intervention for African Americans with metabolic syndrome: The Pick two to Stick to protocol.

PubMed

Fritz, Heather; Brody, Aaron; Levy, Philip

Metabolic syndrome (MetS) significantly increases the risk of developing diabetes and cardiovascular disease. Being physically active and eating a healthy diet can reduce MetS risk factors. Too frequently, however, studies report that the effects of interventions targeting those factors are not maintained once interventions are withdrawn. A potential solution to the problem is targeting behavioral automaticity (habit-development) to aid in initiation and maintenance of health-behavior changes. The Pick two to Stick To (P2S2), is an 8-week, theory-based hybrid (face-to-face/telecoaching) habit focused lifestyle intervention designed to increase healthful physical activity and dietary behavioral automaticity. The purpose of this article is to describe the rationale and protocol for evaluating the P2S2 program's feasibility, acceptability and potential effectiveness. Using a prospective, non-comparative design, the P2S2 program will be implemented by trained occupational therapy 'coaches' to 40 African Americans aged 40 and above with MetS recruited from the emergency department. Semi-structured interviews with participants, bi-weekly research meetings with study staff, and observations of intervention delivery will provide data for a process evaluation. Estimates of effectiveness include weight, blood pressure, waist circumference, BMI, and behavioral automaticity measures that will be collected at baseline and week 20. The P2S2 program could facilitate the development of healthful dietary and physical activity habits in an underserved population. Whether interventions aimed at changing habits can feasibly influence this automaticity, particularly for high-risk, low resource communities where other barriers exist, is not known. This pilot study, therefore, will fill an important gap, providing insight to inform subsequent trials.

PurposeDry eye syndrome (DES) causes significant morbidity. Trials of blood-derived products in treatment of the condition show promising results. However, their production is expensive and time-consuming. We investigate fingerprick autologous blood (FAB) as an alternative low-cost, readily accessible treatment for DES.Patients and methodsProspective, non-comparative, interventional case series. In total, 29 eyes of 16 DES patients (2 males and 14 females) from two NHS sites in the United Kingdom. Patients instructed to clean a finger, prick with a blood lancet, and apply a drop of blood to the lower fornix of the affected eye(s), 4 times daily for 8 weeks then stop and review 4 weeks later. Follow-up visits occurred ~3 days, 2, 4, 8 weeks into therapy, and 4 weeks post-cessation. At each visit, visual acuity, corneal staining, Schirmer's test, tear break-up time (TBUT), and ocular comfort index (OCI) were measured, and photographs taken. Results were analysed using Student's paired t-test.ResultsAt 8 weeks, there was improvement in mean Oxford corneal staining grade (3.31 to 2.07 (P<0.0001)), TBUT (5.00 to 7.80 s (P<0.05)), visual acuity (0.08 to 0.01 LogMAR equivalent (P<0.05)), and OCI score (56.03 to 39.72 (P<0.0001)). There was no statistically significant change in Schirmer's test results. Four weeks post-cessation versus immediately after completion of FAB therapy, mean staining grade worsened from 2.07 to 2.86 (P<0.0001). OCI score worsened from 39.72 to 44.67 (P<0.05).ConclusionsIn our limited case series FAB appears to be a safe and effective treatment for DES.

To summarize our clinical experience with implanting Baerveldt glaucoma tube shunts through the ciliary sulcus in eyes with a posterior chamber intraocular lens and shallow anterior chambers, corneal transplants, guttata or edema. A retrospective interventional nonrandomized noncomparative case series. Main outcome measure was postoperative corneal status. Secondary outcome measures included postoperative intraocular pressure (IOP), visual acuity and complications. Thirty-six eyes of 32 patients were identified through chart review. Follow-up period was 21.8+/-16.6 months (mean+/-standard deviation, range: 4.0 to 58.5 mo). At final visit, all 23 preoperative clear native corneas and 6 of 7 corneal transplants remained clear. Thus, of the 30 preoperative clear corneas, only 1 decompensated. Preoperative IOP was 27.9+/-11.8 mm Hg (range: 12 to 59 mm Hg), reduced postoperatively to 10.1+/-3.9 mm Hg (range: 2 to 21 mm Hg, P=0.0001), a reduction of 58.2%+/-19.3% (range: 5.0% to 95.4%). Final IOP was >or=5 and

To describe the autofluorescence features of choroidal nevi. Noncomparative case series. Sixty-four consecutive patients. Correlation of fundus photography with autofluorescence photography. Autofluorescence features of choroidal nevus and overlying retinal pigment epithelium (RPE). The mean patient age was 62 years. The choroidal nevus was a mean of 5 mm from the optic disk and foveola. The mean tumor basal dimension was 5.0 mm and mean tumor thickness was 1.0 mm. The choroidal nevus showed hypoautofluorescence in 56%, isoautofluorescence in 19%, and hyperautofluorescence in 25%. The autofluorescence features appeared unaffected by tumor thickness, but increasing tumor base and disrupted overlying RPE appeared to produce slightly brighter autofluorescence. Nevi located in the macular region showed darker hypoautofluorescence than those outside the macular region. Overlying RPE hyperplasia, atrophy, and fibrous metaplasia were generally hypoautofluorescent. Drusen, subretinal fluid, and orange pigment were generally hyperautofluorescent. The brightest hyperautofluorescence was found with orange pigment. Choroidal nevus shows little intrinsic autofluorescence. Overlying RPE alterations show dramatic autofluorescence ranging from dark hypoautofluorescence of RPE atrophy to bright hyperautofluorescence of orange pigment.

To investigate the outcomes of Descemet membrane endothelial keratoplasty (DMEK) using prestripped donor tissue prepared by an eye bank. Retrospective, noncomparative case series. This retrospective, noncomparative, observational study investigated the outcomes of the first 40 consecutive DMEK procedures performed by a single surgeon using prestripped tissues prepared by a single eye bank during the period September 17, 2013 to July 1, 2014. A new technique to unfold the Descemet membrane grafts using a single cannula was described. Medical records were reviewed to obtain the prestripped and poststripped endothelial cell counts (ECC), postoperative ECC, visual acuity measurements, and complications. Of the 43 prestripped tissues received, 40 were transplanted. The leading indications for DMEK were Fuchs endothelial corneal dystrophy (n = 28) and bullous keratopathy (n = 11). Nine DMEK procedures were performed in combination with phacoemulsification and posterior chamber intraocular lens implantation. Six patients had undergone prior glaucoma surgeries. The mean follow-up duration was 5.3 months (range, 1 week to 11 months). Preoperative spectacle-corrected visual acuity was ≤20/200 in 8 patients (20%) and ≤20/40 in 37 patients (92.5%). Primary graft failure occurred in the first case. Thirty-eight patients had improved vision postoperatively. Among the 39 patients who had successful DMEK, postoperative BCVA was ≥20/20 in 20 patients (51.2%), ≥20/25 in 30 patients (76.9%), and ≥20/40 in 34 patients (87.2%) by the last follow-up. There was no secondary graft failure. Rejection occurred in 2 patients because of self-discontinuation of topical corticosteroid. The most common complication was partial detachment requiring air injection (11 of 40 patients; 27.5%). Mean ECC loss after stripping of Descemet membrane was 3.9% (range, 6.5% gain to 14.5% loss). During the first 6 months after transplantation, the average ECC loss was 30.5% (range, 3.8%-67.4% loss). DMEK using eye bank-prepared tissue achieved outcomes comparable to those reported for DMEK using surgeon-prepared tissue. Published by Elsevier Inc.

We conducted a retrospective non-comparative cross-sectional study in Lubumbashi on factors associated with road accidents. To contribute to the reduction of morbidity and mortality related to road accidents based on a better understanding of this phenomenon in the city of Lubumbashi, to assess the frequency and the growth of road accidents in the city of Lubumbashi and to determine the factors predisposing to these accidents. This non-controlled retrospective cross-sectional descriptive study covered the period from 1st January to 31st December 2008, and included all cases of vehicles registered by the police department after an accident. A total of 1,915 road traffic were reported, mostly caused by public transport vehicles (59%) driven by young adult males (89% of cases) with a mean age of 28 years. The main cause was speeding combined with other factors (34% of cases). The majority of these accidents occurred in the city of Lubumbashi (52.9% of cases) between 6:00 a.m. and 6:00 p.m. (74% of cases). Transit vehicles were exposed to a greater risk of road accidents (59%). There is an urgent need for accurate information on the rules of the road for drivers and road users to reduce the mortality and morbidity due to road accidents.

Abstract The study aimed to evaluate the therapeutic effects of deep anterior lamellar keratoplasty (DALK) using glycerol-cryopreserved corneal tissues (GCCTs) in patients with refractive herpes simplex keratitis (HSK). This article was a retrospective, noncomparative, and interventional case series. Patients with HSK underwent DALK using GCCTs at Shanghai Tongji Hospital from 2012 to 2015. The best spectacle corrected visual acuity, recurrent inflammation, graft status, postoperative central graft thickness, and pre/postoperative complications were detected. The follow-up ranged from 24.4 ± 5.6 months (range: 16–38 months). Overall, the best spectacle corrected visual acuity was increased from HM/10 cm to 0.15 before surgery to 0.41 ± 0.14 (range: 0.1–0.8; P < 0.05) at 12 months postoperatively. Intraoperative microperforation occurred in 4 eyes (14.81%), and rejection episodes were encountered in 3 of 27 eyes (11.1%), and all of the eyes reversed. HSK recurred in 2 eyes (7.41%), 1 eye with repeated recurring HSK, and eventually led to perpetual corneal opacity and the patient refused a retransplantation. The mean entire corneal thickness was 0.519 ± 0.018 mm (range: 0.5–0.56 mm) and the mean graft thickness was 0.405 ± 0.033 mm (range: 0.35–0.47 mm) in the final follow-up. The DALK using GCCTs was proven to be an effective and safe therapy in treating refractory HSK. PMID:27684823

To determine the efficacy of simultaneous peripheral crescentic lamellar keratoplasty (LK) and central penetrating keratoplasty (PK) for advanced pellucid marginal degeneration (PMD). Retrospective, noncomparative, interventional case series. Five patients with advanced PMD. Simultaneous peripheral crescentic LK and central PK followed by selective suture removal and astigmatic keratotomy in the postoperative period. These included interval of time required for visual rehabilitation, best spectacle-corrected visual acuity achieved, and amount of corneal astigmatism, as measured by videokeratography. Measuring the change in corneal astigmatism by videokeratography over the subsequent follow-up period after spectacle correction had been prescribed assessed stability of the achieved refraction. Visual acuity results were 20/40 in three eyes, 20/80 in one eye, and 20/400 in one eye. The latter two had decreased acuity from posterior subcapsular cataract formation, which may have been caused by topical steroid use. The time required for visual rehabilitation ranged from 5.13 to 10.93 (mean, 9.92) months, and the amount of corneal astigmatism at the end of this period ranged from 0.3 diopters (D) to 5.3 D. A tendency for an increase in "with the rule astigmatism" after the rehabilitation period was noted. Two patients had elevations of intraocular pressure that responded to reduction in topical steroid dose. The short-term results with this technique are excellent in that it provides early and stable visual rehabilitation in patients with advanced PMD. Low to moderate levels of postkeratoplasty astigmatism were achieved in all the eyes treated. The usual tendency of an increase in "against the rule astigmatism" that occurs when PK alone is done for PMD was eliminated.

To determine the contraceptive efficacy of the lactational amenorrhoea method. Non-comparative prospective trial. Urban Manila, the Philippines. 485 lower income, educated women with extensive experience of breast feeding. Women were offered all available contraceptives for use after birth. Those who chose the lactational amenorrhoea method were taught the method, screened for the study, and followed for 12 months to determine the risk of pregnancy when the method was used. Life table pregnancy rates during correct and incorrect use of the method, censored monthly in the event of sexual abstinence or the use of another contraceptive method. The lactational amenorrhoea method was 99% effective when used correctly (that is, during lactational amenorrhoea and full or nearly full breast feeding for up to six months). At 12 months the effectiveness during amenorrhoea dropped to 97%. The lactational amenorrhoea method provided as much protection from pregnancy as non-breast feeding women experience with non-medicated intrauterine devices and barrier methods. The contraceptive effect of lactation cannot be attributed to lactational or postpartum abstinence.

The authors examined the effects of arts education on cognition, behavior, and brain of children. Twenty-nine nonclinical children participated in a 15-week arts education program that was composed of either creative movement or musical arts. Children completed the Wisconsin Card Sorting Test, clinical scales, and brain magnetic resonance imaging before and after the intervention. Following program completion, performances on the Wisconsin Card Sorting Test, the Children's Depression Inventory scores, and conduct disorder scores were significantly improved. Furthermore, cortical thickness in the left postcentral gyrus and superior parietal lobule were increased, and the mean diffusivity values in the right posterior corona radiate and superior longitudinal fasciculus were decreased. Positive correlations between changes in cognitive measurements and changes in cortical thickness were observed. This preliminary study suggests a positive effect of arts education on executive functions in association with brain changes. However, these findings must be interpreted with caution due to the noncomparative study design. © The Author(s) 2015.

Evaluation of a protocol of total intraluminal occlusion of Baerveldt shunts and its effects on early postoperative intraocular pressure (IOP) control and hypotony-related complications. This was a noncomparative, prospective, and interventional study. Glaucoma patients were recruited to undergo Baerveldt shunt surgery. A total of 116 eyes of 112 patients were enrolled. During shunt implantation, aqueous outflow was restricted using an intraluminal occluding stent inserted through the entire tube length, with and without external ligation, to halt aqueous flow. Postoperatively, eyes underwent ligature laser suture lysis and partial or complete stent removals, at predetermined time intervals. Loss of postoperative IOP control was categorized as transient or persistent hypotony (IOP≤5 mm Hg) or hypertony (IOP>21 mm Hg). Patients were followed up for 1 year. Preoperatively median IOP was 23 mm Hg (mean 26 mm Hg, SD 12 mm Hg), median number of glaucoma medications was 3.0 (mean 3.0, SD 1.2). During year 1, laser suture lysis was performed in 30 eyes (26%) and stent removal in 93 eyes (80%) (23 partial; 70 complete). There was 1 case of transient hypotony, no cases of persistent hypotony, 10 of transient hypertony, and 3 of persistent hypertony. Nine eyes had IOP≤5 mm Hg at ≥1 time points and hypotony-related complications occurred in 8 eyes (7%). At 1 year, median IOP was 12 mm Hg (mean 13 mm Hg, SD 4 mm Hg) with a median of 1.0 glaucoma medications (mean 1.1, SD 1.3). The cumulative probability of failure during the first 12 months follow-up was 6% (n=7). Overall postoperative complications occurred in 11 eyes (9%). The surgical and postoperative protocol resulted in controlled, step-wise reductions of IOP with low rates of hypotony and related complications.

To assess the effects of treatments for non-metastatic invasive squamous cell carcinoma (SCC) of the skin using evidence from observational studies, given the paucity of evidence from randomised controlled trials. Systematic review of observational studies. Medline, Embase, to December 2012. Observational studies of interventions for primary, non-metastatic, invasive, SCC of the skin that reported recurrence during follow-up, quality of life, initial response to treatment, adverse events, cosmetic appearance, or death from disease. Studies were excluded if data for primary cutaneous SCC was not separable from other data. Data were extracted independently by two reviewers. Meta-analysis was performed where appropriate using a random effects model to estimate the pooled proportion of an event with 95% confidence intervals. 118 publications were included, covering seven treatment modalities. Pooled estimates of recurrence of SCCs were lowest after cryotherapy (0.8% (95% confidence interval 0.1% to 2%)) and curettage and electrodesiccation (1.7% (0.5% to 3.4%)), but most treated SCCs were small, low risk lesions. After Mohs micrographic surgery, the pooled estimate of local recurrence during variable follow-up periods from 10 studies was 3.0% (2.2% to 3.9%), which was non-significantly lower than the pooled average local recurrence of 5.4% (2.5% to 9.1%) after standard surgical excision (12 studies), and 6.4% (3.0% to 11.0%) after external radiotherapy (7 studies). After an apparently successful initial response of SCCs to photodynamic therapy, pooled average recurrence of 26.4% (12.3% to 43.7%; 8 studies) was significantly higher than other treatments. Evidence was limited for laser treatment (1 study) and for topical and systemic treatments (mostly single case reports or small non-comparative series with limited follow-up). Many observational studies have looked at different treatment modalities for SCC, but the evidence base for the effectiveness of these interventions is poor. Comparison of outcomes after different treatments should be interpreted cautiously owing to biases inherent in the types of study included, and lack of direct comparisons to enable the estimation of relative treatment effect. Further evidence is needed to develop a prognostic model and stratify individuals at high risk of developing SCC, to improve the evidence base for this common cancer and to optimise clinical management.

Blonanserin: a review of its use in the management of schizophrenia.

Deeks, Emma D; Keating, Gillian M

2010-01-01

Oral blonanserin (Lonasen) is an atypical antipsychotic agent indicated for use in patients with schizophrenia in Japan and Korea. It is effective in the treatment of patients with schizophrenia, providing short- and long-term efficacy against both the positive and negative symptoms of the disorder in several randomized and noncomparative trials. Notably, in two randomized, double-blind trials of 8 weeks' duration, blonanserin was noninferior to haloperidol or risperidone for primary endpoints, although it appeared to be better than haloperidol in improving negative symptoms. Blonanserin is generally well tolerated and appears to have an acceptable profile in terms of bodyweight gain. Potential tolerability benefits of the drug in short-term trials included fewer extrapyramidal symptoms than haloperidol and fewer reports of prolactin level increases or hyperprolactinaemia than risperidone. Nevertheless, extrapyramidal symptoms and hyperprolactinaemia were among the most common adverse reactions associated with blonanserin in noncomparative long-term studies. Further prospective and long-term comparative studies are required in order to definitively position blonanserin with respect to other antipsychotic agents. In the meantime, available clinical data suggest that blonanserin is an effective and generally well tolerated option for the short-term treatment of schizophrenia and for those requiring longer-term therapy.

Educational psychology and the effectiveness of inclusive education/mainstreaming.

Lindsay, Geoff

Inclusive education/mainstreaming is a key policy objective for the education of children and young people with special educational needs (SEN) and disabilities. This paper reviews the literature on the effectiveness of inclusive education/mainstreaming. The focus is on evidence for effects in terms of child outcomes with examination also of evidence on processes that support effectiveness. The review covers a range of SEN and children from pre-school to the end of compulsory education. Following an historical review of evidence on inclusive education/mainstreaming, the core of the paper is a detailed examination of all the papers published in eight journals from the field of special education published 2001-2005 (N=1373): Journal of Special Education, Exceptional Children, Learning Disabilities Research and Practice, Journal of Learning Disabilities, Remedial and Special Education, British Journal of Special Education, European Journal of Special Needs Education, and the International Journal of Inclusive Education. The derived categories were: comparative studies of outcomes: other outcome studies; non-comparative qualitative studies including non-experimental case studies; teacher practice and development; teacher attitudes; and the use of teaching assistants. Only 14 papers (1.0%) were identified as comparative outcome studies of children with some form of SEN. Measures used varied but included social as well as educational outcomes. Other papers included qualitative studies of inclusive practice, some of which used a non-comparative case study design while others were based on respondent's judgements, or explored process factors including teacher attitudes and the use of teaching assistants. Inclusive education/mainstreaming has been promoted on two bases: the rights of children to be included in mainstream education and the proposition that inclusive education is more effective. This review focuses on the latter issue. The evidence from this review does not provide a clear endorsement for the positive effects of inclusion. There is a lack of evidence from appropriate studies and, where evidence does exist, the balance was only marginally positive. It is argued that the policy has been driven by a concern for children's rights. The important task now is to research more thoroughly the mediators and moderators that support the optimal education for children with SEN and disabilities and, as a consequence, develop an evidence-based approach to these children's education.

The purpose of this study was to determine the clinical benefits of intense-pulsed-light therapy for the treatment of dry-eye disease caused by meibomian gland dysfunction (MGD). MGD is the leading cause of evaporative dry eye disease. It is currently treated with a range of methods that have been shown to be only somewhat effective, leading to the need for advanced treatment options. A retrospective noncomparative interventional case series was conducted with 91 patients presenting with severe dry eye syndrome. Treatment included intense-pulsed-light therapy and gland expression at a single outpatient clinic over a 30-month study. Pre/post tear breakup time data were available for a subset of 78 patients. For all patients, a specially developed technique for the treatment of dry eye syndrome was applied as a series of monthly treatments until there was adequate improvement in dry eye syndrome symptoms by physician judgment, or until patient discontinuation. Primary outcomes included change in tear breakup time, self-reported patient satisfaction, and adverse events. Physician-judged improvement in dry eye tear breakup time was found for 68 of 78 patients (87%) with seven treatment visits and four maintenance visits on average (medians), and 93% of patients reported post-treatment satisfaction with degree of dry eye syndrome symptoms. Adverse events, most typically redness or swelling, were found for 13% of patients. No serious adverse events were found. Although preliminary, study results of intense-pulsed-light therapy treatment for dry eye syndrome caused by meibomian gland dysfunction are promising. A multisite clinical trial with a larger sample, treatment comparison groups, and randomized controlled trials is currently underway.

To evaluate minor salivary glands and labial mucous membrane graft in patients with severe symblepharon and dry eye secondary to Stevens-Johnson syndrome (SJS). A prospective, non-comparative, interventional case series of 19 patients with severe symblepharon and dry eye secondary to SJS who underwent labial mucous membrane and minor salivary glands transplantation. A complete ophthalmic examination including the Schirmer I test was performed prior to and following surgery. All patients had a preoperative Schirmer I test value of zero. Nineteen patients with severe symblepharon and dry eye secondary to SJS were included in the study. There was a statistically significant improvement in the best spectacle-corrected visual acuity in eight patients (t test; p=0.0070). Values obtained in the Schirmer I test improved significantly in 14 eyes (73.7%) 6 months following surgery (χ(2) test; p=0.0094). A statistically significant increase in tear production (Schirmer I test) was found in eyes that received more than 10 glands per graft compared with eyes that received fewer glands (χ(2) test; p=0.0096). Corneal transparency improved significantly in 11 (72.2%) eyes and corneal neovascularisation improved significantly in five eyes (29.4%) (McNemar test; p=0.001 and p=0.0005). The symptoms questionnaire revealed improvement in foreign body sensation in 53.6% of the patients, in photophobia in 50.2% and in pain in 54.8% (Kruskal-Wallis test; p=0.0167). Labial mucous membrane and minor salivary glands transplantation were found to constitute a good option for the treatment of severe symblepharon and dry eye secondary to SJS. This may be considered as a step prior to limbal stem cell and corneal transplantation in these patients.

Purpose. To evaluate the visual outcomes and effect of phacoemulsification surgery on the progression of neovascular age-related macular degeneration (AMD). Methods. Retrospective, noncomparative, and interventional case series. Thirty eyes from 29 subjects with neovascular AMD treated with intravitreal antivascular endothelial growth factor (VEGF) injections who underwent phacoemulsification and had a postsurgery follow-up of 6 months were included. LogMAR best corrected visual acuity (BCVA) was assessed preoperatively; 1 month, 3 months, and 6 months postoperatively; and finally at the last visit. The frequency of anti-VEGF therapy, calculated as the number of intravitreal injections per month, and central macular thickness (CMT) before and after cataract surgery were determined. Results. Median (range) logMAR BCVA was 0.69 (0.16 to 1.32) preoperatively; 0.55 (-0.04 to 1.32) at 1 month, 0.52 (-0.1 to 1.32) at 3 months, and 0.50 (0.0 to 1.32) at 6 months postoperatively; and 0.6 (0.0 to 1.4) at final visit (P = 0.0011). There was no difference in the frequency of anti-VEGF injections between the immediate 6 months before and after phacoemulsification, which was equal to 0.1667 injections per month (P = 0.6377). Median CMT measured 203  μ m preoperatively, which temporarily increased to 238  μ m at 1 month after surgery (P = 0.0093) and then spontaneously returned to baseline, measuring 212.5  μ m at 3 months postoperatively (P = 0.3811). Conclusion. Phacoemulsification surgery significantly improved vision in patients with neovascular AMD, with no increased need for anti-VEGF injections to keep the macula dry postoperatively.

Methanol poisoning can cause an optic neuropathy that is usually severe and irreversible and often occurs after ingestion of illicit or homemade alcoholic beverages. In this study, we evaluated the potential neuroprotective effect of erythropoietin (EPO) on visual acuity (VA) in patients with methanol optic neuropathy. In a prospective, noncomparative interventional case series, consecutive patients with methanol optic neuropathy after alcoholic beverage ingestion were included. All patients initially received systemic therapy including metabolic stabilization and detoxification. Treatment with intravenous recombinant human EPO consisted of 20,000 units/day for 3 successive days. Depending on clinical response, some patients received a second course of EPO. VA, funduscopy, and spectral domain optical coherence tomography were assessed during the study. Main outcome measure was VA. Thirty-two eyes of 16 patients with methanol optic neuropathy were included. Mean age was 34.2 years (±13.3 years). The mean time interval between methanol ingestion and treatment with intravenous EPO was 9.1 days (±5.56 days). Mean follow-up after treatment was 7.5 months (±5.88 months). Median VA in the better eye of each patient before treatment was light perception (range: 3.90-0.60 logMAR). Median last acuity after treatment in the best eye was 1.00 logMAR (range: 3.90-0.00 logMAR). VA significantly increased in the last follow-up examination (P < 0.0001). Age and time to EPO treatment after methanol ingestion were not significantly related to final VA. No ocular or systemic complications occurred in our patient cohort. Intravenous EPO appears to improve VA in patients with methanol optic neuropathy and may represent a promising treatment for this disorder.

Pressure ulcers affect as many as 3 million Americans and are major sources of morbidity, mortality, and health care costs. To summarize evidence comparing the effectiveness and safety of treatment strategies for adults with pressure ulcers. MEDLINE, EMBASE, CINAHL, Evidence-Based Medicine Reviews, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, and Health Technology Assessment Database for English- or foreign-language studies; reference lists; gray literature; and individual product packets from manufacturers (January 1985 to October 2012). Randomized trials and comparative observational studies of treatments for pressure ulcers in adults and noncomparative intervention series (n > 50) for surgical interventions and evaluation of harms. Data were extracted and evaluated for accuracy of the extraction, quality of included studies, and strength of evidence. 174 studies met inclusion criteria and 92 evaluated complete wound healing. In comparison with standard care, placebo, or sham interventions, moderate-strength evidence showed that air-fluidized beds (5 studies [n = 908]; high consistency), protein-containing nutritional supplements (12 studies [n = 562]; high consistency), radiant heat dressings (4 studies [n = 160]; moderate consistency), and electrical stimulation (9 studies [n = 397]; moderate consistency) improved healing of pressure ulcers. Low-strength evidence showed that alternating-pressure surfaces, hydrocolloid dressings, platelet-derived growth factor, and light therapy improved healing of pressure ulcers. The evidence about harms was limited. Applicability of results is limited by study quality, heterogeneity in methods and outcomes, and inadequate duration to assess complete wound healing. Moderate-strength evidence shows that healing of pressure ulcers in adults is improved with the use of air-fluidized beds, protein supplementation, radiant heat dressings, and electrical stimulation.

To evaluate the effectiveness of an orbital tissue expander designed to stimulate orbital bone growth in an anophthalmic socket. Retrospective, noncomparative, interventional case series. Institutional. Nine consecutive patients with unilateral congenital anophthalmos. The orbital tissue expander is made of an inflatable silicone globe sliding on a titanium T-plate secured to the lateral orbital rim with screws. The globe is inflated by a transconjunctival injection of normal saline through a 30-gauge needle to a final volume of approximately 5 cm(3). Computed tomography scans were used to determine the orbital volume. The data studied were: demographics, prior orbital expansion procedures, secondary interventions, orbital symmetry, and implant-related complications. The primary outcome measure was the orbital volume change, and the secondary outcome measures were changes in forehead, brow, and zygomatic eminence contour and adverse events. The average patient age at implantation was 41.89 ± 39.42 months (range, 9 to 108 months). The initial average volume of inflation was 3.00 ± 0.87 cm(3) (range, 2.0 to 4.0 cm(3)), and the average final volume of 4.33 ± 0.50 cm(3) (range, 4.0 to 5.0 cm(3)) was achieved. The duration of expansion was 18.89 ± 8.80 months (range, 4 to 26 months). All patients demonstrated an average increase in the orbital tissue expander implanted orbital volume of 5.112 ± 2.173 cm(3) (range, 2.81 to 10.38 cm(3)). The average difference between the volume of the implanted and the initial contralateral orbit was 5.68 ± 2.34 cm(3), which decreased to 2.53 ± 1.80 cm(3) at the final measurement (P < .001, paired t test). All implants remained inflated except for 2 iatrogenic punctures at the second inflation and 1 that was the result of implant failure. All were replaced. The integrated orbital tissue expander is safe and effective in stimulating anophthalmic socket bone growth. Copyright © 2011 Elsevier Inc. All rights reserved.

To evaluate the efficacy and safety of the paracetamol-tramadol combination (PTC) in treating moderate-to-severe pain, in patients aged 65 years and over within general practitioner (GP) practice centers. This was an observational, non-interventional, longitudinal, multicenter, open, non-comparative, prospective study. This intermediary analysis was of patients recruited before the French Health Authority confirmation (25th June, 2009) of the EMEA decision to withdraw all analgesics containing dextropropoxyphen. Trial registration information: This study has been submitted for approval to the CNIL and French Medical Council (CNOM) only. A total of 2663 patients aged 65 years or over were assessed 1 month after inclusion in the study. PTC was prescribed as first-line treatment in 30% of patients and, in the other cases, after failed or inadequate efficacy (69.8%), and/or as a result of safety problems (7.8%) with at least one other analgesic. During the month of the study period 14.7% of patients received an additional rescue analgesic. The study confirmed the efficacy of PTC with regard to pain intensity (-3.1 points reduction of pain scored 6.1 points on inclusion), pain relief (64.8% of patients experienced significant pain relief), patient satisfaction (90.5% of patients satisfied or completely satisfied) and clinical global impression evaluated by the patient (78.7% much or very much improved), regardless of the pain etiologies or duration of the underlying pathology. PTC was well-tolerated in this patient group, who had a mean age of 73.6 ± 6.6 years. A total of 119 patients (4.5%) reported at least one adverse event (AE). All were known and predictable AEs. This percentage is comparable to that found under similar conditions in patients of all ages (4.2%). PTC, due to the complementary action of its two analgesics, is effective in treating the different types of pain in a GP's practice setting and is well-tolerated, even in an elderly population. Study limitations include all those inherent to non-interventional and open-label observations.

Objective Glossopharyngeal neuralgia (GPN) is a very rare condition, affecting the patient's quality of life. We report our experience in drug-resistant, idiopathic GPN, treated with Gamma Knife radiosurgery (GKRS), in terms of safety and efficiency, on a very long-term basis. Methods The study was opened, self-controlled, non-comparative and bicentric (Marseille and Lausanne University Hospitals). Patients treated with GKRS between 2003 and 2015 (models C, 4C and Perfexion) were included. A single 4-mm isocentre was positioned in the cisternal portion of the glossopharyngeal nerve, with a targeting based both on magnetic resonance imaging (MRI) and computed tomography (CT). The mean maximal dose delivered was 81.4 ± 6.7 Gy (median = 85 Gy, range = 60-90 Gy at the 100% isodose line). Results Twenty-one patients (11 women, 10 men) benefited from 25 procedures. The mean follow-up period was 5.2 ± 3 years (range = 0.9-12.1 years). Seventeen (81%) were initially pain-free after GKRS. At three months, six months and one year after radiosurgery, the percentage of patients with good outcome (BNI classes I to IIIA) was 87.6%, 100% and 81.8%, respectively. Ten cases (58.8%) from the initial pain-free ones had a recurrence, after a mean period of 13.6 ± 10.4 months (range = 3.1-36.6 months). Only three patients (14.2%) had recurrences (two for each one of them) requiring further surgeries. Three patients underwent a second GKRS procedure; one case needed a third GKRS. The former procedures were performed at 7, 17, 19 and 30 months after the first one, respectively. Furthermore, two patients needed additional interventions. At last follow-up, 17 cases (80.9%) were still pain-free without medication. The actuarial pain relief without new surgery was 83%. A transient complication (paraesthesia of the edge of the tongue) was seen in one case (4.8%). Conclusion GKRS is a valuable, minimally invasive, surgical alternative for idiopathic GPN, with a very high short- and long-term efficacy and without permanent complications. A quality imaging, including T2 CISS/Fiesta MRI and bone CT acquisitions for good visualisation of the nerve and the other bony anatomic landmarks, is essential for targeting accuracy and successful therapy.

We aimed to update the 2011 recommendations for the prevention and treatment of anticipatory nausea and vomiting in children and adults receiving chemotherapy. The original systematic literature search was updated. Randomized studies were included in the evidence to support this guideline if they as follows: were primary studies published in a journal in full text (i.e., abstracts, letters, book chapters, and dissertations were excluded); published in English; evaluated an intervention for the prevention or treatment of anticipatory nausea and vomiting; reported the proportion of patients experiencing complete control of anticipatory nausea and vomiting consistently and; included at least ten participants per study arm for comparative studies and at least ten participants overall for noncomparative studies. Eighty-eight new citations were identified. Of these, nine were brought to full-text screening; none met inclusion criteria. The guideline panel continues to recommend that anticipatory nausea and vomiting are best prevented through optimization of acute and delayed phase chemotherapy-induced nausea and vomiting control. Benzodiazepines and behavioral therapies, in particular progressive muscle relaxation training, systematic desensitization and hypnosis, continue to be recommended for the treatment of anticipatory nausea and vomiting. No new information regarding interventions aimed at treating or preventing ANV that met criteria for inclusion in this systematic review was identified. The 2015 MASCC recommendations affirm the content of the 2009 MASCC recommendations for the prevention and treatment of anticipatory nausea and vomiting.

To evaluate the safety and efficacy of the ultrasonic circular cyclo-coagulation procedure using high-intensity focused ultrasound by a miniaturized annular device containing 6 piezoceramic transducers in patients with refractory glaucoma. This was a prospective interventional noncomparative study of 20 eyes of 20 patients with refractory glaucoma. All eyes were treated with 6 activated transducers operating at 21 MHz. Ultrasound biomicroscopy and a complete ophthalmic examination were performed before the procedure and at 1 day, 1 week, and 1, 3, 6, and 12 months after the procedure. Primary outcomes were surgical success (defined as intraocular pressure (IOP) reduction from baseline ≥20% and IOP >5 mm Hg) at the last follow-up visit. Secondary outcomes were mean IOP at each follow-up visit compared to baseline, medication use, complications, and re-interventions. Intraocular pressure was significantly reduced (p<0.01) from a mean preoperative value of 36.4 ± 5.7 mm Hg to a mean postoperative value of 22.5 ± 10.3 mm Hg at 12 months. Four patients needed to be re-treated. The mean IOP reduction achieved was 38%. Surgical success was achieved in 13 of 20 eyes (65%). No major intraoperative or postoperative complications occurred. Ultrasonic circular cyclo-coagulation using high-intensity focused ultrasound delivered by a circular miniaturized device containing 6 piezoceramic transducers is an effective and well-tolerated method to reduce IOP in patients with refractory glaucoma.

To report the effects of oral trimethoprim/sulfamethoxazole and intravitreal bevacizumab injection in the treatment of ocular toxoplasmosis-associated choroidal neovascular lesions (CNV). This was a noncomparative, nonrandomized, consecutive case series. All eyes with ocular toxoplasmosis-associated CNV received one intravitreal bevacizumab injection under the coverage of oral trimethoprim/sulfamethoxazole. The changes in best-corrected visual acuity were recorded. Serial fundus photography, fluorescein angiography, optical coherence tomography, and indocyanine green angiography were performed to measure the treatment efficacy. Three eyes of two patients with a history of ocular toxoplasmosis had active CNV demonstrated by fluorescein angiography and optical coherence tomography. Each was treated with oral trimethoprim/sulfamethoxazole and one intravitreal bevacizumab injection. Best-corrected visual acuity, fundus photographs, fluorescein angiography, optical coherence tomography, and indocyanine green angiography all showed favorable results. No ocular or systemic complications were noted. In all three eyes, the CNV subsided and vision improved. Oral trimethoprim/sulfamethoxazole is an effective and less expensive antibiotic against Toxoplasma gondii. Intravitreal bevacizumab injection appears to be a well-tolerated treatment for toxoplasmosis-associated CNV and has the potential as an adjuvant therapy to improve final vision. More cases and further studies are required.

Benchmarking Strategies for Measuring the Quality of Healthcare: Problems and Prospects

Over the last few years, increasing attention has been directed toward the problems inherent to measuring the quality of healthcare and implementing benchmarking strategies. Besides offering accreditation and certification processes, recent approaches measure the performance of healthcare institutions in order to evaluate their effectiveness, defined as the capacity to provide treatment that modifies and improves the patient's state of health. This paper, dealing with hospital effectiveness, focuses on research methods for effectiveness analyses within a strategy comparing different healthcare institutions. The paper, after having introduced readers to the principle debates on benchmarking strategies, which depend on the perspective and type of indicators used, focuses on the methodological problems related to performing consistent benchmarking analyses. Particularly, statistical methods suitable for controlling case-mix, analyzing aggregate data, rare events, and continuous outcomes measured with error are examined. Specific challenges of benchmarking strategies, such as the risk of risk adjustment (case-mix fallacy, underreporting, risk of comparing noncomparable hospitals), selection bias, and possible strategies for the development of consistent benchmarking analyses, are discussed. Finally, to demonstrate the feasibility of the illustrated benchmarking strategies, an application focused on determining regional benchmarks for patient satisfaction (using 2009 Lombardy Region Patient Satisfaction Questionnaire) is proposed.

To investigate the ocular and systemic manifestations of retinal vasculitis in HLA-B27-positive patients. Retrospective noncomparative case series of 9 HLA-B27-positive patients with uveitis and retinal vasculitis. Main outcome measures consisted of ocular and angiographic findings and assessment of any additional systemic disorders. Three male and 6 female HLA-B27-positive patients with a median age of 32 years were diagnosed with retinal vasculitis. Concurrent intraocular inflammation was noted in all patients. All patients suffered from extensive vasculitis of the large retinal veins. Five patients developed retinal vasculitis at the onset of uveitis and the remaining 4 exhibited retinal vasculitis 1-15 years after the onset of uveitis. Vascular occlusions occurred in 4 patients and subsequent neovascularizations developed in 3. Three patients were diagnosed with an HLA-B27-associated systemic disease. Retinal vasculitis may develop in the wake of HLA-B27-associated uveitis and might represent a rare manifestation of HLA-B27-associated disease.

Motivation is suggested as an important factor in pediatric motor rehabilitation. Therefore, we reviewed the existing evidence of (motivational) motor rehabilitation paradigms, and how motivation influences rehabilitation outcome using self-determination theory as conceptual framework. PubMed and Web-of-Science databases were systematically searched until June 2015. Data were independently extracted and critiqued for quality by three authors. Studies reporting motivational aspects were included. Most studies examined new technology (e.g., virtual reality [VR]). Out of 479 records, three RCT, six case-control, and six non-comparative studies were included with mixed quality. Motivation was rarely reported. Training individualization to the child's capabilities with more variety seemed promising to increase motivation. Motivation increased when the exercises seemed helpful for daily activities. Motivation in pediatric rehabilitation should be comprehensively assessed within a theoretical framework as there are indications that motivated children have better rehabilitation outcomes, depending on the aspect of motivation.

To evaluate the safety and efficacy of ab interno trabeculectomy (Trabectome) surgery in Chinese open angle glaucoma patients. Prospective non-comparative case series study. A total of 41 cases (34 primary open angle glaucoma patients, 3 developmental glaucoma patients and 4 pigmentary glaucoma patients) were included in the study. All the cases underwent Trabectome, including 9 cases combined with phacoemulsification cataract extraction. Major outcomes include intraocular pressure (IOP), number of glaucoma medications, secondary glaucoma surgery and postoperative complications. Criteria for successful operation were defined as IOP ≤ 21 mmHg (1 mmHg = 0.133 kPa), at least 20% IOP reduction in any two consecutive visits after 3 months with or without IOP-lowering drugs and no additional glaucoma surgery. IOP and number of glaucoma medications were compared to baseline using Wilcoxon signed-rank test with Bonferroni correction. Kaplan-Meier analysis was performed to analyze the success rate of surgery. In the all 41 patients, 21 cases (51.2%) were followed up for up to 12 months. IOP was reduced from (22.5 ± 8.1) mmHg to (17.6 ± 6.4) mmHg (P = 0.02), meanwhile number of glaucoma medications was reduced from 2.0 ± 0.9 to 1.2 ± 0.9 (P = 0.02) at 12 months. The success rate at one year was 85% and 4 cases required additional glaucoma surgery. Trabectome has many advantages, such as shorter surgery time, simple post-operative care, less intraoperative and postoperative complications and clear IOP-lowering effect. But it slong-term efficacy is still need a large sample, long-term follow-up to verify.

Minimally-invasive glaucoma surgeries (MIGS) for open angle glaucoma: A systematic review and meta-analysis

Background MIGS have been developed as a surgical alternative for glaucomatous patients. Purpose To analyze the change in intraocular pressure (IOP) and glaucoma medications using different MIGS devices (Trabectome, iStent, Excimer Laser Trabeculotomy (ELT), iStent Supra, CyPass, XEN, Hydrus, Fugo Blade, Ab interno canaloplasty, Goniscopy-assisted transluminal trabeculotomy) as a solo procedure or in association with phacoemulsification. Methods Randomized control trials (RCT) and non-RCT (non randomized comparative studies, NRS, and before-after studies) were included. Studies with at least one year of follow-up in patients affected by primary open angle glaucoma, pseudoexfoliative glaucoma or pigmentary glaucoma were considered. Risk of Bias assessment was performed using the Cochrane Risk of Bias and the ROBINS-I tools. The main outcome was the effect of MIGS devices compared to medical therapy, cataract surgery, other glaucoma surgeries and other MIGS on both IOP and use of glaucoma medications 12 months after surgery. Outcomes measures were the mean difference in the change of IOP and glaucoma medication compared to baseline at one and two years and all ocular adverse events. The current meta-analysis is registered on PROSPERO (reference n° CRD42016037280). Results Over a total of 3,069 studies, nine RCT and 21 case series with a total of 2.928 eyes were included. Main concerns about risk of bias in RCTs were lack of blinding, allocation concealment and attrition bias while in non-RCTs they were represented by patients’ selection, masking of participants and co-intervention management. Limited evidence was found based on both RCTs and non RCTs that compared MIGS surgery with medical therapy or other MIGS. In before-after series, MIGS surgery seemed effective in lowering both IOP and glaucoma drug use. MIGS showed a good safety profile: IOP spikes were the most frequent complications and no cases of infection or BCVA loss due to glaucoma were reported. Conclusions Although MIGS seem efficient in the reduction of the IOP and glaucoma medication and show good safety profile, this evidence is mainly derived from non-comparative studies and further, good quality RCTs are warranted.

To study the natural history and growth of optic nerve sheath meningiomas and evaluate their management outcome. Clinicopathologic retrospective noncomparative case series. A retrospective study of 88 patients who were treated between 1976 and 1999 at the University of British Columbia and the University of Amsterdam. Clinical reports, imaging studies, and histopathologic findings were reviewed. The mean age at onset of symptoms was 40.3 years, and most were seen in middle-aged females. Patients typically presented with visual loss, frequently associated with optic atrophy or papilledema and occasionally optociliary shunt vessels. On imaging, the optic nerve demonstrated segmental or diffuse thickening of the sheath or globular growth. Calcification was seen in 31% of cases and was associated with slower tumor growth. Tumors with posterior components in the orbit had more frequent intracranial involvement. Intracranial extension was more frequent and had a greater growth rate in younger patients. Irregular margins in the orbit implied local invasion. A presenting visual acuity better than 20/50 correlated with longer preservation of vision. Patients who underwent radiotherapy showed improvement in their visual acuity, and tumor growth was halted. Optic sheath decompression did not preserve vision. En bloc tumor excision was associated with no detectable recurrence in contrast to debulked tumors that recurred. Meningiomas show characteristic indolent growth. Management therefore should be conservative in most cases. Radiotherapy is indicated in patients with progressive visual deterioration. Surgery, when indicated, should be an en bloc excision.

We made an open, noncomparative evaluation of ofloxacin, 400 mg orally bid for 10 days, in 98 subjects with community-acquired pneumonia or pathogen-confirmed bronchitis. Thirty-nine (40%) of the subjects were treated in the hospital and 59 (60%) were treated as outpatients. The mean age of those treated was 56.2 years; 73 (74%) of the subjects either were more than 60 years old or had a history of chronic obstructive pulmonary disease, or both. There were 95 organisms initially isolated in sputum, aspirate, or lavage fluid; all were susceptible to ofloxacin, and none acquired resistance during therapy. Haemophilus influenzae was the most common pathogen (19 isolates), followed by Streptococcus pneumoniae (18) and Staphylococcus aureus (10). Clinical responses included cure in 70 patients (71%), improvement in 26 (27%), and failure in two (2%). After 10 days of therapy, pathogens persisted in two cases; in one case, Streptococcus salivarius was isolated, though it remained susceptible to ofloxacin, and in the other, Klebsiella pneumoniae was accompanied by superinfection due to a resistant strain of Serratia marcescens. We included in this study three confirmed cases of atypical pneumonia successfully treated with ofloxacin, two of them due to Mycoplasma pneumonia and one to Legionella pneumophila. Ofloxacin was well tolerated. Our data indicate that ofloxacin is effective and safe as specific and empiric treatment for many lower respiratory tract infections.

Objectives To assess the effects of treatments for non-metastatic invasive squamous cell carcinoma (SCC) of the skin using evidence from observational studies, given the paucity of evidence from randomised controlled trials. Design Systematic review of observational studies. Data sources Medline, Embase, to December 2012. Review methods Observational studies of interventions for primary, non-metastatic, invasive, SCC of the skin that reported recurrence during follow-up, quality of life, initial response to treatment, adverse events, cosmetic appearance, or death from disease. Studies were excluded if data for primary cutaneous SCC was not separable from other data. Data were extracted independently by two reviewers. Meta-analysis was performed where appropriate using a random effects model to estimate the pooled proportion of an event with 95% confidence intervals. Results 118 publications were included, covering seven treatment modalities. Pooled estimates of recurrence of SCCs were lowest after cryotherapy (0.8% (95% confidence interval 0.1% to 2%)) and curettage and electrodesiccation (1.7% (0.5% to 3.4%)), but most treated SCCs were small, low risk lesions. After Mohs micrographic surgery, the pooled estimate of local recurrence during variable follow-up periods from 10 studies was 3.0% (2.2% to 3.9%), which was non-significantly lower than the pooled average local recurrence of 5.4% (2.5% to 9.1%) after standard surgical excision (12 studies), and 6.4% (3.0% to 11.0%) after external radiotherapy (7 studies). After an apparently successful initial response of SCCs to photodynamic therapy, pooled average recurrence of 26.4% (12.3% to 43.7%; 8 studies) was significantly higher than other treatments. Evidence was limited for laser treatment (1 study) and for topical and systemic treatments (mostly single case reports or small non-comparative series with limited follow-up). Conclusions Many observational studies have looked at different treatment modalities for SCC, but the evidence base for the effectiveness of these interventions is poor. Comparison of outcomes after different treatments should be interpreted cautiously owing to biases inherent in the types of study included, and lack of direct comparisons to enable the estimation of relative treatment effect. Further evidence is needed to develop a prognostic model and stratify individuals at high risk of developing SCC, to improve the evidence base for this common cancer and to optimise clinical management.

To present visual and functional results following implantation of iris prosthesis combined with cataract surgery in eyes with previous iridocyclectomy for iris melanoma or presumed iris melanoma. Retrospective noncomparative case series. Sixteen patients (16 eyes) with iris defects after iridocyclectomy for iris melanoma in 15 cases and iris adenoma in 1 case underwent prosthetic iris device implantation surgery. Prosthetic iris implantation was combined with phacoemulsification and intraocular lens (IOL) implantation. The visual acuity, subjective glare and photophobia reduction, anatomic outcome, and complications were reviewed. Best-corrected visual acuity was improved in 13 eyes (81.25%), remained stable in 2 eyes (12.25%), and decreased in 1 eye (6.25%). Photophobia and glare improved in every case except for 1 (93.75%). Notably, after surgery 12 patients (75.00%) reported no photophobia and 10 patients (62.50%) reported no glare. The median postoperative follow-up was 29.5 months, with a minimum of 5 months and a maximum of 189 months. All iris devices were in the correct position, and all eyes achieved the desired anatomic result. The IOL optic edges were covered in all areas by either residual iris or opaque portions of a prosthetic iris device. In patients who have undergone previous iridocyclectomy for presumed iris melanoma, combined cataract surgery and iris prosthesis placement, with or without iris reconstruction, can lead to visual improvement as well as reduction of both glare and photophobia.

We evaluated the incidence, risk factors and consequences of wound infection (WI) following major head and neck cancer surgery in an open non-comparative study. The study group, comprising 95 patients who underwent clean-contaminated procedures with opening of the upper aerodigestive tract for biopsy-proven squamous cell cancer, were studied over a 1-year period. Antibiotic prophylaxis was amoxicillin and clavulanic acid. More than 20 variables were prospectively recorded for each patient. The mean follow-up was 30 months. The overall WI rate was 50.5% (48/95). Most pathogens isolated from samples were gram-negative rods. In univariate analysis, we found three risk factors for WI: alcohol consumption (P = 0.07), a hypopharyngeal location (P = 0.02) and laryngectomy stoma (P = 0.01). WI were associated with postoperative fever (P = l.5 x 10(-11)), postoperative antibiotic therapy (P = 1.5 x 10(-5)) and postoperative death (P = 0.043). Patients without WI had a median postoperative hospital stay of 15 days compared with 29 days for those with WI (P < 0.001). Healing of WI was achieved after a median time of 48 days. WI delayed postoperative radiation therapy in 21 out of 33 evaluable patients. But overall survival, and local and metastatic failures were similar with and without WI. WI are associated with a heavy postoperative morbidity, but have no prognostic impact on cancer control.

The hubris hypothesis: you can self-enhance, but you'd better not show it.

We tested whether and why observers dislike individuals who convey self-superiority through blatant social comparison (the hubris hypothesis). Participants read self-superiority claims ("I am better than others"; Experiments 1-7), noncomparative positive claims ("I am good"; Experiments 1-2, 4), self-equality claims ("I am as good as others"; Experiments 3-4, 6), temporally comparative self-superiority claims ("I am better than I used to be"; Experiment 5), other-superiority claims ("S/he is better than others"; Experiment 6), and self-superiority claims accompanied by persistent disclaimers (Experiment 7). They judged the claim and the claimant (Experiments 1-7) and made inferences about the claimant's self-view and view of others (Experiments 4-7) as well as the claimant's probable view of them (Experiment 7). Self-superiority claims elicited unfavorable evaluations relative to all other claims. Evaluation unfavorability was accounted for by the perception that the claimant implied a negative view of others (Experiments 4-6) and particularly of the observer (Experiment 7). Supporting the hubris hypothesis, participants disliked individuals who communicated self-superiority beliefs in an explicitly comparative manner. Self-superiority beliefs may provoke undesirable interpersonal consequences when they are explicitly communicated to others but not when they are disguised as noncomparative positive self-claims or self-improvement claims. © 2011 The Authors.

Toxoplasmosis is the most common cause of posterior uveitis in the world. This study described the clinical characteristics and visual outcome of 193 patients with ocular toxoplasmosis at Feiz Hospital (Isfahan, Iran) during the last six years. The setting and design used was a retrospective non-comparative observational case series. In this study, 193 patients with ocular toxoplasmosis (111 female, 82 male) were enrolled. The distribution of symptoms and fundoscopic findings were studied. The most-reported chief complaint was blurred vision in 96 % (184 patients) and floaters in 13.47 % (25 patients) of cases and most frequent clinical manifestations were chorioretinitis 98.48 % (190 patients), macular scars 50.7 % (98 patients), and atrophic optic papilla two (1.03 %) patients. Primary retinal lesions were observed in 16 (8.2 %) and combination of active lesions and old retinochoroidal scars in 177 (91.7 %) of the patients. Retinal detachment occurred in 11 (5.69 %) patients. Bilateral involvement was found in 27 % of patients. Blindness was 0.05 % after treatment. Recurrence rate was 14.5 %. In conclusion, ocular toxoplasmosis substantially varies among patients with different age, gender, site of lesion and other factors. Suddenly blurred vision, floater, and pain could be caused by Toxoplasma gondii. Flashing, may necessitate a more precise peripheral fundus examination.

