Ichthyosis refers to a group of skin diseases characterized by abnormal keratinization of the epidermis, resulting in dryness, roughness and scale of the skin. A girl with ichthyosis, who presented with skin ulcers and infection of the right dorsal foot, was admitted to our department. An autologous razor-thin skin grafting procedure was performed to repair the skin ulcers after debridement and vacuum sealing drain. After 8 months of follow-up, both the donor and recipient site healed well and there were no newly formed ulcers or infections. Although the skin quality of ichthyosis is poor, the lesion area can still be used as donor or recipient cite.

We report on a child with a generalized skin disorder associated with other minor anomalies. At birth, the child presented as a collodion baby, with patchy erythema, generalized irregular dermal atrophy, alopecia, absent eyelashes and eyebrows, and conjunctival pannus. He also had hypertelorism, prominent nasal root, large mouth, micrognathia, brachydactyly, syndactyly involving all interdigital spaces, and camptodactyly of fingers III-V. The hyperkeratotic membrane thinned progressively, leaving a mottled reticulated skin atrophy, with patchy areas of yellowish hyperpigmentation and papyraceous areas. Hair and nails were dystrophic. Mental development was borderline normal. The histological hallmarks of the skin manifestations combined orthokeratotic hyperkeratosis and marked atrophy of the dermis. The dermal extracellular matrix was immature, and factor XIII-a positive dendrocytes were rare and globular rather than dendritic. We frame as a hypothesis that the disease is due to or associated with a defect in maturation of a subset of dermal dendrocytes during fetal life.

A 58-year-old, postmenopausal, multiparous woman presented with a chief complaint of abnormal vaginal bleeding. Endometrial cytology was evaluated twice, revealing only squamous epithelial cells both times. Degenerated leiomyoma or uterine sarcoma was suspected from imaging findings, and total abdominal hysterectomy and bilateral salpingo-oophorectomy were therefore performed. However, histopathological examination revealed no signs of malignancy, and the patient was diagnosed as having ichthyosis uteri with uterine leiomyoma. No koilocytosis was evident, and immunostaining for p16 was also negative. Ichthyosis uteri is an extremely rare disease of unknown origin in which squamous metaplasia of the endometrium occurs across a wide area. Although regarded as a benign condition, cases have been reported in which the underlying condition was squamous cell carcinoma or endometrial adenocarcinoma. If ichthyosis uteri is present, a comprehensive approach is required, and the possibility of uterine malignancy should be considered. However, there may be no direct association between the malignant lesions and ichthyosis uteri. © 2016 Japan Society of Obstetrics and Gynecology.

CATAPHORETIC CHARGES OF COLLODION PARTICLES AND ANOMALOUS OSMOSIS THROUGH COLLODION MEMBRANES FREE FROM PROTEIN

PubMed Central

Loeb, Jacques

1922-01-01

1. It had been shown in previous papers that when a salt solution is separated from pure water by a collodion membrane, water diffuses through the membrane as if it were positively charged and as if it were attracted by the anion of the salt in solution and repelled by the cation with a force increasing with the valency. In this paper, measurements of the P.D. across the membrane (E) are given, showing that when an electrical effect is added to the purely osmotic effect of the salt solution in the transport of water from the side of pure water to the solution, the latter possesses a considerable negative charge which increases with increasing valency of the anion of the salt and diminishes with increasing valency of the cation. It is also shown that a similar valency effect exists in the diffusion potentials between salt solutions and pure water without the interposition of a membrane. 2. This makes it probable that the driving force for the electrical transport of water from the side of pure water into solution is primarily a diffusion potential. 3. It is shown that the hydrogen ion concentration of the solution affects the transport curves and the diffusion potentials in a similar way. 4. It is shown, however, that the diffusion potential without interposition of the membrane differs in a definite sense from the P.D. across the membrane and that therefore the P.D. across the membrane (E) is a modified diffusion potential. 5. Measurements of the P.D. between collodion particles and aqueous solutions (ε) were made by the method of cataphoresis, which prove that water in contact with collodion particles free from protein practically always assumes a positive charge (except in the presence of salts with trivalent and probably tetravalent cations of a sufficiently high concentration). 6. It is shown that an electrical transport of water from the side of water into the solution is always superposed upon the osmotic transport when the sign of charge of the solution in the potential across the membrane (E) is opposite to that of the water in the P.D. between collodion particle and water (ε); supporting the theoretical deductions made by Bartell. 7. It is shown that the product of the P.D. across the membrane (E) into the cataphoretic P.D. between collodion particles and aqueous solution (ε) accounts in general semiquantitatively for that part of the transport of water into the solution which is due to the electrical forces responsible for anomalous osmosis.

Ichthyosis is a cutaneous disorder characterized by excessive amounts of dry thickened skin surface scales. Ocular manifestations of ichthyosis include cicatricial ectropion, which may cause exposure keratoconjunctivitis and rarely corneal perforation. Topical emollients, anti-inflammatory ointments, and systemic retinoids have been used to control the disease process, while surgical correction with donor graft has been reserved for severe cases involving corneal exposure. The authors report a case of a Caucasian male with lamellar ichthyosis with severe bilateral upper and lower eyelid cicatricial ectropion and corneal ulceration requiring surgical correction. Treatment with apremilast, a novel phosphodiesterase-4 inhibitor, for the treatment of a concomitant plaque psoriasis achieved good control of his skin diseases and minimized the recurrence of eyelid ectropion.

Harlequin ichthyosis (HI) is a severe and rare hereditary congenital skin disorder characterized by excessive dryness, ectropion and eclabion. The association of ichthyosis with systemic sclerosis has been described in only three children. No patient with generalized morphea (GM) associated with harlequin ichthyosis was described. A 4-years and 6-months girl, diagnosed with harlequin ichthyosis based on diffuse cutaneous thickening, scaling, erythema, ectropion and eclabium since the first hours of birth was described. She was treated with acitretin (1.0mg/kg/day) and emollient cream. At 3 years and 9 months, she developed muscle contractures with pain on motion and limitation in elbows and knees, and diffuse sclerodermic plaques on the abdomen, back, suprapubic area and lower limbs. Skin biopsy showed rectified epidermis and mild hyperorthokeratosis, reticular dermis with perivascular and periadnexal infiltrates of lymphocytes and mononuclear cells, and reticular dermis and sweat gland sclerosis surrounded by a dense collagen tissue, compatible with scleroderma. The patient fulfilled the GM subtype criteria. Methotrexate and prednisone were introduced. At 4 years and 3 months, new scleroderma lesions occurred and azathioprine was associated with previous therapy, with no apparent changes after two months. A case of harlequin ichthyosis associated with a GM was reported. The treatment of these two conditions is a challenge and requires a multidisciplinary team. Copyright © 2014 Elsevier Editora Ltda.

Through the story of two families presenting ichthyosis, we report the support and social integration difficulties inherent in these genetic diseases. Family No. 1: a 38-year-old shepherd and his wife of 25 years both had lamellar ichthyosis that had been present continually since childhood. They had had 2 stillborn infants as well as a live newborn that were all presenting lamellar ichthyosis. Family No. 2: a 45-year-old housewife was seen at our consultation with her 3 youngest children aged 8 years, 6 years and 18 months. According to the mother, at birth, all 3 children were covered with a membrane resembling plastic that crackled during movement, and they had red eyes. Examination of the 3 children revealed a clinical picture of lamellar ichthyosis with ectropion, malformed ears and brachydactyly. Although they presented delayed growth and weight development, psychomotor development was normal. There was no consanguinity between the parents. In both families, the visible nature of the dermatosis resulted in discrimination and ostracism. The precarious living conditions of the parents and the high cost of treatment in an African setting resulted in degradation of quality of life with exacerbation of the difficulties of social integration, resulting in a lack of schooling and a bleak future for these children.

Collodion-reinforcement and plasma-cleaning of target foils

NASA Astrophysics Data System (ADS)

Stoner, John O.

2002-03-01

The preparation of evaporated target foils can often be facilitated by use of collodion coatings either on the substrate sides or on the exterior surfaces of the foils. Later, such coatings must usually be removed. Cleaning of a foil is necessary if thin layers of adhesives have crept onto the foil. Removal and/or cleaning can often be done satisfactorily with an oxygen plasma. Apparatus and procedures used for this are described. Foils that were cleaned successfully, and some that were incompatible with the cleaning process are listed.

Short stature with congenital ichthyosis.

PIBIDS syndrome (photosensitivity, ichthyosis, brittle hair, intellectual impairment, decreased fertility and short stature) is a variant of trichothiodystrophy. It is a rare form of autosomal recessive congenital ichthyosis. Short stature is a vital component of PIBIDS syndrome. We present the cases of two siblings in whom we diagnosed PIBIDS syndrome. On evaluation for short stature, they were found to have severe vitamin D deficiency, which on correction led to the patients having considerable gain in stature. With this case, we would also like to propose that vitamin D deficiency could be one of the treatable causes of short stature in PIBIDS syndrome. 2015 BMJ Publishing Group Ltd.

Ichthyosis vulgaris: the filaggrin mutation disease.

PubMed

Thyssen, J P; Godoy-Gijon, E; Elias, P M

2013-06-01

Ichthyosis vulgaris is caused by loss-of-function mutations in the filaggrin gene (FLG) and is characterized clinically by xerosis, scaling, keratosis pilaris, palmar and plantar hyperlinearity, and a strong association with atopic disorders. According to the published studies presented in this review article, FLG mutations are observed in approximately 7·7% of Europeans and 3·0% of Asians, but appear to be infrequent in darker-skinned populations. This clinical review article provides an overview of ichthyosis vulgaris epidemiology, related disorders and pathomechanisms. Not only does ichthyosis vulgaris possess a wide clinical spectrum, recent studies suggest that carriers of FLG mutations may have a generally altered risk of developing common diseases, even beyond atopic disorders. Mechanistic studies have shown increased penetration of allergens and chemicals in filaggrin-deficient skin, and epidemiological studies have found higher levels of hand eczema, irritant contact dermatitis, nickel sensitization and serum vitamin D levels. When relevant, individuals should be informed about an increased risk of developing dermatitis when repeatedly or continuously exposed to nickel or irritants. Moreover, with our current knowledge, individuals with ichthyosis vulgaris should be protected against neonatal exposure to cats to prevent atopic dermatitis and should abstain from smoking to prevent asthma. Finally, they should be advised against excessive exposure to factors that decrease skin barrier functions and increase the risk of atopic dermatitis. © 2013 The Authors.

TARGETED PRINCIPLE COMPONENT ANALYSIS: A NEW MOTION ARTIFACT CORRECTION APPROACH FOR NEAR-INFRARED SPECTROSCOPY

PubMed Central

YÜCEL, MERYEM A.; SELB, JULIETTE; COOPER, ROBERT J.; BOAS, DAVID A.

2014-01-01

As near-infrared spectroscopy (NIRS) broadens its application area to different age and disease groups, motion artifacts in the NIRS signal due to subject movement is becoming an important challenge. Motion artifacts generally produce signal fluctuations that are larger than physiological NIRS signals, thus it is crucial to correct for them before obtaining an estimate of stimulus evoked hemodynamic responses. There are various methods for correction such as principle component analysis (PCA), wavelet-based filtering and spline interpolation. Here, we introduce a new approach to motion artifact correction, targeted principle component analysis (tPCA), which incorporates a PCA filter only on the segments of data identified as motion artifacts. It is expected that this will overcome the issues of filtering desired signals that plagues standard PCA filtering of entire data sets. We compared the new approach with the most effective motion artifact correction algorithms on a set of data acquired simultaneously with a collodion-fixed probe (low motion artifact content) and a standard Velcro probe (high motion artifact content). Our results show that tPCA gives statistically better results in recovering hemodynamic response function (HRF) as compared to wavelet-based filtering and spline interpolation for the Velcro probe. It results in a significant reduction in mean-squared error (MSE) and significant enhancement in Pearson’s correlation coefficient to the true HRF. The collodion-fixed fiber probe with no motion correction performed better than the Velcro probe corrected for motion artifacts in terms of MSE and Pearson’s correlation coefficient. Thus, if the experimental study permits, the use of a collodion-fixed fiber probe may be desirable. If the use of a collodion-fixed probe is not feasible, then we suggest the use of tPCA in the processing of motion artifact contaminated data. PMID:25360181

Ichthyoses are a common group of keratinization disorders. A non-inflammatory generalized persistent skin desquamation is observed. It is characterized by increased cell turnover, thickening of the stratum corneum and functional changes of sebaceous and sweat glands. All of these favor fungal proliferation. Dermatophytes may infect skin, hair and nails causing ringworm or tinea. They have the ability to obtain nutrients from keratinized material. One of its most prevalent genera is Trichophyton rubrum. Although tineas and ichthyoses are quite common, the association of the two entities is rarely reported in the literature. Three cases of ichthyosis associated with widespread infection by T. rubrum are presented. Resistance to several antifungal treatments was responsible for worsening of ichthyosis signs and symptoms.

Ichthyoses are a heterogeneous group of inherited cornification disorders characterized by generalized dry skin, scaling and/or hyperkeratosis. Ichthyosis vulgaris is the most common form of ichthyosis in humans and caused by genetic variants in the FLG gene encoding filaggrin. Filaggrin is a key player in the formation of the stratum corneum, the uppermost layer of the epidermis and therefore crucial for barrier function. During terminal differentiation of keratinocytes, the precursor profilaggrin is cleaved by several proteases into filaggrin monomers and eventually processed into free amino acids contributing to the hydration of the cornified layer. We studied a German Shepherd dog with a novel form of ichthyosis. Comparing the genome sequence of the affected dog with 288 genomes from genetically diverse non-affected dogs we identified a private heterozygous variant in the ASPRV1 gene encoding "aspartic peptidase, retroviral-like 1", which is also known as skin aspartic protease (SASPase). The variant was absent in both parents and therefore due to a de novo mutation event. It was a missense variant, c.1052T>C, affecting a conserved residue close to an autoprocessing cleavage site, p.(Leu351Pro). ASPRV1 encodes a retroviral-like protease involved in profilaggrin-to-filaggrin processing. By immunofluorescence staining we showed that the filaggrin expression pattern was altered in the affected dog. Thus, our findings provide strong evidence that the identified de novo variant is causative for the ichthyosis in the affected dog and that ASPRV1 plays an essential role in skin barrier formation. ASPRV1 is thus a novel candidate gene for unexplained human forms of ichthyoses.

Placental sulfatase deficiency: maternal and fetal expression of steroid sulfatase deficiency and X-linked ichthyosis.

Bradshaw, K D; Carr, B R

1986-07-01

PSD-X-linked ichthyosis are manifestations of a similar disorder of an inborn error of metabolism characterized by a deficiency of steroid sulfatase. The decreased enzyme activity is due to the absence of the expression of enzyme (steroid sulfatase) protein. Affected individuals with this disorder are males (X-linked inheritance) with a frequency of 1/2000 to 1/6000 births. Homozygous females from cosanguineous marriages have been reported with this disorder. The diagnosis is suspected and confirmed by: Low estriol excretion; Negative DHEAS loading test Increased DHEAS in amnionic fluid; Normal DHEAS in cord plasma; Possible delayed or abnormal labor patterns; Decreased sulfatase activity in the placenta, fibroblast, erythrocytes, lymphocytes or leukocytes of affected individuals; Development of ichthyosis in male infants at 2 to 3 months of age.

The term ichthyosis describes a generalized disorder of cornification characterized by scaling and/or hyperkeratosis of different skin regions. Mutations in a broad group of genes related to keratinocyte differentiation and epidermal barrier function have been demonstrated to play a causative role in disease development. Ichthyosis may be classified in syndromic or non-syndromic forms based on the occurrence or absence of extracutaneous signs. In this setting, the diagnosis of ichthyosis is an integrated multistep process requiring a multidisciplinary approach in order to formulate the appropriate diagnostic hypothesis and to address the genetic testing. Due to the complex features of the different ichthyoses and the high number of genes involved we have investigated a group of 64 patients, affected by syndromic and non-syndromic diseases, using Next Generation Sequencing as a new tool for the molecular diagnosis. Using this innovative molecular approach we were able to find pathogenic mutations in 53 out of 64 patients resulting in 82.8 % total detection rate. An interesting result from the analysis of the data is the high rate of novel sequence variations found compared to known mutations and the relevant rate of homozygous mutations. The possibility to analyze a large number of genes associated with various diseases allows to study cases with phenotypes not well-determined, giving the opportunity to make new genotype-phenotype correlation. In some cases there were discrepancies between clinical features and histology or electron microscopy and only molecular analysis allowed to definitively resolve the diagnostic dilemma. The genetic diagnosis of ichthyosis leads to a more accurate and effective genetic counseling, allowing correct evaluation of the risk of recurrence, particularly in families with consanguineous background.

Hyperlipidemia secondary to acitretin therapy for lamellar ichthyosis associated with a NIPAL4 mutation improves on a plant-based diet and relapses on a standard Western diet.

Oral retinoids are commonly prescribed for many dermatological conditions and may induce hyperlipidemia. We document the case of a 35-year-old man taking acitretin for congenital lamellar ichthyosis associated with a homozygous deleterious mutation in NIPAL4 who developed retinoid-induced hyperlipidemia that responded dramatically to a whole-food plant-based (WFPB) diet. On presentation, his diet consisted of chicken, fish, low fat meats and dairy, grains, and some fruits and vegetables. He then adopted a WFPB diet without making changes to his medications. His serum lipid levels dropped and his exercise capacity improved. Five months later, after discontinuing the plant-based diet and returning to his baseline diet, his hyperlipidemia returned and persisted despite adjustments to his medications. After a year and a half, the patient again adopted a plant-based diet and his lipid levels fell sharply again. A WFPB diet helped improve and control serum lipid levels in a patient with retinoid-induced hyperlipidemia. Future interventions should focus on ways to help patients successfully adopt and maintain a WFPB diet, as increased adherence to a healthy lifestyle is associated with greater health benefits.

A patient case highlighting the myriad of cutaneous adverse effects of prolonged use of hydroxyurea.

PubMed

Neill, Brett; Ryser, Ted; Neill, John; Aires, Daniel; Rajpara, Anand

2017-11-15

Hydroxyurea is an antimetabolite primarily used to treat myeloproliferative disorders, and chronic treatment is associated with many cutaneous adverse effects ranging in severity from ichthyosis to aggressive nonmelanoma skin cancer. We report a 67-year-oldman with a history of polycythemia vera who was referred for management of progressively worsening dorsal hand lesions. The patient presented withhyperpigmentation, ichthyosis, plantar keratoderma, dermatomyositis-like eruptions, two squamous cell carcinomas, and actinic keratoses. The adversereactions observed were acknowledged to be related to chronic hydroxyurea use. The patient underwent Mohs excision of the squamous cell carcinomas and thehydroxyurea was promptly discontinued; subsequent cutaneous improvement of the dermatomyositislike lesions ensued. Another clinically suspicious aggressive squamous cell carcinoma was suspected and the patient was referred to the plastic surgery department for complete excision because of the size of the lesion. The patient remains on periodic dermatology follow up. We report a case that exemplifies the cutaneous adverse effects of chronic hydroxyurea therapy. Although many cases improve after drug discontinuation, strict photoprotection and ongoing surveillance are indicated given the recently proposed premalignant potential of dermatomyositis-like eruptions and the aggressive nature of hydroxyurea-induced nonmelanoma skin cancer.

Connexin 26 (GJB2) mutation in an Argentinean patient with keratitis-ichthyosis-deafness (KID) syndrome: a case report.

Keratitis-Ichthyosis-Deafness (KID) syndrome is a rare condition characterized by pre-lingual sensorineural deafness with skin hyperkeratinization. The primary cause of the disease is a loss-of-function mutation in the GJB2 gene. Mutations in Argentinean patients have not been described. We studied a 2 year-old boy with bilateral congenital sensorineural deafness with dry skin over the entire body, hypotrichosis of the scalp, thin and light-blond hair. Analysis of the GJB2 gene nucleotide sequence revealed the substitution of guanine-148 by adenine predicted to result in an Asp50Asn amino acid substitution. This is the first KID report in a patient from Argentina. This de novo mutation proved to be the cause of keratitis-ichthyosis-deafness syndrome (KID-syndrome) in the patient, and has implications in medical genetic practice.

The concept of individual burden, associated with disease, has been introduced recently to determine the "disability" caused by the pathology in the broadest sense of the word (psychological, social, economic, physical). Inherited ichthyosis belong to a large heterogeneous group of Mendelian Disorders of Cornification. Skin symptoms have a major impact on patients' Quality of Life but little is known about the burden of the disease on the families of patients. To develop and validate a specific burden questionnaire for the families of patients affected by ichthyosis. Two steps were required. First, the creation of the questionnaire which followed a strict methodological process involving a multidisciplinary team and families. Secondarily, the validation of the questionnaire, including the assessment of its reliability, external validity, reproducibility and sensitivity, was carried out on a population of patients affected by autosomal recessive congenital ichthyosis. A population of parents of patients affected by ichthyosis was enrolled to answer the new questionnaire in association with the Short Form Q12 questionnaire (SF-12) and a clinical severity score was filled for each patient. Ninety four families were interviewed to construct the verbatim in order to create the questionnaire and a cognitive debriefing was realized. The concept of burden could be structured around five components: "economic", "daily life", "familial and personal relationship", "work", and "psychological impact". As a result, "Family Burden Ichthyosis" (FBI) reproducible questionnaire of 25 items was created.Forty two questionnaires were analyzable for psychometric validation. Reliability (Cronbach's alpha coefficient = 0.89), reflected the good homogeneity of the questionnaire. The correlation between mental dimensions of the SF-12 and the FBI questionnaire was statistically significant which confirmed the external validity. The mean FBI score was 71.7 ± 18.8 and a significant difference in the FBI score was shown between two groups of severity underlining a good sensitivity of the questionnaire. The internal and external validity of the "FBI" questionnaire was confirmed and it is correlated to the severity of ichtyosis. Ichthyoses, and other chronic pathologies, are difficult to assess by clinical or Quality of Life aspects alone as their impact can be multidimensional. "FBI" takes them all into consideration in order to explain every angle of the handicap generated.

Final Report for X-ray Diffraction Sample Preparation Method Development

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ely, T. M.; Meznarich, H. K.; Valero, T.

WRPS-1500790, “X-ray Diffraction Saltcake Sample Preparation Method Development Plan/Procedure,” was originally prepared with the intent of improving the specimen preparation methodology used to generate saltcake specimens suitable for XRD-based solid phase characterization. At the time that this test plan document was originally developed, packed powder in cavity supports with collodion binder was the established XRD specimen preparation method. An alternate specimen preparation method less vulnerable, if not completely invulnerable to preferred orientation effects, was desired as a replacement for the method.

Controlled long-term release of small peptide hormones using a new microporous polypropylene polymer: its application for vasopressin in the Brattleboro rat and potential perinatal use

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kruisbrink, J.; Boer, G.J.

1984-12-01

Based on drug release by microporous hollow fibers and the recent introduction of microporous polymers, a new technique was developed for controlled delivery of peptides. Small-diameter microporous polypropylene tubing, lumen-loaded with microgram quantities of vasopressin, and coated with collodion, releases vasopressin after in vitro immersion slowly (1-100 ng/d) and constantly for months. The mechanism of pseudo-zero-order delivery is based on high adsorption of vasopressin, keeping the void volume concentration of dissolved vasopressin constant, which is consequently a constant driving force of outward diffusion. The collodion coating prevents the entry of proteinaceous compounds which would result in rapid desorption of vasopressin.more » The present delivery module provides a lasting release for other peptides as well (lysine-vasopressin, oxytocin, alpha-melanocyte-stimulating hormone and, to a lesser extent, Met-enkephalin). The microporous polymer-collodion device is biocompatible and, loaded with vasopressin, successfully alleviates the diabetes insipidus of Brattleboro rats deficient for vasopressin. Subcutaneous implantation normalized diuresis for a period of 60 d and constant urine vasopressin excretion is observed. When the commercially available osmotic minipump is too large for implantation, the small size of the present controlled-delivery system allows peptide treatment of young and immature laboratory rats, even if located in utero.« less

2015-01-01

Keratitis-ichthyosis-deafness (KID) syndrome is a rare hereditary cornification disorder resulting from mutations in connexin 26, a protein important for intercellular communication. In addition to the characteristic clinical triad of congenital bilateral sensorineural hearing loss, keratitis, and erythrokeratoderma, affected individuals also suffer from chronic bacterial and fungal infections and have an increased risk of benign and malignant cutaneous tumors. Treatments with antibiotics, antifungals, and systemic retinoids have been reported with variable response. Ocular and skeletal toxicity from prolonged exposure to systemic retinoids is a major concern especially in children. We report a case of a 7-year-old boy with KID syndrome complicated by frequent infections who responded well to acitretin 0.5-1.0 mg/kg/day. The patient had significant improvement of the hyperkeratosis on the scalp, trunk, and extremities within 4 weeks after initiating treatment. The patient has been on treatment for over a year without notable ocular, skeletal, or laboratory side effects. A review of the literature focusing on therapeutic options for KID syndrome and concerns about safety and tolerability is presented. © 2014 Wiley Periodicals, Inc.

A skin permeability barrier is essential for terrestrial animals, and its impairment causes several cutaneous disorders such as ichthyosis and atopic dermatitis. Although acylceramide is an important lipid for the skin permeability barrier, details of its production have yet to be determined, leaving the molecular mechanism of skin permeability barrier formation unclear. Here we identified the cytochrome P450 gene CYP4F22 (cytochrome P450, family 4, subfamily F, polypeptide 22) as the long-sought fatty acid ω-hydroxylase gene required for acylceramide production. CYP4F22 has been identified as one of the autosomal recessive congenital ichthyosis-causative genes. Ichthyosis-mutant proteins exhibited reduced enzyme activity, indicating correlation between activity and pathology. Furthermore, lipid analysis of a patient with ichthyosis showed a drastic decrease in acylceramide production. We determined that CYP4F22 was a type I membrane protein that locates in the endoplasmic reticulum (ER), suggesting that the ω-hydroxylation occurs on the cytoplasmic side of the ER. The preferred substrate of the CYP4F22 was fatty acids with a carbon chain length of 28 or more (≥C28). In conclusion, our findings demonstrate that CYP4F22 is an ultra-long-chain fatty acid ω-hydroxylase responsible for acylceramide production and provide important insights into the molecular mechanisms of skin permeability barrier formation. Furthermore, based on the results obtained here, we proposed a detailed reaction series for acylceramide production. PMID:26056268

Harlequin ichthyosis (HI) is the most severe and frequently lethal form of recessive congenital ichthyosis. Although defects in lipid transport, protein phosphatase activity, and differentiation have been described, the genetic basis underlying the clinical and cellular phenotypes of HI has yet to be determined. By use of single-nucleotide–polymorphism chip technology and homozygosity mapping, a common region of homozygosity was observed in five patients with HI in the chromosomal region 2q35. Sequencing of the ABCA12 gene, which maps within the minimal region defined by homozygosity mapping, revealed disease-associated mutations, including large intragenic deletions and frameshift deletions in 11 of the 12 screened individuals with HI. Since HI epidermis displays abnormal lamellar granule formation, ABCA12 may play a critical role in the formation of lamellar granules and the discharge of lipids into the intercellular spaces, which would explain the epidermal barrier defect seen in this disorder. This finding paves the way for early prenatal diagnosis. In addition, functional studies of ABCA12 will lead to a better understanding of epidermal differentiation and barrier formation.

  Mutations in six genes have been identified in autosomal recessive congenital ichthyosis (ARCI). To date, few studies have analysed the spectrum of these mutations in specific populations. We have studied the characteristics of patients with ARCI in Galicia (NW Spain). Methods  We recruited patients by contacting all dermatology departments of Galicia and the Spanish patient organization for ichthyosis. TGM1, ALOX12B, ALOXE3, NIPAL4 and CYP4F22 were analysed in the patients and their relatives. We identified 23 patients with ARCI and estimated a prevalence of 1 : 122 000. Twenty of the patients were studied. Seventeen of them were clinically categorized as having lamellar ichthyosis (LI) and three as having congenital ichthyosiform erythroderma (CIE). TGM1 and ALOXE3 mutations were identified in 12/16 (75%) probands whereas no ALOX12B, NIPAL4 and CYP4F22 mutations were found. TGM1 mutations were found in 11/13 (85%) of LI probands. ALOXE3 mutations were identified in a single patient with CIE. Remarkably, mutations p.Arg760X, p.Asp408ValfsX21 and c.984+1G>A of TGM1 were present in six, four and two families, accounting for 41%, 23% and 14% of all TGM1 mutant alleles, respectively. The high percentage of patients with the same TGM1 mutations, together with the high number of homozygous probands (64%), indicates the existence of a strong founder effect in our population. © 2011 The Authors.

Porokeratotic eccrine ostial and dermal duct nevus is a rare hamartomatous malformation, histologically characterized by cornoid lamellae overlying dilated eccrine ostia. The nevus most commonly presents in the form of multiple filiform keratotic spines in a linear arrangement, usually on the distal extremities. Porokeratotic eccrine and hair follicle nevus is thought to be a variant of porokeratotic eccrine ostial and dermal duct nevus that additionally involves hair follicle infundibula. We report a case of widespread Porokeratotic eccrine and hair follicle nevus that developed in a 15-year-old woman with keratitis-ichthyosis-deafness syndrome. © 2010 Wiley Periodicals, Inc.

The purpose of this study was to compare the quality of the electroencephalographic (EEG) data obtained with a BraiNet template in a practical use setting, to that obtained with standard 10/20 spaced, technologist-applied, collodion-based disk leads. Pairs of 8-hour blocks of EEG data were prospectively collected from 32 patients with a Glasgow coma score of ≤9 and clinical concern for underlying nonconvulsive status epilepticus over a 6-month period in the Neurocritical Care Unit at the Duke University Medical Center. The studies were initiated with the BraiNet template system applied by critical care nurse practitioners or physicians, followed by standard, collodion leads applied by registered technologists using the 10/20 system of placement. Impedances were measured at the beginning and end of each block recorded and variance in impedance, mean impedance, and the largest differences in impedances found within a given lead set were compared. Physicians experienced in reading EEG performed a masked review of the EEG segments obtained to assess the subjective quality of the recordings obtained with the templates. We found no clinically significant differences in the impedance measures. There was a 3-hour reduction in the time required to initiate EEG recording using the templates (P < 0.001). There was no difference in the overall subjective quality distributions for template-applied versus technologist-applied EEG leads. The templates were also found to be well accepted by the primary users in the intensive care unit. The findings suggest that the EEG data obtained with this approach are comparable with that obtained by registered technologist-applied leads and represents a possible solution to the growing clinical need for continuous EEG recording availability in the critical care setting.

Importance Bathing suit ichthyosis (BSI) is a rare congenital disorder of keratinization characterized by restriction of scale to sites of relatively higher temperature such as the trunk, with cooler areas remaining unaffected. Fewer than 40 cases have been reported in the literature. Bathing suit ichthyosis is caused by recessive, temperature-sensitive mutations in the transglutaminase-1 gene (TGM1). Clear genotype-phenotype correlations have been difficult to establish because several of the same TGM1 mutations have been reported in BSI and other forms of congenital ichthyosis. We identify novel and recurrent mutations in 16 participants with BSI. Objective To expand the genotypic spectrum of BSI, identifying novel TGM1 mutations in patients with BSI, and to use BSI genotypes to draw inferences about the temperature sensitivity of TGM1 mutations. Design, Setting, and Participants A total of 16 participants with BSI from 13 kindreds were identified from 6 academic medical centers. A detailed clinical history was obtained from each participant, including phenotypic presentation at birth and disease course. Each participant underwent targeted sequencing of TGM1. Main Outcomes and Measures Phenotypic and genotypic characteristics in these patients from birth onward. Results Of the 16 participants, 7 were male, and 9 were female (mean age, 12.6 years; range, 1-39 years). We found 1 novel TGM1 indel mutation (Ile469_Cys471delinsMetLeu) and 8 TGM1 missense mutations that to our knowledge have not been previously reported in BSI: 5 have been previously described in non–temperature-sensitive forms of congenital ichthyosis (Arg143Cys, Gly218Ser, Gly278Arg, Arg286Gln, and Ser358Arg), and 3 (Tyr374Cys, Phe495Leu, and Ser772Arg) are novel mutations. Three probands were homozygous for Arg264Trp, Arg286Gln, or Arg315Leu, indicating that these mutations are temperature sensitive. Seven of 10 probands with a compound heterozygous TGM1 genotype had a mutation at either arginine 307 or 315, providing evidence that mutations at these sites are temperature sensitive and highlighting the importance of these residues in the pathogenesis of BSI. Conclusions and Relevance Our findings expand the genotypic spectrum of BSI and the understanding of temperature sensitivity of TGM1 mutations. Increased awareness of temperature-sensitive TGM1 genotypes should aid in genetic counseling and provide insights into the pathophysiology of TGM1 ichthyoses, transglutaminase-1 enzymatic activity, and potential therapeutic approaches.

Fundamental and methodological investigations for the improvement of elemental analysis by inductively coupled plasma mass soectrometry

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ebert, Christopher Hysjulien

This dissertation describes a variety of studies meant to improve the analytical performance of inductively coupled plasma mass spectrometry (ICP-MS) and laser ablation (LA) ICP-MS. The emission behavior of individual droplets and LA generated particles in an ICP is studied using a high-speed, high frame rate digital camera. Phenomena are observed during the ablation of silicate glass that would cause elemental fractionation during analysis by ICP-MS. Preliminary work for ICP torch developments specifically tailored for the improvement of LA sample introduction are presented. An abnormal scarcity of metal-argon polyatomic ions (MAr{sup +}) is observed during ICP-MS analysis. Evidence shows thatmore » MAr{sup +} ions are dissociated by collisions with background gas in a shockwave near the tip of the skimmer cone. Method development towards the improvement of LA-ICP-MS for environmental monitoring is described. A method is developed to trap small particles in a collodion matrix and analyze each particle individually by LA-ICP-MS.« less

Ichthyosis prematurity syndrome with separation of fetal membranes and neonatal asphyxia

PubMed Central

Dereksson, Kristjan; Kjartansson, Sveinn; Hjartardóttir, Hulda; Arngrimsson, Reynir

2012-01-01

Ichthyosis prematurity syndrome (IPS) is a rare inherited skin disorder. Children are born prematurely with thick skin and have been found to develop neonatal asphyxia due to occlusions in the bronchial tree from debris in the amniotic fluid. At 31 weeks of gestation, separation of amniotic and chorionic membranes was identified as well as polyhydramnion. The child was born 2 weeks later, with thickened skin with a granular appearance and required immediate ventilation and intensive care. At 2 years of age, the patient has developed an atopic skin condition with severe itching, recurrent skin infections, food intolerance and periods of wheezing. Prenatal observation of separation of foetal membranes or dense amniotic fluid may be signs of IPS and severe complication immediately after birth. PMID:22927265

IMPORTANCE Secondary infections and impaired desquamation complicate certain inherited ichthyoses, but their cellular basis remains unknown. In healthy human epidermis, the antimicrobial peptides cathelicidin (LL-37) and human β-defensin 2 (HBD2), as well as the desquamatory protease kallikrein-related peptidase 7 (KLK7), are delivered to the stratum corneum (SC) interstices by lamellar body (LB) exocytosis. OBJECTIVE To assess whether abnormalities in the LB secretory system could account for increased risk of infections and impaired desquamation in inherited ichthyoses with known abnormalities in LB assembly (Harlequin ichthyosis [HI]), secretion (epidermolytic ichthyosis [EI]), or postsecretory proteolysis (Netherton syndrome [NS]). DESIGN, SETTING, AND PARTICIPANTS Samples from library material were taken from patients with HI, EI, NS, and other ichthyoses, but with a normal LB secretory system, and in healthy controls and were evaluated by electron microscopy and immunohistochemical analysis from July 1, 2010, through March 31, 2013. MAIN OUTCOME AND MEASURES Changes in LB secretion and in the fate of LB-derived enzymes and antimicrobial peptides in ichthyotic patients vs healthy controls. RESULTS In healthy controls and patients with X-linked ichthyosis, neutral lipid storage disease with ichthyosis, and Gaucher disease, LB secretion is normal, and delivery of LB-derived proteins and LL-37 immunostaining persists high into the SC. In contrast, proteins loaded into nascent LBs and their delivery to the SC interstices decrease markedly in patients with HI, paralleled by reduced immunostaining for LL-37, HBD2, and KLK7 in the SC. In patients with EI, the cytoskeletal abnormality impairs the exocytosis of LB contents and thus results in decreased LL-37, HBD2, and KLK7 secretion, causing substantial entombment of these proteins within the corneocyte cytosol. Finally, in patients with NS, although abundant enzyme proteins loaded in parallel with accelerated LB production, LL-37 disappears, whereas KLK7 levels increase markedly in the SC. CONCLUSIONS AND RELEVANCE Together, these results suggest that diverse abnormalities in the LB secretory system account for the increased risk of secondary infections and impaired desquamation in patients with HI, EI, and NS.

Background Null mutations within the filaggrin gene (FLG) cause ichthyosis vulgaris and are associated with atopic eczema. However, the dermatological features of filaggrin haploinsufficiency have not been clearly defined. Objectives This study investigated the genotype–phenotype association between detailed skin phenotype and FLG genotype data in a population-based cohort of children. Methods Children (n= 792) aged 7–9 years were examined by a dermatologist. Features of ichthyosis vulgaris, atopic eczema and xerosis were recorded and eczema severity graded using the Three Item Severity score. Each child was genotyped for the six most prevalent FLG null mutations (R501X, 2282del4, R2447X, S3247X, 3702delG, 3673delC). Fisher’s exact test was used to compare genotype frequencies in phenotype groups; logistic regression analysis was used to estimate odds ratios and penetrance of the FLG null genotype and a permutation test performed to investigate eczema severity in different genotype groups. Results Ten children in this cohort had ichthyosis vulgaris, of whom five had mild–moderate eczema. The penetrance of FLG null mutations with respect to flexural eczema was 55·6% in individuals with two mutations, 16·3% in individuals with one mutation and 14·2% in wild-type individuals. Summating skin features known to be associated with FLG null mutations (ichthyosis, keratosis pilaris, palmar hyperlinearity and flexural eczema) showed a penetrance of 100% in children with two FLG mutations, 87·8% in children with one FLG mutation and 46·5% in wild-type individuals (P< 0·0001, Fisher exact test). FLG null mutations were associated with more severe eczema (P= 0·0042) but the mean difference was only 1–2 points in severity score. Three distinct patterns of palmar hyperlinearity were observed and these are reported for the first time. Conclusions Filaggrin haploinsufficiency appears to be highly penetrant when all relevant skin features are included in the analysis. FLG null mutations are associated with more severe eczema, but the effect size is small in a population setting. PMID:19681860

Congenital erythroderma is a rare and often life-threatening condition, which has been shown to result from mutations in several genes encoding important components of the epidermal differentiation program. Using whole exome sequencing, we identified in a child with congenital exfoliative erythroderma, hypotrichosis, severe nail dystrophy and failure to thrive, two heterozygous mutations in ABCA12 (c.2956C>T, p.R986W; c.5778+2T>C, p. G1900Mfs*16), a gene known to be associated with two forms of ichthyosis, autosomal recessive congenital ichthyosis, and harlequin ichthyosis. Because the patient displayed an atypical phenotype, including severe hair and nail manifestations, we scrutinized the exome sequencing data for additional potentially deleterious genetic variations in genes of relevance to the cornification process. Two mutations were identified in CAPN12, encoding a member of the calpain proteases: a paternal missense mutation (c.1511C>A; p.P504Q) and a maternal deletion due to activation of a cryptic splice site in exon 9 of the gene (c.1090_1129del; p.Val364Lysfs*11). The calpain 12 protein was found to be expressed in both the epidermis and hair follicle of normal skin, but its expression was dramatically reduced in the patient's skin. The downregulation of capn12 expression in zebrafish was associated with abnormal epidermal morphogenesis. Small interfering RNA knockdown of CAPN12 in three-dimensional human skin models was associated with acanthosis, disorganized epidermal architecture, and downregulation of several differentiation markers, including filaggrin. Accordingly, filaggrin expression was almost absent in the patient skin. Using ex vivo live imaging, small interfering RNA knockdown of calpain 12 in skin from K14-H2B GFP mice led to significant hair follicle catagen transformation compared with controls. In summary, our results indicate that calpain 12 plays an essential role during epidermal ontogenesis and normal hair follicle cycling and that its absence may aggravate the clinical manifestations of ABCA12 mutations.

Background Ichthyoses are clinically characterized by scaling or hyperkeratosis of the skin or both. It can be an isolated condition limited to the skin or appear secondarily with involvement of other cutaneous or systemic abnormalities. Methods The present study investigated clinical and molecular characterization of three consanguineous families (A, B, C) segregating two different forms of autosomal recessive congenital ichthyosis (ARCI). Linkage in three consanguineous families (A, B, C) segregating two different forms of ARCI was searched by typing microsatellite and single nucleotide polymorphism marker analysis. Sequencing of the two genes TGM1 and ALOXE3 was performed by the dideoxy chain termination method. Results Genome-wide linkage analysis established linkage in family A to TGM1 gene on chromosome 14q11 and in families B and C to ALOXE3 gene on chromosome 17p13. Subsequently, sequencing of these genes using samples from affected family members led to the identification of three novel mutations: a missense variant p.Trp455Arg in TGM1 (family A); a nonsense variant p.Arg140* in ALOXE3 (family B); and a complex rearrangement in ALOXE3 (family C). Conclusion The present study further extends the spectrum of mutations in the two genes involved in causing ARCI. Characterizing the clinical spectrum resulting from mutations in the TGM1 and ALOXE3 genes will improve diagnosis and may direct clinical care of the family members. PMID:26578203

Harlequin ichthyosis (HI) was the most severe form of ichthyoses, which leaded to neonatal death in 50% of cases. It was the result of mutations in ABCA12 gene. With the development of ultrasound skills and genetic analysis, HI could be prenatal diagnosed. Here, we reported a case of HI, which was prenatal diagnosed by ultrasound examination and genetic analysis. The fetus was found that severe ectropion, eclabium, flattened nose, and rudimentary ears by ultrasound at 20 weeks gestation. A molecular genetic analysis was performed and revealed two mutations in the ABCA12 gene. One of two mutations were not reported in the past. The fetus was terminated. HI was associated with the poor prognosis of HI neonates. Prenatal ultrasound and genetic analysis were important for prenatal diagnosis of HI and were helpful to give sufficient prenatal counsels for the family with HI baby. Copyright © 2018.

Inability of keratinocytes lacking their specific transglutaminase to form cross-linked envelopes: absence of envelopes as a simple diagnostic test for lamellar ichthyosis.

PubMed

Jeon, S; Djian, P; Green, H

1998-01-20

Epidermal keratinocytes, late in their terminal differentiation, form cross-linked envelopes resistant to ionic detergent and reducing agent. Because the cross-linking process is catalyzed by the keratinocyte transglutaminase, the absence of active transglutaminase should result in failure of the keratinocyte to form a cross-linked envelope. Three keratinocyte strains bearing mutations in the keratinocyte transglutaminase were examined: two contained no detectable transglutaminase mRNA and none contained active enzyme. All three were unable to form cross-linked envelopes, either spontaneously in stratified cultures or upon induction with Ca2+. Although stratum corneum of normal humans and scales from patients with different ichthyotic diseases contain cross-linked envelopes, those from patients with transglutaminase-negative lamellar ichthyosis do not. Therefore, the disease due to the absence of transglutaminase may be readily distinguished from other ichthyotic disease by a simple test for cross-linked envelopes.

Bathing suit ichthyosis (BSI) is a striking and unique clinical form of autosomal recessive congenital ichthyosis characterized by pronounced scaling on the bathing suit areas but sparing of the extremities and the central face. Here we report on a series of 10 BSI patients. Our genetic, ultrastructural and biochemical investigations show that BSI is caused by transglutaminase-1 (TGase-1) deficiency. Altogether, we identified 13 mutations in TGM1-among them seven novel missense mutations and one novel nonsense mutation. Structural modeling for the Tyr276Asn mutation reveals that the residue is buried in the hydrophobic interior of the enzyme and that the hydroxyl side chain of Tyr276 is exposed to solvent in a cavity of the enzyme. Cryosections of healthy skin areas demonstrated an almost normal TGase activity, in contrast to the affected BSI skin, which only showed a cytoplasmic and clearly reduced TGase-1 activity. The distribution of TGase-1 substrates in the epidermis of affected skin corresponded to the situation in TGase-1 deficiency. Interestingly, the expression of TGase-3 and cathepsin D was reduced. Digital thermography validated a striking correlation between warmer body areas and presence of scaling in patients suggesting a decisive influence of the skin temperature. In situ TGase testing in skin of BSI patients demonstrated a marked decrease of enzyme activity when the temperature was increased from 25 to 37 degrees C. We conclude that BSI is caused by TGase-1 deficiency and suggest that it is a temperature-sensitive phenotype.

Arthrogryposis-renal dysfunction-cholestasis (ARC) syndrome: from molecular genetics to clinical features.

PubMed

Zhou, Yaoyao; Zhang, Junfeng

2014-09-20

Arthrogryposis-renal dysfunction-cholestasis (ARC) syndrome is a rare but fatal autosomal recessive multisystem disorder caused by mutations in the VPS33B or VIPAR gene. The classical presentation of ARC includes congenital joint contractures, renal tubular dysfunction, and cholestasis. Additional features include ichthyosis, central nervous system malformation, platelet anomalies, and severe failure to thrive. Diagnosis of ARC syndrome relies on clinical features, organ biopsy, and mutational analysis. However, no specific treatment currently exists for this syndrome. This is an overview of the latest knowledge regarding the genetic features and clinical manifestations of ARC syndrome. Greater awareness and understanding of this syndrome should allow more timely intervention with potential for improving long-term outcome.

In this paper, the relation between psychological factors and psychiatric disorders in patients with skin diseases is discussed. On the one hand psychological factors (stress, negative emotions) can influence the generation and aggravation of skin disorders (urticaria, atopic dermatitis, vitiligo), on the other hand psychological disorders can result in some skin diseases (psoriasis, atopic dermatitis). In the majority of cases the quality of life is poorly estimated by patients with skin problems. Psychodermatology is divided into three categories according to the relationship between skin diseases and mental disorders: 1) psychophysiologic disorders caused by skin diseases triggering different emotional states (stress), but not directly combined with mental disorders (psoriasis, eczema); 2) primary psychiatric disorders responsible for self-induced skin disorders (trichotillomania); and 3) secondary psychiatric disorders caused by disfiguring skin (ichthyosis, acne conglobata, vitiligo), which can lead to states of fear, depression or suicidal thoughts.

To compare the topographic and biomechanical properties of corneas in eyes of patients with ichthyosis vulgaris (IV) and eyes of healthy individuals. Thirty healthy individuals (control group) and 30 patients with IV (study group) were enrolled in this prospective study. Topographic measurements, including keratometry values, irregularity, and surface asymmetry index in the right eye of each participant were obtained using Scheimpflug camera with a Placido disc topographer (Sirius). Corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc) and Goldman-related intraocular pressure (IOPg) were measured using the Reichert Ocular Response Analyzer (ORA). Central corneal thickness (CCT) was also measured with ultrasonic pachymetry and the Sirius corneal topography system. Topographic parameters were not significantly different between both groups (p>0.05). Although mean CH was not significantly different between the groups, the CRF was significantly lower in patients with IV (p=0.249 and p=0.005, respectively). The CCT was significantly lower in patients with IV compared to healthy controls (p<0.001). The IOPg and IOPcc were significantly lower in the patients with ichthyosis than in healthy controls (p=0.001 and p=0.004, respectively). The study demonstrated that while the eyes of patients with IV had corneal topographic findings and corneal hysteresis similar to those of healthy controls, some of corneal biomechanical properties such CRF and CCT and IOP values such as IOPg and IOPcc were significantly lower in patients with IV. These results should be taken into account when planning a corneal refractive surgery and glaucoma screening for patients with IV. Copyright © 2012 British Contact Lens Association.