A new fibrinogen concentrate Clottafact ® was developed according to European guidelines on plasma-derived products. A post-authorization safety study was set up in 2009 as part of the risk management plan. This was a non-interventional, prospective, non-comparative, multicenter study of the use of fibrinogen concentrate for congenital afibrinogenemia in real-life medical practice in France. The analysis was descriptive and performed on 3 subgroups: prophylaxis vs. on-demand treatment, age (<6, <12 and ≥12) and severity of the deficiency. Fourteen patients [1-78 years] were included in 7 centres and followed for 1 year. Twenty-one adverse drug reactions (ADRs) classically reported with fibrinogen (pallor, chills, cough, vomiting, headache, urticaria and erythematous rash) were reported in 5 of 14 patients. Two ADRs were serious: an anaphylactic shock and a subclavian venous thrombosis with a favourable outcome without sequelae. In the nine patients under prophylaxis, 365 of 367 infusions were considered as successful (99·5%) and 2 as failures. For the five patients treated on-demand, the efficacy was rated as excellent for 27 of 48 infusions and good for the 21 others. This study confirms that the benefit/risk balance for this fibrinogen concentrate is favourable. © 2016 International Society of Blood Transfusion.

To introduce and assess the results of a long-term follow-up of a one-snip punctoplasty with monocanalicular stent (Mini Monoka) for acquired external punctal stenosis (AEPS) with and without associated internal punctal and canalicular stenosis. Prospective non-comparative interventional case series. Thirty-five eligible patients (53 eyes) with AEPS underwent a horizontal one-snip punctoplasty and Mini Monoka tube insertion by or under supervision of a consultant Oculoplastic surgeon from June 1999 to May 2002. Diagnostic probing and irrigation were performed before operation and after operation at the last follow-up. Patients with canalicular obstruction, nasolacrimal duct stenosis and obstruction, and those with less than 6 months' follow-up were excluded. The Chi-square (X(2)), Fisher's exact, Pearson correlation, and multiple logistic regression analysis tests, with 95% confidence interval when appropriate, were used for statistical analysis. The age range was 39 to 90 years (mean: 67.2, SD: 11.8, SE: 2). Twenty-seven patients (77.1%) were female. There was a normal canalicular system in 21 (39.6%), lower canalicular stenosis in 10 (18.8%), and internal punctal stenosis in 22 (41.5%) eyes. Postoperative follow-up was from 6 to 41 months (mean: 18.5, SD: 9.2, SE: 1.2). There was a 77.4% complete functional success, 7.5% partial functional success, and 96.2% anatomical success at the last follow-up. The success rate was not significantly different between the eyes with and without preoperative internal punctal and canalicular stenosis (p = 0.4). The lower success rate was significantly correlated with a final abnormal probing and irrigation (p < 0.01). The use of a monocanalicular Mini Monoka stent together with a one-snip punctoplasty is helpful to prevent the recurrence of punctal stenosis in the healing phase and addresses the associated internal punctal and canalicular stenosis.

To evaluate the efficacy and safety of the ultrasonic circular cyclocoagulation procedure in patients with open-angle glaucoma naïve of previous filtering surgery. Prospective non-comparative interventional clinical study conducted in five French University Hospitals. Thirty eyes of 30 patients with open-angle glaucoma, intra-ocular pressure (IOP) > 21 mmHg and with no previous filtering glaucoma surgeries were sonicated with a probe comprising six piezoelectric transducers. The six transducers were activated with a 6-s exposure time. Complete ophthalmic examinations were performed before the procedure and at 1 day, 1 week, 1, 2, 3, 6 and 12 months after the procedure. Primary outcomes were qualified surgical success (defined as IOP reduction from baseline ≥20% and IOP > 5 mmHg with possible re-intervention and without hypotensive medication adjunction) and complete surgical success (defined as IOP reduction from baseline ≥20%, IOP > 5 mmHg and IOP < 21 mmHg with possible re-intervention and without hypotensive medication adjunction) at the last follow-up visit and vision-threatening complications. Secondary outcomes were mean IOP at each follow-up visit compared with baseline, medication use, complications and re-interventions. Intra-ocular pressure was significantly reduced (p < 0.05) from a mean pre-operative value of 28.2 ± 7.2 mmHg (n = 3.6 hypotensive medications) to 19.6 ± 7.9 mmHg at 12 months (n = 3.1 hypotensive medications and n = 1.1 procedures) (mean IOP reduction of 30%). Qualified success was achieved in 63% of eyes (19/30) (mean IOP reduction of 37% in these eyes) and complete success in 46.7% of eyes (14/30) (mean IOP reduction of 37% in these eyes) at the last follow-up. No major intra- or post-operative complications occurred. The UC(3) procedure seems to be an effective and well-tolerated method to reduce IOP in patients with open-angle glaucoma without previous filtering surgery. © 2015 Acta Ophthalmologica Scandinavica Foundation.

To report sight-threatening complications following extensive bulbar conjunctival resection and postoperative mitomycin C therapy for cosmetic eye-whitening in the United States. Retrospective noncomparative case series. Multicenter report of 9 patients referred for evaluation and management of complications following bilateral cosmetic eye whitening. Seventeen eyes of 9 patients underwent cosmetic eye-whitening performed between 2 and 48 months prior to referral to one of the centers. Sixteen of the 17 eyes had persistent conjunctival epithelial defects, with 10 eyes requiring amniotic membrane grafting to facilitate re-epithelialization. Four eyes of 2 patients developed limbal stem cell compromise confirmed with in vivo confocal laser scanning microscopy. One patient developed infectious scleritis and diplopia resulting from Tenon capsule scarring. Another patient developed scleral necrosis, secondary infectious scleritis, and infectious endophthalmitis. This patient subsequently developed noninfectious scleritis that required 3-drug-regimen immunosuppression. Severe adverse effects can occur after extensive cosmetic conjunctival resection followed by topical mitomycin C application. Patients and physicians should be aware of the potential sight-threatening complications associated with this eye-whitening procedure. Published by Elsevier Inc.

To estimate the 6-month cumulative probability of pregnancy, short-term adverse effects, and acceptability of cellulose sulfate vaginal contraceptive gel. Two hundred fertile heterosexual couples were enrolled in this single-center, phase II, 6-month noncomparative study conducted at the California Family Health Council in Los Angeles, California. Couples did not desire pregnancy, were at low risk for sexually transmitted diseases, and agreed to use 3.5 mL of cellulose sulfate gel intravaginally before each coital act as their primary means of contraception. Scheduled follow-up visits took place after one menstrual cycle and at study completion, which occurred after 6 months and six menstrual cycles had elapsed. In addition, participants were instructed to call the site at the onset of each menses to review their diary cards. The cumulative probabilities of pregnancy during 6 months and six cycles of typical use were 13.4% (95% confidence interval [CI] 7.5-19.4%) and 13.9% (95% CI 7.7-20.2%), respectively, and during 6 cycles of correct and consistent ("perfect") use: 3.9% (95% CI 0.0-9.2%). Slightly over one fourth of the women and one man reported experiencing gel-related adverse events, two thirds of which were mild and only possibly related to the gel. Three quarters of women and men reported that they would buy cellulose sulfate gel for contraception. Cellulose sulfate vaginal gel yields pregnancy rates comparable to nonoxynol-9 and few adverse events among couples at low risk for sexually transmitted diseases.

CRITICA: coding region identification tool invoking comparative analysis

Gene recognition is essential to understanding existing and future DNA sequence data. CRITICA (Coding Region Identification Tool Invoking Comparative Analysis) is a suite of programs for identifying likely protein-coding sequences in DNA by combining comparative analysis of DNA sequences with more common noncomparative methods. In the comparative component of the analysis, regions of DNA are aligned with related sequences from the DNA databases; if the translation of the aligned sequences has greater amino acid identity than expected for the observed percentage nucleotide identity, this is interpreted as evidence for coding. CRITICA also incorporates noncomparative information derived from the relative frequencies of hexanucleotides in coding frames versus other contexts (i.e., dicodon bias). The dicodon usage information is derived by iterative analysis of the data, such that CRITICA is not dependent on the existence or accuracy of coding sequence annotations in the databases. This independence makes the method particularly well suited for the analysis of novel genomes. CRITICA was tested by analyzing the available Salmonella typhimurium DNA sequences. Its predictions were compared with the DNA sequence annotations and with the predictions of GenMark. CRITICA proved to be more accurate than GenMark, and moreover, many of its predictions that would seem to be errors instead reflect problems in the sequence databases.

Electronic cigarette (EC) use is growing dramatically with use highest among young adults and current smokers. One of the most common reasons for using ECs is interest in quitting or reducing cigarettes per day (CPD); however there are few randomized controlled trials (RCT) on the effect of ECs on smoking abstinence and reduction. We conducted a two-arm; double-blind RCT. Subjects were randomized to receive 3-weeks of either disposable 4.5% nicotine EC (intervention) or placebo EC. The primary outcome was self-reported reduction of at least 50% in the number of CPDs smoked at week 3 (end of treatment) compared to baseline. Study subjects (n = 99) were young adult (21-35), current smokers (smoked ≥ 10 CPDs) living in NYC. Compared with baseline, a significant reduction in CPDs was observed at both study time periods (1 and 3 weeks) for intervention (P < .001) and placebo (P < .001) groups. Between-group analyses showed significantly fewer CPDs in the intervention group compared to the placebo group at week 3 (P = .03), but not at any other follow-up periods. The logistic regression analysis showed that using a greater number of ECs, treatment condition and higher baseline readiness to quit were significantly associated with achieving at least 50% reduction in CPDs at the end of treatment. A diverse young adult sample of current everyday smokers, who were not ready to quit, was able to reduce smoking with the help of ECs. Further study is needed to establish the role of both placebo and nicotine containing ECs in increasing both reduction and subsequent cessation. Despite the critical need for well-designed clinical trials on the effect of ECs on cessation and cigarette reduction, the majority of studies have been observational or noncomparative intervention designs. Only three RCTs studying ECs as a cessation or reduction intervention have been published, and none were conducted in the United States. The current study adds knowledge to current literature on the feasibility of using ECs to aid smoking reduction among young smokers in US urban populations. © The Author 2016.

To perform a 12 month follow-up study to assess the safety and effectiveness of resection and conjunctival autograft fixed with Tissucol® in selected cases of large pterygium. The orientation of the graft was adapted to the morphology of the scleral bed for a better coverage free of traction, with limbal position being lost. A prospective, non-comparative study of 10 cases of grade II or superior pterygium (7 primary, 3 recurrent) with at least 8mm of limbal extension. A wide scleral bed was obtained after pterygium and Tenon resection, with larger grafts being required to cover the defects. A superior conjunctival autograft was harvested and fixed to bare sclera using Tissucol. The orientation was adapted to the morphology of the scleral bed and limbal position was lost. Patients were periodically assessed for recurrence and complications for a period of 12 months. Minor complications occurred in 4 eyes. In one case a buttonhole was formed during dissection of the graft. Two presented with small limbal dehiscence, but epithelialisation was completed in the first week. In a third case, it was necessary to increase topical corticosteroids for pyogenic granuloma on the donor site, with secondary increased intraocular pressure (IOP). There were no recurrences after 12 months follow-up. A conjunctival graft of appropriate size adapted to the morphology of the scleral bed to ensure good coverage free of tension, provides good surgical results in selected cases of pterygium, regardless of the conservation the limbal orientation, with no recurrences after one year follow-up.

To assess the adequacy of 5 controlled medical terminologies (International Classification of Diseases 9, Clinical Modification [ICD9-CM]; Current Procedural Terminology 4 [CPT-4]; Systematized Nomenclature of Medicine, Clinical Terms [SNOMED-CT]; Logical Identifiers, Names, and Codes [LOINC]; Medical Entities Dictionary [MED]) for representing concepts in ophthalmology. Noncomparative case series. Twenty complete ophthalmology case presentations were sequentially selected from a publicly available ophthalmology journal. Each of the 20 cases was parsed into discrete concepts, and each concept was classified along 2 axes: (1) diagnosis, finding, or procedure and (2) ophthalmic or medical concept. Electronic or paper browsers were used to assign a code for every concept in each of the 5 terminologies. Adequacy of assignment for each concept was scored on a 3-point scale. Findings from all 20 case presentations were combined and compared based on a coverage score, which was the average score for all concepts in that terminology. Adequacy of assignment for concepts in each terminology, based on a 3-point Likert scale (0, no match; 1, partial match; 2, complete match). Cases were parsed into 1603 concepts. SNOMED-CT had the highest mean overall coverage score (1.625+/-0.667), followed by MED (0.974+/-0.764), LOINC (0.781+/-0.929), ICD9-CM (0.280+/-0.619), and CPT-4 (0.082+/-0.337). SNOMED-CT also had higher coverage scores than any of the other terminologies for concepts in the diagnosis, finding, and procedure categories. Average coverage scores for ophthalmic concepts were lower than those for medical concepts. Controlled terminologies are required for electronic representation of ophthalmology data. SNOMED-CT had significantly higher content coverage than any other terminology in this study.

AIM To describe clinical findings and complications from cases of traumatic lens subluxation/dislocation in patients with secondary glaucoma, and discuss the multiple treating methods of operation combined with primary intraocular lens (IOL) implantation. METHODS Non-comparative retrospective observational case series. Participants: 30 cases (30 eyes) of lens subluxation/dislocation in patients with secondary glaucoma were investigated which accepted the surgical treatment by author in the Ophthalmology of Xi'an No.4 Hospital from 2007 to 2011. According to the different situations of lens subluxation/dislocation, various surgical procedures were performed such as crystalline lens phacoemulsification, crystalline lens phacoemulsification combined anterior vitrectomy, intracapsular cataract extraction combined anterior vitrectomy, lensectomy combined anterior vitrectomy though peripheral transparent cornea incision, pars plana lensectomy combined pars plana vitrectomy, and intravitreal cavity crystalline lens phacofragmentation combined pars plana vitrectomy. And whether to implement trabeculectomy depended on the different situations of secondary glaucoma. The posterior chamber intraocular lenses (PC-IOLs) were implanted in the capsular-bag or trassclerally sutured in the sulus decided by whether the capsular were present. Main outcome measures: visual acuity, intraocular pressure, the situation of intraocular lens and complications after the operations. RESULTS The follow-up time was 11-36mo (21.4±7.13). Postoperative visual acuity of all eyes were improved; 28 cases maintained IOP below 21 mm Hg; 2 cases had slightly IOL subluxation, 4 cases had slightly tilted lens optical area; 1 case had postoperative choroidal detachment; 4 cases had postoperative corneal edema more than 1wk, but eventually recovered transparent; 2 cases had mild postoperative vitreous hemorrhage, and absorbed 4wk later. There was no postoperative retinal detachment, IOL dislocation, and endophthalmitis. CONCLUSION To take early treatment of traumatic lens subluxation/dislocation in patients with secondary glaucoma by individual surgical plan based on the different eye conditions would be safe and effective, which can effectively control the intraocular pressure and restore some vision.

Hypothesis: discrepancy between intra- and interpopulation studies of the relationship between dietary salt and blood pressure: fact or fiction?

PubMed

Omvik, P

1984-01-01

It is a paradox that intra-population studies fail to show significant correlation between sodium excretion and blood pressure while a clear relationship exists in cross-cultural studies. Since daily variation of sodium excretion is high, the discrepancy between the two observations could be due to non-comparable data on sodium excretion. This is a discussion of the hypothesis that the finding of a significant correlation or not between sodium excretion and blood pressure depends on the statistical analysis of the data.

Raising the suborbicularis oculi fat (SOOF): its role in chronic facial palsy

PubMed Central

Olver, J.

2000-01-01

AIMS—To determine the adjuvant role of unilateral suborbicularis oculi fat (SOOF) lift in the periorbital rehabilitation of patients with chronic facial palsy.
METHODS—In a non-comparative prospective case series nine adult patients (seven male, two female) aged 34-90 years (mean 60.5) with chronic unrecovered facial palsy (over 1 year), who had not had any previous rehabilitative periorbital surgery, were studied. Lateral tarsal strip and adjuvant transconjunctival approach subperiosteal SOOF lift under local or general anaesthesia were performed; medial canthoplasty was performed where indicated. There was clinical observation of the long term (over 1 year) effect on the ptotic palpebral-malar sulcus and lower eyelid retraction.
RESULTS—The patients were followed up for 12-24 months (mean 16). Seven patients (77%) had sustained clinical reduction of palpebral-malar sulcus ptosis. All patients had sustained reduction of lagophthalmos. Early postoperative complications included conjunctival cheimosis in 77%. Three patients with persistent keratitis required further surgical procedures on their upper eyelid to reduce the palpebral aperture. There were no cases of infraorbital nerve anaesthesia or recurrent lower eyelid retraction.
CONCLUSIONS—The SOOF lift has an adjuvant role in chronic facial palsy with lower eyelid retraction and ptotic-palpebral malar sulcus. It supports the lower eyelid elevation and tightening achieved with the lateral tarsal strip. The best results were obtained in congenital facial palsy.

To report the long-term follow-up results of intraocular foreign body (IOFB) removal at Walter Reed Army Medical Center during Operation Iraqi Freedom and Operation Enduring Freedom from February 2003 through November 2005 and to determine the prognostic factors for visual outcome in this patient population. Retrospective, noncomparative, interventional case series. Seventy-nine eyes of 70 United States military soldiers deployed in support of operations Iraqi Freedom and Enduring Freedom sustained IOFB injuries and subsequently were treated at the Walter Reed Army Medical Center with a minimum of 6 months of follow-up. The principal procedure performed was 20-gauge 3-port vitrectomy with IOFB removal through limbal or pars plana incision. Final visual acuity, rate of proliferative vitreoretinopathy, rate of endophthalmitis. Average patient age was 27 years, with an average of 331 days of postoperative follow-up. Average IOFB size was 3.7 mm (range, 0.1-20 mm). Median time to IOFB removal was 21 days (mean, 38 days; range, 2-661 days). Mean preoperative visual acuity was 20/400 (1.36 logarithm of mean angle of resolution [logMAR] units) and mean final visual acuity was 20/120 (0.75 logMAR). Of the patients, 53.4% achieved visual acuity of 20/40 or better, whereas 77.5% achieved visual acuity of better than 20/200. There were no cases of endophthalmitis (0/79 eyes; 95% confidence interval, 0%-3.1%), siderosis bulbi, or sympathetic ophthalmia. Among the eyes, 10.3% evolved to no light perception or had been enucleated by the 6-month follow-up visit. Poor visual outcome correlated with extensive intraocular injury (P<0.032). Seventeen of 79 eyes (21%) experienced proliferative vitreoretinopathy. Proliferative vitreoretinopathy correlated with poor initial vision (hand movements or worse; P = 0.035) and extensive intraocular injury (P<0.001). Timing of vitrectomy did not correlate with visual outcome. The most common systemic antibiotic administered was levofloxacin, whereas the most common topical antibiotic administered was moxifloxacin. Poor visual outcome and postoperative complication rates are related to extensive intraocular injury. Delayed IOFB removal with a combination of systemic and topical antibiotic coverage can result in good visual outcome without an apparent increased risk of endophthalmitis or other deleterious side effects.

To investigate the short-term adverse effects of using rebamipide for the treatment of dry eye by assessing visual function and optical quality. This interventional noncomparative study included 14 right eyes of 14 healthy volunteers. Serial measurements of visual acuity (VA) and higher-order aberrations were obtained prior to instillation of the rebamipide suspension (baseline) and immediately after and at 5, 10, 20, and 30 min after instillation. Functional VA measurement was performed over a 60-s period with the subject blinking naturally. Ocular aberrations were measured for 10 s while the subject was told not to blink, but no topical anesthesia was applied. Each patient also filled out a questionnaire exploring the rebamipide-associated adverse effects. There was no significant difference between functional VA measured at baseline and at each time point after the instillation of rebamipide. In contrast, the root mean square of third-order and total higher-order aberrations increased significantly immediately after drug instillation (P<0.05). The severity of higher-order aberrations at baseline was similar to that observed at 5, 10, 20, and 30 min after instillation (P>0.05). The transient reduction in optical quality immediately after administration of rebamipide is corrected by the patient's natural blink reflex. The adverse effects observed in this study do not outweigh the benefits of rebamipide treatment.

The aim of this study was to determine the effect of nicergoline in patients with neurotrophic keratopathy. This is a prospective, noncomparative interventional study. The study included 27 eyes of 24 patients with neurotrophic keratopathy who were unresponsive to conventional therapy. Patients were treated with 10 mg of oral nicergoline twice daily for at least 2 weeks. Slit-lamp examination, photography, corneal fluorescein dye testing, Cochet-Bonnet corneal sensitivity, and best-corrected visual acuity tests were performed before and after treatment. Tear nerve growth factor levels were measured before and after treatment. In 23 eyes (85%), epithelial defects healed completely between 7 and 30 days of treatment with nicergoline (mean, 15.6 ± 8.0 days). Epithelial defects persisted in 4 eyes (15%). The mean corneal sensitivity before and after treatment with nicergoline was 20.5 ± 8.5 and 30.2 ± 10.8 mm, respectively (P < 0.001). The best-corrected visual acuity (measured in units according to the logarithm of the minimum angle of resolution) was significantly improved from 1.1 ± 0.6 to 0.8 ± 0.6 (P < 0.001). The tear nerve growth factor levels were significantly higher ranging from 3.2 ± 0.3 to 6.2 ± 0.3 pg/mL (P < 0.001). Treatment with nicergoline helps patients with neurotrophic keratopathy in whom conventional treatment has failed.

Localizing pre-attentive auditory memory-based comparison: magnetic mismatch negativity to pitch change.

PubMed

Maess, Burkhard; Jacobsen, Thomas; Schröger, Erich; Friederici, Angela D

2007-08-15

Changes in the pitch of repetitive sounds elicit the mismatch negativity (MMN) of the event-related brain potential (ERP). There exist two alternative accounts for this index of automatic change detection: (1) A sensorial, non-comparator account according to which ERPs in oddball sequences are affected by differential refractory states of frequency-specific afferent cortical neurons. (2) A cognitive, comparator account stating that MMN reflects the outcome of a memory comparison between a neuronal model of the frequently presented standard sound with the sensory memory representation of the changed sound. Using a condition controlling for refractoriness effects, the two contributions to MMN can be disentangled. The present study used whole-head MEG to further elucidate the sensorial and cognitive contributions to frequency MMN. Results replicated ERP findings that MMN to pitch change is a compound of the activity of a sensorial, non-comparator mechanism and a cognitive, comparator mechanism which could be separated in time. The sensorial part of frequency MMN consisting of spatially dipolar patterns was maximal in the late N1 range (105-125 ms), while the cognitive part peaked in the late MMN-range (170-200 ms). Spatial principal component analyses revealed that the early part of the traditionally measured MMN (deviant minus standard) is mainly due to the sensorial mechanism while the later mainly due to the cognitive mechanism. Inverse modeling revealed sources for both MMN contributions in the gyrus temporales transversus, bilaterally. These MEG results suggest temporally distinct but spatially overlapping activities of non-comparator-based and comparator-based mechanisms of automatic frequency change detection in auditory cortex.

Optical coherence tomography angiography (OCTA) allows visualization of iris racemose hemangioma course and its relation to the normal iris microvasculature. To describe OCTA features of iris racemose hemangioma. Descriptive, noncomparative case series at a tertiary referral center (Ocular Oncology Service of Wills Eye Hospital). Patients diagnosed with unilateral iris racemose hemangioma were included in the study. Features of iris racemose hemangioma on OCTA. Four eyes of 4 patients with unilateral iris racemose hemangioma were included in the study. Mean patient age was 50 years, all patients were white, and Snellen visual acuity was 20/20 in each case. All eyes had sectoral iris racemose hemangioma without associated iris or ciliary body solid tumor on clinical examination and ultrasound biomicroscopy. By anterior segment OCT, the racemose hemangioma was partially visualized in all cases. By OCTA, the hemangioma was clearly visualized as a uniform large-caliber vascular tortuous loop with intense flow characteristics superimposed over small-caliber radial iris vessels against a background of low-signal iris stroma. The vascular course on OCTA resembled a light bulb filament (filament sign), arising from the peripheral iris (base of light bulb) and forming a tortuous loop on reaching its peak (midfilament) near the pupil (n = 3) or midzonal iris (n = 1), before returning to the peripheral iris (base of light bulb). Intravenous fluorescein angiography performed in 1 eye depicted the iris hemangioma; however, small-caliber radial iris vessels were more distinct on OCTA than intravenous fluorescein angiography. Optical coherence tomography angiography is a noninvasive vascular imaging modality that clearly depicts the looping course of iris racemose hemangioma. Optical coherence tomography angiography depicted fine details of radial iris vessels, not distinct on intravenous fluorescein angiography.

To describe the clinical features of an atypical form of viral retinitis in immunocompetent patients. This was a retrospective noncomparative case series. The charts of 8 patients diagnosed with and treated for focal posterior viral retinitis were reviewed. Clinical and demographic features were evaluated. All the patients had extensive laboratory tests, fundus fluorescein angiography, optical coherence tomography of macula, and polymerase chain reaction of vitreous. All the patients were referred to our Uveitis Service from other hospitals, as their uveitis symptoms deteriorated in spite of treatment. The mean age of 4 male and 4 female patients was 32.1 years (range, 22-42 years). The mean follow-up period was 10 months (range, 6-18 months). All of the patients had unilateral disease. Polymerase chain reaction analysis of vitreous specimen was positive for herpes simplex virus-1 in 5 patients and varicella zoster virus in 3 patients. Retinitis resolved after systemic acyclovir treatment in all patients. Viral etiology must be borne in mind in the differential diagnosis of atypical retinitis. It can be a milder form of viral retinitis like focal viral retinitis, as mentioned in this study. The prognosis of this disease is better than the other forms of necrotizing retinopathies involving a larger area of retina.

The objective of this review is to summarize and critically appraise existing evidence on the use of chart stimulated recall (CSR) and case-based discussion (CBD) as an assessment tool for medical trainees. Medline, Embase, CINAHL, PsycINFO, Educational Resources Information Centre (ERIC), Web of Science, and the Cochrane Central Register of Controlled Trials were searched for original articles on the use of CSR or CBD as an assessment method for trainees in all medical specialties. Four qualitative and three observational non-comparative studies were eligible for this review. The number of patient-chart encounters needed to achieve sufficient reliability varied across studies. None of the included studies evaluated the content validity of the tool. Both trainees and assessors expressed high level of satisfaction with the tool; however, inadequate training, different interpretation of the scoring scales and skills needed to give feedback were addressed as limitations for conducting the assessment. There is still no compelling evidence for the use of patient's chart to evaluate medical trainees in the workplace. A body of evidence that is valid, reliable, and documents the educational effect in support of the use of patients' charts to assess medical trainees is needed.

To evaluate the surgical outcomes of ocular surface reconstruction in corneal-conjunctival tumors using fibrin tissue adhesive. A prospective noncomparative study was performed between May 2013 and February 2015. Patients were submitted to routine surgical procedure for corneal-conjunctival tumor excision followed by amniotic membrane graft transplantation using fibrin tissue adhesive (Evicel®, Omrix Biopharmaceuticals Ltd., Israel). Results were assessed on the 1st, 7th, 15th and 30th postoperative days to analyze subjective complaints, adhesiveness and positioning of the graft, potential complications and recurrences. Twenty-five eyes were analyzed (male, 14). The diagnosis after the treatment was categorized as squamous cell neoplasia, dysplasia, actinic keratosis, squamous papilloma and compound melanocytic nevus. Few significant symptoms were reported, such as mild hyperemia and ocular dyscomfort. One case developed a conjunctival granuloma which regressed after topical treatment. All grafts were successful with no displacements or retraction postoperatively. There was no clinical recurrence of the tumor in a mean time of follow-up of 11 months. Fibrin tissue adhesive is safe and effective in the surgery of ocular surface tumor. In this series, sutureless amniotic membrane transplantation using fibrin glue has the potential to shorten the surgical time, mitigate inflammation postoperatively and improve patient discomfort.

Malaria remains a major public health problem, with half the world population at risk of contracting malaria. The effects of Plasmodium vivax on prosperity and longevity have been highlighted in several recent clinical case reports. The first line of vivax treatment drugs has seen no radical innovation for more than 60 years. This study introduces a subtle incremental innovation to vivax treatment: a chloroquine and primaquine co-blister. The co-blister includes a new chloroquine formulation incorporating coated tablets to mask the drug's bitter taste and user-friendly packaging containing tablets of each drug, which may improve patient adherence and facilitate the appropriate use of the drugs. This new formulation will replace the non-coated chloroquine distributed in Brazil. Patients were orally treated with 150 mg coated chloroquine tablets for 3 days: an initial 450 mg dose, followed by two 300 mg doses. The patients were treated concomitantly with two 15 mg primaquine tablets for 7-9 days, according to their weight. The primary objective of this study was to prove parasitological and clinical cure rates above 90 % by day 28. This single-arm open-label non-comparative trial was conducted according to the WHO recommended methodology for the surveillance of anti-malarial drug efficacy in the Brazilian Amazon. On day 28, the parasitological and clinical response was adequate in 98.8 % of patients (CI 95 % 93.4-100 %). The success rate on day 3 was 100 %, and the cumulative success rate by day 28 was 98.8 % (CI 95 % 91.7-99.8 %). There were no serious adverse events, with most adverse events classified as mild. The pharmacokinetic parameters of chloroquine analysed in whole blood dry spot samples showed mean (coefficient of variation) Cmax and AUC0-t values of 374.44 (0.35) and 3700.43 (0.36) ng/mL, respectively. This study reports an appropriate safety and efficacy profile of a new formulation of coated chloroquine tablets for vivax malaria treatment in the Brazilian Amazon. The cure rates meet the WHO efficacy criteria, supporting current Brazilian guidelines and the use of the formulation for vivax malaria treatment. Nevertheless, further studies should be conducted to address adherence and the effectiveness of the formulation. Trial registration RBR-77q7t3-UTN: U1111-1121-2982. Registered 10th May 2011.

The present study was a 52-week, non-comparative, open-label study of flexible dose paroxetine (20-40 mg) in 52 Japanese post-traumatic stress disorder (PTSD) patients in order to obtain clinical experience regarding efficacy and safety in regular clinical practice. Efficacy was measured using the Clinician-Administered PTSD Scale One Week Symptom Status Version (CAPS-SX). The mean change from baseline in CAPS-SX total score was -19.1, -22.8 and -32.3 at weeks 4, 12 and 52, respectively, and that in the Clinical Global Impression (CGI) Severity of Illness score was -1.1 at week 12 and -1.7 at week 52. A total of 46.9% were CGI responders at week 12, while 67.3% were improved on the CGI at week 52. Of 52 subjects who entered into the drug treatment, 25 completed the study. Only one patient withdrew from the study due to lack of efficacy. In patients who were rated as 'moderately ill' or less at baseline, the proportion of CGI responders at end-point was higher at a dose of 20 mg/day than at higher doses, whereas in patients rated as 'markedly ill' or more, it was higher at 30 and 40 mg/day, suggesting that severely ill patients could benefit from higher doses. Paroxetine appeared generally tolerated in short- and long-term use, and the safety profile in this study was consistent with international trials and other Japanese populations (i.e. patients suffering from depression, panic disorder or obsessive-compulsive disorder). Although the study was not conducted in double-blind fashion, the current findings suggest that paroxetine may contribute to clinically meaningful improvement that is maintained during long-term use and is generally well tolerated.

Nylon-reinforced silver sodium carboxymethylcellulose (AQUACEL(®) Ag BURN) dressings were developed to be pliable and conforming for the management of partial-thickness burns. This study evaluated the AQUACEL(®) Ag BURN glove for the management of hand burns. This 21-day, phase II, prospective, non-comparative study included 23 patients with partial-thickness hand burn of at least two fingers. The AQUACEL(®) Ag BURN glove was applied to one hand and could remain in place up to 21 days until clinically indicated to change the glove. Dressings were evaluated 1, 2, 4, 6, 8, 14, and 21 days after initial application. Safety was the primary study endpoint. Sixteen (70%) hand burns re-epithelialized fully over a mean of 15.6 days. Initial application was easy/very easy for 20 (87%) patients. Mean time for initial dressing application was 5.4 min. At final evaluation, most patients gave ratings of excellent/good for conformability (91%), overall glove performance (74%), and appropriateness of sizes (83%). Mean pain score from 0 (none) to 10 (worst imaginable) was 3.43 at baseline; during the study, mean scores were 1.15 at rest and 2.29 during movement. Of 61 glove removals, most (72%) were easy/very easy, and 12% had fallen off. Adverse events (wound site or elsewhere) occurred in 15 (65%) patients. Treatment-related adverse events were wound pain (17%), maceration (9%), and stiff fingers (4%). The AQUACEL(®) Ag BURN glove was well tolerated in the management of partial-thickness hand burn. Many patients used only one glove. When glove changes were required, they were usually quick and easy. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

The aim of the study was to evaluate complications of cataract surgery in eyes filled with silicone oil. This retrospective, noncomparative, consecutive case series analyzed medical files of patients with eyes filled with silicone oil undergoing cataract surgery. Phacoemulsification with posterior chamber intraocular lens implantation was conducted with or without concurrent silicone oil removal. In this study, 121 eyes of 120 patients were included. In 32 eyes (26.4%) with evident silicone oil microemulsification or silicone oil-associated open-angle glaucoma, silicone oil was removed prior to phacoemulsification through a pars plana incision and no cases of posterior capsular rupture occurred during the subsequent cataract surgery. In the remaining 89 eyes, phacoemulsification was performed with silicone oil in the vitreous cavity. In these eyes, the rate of posterior capsular rupture was 9/89 (10.1%) and the rate of silicone oil migration into the anterior chamber through an apparently intact posterior capsule was 5/89 (5.6%). In 94 eyes (77.7%), an intraocular lens was inserted into the capsular bag, in 3 eyes (2.5%) into the sulcus, and in 1 eye (0.8%) a transscleral suturing was performed. In this series, complications related to the silicone oil were not uncommon during cataract surgery. In the majority of patients without evident silicone oil microemulsification or silicone oil-associated open-angle glaucoma, cataract surgery and posterior chamber intraocular lens implantation were performed while leaving the silicone oil in place.

To examine the incidence and the etiology of corneal and corneoscleral injuries in the setting of combat ocular trauma, and to determine what effect these injuries have on overall visual impairment from combat ocular trauma. Retrospective, noncomparative, interventional case series, analyzing U.S. service members who were evacuated to the former Walter Reed Army Medical Center (WRAMC). Primary outcome measures were types of corneal injuries, length of follow-up at WRAMC, globe survival, and anatomical causes of blindness. Secondary outcome measures included surgical procedures performed, use of eye protection, source of injury, and visual outcomes. Between 2001 and 2011, there were 184 eyes of 134 patients with corneal or corneoscleral injuries. The average age was 26 years (range, 18-50); 99.3% were male, 31.9% had documented use of eye protection. The average follow-up was 428.2 days (3-2,421). There were 98 right-eye and 86 left-eye injuries. There were 169 open-globe and 15 closed-globe injuries with corneal lacerations occurring in 73 eyes with injuries to Zone I. Most injuries were attributable to an intraocular foreign body (IOFB; 48%), followed by penetrating (19.6%) and perforating (16.3%) injuries. The most common presenting visual acuity was hand motion/light perception (45.7%), yet, at the end of the study, visual acuity improved to 20/40 or better (40.8%). The majority of injuries in eyes with visual acuity worse than 20/200 involved the cornea and retina (58%). Injuries solely to the cornea accounted for only 19% of all injuries sustained. Ocular injuries in military combat have led to significant damage to ocular structures with a wide range of visual outcomes. The authors describe corneal and corneoscleral injuries in combat ocular trauma by classifying injuries by the anatomical site involved and identifying the main source of decreased visual acuity. In combat ocular trauma, corneal or corneoscleral injuries are not the sole etiology for poor vision. A cohesive approach among multiple ophthalmic subspecialties is needed when treating combat ocular trauma. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

An observational, non-comparative, prospective, surveillance study of individuals vaccinated with the MF59-adjuvanted A/H1N1 influenza vaccine, Focetria, (Novartis Vaccines & Diagnostics, Siena, Italy), was performed in Italy during the 2009 A/H1N1 influenza pandemic. This study assessed the short-term (six-week) safety profile of the investigational vaccine in real time. After vaccination (N=7943), adverse events (AE) were assessed using both active (telephone) and passive (healthcare database) follow-up in enrolled vaccinated subjects, including infants (6-23 months), pregnant women, and the immunosuppressed. The treating physicians of all subjects experiencing AEs post-vaccination were consulted for clinical information on the conditions reported. All AEs were coded according to ICD-10. A total of 1583 AEs occurred during the study, 67 (4.2%) of which were serious adverse events (SAEs). One SAE was considered to be possibly related to vaccination (transitory and ill-defined neurologic disorder experienced by a 16-year-old asthmatic male). Three adverse events of special interest (AESI) were identified (convulsions experienced by two epileptic subjects), none of which were considered to be vaccine-related. Six individuals died during the study period, in each case the cause of death was not related to vaccination (four cases of severe underlying co-morbidity, one case of psychoactive drug misuse, and one case of acute myocardial infarction). No cases of clinically relevant AEs, SAEs, or AESI were observed within a six-week period of vaccine administration. In accordance with existing clinical and post-marketing safety data, the results of this active surveillance study demonstrate a good safety profile for the MF59-adjuvanted A/H1N1 vaccine, Focetria, within the general population.

Active Surveillance (AS) is recommended for the treatment of localised prostate cancer; however this option may be under-used, at least in part because of expectations of psychological adverse events in those offered or accepting AS. (1) Determine the impact on psychological wellbeing when treated with AS (non-comparative studies). (2) Compare AS with active treatments for the impact on psychological wellbeing (comparative studies). We used the PRISMA guidelines and searched Medline, PsychInfo, EMBASE, CINHAL, Web of Science, Cochrane Library and Scopus for articles published January 2000-2014. Eligible studies reported original quantitative data on any measures of psychological wellbeing. We identified 34 eligible articles (n=12,497 individuals); 24 observational, eight RCTs, and two other interventional studies. Studies came from North America (16), Europe (14) Australia (3) and North America/Europe (1). A minority (5/34) were rated as high quality. Most (26/34) used validated instruments, whilst a substantial minority (14/34) used watchful waiting or no active treatment rather than Active Surveillance. There was modest evidence of no adverse impact on psychological wellbeing associated with Active Surveillance; and no differences in psychological wellbeing compared to active treatments. Patients can be informed that Active Surveillance involves no greater threat to their psychological wellbeing as part of the informed consent process, and clinicians need not limit access to Active Surveillance based on an expectation of adverse impacts on psychological wellbeing.

Purpose The benefit of salvage chemotherapy is modest in metastatic urothelial cancer. We conducted a randomized, noncomparative phase II study to measure the efficacy of cetuximab with or without paclitaxel in patients with previously treated urothelial cancer. Patients and Methods Patients with metastatic urothelial cancer who received one line of chemotherapy in the perioperative or metastatic setting were randomly assigned to 4-week cycles of cetuximab 250 mg/m2 with or without paclitaxel 80 mg/m2 per week. We used early progression as an indicator of futility. Either arm would close if seven of the initial 15 patients in that arm progressed at the first disease evaluation at 8 weeks. Results We enrolled 39 evaluable patients. The single-agent cetuximab arm closed after nine of the first 11 patients progressed by 8 weeks. The combination arm completed the full accrual of 28 patients, of whom 22 patients (78.5%) had visceral disease. Twelve of 28 patients had progression-free survival greater than 16 weeks. The overall response rate was 25% (95% CI, 11% to 45%; three complete responses and four partial responses). The median progression-free survival was 16.4 weeks (95% CI, 12 to 25.1 weeks), and the median overall survival was 42 weeks (95% CI, 30.4 to 78 weeks). Treatment-related grade 3 and 4 adverse events that occurred in at least two patients were rash (six cases), fatigue (five cases), and low magnesium (three cases). Conclusion Although it had limited activity as a single agent, cetuximab appears to augment the antitumor activity of paclitaxel in previously treated urothelial cancers. The cetuximab and paclitaxel combination merits additional study to establish its role in the treatment of urothelial cancers. PMID:22927525

To clarify the safety and efficacy of flow diverter (FD) treatment for blood blister-like aneurysm (BBA), we conducted a systematic review and literature analyzing perioperative and long-term clinical and angiographic outcomes. A comprehensive review of the up-to-date literature for studies with >2 patients related to FD treatment of BBAs published was performed. Random-effects meta-analysis was used to pool the following outcomes: complete occlusion, technical success, aneurysm recurrence, rebleeding, perioperative mortality, perioperative stroke, procedure-related morbidity and mortality, long-term neurological morbidity and mortality, and overall good neurological outcome. We included 15 non-comparative studies with 165 target BBAs. Complete occlusion rates were 72% (95%CI= 0.59-0.85). Recurrence occurred in 13% (95%CI= -0.04-0.29) and rebleeding in 3% (95%CI = -0.02-0.07) of patients. Procedure-related morbidity and mortality were 26% (95%CI =0.19-0.33) and 3% (95%CI= -0.01-0.07), respectively. Long-term good outcome was 83% (95% CI = 0.77-0.89). Subgroup analysis indicated that single FD strategy for BBA seemed to have a higher good outcome rate compared to overlapped FD strategy (89.9% versus 61.9%, OR=1.42, 95%CI=1.25-14.98, P=0.02). Complete occlusion rate and procedure-related morbidity rate did not see any significant difference between these two strategies. Our meta-analysis suggests that in select cases, FD can be safe and effective. Single FD strategy may result in a higher good outcome rate compared to overlapped FD strategy. Ultimately, treatment of BBA should be considered on a case-by-case basis to maximize patient benefits and limit the risk of perioperative complications. Copyright © 2018. Published by Elsevier Inc.

To evaluate the efficacy and safety of a novel surgical approach, ab interno trabeculectomy, in a combined procedure (clear corneal phacoemulsification + ab interno trabeculectomy) for the management of concurrent cataract and glaucoma with prognostic factors for filtration failure. Department of Ophthalmology, Palmanova Hospital, Udine, Italy. A prospective noncomparative case series of 11 eyes of 11 consecutive cataract patients with medically uncontrolled primary open-angle glaucoma or pseudoexfoliation glaucoma was performed. Each patient had phacoemulsification + intraocular lens implantation + ab interno trabeculectomy, which consisted of a gonioscopically controlled ab interno removal of a quadrant (3 clock hours) of the trabecular meshwork. The main outcome measures were intraocular pressure (IOP), the number of antiglaucomatous medications used, and complications. Ten patients completed a 3-year follow-up. One patient had further surgery because of poor IOP control; in this case, the last valid observation was carried forward for IOP calculation. Mean preoperative IOP and IOPs measured 1, 3, 6, 12, 24, and 36 months after surgery were 25.0, 15.8, 15.4, 15.4, 15.2, 15.0, and 15.3 (-38.56%) mm Hg respectively. The number of medications averaged 2.4 before surgery and dropped to 0.8 at the end of follow-up. No major complications occurred during the follow-up period. The new surgical procedure combining phacoemulsification with ab interno trabeculectomy can induce a clinically relevant decrease in IOP in eyes with cataract and glaucoma with poor prognosis for filtering surgery. However, a randomized controlled clinical trial with a more extended follow-up and a larger series of patients is needed to ascertain the actual effectiveness and safety of this procedure.

Pricing risk and ambiguity: the effect of perspective taking.

PubMed

Trautmann, Stefan T; Schmidt, Ulrich

2012-01-01

In the valuation of uncertain prospects, a difference is often observed between selling and buying perspectives. This paper distinguishes between risk (known probabilities) and ambiguity (unknown probabilities) in decisions under uncertainty and shows that the valuation disparity increases under ambiguity compared to risk. It is found that both the comparative versus noncomparative evaluation of risky and ambiguous prospects and the uniqueness of the valuation perspective (either seller or buyer) moderate this increase in the disparity under ambiguity. The finding is consistent with recent theoretical accounts of pricing under uncertainty. We discuss implications for market behaviour and for the ambiguity paradigm as a research tool.

To evaluate the outcomes of a 9-mm deep anterior lamellar keratoplasty (DALK) with removal of the deep stroma limited to the central 6-mm optical zone. Prospective, noncomparative, interventional case series. A total of 80 consecutive keratoconic eyes without deep stromal scarring, with at least 1 postoperative examination 1 month after complete suture removal. A standardized DALK was performed, including (1) deep trephination of the recipient bed 450 to 550 μm in depth and 9 mm in diameter; (2) pneumatic dissection; (3) debulking of approximately 80% of the anterior stroma; (4) removal of the deep stroma (bubble roof) from a central 6-mm optical zone; and (5) transplantation of a 9-mm anterior corneal lamella cut by microkeratome-assisted dissection (400-μm head) and sutured with a double running 10-0 nylon suture. Success rate and type of pneumatic dissection obtained; best spectacle-corrected visual acuity (BSCVA), refractive astigmatism (RA), and topographic astigmatism (TA), central corneal thickness (CCT) and endothelial cell density 12 months postoperatively; and intraoperative and postoperative complications. Pneumatic dissection created a "big bubble" in 67 of 80 eyes (83.7%), all of them but 1 (1.5%) being of type 1 according to the classification by Dua et al. After complete suture removal, BSCVA averaged 0.09±0.72 logarithm of the minimum angle of resolution (logMAR) and was ≥20/20 in 28 eyes (35%), ≥20/25 in 54 eyes (67.5%), and ≥20/40 in 76 eyes (95%); RA averaged 3.10±1.30 diopters (D), with 73 eyes (91%) within 4.5 D and none above 6 D; regular TA was detected in 72 eyes (90%); mean CCT was 492±62.10 μm; postoperative endothelial cell density averaged 2026±397cells/mm 2 with a mean cell loss of 11.2%. Intraoperative complications included loss of suction (n = 1) and perforation (n = 4). No conversion to penetrating keratoplasty was necessary. After surgery, double anterior chamber was observed in 2 cases (2.5%), both managed successfully by air filling of the anterior chamber. Stromal rejection was observed in 6 eyes (7.5%) and was reversed with topical steroids in all cases. In keratoconic eyes without deep stromal scars, the combination of a graft larger than conventional ones with limited removal of deep stroma can improve visual and refractive outcomes of DALK, while minimizing the rate of complications.

Balancing commercial and public interests

Furberg, Curt D; Hall, Mark A; Sevick, Mary Ann

2004-01-01

A large number of randomized clinical trials with important health outcomes are completed each year. Those with favorable findings are typically reported and published rapidly, while the publication of those with unfavorable results is often delayed or given a positive "spin." This observation applies primarily to industry-sponsored trials. Our objectives are to discuss the responsibility of pharmaceutical firms to the public with respect to timely, complete, and unbiased information from all randomized clinical trials and to propose solutions for improvements. We believe that in addition to financial obligations to their shareholders, pharmaceutical companies have social responsibilities to the public and to health care providers. However, private markets do not reward or compel optimal disclosure of drug safety or inferiority information on a voluntary basis. A problem which has not previously been identified relates to non-comparability of drugs. A case report from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) illustrates how public interests may be violated due to failure to inform about drug inferiority. The current system for dissemination of relevant medical information could be improved if all involved parties collaborated fully. However, full disclosure of trial results is unlikely when research results are unfavorable to the firm. We conclude that expanded government regulations will be required for a satisfactory solution to the problem. PMID:15239846

Purpose. The aim of this study is to propose a simple and efficient combination surgery for the management of dacryocystitis with canalicular obstruction. Methods. A retrospective noncomparative case series of dacryocystitis with canalicular obstruction has been studied. Twelve patients with dacryocystitis and canalicular obstruction underwent a conventional endoscopic endonasal dacryocystorhinostomy (EE-DCR) combined with a modified canalicular repair. Postoperative observations included slit lamp, fluorescein dye disappearance test, lacrimal syringing, lacrimal endoscopy, and nasal endoscopy. Results. After 6-18 months of postoperative follow-up, the symptoms of epiphora and mucopurulent discharge disappeared completely in 10 patients, and occasional or intermittent epiphora remained in 2 patients. All of the twelve patients showed an opened intranasal ostium and normal fluorescein dye disappearance test. Patent bicanalicular irrigation was achieved in 9 patients. One patient had a partial and the other two had a complete reobstruction by lacrimal irrigation to their repaired lower canaliculus; however, all of them had a patent lacrimal irrigation to upper canaliculus. The functional success rate for the combination surgery is 83% (10/12), and anatomical success rate is 75% (9/12). Conclusion. EE-DCR combined with modified canalicular repair is a simple and efficient method for the management of dacryocystitis with canalicular obstruction.

To evaluate the safety of implanting a 3-piece, 6.0 mm optic, foldable acrylic intraocular lens (IOL) in cases of posterior capsule rupture during phacoemulsification. Department of Ophthalmology, Ahepa Hospital, Aristotle University Medical School, and Interbalkan Medical Center, Thessaloniki, Greece. This prospective noncomparative case series included 28 eyes (28 patients) having phacoemulsification complicated by extensive posterior capsule rupture with or without vitreous loss. In all eyes, a 3-piece, 6.0 mm optic, foldable acrylic IOL (AcrySof MA60BM, Alcon) was implanted in the sulcus. Postoperative examination included best corrected visual acuity (BCVA), anterior segment biomicroscopy, IOL centralization and position, intraocular pressure (IOP), and fundus biomicroscopy. The follow-up was 6 months. The most common postoperative complications were transient corneal edema in 12 eyes and increased IOP in 11 eyes. Slight asymptomatic decentralization from the center of the pupil (1.0 to 2.0 mm) and pseudophacodonesis were observed in 5 eyes each. Friction of the IOL with the iris occurred in 1 eye. Clinically significant cystoid macular edema occurred in 3 eyes. The final BCVA was between 20/15 and 20/25 in 18 patients, 20/30 in 2, between 20/40 and 20/50 in 4, and between 20/60 and 20/200 in 4. AcrySof IOL implantation in the sulcus during phacoemulsification complicated by posterior capsule rupture preserved the advantages of small-incision surgery. The postoperative behavior and centralization of the IOLs resembled those of poly(methyl methacrylate) lenses.

To evaluate the clinical presentation of retinoblastoma in Alexandria, Egypt, correlate the timing of accurate diagnosis with the presence of advanced disease and identify causes of delayed presentation. Retrospective noncomparative single institution study reviews demographic and clinical data of all new children with retinoblastoma presenting to Alexandria Main University ocular oncology clinic (OOC) from January 2012 to June 2014. Diagnosis time was from initial parental complaint to retinoblastoma diagnosis and referral time was from retinoblastoma diagnosis to presentation to the Alexandria OCC. Delayed Diagnosis and referral were counted if >2 weeks. Advanced presentation is defined as clinical TNMH (8th edition) staging of cT2 or cT3 (international intraocular retinoblastoma classification group D or E) in at least one eye or the presence of extra-ocular disease (cT4). Seventy eyes of 47 children were eligible: 52% unilateral, 7% with family history and 96% presented with leukocorea. Sixty-four percent of children had advanced intraocular disease and none had extra-ocular disease. Delayed presentation occurred in 58% of children and was significantly associated with advanced disease in both unilaterally and bilaterally affected children (p = 0.003, 0.002 respectively). The delay in diagnosis was more in unilateral cases while the delay in referral was more in bilateral cases. The main cause of delayed presentation in unilateral retinoblastoma was misdiagnosis (30%) while parental shopping for second medical opinion (30%) was the main cause in bilateral children. Delayed diagnosis is a problem affecting retinoblastoma management. Better medical education and training, health education and earlier screening are recommended to achieve earlier diagnosis.

To evaluate the outcomes of eyelid reconstruction in patients who underwent full thickness skin grafts. A retrospective, noncomparative intervention study of patients who underwent periocular reconstruction with full thickness skin grafts between 2005 and 2011. One hundred consecutive Caucasian patients were included in the study, 54 women and 46 men. Mean follow up was 32 months. Indications for full thickness skin grafts were excision of eyelid tumors (98%) and cicatricial ectropion (2%). Site of lid defects were lower lid (60%), medial canthus (32%), upper lid (6%), and lateral canthus (2%). The skin graft donor sites were supraclavicular (44%), upper eyelid (24%), inner brachial (18%), and postauricular (14%).Early postoperative complications included lower eyelid graft contracture (1%) and partial failure (1%). Late sequelae included lower eyelid graft contracture (4%) and hypertrophic scarring (23%). Of the 23 patients with hypertrophic scar, 21 achieved good outcomes following massage with silicone gel and steroid ointment and 2 had persistent moderate lumpiness. No statistically significant association was found between graft hypertrophy and donor site or graft size. As high as 95% of all patients achieved good final eyelid position. Good color match was seen in 94% and graft hypopigmentation in 6%. An association between hypopigmentation and supraclavicular and inner brachial donor site was found to be statistically significant. Most patients (94%) achieved good eyelid position and color match. Majority (91%) of the early postoperative cicatricial sequelae can be reversed by massage, steroid ointment, and silicone gel application. Full thickness skin grafts have excellent graft survival rates and have minimal donor site morbidity.

Although pharmaceutical companies cannot make comparative claims in direct-to-consumer (DTC) ads for prescription drugs without substantial evidence, the U.S. Food and Drug Administration permits some comparisons based on labeled attributes of the drug, such as dosing. Researchers have examined comparative advertising for packaged goods; however, scant research has examined comparative DTC advertising. We conducted two studies to determine if comparative claims in DTC ads influence consumers' perceptions and recall of drug information. In Experiment 1, participants with osteoarthritis (n=1934) viewed a fictitious print or video DTC ad that had no comparative claim or made an efficacy comparison to a named or unnamed competitor. Participants who viewed print (but not video) ads with named competitors had greater efficacy and lower risk perceptions than participants who viewed unnamed competitor and noncomparative ads. In Experiment 2, participants with high cholesterol or high body mass index (n=5317) viewed a fictitious print or video DTC ad that had no comparative claim or made a comparison to a named or unnamed competitor. We varied the type of comparison (of indication, dosing, or mechanism of action) and whether the comparison was accompanied by a visual depiction. Participants who viewed print and video ads with named competitors had greater efficacy perceptions than participants who viewed unnamed competitor and noncomparative ads. Unlike Experiment 1, named competitors in print ads resulted in higher risk perceptions than unnamed competitors. In video ads, participants who saw an indication comparison had greater benefit recall than participants who saw dosing or mechanism of action comparisons. In addition, visual depictions of the comparison decreased risk recall for video ads. Overall, the results suggest that comparative claims in DTC ads could mislead consumers about a drug's efficacy and risk; therefore, caution should be used when presenting comparative claims in DTC ads.

Ceftaroline Fosamil for the Treatment of Community-Acquired Pneumonia: from FOCUS to CAPTURE.

PubMed

Carreno, Joseph J; Lodise, Thomas P

2014-12-01

Ceftaroline fosamil (ceftaroline hereafter) is the latest addition to the armamentarium for the treatment of patients with community-acquired pneumonia (CAP). It is currently approved by the Food and Drug Administration (FDA) for community-acquired bacterial pneumonia (CABP), which is a recent FDA indication that centers on individuals with documented bacterial pneumonias that arise in the community setting. The purpose of this review is to summarize and discuss the major findings from the Phase III CAP clinical trials as well as the clinical experience with ceftaroline among patients with CAP in the "Ceftaroline Assessment Program and Teflaro(®) Utilization Registry" (CAPTURE). In its two Phase III CAP trials, ceftaroline was compared to ceftriaxone among adults with radiographically confirmed CAP requiring hospitalization who were classified as Pneumonia Outcomes Research Team (PORT) risk class III or IV. Among patients with CAP, clinical success at test of cure was 84.3% vs 77.7% (difference 6.6%, 95% confidence interval [CI]: 1.6-11.8%) in those treated with ceftaroline and ceftriaxone, respectively, across the two Phase III clinical trials. Among patients with a culture-confirmed CABP, day 4 response rates were numerically higher, albeit non-significant, among patients that received ceftaroline vs. ceftriaxone (69.5% for ceftaroline vs. 59.4% for ceftriaxone, difference 10.1%, 95% CI, -0.6% to 20.6%). The efficacy of ceftaroline is supported by real-world observational data from CAPTURE for patients with both CAP and CABP. In addition, the CAPTURE program afforded an opportunity to assess the outcomes of patients who were excluded or limited in the original Phase III trials in a non-comparative fashion. These underrepresented patient populations with CAP included: patients that received prior antibiotics, patients in the ICU, patients with severe renal dysfunction, and those with methicillin-resistant Staphylococcus aureus (MRSA) isolated from respiratory or blood culture. As CAPTURE is a retrospective, non-comparator convenience sample registry, all the findings need to be interpreted with caution.

Assess changes in resource utilization, work and activity impairment, and health utility among OAB patients continuing to have urgency symptoms with tolterodine ER 4 mg and willing to try solifenacin 5/10 mg. This was an open-label, non-comparative, flexible-dosing, multicenter, 12-week study assessing the efficacy and safety of solifenacin 5/10 mg/day. Patients receiving tolterodine ER 4 mg/day for >/=4 weeks but continuing to experience residual urgency symptoms (>/=3 urgency episodes/24 h) were enrolled into the study. After a 14-day washout, patients began treatment with solifenacin 5 mg/day with dosing adjustments allowed at Weeks 4 and 8. Outcomes were assessed using the Work Productivity and Activity Impairment Questionnaire - Specific Health Problem (WPAI-SHP), Health Utilities Index (HUI), and a resource utilization questionnaire administered at Pre-Washout and Week 12. Patients (n=440) reported significantly fewer physician office visits (p<0.0001), UTIs (p<0.0001), and pads/diapers (p=0.0009) during the study period while receiving solifenacin 5/10 mg/day, compared with the Pre-Washout period when receiving tolterodine ER 4 mg/day. After 12 weeks of treatment with solifenacin 5/10 mg/day, patients reported a reduction in work time missed (p=0.0017), less impairment while working (p<0.0001), less overall work impairment (p<0.0001) and a reduction in activity impairment (p<0.0001) compared to Pre-Washout. There was no significant difference in health utility scores. Treatment-emergent adverse events were mostly anticholinergic in nature, and were mild to moderate in severity. Overall, solifenacin 5/10 mg/day improved work productivity, activity participation, and reduced medical care use in OAB patients who continued to have urgency symptoms with tolterodine ER 4 mg/day and wished to switch to solifenacin 5/10 mg. This was an open-label, non-comparative study; therefore, further research is needed to confirm these results.

A SIX-WEEK SUPERVISED EXERCISE AND EDUCATIONAL INTERVENTION AFTER TOTAL HIP ARTHROPLASTY: A CASE SERIES

PubMed Central

Madara, Kathleen; Zeni, Joseph A

2017-01-01

Background and Purpose Most rehabilitation interventions after total hip arthroplasty (THA) are not designed to return patients to high-levels of physical activity and, thus, low levels of physical activity and residual weakness are common. The purpose of this case series was to describe the feasibility and preliminary efficacy of an exercise and education intervention for patients after THA who have already completed formal outpatient physical therapy. Study Design Case series Case Description Two participants underwent unilateral THA seven (case A) or eight (case B) months prior to the intervention. Individuals participated in 18 treatment sessions that included progressive aerobic and strengthening exercises and meetings with a health coach. Change in function, strength, and self-reported physical activity were measured. Outcomes 12 months after surgery were compared to a historical cohort of patients after THA. Outcome There were no adverse events during the intervention. At the end of the intervention, hip and knee strength on the surgical side increased approximately 30% compared to baseline in both cases. Activity level, and recreational performance, including walking up stairs and hiking uphill (case A), and running and golfing (case B), improved by the end of the intervention. Most changes were maintained at follow-up, although hip strength for case B decreased 27% after discharge from the intervention. Outcomes for both cases exceeded historical averages for patients 12 months after THA, with the exception of strength in case B. Discussion The exercise intervention was well tolerated and without negative effects in two participants. Both participants increased their ability to complete demanding recreational and sports-related activities, physical activity, and demonstrated improved hip abductor and knee extensor strength. Further research is needed to evaluate the implementation and effectiveness of similar interventions after THA. Level of Evidence Level 4 PMID:28515981

To determine if (1) absorbed radiation dose and (2) fluoroscopy time decreased with experience over the first 100 cases of a single surgeon's hip arthroscopy practice. Subjects who underwent hip arthroscopy for symptomatic femoroacetabular impingement and labral injury were eligible for analysis. Inclusion criteria included the first 100 subjects who underwent hip arthroscopy by a single surgeon (December 2013 to December 2014). Subject demographics, procedure details, fluoroscopy absorbed dose (milligray [mGy]), and time were recorded. Subjects were categorized by date of surgery to one of 4 possible groups (25 per group). One-way analysis of variance was used to determine if a significant difference in dose (mGy) or time was present between groups. Simple linear regression analysis was performed to determine the relation between case number and both radiation dose and fluoroscopy time. Subjects underwent labral repair (n = 93), cam osteoplasty (n = 90), and pincer acetabuloplasty (n = 65). There was a significant (P < .001 for both) linear regression between case number and both radiation dose and fluoroscopy time. A significant difference in mGy was observed between groups, group 1 the highest and group 4 the lowest amounts of radiation (P = .003). Comparing individual groups, group 4 was found to have a significantly lower amount of radiation than group 1 (P = .002), though it was not significantly lower than that of group 2 (P = .09) or group 3 (P = .08). A significant difference in fluoroscopy time was observed between groups, group 1 the highest and group 4 the lowest times (P = .05). Comparing individual groups, group 4 was found to have a significantly lower fluoroscopy time than group 1 (P = .039). Correction for weight, height, and body mass index all revealed the same findings: significant (P < .05) differences in both dose and time across groups. The absorbed dose of radiation and fluoroscopy time decreased significantly over the first 100 cases of a single surgeon's hip arthroscopy practice learning curve.

To evaluate the effect of diquafosol tetrasodium (DQS) for the treatment of persistent dry eye after laser in situ keratomileusis (LASIK). Miyata Eye Hospital, Miyazaki, Japan. Noncomparative case series. This prospective study included 30 eyes of 15 patients in whom dry eye had persisted for over 12 months after LASIK, and the symptoms had not improved with artificial tears and sodium hyaluronate treatment. In addition, treatment with DQS 3% eye drops, 6 times a day, was performed for 12 weeks. Best-corrected visual acuity, tear secretion with the Schirmer test, tear break-up time, and fluorescein and lissamine green staining scores on the cornea and conjunctiva were examined before and at 1, 4, and 12 weeks after the addition. A subjective questionnaire of 14 symptoms was also assessed before and 12 weeks after treatment. The fluorescein and lissamine green staining scores significantly improved over 12 weeks; however, the best-corrected visual acuity and tear secretion did not change. The symptoms of fatigue, dryness, grittiness, discomfort, difficulty in reading, and discomfort within the area of dryness improved after the additional DQS treatment. The DQS treatment improved the subjective and objective symptoms of persistent dry eye after LASIK. Increased mucin production because of the addition of DQS probably improved the tear film stability and reduced the symptoms of dry eye in patients who had persistent dry eye after LASIK.

To analyze the feasibility and perioperative results of patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis. This is a mono-centric analysis of perioperative data from 48 consecutive patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis. Data include the preoperative variables, operative and postoperative course and complication rates related to bowel anastomosis. End points were time spent for anastomosis and intra- and postoperative complication rates. Median operating time was 23.0 (13-60) min for the ileoileal anastomosis. Median overall operating time was 295 (200-780) min, with a median of 282 (200-418) min and 414.0 (225-780) min for the ileum conduit (N = 35) and ileal neobladder (N = 13). Two patients developed paralytic ileus; in another patient acute peritonitis occurred, but was caused by urinary leakage and therefore unrelated to the bowel anastomosis. No anastomotic leakage was noticed. Costs for the robot-sewn anastomosis was 8€ compared to 1250€ for a stapled anastomosis which was performed in previous cases. Limitations are the non-comparative nature of the analysis and the limited number of patients. Robot-sewn ileoileal anastomosis is feasible with low complication rates. Compared to the stapled anastomosis, a robot-sewn ileoileal anastomosis may serve as an alternative and cost-saving approach.

Background: The aim of present study is to determine the long-term results of patients who undergo pars plana vitrectomy after retained nucleus into the vitreous. Setting: Service of Ophthalmology, Hospital Universitari St Joan, Reus (Barcelona), Spain. Methods: Retrospective, noncomparative, consecutive case series. Medical records were reviewed of all patients who underwent pars plana vitrectomy for retained nucleus into the vitreous after complicated cataract surgery, over a 9-year period between August 1, 1997 and July 31, 2005. Result: The incidence of retained lens fragments was 0.57% (63 patients), the postoperative visual acuity was higher than 20/40 in 59.60% and fell to 48.93% by the end of the study, and was related to the presence of CME and retinal detachment. The CME appeared in 31.91% of the patients and was related to preoperative uveitis an corneal edema. In the group of patients on whom the vitrectomy was performed at the time of cataract complication, visual acuity was higher than 20/40 in 77.77%, and no one developed secondary glaucoma or uveitis. Conclusion: Being retrospective, our study was not result conclusive. Despite the initial good results of these patients after PPV surgery, follow-up should be accurate and over a long period of time in order to minimize postoperative complications such as retinal detachment, retinal breaks, secondary glaucoma and CME.

Hashemi, Hassan; Dadgostar, Alhan

2011-06-01

To assess the visual outcome of using fibrin adhesive in automated lamellar therapeutic keratoplasty with a microkeratome in the treatment of anterior corneal opacities. In this prospective noncomparative clinical trial, surgery was done on 10 eyes belonging to 9 patients with anterior stromal opacity (macular dystrophy, spheroidal degeneration, scarring because of advanced recurrent pterygium, refractive surgery, or trauma). Depending on the depth of the opacity, a 130- or 250-μm flap was removed from the recipient cornea using a microkeratome. Then, a thin layer of fibrin adhesive was spread over the bed, and a lenticule with the same thickness, created from the donor cornea, was positioned in place. After allowing the glue to set for about 5 minutes, a bandage contact lens was placed over the cornea, which was removed 7-10 days postoperatively. All corneas healed properly, and none required suturing or reoperation. During the follow-up period, no inflammation or rejection was observed. The donor cornea and the donor-recipient interface remained clear in all cases. The mean of best contact lens-corrected visual acuity improved from 1.14 ± 0.53 to 0.51 ± 0.23 in the logarithm of the minimum angle of resolution scale. The fibrin glue can provide safe and effective attachment needed in automated lamellar therapeutic keratectomy and obviates the need for suturing. However, it requires improvement for easier and safer use in ophthalmology.

Purpose. To evaluate the effect of en bloc lateral wall decompression with additional orbital fat resection in terms of exophthalmos reduction and complications. Methods. A retrospective, noncomparative case series study from 1999 to 2011 (chart review) in Graves' orbitopathy (GO) patients. The standardized surgical technique involved removal of the lateral orbital wall including the orbital rim via a lid crease approach combined with additional orbital fat resection. Exophthalmos, diplopia, retrobulbar pressure sensation, and complications were analyzed pre- and postoperatively. Results. A total of 111 patients (164 orbits) with follow-up >3 months were analysed. Mean exophthalmos reduction was 3.05mm and preoperative orbital pressure sensation resolved or improved in all patients. Visual acuity improved significantly in patients undergoing surgery for rehabilitative or vision threatening purposes. Preoperative diplopia improved in 10 patients (9.0%) but worsened in 5 patients (4.5%), necessitating surgical correction in 3 patients. There were no significant complications; however, one patient had slight hollowing of the temporalis muscle around the scar that did not necessitate revision, and another patient with a circumscribed retraction of the scar itself underwent surgical correction. Conclusions. The study confirms the efficiency of en bloc lateral wall decompression in GO in a large series of patients, highlighting the low risk of disturbance of binocular functions and of cosmetic blemish in the temporal midface region.

To describe in detail corneal indentation (CI) in the management of a series of patients treated for acute angle closure (AAC). Retrospective, consecutive, noncomparative case series. Seven consecutive patients (8 eyes) referred to the authors with the diagnosis of AAC. Patients presented to the Prince of Wales Hospital, Randwick, or to the private practices of the authors. Seven patients (8 eyes) underwent CI as part of their early management for AAC. Reduction in intraocular pressure (IOP), symptoms of AAC and pain relief. Of the 7 patients, complete data were available for 6. The IOP was significantly reduced (P<0.05) and 3 of 4 patients with severe acute pain reported early resolution of pain after CI. The average reduction in IOP was 20.9 mmHg (range +1 to -45). All patients subsequently underwent definitive management with laser peripheral iridotomies or lensectomy using phacoemulsification. Three patients treated acutely with CI without any medical agents had a mean IOP reduction of 21 mmHg (range, 20-23) after indentation. Corneal indentation is a rapid, portable, and effective method of reducing elevated IOP in the setting of AAC. It can be performed with instrumentation that is readily at hand and allows for rapid pain relief. This reduction in IOP improves corneal clarity and permits further definitive management of the patient with AAC.

To report on a series of vascular tumors of the iris. Noncomparative case series. A retrospective medical record review of all patients with an iris vascular tumor was performed to identify the clinical features and develop a simple classification of these lesions. Included were demographics, clinical features, systemic associations, complications, management, and histopathology. There were 54 eyes in 45 patients with an iris vascular tumor. These were categorized as racemose hemangioma (41 eyes: 29 simple and 12 complex), cavernous hemangioma (3 eyes: 2 localized and 1 systemic), capillary hemangioma (1 eye, localized), varix (3 eyes, localized), and microhemangiomatosis (6 eyes, localized). The hemangiomas occurred in adults at a median age of 55 years, whereas capillary hemangioma occurred in infancy and cavernous hemangioma with systemic involvement occurred in a child. Of the 41 eyes with iris racemose hemangioma, none showed systemic involvement. Of all 54 eyes, transient hyphema was the main complication, found at some point in 30% or more of each affected eye except for iris capillary and racemose hemangioma. Surgical resection was necessary in 1 cavernous hemangioma and 1 varix. The remainder were managed with observation. There are now well-documented examples of iris racemose hemangioma, cavernous hemangioma, capillary hemangioma, varix, and microhemangiomatosis. Transient hyphema is the main complication. Observation is usually advised. Most are solitary lesions confined to the iris and some (cavernous hemangioma and microhemangiomatosis) can have important systemic associations.

To evaluate long-term results after insertion of implantable contact lenses (ICLs) in phakic eyes. Prospective, noncomparative, interventional case series. Seventy-five phakic eyes (65 myopic, 10 hyperopic eyes) of 45 patients aged 21.7 to 60.6 years were included. STAAR Collamer Implantable Contact Lenses (STAAR Surgical Inc., Nidau, Switzerland) were implanted for correction of high myopia and hyperopia. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and intraocular pressure (IOP) were determined. Presence of lens opacification and the distance between the ICL and the crystalline lens were assessed by slit-lamp examination before surgery and at 1, 3, 6 months, and yearly after lens implantation. Preoperative mean spherical equivalent was -16.23+/-5.29 diopters (D) for myopic eyes and +7.88 +/-1.46 D for hyperopic eyes. After ICL implantation, mean residual refractive error was -1.77+/-2.17 D in myopic patients and +0.44+/-0.69 D in hyperopic patients. Preoperative mean UCVA was Snellen 0.03+/-0.03 for myopic patients and Snellen 0.12+/-0.16 for hyperopic patients. Preoperative mean BCVA was Snellen 0.49+/-0.23 for myopic patients and Snellen 0.82+/-0.23 for hyperopic patients. After ICL implantation, mean UCVA up to the end of individual observation time was Snellen 0.36+/-0.36 for myopic patients and Snellen 0.58+/-0.28 for hyperopic patients. Mean BCVA was Snellen 0.73+/-0.26 for myopic and Snellen 0.80+/-0.24 for hyperopic patients. Mean preoperative IOP was 14.2+/-2.7 mmHg, and mean postoperative IOP was 13.46+/-2.1 mmHg over all follow-up investigations. The main complication was the development of subcapsular anterior opacifications of the crystalline lens in 25 eyes (33.3%), 2 of which showed direct contact to the ICL. Eleven eyes (14.7%) were stable in opacification and 14 eyes (18.7%) had progressive opacifications. The median time to opacification was 27.1 months. In 8 patients (10.7%), the subjective visual impairment mandated cataract surgery. The most significant long-term complication after ICL implantation is the formation of opacifications of the crystalline lens with the risk of the necessity of subsequent cataract surgery (10.7%). Old age, female gender, and contralateral opacification are independent significant risk factors for early formation of opacifications in this patient group.

Hospital partnerships, mergers and cooperatives are arrangements frequently seen as a means of improving health service delivery. Many of the assumptions used in planning hospital cooperatives are not stated clearly and are often based on limited or poor scientific evidence. This is a protocol for a systematic review, following the Cochrane EPOC methodology. The review aims to document, catalogue and synthesize the existing literature on the reported methods for the evaluation of hospital cooperation activities as well as methods of hospital cooperation. We will search the Database of Abstracts of Reviews of Effectiveness, the Effective Practice and Organisation of Care Register, the Cochrane Central Register of Controlled Trials and bibliographic databases including PubMed (via NLM), Web of Science, NHS EED, Business Source Premier (via EBSCO) and Global Health for publications that report on methods for evaluating hospital cooperatives, strategic partnerships, mergers, alliances, networks and related activities and methods used for such partnerships. The method proposed by the Cochrane EPOC group regarding randomized study designs, controlled clinical trials, controlled before and after studies, and interrupted time series will be followed. In addition, we will also include cohort, case-control studies, and relevant non-comparative publications such as case reports. We will categorize and analyze the review findings according to the study design employed, the study quality (low versus high quality studies) and the method reported in the primary studies. We will present the results of studies in tabular form. Overall, the systematic review aims to identify, assess and synthesize the evidence to underpin hospital cooperation activities as defined in this protocol. As a result, the review will provide an evidence base for partnerships, alliances or other fields of cooperation in a hospital setting. PROSPERO registration number: CRD42011001579.

To evaluate the efficacy and safety of a triptorelin pamoate (11.25 mg) 3-month formulation in the management of central precocious puberty (CPP) (TP Study) and to retrospectively compare it with a triptorelin acetate (11.25 mg) 3-month formulation (TA Study). We conducted two phase III, multicentre, single-stage, non-comparative, open-label studies. In the TP Study, patients with CPP received an intramuscular injection of triptorelin pamoate 11.25 mg at baseline and 3 months after baseline. Hormonal changes as well as safety and efficacy endpoints were measured at baseline, 3 months, and 6 months. The baseline characteristics of the 37 patients in the TP Study were similar to those of the TA Study population. A suppressed luteinising hormone (LH) response (LH peak ≤3 IU/l) to the gonadotrophin-releasing hormone test at 3 months (primary endpoint) occurred in 83.8 and 82.8% of the cases in the TP and the TA Study, respectively. At 6 months, a suppressed LH response occurred in 86.5 and 96.8% of the cases in the TP and the TA Study, respectively. Pubertal development was slowed in both studies. Adverse events were mild to moderate and resolved without sequelae in the TP Study. Triptorelin pamoate 11.25 mg administered at 3-month intervals is an effective and well-tolerated treatment in patients with CPP. The efficacy and safety profiles appear similar to those reported in the literature for triptorelin acetate 11.25 mg. © 2016 S. Karger AG, Basel.

Lean is a set of operating philosophies and methods that help create a maximum value for patients by reducing waste and waits. It emphasizes the consideration of the customer's needs, employee involvement and continuous improvement. Research on the application and implementation of lean principles in health care has been limited. This is a protocol for a systematic review, following the Cochrane Effective Practice and Organisation of Care (EPOC) methodology. The review aims to document, catalogue and synthesize the existing literature on the effects of lean implementation in health care settings especially the potential effects on professional practice and health care outcomes. We have developed a Medline keyword search strategy, and this focused strategy will be translated into other databases. All search strategies will be provided in the review. The method proposed by the Cochrane EPOC group regarding randomized study designs, non-randomised controlled trials controlled before and after studies and interrupted time series will be followed. In addition, we will also include cohort, case-control studies, and relevant non-comparative publications such as case reports. We will categorize and analyse the review findings according to the study design employed, the study quality (low- versus high-quality studies) and the reported types of implementation in the primary studies. We will present the results of studies in a tabular form. Overall, the systematic review aims to identify, assess and synthesize the evidence to underpin the implementation of lean activities in health care settings as defined in this protocol. As a result, the review will provide an evidence base for the effectiveness of lean and implementation methodologies reported in health care. PROSPERO CRD42014008853.

Rotator cuff tears are one of the most common conditions affecting the shoulder. Because of the difficulty in managing massive rotator cuff tears and the inability of standard techniques to prevent arthropathy, surgeons have developed several novel techniques to improve outcomes and ideally alter the natural history. To systematically review the existing literature and analyze reported outcomes to evaluate the effectiveness of using a bridging graft reconstruction technique to treat large to massive irreparable rotator cuff tears. Systematic review. A systematic search of PubMed, EMBASE, CINAHL, and CENTRAL was employed with the key terms "tear," "allograft," and "rotator cuff." Eligibility was determined by a 3-phase screening process according to the outlined inclusion/exclusion criteria. Data in relation to the primary and secondary outcomes were summarized. The results were synthesized according to the origin of the graft and the level of evidence. Fifteen studies in total were included in this review: 2 comparative studies and 13 observational case series. Both the biceps tendon and the fascia lata autograft groups had significantly superior structural integrity rates on magnetic resonance imaging at 12-month minimum follow-up when compared with their partial primary repair counterparts (58% vs 26%, P = .036; 79% vs 58%, P < .05), respectively. Multiple noncomparative case series investigating allografts, xenografts, and synthetic materials for bridging reconstruction of large to massive rotator cuff tears demonstrated high structural healing rates (74%-90%, 73%-100%, and 60%-90%, respectively). Additionally, both comparative studies and case series demonstrated a general improvement of patients' functional outcome scores. Using a graft for an anatomic bridging rotator cuff repair results in improved function on objective testing and may be functionally better than nonanatomic or partial repair of large to massive rotator cuff tears. Allograft or xenograft techniques appear to be favorable options, given demonstrated functional improvement, imaging-supported graft survival, and lack of harvest complication risk. More high-quality randomized controlled studies are needed to further assess this technique.

To provide an evidence-based summary of commercially available aqueous shunts currently used in substantial numbers (Ahmed [New World Medical, Inc., Rancho Cucamonga, CA], Baerveldt [Advanced Medical Optics, Inc., Santa Ana, CA], Krupin [Eagle Vision, Inc, Memphis, TN], Molteno [Molteno Ophthalmic Ltd., Dunedin, New Zealand]) to control intraocular pressure (IOP) in various glaucomas. Seventeen previously published randomized trials, 1 prospective nonrandomized comparative trial, 1 retrospective case-control study, 2 comprehensive literature reviews, and published English language, noncomparative case series and case reports were reviewed and graded for methodologic quality. Aqueous shunts are used primarily after failure of medical, laser, and conventional filtering surgery to treat glaucoma and have been successful in controlling IOP in a variety of glaucomas. The principal long-term complication of anterior chamber tubes is corneal endothelial failure. The most shunt-specific delayed complication is erosion of the tube through overlying conjunctiva. There is a low incidence of this occurring with all shunts currently available, and it occurs most frequently within a few millimeters of the corneoscleral junction after anterior chamber insertion. Erosion of the equatorial plate through the conjunctival surface occurs less frequently. Clinical failure of the various devices over time occurs at a rate of approximately 10% per year, which is approximately the same as the failure rate for trabeculectomy. Based on level I evidence, aqueous shunts seem to have benefits (IOP control, duration of benefit) comparable with those of trabeculectomy in the management of complex glaucomas (phakic or pseudophakic eyes after prior failed trabeculectomies). Level I evidence indicates that there are no advantages to the adjunctive use of antifibrotic agents or systemic corticosteroids with currently available shunts. Too few high-quality direct comparisons of various available shunts have been published to assess the relative efficacy or complication rates of specific devices beyond the implication that larger-surface-area explants provide more enduring and better IOP control. Long-term follow-up and comparative studies are encouraged.

A Business Case Framework for Planning Clinical Nurse Specialist-Led Interventions.

PubMed

Bartlett Ellis, Rebecca J; Embree, Jennifer L; Ellis, Kurt G

2015-01-01

The purpose of this article is to describe a business case framework that can guide clinical nurse specialists (CNS) in clinical intervention development. Increased emphasis on cost-effective interventions in healthcare requires skills in analyzing the need to make the business case, especially for resource-intensive interventions. This framework assists the CNS to anticipate resource use and then consider if the intervention makes good business sense. We describe a business case framework that can assist the CNS to fully explore the problem and determine if developing an intervention is a good investment. We describe several analyses that facilitate making the business case to include the following: problem identification and alignment with strategic priorities, needs assessment, stakeholder analysis, market analysis, intervention implementation planning, financial analysis, and outcome evaluation. The findings from these analyses can be used to develop a formal proposal to present to hospital leaders in a position to make decisions. By aligning intervention planning with organizational priorities and engaging patients in the process, interventions will be more likely to be implemented in practice and produce robust outcomes. The business case framework can be used to justify to organization decision makers the need to invest resources in new interventions that will make a difference for quality outcomes as well as the financial bottom line. This framework can be used to plan interventions that align with organizational strategic priorities, plan for associated costs and benefits, and outcome evaluation. Clinical nurse specialists are well positioned to lead clinical intervention projects that will improve the quality of patient care and be cost-effective. To do so requires skill development in making the business case.

The aim of the study was to report the incidence of retinopathy of prematurity (ROP) and severe ROP and identify the risk factors for their development in a large nursery in Kuwait. This was a retrospective, interventional, non-comparative, hospital-based study. Retrospective review of ROP records of premature babies having either birth weight of less than 1501 g or gestational age at birth of 34 weeks or less and born between January 2001 and August 2003. By univariate and multivariate logistic regression analysis. Out of the 599 babies studied, 38.9% developed ROP and 7.8% needed treatment for severe ROP. Multivariate analysis showed low birth weight (OR 13.753, 95% CI 3.66-51.54; ( P < 0.001), gestational age (OR 13.75, 95% CI 3.66-51.54; P < 0.001), surfactant (OR 1.72, 95% CI 1.04-2.83; P = 0.032) and stay in the intensive care unit for longer than 15 days (OR 2.25, 95% CI 1.05-4.85; P = 0.033) to be significant for the development of any ROP. Low birth weight (OR 22.86, 95% CI 3.86-134.82; P = 0.001), bacterial sepsis (OR 3.27, 95% CI 1.51-7.05; P = 0.002) and need for surfactant (OR 4.41, 95% CI 0.94 -20.56; P = 0.059) were found to be the risk factors for severe ROP needing laser treatment. The incidence of both any ROP and ROP needing treatment are comparable to other studies. Low birth weight is the most important risk factor for both any ROP and severe ROP.

Secondary use of electronic health record (EHR) data can reduce costs of research and quality reporting. However, EHR data must be consistent within and across organizations. Flowsheet data provide a rich source of interprofessional data and represents a high volume of documentation; however, content is not standardized. Health care organizations design and implement customized content for different care areas creating duplicative data that is noncomparable. In a prior study, 10 information models (IMs) were derived from an EHR that included 2.4 million patients. There was a need to evaluate the generalizability of the models across organizations. The pain IM was selected for evaluation and refinement because pain is a commonly occurring problem associated with high costs for pain management. The purpose of our study was to validate and further refine a pain IM from EHR flowsheet data that standardizes pain concepts, definitions, and associated value sets for assessments, goals, interventions, and outcomes. A retrospective observational study was conducted using an iterative consensus-based approach to map, analyze, and evaluate data from 10 organizations. The aggregated metadata from the EHRs of 8 large health care organizations and the design build in 2 additional organizations represented flowsheet data from 6.6 million patients, 27 million encounters, and 683 million observations. The final pain IM has 30 concepts, 4 panels (classes), and 396 value set items. Results are built on Logical Observation Identifiers Names and Codes (LOINC) pain assessment terms and extend the need for additional terms to support interoperability. The resulting pain IM is a consensus model based on actual EHR documentation in the participating health systems. The IM captures the most important concepts related to pain.

To describe the use of 25-gauge active aspiration silicon tip in removal of intraocular foreign bodies, including glass. Retrospective, noncomparative, interventional study. Eleven eyes of 11 patients who underwent the procedure between January 2013 and April 2015. The study included 10 males and 1 female with a mean age of 31.27 ± 9.64 years (range 12-45 years). All eyes in which 25-gauge active aspiration silicon tip-assisted removal of intraocular foreign body (IOFB) was done in a sutureless vitrectomy setup, irrespective of the nature of IOFB, were included. We excluded the participants with less than 6 months of postoperative follow-up. The primary outcome of the study was to assess the feasibility and reproducibility of 25-gauge active aspiration silicon tip-assisted removal of IOFB. The secondary outcome measures included change in best-corrected visual acuity (BCVA), and intraoperative and postoperative complications. There were iron (6), glass (2), wooden (1), pellet (1), and stone (1) IOFBs, for which 25-gauge active aspiration silicon tip-assisted removal was done successfully. The mean BCVA in Snellen's decimal equivalent improved significantly from 0.14 ± 0.16 to 0.34 ± 0.36 with a mean follow-up of 12 months (range 6-24 months). Intraoperatively, drop of IOFB because of loss of vacuum was observed in 2 eyes. Postoperatively, cystoid macular edema with epiretinal membrane was seen in 1 eye. There were no other intraoperative and postoperative complications. Use of 25-gauge active aspiration silicon tip to assist removal of magnetic and nonmagnetic IOFBs is a feasible and reproducible procedure, and required instrumentation is readily available in present-day vitrectomy era.

Experience with temporary intravascular shunts (TIVS) for vessel injury comes from the military sector and while the indications might be clear in geographically isolated and under resourced war zones, this may be an uncommon scenario in civilian trauma. Data supporting TIVS use in civilian trauma have been extrapolated from the military literature where it demonstrated improved life and limb salvage. Few non-comparative studies from the civilian literature have also revealed similar favorable outcomes. Still, TIVS placement in civilian vascular injuries is uncommon and by some debatable given the absence of clear indications for placement, the potential for TIVS-related complications, the widespread resources for immediate and definitive vascular repair, and the need for curtailing costs and optimizing resources. This article reviews the current evidence and the role of TIVS in contemporary civilian trauma management. PMID:28775985

Nivolumab with or without ipilimumab treatment for metastatic sarcoma (Alliance A091401): two open-label, non-comparative, randomised, phase 2 trials.

Patients with metastatic sarcoma have limited treatment options. Nivolumab and ipilimumab are monoclonal antibodies targeting PD-1 and CTLA-4, respectively. We investigated the activity and safety of nivolumab alone or in combination with ipilimumab in patients with locally advanced, unresectable, or metastatic sarcoma. We did a multicentre, open-label, non-comparative, randomised, phase 2 study that enrolled patients aged 18 years or older and had central pathology confirmation of sarcoma with at least one measurable lesion by Response Evaluation Criteria In Solid Tumors (RECIST) 1.1, evidence of metastatic, locally advanced or unresectable disease, an ECOG performance status of 0-1, and received at least one previous line of systemic therapy. Patients were assigned to treatment in an unblinded manner, as this trial was conducted as two independent, non-comparative phase 2 trials. Enrolled patients were assigned (1:1) via a dynamic allocation algorithm to intravenous nivolumab 3 mg/kg every 2 weeks, or nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 weeks for four doses. Thereafter, all patients received nivolumab monotherapy (3 mg/kg) every 2 weeks for up to 2 years. The primary endpoint was the proportion of patients with locally advanced, unresectable or metastatic soft tissue sarcoma achieving a confirmed objective response. Analysis was per protocol. This study is ongoing although enrolment is closed. It is registered with ClinicalTrials.gov, number NCT02500797. Between Aug 13, 2015, and March 17, 2016, 96 patients from 15 sites in the USA underwent central pathology review for eligibility and 85 eligible patients, including planned over-enrolment, were allocated to receive either nivolumab monotherapy (43 patients) or nivolumab plus ipilimumab (42 patients). The primary endpoint analysis was done according to protocol specifications in the first 76 eligible patients (38 patients per group). The number of confirmed responses was two (5% [92% CI 1-16] of 38 patients) in the nivolumab group and six (16% [7-30] of 38 patients) in the nivolumab plus ipilimumab group. The most common grade 3 or worse adverse events were anaemia (four [10%] patients), decreased lymphocyte count (three [7%]), and dehydration, increased lipase, pain, pleural effusion, respiratory failure, secondary benign neoplasm, and urinary tract obstruction (two [5%] patients each) among the 42 patients in the nivolumab group and anaemia (eight [19%] patients), hypotension (four [10%] patients), and pain and urinary tract infection (three [7%] patients each) among the 42 patients in the nivolumab plus ipilimumab group. Serious treatment-related adverse events occurred in eight (19%) of 42 patients receiving monotherapy and 11 (26%) of 42 patients receiving combination therapy, and included anaemia, anorexia, dehydration, decreased platelet count, diarrhoea, fatigue, fever, increased creatinine, increased alanine aminotransferase, increased aspartate aminotransferase, hyponatraemia, pain, pleural effusion, and pruritus. There were no treatment-related deaths. Nivolumab alone does not warrant further study in an unselected sarcoma population given the limited efficacy. Nivolumab combined with ipilimumab demonstrated promising efficacy in certain sarcoma subtypes, with a manageable safety profile comparable to current available treatment options. The combination therapy met its predefined primary study endpoint; further evaluation of nivolumab plus ipilimumab in a randomised study is warranted.

We assessed the effect of an active case finding (ACF) project on tuberculosis (TB) case notification and the yields from a household and neigbourhood intervention (screening contacts of historical index TB patients diagnosed >24months ago) and a community intervention (screening attendants of health education sessions/mobile clinics). Cross-sectional analysis of project records, township TB registers and annual TB reports. In the household and neigbourhood intervention, of 56,709 people screened, 1,076 were presumptive TB and 74 patients were treated for active TB with a screening yield of 0.1% and a yield from presumptive cases of 6.9%. In the community intervention, of 162,881 people screened, 4,497 were presumptive TB and 984 were treated for active TB with a screening yield of 0.6% and yield from presumptive cases of 21.9%. Of active TB cases, 94% were new, 89% were pulmonary, 44% were bacteriologically-confirmed and 5% had HIV. Case notification rates per 100,000 in project townships increased from 142 during baseline (2011-2013) to 148 during intervention (2014-2016) periods. The yield from household and neigbourhood intervention was lower than community intervention. This finding highlights reconsidering the strategy of screening of contacts from historical index cases. Strategies to reach high-risk groups should be explored for future ACF interventions to increase yield of TB. Copyright © 2018 The Author(s). Published by Elsevier Ltd.. All rights reserved.

A systematic review of occupational safety and health business cases.

2009-12-01

Business cases are commonly developed as means to rationalize investment. We systematically reviewed 26 reported cases on occupational safety and health (OSH) interventions to assess if health and productivity arguments make a good business case. To be included in the review, studies had to analyze the costs and benefits, including productivity, of an OSH intervention at the enterprise level. We searched Medline and Embase for studies and used Google search in addition. Two reviewers independently selected studies and extracted data. The intervention profitability was calculated in euros (euro in 2008) as the first year's benefits minus the total intervention costs per worker. The payback period was calculated as the intervention costs divided by the first year's benefits. We found three ex-ante and 23 ex-post cases. In 20 cases, the study design was a before-after comparison without a control group. Generally a 100% reduction of injuries or sickness absence was assumed. In two cases, productivity and quality increases were very large. The main benefit was avoided sick leave. Depreciation or discounting was applied only in a minority of cases. The intervention profitability was negative in seven studies, up to euro 500 per employee in 12 studies and more than euro 500 per employee in seven studies. The payback period was less than half a year for 19 studies. Only a few studies included sensitivity analyses. Few ex-ante business cases for management decisions on OSH are reported. Guidelines for reporting and evaluation are needed. Business cases need more sound assumptions on the effectiveness of interventions and should incorporate greater uncertainty into their design. Ex-post evaluation should be based preferably on study designs that control for trends at a time different from that of the intervention.

Triptorelin 6-month formulation was developed to offer greater convenience to both patients and physicians by reducing the injection frequency. The efficacy, pharmacokinetics and safety of a new 6-month formulation of triptorelin were investigated over 12 months (48 weeks). The primary objective was to evaluate the formulation in achieving castrate serum testosterone levels (< or = 1.735 nmol/L or < or = 50 ng/dL) on day 29 and in maintaining castration at months 2-12. Absence of luteinizing hormone (LH) stimulation and change in prostate-specific antigen (PSA) level were also assessed. An open-label, non-comparative, phase III study in 120 patients with advanced prostate cancer was conducted from July 2006 to August 2007 in private and public institutions in South Africa. Each patient received two consecutive intramuscular injections of triptorelin embonate (pamoate) 22.5 mg at an interval of 24 weeks. In all patients, testosterone (primary outcome measurement) was measured at baseline and then every 4 weeks; LH was measured before and 2 hours after the two injections. PSA was measured on day 1 and at weeks 12, 24, 36 and 48. Adverse events were recorded at each visit. In the intent-to-treat population, 97.5% (95% CI 92.9, 99.5) of patients achieved castrate serum testosterone levels by day 29, and 93.0% (95% CI 86.8, 97.0) maintained castration at months 2-12. After the second injection, 98.3% of patients showed absence of LH stimulation. The most frequent drug-related adverse events were hot flushes (71.7% of patients). No patient withdrew from the study as a result of an adverse event. The triptorelin 6-month formulation was well tolerated and was able to achieve and maintain castration for the treatment of locally advanced and metastatic prostate cancer. By reducing the frequency of required injections, this new formulation offers a more convenient treatment regimen. (Clinical Trial Registration,NCT00751790 at www.clinicaltrials.gov).

To report the long-term results of osteo-odonto-keratoprosthesis (OOKP) surgery in the visual rehabilitation of patients with corneal blindness from end-stage inflammatory ocular surface disease. A non-comparative retrospective case series of 36 consecutive patients treated at the National OOKP referral centre in Brighton, UK, between November 1996 and March 2006. A total of 36 patients, with age ranging from 19 to 87 years (mean 51 (SD 19) years), were included in the analysis. The main preoperative diagnoses were Stevens-Johnson syndrome (n = 16, or 44%), severe thermal or chemical burns (n = 6, or 17%), and mucous membrane pemphigoid (n = 5, or 14%). The remainder of the cases comprised miscellaneous causes of dry eye (n = 9, or 25%), which included one each of graft versus host disease, ectodermal dysplasia, ionising radiation damage, cicatrising conjunctivitis from topical medication, trachoma, congenital trigeminal nerve hypoplasia, linear IgA disease, Sjögren syndrome and nutritional deficiency. Follow-up ranged from 6 months to 9 years (mean 3.9 (SD 2.5) years). Anatomical retention during the entirety of the follow-up period was seen in 72% of patients. The main factor resulting in anatomical failure was resorption of the OOKP lamina, which occurred in seven cases (or 19%). Predicted resorption in three cases resulted in successful planned exchange of the lamina, but two cases underwent emergency removal of the OOKP, and two cases developed endophthalmitis. Human leucocyte antigen-matched allografts suffered a higher rate of laminar resorption. Out of the entire cohort, 30 patients (or 83%) had some improvement in vision, 28 (or 78%) achieved vision of 6/60 or better, and 19 (or 53%) achieved 6/12 or better. The best-achieved vision was retained throughout the follow-up period in 61% of cases. Survival analysis suggested that the probability of retaining vision >6/60 5 years after surgery was 53 (10)%. Vision-threatening complications occurred in nine cases (or 25%) and included endophthalmitis, retinal detachment and glaucoma. De novo glaucoma occurred in six patients (or 24%) but was seen overall in 17 patients (or 47%), 10 of whom required surgical treatment. OOKP surgery can restore useful and lasting vision in patients suffering from end-stage ocular surface disease, for whom conventional corneal surgery is not possible. The main problems seen in this study were laminar resorption, particularly in allografts, and glaucoma.

Treatment of cutaneous leishmaniasis with thermotherapy in Brazil: an efficacy and safety study*

PubMed Central

2018-01-01

BACKGROUND Pentavalent antimonials remain as the standard drugs in the treatment of cutaneous leishmaniosis. The high cost, difficult administration, long treatment time, toxicity and increasing morbidity are factors that limit the use of these drugs. OBJECTIVES To describe the response to radiofrequency thermotherapy in the treatment of localized cutaneous leishmaniasis in Brazil, and to evaluate its safety and tolerability. METHODS We conducted a non-comparative open trial with a total of 15 patients confirmed to have cutaneous leishmaniasis on parasitological examination. A single radiofrequency thermotherapy session at 50ºC for 30 seconds was applied to the lesion and its edges. In patients with more than one lesion, only the largest one was treated initially. If after 30 days there was no evidence of healing, the smaller lesion was also treated with thermotherapy. Clinical cure was defined as visible healing for three months after treatment. The patients were followed-up for six months and there was no follow-up loss. RESULTS Of all 23 lesions, only two evolved to complete healing without the need of treatment. Of 21 lesions, 18 (85.7%) achieved full healing. The main observed side effects were itching, burning sensation, pain and blisters. STUDY LIMITATIONS Sample with a small number of patients and short follow-up. CONCLUSION Thermotherapy can be considered a therapeutic alternative in localized cutaneous leishmaniasis, especially in cases of single cutaneous lesions and with formal contraindications to conventional treatment with pentavalent antimonials.

Review of Robotic Surgery in Gynecology—The Future Is Here

Lauterbach, Roy; Matanes, Emad; Lowenstein, Lior

2017-01-01

The authors present a systematic review of randomized and observational, retrospective and prospective studies to compare between robotic surgery as opposed to laparoscopic, abdominal, and vaginal surgery for the treatment of both benign and malignant gynecologic indications. The comparison focuses on operative times, surgical outcomes, and surgical complications associated with the various surgical techniques. PubMed was the main search engine utilized in search of study data. The review included studies of various designs that included at least 25 women who had undergone robotic gynecologic surgery. Fifty-five studies (42 comparative and 13 non-comparative) met eligibility criteria. After careful analysis, we found that robotic surgery was consistently connected to shorter post-surgical hospitalization when compared to open surgery, a difference less significant when compared to laparoscopic surgery. Also, it seems that robotic surgery is highly feasible in gynecology. There are quite a few inconsistencies regarding operative times and estimated blood loss between the different approaches, though in the majority of studies estimated blood loss was lower in the robotic surgery group. The high variance in operative times resulted from the difference in surgeon’s experience. The decision whether robotic surgery should become mainstream in gynecological surgery or remain another surgical technique in the gynecological surgeon’s toolbox requires quite a few more randomized controlled clinical trials. In any case, in order to bring robotic surgery down to the front row of surgery, training surgeons is by far the most important goal for the next few years. PMID:28467761

Common procedures and strategies for anaesthesia in interventional radiology.

2015-08-01

This review describes the range of cases now available in the interventional radiology suite and summarizes suggestions for their anaesthetic and perioperative management. The type and complexity of interventional radiology cases being performed increases from year to year. Anaesthesiologists' presence in interventional radiology is increasing in turn, due to increasingly ill patients and intricate procedures requiring more than local anaesthesia for well tolerated completion. The literature available describing this is largely written by radiologists, with little attention paid to anaesthetic considerations. Cases in interventional radiology are complex in terms of the logistics of working in an unfamiliar area, frequency of patient comorbidity and unfamiliar procedures. Ensuring familiarity with the variety of interventional radiology procedures and their periprocedure requirements can increase anaesthesiologists' comfort in interventional radiology.

[Comparison of Flu Outbreak Reporting Standards Based on Transmission Dynamics Model].

PubMed

Yang, Guo-jing; Yi, Qing-jie; Li, Qin; Zeng, Qing

2016-05-01

To compare the current two flu outbreak reporting standards for the purpose of better prevention and control of flu outbreaks. A susceptible-exposed-infectious/asymptomatic-removed (SEIAR) model without interventions was set up first, followed by a model with interventions based on real situation. Simulated interventions were developed based on the two reporting standards, and evaluated by estimated duration of outbreaks, cumulative new cases, cumulative morbidity rates, decline in percentage of morbidity rates, and cumulative secondary cases. The basic reproductive number of the outbreak was estimated as 8. 2. The simulation produced similar results as the real situation. The effect of interventions based on reporting standard one (10 accumulated new cases in a week) was better than that of interventions based on reporting standard two (30 accumulated new cases in a week). The reporting standard one (10 accumulated new cases in a week) is more effective for prevention and control of flu outbreaks.

The Cost-Effectiveness of Integrating HIV Counseling and Testing into Primary Health Care in the Ukraine.

Johns, Benjamin; Doroshenko, Olena; Tarantino, Lisa; Cowley, Peter

2017-03-01

We estimate the number of HIV cases diagnosed, costs, and cost per HIV case detected associated with integrating HIV counseling and testing (HCT) into primary health care facilities in Ukraine. The study uses a difference-in-difference design with four districts implementing the intervention compared to 20 districts where HCT were offered only at specialized HIV clinics. There was a 2.01 (95 % CI: 1.12-3.61) times increase in the number of HIV cases detected per capita in intervention districts compared to other districts. The incremental cost of the intervention was $21,017 and the incremental cost per HIV case detected was $369. The average cost per HIV case detected before the intervention was $558. Engaging primary health care facilities to provide HCT is likely desirable from an efficiency point-of-view. However, the affordability of the intervention needs to be assessed because expansion will require additional investment.

2014-10-01

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

2014-01-01

Globally, TB notifications have stagnated since 2007, and sputum smear positive notifications have been declining despite policies to improve case detection. We evaluate results of 28 interventions focused on improving TB case detection. We measured additional sputum smear positive cases treated, defined as the intervention area's increase in case notification during the project compared to the previous year. Projects were encouraged to select control areas and collect historical notification data. We used time series negative binomial regression for over-dispersed cross-sectional data accounting for fixed and random effects to test the individual projects' effects on TB notification while controlling for trend and control populations. Twenty-eight projects, 19 with control populations, completed at least four quarters of case finding activities, covering a population of 89.2 million. Among all projects sputum smear positive (SS+) TB notifications increased 24.9% and annualized notification rates increased from 69.1 to 86.2/100,000 (p = 0.0209) during interventions. Among the 19 projects with control populations, SS+TB case notifications increased 36.9% increase while in the control populations a 3.6% decrease was observed. Fourteen (74%) of the 19 projects' SS+TB notification rates in intervention areas increased from the baseline to intervention period when controlling for historical trends and notifications in control areas. Interventions were associated with large increases in TB notifications across many settings, using an array of interventions. Many people with TB are not reached using current approaches. Different methods and interventions tailored to local realities are urgently needed.

Meta- and statistical analysis of single-case intervention research data: quantitative gifts and a wish list.

Kratochwill, Thomas R; Levin, Joel R

2014-04-01

In this commentary, we add to the spirit of the articles appearing in the special series devoted to meta- and statistical analysis of single-case intervention-design data. Following a brief discussion of historical factors leading to our initial involvement in statistical analysis of such data, we discuss: (a) the value added by including statistical-analysis recommendations in the What Works Clearinghouse Standards for single-case intervention designs; (b) the importance of visual analysis in single-case intervention research, along with the distinctive role that could be played by single-case effect-size measures; and (c) the elevated internal validity and statistical-conclusion validity afforded by the incorporation of various forms of randomization into basic single-case design structures. For the future, we envision more widespread application of quantitative analyses, as critical adjuncts to visual analysis, in both primary single-case intervention research studies and literature reviews in the behavioral, educational, and health sciences.

Shirayama, Yoshihisa; Phompida, Samlane; Shibuya, Kenji

2009-01-01

Background Insecticide-treated nets (ITNs) are a key intervention to control malaria. The intervention coverage varies as a consequence of geographical accessibility to remote villages and limitations of financial and human resources for the intervention. People's adherence to the intervention, i.e., proper use of ITNs, also affects malaria health outcome. The study objective is to explore the impact of the intervention coverage and people's adherence to the intervention on malaria health outcome among targeted villages in various geographic locations. Methods Geographic information system (GIS) maps were developed using the data collected in an active case detection survey in Khammouane province, Laos. The survey was conducted using rapid diagnostic tests (RDTs) and a structured questionnaire at 23 sites in the province from June to July, the rainy season, in 2005. A total of 1,711 villagers from 403 households participated in the survey. Results As indicated on the GIS maps, villages with malaria cases, lower intervention coverage, and lower adherence were identified. Although no malaria case was detected in most villages with the best access to the district center, several cases were detected in the distal villages, where the intervention coverage and adherence to the intervention remained relatively lower. Conclusion Based on the data and maps, it was demonstrated that malaria remained unevenly distributed within districts. Balancing the intervention coverage in the distal villages with the overall coverage and continued promotion of the proper use of ITNs are necessary for a further reduction of malaria cases in the province.

Walshe, Catherine

2011-12-01

Complex, incrementally changing, context dependent and variable palliative care services are difficult to evaluate. Case study research strategies may have potential to contribute to evaluating such complex interventions, and to develop this field of evaluation research. This paper explores definitions of case study (as a unit of study, a process, and a product) and examines the features of case study research strategies which are thought to confer benefits for the evaluation of complex interventions in palliative care settings. Ten features of case study that are thought to be beneficial in evaluating complex interventions in palliative care are discussed, drawing from exemplars of research in this field. Important features are related to a longitudinal approach, triangulation, purposive instance selection, comprehensive approach, multiple data sources, flexibility, concurrent data collection and analysis, search for proving-disproving evidence, pattern matching techniques and an engaging narrative. The limitations of case study approaches are discussed including the potential for subjectivity and their complex, time consuming and potentially expensive nature. Case study research strategies have great potential in evaluating complex interventions in palliative care settings. Three key features need to be exploited to develop this field: case selection, longitudinal designs, and the use of rival hypotheses. In particular, case study should be used in situations where there is interplay and interdependency between the intervention and its context, such that it is difficult to define or find relevant comparisons.