Ichthyoses are a group of various different types of hereditary disorders affecting skin cornification. They are characterized by hyperkeratoses of different severity levels and are associated with a dry and scaling skin. Genome-wide association analysis of nine affected and 13 unaffected Great Danes revealed a genome-wide significant peak on chromosome 9 at 57-58 Mb in the region of SLC27A4. Sequence analysis of genomic DNA of SLC27A4 revealed the non-synonymous SNV SLC27A4:g.8684G>A in perfect association with ichthyosis-affection in Great Danes. The mutant transcript of SLC27A4 showed an in-frame loss of 54 base pairs in exon 8 probably induced by a new splice acceptor site motif created by the mutated A- allele of the SNV. Genotyping 413 controls from 35 different breeds of dogs and seven wolves revealed that this mutation could not be found in other populations except in Great Danes. Affected dogs revealed high amounts of mutant transcript but only low levels of the wild type transcript. Targeted analyses of SLC27A4 protein from skin tissues of three affected and two unaffected Great Danes indicated a markedly reduced or not detectable wild type and truncated protein levels in affected dogs but a high expression of wild type SLC27A4 protein in unaffected controls. Our data provide evidence of a new splice acceptor site creating SNV that results in a reduction or loss of intact SLC27A4 protein and probably explains the severe skin phenotype in Great Danes. Genetic testing will allow selective breeding to prevent ichthyosis-affected puppies in the future.

Thirty-two confirmed cases of non -Hodgkin's lymphoma (NHL) were examined for cutaneous manifestations for a period of 2 years from November 1998 in KMC Hospital Attavar, Mangalore. Cutaneous manifestations in the study group were compared to a control group of 32 patients. Specific infiltrates were present in all (5/5) CTCL patients and one out of twenty-seven patients with low grade NHL. Morphologically they presented as papules, plaques, nodules and erythroderma. Infective conditions seen in the study group were superficial fungal (7/32) and viral infections (2/ 32). Non-infective conditions were acquired ichthyosis (10/32), generalised pruritus (5/32), insect bite reaction (1/32) and drug eruption (1/32). When compared to control patients only acquired ichthyosis and generalised pruritus were found to be statistically significant. The study group also showed changes due to chemotherapy like diffuse alopecia (24/29), bluish pigmentation of proximal part of nail (4/29), localised pigmentation of palms and soles (1 /29), diffuse pigmentation at injection site (1 /29), pigmentation at scar site (1 /29) and stomatitis (4/29).

A novel recessive mutation in the gene ELOVL4 causes a neuro-ichthyotic disorder with variable expressivity

PubMed Central

2014-01-01

Background A rare neuro-ichthyotic disorder characterized by ichthyosis, spastic quadriplegia and intellectual disability and caused by recessive mutations in ELOVL4, encoding elongase-4 protein has recently been described. The objective of the study was to search for sequence variants in the gene ELOVL4 in three affected individuals of a consanguineous Pakistani family exhibiting features of neuro-ichthyotic disorder. Methods Linkage in the family was searched by genotyping microsatellite markers linked to the gene ELOVL4, mapped at chromosome 6p14.1. Exons and splice junction sites of the gene ELOVL4 were polymerase chain reaction amplified and sequenced in an automated DNA sequencer. Results DNA sequence analysis revealed a novel homozygous nonsense mutation (c.78C > G; p.Tyr26*). Conclusions Our report further confirms the recently described ELOVL4-related neuro-ichthyosis and shows that the neurological phenotype can be absent in some individuals. PMID:24571530

To identify mutation of GJB2 gene and provide genetic counseling for a family affected with keratitis-ichthyosis-deafness (KID) syndrome. Genomic DNA was extracted from peripheral blood samples with a standard phenol-chloroform method. PCR and Sanger sequencing were used to analyze potential mutation in the proband. Suspected mutation was verified with a PCR-high-resolution melting (PCR-HRM) method. T-clone sequencing was applied to determine the parental origin of the mutation. A heterozygous mutation, c.148G>A (p.Asp50Asn), which is located in the exon 1 of the GJB2 gene, was found in the proband. The results was confirmed by HRM analysis. Cloning sequencing suggested that the mutation was derived from the father's germline. The hot-spot mutation c.148G>A (p.Asp50Asn) in the GJB2 gene probably underlies the KID syndrome in this Chinese family. A PCR-HRM method has been established to rapidly detect common mutations associated with this disease.

Linkage of autosomal recessive lamellar ichthyosis to chromosome 14q

DOE Office of Scientific and Technical Information (OSTI.GOV)

Russell, L.J.; Compton, J.G.; Bale, S.J.

The authors have mapped the locus for lamellar ichthyosis (LI), an autosomal recessive skin disease characterized by abnormal cornification of the epidermis. Analysis using both inbred and outbred families manifesting severe LI showed complete linkage to several markers within a 9.3-cM region on chromosome 14q11. Affected individuals in inbred families were also found to have striking homozygosity for markers in this region. Linkage-based genetic counseling and prenatal diagnosis is now available for informative at-risk families. Several transcribed genes have been mapped to the chromosome 14 region containing the LI gene. The transglutaminase 1 gene (TGM1), which encodes one of themore » enzymes responsible for cross-linking epidermal proteins during formation of the stratum corneum, maps to this interval. The TGM1 locus was completely linked to LI (Z = 9.11), suggesting that TGM1 is a good candidate for further investigation of this disorder. The genes for four serine proteases also map to this region but are expressed only in hematopoietic or mast cells, making them less likely candidates.« less

Keratitis-Ichthyosis-Deafness (KID) syndrome (OMIM 148210) is a congenital ectodermal defect that consists of an atypical ichthyosiform erythroderma associated with congenital sensorineural deafness. KID appears to be genetically heterogeneous and most cases are caused by GJB2 mutations. Mutations in African patients have been rarely described. We report on two unrelated Cameroonian individuals affected with sporadic KID, presenting with the classic phenotypic triad. The two patients were heterozygous for the most frequent p.Asp50Asn mutation. This first report in patients from sub-Saharan African origin supports the hypothesis that the occurrence of KID due to p.Asp50Asn mutation in GJB2 seems not to be population specific. Our finding has implication in medical genetic practice, specifically in the molecular diagnosis of KID in Africans. These cases also reveal and emphasize the urgent need to develop appropriate policies to care for patients with rare/orphan diseases in Sub-Saharan Africa, as many of these cases become more and more recognizable.

Alopecia-contractures-dwarfism mental retardation syndrome (ACD syndrome; OMIM 203550) is a very rare genetic disorder with distinct features. To our knowledge, there have been four cases documented to date. In addition, another three patients, previously described as having IFAP syndrome (OMIM %308205), may also have ACD syndrome. We report on one patient with short stature, total alopecia, ichthyosis, photophobia, seizures, ectrodactyly, vertebral anomalies, scoliosis, multiple contractures, mental retardation, and striking facial and other features (e.g. microdolichocephaly, missing eyebrows and eyelashes, long nose, large ears) consistent with ACD syndrome. Results of laboratory testing in the literature case reports were normal, although in none of them, array-CGH (microarray-based comparative genomic hybridization) analysis was performed. In conclusion, the combination of specific features, including total alopecia, ichthyosis, mental retardation, and skeletal anomalies are suggestive of ACD syndrome. We propose that children with this syndrome undergo a certain social pediatric protocol including EEG diagnostics, ophthalmological investigation, psychological testing, management of dermatologic and orthopedic problems, and genetic counseling.

The aim of this study was to describe a case of severe keratitis-ichthyosis-deafness (KID) syndrome with ocular surface squamous neoplasia. The affected patient underwent complete ocular and systemic examinations. The molecular studies included polymerase chain reaction amplification and automated DNA sequencing of the complete gap junction beta-2 (GJB2) gene coding sequence. A 30-year-old man presented with generalized erythro-hyperkeratosis and deafness and complaints of decreased visual acuity, tearing, and photophobia. Ophthalmic examination showed corneal erosion, vascularization, and a gray gelatinous lesion partially covering the right cornea, suggestive of squamous neoplasia. The clinical features were characteristic of KID syndrome. This diagnosis was confirmed with a DNA analysis showing the pathogenic variant p.D50N in the GJB2 gene. Presumed squamous neoplasia was treated with topical interferon α2b. KID syndrome is a very rare disease that has been reported with an incremental incidence of squamous cell carcinoma of the mucous membranes and skin (12%-15%). Here, we presented a case of severe systemic KID syndrome with ocular surface squamous neoplasia.

SERPINS comprise a large and functionally diverse family of serine protease inhibitors. Here, we report three unrelated families with loss-of-function mutations in SERPINB8 in association with an autosomal-recessive form of exfoliative ichthyosis. Whole-exome sequencing of affected individuals from a consanguineous Tunisian family and a large Israeli family revealed a homozygous frameshift mutation, c.947delA (p.Lys316Serfs(∗)90), and a nonsense mutation, c.850C>T (p.Arg284(∗)), respectively. These two mutations are located in the last exon of SERPINB8 and, hence, would not be expected to lead to nonsense-mediated decay of the mRNA; nonetheless, both mutations are predicted to lead to loss of the reactive site loop of SERPINB8, which is crucial for forming the SERPINB8-protease complex. Using Sanger sequencing, a homozygous missense mutation, c.2T>C (p.Met1?), predicted to result in an N-terminal truncated protein, was identified in an additional family from UAE. Histological analysis of a skin biopsy from an individual homozygous for the variant p.Arg284(∗) showed disadhesion of keratinocytes in the lower epidermal layers plus decreased SERPINB8 levels compared to control. In vitro studies utilizing siRNA-mediated knockdown of SERPINB8 in keratinocytes demonstrated that in the absence of the protein, there is a cell-cell adhesion defect, particularly when cells are subjected to mechanical stress. In addition, immunoblotting and immunostaining revealed an upregulation of desmosomal proteins. In conclusion, we report mutations in SERPINB8 that are associated with exfoliative ichthyosis and provide evidence that SERPINB8 contributes to the mechanical stability of intercellular adhesions in the epidermis.

Biofeedback can improve cutaneous problems that have an autonomic nervous system component. Examples include biofeedback of galvanic skin resistance (GSR) for hyperhidrosis and biofeedback of skin temperature for Raynaud's disease. Hypnosis may enhance the effects obtained by biofeedback. Cognitive-behavioral methods may resolve dysfunctional thought patterns (cognitive) or actions (behavioral) that damage the skin or interfere with dermatologic therapy. Responsive diseases include acne excoriée, atopic dermatitis, factitious cheilitis, hyperhidrosis, lichen simplex chronicus, needle phobia, neurodermatitis, onychotillomania, prurigo nodularis, trichotillomania, and urticaria. Hypnosis can facilitate aversive therapy and enhance desensitization and other cognitive-behavioral methods. Hypnosis may improve or resolve numerous dermatoses. Examples include acne excoriée, alopecia areata, atopic dermatitis, congenital ichthyosiform erythroderma, dyshidrotic dermatitis, erythromelalgia, furuncles, glossodynia, herpes simplex, hyperhidrosis, ichthyosis vulgaris, lichen planus, neurodermatitis, nummular dermatitis, postherpetic neuralgia, pruritus, psoriasis, rosacea, trichotillomania, urticaria, verruca vulgaris, and vitiligo. Hypnosis can also reduce the anxiety and pain associated with dermatologic procedures.

Keratitis-ichthyosis-deafness (KID) syndrome is a rare ectodermal dysplasia characterized by generalized erythrokeratotic plaques, sensorineural hearing loss, and vascularizing keratitis. Cutaneous changes and hearing loss typically present in early childhood, whereas ocular symptoms present later. Mutations in the connexin (Cx) 26 gene, GJB2, are now established to underlie many of the affected cases, with the majority of patients harboring the p.D50N mutation. A rare patient demonstrating features of incomplete KID syndrome associated with an uncommon Cx26 gene mutation is described. The patient presented late in adolescence with partial features of KID syndrome. There was limited cutaneous involvement and the rare association of cystic acne. Both hearing impairment and ophthalmic involvement were mild in severity. Genetic mutation analysis revealed a previously described, rare mutation in GJB2, resulting in a glycine to arginine change at codon 12 (p.G12R). This report describes a patient exhibiting characteristics suggestive of a late-onset, incomplete form of KID syndrome with the GJB2 mutation (p.G12R). The p.G12R mutation has only been described in one other patient with KID syndrome, whose clinical presentation was not characterized.

A consanguineous family from Pakistan was ascertained to have a novel deafness-dystonia syndrome with motor regression, ichthyosis-like features and signs of sensory neuropathy. By applying a combined strategy of linkage analysis and whole-exome sequencing in the presented family, a homozygous nonsense mutation, c.4G>T (p.Glu2*), in FITM2 was identified. FITM2 and its paralog FITM1 constitute an evolutionary conserved protein family involved in partitioning of triglycerides into cellular lipid droplets. Despite the role of FITM2 in neutral lipid storage and metabolism, no indications for lipodystrophy were observed in the affected individuals. In order to obtain independent evidence for the involvement of FITM2 in the human pathology, downregulation of the single Fitm ortholog, CG10671, in Drosophila melanogaster was pursued using RNA interference. Characteristics of the syndrome, including progressive locomotor impairment, hearing loss and disturbed sensory functions, were recapitulated in Drosophila, which supports the causative nature of the FITM2 mutation. Mutation-based genetic counseling can now be provided to the family and insight is obtained into the potential impact of genetic variation in FITM2. © 2017.

Very-long-chain fatty acids (VLCFAs) play important roles in membrane structure and cellular signaling, and their contribution to human health is increasingly recognized. Fatty acid elongases catalyze the first and rate-limiting step in VLCFA synthesis. Heterozygous mutations in ELOVL4, the gene encoding one of the elongases, are known to cause macular degeneration in humans and retinal abnormalities in mice. However, biallelic ELOVL4 mutations have not been observed in humans, and murine models with homozygous mutations die within hours of birth as a result of a defective epidermal water barrier. Here, we report on two human individuals with recessive ELOVL4 mutations revealed by a combination of autozygome analysis and exome sequencing. These individuals exhibit clinical features of ichthyosis, seizures, mental retardation, and spasticity-a constellation that resembles Sjögren-Larsson syndrome (SLS) but presents a more severe neurologic phenotype. Our findings identify recessive mutations in ELOVL4 as the cause of a neuro-ichthyotic disease and emphasize the importance of VLCFA synthesis in brain and cutaneous development.

These findings are similar to those in a previously described case, and consistent with dysmyelination. Spectroscopy showed increased myoinositol and decreased choline.

Preventing Cauliflower Ear With a Modified Tie-Through Technique.

Dimeff, R J; Hough, D O

1989-03-01

In brief: Hematoma following trauma to the external ear is a common problem among wrestlers and boxers. If the hematoma is not treated promptly, infection, fibrosis, scarring, and calcification may develop, leading to the gross deformity known as cauliflower ear or wrestler's ear. Evacuation of the hematoma followed by compression of the auricle is commonly regarded as the treatment of choice. However, fluid frequently reaccumulates after this procedure. The authors describe a tie-through suture technique in which a collodion packing is secured to the auricle with two buttons. Multiple treatments for fluid reaccumulation are rarely necessary when this technique is used.

Hyperkeratosis of the nipple and areola is a rare condition. We report two cases of hyperkeratosis of the nipple and areola occurring in men with no underlying endocrinopathy or synthetic estrogenic drug therapy. Both patients demonstrated prompt resolution of the hyperkeratosis of the nipples with a keratolytic gel. Because our cases were not associated with ichthyosis or epidermal nevus, they best fit into the category of nevoid hyperkeratosis of the nipples.

FLG mutations in ichthyosis vulgaris and atopic eczema: spectrum of mutations and population genetics.

PubMed

Akiyama, M

2010-03-01

Filaggrin is a key protein involved in skin barrier function. Mutations in the gene encoding filaggrin (FLG) have been identified as the cause of ichthyosis vulgaris and have been shown to be major predisposing factors for atopic eczema (AE), initially in European populations. Subsequently, FLG mutations were identified in Japanese, Chinese, Taiwanese and Korean populations. It was demonstrated that FLG mutations are closely associated with AE in the Japanese population. Notably, the same FLG mutations identified in the European population were rarely found in Asians. These results exemplify differences in filaggrin population genetics between Europe and Asia. For mutation screening, background information needs to be obtained on prevalent FLG mutations for each geographical population. It is therefore important to establish the global population genetics maps for FLG mutations. Mutations at any site within FLG, even mutations in C-terminal imperfect filaggrin repeats, cause significant reductions in amounts of profilaggrin/filaggrin peptide in patient epidermis as the C-terminal region is essential for proper processing of profilaggrin into filaggrin. Thus, no genotype-phenotype correlation has been observed in patients with FLG mutations. A restoration of the barrier function seems a feasible and promising strategy for treatment and prevention in individuals with filaggrin deficiency.

Keratitis-ichthyosis-deafness (KID) syndrome is an ectodermal dysplasia caused by dominant mutations of connexin26 (Cx26). Loss of Cx26 function causes non-syndromic sensorineural deafness, without consequence in the epidermis. Functional analyses have revealed that a majority of KID-causing mutations confer a novel expansion of hemichannel activity, mediated by connexin channels in a non-junctional configuration. Inappropriate Cx26 hemichannel opening is hypothesized to compromise keratinocyte integrity and epidermal homeostasis. Pharmacological modulators of Cx26 are needed to assess the pathomechanistic involvement of hemichannels in the development of hyperkeratosis in KID syndrome. We have used electrophysiological assays to evaluate small molecule analogs of quinine for suppressive effects on aberrant hemichannel currents elicited by KID mutations. Here, we show that mefloquine inhibits several mutant hemichannel forms implicated in KID syndrome when expressed in Xenopus laevis oocytes (IC50≈16µM), using an extracellular divalent cation, zinc (Zn++), as a non-specific positive control for comparison (IC50≈3µM). Furthermore, we used freshly isolated transgenic keratinocytes to show that micromolar concentrations of mefloquine attenuated increased macroscopic membrane currents in primary mouse keratinocytes expressing human Cx26-G45E, a mutation causing a lethal form of KID syndrome.

Mutations in the human gene encoding connexin 26 (Cx26 or GJB2) cause either nonsyndromic deafness or syndromic deafness associated with skin diseases. That distinct clinical disorders can be caused by different mutations within the same gene suggests that different channel activities influence the ear and skin. Here we use three different expression systems to examine the functional characteristics of two Cx26 mutations causing either mild (Cx26-D50A) or lethal (Cx26-A88V) keratitis-ichthyosis-deafness (KID) syndrome. In either cRNA-injected Xenopus oocytes, transfected HeLa cells, or transfected primary human keratinocytes, we show that both Cx26-D50A and Cx26-A88V form active hemichannels that significantly increase membrane current flow compared with wild-type Cx26. This increased membrane current accelerated cell death in low extracellular calcium solutions and was not due to increased mutant protein expression. Elevated mutant hemichannel currents could be blocked by increased extracellular calcium concentration. These results show that these two mutations exhibit a shared gain of functional activity and support the hypothesis that increased hemichannel activity is a common feature of human Cx26 mutations responsible for KID syndrome.

Epicuticular wax on cherry laurel (Prunus laurocerasus) leaves does not constitute the cuticular transpiration barrier.

PubMed

Zeisler, Viktoria; Schreiber, Lukas

2016-01-01

Epicuticular wax of cherry laurel does not contribute to the formation of the cuticular transpiration barrier, which must be established by intracuticular wax. Barrier properties of cuticles are established by cuticular wax deposited on the outer surface of the cuticle (epicuticular wax) and in the cutin polymer (intracuticular wax). It is still an open question to what extent epi- and/or intracuticular waxes contribute to the formation of the transpiration barrier. Epicuticular wax was mechanically removed from the surfaces of isolated cuticles and intact leaf disks of cherry laurel (Prunus laurocerasus L.) by stripping with different polymers (collodion, cellulose acetate and gum arabic). Scanning electron microscopy showed that two consecutive treatments with all three polymers were sufficient to completely remove epicuticular wax since wax platelets disappeared and cuticle surfaces appeared smooth. Waxes in consecutive polymer strips and wax remaining in the cuticle after treatment with the polymers were determined by gas chromatography. This confirmed that two treatments of the polymers were sufficient for selectively removing epicuticular wax. Water permeability of isolated cuticles and cuticles covering intact leaf disks was measured using (3)H-labelled water before and after selectively removing epicuticular wax. Cellulose acetate and its solvent acetone led to a significant increase of cuticular permeability, indicating that the organic solvent acetone affected the cuticular transpiration barrier. However, permeability did not change after two subsequent treatments with collodion and gum arabic or after treatment with the corresponding solvents (diethyl ether:ethanol or water). Thus, in the case of P. laurocerasus the epicuticular wax does not significantly contribute to the formation of the cuticular transpiration barrier, which evidently must be established by the intracuticular wax.

Two dizygous twin sisters with the Sjögren-Larsson syndrome are described. There was parental consanguinity, and the condition is inherited as an autosomal recessive. The main features are mental retardation, spastic diplegia and ichthyosis. Sensory defects of gums and abnormal facial movements were found in the twins, these being recognised features of the syndrome. It is suggested that the condition may be due to an abnormality of the neural crest.

A minority of patients with nonsyndromic autosomal recessive congenital ichthyosis (ARCI) display mutations in NIPAL4 (ICHTHYIN). This protein plays a role in epidermal lipid metabolism, although the mechanism is unknown. The study describes a moderate form of ARCI in an extended pedigree of American Bulldogs that is linked to the gene encoding ichthyin. The gross phenotype was manifest as a disheveled pelage shortly after birth, generalized scaling, and adherent brown scale with erythema of the abdominal skin. Pedigree analysis indicated an autosomal recessive mode of inheritance. Ultrastructurally, the epidermis showed discontinuous lipid bilayers, unprocessed lipid within corneocytes, and abnormal lamellar bodies. Linkage analysis, performed by choosing simple sequence repeat markers and single-nucleotide polymorphisms near genes known to cause ACRI, revealed an association with NIPAL4. NIPAL4 was identified and sequenced using standard methods. No mutation was identified within the gene, but affected dogs had a SINE element 5' upstream of exon 1 in a highly conserved region. Of 545 DNA samples from American Bulldogs, 32 dogs (17 females, 15 males) were homozygous for the polymerase chain reaction fragment. All affected dogs were homozygous, with parents heterozygous for the insertion. Immunolabeling revealed an absence of ichthyin in the epidermis. This is the first description of ARCI associated with decreased expression of NIPAL4 in nonhuman species. © The Author(s) 2014.

Steroid-resistant nephrotic syndrome (SRNS) causes 15% of chronic kidney disease cases. A mutation in 1 of over 40 monogenic genes can be detected in approximately 30% of individuals with SRNS whose symptoms manifest before 25 years of age. However, in many patients, the genetic etiology remains unknown. Here, we have performed whole exome sequencing to identify recessive causes of SRNS. In 7 families with SRNS and facultative ichthyosis, adrenal insufficiency, immunodeficiency, and neurological defects, we identified 9 different recessive mutations in SGPL1, which encodes sphingosine-1-phosphate (S1P) lyase. All mutations resulted in reduced or absent SGPL1 protein and/or enzyme activity. Overexpression of cDNA representing SGPL1 mutations resulted in subcellular mislocalization of SGPL1. Furthermore, expression of WT human SGPL1 rescued growth of SGPL1-deficient dpl1Δ yeast strains, whereas expression of disease-associated variants did not. Immunofluorescence revealed SGPL1 expression in mouse podocytes and mesangial cells. Knockdown of Sgpl1 in rat mesangial cells inhibited cell migration, which was partially rescued by VPC23109, an S1P receptor antagonist. In Drosophila, Sply mutants, which lack SGPL1, displayed a phenotype reminiscent of nephrotic syndrome in nephrocytes. WT Sply, but not the disease-associated variants, rescued this phenotype. Together, these results indicate that SGPL1 mutations cause a syndromic form of SRNS. PMID:28165339

The patient is the centre of a web of relationships, and the impact of his/her disease on family members and caregivers must be taken into account. The aim of this study was to identify the specific instruments that measure the impact of a dermatological disease on the quality of life (QoL) of family members, by performing a systematic search of the literature. Fifteen papers were identified, describing the creation and validation of nine instruments. Four of them concerned atopic dermatitis (Dermatitis Family Index, DFI; Parents' Index QoL Atopic Dermatitis, PiQoL-AD; QoL in primary caregivers of children with atopic dermatitis, QPCAD; Childhood Atopic Dermatitis Impact Scale, CADIS), two measured the impact of psoriasis in family members (Psoriasis Family Index, PFI; FamilyPso), one the impact of epidermolysis bullosa (Epidermolysis Bullosa Burden of Disease, EB-BoD), one of ichthyosis (Family Burden Ichthyosis, FBI), and one was generic for dermatological conditions (Family Dermatology Life Quality Index, FDLQI). The European Academy of Dermatology and Venereology quality of life taskforce recommends that the impact of a skin disease on family and caregivers should be measured as part of any thorough evaluation of the burden of a disease.

The combination of pre-lingual and sensorinerual deafness with skin hyperkeratinization is a relatively rare pathology. Only 11 families affected by this disorder were described in the literature during the last 30 years (from 1975 to 2002). To date, there are no more than 50 cases of this condition known in the world. Modern molecular methods revealed in all such patients a mutation in the GJB2 gene as the primary cause of the disease. We studied a 4 year-old girl with bilateral congenital grade IV sensorineural deafness. Her unusual appearance drew attention aas early as the primary examination; the patient had the deep-set eyes and dry skin over the entire body, she presented with hypotrichosis of the scalp, thin and light-blond hair. Analysis of the nucleotide sequence of the GJB2 gene revealed the substitution of guanine-148 by adenine that led to D50N amino acid substitution. This dominant mutation proved to be the cause of keratitis-ichthyosis-deafness syndrome (KID-syndrome). A review of the literature concerning molecular diagnostics and clinical features of this syndrome is presented. The results of molecular-genetic investigations provided the data on pathogenesis of different variants of sensorineural deafness and the associated genotype-phenotype relationships that may be used as a basis for the further development of the methods for the prevention and treatment of KID-syndrome.

Aberrant Cx26 hemichannels and keratitis-ichthyosis-deafness syndrome: insights into syndromic hearing loss

Mutation of the GJB2 gene, which encodes the connexin 26 (Cx26) gap junction (GJ) protein, is the most common cause of hereditary, sensorineural hearing loss. Cx26 is not expressed in hair cells, but is widely expressed throughout the non-sensory epithelial cells of the cochlea. Most GJB2 mutations produce non-syndromic deafness, but a subset produces syndromic deafness in which profound hearing loss is accompanied by a diverse array of infectious and neoplastic cutaneous disorders that can be fatal. Although GJ channels, which are assembled by the docking of two, so-called hemichannels (HCs), have been the main focus of deafness-associated disease models, it is now evident that the HCs themselves can function in the absence of docking and contribute to signaling across the cell membrane as a novel class of ion channel. A notable feature of syndromic deafness mutants is that the HCs exhibit aberrant behaviors providing a plausible basis for disease that is associated with excessive or altered contributions of Cx26 HCs that, in turn, lead to compromised cell integrity. Here we discuss some of the aberrant Cx26 HC properties that have been described for mutants associated with keratitis-ichthyosis-deafness (KID) syndrome, a particularly severe Cx26-associated syndrome, which shed light on genotype-phenotype relationships and causes underlying cochlear dysfunction.

Keratitis-Ichthyosis-Deafness (KID) syndrome (OMIM 148210) is a congenital ectodermal defect. KID consists of an atypical ichthyosiform erythroderma associated with congenital sensorineural deafness. A rare form of the KID syndrome is a fatal course in the first year of life due to severe skin lesion infections and septicaemia. KID appears to be genetically heterogeneous and may be caused by mutations in connexin 26 or connexin 30 genes. GJB2 mutations in the connexin 26 gene are the main cause of the disease. Most of the cases caused by GJB2 mutations are sporadic, but dominant transmission has also been described. To date, the rare lethal form of the disease has been only observed in two Caucasian sporadic patients with the GJB2 mutation, with the p.Gly45Glu (G45E) arising de novo. We have reported an African family with dizygotic twins suffering from a lethal form of KID. The dizygosity of the twins was confirmed by microsatellite markers. The two patients were heterozygous for the G45E mutation of GJB2, whereas the mutation was not detected in the two parents. The unusual transmission of the disease observed in this family could be explained by the occurrence of a somatic or more probably a germinal mosaic in one of the parents.

Mutations in Cx26 gene are found in most cases of human genetic deafness. Some mutations produce syndromic deafness associated with skin disorders, like Keratitis Ichthyosis Deafness syndrome (KID). Because in the human skin Cx26 is co-expressed with other connexins, like Cx43 and Cx30, and since KID syndrome is inherited as autosomal dominant condition, it is possible that KID mutations change the way Cx26 interacts with other co-expressed connexins. Indeed, some Cx26 syndromic mutations showed gap junction dominant negative effect when co-expressed with wild type connexins, including Cx26 and Cx43. The nature of these interactions and the consequences on hemichannels and gap junction channels functions remain unknown. In this study we demonstrate that syndromic mutations at the N-terminus segment of Cx26, change connexin oligomerization compatibility, allowing aberrant interactions with Cx43. Strikingly, heteromeric oligomer formed by Cx43/Cx26 (syndromic mutants) show exacerbated hemichannel activity, but nonfunctional gap junction channels; this also occurs for those Cx26 KID mutants that do not show functional homomeric hemichannels. Heterologous expression of these hyperactive heteromeric hemichannels increases cell membrane permeability, favoring ATP release and Ca2+ overload. The functional paradox produced by oligomerization of Cx43 and Cx26 KID mutants could underlie the severe syndromic phenotype in human skin. PMID:25625422

Connexins (Cxs) are transmembranous proteins that connect adjacent cells via channels known as gap junctions. The N-terminal 21 amino acids of Cx26 are located at the cytoplasmic side of the channel pore and are thought to be essential for the regulation of channel selectivity. We have found a novel mutation, N14Y, in the N-terminal domain of Cx26 in a case of keratitis-ichthyosis-deafness syndrome. Reduced gap junctional intercellular communication was observed in the patient’s keratinocytes by the dye transfer assay using scrape-loading methods. The effect of this mutation on molecular structure was investigated using synthetic N-terminal peptides from both wild-type and mutated Cx26. Two-dimensional 1H nuclear magnetic resonance and circular dichroism measurements demonstrated that the secondary structures of these two model peptides are similar to each other. However, several novel nuclear Overhauser effect signals appeared in the N14Y mutant, and the secondary structure of the mutant peptide was more susceptible to induction of 2,2,2-trifluoroethanol than wild type. Thus, it is likely that the N14Y mutation induces a change in local structural flexibility of the N-terminal domain, which is important for exerting the activity of the channel function, resulting in impaired gap junctional intercellular communication.

Acral peeling skin syndrome (APSS) is a rare autosomal recessive condition, characterized by asymptomatic peeling of the skin of the hands and feet, often linked to mutations in the gene TGM5. However, more recently recessive loss of function mutations in CSTA, encoding cystatin A, have been linked with APSS and exfoliative ichthyosis. We describe the clinical features in two sisters with APSS, associated with a novel large homozygous deletion encompassing exon 1 of CSTA. © 2015 British Association of Dermatologists.

Dowling Degos disease is a rare, reticulate pigmentary disorder with variable phenotypic expression that manifests as hyperpigmented macules and reticulate pigmentary anomaly of the flexures. Many variants of this condition and its overlap with other reticulate pigmentary disorders have been reported in the literature. We present here two cases of DDD with follicular localization, both clinically and histologically. It was associated with ichthyosis vulgaris in one case. Follicular DDD is an uncommon variant of this evolving dermatosis. Our report supports the possible role for disordered follicular keratinisation in its pathogenesis.

Four siblings with hepatic fibrosis are described. The liver damage in these patients was secondary to chronic ingestion of massive doses of vitamin A for congenital ichthyosis. Although the extrahepatic manifestations were helpful in the diagnosis of hypervitaminosis A, the distinctive features of hepatic histopathology were confirmatory. The plasma concentrations of vitamin A and retinol-binding protein were misleading. The recovery from the liver damage in these patients was slow despite a complete withdrawal of the vitamin A intake. These cases show the importance of hepatic vitamin A assessment in the diagnosis of hepatic fibrosis.

Fatty liver disease is mainly caused by alcohol consumption, excessive body weight, dyslipidemia and impaired glucose tolerance, but inherited disorders can sometimes be involved. We report the case of a 40-year-old woman with steatohepatitis and severe portal hypertension, associated with ichthyosis, cataract and hypoacusia. The clinical, pathological and genetic findings were consistent with a diagnosis of Chanarin-Dorfman syndrome (CDS), a rare autosomal recessive inherited neutral lipid storage disorder, and genetic analysis showed that a novel ABHD5 mutation is responsible.

A Mouse Model of Harlequin Ichthyosis Delineates a Key Role for Abca12 in Lipid Homeostasis

Harlequin Ichthyosis (HI) is a severe and often lethal hyperkeratotic skin disease caused by mutations in the ABCA12 transport protein. In keratinocytes, ABCA12 is thought to regulate the transfer of lipids into small intracellular trafficking vesicles known as lamellar bodies. However, the nature and scope of this regulation remains unclear. As part of an original recessive mouse ENU mutagenesis screen, we have identified and characterised an animal model of HI and showed that it displays many of the hallmarks of the disease including hyperkeratosis, loss of barrier function, and defects in lipid homeostasis. We have used this model to follow disease progression in utero and present evidence that loss of Abca12 function leads to premature differentiation of basal keratinocytes. A comprehensive analysis of lipid levels in mutant epidermis demonstrated profound defects in lipid homeostasis, illustrating for the first time the extent to which Abca12 plays a pivotal role in maintaining lipid balance in the skin. To further investigate the scope of Abca12's activity, we have utilised cells from the mutant mouse to ascribe direct transport functions to the protein and, in doing so, we demonstrate activities independent of its role in lamellar body function. These cells have severely impaired lipid efflux leading to intracellular accumulation of neutral lipids. Furthermore, we identify Abca12 as a mediator of Abca1-regulated cellular cholesterol efflux, a finding that may have significant implications for other diseases of lipid metabolism and homeostasis, including atherosclerosis.

Objective The capacity of neutrophils to eradicate bacterial infections is dependent on normal development and the activation of functional responses, which include chemotaxis and the generation of oxygen radicals during the respiratory burst. A unique feature of the neutrophil is its highly lobulated nucleus, which is thought to facilitate chemotaxis but may also play a role in other critical neutrophil functions. Nuclear lobulation is dependent on the expression of the inner nuclear envelope protein, the lamin B receptor (LBR), mutations of which cause hypolobulated neutrophil nuclei in human Pelger-Huët anomaly (PHA) and the "ichthyosis" (ic) phenotype in mice. In this study we have investigated roles for LBR in mediating neutrophil development and the activation of multiple neutrophil functions, including chemotaxis and the respiratory burst. Materials and Methods A progenitor EML cell line was generated from an ic/ic mouse, and derived cells that lacked LBR expression were induced to mature neutrophils and then examined for abnormal morphology and functional responses. Results Neutrophils derived from EML-ic/ic cells exhibited nuclear hypolobulation identical to that observed in ichthyosis mice. The ic/ic neutrophils also displayed abnormal chemotaxis, supporting the notion that nuclear segmentation augments neutrophil extravasation. Furthermore, promyelocytic forms of ic/ic cells displayed decreased proliferative responses and produced a deficient respiratory burst upon terminal maturation. Conclusions Our studies of promyelocytes that lack LBR expression have identified roles for LBR in regulating not only the morphologic maturation of the neutrophil nucleus but also proliferative and functional responses that are critical to innate immunity.

Moisturizers increase skin hydration and can serve as adjunctive care in dermatologic conditions such as xerosis, psoriasis vulgaris, atopic dermatitis and ichthyosis, in which dry skin is implicated. A non-irritating hydrating lotion (CDA lotion) was recently developed. We assessed the effect of CDA lotion on skin hydration in two randomized, evaluator-blind and intra-individual comparison studies. After a single application, CDA lotion induced significantly greater hydration than the non-treated control for at least 24 hours (p < 0.001). After 4 days of twice-daily application, compared with the non-treated control, CDA lotion induced significantly greater skin hydration up to 3 days after treatment cessation (p < 0.05) and significant improvement in the clinical skin dryness score up to 7 days after treatment cessation (p < 0.05). The immediate and cumulative hydration effects of CDA lotion were also compared to those of several currently available moisturizing products. In summary, application of CDA lotion increases skin hydration and alleviates the condition of skin dryness.

THE INFLUENCE OF THE CHEMICAL NATURE OF SOLID PARTICLES ON THEIR CATAPHORETIC P.D. IN AQUEOUS SOLUTIONS

PubMed Central

Loeb, Jacques

1923-01-01

1. The effect of eight salts, NaCl, Na2SO4, Na4Fe(CN)6, CaCl2, LaCl3, ThCl4, and basic and acid fuchsin on the cataphoretic P.D. between solid particles and aqueous solutions was measured near the point of neutrality of water (pH 5.8). It was found that without the addition of electrolyte the cataphoretic P.D. between particles and water is very minute near the point of neutrality (pH 5.8), often less than 10 millivolts, if care is taken that the solutions are free from impurities. Particles which in the absence of salts have a positive charge in water near the point of neutrality (pH 5.8) are termed positive colloids and particles which have a negative charge under these conditions are termed negative colloids. 2. If care is taken that the addition of the salt does not change the hydrogen ion concentration of the solution (which in these experiments was generally pH 5.8) it can be said in general, that as long as the concentration of salts is not too high, the anions of the salt have the tendency to make the particles more negative (or less positive) and that cations have the opposite effect; and that both effects increase with the increasing valency of the ions. As soon as a maximal P.D. is reached, which varies for each salt and for each type of particles, a further addition of salt depresses the P.D. again. Aside from this general tendency the effects of salts on the P.D. are typically different for positive and negative colloids. 3. Negative colloids (collodion, mastic, Acheson's graphite, gold, and metal proteinates) are rendered more negative by low concentrations of salts with monovalent cation (e.g. Na) the higher the valency of the anion, though the difference in the maximal P.D. is slight for the monovalent Cl and the tetravalent Fe(CN)6 ions. Low concentrations of CaCl2 also make negative colloids more negative but the maximal P.D. is less than for NaCl; even LaCl3 increases the P.D. of negative particles slightly in low concentrations. ThCl4 and basic fuchsin, however, seem to make the negative particles positive even in very low concentrations. 4. Positive colloids (ferric hydroxide, calcium oxalate, casein chloride—the latter at pH 4.0) are practically not affected by NaCl, are rendered slightly negative by high concentrations of Na2SO4, and are rendered more negative by Na4Fe(CN)6 and acid dyes. Low concentrations of CaCl2 and LaCl3 increase the positive charge of the particles until a maximum is reached after which the addition of more salt depresses the P.D. again. 5. It is shown that alkalies (NaOH) act on the cataphoretic P.D. of both negative and positive particles as Na4Fe(CN)6 does at the point of neutrality. 6. Low concentrations of HCl raise the cataphoretic P.D. of particles of collodion, mastic, graphite, and gold until a maximum is reached, after which the P.D. is depressed by a further increase in the concentration of the acid. No reversal in the sign of charge of the particle occurs in the case of collodion, while if a reversal occurs in the case of mastic, gold, and graphite, the P.D. is never more than a few millivolts. When HCl changes the chemical nature of the colloid, e.g. when HCl is added to particles of amphoteric electrolytes like sodium gelatinate, a marked reversal will occur, on account of the transformation of the metal proteinate into a protein-acid salt. 7. A real reversal in the sign of charge of positive particles occurs, however, at neutrality if Na4Fe(CN)6 or an acid dye is added; and in the case of negative colloids when low concentrations of basic dyes or minute traces of ThCl4 are added. 8. Flocculation of the suspensions by salts occurs when the cataphoretic P.D. reaches a critical value which is about 14 millivolts for particles of graphite, gold, or mastic or denatured egg albumin; while for collodion particles it was about 16 millivolts. A critical P.D. of about 15 millivolts was also observed by Northrop and De Kruif for the flocculation of certain bacteria. PMID:19872064

Recently, mutations in PNPLA2 encoding adipose triglyceride lipase (ATGL) were reported to underlie a neutral lipid storage disease (NLSD) subgroup characterized by mild myopathy and the absence of ichthyosis. In the present study a novel homozygous PNPLA2 mutation c.475_478dupCTCC (p.Gln160ProfsX19) in the patatin domain, the ATGL active site, was detected in a woman with NLSD and severe myopathy. The present results suggest that a premature truncation mutation in the patatin domain causes NLSD with severe myopathy.

Physical and visual state of 100-year-old Lippman color photographs

In 1891 Gabriel Lippmann demonstrated a photographic process which records full color images on black and white emulsions. It is closely related to Denisyuk's reflection holography technique, which he named after Lippmann. After a historical introduction I will speak on the physical state and visual appearance of Lippmann-process color images produced at the turn of the century by Lippmann and a limited number of other practitioners. Images made on albumin, collodion and gelatine will be discussed, based on my examination of more than 400 images held in public and private collections. Examples of old original images (and some new work) will be shown. It is possible to conclude that, if properly excited, such images will be stable in their beautiful rendition of color and extremely high resolution almost indefinitely.

STUDIES ON THE PURIFICATION OF BACTERIOPHAGE

PubMed Central

Kalmanson, G.; Bronfenbrenner, J.

1939-01-01

A simple method of concentrating and purifying bacteriophage has been described. The procedure consisted essentially in collecting the active agent on a reinforced collodion membrane of a porosity that would just retain all the active agent and permit extraneous material to pass through. Advantage was taken of the fact that B. coli will proliferate and regenerate bacteriophage in a completely diffusible synthetic medium with ammonia as the only source of nitrogen, which permitted the purification of the bacteriophage by copious washing. The material thus obtained was concentrated by suction and after thorough washing possessed all the activity of the original filtrate. It was labile, losing its activity in a few days on standing, and was quickly and completely inactivated upon drying. This material contained approximately 15 per cent of nitrogen and with 2 or 3 mg. samples of inactive dry residue it was possible to obtain positive protein color tests. The concentrated and purified bacteriophage has about 10–14 mg. of nitrogen, or 6 x 10–17 gm. of protein per unit of lytic activity. Assuming that each unit of activity represents a molecule, the calculated maximum average molecular weight would be approximately 36,000,000, and on the assumption of a spherical shape of particles and a density of 1.3, the calculated radius would be about 22 millimicra. By measurement of the diffusion rate, the average radius of particle of the fraction of the purified bacteriophage which diffuses most readily through a porous plate was found to be of the order of magnitude of 9 millimicra, or of a calculated molecular weight of 2,250,000. Furthermore, when this purified bacteriophage was fractionated by forcing it through a thin collodion membrane, which permits the passage of only the smaller particles, it was possible to demonstrate in the ultrafiltrate active particles of about 2 millimicra in radius, and of a calculated molecular weight of 25,000. It was of interest to apply this method of purification to a staphylococcus bacteriophage. Since this organism does not readily grow in synthetic medium, a diffusate of yeast extract medium was employed. The better of two preparations contained about 10–12 mg. of nitrogen per unit of lytic activity. Although this is about one hundred times the amount of nitrogen found in an active unit of B. coli bacteriophage, nevertheless, the diffusion rate experiments gave results which paralleled those obtained with the coliphage. The diffusible particles of the crude staphylococcus bacteriophage had a radius of about 7 millimicra, and a calculated molecular weight of about 1,000,000, while the particles of the same phage which appeared in the ultrafiltrate through a thin collodion membrane had a radius of about 2.4 millimicra and a calculated molecular weight of about 45,000. It appears, therefore, that the active principle is distributed as particles of widely different sizes. However, since the smaller particles have all the properties of bacteriophage, the larger particles probably do not represent free molecules, but either are aggregates, or more likely, inactive colloids to which the active agent is adsorbed. The protein isolated, which bears the phage activity, is capable of stimulating the production of antilytic antibodies on parenteral injection into rabbits or guinea pigs. It retains its specific antigenicity when inactivated by formalin, but not when inactivated by drying. PMID:19873149

Hepatocyte growth factor activator inhibitor type 1 (HAI-1)/serine protease inhibitor, Kunitz type 1 (SPINT1) is a membrane-bound, serine proteinase inhibitor initially identified as an inhibitor of hepatocyte growth factor activator. It also inhibits matriptase and prostasin, both of which are membrane-bound serine proteinases that have critical roles in epidermal differentiation and function. In this study, skin and hair phenotypes of mice lacking the Hai-1/Spint1 gene were characterized. Previously, we reported that the homozygous deletion of Hai-1/Spint1 in mice resulted in embryonic lethality attributable to impaired placental development. To test the role of Hai-1/Spint1 in mice, the placental function of Hai-1/Spint1-mutant mice was rescued. Injection of Hai-1/Spint1+/+ blastocysts with Hai-1/Spint1−/− embryonic stem cells successfully generated high-chimeric Hai-1/Spint1−/− embryos (B6Hai-1−/−High) with normal placentas. These embryos were delivered without apparent developmental abnormalities, confirming that embryonic lethality of Hai-1/Spint1−/− mice was caused by placental dysfunction. However, newborn B6Hai-1−/−High mice showed growth retardation and died by 16 days. These mice developed scaly skin because of hyperkeratinization, reminiscent of ichthyosis, and abnormal hair shafts that showed loss of regular cuticular septation. The interfollicular epidermis showed acanthosis with enhanced Akt phosphorylation. Immunoblot analysis revealed altered proteolytic processing of profilaggrin in Hai-1/Spint1-deleted skin with impaired generation of filaggrin monomers. These findings indicate that Hai-1/Spint1 has critical roles in the regulated keratinization of the epidermis and hair development. PMID:18832587

Ichthyoses are a clinically and genetically heterogeneous group of genodermatoses associated with abnormal scaling of the skin over the whole body. Mutations in nine genes are known to cause non-syndromic forms of autosomal-recessive congenital ichthyosis (ARCI). However, not all genetic causes for ARCI have been discovered to date. Using whole-exome sequencing (WES) and multigene panel screening, we identified 6 ARCI-affected individuals from three unrelated families with mutations in Sulfotransferase family 2B member 1 (SULT2B1), showing their causative association with ARCI. Cytosolic sulfotransferases form a large family of enzymes that are involved in the synthesis and metabolism of several steroids in humans. We identified four distinct mutations including missense, nonsense, and splice site mutations. We demonstrated the loss of SULT2B1 expression at RNA and protein levels in keratinocytes from individuals with ARCI by functional analyses. Furthermore, we succeeded in reconstructing the morphologic skin alterations in a 3D organotypic tissue culture model with SULT2B1-deficient keratinocytes and fibroblasts. By thin layer chromatography (TLC) of extracts from these organotypic cultures, we could show the absence of cholesterol sulfate, the metabolite of SULT2B1, and an increased level of cholesterol, indicating a disturbed cholesterol metabolism of the skin upon loss-of-function mutation in SULT2B1. In conclusion, our study reveals an essential role for SULT2B1 in the proper development of healthy human skin. Mutation in SULT2B1 leads to an ARCI phenotype via increased proliferation of human keratinocytes, thickening of epithelial layers, and altered epidermal cholesterol metabolism.

Keratitis-ichthyosis-deafness (KID) syndrome is a rare congenital ectodermal disorder, caused by heterozygous missense mutation in GJB2, encoding the gap junction protein connexin 26. The commonest mutation is the p.Asp50Asn mutation, and only a few other mutations have been described to date. To report the fatal clinical course and characterize the genetic background of a premature male neonate with the clinical and histological features of KID syndrome. Genomic DNA was extracted from peripheral blood and used for PCR amplification of the GJB2 gene. Direct sequencing was used for mutation analysis. The clinical features included hearing impairment, ichthyosiform erythroderma with hyperkeratotic plaques, palmoplantar keratoderma, alopecia of the scalp and eyelashes, and a thick vernix caseosa-like covering of the scalp. On histological analysis, features characteristic of KID syndrome, such as acanthosis and papillomatosis of the epidermis with basket-weave hyperkeratosis, were seen. The skin symptoms were treated successfully with acitretin 0.5 mg/kg. The boy developed intraventricular and intracerebral haemorrhage, leading to hydrocephalus. His condition was further complicated by septicaemia and meningitis caused by infection with extended-spectrum beta-lactamase-producing Klebsiella pneumoniae. Severe respiratory failure followed, and the child died at 46 weeks of gestational age (13 weeks postnatally). Sequencing of the GJB2 gene showed that the child was heterozygous for a novel nucleotide change, c.263C>T, in exon 2, leading to a substitution of alanine for valine at position 88 (p.Ala88Val). This study has identified a new heterozygous de novo mutation in the Cx26 gene (c.263C>T; p.Ala88Val) leading to KID syndrome. © The Author(s). CED © 2010 British Association of Dermatologists.

Deletion of the entire steroid sulfatase (STS) gene is the most common molecular defect in X-linked ichthyosis (XLI) patients. Usually, additional flanking sequences are also missing. The aim of this study was to estimate the extent of deletions in an ethnically heterogeneous population of Israeli XLI patients. Multiplex polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) techniques were applied in the analysis of blood samples of 24 patients and amniotic cells of seven affected fetuses from 22 unrelated families. In 19 families, a large deletion of the 2-3 megabase was found. It included the whole STS gene and spanned adjacent areas up- and downstream between the loci DXS 1139 and DXS 1132. Two unrelated families of Iraqi ancestry had a partial deletion of the gene and its centromeric adjacent sequence. In another family, the telomeric end of the extragenic segment was only partially missing. Application of FISH on metaphase blood cells and interphase amniotic cells confirmed the diagnosis of XLI in all patients, except the three with partial intragenic deletion. In those cases, the remaining fraction of the gene was sufficient to provide a false negative result. Diagnosis of carriers and prenatal diagnosis in uncultured cells was applicable only by FISH. Our study revealed a remarkable heterogeneity in the deletion pattern among Israeli patients with XLI. This heterogeneity could not be attributed to specific ethnic groups because of the small size of the study group. More studies involving patients of various ancestries should be carried out. In addition, this study demonstrated the usefulness of the FISH technique in the prenatal diagnosis of fetuses with suspected XLI.

Revertant mosaicism (RM) is a naturally occurring phenomenon where the pathogenic effect of a germline mutation is corrected by a second somatic event. Development of healthy-looking skin due to RM has been observed in patients with various inherited skin disorders, but not in connexin-related disease. We aimed to clarify the underlying molecular mechanisms of suspected RM in the skin of a patient with keratitis-ichthyosis-deafness (KID) syndrome. The patient was diagnosed with KID syndrome due to characteristic skin lesions, hearing deficiency and keratitis.

At age 20, the patient developed spots of healthy-looking skin that grew in size and number within widespread erythrokeratodermic lesions. Ultra-deep sequencing of two healthy-looking skin biopsies identified five somatic nonsynonymous mutations, independently present in cis with the p.Asp50Asn mutation. Functional studies of Cx26 in HeLa cells revealed co-expression of Cx26-Asp50Asn and wild-type Cx26 in gap junction channel plaques. However, Cx26-Asp50Asn with the second-site mutations identified in the patient displayed no formation of gap junction channel plaques. We argue that the second-site mutations independently inhibit Cx26-Asp50Asn expression in gap junction channels, reverting the dominant negative effect of the p.Asp50Asn mutation. Finally to our knowledge, this is the first time RM has been reported to result in the development of healthy-looking skin in a patient with KID syndrome.« less

Atopic dermatitis (AD), Netherton syndrome (NS) and peeling skin syndrome type B (PSS) may show some clinical phenotypic overlap. Corneodesmosomes are crucial for maintaining stratum corneum integrity and the components' localization can be visualized by immunostaining tape-stripped corneocytes. In normal skin, they are detected at the cell periphery. To determine whether AD, NS, PSS and ichthyosis vulgaris (IV) have differences in the corneodesmosomal components' distribution and corneocytes surface areas. Corneocytes were tape-stripped from a control group (n=12) and a disease group (37 AD cases, 3 IV cases, 4 NS cases, and 3 PSS cases), and analyzed with immunofluorescent microscopy. The distribution patterns of corneodesmosomal components: desmoglein 1, corneodesmosin, and desmocollin 1 were classified into four types: peripheral, sparse diffuse, dense diffuse and partial diffuse. Corneocyte surface areas were also measured. The corneodesmosome staining patterns were abnormal in the disease group. Other than in the 3 PSS cases, all three components showed similar patterns in each category. In lesional AD skin, the dense diffuse pattern was prominent. A high rate of the partial diffuse pattern, loss of linear cell-cell contacts, and irregular stripping manners were unique to NS. Only in PSS was corneodesmosin staining virtually absent. The corneocyte surface areas correlated significantly with the rate of combined sparse and dense diffuse patterns of desmoglein 1. This method may be used to assess abnormally differentiated corneocytes in AD and other diseases tested. In PSS samples, tape stripping analysis may serve as a non-invasive diagnostic test.

Filaggrin is a structural protein that is fundamental in the development and maintenance of the skin barrier. The function of filaggrin and its involvement in various cutaneous and extracutaneous disorders has been the subject of considerable research in recent years. Mutations in FLG, the gene that encodes filaggrin, have been shown to cause ichthyosis vulgaris, increase the risk of atopic dermatitis and other atopic diseases, and exacerbate certain conditions. The present article reviews the current knowledge on the role of filaggrin in the skin barrier, FLG mutations, and the consequences of filaggrin deficiency.

Davies, William

2016-11-09

The internet, and social media platforms, are increasingly being used by substantial sectors of the worldwide population. By engaging effectively with online and social media, scientists and clinicians can obtain unprecedented access to relatively large cohorts of individuals with rare diseases, as well as their relatives, carers and professionals involved in their healthcare. Online surveys of these stakeholder groups may provide important new insights into rare conditions and their management relatively quickly and easily, with the possibility of rapid translation into healthcare interventions and policy. Here, I describe our recent positive experience with the online survey approach to a rare disease (X-linked ichthyosis), and review its advantages and limitations.

A man with nevoid hyperkeratosis of the areola.

English, J C; Coots, N V

1996-05-01

Nevoid hyperkeratosis of the nipple and areola is a unique clinical entity and a diagnosis of exclusion. The patient presenting with nipple/areolar hyperkeratosis must be examined carefully for other underlying cutaneous diseases such as epidermal nevi, ichthyosis, acanthosis nigricans, Darier's disease, cutaneous T-cell lymphoma, and other chronic skin dermatitides that may be responsible for the changes. If no other clinical findings are evident, the diagnosis can be made. Although the disorder is more common in women of childbearing age, men may show nevoid changes after estrogen therapy or idiopathically. The use of topical 12 percent lactic acid lotion (Lac-Hydrin) resolves the skin changes over a six-month period.

Acral peeling skin syndrome resulting from a homozygous nonsense mutation in the CSTA gene encoding cystatin A.

2013-01-01

Acral peeling skin syndrome (APSS) is a clinically and genetically heterogeneous disorder. We used whole-exome sequencing to identify the molecular basis of APSS in a consanguineous Jordanian-American pedigree. We identified a homozygous nonsense mutation (p.Lys22X) in the CSTA gene, encoding cystatin A, that was confirmed using Sanger sequencing. Cystatin A is a protease inhibitor found in the cornified cell envelope, and loss-of-function mutations have previously been reported in two cases of exfoliative ichthyosis. Our study expands the molecular pathology of APSS and demonstrates the value of next-generation sequencing in the genetic characterization of inherited skin diseases. © 2013 Wiley Periodicals, Inc.

Louis Ducos du Huron (1837-1920) dedicated his entire life to the elaboration of physical-chemical processes for color photography. This study aimed at highlighting his unique contribution to three-color printing through 1) an in-depth review of the many protocols he published and 2) the synchrotron-based IR and X-ray microanalysis of fragments sampled in three artworks. Ducos du Hauron's method relied on the preparation and assembly of three monochromes (red, blue, yellow). This study brings to light complex multistep recipes based on photochemistry (carbon print), organic, and inorganic chemistry. The various ingredients involved (e.g., pigments, dichromate gelatin, collodion, resin) were identified and localized through their spectroscopic signature, confirming the relevance of synchrotron spectromicroscopy for the characterization of historical photographs. The impressive correlation between texts and chemical analyses calls for a wider application to the history of photography. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Substantial prevalence of microdeletions of the Y-chromosome in infertile men with idiopathic azoospermia and oligozoospermia detected using a sequence-tagged site-based mapping strategy

Genes on the long arm of Y (Yq), particularly within interval 6, are believed to play a critical role in human spermatogenesis. Cytogenetically detectable deletions of this region are associated with azoospermia in men, but are relatively uncommon. The objective of this study was to validate a sequence-tagged site (STS)-mapping strategy for the detection of Yq microdeletions and to use this method to determine the proportion of men with idiopathic azoospermia or severe oligozoospermia who carry microdeletions in Yq. STS mapping of a sufficiently large sample of infertile men should also help further localize the putative gene(s) involved in themore » pathogenesis of male infertility. Genomic DNA was extracted from peripheral leukocytes of 16 normal fertile men, 7 normal fertile women, 60 infertile men, and 15 patients with the X-linked disorder, ichthyosis. PCR primers were synthesized for 26 STSs that span Yq interval 6. None of the 16 normal men of known fertility had microdeletions. Seven normal fertile women failed to amplify any of the 26 STSs, providing evidence of their Y specificity. No microdeletions were detected in any of the 15 patients with ichthyosis. Of the 60 infertile men typed with 26 STSs, 11 (18%; 10 azoospermic and 1 oligozoospermic) failed to amplify 1 or more STS. Interestingly, 4 of the 11 patients had microdeletions in a region that is outside the Yq region from which the DAZ (deleted in azoospermia gene region) gene was cloned. In an additional 3 patients, microdeletions were present both inside and outside the DAZ region. The physical locations of these microdeletions provide further support for the concept that a gene(s) on Yq deletion interval 6 plays an important role in spermatogenesis. The presence of deletions that do not overlap with the DAZ region suggests that genes other than the DAZ gene may also be implicated in the pathogenesis of some subsets of male infertility. 48 refs., 2 figs., 2 tabs.« less

Hereditary keratin disorders of the skin and its appendages comprise a large group of clinically heterogeneous disfiguring blistering and ichthyotic diseases, primarily characterized by the loss of tissue integrity, blistering and hyperkeratosis in severely affected tissues. Pathogenic mutations in keratins cause these afflictions. Typically, these mutations in concert with characteristic features have formed the basis for improved disease diagnosis, prognosis and most recently therapy development. Examples include epidermolysis bullosa simplex, keratinopathic ichthyosis, pachyonychia congenita and several other tissue-specific hereditary keratinopathies. Understanding the molecular and genetic events underlying skin dysfunction has initiated alternative treatment approaches that may provide novel therapeutic opportunities for affected patients. Animal and in vitro disease modelling studies have shed more light on molecular pathogenesis, further defining the role of keratins in disease processes and promoting the translational development of new gene and pharmacological therapeutic strategies. Given that the molecular basis for these monogenic disorders is well established, gene therapy and drug discovery targeting pharmacological compounds with the ability to reinforce the compromised cytoskeleton may lead to promising new therapeutic strategies for treating hereditary keratinopathies. In this review, we will summarize and discuss recent advances in the preclinical and clinical modelling and development of gene, natural product, pharmacological and protein-based therapies for these disorders, highlighting the feasibility of new approaches for translational clinical therapy.

2008-06-01

The discovery that null mutations in the filaggrin gene (FLG) are associated with atopic eczema represents the single most significant breakthrough in understanding the genetic basis of this complex disorder. The association has been replicated in multiple independent studies during the past 2 years with the use of various methodologies, from populations in Europe, the United States, and Japan. Filaggrin plays a key role in epidermal barrier function, and its association with atopic eczema emphasizes the importance of barrier dysfunction in eczema pathogenesis. This review aims to summarize the current state of knowledge regarding the role of FLG mutations in ichthyosis vulgaris, atopic eczema, and other skin disorders, with an emphasis on potential clinical applications. Further research is needed to clarify the precise role of filaggrin in skin and systemic atopic disease, to pave the way for novel therapeutic interventions.

The discovery, in 2006, that loss-of-function mutations in the filaggrin gene (FLG) are the cause of ichthyosis vulgaris – the most common disorder of keratinization – and also a strong genetic risk factor for atopic eczema, marked a significant breakthrough in the understanding of eczema pathogenesis. Subsequent investigations of the role of FLG null mutations have identified a series of significant associations with atopic disease phenotypes, including atopic asthma, allergic rhinitis and peanut allergy. However, many questions remain to be answered in relation to the precise mechanisms by which deficiency of an intracellular protein expressed primarily in the differentiating epidermis may contribute to the development of cutaneous and systemic pathology. This review aims to highlight the key milestones in filaggrin research over the past 25 years, to discuss the mechanistic, clinical and therapeutic implications and to consider possible future directions for ongoing investigation.

Cold-stage microscopy system for fast-frozen liquids.

Talmon, Y; Davis, H T; Scriven, L E; Thomas, E L

1979-06-01

The least artifact-laden fixation technique for examining colloidal suspensions, microemulsions, and other microstructured liquids in the electron microscope appears to be thermal fixation, i.e., ultrafast freezing of the liquid specimen. For rapid-enough cooling and for observation in TEM/STEM a thin sample is needed. The need is met by trapping a thin layer ( approximately 100 nm) of liquid between two polyimide films ( approximately 40 nm thickness) mounted on copper grids and immersing the resulting sandwich in liquid nitrogen at its melting point. For liquids containing water, polyimides films are used since this polymer is far less susceptible to the electron beam damage observed for the commonly used polymer films such as Formvar and collodion in contact with ice. Transfer of the frozen sample into the microscope column without deleterious frost deposition and warming is accomplished with a new transfer module for the cooling stage of the JEOL JEM-100CX microscope, which makes a true cold stage out of a device originally intended for cooling specimens inside the column. Sample results obtained with the new fast-freeze, cold-stage microscopy system are given.

Undetectable maternal serum unconjugated estriol levels in the second-trimester screening test have been associated with congenital pathology and an adverse pregnancy outcome. We reviewed outcomes of pregnancies with undetectable levels of estriol (<0.25 ng/ml) in the triple-marker screening test and assessed the clinical value of this finding. We studied estriol values in 6,018 pregnant patients who underwent a triple-marker screening test during a seven-year period. 26 women had estriol levels at or below the sensitivity of the assay. The most common explanations were dating errors, prematurity, growth restriction and X-linked ichthyosis. We also observed one fetal death at 16 weeks, one severe threatened fetal abortion, one case of multiple congenital anomalies and one case of isolated adrenocorticotropin hormone deficiency. There were 6 women remaining with unexplained undetectable estriol. Undetectable maternal estriol values may indicate a severe fetal pathology and should lead to further investigations.

The keratitis-ichthyosis-deafness (KID) syndrome is caused by mutations in the gap junctional channel protein connexin 26 (Cx26), among them the mutation Cx26S17F. Heterozygous Cx26S17F mice resemble the human KID syndrome, i.e. exhibiting epidermal hyperplasia and hearing impairments. Newborn Cx26S17F mice show a defective epidermal water barrier as well as altered epidermal lipid secretion and location. Linoleoyl ω-esterified ceramides are strongly decreased on the skin surface of Cx26S17F mice. Moreover, the epidermal calcium gradient is altered in the mutant mice. These alterations may be caused by an abnormal Cx26S17F channel function that leads to a defective epidermal water barrier, which in turn may trigger the hyperproliferation seen in the KID syndrome.

Generalized peeling skin disease is an autosomal-recessive ichthyosiform erythroderma characterized by lifelong patchy peeling of the skin. After genome-wide linkage analysis, we have identified a homozygous nonsense mutation in CDSN in a large consanguineous family with generalized peeling skin, pruritus, and food allergies, which leads to a complete loss of corneodesmosin. In contrast to hypotrichosis simplex, which can be associated with specific dominant CDSN mutations, peeling skin disease is characterized by a complete loss of CDSN expression. The skin phenotype is consistent with a recent murine Cdsn knockout model. Using three-dimensional human skin models, we demonstrate that lack of corneodesmosin causes an epidermal barrier defect supposed to account for the predisposition to atopic diseases, and we confirm the role of corneodesmosin as a decisive epidermal adhesion molecule. Therefore, peeling skin disease will represent a new model disorder for atopic diseases, similarly to Netherton syndrome and ichthyosis vulgaris in the recent past.

Patients with primary serine biosynthetic defects manifest with intellectual disability, microcephaly, ichthyosis, seizures and peripheral neuropathy. The underlying pathogenesis of peripheral neuropathy in these patients has not been elucidated, but could be related to a decrease in the availability of certain classical sphingolipids, or to an increase in atypical sphingolipids. Here, we show that patients with primary serine deficiency have a statistically significant elevation in specific atypical sphingolipids, namely deoxydihydroceramides of 18-22 carbons in acyl length. We also show that patients with aberrant plasma serine and alanine levels secondary to mitochondrial disorders also display peripheral neuropathy along with similar elevations of atypical sphingolipids. We hypothesize that the etiology of peripheral neuropathy in patients with primary mitochondrial disorders is related to this elevation of deoxysphingolipids, in turn caused by increased availability of alanine and decreased availability of serine. These findings could have important therapeutic implications for the management of these patients. Copyright © 2018 Elsevier Inc. All rights reserved.

Self-Compassion Promotes Personal Improvement From Regret Experiences via Acceptance.

PubMed

Zhang, Jia Wei; Chen, Serena

2016-02-01

Why do some people report more personal improvement from their regret experiences than others? Three studies examined whether self-compassion promotes personal improvement derived from recalled regret experiences. In Study 1, we coded anonymous regret descriptions posted on a blog website. People who spontaneously described their regret with greater self-compassion were also judged as having expressed more personal improvement. In Study 2, higher trait self-compassion predicted greater self-reported and observer-rated personal improvement derived from recalled regret experiences. In Study 3, people induced to take a self-compassionate perspective toward a recalled regret experience reported greater acceptance, forgiveness, and personal improvement. A multiple mediation analysis comparing acceptance and forgiveness showed self-compassion led to greater personal improvement, in part, through heightened acceptance. Furthermore, self-compassion's effects on personal improvement were distinct from self-esteem and were not explained by adaptive emotional responses. Overall, the results suggest that self-compassion spurs positive adjustment in the face of regrets. © 2015 by the Society for Personality and Social Psychology, Inc.

Advanced thermopower wave in novel ZnO nanostructures/fuel composite.

PubMed

Lee, Kang Yeol; Hwang, Hayoung; Choi, Wonjoon

2014-09-10

Thermopower wave is a new concept of energy conversion from chemical to thermal to electrical energy, produced from the chemical reaction in well-designed hybrid structures between nanomaterials and combustible fuels. The enhancement and optimization of energy generation is essential to make it useful for future applications. In this study, we demonstrate that simple solution-based synthesized zinc oxide (ZnO) nanostructures, such as nanorods and nanoparticles are capable of generating high output voltage from thermopower waves. In particular, an astonishing improvement in the output voltage (up to 3 V; average 2.3 V) was achieved in a ZnO nanorods-based composite film with a solid fuel (collodion, 5% nitrocellulose), which generated an exothermic chemical reaction. Detailed analyses of thermopower waves in ZnO nanorods- and cube-like nanoparticles-based hybrid composites have been reported in which nanostructures, output voltage profile, wave propagation velocities, and surface temperature have been characterized. The average combustion velocities for a ZnO nanorods/fuel and a ZnO cube-like nanoparticles/fuel composites were 40.3 and 30.0 mm/s, while the average output voltages for these composites were 2.3 and 1.73 V. The high output voltage was attributed to the amplified temperature in intermixed composite of ZnO nanostructures and fuel due to the confined diffusive heat transfer in nanostructures. Moreover, the extended interfacial areas between ZnO nanorods and fuel induced large amplification in the dynamic change of the chemical potential, and it resulted in the enhanced output voltage. The differences of reaction velocity and the output voltage between ZnO nanorods- and ZnO cube-like nanoparticles-based composites were attributed to variations in electron mobility and grain boundary, as well as thermal conductivities of ZnO nanorods and particles. Understanding this astonishing increase and the variation of the output voltage and reaction velocity, precise ZnO nanostructures, will help in formulating specific strategies for obtaining enhanced energy generation from thermopower waves.

Determination of the chemical properties of residues retained in individual cloud droplets by XRF microprobe at SPring-8

To determine the chemical properties of residue retained in individual cloud droplets is primarily important for the understanding of rainout mechanism and aerosol modification in droplet. The sampling of individual cloud droplets were carried out on the summit of Mt. Taiko located in Tango peninsula, Kyoto prefecture, during Asian dust storm event in March of 2002. XRF microprobe system equipped at SPring-8, BL-37XU was applied to the subsequent quantification analysis of ultra trace elements in residues of individual cloud droplets. It was possible to form the replicas of separated individual cloud droplets on the thin collodion film. The two dimensional XRF maps for the residues in individual cloud droplets were clearly drawn by scanning of micro-beam. Also, XRF spectra of trace elements in residues were well resolved. From the XRF spectra for individual residues, the chemical mixed state of residues could be assumed. The chemical forms of Fe (Fe +++) and Zn (Zn +) could be clearly characterized by their K-edge micro-XANES spectra. By comparison of Z/Si mass ratios of residues in cloud droplets and those of the original sands collected in desert areas in China, the aging of ambient dust particles and their in cloud modification were indirectly assumed.

Thinspiration: Self-Improvement Versus Self-Evaluation Social Comparisons with Thin-Ideal Media Portrayals.

2015-01-01

Much research has demonstrated negative impacts of idealized-body imagery exposure on body satisfaction. Yet, paradoxically, media with such imagery attract mass audiences. Few studies showed women's body satisfaction increased due to thin-ideal exposure. The kind of social comparison women engage in (self-evaluation vs. self-improvement) may explain these inconsistent findings and the paradoxical attraction to thin-ideal messages. Across 5 days, thin-ideal messages were presented to 51 women; self-evaluation and self-improvement social comparisons as well as body satisfaction were measured each day. A linear positive change in body satisfaction emerged. Greater self-improvement social comparisons increased this change, whereas greater self-evaluation social comparisons reduced it. Extent of both social comparison types changed during the prolonged exposure. A greater tendency to compare one's body with others' improved body satisfaction through self-improvement social comparisons and fostered weight-loss behaviors through self-evaluation social comparisons.

Lamin B receptor regulates the growth and maturation of myeloid progenitors via its sterol reductase domain: implications for cholesterol biosynthesis in regulating myelopoiesis.

Lamin B receptor (LBR) is a bifunctional nuclear membrane protein with N-terminal lamin B and chromatin-binding domains plus a C-terminal sterol Δ(14) reductase domain. LBR expression increases during neutrophil differentiation, and deficient expression disrupts neutrophil nuclear lobulation characteristic of Pelger-Huët anomaly. Thus, LBR plays a critical role in regulating myeloid differentiation, but how the two functional domains of LBR support this role is currently unclear. We previously identified abnormal proliferation and deficient functional maturation of promyelocytes (erythroid, myeloid, and lymphoid [EML]-derived promyelocytes) derived from EML-ic/ic cells, a myeloid model of ichthyosis (ic) bone marrow that lacks Lbr expression. In this study, we provide new evidence that cholesterol biosynthesis is important to myeloid cell growth and is supported by the sterol reductase domain of Lbr. Cholesterol biosynthesis inhibitors caused growth inhibition of EML cells that increased in EML-derived promyelocytes, whereas cells lacking Lbr exhibited complete growth arrest at both stages. Lipid production increased during wild-type neutrophil maturation, but ic/ic cells exhibited deficient levels of lipid and cholesterol production. Ectopic expression of a full-length Lbr in EML-ic/ic cells rescued both nuclear lobulation and growth arrest in cholesterol starvation conditions. Lipid production also was rescued, and a deficient respiratory burst was corrected. Expression of just the C-terminal sterol reductase domain of Lbr in ic/ic cells also improved each of these phenotypes. Our data support the conclusion that the sterol Δ(14) reductase domain of LBR plays a critical role in cholesterol biosynthesis and that this process is essential to both myeloid cell growth and functional maturation.

Lamin B receptor (LBR) is a bifunctional nuclear membrane protein with N-terminal lamin B and chromatin binding domains plus a C-terminal sterol Δ14 reductase domain. LBR expression increases during neutrophil differentiation and deficient expression disrupts neutrophil nuclear lobulation characteristic of Pelger-Huët anomaly. Thus LBR plays a critical role in regulating myeloid differentiation, but how the two functional domains of LBR support this role is currently unclear. We previously identified abnormal proliferation and deficient functional maturation of promyelocytes (EPRO cells) derived from EML-ic/ic cells, a myeloid model of ichthyosis (ic) bone marrow that lacks Lbr expression. Here we provide new evidence that cholesterol biosynthesis is important to myeloid cell growth and is supported by the sterol reductase domain of Lbr. Cholesterol biosynthesis inhibitors caused growth inhibition of EML cells that increased in EPRO cells, whereas cells lacking Lbr exhibited complete growth arrest at both stages. Lipid production increased during wild-type neutrophil maturation, but ic/ic cells exhibited deficient levels of lipid and cholesterol production. Ectopic expression of a full length Lbr in EML-ic/ic cells rescued both nuclear lobulation and growth arrest in cholesterol starvation conditions. Lipid production also was rescued, and a deficient respiratory burst was corrected.

This research tested whether and how partners' support of self-improvement efforts influences recipients' relationship evaluations and self-improvement success. Study 1 provided an initial test of predictions using self-reports (N = 150). Study 2 assessed support behavior exhibited in couples' (N = 47) discussions of self-improvement desires, and tracked relationship quality and self-improvement every 3 months for 1 year. More nurturing and action-facilitating partner support was more helpful to recipients, whereas partners who criticized and invalidated recipients were less helpful. Receiving more help from the partner, in turn, predicted greater relationship quality and more self-improvement. More negative support seeking also predicted lower self-improvement because recipients' behavior elicited less partner help. These effects were not attributable to partners' general warmth and understanding, global self or relationship evaluations, how much recipients desired or tried to change, or whether targeted attributes posed relationship problems. This research documents the powerful influence that partners' help has on recipients' personal growth.

Mutations of filaggrin gene (FLG) have been identified as the cause of ichthyosis vulgaris, while recently FLG mutations were found to be associated with gastric cancer. This study aimed to investigate the association of filaggrin polymorphism with Epstein-Barr virus-associated tumors in China. A total of 200 patients with three types of tumors and 117 normal control samples were genotyped at three common FLG mutation loci (rs3126085, K4671X, R501X) by using Sequenom MassARRAY technique. The χ 2 test was used to evaluate the relationship between the mutation and the three kinds of tumors. A two-sided P value of <0.05 was considered statistically significant. The results showed that two single-nucleotide polymorphism (SNP) loci (rs3126085, K4671X) were significantly associated with nasopharyngeal carcinoma in genetic model. In addition, the two SNPs K4671X and rs3126085 were related to Epstein-Barr virus (EBV)-associated gastric carcinoma (EBVaGC) and EBV-negative gastric carcinoma (EBVnGC), respectively. Furthermore, allele distributions in EBVaGC and EBVnGC were verified to be different in both SNP loci.

Revertant mosaicism in heritable skin diseases: mechanisms of natural gene therapy.

2012-09-01

Revertant mosaicism (RM) refers to the co-existence of cells carrying disease-causing mutations with cells in which the inherited mutation is genetically corrected by a spontaneous event. It has been discovered in an increasing number of heritable skin diseases: ichthyosis with confetti and different subtypes of epidermolysis bullosa. This "natural gene therapy" phenomenon manifests as normal appearing skin areas surrounded by affected skin. Although initially thought to be rare, RM is now considered relatively common in genetic skin diseases. To address the issues relevant to RM, we here discuss the following questions: 1) What is the incidence of RM in heritable skin diseases? 2) What are the repair mechanisms in RM? 3) When do the revertant mutations occur? 4) How do you recognize revertant skin? 5) Do the areas of RM change in size? The answers to these questions allow us to acquire knowledge on these reverted cells, the mechanisms of RM, and utility of the reverted cells to the advantage of the patient. The revertant skin could potentially be used to treat the patient's own affected skin.

The Regulation of Steroid Action by Sulfation and Desulfation

Mueller, Jonathan W.; Gilligan, Lorna C.; Idkowiak, Jan; Arlt, Wiebke

2015-01-01

Steroid sulfation and desulfation are fundamental pathways vital for a functional vertebrate endocrine system. After biosynthesis, hydrophobic steroids are sulfated to expedite circulatory transit. Target cells express transmembrane organic anion-transporting polypeptides that facilitate cellular uptake of sulfated steroids. Once intracellular, sulfatases hydrolyze these steroid sulfate esters to their unconjugated, and usually active, forms. Because most steroids can be sulfated, including cholesterol, pregnenolone, dehydroepiandrosterone, and estrone, understanding the function, tissue distribution, and regulation of sulfation and desulfation processes provides significant insights into normal endocrine function. Not surprisingly, dysregulation of these pathways is associated with numerous pathologies, including steroid-dependent cancers, polycystic ovary syndrome, and X-linked ichthyosis. Here we provide a comprehensive examination of our current knowledge of endocrine-related sulfation and desulfation pathways. We describe the interplay between sulfatases and sulfotransferases, showing how their expression and regulation influences steroid action. Furthermore, we address the role that organic anion-transporting polypeptides play in regulating intracellular steroid concentrations and how their expression patterns influence many pathologies, especially cancer. Finally, the recent advances in pharmacologically targeting steroidogenic pathways will be examined. PMID:26213785

Symptom fluctuations, self-esteem, and cohesion during group cognitive behaviour therapy for early psychosis.

2018-03-01

Group cohesion has been linked to positive changes in self-esteem and in symptoms during group psychotherapy in people with psychosis. These changes may be linked to changes in symptoms as fluctuations in self-esteem have been linked to symptom fluctuations. We aimed to determine the relationship between these three factors - group cohesion, self-esteem, and symptoms - during group cognitive behaviour therapy for psychosis (GCBTp). We hypothesized that group cohesion would precede changes in symptoms and self-esteem and that improvements in self-esteem would precede improvements in symptoms. This is an uncontrolled longitudinal study recruiting from a convenience sample within two early psychosis clinics. Sixty-six individuals from first episode of psychosis treatment programmes participated in this study and received 24 sessions of a validated GCBTp protocol. Participants answered a brief questionnaire at the end of each session, measuring their group cohesion, self-esteem, and perception of their symptoms as worse, same, or better than usual. Orthogonal polynomial contrasts for time effects were estimated with a mixed model for repeated measures with a random cluster effect and revealed a quartic trend regarding changes in symptoms over the 24 sessions. Self-esteem, symptoms, and group cohesion were strongly linked during a given session. Also, self-esteem changes predicted changes in symptoms up to two sessions later, and symptoms changes predicted self-esteem changes at the next session. Group cohesion preceded improvements in both self-esteem and symptoms; self-esteem also predicted improvements in group cohesion. These results suggest that self-esteem and symptoms influence each other during therapy, with improvements in one leading to improvements in the other. Group cohesion also appears to be an essential prerequisite to positive changes in self-esteem and symptoms during GCBTp. This study emphasizes the interrelation between self-esteem improvements and symptom improvements, with improvements in one leading to improvements in the other, during group CBT for psychosis. Group cohesion, in this study, is a predictor of self-esteem and symptom improvements, suggesting that a special attention should be given to developing a strong alliance and group cohesion early on during CBT for psychosis. © 2017 The British Psychological Society.

Exercise program-induced mood improvement and improved eating in severely obese adults.

PubMed

Annesi, James J; Tennant, Gisèle A

Using a practical setting, this study aimed to test exercise and nutrition interventions' effects on negative mood, self-regulation, and self-efficacy to control eating; and to assess the ability of mood change to predict changes in eating behavior, while accounting for changes in self-regulation and self-efficacy. Severely obese adults participated in a cognitive-behavioral exercise support treatment paired with either nutrition education (n = 140) or cognitive-behavioral methods applied to improved eating (n = 146). They were assessed on measures of overall negative mood, self-regulatory skill usage, self-efficacy to control eating when negative moods are present, and fruit and vegetable consumption at baseline and Week 26. Significant improvements in each psychosocial variable and fruit and vegetable intake were found. Improved mood significantly predicted fruit and vegetable consumption change, R2 = 0.12, P < 0.001. Entry of changes in self-regulation and self-efficacy into the multiple regression equation significantly strengthened the variance explained, R2 = 0.18, P < 0.001. Findings suggest that exercise-induced improvements in mood improve eating behaviors, with increases in self-regulation and self-efficacy adding to this effect.

Elemental and Isotopic Analysis of Uranium Oxide an NIST Glass Standards by FEMTOSECOND-LA-ICP-MIC-MS

The objective of this work was to test and demonstrate the analytical figures of merit of a femtosecond-laser ablation (fs-LA) system coupled with an inductively coupled plasma-multi-ion collector-mass spectrometer (ICP-MIC-MS). The mobile fs-LA sampling system was designed and assembled at Ames Laboratory and shipped to Oak Ridge National Laboratory (ORNL), where it was integrated with an ICP-MIC-MS. The test period of the integrated systems was February 2-6, 2009. Spatially-resolved analysis of particulate samples is accomplished by 100-shot laser ablation using a fs-pulsewidth laser and monitoring selected isotopes in the resulting ICP-MS transient signal. The capability of performing high sensitivity, spatiallymore » resolved, isotopic analyses with high accuracy and precision and with virtually no sample preparation makes fs-LA-ICP-MIC-MS valuable for the measurement of actinide isotopes at low concentrations in very small samples for nonproliferation purposes. Femtosecond-LA has been shown to generate particles from the sample that are more representative of the bulk composition, thereby minimizing weaknesses encountered in previous work using nanosecond-LA (ns-LA). The improvement of fs- over ns-LA sampling arises from the different mechanisms for transfer of energy into the sample in these two laser pulse-length regimes. The shorter duration fs-LA pulses induce less heating and cause less damage to the sample than the longer ns pulses. This results in better stoichiometric sampling (i.e., a closer correlation between the composition of the ablated particles and that of the original solid sample), which improves accuracy for both intra- and inter-elemental analysis. The primary samples analyzed in this work are (a) solid uranium oxide powdered samples having different {sup 235}U to {sup 238}U concentration ratios, and (b) glass reference materials (NIST 610, 612, 614, and 616). Solid uranium oxide samples containing {sup 235}U in depleted, natural, and enriched abundances were analyzed as particle aggregates immobilized in a collodion substrate. The uranium oxide samples were nuclear reference materials (CRMs U0002, U005-A, 129-A, U015, U030-A, and U050) obtained from New Brunswick Laboratory-USDOE.« less

Relationship of Initial Self-Regulatory Ability with Changes in Self-Regulation and Associated Fruit and Vegetable Consumption in Severely Obese Women Initiating an Exercise and Nutrition Treatment: Moderation of Mood and Self-Efficacy

2011-01-01

An emphasis on increasing self-regulation is an alternate to nutrition education, which has had poor results in the behavioral treatment of obesity. Although appropriately designed weight-loss treatments may enhance one’s self-regulatory ability to control eating, whether improvements are moderated by psychosocial factors such as initial self-regulatory skills use, self-efficacy to control eating, and mood is unknown. Severely obese women (BMI 35-50 kg·m-2) were randomized into 26-week treatments of exercise supported by cognitive-behavioral methods paired with either nutrition education (n = 114) or cognitive-behavioral methods applied to controlled eating (n = 121). Improvement in self-regulation for controlled eating was 36.9% greater (p < 0.01) for the group incorporating cognitive-behavioral methods for controlled eating. Change in self-regulation was significantly associated with self-regulation at baseline (β = -0.33). Both mood and self-efficacy for controlled eating significantly moderated this relationship. Increased self-regulation was associated with both increases in fruit and vegetable consumption and fruit and vegetable intake at treatment end. The present findings increase our understanding of psychosocial variables associated with increased self-regulatory skills usage and improvements in eating that, after replication, may be used to improve the effects of behavioral weight-loss treatments. Key points Initial self-regulatory abilities do not appear to affect improvements in self-regulation for eating, however direct training in behavioral skills are predictors of change. The relationship of self-regulation improvements and improved eating is significant, and affected by mood and self-efficacy in women with obesity. Instruction in behavioral skills such as cognitive restructuring and relapse prevention is associated with better improvements in eating than typical methods of nutrition education. Cognitive-behavioral methods for exercise may be paired with cognitive-behavioral methods for eating to maximize longer-term effects on eating behaviors. PMID:24149553

Changes in self-efficacy for exercise and improved nutrition fostered by increased self-regulation among adults with obesity.

Behavioral theory suggests that treatments that increase participants' use of self-regulatory skills and/or their feelings of ability (self-efficacy) will improve exercise and nutrition behaviors. In addition, psychosocial factors associated with increased exercise may carry over to improved eating. Self-regulation might enhance self-efficacy through feelings of ability to manage barriers to maintaining weight-loss behaviors. Sedentary adults with severe or morbid obesity (M age = 43 years; M BMI = 40.1 kg/m(2)) participated in a 6-month study within a community-based YMCA center. We randomly assigned participants to one of the two groups that incorporated the same cognitive-behavioral support of exercise paired with methods for controlled, healthy eating emphasizing either (a) self-efficacy (n = 138), or (b) self-regulation (n = 136) methods. Mixed model repeated measures ANOVAs indicated significant improvements in exercise- and eating-related self-regulation over 3 months, and exercise- and eating-related self-efficacy over 6 months. The Self-Regulation Treatment Group demonstrated greater improvements in self-regulation for eating and fruit and vegetable intake than the Self-Efficacy Group. Regression analyses indicated that for both exercise and eating, self-regulation change significantly predicted self-efficacy change. In separate equations, changes in exercise and fruit and vegetable intake mediated those relationships, and change in self-efficacy and the corresponding behavioral changes demonstrated reciprocal, mutually reinforcing, relationships. There was evidence of carry-over, or generalization, of both self-regulation and self-efficacy changes from an exercise context to an eating context. We discussed findings in terms of leveraging self-regulation to improve self-efficacy, and provide a rationale for why exercise is the strongest predictor of success with weight loss. Results may be used to inform future behavioral weight-management treatments through improved knowledge of relationships among theoretically derived psychosocial factors.

Asian dust storm particles can affect precipitation composition because they are either incorporated into cloud via condensation of water vapour (nucleation) or due to the uptake of particles by existing droplets. And subsequently they affect aquatic and terrestrial ecosystems. In order to study the intercorrelation between the chemical natures of both the particles collected at ground-based site and those scavenged as CCN, the intensive field measurement was carried out on west coast of Japan (Yasaka, Tango Peninsula, 35.62°N; 135.07°E) during dense Asian dust storm event on March 22, 2002. Due to the size dependence of the chemical composition of aerosol particle, size-segregated aerosol particles were collect using Low pressure Andersen impactor sampler. Also, to collect cloud droplets individually, a particular method for the cloud droplet replication was newly applied using collodion (nitrocellulose) film. Sampling of cloud droplets was performed at summit of a mountain (680 m) in Yasaka. To analyze the ambient individual aerosol particles and individual retained particles in cloud droplet, X-ray fluorescence (XRF) analytical method set at SPring-8 on BL39XU was applied. Analytical result enables us not only to compare the characteristics of individual particles scavenged as CCN and those collected at ground-based site, but also to estimate the influence of long-range transport.

A multi-layer membrane system was used to measure in vitro release of hydrophilic macromolecules such as hyaluronic acid (HA) from semisolid formulations. One enzymatically digested HA-derivative with molecular mass of 22 kDa (HA-D) and 1200 kDa intact HA (HA) were incorporated into three semisolid formulations: water-containing hydrophilic ointment (WHO), amphiphilic cream (AC) and water-containing wool wax alcohol ointment (WWO). Because of the high hydrophilic properties of HA-D and HA, the artificial model membranes consisted of collodion as the matrix and glycerol as the hydrophilic acceptor phase. The area under the concentration-time curve and the mean dissolution time were used as a quantitative parameter to characterise the rate and extent of release in vitro. This study showed that the HA-D and HA release as hydrophilic substances from WHO was higher than both from AC and WWO. It was observed that 83% of HA-D1 was released from WHO after 2 h; in contrast, only 10% was released from 2% HA from the same vehicle during the same time. In conclusion, the in vitro availability of enzymatically digested HA-D was higher for WHO than for the other formulations, AC and WWO. Similarly, the availability of HA-D was higher than that of HA from the same formulations.

Sex difference in human fingertip recognition of micron-level randomness as unpleasant.

We investigated sex difference in evaluation, using the human fingertip, of the tactile impressions of three different micron-scale patterns laser-engraved on plastic plates. There were two ordered (periodical) patterns consisting of ripples on a scale of a few micrometres and one pseudo-random (non-periodical) pattern; these patterns were considered to mimic the surface geometry of healthy and damaged human hair, respectively. In the first experiment, 10 women and 10 men ran a fingertip over each surface and determined which of the three plates felt most unpleasant. All 10 female participants reported the random pattern, but not the ordered patterns, as unpleasant, whereas the majority of the male participants did not. In the second experiment, 9 of 10 female participants continued to report the pseudo-random pattern as unpleasant even after their fingertip had been coated with a collodion membrane. In the third experiment, participants were asked to evaluate the magnitude of the tactile impression for each pattern. The results again indicated that female participants tend to report a greater magnitude of unpleasantness than male participants. Our findings indicate that the female participants could readily detect microgeometric surface characteristics and that they evaluated the random pattern as more unpleasant. Possible physical and perceptual mechanisms involved are discussed. © 2011 The Authors. ICS © 2011 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Improved self-management skills predict improvements in quality of life and depression in patients with chronic disorders.

Self-management programs aim to improve patients' skills to manage their chronic condition in everyday life. Improvement in self-management is assumed to bring about improvements in more distal outcomes, such as quality of life. This study aimed to test the hypothesis that changes in self-reported self-management skills observed after participation in self-management programs predict changes in both quality of life and depressive symptoms three months later. Using latent change modeling, the relationship between changes in latent variables over three time points (start and end of rehabilitation, after three months) was analysed. The sample comprised 580 patients with different chronic conditions treated in inpatient rehabilitation clinics. The influence of additional predictor variables (age, sex, perceived social support) and type of disorder as a moderator variable was also tested. Changes in self-reported self-management skills after rehabilitation predicted changes in both quality of life and depressive symptoms at the end of rehabilitation and the 3 months follow-up. These relationships remained significant after the inclusion of other predictor variables and were similar across disorders. The findings provide support for the hypothesis that improvements in proximal outcomes of self-management programs may foster improvements in distal outcomes. Further studies should investigate treatment mechanisms. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Heart failure (HF) patient education aims to foster patients' self-management skills. These are assumed to bring about, in turn, improvements in distal outcomes such as quality of life. The purpose of this study was to test the hypothesis that change in self-reported self-management skills observed after participation in self-management education predicts changes in physical and mental quality of life and depressive symptoms up to one year thereafter. The sample comprised 342 patients with chronic heart failure, treated in inpatient rehabilitation clinics, who received a heart failure self-management education program. Latent change modelling was used to analyze relationships between both short-term (during inpatient rehabilitation) and intermediate-term (after six months) changes in self-reported self-management skills and both intermediate-term and long-term (after twelve months) changes in physical and mental quality of life and depressive symptoms. Short-term changes in self-reported self-management skills predicted intermediate-term changes in mental quality of life and long-term changes in physical quality of life. Intermediate-term changes in self-reported self-management skills predicted long-term changes in all outcomes. These findings support the assumption that improvements in self-management skills may foster improvements in distal outcomes.

Understanding the relationship between ethnicity and self-management is important due to disparities in healthcare access, utilization, and outcomes among adults with type 2 diabetes from different ethnic groups in the US. Self-reports of self-management and interest in improving self-management from US people with diabetes (PWD) in the 2nd Diabetes Attitudes, Wishes and Needs (DAWN2) study, a multinational, multi-stakeholder survey, were analyzed, including 447 non-Hispanic White, 241 African American, 194 Hispanic American, and 173 Chinese American PWD (>18 years). Overall, self-management behavior was highest for medication taking and lowest for physical activity. Non-Hispanic Whites had lowest physical activity and highest adherence to insulin therapy. Chinese Americans had lowest foot care and highest healthy eating. Overall, interest was highest for improving healthy eating and physical activity. Chinese Americans and Hispanic Americans were more interested than non-Hispanic Whites in improving most self-management behaviors. Chinese Americans were more interested than African Americans in improving most self-management behaviors. Healthcare providers telling PWD that their A1c needs improvement was associated with lower self-rated glucose control, which was associated with higher PWD interest in improving self-management behaviors. Diabetes care providers should use patient-centered approaches and consider ethnicity in tailoring self-management support. Copyright © 2017 The Authors. Published by Elsevier Inc.

Tremblay, Nicole; Boutin, Claude; Ladouceur, Robert

2008-12-01

The gambling industry has offered self-exclusion programs for quite a long time. Such measures are designed to limit access to gaming opportunities and provide problem gamblers with the help they need to cease or limit their gambling behaviour. However, few studies have empirically evaluated these programs. This study has three objectives: (1) to observe the participation in an improved self-exclusion program that includes an initial voluntary evaluation, phone support, and a mandatory meeting, (2) to evaluate satisfaction and usefulness of this service as perceived by self-excluders, (3) to measure the preliminary impact of this improved program. One hundred sixteen self-excluders completed a questionnaire about their satisfaction and their perception of the usefulness during the mandatory meeting. Among those participants, 39 attended an initial meeting. Comparisons between data collected at the initial meeting and data taken at the final meeting were made for those 39 participants. Data showed that gamblers chose the improved self-exclusion program 75% of the time; 25% preferred to sign a regular self-exclusion contract. Among those who chose the improved service, 40% wanted an initial voluntary evaluation and 37% of these individuals actually attended that meeting. Seventy percent of gamblers came to the mandatory meeting, which was a required condition to end their self-exclusion. The majority of participants were satisfied with the improved self-exclusion service and perceived it as useful. Major improvements were observed between the final and the initial evaluation on time and money spent, consequences of gambling, DSM-IV score, and psychological distress. The applicability of an improved self-exclusion program is discussed and, as shown in our study, the inclusion of a final mandatory meeting might not be so repulsive for self-excluders. Future research directives are also proposed.

Moderation of age, sex, and ethnicity on psychosocial predictors of increased exercise and improved eating.

2013-01-01

Although research indicates that treatment-induced improvements in self-regulation, mood, and self-efficacy significantly predict increased exercise and improved eating, moderation by participants' personal characteristics is largely unknown. Severely obese adults (N = 414; 47% White, 53% African American) volunteered for a behavioral exercise and nutrition treatment and demonstrated significant within-group improvements in self-efficacy for exercise, self-regulation for exercise, mood, self-efficacy for controlled eating, self-regulation for controlled eating, exercise volume, and fruit and vegetable intake over 26 weeks. After testing age, sex, and race/ethnicity as possible moderators of the prediction of changes in exercise volume and fruit and vegetable consumption by changes in self-regulation, mood, and self-efficacy, only age significantly moderated change in volume of exercise. Implications for theory and treatment were discussed.

Improving service user self-management: development and implementation of a strategy for the Richmond Response and Rehabilitation Team.

Community rapid response and rehabilitation teams are used to prevent avoidable hospital admissions for adults living with multiple long-term conditions and to support early hospital discharge by providing short-term intensive multidisciplinary support. Supporting self-management is an important service intervention if desired outcomes are to be achieved. A Care Quality Commission inspection of the Richmond Response and Rehabilitation Team in 2014 identified that self-management plans were not routinely developed with service users and reported this as requiring improvement. This quality improvement project aimed to develop and implement a self-management strategy for service users and for 90% of service users to have a personalised self-management plan within 3 months. The quality improvement intervention used the Plan-Do-Study-Act model comprising: (1) the development of a self-management plan, (2) staff education to support service users to self-manage using motivational interviewing techniques, (3) piloting the self-management plan with service users, (4) implementation of the self-management plan and (5) monthly audit and feedback. Evaluation involved an audit of the number and quality of self-management plans developed with service users and a survey of staff knowledge and confidence to support service users to self-manage. Following implementation of the intervention, the number of self-management plans developed in collaboration with service users increased from 0 to 187 over a 4-week period. Monthly audit data confirmed that this improvement has been sustained. Results indicated that staff knowledge and confidence improved after an education intervention. Quality improvement methods facilitated development and operationalisation of a self-management strategy by a community rapid response and rehabilitation team. The next phase of the project is to evaluate the impact of the self-management strategy on key service outcomes including self-efficacy, unplanned and emergency hospital admissions and early discharges.

In the previous research, Collaborative Problem Based Physic Learning (CPBPL) model has been developed to improve student’s science process skills, collaborative problem solving, and self-confidence on physics learning. This research is aimed to analyze the effectiveness of CPBPL model towards the improvement of student’s self-confidence on physics learning. This research implemented quasi experimental design on 140 senior high school students who were divided into 4 groups. Data collection was conducted through questionnaire, observation, and interview. Self-confidence measurement was conducted through Self-Confidence Evaluation Sheet (SCES). The data was analyzed using Wilcoxon test, n-gain, and Kruskal Wallis test. Result shows that: (1) There is a significant score improvement on student’s self-confidence on physics learning (α=5%), (2) n-gain value student’s self-confidence on physics learning is high, and (3) n-gain average student’s self-confidence on physics learning was consistent throughout all groups. It can be concluded that CPBPL model is effective to improve student’s self-confidence on physics learning.

To examine if the application of Orem's self-care model could improve self-care knowledge, attitudes, practices, and respiratory conditions of trauma patients with chest tubes, a quasi-experimental study was conducted. The participants were assigned to two groups-namely, Orem's model and routine care. Although the patients' self-care knowledge, attitudes, and practices were improved in both groups over the course of 3 days since the initial assessments, there was a greater degree of improvement in the experimental group than that in the control group. However, there were no differences in the improvement of the chest parameters between the two groups. Orem's model was effective in improving self-care in patients with chest tube.