The objective of this study was to assess the acceptability and feasibility of a cell phone based case manager intervention targeting HIV-infected pregnant women on highly-active antiretroviral therapy (HAART). Pregnant women ≥36 weeks gestation attending antenatal care and receiving HAART through the Option B+ program at a primary care clinic in South Africa were enrolled into a prospective pilot intervention to receive text messages and telephone calls from a case manager through 6 weeks postpartum. Acceptability and feasibility of the intervention were assessed along with infant HIV testing rates and 10-week and 12-month postpartum maternal retention in care. Retention outcomes were compared to women of similar eligibility receiving care prior to the intervention. Fifty women were enrolled into the pilot from May to July 2013. Most (70%) were HAART-naive at time of conception and started HAART during antenatal care. During the intervention, the case manager sent 482 text messages and completed 202 telephone calls, for a median of 10 text messages and 4 calls/woman. Ninety-six percent completed the postpartum interview and 47/48 (98%) endorsed the utility of the intervention. Engagement in 10-week postpartum maternal HIV care was >90% in the pre-intervention (n = 50) and intervention (n = 50) periods; by 12-months retention fell to 72% and was the same across periods. More infants received HIV-testing by 10-weeks in the intervention period as compared to pre-intervention (90.0 vs. 63.3%, p < 0.01). Maternal support through a cell phone based case manager approach was highly acceptable among South African HIV infected women on HAART and feasible, warranting further assessment of effectiveness.

To systematically appraise published comparative effectiveness evidence (clinical and economic) of epidural steroid injections (ESI) for lumbar spinal stenosis and to estimate Medicare reimbursement amounts for ESI procedures. TYPE: Systematic review. PubMed, Embase, and CINAHL were searched through August 2012 for key words that pertain to low back pain, spinal stenosis or sciatica, and epidural steroid injection. We used institutional and Medicare reimbursement amounts for our cost estimation. Articles published in English that assessed ESIs for adults with lumbar spinal stenosis versus a comparison intervention were included. Our search identified 146 unique articles, and 138 were excluded due to noncomparative study design, not having a study population with lumbar spinal stenosis, not having an appropriate outcome, or not being in English. We fully summarized 6 randomized controlled trials and 2 large observational studies. Randomized controlled trial articles were reviewed, and the study population, sample size, treatment groups, ESI dosage, ESI approaches, concomitant interventions, outcomes, and follow-up time were reported. Descriptive resource use estimates for ESIs were calculated with use of data from our institution during 2010 and Medicare-based reimbursement amounts. ESIs or anesthetic injections alone resulted in better short-term improvement in walking distance compared with control injections. However, there were no longer-term differences. No differences between ESIs versus anesthetic in self-reported improvement in pain were reported. Transforaminal approaches had better improvement in pain scores (≤4 months) compared with interlaminar injections. Two observational studies indicated increased rates of lumbar ESI in Medicare beneficiaries. Our sample included 279 patients who received at least 1 ESI during 2010, with an estimated mean total outpatient reimbursement for one ESI procedure "event" to be $637, based on 2010 Medicare reimbursement amounts ($505 technical and $132 professional payments). This systematic review of ESI for treating lumbar spinal stenosis found a limited amount of data that suggest that ESI is effective in some patients for improving select short-term outcomes, but results differed depending on study design, outcome measures used, and comparison groups evaluated. Overall, there are relatively few comparative clinical or economic studies for ESI procedures for lumbar spinal stenosis in adults, which indicated a need for additional evidence. Copyright © 2013.

Objective The aim of this paper was to identify the key factors of case management (CM) interventions among frequent users of healthcare services found in empirical studies of effectiveness. Design Thematic analysis review of CM studies. Methods We built on a previously published review that aimed to report the effectiveness of CM interventions for frequent users of healthcare services, using the Medline, Scopus and CINAHL databases covering the January 2004–December 2015 period, then updated to July 2017, with the keywords ‘CM’ and ‘frequent use’. We extracted factors of successful (n=7) and unsuccessful (n=6) CM interventions and conducted a mixed thematic analysis to synthesise findings. Chaudoir’s implementation of health innovations framework was used to organise results into four broad levels of factors: (1) environmental/organisational level, (2) practitioner level, (3) patient level and (4) programme level. Results Access to, and close partnerships with, healthcare providers and community services resources were key factors of successful CM interventions that should target patients with the greatest needs and promote frequent contacts with the healthcare team. The selection and training of the case manager was also an important factor to foster patient engagement in CM. Coordination of care, self-management support and assistance with care navigation were key CM activities. The main issues reported by unsuccessful CM interventions were problems with case finding or lack of care integration. Conclusions CM interventions for frequent users of healthcare services should ensure adequate case finding processes, rigorous selection and training of the case manager, sufficient intensity of the intervention, as well as good care integration among all partners. Other studies could further evaluate the influence of contextual factors on intervention impacts. PMID:29061623

Integrating between-session interventions (homework) in therapy: the importance of the therapeutic relationship and cognitive case conceptualization.

Between-session interventions, or homework, are crucial to a range of psychological therapies, including cognitive behavior therapy (CBT). Therapeutic interventions often involve experiencing emotions and situations, or examining strongly held views about their problems, that clients can find distressing. Hence, the clinician faces a particular challenge in collaborating with the client to carry out these interventions between sessions. In this article, we convey how this process in CBT requires not only a consideration of the theoretically meaningful determinants of adherence behavior but also a sophisticated cognitive case conceptualization. Using case material, we illustrate the interplay between in-session design, planning, and review of between-session interventions and the conceptualization. We also include a distinction between generic elements of the therapeutic relationship and CBT-specific elements. The case material also attends to the person of the therapist, and his or her own cognitive and emotional reactions occurring throughout the process of discussing between-session interventions. © 2015 Wiley Periodicals, Inc.

There is a growing amount of single-case research literature on the benefits of tablet-mediated interventions for individuals with autism spectrum disorder (ASD). With the development of tablet-based computers, tablet-mediated interventions have been widely utilized for education and treatment purposes; however, the overall quality and evidence of this literature-base are unknown. This article aims to present a quality review of the single-case experimental literature and aggregate results across studies involving the use of tablet-mediated interventions for individuals with ASD. Using the Tau nonoverlap effect size measure, the authors extracted data from single-case experimental studies and calculated effect sizes differentiated by moderator variables. The moderator variables included the ages of participants, participants' diagnoses, interventions, outcome measures, settings, and contexts. Results indicate that tablet-mediated interventions for individuals with ASD have moderate to large effect sizes across the variables evaluated. The majority of research in this review used tablets for video modeling and augmentative and alternative communication. To promote the usability of tablet-mediated interventions for individuals with ASD, this review indicates that more single-case experimental studies should be conducted with this population in naturalistic home, community, and employment settings.

Few outpatients with fractures are treated for osteoporosis in the years following fracture. In a randomized pilot study, we found a nurse case-manager could double rates of osteoporosis testing and treatment compared with a proven efficacious quality improvement strategy directed at patients and physicians (57% vs 28% rates of appropriate care). Few patients with fractures are treated for osteoporosis. An intervention directed at wrist fracture patients (education) and physicians (guidelines, reminders) tripled osteoporosis treatment rates compared to controls (22% vs 7% within 6 months of fracture). More effective strategies are needed. We undertook a pilot study that compared a nurse case-manager to the multifaceted intervention using a randomized trial design. The case-manager counseled patients, arranged bone mineral density (BMD) tests, and prescribed treatments. We included controls from our first trial who remained untreated for osteoporosis 1-year post-fracture. Primary outcome was bisphosphonate treatment and secondary outcomes were BMD testing, appropriate care (BMD test-treatment if bone mass low), and costs. Forty six patients untreated 1-year after wrist fracture were randomized to case-manager (n = 21) or multifaceted intervention (n = 25). Median age was 60 years and 68% were female. Six months post-randomization, 9 (43%) case-managed patients were treated with bisphosphonates compared with 3 (12%) multifaceted intervention patients (relative risk [RR] 3.6, 95% confidence intervals [CI] 1.1-11.5, p = 0.019). Case-managed patients were more likely than multifaceted intervention patients to undergo BMD tests (81% vs 52%, RR 1.6, 95%CI 1.1-2.4, p = 0.042) and receive appropriate care (57% vs 28%, RR 2.0, 95%CI 1.0-4.2, p = 0.048). Case-management cost was $44 (CDN) per patient vs $12 for the multifaceted intervention. A nurse case-manager substantially increased rates of appropriate testing and treatment for osteoporosis in patients at high-risk of future fracture when compared with a multifaceted quality improvement intervention aimed at patients and physicians. Even with case-management, nearly half of patients did not receive appropriate care. clinicaltrials.gov identifier: NCT00152321.

To investigate the in vitro susceptibility of Gram-positive and Gram-negative endophthalmitis bacterial isolates to vancomycin, amikacin, and ceftazidime over a 23-year period. Retrospective non-comparative laboratory case series. Endophthalmitis patients that were culture positive for bacteria. Laboratory records of bacteria isolated from endophthalmitis specimens collected from January 1 st 1993 to December 31 st 2015 were reviewed for incidence and standard susceptibility testing. The in vitro susceptibilities of bacteria cultured from endophthalmitis to vancomycin (VAN), amikacin (AMK), and ceftazidime (CEF). Patients with endophthalmitis were culture positive for bacteria in 665 cases.. Coagulase negative Staphylococci (CoNS) were the most common bacteria (54.6%), followed by Streptococci (Strep) species (20.8%), Staphylococcus aureus (SA) (10.2%), other Gram-positive (other-GP) bacteria (7.4%) and Gram-negative (GN) bacteria (7.1%). All Gram-positive organisms were susceptible to VAN, with the exception of 2 isolates. The in vitro susceptibilities of bacteria to AMK were: CoNS (95.3%), SA (75.0%), Strep (8.0%), GN (95.7%), and other-GP (81.1%). The in vitro susceptibilities of bacteria to CEF were: CoNS (58.5%), SA (54.4%), Strep (84.1%), GN (93.6.%), and other-GP (52.8%). There was no difference between AMK (95.7%) and CEF (93.6%) for GN coverage. AMK provided better coverage than CEF for CoNS, SA, and other-GP bacteria respectively (p<0.05, Fisher's exact), however, CEF appeared to provide better coverage (p<0.001, Fisher's exact) for Strep than AMK. Based on standard in vitro susceptibility testing, vancomycin remains an optimal antibiotic choice for the treatment of Gram-positive endophthalmitis. AMK and CEF appear to provide equal GN coverage, but AMK appears to provide better coverage for CoNS, SA, and other-GP, but not Strep.

According to the hubris hypothesis, observers respond more unfavorably to individuals who express their positive self-views comparatively than to those who express their positive self-views non-comparatively, because observers infer that the former hold a more disparaging view of others and particularly of observers. Two experiments extended the hubris hypothesis in the domain of optimism. Observers attributed less warmth (but not less competence) to, and showed less interest in affiliating with, an individual displaying comparative optimism (the belief that one's future will be better than others' future) than with an individual displaying absolute optimism (the belief that one's future will be good). Observers responded differently to individuals displaying comparative versus absolute optimism, because they inferred that the former held a gloomier view of the observers' future. Consistent with previous research, observers still attributed more positive traits to a comparative or absolute optimist than to a comparative or absolute pessimist. Copyright © 2016.

Bird embryos uncover homology and evolution of the dinosaur ankle.

PubMed

Ossa-Fuentes, Luis; Mpodozis, Jorge; Vargas, Alexander O

2015-11-13

The anklebone (astragalus) of dinosaurs presents a characteristic upward projection, the 'ascending process' (ASC). The ASC is present in modern birds, but develops a separate ossification centre, and projects from the calcaneum in most species. These differences have been argued to make it non-comparable to dinosaurs. We studied ASC development in six different orders of birds using traditional techniques and spin-disc microscopy for whole-mount immunofluorescence. Unexpectedly, we found the ASC derives from the embryonic intermedium, an ancient element of the tetrapod ankle. In some birds it comes in contact with the astragalus, and, in others, with the calcaneum. The fact that the intermedium fails to fuse early with the tibiale and develops an ossification centre is unlike any other amniotes, yet resembles basal, amphibian-grade tetrapods. The ASC originated in early dinosaurs along changes to upright posture and locomotion, revealing an intriguing combination of functional innovation and reversion in its evolution.

Social comparison framing in health news and its effect on perceptions of group risk.

PubMed

Bigman, Cabral A

2014-01-01

News about health disparities often compares health risks faced by different demographic groups. Does this social comparison produce a contrast effect? It was hypothesized that when two racial groups are compared, people would perceive the relatively more at-risk group to be more, and the less at-risk group to be less, at-risk than if the same risk information was presented without the comparative reference group. Three experiments with Black and White respondents tested effects of intergroup social comparison framing (SCF) on perceptions of risk for sexually transmitted infections and skin cancer. SCF (including one White and two Black disparity frames) did not raise respondents' perceived risk regarding the more at-risk racial group, but consistently lowered respondents' risk ratings for the less at-risk racial group. The finding that the same statistic was perceived differently in comparative and noncomparative contexts underscores the importance of considering effects of communication about disparities.

Spanish food composition tables and databases: need for a gold standard for healthcare professionals (review).

PubMed

Lupiañez-Barbero, Ascension; González Blanco, Cintia; de Leiva Hidalgo, Alberto

2018-05-23

Food composition tables and databases (FCTs or FCDBs) provide the necessary information to estimate intake of nutrients and other food components. In Spain, the lack of a reference database has resulted in use of different FCTs/FCDBs in nutritional surveys and research studies, as well as for development of dietetic for diet analysis. As a result, biased, non-comparable results are obtained, and healthcare professionals are rarely aware of these limitations. AECOSAN and the BEDCA association developed a FCDB following European standards, the Spanish Food Composition Database Network (RedBEDCA).The current database has a limited number of foods and food components and barely contains processed foods, which limits its use in epidemiological studies and in the daily practice of healthcare professionals.

Case management is a complex intervention. Complexity arises from the interaction of different components: the model (theoretical basis), implementation context (service), population and health condition, focus for the intervention (client and/or their family), case manager's actions (interventions) and the target of case management (integrated care and support, client's community participation). There is a lack of understanding and a common language. To our knowledge there is no classification (taxonomy) for community-based case management. To develop a community-based case management in brain injury taxonomy (BICM-T), as a common language and understanding of case management for use in quality analysis, policy, planning and practice. The mixed qualitative methods used multiple sources of knowledge including scoping, framing and a nominal group technique to iteratively develop the Beta version (draft) of the taxonomy. A two part developmental evaluation involving case studies and mapping to international frameworks assessed the applicability and acceptability (feasibility) before finalization of the BICM-T. The BICM-T includes a definition of community-based case management, taxonomy trees, tables and a glossary. The interventions domain tree has 9 main actions (parent category): engagement, holistic assessment, planning, education, training and skills development, emotional and motivational support, advising, coordination, monitoring; 17 linked actions (children category); 8 related actions; 63 relevant terms defined in the glossary. The BICM-T provides a knowledge map with the definitions and relationships between the core actions (interventions domain). Use of the taxonomy as a common language will benefit practice, quality analysis, evaluation, policy, planning and resource allocation. Copyright © 2016 The Authors. Published by Elsevier Inc.

2016-01-01

The aim of this study was to explore and describe how client-centred occupational therapy interventions may support and improve the ability to use everyday technology (ET) in work tasks in people with acquired brain injury (ABI). A qualitative, descriptive multiple-case study was designed, and occupation-based interventions were provided to three working-age participants with ABI. Multiple sources were used to collect data throughout the three intervention processes, including assessments, field notes, and interviews. The Canadian Occupational Performance Measure and the Management of Everyday Technology Assessment were administered before the interventions, after the interventions and at a follow-up session 2-3 months subsequent to the interventions. The three intervention processes initially consisted of similar actions, but subsequently the actions took on a different focus and intensity for each case. All of the goals in each of the three case processes were achieved, and both perceived and observed abilities to use ET in work tasks improved. Client-centred occupational therapy interventions might have the potential to improve the ability to use ET in work tasks in people with ABI.

To study the epidemiological and clinical profile of patients with traumatic subluxated lenses at a tertiary care center in India. Ours was a non-comparative descriptive case series. Evaluation of 71 eyes of 71 consecutive patients presenting to the lens clinic over a period of 2 years with traumatic lenticular subluxation was done. Demographic and clinical profile of patients was acquired, followed by a biomicroscopic examination of the cornea, anterior chamber, iris, lens, angles, zonules, anterior vitreous and fundus. Most of the patients were adolescents and belonged to lower socioeconomic status. The mean time lag before presenting was 33.6 months (range 5 days to 40 years) and mean visual acuity in the affected eyes was 1.67 + 0.56 logMAR. Blunt trauma (63/71) was nine times more common than penetrating trauma in the etiology of manifest subluxation. Injury while playing accounted for the highest rate of injury; sports-related injury with a gulli danda or a cricket bat and ball were the most common mode of blunt trauma while bow and arrow injury was the commonest cause of injury in the penetrating trauma subgroup. Cataract was the most frequent ocular association (53.5 %). All eyes had broken zonules and most presented with inferior subluxation (46 %). Traumatic lenticular subluxation, a unilateral cause of zonulolysis usually occurs while playing with a gulli danda, bow and arrow, or cricket bat and ball in Northern India. It is a major cause of severe visual loss and a modification in risk factors is mandatory to decrease ocular morbidity from trauma.

2014-11-01

We aimed to present blepharoplasty techniques we used for severe orbito-temporal neurofibromatosis (NF). A retrospective noncomparative single-center case study was undertaken on patients with orbito-temporal NF. Twenty-two patients with orbito-temporal NF treated at the Department of Ophthalmology of Shanghai Ninth People's Hospital between 2007 and 2011 participated in the study. They underwent a standard ophthalmologic assessment for orbito-temporal NF involving both the orbito-temporal soft tissue and bony orbits. The orbits were examined with three-dimensional computed tomography (CT) and all 22 patients underwent tumor debulking, blepharoplasty, and orbital reconstruction. We modified the conventional procedures. Our reconstructive techniques included eyelid reduction; lateral canthal reattachment; for patients with collapse of the lateral orbital margin, reconstruction of the orbital margin to be performed before reattaching the lateral canthus to the implanted titanium mesh; anterior levator resection; and frontalis suspension according to preoperative levator muscle function. Visual acuity, tumor recurrence, and postoperative palpebral fissure and orbital appearance were evaluated to assess outcomes. Acceptable cosmetic results were obtained in 22 patients after debulking of the orbito-temporal NF and surgical reconstruction. There was no loss of vision or visual impairment postoperatively. All patients did not display recrudescence after a follow-up period of >1 year. Three patients with residual ptosis were successfully treated with a second ptosis repair. We believe that the blepharoplasty techniques described in the treatment of orbito-palpebral NF may provide both functional and esthetic benefits.

Aguado, J-M; Lumbreras, C; González-Vidal, D

2004-09-01

This study assessed the risk of haematological, renal and hepatic toxicity associated with amphotericin B lipid complex (ABLC; Abelcet) in a multicentre, open-label, non-comparative study of 93 patients from 17 different hospitals who received ABLC because of proven or suspected systemic fungal infection or leishmaniasis. Most (66%) patients had onco-haematological diseases. Optimum treatment with ABLC comprised a slow (2-h) infusion dose of 5 mg/kg/day for a minimum period of 14 days. Biochemical and haematological parameters were measured pre-, during and post-treatment. In the overall patient group, the mean serum creatinine concentration was similar pre- and post-study (1.00 +/- 1.14 mg/dL vs. 1.20 +/- 1.19 mg/dL; p > 0.05). There were no significant changes pre- and post-treatment in concentrations of haemoglobin, potassium, transaminases and bilirubin. There was no significant correlation between the dose administered and the concentrations of serum creatinine (Spearmann 0.22). There was no greater nephrotoxicity in the patients with previous renal failure, or in those who had received amphotericin B previously. There were serious adverse events in five patients, but other alternative causes that could explain these events were present in three of these patients. Fevers or chills were experienced by 23% of the patients during the ABLC infusion, but only in one case did this necessitate the suspension of treatment. It was concluded that ABLC is a drug with low nephrotoxicity, even when administered to patients with pre-existing renal insufficiency. Adverse events were generally slight or moderate, and were managed easily with appropriate pre-medication.

This descriptive, non-comparative, phase III study evaluated the safety and tolerability of cell culture-derived (TIVc) and egg-derived (TIV) seasonal influenza vaccines in children at risk of influenza-related complications. Four hundred and thirty subjects were randomized 2:1 to TIVc or TIV. Subjects aged 3 to <9 years received one dose (if previously vaccinated, n=89) or two doses (if not previously vaccinated, n=124) of the study vaccines; the 9 to <18-year-olds (n=213) received one dose. Reactogenicity was assessed for 7 days after vaccination; safety was monitored for 6 months. After any vaccination, the most frequently reported solicited local adverse event (AE) was tenderness/pain (TIVc 44%, 66%, 53% and TIV 56%, 51%, 65% in the age groups 3 to <6 years, 6 to <9 years, and 9 to <18 years, respectively) and the systemic AE was irritability (22% TIVc, 24% TIV) in 3 to <6-year-olds and headache in 6 to <9-year-olds (20% TIVc, 13% TIV) and 9 to <18-year-olds (21% TIVc, 26% TIV). There were no cases of severe fever (≥40°C). No vaccine-related serious AEs were noted. New onset of chronic disease was reported in ≤1% of subjects. TIVc and TIV had acceptable tolerability and similar safety profiles in at-risk children (NCT01998477). Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

2011-01-01

Purpose To report a series of patients with Streptococcus endophthalmitis after injection with intravitreal bevacizumab prepared by the same compounding pharmacy. Design Non-comparative consecutive case series. Methods Medical records and microbiology results of patients who presented with endophthalmitis after injection with intravitreal bevacizumab between July 5 and July 8, 2011, were reviewed. Results Twelve patients were identified with endophthalmitis, presenting 1-6 days after receiving an intravitreal injection of bevacizumab. The injections occurred at four different locations in South Florida. All patients received bevacizumab prepared by the same compounding pharmacy. None of the infections originated at the Bascom Palmer Eye Institute, Miami, FL, although nine patients presented to its tertiary-care ophthalmic emergency room for treatment, and three additional patients were seen in consultation. All patients were treated initially with a vitreous tap and injection; eight patients subsequently received a vitrectomy. Microbiology cultures for ten patients were positive for Streptococcus mitis/oralis. Seven unused syringes of bevacizumab prepared by the compounding pharmacy at the same time as those prepared for the affected patients also were positive for S. mitis/oralis. After four months of follow-up, all but one patient had count-fingers or worse visual acuity, and three required evisceration or enucleation. Local, state and federal health department officials have been investigating the source of the contamination. Conclusions In this outbreak of endophthalmitis after intravitreal bevacizumab injection, Streptococcus mitis/oralis was cultured from the majority of patients and from all unused syringes. Visual outcomes were generally poor. The most likely cause of this outbreak was contamination during syringe preparation by the compounding pharmacy. PMID:22264943

To determine whether a fibrin adhesive can facilitate the performance of sutureless lamellar keratoplasty and attachment of amnion to bare sclera. Prospective, noncomparative case series. Six patients, 5 of whom underwent lamellar keratoplasty and 1 who received an amniotic patch of the sclera and cornea. Institutional review board approval was not required for these therapeutic treatments. In 5 patients, the epithelium was removed from the corneal surface, a free cap, 200- micro m thick, was cut with a microkeratome, and a human fibrin tissue adhesive (Tisseel VH Fibrin Sealant; Baxter Healthcare Corporation, Glendale, CA) was applied to the cut surface of the corneal stroma. A 200- micro m thick, microkeratome-cut lamellar graft was placed in the stromal bed without sutures, and a bandage soft contact lens was applied. The lens was left in place for 1 week and then removed. In 1 patient, the adhesive was applied to bare sclera for attachment of amniotic membrane after removal of a conjunctival melanosis. All patients were followed up for 3 months after surgery. Tissue adhesion, corneal clarity, and visual acuity. All 5 lamellar grafts healed and remained clear, although final visual acuity varied with visual potential and astigmatism. The amniotic membrane graft also adhered well to the bare sclera. The fibrin adhesive provided satisfactory attachment without sutures for lamellar keratoplasty and amniotic patching. It should be effective for sealing of clear cornea incisions, LASIK flaps, and conjunctival and skin grafts. An adhesive that has been designed specifically for ophthalmic applications and is more convenient to use would be desirable.

This study aimed to explore the service needs and preferences of frequent emergency department users with mental health and addictions concerns who participated in a brief intensive case management intervention. We conducted semi-structured individual interviews with 20 frequent emergency department users with mental health and addictions challenges, 13 service providers involved in the delivery of a brief case management intervention, and a focus group with intervention case managers. Thematic analysis was used to explore perceived service user profiles, service needs and preferences of care. Service users experienced complex health and social needs and social isolation, while exhibiting resilience and the desire to contribute. They described multiple instances of stigmatization in interactions with healthcare professionals. Components of the brief intensive case management intervention perceived to be helpful included system navigation, advocacy, intermediation, and practical needs assistance. Frequent service users valued relational responsiveness, a non-judgmental stance, and a recovery orientation in case managers. Interventions for frequent service users in mental health may be enhanced by focusing on the engagement of formal and informal social supports, practical needs assistance, system navigation, advocacy and intermediation, and attention to the recovery goals of service users.

The impact of routine, opt-out HIV testing programs in clinical settings is inconclusive. The objective of this study was to estimate the impact of an expanded, routine HIV testing program in North Carolina sexually transmitted disease (STD) clinics on HIV testing and case detection. Adults aged 18–64 who received an HIV test in a North Carolina STD clinic July 1, 2005 through June 30, 2011 were included in this analysis, dichotomized at the date of implementation on November 1, 2007. HIV testing and case detection counts and rates were analyzed using interrupted time series analysis, and Poisson and multilevel logistic regression. Pre-intervention, 426 new HIV-infected cases were identified from 128,029 tests (0.33%), whereas 816 new HIV-infected cases were found from 274,745 tests post-intervention (0.30%). Pre-intervention, HIV testing increased by 55 tests per month (95% confidence interval [CI]: 41, 72), but only 34 tests per month (95% CI: 26, 42) post-intervention. Increases in HIV testing rates were most pronounced in females and non-Hispanic whites. A slight pre-intervention decline in case detection was mitigated by the intervention (mean difference [MD]=0.01; 95% CI: −0.02, 0.05). Increases in case detection rates were observed among females and non-Hispanic blacks. The impact of a routine HIV screening in North Carolina STD clinics was marginal, with the greatest benefit among persons not traditionally targeted for HIV testing. The use of a pre-intervention comparison period identified important temporal trends that otherwise would have been ignored. PMID:24825338

Single-Case Experimental Designs to Evaluate Novel Technology-Based Health Interventions

PubMed Central

Cassidy, Rachel N; Raiff, Bethany R

2013-01-01

Technology-based interventions to promote health are expanding rapidly. Assessing the preliminary efficacy of these interventions can be achieved by employing single-case experiments (sometimes referred to as n-of-1 studies). Although single-case experiments are often misunderstood, they offer excellent solutions to address the challenges associated with testing new technology-based interventions. This paper provides an introduction to single-case techniques and highlights advances in developing and evaluating single-case experiments, which help ensure that treatment outcomes are reliable, replicable, and generalizable. These advances include quality control standards, heuristics to guide visual analysis of time-series data, effect size calculations, and statistical analyses. They also include experimental designs to isolate the active elements in a treatment package and to assess the mechanisms of behavior change. The paper concludes with a discussion of issues related to the generality of findings derived from single-case research and how generality can be established through replication and through analysis of behavioral mechanisms.

2002-10-01

The efficacy of a new pharmacokinetically enhanced formulation of amoxycillin/clavulanate (AMX/CA) 2000/125 mg, twice daily, designed to provide adequate levels of amoxycillin over the 12-h dosing interval to eradicate penicillin-resistant Streptococcus pneumoniae (PRSP) with amoxycillin (+/-clavulanic acid) MICs of /=4 mg/l. In the pooled comparator group, the success rate at follow-up was 86.5% (45/52). For PRSP (AMX/CA MICs of 0.5-8 mg/l), the overall success rate was 98.2% (55/56) at follow-up for AMX/CA 2000/125 mg and 50.0% (2/4) for comparators. AMX/CA 2000/125 mg shows efficacy comparable to that of the comparators evaluated against S. pneumoniae infections. Due to its favorable pharmacokinetic/pharmacodynamic profile and promising clinical success, the new AMX/CA 2000/125 mg formulation should be considered for the empirical treatment of respiratory tract infections in regions with a high prevalence of antimicrobial-resistant S. pneumoniae and in patients at high risk of antimicrobial-resistant S. pneumoniae infection as this formulation covers many PRSP that are non-susceptible to amoxycillin (+/-clavulanic acid) (MICs of >/=4 mg/l) as well as common beta-lactamase-producing respiratory pathogens.

2014-01-01

Background Masitinib is a highly selective tyrosine kinase inhibitor with activity against the main oncogenic drivers of gastrointestinal stromal tumor (GIST). Masitinib was evaluated in patients with advanced GIST after imatinib failure or intolerance. Patients and methods Prospective, multicenter, randomized, open-label trial. Patients with inoperable, advanced imatinib-resistant GIST were randomized (1 : 1) to receive masitinib (12 mg/kg/day) or sunitinib (50 mg/day 4-weeks-on/2-weeks-off) until progression, intolerance, or refusal. Primary efficacy analysis was noncomparative, testing whether masitinib attained a median progression-free survival (PFS) (blind centrally reviewed RECIST) threshold of >3 months according to the lower bound of the 90% unilateral confidence interval (CI). Secondary analyses on overall survival (OS) and PFS were comparative with results presented according to a two-sided 95% CI. Results Forty-four patients were randomized to receive masitinib (n = 23) or sunitinib (n = 21). Median follow-up was 14 months. Patients receiving masitinib experienced less toxicity than those receiving sunitinib, with significantly lower occurrence of severe adverse events (52% versus 91%, respectively, P = 0.008). Median PFS (central RECIST) for the noncomparative primary analysis in the masitinib treatment arm was 3.71 months (90% CI 3.65). Secondary analyses showed that median OS was significantly longer for patients receiving masitinib followed by post-progression addition of sunitinib when compared against patients treated directly with sunitinib in second-line [hazard ratio (HR) = 0.27, 95% CI 0.09–0.85, P = 0.016]. This improvement was sustainable as evidenced by 26-month follow-up OS data (HR = 0.40, 95% CI 0.16–0.96, P = 0.033); an additional 12.4 months survival advantage being reported for the masitinib treatment arm. Risk of progression while under treatment with masitinib was in the same range as for sunitinib (HR = 1.1, 95% CI 0.6–2.2, P = 0.833). Conclusions Primary efficacy analysis ensured the masitinib treatment arm could satisfy a prespecified PFS threshold. Secondary efficacy analysis showed that masitinib followed by the standard of care generated a statistically significant survival benefit over standard of care. Encouraging median OS and safety data from this well-controlled and appropriately designed randomized trial indicate a positive benefit–risk ratio. Further development of masitinib in imatinib-resistant/intolerant patients with advanced GIST is warranted. PMID:25122671

The aim of this paper was to identify the key factors of case management (CM) interventions among frequent users of healthcare services found in empirical studies of effectiveness. Thematic analysis review of CM studies. We built on a previously published review that aimed to report the effectiveness of CM interventions for frequent users of healthcare services, using the Medline, Scopus and CINAHL databases covering the January 2004-December 2015 period, then updated to July 2017, with the keywords 'CM' and 'frequent use'. We extracted factors of successful (n=7) and unsuccessful (n=6) CM interventions and conducted a mixed thematic analysis to synthesise findings. Chaudoir's implementation of health innovations framework was used to organise results into four broad levels of factors: (1) ,environmental/organisational level, (2) practitioner level, (3) patient level and (4) programme level. Access to, and close partnerships with, healthcare providers and community services resources were key factors of successful CM interventions that should target patients with the greatest needs and promote frequent contacts with the healthcare team. The selection and training of the case manager was also an important factor to foster patient engagement in CM. Coordination of care, self-management support and assistance with care navigation were key CM activities. The main issues reported by unsuccessful CM interventions were problems with case finding or lack of care integration. CM interventions for frequent users of healthcare services should ensure adequate case finding processes, rigorous selection and training of the case manager, sufficient intensity of the intervention, as well as good care integration among all partners. Other studies could further evaluate the influence of contextual factors on intervention impacts. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Vocal cord dysfunction (VCD) or paradoxical vocal-fold motion (PVFM) is a functional disorder of the vocal cords that requires multidisciplinary treatment. Besides relaxation techniques, the use of psychological interventions can help treat the underlying psychological co-morbidities. There is currently no literature that examines the effectiveness of psychological interventions for VCD/PVFM. To review the evidence for psychological interventions used for the treatment of patients with VCD/PVFM. We searched electronic databases for English medical literature using Pubmed (Medline), PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Registry of Controlled Trials, and Clinicaltrials.gov. The date range for our search is from June 1964 to June 2014. We included studies that reported the use of psychological interventions in both adults and children diagnosed with VCD/PVFM. We included randomized controlled trials, case-control studies, retrospective chart reviews, prospective case series, and individual case reports. Most reported studies are small case series or individual case reports that have described the use of interventions such as psychotherapy, behavioral therapy, use of anti-anxiety and anti-depressant medications, and hypnotherapy in conjunction with breathing exercises taught by speech therapists for symptomatic relief. Among the various psychological interventions that have been reported, there is no data regarding effectiveness and/or superiority of one approach over another in either adult or pediatric patients. Psychological interventions have a role to play in the management of adult and pediatric patients with VCD/PVFM. Future prospective studies using uniform approaches for treatment of associated psychopathology may help address this question.

Return-to-work (RTW) after occupational injuries is an important and challenging issue. Case managers are expected to play a vital role in successful RTW. In China, RTW intervention is in its early phase and requires further research and practice. This case report describes Mr. H's RTW process for illustrating the work of a case management team in China. Suggestions on developing and optimizing the process in China are given. After 9 years of absence from work due to severe burn injuries at work, Mr. H was referred for RTW interventions. Mr. H received social and occupational rehabilitation services of 3 months, and the following workplace visits and work trials. After the job placement, the case manager continued the liaison with the worker and employer. Mr. H showed positive changes in occupational and social adjustment after the case management interventions. This was reflected from the shift from the contemplation to action stage on the Lam Assessment of Stages of Employment Readiness. Despite he did not show significant changes on functional capacity and fear avoidance beliefs, Mr. H passed the job credential test and was offered a maintenance technician position at a new company. Both the worker and the employer were satisfied with the outcome of the case management. The RTW interventions carried out by the case managers appeared to be effective within the Chinese system. The results suggested that professional training of case managers, RTW-related policies and technological standards, early integrated interventions should be further developed in China. Disability Adjustment Group Therapy and RTW Support Groups perhaps are useful approaches in workers' returning to work.

Occupational therapists play a key role in addressing the social difficulties of children with ASD. However, interventions are often time intensive, without outcomes generalising beyond the clinic setting. To examine the feasibility and preliminary effectiveness of an intervention to address the social play skills of children with ASD. Participants in this multiple case study design were five children with autism spectrum disorder (ASD), five typically developing playmates and five parents of children with ASD. Two therapists and parents delivered the intervention involving clinic play sessions and home modules. Parents' treatment adherence was recorded. The Test of Playfulness was scored by a blinded rater to examine child outcomes following the intervention. Line graphs were used to examine case data. Percentage of non-overlapping data (PND) was used to calculate the single-case effect size for each child. Parents completed 92.2% of the intervention. Children's case data showed an upwards trend from pre- to post-intervention in four of the five pairs (child with ASD and playmate). However, there was a decrease in scores from post-intervention to the two-month home follow-up for all but one pair. PND indicated the intervention was effective for two children with ASD and three of their playmates, had a questionable effect on three children with ASD and no observable effect on two playmates. The intervention demonstrated preliminary feasibility and effectiveness for improving the social play skills of some children with ASD. Careful consideration is needed to identify which children with ASD and which playmates would be best suited for this intervention approach. © 2016 Occupational Therapy Australia.

Health gains and financial risk protection afforded by public financing of selected interventions in Ethiopia: an extended cost-effectiveness analysis.

The way in which a government chooses to finance a health intervention can affect the uptake of health interventions and consequently the extent of health gains. In addition to health gains, some policies such as public finance can insure against catastrophic health expenditures. We aimed to evaluate the health and financial risk protection benefits of selected interventions that could be publicly financed by the government of Ethiopia. We used extended cost-effectiveness analysis to assess the health gains (deaths averted) and financial risk protection afforded (cases of poverty averted) by a bundle of nine (among many other) interventions that the Government of Ethiopia aims to make universally available. These nine interventions were measles vaccination, rotavirus vaccination, pneumococcal conjugate vaccination, diarrhoea treatment, malaria treatment, pneumonia treatment, caesarean section surgery, hypertension treatment, and tuberculosis treatment. Our analysis shows that, per dollar spent by the Ethiopian Government, the interventions that avert the most deaths are measles vaccination (367 deaths averted per $100,000 spent), pneumococcal conjugate vaccination (170 deaths averted per $100,000 spent), and caesarean section surgery (141 deaths averted per $100,000 spent). The interventions that avert the most cases of poverty are caesarean section surgery (98 cases averted per $100,000 spent), tuberculosis treatment (96 cases averted per $100,000 spent), and hypertension treatment (84 cases averted per $100,000 spent). Our approach incorporates financial risk protection into the economic evaluation of health interventions and therefore provides information about the efficiency of attainment of both major objectives of a health system: improved health and financial risk protection. One intervention might rank higher on one or both metrics than another, which shows how intervention choice-the selection of a pathway to universal health coverage-might involve weighing up of sometimes competing objectives. This understanding can help policy makers to select interventions to target specific policy goals (ie, improved health or financial risk protection). It is especially relevant for the design and sequencing of universal health coverage to meet the needs of poor populations. Copyright © 2015 Verguet et al.

Objectives This study aimed to explore the service needs and preferences of frequent emergency department users with mental health and addictions concerns who participated in a brief intensive case management intervention. Methods We conducted semi-structured individual interviews with 20 frequent emergency department users with mental health and addictions challenges, 13 service providers involved in the delivery of a brief case management intervention, and a focus group with intervention case managers. Thematic analysis was used to explore perceived service user profiles, service needs and preferences of care. Results Service users experienced complex health and social needs and social isolation, while exhibiting resilience and the desire to contribute. They described multiple instances of stigmatization in interactions with healthcare professionals. Components of the brief intensive case management intervention perceived to be helpful included system navigation, advocacy, intermediation, and practical needs assistance. Frequent service users valued relational responsiveness, a non-judgmental stance, and a recovery orientation in case managers. Conclusion Interventions for frequent service users in mental health may be enhanced by focusing on the engagement of formal and informal social supports, practical needs assistance, system navigation, advocacy and intermediation, and attention to the recovery goals of service users.

Miller-Spoto, Marcia; Gombatto, Sara P

2014-06-01

A variety of diagnostic classification systems are used by physical therapists, but little information about how therapists assign diagnostic labels and how the labels are used to direct intervention is available. The purposes of this study were: (1) to examine the diagnostic labels assigned to patient problems by physical therapists who are board-certified Orthopaedic Clinical Specialists (OCSs) and (2) to determine whether the label influences selection of interventions. A cross-sectional survey was conducted. Two written cases were developed for patients with low back and shoulder pain. A survey was used to evaluate the diagnostic label assigned and the interventions considered important for each case. The cases and survey were sent to therapists who are board-certified OCSs. Respondents assigned a diagnostic label and rated the importance of intervention categories for each case. Each diagnostic label was coded based on the construct it represented. Percentage responses for each diagnostic label code and intervention category were calculated. Relative importance of intervention category based on diagnostic label was examined. For the low back pain and shoulder pain cases, respectively, "Combination" (48.5%, 34.9%) and "Pathology/Pathophysiology" (32.7%, 57.3%) diagnostic labels were most common. Strengthening (85.9%, 98.1%), stretching (86.8%, 84.9%), neuromuscular re-education (87.6%, 93.4%), functional training (91.4%, 88.6%), and mobilization/manipulation (85.1%, 86.8%) were considered the most important interventions. Relative importance of interventions did not differ based on diagnostic label (χ2=0.050-1.263, P=.261-.824). The low response rate may limit the generalizability of the findings. Also, examples provided for labels may have influenced responses, and some of the label codes may have represented overlapping constructs. There is little consistency with which OCS therapists assign diagnostic labels, and the label does not seem to influence selection of interventions. © 2014 American Physical Therapy Association.

The Case for Individualized Goal Attainment Scaling Measurement in Elder Abuse Interventions.

PubMed

Burnes, David; Lachs, Mark S

2017-01-01

Research available to inform the development of effective community-based elder abuse protective response interventions is severely limited. Elder abuse intervention research is constrained by a lack of research capacity, including sensitive and responsive outcome measures that can assess change in case status over the course of intervention. Given the heterogeneous nature of elder abuse, standard scales can lack the flexibility necessary to capture the diverse range of individually relevant issues across cases. In this paper, we seek to address this gap by proposing the adaptation and use of an innovative measurement strategy-goal attainment scaling-in the context of elder protection. Goal attainment scaling is an individualized, client-centered outcome measurement approach that has the potential to address existing measurement challenges constraining progress in elder abuse intervention research. © The Author(s) 2015.

Introduction Surgical services are increasingly seen to reduce death and disability in Sub-Saharan Africa, where hospital-based mortality remains alarmingly high. This study explores two implementation approaches to improve the quality of perioperative care in a Tanzanian hospital. Effects were compared to a control group of two other hospitals in the region without intervention. Methods All hospitals conducted quality assessments with a Hospital Performance Assessment Tool. Changes in immediate outcome indicators after one and two years were compared to final outcome indicators such as Anaesthetic Complication Rate and Surgical Case Fatality Rate. Results Immediate outcome indicators for Preoperative Care in the intervention hospital improved (52.5% in 2009; 84.2% in 2011, p<0.001). Postoperative Inpatient Care initially improved to then decline again (63.3% in 2009; 70% in 2010; 58.6% in 2011). In the control group, preoperative care declined from 50.8% (2009) to 32.8% (2011, p <0.001), while postoperative care did not significantly change. Anaesthetic Complication Rate in the intervention hospital declined (1.89% before intervention; 0.96% after intervention, p = 0.006). Surgical Case Fatality Rate in the intervention hospital declined from 5.67% before intervention to 2.93% after intervention (p<0.0010). Surgical Case Fatality Rate in the control group was 4% before intervention and 3.8% after intervention (p = 0.411). Anaesthetic Complication Rate in the control group was not available. Discussion Immediate outcome indicators initially improved, while at the same time final outcome declined (Surgical Case Fatality, Anaesthetic Complication Rate). Compared to the control group, final outcome improved more in the intervention hospital, although the effect was not significant over the whole study period. Documentation of final outcome indicators seemed inconsistent. Immediate outcome indicators seem more helpful to steer the Continuous Quality Improvement program. Conclusion Specific interventions as part of Continuous Quality Improvement might lead to sustainable improvement of the quality of care, if embedded in a multi-faceted approach. PMID:26327392

To evaluate the feasibility and effectiveness of an influenza control bundle to minimize healthcare-associated seasonal influenza transmission among healthcare workers (HCWs) in an intensive care unit (ICU) equipped with central air conditioning. A quasi-experimental study was conducted in a 500-bed tertiary care center in Thailand from July 1, 2005, through June 30,2009. The medical ICU (MICU) implemented an influenza control bundle including healthcare worker (HCW) education, influenza screening of adult community-acquired pneumonia patients, antiviral treatment of patients and ill HCWs who tested positive for influenza, promotion of influenza vaccination among HCWs, and reinforcement of standard infection control policies. The surgical ICU (SICU) and coronary care unit (CCU) received no intervention. The numbers of influenza infections among HCWs during the pre- and postintervention periods were 18 cases in 5,294 HCW days and 0 cases in 5,336 HCW-days in the MICU (3.4 vs 0 cases per 1,000 HCW-days; P ! .001), 19 cases in 4,318 HCW-days and 20 cases in 4,348 HCW-days in the SICU (4.4 vs 4.6 cases per 1,000 HCW-days; Pp.80), and 18 cases in 5,000 HCW-days and 18 cases in 5,143 HCW-days in the CCU (3.6 vs 3.5 cases per 1,000 HCW-days; Pp.92), respectively. Outbreak-related influenza occurred in 7 MICUHCWs, 6 SICU HCWs, and 4 CCU HCWs before intervention and 0 MICU HCWs, 9 SICU HCWs, and 8 CCU HCWs after intervention.Before and after intervention, 25 (71%) and 35 (100%) of 35 MICU HCWs were vaccinated, respectively (P ! .001); HCW vaccination coverage did not change significantly in the SICU (21 [70%] of 30 vs 24 [80%] of 30; Pp.89) and CCU (19 [68%] of 28 vs 21 [75%]of 28; Pp.83). The estimated costs of US $6,471 per unit for postintervention outbreak investigations exceeded the intervention costs of US $4,969. A sustained influenza intervention bundle was associated with clinical and economic benefits to a Thai hospital.

Back pain is a challenge for case management but is a health insurance fund (HIF) that identifies high risk patients and includes them in a back pain assessment and a multimodal program cost-effective? Case managers of a HIF contacted selected patients and requested information on pain and current perspectives. Patients in the intervention group were offered a multimodal assessment and, if applicable, a multimodal treatment program. Control group patients received verbal or written (back book) information. Cost data were evaluated with respect to the interview data 1 year prior and 1 year afterwards. Of the 800 insured persons contacted 621 were nationwide, 88 were regional controls and 91 were intervention patients. Inability to work was still rising in all groups but less in the intervention group versus both control groups. Drugs, hospital as well as cure/adjuvant costs were less for intervention patients than in both control groups. The investment for the program was thus more than refinanced. Case management was well accepted but the intervention was in need of training for case managers and the specific diagnostic and treatment option regionally. The HIF was responsible for the study investment and project partners shared the training of the HIF regional case managers.

Prognosis of phrenic nerve injury following thoracic interventions: four new cases and a review.

2012-04-01

Phrenic nerve lesion is a known complication of thoracic surgical intervention, but it is rarely described following thymectomy and lung surgery. To review the literature on thoracic intervention and phrenic nerve lesion and to describe four new cases, in which regular neurophysiological studies were performed. We reviewed the literature concerning phrenic nerve lesion after cardiac, lung and thymus surgical interventions. We described four cases of phrenic nerve lesion, three associated with thymectomy and one in lung surgery. The review shows that cryogenic or thermal injuries during cardiac surgeries are associated with good prognosis. The information on the outcome of phrenic nerve lesion in thymectomy or lung surgery is insufficient. Our cases and this review suggest that phrenic lesion in the last two interventions are associated with a poor recovery. Our data suggests that the prognosis of phrenic nerve lesion following thoracic intervention depends on the nature of the damage. Probably, in thymectomy and lung surgery, nerve stretch or laceration are involved, consequently the outcome is poorer in comparison with cardiac surgery, where cold lesion is more frequent. Neurophysiological tests give a direct, quantified and reliable assessment of nerve regeneration. Copyright © 2011 Elsevier B.V. All rights reserved.

2016-01-01

Observational studies are increasingly being used for assessing therapeutic interventions. Case-control studies are generally considered to have greater risk of bias than cohort studies, but we lack evidence of differences in effect estimates between the 2 study types. We aimed to compare estimates between cohort and case-control studies in meta-analyses of observational studies of therapeutic interventions by using a meta-epidemiological study. We used a random sample of meta-analyses of therapeutic interventions published in 2013 that included both cohort and case-control studies assessing a binary outcome. For each meta-analysis, the ratio of estimates (RE) was calculated by comparing the estimate in case-control studies to that in cohort studies. Then, we used random-effects meta-analysis to estimate a combined RE across meta-analyses. An RE < 1 indicated that case-control studies yielded larger estimates than cohort studies. The final analysis included 23 meta-analyses: 138 cohort and 133 case-control studies. Treatment effect estimates did not significantly differ between case-control and cohort studies (combined RE 0.97 [95% CI 0.86-1.09]). Heterogeneity was low, with between-meta-analysis variance τ2 = 0.0049. Estimates did not differ between case-control and prospective or retrospective cohort studies (RE = 1.05 [95% CI 0.96-1.15] and RE = 0.99 [95% CI, 0.83-1.19], respectively). Sensitivity analysis of studies reporting adjusted estimates also revealed no significant difference (RE = 1.03 [95% CI 0.91-1.16]). Heterogeneity was also low for these analyses. We found no significant difference in treatment effect estimates between case-control and cohort studies assessing therapeutic interventions.

The effectiveness of different interventions for challenging behavior (CB) in persons with intellectual disabilities (ID) was reviewed by means of a two-phase study. First, a systematic review of 137 meta-analyses and reviews on group-study interventions for CB in persons with ID was conducted. Based on this review, hypotheses concerning the effectiveness of divergent interventions for CB and concerning the impact of variables moderating treatment effectiveness were systematically generated. Second, these hypotheses were tested by means of a multilevel meta-analysis of single-case and small-n research. Two hundred and eighty-five studies reporting on 598 individuals were examined. The average treatment effect was large and statistically significant. However, this effect varied significantly over the included studies and participants. Compared to the meta-analyses and reviews focusing on group-studies in this research domain, the results of the present multilevel meta-analysis of single-case and small-n intervention research provided more detailed knowledge on which specific CB and intervention components moderate the interventions' effectiveness.

Doctor of physical therapy (DPT) student learning about role delineation of physical therapist assistants (PTAs) is essential to ethical and legal practice. Survey assessment of three DPT student cohorts compared collaborative interprofessional case-based learning with PTA students to traditional curriculum delivery strategies. Control cohorts were assessed one time. The intervention group was assessed pre-intervention, immediately post-intervention, and after completing a full-time clinical experience. The case-based learning covered 46% of survey content, allowing for the assessment of content-specific material and potential learning through collaboration. Following the educational intervention, the intervention group improved significantly in areas inside and outside the case-based study content, outscoring both control groups on 25-34% of the survey items. Following the clinical experience, the intervention group declined answer accuracy for patient evaluation and treatment implementation, suggesting unlearning. Improvement in the administrative section was observed after the clinical experience. Perceptions of the tasks within the PTA role were diminished while tasks outside the scope of practice appeared clarified following the clinical experience. While case-based collaborative intraprofessional learning proves effective in student learning about the PTA role, changes following the clinical experience raise questions about the influence of the clinical environment on learning and the practical application of recently learned knowledge.

Both mobile apps and responsive-design websites (web apps) can be used to deliver mobile health (mHealth) interventions, but it can be difficult to discern which to use in research. The goal of this paper is to present four case studies from behavioral interventions that developed either a mobile app or a web app for research and present an information table to help researchers determine which mobile option would work best for them. Four behavioral intervention case studies (two developed a mobile app, and two developed a web app) presented include time, cost, and expertise. Considerations for adopting a mobile app or a web app-such as time, cost, access to programmers, data collection, security needs, and intervention components- are presented. Future studies will likely integrate both mobile app and web app modalities. The considerations presented here can help guide researchers on which platforms to choose prior to starting an mHealth intervention.

To test a virtual case-based Simulated Diabetes Education intervention (SimDE) developed to teach primary care residents how to manage diabetes. Nineteen primary care residency programs, with 341 volunteer residents in all postgraduate years (PGY), were randomly assigned to a SimDE intervention group or control group (CG). The Web-based interactive educational intervention used computerized virtual patients who responded to provider actions through programmed simulation models. Eighteen distinct learning cases (L-cases) were assigned to SimDE residents over six months from 2010 to 2011. Impact was assessed using performance on four virtual assessment cases (A-cases), an objective knowledge test, and pre-post changes in self-assessed diabetes knowledge and confidence. Group comparisons were analyzed using generalized linear mixed models, controlling for clustering of residents within residency programs and differences in baseline knowledge. The percentages of residents appropriately achieving A-case composite clinical goals for glucose, blood pressure, and lipids were as follows: A-case 1: SimDE = 21.2%, CG = 1.8%, P = .002; A-case 2: SimDE = 15.7%, CG = 4.7%, P = .02; A-case 3: SimDE = 48.0%, CG = 10.4%, P < .001; and A-case 4: SimDE = 42.1%, CG = 18.7%, P = .004. The mean knowledge score and pre-post changes in self-assessed knowledge and confidence were significantly better for SimDE group than CG participants. A virtual case-based simulated diabetes education intervention improved diabetes management skills, knowledge, and confidence for primary care residents.

Challenging evidence-based decision-making: a hypothetical case study about return to work.

A hypothetical case study about return to work was used to explore the process of translating research into practice. The method involved constructing a case study derived from the characteristics of a typical, sick-listed employee with non-specific low back pain in Norway. Next, the five-step evidence-based process, including the Patient, Intervention, Co-Interventions and Outcome framework (PICO), was applied to the case study. An inductive analysis produced 10 technical and more fundamental challenges to incorporate research into intervention decisions for an individual with comorbidity. A more dynamic, interactive approach to the evidence-based practice process is proposed. It is recommended that this plus the 10 challenges are validated with real life cases, as the hypothetical case study may not be replicable. Copyright © 2011 John Wiley & Sons, Ltd.

Background The Government of Ethiopia and its partners have deployed artemisinin-based combination therapies (ACT) since 2004 and long-lasting insecticidal nets (LLINs) since 2005. Malaria interventions and trends in malaria cases and deaths were assessed at hospitals in malaria transmission areas during 2001–2011. Methods Regional LLINs distribution records were used to estimate the proportion of the population-at-risk protected by LLINs. Hospital records were reviewed to estimate ACT availability. Time-series analysis was applied to data from 41 hospitals in malaria risk areas to assess trends of malaria cases and deaths during pre-intervention (2001–2005) and post-interventions (2006–2011) periods. Findings The proportion of the population-at-risk potentially protected by LLINs increased to 51% in 2011. The proportion of facilities with ACTs in stock exceeded 87% during 2006–2011. Among all ages, confirmed malaria cases in 2011 declined by 66% (95% confidence interval [CI], 44–79%) and SPR by 37% (CI, 20%–51%) compared to the level predicted by pre-intervention trends. In children under 5 years of age, malaria admissions and deaths fell by 81% (CI, 47%–94%) and 73% (CI, 48%–86%) respectively. Optimal breakpoint of the trendlines occurred between January and June 2006, consistent with the timing of malaria interventions. Over the same period, non-malaria cases and deaths either increased or remained unchanged, the number of malaria diagnostic tests performed reflected the decline in malaria cases, and rainfall remained at levels supportive of malaria transmission. Conclusions Malaria cases and deaths in Ethiopian hospitals decreased substantially during 2006–2011 in conjunction with scale-up of malaria interventions. The decrease could not be accounted for by changes in hospital visits, malaria diagnostic testing or rainfall. However, given the history of variable malaria transmission in Ethiopia, more data would be required to exclude the possibility that the decrease is due to other factors. PMID:25406083

Multi-centre randomised controlled trials (RCTs) in surgery are challenging. It is particularly difficult to establish standards of surgery and ensure that interventions are delivered as intended. This study developed and tested methods for identifying the key components of surgical interventions and standardising interventions within RCTs. Qualitative case studies of surgical interventions were undertaken within the internal pilot phase of a surgical RCT for obesity (the By-Band study). Each case study involved video data capture and non-participant observation of gastric bypass surgery in the operating theatre and interviews with surgeons. Methods were developed to transcribe and synchronise data from video recordings with observational data to identify key intervention components, which were then explored in the interviews with surgeons. Eight qualitative case studies were undertaken. A novel combination of video data capture, observation and interview data identified variations in intervention delivery between surgeons and centres. Although surgeons agreed that the most critical intervention component was the size and shape of the gastric pouch, there was no consensus regarding other aspects of the procedure. They conceded that evidence about the 'best way' to perform bypass was lacking and, combined with the pragmatic nature of the By-Band study, agreed that strict standardisation of bypass might not be required. This study has developed and tested methods for understanding how surgical interventions are designed and delivered delivered in RCTs. Applying these methods more widely may help identify key components of interventions to be delivered by surgeons in trials, enabling monitoring of key components and adherence to the protocol. These methods are now being tested in the context of other surgical RCTs. Current Controlled Trials ISRCTN00786323 , 05/09/2011.

Dengue fever is a severe public heath challenge in south China. A dengue outbreak was reported in Chaozhou city, China in 2015. Intensified interventions were implemented by the government to control the epidemic. However, it is still unknown the degree to which intensified control measures reduced the size of the epidemics, and when should such measures be initiated to reduce the risk of large dengue outbreaks developing? We selected Xiangqiao district as study setting because the majority of the indigenous cases (90.6%) in Chaozhou city were from this district. The numbers of daily indigenous dengue cases in 2015 were collected through the national infectious diseases and vectors surveillance system, and daily Breteau Index (BI) data were reported by local public health department. We used a compartmental dynamic SEIR (Susceptible, Exposed, Infected and Removed) model to assess the effectiveness of control interventions, and evaluate the control effect of intervention timing on dengue epidemic. A total of 1250 indigenous dengue cases was reported from Xiangqiao district. The results of SEIR modeling using BI as an indicator of actual control interventions showed a total of 1255 dengue cases, which is close to the reported number (n = 1250). The size and duration of the outbreak were highly sensitive to the intensity and timing of interventions. The more rigorous and earlier the control interventions implemented, the more effective it yielded. Even if the interventions were initiated several weeks after the onset of the dengue outbreak, the interventions were shown to greatly impact the prevalence and duration of dengue outbreak. This study suggests that early implementation of rigorous dengue interventions can effectively reduce the epidemic size and shorten the epidemic duration.

This study aimed to evaluate the effects of the V1SAGES case management intervention (Vulnerable Patients in Primary Care: Nurse Case Management and Self-management Support) for frequent users of health care services with chronic disease and complex care needs on psychological distress and patient activation. We used a 2-phase sequential mixed methods design. The first phase was a pragmatic randomized controlled trial with intention-to-treat analysis that measured the effects of the intervention compared with usual care on psychological distress and patient activation before and after 6 months. The second phase had a qualitative descriptive design and entailed thematic analysis of in-depth interviews (25 patients, 6 case management nurses, 9 health managers) and focus groups (8 patients' spouses, 21 family physicians) to understand stakeholders' perceived effects of the intervention on patients. A total of 247 patients were randomized into the intervention group (n = 126) or the control group (n = 121). Compared with usual care, the intervention reduced psychological distress (odds ratio = 0.43; 95% CI, 0.19-0.95, P = .04), but did not have any significant effect on patient activation ( P = .43). Qualitative results suggested that patients and their spouses benefitted from the case management intervention, gaining a sense of security, and stakeholders noted better patient self-management of health. Together, our study's quantitative and qualitative results suggest that case management reduces psychological distress, making patients and caregivers feel more secure, whereas impact on self-management is unclear. Case management is a promising avenue to improve outcomes among frequent users of health care with complex needs. © 2018 Annals of Family Medicine, Inc.

Preschool settings vary greatly, and research has shown that interventions are more successful when they can be adapted to individual settings. This is a descriptive case study of how 2 teachers successfully adapted and implemented a preschool physical activity intervention. The Study of Health and Activity in Preschool Environments (SHAPES) was a 3-year physical activity intervention. A detailed case study of 2 high-implementing teachers was conducted. Multiple data sources included accelerometry, direct observation, teacher surveys, and intervention staff field notes. Teacher A focused on integrating physical activity into a wide range of activities, including parent and community events. Teacher B focused on high-intensity, structured activities. Both teachers supported the intervention, worked closely with intervention staff, and operated their classroom as an autonomous unit with support from their directors. Teacher A provided an average of 31.5, 78.0, and 67.5 min of physical activity opportunity per day of observation during years 1, 2, and 3. Teacher B provided an average of 2.7, 33.5, and 73.3 minutes of physical activity opportunity per day of observation. Successful implementation of physical activity interventions may look different in different contexts; thus, interventions should allow for flexible implementation. © 2015, American School Health Association.

Music is an ideal intervention to reduce anxiety and promote relaxation in critically ill patients receiving mechanical ventilatory support. This article reviews the basis for a music listening intervention and describes two case examples with patients utilizing a music listening intervention to illustrate the implementation and use of the music listening protocol in this dynamic environment. The case examples illustrate the importance and necessity of engaging a music therapist in not only assessing the music preferences of patients, but also for implementing a music listening protocol to manage the varied and challenging needs of patients in the critical care setting. Additionally, the case examples presented in this paper demonstrate the wide array of music patients prefer and how the ease of a music listening protocol allows mechanically ventilated patients to engage in managing their own anxiety during this distressful experience.

Randomized controlled trials (RCTs) are widely used in health care research to provide high-quality evidence of effectiveness of an intervention. However, sometimes a study does not require an RCT in order to answer its primary objective; a case-finding design may be more appropriate. The aim of this paper was to introduce a new study design that nests a waiting list RCT within a case-finding study. An example of the new study design is the DOC Study, which primarily aims to determine the diagnostic accuracy of lung function tests for chronic obstructive pulmonary disease. It also investigates the impact of lung function tests on smoking behaviour through use of a waiting list design. The first step of the study design is to obtain participants' consent. Individuals are then randomized to one of two groups; either the 'intervention now' group or the 'intervention later' group, that is, participants are placed on a waiting list. All participants receive the same intervention; the only difference between the groups is the timing of the intervention. The design addresses patient preference issues and recruitment issues that can arise in other trial designs. Potential limitations include differential attrition between study groups and potential demoralization for the 'intervention later' group. The 'waiting list case-finding trial' design is a valuable method that could be applied to case-finding studies; the design enables the case-finding component of a study to be maintained while simultaneously exploring additional hypotheses through conducting a trial. © 2014 John Wiley & Sons, Ltd.

To assess a multicomponent intervention to improve private practitioners (PPs) involvement in referral of presumptive pulmonary TB (PTB) cases to the Revised National TB Control Programme (RNTCP) for sputum examination. Randomised controlled trial. We randomly allocated all 189 eligible PPs in Tumkur city, South India, to intervention or control arm. The intervention, implemented between December 2014 and January 2016, included two sets of activities, one targeted at health system strengthening (building RNTCP staff capacity to collaborate with PPs, provision of feedback on referrals through SMS) and one targeted at intervention PPs (training in RNTCP, provision of referral pads and education materials and monthly visits to PPs by RNTCP staff). Crude and adjusted referral and PTB case-finding rate ratios were calculated with negative binomial regression. PPs referred 836 individuals (548 from intervention and 169 from control arm PPs) of whom 176 were diagnosed with bacteriologically confirmed PTB. The proportion (95% confidence interval) of referring PPs [0.59 (0.49, 0.68) vs. 0.42 (0.32, 0.52) in the intervention and control arm, respectively], mean referral rate per PP-year [(5.7 (3.8, 8.7) vs. 1.8 (1.2, 2.8)] and smear-positive PTB case-finding rate per PP-year [(1.5 (0.9, 2.2) vs. 0.6 (0.3, 0.9)] were significantly higher in the intervention than the control arm. Stratifying by qualification, a statistically significant difference in the above indicators remained only among GPs and internists. Overall, surgeons, paediatricians and gynaecologists referred few patients. PP referrals contributed to 20% of the sputum smear positive PTB cases detected by RNTCP in Tumkur city (14% were from intervention arm PPs). We demonstrated the effectiveness of a health system-oriented intervention to improve PP's referrals of presumptive PTB cases to RNTCP. © 2018 John Wiley & Sons Ltd.

Case management is a type of intervention expected to improve the quality of care and therefore the quality of life of frail, community-dwelling older people while delaying institutionalisation in nursing homes. However, the heterogeneity, multidimensionality and complexity of these interventions make their evaluation by the means of classical approaches inadequate. Our objective was twofold: (i) to propose a tool allowing for the identification of the key components that explain the success of case management for this population and (ii) to propose a typology based on the results of this tool. The process started with a multiple embedded case study design in order to identify the key components of case management. Based on the results of this first step, data were collected among 22 case management interventions, in order to evaluate their expected effectiveness. Finally, multiple correspondence analyses was conducted to propose a typology of case management. The overall approach was informed by Wagner's Chronic Care Model and the theory of complexity. The study identified a total of 23 interacting key components. Based on the clustering of response patterns of the 22 case management projects included in our study, three types of case management programmes were evidenced, situated on a continuum from a more "socially-oriented" type towards a more "clinically-oriented" type of case management. The type of feedback provided to the general practitioner about both the global geriatric assessment and the result of the intervention turned out to be the most discriminant component between the types. The study design allowed to produce a tool that can be used to distinguish between different types of case management interventions and further evaluate their effect on frail older people in terms of the delaying institutionalisation, functional and cognitive status, quality of life and societal costs.

Hysteroscopic Tubal Sterilization

PubMed Central

McMartin, K

2013-01-01

Background Hysteroscopic tubal sterilization is a minimally invasive alternative to laparoscopic tubal ligation for women who want permanent contraception. The procedures involves non-surgical placement of permanent microinserts into both fallopian tubes. Patients must use alternative contraception for at least 3 months postprocedure until tubal occlusion is confirmed. Compared to tubal ligation, potential advantages of the hysteroscopic procedure are that it can be performed in 10 minutes in an office setting without the use of general or even local anesthesia. Objective The objective of this analysis was to determine the effectiveness and safety of hysteroscopic tubal sterilization compared with tubal ligation for permanent female sterilization. Data Sources A standard systematic literature search was conducted for studies published from January 1, 2008, until December 11, 2012. Review Methods Observational studies, randomized controlled trials (RCTs), systematic reviews and meta-analyses with 1 month or more of follow-up were examined. Outcomes included failure/pregnancy rates, adverse events, and patient satisfaction. Results No RCTs were identified. Two systematic reviews covered 22 observational studies of hysteroscopic sterilization. Only 1 (N = 93) of these 22 studies compared hysteroscopic sterilization to laparoscopic tubal ligation. Two other noncomparative case series not included in the systematic reviews were also identified. In the absence of comparative studies, data on tubal ligation were derived for this analysis from the CREST study, a large, multicentre, prospective, noncomparative observational study in the United States (GRADE low). Overall, hysteroscopic sterilization is associated with lower pregnancy rates and lower complication rates compared to tubal ligation. No deaths have been reported for hysteroscopic sterilization. Limitations A lack of long-term follow-up for hysteroscopic sterilization and a paucity of studies that directly compare the two procedures limit this assessment. In addition, optimal placement of the microinsert at the time of hysteroscopy varied among studies. Conclusions Hysteroscopic sterilization is associated with: lower pregnancy rates compared to tubal ligation (GRADE very low) lower complication rates compared to tubal ligation (GRADE very low) no significant improvement in patient satisfaction compared to tubal ligation (GRADE very low) Plain Language Summary Hysteroscopic tubal sterilization is a minimally invasive alternative to conventional tubal ligation for women who want a permanent method of contraception. Both approaches involve closing off the fallopian tubes, preventing the egg from moving down the tube and the sperm from reaching the egg. Tubal ligation is a surgical procedure to tie or seal the fallopian tubes, and it usually requires general anesthesia. In contrast, hysteroscopic tubal sterilization can be performed in 10 minutes in an office setting without general or even local anesthesia. A tiny device called a microinsert is inserted into each fallopian tube through the vagina, cervix, and uterus without surgery. An instrument called a hysteroscope allows the doctor to see inside the body for the procedure. Once the microinserts are in place, scar tissue forms around them and blocks the fallopian tubes. Health Quality Ontario conducted a review of the effectiveness and safety of hysteroscopic tubal sterilization compared to tubal ligation. This review indicates that hysteroscopic tubal sterilization is associated with: lower pregnancy rates compared to tubal ligation lower complication rates compared to tubal ligation no significant improvement in patient satisfaction compared to tubal ligation However, we found a number of limitations to the studies available on hysteroscopic tubal sterilization. Among other concerns, most studies did not include long-term follow-up and only 1 study directly compared hysteroscopic tubal sterilization to tubal ligation. PMID:24228084

Theory-based and evidence-based design of audit and feedback programmes: examples from two clinical intervention studies.

2017-04-01

Audit and feedback (A&F) is a common intervention used to change healthcare provider behaviour and, thus, improve healthcare quality. Although A&F can be effective its effectiveness varies, often due to the details of how A&F interventions are implemented. Some have suggested that a suitable conceptual framework is needed to organise the elements of A&F and also explain any observed differences in effectiveness. Through two examples from applied research studies, this article demonstrates how a suitable explanatory theory (in this case Kluger & DeNisi's Feedback Intervention Theory (FIT)) can be systematically applied to design better feedback interventions in healthcare settings. Case 1: this study's objective was to reduce inappropriate diagnosis of catheter-associated urinary tract infections (CAUTI) in inpatient wards. Learning to identify the correct clinical course of action from the case details was central to this study; consequently, the feedback intervention featured feedback elements that FIT predicts would best activate learning processes (framing feedback in terms of group performance and providing of correct solution information). We designed a highly personalised, interactive, one-on-one intervention with healthcare providers to improve their capacity to distinguish between CAUTI and asymptomatic bacteruria (ASB) and treat ASB appropriately. Case 2: Simplicity and scalability drove this study's intervention design, employing elements that FIT predicted positively impacted effectiveness yet still facilitated deployment and scalability (eg, delivered via computer, delivered in writing). We designed a web-based, report-style feedback intervention to help primary care physicians improve their care of patients with hypertension. Both studies exhibited significant improvements in their desired outcome and in both cases interventions were received positively by feedback recipients. A&F has been a popular, yet inconsistently implemented and variably effective tool for changing healthcare provider behaviour and, improving healthcare quality. Through the systematic use of theory such as FIT, robust feedback interventions can be designed that yield greater effectiveness. Future work should look to comparative effectiveness of specific design elements and contextual factors that identify A&F as the optimal intervention to effectuate healthcare provider behaviour change.

Lower gastrointestinal bleeding (LGIB) along with intestinal perforation is a well-known complication of typhoid fever. Reports of colonoscopic appearance and intervention of typhoid perforation involve only few cases. This series reports the colonoscopic findings and the role of colonoscopic hemostatic interventions in controlling the bleeding ileocolonic lesions. During the typhoid fever outbreak in Sulaymaniyah City in Iraqi Kurdistan Region, we received 52 patients with LGIB manifesting as fresh bleeding per rectum or melena. We performed total colonoscopy with ileal intubation for all cases. The findings were recorded and endoscopic hemostatic intervention with adrenaline-saline injection and argon plasma coagulation was applied to actively bleeding lesion. These patients were young, 11-30 years of age, with female preponderance. Blood culture was positive in 50 %. Colonoscopic findings were mostly located in the ileocecal region, although other areas of the colon were involved in many cases. Twenty-four percent of the cases required endoscopic hemostatic intervention by adrenaline injection with argon plasma coagulation which was effective in all patients except one who died in spite of surgical intervention in addition of endoscopic hemostasis. Dual endoscopic hemostatic intervention can be a safe and effective management option for patients with LGIB due to typhoid fever.

This study is to estimate the effectiveness of a diabetic case management programme on health-care service utilization. The study population included 6007 as the intervention group and 956,766 as the control group. As the indicators of health-care service utilization, numbers of medical ambulatory consultations, days of medication prescribed and medical expenses for one year were used, and we analysed the claim data of the health insurance from 2005 to 2007. The study population was classified into three subgroups based on the number of medical ambulatory consultations per year before this intervention. In the under-serviced subgroup, the intervention group showed a significant increase in the number of consultations (3.2), days of prescribed medication (66.4) and medical expenses (287,900 KRW) compared with the control group. Conversely, in the over-serviced subgroup, the intervention group showed a less decrease days of prescribed medication (1.6) compared with the control group. This showed that the case management programme led the intervention group to optimize their utilization of health-care services by subgroups. It is necessary to evaluate the appropriateness of health-care usage and clinical outcome to show the direct effectiveness of the case management programme by subgroups. © 2014 Wiley Publishing Asia Pty Ltd.

Approximately 100,000 cases of upper gastrointestinal bleeding (UGIB) require inpatient admission annually in the United States. When medical management and endoscopic therapy are inadequate, endovascular intervention can be lifesaving. These emergent situations highlight the importance of immediate competence of the interventional radiologist in the preangiographic evaluation as well as the endovascular treatment of UGIB.

This paper explores the application of alternative approaches to economic evaluation of public health interventions, using a worked example of exercise referral schemes (ERSs). Cost-utility (CUA) and cost-consequence analyses (CCA) were used to assess the cost-effectiveness of ERSs. For the CUA, evidence was synthesized using a decision analytic model that adopts a lifetime horizon and NHS/Personal Social Services perspective. Outcomes were expressed as incremental cost per quality-adjusted life-year (QALY). CCA was conducted from a partial-societal perspective, including health and non-healthcare costs and benefits. Outcomes were reported in natural units, such as cases of strokes or CHD avoided. Compared with usual care, the incremental cost per QALY of ERS is £20 876. Based on a cohort of 100 000 individuals, CCA estimates cost of ERS at £22 million to the healthcare provider and £12 million to participants. The benefits of ERS include additional 3900 people becoming physically active, 51 cases of CHD avoided, 16 cases of stroke avoided, 86 cases of diabetes avoided and a gain of ∼800 QALYs. CCA might provide greater transparency than CUA in reporting the outcomes of public health interventions and have greater resonance with stakeholders involved in commissioning these interventions.

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.

To evaluate the visual outcomes after laser in situ keratomileusis (LASIK) surgery to correct primary compound myopic astigmatism with high cylinder performed using a fast-repetition-rate excimer laser platform with optimized aspheric profiles and cyclotorsion control. Vissum Corporation and Division of Ophthalmology, Universidad Miguel Hernández, Alicante, Spain. Retrospective consecutive observational nonrandomized noncomparative case series. Eyes with primary compound myopic astigmatism and a cylinder power over 3.00 diopters (D) had uneventful LASIK with femtosecond flap creation and fast-repetition-rate excimer laser ablation with aspheric profiles and cyclotorsion control. Visual, refractive, and aberrometric outcomes were evaluated at the 6-month follow-up. The astigmatic correction was evaluated using the Alpins method and Assort software. The study enrolled 37 eyes (29 patients; age range 19 to 55 years). The significant reduction in refractive sphere and cylinder 3 months and 6 months postoperatively (P<.01) was associated with improved uncorrected distance visual acuity (P<.01). Eighty-seven percent of eyes had a spherical equivalent within ±0.50 D; 7.5% of eyes were retreated. There was no significant induction of higher-order aberrations (HOAs). The targeted and surgically induced astigmatism magnitudes were 3.23 D and 2.96 D, respectively, and the correction index was 0.91. The safety and efficacy indices were 1.05 and 0.95, respectively. Laser in situ keratomileusis for primary compound myopic astigmatism with high cylinder (>3.00 D) performed using a fast-repetition-rate excimer laser with optimized aspheric profiles and cyclotorsion control was safe, effective, and predictable and did not cause significant induction of HOAs.

2017-01-05

BACKGROUND The aim of the present study was to establish the normal-range orbital parameters and to explore the relationships between ocular protrusion and various orbital morphological factors. MATERIAL AND METHODS A retrospective, non-comparative case series was conducted from January 2014 to December 2015. We recruited 56 subjects (112 orbits), including 27 males (21 to 87 years of age) and 29 females (22 to 88 years of age) in this study. Nine length measurements, 2 angle measurements, and 2 volume measurements of various aspects of the orbit were obtained using Mimics v18.0 software. The data were collected manually using a 3D measurement technique. Statistical analyses using t tests and Pearson's correlation analyses were performed to evaluate the differences and relationships between the parameters, respectively. RESULTS Ocular protrusion in both sexes was closely related to the following values: orbital soft tissue volume (OSTV) (males: r=0.61, p<0.001; females: r=0.39, p=0.003), orbital soft tissue volume/bony orbital volume (OSTV/BOV) (males: r=0.90, p<0.001; females: r=0.87, p<0.001), orbital width (males: r=0.40, p=0.003; females: r=0.53, p<0.001), orbital height (males: r=0.29, p=0.038; females: r=0.45, p<0.001), and globe diameter (males: r=0.52, p<0.001; females: r=0.48, p<0.001). No differences were found between the right and left orbits. CONCLUSIONS The study provides insight into the potential factors that influence ocular protrusion, which include the OSTV/BOV ratio, the shape of the orbital aperture, and the ocular axial length. The results of orbital surgery can be made more predictable by accounting for these 3 factors. The database and regression formula might provide support for surgical planning in the future.

Abstract Background Evidences for antipsychotic augmentation for schizophrenic patients with sub-optimal efficacy have been lacking although it has been widespread therapeutic strategy in clinical practice. The purpose of this study was to investigate the efficacy and tolerability of blonanserin augmentation with an atypical antipsychotics (AAPs) in schizophrenic patients. Methods A total of 100 patients with schizophrenia partially or completely unresponsive to treatment with an AAP recruited in this 12-week, open-label, non-comparative, multicenter study. Blonanserin was added to existing AAPs which were maintained during the study period. Efficacy was primarily evaluated using Positive and Negative Syndrome Scale (PANSS) at baseline, week 2, 4, 8, and 12. Predictors for PANSS response (≥20% reduction) was investigated. Results The PANSS total score was significantly decreased at 12 weeks after blonanserin augmentation (-21.0 ± 18.1, F=105.849, p<0.001). Response rate on PANSS at week 12 was 51.0%. Premature discontinuation was occurred in 17 patients (17.0%) and 4 patients among them discontinued the study due to adverse events. Nine patients experienced significant weight gain during the study. Response to blonanserin augmentation was associated with severe (PANSS>85) baseline symptom (OR=10.298, p=0.007) and higher dose (>600mg/day of chlorpromazine equivalent dose) of existing AAPs (OR=4.594, p=0.014). Discussion Blonanserin augmentation improved psychiatric symptoms of schizophrenic patients in cases of partial or non-responsive to an AAP treatment with favorable tolerability. Patients with severe symptom despite treatment with higher dose of AAP were benefited from this augmentation. These results suggested that blonanserin augmentation could be an effective strategy for specific patients with schizophrenia.

To evaluate the surgical outcomes of cataract surgery in eyes with a low preoperative corneal endothelial cell density (ECD) and analyze factors affecting the prognosis. Tokyo Dental College, Ichikawa General Hospital, Chiba, Japan. Noncomparative case series. Eyes with a preoperative ECD of less than 1000 cells/mm(2) that had cataract surgery between 2006 and 2010 were identified. Standard phacoemulsification with intraocular lenses was performed using the soft-shell technique. The rate of endothelial cell loss, incidence of bullous keratopathy, and risk factors were retrospectively assessed. Sixty-one eyes (53 patients) with a low preoperative ECD were identified. Preoperative diagnoses or factors regarded as causing endothelial cell loss included Fuchs dystrophy (20 eyes), laser iridotomy (16 eyes), keratoplasty (10 eyes), traumatic injury (3 eyes), trabeculectomy (3 eyes), corneal endotheliitis (2 eyes), and other (7 eyes). The corrected distance visual acuity improved from 0.59 ± 0.49 logMAR preoperatively to 0.32 ± 0.48 logMAR postoperatively (P<.001). The mean ECD was 693 ± 172 cells/mm(2) and 611 ± 203 cells/mm(2), respectively (P=.001). The mean rate of endothelial cell loss was 11.5% ± 23.4%. Greater ECD loss was associated with a shorter axial length (AL) (<23.0 mm) and diabetes mellitus. Bullous keratopathy developed in 9 eyes (14.8%) and was associated with posterior capsule rupture. The results suggest that modern techniques for cataract surgery provide excellent visual rehabilitation in many patients with a low preoperative ECD. Shorter AL, diabetes mellitus, and posterior capsule rupture were risk factors for greater ECD loss and bullous keratopathy. Copyright © 2011 ASCRS and ESCRS. Published by Elsevier Inc.

The purpose of this study is to provide a review of the ocular injuries sustained by survivors of the April 19, 1995, bombing of the Alfred P. Murrah Federal Building in Oklahoma City. Retrospective, noncomparative case series. The authors retrospectively evaluated data collected on all surviving persons receiving ocular injuries during the bombing and on all at-risk occupants of the federal building and four adjacent buildings. Injury data from survivors were collected from multiple sources to include hospital medical records, a physician survey, emergency medical services run reports, written survivor accounts, building occupant survey, telephone interviews, and mail surveys. The types of ocular injuries, the associated systemic injuries, and the location of the injured at the time of the blast were evaluated. Fifty-five (8%) of the 684 injured bombing survivors sustained an ocular injury. Persons injured in the Murrah building were more than three times more likely to sustain an ocular injury than other injured persons. Seventy-one percent of ocular injuries occurred within 300 feet of the point of detonation. The most common serious ocular injuries included lid/brow lacerations (20 patients, 23 eyes), open globe injuries (12 eyes), orbital fractures (6 eyes), and retinal detachment (5 eyes). A retained intraocular foreign body accounted for only two of the injuries (4%). Glass accounted for nearly two thirds of the ocular injuries. Blasts involving explosions inflict severe ocular injury, mostly as a result of secondary blast effects from glass, debris, etc. Eye injuries in bombings can probably be prevented by increasing the distance from and orientation away from windows (i.e., by facing desks away from windows). Use of such products as laminated glass, toughened window glazing, and Mylar curtains may reduce glass projectiles in the blast vicinity.

Medical Malpractice Claims Related to Cataract Surgery Complicated by Retained Lens Fragments (An American Ophthalmological Society Thesis)

2012-01-01

Purpose: To review malpractice claims associated with retained lens fragments during cataract surgery to identify ways to improve patient outcomes. Methods: Retrospective, noncomparative, consecutive case series. Closed claims data related to cataract surgeries complicated by retained lens fragments (1989 through 2009) from an ophthalmic insurance carrier were reviewed. Factors associated with these claims and claims outcomes were analyzed. Results: During the 21-year period, 117 (12.5%) of 937 closed claims associated with cataract surgery were related to retained lens fragments with 108 unique cataract surgeries, 97% against cataract surgeon and 3% against retinal surgeon. Twelve (11%) of 108 claims were resolved by a trial, 30 (28%) were settled, and 66 (61%) were dismissed. The defendant prevailed in 83% of trials. Indemnity payments totaling more than $3,586,000 were made in 32 (30%) of the claims (median payment, $90,000). The difference between the preoperative visual acuity and the final visual acuity was predictive of an indemnity payment (odds ratio [OR], 2.28; P=.001) and going to a trial (OR, 2.93; P=.000). Development of corneal edema was associated with an indemnity payment (OR, 3.50; P=.037). Timing of referral and elevated intraocular pressure (IOP) were statistically significant in univariate analyses but not in multivariate analyses for a trial. Conclusions: Whereas the majority of claims were dismissed, claims associated with greater visual acuity decline, corneal edema, or elevated IOP were more likely to result in a trial or payment. Ways to reduce significant vision loss, including improved management of corneal edema and IOP, and timely referral to a subspecialist should be considered. PMID:23818737

Abstract Purpose Elastic stable intramedullary nailing is increasingly used for surgical treatment of tibial shaft fractures, but frequently requires immobilization and delayed full weight-bearing. Therefore, external fixation remains interesting. The aim was to report clinico-radiological outcomes of monolateral external fixation for displaced and unstable tibial shaft fractures in children. Methods All tibial fractures consecutively treated by monolateral external fixation between 2008 and 2013 were followed. Inclusion criteria included skeletal immaturity and closed and open Gustilo I fractures caused by a direct impact. Patients were seen until two years postoperatively. Demographics, mechanism of injury, surgical data and complications were recorded. Anteroposterior and lateral side radiographs were performed at each visit. Full-limb 3D reconstructions using biplanar stereroradiography was performed for final limb length and alignment measures. Results A total of 45 patients (mean age 9.7 years ± 0.5) were included. In all, 17 were Gustilo I fractures, with no difference between open and closed fractures for any data. Mean time to full weight bearing was 18.2 days ± 0.7. After 15 days, 39 patients returned to school. Hardware removal (mean time to union 15.6 weeks ± 0.8) was performed during consultation under analgesic gas. There were no cases of nonunion. No fracture healed with > 10° of angulation (mean 5.1° ± 0.4°). Leg-length discrepancy > 10 mm was found for six patients. Conclusions This procedure can be a safe and simple surgical treatment for children with tibial shaft fractures. Few complications and early return to school were reported, with the limitations of non-comparative study. Level of Evidence IV PMID:29456750

Lean management in health care: definition, concepts, methodology and effects reported (systematic review protocol)

PubMed Central

2014-01-01

Background Lean is a set of operating philosophies and methods that help create a maximum value for patients by reducing waste and waits. It emphasizes the consideration of the customer’s needs, employee involvement and continuous improvement. Research on the application and implementation of lean principles in health care has been limited. Methods This is a protocol for a systematic review, following the Cochrane Effective Practice and Organisation of Care (EPOC) methodology. The review aims to document, catalogue and synthesize the existing literature on the effects of lean implementation in health care settings especially the potential effects on professional practice and health care outcomes. We have developed a Medline keyword search strategy, and this focused strategy will be translated into other databases. All search strategies will be provided in the review. The method proposed by the Cochrane EPOC group regarding randomized study designs, non-randomised controlled trials controlled before and after studies and interrupted time series will be followed. In addition, we will also include cohort, case–control studies, and relevant non-comparative publications such as case reports. We will categorize and analyse the review findings according to the study design employed, the study quality (low- versus high-quality studies) and the reported types of implementation in the primary studies. We will present the results of studies in a tabular form. Discussion Overall, the systematic review aims to identify, assess and synthesize the evidence to underpin the implementation of lean activities in health care settings as defined in this protocol. As a result, the review will provide an evidence base for the effectiveness of lean and implementation methodologies reported in health care.

To explore the efficacy and safety of imiquimod 5% cream as a treatment for infantile hemangioma. Phase II, open-label, noncomparative study of imiquimod applied during 16 weeks, with posttherapy follow-up 16 weeks later (8 months total). Outpatient pediatric tertiary care referral center in Quebec, Canada. Healthy infants up to 8.8 months of age with previously untreated, nonulcerated, proliferative superficial or mixed infantile hemangioma, excluding periorbital, or perineal localization, > or =100 cm2 in size. Topical imiquimod applied three to seven times per week for 16 weeks to infantile hemangioma. Lesion area, volume, depth (Doppler ultrasound), and color (erythema), serum drug, and interferon-alpha levels. Sixteen infants (11 girls, 5 boys) with a mean age at entry of 4.1 months and mean lesion area of 32.89 cm2, and volume of 39.98 cm3 were enrolled. Two participants discontinued treatment early, one for an adverse event (crying upon application), the other because of the lack of compliance. Local skin reactions were consistent with those reported in adults. Two cases had a decrease and three had an increase in lesion parameters; otherwise no meaningful changes in lesion area, volume, or depth were observed. At the 4-month posttreatment visit, 11 of 14 subjects had improvement in erythema (marginal homogeneity test = 2.668, p = 0.008). Measured serum drug and interferon-alpha levels were low or undetectable. Treatment of infants with infantile hemangioma with imiquimod up to seven times per week for 16 weeks was generally well tolerated with low systemic exposure. Improvement was observed in hemangioma coloration, but not lesion size, suggesting effects were limited to the superficial component.

Posterior segment manifestations of active ocular syphilis, their response to a neurosyphilis regimen of penicillin therapy, and the influence of human immunodeficiency virus status on response.

To determine the relative frequencies of signs in posterior segment ocular syphilis, the response to a neurosyphilis regimen of penicillin, and differences in findings between human immunodeficiency virus (HIV)-coinfected and -noncoinfected patients in a community setting. Retrospective, noncomparative, consecutive case series. Fourteen consecutive patients with posterior segment ocular syphilis over a 14-year period within or during the acquired immune deficiency syndrome era. Neurosyphilis intravenous penicillin regimen. Initial and final visual acuity; treponemal and nontreponemal serologic analyses; cerebrospinal fluid cell count, protein, and Venereal Disease Research Laboratory analyses; posterior segment signs; and relapses and recurrences. Blacks and males were predominantly affected. Five (36%) of patients were HIV coinfected, and ocular syphilis led to the HIV infection diagnosis in three. Four (29%) patients had received previous antibiotic therapy for primary or secondary syphilis, raising the suspicion of relapse. Two patients had negative nontreponemal serologic results. All patients responded rapidly to neurosyphilis therapy. One patient subsequently relapsed after neurosyphilis therapy, and a second was reinfected with recurrence of ocular involvement. One previously undescribed retinal manifestation was discovered: a sectorial retinochoroiditis with delayed retinal circulation in the involved area. Ocular syphilis is a form of neurosyphilis and requires neurosyphilis therapy regardless of when it develops after primary infection. Conventional syphilis staging is of little use in understanding ocular syphilis. A high suspicion for this diagnosis is appropriate, especially in poorer black males with posterior segment inflammatory disease. Human immunodeficiency virus coinfection with ocular syphilis is common, but does not affect response to a neurosyphilis regimen of penicillin in the short term. Awareness of the multiple presentations of posterior segment ocular syphilis will aid ophthalmologists in averting misdiagnosis or delayed diagnosis.

Objective We examined the impact of a combination of home environmental interventions and nurse case management services on total settled dust loadings and on allergen concentrations in the homes of asthmatic children. Methods Using a randomized longitudinal controlled trial study design, we randomly assigned homes of asthmatic children in Milwaukee to either a control (n=64) or an intervention (n=57) group. Control group homes received a visual assessment, education, bed/pillow dust mite encasings, and treatment of lead-based paint hazards. The intervention group received these same services plus nurse case management that included tailored, individual asthma action plans, provision of minor home repairs, home cleaning using special vacuuming and wet washing, and integrated pest management. Dust vacuum samples were collected from measured surface areas of floors in the TV room, kitchen, and child's bedroom at baseline and at three-, six-, and 12-month follow-up visits. Dust loading (mass per surface area) is a means of measuring total dust and the total amount of allergen present. Results For the intervention group, geometric mean dust loadings declined significantly from baseline (39 milligrams per square foot [mg/ft2]) to post-intervention (11 mg/ft2) (p<0.001). Baseline dust loading, treatment group, visit, and season were significant predictors of follow-up dust loadings. Mean post-intervention dust loadings were 72% higher in the control group. The total amount of allergen in settled house dust declined significantly following the intervention because total dust loading declined; the concentration of allergens in settled dust did not change significantly. Conclusion The combination of nurse case management and home environmental interventions promotes collaboration between health and housing professionals and is effective in reducing exposures to allergens in settled dust.

Causation and management of calcific tendonitis and periarthritis.

PubMed

Carcia, Christopher R; Scibek, Jason S

2013-03-01

The purpose of this review is to update the reader on contemporary theory related to the cause of calcific periarthritis and provide the latest evidence associated with treating recalcitrant cases. Contemporary theory suggests calcific periarthritis is the result of a cellular-mediated process in which calcium is deposited and resorbed via a multiple phase process. Resorption is associated with an acute inflammatory response and is often the factor that prompts one to seek medical care. The majority of cases require nothing more than a combination of symptomatic care and benign neglect. A small percentage of cases require intervention to further stimulate deposit resorption. Moderate evidence exists for extracorporeal shock wave therapy in the treatment of chronic cases related to deposits about the shoulder. Numerous case studies support the use of NSAIDs as an effective intervention for retropharyngeal periarthritis. If conservative interventions fail, surgery appears to be a viable option for symptom relief associated with rotator cuff calcific deposits. Periarthritis is typically a symptom-limiting condition that resolves spontaneously. Numerous conservative treatment modalities each with varying levels of evidence exist for use in refractory cases. Future study is necessary to further refine the efficacy and parameters associated with available interventions.

Effects of surgical intervention on trochlear remodeling in pediatric patients with recurrent patella dislocation cases.

Sugimoto, Dai; Christino, Melissa A; Micheli, Lyle J

2016-07-01

Patella instability is often encountered among physically active pediatric athletes, and surgical intervention is useful in cases with recurrent patella dislocations, chronic instability, and abnormal alignment. Several surgical procedures have been used for patella-realignment and stabilization, but the effects of surgical intervention on bony trochlear remodeling in skeletally immature patients have not been well studied. We thus present two cases of pediatric recurrent patella dislocations that showed trochlear remodeling following patella-realignment surgery. The first case describes an 11-year-old female treated with a Roux-Golthwait procedure and the second case highlights a 12-year-old male treated with lateral release and medial capsular reefing. The Merchant technique, a radiographic criterion that was designed to evaluate patella alignment in relation to the femoral trochlea groove, including sulcus and congruence angles was used to measure postoperative bony development. Both pediatric patients showed successful outcomes following surgical interventions for chronic patella instability. Using the Merchant technique, both patients showed improved congruence and sulcus angles postoperatively. Patella realignment in skeletally immature patients may be beneficial for promoting trochlear remodeling and deepening of the trochlear groove, which may help protect against future dislocation or subluxation events.

We report two cases of extrahepatic portal vein aneurysm, and both of them underwent surgical intervention. The first case had a mild pain in right upper quadrant of the abdomen; the second had no obvious symptoms. Physical examination revealed nothing abnormal. Both of them were diagnosed by magnetic resonance imaging angiography (MRA). One of the aneurysms was located at the main portal vein, the other, at the confluence of the superior mesenteric vein and the splenic vein, and these two places are exactly the most common locations of the extrahepatic portal vein aneurysm reported in the literature (30.7% each site). The first case underwent aneurysmorrhaphy and the second case, aneurysm resection with splene-ctomy. Both of them recovered soon after the operation, and the symptom of the first case was greatly alleviated. During the follow-up of half a year, no complication and adverse effect of surgical intervention was found and the color Doppler ultrasonography revealed no recurrence of the aneurysmal dilation. We suggest that surgical interv-ention can alleviate the symptom of the extrahepatic portal vein aneurysm and prevent its complications effectively and safely for low risk patients. PMID:15810096

Aneurysms in Behcet's disease are rare, serious, and recurrent. To achieve durable treatment, patients should receive immunosuppressive therapy before intervention to induce remission. We present early and long-term results of emergency cases of active Behcet's disease, which did not permit waiting for suppressive treatment. The study was undertaken on all cases admitted to the vascular unit, King Fahd Hospital of University for aneurysm treatment in patients with active Behcet's disease over about 10 years. All patients had exclusion of the aneurysm either by open surgery or endovascular intervention. Morbidities and mortality were recorded within the hospital admission and on the follow-up. During the study period, three cases were included. All interventions were successful and lifesaving. However, two cases, treated with surgical interposition grafts, were blocked in the intermediate term follow-up (2-12 months) and one case, treated with endovascular treatment, complicated with pseudoaneurysm at femoral puncture site after six months. Although early results were good, intermediate ones were not satisfactory because of progressive graft thrombosis and formation of new aneurysms. Awareness of these rare cases help for early identification and proper immunosuppressive before emergency vascular intervention is warranted. © The Author(s) 2015.

Background In Afghanistan, improving TB case detection remains challenging. In 2014, only half of the estimated incident TB cases were notified, and notifications have decreased since peaking in 2007. Active case finding has been increasingly considered to improve TB case notifications. While access to health services has improved in Afghanistan, it remains poor and many people seeking health services won’t receive proper care. Methods From October 2011 through December 2012 we conducted three separate case finding strategies in six provinces of Afghanistan and measured impact on TB case notification. Systematically screening cough among attendees at 47 health facilities, active household contact investigation of smear-positive index TB patients, and active screening at 15 camps for internally displaced people were conducted. We collected both intervention yield and official quarterly notification data.

Results We screened 2,022,127 people for TB symptoms during the intervention, tested 59,838 with smear microscopy and detected 5,046 people with smear-positive TB. Most cases (81.7%, 4,125) were identified in health facilities while nearly 20% were found through active case finding. A 56% increase in smear-positive TB notifications was observed between the baseline and intervention periods among the 47 health facilities, where cases detected by all three strategies were notified. Discussion While most people with TB are likely to be identified through health facility screening, there are many people who remain without a proper diagnosis if outreach is not attempted. This is especially true in places like Afghanistan where access to general services is poor. Targeted active case finding can improve the number of people who are detected and treated for TB and can push towards the targets of the Stop TB Global Plan and End TB Strategy. PMID:27701446

In Afghanistan, improving TB case detection remains challenging. In 2014, only half of the estimated incident TB cases were notified, and notifications have decreased since peaking in 2007. Active case finding has been increasingly considered to improve TB case notifications. While access to health services has improved in Afghanistan, it remains poor and many people seeking health services won't receive proper care. From October 2011 through December 2012 we conducted three separate case finding strategies in six provinces of Afghanistan and measured impact on TB case notification. Systematically screening cough among attendees at 47 health facilities, active household contact investigation of smear-positive index TB patients, and active screening at 15 camps for internally displaced people were conducted. We collected both intervention yield and official quarterly notification data. Additional TB notifications were calculated by comparing numbers of cases notified during the intervention with those notified before the intervention, then adjusting for secular trends in notification. We screened 2,022,127 people for TB symptoms during the intervention, tested 59,838 with smear microscopy and detected 5,046 people with smear-positive TB. Most cases (81.7%, 4,125) were identified in health facilities while nearly 20% were found through active case finding. A 56% increase in smear-positive TB notifications was observed between the baseline and intervention periods among the 47 health facilities, where cases detected by all three strategies were notified. While most people with TB are likely to be identified through health facility screening, there are many people who remain without a proper diagnosis if outreach is not attempted. This is especially true in places like Afghanistan where access to general services is poor. Targeted active case finding can improve the number of people who are detected and treated for TB and can push towards the targets of the Stop TB Global Plan and End TB Strategy.

Radiopharmaceutical extravasation can potentially lead to severe soft tissue damage, but little is known about incidence, medical consequences, possible interventions, and effectiveness of these. The aims of this study are to estimate the incidence of extravasation of diagnostic and therapeutic radiopharmaceuticals, to evaluate medical consequences, and to evaluate medical treatment applied subsequently to those incidents. A sensitive and elaborate literature search was performed in Embase and PubMed using the keywords "misadministration", "extravasation", "paravascular infiltration", combined with "tracer", "radionuclide", "radiopharmaceutical", and a list of keywords referring to clinically used tracers (i.e. "Technetium-99m", "Yttrium-90"). Reported data on radiopharmaceutical extravasation and applied interventions was extracted and summarised. Thirty-seven publications reported 3016 cases of diagnostic radiopharmaceutical extravasation, of which three cases reported symptoms after extravasation. Eight publications reported 10 cases of therapeutic tracer extravasation. The most severe symptom was ulceration. Thirty-four different intervention and prevention strategies were performed or proposed in literature. Extravasation of diagnostic radiopharmaceuticals is common. 99m Tc, 123 I, 18 F, and 68 Ga labelled tracers do not require specific intervention. Extravasation of therapeutic radiopharmaceuticals can give severe soft tissue lesions. Although not evidence based, surgical intervention should be considered. Furthermore, dispersive intervention, dosimetry and follow up is advised. Pharmaceutical intervention has no place yet in the immediate care of radiopharmaceutical extravasation.

An enhanced employee assistance program (EAP) intervention was developed that delivers comprehensive EAP outreach services to all employees who may have alcohol-related and other workplace problems; standard EAP materials traditionally targeted at white men were enhanced to include women and minorities. This study evaluates whether the enhanced EAP intervention increased EAP utilization. The enhanced EAP intervention was developed at a large community-based not-for-profit EAP located in Rockford, Illinois. Two primary worksites and 16 other newly contracted worksites received the enhanced EAP intervention and served as intervention sites; the 107 other worksites serviced by the EAP were used as comparison sites. We used time series data from 1991 to 1998 and included repeated measures on each firm's quarterly EAP utilization. The enhanced EAP intervention increased the mean number of women and minority cases per worksite by 58%, white male cases by 45% and total EAP cases by 53%. This study shows that, for a modest cost, the enhanced EAP intervention successfully increased utilization of EAP by all employees, especially utilization by women and minority employees. It also shows that traditional EAP services and outreach materials can be made more appealing to women and minorities without adversely affecting their utilization by white men.

Applying social constructionism in the treatment of patients who are intractably aggressive.

PubMed

Caldwell, M F

1994-06-01

Interventions based on the philosophy of social constructionism can be used for the treatment of patients who are intractably aggressive. The interventions are aimed at disrupting common interactive patterns between the patient and treaters in the treatment milieu and replacing them with patterns that do not allow the intractable symptoms to disrupt treatment efforts. Two case examples illustrate the use of this approach with extremely violent inpatients with long histories of unsuccessful interventions. In both cases the treatment included discontinuing certain therapeutic or prosocial interventions; one case involved determining the patient's daily privilege level randomly. The author discusses the advantages and difficulties of such approaches, including the need for staff to reframe their own logical structure and to overcome resistance from different levels of the treatment system.

Dengue is a serious public health problem with an important economic impact. This study used data from a cluster randomised controlled trial of community mobilisation for dengue prevention to estimate the household costs of treatment of dengue illness. It examined the economic impact of the trial intervention in the three coastal regions of Mexico's Guerrero State. The 2010 baseline survey covered households in a random sample of 90 clusters in the coastal regions; the clusters were randomly allocated to intervention or control and re-surveyed in 2012. The surveys asked about dengue cases in the last 12 months, expenditures on their treatment, and work or school days lost by patients and care givers. We did not assign monetary value to days lost, since a lost day to a person of low earning power is of equal or higher value to that person than to one who earns more. The 12,312 households in 2010 reported 1020 dengue cases in the last 12 months (1.9% of the sample population). Most (78%) were ambulatory cases, with a mean cost of USD 51 and 10.8 work/school days, rising to USD 96 and 11.4 work/school days if treated by a private physician. Hospitalised cases cost USD 28-94 in government institutions and USD 392 in private hospitals (excluding additional inpatient charges), as well as 9.6-17.3 work/school days. Dengue cases cost households an estimated 412,825 work/school days throughout the three coastal regions. In the follow up survey, 6.1% (326/5349) of households in intervention clusters and 7.9% (405/5139) in control clusters reported at least one dengue case. The mean of days lost per case was similar in intervention and control clusters, but the number of days lost from dengue and all elements of costs for dengue cases per 1000 population were lower in intervention clusters. If the total population of the three coastal regions had received the intervention, some 149,401 work or school days lost per year could have been prevented. The economic effect of dengue on households, including lost work days, is substantial. The Camino Verde trial intervention reduced household costs for treatment of dengue cases. The trial was registered as ISRCTN:27,581,154 .

Social Comparison Framing in Health News and Its Effect on Perceptions of Group Risk

PubMed Central

Bigman, Cabral A.

2013-01-01

News about health disparities often compares health risks faced by different demographic groups. Does this social comparison produce a contrast effect? It was hypothesized that when two racial groups are compared, people would perceive the relatively more at-risk group to be more, and the less at-risk group to be less, at-risk than if the same risk information was presented without the comparative reference group. Three experiments with Black and White respondents tested effects of intergroup social comparison framing (SCF) on perceptions of risk for sexually transmitted infections and skin cancer. SCF (including one White and two Black disparity frames) did not raise respondents’ perceived risk regarding the more at-risk racial group, but consistently lowered respondents’ risk ratings for the less at-risk racial group. The finding that the same statistic was perceived differently in comparative and non-comparative contexts underscores the importance of considering effects of communication about disparities.

2003-06-01

To document the clinical efficacy and tolerability of itopride hydrochloride in patients with non-ulcer dyspepsia an open-label, non-comparative study, was undertaken at the Medical College, Thiruvananthapuram, among patients with endoscopically confirmed diagnosis of non-ulcer dyspepsia or chronic gastritis. Itopride hydrochloride 50 mg (1 tablet) thrice a day for 2 weeks was administered among them. Relief of symptoms at the end of two weeks treatment, assessed as marked/complete, moderate, slight, none or worse; QT interval on ECG; adverse events; haemogram; serum chemistry for hepatic and renal functions. None had QT prolongation on ECG. At the end of 2 weeks' treatment, moderate to complete relief of symptoms was reported by 22 patients (73%), whereas 5 (17%) reproted slight improvement, and 3 (10%) reported no improvement. Clinical tolerability was excellent in 28 patients (93%) and good in 2 (7%). None of the patients had any prolongation of QT on ECG, nor did any patient show any abnormality in haemogram or serum chemistry during the treatment.

Linezolid may be an interesting alternative for prosthetic joint infection (PJI) due to its bioavailability and its antimicrobial spectrum. However, experience in this setting is scarce. The aim of the study was to assess linezolid's clinical and microbiological efficacy, and also its tolerance. This was a prospective, multicenter, open-label, non-comparative study of 25 patients with late-chronic PJI caused by Gram-positive bacteria managed with a two-step exchange procedure plus 6 weeks of linezolid. Twenty-two (88%) patients tolerated linezolid without major adverse effects, although a global decrease in the platelet count was observed. Three patients were withdrawn because of major toxicity, which reversed after linezolid stoppage. Among patients who completed treatment, 19 (86%) demonstrated clinical and microbiological cure. Two patients presented with clinical and microbiological failure, and one showed clinical cure and microbiological failure. In conclusion, linezolid showed good results in chronic PJI managed with a two-step exchange procedure. Tolerance seems acceptable, though close surveillance is required.

Clinical outcomes with daptomycin: a post-marketing, real-world evaluation.

PubMed

Sakoulas, G

2009-12-01

The Cubicin Outcomes Registry and Experience (CORE) is an ongoing, retrospective, post-marketing database of daptomycin use in the USA. Although non-comparative, CORE offers insight into real-life clinical experience with daptomycin in various Gram-positive infections and specific patient types. Analyses of daptomycin treatment outcomes using the CORE database revealed that treatment with daptomycin has resulted in high rates of clinical success for a variety of Gram-positive infections, including indicated infections such as complicated skin and soft tissue infections, Staphylococcus aureus bacteraemia and right-sided infective endocarditis, and non-indicated infections such as osteomyelitis. Treatment outcomes did not differ significantly according to the causative pathogen for any of the analyses performed and were not influenced by the vancomycin MIC. Patients frequently received therapy with alternative antibiotics prior to treatment with daptomycin, particularly those patients with more serious infections. However, similar treatment outcomes were observed when daptomycin was used as first-line therapy or as salvage therapy, demonstrating the effectiveness of daptomycin in the treatment of these patients.

2014-03-01

We investigated whether patients with obsessive-compulsive disorder have poorer memory and executive functions than healthy controls. The relatively inconsistent previous findings on this question reflect a lack of well-matched control groups, the inclusion of patients with comorbidity, and the use of noncomparable neuropsychological tests to assess memory and executive functions. We used well-accepted neuropsychological tests of memory and executive functions to assess 42 patients who had obsessive-compulsive disorder without comorbidity, and 42 healthy controls. We matched the patients and controls pairwise by sex, age, and years of education. The patients performed significantly worse than the controls on the Rey Complex Figure Test, which assesses visuospatial memory and organizational skills. This group difference remained after we controlled for age, education, intelligence, and severity of depressive symptoms. The findings indicate that patients with obsessive-compulsive disorder may have impaired visuospatial memory and organizational skills, and these impairments should be considered in treatment.