Pulmonary rehabilitation (PR) improves functional exercise capacity and health status in people with chronic obstructive pulmonary disease (COPD), although these outcomes are often not maintained following PR. Self-efficacy is a precursor to outcomes achievement, yet few studies have examined the importance of self-efficacy to outcome improvement during PR, or how it develops over time. Further, the contribution of exercise-specific self-efficacy to outcomes in PR is unknown. The aims of this study were to determine (a) whether baseline exercise self-efficacy predicts PR attendance and change in functional exercise capacity and health status over PR, and (b) if exercise self-efficacy changes with PR. Fifty-eight out of 64 patients with COPD completed PR and assessments of exercise self-efficacy (task, coping, scheduling), the 6-minute walk test (6MWT), and St. George's Respiratory Questionnaire (SGRQ) at the beginning and end of PR. Analyses were conducted to predict attendance, and change in 6MWT and SGRQ, while controlling for baseline demographic and clinical indicators. Change in 6MWT, SGRQ, and self-efficacy with PR was also examined. Clinically significant increases in the 6MWT and SGRQ were achieved with PR. Stronger task self-efficacy predicted better attendance, while stronger coping self-efficacy predicted greater 6MWT improvement. No variables predicted SGRQ change. Scheduling self-efficacy significantly improved with PR, whereas task and coping self-efficacy did not. Baseline exercise self-efficacy appears to be a determinant of rehabilitation attendance and functional exercise improvement with PR. Clinicians should evaluate and target exercise self-efficacy to maximize adherence and health outcome improvement with PR. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Can Video Self-Modeling Improve Affected Limb Reach and Grasp Ability in Stroke Patients?

The authors examined whether feedforward video self-modeling (FF VSM) would improve control over the affected limb, movement self-confidence, movement self-consciousness, and well-being in 18 stroke survivors. Participants completed a cup transport task and 2 questionnaires related to psychological processes pre- and postintervention. Pretest video footage of the unaffected limb performing the task was edited to create a best-of or mirror-reversed training DVD, creating the illusion that patients were performing proficiently with the affected limb. The training yielded significant improvements for the forward movement of the affected limb compared to the unaffected limb. Significant improvements were also seen in movement self-confidence, movement self-consciousness, and well-being. FF VSM appears to be a viable way to improve motor ability in populations with movement disorders.

Nucleotide excision repair and human syndromes.

DNA damage is implicated in cancer and aging, and several DNA repair mechanisms exist that safeguard the genome from these deleterious consequences. Nucleotide excision repair (NER) removes a wide diversity of lesions, the main of which include UV-induced lesions, bulky chemical adducts and some forms of oxidative damage. The NER process involves the action of at least 30 proteins in a 'cut-and-paste'-like mechanism. The consequences of a defect in one of the NER proteins are apparent from three rare recessive syndromes: xeroderma pigmentosum (XP), Cockayne syndrome (CS) and the photosensitive form of the brittle hair disorder trichothiodystrophy (TTD). Sun-sensitive skin is associated with skin cancer predisposition in the case of XP, but remarkably not in CS and TTD. Moreover, the spectrum of clinical symptoms differs considerably between the three syndromes. CS and TTD patients exhibit a spectrum of neurodevelopmental abnormalities and, in addition, TTD is associated with ichthyosis and brittle hair. These typical CS and TTD abnormalities are difficult to comprehend as a consequence of defective NER. This review briefly describes the biochemistry of the NER process, summarizes the clinical features of the NER disorders and speculates on the molecular basis underlying these pleitropic syndromes.

Mutations in PNPLA1 have been identified as causative for autosomal recessive congenital ichthyosis in humans and dogs. So far, the underlying molecular mechanisms are unknown. In this study, we generated and characterized PNPLA1-deficient mice and found that PNPLA1 is crucial for epidermal sphingolipid synthesis. The absence of functional PNPLA1 in mice impaired the formation of omega-O-acylceramides and led to an accumulation of nonesterified omega-hydroxy-ceramides. As a consequence, PNPLA1-deficient mice lacked a functional corneocyte-bound lipid envelope leading to a severe skin barrier defect and premature death of newborn animals. Functional analyses of differentiated keratinocytes from a patient with mutated PNPLA1 demonstrated an identical defect in omega-O-acylceramide synthesis in human cells, indicating that PNPLA1 function is conserved among mammals and indispensable for normal skin physiology. Notably, topical application of epidermal lipids from wild-type onto Pnpla1-mutant mice promoted rebuilding of the corneocyte-bound lipid envelope, indicating that supplementation of ichthyotic skin with omega-O-acylceramides might be a therapeutic approach for the treatment of skin symptoms in individuals affected by omega-O-acylceramide deficiency.

Keratitis-ichthyosis-deafness (KID) syndrome (OMIM 148210) is a rare ectodermal dysplasia syndrome characterized by vascularizing keratitis, congenital profound sensorineural hearing loss, and progressive erythrokeratoderma. We have found a 148G-A transition in the GJB2 gene, resulting in an asp50-to-asn (D50N) substitution in a girl with congenital deafness. This finding allowed us to diagnose а KID syndrome. But clinical features were uncommon because of a mild skin manifestation, lack of keratitis and unusual appearance resembling Clouston syndrome. Molecular genetic tests showed that it was de novo mutation because parents have normal genotype. Several autosomal dominant mutations in the GJB2 gene (сonnexin 26) now established to underlie many of the affected cases, with the majority of patients harboring the p.D50N mutation. Skin disease-associated mutation of connexin proteins can cause functional disturbances in gap junction intercellular conductance. It is likely that multiple disease mechanisms are involved across the wide spectrum of hereditary diseases relating to connexin proteins. The clinical data may provide additional insights into the dysregulation mechanisms of mutations result in the disease. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Keratin 1 (KRT1) and its heterodimer partner keratin 10 (KRT10) are major constituents of the intermediate filament cytoskeleton in suprabasal epidermis. KRT1 mutations cause epidermolytic ichthyosis in humans, characterized by loss of barrier integrity and recurrent erythema. In search of the largely unknown pathomechanisms and the role of keratins in barrier formation and inflammation control, we show here that Krt1 is crucial for maintenance of skin integrity and participates in an inflammatory network in murine keratinocytes. Absence of Krt1 caused a prenatal increase in interleukin-18 (IL-18) and the S100A8 and S100A9 proteins, accompanied by a barrier defect and perinatal lethality. Depletion of IL-18 partially rescued Krt1(-/-) mice. IL-18 release was keratinocyte-autonomous, KRT1 and caspase-1 dependent, supporting an upstream role of KRT1 in the pathology. Finally, transcriptome profiling revealed a Krt1-mediated gene expression signature similar to atopic eczema and psoriasis, but different from Krt5 deficiency and epidermolysis bullosa simplex. Our data suggest a functional link between KRT1 and human inflammatory skin diseases.

Human skin diseases are various and induce chronic inflammatory disorders, including psoriasis, atopic dermatitis and certain forms of ichthyosis. Psoriasis is a chronic inflammatory skin disease characterized by circumscribed, red, thickened plaques. Regulation of the balance between growth, differentiation and death is critical to keratinocytes; when altered, epidermal keratinocytes undergo hyperproliferation, abnormal differentiation and inflammatory infiltration. In the present study, we focused on the effects of resveratrol, found in red wine and peanuts, on the cell death of keratinocytes. We additionally studied the mechanism of resveratrol on Sirt1, a class III histone deacetylase, and Akt phosphorylation. Resveratrol caused apoptosis and increased Sirt1 expression in human HaCaT keratinocytes, following a decrease in the p62 protein level. Inhibition of Sirt1 by Sirt1 inhibitor restored cell viability and protein levels. Furthermore, we showed that resveratrol-induced Sirt1 blocked Akt phosphorylation. The present results indicated that resveratrol inhibited the Akt pathways by inducing Sirt1, thus leading to cell death. These data suggest that resveratrol-mediated activation of Sirt1 histone deacetylase may be a potential therapeutic target for skin diseases including psoriasis.

Feeling Better About Self After Receiving Negative Feedback: When the Sense That Ability Can Be Improved Is Activated.

Hu, Xinyi; Chen, Yinghe; Tian, Baowei

2016-01-01

Past studies suggest that managers and educators often consider negative feedback as a motivator for individuals to think about their shortcomings and improve their work, but delivering negative feedback does not always achieve desired results. The present study, based on incremental theory, employed an intervention method to activate the belief that a particular ability could be improved after negative feedback. Three experiments tested the intervention effect on negative self-relevant emotion. Study 1 indicated conveying suggestions for improving ability reduced negative self-relevant emotion after negative feedback. Study 2 tested whether activating the sense of possible improvement in the ability could reduce negative self-relevant emotion. Results indicated activating the belief that ability could be improved reduced negative self-relevant emotion after failure, but delivering emotion management information alone did not yield the same effect. Study 3 extended the results by affirming the effort participants made in doing the test, and found the affirmation reduced negative self-relevant emotion. Collectively, the findings indicated focusing on the belief that the ability could be improved in the future can reduce negative self-relevant emotion after negative feedback.

The role of self-improvement and self-evaluation motives in social comparisons with idealised female bodies in the media.

2005-09-01

This study investigates the effect of social comparisons with media models on women's body image based on either self-evaluation or self-improvement motives. Ninety-eight women, for whom appearance was a relevant comparison dimension, viewed advertisements that did, or did not, feature idealised models, after being prompted to engage in self-evaluation or self-improvement comparisons. The results indicate that, when focusing on self-evaluation, comparisons with thin models are associated with higher body-focused anxiety than viewing no model advertisements. In contrast, when focusing on self-improvement, comparisons with thin models are not associated with higher body-focused anxiety than viewing no models. Furthermore, women's general tendency to engage in social comparisons moderated the effects of self-evaluative comparisons with models, so that women who did not habitually engage in social comparisons were most strongly affected. It is suggested that motive for social comparison may explain previous inconsistencies in the experimental exposure literature and warrants more careful attention in future research.

Carry-over of self-regulation for physical activity to self-regulating eating in women with morbid obesity.

Annesi, James J; Porter, Kandice J; Johnson, Ping H

2015-01-01

Poor outcomes from behavioral treatments of severe obesity have led to a dependence on invasive medical interventions, including surgery for morbidly obese individuals. Improved methods to self-regulate eating will be required to reduce obesity. The use of self-regulation methods for completing physical activity may carry over to increased self-regulation for eating through improved feelings of competence (self-efficacy) and mood. The study recruited women (Meanage = 43 years) with morbid obesity (MeanBMI = 44 kg/m(2)) to participate in 26 weeks of cognitive-behavioral support of physical activity paired with either nutrition education (n = 51) or cognitive-behavioral nutrition (n = 51) methods. Data collected were from 2011 and 2012. Significant improvements in self-regulation for physical activity, self-regulation for eating, overall mood, and self-efficacy for eating, with greater improvement in self-regulation for eating, were observed in the cognitive-behavioral nutrition group. Changes in mood and self-efficacy for eating significantly mediated the relationship between changes in self-regulation for physical activity and self-regulation for eating. When subscales of overall mood and self-efficacy were entered into separate regression equations as mediators, the only significant mediators were vigor, and controlling eating when socially pressured and when increased cues to overeat were present.

with increasing prevalence of diabetes in older people, it is important to understand factors that affect their outcomes. The Informatics for Diabetes Education and Telemedicine (IDEATel) project is a demonstration project to evaluate the feasibility and effectiveness of telemedicine with diverse, medically underserved, older diabetes patients. Subjects were randomised to telemedicine case management or usual care. This intervention has been shown to result in improved medical outcomes and self-efficacy. Self-efficacy refers to one's belief that (s)he can successfully engage in a behaviour. Self-efficacy has been shown to relate to behaviour change and glycaemic control in middle-aged individuals, but not studied in older individuals. to assess whether (a) diabetes self-efficacy relates to the primary medical outcome of glycaemic control, and to secondary outcomes (blood pressure and cholesterol), and (b) whether, after an intervention, change in diabetes self-efficacy relates to change in these medical outcomes in a group of older, ethnically diverse individuals. three waves of longitudinal data from participants in IDEATel were analysed. diabetes self-efficacy at baseline correlated with glycaemic control, blood pressure and cholesterol. An increase in diabetes self-efficacy over time was related to an improvement in glycaemic control (P < 0.0001), but not in blood pressure and lipid levels. The intervention was significantly related to improved self-efficacy over time (P < 0.0001), and both directly (P = 0.022) and indirectly through self-efficacy (P < 0.001) to improved glycaemic control. The mediation effect of self-efficacy was also significant (P< 0.004). diabetes self-efficacy is a relevant construct for older diabetes patients. Thus, interventions that target enhanced self-efficacy may also result in improved glycaemic control.

Objective The purpose of this investigation was to examine the indirect effects of Integrative Cognitive-Affective Therapy (ICAT-BN) and Cognitive-Behavioral Therapy-Enhanced (CBT-E) on bulimia nervosa (BN) treatment outcome through three hypothesized maintenance variables: emotion regulation, self-directed behavior, and self-discrepancy. Method Eighty adults with BN were randomized to 21 sessions of ICAT-BN or CBT-E. A regression-based bootstrapping approach was used to test the indirect effects of treatment on outcome at end of treatment through emotion regulation and self-directed behavior measured at mid-treatment, as well as the indirect effects of treatment at follow-up through emotion regulation, self-directed behavior, and self-discrepancy measured at end of treatment. Results No significant differences in outcome between treatment conditions were observed, and no significant direct or indirect effects were found. Examination of the individual paths within the indirect effects models revealed comparable treatment effects. Across treatments, improvements in emotion regulation and self-directed behavior between baseline and mid-treatment predicted improvements in global eating disorder scores but not binge eating and purging frequency at end of treatment. Baseline to end of treatment improvements in emotion regulation and self-directed behavior also predicted improvements in global eating disorder scores at follow-up. Baseline to end of treatment improvements in emotion regulation predicted improvements in binge eating and baseline to end of treatment increases in positive self-directed behavior predicted improvements in purging at follow-up. Discussion These findings suggest that emotion regulation and self-directed behavior are important treatment targets and that ICAT-BN and CBT-E are comparable in modifying these psychological processes among individuals with BN.

Impaired self-control is an important symptom of addictive diseases. The average number of factors improving self-control among 117 men dependent on alcohol, other substances and pathological gamblers was 5.55 (SD=3.5). We classified strategies how to improve self-control into following groups (their ordering reflects the frequency of their use in our sample): 1. The help of others (professional treatment, self-help groups, and family), 2. Distraction and similar techniques, 3. The use of motivation, 4. Life-style changes including appropriate rest, 5. Physical activity, sports, physical work, 6. The use of environments, 7. Mastering of social and other relevant skills, 8. Relaxation based approaches, 9. Techniques working with improved self-awareness, 10. Pharmacotherapy, 11. Acknowledgement of an addictive disease and abstinence, 12. Disrupting risky behavioral patterns. To improve of self-control in addictive diseases simple techniques are appropriate because of temporarily impaired cognitive functions during craving. Frequent repetition are also important.

To validate a hypothesized model exploring the influencing pathways of empowerment perceptions, health literacy, self-efficacy, and self-care behaviors to glycosylated hemoglobin (HbA1c) levels in patients with type 2 diabetes (T2DM). Overall, 295 patients with T2DM were recruited from five endocrine clinics in Taiwan through convenience sampling. Data regarding personal characteristics, empowerment perceptions, health literacy, self-efficacy, self-care behaviors, and HbA1c levels were collected. A structural equation modeling was used to validate the hypothesized model. Significant direct pathways were determined from empowerment perceptions to health literacy, from health literacy to self-efficacy, from self-efficacy to self-care behaviors, and from self-care behaviors to HbA1c levels. The empowerment perceptions and health literacy relatively influenced self-efficacy and self-care behaviors. Self-efficacy and self-care behaviors relatively influenced glycemic control in patients with T2DM. Modifying self-care behaviors have been demonstrated to be the most essential for improving glycemic control. To improve self-care behaviors, healthcare providers should target improving self-efficacy, and enhancing health literacy can be considered to be a potential strategy for improving self-efficacy. To enhance health literacy, healthcare providers could use an empowerment approach rather than an authoritative approach that emphasizes patient compliance in managing patients with T2DM.

Liver transplantation (LT) is a viable treatment for patients with end-stage chronic liver diseases. The main aim of LT is to prolong life and improve life quality. However, although survival after LT continues to improve, some aspects of recipient's health-related quality of life such as self-management and self-efficacy have been largely ignored. A total of 124 LT recipients were included in this study. Questionnaires for general health status information and a "Self-Management Questionnaire for Liver Transplantation Recipients" modified from the Chinese version of "Chronic Disease Self-Management Program Questionnaire Code Book" were used in the survey. Data were collected by self-administered questionnaires. The overall status of self-management in LT recipients was not optimistic. The major variables affecting the self-management of LT recipients were marital status, educational level and employment. The overall status of self-efficacy in LT recipients was around the medium-level. Postoperative time and self-assessment of overall health status were found as the factors impacting on self-efficacy. The self-management behavior of LT recipients needs to be improved. The health care professionals need to offer targeted health education to individual patients, help them to establish healthy lifestyle, enhance physical activity and improve self-efficacy. The development of the multilevel and multifaceted social support system will greatly facilitate the self-management in LT patients.

2013-08-01

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

The purpose of this study was to assess the effects of surgical correction of pectus carinatum on health-related quality of life and self-esteem. Between May 2012 and May 2013, a prospective observational single-center cohort study was conducted on consecutive patients undergoing surgical correction of pectus carinatum at our institution. Patients filled in questionnaires on health-related quality of life and self-esteem before and six months after surgery. Disease-specific health-related quality of life was improved by 33% (95% CI: 23; 44%) according to responses to the Nuss Questionnaire modified for Adults. The improvement for generic mental health-related quality of life was 7% (95% CI: 3; 12%) in responses to the Short Form-36 Questionnaire. The improvement in self-esteem was 9% (95% CI: 2; 17%) as assessed with the Rosenberg Self-Esteem Scale. A Single Step Questionnaire supported the improvements in health-related quality of life and self-esteem six months postsurgery. This study confirms positive effects of surgical correction of pectus carinatum on health-related quality of life and self-esteem. Patients were to a greater extent self-satisfied about chest appearance following surgery, indicating this to be a step in the right direction toward improved body image, mental health and self-esteem.

Communication Styles of Interactive Tools for Self-Improvement.

PubMed

Niess, Jasmin; Diefenbach, Sarah

Interactive products for self-improvement (e.g., online trainings to reduce stress, fitness gadgets) have become increasingly popular among consumers and healthcare providers. In line with the idea of positive computing, these tools aim to support their users on their way to improved well-being and human flourishing. As an interdisciplinary domain, the design of self-improvement technologies requires psychological, technological, and design expertise. One needs to know how to support people in behavior change, and one needs to find ways to do this through technology design. However, as recent reviews show, the interlocking relationship between these disciplines is still improvable. Many existing technologies for self-improvement neglect psychological theory on behavior change, especially motivational factors are not sufficiently considered. To counteract this, we suggest a focus on the dialog and emerging communication between product and user, considering the self-improvement tool as an interactive coach and advisor. The present qualitative interview study (N = 18) explored the user experience of self-improvement technologies. A special focus was on the perceived dialog between tool and user, which we analyzed in terms of models from communication psychology. Our findings show that users are sensible to the way the product "speaks to them" and consider this as essential for their experience and successful change. Analysis revealed different communication styles of self-improvement tools (e.g., helpful-cooperative, rational-distanced, critical-aggressive), each linked to specific emotional consequences. These findings form one starting point for a more psychologically founded design of self-improvement technology. On a more general level, our approach aims to contribute to a better integration of psychological and technological knowledge, and in consequence, supporting users on their way to enhanced well-being.

Evidence shows self-management programs are associated with improved recovery outcomes. This article reports on the effectiveness of a new nurse-led self-efficacy-based stroke self-management program. A randomized controlled trial of participants recruited from 3 acute stroke units was conducted. The intervention group received the 4-week stroke self-management program. The control group received usual care. All participants were assessed at baseline and 8 weeks after randomization. Data were analyzed using generalized estimating equations. Outcomes included self-efficacy, outcome expectation, and satisfaction with performance of self-management behaviors. One hundred twenty-eight participants were randomized with mean age, 67.46 years (SD, 11.95); 59% men; and mean duration poststroke, 45 days (SD, 26.16). At 8 weeks of follow-up in the intention-to-treat population, the intervention group improved significantly in self-efficacy (95% confidence interval, 2.55-12.45; P <0.01), outcome expectation (95% confidence interval, 5.47-14.01; P <0.01), and satisfaction with performance of self-management behaviors (95% confidence interval, 3.38-13.87; P <0.01) compared with the control. Similar results were obtained at 8 weeks of follow-up in the per-protocol population. The stroke self-management program improved survivors' self-efficacy, outcome expectation, and satisfaction with performance of self-management behaviors. URL: http://www.clinicaltrials.gov.

Self-compassion increases self-improvement motivation.

PubMed

Breines, Juliana G; Chen, Serena

2012-09-01

Can treating oneself with compassion after making a mistake increase self-improvement motivation? In four experiments, the authors examined the hypothesis that self-compassion motivates people to improve personal weaknesses, moral transgressions, and test performance. Participants in a self-compassion condition, compared to a self-esteem control condition and either no intervention or a positive distraction control condition, expressed greater incremental beliefs about a personal weakness (Experiment 1); reported greater motivation to make amends and avoid repeating a recent moral transgression (Experiment 2); spent more time studying for a difficult test following an initial failure (Experiment 3); exhibited a preference for upward social comparison after reflecting on a personal weakness (Experiment 4); and reported greater motivation to change the weakness (Experiment 4). These findings suggest that, somewhat paradoxically, taking an accepting approach to personal failure may make people more motivated to improve themselves.

Registered nurses' self-nurturance and life and career satisfaction.

PubMed

Nemcek, Mary Ann

2007-08-01

Knowledge of factors that help nurses thrive, including satisfaction with life and self-nurturance, can be used to enhance retention of a healthy work force. This study determined whether nurses are happy or satisfied with their lives; how self-nurturing or "good to self" they are; and whether a relationship exists among self-nurturance, life satisfaction, and career satisfaction. A descriptive, correlational study of 136 registered nurses involving measures of self-nurturance and life and career satisfaction was conducted. Mean scores for life satisfaction and self-nurturance were consistent with those from studies of well adults. Self-nurturance, life satisfaction, and career satisfaction were positively correlated with each other; thus, improving one is expected to improve the others. Knowledge of the significant positive correlation among life satisfaction, self-nurturance, and career satisfaction may prove useful in improving the mental health and safety of nurses. Strategies consistent with Magnet hospital characteristics are suggested for the occupational health nurse.

To develop and test the prototype of a serious digital game for improving community-dwelling older adults' heart failure (HF) knowledge and self-management behaviors. The serious game innovatively incorporates evidence-based HF guidelines with contemporary game technology. The study included three phases: development of the game prototype, its usability assessment, and evaluation of the game's functionality. Usability testing included researchers' usability assessment, followed by research personnel's observations of participants playing the game, and participants' completion of a usability survey. Next, in a pretest-post-test design, validated instruments-the Atlanta Heart Failure Knowledge Test and the Self Care for Heart Failure Index-were used to measure improvement in HF self-management knowledge and behaviors related to HF self-maintenance, self-management, and self-efficacy, respectively. A postgame survey assessed participants' perceptions of the game. During usability testing, with seven participants, 100%, 100%, and 86% found the game easy to play, enjoyable, and helpful for learning about HF, respectively. In the subsequent functionality testing, with 19 participants, 89% found the game interesting, enjoyable, and easy to play. Playing the game resulted in a significant improvement in HF self-management knowledge, a nonsignificant improvement in self-reported behaviors related to HF self-maintenance, and no difference in HF self-efficacy scores. Participants with lower education level and age preferred games to any other medium for receiving information. It is feasible to develop a serious digital game that community-dwelling older adults with HF find both satisfying and acceptable and that can improve their self-management knowledge.

To evaluate the effects of a revised 6-week walking program for adults with arthritis, Walk With Ease (WWE), delivered in 2 formats, instructor-led group or self-directed. In an observational pre-post study design, 462 individuals with self-reported arthritis selected either a group format (n = 192) or a self-directed (n = 270) format. Performance and self-reported outcomes were assessed at baseline and at 6 weeks. Self-reported outcomes were assessed at 1 year. Adjusted mean outcome values for group and self-directed participants were determined using regression models, adjusting for covariates. At 6 weeks, significant adjusted mean improvements (P < 0.05) were seen for nearly all self-report and performance measures in both formats. Modest to moderate effect sizes (ES) were seen for disability (ES 0.16-0.23), pain, fatigue, and stiffness (ES 0.21-0.40), and helplessness (ES 0.24-0.28). The Arthritis Self-Efficacy (ASE) pain and symptom scales had modest improvements (ES 0.09-0.21). The performance measures of strength (ES 0.29-0.35), balance (ES 0.12-0.36), and walking pace (ES 0.12-0.32) all showed modest to moderate improvements. No adverse events were reported for either format. At 1 year, both formats showed modest improvement in ASE pain, but there were 5 outcomes where self-directed participants showed significant improvement, while the group participants did not. The revised WWE program decreases disability and improves arthritis symptoms, self-efficacy, and perceived control, balance, strength, and walking pace in individuals with arthritis, regardless of whether they are taking a group class or doing the program as self-directed walkers. At 1 year, some benefits are maintained, particularly among the self-directed. This is a safe, easy, and inexpensive program to promote community-based physical activity.

The prevalence of obesity and associated health complications are currently at unprecedented levels. Physical activity in this population can improve patient outcomes. Virtual reality (VR) self-modeling may improve self-efficacy and adherence to physical activity. We conducted a comparative study of 30 participants randomized to 3 versions of a 3D avatar-based VR intervention about exercise: virtual representation of the self exercising condition; virtual representation of other person exercising and control condition. Participants in the virtual representation of the self group significantly increased their levels of physical activity. The improvement in physical activity for participants in the visual representation of other person exercising was marginal. The improvement for the control group was not significant. However, the effect sizes for comparing the pre and post intervention physical activity levels were quite large for all three groups. We did not find any group difference in the improvements of physical activity levels and self-efficacy among sedentary, overweight or obese individuals.

Self-care is an integral component of successful heart failure (HF) management. Engaging patients in self-care can be challenging. Fifteen patients with HF enrolled during hospitalization received a motivational intervention designed to improve HF self-care. A mixed method, pretest posttest design was used to evaluate the proportion of patients in whom the intervention was beneficial and the mechanism of effectiveness. Participants received, on average, 3.0 +/- 1.5 home visits (median 3, mode 3, range 1-6) over a three-month period from an advanced practice nurse trained in motivational interviewing and family counseling. Quantitative and qualitative data were used to judge individual patients in whom the intervention produced a clinically significant improvement in HF self-care. Audiotaped intervention sessions were analyzed using qualitative methods to assess the mechanism of intervention effectiveness. Congruence between quantitative and qualitative judgments of improved self-care revealed that 71.4% of participants improved in self-care after receiving the intervention. Analysis of transcribed intervention sessions revealed themes of 1) communication (reflective listening, empathy); 2) making it fit (acknowledging cultural beliefs, overcoming barriers and constraints, negotiating an action plan); and, 3) bridging the transition from hospital to home (providing information, building skills, activating support resources). An intervention that incorporates the core elements of motivational interviewing may be effective in improving HF self-care, but further research is needed.

Comparison of the effects of auditory subliminal stimulation and rational-emotive therapy, separately and combined, on self-concept.

The present study investigated the effects on self-concept of Rational-Emotive Therapy and auditory subliminal stimulation (separately and in combination) on 141 undergraduate students with self-concept problems. They were randomly assigned to one of four groups receiving either Rational-Emotive Therapy, subliminal stimulation, both, or a placebo treatment. Rational-Emotive Therapy significantly improved scores on all the dependent measures (cognition, self-concept, self-esteem, anxiety), except for behavior. Results for the subliminal stimulation group were similar to those of the placebo treatment except for a significant self-concept improvement and a decline in self-concept related irrational cognitions. The combined treatment yielded results similar to those of Rational-Emotive Therapy, with tentative indications of continued improvement in irrational cognitions and self-concept from posttest to follow-up.

The wonderful apparatus of John Jacob Abel called the "artificial kidney".

Hemodialysis, which now provides life-saving therapy to millions of individuals, began as an exploratory attempt to sustain the lives of selected patients in the 1950s. That was a century after the formulation of the concept and determination of the laws governing dialysis. The first step in the translation of the laboratory principles of dialysis to living animals was the "vividiffusion" apparatus developed by John Jacob Abel (1859-1938), dubbed the "artificial kidney" in the August 11, 1913 issue of The Times of London reporting the demonstration of vividiffusion by Abel at University College. The detailed article in the January 18, 1914 of the New York Times, reproduced here, is based on the subsequent medical reports published by Abel et al. Tentative attempts of human dialysis in the decade that followed based on the vividiffusion apparatus of Abel and his materials (collodion, hirudin, and glass) met with failure and had to be abandoned. Practical dialysis became possible in the 1940s and thereafter after cellophane, heparin, and teflon became available. Abel worked in an age of great progress and experimental work in the basic sciences that laid the foundations of science-driven medicine. It was a "Heroic Age of Medicine," when medical discoveries and communicating them to the public were assuming increasing importance. This article provides the cultural, social, scientific, and medical background in which Abel worked, developed and reported his wonderful apparatus called the "artificial kidney."

Indirect effects of exercise on emotional eating through psychological predictors of weight loss in women.

PubMed

Annesi, James J; Mareno, Nicole

2015-12-01

An improved understanding of how weight-loss interventions might be tailored to improve emotional eating is required. This study aimed to assess mediation of the relationship between increased exercise and decreased emotional eating so that behavioral treatments might be optimized. After randomization, women with obesity (N = 108; mean age = 48 years) were assigned to either a previously tested treatment of manual-based self-help for nutrition and exercise plus brief phone follow-ups, or a new protocol of cognitive-behavioral methods of exercise support intended to carry-over psychological improvements to better controlled eating and weight loss. A community-based field setting was incorporated. Validated self-report measures were administered over 6 months. Significant overall improvements in exercise outputs, emotional eating, mood, and self-regulation and self-efficacy for controlled eating were found. The newly developed treatment protocol demonstrated significantly greater improvements in exercise outputs and self-regulation. In a multiple mediation analysis, changes in self-regulation, self-efficacy, and mood significantly mediated the relationship between changes in exercise and emotional eating. Changes in self-efficacy and mood were significant independent mediators. Within follow-up analyses, the substitution of emotional eating subscales that addressed specific moods, and a subscale of self-efficacy for controlled eating that addressed that factor specifically in the presence of negative emotions, yielded results generally consistent with those of the multiple mediation analysis. Results suggested a psychological pathway of exercise's association with emotional eating changes in women with obesity. Guided by the present findings, tailoring exercise support and leveraging it to induce specific psychological improvements might reduce emotional eating and improve weight-management outcomes.

The objective of this exploratory one-group pretest-posttest study was to evaluate the nature of psychological change in inward depressed psychiatric patients attending multi-disciplinary treatment, including physical activity, designed to improve mental well-being. Female depressed psychiatric patients (n = 51) were examined before and after this programme over a period of 3 months. The following psychological parameters were assessed: depression, anxiety, global self-esteem, and physical self-perceptions. Depressed patients demonstrated statistically significant improvements in depression, anxiety, global self-esteem and physical self-worth (t(50) ranging from -3.76 to 4.65, all p < 0.007; ES ranging from 0.53 to -0.65). Changes in depression and anxiety displayed a strong negative correlation with changes in global self-esteem, and those changes are independent of the initial severity of the depressive symptoms ( F(2,48) ranging from 0.03 to 0.70, n.s.). Patients with greater improvement in physical self-perceptions reported greater improvement anxious symptoms then patients who did not improve. Consequently, within the limitations of the research design it can be concluded that the programme appeared successful in improving psychological well-being in female depressed patients. Results also provide preliminary insight into the potential role of the physical self in recovery.

Effects of treatment differences on psychosocial predictors of exercise and improved eating in obese, middle-age adults.

PubMed

Annesi, James

2013-09-01

Behavioral interventions for weight-loss have been largely unsuccessful. Exercise is the strongest predictor of maintained weight loss and much of its effects may be from associated changes in psychosocial factors. Middle-aged, formerly sedentary adults with severe obesity were randomly selected to 6-month treatments of cognitive-behavioral exercise support paired with either standard nutrition education (n = 99) or nutrition change supported by cognitive-behavioral means with an emphasis on self-regulation (n = 101). Overall improvements in self-efficacy and self-regulation for both exercise and managed eating, and mood, were found, with significantly greater improvements associated with the cognitive-behavioral nutrition condition in self-regulation for eating and mood. Change scores trended toward being stronger predictors of increased exercise and fruit and vegetable intake than scores at treatment end. Multiple regression analyses indicated that significant portions of the variance in both increased volume of exercise (R2 = 0.45) and fruit and vegetable intake (R2 = 0.21) were explained by changes in self-regulatory skill usage, self-efficacy, and mood. Cognitive-behavioral methods for improved eating paired with behavioral support of exercise may improve weight loss through effects on the psychosocial factors of self-regulation, self-efficacy, and overall mood more than when standard nutrition education is incorporated.

To study the effects of the quality of life (QoL) improvement on their QoL and self-esteem. This was a random controlled clinical trial study on 123 type 2 diabetes patients admitted to the Diabetes Clinic in Imam Khomeini Hospital at Ardebil, Iran from April 2009 to June 2010. The 30-70 years old participants are afflicted with type 2 diabetes, and randomly divided into 2 groups (experimental group n=61, and control group n=62). The questionnaires were composed of sociodemographic status, Farrel & Grant, and Rosenberg's self-esteem questionnaires and the quality of life (QoL) improvement plan was codified to educate and evaluate them. A p<0.05 was considered significant. Our study showed that subjects in the experimental group had low self-esteem (13%) before QOL training, and they had moderate self-esteem after the intervention (39%), however, the control group had moderate self-esteem (62.5%) in the pre-test, and changed to low self-esteem (12.9%) in the post-test, and there was significant difference in the previous and next intervention (p<0.05). The QoL improvement had positive effects on diabetic's self-esteem, and QOL as improved may help to reduce the side effects of type 2 diabetes process.

Directionality in the Relationship of Self-regulation, Self-efficacy, and Mood Changes in Facilitating Improved Physical Activity and Nutrition Behaviors: Extending Behavioral Theory to Improve Weight-Loss Treatment Effects.

Annesi, James J; Vaughn, Linda L

2017-06-01

To improve understanding of directionality in the dynamic relationships among psychosocial predictors of behavioral changes associated with weight loss. In women with obesity participating in a new behavioral weight-loss treatment that emphasizes physical activity (n = 53; body mass index = 34.7 ± 3.3 kg/m 2 ), mediation and moderated-mediation models were fit to assess directionality in the self-efficacy-self-regulation change relationship and additional effects of mood change and its basis on fruit/vegetable intake and physical activity behaviors through month 6 and from months 6 to 24. Self-regulation was a stronger predictor of change in self-efficacy than vice versa. Mood change did not moderate the relationships significantly between changes in self-efficacy and/or self-regulation, and weight loss behavior. Emotional eating significantly changed mediated relationships between changes in mood and fruit/vegetable intake through month 6 (95% confidence interval, -0.05 to 0.00). Findings clarified relationships of self-efficacy, self-regulation, and mood in the prediction of weight loss behaviors, and informed behavioral treatments for improved outcomes.

Dental Hygiene Students' Self-Assessment of Ergonomics Utilizing Photography.

PubMed

Partido, Brian B

2017-10-01

Due to postural demands, dental professionals are at high risk for developing work-related musculoskeletal disorders (WMSDs). Dental clinicians' lack of ergonomic awareness may impede the clinical application of recommendations to improve their posture. The aim of this study was to determine whether feedback involving photography and self-assessment would improve dental hygiene students' ergonomic scores and accuracy of their ergonomic self-assessments. The study involved a randomized control design and used a convenience sample of all 32 junior-year dental hygiene students enrolled in the autumn 2016 term in The Ohio State University baccalaureate dental hygiene program. Sixteen students were randomly assigned to each of two groups (control and training). At weeks one and four, all participants were photographed and completed ergonomic self-evaluations using the Modified-Dental Operator Posture Assessment Instrument (M-DOPAI). During weeks two and three, participants in the training group were photographed again and used those photographs to complete ergonomic self-assessments. All participants' pre-training and post-training photographs were given ergonomic scores by three raters. Students' self-assessments in the control group and faculty evaluations of the training group showed significant improvement in scores over time (F(1,60)=4.25, p<0.05). In addition, the accuracy of self-assessment significantly improved for students in the training group (F(1,30)=8.29, p<0.01). In this study, dental hygiene students' self-assessments using photographs resulted in improvements in their ergonomic scores and increased accuracy of their ergonomic self-assessments. Any improvement in ergonomic score or awareness can help reduce the risks for WMSDs, especially among dental clinicians.

BACKGROUND Despite exercise is recommended as an adjunct to medication therapy in patients with heart failure (HF), non-adherence to exercise is a major problem. While improving self-efficacy is an effective way to increase physical activity, the evidence concerning the relationship between strategies to enhance self-efficacy and exercise among HF has not been systematically reviewed. The objective of this systematic review is to assess the effect of interventions to change the self-efficacy on exercise in patients with HF. METHODS A systematic database search was conducted for articles reporting exercise self-efficacy interventions. Databases such as PubMed, ProQuest, CINAHL, Scopus, and PsycINFO, and the Cochrane Library were searched with restrictions to the years 2000-June 2014. A search of relevant databases identified 10 studies. Published randomized controlled intervention studies focusing strategies to change self-efficacy to exercise adherence in HF were eligible for inclusion. In addition, studies that have applied self-efficacy-based interventions to improve exercise are discussed. RESULTS Limited published data exist evaluating the self-efficacy strategies to improve exercise in HF. Dominant strategies to improve patients’ self-efficacy were performance accomplishments, vicarious experience, verbal persuasion, emotional arousal. CONCLUSION Evidence from some trials supports the view that incorporating the theory of self-efficacy into the design of an exercise intervention is beneficial. Moreover, exercise interventions aimed at integrating the four strategies of exercise self-efficacy can have positive effects on confidence and the ability to initiate exercise and recover HF symptoms. Findings of this study suggest that a positive relationship exists between self-efficacy and initiating and maintaining exercise in HF, especially in the short-term period. PMID:25815022

To determine the relationship between poor adherence and self-efficacy or social support after a pharmacist intervention. Post-hoc analysis of data from two randomized controlled trials of physician-pharmacist collaborative interventions (6 and 9 mo, respectively) to improve blood pressure control. Eleven university-affiliated primary care clinics. Five hundred eighty-four patients (aged 21-85 yrs) with uncontrolled primary hypertension; 296 were in the intervention group and 288 were in the control group. Pharmacists provided intensified hypertension management and drug adherence counseling to patients in the intervention group. Social support and self-efficacy questionnaires were administered at baseline and end-of-study visits. Patient adherence was monitored by using the Morisky self-reported adherence questionnaire. Self-reported adherence scores improved significantly in the control group (p=0.0053) but not in the intervention group; however, adherence at baseline in both groups was high. There were small, but significant, improvements in self-efficacy (p<0.04) and social support (p<0.05) scores in the intervention group but not the control group at the end of the study. Social support and, to a lesser extent, self-efficacy improved as a function of duration of study participation (9-mo vs 6-mo intervention), regardless of whether the patient received the intervention. Blood pressure control in both groups improved significantly at the end of the study; however, mean blood pressure was significantly lower in the intervention group (129.7/76.6 mm Hg) compared with the control group (140.8/78.9 mm Hg; p<0.0001 for systolic, p=0.032 for diastolic). Social support and self-efficacy improved significantly in the intervention group at the end of the pharmacist intervention. Drug adherence was correlated with self-efficacy even though drug adherence did not improve significantly in the intervention group. The fact that social support and self-efficacy improved as a function of duration of study participation suggests that participation in a research study may have had a positive influence on these measures. Even though the changes in social support, self-efficacy, and drug adherence were modest, there was significantly better blood pressure control in the intervention group compared with the control group. These findings indicate that changes in drug adherence, self-efficacy, or social support probably played a minor role in the blood pressure outcomes in these studies.

Supported exercise improves controlled eating and weight through its effects on psychosocial factors: extending a systematic research program toward treatment development.

Annesi, James J

2012-01-01

Behavioral weight-loss treatments have been overwhelmingly unsuccessful. Many inadequately address both behavioral theory and extant research--especially in regard to the lack of viability of simply educating individuals on improved eating and exercise behaviors. The aim was to synthesize research on associations of changes in exercise behaviors, psychosocial factors, eating behaviors, and weight; and then conduct further direct testing to inform the development of an improved treatment approach. A systematic program of health behavior-change research based on social cognitive theory, and extensions of that theory applied to exercise and weight loss, was first reviewed. Then, to extend this research toward treatment development and application, a field-based study of obese adults was conducted. Treatments incorporated a consistent component of cognitive-behaviorally supported exercise during 26 weeks that was paired with either standard nutrition education (n = 183) or cognitive-behavioral methods for controlled eating that emphasized self-regulatory methods such as goal setting and caloric tracking, cognitive restructuring, and eating cue awareness (n = 247). Both treatment conditions were associated with improved self-efficacy, self-regulation, mood, exercise, fruit and vegetable consumption, weight, and waist circumference; with improvements in self-regulation for eating, fruit and vegetable consumption, weight, and waist circumference significantly greater in the cognitive-behavioral nutrition condition. Changes in exercise- and eating-related self-efficacy and self-regulation were associated with changes in exercise and eating (R(2) = 0.40 and 0.17, respectively), with mood change increasing the explanatory power to R(2) = 0.43 and 0.20. Improved self-efficacy and self-regulation for exercise carried over to self-efficacy and self-regulation for controlled eating (β= 0.53 and 0.68, respectively). Development and longitudinal testing of a new and different approach to behavioral treatment for sustained weight loss that emphasizes exercise program-induced psychosocial changes preceding the facilitation of improved eating and weight loss should be guided by our present research.

Preliminary evidence suggests efficacy of yoga as add-on treatment for schizophrenia, but the underlying mechanism by which yoga improves the symptoms of schizophrenia is not completely understood. Yoga improves self-reflection in healthy individuals, and self-reflection abnormalities are typically seen in schizophrenia. However, whether yoga treatment improves impairments in self-reflection typically seen in patients with schizophrenia is not examined. This paper discusses the potential mechanism of yoga in the treatment of schizophrenia and proposes a testable hypothesis for further empirical studies. It is proposed that self-reflection abnormalities in schizophrenia improve with yoga and the neurobiological changes associated with this can be examined using empirical behavioural measures and neuroimaging measures such as magnetic resonance imaging.

A clinical nurse specialist-led intervention to enhance medication adherence using the plan-do-check-act cycle for continuous self-improvement.

PubMed

Russell, Cynthia L

2010-01-01

A clinical nurse specialist-led intervention to improve medication adherence in chronically ill adults using renal transplant recipients as an exemplar population is proposed. Meta-analyses and systematic reviews of chronically ill and transplant patients indicate that patient-specific characteristics not only are poor and inconsistent predictors for medication nonadherence but also are not amenable to intervention. Adherence has not meaningfully improved, despite meta-analyses and systematic narrative reviews of randomized controlled trials (RCTs) dealing with medication nonadherence in acutely and chronically ill persons and RCTs dealing with transplant patients. Interventions with a superior potential to enhance medication adherence must be developed. Use of a clinical nurse specialist-led continuous self-improvement intervention with adult renal transplant recipients is proposed. Continuous self-improvement focuses on improving personal systems thinking and behavior using the plan-do-check-act process. Electronic medication monitoring reports, one of several objective measures of medication adherence, are used by the clinician to provide patient feedback during the check process on medication-taking patterns. Continuous self-improvement as an intervention holds promise in supporting patient self-management and diminishing the blame that clinicians place on patients for medication nonadherence. Using an objective measure of medication adherence such as an electronic monitoring report fosters collaborative patient-clinician discussions of daily medication-taking patterns. Through collaboration, ideas for improving medication taking can be explored. Changes can be followed and evaluated for effectiveness through the continuous self-improvement process. Future studies should include RCTs comparing educational and/or behavioral interventions to improve medication adherence.

Performing and teaching appropriate follow-up of outpatient laboratory results (LRs) is a challenge. The authors tested peer-review among residents as a potentially valuable intervention. Investigators assigned residents to perform self-review (n = 27), peer-review (n = 21), or self- + peer-review (n = 30) of outpatient charts. They also compared residence performance with that of historical controls (n = 20). In September 2012, residents examined 10 LRs from April 2012 onward. A second review in November 2012 ascertained whether performing chart review improved residents' practice behaviors. Initially, the least-square (LS) mean number of LRs without documentation of follow-up per resident in the self-, peer-, and self- + peer-review group was, respectively, 0.5 (SD 1.0), 1.0 (SD 1.7), and 0.9 (SD 1.3), and post intervention, this was 1.0 (SD 0.2), 0.3 (SD 0.2), and 0.6 (SD 0.2) (self- versus peer-review P = .03). Initially the LS mean follow-up time per resident in the self-, peer-, and self- + peer-review group was, respectively, 4.2 (SD 1.2), 6.9 (SD 1.4), and 5.9 (SD 1.2) days, and after the intervention, LS mean time was 5.0 (SD 0.5), 2.5 (SD 0.6), and 3.9 (SD 0.5) days (self- versus peer-review P < .01). Self-review was not associated with significant improvements in practice. In this comparison of self- and peer-review, only residents who performed peer-review demonstrated significant improvements in their documentation practices. These findings support the use of resident peer-review in improving LR follow-up, and potentially, in other, broader resident quality improvement initiatives.

Self-perception of voice has a significant psychosocial impact on transgender persons. Research about the evolution of self-perception of voice during cross-sex hormone therapy (CSHT) is lacking. The aim of this study was to examine if self-perception of voice changes during CSHT, and if a change of serum testosterone levels as a result of CSHT can predict a change of self-perception of voice. Prospective longitudinal study. The Transsexual Voice Questionnaire (TVQ), consisting of three factors-anxiety and avoidance (AA), gender identity (GI), and voice quality (VQ)-was used. Transgender persons completed the TVQ at baseline (80 trans men and 103 trans women), after 3 and 12 months of CSHT follow-up. Trans men: From 0 to 3 months, 0 to 12 months, and 3 to 2 months of CSHT, the AA and GI scores improved. From 0 to 3 months of CSHT, the increasing testosterone level was predictive for the improvements of AA and GI scores. Trans women: From 0 to 3 months, the GI score improved. From 0 to 12 months, the AA, GI, and VQ scores improved. Improvements of self-perception of voice could not be predicted by changing serum testosterone levels. During CSHT, self-perception of voice improves in both trans men and trans women. In trans men only, the improving self-perception of voice during the first 3 months can be attributed to the CSHT. For trans women, this study supports that testosterone has acted irreversibly virializing to the voice before CSHT, if they already went through male puberty. 4.

Self-management for patients with inflammatory bowel disease in a gastroenterology ward in China: a best practice implementation project.

PubMed

Chen, Ruo-Bing

2016-11-01

Globally, there is an increasing incidence of inflammatory bowel disease. It is very important for patients to be involved with self-management that can optimize personal heath behavior to control the disease. The aim of this project was to increase nursing staff knowledge of inflammatory bowel disease discharge guidance, and to improve the quality of education for discharged patients, thereby improving their self-management. A baseline audit was conducted by interviewing 30 patients in the gastroenterology ward of Huadong Hospital, Fudan University. The project utilized the Joanna Briggs Institute's Practical Application of Clinical Evidence System and Getting Research Into Practice audit tools for promoting quality of education and self-management of patients with inflammatory bowel disease. Thirty patients were provided with written materials, which included disease education and information regarding self-management. A post-implementation audit was conducted. There was improvement of education prior to discharge and dietary consultancy in the gastroenterology ward. Self-management plans utilizing written materials only were not sufficient for ensuring sustainability of the project. Comprehensive self-management education can make a contribution to improving awareness of the importance of self-management for patients with inflammatory bowel disease.

The purpose of the study was to evaluate changes in general self-efficacy, health related quality of life (HRQoL), and stress among patients with neuroendocrine tumors (NET) following a multidisciplinary educational intervention. Forty-one patients were enrolled in this exploratory pilot study. A total of 37 patients completed the full 26-week intervention based on the principles of self-efficacy. General self-efficacy was measured by the General Self-Efficacy Scale, HRQoL was measured with the SF-36, and stress was measured with the Impact of Event Scale. Mixed effect models were used to evaluate changes in general self-efficacy, mental and physical components of HRQoL, and stress adjusting for demographic and clinical variables. Results showed significant improvements in patients' general self-efficacy (β = 0.71; P < 0.05), physical component scores of HRQoL (β = 3.09; P < 0.01), and stress (β = -2.10, P = 0.008). Findings suggest that patients with NET have the capacity to improve their ability to cope with their disease, problem-solve, improve their physical status, and reduce their stress following an educational intervention based on the principles of self-efficacy. These preliminary data provide a basis for future randomized controlled trials to test interventions to improve HRQoL for patients with NET.

The purpose of this comparative effectiveness study is to compare diabetes self-management support (DSMS) approaches and determine who can be most effective in helping patients maintain/improve clinical outcomes, self-care behaviors, distress, and satisfaction following diabetes self-management education (DSME) delivered in primary care. After receiving DSME, 141 participants were randomized to receive DSMS delivered by a trained supporter: educator, peer, practice staff, or usual education during a 6-month follow-up period. DSMS groups were compared to determine which supporter helped participants to maintain/improve A1C, blood pressure, lipids, weight, self-care, and distress. DSMS satisfaction was also examined. There was a significant improvement in A1C, empowerment, aspects of self-care, and distress following DSME at 6 weeks. Those in the educator DSMS group best sustained improved A1C while those in the other DSMS groups maintained glycemic improvements but began to show trends toward worsening. No significant differences or clear trends were seen in other clinical, behavioral, or psychosocial outcomes. The Program Reinforcement Impacts Self-Management (PRISM) study demonstrates that following DSME, participants maintained improved glycemia, lipid, weight, and self-care behaviors and reductions in distress throughout the delivery of DSMS interventions regardless of DSMS supporter. All of the participants reported satisfaction with DSMS. These findings reaffirm the critical role of educators but suggest that others may serve as DSMS supporters. Results suggest that DSME delivered in primary care is effective and multiple DSMS agents are reasonable. As patient-centered self-management approaches are being explored in primary care, delivery of DSME and DSMS becomes paramount.

The aim of this study was to determine whether the extent of improvement in self-regulation achieved between ages 4 and 6 years is associated with the level of behavioral problems later in childhood. Participants were 4-year-old children (n = 510) attending preschools in South Australia. Children's level of self-regulation was assessed using the parent-completed Devereux Early Childhood Assessment when children were aged 4, 5, and 6. Children's level of behavioral problems was assessed using total, internalizing, and externalizing scores on parent- and teacher-rated Strengths and Difficulties Questionnaires (SDQs) when children were 6 years old. Random effects regression was used to describe the changes to children's self-regulation between 4 and 6 years. Linear regression models were then used to determine the strength of the association between the extent of self-regulation improvement and level of behavioral problems. Greater improvement in self-regulation, adjusted for family characteristics and baseline self-regulation scores, was associated with lower levels of parent- (B = -3.57, 95% confidence interval [CI] [-4.49, -2.65]) and teacher-rated SDQ total difficulties scores at 6 years (B = -2.42, 95% CI [-3.50, -1.34]). These effects remained after adjustment for level of parent-rated behavioral problems at 4 years. Similar effects were found for internalizing and externalizing scores at age 6 years. The results highlight the importance of improvements in self-regulation from 4-6 years for childhood behavioral problems during the early school years. Children with lower levels of improvement in self-regulation early in life are at risk for higher levels of behavioral problems both at home and at school. (c) 2015 APA, all rights reserved).

The roles of self-efficacy and self-monitoring as proximal predictors of dental flossing frequency are studied in the context of an oral health intervention. A study among 287 university students, aged 19 to 26 years, compared an intervention group that received a brief self-regulatory treatment, with a passive and an active control group. Dental flossing, self-efficacy, and self-monitoring were assessed at baseline and 3 weeks later. The intervention led to an increase in dental flossing regardless of experimental condition. However, treatment-specific gains were documented for self-efficacy and self-monitoring. Moreover, changes in the latter two served as mediators in a path model, linking the intervention with subsequent dental flossing and yielding significant indirect effects. Self-efficacy and self-monitoring play a mediating role in facilitating dental flossing. Interventions that aim at an improvement in oral self-care should consider using these constructs. Statement of contribution What is already known on this subject? The adoption and maintenance of oral self-care can be facilitated by a number of social-cognitive variables. Interventions that include planning, action control, or self-efficacy components have been shown to improve dental flossing. In one recent study on flossing in adolescent girls, planning intervention effects were mediated by self-efficacy. What does this study add? Self-monitoring is associated with better oral self-care. A 10-min intervention improves self-efficacy and self-monitoring. Self-efficacy and self-monitoring operate as mediators between treatment and flossing. © 2014 The British Psychological Society.

Although keratosis pilaris (KP) is common, its etiopathogenesis remains unknown. KP is associated clinically with ichthyosis vulgaris and atopic dermatitis and molecular genetically with filaggrin-null mutations. In 20 KP patients and 20 matched controls, we assessed the filaggrin and claudin 1 genotypes, the phenotypes by dermatoscopy, and the morphology by light and transmission electron microscopy. Thirty-five percent of KP patients displayed filaggrin mutations, demonstrating that filaggrin mutations only partially account for the KP phenotype. Major histologic and dermatoscopic findings of KP were hyperkeratosis, hypergranulosis, mild T helper cell type 1-dominant lymphocytic inflammation, plugging of follicular orifices, striking absence of sebaceous glands, and hair shaft abnormalities in KP lesions but not in unaffected skin sites. Changes in barrier function and abnormal paracellular permeability were found in both interfollicular and follicular stratum corneum of lesional KP, which correlated ultrastructurally with impaired extracellular lamellar bilayer maturation and organization. All these features were independent of filaggrin genotype. Moreover, ultrastructure of corneodesmosomes and tight junctions appeared normal, immunohistochemistry for claudin 1 showed no reduction in protein amounts, and molecular analysis of claudin 1 was unremarkable. Our findings suggest that absence of sebaceous glands is an early step in KP pathogenesis, resulting in downstream hair shaft and epithelial barrier abnormalities. PMID:25660180

Keratosis Pilaris Revisited: Is It More Than Just a Follicular Keratosis?

PubMed Central

Thomas, Mary; Khopkar, Uday Sharadchandra

2012-01-01

Background: Keratosis pilaris (KP) is characterized by keratinous plugs in the follicular orifices and varying degrees of perifollicular erythema. The most accepted theory of its pathogenesis proposes defective keratinization of the follicular epithelium resulting in a keratotic infundibular plug. We decided to test this hypothesis by doing dermoscopy of patients diagnosed clinically as keratosis pilaris. Materials and Methods: Patients with a clinical diagnosis of KP seen between September 2011 and December 2011 were included in the study. A clinical history was obtained and examination and dermoscopic evaluation were performed on the lesions of KP. Results: The age of the patients ranged from 6-38 years. Sixteen patients had history of atopy. Nine had concomitant ichthyosis vulgaris. All the 25 patients were found to have coiled hair shafts within the affected follicular infundibula. The hair shafts were extracted with the help of a sterile needle and were found to retain their coiled nature. Perifollicular erythema was seen in 11 patients; perifollicular scaling in 9. Conclusion: Based on our observations and previously documented histological data of KP, we infer that KP may not be a disorder of keratinization, but caused by the circular hair shaft which ruptures the follicular epithelium leading to inflammation and abnormal follicular keratinization.

Middle East and North Africa (MENA) encompass very unique populations, with a rich history and encompasses characteristic ethnic, linguistic and genetic diversity. The genetic diversity of MENA region has been largely unknown. The recent availability of whole-exome and whole-genome sequences from the region has made it possible to collect population-specific allele frequencies. The integration of data sets from this region would provide insights into the landscape of genetic variants in this region. We integrated genetic variants from multiple data sets systematically, available from this region to create a compendium of over 26 million genetic variations. The variants were systematically annotated and their allele frequencies in the data sets were computed and available as a web interface which enables quick query. As a proof of principle for application of the compendium for genetic epidemiology, we analyzed the allele frequencies for variants in transglutaminase 1 (TGM1) gene, associated with autosomal recessive lamellar ichthyosis. Our analysis revealed that the carrier frequency of selected variants differed widely with significant interethnic differences. To the best of our knowledge, al mena is the first and most comprehensive repertoire of genetic variations from the Arab, Middle Eastern and North African region. We hope al mena would accelerate Precision Medicine in the region.

Fatty Aldehyde and Fatty Alcohol Metabolism: Review and Importance for Epidermal Structure and Function

PubMed Central

Rizzo, William B.

2014-01-01

Normal fatty aldehyde and alcohol metabolism is essential for epidermal differentiation and function. Long-chain aldehydes are produced by catabolism of several lipids including fatty alcohols, sphingolipids, ether glycerolipids, isoprenoid alcohols and certain aliphatic lipids that undergo α- or ω-oxidation. The fatty aldehyde generated by these pathways is chiefly metabolized to fatty acid by fatty aldehyde dehydrogenase (FALDH, alternately known as ALDH3A2), which also functions to oxidize fatty alcohols as a component of the fatty alcohol:NAD oxidoreductase (FAO) enzyme complex. Genetic deficiency of FALDH/FAO in patients with Sjögren-Larsson syndrome (SLS) results in accumulation of fatty aldehydes, fatty alcohols and related lipids (ether glycerolipids, wax esters) in cultured keratinocytes. These biochemical changes are associated with abnormalities in formation of lamellar bodies in the stratum granulosum and impaired delivery of their precursor membranes to the stratum corneum (SC). The defective extracellular SC membranes are responsible for a leaky epidermal water barrier and ichthyosis. Although lamellar bodies appear to be the pathogenic target for abnormal fatty aldehyde/alcohol metabolism in SLS, the precise biochemical mechanisms are yet to be elucidated. Nevertheless, studies in SLS highlight the critical importance of FALDH and normal fatty aldehyde/alcohol metabolism for epidermal function. PMID:24036493

The study investigated the "differential effect of role-playing enactments" hypothesis through self-evaluations of improvement in assertiveness by participants in an assertive training program. Twenty-two nonassertive Israeli students were trained in two groups: mimetic-replications (action modeling, n = 12) and spontaneous (self-produced action, n = 10) role-playing interventions. Comparisons of their scores on the Self-Expression College Scale (CSES) before and after the training showed that both groups significantly improved their self-evaluations, but the mimetic-replication group did better. In particular, this group scored significantly higher on the CSES first factor (the willingness to take risks in situations that involved other, significant persons).

Self-management is becoming an important part of treatment for patients with chronic obstructive pulmonary disease (COPD). We conducted a longitudinal survey of patients with COPD who attended a 7-week group-based lay and clinician co-delivered COPD self-management programme (SMP)to see whether they became more activated, enjoyed better health status, and quality of life, were less psychologically distressed and improved their self-management abilities. The main analysis was a per-protocol analysis (N = 131), which included only patients who attended ≥5 SMP sessions and who returned a 6-month follow-up questionnaires. Changes in the mean values of the patient outcomes were compared over time using paired t tests and general linear model for repeated measures. Patient activation significantly improved 6 months after the SMP (p < 0.001). There were also significant improvements in COPD mastery (p = 0.001) and significant improvements in a range of self-management abilities (self-monitoring and insight p = 0.03), constructive attitude shift (p = 0.04), skills and technique acquisition, (p < 0.001)). This study showed that a lay and clinician-led SMP for patients with COPD has the potential to produce improvements in important outcomes such as activation, mastery and self-management abilities. © The Author(s) 2014.

Regular exercise increases exercise self-efficacy and health-related quality of life (HRQOL); however, the mechanisms are unknown. We examined the associations of exercise adherence and physiological improvements with changes in exercise self-efficacy and HRQOL. Middle-aged adults (N = 202) were randomized to 12 months aerobic exercise (360 minutes/week) or control. Weight, waist circumference, percent body fat, cardiopulmonary fitness, HRQOL (SF-36), and exercise self-efficacy were assessed at baseline and 12 months. Adherence was measured in minutes/day from activity logs. Exercise adherence was associated with reduced bodily pain, improved general health and vitality, and reduced role-emotional scores (P(trend) ≤ 0.05). Increased fitness was associated with improved physical functioning, bodily pain and general health scores (P(trend) ≤ 0.04). Reduced weight and percent body fat were associated with improved physical functioning, general health, and bodily pain scores (P(trend) < 0.05). Decreased waist circumference was associated with improved bodily pain and general health but with reduced role-emotional scores (P(trend) ≤ 0.05). High exercise adherence, increased cardiopulmonary fitness and reduced weight, waist circumference and percent body fat were associated with increased exercise self-efficacy (P(trend) < 0.02). Monitoring adherence and tailoring exercise programs to induce changes in cardiopulmonary fitness and body composition may lead to greater improvements in HRQOL and self-efficacy that could promote exercise maintenance.

Background Regular exercise increases exercise self-efficacy and health-related quality of life (HRQOL); however, the mechanisms are unknown. We examined the associations of exercise adherence and physiological improvements with changes in exercise self-efficacy and HRQOL. Methods Middle-aged adults (N=202) were randomized to 12 months aerobic exercise (360 minutes/week) or control. Weight, waist circumference, percent body fat, cardiopulmonary fitness, HRQOL (SF-36), and exercise self-efficacy were assessed at baseline and 12 months. Adherence was measured in minutes/day from activity logs. Results Exercise adherence was associated with reduced bodily pain, improved general health and vitality, and reduced role-emotional scores (Ptrend≤0.05). Increased fitness was associated with improved physical functioning, bodily pain and general health scores (Ptrend≤0.04). Reduced weight and percent body fat were associated with improved physical functioning, general health, and bodily pain scores (Ptrend<0.05). Decreased waist circumference was associated with improved bodily pain and general health but with reduced role-emotional scores (Ptrend≤0.05). High exercise adherence, increased cardiopulmonary fitness and reduced weight, waist circumference and percent body fat were associated with increased exercise self-efficacy (Ptrend<0.02). Conclusions Monitoring adherence and tailoring exercise programs to induce changes in cardiopulmonary fitness and body composition may lead to greater improvements in HRQOL and self-efficacy that could promote exercise maintenance.

Monitoring and regulation of learning in medical education: the need for predictive cues.

PubMed

de Bruin, Anique B H; Dunlosky, John; Cavalcanti, Rodrigo B

2017-06-01

Being able to accurately monitor learning activities is a key element in self-regulated learning in all settings, including medical schools. Yet students' ability to monitor their progress is often limited, leading to inefficient use of study time. Interventions that improve the accuracy of students' monitoring can optimise self-regulated learning, leading to higher achievement. This paper reviews findings from cognitive psychology and explores potential applications in medical education, as well as areas for future research. Effective monitoring depends on students' ability to generate information ('cues') that accurately reflects their knowledge and skills. The ability of these 'cues' to predict achievement is referred to as 'cue diagnosticity'. Interventions that improve the ability of students to elicit predictive cues typically fall into two categories: (i) self-generation of cues and (ii) generation of cues that is delayed after self-study. Providing feedback and support is useful when cues are predictive but may be too complex to be readily used. Limited evidence exists about interventions to improve the accuracy of self-monitoring among medical students or trainees. Developing interventions that foster use of predictive cues can enhance the accuracy of self-monitoring, thereby improving self-study and clinical reasoning. First, insight should be gained into the characteristics of predictive cues used by medical students and trainees. Next, predictive cue prompts should be designed and tested to improve monitoring and regulation of learning. Finally, the use of predictive cues should be explored in relation to teaching and learning clinical reasoning. Improving self-regulated learning is important to help medical students and trainees efficiently acquire knowledge and skills necessary for clinical practice. Interventions that help students generate and use predictive cues hold the promise of improved self-regulated learning and achievement. This framework is applicable to learning in several areas, including the development of clinical reasoning. © 2017 The Authors Medical Education published by Association for the Study of Medical Education and John Wiley & Sons Ltd.

Change in self-esteem predicts depressive symptoms at follow-up after intensive multimodal psychotherapy for major depression.

Reduced self-esteem is a core symptom of depression, but few studies have investigated within-treatment change of self-esteem as a predictor of long-term outcome in depression. This study investigated change in self-esteem during 8 weeks of multimodal, psychodynamically oriented psychotherapy for 40 depressed patients and tested whether it would predict outcome 6 months after termination. Data was drawn from a randomized clinical pilot trial on day-clinic versus inpatient psychotherapy for depression. Findings supported the association between change in self-esteem and follow-up depression severity, even when controlling for within-treatment symptom change. Change in self-esteem was not related to overall symptoms and interpersonal problems at follow-up. Thus, change in self-esteem may be an important variable in preventing relapse for depression. Self-esteem is related to depressive symptoms and interpersonal problems. Improvement of self-esteem during psychotherapy correlates with improvements of symptoms and interpersonal problems. Change of self-esteem during psychotherapy predicts depressive symptoms 6 months after termination of therapy. When treating depressed patients, psychotherapists should work towards an improvement of self-esteem in order to prevent relapse. Copyright © 2017 John Wiley & Sons, Ltd.

Self-hypnosis was taught to 34 self-identified allergy patients who attended two training classes. They practiced on their own and were questioned two months later. Seventy-six percent of the subjects reported they felt an improvement in their symptoms; 86% of those who were medicated decreased their medicines. Practice was clearly related to reported improvement. "Feeling hypnotized" was not related to improvement.

The authors examined secondary outcomes of STRIDE, a randomized controlled trial that tested a weight-loss and lifestyle intervention for individuals taking antipsychotic medications. Hierarchical linear regression was used to explore the effects of the intervention and weight change at follow-up (six, 12, and 24 months) on body image, perceived health, and health-related self-efficacy. Participants were 200 adults who were overweight and taking antipsychotic agents. Weight change × study arm interaction was associated with significant improvement in body image from baseline to six months. From baseline to 12 months, body image scores of intervention participants improved by 1.7 points more compared with scores of control participants; greater weight loss was associated with more improvement. Between baseline and 24 months, greater weight loss was associated with improvements in body image, perceived health, and health-related self-efficacy. Participation in STRIDE improved body image, and losing weight improved perceived health and health-related self-efficacy.

Self-regulatory skills usage strengthens the relations of self-efficacy for improved eating, exercise, and weight in the severely obese: toward an explanatory model.

Lack of success with behavioral weight-management treatments indicates a need for a better understanding of modifiable psychological correlates. Adults with class 2 and 3 obesity (N = 183; Mean(BMI) = 42.0 kg/m(2)) volunteered for a 26-week nutrition and exercise treatment, based on social cognitive theory, that focused on self-efficacy and self-regulation applied to increasing cardiovascular exercise and fruit and vegetable consumption. Improved self-efficacy for controlled eating significantly predicted increased fruit and vegetable consumption (R(2) = .15). Improved self-efficacy for exercise significantly predicted increased exercise (R(2) = .46). When changes in self-regulatory skill usage were stepped into the 2 previous equations, the variances accounted for significantly increased. Increases in fruit and vegetable consumption and exercise significantly predicted weight loss (R(2) = .38). Findings suggest that behavioral theory should guide research on weight-loss treatment, and a focus on self-efficacy and self-regulatory skills applied to specific nutrition and exercise behaviors is warranted.

To develop measures of consumers' self-evaluative motives of Self-verification, Self-enhancement, and Self-improvement within the context of a mall shopping environment, an initial set of 49 items was generated by conducting three focus-group sessions. These items were subsequently converted into shopping-dependent motive statements. 250 undergraduate college students responded on a 7-point scale to each statement as these related to the acquisition of recent personal shopping goods. An exploratory factor analysis yielded five factors, accounting for 57.7% of the variance, three of which corresponded to the Self-verification motive (five items), Self-enhancement motive (three items), and Self-improvement motive (six items). These 14 items, along with 9 reconstructed items, yielded 23 items retained and subjected to additional testing. In a final round of data collection, 169 college students provided data for exploratory factor analysis. 11 items were used in confirmatory factor analysis. Analysis indicated that the 11-item scale adequately captured measures of the three self-evaluative motives. However, further data reduction produced a 9-item scale with marked improvement in statistical fit over the 11-item scale.

This longitudinal study aimed to investigate the moderating effect of health-improving workplace environment on relationships between physical activity, self-efficacy, and psychological distress. Data were collected from 16 worksites and 129 employees at two time-points. Health-improving workplace environment was measured using the Japanese version of the Environmental Assessment Tool. Physical activity, self-efficacy, and psychological distress were also measured. Multi-level structural equation modeling was used to investigate the moderating effect of health-improving workplace environment on relationships between psychological distress, self-efficacy, and physical activity. Psychological distress was negatively associated with physical activity via low self-efficacy. Physical activity was negatively related to psychological distress. Physical activity/fitness facilities in the work environment exaggerated the positive relationship between self-efficacy and physical activity. Physical activity/fitness facilities in the workplace may promote employees' physical activity.

Self-enhancing and self-improving motivations were investigated across cultures. Replicating past research, North Americans who failed on a task persisted less on a follow-up task than those who succeeded. In contrast, Japanese who failed persisted more than those who succeeded. The Japanese pattern is evidence for a self-improving orientation: Failures highlight where corrective efforts are needed. Japanese who failed also enhanced the importance and the diagnosticity of the task compared with those who succeeded, whereas North Americans did the opposite. Study 2 revealed that self-improving motivations are specific to the tasks on which one receives feedback. Study 3 unpackaged the cultural differences by demonstrating that they are due, at least in part, to divergent lay theories regarding the utility of effort. Study 4 addressed the problem of comparing cultures on subjective Likert scales and replicated the findings with a different measure.

Resident programs must assess residents' achievement of core competencies for clinical and procedural skills. Video-augmented feedback may facilitate procedural skill acquisition and promote more accurate self-assessment. A randomized controlled study to investigate whether video-augmented verbal feedback leads to increased procedural skill and improved accuracy of self-assessment compared to verbal only feedback. Participants were evaluated during procedural training for ultrasound guided internal jugular central venous catheter (US IJ CVC) placement. All participants received feedback based on a validated 30-point checklist for US IJ CVC placement and validated 6-point procedural global rating scale. Scores in both groups improved by a mean of 9.6 points (95% CI: 7.8-11.4) on the 30-point checklist, with no difference between groups in mean score improvement on the global rating scale. In regards to self-assessment, participant self-rating diverged from faculty scoring, increasingly so after receiving feedback. Residents rated highly by faculty underestimated their skill, while those rated more poorly demonstrated increasing overestimation. Accuracy of self-assessment was not improved by addition of video. While feedback advanced the skill of the resident, video-augmented feedback did not enhance skill acquisition or improve accuracy of resident self-assessment compared to standard feedback.

Stigma Related Avoidance in People Living with Severe Mental Illness (SMI): Findings of an Integrative Review.

2016-04-01

The purpose of this integrative review is to synthesize primary evidence of the impact of internalized stigma on avoidance in adult community treatment patients living with SMI. A keyword database search of articles published through 2015 yielded 21 papers and a total of 4256 patients. Our analyses found that stigmatizing beliefs associated with avoidance are related to significant loss of self-esteem. Factors generally thought to reduce stigma internalized as self-stigmatizing beliefs, such as improved insight, increased self-awareness, and psycho-education to improve stigma coping skills, do not appear to improve self-esteem.

Supported Exercise Improves Controlled Eating and Weight through Its Effects on Psychosocial Factors: Extending a Systematic Research Program Toward Treatment Development

PubMed Central

Annesi, James J

2012-01-01

Background: Behavioral weight-loss treatments have been overwhelmingly unsuccessful. Many inadequately address both behavioral theory and extant research—especially in regard to the lack of viability of simply educating individuals on improved eating and exercise behaviors. Objective: The aim was to synthesize research on associations of changes in exercise behaviors, psychosocial factors, eating behaviors, and weight; and then conduct further direct testing to inform the development of an improved treatment approach. Methods: A systematic program of health behavior-change research based on social cognitive theory, and extensions of that theory applied to exercise and weight loss, was first reviewed. Then, to extend this research toward treatment development and application, a field-based study of obese adults was conducted. Treatments incorporated a consistent component of cognitive-behaviorally supported exercise during 26 weeks that was paired with either standard nutrition education (n = 183) or cognitive-behavioral methods for controlled eating that emphasized self-regulatory methods such as goal setting and caloric tracking, cognitive restructuring, and eating cue awareness (n = 247). Results: Both treatment conditions were associated with improved self-efficacy, self-regulation, mood, exercise, fruit and vegetable consumption, weight, and waist circumference; with improvements in self-regulation for eating, fruit and vegetable consumption, weight, and waist circumference significantly greater in the cognitive-behavioral nutrition condition. Changes in exercise- and eating-related self-efficacy and self-regulation were associated with changes in exercise and eating (R2 = 0.40 and 0.17, respectively), with mood change increasing the explanatory power to R2 = 0.43 and 0.20. Improved self-efficacy and self-regulation for exercise carried over to self-efficacy and self-regulation for controlled eating (β= 0.53 and 0.68, respectively). Conclusions: Development and longitudinal testing of a new and different approach to behavioral treatment for sustained weight loss that emphasizes exercise program-induced psychosocial changes preceding the facilitation of improved eating and weight loss should be guided by our present research.

2007-12-01

The effects of social skills training on the social skills and self-esteem of 66 patients with chronic schizophrenia were evaluated using the basic training and problem-solving training models. The experimental group received 16 group training sessions, and the control group received routine nursing care. The training program consisted of two parts: conversational skills and assertiveness skills. Data were collected at pretreatment and posttreatment. The conversational, interpersonal relationship, and assertiveness skills, and self-esteem of the experimental group showed significant improvement, whereas problem-solving skills did not improve. The results indicate that training in social skills is effective for improving the social skills and self-esteem of inpatients with chronic schizophrenia.

Enhancing Self-Efficacy and Performance: An Experimental Comparison of Psychological Techniques.

Wright, Bradley James; O'Halloran, Paul Daniel; Stukas, Arthur Anthony

We assessed how 6 psychological performance enhancement techniques (PETs) differentially improved self-efficacy (SE) and skill performance. We also assessed whether vicarious experiences and verbal persuasion as posited sources of SE (Bandura, 1982 ) were supported and, further, if the effects of the 6 PETs remained after controlling for achievement motivation traits and self-esteem. A within-subject design assessed each individual across 2 trials for 3 disparate PETs. A between-groups design assessed differences between PETs paired against each other for 3 similar novel tasks. Participants (N = 96) performed 2 trials of 10 attempts at each of the tasks (kick, throw, golf putt) in a counterbalanced sequence using their nondominant limb. Participants completed the Sport Orientation Questionnaire, Rosenberg Self-Esteem Scale, and General Self-Efficacy Scale and were randomly allocated to either the modeling or imagery, goal-setting or instructional self-statement, or knowledge-of-results or motivational feedback conditions aligned with each task. An instructional self-statement improved performance better than imagery, modeling, goal setting, and motivational and knowledge-of-results augmented feedback. Motivational auditory feedback most improved SE. Increased SE change scores were related to increased performance difference scores on all tasks after controlling for age, sex, achievement motivation, and self-esteem. Some sources of SE may be more influential than others on both SE and performance improvements. We provide partial support for the sources of SE proposed by Bandura's social-cognitive theory with verbal persuasion but not vicarious experiences improving SE.

Psychosocial predictors of emotional eating and their weight-loss treatment-induced changes in women with obesity.

Annesi, James J; Mareno, Nicole; McEwen, Kristin

2016-06-01

This study aimed at assessing whether psychosocial predictors of controlled eating and weight loss also predict emotional eating, and how differing weight-loss treatment methods affect those variables. Women with obesity (M = 47.8 ± 7.9 years; BMI = 35.4 ± 3.3 kg/m(2)) were randomized into groups of either phone-supported self-help (Self-Help; n = 50) or in-person contact (Personal Contact; n = 53) intended to increase exercise, improve eating behaviors, and reduce weight over 6 months. A multiple regression analysis indicated that at baseline mood, self-regulating eating, body satisfaction, and eating-related self-efficacy significantly predicted emotional eating (R (2) = 0.35), with mood and self-efficacy as independent predictors. Improvements over 6 months on each psychosocial measure were significantly greater in the Personal Contact group. Changes in mood, self-regulation, body satisfaction, and self-efficacy significantly predicted emotional eating change (R (2) = 0.38), with all variables except self-regulation change being an independent predictor. Decreased emotional eating was significantly associated with weight loss. Findings suggest that weight-loss interventions should target specific psychosocial factors to improve emotional eating. The administration of cognitive-behavioral methods through personal contact might be more beneficial for those improvements than self-help formats.

A small-scale intervention study into narrative self-investigation in adolescent chronic fatigue syndrome (CFS). The self-confrontation method (SCM) is an instrument to assess and change personal life stories. Forty-two adolescents diagnosed with CFS were included and randomly assigned to either 6 or 12 sessions with the SCM. Twenty-five healthy adolescents were assigned to 6 sessions. Outcome was measured directly after the self-investigation procedure at 4 months. Follow-up measurements were made 10 months later. The Checklist Individual Strength and the Child Health Questionnaire were used to measure changes in fatigue, physical and psychosocial functioning. Self-investigation resulted in significant changes in participants' narratives. Moreover, after self-investigation there was a significant improvement in fatigue, physical and psychosocial functioning for the adolescents with CFS. The patients who completed 12 sessions improved most. At follow-up, the positive effects were maintained. Self-investigation enables a move beyond the symptoms of CFS in an individualized, patient centered way. Narrative transformation seems to contribute to improved physical and psychosocial outcome in adolescent CFS. The SCM allows adolescents to discover (for themselves) factors that might cause or perpetuate their fatigue. The results suggest that self-investigation is a useful instrument in the management of adolescent CFS. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

2014-11-01

The influence of simulation on self-efficacy for novice nurses has been reported inconsistently in the literature. Effect sizes across studies were synthesized using random-effects meta-analyses. Simulation improved self-efficacy in one-group, pretest-posttest studies (Hedge's g=1.21, 95% CI [0.63, 1.78]; p<0.001). Simulation also was favored over control teaching interventions in improving self-efficacy in studies with experimental designs (Hedge's g=0.27, 95% CI [0.1, 0.44]; p=0.002). In nonexperimental designs, consistent conclusions about the influence of simulation were tempered by significant between-study differences in effects. Simulation is effective at increasing self-efficacy among novice nurses, compared with traditional control groups. Copyright 2014, SLACK Incorporated.

Application of self-efficacy theory in dental clinical practice.

2010-11-01

In clinical practice, self-efficacy refers to how certain a patient feels about his or her ability to take the necessary action to improve the indicators and maintenance of health. It is assumed that the prognosis for patient behaviour can be improved by assessing the proficiency of their self-efficacy through providing psychoeducational instructions adapted for individual patients, and promoting behavioural change for self-care. Therefore, accurate assessment of self-efficacy is an important key in daily clinical preventive care. The previous research showed that the self-efficacy scale scores predicted patient behaviour in periodontal patients and mother's behaviour in paediatric dental practice. Self-efficacy belief is constructed from four principal sources of information: enactive mastery experience, vicarious experience, verbal persuasion, and physiological and affective states. Thus, self-efficacy can be enhanced by the intervention exploiting these sources. The previous studies revealed that behavioural interventions to enhance self-efficacy improved oral-care behaviour of patients. Therefore, assessment and enhancement of oral-care specific self-efficacy is important to promote behaviour modification in clinical dental practice. However, more researches are needed to evaluate the suitability of the intervention method. © 2010 John Wiley & Sons A/S.

We studied prevalence and predictors of meaningful self-reflection among surgical residents and with prompting/structured interventions, sought to improve/sustain resident skills. Residents from six programs recorded 1032 narrative self-reflective comments (120 residents), using a web-based platform. If residents identified something learned or to be improved, self-reflection was deemed meaningful. Independent variables PGY level, resident/surgeon gender, study site/Phase1: July2014-August2015 vs. Phase2: September2015-September2016) were analyzed. Meaningful self-reflection was documented in 40.6% (419/1032) of entries. PGY5's meaningfully self-reflected less than PGY1-4's, 26.1% vs. 49.6% (p = 0.002). In multivariate analysis, resident narratives during Phase 2 were 4.7 times more likely to engage in meaningful self-reflection compared to Phase1 entries (p < 0.001). Iterative changes during Phase2 showed a 236% increase in meaningful self-reflection, compared to Phase1. Surgical residents uncommonly practice meaningful self-reflection, even when prompted, and PGY5/chief residents reflect less than more junior residents. Substantial/sustained improvements in resident self-reflection can occur with both training and interventions. Copyright © 2017 Elsevier Inc. All rights reserved.

2018-05-01

This study examined the effect of family-based treatment for bulimia nervosa (FBT-BN) and cognitive behavioral therapy for adolescents (CBT-A) on depressive symptoms and self-esteem in adolescents with BN. Data were collected from 110 adolescents, ages 12-18, who met Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, text revision criteria for BN or partial BN. Participants were randomly assigned to FBT-BN or CBT-A and completed measures of depressive symptoms and self-esteem before and after treatment and at 6- and 12-month follow-up assessments. Depressive symptoms and self-esteem significantly improved in both treatments, and neither treatment appeared superior on these clinical outcomes. Parents often worry whether FBT-BN addresses comorbid depressive symptoms and low self-esteem. Our findings address this concern, as they demonstrate that FBT-BN does not differ from CBT-A in improving depressive symptoms and self-esteem, and both treatments result in symptom improvement. These findings can help clinicians guide families to choose a treatment that addresses BN and depressive symptoms and low self-esteem.

The survival of children against disaster can be seen from their confidence in their ability (self-efficacy). Self-efficacy can help children to determine their ability against disaster as preparedness. The proper intervention to increase self-efficacy as a protective factor is a therapeutic group therapy. The aim of this research is to measure the increase of self-efficacy of school age children against earthquake and Tsunami through therapeutic group therapy. This research used quasi-experimental design with pre-post-tests with control group. The sample involved in this study is 69 children, where 35 of them are in the experimental group while the rest 34 children are in the control group consisting of school children at the IV and V graders of elementary school. The result of the research showed that the self-efficacy of school children is improved significantly after being treated with therapeutic group therapy (p value < 0,05), those who were not treated with therapeutic group therapy have no significant improvement (p value > 0,05). This research is recommended to be conducted on school age children to improve their self-efficacy against disaster through health education. Copyright © 2018 Elsevier España, S.L.U.

Dairy intake by college students is markedly lower than recommendations. Interventions to improve dairy intake based on Social Cognitive Theory (SCT) have potential to successfully change behavior by improving mediators that influence dietary choices. We aimed to use SCT to improve social support, self-efficacy, outcome expectations, self-regulation, and behavior related to dairy intake in college students. We conducted a randomized nutrition education intervention. Participants included 211 college students (mean age 20.2 ± 0.1 years; 63% women and 37% men) recruited from a university campus. Participants in the intervention group (n=107) and comparison group (n=104) received an 8-week dairy intake or stress management intervention, respectively, via electronic mail. Data collection included dairy intake from 7-day food records and SCT variables from questionnaires administered during January 2008 and April 2008. Changes in dairy intake and SCT variables (ie, social support, self-efficacy, outcome expectations, and self-regulation). Multivariate analysis of covariance, with age and sex as covariates (P<0.05). Ninety-one percent of participants (n=97 intervention, n=94 comparison) provided data; complete data were analyzed for 85% of participants (n=90 intervention, n=89 comparison). Participants in the intervention group reported higher intake of total dairy foods (P=0.012) and improved use of self-regulation strategies for consuming three servings per day of total dairy (P=0.000) and low-fat dairy foods (P=0.002) following the intervention. Nutrition education via electronic mail based on an SCT model improved total dairy intake and self-regulation. Participants reported increased dairy intake and better use of self-regulation strategies. Future interventions should focus on benefits of consuming low-fat vs higher-fat dairy foods.

PubMed

Sokol, Yosef; Serper, Mark

While depression is associated with decreased self-worth, less is known about how depression relates to the degree of perceived unity of the self over time (CI; continuous identity) and appraisal of past and future selves (temporal self-appraisal). In Study 1, we examined the relationship between depression severity and temporal self-appraisal. In Study 2, we examined depression and hopelessness severity as it relates to temporal self-appraisal and continuous identity. It was hypothesized that individuals with significant levels of depressed mood would report lower self appraisals of current and future selves and that hopelessness about the future would be associated with disturbances in perception of self over time (CI; continuous identity) and temporal self-appraisal. Study 1 examined depressed mood (n=75) and non-depressed mood (n=144) individuals to determine their self-rated personal attributes for their past, present and future selves using a validated task of temporal self-appraisal. Study 2 examined an independent sample of subjects. Based on cutoff scores for clinically significant depression and hopelessness, Depressed/Hopeless (n=63) and Non-Depressed /Non-Hopeless (n=168) subjects were asked complete the validated task of temporal self-appraisal and also complete a validated task to assess their continuous identity. In Study 1, a significant difference was found between the depressed mood group and the non-depressed mood group in how they see themselves changing over time. The non-depressed group perceived themselves increasing in positive personal attributes from past, to present, to future self. The depressed mood group perceived themselves as deteriorating from the past to the present in terms of positive attributes about their self-identity. However, contrary to expectations, the depressed group perceived their future self as improved from their present self. Subjects' past and future selves were at a similar level and both were significantly higher than perception of their present self-worth. Study 2 replicated these findings and also found severity of depression was significantly related to lower levels of CI. Additionally, it was found that the severity of hopelessness was minimally associated with continuous identity and temporal self-appraisal ratings. These results suggests that even people with depressed mood have an instinctive grasp of the possibility to an improved future self-worth despite the negative cognitions associated with present self-worth and hopeless expectations about the future. While depressed and hopeless individuals may view the world negatively and feel hopeless about their general future, these results suggest that depressed individuals distinguish between hopelessness about future external success and future self-improvement. Despite perceiving their past and future selves to be more positive, depression severity was associated with less continuous identity. Since depressed individuals perceive a future self as a return to or a recovery of a past self, therapeutic strategies may focus on improving a sense of continuous identity with past and future selves and focusing on deriving meaning from current life difficulties to improve beyond a past self, growing to a superior future self. Limitations include using self-report measures of depression and hopelessness. Future studies may wish to use individuals who were diagnosed with depression to explore further how depressed people see themselves changing from the present to the future. Additionally, future studies could determine if depressed individuals who do not perceive their future self to be improved are at higher risk for adverse outcomes. Copyright © 2016 Elsevier B.V.

Self-management of asthma can now leverage new media technologies. To optimize implementation they must employ a consumer-oriented developmental approach. This study explored benefits of and barriers to improved asthma self-management and identified key elements for the development of a digital media tool to enhance asthma control. Between August 2010 and January 2011, 18 teens with asthma and 18 parent-caregivers participated in semistructured in-depth interviews to identify mechanisms for improving asthma self-management and propose characteristics for developing a digital media tool to aid such efforts. Teens and caregivers enumerated physician-recommended strategies for asthma management as well as currently employed strategies. Both groups thought of a potential digital media solution as positive, but indicated specific design requirements for such a solution to have utility. Whereas most participants perceived mobile platforms to be viable modes to improve asthma self-management, interest in having social networking capabilities was mixed. A digital media product capable of tracking conditions, triggers, and related asthma activities can be a core element of improved asthma control for youth. Improved asthma control will help decrease school absenteeism. © 2013, American School Health Association.

Self-assessment and self-directed learning are essential to becoming an effective physician. To identify factors associated with resident self-assessment on the competencies, and to determine whether residents chose areas of self-assessed relative weakness as areas for improvement in their Individualized Learning Plan (ILP). We performed a cross-sectional analysis of the American Academy of Pediatrics' PediaLink ILP database. Pediatrics residents self-assessed their competency in the 6 Accreditation Council for Graduate Medical Education competencies using a color-coded slider scale with end anchors "novice" and "proficient" (0-100), and then chose at least 1 competency to improve. Multivariate regression explored the relationship between overall confidence in core competencies, sex, level of training, and degree (MD or DO) status. Correlation examined whether residents chose to improve competencies in which they rated themselves as lower. A total of 4167 residents completed an ILP in academic year 2009-2010, with residents' ratings improving from advanced beginner (48 on a 0-100 scale) in postgraduate year-1 residents (PGY-1s) to competent (75) in PGY-3s. Residents rated themselves as most competent in professionalism (mean, 75.3) and least competent in medical knowledge (mean, 55.8) and systems-based practice (mean, 55.2). In the adjusted regression model, residents' competency ratings increased by level of training and whether they were men. In PGY-3s, there was no difference between men and women. Residents selected areas for improvement that correlated to competencies where they had rated themselves lower (P < .01). Residents' self-assessment of their competencies increased by level of training, although residents rated themselves as least competent in medical knowledge and systems-based practice, even as PGY-3s. Residents tended to choose subcompetencies, which they rated as lower to focus on improving.

Self-esteem improvement is one of the main targets of inpatient eating disorder programmes. The present study sought to examine multi-dimensional self-esteem and magnitude of change in eating psychopathology among adults participating in a specialist inpatient treatment programme for anorexia nervosa. A standardised assessment battery, including multi-dimensional measures of eating psychopathology and self-esteem, was completed pre- and post-treatment for 60 participants (all white Scottish female, mean age=25.63 years). Statistical analyses indicated that self-esteem improved with eating psychopathology and weight over the course of treatment, but that improvements were domain-specific and small in size. Global self-esteem was not predictive of treatment outcome. Dimensions of self-esteem at baseline (Lovability and Moral Self-approval), however, were predictive of magnitude of change in dimensions of eating psychopathology (Shape and Weight Concern). Magnitude of change in Self-Control and Lovability dimensions were predictive of magnitude of change in eating psychopathology (Global, Dietary Restraint, and Shape Concern). The results of this study demonstrate that the relationship between self-esteem and eating disorder is far from straightforward, and suggest that future research and interventions should focus less exclusively on self-esteem as a uni-dimensional psychological construct.

Successful weight management relies on at least two health behaviors, eating and exercise. However, little is known about their interaction on a motivational and behavioral level. Based on the Hierarchical Model of Motivation the authors examined whether exercise-specific motivation can transfer to eating regulation during a lifestyle weight control program. The authors further investigated whether general, treatment-related, and exercise motivation underlie the relation between increased exercise and improved eating regulation. Overweight/obese women participated in a 1-year randomized controlled trial (N = 239). The intervention focused on promoting physical activity and internal motivation for exercise and weight loss, following Self-Determination Theory. The control group received general health education. General and exercise specific self-determination, eating self-regulation variables, and physical activity behavior. General self-determination and more autonomous exercise motivation predicted eating self-regulation over 12 months. Additionally, general and exercise self-determination fully mediated the relation between physical activity and eating self-regulation. Increased general self-determination and exercise motivation seem to facilitate improvements in eating self-regulation during weight control in women. These motivational mechanisms also underlie the relationship between improvements in exercise behavior and eating regulation. PsycINFO Database Record (c) 2009 APA, all rights reserved.

To better understand the associations between changes in self-management behaviours and glycaemic control. We conducted a prospective observational study of 295 adult patients with Type 2 diabetes evaluated at baseline, 6 and 12 months. Four self-management behaviours were evaluated using the Summary of Diabetes Self-Care Activities instrument, which assesses healthy diet, physical activity, medication taking and self-monitoring of blood glucose. Using hierarchical linear regression models, we tested whether changes in self-management behaviours were associated with short-term (6-month) or long-term (12-month) changes in glycaemic control, after controlling for demographic and clinical characteristics. Improved diet was associated with a decrease in HbA1c level, both at 6 and 12 months. Improved medication taking was associated with short-term improvement in glycaemic control, while increased self-monitoring of blood glucose frequency was associated with a 12-month improvement in HbA1c . Completely stopping exercise after being physically active at baseline was associated with a rise in HbA1c level at 6-month follow-up. Interaction analysis indicated that a healthy diet benefitted all participant subgroups, but that medication taking was associated with glycaemic control only for participants living in poverty and more strongly for those with lower educational levels. Finally, a higher self-monitoring of blood glucose frequency was associated with better glycaemic control only in insulin-treated participants. Even after adjusting for potential confounders (including baseline HbA1c ), increased frequency of healthy diet, medication taking and self-monitoring of blood glucose were associated with improved HbA1c levels. These self-management behaviours should be regularly monitored to identify patients at risk of deterioration in glycaemic control. Barriers to optimum self-management should be removed, particularly among socio-economically disadvantaged populations. © 2015 The Authors. Diabetic Medicine © 2015 Diabetes UK.

The current study examined whether writing content related to self-enhancing (viz., downward social comparison and situational attributions) and self-improving (viz., upward social comparison and persistence) motivations were differentially related to expressive writing outcomes among 17 Asian American and 17 European American participants. Content analysis of the essays revealed no significant cultural group differences in the likelihood of engaging in self-enhancing versus self-improving reflections on negative personal experiences. However, cultural group differences were apparent in the relation between self-motivation processes and changes in anxiety and depressive symptoms at 3-month follow-up. Among European Americans, writing that reflected downward social comparison predicted positive outcomes, whereas persistence writing themes were related to poorer outcomes. For Asian Americans, writing about persistence was related to positive outcomes, whereas downward social comparison and situational attributions predicted poorer outcomes. Findings provide evidence suggesting culturally distinct mechanisms for the effects of expressive disclosure. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Self-Affirmation Improves Problem-Solving under Stress

High levels of acute and chronic stress are known to impair problem-solving and creativity on a broad range of tasks. Despite this evidence, we know little about protective factors for mitigating the deleterious effects of stress on problem-solving. Building on previous research showing that self-affirmation can buffer stress, we tested whether an experimental manipulation of self-affirmation improves problem-solving performance in chronically stressed participants. Eighty undergraduates indicated their perceived chronic stress over the previous month and were randomly assigned to either a self-affirmation or control condition. They then completed 30 difficult remote associate problem-solving items under time pressure in front of an evaluator. Results showed that self-affirmation improved problem-solving performance in underperforming chronically stressed individuals. This research suggests a novel means for boosting problem-solving under stress and may have important implications for understanding how self-affirmation boosts academic achievement in school settings.

This study evaluated improvement in self-efficacy and personal and social responsibility among at-risk of dropping-out of school adolescents participating in a program in which Hellison's Teaching Personal and Social Responsibility Model was applied in physical education classes during the course of an academic year. Thirty at-risk adolescents aged 13-14 years old (23 boys, 7 girls) were assigned to an intervention group (12 boys and 3 girls) or a comparison group (11 boys, 4 girls), the latter of which did not participate in the program. Quantitative results showed a significant improvement in the students' self-efficacy for enlisting social resources and in self-efficacy for self-regulated learning. Qualitative results showed an improvement in responsibility behaviors of participants in the intervention group. This suggests that the model could be effective for improving psychological and social development in at-risk adolescents, and that physical education classes may be an appropriate arena for working with these young people.

We tested the feasibility and acceptability of a psycho-educational self-management intervention, Managing Cancer Care: A Personal Guide (MCC), to improve knowledge of care options (curative, palliative, and hospice care) among a range of breast cancer self-management skills. We conducted a one-group, pre-post-test study among women with non-metastatic breast cancer (n = 105). We gave participants the printed, self-guided, seven-module intervention following enrollment. At baseline and 2  months, we measured knowledge of care options, desired and actual role in self-management, medical communication skills, experience and management of transitions, anxiety, depression, uncertainty, and self-efficacy. We conducted interviews to obtain module ratings and qualitative data on strengths and limitations of MCC. Knowledge of care options (δ = 0.40 (1.11), p = 0.0005) and desired role in self-management (δ = -0.28 (1.08), p = 0.0177) significantly improved. Less skilled medical communicators significantly improved their communication (δ = 3.47, standard deviation = 6.58, p = 0.0449). Multivariate modeling showed that changes in our primary outcomes of medical communication and management of transitions seemed to drive positive changes in our secondary outcomes of anxiety, depression, uncertainty, and self-efficacy. Participants highly rated MCC and reported the importance of understanding care options despite non-metastatic disease. MCC is a feasible and acceptable means of improving knowledge of care options and other aspects of breast cancer self-management. The combination of modules offered in MCC appears to have beneficial interactive effects. We are currently testing MCC more rigorously in a randomized controlled trial to explore mediating and moderating relationships. Copyright © 2015 John Wiley & Sons, Ltd.