The aim of this paper is to present the assessment of a case management project, implemented with chronic patients in Valencia, for the integration of health and social care. This project is linked with the 'Sustainable Socio-Health Model'. Health department 06 in Valencia. The target groups were chronic patients of 65 years and over. A non-randomized non-blinded comparative study with an intervention and control group. The intervention consisted in the creation of an interdisciplinary case management team, the use of a common portfolio of resources, and its application to a pilot sample with an intervention period of 6-9 months. Diseases (ICD-9), functional capacity, use of health and social resources, satisfaction, unit cost services. There was an increase in the combined use of health and social resources in the intervention group, which included social day centers (21.8% in the intervention group compared to 9.8% in the control group), in coordination with primary care (suggested as the only health resource in 55.4% of cases). There was a decrease in the number of medical visits in the intervention group (43.6% versus 74.5% in the control group). Increased patient satisfaction (55.5% in the intervention group compared to 29.4% in the control group) was observed. At least an extra 4.4% of patients were treated using hospital resources without increasing costs. Case management using a common unique portfolio of health and social resources can improve the coordination of resources, increases patient satisfaction and increases the capacity of using of hospital resources.

Self-expandable metal stent (SEMS) implantation may rapidly improve the symptoms of malignant esophageal stenosis and tracheoesophageal fistulas (TEF). However, dysphagia often returns subsequently and repeated endoscopic intervention may be necessary. The aims of the study were to identify the risk factors of complications, and the frequency and efficacy of repeated endoscopic interventions; and to provide technical recommendations on appropriate stent selection. We analyzed retrospectively the clinical data of 212 patients with locally advanced esophageal cancer who underwent SEMS implantation. A total of 238 SEMS implantations were performed with 99.06% technical success and 1.26% procedure-related deaths in the enrolled 212 cases. Complications occurred in 84 patients (39.62%) and in 55 cases (25.94%) repeated endoscopic procedures were required. Early reintervention 24-48 h after the stent implantations was necessary due to stent migration (12 cases), arrhythmia (2 cases), intolerable retrosternal pain (1 case) and dyspnea (1 case). An average of 1.98 repeated gastroscopies (range 1-6; median 2), 13.58 weeks (range 1.5-48; median 11) after the stent implantation were performed during the follow-up period: 37 stent repositions, 23 restent implantations, 15 endoscopic esophageal dilations and 7 stent removals. In 48 cases (87.3%) oral feeding of patients was made possible by endoscopic interventions. In a quarter of SEMS implantations, complications occur that can be successfully managed by endoscopic interventions. Our experiences have shown that individualized stent choice may substantially reduce the complications rate and make repeated endoscopic interventions easier.

[Early hypertrophic scar after surgery on the nasal region: value of long-acting corticosteroid injections].

PubMed

Amici, J-M

2014-01-01

"Pincushioning" is a complication of post-surgical scarring following use of transposition flaps particularly when surgery is performed on the nasal region. The transposition flap technique is very useful for the repair of certain defects of the tip of the nose, the medial canthus or of the ala nasi. The aim of this study is to define the clinical characteristics of this scarring dystrophy, which we propose to call "early hypertrophy scarring", to clarify the nature thereof and to assess the efficacy of intralesional injection of corticosteroids at the first signs of hypertrophy. A prospective, open, non-comparative, single-centre study examined the clinical and histological characteristics of early hypertrophy scarring and the effectiveness of therapy with one or two injections of corticosteroids performed on the 15th day post-operatively and optionally repeated at D45 depending on the outcome. From January 2011 to January 2013, 12 consecutive patients with early hypertrophy scarring were included (ten men and two women - mean age: 64 years). All had undergone surgery for basal cell carcinoma under local anaesthesia with one-stage repair by means of a rhombic flap or a bilobed flap located in the nasal area. Scars were injected strictly intra-lesionally with triamcinolone acetate (40 mg/1 mL) until whitening occurred. A single injection was performed in three cases of rhombic flap while a second injection was given at D45 in the remaining nine cases. Complete regression of the early hypertrophy scarring was obtained in ten of the 12 patients by D90. Incomplete regression was observed but with a marked improvement in the other two patients. Early hypertrophy scarring is distinguished by its clinical characteristics of hypertrophic or keloid scars. Biopsy performed in two cases showed the fibrous but non-fatty nature of early hypertrophy scarring. Biomechanical factors particular to the nasal region and the transposition flap technique could account for the early and excessive collagen production causing early hypertrophy scarring. Early injection of corticosteroids, which was consistently effective in our study, could represent a simple treatment for early hypertrophy scarring, thus avoiding surgical correction. These preliminary results in a small number of patients require confirmation by a comparative, multicentre, prospective controlled study. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Attachment and Biobehavioral Catch-Up (ABC) is an intervention designed for vulnerable children and their parents. This intervention enhances parental sensitivity and nurturance with the goal of promoting secure, organized attachments and strong self-regulatory capabilities among children. Here, we provide a brief rationale for the need for such interventions to be delivered to parent-child dyads in the child welfare system. Next, we review specific intervention targets of ABC. We include a case example of two birth parents and their daughter who became involved in Child Protective Services due to domestic violence. © 2018 Wiley Periodicals, Inc.

Assessing the Effectiveness of On-Farm and Abattoir Interventions in Reducing Pig Meat-Borne Salmonellosis within E.U. Member States.

As part of the evidence base for the development of national control plans for Salmonella spp. in pigs for E.U. Member States, a quantitative microbiological risk assessment was funded to support the scientific opinion required by the EC from the European Food Safety Authority. The main aim of the risk assessment was to assess the effectiveness of interventions implemented on-farm and at the abattoir in reducing human cases of pig meat-borne salmonellosis, and how the effects of these interventions may vary across E.U. Member States. Two case study Member States have been chosen to assess the effect of the interventions investigated. Reducing both breeding herd and slaughter pig prevalence were effective in achieving reductions in the number of expected human illnesses in both case study Member States. However, there is scarce evidence to suggest which specific on-farm interventions could achieve consistent reductions in either breeding herd or slaughter pig prevalence. Hypothetical reductions in feed contamination rates were important in reducing slaughter pig prevalence for the case study Member State where prevalence of infection was already low, but not for the high-prevalence case study. The most significant reductions were achieved by a 1- or 2-log decrease of Salmonella contamination of the carcass post-evisceration; a 1-log decrease in average contamination produced a 90% reduction in human illness. The intervention analyses suggest that abattoir intervention may be the most effective way to reduce human exposure to Salmonella spp. However, a combined farm/abattoir approach would likely have cumulative benefits. On-farm intervention is probably most effective at the breeding-herd level for high-prevalence Member States; once infection in the breeding herd has been reduced to a low enough level, then feed and biosecurity measures would become increasingly more effective. © 2016 Society for Risk Analysis.

The Public Health Intervention Wheel (PHIW) is a population-based practice model that encompasses three levels of practice (community, systems, and individual/family) and 17 public health interventions. Each intervention and practice level contributes to improving population health. Public health nurses (PHNs) provide care at the three levels of practice. Prevention of falls is a public health issue and the majority of falls happen at home. Therefore, prevention and management of falls in the community could benefit from a public health systems approach by PHNs underpinned by the PHIW. A hypothetical case is presented of a 78-year-old gentleman who had a fall which resulted in a fractured right acetabulum and surgery before being discharged home. The aim of this paper was to use a case summary to illustrate PHN practice in the context of the PHIW as applied to falls management and prevention. This paper focuses on fall incidence and PHN response in Ireland and Norway. The PHIW is described and relevant interventions from the PHIW are applied to PHN practice in managing the case. The PHIW model provides insight into the potential scope of public health nursing in falls, articulating PHN practice in the community. © 2018 Wiley Periodicals, Inc.

Many individuals with autism cannot speak or cannot speak intelligibly. A variety of aided augmentative and alternative communication (AAC) approaches have been investigated. Most of the research on these approaches has been single-case research, with small numbers of participants. The purpose of this investigation was to meta-analyze the single case research on the use of aided AAC with individuals with autism spectrum disorders (ASD). Twenty-four single-case studies were analyzed via an effect size measure, the Improvement Rate Difference (IRD). Three research questions were investigated concerning the overall impact of AAC interventions on targeted behavioral outcomes, effects of AAC interventions on individual targeted behavioral outcomes, and effects of three types of AAC interventions. Results indicated that, overall, aided AAC interventions had large effects on targeted behavioral outcomes in individuals with ASD. AAC interventions had positive effects on all of the targeted behavioral outcome; however, effects were greater for communication skills than other categories of skills. Effects of the Picture Exchange Communication System and speech-generating devices were larger than those for other picture-based systems, though picture-based systems did have small effects.

With the shortage of donor hearts, increasingly more patients with end-stage heart failure are implanted with left ventricular assist devices (LVADs). LVADs are associated with a significant risk of developing acute ischemic strokes (AISs). Very little is known on about the management of AIS in patients with LVAD, especially with regard to the safety and efficacy of neuroendovascular techniques. We identified 5 patients with heart failure and LVAD implants who developed AIS and underwent neuroendovascular interventions at Columbia University Medical Center. Their cases were reviewed for the safety, efficacy of the interventions, and potential complications. There were no significant complications from the interventions. In all 5 cases, there was at least a 4-point improvement in the National Institutes of Health Stroke scale and none of the cases developed symptomatic hemorrhage. Two patients had substantial improvement and received cardiac transplantations. Neuroendovascular intervention is safe and feasible in patients with LVAD and may potentially contribute to improving the outcome of a disease that has a poor natural history. Further study is recommended. Copyright © 2016 Elsevier Inc. All rights reserved.

Accidental swallowing of hijab (or turban) pin was reported mainly among adolescent girls. Current guidelines indicate emergent intervention endoscopy in case a long sharp object is found in the gastrointestinal tract. The aims of the current study are to present the results of an observational approach and to assess the need for intervention. A retrospective cohort study was conducted including all 5-18-year-old patients who presented with hijab-pin ingestion between 2003 and 2014. The need for intervention was assessed using both univariable and multivariable statistical analyses. Two hundred three cases of hijab-pin ingestion were documented. In the majority of cases, the pin was observed in the stomach (137/203, 67.4%) upon arrival. Most pins that were located at the upper gastrointestinal tract (proximal to the ligament of Treitz) ejected spontaneously (120/169, 71%, Pv = 0.005). The absence of pin progression in an X-ray performed 12 h following presentation was significantly more frequent in the intervention group (46/51, 90%, Pv = 0.001). In most cases, the outcome is spontaneous ejection from the digestive tract. However, if needle location remains unchanged on two consecutive X-rays, an endoscopic intervention is recommended.

Correlation between Hemodynamics and Treatment Outcome of Intracranial Aneurysms after Intervention with Flow Diverters

Endovascular intervention by Flow Diverter (FD) - a densely woven stent - occludes an aneurysm by inducing thrombosis in the aneurysm sac and reconstructing the vessel. Hemodynamics plays a vital role in the thrombotic occlusion of aneurysms and eventual treatment outcome. CFD analysis of pre- and post-treatment aneurysms not only provides insight of flow modifications by FD, but also allows investigation of interventional strategies and prediction of their outcome. In this study 80 patient-specific aneurysms treated with FDs were retrospectively studied to evaluate the effect of intervention. Out of these cases, 16 required retreatment and thus are considered as having unfavorable outcome. Clinical FD deployment in these cases was simulated using an efficient virtual stenting workflow. CFD analysis was carried out on both pre- and post-treatment cases, and changes in hemodynamic parameters were calculated. Support vector machine algorithm was used to correlate the hemodynamic changes with outcome. Results show that cases having higher flow reduction into the aneurysmal sac have a better likelihood of occlusion. This suggests that changes in hemodynamics can be potentially used to predict the outcome of different clinical intervention strategies in aneurysms. This work was supported by the National Institutes of Health (R01 NS091075).

Objective. To determine the degree to which 3 different educational interventions enhance cultural competency in pharmacy students. Methods. Students were equally divided among a simulated-patient activity group, a written case-scenarios group, and a formal lecture group. Mean scores for pre- and post-intervention cultural self-assessment surveys were compared. Results. In the simulation group, there were significant positive changes in the cultural skills and cultural desire components; in the case-scenario group, there was a significant positive change in the cultural awareness component; and in the lecture group, there were significant positive changes in the cultural skills and cultural empathy components. With respect to the cultural skills component, there was greater post-intervention improvement in the simulation and lecture groups than in the case-scenario group. Conclusions. There were significant positive changes within each group, indicating that ideologies and behaviors may be altered based on the educational intervention received. However, a 1-hour practicum may not be sufficient to enhance cultural competency. PMID:23716744

Aggression is common in Huntington's disease. However, at present there are no standard guidelines for managing aggression in Huntington's sufferers due to a lack of empirical research. This paper presents a case study of the treatment of very high levels of aggression with sensory modulation and behaviour support intervention in a Huntington's sufferer. The client exhibited a range of aggressive behaviours, including physical aggression to people, furniture and objects, and verbal aggression. Following an eight week baseline phase, five weeks of sensory modulation intervention were employed. A behaviour support plan was then implemented as an adjunct to the sensory intervention, with aggressive behaviour systematically audited for a further 11 weeks. The results indicate a significant reduction in reported levels of aggression during the combined sensory modulation and behaviour support phase, compared to both the baseline and the sensory modulation therapy alone phases. This case study highlights the efficacy non-pharmacological interventions may have for reducing aggression in HD.

Measles transmission from an anthroposophic community to the general population, Germany 2008

PubMed Central

2011-01-01

Background In Germany, measles vaccination coverage with two doses is not yet sufficient to prevent regional outbreaks. Among the 16 German federal states, vaccination coverage was lowest in Bavaria with 85% in 2008. From March to mid-April 2008, four neighbouring Bavarian counties reported 55 measles-cases mostly linked to an ongoing measles outbreak in an anthroposophic school in Austria. We investigated this outbreak to guide future public health action. Methods We applied the German national case-definition for measles and collected data using the national surveillance system and a questionnaire. Measles cases with disease onset a maximum of 18 days apart and spatial contact (e.g. same household, same school) were summed up in clusters. Two different interventions, which were implemented in schools and kindergartens in Bavaria, were compared by their impact on the size and duration of measles clusters. Susceptible persons were excluded from schools or kindergartens either with the first (intervention A) or second (intervention B) measles case occurring in the respective institution. Results Among the 217 Bavarian measles cases identified from March-July 2008, 28 (13%) cases were attendees of the anthroposophic school in Austria. In total, vaccination status was known in 161 (74%) cases and 156 (97%) of them were not vaccinated. The main factor for non-vaccination was "fear of vaccine-related adverse events" (33%). Twenty-nine (18%) of 161 cases suffered complications. Exclusively genotype D5 was detected. Overall, 184 cases could be epidemiologically grouped into 59 clusters. Of those, 41 clusters could be linked to households and 13 to schools or kindergartens. The effect of intervention A and B was analysed in 10 school or kindergarten clusters. Depending on the respective intervention A or B, the median number of cases per cluster was 3 versus 13 (p = 0.05), and the median duration of a cluster was 3 versus 26 days (p = 0.13). Conclusions Introduction of measles virus into a pocket of susceptible persons (e.g. vaccination opponents or sceptics) may lead to large outbreaks in the general population, if the general population's vaccination coverage is below the WHO recommended level. Education on the safety of measles vaccine needs to be strengthened to increase measles vaccination coverage. Early intervention may limit spread in schools or kindergartens. Suspected measles has to be reported immediately to the local health authorities in order to allow intervention as early as possible. PMID:21676265

Background Previous research demonstrated efficacy of a brief behavioral intervention to reduce incidence of HIV and sexually transmitted infections (STIs) among female sex workers (FSWs) in Tijuana and Ciudad Juarez, Mexico, cities on Mexico's border with the US. We assessed this intervention's cost-effectiveness. Methodology and Principal Findings A life-time Markov model was developed to estimate HIV cases prevented, changes in quality-adjusted life expectancy (QALE), and costs per additional quality-adjusted life year gained (QALY), comparing (in US$2,009) no intervention to a once-only and annual intervention. Future costs and health benefits were discounted annually at 3%. Sensitivity analyses evaluated model robustness. We found that for a hypothetical 1,000 FSWs receiving the once-only intervention, there were 33 HIV cases prevented and 5.7 months of QALE gained compared to no intervention. The additional cost per QALY gained was US$183. For FSWs receiving the intervention annually, there were 29 additional HIV cases prevented and 4.5 additional months of QALE compared to the once-only intervention. The additional cost per QALY was US$1,075. When highly active antiretroviral therapy (HAART) was included in the model, the annual intervention strategy resulted in net savings and dominated both once-only and no intervention strategies, and remained robust across extensive sensitivity analyses. Even when considering clinical benefits from HAART, ignoring added costs, the cost per QALY gained remained below three times the Mexican GDP per capita, and below established cost-effectiveness thresholds. Conclusions/Significance This brief intervention was shown to be cost-effective among FSWs in two Mexico-US border cities and may have application for FSWs in other resource-limited settings.

The present study evaluates the use of a laser guidance system for CT-guided intervention. 94 cases of diagnostic biopsies and lumbar sympathectomies (54 cases with laser guidance system and 40 without) were compared. Using the laser guidance system, the number of control scans decreased by 30 to 50%, and necessary corrections of needle location were reduced by a maximum of 30%. The average target deviation of the needle decreased to less than 5 mm in 50% of cases. The laser guidance system is strongly recommended in CT-guided interventions for quality assurance and higher efficiency. The advantage is especially marked if the target area is small.

This case study illustrates the characteristics of the nursing diagnosis readiness for enhanced self health management. Published literature, experience, and expertise of the author were utilized as data sources. The standardized nursing languages of NANDA International, Nursing Outcomes Classification, Nursing Interventions Classification, and interventions related to the client's management of diabetes were derived for the case study. The use of standardized nursing languages with interventions related to the management of type 2 diabetes provided a framework for nurses to support clients with enhanced self-management to improve their outcomes. The use of standardized nursing language in the management of type 2 diabetes can improve client outcomes.

Objective We describe cognitive-behavioral therapy for bulimia nervosa (CBT-BN) with a Latina woman that incorporates culturally relevant topics. Method A single case report of a 31-year-old monolingual Latina woman with BN describes the application of a couple-based intervention adjunctive to CBT-BN. Results The patient reported no binge and purge episodes by session 20 and remained symptom free until the end of treatment (session 26). Improvement was observed in the Eating Disorders Examination (EDE) comparing baseline (EDE=5.74) with post treatment (EDE=1.25). Conclusions The case illustrates how cultural adaptations such as including a family member, being flexible on topics and scheduling, and providing culturally relevant interventions can lead to successful completion of a course of therapy and facilitate ongoing interventions to ensure continued recovery.

In recent years, veterinary education has received an increased amount of attention directed at the value and application of collaborative case-based learning. The benefit of instilling deep learning practices in undergraduate veterinary students has also emerged as a powerful tool in encouraging continued professional education. However, research into the design and application of instructional strategies to encourage deep, collaborative case-based learning in veterinary undergraduates has been limited. This study focused on delivering an instructional intervention (via a 20-minute presentation and student handout) to foster productive, collaborative case-based learning in veterinary education. The aim was to instigate and encourage deep learning practices in a collaborative case-based assignment and to assess the impact of the intervention on students' group learning. Two cohorts of veterinary students were involved in the study. One cohort was exposed to an instructional intervention, and the other provided the control for the study. The instructional strategy was grounded in the collaborative learning literature and prior empirical studies with veterinary students. Results showed that the intervention cohort spent proportionally more time on understanding case content material than did the control cohort and rated their face-to-face discussions as more useful in achieving their learning outcomes than did their control counterparts. In addition, the perceived difficulty of the assignment evolved differently for the control and intervention students from start to end of the assignment. This study provides encouraging evidence that veterinary students can change and enhance the way they interact in a group setting to effectively engage in collaborative learning practices.

Modeling malaria control intervention effect in KwaZulu-Natal, South Africa using intervention time series analysis.

The change of the malaria control intervention policy in South Africa (SA), re-introduction of dichlorodiphenyltrichloroethane (DDT), may be responsible for the low and sustained malaria transmission in KwaZulu-Natal (KZN). We evaluated the effect of the re-introduction of DDT on malaria in KZN and suggested practical ways the province can strengthen her already existing malaria control and elimination efforts, to achieve zero malaria transmission. We obtained confirmed monthly malaria cases in KZN from the malaria control program of KZN from 1998 to 2014. The seasonal autoregressive integrated moving average (SARIMA) intervention time series analysis (ITSA) was employed to model the effect of the re-introduction of DDT on confirmed monthly malaria cases. The result is an abrupt and permanent decline of monthly malaria cases (w 0 =-1174.781, p-value=0.003) following the implementation of the intervention policy. The sustained low malaria cases observed over a long period suggests that the continued usage of DDT did not result in insecticide resistance as earlier anticipated. It may be due to exophagic malaria vectors, which renders the indoor residual spraying not totally effective. Therefore, the feasibility of reducing malaria transmission to zero in KZN requires other reliable and complementary intervention resources to optimize the existing ones.

The aim of this study was to populate the Equitable Impact Sensitive Tool (EQUIST) framework with all necessary data and conduct the first implementation of EQUIST in studying cost-effectiveness of community case management of childhood pneumonia in 5 low- and middle-income countries with relation to equity impact. Wealth quintile-specific data were gathered or modelled for all contributory determinants of the EQUIST framework, namely: under-five mortality rate, cost of intervention, intervention effectiveness, current coverage of intervention and relative disease distribution. These were then combined statistically to calculate the final outcome of the EQUIST model for community case management of childhood pneumonia: US$ per life saved, in several different approaches to scaling-up. The current 'mainstream' approach to scaling-up of interventions is never the most cost-effective. Community-case management appears to strongly support an 'equity-promoting' approach to scaling-up, displaying the highest levels of cost-effectiveness in interventions targeted at the poorest quintile of each study country, although absolute cost differences vary by context. The relationship between cost-effectiveness and equity impact is complex, with many determinants to consider. One important way to increase intervention cost-effectiveness in poorer quintiles is to improve the efficiency and quality of delivery. More data are needed in all areas to increase the accuracy of EQUIST-based estimates.

Transradial access (TRA) has shown lower morbidity and decreased bleeding complications compared to transfemoral access. This study evaluates the safety and feasibility of TRA in thrombocytopenic patients undergoing visceral interventions. Patients who underwent visceral interventions via the radial artery with platelet count less than or equal to 50,000/µL were included in the study. Outcome variables included technical success, access site, bleeding, transfusion, and neurological complications. From July 1, 2012, to May 31, 2015, a total of 1353 peripheral interventions via TRA were performed, of which 85 procedures were performed in 64 patients (mean age 62.2 years) with a platelet count <50,000/µL (median 39,000/µL). Interventions included chemoembolization (n = 46), selective internal radiation therapy (n = 30), and visceral embolization (n = 9). Technical success was 97.6% with two cases of severe vessel spasm requiring ipsilateral femoral crossover. There was no major access site, bleeding, or neurological adverse events at 30 days. Minor access site hematomas occurred in five cases (5.9%) and were treated conservatively in all cases. Pre-procedural platelet transfusions were administered in 23 (27.1%) cases. There was no statistically significant difference in access site or bleeding complications between the transfused and nontransfused groups. Transradial visceral interventions in patients with thrombocytopenia are both feasible and safe, possibly without the need for platelet transfusions.

Using pharmacokinetic/pharmacodynamic principles, pharmacokinetically enhanced amoxicillin/clavulanate 2000/125 mg twice daily was designed to provide adequate levels of amoxicillin over the 12-h dosing interval to eradicate penicillin-resistant Streptococcus pneumoniae (PRSP, penicillin MICs > or = 2 mg/L) with amoxicillin MICs of at least 4 mg/L. The clinical efficacy of amoxicillin/clavulanate 2000/125 mg was evaluated in patients with respiratory tract infections caused by S. pneumoniae, including isolates with elevated penicillin (2-8 mg/L) MICs. Data from 10 clinical studies were combined: seven randomised (1:1), double-blind, controlled trials (efficacy intent-to-treat [ITT]N = 3376): amoxicillin/clavulanate 2000/125 mg twice daily vs. levofloxacin 500 mg once daily in acute bacterial sinusitis (ABS); levofloxacin 500 mg once daily in acute exacerbations of chronic bronchitis (AECB); clarithromycin 500 mg twice daily in AECB; amoxicillin/clavulanate 875/125 mg twice daily/three times daily and 1000/125 mg three times daily in community-acquired pneumonia (CAP) and three noncomparative studies (efficacy ITT N = 3024): two in ABS, one in CAP. The bacteriological per-protocol (PP) population at follow up (days 14-39) comprised 1295 patients for amoxicillin/clavulanate 2000/125 mg and 241 for comparators. With amoxicillin/clavulanate 2000/125 mg at follow-up, outcome was successful (clinical success and eradication/presumed eradication) in 85/90 (94.4%) patients with S. pneumoniae in comparative studies and 421/445 (94.6%) in noncomparative studies, and with comparators 58/70 (82.9%) were successes. In the amoxicillin/clavulanate 2000/125 mg group at follow up, 52/552 S. pneumoniae isolates were resistant to penicillin. At follow up, 50/52 (96.2%) patients with PRSP were successes, including 6/7 with amoxicillin MICs of 4 mg/L and 7/8 with amoxicillin MICs of 8 mg/L. Success rates for amoxicillin/clavulanate 2000/125 mg against PRSP were similar for CAP (96.0%[24/25]), AECB (100%[3/3]) and ABS (95.8%[23/24]). There were six PRSP isolates in the comparator group (two isolates were from one patient), and three of five patients in this group were successes. In conclusion, amoxicillin/clavulanate 2000/125 mg demonstrated combined clinical/bacteriological success against 50/52 patients with PRSP, including 13/15 strains with amoxicillin MICs of 4-8 mg/L. These results for the pharmacokinetic-enhanced formulation of amoxicillin/clavulanate 2000/125 mg are in line with the high efficacy against PRSP predicted using pharmacokinetic/pharmacodynamic parameters.

Few studies have assessed the efficacy and safety of micafungin in patients with proven or probable invasive aspergillosis (IA). This was the aim of the current study, which was conducted in 22 hospitals in China, where micafungin was approved for treatment of IA in 2006. This was a non-comparative, phase IV open-label study (NCT02646774). Eligible patient were adults with proven or probable IA. Efficacy endpoints included rates of overall treatment success (primary endpoint) and clinical improvement, fungal clearance, mortality, and the site of Aspergillus infection (all secondary endpoints). Safety endpoints included incidences of treatment-emergent adverse events (TEAEs), serious AEs (SAEs), and adverse drug reactions (ADRs). These endpoints were reported descriptively with associated 95% confidence intervals (CI); no hypotheses were tested. The study was discontinued early due to low patient recruitment, which did not allow for the planned sample size to be reached. In total, 68 patients were enrolled: 42 into the full analysis set (for efficacy) and 61 into the safety analysis set. All patients were Han Chinese; the majority were male (n = 26; 61.9%) and ≤60 years of age (n = 35; 83.3%). Rates of overall treatment success, clinical improvement, fungal clearance, and mortality were 45.2% (n = 19/42; 95% CI: 29.85-61.33); 59.5% (n = 25/42; 95% CI: 43.28-74.37), 80.0% (n = 4/5; 95% CI: 28.36-99.49), and 7.1% (n = 3/42; 95% CI: 1.50-19.48), respectively. All patients were diagnosed with pulmonary Aspergillus infection. Overall, 155 TEAEs and 8 SAEs were reported by 37 (60.7%) and 7 (11.5%) patients. The most common TEAEs were decreased platelet count and fatigue (both n = 5; 8.2%) and the most common SAEs were intracranial hemorrhage and lung infection (n = 3; 4.9% and n = 2; 3.3%). Eight ADRs (n = 6; 9.8%) were reported but all were completely remitted or remitting during follow-up. Results suggest that micafungin is efficacious and well-tolerated in patients with proven or probable IA in China. However, these findings should be interpreted with care, due to the small number of patients included in this study. Further comparative trials should be used to confirm the efficacy and safety of micafungin in patients with proven or probable IA. Copyright © 2017 The Authors.

Objective: To optimize the clinical managements of primary fetal hydrothorax (PFHT) fetus by comparing the perinatal survival rate of different prenatal treatments. Methods: Totally 13 fetuses diagnosed with PFHT from July 2009 to December 2015 in the First Affiliated Hospital of Jinan University were collected and received prenatal expectant treatment, thoracocentesis (TC), and thoraco-amniotic shunting (TAS), respectively. The perinatal survival rate was compared among the three treatments. Results: Among 13 fetuses of PFHT, pleural effusion was absorbed or remained stable in 2(2/13) cases, and progressed in 11(11/13) cases. Six cases received expectant treatment (2 cases had termination of pregnancy due to progressing effusion, 2 cases had term delivery, and 2 cases had intrauterine death); the perinatal survival rate was 2/6. Six cases received TC (2 cases had term delivery, 2 cases had preterm delivery, and 2 cases had termination of pregnancy due to progressing effusion), the perinatal survival rate was 4/6. One case received TC+TAS (term delivery), the perinatal survival rate was 1/1. The overall perinatal survival rate of prenatal intrauterine intervention was 5/7. Conclusions: The clinical process of PFHT is changeable, and the pleural effusion will progress with gestational age. Intrauterine interventions could improve the perinatal survival rate.

Little empirical data are available on the extent to which capacity-building programs in research ethics prepare trainees to apply ethical reasoning skills to the design, conduct, or review of research. A randomized controlled trial was conducted in Botswana in 2010 to assess the effectiveness of a case-based intervention using email to augment in-person seminars. University faculty and current and prospective IRB/REC members took part in a semester-long training program in research ethics. Participants attended two 2-day seminars and were assigned at random to one of two on-line arms of the trial. Participants in both arms completed on-line international modules from the Collaborative Institutional Training Initiative. Between seminars, intervention-arm participants were also emailed a weekly case to analyze in response to set questions; responses and individualized faculty feedback were exchanged via email. Tests assessing ethics knowledge were administered at the start of each seminar. The post-test included an additional section in which participants were asked to identify the ethical issues highlighted in five case studies from a list of multiple-choice responses. Results were analyzed using regression and ANOVA. Of the 71 participants (36 control, 35 intervention) enrolled at the first seminar, 41 (57.7%) attended the second seminar (19 control, 22 intervention). In the intervention arm, 19 (54.3%) participants fully completed and 8 (22.9%) partially completed all six weekly cases. The mean score was higher on the post-test (30.3/40) than on the pre-test (28.0/40), and individual post- and pre-test scores were highly correlated (r = 0.65, p < 0.0001). Group assignment alone did not have an effect on test scores (p > 0.84), but intervention-arm subjects who completed all assigned cases answered an average of 3.2 more questions correctly on the post-test than others, controlling for pre-test scores (p = 0.003). Completion of the case-based intervention improved respondents' test scores, with those who completed all six email cases scoring roughly 10% better than those who failed to complete this task and those in the control arm. There was only suggestive evidence that intensive case work improved ethical issue identification, although there was limited ability to assess this outcome due to a high drop-out rate.

Interventions to improve communication among family members may facilitate information flow about familial risk and preventive health behaviors. This is a secondary analysis of the effects of an interactive website intervention aimed at increasing communication frequency and agreement about health risk among melanoma families. Participants were family units, consisting of one family member with melanoma identified from a previous research study (the case) and an additional first degree relative and a parent of a child 0–17. Family triads were randomized to receive access to the website intervention or to serve as control families. Family communication frequency and agreement about melanoma prevention behaviors and beliefs were measured at baseline and again at one year post randomization. Intervention participants of all three types significantly increased the frequency of communication to their first degree relatives (Parents, siblings, children; range =14–18 percentage points; all p<0.05). At baseline approximately two-thirds of all three family members talked with at least some member of the family about cancer risk. Agreement between Cases and First Degree Relatives and between Cases and Parents increased from pre to post intervention in the intervention participants compared to the control participants (p<0.05). These findings provide support for interventions to improve family communication about cancer risk. PMID:28248624

Detrimental effects of women's negative feelings during pregnancy have been extensively examined and documented, but research on the influence of positive feelings and protective factors on their prenatal mental health is scarce. Evidence from the positive psychology field has shown that practicing some brief positive exercises, called positive psychology interventions, can maximize well-being by increasing positive emotions, engagement, and meaning. The aim of this study is to examine the effect of a positive psychology web-based intervention on indices of women's prenatal well-being. Specifically, a case series design was adopted, and data from six women are presented. Participants were involved in a 5-week online positive psychology intervention that includes a set of positive psychology interventions specifically adapted for pregnant women. Measures of women's mental well-being, depression, pregnancy-related anxiety, life satisfaction, and social support were measured at pre- and post-intervention. Compliance with the intervention and exercise preferences were assessed at post-test. Single-item related well-being measures were assessed weekly. The findings of this case series study indicate potential effects of the intervention on supporting mental well-being and decreasing depressive symptomatology in these pregnant women. Furthermore, this study provides some suggestions for developing future online-based positive interventions addressed to pregnant women. However, these findings are preliminary, and future studies are needed in order to assess the effects of the intervention in a wider population of pregnant women.

Background Chronic heart failure (CHF) is a serious, common condition associated with frequent hospitalisation. Several different disease management interventions (clinical service organisation interventions) for patients with CHF have been proposed. Objectives To assess the effectiveness of disease management interventions for patients with CHF. Search methods We searched: Cochrane CENTRAL Register of Controlled Trials (to June 2003); MEDLINE (January 1966 to July 2003); EMBASE (January 1980 to July 2003); CINAHL (January 1982 to July 2003); AMED (January 1985 to July 2003); Science Citation Index Expanded (searched January 1981 to March 2001); SIGLE (January 1980 to July 2003); DARE (July 2003); National Research Register (July 2003); NHS Economic Evaluations Database (March 2001); reference lists of articles and asked experts in the field. Selection criteria Randomised controlled trials comparing disease management interventions specifically directed at patients with CHF to usual care. Data collection and analysis At least two reviewers independently extracted data information and assessed study quality. Study authors were contacted for further information where necessary. Main results Sixteen trials involving 1,627 people were included. We classified the interventions into three models: multidisciplinary interventions (a holistic approach bridging the gap between hospital admission and discharge home delivered by a team); case management interventions (intense monitoring of patients following discharge often involving telephone follow up and home visits); and clinic interventions (follow up in a CHF clinic). There was considerable overlap within these categories, however the components, intensity and duration of the interventions varied. Case management interventions tended to be associated with reduced all cause mortality but these findings were not statistically significant (odds ratio 0.86, 95% confidence interval 0.67 to 1.10, P = 0.23), although the evidence was stronger when analysis was limited to the better quality studies (odds ratio 0.68, 95% confidence interval 0.46 to 0.98, P = 0.04). There was weak evidence that case management interventions may be associated with a reduction in admissions for heart failure. It is unclear what the effective components of the case management interventions are. The single RCT of a multidisciplinary intervention showed reduced heart-failure related re-admissions in the short term. At present there is little available evidence to support clinic based interventions. Authors’ conclusions The data from this review are insufficient for forming recommendations. Further research should include adequately powered, multicentre studies. Future studies should also investigate the effect of interventions on patients’ and carers’ quality of life, their satisfaction with the interventions and cost effectiveness. PMID:15846638

Many studies have suggested the effectiveness of single control measures in the containment and mitigation of pandemic influenza A (H1N1) 2009. The effects of combined interventions by multiple control measures in reducing the impact of an influenza A (H1N1) 2009 outbreak in a closed physical training camp in Beijing, China were evaluated. Oseltamivir was prescribed for the treatment of confirmed cases and possible cases and as prophylaxis for all other participants in this training camp. Public health control measures were applied simultaneously, including the isolation of patients and possible cases, personal protection and hygiene, and social distancing measures. Symptom surveillance of all participants was initiated, and the actual attack rate was calculated. For comparison, the theoretical attack rate for this outbreak was projected using the Newton-Raphson numerical method. A total of 3256 persons were present at the physical training camp. During the outbreak, 405 (68.3%) possible cases and 26 (4.4%) confirmed cases were reported before the intervention and completed oseltamivir treatment; 162 (27.3%) possible cases were reported after the intervention and received part treatment and part prophylaxis. The other 2663 participants completed oseltamivir prophylaxis. Of the possible cases, 181 with fever ≥38.5°C were isolated. The actual attack rate for this outbreak of pandemic influenza A (H1N1) 2009 was 18.2%, which is much lower than the theoretical attack rate of 80% projected. Combined interventions of large-scale antiviral ring prophylaxis and treatment and public health control measures could be applied to reduce the magnitude of influenza A (H1N1) 2009 outbreaks in closed settings.

Lai, Hon-Sun; Chan, Chetwyn C H

2007-12-01

This paper reports the results of implementing a pilot case management system for work injuries in Hong Kong. The case management approach was characterized by use of a case manager who worked closely with each of the reported injury cases. The case manager undertook the roles of assessor, referral agent, counselor, work-site liaison, and return-to-work (RTW) expert. A quasi-experimental study design was used. The study compared the RTW and workers' compensation outcomes in injured workers in a cleaning company in a case management group (n = 296) and a conventional rehabilitation group (n = 137). Outcomes of the intervention were followed up at 6 months. The results indicated that the RTW rate was 97.0% and 94.2% for the case management and conventional rehabilitation groups respectively, with no significant differences between them. Participants in the case management group had significantly fewer days of sick leave (mean = 27.5 and 41.6 days, respectively) and lower compensation costs (mean = HK$7,212.2 and $20,617.3, respectively) than those in the comparison group. Age of the participants was found to influence the outcomes with those who were between 41 and 50 years old and received case management intervention had shorter sick leave and lower cost of compensation than their conventional rehabilitation counterpart. The majority of the participants who had returned to work in both the case management (95.8%) and the conventional rehabilitation (96.2%) groups were found to maintain their work status 6 months after the intervention. The findings suggested that applying the case management approach to the Hong Kong workers' compensation system was more effective overall. Nevertheless, the inherent problems associated with implementing such an approach within the existing system, which focuses on compensation and medical interventions, remained unresolved.

Single-case experimental designs are useful methods in clinical research practice to investigate individual client progress. Their proliferation might have been hampered by methodological challenges such as the difficulty applying existing statistical procedures. In this article, we describe a data-analytic method to analyze univariate (i.e., one symptom) single-case data using the common package SPSS. This method can help the clinical researcher to investigate whether an intervention works as compared with a baseline period or another intervention type, and to determine whether symptom improvement is clinically significant. First, we describe the statistical method in a conceptual way and show how it can be implemented in SPSS. Simulation studies were performed to determine the number of observation points required per intervention phase. Second, to illustrate this method and its implications, we present a case study of an adolescent with anxiety disorders treated with cognitive-behavioral therapy techniques in an outpatient psychotherapy clinic, whose symptoms were regularly assessed before each session. We provide a description of the data analyses and results of this case study. Finally, we discuss the advantages and shortcomings of the proposed method. Copyright © 2014. Published by Elsevier Ltd.

Settings: Swaziland is striving to achieve sustainable malaria elimination. Three preventive interventions are vital for reaching this goal: 1) effective household utilisation of long-lasting insecticide nets (LLINs), 2) indoor residual spraying (IRS), and 3) provision of chemoprophylaxis for those travelling to malaria-endemic areas. Objectives: To assess the uptake of preventive intervention among confirmed malaria cases. Design: A longitudinal study using nation-wide programme data from 2010 to 2015. Data on malaria cases from health facilities were sourced from the Malaria Surveillance Database System. Results: Of a total 2568 confirmed malaria cases in Swaziland, 2034 (79%) had complete data on case investigations and were included in the analysis. Of 341 (17%) individuals who owned LLINs, 169 (8%) used them; 338 (17%) had IRS and 314 (15%) slept in sprayed structures. Of 1403 travellers to areas at high malaria risk, 59 (4%) used any form of malaria prevention, including chemoprophylaxis. Conclusion: The uptake of all three key malaria prevention interventions is low, and could threaten the progress made thus far toward malaria elimination. Efforts to improve this situation, including qualitative research to understand the reasons for low uptake, are urgently needed. PMID:29713591

Effects of augmentative and alternative communication on challenging behavior: a meta-analysis.

Walker, Virginia L; Snell, Martha E

2013-06-01

The purposes of this review were to (a) use meta-analytic procedures to examine the effectiveness of single-case AAC intervention research on challenging behaviors exhibited by individuals with disabilities, (b) identify study characteristics that moderate intervention effects, and (c) evaluate the quality of research. The authors provided inferential and descriptive analyses of 54 studies representing 111 participants and estimated effect sizes using the Nonoverlap of All Pairs (NAP) method. Overall, AAC interventions were found to be equally effective across a broad spectrum of participants and interventions. AAC interventions were more effective with younger children than with adults. Interventions in which functional behavior assessments (FBA) were used had significantly larger effect sizes than those that did not use FBAs. Further, functional communication training interventions resulted in larger effect sizes than Picture Exchange Communication System interventions. Descriptive analysis revealed that (a) interventions often occurred in atypical environments (e.g., therapy room, experimental room) and with atypical interventionists (e.g., therapists, researchers), and (b) numerous studies did not exhibit quality characteristics of single-case research.

The community's awareness of Tuberculosis (TB) and delays in health care seeking remain important issues in Indonesia despite the extensive efforts of community-based TB programs delivered by a non-government organisation (NGO). This study explored the knowledge and behaviours in relation to TB and early diagnosis before and after an asset-based intervention designed to improve these issues. Six villages in Flores, Indonesia were purposively selected to participate in this study. Three villages served as intervention villages and the other three villages provided a comparison group. Data collection included interviews, group discussions, observations, field notes and audit of records. In total, 50 participants across six villages were interviewed and three group discussions were conducted in the intervention villages supplemented by 1 - 5 h of observation during monthly visits. Overall, participants in all villages had limited knowledge regarding the cause and transmission of TB before the intervention. The delay in health seeking behaviour was mainly influenced by ignorance of TB symptoms. Health care providers also contributed to delayed diagnosis by ignoring the symptoms of TB suspects at the first visit and failing to examine TB suspects with sputum tests. Stigmatisation of TB patients by the community was reported, although this did not seem to be common. Early case detection was less than 50 % in four of the six villages before the asset-based intervention. Knowledge of TB improved after the intervention in the intervention villages alongside improved education activities. Early case detection also increased in the intervention villages following this intervention. The behaviour changes related to prevention of TB were also obvious in the intervention villages but not the comparison group. This small project demonstrated that an asset-based intervention can result in positive changes in community's knowledge and behaviour in relation to TB and early case detection. A continuing education process is like to be required to maintain this outcome and to reach a wider community. Promoting community involvement and local initiatives and engaging health care providers were important elements in the community-based TB program implemented.

Investigate the effectiveness of health education programs by using the PRECEDE-PROCEED Model to improve non-Thai migrant TB patient's compliance during treatment. This quasi-intervention study was conducted in three targeted hospitals, between August 2009 and December 2010. The study sample consisted of 100 cases, 50 cases who registered in Samutsakorn Province served as the intervention group and 50 cases who registered in Samutprakarn Province served as the control group. At the end of the health education intervention, the intervention group showedsignificantly improved health-behavior scores in nine domains-health promotion, health education, predisposing, reinforcing, enabling factors, behavior and lifestyle, environment, and health status, which were also significantly higher than the control group (p < 0.001). The percentage of patients achieving successful treatment outcomes was 76% in the intervention group and 62% in the control group. The tuberculosis treatment and care program, and the associated health education interventions enabled migrants to complete the treatment regimen and achieve treatment success. It could also help TB staff develop an appropriate program and clear understanding of TB control among migrants. It is recommended that this type of information and health education program be used in other hospitals and healthcare settings providing TB services for migrants throughout the nation.

Current Canadian evidence illustrating the health benefits and cost-effectiveness of caregiver-friendly workplace policies is needed if Canadian employers are to adopt and integrate caregiver-friendly workplace policies into their employment practices. The goal of this three-year, three study research project is to provide such evidence for the auto manufacturing and educational services sectors. The research questions being addressed are: What are the impacts for employers (economic) and workers (health) of caregiver-friendly workplace policy intervention(s) for full-time caregiver-employees? What are the impacts for employers, workers and society of the caregiver-friendly workplace policy intervention(s) in each participating workplace? What contextual factors impact the successful implementation of caregiver-friendly workplace policy intervention(s)? Using a pre-post-test comparative case study design, Study A will determine the effectiveness of newly implemented caregiver-friendly workplace policy intervention(s) across two workplaces to determine impacts on caregiver-employee health. A quasi-experimental pre-post design will allow the caregiver-friendly workplace policy intervention(s) to be tested with respect to potential impacts on health, and specifically on caregiver employee mental, psychosocial, and physical health. Framed within a comparative case study design, Study B will utilize cost-benefit and cost-effectiveness analysis approaches to evaluate the economic impacts of the caregiver-friendly workplace policy intervention(s) for each of the two participating workplaces. Framed within a comparative case study design, Study C will undertake an implementation analysis of the caregiver-friendly workplace policy intervention(s) in each participating workplace in order to determine: the degree of support for the intervention(s) (reflected in the workplace culture); how sex and gender are implicated; co-workers' responses to the chosen intervention(s), and; other nuances at play. It is hypothesized that the benefits of the caregiver-friendly workplace policy intervention(s) will include improvements in caregiver-employees' mental, psychosocial and physical health, as well as evidence of cost-benefit and cost-effectiveness for the employer. The expected project results will provide the research evidence for extensive knowledge translation work, to be carried out in collaboration with our knowledge transition partners, to the employer/human resources and occupational health/safety target populations.

2017-01-01

Meaningfully synthesizing single case experimental data from intervention studies comprised of individuals with low incidence conditions and generating effect size estimates remains challenging. Seven effect size metrics were compared for single case design (SCD) data focused on teaching speech generating device use to individuals with intellectual and developmental disabilities (IDD) with moderate to profound levels of impairment. The effect size metrics included percent of data points exceeding the median (PEM), percent of nonoverlapping data (PND), improvement rate difference (IRD), percent of all nonoverlapping data (PAND), Phi, nonoverlap of all pairs (NAP), and Taunovlap. Results showed that among the seven effect size metrics, PAND, Phi, IRD, and PND were more effective in quantifying intervention effects for the data sample (N = 285 phase or condition contrasts). Results are discussed with respect to issues concerning extracting and calculating effect sizes, visual analysis, and SCD intervention research in IDD. PMID:27119210

To evaluate the impact of serial interventions on the incidence of methicillin-resistant Staphylococcus aureus (MRSA). Longitudinal observational study before and after interventions. The Alfred Hospital is a 350-bed tertiary referral hospital with a 35-bed intensive care unit (ICU). A series of interventions including the introduction of an antimicrobial hand-hygiene gel to the intensive care unit and a hospitalwide MRSA surveillance feedback program that used statistical process control charts but not active surveillance cultures. Serial interventions were introduced between January 2003 and May 2006. The incidence and rates of new patients colonized or infected with MRSA and episodes of MRSA bacteremia in the intensive care unit and hospitalwide were compared between the preintervention and intervention periods. Segmented regression analysis was used to calculate the percentage reduction in new patients with MRSA and in episodes of MRSA bacteremia hospitalwide in the intervention period. The rate of new patients with MRSA in the ICU was 6.7 cases per 100 patient admissions in the intervention period, compared with 9.3 cases per 100 patient admissions in the preintervention period (P=.047). The hospitalwide rate of new patients with MRSA was 1.7 cases per 100 patient admissions in the intervention period, compared with 3.0 cases per 100 patient admissions in the preintervention period (P<.001). By use of segmented regression analysis, the maximum and conservative estimates for percentage reduction in the rate of new patients with MRSA were 79.5% and 42.0%, respectively, and the maximum and conservative estimates for percentage reduction in the rate of episodes of MRSA bacteremia were 87.4% and 39.0%, respectively. A sustained reduction in the number of new patients with MRSA colonization or infection has been demonstrated using minimal resources and a limited number of interventions.

Frailty causes disability and restrictions on older people's ability to engage in leisure activities and for social participation. The objective of this study was to evaluate the effects of a 1-year case management intervention for frail older people living at home in Sweden in terms of social participation and leisure activities. The study was a randomised controlled trial with repeated follow-ups. The sample (n = 153) was consecutively and randomly assigned to intervention (n = 80) or control groups (n = 73). The intervention group received monthly home visits over the course of a year by nurses and physiotherapists working as case managers, using a multifactorial preventive approach. Data collections on social participation, leisure activities and rating of important leisure activities were performed at baseline, 3, 6, 9 and 12 months, with recruitment between October 2006 and April 2011. The results did not show any differences in favour of the intervention on social participation. However, the intervention group performed leisure activities in general, and important physical leisure activities, to a greater extent than the control group at the 3-month follow-up (median 13 vs. 11, P = 0.034 and median 3 vs. 3, P = 0.031 respectively). A statistically significantly greater proportion of participants from the intervention group had an increased or unchanged number of important social leisure activities that they performed for the periods from baseline to 3 months (93.2% vs. 75.4%, OR = 4.48, 95% CI: 1.37-14.58). Even though statistically significant findings in favour of the intervention were found, more research on activity-focused case management interventions is needed to achieve clear effects on social participation and leisure activities. © 2017 John Wiley & Sons Ltd.

Should structural interventions be evaluated using RCTs? The case of HIV prevention.

Bonell, Christopher; Hargreaves, James; Strange, Vicki; Pronyk, Paul; Porter, John

2006-09-01

Structural interventions addressing macro-social determinants of risk have been suggested as potentially important adjuncts to biomedical and behavioural interventions for the prevention of HIV and other diseases. A few interventions of this type have been evaluated using randomised controlled trials (RCTs), the most rigorous design to evaluate the effects of biomedical and behavioural interventions. The appropriateness of applying RCTs to structural interventions is however debated. This paper considers whether issues of ethics, feasibility and utility preclude the use of RCTs in evaluations of structural interventions for HIV prevention. We conclude there is nothing particular to this category of interventions prohibiting use of RCTs. However, we suggest that RCTs may prove unacceptable, unfeasible or not useful in certain circumstances, such as where an intervention brings important benefits other than HIV prevention (such as increased income); where leaders of clusters do not allow decisions about macro-social policies to be determined randomly; where the unit of social organization addressed by an intervention is so large that recruitment of adequate numbers of clusters is impossible; and where the period required to trial interventions extends beyond practical decision-making time-scales. In such cases, alternative evaluative designs must be assessed for their ability to provide evidence of intervention effectiveness.

We sought to determine the relationship between relative value units (RVUs) and intended measures of work in catheterization for congenital heart disease. RVU was determined by matching RVU values to Current Procedural Terminology codes generated for cases performed at a single institution. Differences in median case duration, radiation exposure, adverse events, and RVU values by risk category and cases were assessed. Interventional case types were ranked from lowest to highest median RVU value, and correlations with case duration, radiation dose, and a cases-predicted probability of an adverse event were quantified with the Spearman rank correlation coefficient. Between January 2008 and December 2010, 3557 of 4011 cases were identified with an RVU and risk category designation, of which 2982 were assigned a case type. Median RVU values, radiation dose, and case duration increased with procedure risk category. Although all diagnostic cases had similar RVU values (median 10), adverse event rates ranged from 6% to 21% by age group (P < .001). Median RVU values ranged from 9 to 54 with the lowest in diagnostic and biopsy cases and increasing with isolated and then multiple interventions. Among interventional cases, no correlation existed between ranked RVU value and case duration, radiation dose, or adverse event probability (P = .13, P = .62, and P = .43, respectively). Time, skill, and stress inherent to performing catheterization procedures for congenital heart disease are not captured by measurement of RVU alone.

Setting Multidrug-resistant tuberculosis (MDR-TB) unit in KwaZulu-Natal, South Africa. Objective To develop and evaluate a nurse case management model and intervention using the tenets of the Chronic Care Model to manage treatment for MDR-TB patients with a high prevalence of human immunodeficiency virus (HIV) co-infection. Design A quasi-experimental pilot programme utilizing a nurse case manager to manage care for 40 hospitalized MDR-TB patients, 70% HIV co-infected, during the intensive phase of MDR-TB treatment. Patients were followed for six months to compare proximal outcomes identified in the model between the pre- and post-intervention period. Results The greatest percent differences between baseline and six-month MDR-TB proximal outcomes were seen in the following three areas: baseline symptom evaluation on treatment initiation (95% improvement), baseline and monthly laboratory evaluations completed per guidelines (75% improvement), and adverse drug reactions acted upon by medical and/or nursing intervention (75% improvement). Conclusion Improvements were identified in guideline-based treatment and monitoring of adverse drug reactions following implementation of the nurse case management intervention. Further study is required to determine if the intervention introduced in this model will ultimately result in improvements in final MDR-TB treatment outcomes. PMID:25405988

Enhancing situational interest in pediatrics.