2016-08-01

Self-regulatory speech has been shown to be important for the planning and problem solving of children. Our intervention study, including comparisons to both wait-list and typically developing controls, examined the effectiveness of a training programme designed to improve self-regulatory speech, and consequently, the planning and problem solving performance of 87 (60 males, 27 females) children aged 4-7 years with Specific Language Impairment (SLI) who were delayed in their self-regulatory speech development. The self-regulatory speech and Tower of London (TOL) performance of children with SLI who received the intervention initially or after a waiting period was compared with that of 80 (48 male, 32 female) typically developing children who did not receive any intervention. Children were tested at three time points: Time 1- prior to intervention; Time 2 - after the first SLI group had received training and the second SLI group provided a wait-list control; and Time 3 - when the second SLI group had received training. At Time 1 children with SLI produced less self-regulatory speech and were impaired on the TOL relative to the typically developing children. At Time 2, the TOL performance of children with SLI in the first training group improved significantly, whereas there was no improvement for the second training group (the wait-list group). At Time 3, the second training group improved their TOL performance and the first group maintained their performance. No significant differences in TOL performance were evident between typically developing children and those with SLI at Time 3. Moreover, decreases in social speech and increases in inaudible muttering following self-regulatory speech training were associated with improvements in TOL performance. Together, the results show that self-regulatory speech training was effective in increasing self-regulatory speech and in improving planning and problem solving performance in children with SLI.

To investigate the anatomical interaction between uncinate process and agger nasi cell to better understand the anatomy of the frontal sinus drainage pathway by endoscopy, spiral computed tomography (CT) and sectioning. Twenty-one skeletal skulls (forty-two sides) and one cadaver head (two sides) were studied by spiral CT together with endoscopy and collodion embedded thin sectioning at coronal plane. The sections with the thickness of 100 microm were stained with hemotoxylin and eosin. Under endoscopy, a leaflet of bone to the middle turbinate, which is given off by uncinate process, forms the anterior insertion of the middle turbinate onto the lateral nasal wall. The middle portion of the uncinate process attached to the frontal process of the maxilla in all of the skeletal nasal cavities, as well as the lacrimal bone in 78.6% of the skeletal nasal cavities. On CT scans, the agger nasi cell is present in 90.5% of the skeletal nasal cavities. While the lateral wall of the agger nasi cell is formed by lacrimal bone, the medial wall of the agger nasi cell is formed by uncinate process. And the anterior wall is formed by the frontal process of the maxilla. The superior portion of the uncinate process forms the medial, posterior and top wall of the agger nasi cells. The superior portion of the uncinate extends into the frontal recess and may insert into lamina papyracea (33.3%), skull base (9.5%), middle turbinate, combination of these (57.2%). The agger nasi cell is the key that unlocks the frontal recess.

Safety net systems need innovative diabetes self-management programs for linguistically diverse patients. A low-income government-sponsored managed care plan implemented a 27-week automated telephone self-management support (ATSM) / health coaching intervention for English, Spanish-, and Cantonese-speaking members from four publicly-funded clinics in a practice-based research network. Compared to waitlist, immediate intervention participants had greater 6-month improvements in overall diabetes self-care behaviors (standardized effect size [ES] 0.29, p<0.01) and SF-12 physical scores (ES 0.25, p=0.03); changes in patient-centered processes of care and cardiometabolic outcomes did not differ. ATSM is a strategy for improving patient-reported self-management and may also improve some outcomes. PMID:24594561

Self-distancing improves interpersonal perceptions and behavior by decreasing medial prefrontal cortex activity during the provision of criticism.

Previous research suggests that people show increased self-referential processing when they provide criticism to others, and that this self-referential processing can have negative effects on interpersonal perceptions and behavior. The current research hypothesized that adopting a self-distanced perspective (i.e. thinking about a situation from a non-first person point of view), as compared with a typical self-immersed perspective (i.e. thinking about a situation from a first-person point of view), would reduce self-referential processing during the provision of criticism, and in turn improve interpersonal perceptions and behavior. We tested this hypothesis in an interracial context since research suggests that self-referential processing plays a role in damaging interracial relations. White participants prepared for mentorship from a self-immersed or self-distanced perspective. They then conveyed negative and positive evaluations to a Black mentee while electroencephalogram (EEG) was recorded. Source analysis revealed that priming a self-distanced (vs self-immersed) perspective predicted decreased activity in regions linked to self-referential processing (medial prefrontal cortex; MPFC) when providing negative evaluations. This decreased MPFC activity during negative evaluations, in turn, predicted verbal feedback that was perceived to be more positive, warm and helpful. Results suggest that self-distancing can improve interpersonal perceptions and behavior by decreasing self-referential processing during the provision of criticism. © The Author (2016).

Physical activity intervention effects on perceived stress in working mothers: the role of self-efficacy.

PubMed

Mailey, Emily L; McAuley, Edward

2014-01-01

Working mothers often report elevated stress, and efforts to improve their coping resources are needed to buffer the detrimental effects of stress on health. This study examined the impact of changes in physical activity, self-efficacy, and self-regulation across the course of a brief intervention on subsequent levels of stress in working mothers. Participants (N = 141) were randomly assigned to an intervention or control condition (2:1 ratio). The intervention was conducted in Illinois between March 2011 and January 2012 and consisted of two group-mediated workshop sessions with content based on social cognitive theory. Participants completed measures of physical activity, self-efficacy, self-regulation, and perceived stress at baseline, immediately postintervention, and 6-month follow-up. Stress levels declined across the 6-month period in both groups. Changes in stress were negatively associated with changes in self-efficacy and self-regulation among intervention participants only. Regression analyses revealed the intervention elicited short-term increases in physical activity, self-efficacy, and self-regulation, but only changes in self-efficacy predicted perceived stress at 6-month follow-up. These results suggest that enhancing self-efficacy is likely to improve working mothers' perceived capabilities to cope with stressors in their lives. Future interventions should continue to focus on increasing self-efficacy to promote improvements in physical activity and psychological well-being in this population.

Executive functioning independently predicts self-rated health and improvement in self-rated health over time among community-dwelling older adults.

Self-rated health, as distinct from objective measures of health, is a clinically informative metric among older adults. The purpose of our study was to examine the cognitive and psychosocial factors associated with self-rated health. 624 participants over the age of 60 were assessed at baseline, and of these, 510 were contacted for a follow-up two years later. Measures of executive function and self-rated health were assessed at baseline, and self-rated health was assessed at follow-up. We employed multiple linear regression analyses to investigate the relationship between executive functioning and self-rated health, while controlling for demographic, psychosocial and biological variables. Controlling for other relevant variables, executive functioning independently and solely predicted self-rated health, both at a cross-sectional level, and also over time. Loneliness was also found to cross-sectionally predict self-rated health, although this relationship was not present at a longitudinal level. Older adults' self-rated health may be related to their executive functioning and to their loneliness. Self-rated health appeared to improve over time, and the extent of this improvement was also related to executive functioning at baseline. Self-rated health may be a judgement made of one's functioning, especially executive functioning, which changes with age and therefore may be particularly salient in the reflections of older adults.

A model to increase rehabilitation adherence to home exercise programmes in patients with varying levels of self-efficacy.

PubMed

Picha, Kelsey J; Howell, Dana M

2018-03-01

Patient adherence to rehabilitation programmes is frequently low - particularly adherence to home exercise programmes. Home exercise programmes have been identified as complementary to clinic-based physical therapy in an orthopaedic setting. Barriers to patient adherence have previously been identified within the literature. Low self-efficacy is a barrier to adherence that clinicians have the ability to have an impact on and improve. The theory of self-efficacy is defined as a person's confidence in their ability to perform a task. This theory examines the ability of a person to change through exerting control over inner processes of goal setting, self-monitoring, feedback, problem solving and self-evaluation. If clinicians are able to identify patients with low self-efficacy prior to the prescription of a home exercise programme, adjustments to individualized care can be implemented. Individualized care based on improving self-efficacy for home exercise programmes may improve patient adherence to these programmes. The purpose of this article was to use the theory of self-efficacy to direct clinicians in providing individualized programmes to patients with varying levels of self-efficacy.

Does Self-Control Training Improve Self-Control? A Meta-Analysis.

Friese, Malte; Frankenbach, Julius; Job, Veronika; Loschelder, David D

2017-11-01

Self-control is positively associated with a host of beneficial outcomes. Therefore, psychological interventions that reliably improve self-control are of great societal value. A prominent idea suggests that training self-control by repeatedly overriding dominant responses should lead to broad improvements in self-control over time. Here, we conducted a random-effects meta-analysis based on robust variance estimation of the published and unpublished literature on self-control training effects. Results based on 33 studies and 158 effect sizes revealed a small-to-medium effect of g = 0.30, confidence interval (CI 95 ) [0.17, 0.42]. Moderator analyses found that training effects tended to be larger for (a) self-control stamina rather than strength, (b) studies with inactive compared to active control groups, (c) males than females, and (d) when proponents of the strength model of self-control were (co)authors of a study. Bias-correction techniques suggested the presence of small-study effects and/or publication bias and arrived at smaller effect size estimates (range: g corrected = .13 to .24). The mechanisms underlying the effect are poorly understood. There is not enough evidence to conclude that the repeated control of dominant responses is the critical element driving training effects.

The relationship of sex composition of class and instructor's sex to Physical Self-efficacy has yielded conflicting results in several studies. This study examined the relationship of sex composition of class and instructor's sex to scores on Physical Self-efficacy, Perceived Physical Ability, and Physical Self-presentation Confidence of 80 male students enrolled in one of four sections of a strength training class. Analysis indicated no significant difference on Physical Self-efficacy between male students who were enrolled in all male classes or in coeducational classes; improvements in scores on Physical Self-efficacy were not specific to the sex composition of the class or sex of the instructor and no significant difference on Perceived Physical Ability and Physical Self-presentation Confidence between male students who joined an all male class or a coeducational class. Perceived Physical Ability improved from the pretest to the posttest in all classes; and no improvement in scores for Physical Self-presentation Confidence was found in all classes. In conclusion, the analysis showed sex composition of the class and sex of the instructor were not significantly related to scores for self-efficacy.

Partido, B B; Wright, B M

2018-03-02

Dental professionals are at high risk of musculoskeletal disorders (MSDs) due to static working positions for extended periods of time. Musculoskeletal pain has been identified as early as during their entry-level dental education. The purpose of this study was to determine whether feedback involving photography and self-assessment would improve ergonomic scores and the accuracy of ergonomic self-assessments amongst dental students. The study involved a randomised control design of 135 dental students. At weeks 1 and 4, participants were photographed, and at weeks 1 through 4, participants completed ergonomic self-evaluations, using a Modified-Dental Operator Posture Assessment Instrument (M-DOPAI). During weeks 2 and 3, participants in the training group were photographed and used those photographs to complete ergonomic self-assessments. All participants' pre-training and post-training photographs were evaluated for ergonomic scores by two raters. A mixed-design ANOVA of ergonomic scores revealed that ergonomic scores improved for all students who received the ergonomics training (F(1,254)=17.41, P < .001). In addition, a mixed-design ANOVA of kappa coefficient values between student and rater scores revealed that the accuracy of self-assessments improved for all students who received the ergonomics training (F(1,127)=6.33, P < .05). The use of photographs and self-assessment provides dental and dental hygiene educators with a pragmatic method to improve self-assessment skills, increase student awareness of any postural deviations from ideal and improve musculoskeletal health. © 2018 John Wiley & Sons A/S.

To determine whether an interactive self-management Website for people with chronic back pain would significantly improve emotional management, coping, self-efficacy to manage pain, pain levels, and physical functioning compared with standard text-based materials. The study utilized a pretest-posttest randomized controlled design comparing Website (painACTION-Back Pain) and control (text-based material) conditions at baseline and at 1-, 3, and 6-month follow-ups. Two hundred and nine people with chronic back pain were recruited through dissemination of study information online and at a pain treatment clinic. The 6-month follow-up rates for the Website and control groups were 73% and 84%, respectively. Measures were based on the recommendations of the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials and included measures of pain intensity, physical functioning, emotional functioning, coping, self-efficacy, fear-avoidance, perceived improvement with treatment, self-efficacy, and catastrophizing. Compared with controls, painACTION-Back Pain participants reported significantly: 1) lower stress; 2) increased coping self-statements; and 3) greater use of social support. Comparisons between groups suggested clinically significant differences in current pain intensity, depression, anxiety, stress, and global ratings of improvement. Among participants recruited online, those using the Website reported significantly: 1) lower "worst" pain; 2) lower "average" pain; and 3) increased coping self-statements, compared with controls. Participants recruited through the pain clinic evidenced no such differences. An online self-management program for people with chronic back pain can lead to improvements in stress, coping, and social support, and produce clinically significant differences in pain, depression, anxiety, and global rates of improvement.

Tell me the gossip: the self-evaluative function of receiving gossip about others.

PubMed

Martinescu, Elena; Janssen, Onne; Nijstad, Bernard A

2014-12-01

We investigate the self-evaluative function of competence-related gossip for individuals who receive it. Using the Self-Concept Enhancing Tactician (SCENT) model, we propose that individuals use evaluative information about others (i.e., gossip) to improve, promote, and protect themselves. Results of a critical incident study and an experimental study showed that positive gossip had higher self-improvement value than negative gossip, whereas negative gossip had higher self-promotion value and raised higher self-protection concerns than positive gossip. Self-promotion mediated the relationship between gossip valence and pride, while self-protection mediated the relationship between gossip valence and fear, although the latter mediated relationship emerged for receivers with mastery goals rather than performance goals. These results suggest that gossip serves self-evaluative functions for gossip receivers and triggers self-conscious emotions. © 2014 by the Society for Personality and Social Psychology, Inc.

Self-instruction: An analysis of the differential effects of instruction and reinforcement

Roberts, Richard N.; Nelson, Rosemery O.; Olson, Terry W.

1987-01-01

This study investigated the impact of training 9 first- and second-grade children to use a full self-instructional regimen, and then differentially reinforced the use of self-instruction only, accuracy only, or both self-instruction and accuracy. Three comparison children received no training in self-instruction and were reinforced for accuracy only. Children improved dramatically in academic accuracy subsequent to self-instructional training, independent of the use of self-instruction and of the specific behavior consequated. Children who were reinforced for using self-instruction did use self-instruction, and those who were not, did not. Comparison group children showed little improvement until training in problem-solving strategies was given after 9 days of reinforcement for accuracy. Self-instructional training is discussed as one type of event that increases the likelihood of accurate performance. Its effectiveness may be explained in terms of a teaching strategy rather than in terms of modifying cognitive processes. PMID:16795700

The aim of this study was to evaluate motivations, self-esteem, and oral health for undergoing orthognathic patients by gender in China before orthognathic surgery. Using a prospective and control study design, 429 subjects in China were collected from December 2010 to May 2011. The patient group consisted of 210 consecutive healthy patients, and 219 young individuals comprised the control group. All the subjects filled out a questionnaire and were assessed by Self-esteem Scale and Oral Health Impact Profile validated for Chinese patients before surgery. To measure the discrepancy, the Student t test was computed. P <0.05 was considered significant. In China, major motivations for orthognathic surgery are to improve facial appearance (83.33%), occlusion (50%), and self-confidence (48.1%). Females expect to improve facial appearance (83.87%), self-confidence (43.55%), and occlusion (41.94%). Males are for the improvement of facial appearance (82.56%), occlusion (63.95%), and self-confidence (54.65%). Self-esteem in the patient group is obviously lower (P < 0.01). There is a significant difference of self-esteem in female groups (P < 0.01), but none in male groups. Statistically significant differences were observed on oral health between both sexes. (1) Special attention should be paid on patients' ethnic, economic, cultural, and social aspects. In Chinese orthognathic patients, improving facial appearance is the primary motivation. Self-confidence has been more frequently mentioned, while headache far less than other countries. (2) Female patients have less self-esteem than females in the control group. (3) Patients' oral health are worse than those in the control group.

The purpose of this study was to conduct a diabetes education program delivered by community health workers (CHWs) in community settings and to evaluate its effectiveness in improving glycemic control and self-management skills in Hispanics/Latinos with type 2 diabetes. Trained CHWs recruited Hispanic/Latino community residents with self-reported type 2 diabetes, implemented intervention in nonclinical locations, and collected data on diabetes knowledge, self-care behaviors, self-efficacy, depression, A1C, weight, and blood pressure. Classes applied participatory techniques and were delivered in 2-hour group sessions over 10 weeks. Two focus groups collected qualitative postintervention data. Seventy participants enrolled, and 47 completed pretest and posttest data. Improvements were significant for A1C (P = .001) and systolic blood pressure (P = .006). Other positive outcomes were diabetes knowledge, physical activity, spacing carbohydrates, following a healthy eating plan, and eating fruits and vegetables. Improved behaviors also included foot care, glucose self-monitoring, and medication adherence. Depressive symptoms showed a positive trend in intent-to-treat analysis (P = .07), but self-efficacy did not change significantly (P = .142). Qualitative information reported an increase in participants' perceived competence in self-care and a positive influence of CHWs in participants' compliance with the program. A diabetes self-management education program for Hispanics/Latinos led by CHWs can be implemented in community settings and may effectively improve behavioral skills and glycemic control.

Psychiatric treatment of suicidal youths is often difficult and non-compliance in treatment is a significant problem. This prospective study compared characteristics and changes in cognitive functioning, self image and psychosocial functioning among 13 to 18 year-old adolescent psychiatric inpatients with suicide attempts (n = 16) and with no suicidality (n = 39) The two-group pre-post test prospective study design included assessments by a psychiatrist, a psychologist and medical staff members as well as self-rated measures. DSM-III-R diagnoses were assigned using the SCID and thereafter transformed to DSM-IV diagnoses. Staff members assessed psychosocial functioning using the Global Assessment Scale (GAS). Cognitive performance was assessed using the Wechsler Adult Intelligence Scale, while the Offer Self-Image Questionnaire (OSIQ) was used to assess the subjects' self-image. ANCOVA with repeated measures was used to test changes from entry to discharge among the suicide attempters and non suicidal patients. Logistic regression modeling was used to assess variables associated with an improvement of 10 points or more in the GAS score. Among suicide attempter patients, psychosocial functioning, cognitive performance and both the psychological self and body-image improved during treatment and their treatment compliance and outcome were as good as that of the non-suicidal patients. Suicidal ideation and hopelessness declined, and psychosocial functioning improved. Changes in verbal cognitive performance were more pronounced among the suicide attempters. Having an improved body-image associated with a higher probability of improvement in psychosocial functioning while higher GAS score at entry was associated with lower probability of functional improvement in both patient groups. These findings illustrate that a multimodal treatment program seems to improve psychosocial functioning and self-image among severely disordered suicidal adolescent inpatients. There were no changes in familial relationships, possibly indicating a need for more intensive family interventions when treating suicidal youths. Multimodal inpatient treatment including an individual therapeutic relationship seems recommendable for severely impaired psychiatric inpatients tailored to the suicidal adolescent's needs.

Reciprocal effects of exercise and nutrition treatment-induced weight loss with improved body image and physical self-concept.

PubMed

Annesi, James J; Porter, Kandice J

2015-01-01

Improvements in self-image and mood are often reported as outcomes of obesity interventions. However, they may also concurrently influence weight loss, suggesting a reciprocal effect. Although previously reported for overweight women, such relationships were untested in morbidly obese women whose psychosocial responses to treatment may be different, and health-risks greater. Women (N = 161, Meanage = 42 years) with morbid obesity (MeanBMI = 45.1 kg/m(2)) participated in a 6-month, behaviorally based physical activity and nutrition treatment. Significant within-group improvements in weight-loss behaviors (physical activity and eating), weight, body satisfaction, physical self-concept, and depression were found. After controlling for age, mediation analyses indicated that, as a result of the treatment, weight loss was both an outcome and mediator of improvements in body-areas satisfaction and physical self-concept (reciprocal effects), but not depression. Results replicated findings from women with lower degrees of overweight, and suggested that weight-loss treatments emphasize changes in self-perception.

Does self-monitoring of blood glucose levels improve dietary compliance for obese patients with type II diabetes?

PubMed

Wing, R R; Epstein, L H; Nowalk, M P; Scott, N; Koeske, R; Hagg, S

1986-11-01

Self-monitoring of blood glucose levels is currently being recommended for obese patients with type II diabetes to improve weight loss and glycemic control. To determine whether self-monitoring of blood glucose levels improves dietary compliance in these patients, 50 obese patients with type II diabetes were randomly assigned either to a standard behavioral weight control program or to a weight control program that included self-monitoring of blood glucose levels and focused on the weight-blood glucose relationship. Both groups lost significant amounts of weight and maintained their losses for at least one year; reductions in medication could be made for 70 percent of patients. These data suggest that the behavioral weight control used in this study may be of benefit to patients with type II diabetes. However, there was no evidence that the addition of self-monitoring of blood glucose levels to the treatment program improved the outcome in terms of weight loss, reduction in medication, dietary compliance, or mood state.

To analyse the efficacy of improving disease management after implementing a self-management programme for people with type 2 diabetes administered by healthcare workers who have received special training. The needs for diabetic care include increased training for healthcare providers to enhance their confidence and skills in managing patients, both physically and mentally. Quasi-experimental design. This study recruited participants from outpatient clinics in 10 hospitals in Taiwan. In 2010, purposive sampling was used to recruit 228 participants from two medical centres, five regional hospitals and three district hospitals. Participants were enrolled in a 'diabetes self-management programme' (watching patient videos, reading a diabetes self-care handbook, participating in four consultation courses of diabetes self-efficacy improvement, telephone follow-up and positive reinforcement). Efficacy analysis of post-test diabetes outcome variables of the experimental group was carried out. Sex, age and pretest score were used as the control variables for ancova test. Patients in the experimental group had significant improvement in body mass index (p < 0·01), waistline circumference (p < 0·001), haemoglobin A1C levels (p < 0·001), degrees of anxiety and depression (p < 0·001), self-efficacy (p < 0·001) and levels of self-care (p < 0·001). Self-efficacy of people with diabetes can be effectively improved by planned implementation of a 'diabetes self-management programme' by trained healthcare workers. The diabetes care professionals are provided the self-management programme to strengthen the awareness and importance of self-management in diabetes care. © 2013 John Wiley & Sons Ltd.

The purpose of this study was to investigate the effects of a self-esteem improvement program on self-esteem and peer attachment in elementary school children with observed problematic behaviors. This study is a quasi-experimental study with a nonequivalent control group pretest-post-test design. A total of 47 fourth grade elementary school students participated in this study. The program was provided for 45 minutes once a week; a total of 12 sessions were completed with a group in the classroom for the experimental group. Child Problem-Behavior Screening Questionnaire was used to measure problematic behavior. Self-esteem was measured using the Rosenberg's Self-esteem Questionnaire, and peer attachment was measured using the Inventory of Parent and Attachment. Measuring was performed right after the program was done (post 1) and 1 month after the program was finished (post 2). To compare the differences in self-esteem and peer attachment between groups, repeated measures analysis of variance was used. Most participants in the experimental group were 10 years old (62.5%, range 10-11), male (52.0%) and with middle grade point average (64.0%). The self-esteem scores in the experimental group were significantly higher than those of the control group (F = 26.64, p < .001). The peer attachment scores in the experimental group were significantly higher than those of the control group (F = 6.48, p = .014). The self-esteem improvement program in this study improved the self-esteem and peer attachment in elementary school children. The self-esteem program helped acknowledge the peer's name and increased their connections. The program needs to be considered as a formal and consistent program. Copyright © 2015.

To assess the feasibility, acceptability, and preliminary effectiveness of a peer-delivered and technology supported integrated medical and psychiatric self-management intervention for older adults with serious mental illness. Ten older adults with serious mental illness (i.e., schizophrenia, schizoaffective disorder, bipolar disorder, or major depressive disorder) and medical comorbidity (i.e., cardiovascular disease, obesity, diabetes, chronic obstructive pulmonary disease, hypertension, and/or high cholesterol) aged 60 years and older received the PeerTECH intervention in their homes. Three certified peer specialists were trained to deliver PeerTECH. Data were collected at baseline, one-month, and three-month. The pilot study demonstrated that a three-month, peer-delivered and technology-supported integrated medical and psychiatric self-management intervention ("PeerTECH") was experienced by peer specialists and participants as feasible and acceptable. PeerTECH was associated with statistically significant improvements in psychiatric self-management. In addition, pre/post, non-statistically significant improvements were observed in self-efficacy for managing chronic health conditions, hope, quality of life, medical self-management skills, and empowerment. This pre/post pilot study demonstrated it is possible to train peers to use technology to deliver an integrated psychiatric and medical self-management intervention in a home-based setting to older adults with serious mental illness with fidelity. These findings provide preliminary evidence that a peer-delivered and technology-supported intervention designed to improve medical and psychiatric self-management is feasible, acceptable, and is potentially associated with improvements in psychiatric self-management, self-efficacy for managing chronic health conditions, hope, quality of life, medical self-management skills, and empowerment with older adults with serious mental illness and chronic health conditions.

The stigma of nasal deformity due to a congenital cleft lip-palate has an undeniable influence on the affected patient's life. It is therefore of interest to investigate if efforts to reduce esthetic and functional impairments by rhinoplasty (single or multiple) can result in an increased satisfaction with appearance and a self-perception similar to the noncleft population. Retrospective scoring before and after rhinoplasty using the validated Derriford Appearance Scale (DAS-59) and subsequent statistical evaluation and comparison to datasets available in the literature for further classification was used. Of the 61 patients who underwent at least one rhinoplasty, 26 responded to all questions. The mean age of responders was approximately 30 years of age and the male:female ratio was 1:1.2. The scale showed a significant overall improvement after surgery. The full scale and all subscale scores of the DAS-59 were significantly reduced after surgery demonstrating an improvement in the respective categories. Most importantly, if postoperative results were compared with a population concerned and unconcerned about appearance, no difference "facial self-consciousness" of appearance was apparent. Also postoperative subscores for "general self-consciousness" (GSC) and "social self-consciousness" of appearance (SSC) showed no difference from those obtained from the population concerned about appearance. The postoperative subscore for "sexual and bodily self-consciousness" of appearance (SBSC) indicated improvement beyond the level found in the concerned control population. Due to only a low improvement in the difference compared with the subscore representing a "negative self-concept," a statistically significant difference to the concerned population remained, possibly indicating that therapy beyond surgery is needed for improvement. After rhinoplasty, the investigated group of cleft lip-palate patients with nasal deformities showed an improvement in their self-conceived appearance as measured by the DAS-59. Their assessment of self-appearance was comparable to that of a group of noncleft persons with concern about their appearance. Taken together, rhinoplasties, primary and revision, add to the psychosocial well-being and an improved self-perception enhancing quality of life and enabling a more normal life. Further research is needed to clarify how the low reduction found in the "negative self-concept" may be addressed successfully. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Studies have shown that postdischarge care for self-harm patients is effective in reducing repeated suicidal behaviors. Little is known about whether volunteer support can help reduce self-harm repetition and improve psychosocial well-being. This study investigated the efficacy of volunteer support in preventing repetition of self-harm. This study used a quasi-experimental design by assigning self-harm patients admitted to the emergency departments to an intervention group with volunteer support and treatment as usual (TAU) for 9 months and to a control group of TAU. Outcome measures include repetition of self-harm, suicidal ideation, hopelessness, and level of depressive and anxiety symptoms. A total of 74 cases were recruited (38 participants; 36 controls). There were no significant differences in age, gender, and clinical condition between the two groups at the baseline. The intervention group showed significant improvements in hopelessness and depressive symptoms. However, the number of cases of suicide ideation and of repetition of self-harm episodes was similar for both groups at the postintervention period. Postdischarge care provided by volunteers showed significant improvement in hopelessness and depression. Volunteers have been commonly involved in suicide prevention services. Further research using rigorous methods is recommended for improving service quality in the long term.

Previous evidence suggests self-management programs for people with chronic pain improve knowledge and self-efficacy, but result in small to negligible changes in function. The purpose of this multiple case studies design was to describe the unique responses of six participants to a new self-management program aimed at improving function, to detail each component of the program, and to explore potential explanations for the varied trajectories of each of the participants. Six participants who had been experiencing chronic pain for at least 5 years were included. All participants were enrolled 6 weeks of ChrOnic pain self-ManageMent support with pain science EducatioN and exercise (COMMENCE). Participants completed an assessment at baseline, 7 weeks (1-week follow-up), and 18 weeks (12-week follow-up). Each participant had a unique initial presentation and goals. Assessments included: function as measured by the Short Musculoskeletal Function Assessment - Dysfunction Index, how much participants are bothered by functional difficulties, pain intensity, fatigue, pain interference, cognitive and psychological factors associated with pain and disability, pain neurophysiology, self-efficacy, satisfaction, and perceived change. The self-management program was 6-weeks in length, consisting of one individual visit and one group visit per week. The program incorporated three novel elements not commonly included in self-management programs: pain neurophysiology education, individualized exercises determined by the participants' goals, and additional cognitive behavioural approaches. Participants were all satisfied with self-management support received. Change in function was variable ranging from 59% improvement to 17% decline. Two potential explanations for variances in response, attendance and social context, are discussed. Several challenges were identified by participants as barriers to attendance. A primary care self-management intervention including pain education and individualized exercise has potential to improve function for some people with chronic pain, although strategies to improve adherence and reduce barriers to participation may be needed to optimize the impact.

The purpose of this study was to investigate sex differences in psychological effects of exercise on university students. University students (73 female and 65 male) were randomly assigned to experimental and control groups by equating sex in each group. The experimental group participated in step dance sessions of 50 min per day, 3 days per week for 10 weeks with 60-80% of their heart rate reserves. Throughout the 10-week period, the lecture control group was told not to participate in any organized or structured exercise and participated in a lecture that was about the physiological and psychological benefits of exercise. Self-concept, belief in external control, and trait anxiety of the groups were measured before and after the exercise program. A significant improvement in the psychological variables after the exercise program and more improvement for female exercise participants were expected. Analysis revealed no significant initial differences in self-concept, belief in external control, and trait anxiety between the two groups or between males and females, other than family and moral/ethical self. Repeated measures analysis of variance revealed that exercise led to less belief in external control and significant improvement in physical self and identity dimensions of self-concept for the experimental group compared to the control group. However, there was no significant difference in trait anxiety between the two groups after exercise (p>.05). Analysis also revealed that changes in belief in external control, trait anxiety, and self-concept did not differ with regard to sex. Males and females showed no difference in their improvement on trait anxiety, belief in external control, and most dimensions of self-concept during the 10 weeks. Only changes in personal and physical self throughout 10-week period were different for males and females. Exerciser males improved their personal self and physical self scores more than female exercisers and male and female nonexercisers throughout the 10-week period (p<.05).

There is evidence that the stigma surrounding mental illness may be greater in Japan than elsewhere. However, few Japanese studies have focused on self-stigma (the internalization of social stigma), and few interventions to reduce self-stigma exist. To remedy this deficiency, we evaluated the efficacy of group cognitive-behavioral therapy (CBT) in reducing self-stigma and examined the relationship between cognitive restructuring and self-stigma. We administered a 10-session group CBT program to 46 Japanese outpatients with anxiety and depressive symptoms (36 men, 10 women; mean age=38.57 years, SD=8.33; 20 diagnosed with mood disorders; 24 with neurotic, stress-related, or somatoform disorders; and 2 with other disorders). A pretest-posttest design was used to examine the relationship between cognitive restructuring and self-stigma. Outcomes were measured using the Japanese versions of the Devaluation-Discrimination Scale, Dysfunctional Attitude Scale, Beck Depression Inventory-II, State-Trait Anxiety Inventory State-Form, and Rosenberg's Self Esteem Scale. Participants exhibited significant improvements in depression, anxiety, and maladjusted cognitive bias and reductions in self-stigma. Cognitive bias was significantly correlated with self-stigma. Group CBT is effective in improving both emotional symptoms and self-stigma in outpatients with anxiety and depressive symptoms. Reduction in self-stigma plays a mediating role in alleviating emotional symptoms and improving cognition. Copyright © 2014 Elsevier B.V. All rights reserved.

We examined the impact of training-induced improvements in self-regulation, operationalized in terms of response inhibition, on longitudinal changes in self-reported adaptive socioemotional functioning. Data were collected from participants undergoing 3 months of intensive meditation training in an isolated retreat setting (Retreat 1) and a wait-list control group that later underwent identical training (Retreat 2). A 32-min response inhibition task (RIT) was designed to assess sustained self-regulatory control. Adaptive functioning (AF) was operationalized as a single latent factor underlying self-report measures of anxious and avoidant attachment, mindfulness, ego resilience, empathy, the five major personality traits (extroversion, agreeableness, conscientiousness, neuroticism, and openness to experience), difficulties in emotion regulation, depression, anxiety, and psychological well-being. Participants in Retreat 1 improved in RIT performance and AF over time whereas the controls did not. The control participants later also improved on both dimensions during their own retreat (Retreat 2). These improved levels of RIT performance and AF were sustained in follow-up assessments conducted approximately 5 months after the training. Longitudinal dynamic models with combined data from both retreats showed that improvement in RIT performance during training influenced the change in AF over time, which is consistent with a key claim in the Buddhist literature that enhanced capacity for self-regulation is an important precursor of changes in emotional well-being.

We evaluated the associations of risk perception, self-efficacy, and trust with two health promotion behaviors (food habits and exercise) and depressive mood. Diabetic patients aged between 40 and 64 ( n = 1195) were included in the analyses. Risk perception worsened behavioral changes in terms of food habits and depression, whereas self-efficacy and trust improved food habits, exercise, and depression; trust improved exercise and depression. In conclusion, self-efficacy and trust appear to be more beneficial than risk perception for positive behavioral changes and for improving depression in diabetic patients. However, their influence on behavioral changes may be different according to the types of behaviors.

Twenty-five final-year undergraduate students of primary education who were attending a course on mathematics education participated in a research project during the 2009 spring semester. A repeated measures experimental design was used. Quantitative data on students' computer attitudes, self-efficacy in ICT, attitudes toward educational software, and self-efficacy in maths were collected. Data analysis showed a statistically non-significant improvement on participants' computer attitudes and self-efficacy in ICT and ES, but a significant improvement of self-efficacy in mathematics.

Supporting self-care in general practice

PubMed Central

Greaves, Colin J; Campbell, John L

2007-01-01

There is both a clear need and a political will to improve self-care in long-term conditions: demand for self-care support interventions is rising. This article discusses current approaches to supporting self-care in primary care, evidence in favour of self-care support, and issues for GPs to consider in planning self-care support systems. In planning care pathways, important choices need to be made about whether to use individual or group-based approaches and what intensity of intervention is appropriate to match patient needs. Investment may also be needed in both health professional competences and practice systems to optimise their ability to support patient self-care. Self-care support is a key approach for the future of UK health care. Practices that are well trained and well organised to support self-care will respond better to the complex challenges of achieving improvements in the outcomes of long-term conditions. PMID:17925140

This study investigated the effects of group music therapy on improving anxiety, depression, and self-esteem in Chinese prisoners. Two-hundred male prisoners were randomly assigned to music therapy (n = 100) or standard care (n = 100). The music therapy had 20 sessions of group therapy compared with standard care. Anxiety (State and Trait Anxiety Inventory [STAI]), depression (Beck Depression Inventory [BDI]), and self-esteem (Texas Social Behavior Inventory [TSBI], Rosenberg Self-Esteem Inventory [RSI]) were measured by standardized scales at baseline, mid-program, and post-program. Data were analyzed based on the intention to treat principle. Compared with standard care, anxiety and depression in the music therapy condition decreased significantly at mid-test and post-test; self-esteem improved significantly at mid-test (TSBI) and at post-test (TSBI, RSI). Improvements were greater in younger participants (STAI-Trait, RSI) and/or in those with a lower level of education (STAI-State, STAI-Trait). Group music therapy seems to be effective in improving anxiety, depression, and self-esteem and was shown to be most beneficial for prisoners of younger age or with lower education level. © The Author(s) 2015.

Recently, a Dutch educational broadcasting company developed a 6 week self-help course for insomnia, which consists of a book and television programmes. In this study we examined its effects. 247 subjects with sleep problems were recruited through the media and randomized to the self-help treatment (n=126) or a waiting list control group (n=121). The intervention group received the book, and for 6 consecutive weeks a DVD or videotape. Subjects were assessed before and after the course. Both groups improved significantly with respect to sleep but there were no significant differences in improvements between the groups. However, the intervention group improved significantly more on secondary outcomes: the subjective evaluation of sleep quality (d=0.65), dysfunctional beliefs and attitudes about sleep (d=0.62), depressive symptoms (d=0.35), and quality of life (d=0.34). Cognitive-behavioral self-help treatment does not necessarily lead to sleep improvements but it does improve coping with insomnia. About 2% of the Dutch adult population has watched the regular broadcastings of the course after the trial ended. This huge number of viewers underlines that there is a need for this type of low cost self-help treatment.

Self-management interventions have become increasingly popular in the management of long-term health conditions; however, little is known about their impact on psychological well-being in people with Multiple Sclerosis (MS). To examine the effectiveness of self-management interventions on improving depression, anxiety and health related quality of life in people with MS. A structured literature search was conducted for the years 2000 to 2016. The review process followed the PRISMA guidelines, and is registered with PROSPERO (no. CRD42016033925). The review identified 10 RCT trials that fulfilled selection criteria and quality appraisal. Self-management interventions improved health-related quality of life in 6 out of 7 studies, with some evidence of improvement in depression and anxiety symptoms. Although the results are promising more robust evaluation is required in order to determine the effectiveness of self-management interventions on depression, anxiety and quality of life in people with MS. Evaluation of the data was impeded by a number of methodological issues including incomplete content and delivery information for the intervention and the exclusion of participants representing the disease spectrum. Recommendations are made for service development and research quality improvement.

This study aimed to investigate the effect of self-transcendence on the physical health of multiple sclerosis (MS) patients attending peer support groups. This study was a quasi-experimental before-and-after design including 33 MS patients in three groups: 10 men in the men-only group, 11 women in the women-only group, and 12 men and women in the mixed group. Participants were required to attend eight weekly sessions of 2 h each. Instruments included the physical health section of the Multiple Sclerosis Quality of Life Inventory and Reed's Self-Transcendence Scale. Peer support group attendance was found to have a significant positive effect on the physical health and self-transcendence of MS patients when comparing average scores before and after attendance. Regression analysis showed that improvement in self-transcendence predicted improvement in physical health. Results show the positive effects of peer support groups on self-transcendence and physical health in MS patients, and suggest that improvement in well-being can be gained by promoting self-transcendence and physical health. © 2015 Wiley Publishing Asia Pty Ltd.

To investigate the effectiveness of a program that utilizes community involvement to improve the self-management strategies among people living with hypertension. Forty-four subjects, aged 35 to 59-year-old, with hypertension in Nakhon Pathom Province, Thailand, were randomly allocated to either an experimental group (n = 22) or a control group (n = 20). The experimental group attended a program to improve self-management methods based on social cognitive theory (SCT). The program lasted 12 weeks, consisted of 1 1/2 hours meeting once a week, including group meetings and home visit monitoring. Mann-Whitney U test and Friedman test were employed to analyze the program's effectiveness. After the program, the mean rank of the perceived self-efficacy for the self-management strategies was statistically different between the two groups (p = 0.023). In the experimental group, after the twelve week, the mean rank of perceived self-efficacy and outcome expectancy increased and diastolic blood pressure decreased after the eight week. The program applied social cognitive theory (SCT) to promote self-management techniques, increased the health promoting behavior among hypertensive people.

Test results for rotordynamic coefficients of anti-swirl self-injection seals

Test results are presented for rotordynamic coefficients and leakage for three annular seals which use anti-swirl self-injection concept to yield significant improvement in whirl frequency ratios as compared to smooth and damper seals. A new anti-swirl self-inection mechanism is achieved by deliberately machining self-injection holes inside the seal stator mechanism which is used to achieve effective reduction of the tangential flow which is considered as a prime cause of rotor instability in high performance turbomachinery. Test results show that the self-injection mechanism significantly improves whirl frequency ratios; however, the leakage performance degrades due to the introduction of the self-injection mechanism. Through a series of the test program, an optimum anti-swirl self-injection seal which uses a labyrinth stator surface with anti-axial flow injections is selected to obtain a significant improvement in the whirl frequency ratio as compared to a damper seal, while showing moderate leakage performance. Best whirl frequency ratio is achieved by an anti-swirl self-injection seal of 12 holes anti-swirl and 6 degree anti-leakage injection with a labyrinth surface configuration. When compared to a damper seal, the optimum configuration outperforms the whirl frequency ratio by a factor of 2.

The impact of Next Generation Science Standards (NGSS) professional development on the self-efficacy of science teachers

NASA Astrophysics Data System (ADS)

Akella, Somi Devi M.

In 2012, the National Research Council introduced the Next Generation Science Standards (NGSS), which were created to improve the K-12 education in the U.S. and stress the importance of providing professional development (PD) to acquire the knowledge, skills, and self-efficacy to design lessons to meet high standards of teaching and learning. Bandura's (1977) theory of self-efficacy posits that people are motivated to perform an action if they are confident that they can perform the action successfully. The purpose of this survey research was to investigate the impact of professional development on the self-efficacy of science teachers with regard to the NGSS practice of Analyzing and Interpreting Data as well as to probe teachers' perceptions of barriers to their self-efficacy in applying this practice. The study found that focused and targeted PD helped improve participants' self-efficacy in incorporating the NGSS practices and addressed several barriers to teacher self-efficacy. In response to findings, Akella's Science Teaching Efficacy Professional Development (ASTEPD) model is proposed as a tool to guide PD practice and, thus, helps improve teacher self-efficacy.

Self-care is defined as a naturalistic decision-making process addressing both the prevention and management of chronic illness, with core elements of self-care maintenance, self-care monitoring, and self-care management. In this scientific statement, we describe the importance of self-care in the American Heart Association mission and vision of building healthier lives, free of cardiovascular diseases and stroke. The evidence supporting specific self-care behaviors such as diet and exercise, barriers to self-care, and the effectiveness of self-care in improving outcomes is reviewed, as is the evidence supporting various individual, family-based, and community-based approaches to improving self-care. Although there are many nuances to the relationships between self-care and outcomes, there is strong evidence that self-care is effective in achieving the goals of the treatment plan and cannot be ignored. As such, greater emphasis should be placed on self-care in evidence-based guidelines. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

The Japanese Orthopaedic Association (JOA) scoring system is a physician-based outcome that has been used to evaluate treatment effectiveness after lumbar surgery. However, patient-centered evaluation becomes increasingly important. There is no study that has examined the relationship between the JOA scoring system and patients' self-reported improvement. The purpose of the present study was to validate the JOA scoring system for assessment of patient-reported improvement after lumbar surgery. This is a retrospective review of prospectively collected data. The patient sample included 273 mail-in responders of the 466 consecutive patients who underwent posterior lumbar interbody fusion for spondylolisthesis between 1996 and 2008 in a single hospital. The outcome measures were the JOA scoring system and patients' self-reported improvement. Two hundred seventy three patients were divided into five anchoring groups based on self-reported improvement from "Much better" to "Much worse." Outcomes (ie, recovery rate, amount of change from preoperative condition, and postoperative score) based on the JOA scoring system were compared among groups. Using the patient's self-reported improvement scale as an anchor, the association among each of the outcomes was examined. The cutoff point and the area under the curve (AUC) that differentiated "Improved" from "Neither improved nor worse" was calculated using receiver operating characteristic (ROC) curve analysis. The recovery rate and postoperative score were significantly different in 9 of 10 pairs of anchoring groups. The amount of change was significantly different in six pairs. Spearman correlation coefficient for the 5-point scale anchors of patients' self-reported improvement was 0.20 (p=.001) for the baseline score, 0.31 (p<.001) for the amount of change, 0.55 (p<.001) for the recovery rate, and 0.56 (p<.001) for the postoperative score. According to ROC analysis, the best cutoff points and AUCs were 13 points and 0.69, respectively, for the amount of change, 67% and 0.73, respectively, for recovery rate, and 23 points and 0.72, respectively, for postoperative score. The JOA scoring system is a valid method for assessment of patients' self-reported improvement. Patients' self-reported improvement is more likely to be associated with the final condition, such as postoperative score or recovery rate, rather than the change from the preoperative condition.

2014-01-01

Cognitive control of physical activity and sedentary behavior is receiving increased attention in the neuroscientific and behavioral medicine literature as a means of better understanding and improving the self-regulation of physical activity. Enhancing individuals’ cognitive control capacities may provide a means to increase physical activity and reduce sedentary behavior. First, this paper reviews emerging evidence of the antecedence of cognitive control abilities in successful self-regulation of physical activity, and in precipitating self-regulation failure that predisposes to sedentary behavior. We then highlight the brain networks that may underpin the cognitive control and self-regulation of physical activity, including the default mode network, prefrontal cortical networks and brain regions and pathways associated with reward. We then discuss research on cognitive training interventions that document improved cognitive control and that suggest promise of influencing physical activity regulation. Key cognitive training components likely to be the most effective at improving self-regulation are also highlighted. The review concludes with suggestions for future research. PMID:25324754

Assessing the extent of altruism in the valuation of community drinking water quality improvements

Improvements in publically provided goods and services, like community drinking water treatment, have values to people arising from their self-interest, but may as well have value from their altruistic concerns. The extent to which the value is altruistic versus self-interested is an important empirical issue for policy analysis because the benefits to improving drinking water quality may be larger than previously thought. We conducted an internet survey across Canada to identify both self-interested willingness-to-pay and altruistic willingness-to-pay obtained through hypothetical responses to a series of stated choice tasks and actual self-protection data against health risks from tap water. We use the information on self-protection to identify altruistic WTP. We find significant differences between self-interested and altruistic WTP: the latter can be three times greater than the former. Whether benefits of water protection are actually larger, however, depends on whether the altruism is paternalistic or nonpaternalistic.

2017-02-01

The aims of this review were to describe the self-management interventions used to improve risk factor control in stroke patients and quantitatively assess their effects on the following: 1) overall risk factor control from lifestyle behaviour (i.e. physical activity, diet and nutrition, stress management, smoking, alcohol, and medication adherence), and medical risk factors (i.e. blood pressure, cholesterol, blood glucose) and (2) individual risk factors. We systematically searched the PubMed, PsycINFO, CINAHL and Cochrane Database of Systematic Reviews databases to September 2015 to identify relevant randomized controlled trials investigating self-management to improve stroke risk factors. The self-management interventions were qualitatively described, and the data included in meta-analyses. Fourteen studies were included for review. The model estimating an effect averaged across all stroke risk factors was not significant, but became significant when four low-quality studies were removed (SMD = 0.10 [95 % CI = 0.02 to 0.17], I 2  = 0 %, p = 0.01). Subgroup analyses revealed a significant effect of self-management interventions on lifestyle behaviour risk factors (SMD = 0.15 [95 % CI = 0.04 to 0.25], I 2  = 0 %, p = 0.007) but not medical risk factors. Medication adherence was the only individual risk factor that self-management interventions significantly improved (SMD = 0.31 [95 % CI = 0.07 to 0.56], I 2  = 0 %, p = 0.01). Self-management interventions appear to be effective at improving overall risk factor control; however, more high-quality research is needed to corroborate this observation. Self-management has a greater effect on lifestyle behaviour risk factors than medical risk factors, with the largest effect at improving medication adherence.

Improving patient care for individuals with lung cancer is a priority due to the increasing burden of the disease globally. One way this can be done is by improving patient self-management capabilities through increasing their self-efficacy. This can improve positive outcomes for patients with chronic conditions and increase their ability to manage the challenges of such illnesses. Unfortunately, patients with chronic conditions often struggle to travel far from home to engage with patient education events, a common means of improving self-efficacy. The development of more accessible tools for improving patient self-efficacy is required to increase quality of life for patients with chronic conditions. To evaluate the feasibility of delivering symptom identification and management information to patients with advanced lung cancer using an online program. This article describes a pre-post test study to evaluate a Qstream online learning platform to improve patient self-efficacy for managing advanced lung cancer symptoms. Undertaking this program should increase participant knowledge about the side-effects they may experience as a result of their treatment and in turn increase help-seeking behavior and self-efficacy for the participant cohort. Quantitative data collected by the Qstream platform on the completion rates of participants will be used as a tool to evaluate the intervention. Additionally, validated scales will be used to collect data on patient self-efficacy. Qualitative data will also be collected via an exit survey and thematic content analysis of semi-structured interviews. The research is in the preliminary stages but thus far a protocol has been approved in support of the project. Additionally, advisory committee members have been identified and initial meetings have been undertaken. Development of new approaches for increasing patient understanding of their care is important to ensure high quality care continues to be delivered in the clinical setting.