Individual interest, something that persists regardless of the situation, and situational interest, finding personal value in an educational context, have not been studied in medical student education. To determine if individualized case discussions enhance interest in pediatric medicine. During the 2008/2009 academic year, 88 clerkship students participated in clinical case discussions. At orientation, students completed an Interest in Pediatrics (IIP) questionnaire, responding 1 = strongly disagree to 5 = strongly agree. Intervention and control groups were randomly assigned. The intervention group personalized cases to students' medical specialty interests. The control group discussed the case presentation. Groups met twice during the 8-week clerkships, completing a post-IIP at the end of the clerkship. Intervention group interest increased from pre-IIP, mean = 3.64, to post-IIP, mean = 4.22 (z = -2.994, p < 0.05, r = -0.44). On post-IIP, application of pediatric medicine increased for both groups; the intervention group was most significant from pre-IIP, mean = 1.09, to post-IIP, mean = 4.33 (z = -6.038, p < 0.05, r = -0.88). Enhanced interest in pediatrics from the intervention group indicates that creating a learning environment personally relevant to students' careers facilitates interest to learn.

Despite a large number of evidence-based health communication interventions tested in private, public, and community health settings, there is a dearth of research on successful secondary dissemination of these interventions to other audiences. This article presents the case study of “1-2-3 Pap,” a health communication intervention to improve human papillomavirus (HPV) vaccination uptake and Pap testing outcomes in Eastern Kentucky, and explores strategies used to disseminate this intervention to other populations in Kentucky, North Carolina, and West Virginia. Through this dissemination project, we identified several health communication intervention design considerations that facilitated our successful dissemination to these other audiences; these intervention design considerations include (a) developing strategies for reaching other potential audiences, (b) identifying intervention message adaptations that might be needed, and (c) determining the most appropriate means or channels by which to reach these potential future audiences. Using “1-2-3 Pap” as an illustrative case study, we describe how careful planning and partnership development early in the intervention development process can improve the potential success of enhancing the reach and effectiveness of an intervention to other audiences beyond the audience for whom the intervention messages were originally designed.

New arrows in the quiver for targeting care management: high-risk versus high-opportunity case identification.

PubMed

Bernstein, Richard H

2007-01-01

"Care management" purposefully obscures the distinctions between disease and case management and stresses their common features: action in the present to prevent adverse future outcomes and costs. It includes identifying a high-need population by referrals, screening, or data analysis, assessing those likely to benefit from interventions, intervening, evaluating the intervention, and adjusting interventions when needed. High-risk individuals can be identified using at least 9 techniques, from referrals and questionnaires to retrospective claims analysis and predictive models. Other than referrals, software based on the risk-adjustment methodology that we have adapted can incorporate all these methodologies. Because the risk adjustment employs extensive case mix and severity adjustment, it provides care managers with 3 innovative ways to identify not only high-risk individuals but also high-opportunity cases.

2017-04-01

The objective of this study was to assess whether an intervention on process efficiency using the Lean methodology leads to improved utilization of the operating room (OR), as measured by key performance metrics of OR efficiency. A quasi-experimental design was used to test the impact of the intervention by comparing pre-intervention and post-intervention data on five key performance indicators. The ORs of 12 hospitals were selected across regions of the Kingdom of Saudi Arabia (KSA). The participants were patients treated at these hospitals during the study period. The intervention comprised the following: (i) creation of visual dashboards that enable starting the first case on time; (ii) use of computerized surgical list management; (iii) optimization of time allocation; (iv) development of an operating model with policies and procedures for the pre-anesthesia clinic; and (iv) creation of a governance structure with policies and procedures for day surgeries. The following were the main outcome measures: on-time start for the first case, room turnover times, percent of overrun cases, average weekly procedure volume and OR utilization. The hospital exhibited statistically significant improvements in the following performance metrics: on-time start for the first case, room turnover times and percent of overrun cases. A statistically significant difference in OR utilization or average weekly procedure volumes was not detected. The implementation of a Lean-based intervention targeting process efficiency applied in ORs across various KSA hospitals resulted in encouraging results on some metrics at some sites, suggesting that the approach has the potential to produce significant benefit in the future.

Background: The self-efficacy of thalassemia patients is an important factor in creating behavioral changes in such patients. Home-care training reduces hospitalization duration as well as relevant costs and improves disease outcomes. This study was designed to assess the effect of home-care training on the self-efficacy of patients with beta thalassemia major. Methodology: This was a quasi-experimental, case-control, before and after intervention study conducted on 136 thalassemia cases from January 2014 to October 2015. Data was collected through Shere general self-efficacy questionnaire (SGSES). Home-care trainings were provided in the form of training courses with respect to the training needs of thalassemia major cases. Two (2) months after the end of training courses, SGSES questionnaire was filled again and the obtained data was analyzed by SPSS 21 as well as descriptive-inferential statistics (significance level=P≤0.05). Results: The results of this study revealed that the mean self-efficacy score of control group was 48.69±6.82 before intervention which increased to 46.69±6.81 after intervention. The mean self-efficacy score of case group was 44.58±5.23 before intervention which increased to 49.5±6.66 after intervention. The rise of self-efficacy score, after intervention, was significantly higher in the case group compared with the control group (P≤.001). Conclusion: According to results, home-care training can develop self-efficacy in thalassemia patients. In home-care training procedure patients play an active role. By providing home-care trainings, therefore, an effective step should be taken to promote the self-efficacy of the patients and to decrease associated problems. PMID:27999484

Background: Opioids have narrow therapeutic windows, and errors in ordering or administration can be fatal. The purpose of this study was to describe deaths involving hydromorphone and morphine, which have similar-sounding names, but different potencies. Methods: In this case series, we describe deaths of patients admitted to hospital or residents of long-term care facilities that involved hydromorphone and morphine. We searched for deaths referred to the Patient Safety Review Committee of the Office of the Chief Coroner for Ontario between 2007 and 2012, and subsequently reviewed by 2014. We reviewed each case to identify intervention points where errors could have been prevented. Results: We identified 8 cases involving decedents aged 19 to 91 years. The cases involved errors in prescribing, order processing and transcription, dispensing, administration and monitoring. For 7 of the 8 cases, there were multiple (2 or more) possible intervention points. Six cases may have been prevented by additional patient monitoring, and 5 cases involved dispensing errors. Interpretation: Opioid toxicity deaths in patients living in institutions can be prevented at multiple points in the prescribing and dispensing processes. Interventions aimed at preventing errors in hydromorphone and morphine prescribing, administration and patient monitoring should be implemented and rigorously evaluated. PMID:28401133

Woodhouse, Susan S

2018-05-21

Given a large body of research indicating links between child attachment and later mental health outcomes, interventions that promote children's secure attachment to their caregivers have the potential to contribute to prevention of psychopathology and promotion of well-being. A number of attachment-based interventions have been developed to support parents, enhance caregiving quality, and promote children's attachment security with the aim of improving children's mental health. There is now a growing evidence base to support the efficacy of a number of these interventions. The present literature review and introduction to the special issue on attachment-based interventions for families with young children describes key aspects of attachment theory and research that form the theoretical and empirical background for attachment-based interventions, and introduces seven case studies illustrating five different attachment-based interventions. The case studies represent a variety of attachment-based models, including both group and individual treatments, and show applications across a range of caregiver contexts. © 2018 Wiley Periodicals, Inc.

A case series of interventional radiology in postpartum haemorrhage.

Agarwal, N; Deinde, O; Willmott, F; Bojahr, H; MacCallum, P; Renfrew, I; Beski, S

2011-08-01

Postpartum haemorrhage (PPH) remains a significant cause of maternal morbidity and mortality in both developed and developing countries. In some instances, PPH can be anticipated and recent improvements in obstetric imaging techniques allow earlier and more reliable diagnosis of abnormalities associated with haemorrhage such as morbid placentation. However, the majority of PPH is unpredicted. Good practice notes published by the Royal College of Obstetricians and Gynaecologists state interventional radiology should be used as emergency intervention in PPH and should be considered when primary management has failed allowing arteries to be embolised to achieve haemostasis. Through collaboration between interventional radiology and maternity, appropriate guidelines need to be developed, on both emergency and elective of interventional radiology in the prevention and management of PPH. As there is mapping for neonatal services, in the future there should be consideration to develop obstetric trauma units. Maternity units which lack facilities for interventional radiology would be able to refer their cases (like placenta accreta) for safe management in units with 24 h interventional radiology services.

Importation of infectious tuberculosis (TB) threatens TB control in California and the United States. To assess the effectiveness of an enhanced pre-immigration screening and treatment protocol to prevent the importation of infectious TB. Retrospective analysis of immigrants ≥ 15 years of age with TB suspect classifications who were screened for TB in their countries of origin before (pre-intervention cohort) and after (post-intervention cohort) implementation of enhanced pre-immigration screening. Enhanced pre-immigration screening added sputum cultures to the existing screening system based on sputum smears for persons with abnormal chest radiographs. The pre- and post-intervention cohorts included respectively 2049 and 1430 immigrants. The occurrence of tuberculosis ≤ 6 months after US arrival in this population decreased following the intervention, from 4.2% (86 cases) to 1.5% (22 cases, P < 0.001). Among pre-intervention cohort cases, 14% were sputum acid-fast bacilli (AFB) smear-positive and 81% were sputum culture-positive for TB, compared with 5% sputum AFB smear-positive (P = 0.46) and 68% sputum culture-positive (P = 0.18) among the post-intervention cohort cases. The enhanced pre-immigration screening was associated with a decline in the proportion of immigrants with TB suspect classifications identified with TB within 6 months of arrival in the United States. Continued state and national surveillance is critical to monitor the effectiveness of the revised pre-immigration screening as it is implemented in additional countries.

PurposeTransradial access (TRA) has shown lower morbidity and decreased bleeding complications compared to transfemoral access. This study evaluates the safety and feasibility of TRA in thrombocytopenic patients undergoing visceral interventions.Methods and MaterialsPatients who underwent visceral interventions via the radial artery with platelet count less than or equal to 50,000/µL were included in the study. Outcome variables included technical success, access site, bleeding, transfusion, and neurological complications.ResultsFrom July 1, 2012, to May 31, 2015, a total of 1353 peripheral interventions via TRA were performed, of which 85 procedures were performed in 64 patients (mean age 62.2 years) with a platelet count <50,000/µLmore » (median 39,000/µL). Interventions included chemoembolization (n = 46), selective internal radiation therapy (n = 30), and visceral embolization (n = 9). Technical success was 97.6 % with two cases of severe vessel spasm requiring ipsilateral femoral crossover. There was no major access site, bleeding, or neurological adverse events at 30 days. Minor access site hematomas occurred in five cases (5.9 %) and were treated conservatively in all cases. Pre-procedural platelet transfusions were administered in 23 (27.1 %) cases. There was no statistically significant difference in access site or bleeding complications between the transfused and nontransfused groups.ConclusionsTransradial visceral interventions in patients with thrombocytopenia are both feasible and safe, possibly without the need for platelet transfusions.« less

Background The aim of this study was to populate the Equitable Impact Sensitive Tool (EQUIST) framework with all necessary data and conduct the first implementation of EQUIST in studying cost–effectiveness of community case management of childhood pneumonia in 5 low– and middle–income countries with relation to equity impact. Methods Wealth quintile–specific data were gathered or modelled for all contributory determinants of the EQUIST framework, namely: under–five mortality rate, cost of intervention, intervention effectiveness, current coverage of intervention and relative disease distribution. These were then combined statistically to calculate the final outcome of the EQUIST model for community case management of childhood pneumonia: US$ per life saved, in several different approaches to scaling–up. Results The current ‘mainstream’ approach to scaling–up of interventions is never the most cost–effective. Community–case management appears to strongly support an ‘equity–promoting’ approach to scaling–up, displaying the highest levels of cost–effectiveness in interventions targeted at the poorest quintile of each study country, although absolute cost differences vary by context. Conclusions The relationship between cost–effectiveness and equity impact is complex, with many determinants to consider. One important way to increase intervention cost–effectiveness in poorer quintiles is to improve the efficiency and quality of delivery. More data are needed in all areas to increase the accuracy of EQUIST–based estimates. PMID:23289077

The aim of this study was to investigate the impact of an intensive 10-week course of articulation therapy on articulation errors in cleft lip and palate patients who have Velopharyngeal Insufficiency (VPI), non-oral and passive cleft speech characteristics. Five children with cleft palate (+/-cleft lip) with VPI and non-oral and passive cleft speech characteristics underwent 40 intensive articulation therapies over 10 weeks in a single case experimental design. The percentage of non-oral CSCs (NCSCs), passive CSCs (PCSCs), stimulable consonants (SC), correct consonants in word imitation (CCI), and correct consonants in picture naming (CCN) were captured at baseline, during intervention and in follow up phases. Visual analysis and two effect size indexes of Percentage of Nonoverlapping Data and Percentage of Improvement Rate Difference were analyzed. Articulation therapy resulted in visible decrease in NCSCs for all 5 participants across the intervention phases. Intervention was effective in changing percentage of passive CSCs in two different ways; it reduced the PCSCs in three cases and resulted in an increase in PCSCs in the other two cases. This was interpreted as intervention having changed the non-oral CSCs to consonants produced within the oral cavity but with passive characteristics affecting manner of production including weakness, nasalized plosives and nasal realizations of plosives and fricatives. Percent SC increased throughout the intervention period in all five patients. All participants demonstrated an increase in percentage of CCI and CCN suggesting an increase in the consonant inventory. Follow-up data showed that all the subjects were able to maintain their ability to articulate learned phonemes correctly even after a 4-week break from intervention. This single case experimental study supports the hypothesis that speech intervention in patients with VPI can result in an improvement in oral placements and passive CSCs.

During 2006, Israeli hospitals faced a clonal outbreak of carbapenem-resistant Klebsiella pneumoniae that was not controlled by local measures. A nationwide intervention was launched to contain the outbreak and to introduce a strategy to control future dissemination of antibiotic-resistant bacteria in hospitals. In March 2007, the Ministry of Health issued guidelines mandating physical separation of hospitalized carriers of carbapenem-resistant Enterobacteriaceae (CRE) and dedicated staffing and appointed a professional task force charged with containment. The task force paid site visits at acute-care hospitals, evaluated infection-control policies and laboratory methods, supervised adherence to the guidelines via daily census reports on carriers and their conditions of isolation, provided daily feedback on performance to hospital directors, and intervened additionally when necessary. The initial intervention period was 1 April 2007-31 May 2008. The primary outcome measure was incidence of clinically diagnosed nosocomial CRE cases. By 31 March 2007, 1275 patients were affected in 27 hospitals (175 cases per 1 million population). Prior to the intervention, the monthly incidence of nosocomial CRE was 55.5 cases per 100,000 patient-days. With the intervention, the continuous increase in the incidence of CRE acquisition was halted, and by May 2008, the number of new monthly cases was reduced to 11.7 cases per 100,000 patient-days (P<.001). There was a direct correlation between compliance with isolation guidelines and success in containment of transmission (P=.02). Compliance neutralized the effect of carrier prevalence on new incidence (P=.03). A centrally coordinated intervention succeeded in containing a nationwide CRE outbreak after local measures failed. The intervention demonstrates the importance of strategic planning and national oversight in combating antimicrobial resistance. © The Author 2011.

Several studies have highlighted the implications of impulsivity and novelty seeking for both the maintenance and the process of recovery from bulimia nervosa (BN). Cognitive behavioral therapy (CBT) is the treatment of choice for BN, but for some cases, this treatment alone might not be sufficient for reducing the high levels of impulsivity. The paper presents a case report of a patient with BN, examining the effectiveness of using a videogame (VG; Playmancer) as an additional intervention designed to address impulsivity. Psychometric and neuropsychological measures were collected at baseline. After this assessment, Playmancer was applied prior to CBT, following an "A-B-A-C-A" single case experimental design. Impulsivity levels were assessed with the Conner's Continuous Performance Test II (CPT-II). After the Playmancer treatment, the patient started CBT, and the levels of impulsivity were recorded again. Finally, psychometric and neuropsychological measures were collected after treatment. Weekly frequency of binges and vomiting were also recorded during the entire procedure. After the VG intervention, psychometric measures such as anxiety levels, impulsivity and novelty seeking decreased. Regarding the neuropsychological measures, impulsivity levels (measured with the CPT-II) progressively decreased throughout the intervention, and an improvement in decision making capacities was observed. Furthermore, the frequency of binges also decreased during and after the VG intervention. This case report suggests that using the Playmancer VG to reduce impulsivity prior to CBT may enhance the final results of the treatment for BN.

A systematic review was conducted to categorize and describe Intervention Models involving community health workers (CHWs) that aim to improve case management of sick children at the household and community levels. The review focused on management of children with signs of malaria or pneumonia. Seven Intervention Models were identified, and classified according to: (1) the role of CHWs and families in assessment and treatment of children, (2) system of referral to the nearest health facility (verbal or facilitated), and (3) the location in the community of the drug stock. Standardization of terminology for Intervention Models using this or a similar classification could facilitate comparison and selection of models, including deciding how to modify programmes when policies change concerning first-line drugs, and setting priorities for further research. Of the seven models, that of CHW pneumonia case management (Model 6) has the strongest evidence for an impact on mortality. Pneumonia case management by CHWs is a child health intervention that warrants considerably more attention, particularly in Africa and South Asia.

Background Interventions in occupational health often target worksites rather than individuals. The objective of this paper is to describe the (lack of) stability in units of analysis in occupational health and safety intervention projects directed toward worksites. Methods A case study approach is used to describe naturally occurring organizational changes in four, large, Nordic intervention projects that ran 3–5 years, covered 3–52 worksites, cost 0.25 mill–2.2 mill €, and involved 3–7 researchers. Results In all four cases, high rates of closing, merging, moving, downsizing or restructuring was observed, and in all four cases at least one company/worksite experienced two or more re-organizations during the project period. If individual worksites remained, ownership or (for publicly owned) administrative or legal base often shifted. Forthcoming closure led employees and managers to seek employment at other worksites participating in the studies. Key employees involved in the intervention process often changed. Conclusion Major changes were the rule rather than the exception. Frequent fundamental changes at worksites need to be taken into account when planning intervention studies and raises serious questions concerning design, analyses and interpretation of results. The frequent changes may also have deleterious implications for the potential effectiveness of many real life interventions directed toward worksites. We urge researchers and editors to prioritize this subject in order to improve the quality of future intervention research and preventive action. PMID:18554380

Integrated package approach in delivering interventions during immunisation campaigns in a complex environment in Papua New Guinea: a case study.

Papua New Guinea's difficult and varied topography, poor transport infrastructure, changing dynamics of population and economy in recent times and understaffed and poorly financed health service present major challenges for successful delivery of vaccination and other preventative health interventions to both the rural majority and urban populations, thereby posing risks for vaccine preventable disease outbreaks in the country. The country has struggled to meet the vaccination coverage targets required for the eradication of poliomyelitis and elimination of measles. Escalation of inter and intra country migration resulting from major industrial developments, particularly in extraction industries, has substantially increased the risk of infectious disease importation. This case study documents the evolution of immunisation programmes since the introduction of supplementary immunisation activities (SIAs). Single antigen SIAs have advantages and disadvantages. In situations in which the delivery of preventative health interventions is difficult, it is likely that the cost benefit is greater for multiple than for single intervention. The lessons learned from the conduct of single antigen SIAs can be effectively used for programmes delivering multiple SIA antigens, routine immunisations, and other health interventions. This paper describes a successful and cost effective multiple intervention programme in Papua New Guinea. The review of the last SIA in Papua New Guinea showed relatively high coverage of all the interventions and demonstrated the operational feasibility of delivering multiple interventions in resource constrained settings. Studies in other developing countries such as Lesotho and Ethiopia have also successfully integrated health interventions with SIA. In settings such as Papua New Guinea there is a strong case for integrating supplementary immunisation activity with routine immunisation and other health interventions through a comprehensive outreach programme.

The use of interventional radiology has increased as the first-line management of complications after pancreatic resections. Patients in whom interventional radiology was performed were compared with those in whom interventional radiology was not performed as regards type of pancreatic resection, diagnosis, postoperative mortality and morbidity, postoperative pancreatic fistula postpancreatectomy haemorrhage, bile leakage, reoperation rate and length of hospital stay. Our aim was to evaluate the usefulness of interventional radiology in the treatment of complications after pancreatic resection. One hundred and eighty-two (62.8%) out of 290 patients experienced postoperative complications. Interventional radiology procedures were performed in 37 cases (20.3%): percutaneous drainage in 28, transhepatic biliary drainage in 8 and arterial embolisation in 3 cases. Technical success was obtained in all cases and clinical success in 75.7%. Reoperation was avoided in 86.5%. In patients with major complications, clinically relevant postoperative pancreatic fistula and bile leaks as well as those with late postpancreatectomy haemorrhage (P=0.030) and patients with postpancreatectomy haemorrhage grade C (P=0.029), interventional radiology was used (P<0.001, P<0.001 and P=0.009, respectively) significantly more frequently than in the remaining patients. The reoperation and mortality rates were similar in the two groups (P=0.885 and P=0.100, respectively) while patients treated with interventional radiology procedures had a significant longer length of hospital stay than those in the non-interventional radiology group (37.5 ± 23.4 vs. 18.7 ± 11.7 days; P<0.001). Interventional radiology procedures were useful, especially for patients with postoperative pancreatic fistulas and bile leaks in whom reoperation was very often avoided.

Evaluating participatory decision processes: which methods inform reflective practice?

PubMed

Kaufman, Sanda; Ozawa, Connie P; Shmueli, Deborah F

2014-02-01

Evaluating participatory decision processes serves two key purposes: validating the usefulness of specific interventions for stakeholders, interveners and funders of conflict management processes, and improving practice. However, evaluation design remains challenging, partly because when attempting to serve both purposes we may end up serving neither well. In fact, the better we respond to one, the less we may satisfy the other. Evaluations tend to focus on endogenous factors (e.g., stakeholder selection, BATNAs, mutually beneficial tradeoffs, quality of the intervention, etc.), because we believe that the success of participatory decision processes hinges on them, and they also seem to lend themselves to caeteris paribus statistical comparisons across cases. We argue that context matters too and that contextual differences among specific cases are meaningful enough to undermine conclusions derived solely from comparisons of process-endogenous factors implicitly rooted in the caeteris paribus assumption. We illustrate this argument with an environmental mediation case. We compare data collected about it through surveys geared toward comparability across cases to information elicited through in-depth interviews geared toward case specifics. The surveys, designed by the U.S. Institute of Environmental Conflict Resolution, feed a database of environmental conflicts that can help make the (statistical) case for intervention in environmental conflict management. Our interviews elicit case details - including context - that enable interveners to link context specifics and intervention actions to outcomes. We argue that neither approach can "serve both masters." Copyright © 2013 Elsevier Ltd. All rights reserved.

Case-Control Study of Injury Intervention for Preschool Children in Henggang, Shenzhen.

Wang, Hong; Liu, Yi-Xin; Deng, Wen-Jiao; Yang, Wei-Jian; Wang, Fang

2015-10-01

To explore effective interventions for child accidental injury prevention and to reduce the incidence of injury. Cluster random sampling method was adopted, and children in 19 kindergartens in Henggang, Shenzhen and their parents were selected as the objects of study. Nineteen kindergartens were randomly divided into intervention group and control group to carry out the injury intervention case-control study. Through a series of interventions, there were certain effects. After the end of the project, the injury incidence rates of the intervention group and the control group were 4.91%, 10.64%, and the difference was significant; the average costs of treatment for injuries of the intervention group and the control group were 168.4 Yuan and 206.8 Yuan, and the difference was statistically significant; compared with before the implementation of the project, the rate of various types of injuries after the end of the project declined, in which, the rate of mechanical injury, pet bites, accidental falls, burns, and traffic accidents decreased significantly. The differences were significant. Injury interventions can effectively prevent and control the occurrence of injury.

An evaluation of the effectiveness of a case-specific approach to challenging behaviour associated with dementia.

PubMed

Bird, Michael; Llewellyn-Jones, Robert H; Korten, Ailsa

2009-01-01

Treatment of challenging behaviour in dementia using standardized psychopharmacological or psychosocial approaches remains problematical. A case-specific approach was trialled in this study, based on extensive evidence that each case is different in aetiology, the effects of the behaviour on others and what interventions are possible given the available resources. Forty-four consecutive referrals for challenging behaviour (two-thirds in residential care) were assessed across multiple causal domains. Both assessment and development of interventions were undertaken in collaboration with family carers and care staff. Measures of behaviour and associated carer distress, as well as medication and service use, were taken pre-intervention and at 2- and 5-month follow-ups. Psychotropic medication was used with a minority of participants but, overall, antipsychotic use was reduced. Psychosocial methods predominated, with 77% of cases judged as mainly or entirely psychosocial by an expert panel. There were significant mean improvements in behaviour and carer distress. Using conservative criteria there was a 65.9% clinical success rate. Results confirm those of other studies which have used multifaceted interventions tailored to the unique needs of each case. They compare favourably with results from trials of standardized psycho-pharmacological or psychosocial approaches. More trials are needed, necessarily involving further development of robust methodologies which reflect the case-specific nature of challenging behaviour associated with dementia.

Designing a complex intervention for dementia case management in primary care

PubMed Central

2013-01-01

Background Community-based support will become increasingly important for people with dementia, but currently services are fragmented and the quality of care is variable. Case management is a popular approach to care co-ordination, but evidence to date on its effectiveness in dementia has been equivocal. Case management interventions need to be designed to overcome obstacles to care co-ordination and maximise benefit. A successful case management methodology was adapted from the United States (US) version for use in English primary care, with a view to a definitive trial. Medical Research Council guidance on the development of complex interventions was implemented in the adaptation process, to capture the skill sets, person characteristics and learning needs of primary care based case managers. Methods Co-design of the case manager role in a single NHS provider organisation, with external peer review by professionals and carers, in an iterative technology development process. Results The generic skills and personal attributes were described for practice nurses taking up the case manager role in their workplaces, and for social workers seconded to general practice teams, together with a method of assessing their learning needs. A manual of information material for people with dementia and their family carers was also created using the US intervention as its source. Conclusions Co-design produces rich products that have face validity and map onto the complexities of dementia and of health and care services. The feasibility of the case manager role, as described and defined by this process, needs evaluation in ‘real life’ settings. PMID:23865537

2015-11-01

The objective of this study was to investigate the effectiveness of interventional catheterization with staphylococcin aureus injection on ischemic necrosis of the femoral heads. By percutaneous catheterization of the femoral artery, papaverine, urokinase, compound Danshen, and anisodamine were injected intravenously into the arteries of the femoral head. Staphylococcin aureus injection was injected into the hit joint capsule on the side of the lesion to compare the conditions before and after surgery. The patients did the rehabilitation exercises of the hit joint 48 h after the surgery and had double crutches for 3-6 months. Of the 112 cases, 39 cases (34.8 %) were cured, 51 cases (45.6 %) were markedly effective, and 22 cases (19.6 %) were effective. Interventional catheterization combined with staphylococcin aureus injection given into the hit joint capsule is an effective way to treat ischemic necrosis of the femoral head by influencing the internal and external environments of the femoral head.

In muscle lengthening surgery multiple aponeurotomy does not improve intended acute effects and may counter-indicate: an assessment by finite element modelling.

PubMed

Yucesoy, Can A; Seref-Ferlengez, Zeynep; Huijing, Peter A

2013-01-01

The goal was to assess the effects of multiple aponeurotomy on mechanics of muscle with extramuscular myofascial connections. Using finite element modelling, effects of combinations of the intervention carried out at a proximal (P), an intermediate (I) and a distal (D) location were studied: (1) Case P, (2) Case P-I, (3) Case P-D and (4) Case P-I-D. Compared to Case P, the effects of multiple interventions on muscle geometry and sarcomere lengths were sizable for the distal population of muscle fibres: e.g. at high muscle length (1) summed gap lengths between the cut ends of aponeurosis increased by 16, 25 and 27% for Cases P-I, P-D and P-I-D, respectively, (2) characteristic substantial sarcomere shortening became more pronounced (mean shortening was 26, 29, 30 and 31% for Cases P, P-I, P-D and P-I-D, respectively) and (3) fibre stresses decreased (mean stress equalled 0.49, 0.39, 0.38 and 0.33 for Cases P, P-I, P-D and P-I-D, respectively). In contrast, no appreciable effects were shown for the proximal population. The overall change in sarcomere length heterogeneity was limited. Consequently, the effects of multiple aponeurotomy on muscle length-force characteristics were marginal: (1) a limited reduction in active muscle force (maximal 'muscle weakening effect' remained between 5 and 11%) and (2) an even less pronounced change in slack to optimum length range of force exertion (maximal 'muscle lengthening effect' distally was 0.2% for Case P-I-D) were shown. The intended effects of the intervention were dominated by the one intervention carried out closer to the tendon suggesting that aponeurotomies done additionally to that may counter-indicated.

Pandemic controllability: a concept to guide a proportionate and flexible operational response to future influenza pandemics.

PubMed

McCaw, J M; Glass, K; Mercer, G N; McVernon, J

2014-03-01

The 2009 H1N1 influenza pandemic posed challenges for governments worldwide. Strategies designed to limit community transmission, such as antiviral deployment, were largely ineffective due to both feasibility constraints and the generally mild nature of disease, resulting in incomplete case ascertainment. Reviews of national pandemic plans have identified pandemic impact, primarily linked to measures of transmissibility and severity, as a key concept to incorporate into the next generation of plans. While an assessment of impact provides the rationale under which interventions may be warranted, it does not directly provide an assessment on whether particular interventions may be effective. Such considerations motivate our introduction of the concept of pandemic controllability. For case-targeted interventions, such as antiviral treatment and post-exposure prophylaxis, we identify the visibility and transmissibility of a pandemic as the key drivers of controllability. Taking a case-study approach, we suggest that high-impact pandemics, for which control is most desirable, are likely uncontrollable with case-targeted interventions. Strategies that do not rely on the identification of cases may prove relatively more effective. By introducing a pragmatic framework for relating the assessment of impact to the ability to mitigate an epidemic (controllability), we hope to address a present omission identified in pandemic response plans.

Intervention description is not enough: evidence from an in-depth multiple case study on the untold role and impact of context in randomised controlled trials of seven complex interventions

PubMed Central

2012-01-01

Background A number of single case reports have suggested that the context within which intervention studies take place may challenge the assumptions that underpin randomised controlled trials (RCTs). However, the diverse ways in which context may challenge the central tenets of the RCT, and the degree to which this information is known to researchers or subsequently reported, has received much less attention. In this paper, we explore these issues by focusing on seven RCTs of interventions varying in type and degree of complexity, and across diverse contexts. Methods This in-depth multiple case study using interviews, focus groups and documentary analysis was conducted in two phases. In phase one, a RCT of a nurse-led intervention provided a single exploratory case and informed the design, sampling and data collection within the main study. Phase two consisted of a multiple explanatory case study covering a spectrum of trials of different types of complex intervention. A total of eighty-four data sources across the seven trials were accessed. Results We present consistent empirical evidence across all trials to indicate that four key elements of context (personal, organisational, trial and problem context) are crucial to understanding how a complex intervention works and to enable both assessments of internal validity and likely generalisability to other settings. The ways in which context challenged trial operation was often complex, idiosyncratic, and subtle; often falling outside of current trial reporting formats. However, information on such issues appeared to be available via first hand ‘insider accounts’ of each trial suggesting that improved reporting on the role of context is possible. Conclusions Sufficient detail about context needs to be understood and reported in RCTs of complex interventions, in order for the transferability of complex interventions to be assessed. Improved reporting formats that require and encourage the clarification of both general and project-specific threats to the likely internal and external validity need to be developed. In addition, a cultural change is required in which the open and honest reporting of such issues is seen as an indicator of study strength and researcher integrity, rather than a symbol of a poor quality study or investigator ability.

2006-08-01

This study examines the effects of the Availability, Responsiveness, and Continuity (ARC) organizational intervention strategy on caseworker turnover, climate, and culture in a child welfare and juvenile justice system. Using a pre-post, randomized blocks, true experimental design, 10 urban and 16 rural case management teams were randomly assigned to either the ARC organizational intervention condition or to a control condition. The culture and climate of each case management team were assessed at baseline and again after the one-year organizational intervention was completed. In addition, caseworker turnover was assessed by identifying caseworkers on the sampled teams who quit their jobs during the year. Hierarchical Linear Models (HLM) analyses indicate that the ARC organizational intervention reduced the probability of caseworker turnover by two-thirds and improved organizational climate by reducing role conflict, role overload, emotional exhaustion, and depersonalization in both urban and rural case management teams. Organizational intervention strategies can be used to reduce staff turnover and improve organizational climates in urban and rural child welfare and juvenile justice systems. This is important because child welfare and juvenile justice systems in the U.S.A. are plagued by high turnover rates, and there is evidence that high staff turnover and poor organizational climates negatively affect service quality and outcomes in these systems.

This paper presents the cost and cost-effectiveness of the Good School Toolkit (GST), a programme aimed at reducing physical violence perpetrated by school staff to students in Uganda. The effectiveness of the Toolkit was tested with a cluster randomised controlled trial in 42 primary schools in Luwero District, Uganda. A full economic costing evaluation and cost-effectiveness analysis were conducted alongside the trial. Both financial and economic costs were collected retrospectively from the provider's perspective to estimate total and unit costs. The total cost of setting up and running the Toolkit over the 18-month trial period is estimated at US$397 233, excluding process monitor (M&E) activities. The cost to run the intervention is US$7429 per school annually, or US$15 per primary school pupil annually, in the trial intervention schools. It is estimated that the intervention has averted 1620 cases of past-week physical violence during the 18-month implementation period. The total cost per case of violence averted is US$244, and the annual implementation cost is US$96 per case averted during the trial. The GST is a cost-effective intervention for reducing violence against pupils in primary schools in Uganda. It compares favourably against other violence reduction interventions in the region.

To assess the effectiveness and feasibility of behavioral sleep intervention for medicated children with ADHD. Six medicated children (five boys, one girl; aged 6-12 years) with ADHD participated in a 4-week sleep intervention program. The main behavioral strategies used were Faded Bedtime With Response Cost (FBRC) and positive reinforcement. Within a case-series design, objective measure (Sleep Disturbance Scale for Children [SDSC]) and subjective measure (sleep diaries) were used to record changes in children's sleep. For all six children, significant decrease was found in the severity of children's sleep problems (based on SDSC data). Bedtime resistance and mean sleep onset latency were reduced following the 4-week intervention program according to sleep diaries data. Gains were generally maintained at the follow-up. Parents perceived the intervention as being helpful. Based on the initial data, this intervention shows promise as an effective and feasible treatment.

The objectives are to analyze the outcomes of fetal interventions for fetal limb abnormalities associated with amniotic band syndrome (ABS), to compare the outcome with the known natural history, and to establish selection criteria for fetal intervention. In a Medline search, six cases of prenatal fetoscopic interventions for ABS were found. An unpublished case was added. Review of the seven cases of treated ABS in utero suggests that abnormal, but present blood flow at Doppler distal to the area constricted by the band may optimally identify cases suitable for fetal surgery. We propose a prenatal classification in stages of cases of ABS based on ultrasound and Doppler findings. Premature rupture of membranes (PROM) occurred in five patients (71%). The median gestational age (GA) at delivery was 34.8 weeks (range 32 to 39). The median time between procedure and PROM was 6 weeks (range 4 days to 14.3 weeks). The median time between procedure and delivery was 11.8 weeks (range 5-17). The use of a uniform prenatal classification of cases of ABS may allow a more precise correlation of prenatal findings and postnatal outcome. (c) 2009 John Wiley & Sons, Ltd.

The authors consider the challenges to quantifying both the business case and the social case for addressing disparities, which is central to achieving equity in the U.S. health care system. They describe the practical and methodological challenges faced by health plans exploring the business and social cases for undertaking disparity-reducing interventions. Despite these challenges, sound business and quality improvement principles can guide health care organizations seeking to reduce disparities. Place-based interventions may help focus resources and engage health care and community partners who can share in the costs of-and gains from-such efforts.

We investigated the application of Alberta Infant Motor Scale (AIMS) in screening motor development delay in the follow-up of high-risk infants who were discharged from NICU, to explain the state of infants' motor development and propose early individualized intervention. The study design was a randomized, single-blind trial by selecting patients between April 2015 and November 2015 in our hospital, children nerve recovery branch clinics and 77 cases of high-risk infants. We randomly divided the patients into observation group (39 cases) and control group (38 cases). To evaluate the application with AIMS, observation group was based on evaluation results for the first time to give rehabilitation training plan making, early intervention, control group according to the growth and development milestone in order to guide parents to take family training interval of 3 months. While comparing the two groups of high-risk infants before the intervention, the months of age, gender, risk factors, it was found that the AIMS scores, each position AIMS scores did not show a significant difference in percentile (p>0.05). There was also no significant difference between two groups in the seat and stand AIMS scores before and after intervention (p>0.05). However, the comparison of two groups of high-risk infants after intervention in comparison showed that the observation group supine AIMS scores and AIMS scores were significantly higher than the control group (p<0.05). Prone position AIMS scores observation group was also significantly higher than that of the control group (p<0.01). The corresponding percentile for two groups after the intervention of AIMS scores was less than 10% of cases, which was significantly lower in the observation group (p<0.01). AIMS can predict the development delay in high-risk infants, for improving the early hypernymic diagnosis and intervention.

Patients who survive hip fracture are at high risk of recurrent fractures, but rates of osteoporosis treatment 1 year after sustaining a fracture are less than 10% to 20%. We have developed an osteoporosis case manager intervention. The case manager educated patients, arranged bone mineral density tests, provided prescriptions, and communicated with primary care physicians. The intervention was compared with usual care in a randomized controlled trial. We recruited from all hospitals that participate in the Capital Health system (Alberta, Canada), including patients 50 years or older who had sustained a hip fracture and excluding those who were receiving osteoporosis treatment or who lived in a long-term care facility. Primary outcome was bisphosphonate therapy 6 months after fracture; secondary outcomes included bone mineral density testing, appropriate care (bone mineral density testing and treatment if bone mass was low), and intervention costs. We screened 2219 patients and allocated 220, as follows: 110 to the intervention group and 110 to the control group. Median age was 74 years, 60% were women, and 37% reported having had previous fractures. Six months after hip fracture, 56 patients in the intervention group (51%) were receiving bisphosphonate therapy compared with 24 patients in the control group (22%) (adjusted odds ratio, 4.7; 95% confidence interval, 2.4-8.9; P < .001). Bone mineral density tests were performed in 88 patients in the intervention group (80%) vs 32 patients in the control group (29%) (P < .001). Of the 120 patients who underwent bone mineral density testing, 25 (21%) had normal bone mass. Patients in the intervention group were more likely to receive appropriate care than were patients in the control group (67% vs 26%; P < .001). The average intervention cost was $50.00 per patient. For a modest cost, a case manager was able to substantially increase rates of osteoporosis treatment in a vulnerable elderly population at high risk of future fractures.

A small group of frequent visitors to Emergency Departments accounts for a disproportionally large fraction of healthcare consumption including unplanned hospitalizations and overall healthcare costs. In response, several case and disease management programs aimed at reducing healthcare consumption in this group have been tested; however, results vary widely. To investigate whether a telephone-based, nurse-led case management intervention can reduce healthcare consumption for frequent Emergency Department visitors in a large-scale setup. A total of 12 181 frequent Emergency Department users in three counties in Sweden were randomized using Zelen's design or a traditional randomized design to receive either a nurse-led case management intervention or no intervention, and were followed for healthcare consumption for up to 2 years. The traditional design showed an overall 12% (95% confidence interval 4-19%) decreased rate of hospitalization, which was mostly driven by effects in the last year. Similar results were achieved in the Zelen studies, with a significant reduction in hospitalization in the last year, but mixed results in the early development of the project. Our study provides evidence that a carefully designed telephone-based intervention with accurate and systematic patient selection and appropriate staff training in a centralized setup can lead to significant decreases in healthcare consumption and costs. Further, our results also show that the effects are sensitive to the delivery model chosen.

Live case presentations are increasingly common at interventional cardiology conferences. Taking advantage of significant advances in communication technology, broadcasts of procedures can be viewed as an extension of traditional medical education targeted to large groups of practitioners. However, there are important ethical, commercial, and patient safety issues associated with live cases that deserve attention. Use of investigational devices in live case demonstrations is subject to review and approval by FDA's Center for Devices and Radiological Health (CDRH), and the outcomes of patients participating in live cases are considered in the overall clinical study results.

The objective of this systematic review was to examine the effectiveness of the organization of care: case management, multidisciplinary care, multi-faceted treatment, hours of service, outreach programs and health information systems on medical, immunological, virological, psychosocial and economic outcomes for persons living with HIV/AIDS. We searched PubMed (MEDLINE) and 10 other electronic databases from 1 January 1980 to April, 2012 for both experimental and controlled observational studies. Thirty-three studies met the inclusion criteria. Eleven studies were randomized controlled trials (RCTs), three of which were conducted in low-middle income settings. Patient characteristics, study design, organization measures and outcomes data were abstracted independently by two reviewers from all studies. A risk of bias tool was applied to RCTs and a separate tool was used to assess the quality of observational studies. This review concludes that case management interventions were most consistently associated with improvements in immunological outcomes but case management demonstrates no clear association with other outcome measures. The same mixed results were also identified for multidisciplinary and multi-faceted care interventions. Eight studies with an outreach intervention were identified and demonstrated improvements or non-inferiority with respect to mortality, receipt of antiretroviral medications, immunological outcomes, improvements in healthcare utilization and lower reported healthcare costs when compared to usual care. Of the interventions examined in this review, sustained in-person case management and outreach interventions were most consistently associated with improved medical and economic outcomes, in particular antiretroviral prescribing, immunological outcomes and healthcare utilization. No firm conclusions can be reached about the impact of any one intervention on patient mortality.

to estimate the extent to which a case-management intervention for persons newly discharged into the community following an acute stroke effected a change in stroke outcome in comparison with usual care. a re-analysis of stratified, balanced, randomised clinical trial. five university-affiliated acute-care hospitals in Montreal, Quebec, Canada. a total of 190 persons (mean age 70 years) returning home directly from the acute-care hospital following a first or recurrent stroke with a need for health-care supervision post-discharge because of low function, co-morbidity or isolation. for 6 weeks following discharge a nurse case manager delivered, depending on need, over 50 different nursing interventions (range 2-15 per person), which targeted physical, emotional and psychological impairments, role participation restrictions and health perception. seven of the SF-36 subscales were used to measure the targeted constructs, at the post-intervention and 6 month evaluations. Seven binary response variables were created with a change of 10 points the criterion for individual response. Generalised estimating equations, equivalent to a logistic regression for multiple outcomes, were used. the odds of responding to one or more outcomes was 41% greater in the intervention group than in the control group [odds ratio (OR): 1.41; 95% confidence interval (CI): 1.11-1.79]. an analysis considering the complexity of the intervention and outcomes targeted indicated effectiveness of the nurse case-management post-stroke, whereas the traditional one outcome analysis did not.

Disclosure of Financial Conflicts of Interests in Interventions to Improve Child Psychosocial Health: A Cross-Sectional Study.

Eisner, Manuel; Humphreys, David K; Wilson, Philip; Gardner, Frances

2015-01-01

Academic journals increasingly request a full disclosure of financial conflict of interest (CoI). The Committee for Publication Ethics provides editors with guidance about the course of action in the case of suspected non-disclosure. No prior study has examined the extent to which journal articles on psychosocial interventions disclose CoI, and how journal editors process requests to examine suspected undisclosed CoI. Four internationally disseminated psychosocial interventions were examined. 136 articles related to an intervention, co-authored by intervention developers and published in health sciences journals were retrieved as requiring a CoI statement. Two editors refused consent to be included in the study. COI disclosures and editor responses were coded for 134 articles. Overall, 92/134 (71%) of all articles were found to have absent, incomplete or partly misleading CoI disclosures. Disclosure rates for the four programs varied significantly between 11% and 73%. Journal editors were contacted about 92 published articles with no CoI disclosure or a disclosure that was considered problematic. In 65/92 (71%) of all cases the editors published an 'erratum' or 'corrigendum'. In 16 of these cases the journal had mishandled a submitted disclosure. The most frequent reason for non-publication of an erratum was that the journal had no disclosure policy at the time of the publication (16 cases). Consumers of research on psychosocial interventions published in peer-reviewed journals cannot currently assume that CoI disclosures are adequate and complete. More efforts are needed to achieve transparency.

Musculoskeletal injuries among health care workers is very high, particularly so in direct care workers involved in patient handling. Efforts to reduce injuries have shown mixed results, and strong evidence for intervention effectiveness is lacking. The purpose of our study was to evaluate the effectiveness of a Transfer, Lifting and Repositioning (TLR) program to reduce musculoskeletal injuries (MSI) among direct health care workers. This study was a pre- and post-intervention design, utilizing a nonrandomized control group. Data were collected from the intervention group (3 hospitals; 411 injury cases) and the control group (3 hospitals; 355 injury cases) for periods 1 year pre- and post-intervention. Poisson regression analyses were performed. Of a total 766 TLR injury cases, the majority of injured workers were nurses, mainly with back, neck, and shoulder body parts injured. Analysis of all injuries and time-loss rates (number of injuries/100 full-time employees), rate ratios, and rate differences showed significant differences between the intervention and control groups. All-injuries rates for the intervention group dropped from 14.7 pre-intervention to 8.1 post-intervention. The control group dropped from 9.3 to 8.4. Time-loss injury rates decreased from 5.3 to 2.5 in the intervention group and increased in the control group (5.9 to 6.5). Controlling for group and hospital size, the relative rate of all-injuries and time-loss injuries for the pre- to post-period decreased by 30% (RR = 0.693; 95% CI = 0.60-0.80) and 18.6% (RR = 0.814; 95% CI = 0.677-0.955), respectively. The study provides evidence for the effectiveness of a multifactor TLR program for direct care health workers, especially in small hospitals.

To develop a framework for the management of complex health care interventions within the Deming continuous improvement cycle and to test the framework in the case of an integrated intervention for multimorbid patients in the Basque Country within the CareWell project. Statistical analysis alone, although necessary, may not always represent the practical significance of the intervention. Thus, to ascertain the true economic impact of the intervention, the statistical results can be integrated into the budget impact analysis. The intervention of the case study consisted of a comprehensive approach that integrated new provider roles and new technological infrastructure for multimorbid patients, with the aim of reducing patient decompensations by 10% over 5 years. The study period was 2012 to 2020. Given the aging of the general population, the conventional scenario predicts an increase of 21% in the health care budget for care of multimorbid patients during the study period. With a successful intervention, this figure should drop to 18%. The statistical analysis, however, showed no significant differences in costs either in primary care or in hospital care between 2012 and 2014. The real costs in 2014 were by far closer to those in the conventional scenario than to the reductions expected in the objective scenario. The present implementation should be reappraised, because the present expenditure did not move closer to the objective budget. This work demonstrates the capacity of budget impact analysis to enhance the implementation of complex interventions. Its integration in the context of the continuous improvement cycle is transferable to other contexts in which implementation depth and time are important.

Background: Several studies have highlighted the implications of impulsivity and novelty seeking for both the maintenance and the process of recovery from bulimia nervosa (BN). Cognitive behavioral therapy (CBT) is the treatment of choice for BN, but for some cases, this treatment alone might not be sufficient for reducing the high levels of impulsivity. The paper presents a case report of a patient with BN, examining the effectiveness of using a videogame (VG; Playmancer) as an additional intervention designed to address impulsivity. Design: Psychometric and neuropsychological measures were collected at baseline. After this assessment, Playmancer was applied prior to CBT, following an “A-B-A-C-A” single case experimental design. Impulsivity levels were assessed with the Conner’s Continuous Performance Test II (CPT-II). After the Playmancer treatment, the patient started CBT, and the levels of impulsivity were recorded again. Finally, psychometric and neuropsychological measures were collected after treatment. Weekly frequency of binges and vomiting were also recorded during the entire procedure. Results: After the VG intervention, psychometric measures such as anxiety levels, impulsivity and novelty seeking decreased. Regarding the neuropsychological measures, impulsivity levels (measured with the CPT-II) progressively decreased throughout the intervention, and an improvement in decision making capacities was observed. Furthermore, the frequency of binges also decreased during and after the VG intervention. Discussion: This case report suggests that using the Playmancer VG to reduce impulsivity prior to CBT may enhance the final results of the treatment for BN. PMID:26236261

To evaluate success rates in controlling intraocular pressure (IOP) after implantation of a second glaucoma drainage device (GDD) with a Baerveldt glaucoma implant in patients with refractory glaucoma, with a secondary aim of reducing the need for postoperative glaucoma medications. This retrospective, noncomparative, interventional study included patients undergoing a second GDD for uncontrolled glaucoma from a tertiary care glaucoma service. Data were obtained from the medical records for the preoperative period and after the 1st, 15th, and 30th day, 3, 6, and 12 months, and then yearly until the last postoperative visit. Visual acuity, IOP, and number of glaucoma medications (NGM) from the follow-up visits were compared to baseline. Success and failure criteria were analyzed based on IOP level or need of glaucoma medications. Forty-nine patients were studied, with a mean follow-up time of 25 ± 21 months. The mean preoperative IOP was 23.7 ± 8.2 mmHg, and decreased to 14.8 ± 4.0 mmHg after 1 year, 14.4 ± 3.9 mmHg after 2 years, and 16.6 ± 8.5 mmHg after 3 years. The mean preoperative NGM was 3.4 ± 1.3, and decreased to 2.0 ± 1.8 after 1 year, 2.5 ± 1.6 after 2 years, and 2.8 ± 2.0 after 3 years. Absolute success was 9% after 1 year for a postoperative IOP between 5 and 18 mmHg, and 76% for a postoperative IOP between 5 and 21 mmHg. The qualified success was 88% at the first and second years and 83% at the third year. With up to 3 years of follow-up, a second glaucoma drainage device was successful in reducing IOP to below 21 mmHg, but not as successful below 18 mmHg. The success rate is improved with the use of glaucoma medications with up to 3 years of follow-up.

Propensity score matching for selection of local areas as controls for evaluation of effects of alcohol policies in case series and quasi case-control designs.

Area-level public health interventions can be difficult to evaluate using natural experiments. We describe the use of propensity score matching (PSM) to select control local authority areas (LAU) to evaluate the public health impact of alcohol policies for (1) prospective evaluation of alcohol policies using area-level data, and (2) a novel two-stage quasi case-control design. Ecological. Alcohol-related indicator data (Local Alcohol Profiles for England, PHE Health Profiles and ONS data) were linked at LAU level. Six LAUs (Blackpool, Bradford, Bristol, Ipswich, Islington, and Newcastle-upon-Tyne) as sample intervention or case areas were matched to two control LAUs each using PSM. For the quasi case-control study a second stage was added aimed at obtaining maximum contrast in outcomes based on propensity scores. Matching was evaluated based on average standardized absolute mean differences (ASAM) and variable-specific P-values after matching. The six LAUs were matched to suitable control areas (with ASAM < 0.20, P-values >0.05 indicating good matching) for a prospective evaluation study that sought areas that were similar at baseline in order to assess whether a change in intervention exposure led to a change in the outcome (alcohol related harm). PSM also generated appropriate matches for a quasi case-control study--whereby the contrast in health outcomes between cases and control areas needed to be optimized in order to assess retrospectively whether differences in intervention exposure were associated with the outcome. The use of PSM for area-level alcohol policy evaluation, but also for other public health interventions, will improve the value of these evaluations by objective and quantitative selection of the most appropriate control areas.

Public Health Interventions and SARS Spread, 2003

PubMed Central

2004-01-01

The 2003 outbreak of severe acute respiratory syndrome (SARS) was contained largely through traditional public health interventions, such as finding and isolating case-patients, quarantining close contacts, and enhanced infection control. The independent effectiveness of measures to "increase social distance" and wearing masks in public places requires further evaluation. Limited data exist on the effectiveness of providing health information to travelers. Entry screening of travelers through health declarations or thermal scanning at international borders had little documented effect on detecting SARS cases; exit screening appeared slightly more effective. The value of border screening in deterring travel by ill persons and in building public confidence remains unquantified. Interventions to control global epidemics should be based on expert advice from the World Health Organization and national authorities. In the case of SARS, interventions at a country's borders should not detract from efforts to identify and isolate infected persons within the country, monitor or quarantine their contacts, and strengthen infection control in healthcare settings.

2016-03-01

The study presented in this paper aims to identify prominent risks leading to heat illness in summer among construction workers that can be prioritised for developing effective interventions. Samples are 216 construction workers' cases at the individual level and 26 construction projects cases at the organisation level. A grounded theory is generated to define the climatic heat and psychosocial risks and the relationships between risks, timing and effectiveness of interventions. The theoretical framework is then used to guide content analysis of 36 individual onsite heat illness cases to identify prominent risks. The results suggest that heat stress risks on construction site are socially constructed and can be effectively managed through elimination at supply chain level, effective engineering control, proactive control of the risks through individual interventions and reactive control through mindful recognition and response to early symptoms. The role of management infrastructure as a base for effective interventions is discussed. Copyright © 2015 Elsevier Ltd and The Ergonomics Society. All rights reserved.

Introduction The number of persons aged over 90 years will grow significantly in coming decades. This group has the highest rates of dementia, most commonly Alzheimer’s disease (AD). Methods Using The 90+ Study we developed a statistical model for dementia risk based on brain pathologies. Intervention scenarios which reduce or eliminate AD pathology were considered and the numbers of dementia cases among the U.S. oldest-old that could be prevented were estimated. Results U.S. dementia prevalence among the oldest-old will increase from 1.35 million in 2015 to 4.72 million in 2050.If interventions eliminate AD pathology, dementia prevalence would be reduced by approximately 50%, averting nearly 2.4 million cases in 2050. However, large numbers of dementia cases would still remain. Discussion Reducing AD pathology would significantly decrease the public health burden of dementia. However, other interventions are needed to address the burden associated with other dementing pathologies prevalent in the oldest-old. PMID:26900132

Despite the prevalence of evidence-based interventions to improve quality in health care systems, there is a paucity of documented evidence of a financial return on investment (ROI) for these interventions from the perspective of the investing entity. To report on a demonstration project designed to measure the business case for selected quality interventions in high-risk high-cost patient populations in 10 Medicaid managed care organizations across the United States. Using claims and enrollment data gathered over a 3-year period and data on the costs of designing, implementing, and operating the interventions, ROIs were computed for 11 discrete evidence-based quality-enhancing interventions. A complex case management program to treat adults with multiple comorbidities achieved the largest ROI of 12.21:1. This was followed by an ROI of 6.35:1 for a program which treated children with asthma with a history of high emergency room (ER) use and/or inpatient admissions for their disease. An intervention for high-risk pregnant mothers produced a 1.26:1 ROI, and a program for adult patients with diabetes resulted in a 1.16:1 return. The remaining seven interventions failed to show positive returns, although four sites came close to realizing sufficient savings to offset investment costs. Evidence-based interventions designed to improve the quality of patient care may have the best opportunity to yield a positive financial return if it is focused on high-risk high-cost populations and conditions associated with avoidable emergency and inpatient utilization. Developing the necessary tracking systems for the claims and financial investments is critical to perform accurate financial ROI analyses.

We compared use of community medicine distributors (CMDs) and drug use under integrated community case management and home-based management strategies in children 6–59 months of age in eastern Uganda. A cross-sectional study with 1,095 children was nested in a cluster randomized trial with integrated community case management (CMDs treating malaria and pneumonia) as the intervention and home-based management (CMDs treating only malaria) as the control. Care-seeking from CMDs was higher in intervention areas (31%) than in control areas (22%; P = 0.01). Prompt and appropriate treatment of malaria was higher in intervention areas (18%) than in control areas (12%; P = 0.03) and among CMD users (37%) than other health providers (9%). The mean number of drugs among CMD users compared with other health providers was 1.6 versus 2.4 in intervention areas and 1.4 versus 2.3 in control areas. Use of CMDs was low. However, integrated community case management of childhood illnesses increased use of CMDs and rational drug use. PMID:23136276

Objectives. To evaluate the feasibility of implementing a statewide children with special health care needs (CSHCN) program evaluation, case management, and surveillance system using a standardized instrument and protocol that operationalized the United States Health and Human Services CSHCN National Performance Measures. Methods. Public health nurses in local public health agencies in Washington State jointly developed and implemented the standardized system. The instrument was the Omaha System. Descriptive statistics were used for the analysis of standardized data. Results. From the sample of CSHCN visit reports (n = 127), 314 problems and 853 interventions were documented. The most common problem identified was growth and development followed by health care supervision, communication with community resources, caretaking/parenting, income, neglect, and abuse. The most common intervention category was surveillance (60%), followed by case management (24%) and teaching, guidance, and counseling (16%). On average, there were 2.7 interventions per problem and 6.7 interventions per visit. Conclusions. This study demonstrates the feasibility of an approach for statewide CSHCN program evaluation, case management, and surveillance system. Knowledge, behavior, and status ratings suggest that there are critical unmet needs in the Washington State CSHCN population for six major problems. PMID:23533804

Excess of non-verbal cases of autism spectrum disorders presenting to orthodox clinical practice in Africa – a trend possibly resulting from late diagnosis and intervention

Bakare, Muideen O; Munir, Kerim M

2012-01-01

Objectives Characteristics of children with autism spectrum disorders (ASDs) in Africa are not known because of unavailability of large-scale epidemiological studies in this region. This review explored the age at first presentation to orthodox clinical practice of African children with ASDs and their expressive language ability at presentation. Methods A literature search of case series and case reports of ASDs from Africa was done through PubMed/MEDLINE, Google Scholar, African Journals Online (AJOL), and archives of the Nigerian Journal of Psychiatry. Six articles included content relating to age of the child at first presentation to orthodox clinical practice and symptoms at presentation related to expressive language ability and therefore fulfilled the inclusion criteria. Suggestions are made to explain the observations emanating from the review. Results An excess of non-verbal over verbal cases of ASDs have been presenting to orthodox clinical practice and there is a common denominator of late presentation/diagnosis and in turn late intervention, with most cases presenting for the first time well above 8 years of age. Attempts to explain these observations included low levels of knowledge and awareness about ASDs in Africa; problems with help-seeking behaviour; and lack of mental healthcare facilities and trained personnel. Conclusions Enhancement of processes directed at ensuring early diagnosis and interventions, especially interventions aimed at improving speech and language development well and sufficiently early, may bring about a shift in the trend of excess non-verbal cases of ASDs over verbal cases presenting to orthodox clinical practice.

Meanwhile, correctional programs used to treat a variety of offenders (e.g., substance users, violent offenders, and so forth) that adhere to the "principles of effective intervention" (PEI) have reported significant reductions in recidivism. This article introduces the PEI-the principles on which evidence-based practices in correctional rehabilitation are based-and identifies the degree to which they are currently integrated into BIPs. The case is made that batterer programs could be more effective if they incorporate the PEI. Recommendations for further integration of the principles into BIPs are also provided. © The Author(s) 2015.

Research suggests motivational interviewing (MI) techniques are both widely-used by educational psychologists (EPs) and effective in supporting young people of secondary age. To date, there has been no published research investigating the use of MI with primary-aged children. This study details the use of a short MI-based intervention with a primary-aged pupil identified as disengaged. A case-based approach was employed, using pupil and teacher interviews and observational fieldnotes to assess the usefulness of the intervention. Data were analysed using thematic analysis and the intervention checked for adherence to the MI spirit and principles. Here the process, structure and outcomes of the intervention are exemplified through an illustrative case study with a nine-year-old boy. Results indicate that the adapted intervention had a significant impact on learning motivation and classroom behaviour. The implications of the findings are discussed in relation to the use of school-based therapeutic interventions by EPs. PMID:26339113

Although street-based female sex workers (FSWs) are highly vulnerable to HIV, they often lack access to needed health services and medical care. This paper reports the results of a recently completed randomized intervention trial for FSWs in Miami, Florida, which tested the relative efficacy of two case management interventions that aimed to link underserved FSWs with health services and to reduce risk behaviors for HIV. Participants were recruited using targeted sampling strategies and were randomly assigned to: a Strengths-Based/Professional Only (PO) or a Strengths-Based/Professional-Peer condition (PP). Follow-up data were collected 3 and 6 months post-baseline. Outcome analyses indicated that both intervention groups displayed significant reductions in HIV risk behaviors and significant increases in services utilization; the Professional-Peer condition provided no added benefit. HIV seropositive FSWs responded particularly well to the interventions, suggesting the utility of brief strengths-based case management interventions for this population in future initiatives.

This study was performed to assess the applicability of the WHO Maternal Near Miss Tool (MNM Tool) and the organ dysfunction criteria in a high-income country. The MNM tool was applied to 2552 women who died of pregnancy-related causes or sustained severe acute maternal morbidity between August 2004 and August 2006 in one of the 98 hospitals with a maternity unit in the Netherlands. Fourteen (0.6%) cases had insufficient data for application. Each case was assessed according to the three main "MNM categories" specified in the MNM tool and their subcategory criteria: five disease-, four intervention- and seven organ dysfunction-based criteria. Potentially life-threatening conditions (disease-based inclusions) and life-threatening cases (organ dysfunction-based inclusions) were differentiated according to WHO methodology. Outcomes were incidence of all (sub)categories and case-fatality rates. Of the 2538 cases, 2308 (90.9%) women fulfilled disease-based, 2116 (83.4%) intervention-based and 1024 (40.3%) organ dysfunction-based criteria. Maternal death occurred in 48 women, of whom 23 (47.9%) fulfilled disease-based, 33 (68.8%) intervention-based and 31 (64.6%) organ dysfunction-based criteria. Case-fatality rates were 23/2308 (1.0%) for cases fulfilling the disease-based criteria, 33/2116 (1.6%) for intervention-based criteria and 31/1024 (3.0%) for women fulfilling the organ dysfunction-based criteria. In the Netherlands, where advanced laboratory and clinical monitoring are available, organ dysfunction-based criteria of the MNM tool failed to identify nearly two-thirds of sustained severe acute maternal morbidity cases and more than one-third of maternal deaths. Disease-based criteria remain important, and using only organ dysfunction-based criteria would lead to underestimating severe acute maternal morbidity. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Little is known about the scope of practice and outcomes in pediatric surgery performed by humanitarian organizations in resource-poor settings and conflict zones. This study provides the largest report to date detailing such data for a major nongovernmental organization providing humanitarian surgical relief support in these settings. To characterize pediatric surgical care provision by a major nongovernmental organization in specialized humanitarian settings and conflict zones. A retrospective cohort study was conducted from August 15, 2014, to March 9, 2015, of 59,928 surgical interventions carried out from January 1, 2012, to December 31, 2013, by the Médecins Sans Frontières Operational Centre Paris (MSF-OCP) program in 20 locations, including South Sudan, Yemen, Syria, Gaza, Pakistan, Nigeria, Central African Republic, Democratic Republic of Congo, and the Philippines. Surgical interventions were primarily for general surgical, traumatic, and obstetric emergencies and were categorized by mechanism, type of intervention, American Society of Anesthesia risk classification, and urgency of intervention. Operative indications, type of intervention, and operative case mortality. Among all age groups, 59,928 surgical interventions were performed in dedicated trauma, obstetric, and reconstructive centers for 2 years. Nearly one-third of interventions (18,040 [30.1%]) involved preteen patients (aged <13 years) and 4571 (7.6%) involved teenaged patients (aged 13-17 years). The proportion of violence-related injuries in the preteen group was significantly lower than in the teenage group (4.8% vs 17.5%; P < .001). Burns (50.1%), other accidental injuries (16.4%), and infections (23.4%) composed the bulk of indications in the preteen group. Interventions in the teenage group were principally caused by trauma-related injuries (burns, 22.9%; traffic accidents, 10.1%; gunshot wounds, 8.0%). Crude perioperative case mortality rates were 0.07% in the preteen group, 0.15% in the teenage group, and 0.22% in the adult group (>17 years) (P = .001). One-third of the cases (33.4%) were deemed urgent, while most of the remaining cases (57.7%) were deemed semielective (surgical intervention to be performed within 48 hours). When examining surgical interventions in a population of pediatric patients cared for in the specialized setting of humanitarian aid and conflict zones, burns, other accidental injuries, and infection composed the bulk of indications in the preteen group; interventions in the teenage group were principally caused by trauma-related injuries. Crude perioperative case mortality rates in the preteen group were significantly lower than in the adult group. Further work is needed to examine long-term outcomes of pediatric operations in these settings and to guide context-specific surgical program development.

Reducing Alaska Native paediatric oral health disparities: a systematic review of oral health interventions and a case study on multilevel strategies to reduce sugar-sweetened beverage intake

2013-01-01

Background Tooth decay is the most common paediatric disease and there is a serious paediatric tooth decay epidemic in Alaska Native communities. When untreated, tooth decay can lead to pain, infection, systemic health problems, hospitalisations and in rare cases death, as well as school absenteeism, poor grades and low quality-of-life. The extent to which population-based oral health interventions have been conducted in Alaska Native paediatric populations is unknown. Objective To conduct a systematic review of oral health interventions aimed at Alaska Native children below age 18 and to present a case study and conceptual model on multilevel intervention strategies aimed at reducing sugar-sweetened beverage (SSB) intake among Alaska Native children. Design Based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) Statement, the terms “Alaska Native”, “children” and “oral health” were used to search Medline, Embase, Web of Science, GoogleScholar and health foundation websites (1970–2012) for relevant clinical trials and evaluation studies. Results Eighty-five studies were found in Medline, Embase and Web of Science databases and there were 663 hits in GoogleScholar. A total of 9 publications were included in the qualitative review. These publications describe 3 interventions that focused on: reducing paediatric tooth decay by educating families and communities; providing dental chemotherapeutics to pregnant women; and training mid-level dental care providers. While these approaches have the potential to improve the oral health of Alaska Native children, there are unique challenges regarding intervention acceptability, reach and sustainability. A case study and conceptual model are presented on multilevel strategies to reduce SSB intake among Alaska Native children. Conclusions Few oral health interventions have been tested within Alaska Native communities. Community-centred multilevel interventions are promising approaches to improve the oral and systemic health of Alaska Native children. Future investigators should evaluate the feasibility of implementing multilevel interventions and policies within Alaska Native communities as a way to reduce children's health disparities.

Undergraduate medical teaching in occupational health (OH) is a challenge in universities around the world. Case-based e-learning with an attractive clinical context could improve the attitude of medical students towards OH. The study question is whether case-based e-learning for medical students is more effective in improving knowledge, satisfaction and a positive attitude towards OH than non-case-based textbook learning. Participants, 141 second year medical students, were randomised to either case-based e-learning or text-based learning. Outcome measures were knowledge, satisfaction and attitude towards OH, measured at baseline, directly after the intervention, after 1 week and at 3-month follow-up. Of the 141 participants, 130 (92%) completed the questionnaires at short-term follow-up and 41 (29%) at 3-month follow-up. At short-term follow-up, intervention and control groups did not show a significant difference in knowledge nor satisfaction but attitude towards OH was significantly more negative in the intervention group (F=4.041, p=0.047). At 3-month follow-up, there were no significant differences between intervention and control groups for knowledge, satisfaction and attitude. We found a significant decrease in favourable attitude during the internship in the experimental group compared with the control group. There were no significant differences in knowledge or satisfaction between case-based e-learning and text-based learning. The attitude towards OH should be further investigated as an outcome of educational programmes.

An increasing number of studies have shown the beneficial effects of both recreational and therapeutic interventions assisted by animals for children with Autism Spectrum Disorders (ASD). The observed effects are believed to be mainly due to the ability of some animals to positively engage people, thus potentially counteracting the social withdrawal characterizing these subjects. Here we report the case of a child with high-functioning autism who has been included in an Equine-Assisted Intervention (EAI) program for 2 years. In particular, the relationship with the animal was used to encourage child’s narrative abilities as a primary means of improving cognition and communication. This case represents a first attempt to theorize the role of human-animal interaction as an adjunct to classic therapeutic strategies in ASD. During the intervention, the child appeared to gradually abandon his attitude to avoid the contact with the present and to hide in imaginative past and future. We propose animal-assisted interventions as complementary approaches capable to facilitate the verbalization of the patient’s internal states and to promote psychological well-being through the development of a bond with the animal.

This study analyzed the content of 125 unique reports published since 1990 that have examined the health and well-being—as well as the interpersonal and contextual experiences—of sexual minority youth of color (SMYoC). One-half of reports sampled only young men, 73% were noncomparative samples of sexual minority youth, and 68% of samples included multiple racial-ethnic groups (i.e., 32% of samples were mono-racial/ethnic). Most reports focused on health-related outcomes (i.e., sexual and mental health, substance use), while substantially fewer attended to normative developmental processes (i.e., identity development) or contextual and interpersonal relationships (i.e., family, school, community, or violence). Few reports intentionally examined how intersecting oppressions and privileges related to sexual orientation and race-ethnicity contributed to outcomes of interest. Findings suggest that research with SMYoC has been framed by a lingering deficit perspective, rather than emphasizing normative developmental processes or cultural strengths. The findings highlight areas for future research focused on minority stress, coping, and resilience of SMYoC. PMID:28367257

Tails of the Travelling Gaussian model and the relative age effect: Tales of age discrimination and wasted talent

2017-01-01

The Relative Age Effect (RAE) documents the inherent disadvantages of being younger rather than older in an age-banded cohort, typically a school- or competition-year, to the detriment of career-progression, earnings and wellbeing into adulthood. We develop the Tails of the Travelling Gaussian (TTG) to model the mechanisms behind RAE. TTG has notable advantages over existing approaches, which have been largely descriptive, potentially confounded, and non-comparable across contexts. In Study 1, using data from the UK’s Millennium Cohort Study, we investigate the different levels of RAE bias across school-level academic subjects and “personality” traits. Study 2 concerns biased admissions to elite English Premier League soccer academies, and shows the model can still be used with minimal data. We also develop two practical metrics: the discrimination index (ID), to quantify the disadvantages facing cohort-younger children; and the wastage metric (W), to quantify the loss through untapped potential. TTG is sufficiently well-specified to simulate the consequences of ID and W for policy change. PMID:28426748

To report the long-term efficacy of custom polymethyl methacrylate implants using high-resolution computed tomographic modeling in the reconstruction of complex orbitofacial defects secondary to trauma. Nine patients with complex orbitofacial bone defects after trauma were evaluated for this retrospective, nonrandomized, noncomparative study. All the patients underwent reconstruction using custom, heat-cured polymethyl methacrylate implants. Patients were followed up postoperatively and evaluated for complications. Nine consecutive patients (5 men and 4 women) aged 28 to 63 years who underwent surgical reconstruction using prefabricated, heat-cured polymethyl methacrylate implants were included in the study. The interval between injury and presentation ranged from 1 month to 40 years. There were no significant complications, including infection, extrusion, or displacement of the implant. In all of the patients, wound healing was uneventful, with antibiotic drugs administered perioperatively. Mean follow-up was 4.3 years from the first visit (range, 6 months to 10 years). Computed tomographic biomodeled, prefabricated, heat-cured polymethyl methacrylate implants are well tolerated in the long term. Their advantages include customized design, long-term biocompatibility, and excellent aesthetic results.

The aim of this work was to evaluate in an open, noncomparative study the use of secnidazole in oral suspension given to Venezuelan children infected with Giardia intestinalis, from a community in Carapita, a slum area in Caracas. Seventy children from 2 to 11 years old (38 males and 32 females) were treated with a single oral dose of secnidazole (30 mg/Kg of body weight), after clinical and parasitological evaluation to make the diagnosis of active giardiasis. The effectiveness of treatment was determined by clinical examination and parasitological evaluation of feces samples 15 days after treatment. The results showed 95% of clinical cure with a significant decrease of the frequency of gastrointestinal symptoms. The parasitological cure was 98%, there were 4 failures at the end of treatment. Side effects observed after treatment were of mild intensity, lasting only few hours. These results show that a simple dose of secnidazole in an oral suspension is an effective, safe and well tolerated treatment for giardiasis in children and that this drug may be used as a mass treatment in risk populations.

Strategies to enhance the anticancer potential of TNF.

PubMed

Pilati, Pierluigi; Rossi, Carlo Riccardo; Mocellin, Simone

2008-01-01

Although tumor necrosis factor (TNF) antitumor activity is evident in several preclinical models and in non-comparative clinical trials, no evidence exists that TNF-based treatments increase patient survival. Furthermore, due to systemic toxicity, TNF can only be administered via sophisticated drug-delivery systems in patients with solid tumors confined to one extremity or organ. The impossibility to administer TNF systemically does not allow to test the effectiveness of this cytokine in other clinical settings for the treatment of a broader spectrum of tumor types. Dissecting the cascade of molecular events underlying tumor sensitivity to TNF researchers will allow to further exploit the anticancer potential of this molecule. The rational for the development of strategies aimed at sensitizing malignant cells to TNF is to modulate tumor-specific molecular derangements in order to maximize the selectivity of TNF cytotoxicity towards cancer. This would enhance the anticancer activity of current TNF-based locoregional regimens and would pave the way to the systemic administration of this cytokine and thus to a much wider clinical experimentation of TNF in the oncology field.

Objective To describe the ocular signs and symptoms of patients complaining of eye irritation due to volcanic fog (vog). Methods The study utilized a non-comparative, retrospective chart review of 30 patients who had a chief complaint of eye irritation, which the subjects attributed to vog. Ocular signs and symptoms are described and related to the ambient concentration of sulfur dioxide (SO2), particulate matter sized 2.5 microns (PM2.5), and vog visibility in O‘ahu during the period of the study. Results Ocular signs noted were conjunctival injection (100%), clear mucous discharge (100%), papillary reaction (100%), punctal edema (80%), eyelid swelling (73.3%) and chemosis (63.3%). Ocular symptoms were itchiness (100%), foreign body sensation (100%), tearing (96.6%) and burning sensation (90%). All patients had concurrent respiratory symptoms. During the period of study, the highest 24-hour average concentration of particulate matter sized 2.5 microns (PM2.5) was 49.04 µg/m3 and vog was visually present. Conclusions Patients complaining of eye irritation due to vog have observable ocular signs and symptoms. PMID:22187513

Chemical peeling is a skin-wounding procedure that may have some potentially undesirable side-effects. The present study is directed towards safety concerns associated with superficial chemical peeling with salicylic acid in various facial dermatoses. The study was a non-comparative and a prospective one. Two hundred and sixty-eight patients of either sex, aged between 10 to 60 years, undergoing superficial chemical peeling for various facial dermatoses (melasma, acne vulgaris, freckles, post-inflammatory scars/pigmentation, actinic keratoses, plane facial warts, etc.) were included in the study. Eight weekly peeling sessions were carried out in each patient. Tolerance to the procedure and any undesirable effects noted during these sessions were recorded. Almost all the patients tolerated the procedure well. Mild discomfort, burning, irritation and erythema were quite common but the incidence of major side-effects was very low and these too, were easily manageable. There was no significant difference in the incidence of side-effects between facial dermatoses (melasma, acne and other pigmentary disorders). Chemical peeling with salicylic acid is a well tolerated and safe treatment modality in many superficial facial dermatoses.

Noncomparative scaling of aromaticity through electron itinerancy

Paul, Satadal; Goswami, Tamal; Misra, Anirban

2015-10-01

Aromaticity is a multidimensional concept and not a directly observable. These facts have always stood in the way of developing an appropriate theoretical framework for scaling of aromaticity. In the present work, a quantitative account of aromaticity is developed on the basis of cyclic delocalization of π-electrons, which is the phenomenon leading to unique features of aromatic molecules. The stabilization in molecular energy, caused by delocalization of π-electrons is obtained as a second order perturbation energy for archetypal aromatic systems. The final expression parameterizes the aromatic stabilization energy in terms of atom to atom charge transfer integral, onsite repulsion energy and the population of spin orbitals at each site in the delocalized π-electrons. An appropriate computational platform is framed to compute each and individual parameter in the derived equation. The numerical values of aromatic stabilization energies obtained for various aromatic molecules are found to be in close agreement with available theoretical and experimental reports. Thus the reliable estimate of aromaticity through the proposed formalism renders it as a useful tool for the direct assessment of aromaticity, which has been a long standing problem in chemistry.

Aims Infliximab, an anti-tumour necrosis factor-α monoclonal antibody, is indicated in rheumatoid arthritis (RA). Our objective was to evaluate the influence of the sources of infliximab pharmacokinetic variability in RA. Methods Eighty-four patients treated with infliximab for RA were included in a prospective noncomparative study. They were analysed between two consecutive infliximab infusions. Infliximab concentrations were measured before the infusion, 2 h, 1 and 4 weeks after the infusion and immediately before the next infusion. Infliximab concentrations were described using a two-compartment population pharmacokinetic model. Results The mean (interindividual standard deviation) estimated central volume of distribution was 2.3 l (36%) and systemic clearance was 0.019 l h−1 (37%). The central volume of distribution increased with bodyweight; it was doubled between 50 and 90 kg. Systemic clearance increased with pre-infusion C-reactive protein concentration by 20%, varying from 3 to 14 mg l−1, and was decreased by 30% when methotrexate was coadministered. Conclusions The influence of methotrexate and inflammation on infliximab clearance suggests that individual adjustment of infliximab doses according to disease activity may be useful in RA.

The aim of this study was to investigate whether a multidimensional public-private partnership intervention, focussing on improving the quality and efficiency of sickness benefit case management, reduced the sickness benefit duration and the duration until self-support. We used a difference-in-difference (DID) design with six intervention municipalities and 12 matched control municipalities in Denmark. The study sample comprised 282,103 sickness benefit spells exceeding four weeks. The intervention group with 110,291 spells received the intervention, and the control group with 171,812 spells received ordinary sickness benefit case management. Using register data, we fitted Cox proportional hazard ratio models, estimating hazard ratios (HR) and confidence intervals (CI). We found no joint effect of the intervention on the sickness benefit duration (HR 1.02, CI 0.97-1.07) or the duration until self-support (HR 0.99, CI 0.96-1.02). The effect varied among the six municipalities, with sickness benefit HRs ranging from 0.96 (CI 0.93-1.00) to 1.13 (CI 1.08-1.18) and self-support HRs ranging from 0.91 (CI 0.82-1.00) to 1.11 (CI 1.06-1.17). Compared to receiving ordinary sickness benefit management the intervention had on average no effect on the sickness benefit duration or duration until self-support. However, the effect varied considerably among the six municipalities possibly due to differences in the implementation or the complexity of the intervention.

Decrease in shigellosis-related deaths without Shigella spp.-specific interventions, Asia.

Bardhan, Pradip; Faruque, A S G; Naheed, Aliya; Sack, David A

2010-11-01

In 1999, a review of the literature for 1966-1997 suggested that ≈1.1 million persons die annually of shigellosis, including ≈880,000 in Asia. Our recent review of the literature for 1990-2009 indicates that ≈125 million shigellosis cases occur annually in Asia, of which ≈14,000 are fatal. This estimate for illnesses is similar to the earlier estimate, but the number of deaths is 98% lower; that is, the lower estimate of deaths is associated with markedly reduced case-fatality rates rather than fewer cases. Shigella spp.-related deaths decreased substantially during a period without Shigella spp.-specific interventions. We speculate that nonspecific interventions, e.g., measles vaccination, vitamin A supplementation, and improved nutrition, may have led to the reduced number of shigellosis-related deaths.

The Feldenkrais Method(®) can enhance cognitive function in independent living older adults: A case-series.

Poor cognitive health a major concern of aging individuals, can compromise independent living. More than 16 million people in the United States are affected by cognitive impairment. We have studied the effects of the Feldenkrais Method(®) on cognitive function. In this case series with three participants cognitive function was assessed with the Trail Making Test A and B at baseline and after the Feldenkrais intervention. All participants improved performance on Trail Making Test A and B after completing the Feldenkrais intervention indicating that Feldenkrais lessons may offset age-related decline in cognitive function. The results of this case series warrant larger scale studies on cognitive outcomes of Feldenkrais interventions in clinical and non-clinical populations. Copyright © 2015 Elsevier Ltd.

2015-03-01

Microlaryngoscopy and bronchoscopy procedures (MLBs) are short-duration, high-acuity procedures that carry risk. Poor case flow and communication exacerbate such potential risk. Efficient operative flow is critical for patient safety and resource expenditure. To identify areas for improvement and evaluate the effectiveness of a multidisciplinary quality-improvement (QI) initiative. A QI project using the "Plan-Do-Study-Act" (PDSA) cycle was implemented to assess MLBs performed on pediatric patients in a tertiary academic children's hospital. Forty MLBs were audited using a QI evaluation tool containing 144 fields. Each MLB was evaluated for flow, communication, and timing. Opportunities for improvement were identified. Subsequently, QI interventions were implemented in an iterative cycle, and 66 MLBs were audited after the intervention. Specific QI interventions addressed issues of personnel frequently exiting the operating room (OR) and poor preoperative preparation, identified during QI audit as areas for improvement. Interventions included (1) conducting "huddles" between surgeon and OR staff to discuss needed equipment; (2) implementing improvements to surgeon case ordering and preference cards review; (3) posting an OR door sign to limit traffic during airway procedures; and (4) discouraging personnel breaks during airway procedures. Operating room exiting behavior of OR personnel, preoperative preparation, and case timing were assessed and compared before and after the QI intervention. Personnel exiting the OR during the MLB was identified as a preintervention issue, with the surgical technologist, circulator, or surgeon exiting the room in 55% of cases (n = 22). The surgical technologist and circulator left the room to retrieve equipment in 40% of cases (n = 16), which indicated the need for increased preoperative preparation to improve case timing and operative flow. The QI interventions implemented to address these concerns included education regarding break timing, improvements in communication, and improvements in ordering and preparation of equipment. After the QI intervention, the surgical technologist exiting rate decreased from 20% (n = 8) to 8% (n = 5), and the circulator exiting rate decreased from 38% (n = 15) to 27% (n = 17). In addition, the rate of surgeon exiting decreased significantly (from 25% [n = 10 of 40] to 9% [n = 6 of 66]) (P = .03). The surgical technologist and circulating nurse remaining in the room were significantly associated with decreased operating time (1.84-minute decrease for surgical technologist [P = .04] and 1.95-minute decrease for circulating nurse [P = .001]). Gains were made in personnel exiting behavior and case timing after implementation of the QI interventions, potentially leading to decreased risk. This process is easily reproduced and is widely accepted by stakeholders.

This study explores the ability of a culturally sensitive and case-based education intervention, Caregivers Like Me, to improve knowledge and attitudes regarding end-of-life (EOL) resources among Latino caregivers. A multicentered, cross-sectional study of Latino communities from different geographical regions and cultural backgrounds. An educational intervention was administered to family caregivers of Latino elders using a case-based video "telenovela" and pretest-posttest questionnaires. Participants (N = 145) were mostly females (79%) with mean age of 56 ± 15 years. They reported active learning from intervention (91%) and high satisfaction (92%) with educational experience. Both caregiver stress self-awareness and willingness to accept professional help improved significantly from pretest to posttest. A culturally sensitive educational intervention increased Latino caregivers' self-awareness about caregiver stress and the need to consider professional assistance for EOL care. © The Author(s) 2015.

Modified crisis intervention for personality disorder.

PubMed

Rudnick, A

1998-01-01

This study proposes that the goal of crisis intervention for persons with personality disorders should be to return them to their pre-crisis level of functioning, even though this is maladaptive. This is contrasted with standard crisis intervention, which aims to return normal or neurotic persons to their pre-crisis normal or neurotic functioning, usually by means of few and short-term therapeutic encounters. The modification proposed costs more time and resources in persons with personality disorders in crisis and fits the intervention to the personality type. This is illustrated by the case of Eve, a patient in crisis, whose pre-crisis functioning was maladaptive because of a dependent personality disorder. The goal of (modified) crisis intervention in this case was to return the patient to her dependent lifestyle, by means of pharmacotherapy combined with intensive supportive psychotherapy during 3-4 months of partial (day) hospitalization. The special nature of crisis in personality disorders is discussed.

Learning disability combined with hearing impairment (LDHI) is a poor prognostic factor for the language development of hearing impaired children after educational intervention. A typical example of a child with LDHI and effective interventions provided by cochlear implants are presented in this report. A case of congenital cytomegaloviral infection that showed dysgraphia as well as profound deafness was reported and an underlying visual processing problem diagnosed in the present case caused the patient's dysgraphia. The dysgraphia could be circumvented by the use of auditory memory fairly established by a cochlear implant.

[Purpose] The purpose of this study was to evaluate the effect of therapeutic climbing activities on the brain waves and attention of a child with attention deficit hyperactivity disorder. [Subject and Methods] The subject of this case study was a 7 year 6-month old child diagnosed with attention deficit hyperactivity disorder. This study was based on evidence gathered at 3 distinct stages: a pre-intervention period, 10 intervention periods (2 weeks), and one post-intervention period. The intervention involved therapeutic climbing activities wearing a weighted vest over the course of 4 weeks. The clinical outcome measures were electroencephalography and the Star Cancellation Test. [Results] The mean activation of alpha waves was improved by the therapeutic intervention. During the intervention, the mean activation of alpha waves was the highest at the F3 cortical locus and the lowest at the T4 cortical locus. The average Star Cancellation Test scores were 43 at pre-intervention, 50 during the therapeutic intervention, and 52 at post-intervention. The performance time of the Star Cancellation Test was 240.1 seconds at pre-intervention, 90.2 seconds during the therapeutic intervention, and 60.0 seconds at post-intervention. [Conclusion] The results of this study suggest that therapeutic climbing activities performed wearing a weighted vest had positive effects on the brain waves and the attention span of a child with attention deficit hyperactivity disorder.

Improving Parolees' Participation in Drug Treatment and Other Services through Strengths Case Management.

PubMed

Prendergast, Michael; Cartier, Jerome J

2008-01-01

In an effort to increase participation in community aftercare treatment for substance-abusing parolees, an intervention based on a transitional case management (TCM) model that focuses mainly on offenders' strengths has been developed and is under testing. This model consists of completion, by the inmate, of a self-assessment of strengths that informs the development of the continuing care plan, a case conference call shortly before release, and strengths case management for three months post-release to promote retention in substance abuse treatment and support the participant's access to designated services in the community. The post-release component consists of a minimum of one weekly client/case manager meeting (in person or by telephone) for 12 weeks. The intervention is intended to improve the transition process from prison to community at both the individual and systems level. Specifically, the intervention is designed to improve outcomes in parolee admission to, and retention in, community-based substance-abuse treatment, parolee access to other needed services, and recidivism rates during the first year of parole. On the systems level, the intervention is intended to improve the communication and collaboration between criminal justice agencies, community-based treatment organizations, and other social and governmental service providers. The TCM model is being tested in a multisite study through the Criminal Justice Drug Abuse Treatment Studies (CJ-DATS) research cooperative funded by the National Institute of Drug Abuse.

This paper reports on the feasibility and initial efficacy of a culturally sensitive, comprehensive women-centered substance use intervention for women who inject drugs in Georgia in terms of the primary and secondary sex risk outcomes. The hypothesis under examination was that, relative to case management participants, participants in a culturally sensitive, comprehensive women-specific and -centered intervention would, on average, show significant decreases in past-30-day frequency of unprotected sex, unprotected sex at the last sexual encounter, and increases in condom use and safer sex actions. The study was a two-arm randomized trial, in which 173 potentially eligible women were screened, and those 128 women determined to be eligible were assigned at random to either Reinforcement-based Treatment plus Women's Co-Op (RBT + WC) or case management (CM). RBT + WC participants received 12 sessions of a structured intervention with the goal of reducing risky sex and substance use and improving physical and mental health. CM participants received 12 sessions of case management and informational brochures that focused on the same issues on which RBT + WC focused. Participants were assessed at baseline, post-treatment, and 3 months following treatment enrollment. Analyses revealed case management having significantly overall higher Safer Sex action scores than RBT + WC, and a significant decrease over time for past 30-day number of unprotected sex acts. Unprotected sex at the last encounter and Condom Use action scores were nonsignificant. Women who inject drugs in Georgia are engaging in risky sexual practices, and are in need of an intervention that addresses these risky behaviors. Reasons for the failure to find differences between a culturally sensitive, comprehensive women-centered intervention and case management tailored to the needs of women who inject drugs in Georgia may have been the result of inadequate power to detect an effect in a sample whose drug use was not as serious as warranted by the intervention.

Intractable duodenal ulcer caused by transmural migration of gossypiboma into the duodenum - a case report and literature review

PubMed Central

2014-01-01

Background Gossypiboma is a term used to describe a mass that forms around a cotton sponge or abdominal compress accidentally left in a patient during surgery. Transmural migration of an intra-abdominal gossypiboma has been reported to occur in the digestive tract, bladder, vagina and diaphragm. Open surgery is the most common approach in the treatment of gossypiboma. However, gossypibomas can be extracted by endoscopy while migrating into the digestive tract. We report a case of intractable duodenal ulcer caused by transmural migration of gossypiboma successfully treated by duodenorrhaphy. A systemic literature review is provided and a scheme of the therapeutic approach is proposed. Case presentation A 61-year-old Han Chinese man presented with intermittent epigastric pain for the last 10 months. He had undergone laparoscopic cholecystectomy conversion to open cholecystectomy for acute gangrenous cholecystitis 10 months ago at another hospital. Transmural migration of gossypiboma into the duodenum was found. Endoscopic intervention failed to remove the entire gauze, and duodenal ulcer caused by the gauze persisted. Surgical intervention was performed and the gauze was removed successfully. The penetrated ulcer was repaired with duodenorrhaphy. The postoperative period was uneventful. We systematically reviewed the literature on transmural migration of gossypiboma into duodenum and present an overview of published cases. Our PubMed search yielded seven reports of transmural migration of retained surgical sponge into the duodenum. Surgical interventions were necessary in two patients. Conclusion Transmural migration of gossypiboma into the duodenum is a rare surgical complication. The treatment strategies include endoscopic extraction and surgical intervention. Prompt surgical intervention should be considered for emergent conditions such as active bleeding, gastrointestinal obstruction, or intra-abdominal sepsis. For non-emergent conditions, surgical intervention could be considered for intractable cases in which endoscopic extraction failed. PMID:24917191

This paper presents the results of a qualitative study to investigate the perceptions and experiences of health workers involved in a a cluster-randomized controlled trial of a novel intervention to improve health worker malaria case-management in 107 government health facilities in Kenya. The intervention involved sending text-messages about paediatric outpatient malaria case-management accompanied by "motivating" quotes to health workers' mobile phones. Ten malaria messages were developed reflecting recommendations from the Kenyan national guidelines. Two messages were delivered per day for 5 working days and the process was repeated for 26 weeks (May to October 2009). The accompanying quotes were unique to each message. The intervention was delivered to 119 health workers and there were significant improvements in correct artemether-lumefantrine (AL) management both immediately after the intervention (November 2009) and 6 months later (May 2010). In-depth interviews with 24 health workers were undertaken to investigate the possible drivers of this change. The results suggest high acceptance of all components of the intervention, with the active delivery of information in an on the job setting, the ready availability of new and stored text messages and the perception of being kept 'up to date' as important factors influencing practice. Applying the construct of stages of change we infer that in this intervention the SMS messages were operating primarily at the action and maintenance stages of behaviour change achieving their effect by creating an enabling environment and providing a prompt to action for the implementation of case management practices that had already been accepted as the clinical norm by the health workers. Future trials testing the effectiveness of SMS reminders in creating an enabling environment for the establishment of new norms in clinical practice as well as in providing a prompt to action for the implementation of the new case-management guidelines are justified.

In the past few years, healthcare systems have been facing a growing demand related to the high prevalence of chronic diseases. Case management programs have emerged as an integrated care approach for the management of chronic disease. Nevertheless, there is little scientific evidence on the impact of using a case management program for patients with complex multimorbidity regarding hospital resource utilisation. We evaluated an integrated case management intervention set up by community-based care at outpatient clinics with nurse case managers from a telemedicine unit. The hypothesis to be tested was whether improved continuity of care resulting from the integration of community-based and hospital services reduced the use of hospital resources amongst patients with complex multimorbidity. A retrospective cohort study was performed using a sample of 714 adult patients admitted to the program between January 2012 and January 2015. We found a significant decrease in the number of emergency room visits, unplanned hospitalizations, and length of stay, and an expected increase in the home care hospital-based episodes. These results support the hypothesis that case management interventions can reduce the use of unplanned hospital admissions when applied to patients with complex multimorbidity. PMID:28970745

Central venous stenosis and obstruction (CVD) is a serious and prevalent challenge to both resolve the venous hypertension symptoms and maintain the pantency of the ipsilateral hemodialysis access in hemodialysis patients. This study aimed to summarize our experience of the endovascular management of the central venous stenosis or obstruction in hemodialysis patients. Twenty-four haemodialysis cases of central vein stenosis or obstruction with ipsilateral functional vascular access in our hospital between July 2006 and February 2012 were treated by interventional therapy and the data were analyzed retrospectively. Eighteen males and six females with mean age of (66.4 ± 13.8) years and manifesting with arm swelling and venous hypertension were enrolled; 62.5% of them had a history of catheterization. Venography showed stenotic lesion in 10 cases including eight cases of brachiocephalic vein stenosis and two cases of subclavian vein stenosis and 14 cases of obstruction lesions including seven cases of short brachiocephalic obstruction and seven cases of long segment obstruction. Interventional therapy was performed and the technique success rate was 83.3%. Percutaneous transluminal angioplasty (PTA) was performed in nine cases and stent was performed in 11 cases firstly. The symptoms of venous hypertension were resolved after intervention in all the cases. There was no major complication and death perioperatively. During follow-up, reintervention was done, the primary patency rates were (88.9 ± 10.5)%, (64.8 ± 10.5)% and (48.6 ± 18.7)% at 3 months, 6 months and 1 year after treatment in the PTA group; (90.0 ± 9.5)% and (77.1 ± 14.4)% at 6 months and 1 year after treatment in the stent group, respectively. The secondary patency rates were (48.6 ± 18.7)% in the PTA group and (83.3 ± 15.2)% in the stent group 1 year after treatment, respectively. There was no significant difference between the two groups (primary patency, P = 0.20; secondary patency, P = 0.10). The endovascular intervention is a safe and effective method for CVD in short term; enhanced follow-up and repeated interventions are required to maintain patency for long term. The prevention is most important. Avoiding and minimizing the placement of the central venous catheter may be the key point for the prevention.

Interventions aiming to coordinate services for the community-based dementia population vary in components, organisation and implementation. In this review we aimed to investigate the views of stakeholders on the key components of community-based interventions coordinating care in dementia. We searched four databases from inception to June 2015; Medline, The Cochrane Library, EMBASE and PsycINFO, this was aided by a search of four grey literature databases, and backward and forward citation tracking of included papers. Title and abstract screening was followed by a full text screen by two independent reviewers, and quality was assessed using the CASP appraisal tool. We then conducted thematic synthesis on extracted data. A total of seven papers from five independent studies were included in the review, and encompassed the views of over 100 participants from three countries. Through thematic synthesis we identified 32 initial codes that were grouped into 5 second-order themes: (1) case manager had four associated codes and described preferences for the case manager personal and professional attributes, including a sound knowledge in dementia and availability of local services; (2) communication had five associated codes and emphasized the importance stakeholders placed on multichannel communication with service users, as well as between multidisciplinary teams and across organisations; (3) intervention had 11 associated codes which focused primarily on the practicalities of implementation such as the contact type and frequency between case managers and service users, and the importance of case manager training and service evaluation; (4) resources had five associated codes which outlined stakeholder views on the required resources for coordinating interventions and potential overlap with existing resources, as well as arising issues when available resources do not meet those required for successful implementation; and (5) support had seven associated codes that reflect the importance that was placed on the support network around the case manager and the investment of professionals involved directly in care as well as the wider professional network. The synthesis of relevant qualitative studies has shown how various stakeholder groups considered dementia care coordination interventions to be acceptable, useful and appropriate for dementia care, and have clear preferences for components, implementation methods and settings of these interventions. By incorporating stakeholders' perspectives and preferences when planning and developing coordinating interventions we may increase the likelihood of successful implementation and patient benefits.

Despite a call for earlier diagnosis of dementia, the diagnostic yield of case finding and its impact on the mental health of patients and relatives are unclear. This study assessed the effect of a two-component intervention of case finding and subsequent care on these outcomes. In a cluster RCT we assessed whether education of family physicians (FPs; trial stage 1) resulted in more mild cognitive impairment (MCI) and dementia diagnoses among older persons in whom FPs suspected cognitive decline and whether case finding by a practice nurse and the FP (trial stage 2) added to this number of diagnoses. In addition, we assessed mental health effects of case finding and subsequent care (trial stage 2). FPs of 15 primary care practices (PCPs = clusters) judged the cognitive status of all persons ≥ 65 years. The primary outcome, new MCI and dementia diagnoses by FPs after 12 months as indicated on a list, was assessed among all persons in whom FPs suspected cognitive impairment but without a formal diagnosis of dementia. The secondary outcome, mental health of patients and their relatives, was assessed among persons consenting to participate in trial stage 2. Trial stage 1 consisted of either intervention component 1: training FPs to diagnose MCI and dementia, or control: no training. Trial stage 2 consisted of either intervention component 2: case finding of MCI and dementia and care by a trained nurse and the FP, or control: care as usual. Seven PCPs were randomized to the intervention; eight to the control condition. MCI or dementia was diagnosed in 42.3% (138/326) of persons in the intervention, and in 30.5% (98/321) in the control group (estimated difference GEE: 10.8%, OR: 1.51, 95%-CI 0.60-3.76). Among patients and relatives who consented to stage 2 of the trial (n = 145; 25%), there were no differences in mental health between the intervention and control group. We found a non-significant increase in the number of new MCI diagnoses. As we cannot exclude a clinically relevant effect, a larger study is warranted to replicate ours.

Objectives To assess whether screening improves the detection of atrial fibrillation (cluster randomisation) and to compare systematic and opportunistic screening. Design Multicentred cluster randomised controlled trial, with subsidiary trial embedded within the intervention arm. Setting 50 primary care centres in England, with further individual randomisation of patients in the intervention practices. Participants 14 802 patients aged 65 or over in 25 intervention and 25 control practices. Interventions Patients in intervention practices were randomly allocated to systematic screening (invitation for electrocardiography) or opportunistic screening (pulse taking and invitation for electrocardiography if the pulse was irregular). Screening took place over 12 months in each practice from October 2001 to February 2003. No active screening took place in control practices. Main outcome measure Newly identified atrial fibrillation. Results The detection rate of new cases of atrial fibrillation was 1.63% a year in the intervention practices and 1.04% in control practices (difference 0.59%, 95% confidence interval 0.20% to 0.98%). Systematic and opportunistic screening detected similar numbers of new cases (1.62% v 1.64%, difference 0.02%, −0.5% to 0.5%). Conclusion Active screening for atrial fibrillation detects additional cases over current practice. The preferred method of screening in patients aged 65 or over in primary care is opportunistic pulse taking with follow-up electrocardiography.

Introduction This paper presents the cost and cost-effectiveness of the Good School Toolkit (GST), a programme aimed at reducing physical violence perpetrated by school staff to students in Uganda. Methods The effectiveness of the Toolkit was tested with a cluster randomised controlled trial in 42 primary schools in Luwero District, Uganda. A full economic costing evaluation and cost-effectiveness analysis were conducted alongside the trial. Both financial and economic costs were collected retrospectively from the provider’s perspective to estimate total and unit costs. Results The total cost of setting up and running the Toolkit over the 18-month trial period is estimated at US$397 233, excluding process monitor (M&E) activities. The cost to run the intervention is US$7429 per school annually, or US$15 per primary school pupil annually, in the trial intervention schools. It is estimated that the intervention has averted 1620 cases of past-week physical violence during the 18-month implementation period. The total cost per case of violence averted is US$244, and the annual implementation cost is US$96 per case averted during the trial. Conclusions The GST is a cost-effective intervention for reducing violence against pupils in primary schools in Uganda. It compares favourably against other violence reduction interventions in the region. PMID:29707243

Performance improvement (PI) programs are an educational tool used to analyze clinical performance of clinicians. The effect of this tool has not been fully explored in orthopedic and trauma surgery. A needs assessment was conducted in connection with a worldwide webinar on magnetic resonance imaging in spinal injuries to identify the clinical need for an educational intervention. A 3-step PI process was defined and implemented over a 6-month period in 1 hospital department. Opportunities for improvement were identified by applying a 10-item quality checklist to 26 cases. A focused educational intervention was delivered to address the identified gaps, and a set of 22 posteducation cases was compared. The department of radiology and the department of trauma surgery of a level I university hospital participated in this study. A total of 26 cases collected before the educational intervention showed several areas for potential improvement. Important information was not provided by the surgeons in their communication with the radiologist. The educational intervention outlined the data and suggested actions. Comparing the information transfer of the preintervention and postintervention data, there was a significant improvement following the intervention (p = 0.0013). Our PI program was able to demonstrate a significant influence on the behavior and the attitude of surgeons and radiologists. Copyright © 2016 Association of Program Directors in Surgery.

An intervention existing of an evidence-based medicine (EBM) course in combination with case method learning sessions (CMLSs) was designed to enhance the professional performance, self-efficacy and job satisfaction of occupational physicians. A cluster randomized controlled trial was set up and data were collected through questionnaires at baseline (T0), directly after the intervention (T1) and 7 months after baseline (T2). The data of the intervention group [T0 (n = 49), T1 (n = 31), T2 (n = 29)] and control group [T0 (n = 49), T1 (n = 28), T2 (n = 28)] were analysed in mixed model analyses. Mean scores of the perceived value of the CMLS were calculated in the intervention group. The overall effect of the intervention over time comparing the intervention with the control group was statistically significant for professional performance (p < 0.001). Job satisfaction and self-efficacy changes were small and not statistically significant between the groups. The perceived value of the CMLS to gain new insights and to improve the quality of their performance increased with the number of sessions followed. An EBM course in combination with case method learning sessions is perceived as valuable and offers evidence to enhance the professional performance of occupational physicians. However, it does not seem to influence their self-efficacy and job satisfaction.

To establish a detection and intervention strategy in order to reduce the number of non-steroidal anti-inflammatory drug (NSAIDs) users at risk of gastropathy from receiving either inadequate or no gastroprotection. Community Pharmacies in Valencia, Spain. Prospective longitudinal intervention study without control group carried out by 79 Community Pharmacies. Patients over 18 who asked for any systemic NSAID were interviewed according to standard procedure. Pharmacist intervention was carried out when a patient at risk of serious NSAID-induced gastrointestinal complications due to inadequate or no gastric protection was identified. The doctor responsible was informed in order to then be able to assess the need to prescribe gastroprotection or change it if inadequate. In the case of over-the-counter (OTC) drugs, pharmacist intervention mainly involved replacing NSAIDs for safer medications. Firstly, the number of patients who had no prescribed gastroprotection or inadequate gastroprotection was determined. Pharmacist intervention then brought about changes in pharmacotherapy in this situation. Of the 6,965 patients who asked for NSAIDs during the study period, 3,054 (43.9%) presented NSAID gastropathy risk factors. 35.6% of the latter (1,089) were not prescribed gastroprotection or were prescribed inadequate gastroprotection. Pharmacist intervention was carried out in 1,075 of these cases. On 391 occasions such risk situations were reported to doctors, who accepted pharmacist intervention on 309 occasions (79.0%) and then either prescribed gastroprotection (77% of cases); changed it (13.9%); withdrew the NSAID (5.8%) or substituted it (3.2%). 235 Pharmacist interventions took place when dispensing OTC NSAIDs. Our strategy allowed us to identify a large number of patients who asked for NSAIDs in Community Pharmacies and who were at risk of NSAID gastropathy, as they received either inadequate gastroprotection or no gastroprotection whatsoever. Moreover, the pharmacist intervention carried out has reduced the number of these risk situations.

Serous macular detachment (SMD) may accompany optic disc pit (ODP) and cause visual loss if untreated. We want to present different therapeutic approaches and interesting optical coherence tomography (OCT) findings in three consecutive cases. In this case series, two patients with SMD and one patient with partial macular detachment and inferior retinal detachment accompanying ODP were evaluated before and after surgical intervention clinically and by spectral-domain OCT. The patients were 44 (case 1), 22 (case 2) and 24 (case 3) years old. Pars plana vitrectomy (PPV) + silicone oil + laser, PPV + sulfur hexafluoride gas (SF6) + laser and pneumatic retinopexy were applied, respectively. The patients were followed for 18, 15 and 14 months. Preoperative best-corrected visual acuities (BCVAs) were 5/100, 7/10 and counting fingers at 1 m. Vision improved in all cases with resolution of subretinal fluid. Final BCVAs were 3/10, 10/10 and 1/10, respectively. OCT images revealed optic disc anomaly details and changes after surgical intervention, photoreceptor outer segment alterations at the detached area and macular surface changes. Surgical intervention should be tailored individually in cases with SMD. OCT is efficient for in vivo evaluation of this pathological condition and anatomical outcomes of surgery.

Simple Summary Understanding how family dogs aid in aspects of daily living such as quality of life, physical activity and human animal interaction is critical towards better understanding child health. Using questionnaires and direct assessment we aimed to better understand the role of the family dog in an animal assisted adapted physical activity intervention. Findings were positive in respect to all primary outcomes in this case study. Generally, the role of the family dog in an adapted physical activity animal assisted intervention had positive results for child health, when the family dog assisted a child with cerebral palsy in this type of intervention. Abstract Purpose: The aim of this case study was to examine the individual effects of an adapted physical activity, animal-assisted intervention (APA-AAI) with the family dog on motor skills, physical activity, and quality of life of a child with cerebral palsy (CP). Method: This study used an A-B-A single-subject design. The assessment phase (phase A) occurred pre- and post-intervention. This consisted of standardized assessments of motor skills, quality of life questionnaires, physical activity (measured using the GT3X+ accelerometer) and the human-animal bond. The intervention (phase B) lasted 8 weeks and consisted of adapted physical activities performed with the family dog once a week for 60 min in a lab setting. In addition, the participant had at-home daily activities to complete with the family dog. Results: Visual analysis was used to analyze the data. Motor skill performance, physical activity, quality of life and human animal interaction gains were observed in each case. Conclusions: These preliminary results provided initial evidence that the family-dog can play a role in healthy lifestyles through APA-AAI in children with CP. PMID:28448430