The rate of type-2 diabetes mellitus (T2D) is dramatically increasing worldwide. Continuing diabetes mellitus (DM) care needs effective self-management education and support for both patients and family members. This study aimed to review and describe the impacts of diabetes mellitus self-management education (DSME) that involve family members on patient outcomes related to patient health behaviors and perceived self-efficacy on self-management such as medication adherence, blood glucose monitoring, diet and exercise changes, health outcomes including psychological well-being and self-efficacy, and physiological markers including body mass index, level of blood pressure, cholesterol level and glycemic control. Three databases, PubMed, CINAHL, and Scopus were reviewed for relevant articles. The search terms were "type 2 diabetes," "self-management," "diabetes self-management education (DSME)," "family support," "social support," and "uncontrolled glycaemia." Joanna Briggs Institute (JBI) guidelines were used to determine which studies to include in the review. Details of the family support components of DSME intervention and the impacts of these interventions had on improving the health outcomes patients with uncontrolled glycaemia patients. A total of 22 intervention studies were identified. These studies involved different DSME strategies, different components of family support provided, and different health outcomes to be measured among T2D patients. Overall, family support had a positive impact on healthy diet, increased perceived support, higher self-efficacy, improved psychological well-being and better glycemic control. This systematic review found evidence that DSME with family support improved self-management behaviors and health outcomes among uncontrolled glycaemia T2D patients. The findings suggest DSME models that include family engagement can be a useful direction for improving diabetes care.

Haemophiliacs who have had to keep a physically inactive lifestyle due to bleeding during childhood are likely to have little motivation for exercise. The purpose of this study is to clarify the effectiveness of the self-monitoring of home exercise for haemophiliacs. A randomized controlled trial was conducted with intervention over 8 weeks at four hospitals in Japan. Subjects included 32 male outpatients aged 26-64 years without an inhibitor who were randomly allocated to a self-monitoring group and a control group. Individual exercise guidance with physical activity for improvement of their knee functions was given to both groups. The self-monitoring materials included an activity monitor and a feedback system so that the self-monitoring group could send feedback via the Internet and cellular phone. The self-monitoring was performed by checking exercise adherence and physical activity levels, bleeding history and injection of a coagulation factor. Both groups showed significant improvements in exercise adherence (P < 0.001) and physical function such as the strength of knee extension (P < 0.001), range of knee extension (P < 0.001), range of ankle dorsiflexion (P < 0.01), a modified Functional Reach (P < 0.05) and 10 metre gait time (P < 0.01). In particular, improvements in exercise adherence (P < 0.05), self-efficacy (P < 0.05), and strength of knee extension (P < 0.05) were significant in the self-monitoring group compared with those in the control group. No increase in bleeding frequency and pain scale was noted. The self-monitoring of home exercise for haemophilic patients is useful for the improvement of exercise adherence, self-efficacy and knee extension strength. © 2014 John Wiley & Sons Ltd.

The rate of type-2 diabetes mellitus (T2D) is dramatically increasing worldwide. Continuing diabetes mellitus (DM) care needs effective self-management education and support for both patients and family members. This study aimed to review and describe the impacts of diabetes mellitus self-management education (DSME) that involve family members on patient outcomes related to patient health behaviors and perceived self-efficacy on self-management such as medication adherence, blood glucose monitoring, diet and exercise changes, health outcomes including psychological well-being and self-efficacy, and physiological markers including body mass index, level of blood pressure, cholesterol level and glycemic control. Three databases, PubMed, CINAHL, and Scopus were reviewed for relevant articles. The search terms were “type 2 diabetes,” “self-management,” “diabetes self-management education (DSME),” “family support,” “social support,” and “uncontrolled glycaemia.” Joanna Briggs Institute (JBI) guidelines were used to determine which studies to include in the review. Details of the family support components of DSME intervention and the impacts of these interventions had on improving the health outcomes patients with uncontrolled glycaemia patients. A total of 22 intervention studies were identified. These studies involved different DSME strategies, different components of family support provided, and different health outcomes to be measured among T2D patients. Overall, family support had a positive impact on healthy diet, increased perceived support, higher self-efficacy, improved psychological well-being and better glycemic control. This systematic review found evidence that DSME with family support improved self-management behaviors and health outcomes among uncontrolled glycaemia T2D patients. The findings suggest DSME models that include family engagement can be a useful direction for improving diabetes care. PMID:28914815

"Ethnicity moderates the outcomes of self-enhancement and self-improvement themes in expressive writing": Correction to Tsai et al. (2015).

Reports an error in "Ethnicity moderates the outcomes of self-enhancement and self-improvement themes in expressive writing" by William Tsai, Anna S. Lau, Andrea N. Niles, Jordan Coello, Matthew D. Lieberman, Ahra C. Ko, Christopher Hur and Annette L. Stanton ( Cultural Diversity and Ethnic Minority Psychology , 2015[Oct], Vol 21[4], 584-592). In this article, there were three errors in the Results section. Each are described in the erratum alongside the correct results. The interpretations of the findings remain the same. (The following abstract of the original article appeared in record 2014-32908-001.) The current study examined whether writing content related to self-enhancing (viz., downward social comparison and situational attributions) and self-improving (viz., upward social comparison and persistence) motivations were differentially related to expressive writing outcomes among 17 Asian American and 17 European American participants. Content analysis of the essays revealed no significant cultural group differences in the likelihood of engaging in self-enhancing versus self-improving reflections on negative personal experiences. However, cultural group differences were apparent in the relation between self-motivation processes and changes in anxiety and depressive symptoms at 3-month follow-up. Among European Americans, writing that reflected downward social comparison predicted positive outcomes, whereas persistence writing themes were related to poorer outcomes. For Asian Americans, writing about persistence was related to positive outcomes, whereas downward social comparison and situational attributions predicted poorer outcomes. Findings provide evidence suggesting culturally distinct mechanisms for the effects of expressive disclosure. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Learning to re-appraise the self during video feedback for social anxiety: Does depth of processing matter?

PubMed

Orr, Elizabeth M J; Moscovitch, David A

2010-08-01

Video feedback (VF) with cognitive preparation (CP) has been widely integrated into cognitive-behavioral therapy (CBT) protocols for social anxiety disorder (SAD) due to its presumed efficacy in improving negative self-perception. However, previous experimental studies have demonstrated that improvements in negative self-perception via VF+CP do not typically facilitate anxiety reduction during subsequent social interactions - a troubling finding for proponents of cognitive models of social anxiety. We examined whether VF+CP could be optimized to enhance participants' processing of corrective self-related information through the addition of a post-VF cognitive review (CR). Sixty-eight socially anxious individuals were randomly assigned to perform two public speeches in one of the following conditions: a) exposure alone (EXP); b) CP+VF; and c) CP+VF+CR. Those in the CP+VF+CR condition demonstrated marginally significant reductions in anxiety from speech 1 to speech 2 relative to those who received EXP - an improvement not shown for those in the CP+VF condition. Furthermore, only those who received CP+VF+CR demonstrated significant improvements in self-perception and performance expectations relative to EXP. Decreases in anxiety among participants who received CP+VF+CR relative to EXP were fully mediated by improvements in self-perception. Implications are discussed in the context of cognitive models of social anxiety and mechanisms of exposure-based learning. Copyright 2010 Elsevier Ltd. All rights reserved.

Hansson, Lars; Lexén, Annika; Holmén, Joacim

2017-11-01

Stigma has been proposed to be one of the most serious obstacles to successful treatment, rehabilitation and inclusion in society of people with severe mental illness. An aspect of stigma which has been increasingly discussed is self-stigma, which refers to the internalization of negative stereotypes among people with severe mental illness. The aim of the present study was to investigate the effectiveness of a group-based anti self-stigma intervention, narrative enhancement and cognitive therapy (NECT) as an add-on to treatment as usual, with regard to changes in self-stigma, self-esteem, and subjective quality of life. After screening for eligibility 106 participants were included in a randomized controlled trial using a wait-list control group, of which 87 completed the study. Assessments were made at baseline, at termination of the intervention, and at a 6-month follow-up (intervention group only). The results showed that NECT was effective in reducing self-stigma and improving self-esteem compared to treatment as usual only. No differences were shown regarding subjective quality of life. Changes shown in the intervention group at termination of intervention were stable at the 6-month follow-up. A regression analysis showed that there was a positive relationship between exposure to the intervention and reduction of self-stigma. The conclusion of the present study is that, using a sample size with adequate power, NECT seems to be an effective intervention with regard to diminishing self-stigma and improving self-esteem, and that these improvements were stable at a 6-month follow-up. There was a distinct relationship between number of sessions attended and improvements in self-stigma and self-esteem controlling for confounding factors. This puts attention to the importance of creating a group climate which facilitate and encourage participation through the various phases of the intervention.

Feeling Better at This Age? Investigating Three Explanations for Self-Rated Health Improvements Among the Oldest-Old.

PubMed

Vogelsang, Eric M

2017-09-08

Although the majority of individuals in their 80s or 90s do not experience improving health, a significant portion of this age group either (a) subjectively assess their health as improving; or (b) demonstrate self-rated health improvements when comparing consecutive surveys. While there is a body of research that examines self-rated health declines in older ages, much less work has studied possible determinants of self-rated health improvements. This is important, since there is increasing evidence that oldest-old adults have unique health evaluative processes that are not yet well-understood. Using 21,155 observations from eight waves of the Asset and Health Dynamics survey (the oldest-old portion of the Health and Retirement Study), I use hierarchical linear models to test three explanations as to why the oldest-old may report or demonstrate self-rated health improvements: (a) normalized pre-existing chronic conditions, (b) positive lifestyle changes, and (c) recovery from recent prior health shocks. Health improvements calculated by comparing consecutive surveys were related to a recovery from four particular serious health diagnoses (cancer, stroke, heart disease, and lung disease). Conversely, explicitly reported health improvements were associated with normalizing pre-existing conditions. Lastly, starting a regular exercise routine was related to both types of health improvements; while the cessation of negative health behaviors (i.e., drinking and smoking) was not related to either type. These results suggest that while subjective health "improvements" among the oldest-old may be a sign of successful aging, they should be interpreted critically and cautiously. © The Author 2017.

2014-02-01

Improving the level of self-management by people undergoing hemodialysis is an effective way to reduce the incidence of mortality and complications and improve quality of life. A better understanding of what influences an individual's level of self-management can help nurses find appropriate ways to improve self-management. To examine self-management levels, and discuss the factors influencing self-management, in a sample of patients undergoing hemodialysis in Beijing. A descriptive study design was chosen. A convenience sample of 216 patients undergoing hemodialysis was recruited from dialysis centers in three tertiary hospitals in Beijing from September 2010 to January 2011. Questionnaires were used to examine the variables: level of self-management; knowledge of hemodialysis; self-efficacy; anxiety and depression; and social support. Data analysis involved descriptive statistics, including frequency, percentage, mean and standard deviations, while Spearman correlation, non-parametric Z and χ(2) and multiple linear regression were used for comparative purposes. The number of returned questionnaires was 198 (91.67% response rate). The overall score of self-management was 56.01 (SD=10.75). The average item scores for each of the four self-management subscales were 3.02 for partnership, 2.98 for problem-solving skills, 2.74 for self-care and 2.47 for emotional management. Multiple linear regression analyses for overall self-management and the four subscales indicated that knowledge, self-efficacy, the availability of social support and depression were the main influencing factors which explained 34.1% of the variance of self-management. The level of self-management by those undergoing hemodialysis in this study was less than ideal, varying from 'rare' to 'sometimes' for use of self-management behaviors. For the different subscales of self-management, partnership was the most used and emotional management the least used strategy. Patients' knowledge, self-efficacy, the availability of social support and depression were the main factors influencing self-management. Copyright © 2013 Elsevier Ltd. All rights reserved.

Nursing clinical practice changes to improve self-management in chronic obstructive pulmonary disease.

Padilha, J M; Sousa, P A F; Pereira, F M S

2018-03-01

To propose nursing clinical practice changes to improve the development of patient self-management. Chronic obstructive pulmonary disease is one of the main causes of chronic morbidity, loss of quality of life and high mortality rates. Control of the disease's progression, the preservation of autonomy in self-care and maintenance of quality of life are extremely challenging for patients to execute in their daily living. However, there is still little evidence to support nursing clinical practice changes to improve the development of self-management. A participatory action research study was performed in a medicine inpatient department and the outpatient unit of a Portuguese hospital. The sample comprised 52 nurses and 99 patients. For data collection, we used interviews, participant observation and content analysis. The main elements of nursing clinical practice that were identified as a focus for improvement measures were the healthcare model, the organization of healthcare and the documentation of a support decision-making process. The specific guidelines, the provision of material to support decision-making and the optimization of information sharing between professionals positively influenced the change process. This change improved the development of self-management skills related to the awareness of the need for 'change', hope, involvement, knowledge and abilities. The implemented changes have improved health-related behaviours and clinical outcomes. To support self-management development skills, an effective nursing clinical practice change is needed. This study has demonstrated the relevance of a portfolio of techniques and tools to help patients adopt healthy behaviours. The involvement and participation of nurses and patients in the conceptualization, implementation and evaluation of policy change are fundamental issues to improve the quality of nursing care and clinical outcomes. © 2017 International Council of Nurses.

2016-01-01

We investigated the influence of negative emotion on the degree of self-reference effect using event-related potentials (ERPs). We presented emotional pictures and self-referential stimuli (stimuli that accelerate and improve processing and improve memory of information related to an individual’s self-concept) in sequence. Participants judged the color of the target stimulus (self-referential stimuli). ERP results showed that the target stimuli elicited larger P2 amplitudes under neutral conditions than under negative emotional conditions. Under neutral conditions, N2 amplitudes for highly self-relevant names (target stimulus) were smaller than those for any other names. Under negative emotional conditions, highly and moderately self-referential stimuli activated smaller N2 amplitudes. P3 amplitudes activated by self-referential processing under negative emotional conditions were smaller than neutral conditions. In the left and central sites, highly self-relevant names activated larger P3 amplitudes than any other names. But in the central sites, moderately self-relevant names activated larger P3 amplitudes than non-self-relevant names. The findings indicate that negative emotional processing could weaken the degree of self-reference effect. PMID:27733836

A patient-centered quality improvement program implemented in one Virginia hemodialysis facility sought to determine if peer-to-peer (P2P) programs can assist patients on in-center hemodialysis with self-management and improve outcomes. Using a single-arm, repeatedmeasurement, quasi-experimental design, 46 patients participated in a four-month P2P intervention. Outcomes include knowledge, self-management behaviors, and psychosocial health indicators: self-efficacy, perceived social support, hemodialysis social support, and healthrelated quality of life (HRQoL). Physiological health indicators included missed and shortened treatments, arteriovenous fistula placement, interdialytic weight gain, serum phosphorus, and hospitalizations. Mentees demonstrated increased knowledge, self-efficacy, perceived social support, hemodialysis social support, and HRQoL. Missed treatments decreased. Mentors experienced increases in knowledge, self-management, and social support. A P2P mentoring program for in-center hemodialysis can benefit both mentees and mentors.

Gregory, Paul AM; Chiu, Stephanie

2008-01-01

Objective To examine whether self-assessment and reflection-in-action improves critical thinking among pharmacy students. Methods A 24-item standardized test of critical thinking was developed utilizing previously-validated questions. Participants were divided into 2 groups (conditions). Those in condition 1 completed the test with no interference; those in condition 2 completed the test but were prompted at specific points during the test to reflect and self-assess. Results A total of 94 undergraduate (BScPhm) pharmacy students participated in this study. Significant differences (p < 0.05) were observed between those who completed the test under condition 1 and condition 2, suggesting reflection and self-assessment may contribute positively to improvement in critical thinking. Conclusions Structured opportunities to reflect-in-action and self-assess may be associated with improvements among pharmacy students in performance of tasks related to critical thinking.

Research suggests that treatments for depression among individuals with chronic physical disease do not improve disease outcomes significantly, and chronic disease management programs do not necessarily improve mood. For individuals experiencing co-morbid depression and chronic physical disease, demands on the self-regulation system are compounded, leading to a rapid depletion of self-regulatory resources. Because disease and depression management are not integrated, patients lack the understanding needed to prioritize self-regulatory goals in a way that makes disease and depression management synergistic. A framework in which the management of co-morbidity is considered alongside the management of either condition alone offers benefits to researchers and practitioners and may help improve clinical outcomes.

Sjoegren-Larsson syndrome (SLS) is a rare, autosomal recessive disorder that is characterized by congenital ichthyosis, mental retardation, and spastic diplegia or tetraplegia. Three United States families, three Egyptian families, and one Israeli Arab family were investigated for linkage of the SLS gene to a region of chromosome 17. Pairwise and multipoint linkage analysis with nine markers mapped the SLS gene to the same region of the genome as that reported in Swedish SLS pedigrees. Examination of recombinants by haplotype analysis showed that the gene lies in the region containing the markers D17S953, D17S805, D17S689, and D17S842. D17S805 is pericentromeric onmore » 17p. Patients in two consanguineous Egyptian families were homozygous at the nine marker loci tested, and another patient from a third family was homozygous for eight of the nine, suggesting that within each of these families the region of chromosome 17 carrying the SLS gene is identical by descent. Linkage of the SLS gene to chromosome 17p in families of Arabic, mixed European, Native American, and Swedish descent provides evidence for a single SLS locus and should prove useful for diagnosis and carrier detection in worldwide cases. 25 refs., 4 figs., 1 tab.« less

The aim of this study was to evaluate the clinical and epidemiological profile of hair and scalp disorders in children referred to the Pediatric Dermatology Outpatient Clinic. We performed a retrospective study of children with hair loss problems or scalp diseases who turned to the Pediatric Dermatology Service, Anna Meyer Pediatric Hospital, Florence, Italy, from January 1, 2009, to December 31, 2009. Demographics, personal and familial medical history, laboratory tests, clinical examination, final diagnosis and therapeutic interventions were obtained from the manual chart review. Of the 2,640 children who had access to the Pediatric Dermatology Service, 190 (7.19%) had a hair or scalp disorder. Among the 190 children, 60 (31.57%) presented with nonscarring alopecia, 56 (29.47%) had benign neoplasias, hamartomas or vascular malformations of the scalp, 51 (26.84%) had scalp inflammatory diseases, 14 (7.36%) had scarring alopecia, 5 (2.63%) had infections and 2 (1.05%) had infestation of the scalp. A case of constitutional hypertrichosis (0.52%) and also a case (0.52%) of lamellar ichthyosis were diagnosed. Our results underline that hair and scalp diseases represent an important percentage of admittances to a dermatological pediatric outpatient clinic. The variety and complexity of the diseases observed in this study included diseases commonly found also in adulthood. © 2015 S. Karger AG, Basel.

Peeling skin syndrome (PSS) is a rare form of ichthyosis with a probable autosomal recessive inheritance that exhibits superficial, painless, continual, or seasonal cutaneous exfoliation. The syndrome generally appears at birth or in infancy. We report a case of generalized PSS and provide a literature review. A 34-year-old woman reported a lifelong history of generalized and painless peeling of the skin that worsened in summer. Her parents were third degree cousins. Her twin sister and her two cousins presented with the same condition. Physical examination showed widespread superficial sheets of variable size that could be easily removed without bleeding or pain. No underlying erythema was noted. Otherwise, the patient was in good health. Histological findings showed an epidermal cleavage within the stratum corneum. The generalized form of PSS is classified into 3 types, A, B, and C, according to the classification system of Traupe and Mevorah. We have tried to classify the cases of generalized PSS already reported in the literature into one of these three types. Thirteen reported cases probably presented PSS-type A. Sixteen patients are best described as PSS-type B. Two patients exhibit PSS-type C. Fifteen reported patients had an acral form of peeling skin syndrome. The classification of the eleven remaining patients was difficult to determine. Our patient presented clinical and histological features of generalized PSS-type A.

Netherton syndrome (NS [MIM 256500]) is a rare and severe autosomal recessive disorder characterized by congenital ichthyosis, a specific hair-shaft defect (trichorrhexis invaginata), and atopic manifestations. Infants with this syndrome often fail to thrive; life-threatening complications result in high postnatal mortality. We report the assignment of the NS gene to chromosome 5q32, by linkage analysis and homozygosity mapping in 20 families affected with NS. Significant evidence for linkage (maximum multipoint LOD score 10.11) between markers D5S2017 and D5S413 was obtained, with no evidence for locus heterogeneity. Analysis of critical recombinants mapped the NS locus between markers D5S463 and D5S2013, within an <3.5-cM genetic interval. The NS locus is telomeric to the cytokine gene cluster in 5q31. The five known genes encoding casein kinase Iα, the α subunit of retinal rod cGMP phosphodiesterase, the regulator of mitotic-spindle assembly, adrenergic receptor β2, and the diastrophic dysplasia sulfate–transporter gene, as well as the 38 expressed-sequence tags mapped within the critical region, are not obvious candidates. Our study is the first step toward the positional cloning of the NS gene. This finding promises a better understanding of the molecular mechanisms that control epidermal differentiation and immunity.

The process by which the periderm transitions to stratified epidermis with the establishment of the skin barrier is unknown. Understanding the cellular and molecular processes involved is crucial for the treatment of human pathologies, where abnormal skin development and barrier dysfunction are associated with hypothermia and perinatal dehydration. For the first time, we demonstrate that retinoic acid (RA) levels are important for periderm desquamation, embryonic skin differentiation and barrier formation. Although excess exogenous RA has been known to have teratogenic effects, little is known about the consequences of elevated endogenous retinoids in skin during embryogenesis. Absence of cytochrome P450, family 26, subfamily b, polypeptide 1 (Cyp26b1), a retinoic-acid-degrading enzyme, results in aberrant epidermal differentiation and filaggrin expression, defective cornified envelopes and skin barrier formation, in conjunction with peridermal retention. We show that these alterations are RA dependent because administration of exogenous RA in vivo and to organotypic skin cultures phenocopy Cyp26b1−/− skin abnormalities. Furthermore, utilizing the Flaky tail (Ft/Ft) mice, a mouse model for human ichthyosis, characterized by mutations in the filaggrin gene, we establish that proper differentiation and barrier formation is a prerequisite for periderm sloughing. These results are important in understanding pathologies associated with abnormal embryonic skin development and barrier dysfunction. PMID:22366455

Conradi-Hünermann-Happle [X-linked dominant chondrodysplasia punctata 2 (CDPX2)] syndrome is a rare X-linked dominant skeletal dysplasia usually lethal in men while affected women show wide clinical heterogeneity. Different EBP mutations have been reported. Severe female cases have rarely been reported, with only six antenatal presentations. To better characterize the phenotype in female fetuses, we included nine antenatally diagnosed cases of women with EBP mutations. All cases were de novo except for two fetuses with an affected mother and one case of germinal mosaicism. The mean age at diagnosis was 22 weeks of gestation. The ultrasound features mainly included bone abnormalities: shortening (8/9 cases) and bowing of the long bones (5/9), punctuate epiphysis (7/9) and an irregular aspect of the spine (5/9). Postnatal X-rays and examination showed ichthyosis (8/9) and epiphyseal stippling (9/9), with frequent asymmetric short and bowed long bones. The X-inactivation pattern of the familial case revealed skewed X-inactivation in the mildly symptomatic mother and random X-inactivation in the severe fetal case. Differently affected skin samples of the same fetus revealed different patterns of X-inactivation. Prenatal detection of asymmetric shortening and bowing of the long bones and cartilage stippling should raise the possibility of CPDX2 in female fetuses, especially because the majority of such cases involve de novo mutations. © 2015 John Wiley & Sons, Ltd.

Recommendations to improve self-management support and health outcomes for people with chronic conditions in primary care settings are provided on the basis of expert opinion supported by evidence for practices and processes. Practices and processes that could improve self-management support in primary care were identified through a nominal group process. In a targeted search strategy, reviews and meta-analyses were then identifed using terms from a wide range of chronic conditions and behavioral risk factors in combination with Self-Care, Self-Management, and Primary Care. On the basis of these reviews, evidence-based principles for self-management support were developed. The evidence is organized within the framework of the Chronic Care Model. Evidence-based principles in 12 areas were associated with improved patient self-management and/or health outcomes: (1) brief targeted assessment, (2) evidence-based information to guide shared decision-making, (3) use of a nonjudgmental approach, (4) collaborative priority and goal setting, (5) collaborative problem solving, (6) self-management support by diverse providers, (7) self-management interventions delivered by diverse formats, (8) patient self-efficacy, (9) active followup, (10) guideline-based case management for selected patients, (11) linkages to evidence-based community programs, and (12) multifaceted interventions. A framework is provided for implementing these principles in three phases of the primary care visit: enhanced previsit assessment, a focused clinical encounter, and expanded postvisit options. There is a growing evidence base for how self-management support for chronic conditions can be integrated into routine health care.

Biomaterials that promote the self-renewal ability and differentiation capacity of neural stem cells (NSCs) are desirable for improving stem cell therapy to treat neurodegenerative diseases. Incorporation of micro- and nanoparticles into stem cell culture has gained great attention for the control of stem cell behaviors, including proliferation and differentiation. In this study, ferritin, an iron-containing natural protein nanoparticle, was applied as a biomaterial to improve the self-renewal and differentiation of NSCs and neural progenitor cells (NPCs). Ferritin nanoparticles were added to NSC or NPC culture during cell growth, allowing for incorporation of ferritin nanoparticles during neurosphere formation. Compared to neurospheres without ferritin treatment, neurospheres with ferritin nanoparticles showed significantly promoted self-renewal and cell-cell interactions. When spontaneous differentiation of neurospheres was induced during culture without mitogenic factors, neuronal differentiation was enhanced in the ferritin-treated neurospheres. In conclusion, we found that natural nanoparticles can be used to improve the self-renewal ability and differentiation potential of NSCs and NPCs, which can be applied in neural tissue engineering and cell therapy for neurodegenerative diseases.

To evaluate the efficacy of a nutrition education intervention for college female athletes to improve nutrition knowledge, build self-efficacy with respect to making healthful dietary choices, and improve dietary intake. A pretest-posttest control group design was implemented. A women's soccer team (n =15) and a women's swim team (n = 15) were randomly assigned to experimental and control groups, respectively. The intervention focused on nutrition knowledge, self-efficacy in making healthful dietary choices, and dietary practices to demonstrate treatment effect. Dependent variables were nutrition knowledge, self-efficacy, and dietary practices. Independent variables were group assignment. The Mann-Whitney U test was used to analyze the results between groups, and the Fisher exact probability test was used to detect differences between groups in the number of positive dietary changes. Treatment participants significantly improved nutrition knowledge, self-efficacy (P <.05), and the overall number of positive dietary changes (P <.03). This study reduces the paucity of nutrition education intervention research among athletes and demonstrates the ability to increase not only nutrition knowledge, which is typically reported, but also self-efficacy and improvement in overall positive dietary changes during an 8-week intervention.

Boost Your Body: Self-Improvement Magazine Messages Increase Body Satisfaction in Young Adults.

Veldhuis, Jolanda; Konijn, Elly A; Knobloch-Westerwick, Silvia

2017-02-01

The verbal messages that contextualize exposure to idealized body imagery may moderate media users' body satisfaction. Such contextualizing verbal messages often take the form of social comparison motives in fashion magazines, while body dissatisfaction is an important mechanism underlying various body image-related health issues like depression and unbalanced weight status. Hence, the present study applied social comparison motives as induced through magazine cover messages. Hypotheses were tested in an experimental design with social comparison motives (self-improvement vs. self-evaluation vs. control) and recipient gender as between-subjects factors and body satisfaction as within-subjects factor (N = 150). Results showed that self-improvement messages accompanying ideal body media models increased body satisfaction, compared to control messages and baseline measures. In contrast, the self-evaluation messages did not impact body satisfaction. Results imply that inconsistencies regarding effects from exposure to idealized body imagery are explained by the context in which media images are portrayed, evoking differential social comparison motives. Moreover, the findings imply that health communication interventions can use verbal messages on body improvement as helpful tools, if they draw on social comparison motives effectively.

Teaching Self-concept and Self-esteem in a Clinical Communications Course

PubMed Central

2006-01-01

Effective interpersonal communication skills are needed for pharmacists to deliver patient-centered care. To achieve this outcome with pharmacists, communication skills are emphasized in pharmacy school in required coursework, such as a clinical communication course. One important concept to include in communication coursework is content on perceptions because perceptions influence communication interactions. Specific emphasis should include a focus on self-perceptions and self-concept, because related empirical literature demonstrates that accurate academic self-concepts predict academic success. These results were extrapolated to a pharmacy clinical communications course where a lecture and laboratory series was designed to emphasize self-concept and facilitate communication skills improvement. The instructional design of this series promoted the advancement of students’ communication skills by using communication inventories, self-reflection activities, peer and class discussion, and lecture content. Class discussions, self-reflections, and baseline, and follow-up counseling activities throughout the semester provided evidence of improvements. PMID:17149428

To determine the impact of the Fit Families youth weight management program on self-perception of participants. Fit Families was delivered through Cooperative Extension and provided education to overweight and obese children and their families on healthful eating and physical activity along with building self-esteem and social competence. At the beginning and end of the 7-week program, a convenience sample of 46 youth completed the Self-Perception Profile for Children questionnaire to evaluate changes in self-perception. Youth had improved self-perception in the areas of athletic competence (P = .04) and physical appearance (P = .007) after participating in Fit Families. Fit Families provides a holistic approach to weight management that promotes positive self-perception, which may decrease the burden of depression, anxiety, and low self-esteem obese youth face.

The effect of ankle-foot orthoses on self-reported balance confidence in persons with chronic poststroke hemiplegia.

PubMed

Zissimopoulos, Angelika; Fatone, Stefania; Gard, Steven

2014-04-01

One intervention often used to address physical impairments post stroke is an ankle-foot orthosis. Ankle-foot orthoses may improve walking speed, stride length, and gait pattern. However, effects on balance, crucial for safe ambulation, are thus far inconclusive. One aspect of balance shown to contribute to functional ability is self-efficacy. Self-efficacy, defined as the belief in one's ability to succeed in particular situations, has been shown to be more strongly associated with activity and participation (as defined by the International Classification of Functioning, Disability, and Health) than physical performance measures of gait or balance. We investigated whether self-efficacy, or balance confidence when referred to in the context of balance capabilities, is improved with ankle-foot orthosis use. Repeated measures study design. Balance confidence was measured using the Activities-specific Balance Confidence Scale in 15 persons with chronic poststroke hemiplegia, with and without their regular ankle-foot orthosis. Activities-specific Balance Confidence Scale scores were significantly higher (p ≤ 0.01) for the ankle-foot orthosis condition compared to no ankle-foot orthosis. One mechanism by which ankle-foot orthosis use may influence balance is improved balance confidence. Future work should explore the specific mechanisms underlying this improvement in self-efficacy. Clinical relevance Self-efficacy may be an important factor to consider when evaluating functioning post stroke. Rehabilitative interventions that improve balance confidence may help restore participation and overall functioning in pathological populations, particularly in the fall-prone poststroke population. Study results provide evidence for improvements in balance confidence with ankle-foot orthosis use.

Depression and severe psychological distress are frequently comorbid with diabetes and are associated with reduced adherence to medication and healthy lifestyle regimens, poorer glycemic control, and increased complications. The mixed success of existing treatments for depression in diabetes patients suggests a need for supplementary approaches to this common problem. This article reviews recent evidence for the benefits of self-compassion in chronically ill patients, suggesting its utility as a clinical tool for improving self-care, depression, and glycemic control in diabetes. Possible physical and psychological pathways by which self-compassion may promote better outcomes in diabetes patients are considered, with particular attention given to reductions in negative self-judgment and improved motivation to undertake self-care.

To test the effectiveness of an intervention delivered by health professionals outside the school environment to girls identified with issues such as poor body image, low self-esteem, low self-confidence, nonparticipation in sports, or being overweight or underweight. The study's design was a stepped-wedge randomized controlled trial to test the efficacy of an intervention on self-esteem, impairment induced by eating disorders, self-efficacy, body satisfaction, and dieting behaviors. The study took place at the community health center located in a culturally diverse area of Melbourne, Victoria, Australia. Participants were 122 primary and secondary school girls between 10 and 16 years of age. Girls on the Go! is a 10-week program designed to improve self-esteem, body image, and confidence, using an empowerment model that involved interactive and experiential learning approaches. Weekly themes included body image and self-esteem, safety and assertiveness, a healthy mind, physical activity, healthy eating, trust and confidence, and connections. Measurements were made using Rosenberg Self-Esteem Scale, clinical interview assessment, health self-efficacy (included mental health and physical health self-efficacy scales), body esteem scale, and the Dutch Eating Behavior Questionnaire for Children. A linear mixed model was used. The intervention led to a significant increase (p < .05) in self-esteem and self-efficacy (mental and physical health self-efficacy subscales), for both primary and secondary school-aged participants and reduced dieting behaviors (secondary school participants). These gains were retained after 6 months of follow-up. This group-based, low-dose intervention, which, although targeting girls with a range of psychological issues and including both overweight and underweight participants, is a successful means of improving self-esteem among girls from diverse cultural backgrounds. © The Author(s) 2016.

Twelve patients complaining of chronic free-floating anxiety, usually also with panic attacks, were assigned at random to treatment by six hour-long sessions of anxiety-management training, either with positive or with negative self-statements, given over six weeks. Patients in both treatment conditions improved, with a small trend favouring positive over negative self-instruction, especially at follow-up. It is unclear how much self-instruction, rather than therapeutic attention or mere passage of time, accounted for the bulk of the modest improvement obtained.

A new injection-controlled laser resonator incorporates self-filtering and self-imaging characteristics with an efficient injection scheme. A low-divergence laser signal is injected into the resonator, which enables the injection signal to be converted to the desired resonator modes before the main laser pulse starts. This injection technique and resonator design enable the laser cavity to improve the quality of the injection signal through self-filtering before the main laser pulse starts. The self-imaging property of the present resonator reduces the cavity induced diffraction effects and, in turn, improves the laser beam quality. 5 figs.

Immunosuppressive medication non-adherence is one of the most prevalent but preventable causes of poor outcomes in adult renal transplant recipients, yet there is a paucity of studies testing interventions in this area. Using a randomized controlled trial design, 30 adult renal transplant recipients were screened for medication non-adherence using electronic monitoring. Fifteen non-adherent participants were randomized to receive either a continuous self-improvement intervention or attention control management. The six-month continuous self-improvement intervention involved the participant and clinical nurse specialist collaboratively identifying the person's life routines, important people, and possible solutions to enhance medication taking. The participant then received individual monthly medication taking feedback delivered via a graphic printout of daily medication taking generated from electronic monitoring. The mean medication adherence score for the continuous self-improvement intervention group (n = 8) was statistically significantly higher than the attention control group's (n = 5) mean medication adherence score (p = 0.03). The continuous self-improvement intervention effect size (Cohen's d) was large at 1.4. Participants' perceptions of the intervention were highly favorable. The continuous self-improvement intervention shows promise as an effective and feasible approach to improve medication adherence in adult renal transplant recipients. A fully-powered study with a diverse sample is needed to confirm these preliminary findings. © 2010 John Wiley & Sons A/S.

Monitoring, metacognition, and executive function: elucidating the role of self-reflection in the development of self-regulation.

PubMed

Lyons, Kristen E; Zelazo, Philip David

2011-01-01

While an abundance of research has investigated the development of the automatic and controlled processes through which individuals control their thoughts, emotions, and actions, less research has emphasized the role of the self in self-regulation. This chapter synthesizes four literatures that have examined the mechanisms through which the individual acts in a managerial role, evaluating the current status of the system and initiating regulatory actions as necessary. Taken together, these literatures (on executive function, error monitoring, metacognition, and uncertainty monitoring) suggest that self-reflection plays a critical role in self-regulation, and that developmental improvements in self-reflection (via increasing levels of conscious awareness and enhanced calibration of monitoring systems) may serve as driving forces underlying developmental improvement (and temperamental individual differences) in children's ability to control their thoughts and actions.

Background: Mutations leading to changes in properties, regulation, or expression of connexin-made channels have been implicated in 28 distinct human hereditary diseases. Eight of these result from variants of connexin 26 (Cx26), a protein critically involved in cell-cell signaling in the inner ear and skin. Lack of non-toxic drugs with defined mechanisms of action poses a serious obstacle to therapeutic interventions for diseases caused by mutant connexins. In particular, molecules that specifically modulate connexin hemichannel function without affecting gap junction channels are considered of primary importance for the study of connexin hemichannel role in physiological as well as pathological conditions. Monoclonal antibodies developed in the last three decades have become the most important class of therapeutic biologicals. Recombinant methods permit rapid selection and improvement of monoclonal antibodies from libraries with large diversity. Methods: By screening a combinatorial library of human single-chain fragment variable (scFv) antibodies expressed in phage, we identified a candidate that binds an extracellular epitope of Cx26. We characterized antibody action using a variety of biochemical and biophysical assays in HeLa cells, organotypic cultures of mouse cochlea and human keratinocyte-derived cells. Results: We determined that the antibody is a remarkably efficient, non-toxic, and completely reversible inhibitor of hemichannels formed by connexin 26 and does not affect direct cell-cell communication via gap junction channels. Importantly, we also demonstrate that the antibody efficiently inhibits hyperative mutant Cx26 hemichannels implicated in autosomal dominant non-syndromic hearing impairment accompanied by keratitis and hystrix-like ichthyosis-deafness (KID/HID) syndrome. We solved the crystal structure of the antibody, identified residues that are critical for binding and used molecular dynamics to uncover its mechanism of action. Conclusions: Although further studies will be necessary to validate the effect of the antibody in vivo, the methodology described here can be extended to select antibodies against hemichannels composed by other connexin isoforms and, consequently, to target other pathologies associated with hyperactive hemichannels. Our study highlights the potential of this approach and identifies connexins as therapeutic targets addressable by screening phage display libraries expressing human randomized antibodies.

The objective of this paper was to evaluate a chronic care management program piloted by a visiting nurses association. Desired outcomes were to increase nurses' knowledge of self-management of chronic conditions and improve patient self-efficacy and clinical measures. The program provided educational development for nurses and piloted encounters with patients with chronic conditions targeting community health nurses for a chronic care professional (CCP) certification and invited 300 faith community nurses to an education program on chronic condition(s). Thirteen patients with chronic condition(s) were enrolled. Chronic care professional modules were used to increase nurses' knowledge and were measured by successful completion of a certification exam. Faith community nurses participated in an education program and completed a posttest to measure knowledge of content. Patient improvement in self-management was measured by pre- and postintervention self-efficacy scores and clinical measures. Seventeen nurses successfully completed the exam, and 38 faith community nurses participated in the program and completed the posttest. Three patients showed improvement in self-efficacy scores and eight in clinical measures. The educational development of community nurses prepared them to provide effective encounters to improve self-efficacy and clinical outcomes for older adults with chronic conditions. © 2013 Wiley Periodicals, Inc.

Interventions based on self-management of well-being theory: pooling data to demonstrate mediation and ceiling effects, and to compare formats.

Goedendorp, M M; Steverink, N

2017-09-01

Interventions based on self-management of well-being (SMW) theory have shown positive effects, but additional questions remain: (1) Are improvements in well-being, as induced by the interventions, mediated by improved self-management ability (SMA)? (2) Do the interventions show ceiling effects? (3) Is a particular format of SMW intervention (individual, group, or self-help) more effective? Data of three randomized controlled trials were pooled. The greater part of the sample (N = 445) consisted of single older females. A bootstrap analysis was performed to test for mediation. Regression analyses with interaction effects were performed to test for ceiling effects. Controlled and transformed effect sizes (proportion of maximum change) were calculated to compare formats. There was a full significant mediation of well-being by SMA. A significant interaction (ceiling) effect was found on well-being, but not on SMA. The controlled effect sizes of the raw scores were small to medium (.04-.49), and were small to large after transformation (.41-.73). None of the intervention formats was more effective. Support for SMW theory was found, i.e. increasing self-management ability lead to improved well-being. Some ceiling effect was found. We conclude that various SMW interventions formats can improve self-management abilities and well-being with medium effects.

Improving self-perception and self-efficacy in patients with spinal cord injury: the efficacy of DVD-based instructions.

We assessed the effects of a spinal cord injury home rehabilitation DVD on patients with spinal cord injury. Multimedia have been used widely in health care in the digital age. The provision of rehabilitation instructions is a major responsibility of the rehabilitation staff. This study adopted a quasi-experimental pretest-posttest control group design. We collected data from a rehabilitation nursing ward at a medical centre between October 2011-April 2012. The participants were recruited before being discharged from the hospital. The experimental group (n = 28) received multimedia DVD instructions for three months, in addition to teaching sessions conducted by the researcher, whereas the control group (n = 31) received instructions without a DVD. Both groups completed the self-perception and self-efficacy scales used in this study before and after the intervention. The results indicated that, after the multimedia DVD intervention, the experimental group exhibited a considerably greater improvement in self-perception than did the control group. Although we recorded increased scores for both self-perception and self-efficacy for both groups, no marked differences emerged between the control and the intervention groups by using a generalised estimating equation. These results suggest that the home rehabilitation DVD is an effective instrument for improving self-perception and self-efficacy in patients with spinal cord injury. However, monitoring these patients over the long term is necessary. Our study results confirmed that the spinal cord injury home rehabilitation DVD is a practical health education tool. We plan to use the proposed DVD intervention with a larger number of hospitalised patients, and to continuously monitor their improvement. © 2015 John Wiley & Sons Ltd.

Obesity in Children and the 'Myth of Psychological Maladjustment': Self-Esteem in the Spotlight.

PubMed

Hill, Andrew J

2017-03-01

There are contrasting views regarding the psychological well-being of children with obesity. Responding to limitations of existing evidence, Jane Wardle in 2005 argued for a 'myth of psychological maladjustment'. This review looks again at self-esteem. The different characterisations of self-esteem each offer value. Global self-esteem is reduced in nearly all studies of youth with obesity. Dimensional self-esteem reveals physical appearance, athletic and social competence as the most affected areas, confirmed by research that has operationalised low self-competence. Children with obesity are also more likely to be victimised by their peers, generally and for their fatness. Victims who bully others appear to preserve some aspects of self-esteem. A relatively small proportion of youth with obesity has low self-esteem, but those with severe and persistent obesity are especially compromised. Weight loss is only weakly associated with improved self-competence suggesting the value of resilience and asset approaches to improving well-being.

2013-01-01

Lack of physical activity has contributed to the nation's childhood obesity crisis, but the impact of physical activity on self-efficacy as a mediator of behavior change has not been examined. This systematic review (SR) describes the published evidence related to the impact of physical activity intervention programs on self-efficacy among youths. From January 2000 to June 2011, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards were used to identify publications from PubMed, PsychInfo, Web of Knowledge, and the Cochran Database of Systematic Reviews. The Cochrane Population, Intervention, Control, Outcome, Study Design (PICOS) approach guided this SR articles selection and evaluation process. Of the 102 publications screened, 10 original studies matched the SR inclusion criteria. The types of physical activity interventions and self-efficacy assessments for these 10 studies were diverse. Of the 10 included articles, 6 articles identified an improvement in post-self-efficacy assessments compared to baseline and 4 showed no effect. In conclusion, physical activity intervention programs may improve self-efficacy in youths. A standardized approach to classify and measure self-efficacy is required. Further research is needed to quantify the association of self-efficacy ratings after completing physical activity interventions with objective health improvements, such as weight loss.

2012-01-01

To evaluate effectiveness of a face-to-face and an online fatigue self-management programme and to compare these to two control groups (information-only and no-intervention) in a sample of adults (n = 115) with neurological conditions reporting extreme fatigue. Non-equivalent pre-test post-test control group design using the Fatigue Impact Scale, Personal Wellbeing Index and Activity Card Sort as primary outcome measures. Participants in the two intervention groups and the information-only group showed clinically significant improvements in fatigue over time (p < 0.05). When compared to the no-intervention group, face-to-face participants showed significantly greater improvement in overall and cognitive fatigue, while participants in the online group showed significant improvement in self-efficacy and stress. Participation in either the online or face-to-face programme appears to result in improved self-management, however, with different potency depending on outcomes. The improvement in the online information only group further complicates the understanding of the results. With few other comparisons of online and face-to-face self-management protocols available, further research is needed to understand differential impacts which may be related to the delivery format, the rural versus urban split of participants or other unknown factors.

Food safety educational intervention positively influences college students' food safety attitudes, beliefs, knowledge, and self-reported practices.

2009-01-01

In this study, the authors evaluated college students' food safety attitudes, beliefs, knowledge, and self-reported practices and explored whether these variables were positively influenced by educational intervention. Students (n=59), were mostly seniors, health or non-health majors, and responsible for meal preparation. Subjects completed a food safety questionnaire (FSQ) prior to educational intervention, which consisted of three interactive modules. Subjects completed module pre-, post-, and post-posttests. The FSQ was also administered after exposure to intervention and five weeks later to determine changes in food safety attitudes, beliefs, knowledge, and self-reported practices. Students' FSQ attitude scores increased from 114 to 122 (p < or = .001); FSQ belief and knowledge scores improved from 86 to 98 (p < or = .001) and from 11 to 13 (p < or = .001), respectively. Food safety knowledge was also measured by module pre- and posttests, and improved significantly after intervention for all students, with health majors having the greatest increase. Intervention resulted in improved food safety self-reported practices for health majors only. The educational intervention appeared effective in improving food safety beliefs and knowledge. For health majors, attitudes and some self-reported practices improved. For all areas, the strongest effects were seen in health majors.

Objectives To evaluate the feasibility of a quality improvement programme aimed to enhance the client-centeredness, effectiveness and transparency of physiotherapy services by addressing three feasibility domains: (1) acceptability of the programme design, (2) appropriateness of the implementation strategy and (3) impact on quality improvement. Design Mixed methods study. Participants and setting 64 physiotherapists working in primary care, organised in a network of communities of practice in the Netherlands. Methods The programme contained: (1) two cycles of online self-assessment and peer assessment (PA) of clinical performance using client records and video-recordings of client communication followed by face-to-face group discussions, and (2) clinical audit assessing organisational performance. Assessment was based on predefined performance indicators which could be scored on a 5-point Likert scale. Discussions addressed performance standards and scoring differences. All feasibility domains were evaluated qualitatively with two focus groups and 10 in-depth interviews. In addition, we evaluated the impact on quality improvement quantitatively by comparing self-assessment and PA scores in cycles 1 and 2. Results We identified critical success features relevant to programme development and implementation, such as clarifying expectations at baseline, training in PA skills, prolonged engagement with video-assessment and competent group coaches. Self-reported impact on quality improvement included awareness of clinical and organisational performance, improved evidence-based practice and client-centeredness and increased motivation to self-direct quality improvement. Differences between self-scores and peer scores on performance indicators were not significant. Between cycles 1 and 2, scores for record keeping showed significant improvement, however not for client communication. Conclusions This study demonstrated that bottom-up initiatives to improve healthcare quality can be effective. The results justify ongoing evaluation to inform nationwide implementation when the critical success features are addressed. Further research is necessary to explore the sustainability of the results and the impact on client outcomes in a full-scale study. PMID:28188156

Issue addressed Musculoskeletal conditions are highly prevalent, affecting 28% of the Australian population. Given the persistent nature of many musculoskeletal conditions self-management is recognised as an important aspect of effective disease management. However, participant recruitment and retention for formal self-management programs is a challenge. Methods Arthritis SA (Arthritis Foundation of South Australia, a non-profit community health organisation) redesigned a shorter, community-orientated self-management education program delivered by health professionals. The program utilises aspects of the Stanford model of chronic disease self-management and motivational interviewing as well as principles of adult learning to create an effective learning environment. The program aims to guide participants to learn and practise a range of pain management strategies that are known to be effective in improving quality of life. This study used a pre- and post-test (at 6 weeks) design to determine whether this program achieved benefits in self-reported health outcomes. Outcomes that were measured included pain, fatigue, health distress, self-efficacy and communication. Results A response rate of 47% (n=102) was achieved and small but statistically significant improvements in mean [s.d.] pain scores (6.1 [2.3] to 5.4 [2.4], P=0.001), health distress (2.3 [1.3] to 2.0 [1.3], P=0.002) and self-efficacy (6.2 [2.1] to 6.8 [2.2], P=0.002) were found. Conclusion Community-based participants of this shorter, focused program recorded small but significant improvements in self-reported pain, health distress and self-efficacy. For those who completed the current program, Arthritis SA is currently exploring the potential of developing a booster session to promote sustainable positive health outcomes. So what? Supporting self-management through education is recognised as important but also as a key challenge for effective management of musculoskeletal conditions. Using a pre-post evaluation design, this study demonstrated effectiveness (short-term improvements for self-reported pain, health distress and self-efficacy) for a redesigned and shortened community-targeted program focusing on musculoskeletal pain.

Shared care dyadic intervention: outcome patterns for heart failure care partners.

PubMed

Sebern, Margaret D; Woda, Aimee

2012-04-01

Up to half of heart failure (HF) patients are readmitted to hospitals within 6 months of discharge. Many readmissions are linked to inadequate self-care or family support. To improve care, practitioners may need to intervene with both the HF patient and family caregiver. Despite the recognition that family interventions improve patient outcomes, there is a lack of evidence to support dyadic interventions in HF. Thus, the purpose of this study was to test the Shared Care Dyadic Intervention (SCDI) designed to improve self-care in HF. The theoretical base of the SCDI was a construct called Shared Care. Shared Care represents a system of processes used in family care to exchange support. Key findings were as follows: the SCDI was acceptable to both care partners and the data supported improved shared care for both. For the patient, there were improvements in self-care. For the caregivers, there were improvements in relationship quality and health.

This systematic review aimed to generate patient-focussed recommendations to enhance support of heart failure self-care by examining patients' experiences, perspectives and self-care behaviours. Despite increased recognition of the importance of heart failure self-care, patients' knowledge and practices around this self-care and interventions to improve it are inconsistent. Consequently, current guidelines focus on what the domains of heart failure self-care are, more so than the ways to improve this care. Systematic review and qualitative interpretive synthesis. A systematic, comprehensive and detailed search of 11 databases was conducted until March, 2012 for papers published 1995-2012: 37 studies were included (1343 patients, 75 caregivers, 63 health care professionals) that contained a qualitative research component and data on adult patients' heart failure self-care. This interpretive synthesis used a recognized approach consisting of a multi-stage analytic process; in addition, the included studies underwent quality appraisal. Findings indicate that while patients could often recall health professionals' self-care advice, they were unable to integrate this knowledge into daily life. Attempts to manage HF were based on how patients 'felt' rather than clinical indicators of worsening symptoms. Self-efficacy and learning from past management experiences facilitated favourable outcomes - these enabled patients and caregivers to adeptly apply self-care strategies into daily activities. Addressing common but basic knowledge misconceptions regarding the domains of HF self-care is insufficient to increase effective HF self-care; this should be supplemented with strategies with patients and family members to promote self-efficacy, learning and adaptation/application of recommendations to daily life. © 2015 John Wiley & Sons Ltd.

Self-esteem treatment in anxiety: A randomized controlled crossover trial of Eye Movement Desensitization and Reprocessing (EMDR) versus Competitive Memory Training (COMET) in patients with anxiety disorders.

Little is known about treating low self-esteem in anxiety disorders. This study evaluated two treatments targeting different mechanisms: (1) Eye Movement Desensitization and Reprocessing (EMDR), which aims to desensitize negative memory representations that are proposed to maintain low self-esteem; and (2) Competitive Memory Training (COMET), which aims to activate positive representations for enhancing self-esteem. A Randomized Controlled Trial (RCT) was used with a crossover design. Group 1 received six sessions EMDR first and then six sessions COMET; group 2 vice versa. Assessments were made at baseline (T0), end of first treatment (T1), and end of second treatment (T2). Main outcome was self-esteem. We included 47 patients and performed Linear Mixed Models. COMET showed more improvements in self-esteem than EMDR: effect-sizes 1.25 versus 0.46 post-treatment. Unexpectedly, when EMDR was given first, subsequent effects of COMET were significantly reduced in comparison to COMET as the first intervention. For EMDR, sequence made no difference. Reductions in anxiety and depression were mediated by better self-esteem. COMET was associated with significantly greater improvements in self-esteem than EMDR in patients with anxiety disorders. EMDR treatment reduced the effectiveness of subsequent COMET. Improved self-esteem mediated reductions in anxiety and depression symptoms. Copyright © 2016 Elsevier Ltd. All rights reserved.

Diabetes self-management education and home visits have been found to improve clinical outcomes in individuals living with diabetes. The purpose of this pilot project was to evaluate the feasibility and effectiveness of conducting self-management education in patients' homes. Baseline biometric data was collected from a cohort of adult patients with diabetes. Home visits to 19 patients were conducted by doctoral students from Rutgers University School of Nursing. The visits included knowledge assessment, review of foods in the home, diabetes self-management education, and teaching the proper use of monitoring tools such as the glucometer and blood pressure monitor. Biomarkers were obtained post-intervention and were compared to baseline biomarkers. Descriptive lifestyle data was collected and opportunities for customized patient education were provided. The biomarkers improved overall during the four months after the education intervention. The mean A1C reduced 12% (p=0.0107), the mean glucose reduced 12% (p=0.0994), the mean BMI reduced 2% (p=0.1490), the systolic pressure reduced 1% (p=0.4196), and the diastolic pressure remained stable. Specific goal setting further increased the improvement in the area the individual planned to address. This project supports prior studies that found that in-home educational programs can improve the self-management of diabetes and lead to improvement in health indicators. The benefits of the study included personal attention in ensuring the correct use of home health monitoring devices, building self-management confidence, and identifying treatment barriers that may not be easily discerned in a clinic setting.

Medium-term effectiveness of online behavioral training in migraine self-management: A randomized trial controlled over 10 months.

This randomized, controlled trial examined the medium-term effectiveness of online behavioral training in migraine self-management (oBT; N = 195) versus waitlist control (WLC; N = 173) on attack frequency, indicators of self-management (primary outcomes), headache top intensity, use of rescue medications, quality of life and disability (secondary outcomes). An online headache diary following the ICHD-II and questionnaires were completed at baseline (T0), post-training (T1) and six months later (T2). Missing data (T1: 24%; T2: 37%) were handled by multiple imputation. We established effect sizes (ES) and tested between-group differences over time with linear mixed modelling techniques based on the intention-to-treat principle. At T2, attack frequency had improved significantly in oBT (-23%, ES = 0.66) but also in WLC (-19%; ES = 0.52). Self-efficacy, internal and external control in migraine management--and triptan use--improved only in oBT, however. This indicates different processes in both groups and could signify (the start of) active self-management in oBT. Also, only oBT improved migraine-specific quality of life to a sizable extent. oBT produced self-management gains but could not account for improved attack frequency, because WLC improved as well. The perspective that BT effects develop gradually, and that online delivery will boost BT outreach, justifies further research. © International Headache Society 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

2017-07-01

The purpose of this study was to assess the impact of an anti-gravity treadmill return to running programme on self-efficacy and subjective knee function following knee osteochondral surgery. A 39-year-old otherwise healthy female endurance runner with a left knee femoral cartilage grade 3-4 defect 3 cm 2 . The patient underwent single step arthroscopic microfracture with Bone Marrow Aspirate Concentrate. An AlterG ® anti-gravity treadmill was used to manipulate loading during a graduated phased return to running over 8 weeks. Self-efficacy was evaluated using the Self-Efficacy for Rehabilitation outcomes scale (SER) and the Knee Self-Efficacy Scale (K-SES). Subjective knee function was evaluated using the Knee injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentation Committee Subjective Knee Form (IKDC). The programme resulted in improvements in SER (57%), K-SES present (89%) and K-SES future (65%) self-efficacy domains. The IKDC score demonstrated a clinically important improvement with an increase from 62.1 in week 1-86.2 in week 8 (39%). Only the KOOS Sport/Rec subscale showed a clinically important improvement from week 1 to week 8. The programme resulted in improved knee and rehabilitation self-efficacy and subjective knee function following osteochondral repair of the knee. This case report illustrates the importance of considering self-efficacy in rehabilitation after knee osteochondral surgery and highlights the potential role for anti-gravity treadmills in enhancing self-efficacy and subjective knee function in preparation for a return to sport.

Hermida, Jorge; Broughton, Edward I; Miller Franco, Lynne

2011-12-01

Health care quality improvement (QI) efforts commonly use self-assessment to measure compliance with quality standards. This study investigates the validity of self-assessment of quality indicators. Cross sectional. A maternal and newborn care improvement collaborative intervention conducted in health facilities in Ecuador in 2005. Four external evaluators were trained in abstracting medical records to calculate six indicators reflecting compliance with treatment standards. About 30 medical records per month were examined at 12 participating health facilities for a total of 1875 records. The same records had already been reviewed by QI teams at these facilities (self-assessment). Overall compliance, agreement (using the Kappa statistic), sensitivity and specificity were analyzed. We also examined patterns of disagreement and the effect of facility characteristics on levels of agreement. External evaluators reported compliance of 69-90%, while self-assessors reported 71-92%, with raw agreement of 71-95% and Kappa statistics ranging from fair to almost perfect agreement. Considering external evaluators as the gold standard, sensitivity of self-assessment ranged from 90 to 99% and specificity from 48 to 86%. Simpler indicators had fewer disagreements. When disagreements occurred between self-assessment and external valuators, the former tended to report more positive findings in five of six indicators, but this tendency was not of a magnitude to change program actions. Team leadership, understanding of the tools and facility size had no overall impact on the level of agreement. When compared with external evaluation (gold standard), self-assessment was found to be sufficiently valid for tracking QI team performance. Sensitivity was generally higher than specificity. Simplifying indicators may improve validity.

A randomized trial compared the time course and differential predictors of symptom improvement in 2 treatments for depression. Forty-nine adults (84% female) who were not taking antidepressant medications and met diagnostic criteria for major depressive disorder or dysthymia were randomly assigned either to cognitive-behavioral therapy (CBT) or self-system therapy (SST), a treatment that targets problems in self-regulation, the ongoing process of evaluating progress toward personal goals. Self-regulatory variables (promotion and prevention focus and goal disengagement and reengagement) were assessed as potential moderators of efficacy. At intake, most participants reported depression in the moderate to severe range and had histories of recurrent episodes and previous treatment attempts. Self-reported symptoms of depression and anxiety were assessed at each therapy session. Multilevel modeling was used to examine (a) differences in change associated with the treatment conditions and (b) moderation of treatment efficacy by pretreatment measures of self-regulatory deficits. Both treatments were effective and did not show differences in the magnitude or rate of symptom change or in dropout rates, suggesting that CBT and SST were equally effective in improving depression and anxiety. Patients with self-regulatory deficits, however, showed greater improvement in depressive symptoms with SST. Specifically, patients with low promotion focus and low goal reengagement responded better to SST, whereas patients with high prevention focus responded better to CBT. Overall, the results corroborate previous research suggesting that SST is a viable short-term treatment for depression that is particularly effective in helping patients compensate for self-regulatory deficits.

To explore the need for self-monitoring and self-care education in heart failure patients with diabetes (HF- DM patients) by describing cognitive and affective factors to provide guidance in developing effective self-management education. A cross-sectional correlation design was employed using baseline patient data from a study testing a 12-week patient and family dyad intervention to improve dietary and medication-taking self-management behaviors in HF patients. Data from 116 participants recruited from metropolitan Atlanta area were used. Demographic and comorbidities, physical function, psychological distress, relationship with health care provider, self-efficacy (medication taking and low sodium diet), and behavioral outcomes (medications, dietary habits) were assessed. Descriptive statistics and a series of chi-square tests, t tests, or Mann-Whitney tests were performed to compare HF patients with and without DM. HF-DM patients were older and heavier, had more comorbidities, and took more daily medications than HF patients. High self-efficacy on medication and low-sodium diet was reported in both groups with no significant difference. Although HF-DM patients took more daily medications than HF, both groups exhibited high HF medication-taking behaviors. The HF-DM patients consumed significantly lower total sugar than HF patients but clinically higher levels of sodium. Diabetes educators need to be aware of potential conflicts of treatment regimens to manage 2 chronic diseases. Special and integrated diabetes self-management education programs that incorporate principles of HF self-management should be developed to improve self-management behavior in HF-DM patients.

2015-04-01

The aim of the current study was to describe participants' experiences and examine the effects of group therapy on self-esteem and state anger among the adolescent children of immigrants in the US. A quasi-experimental design and qualitative and quantitative methods were used. Group therapy was conducted for 8weeks. Thirty-three adolescents took part in the study. Quantitative results revealed that group therapy improved self-esteem (t=2.222. p<.05) but not state anger. However, qualitative results suggested that group therapy helped improve interpersonal relationships and communication skills, the forgiveness of others, and the management of anger. Furthermore, group therapy utilizing positive psychology strategies improved self-esteem, interpersonal relationships, and communication skills. Copyright © 2014 Elsevier Inc. All rights reserved.

2015-11-01

Giving birth and adjusting to a new baby can be difficult and stressful for new mothers. Negative mood may occur during this time and can affect women, their parenting and the infant's development. This pilot study evaluated a brief online self-help intervention designed to promote positive mood in mothers of babies and toddlers. Women in the UK who had given birth within the previous 18 months were randomly allocated to the online self-help intervention (n = 40) or active comparison group exercise (n = 40) which was matched for time and structure. Mood was measured before and after the intervention. Acceptability was examined at the end of the trial. The self-help intervention was acceptable to the majority of women and significantly increased positive mood compared to the comparison condition. This effect persisted after controlling for self-esteem, anxiety and depression. These results suggest that a simple self-help intervention focused on changing beliefs about oneself as a mother can have an immediate impact on women's mood. Further research is need to see whether these improvements continue long-term and what processes underlie these improvements.

Patient education is a key component in the management of chronic obstructive pulmonary disease (COPD). Delivering effective education to ethnic groups with COPD is a challenge. The objective of this study was to develop and assess the effectiveness of culturally and linguistically specific audiovisual educational materials in supporting self-management practices in Mandarin- and Cantonese-speaking patients. Educational materials were developed using participatory approach (patients involved in the development and pilot test of educational materials), followed by a randomized controlled trial that assigned 91 patients to three intervention groups with audiovisual educational interventions and one control group (pamphlet). The patients were recruited from outpatient clinics. The primary outcomes were improved inhaler technique and perceived self-efficacy to manage COPD. The secondary outcome was improved patient understanding of pulmonary rehabilitation procedures. Subjects in all three intervention groups, compared with control subjects, demonstrated postintervention improvements in inhaler technique (P<0.001), preparedness to manage a COPD exacerbation (P<0.01), ability to achieve goals in managing COPD (P<0.01), and understanding pulmonary rehabilitation procedures (P<0.05). Culturally appropriate educational interventions designed specifically to meet the needs of Mandarin and Cantonese COPD patients are associated with significantly better understanding of self-management practices. Self-management education led to improved proper use of medications, ability to manage COPD exacerbations, and ability to achieve goals in managing COPD. A relatively simple culturally appropriate disease management education intervention improved inhaler techniques and self-management practices. Further research is needed to assess the effectiveness of self-management education on behavioral change and patient empowerment strategies.

To evaluate the self-esteem and quality of life in adolescents with extreme obesity before and one year after laparoscopic sleeve gastrectomy as obesity is a major challenging medical problem, not only in adults but also in children and adolescents in Saudi Arabia. In a prospective cohort study, 32 adolescents (aged 13-17 years) with extreme obesity (Group 1) presenting for laparoscopic sleeve gastrectomy (LSG) were compared with 32 matched, healthy, nonobese adolescents (aged 14-17 years) (Group 2) with regards to self-esteem and quality of life. Assessment was done using the Rosenberg Self-Esteem Scale and Pediatric Quality of Life Inventory version 4.0 (self- and parent report), respectively. Body mass index (BMI) Z scores were calculated for both groups. We found significantly poor self-esteem and impairment in all domains of quality of life (self- and parent report) in Group 1 compared with Group 2 (P<.001). Self esteem and quality of life (self- and parent reports) significantly improved 1 year after LSG (P<.001), and the weight loss induced by LSG, reflected by a decrease in BMI Z scores, was a significant predictor for the improvement in self-esteem (R2=0.28 and P=.003) and quality of life (R(2)=0.67 and P<.001). LSG was found to be a safe and effective operation in adolescents with extreme obesity: LSG leads to weight loss, with subsequent improvement in self-esteem and quality of life.

Predicting Treatment Outcomes from Prefrontal Cortex Activation for Self-Harming Patients with Borderline Personality Disorder: A Preliminary Study

PubMed Central

Ruocco, Anthony C.; Rodrigo, Achala H.; McMain, Shelley F.; Page-Gould, Elizabeth; Ayaz, Hasan; Links, Paul S.

2016-01-01

Self-harm is a potentially lethal symptom of borderline personality disorder (BPD) that often improves with dialectical behavior therapy (DBT). While DBT is effective for reducing self-harm in many patients with BPD, a small but significant number of patients either does not improve in treatment or ends treatment prematurely. Accordingly, it is crucial to identify factors that may prospectively predict which patients are most likely to benefit from and remain in treatment. In the present preliminary study, 29 actively self-harming patients with BPD completed brain-imaging procedures probing activation of the prefrontal cortex (PFC) during impulse control prior to beginning DBT and after 7 months of treatment. Patients that reduced their frequency of self-harm the most over treatment displayed lower levels of neural activation in the bilateral dorsolateral prefrontal cortex (DLPFC) prior to beginning treatment, and they showed the greatest increases in activity within this region after 7 months of treatment. Prior to starting DBT, treatment non-completers demonstrated greater activation than treatment-completers in the medial PFC and right inferior frontal gyrus. Reductions in self-harm over the treatment period were associated with increases in activity in right DLPFC even after accounting for improvements in depression, mania, and BPD symptom severity. These findings suggest that pre-treatment patterns of activation in the PFC underlying impulse control may be prospectively associated with improvements in self-harm and treatment attrition for patients with BPD treated with DBT.

To explore how older people maintained and improved their self-efficacy in managing home rehabilitation and their adherence to rehabilitation exercise programmes following orthopaedic surgery. Successful postoperative orthopaedic rehabilitation for older people depends on building their confidence about adherence to exercise programmes designed to improve their functional performance. Many older people, however, do not reach a satisfactory level of functional ability before discharge and some fail to adhere to their rehabilitation exercise programme at home. This contributes to a reduced quality of life. Although many studies report the influences of self-efficacy, little is known about the factors that help rebuild self-efficacy beliefs towards postdischarge exercise following orthopaedic surgery. A descriptive exploratory qualitative study. Semi-structured interviews were used with 15 older people who had returned to their homes following orthopaedic surgery. Findings emphasise the importance of social support from family, friends and community to nurture self-efficacy. Accessing personal beliefs and attitudes, adaptive strategies and goal setting were all sources and ways participants rebuilt their confidence and motivation in regard to adhering to a rehabilitation programme. Facilitating self-efficacy assists older people to manage home rehabilitation and planning care with family and friends to create a support system in early discharge planning allows a safer and smoother recovery. Rehabilitation programmes and education should encourage an understanding of self-efficacy as a means to improve individual functional performance. © 2012 Blackwell Publishing Ltd.

Implementation of a Food-Based Science Curriculum Improves Fourth-Grade Educators' Self-efficacy for Teaching Nutrition

Background Teacher self-efficacy can positively impact student dietary behaviors; however, limited curricular resources and professional development can serve as barriers to the provision of nutrition education in the classroom. The purpose of this study was to assess the impact of a food-based, integrative science curriculum on 4th grade teachers’ self-efficacy toward teaching nutrition. Methods Researchers used a quasi-experimental design to implement the FoodMASTER Intermediate (FMI) curriculum in 19 4th-grade classrooms across Ohio and North Carolina. The Nutrition Teaching Self-Efficacy Scale was used to assess baseline and post-test teacher self-efficacy using a 4-point Likert-scale (1=not confident at all; 4=very confident). ANCOVA and Wilcoxon-Signed Rank Test were used for statistical analysis. Results Teachers in the intervention group displayed significantly higher post-efficacy expectation scores (mean=3.52; sd=0.41) than comparison group teachers (mean=2.86; sd=0.55). Overall, the intervention group showed significant improvement in self-efficacy on 15 of the 18 items. Discussion The results suggest providing training and integrative resources to teachers can significantly improve self-efficacy toward teaching nutrition. Future research should focus on determining the amount of training needed to improve the quality of teacher-delivered nutrition education. Translation to Health Education Practice Health educators can use the findings to inform the development of teacher trainings in nutrition and health. PMID:28392881

Self-harm is a potentially lethal symptom of borderline personality disorder (BPD) that often improves with dialectical behavior therapy (DBT). While DBT is effective for reducing self-harm in many patients with BPD, a small but significant number of patients either does not improve in treatment or ends treatment prematurely. Accordingly, it is crucial to identify factors that may prospectively predict which patients are most likely to benefit from and remain in treatment. In the present preliminary study, 29 actively self-harming patients with BPD completed brain-imaging procedures probing activation of the prefrontal cortex (PFC) during impulse control prior to beginning DBT and after 7 months of treatment. Patients that reduced their frequency of self-harm the most over treatment displayed lower levels of neural activation in the bilateral dorsolateral prefrontal cortex (DLPFC) prior to beginning treatment, and they showed the greatest increases in activity within this region after 7 months of treatment. Prior to starting DBT, treatment non-completers demonstrated greater activation than treatment-completers in the medial PFC and right inferior frontal gyrus. Reductions in self-harm over the treatment period were associated with increases in activity in right DLPFC even after accounting for improvements in depression, mania, and BPD symptom severity. These findings suggest that pre-treatment patterns of activation in the PFC underlying impulse control may be prospectively associated with improvements in self-harm and treatment attrition for patients with BPD treated with DBT.

Significant resources are expended on quality improvement (QI) training courses. The authors sought to determine whether education provided in QI course training improves self-assessed QI content competence and QI-related productivity among course graduates. "Quality Improvement Essentials" is a four-month didactic and experiential course designed to prepare multidisciplinary professionals to participate in and lead QI efforts at Nationwide Children's Hospital (NCH). This study used a milestone-based self-assessment survey of graduates from 2012 to 2014 to gauge change in participants' self-assessed QI competency after course completion. Four competency domains were evaluated: QI knowledge; testing and implementing change using teams; data management and analysis; and spreading and sustaining science. Metrics for assessing individual QI productivity were presentation or publication of QI work outside NCH; local, regional, or national QI teaching; serving on a local, regional, or national QI committee; appointment as a QI leader; involvement in an internal or external QI collaborative; and leading a maintenance of certification Part IV project approved by NCH. Course participation more than doubled participants' self-assessed QI competence across all four domains. Gains continued after the course, increasing with time rather than degrading. Self-assessed competency increase was significantly associated with increased QI productivity. Self-assessed QI competence dramatically improved after participation in an educational course and continued to increase over time. Increased self-assessed QI competency correlated with increased individual QI productivity. Further studies are necessary to fully evaluate "return on investment" for this type of course.

We assessed the effectiveness of a brief structured diabetes education programme based on the concept of self-efficacy on self-care and glycaemic control using single-blind study design. One hundred and sixty-four participants with poorly controlled diabetes from two settings were randomized using computer-generated list into control (n = 82) and intervention (n = 82) groups, of which 151 completed the study. Monthly interventions over 12 weeks addressed the self-care practices of diet, physical activity, medication adherence and self-monitoring of blood glucose (SMBG). These self-care practices were assessed at Weeks 0 and 12 using pre- and post-questionnaires in both groups together with glycated haemoglobin A1c (HbA1c) and diabetes knowledge. In the intention-to-treat analysis (n = 164), the intervention group improved their SMBG (P = <0.001), physical activity (P = 0.001), HbA1c (P = 0.03), diabetes knowledge (P = <0.001) and medication adherence. At Week 12, HbA1c difference adjusted for SMBG frequency, medication adherence and weight change remained significant (P = 0.03) compared with control group. For within group comparisons, diabetes knowledge (P = <0.001), HbA1c level (P = <0.001), SMBG (P = <0.001) and medication adherence (P = 0.008) improved from baseline in the intervention group. In the control group, only diabetes knowledge improved (P = <0.001). These findings can contribute to the development of self-management diabetes education in Malaysia.

To understand why individuals with Parkinson's disease (PD) participate in a community-based therapeutic dance program and to explore its influence on perceived physical, social and emotional well-being of participants. A qualitative descriptive design was employed using one-on-one semi-structured interviews. Individuals with PD who participated in the Dancing with Parkinson's program were recruited from two locations. Interviews were audio-recorded, transcribed, de-identified and then placed into NVivo 10 software for analysis. A content analysis approach was used with an inductive analysis method to generate a coding scheme. Group discussion facilitated development of overarching themes. Ten participants' responses revealed that the dance program allows for self-improvement and regaining identity through disease self-management. Positive influences of socialization arose through the class, decreasing isolation and improving quality of life. Participants communicate through music and dance to enhance connection with others. Dancing with Parkinson's classes allow for re-development of the social self, which can increase sense of enjoyment in life. Dance programs provide opportunities for social interaction, non-verbal communication and self-improvement, reestablishing self-identity and a sense of usefulness. This study provides unique insight into the experience of participating in a dance program from the perspective of individuals with PD. Implications for rehabilitation Dance is emerging as a strategy to address the physical and psychosocial effects of Parkinson's disease (PD), but little is known regarding participants' perceptions of community-based therapeutic dance programs for PD. This study found that Dancing with Parkinson's (DWP) facilitated an improvement in social participation, resulting in decreased isolation and improved quality of life. Participation in the DWP program can facilitate a positive change in perspective and attitude toward a PD diagnosis, thereby increasing feelings of self-efficacy and improving self-management of the disease. Participants of this study emphasized the multifaceted benefits of DWP, suggesting that it has great potential for addressing not only the physical challenges, but also the cognitive and emotional challenges associated with PD.

Achieving competence in 'practice-based learning' implies that doctors can accurately self- assess their clinical skills to identify behaviours that need improvement. This study examines the impact of receiving feedback via performance benchmarks on medical students' self-assessment after a clinical performance examination (CPX). The authors developed a practice-based learning exercise at 3 institutions following a required 8-station CPX for medical students at the end of Year 3. Standardised patients (SPs) scored students after each station using checklists developed by experts. Students assessed their own performance immediately after the CPX (Phase 1). One month later, students watched their videotaped performance and reassessed (Phase 2). Some students received performance benchmarks (their scores, plus normative class data) before the video review. Pearson's correlations between self-ratings and SP ratings were calculated for overall performance and specific skill areas (history taking, physical examination, doctor-patient communication) for Phase 1 and Phase 2. The 2 correlations were then compared for each student group (i.e. those who received and those who did not receive feedback). A total of 280 students completed both study phases. Mean CPX scores ranged from 51% to 71% of items correct overall and for each skill area. Phase 1 self-assessment correlated weakly with SP ratings of student performance (r = 0.01-0.16). Without feedback, Phase 2 correlations remained weak (r = 0.13-0.18; n = 109). With feedback, Phase 2 correlations improved significantly (r = 0.26-0.47; n = 171). Low-performing students showed the greatest improvement after receiving feedback. The accuracy of student self-assessment was poor after a CPX, but improved significantly with performance feedback (scores and benchmarks). Videotape review alone (without feedback) did not improve self-assessment accuracy. Practice-based learning exercises that incorporate feedback to medical students hold promise to improve self-assessment skills.

To conduct a systematic review and meta-analysis of randomized controlled trials assessing the effectiveness of serious games in improving knowledge and/or self-management behaviors in young people with chronic conditions. The authors searched the databases PubMed, Cochrane Library, Web of Sciences, and PsychINFO for articles published between January 1990 and January 2014. Reference lists were hand-searched to retrieve additional studies. Randomized controlled trials that compared a digital game with either standard education or no specific education in a population of children and/or adolescents with chronic conditions were included. The authors identified 9 studies in which the effectiveness of serious games in young people with chronic conditions was evaluated using a randomized controlled trials design. Six studies found a significant improvement of knowledge in the game group from pretest to posttest; 4 studies showed significantly better knowledge in the game group than in the control group after the intervention. Two studies reported significantly better self-management in the game group than in the control group after the intervention. Seven studies were included in the meta-analysis. For knowledge, pooled estimate of Hedges' gu was 0.361 (95% confidence intervals, 0.098-0.624), demonstrating that serious games improve knowledge in patients. For self-management, pooled estimate of Hedges' gu was 0.310 (95% confidence intervals, 0.122-0.497), showing that gaming improves self-management behaviors. The authors' meta-analysis shows that educational video games can be effective in improving knowledge and self-management in young people with chronic conditions. © The Author 2015.

  One of the major concerns after an acute lateral ankle sprain is the potential for development of chronic ankle instability (CAI). The existing research has determined that clinician-delivered plantar massage improves postural control in those with CAI. However, the effectiveness of self-administered treatments and the underlying cause of any improvements remain unclear.   To determine (1) the effectiveness of a self-administered plantar-massage treatment in those with CAI and (2) whether the postural-control improvements were due to the stimulation of the plantar cutaneous receptors.   Crossover study.   University setting.   A total of 20 physically active individuals (6 men and 14 women) with self-reported CAI.   All participants completed 3 test sessions involving 3 treatments: a clinician-delivered manual plantar massage, a patient-delivered self-massage with a ball, and a clinician-delivered sensory brush massage.   Postural control was assessed using single-legged balance with eyes open and the Star Excursion Balance Test.   Static postural control improved (P ≤ .014) after each of the interventions. However, no changes in dynamic postural control after any of the interventions were observed (P > .05). No differences were observed between a clinician-delivered manual plantar massage and either a patient-delivered self-massage with a ball or a clinician-delivered sensory brush massage in any postural-control outcome.   In those with CAI, single 5-minute sessions of traditional plantar massage, self-administered massage, and sensory brush massage each resulted in comparable static postural-control improvements. The results also provide empirical evidence suggesting that the mechanism for the postural-control improvements is the stimulation of the plantar cutaneous receptors.

BACKGROUND Men with erectile dysfunction (ED) often have low self-esteem, confidence, and sexual relationship satisfaction. OBJECTIVE We evaluated the impact of sildenafil citrate and its generalizability across cultures on self-esteem, confidence, and sexual relationship satisfaction in men with ED using the Self-Esteem And Relationship (SEAR) questionnaire. DESIGN Pooled analysis of 2 double-blind, placebo-controlled, flexible-dose trials of sildenafil with identical protocols: 1 was conducted in the United States and the other in Mexico, Brazil, Australia, and Japan. PATIENTS Men ≥18 years old with ED. MEASUREMENTS The impact of treatment on psychosocial factors associated with ED was determined by patient responses to the SEAR questionnaire. Erectile function was determined using the International Index of Erectile Function (IIEF) and a global efficacy question. Successful sexual intercourse attempts were derived from event logs of sexual activity. Treatment effect sizes were calculated for all study outcomes. RESULTS Compared with patients who received placebo (n = 274), patients who received sildenafil (n = 279) reported significantly greater improvements (P<.0001) in self-esteem, confidence, sexual relationship satisfaction, and in all sexual function domains of the IIEF. Treatment effect sizes were large (range, 0.7 to 1.2) for all SEAR components, and improvement in psychosocial measures showed moderate to high correlations (range, 0.50 to 0.83, P<.0001) with improvement in erectile function, percentage of successful intercourse attempts, and global efficacy. CONCLUSIONS In men with ED from 5 different nations, sildenafil produced substantial improvements in self-esteem, confidence, and sexual relationship satisfaction. Improvements in these psychosocial factors were observed crossculturally and correlated significantly and tangibly with improvements in erectile function. PMID:16836626

We hypothesized that people with type 2 diabetes in an online diabetes self-management program, compared with usual-care control subjects, would 1) demonstrate reduced A1C at 6 and 18 months, 2) have fewer symptoms, 3) demonstrate increased exercise, and 4) have improved self-efficacy and patient activation. In addition, participants randomized to listserve reinforcement would have better 18-month outcomes than participants receiving no reinforcement. A total of 761 participants were randomized to 1) the program, 2) the program with e-mail reinforcement, or 3) were usual-care control subjects (no treatment). This sample included 110 American Indians/Alaska Natives (AI/ANs). Analyses of covariance models were used at the 6- and 18-month follow-up to compare groups. At 6 months, A1C, patient activation, and self-efficacy were improved for program participants compared with usual care control subjects (P < 0.05). There were no changes in other health or behavioral indicators. The AI/AN program participants demonstrated improvements in health distress and activity limitation compared with usual-care control subjects. The subgroup with initial A1C >7% demonstrated stronger improvement in A1C (P = 0.01). At 18 months, self-efficacy and patient activation were improved for program participants. A1C was not measured. Reinforcement showed no improvement. An online diabetes self-management program is acceptable for people with type 2 diabetes. Although the results were mixed they suggest 1) that the program may have beneficial effects in reducing A1C, 2) AI/AN populations can be engaged in and benefit from online interventions, and 3) our follow-up reinforcement appeared to have no value.

Behavioral Recommendations in Health Research News as Cues to Action: Self-Relevancy and Self-Efficacy Processes.

PubMed

Chang, Chingching

2016-08-01

This study argues that behavioral recommendations in health news function as cues to action. A proposed self-oriented model seeks to explore the impacts of behavioral recommendations in health research news as cues to action through their influences on self-relevancy and self-efficacy. A content analysis (Study 1) first establishes that health research news commonly features behavioral recommendations. A message experiment (Study 2) then explores the utility of behavioral recommendations as cues to action by demonstrating a self-relevancy effect: Health research news with, as opposed to without, behavioral recommendations increases the self-relevancy of advocated health behaviors, which then improve people's attitudes toward and intentions to adopt those behaviors. A second message experiment (Study 3) tests whether varying presentations of behavioral recommendations alter their effectiveness as cues to action and thus people's behavioral intentions through a dual effect process. In addition to the previously demonstrated self-relevancy effect, this experiment shows that concrete, as opposed to abstract, behavioral recommendations trigger a self-efficacy effect, increasing perceived self-efficacy and further improving behavioral intentions.

Gastroesophageal reflux disease is a chronic disease with a high incidence worldwide. The various symptoms have substantial impact on the quality of life of affected individuals. A long-term self-management program can increase the ability of patients to make behavioral changes, and health outcomes can improve as a consequence. This study's aim was to evaluate the effectiveness of a self-management program for gastroesophageal reflux disease. A total of 115 patients with gastroesophageal reflux disease were allocated to the experimental group and the control group. The former received self-management intervention along with conventional drug therapy, whereas the latter received standard outpatient care and conventional drug therapy. After the clinical trial, the control group also received the same self-management intervention. The levels of self-management behaviors, self-efficacy, gastroesophageal reflux disease symptoms, and psychological condition were compared. Those in the experimental group demonstrated significantly higher self-efficacy for managing their illness, showed positive changes in self-management behaviors, and had comparatively better remission of symptoms and improvement in psychological distress. The program helped patients with gastroesophageal reflux disease self-manage their illness as possible.

The purpose of this pilot study was to test the impact of language-free, low literacy self-care management patient education materials in an ethnically diverse multilingual heart failure (HF) population. A one group pre-test-post-test design measured changes in self-care, knowledge and health-related quality of life (HRQL) after a 1 month intervention using language-free, low literacy self-care management patient education materials and delivered by a health educator. The ethnically diverse sample (n=21) was predominately male (72%), 48% Black, 42% Hispanic, and 28% marginal/inadequate literacy. There were significant improvements in self-care and knowledge but not HRQL. Language-free, low literacy self-care patient education may facilitate improved self-care and knowledge in diverse populations who are at risk for poor HF outcomes. Copyright © 2015 Elsevier Inc.

Thirty-one patients treated at the Faculty of Dentistry, University of Malaya, were assessed for their satisfaction following orthognathic surgery. The female to male ratio was 22:9 with an age range of 17 to 36. Almost all patients (97%) listed appearance as one of their rationales for surgery. More males (78%) than females (59%) wanted functional improvement, while more females (91%) than males (33%) hoped for improvement in self-confidence. All patients reported esthetic improvement while 68% each reported improvement in mastication and self-confidence. Slightly more than half (52%) chose esthetic improvement as the single most important factor resulting in satisfaction. Almost ninety percent of male patients claimed satisfaction with functional improvement, while 68% of those who found satisfaction in improved self-confidence were females. Eighty-seven percent rated their post-surgical changes as being well accepted by their family. The impact of these findings on the success of the surgery and the need to reinforce verbal communication with printed pamphlets are emphasized.

Low self-esteem has been identified as a maintaining factor in Cognitive Behavioural models of eating disorders and links have been identified between early memories, negative core beliefs and mental imagery. This study explored the impact of positive and negative self-imagery on aspects of the working self (implicit and explicit self-esteem, self-concept clarity and self-discrepancy) and affect. Participants with high levels of eating disorder cognitions completed measures of explicit self-esteem, self-concept clarity, self-discrepancy and affect prior to completing a positive or negative self-imagery retrieval task. Baseline measures were then repeated and a measure of implicit self-esteem completed. Positive self-imagery retrieval led to a significant increase in positive explicit self-esteem and a significant reduction in negative explicit self-esteem and actual-ideal self-discrepancies. Negative self-imagery retrieval led to a significant increase in negative explicit self-esteem and actual-ideal self-discrepancies and a significant reduction in positive explicit self-esteem. Levels of implicit self-esteem did not differ between the two groups post imagery manipulation. Retrieving a positive self-image also led to an improvement in state self-concept clarity; however, no effect was found for the negative self-imagery intervention. Holding a positive self-image in mind led to an increase in state positive affect and a reduction in state negative affect. The opposite was found for negative self-image retrieval. The study did not measure implicit self-esteem at baseline. Imagery techniques that involve the retrieval of a positive self-image may help to improve aspects of the working-self and affect in those with eating difficulties. Copyright © 2018 Elsevier Ltd.

Robotic C-arms are capable of complex orbits that can increase field of view, reduce artifacts, improve image quality, and/or reduce dose; however, it can be challenging to obtain accurate, reproducible geometric calibration required for image reconstruction for such complex orbits. This work presents a method for geometric calibration for an arbitrary source-detector orbit by registering 2D projection data to a previously acquired 3D image. It also yields a method by which calibration of simple circular orbits can be improved. The registration uses a normalized gradient information similarity metric and the covariance matrix adaptation-evolution strategy optimizer for robustness against local minima and changes in image content. The resulting transformation provides a ‘self-calibration’ of system geometry. The algorithm was tested in phantom studies using both a cone-beam CT (CBCT) test-bench and a robotic C-arm (Artis Zeego, Siemens Healthcare) for circular and non-circular orbits. Self-calibration performance was evaluated in terms of the full-width at half-maximum (FWHM) of the point spread function in CBCT reconstructions, the reprojection error (RPE) of steel ball bearings placed on each phantom, and the overall quality and presence of artifacts in CBCT images. In all cases, self-calibration improved the FWHM—e.g. on the CBCT bench, FWHM = 0.86 mm for conventional calibration compared to 0.65 mm for self-calibration (p < 0.001). Similar improvements were measured in RPE—e.g. on the robotic C-arm, RPE = 0.73 mm for conventional calibration compared to 0.55 mm for self-calibration (p < 0.001). Visible improvement was evident in CBCT reconstructions using self-calibration, particularly about high-contrast, high-frequency objects (e.g. temporal bone air cells and a surgical needle). The results indicate that self-calibration can improve even upon systems with presumably accurate geometric calibration and is applicable to situations where conventional calibration is not feasible, such as complex non-circular CBCT orbits and systems with irreproducible source-detector trajectory.

Poor adherence to treatment is common in hemodialysis patients. However, effective interventions for adherence in this population are lacking. Small studies of behavioral interventions have yielded improvements, but clinical effectiveness and long-term effects are unclear. Multicenter parallel (1:1) design, blinded cluster-randomized controlled trial. Patients undergoing maintenance hemodialysis enrolled in 14 dialysis centers. Dialysis shifts of eligible patients were randomly assigned to either an interactive and targeted self-management training program (HED-SMART; intervention; n=134) or usual care (control; n=101). HED-SMART, developed using the principles of problem solving and social learning theory, was delivered in a group format by health care professionals over 4 sessions. Serum potassium and phosphate concentrations, interdialytic weight gains (IDWGs), self-reported adherence, and self-management skills at 1 week, 3 months, and 9 months postintervention. 235 participants were enrolled in the study (response rate, 44.2%), and 82.1% completed the protocol. IDWG was significantly lowered across all 3 assessments relative to baseline (P<0.001) among patients randomly assigned to HED-SMART. In contrast, IDWG in controls showed no change except at 3 months, when it worsened significantly. Improvements in mineral markers were noted in the HED-SMART arm at 3 months (P<0.001) and in potassium concentrations (P<0.001) at 9 months. Phosphate concentrations improved in HED-SMART at 3 months (P=0.03), but these effects were not maintained at 9 months postintervention. Significant differences between the arms were found for the secondary outcomes of self-reported adherence, self-management skills, and self-efficacy at all time points. Low proportion of patients with diabetes. HED-SMART provides an effective and practical model for improving health in hemodialysis patients. The observed improvements in clinical markers and self-report adherence, if maintained at the longer follow-up, could significantly reduce end-stage renal disease-related complications. Given the feasibility of this kind of program, it has strong potential for supplementing usual care. Registered at ISRCTN with study number ISRCTN31434033.

To examine the effect of a hospital-based clinic intervention on glycaemic control self-efficacy and glycaemic control behaviour of Chinese patients with type 2 diabetes mellitus (DM). Self-efficacy expectations are related to self-management of diabetes and, in conjunction with environmental support, are better predictors of behaviour than are knowledge and skills. Enhancing self-efficacy in patients with DM has been shown to have a positive effect on behavioural change and positively influence long-term glycaemic control. A randomised controlled trial study consisting of two-group pretest-post-test. One hundred and fifty-seven patients with type 2 DM were randomly divided into two groups: (1) the experimental group (77 patients) receiving one-month hospital-based clinic intervention and (2) the control group (80 patients) receiving usual care. Data collection instruments used in this study were Diabetes Management Self-Efficacy Scale and Summary of Diabetes Self-Care Activities Measure. Outcomes were determined by changes in glycaemic control self-efficacy and glycaemic control behaviour of patients with type 2 DM. The findings revealed that the experimental group showed statistically significant improvement in glycaemic control self-efficacy and glycaemic control behaviour immediately and four months after the intervention (F = 26.888, df = 1, 155, p < 0.05 and F = 18.619, df = 1, 155, p < 0.05, respectively). One-month hospital-based clinic intervention could be useful in improving glycaemic control self-efficacy and glycaemic control behaviour. Nurses can learn and use the sources of self-efficacy to enhance patients' self-efficacy on their glycaemic control in clinical care. The health education is most important in nursing care and should be considered while organising the hospital-based clinic intervention.

The aim of the present study was to explore perceptions and strategies of health care providers regarding diabetes self-management support for patients with low health literacy (LHL), and to compare their self-management support with the needs of patients with LHL and type 2 diabetes. This study serves as a problem analysis for systematic intervention development to improve diabetes self-management among patients with LHL. This qualitative study used in-depth interviews with general practitioners (n = 4), nurse practitioners (n = 5), and patients with LHL (n = 31). The results of the interviews with health care providers guided the patient interviews. In addition, we observed 10 general practice consultations. Providers described patients with LHL as uninvolved and less motivated patients who do not understand self-management. Their main strategy to improve self-management was to provide standard information on a repeated basis. Patients with LHL seemed to have a different view of diabetes self-management than their providers. Most demonstrated a low awareness of what self-management involves, but did not express needing more information. They reported several practical barriers to self-management, although they seemed reluctant to use the information provided to overcome them. Providing and repeating information does not fit the needs of patients with LHL regarding diabetes self-management support. Health care providers do not seem to have the insight or the tools to systematically support diabetes self-management in this group. Systematic intervention development with a focus on skills-based approaches rather than cognition development may improve diabetes self-management support of patients with LHL. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

The effectiveness of self-management interventions has been demonstrated. However, the benefits of generic vs. disease-specific programs are unclear, and their efficacy within a practice setting has yet to be fully explored. To compare the outcomes of the diabetes-specific self-management program (Diabetes) and the generic chronic disease Self-management Program (Chronic Condition) and to explore whether program characteristics, evaluated using the Quality Self-Management Assessment Framework (Q-SAF), provide insight into the results of the outcome evaluation. A pragmatic pretest, post-test design with 12-week follow up was used to compare the 2 self-management interventions. Outcomes were quality of life, self-efficacy, loneliness, self-management skills, depression, and health behaviours. People with diabetes self-selected attendance at the Diabetes or Chronic Condition program offered as part of routine practice. Participants with diabetes in the 2 programs (Diabetes=200; Chronic Condition=90) differed significantly in almost all demographic and clinical characteristics. Both programs yielded positive outcomes. Controlling for baseline and demographic characteristics, random effects modelling showed an interaction between time and program for 1 outcome: self-efficacy (p=0.029). Participants in the Chronic Condition group experienced greater improvements over time than did those in the Diabetes group. The Q-SAF analysis showed differences in program content, delivery and workforce capacity. People with diabetes benefited from both programs, but participation in the generic program resulted in greater improvements in self-efficacy for participants who had self-selected that program. Both programs in routine care led to health-related improvements. The Q-SAF can be used to assess the quality of programs. Copyright © 2015 Canadian Diabetes Association. Published by Elsevier Inc.

The objectives of this work were to develop a means of sampling atmospheric dusts on the premises of an oil refinery for electron microscopic study to carry out preliminary morphological analyses and to compare these dusts with those collected at sites beyond the refinery limits. Carbon and collodion membranes were used as a support for collection of dust particles straight on transmission electron microscopy (TEM) grids. Micrographs of the dust particles were taken at magnifications from ×4,000 to ×80,000 with a Tesla BS500 transmission electron microscope. Four parameters were defined on the basis of the micrographs: surface area, Feret diameter, circumference, and shape coefficient. The micrographs and literature data were used to classify the atmospheric dusts into six groups: particles with an irregular shape and rounded edges; particles with an irregular shape and sharp edges; soot and its aggregates; spherical particles; singly occurring, ultrafine dust particles; and particles not allocated to any of the previous five groups. The types of dusts found in all the samples were similar, although differences did exist between the various morphological parameters. Dust particles with the largest Feret diameter were present in sample 3 (mean, 0.739 μm)-these were collected near the refinery's effluent treatment plant. The particles with the smallest diameter were found in the sample that had been intended to be a reference sample for the remaining results (mean, 0.326 μm). The dust particles collected in the refinery had larger mean Feret diameters, even 100% larger, than those collected beyond it. Particles with diameters from 0.1 to 0.2 μm made up the most numerous group in all the samples collected in the refinery.

Objective: We aimed at studying the hemodynamic response (HR) to Interictal Epileptic Discharges (IEDs) using patient-specific and prolonged simultaneous ElectroEncephaloGraphy (EEG) and functional Near InfraRed Spectroscopy (fNIRS) recordings. Methods: The epileptic generator was localized using Magnetoencephalography source imaging. fNIRS montage was tailored for each patient, using an algorithm to optimize the sensitivity to the epileptic generator. Optodes were glued using collodion to achieve prolonged acquisition with high quality signal. fNIRS data analysis was handled with no a priori constraint on HR time course, averaging fNIRS signals to similar IEDs. Cluster-permutation analysis was performed on 3D reconstructed fNIRS data to identify significant spatio-temporal HR clusters. Standard (GLM with fixed HRF) and cluster-permutation EEG-fMRI analyses were performed for comparison purposes. Results: fNIRS detected HR to IEDs for 8/9 patients. It mainly consisted oxy-hemoglobin increases (seven patients), followed by oxy-hemoglobin decreases (six patients). HR was lateralized in six patients and lasted from 8.5 to 30 s. Standard EEG-fMRI analysis detected an HR in 4/9 patients (4/9 without enough IEDs, 1/9 unreliable result). The cluster-permutation EEG-fMRI analysis restricted to the region investigated by fNIRS showed additional strong and non-canonical BOLD responses starting earlier than the IEDs and lasting up to 30 s. Conclusions: (i) EEG-fNIRS is suitable to detect the HR to IEDs and can outperform EEG-fMRI because of prolonged recordings and greater chance to detect IEDs; (ii) cluster-permutation analysis unveils additional HR features underestimated when imposing a canonical HR function (iii) the HR is often bilateral and lasts up to 30 s.

Lewis M. Rutherfurd and the First Photograph of Solar Granulation

A major astronomical controversy of the mid-19th century was discordant descriptions of the small scale structure of the solar surface. Visual observers contradicted each other by describing the surface as consisting of “corrugations”, “willow leaves”, “rice grains”, “cumuli”, “thatch”, “granules”, etc. Early photographs of the solar surface were not good enough to settle the controversy. The French astronomer Jules Janssen is credited with the first 1876 photographs that clearly showed what we now call solar granulation (1876, CRAS 82, 1363). Upon seeing these images, New Yorker Lewis M. Rutherfurd (1878, MNRAS 38, 410) praised the high quality of Janssen’s images but asserted that he had also photographed granulation as early as 1871 using collodion wet plates. He sent copies of his best photograph to the Royal Astronomical Society to support his assertion. Curious about his claim, Briggs and Harvey set up Rutherfurd’s 13-inch achromatic refractor on Kitt Peak and found that it easily showed well-resolved solar granulation, so his claim might well have been justified. But without his plates we could not confirm the claim. For 140 years the copies of Rutherfurd’s best solar photograph remained in the archives of the Royal Astronomical Society and were recently discovered by Prosser (RAS Photographs A3/001B and A3/002). By coincidence a few days later, Briggs found the original August 11, 1871 plate. Despite poor condition these photographs show solar granulation. There are at least two other possible early claimants (Reade; Vogel) but their plates are almost certainly lost. Rutherfurd was a master of astronomical instrumentation and photography. He was reticent about his work, letting results speak for themselves, so it is satisfying to find that he was justified in making his claim of priority.
