Perceived barriers and enablers to physical activity participation in people with Alopecia Areata: a constructivist grounded theory study.

BACKGROUND: Alopecia Areata (AA) is an autoimmune disease that is characterised by hair loss. Individuals diagnosed with it often describe feelings of trauma and social rejection due to cosmetic repercussions and are at high risk of experiencing psychological distress. Physical activity (PA) participation has been associated with better mental health outcomes in diverse populations. A preliminary study of individuals with AA indicated that severe hair loss is associated with symptomatic depression, anxiety and stress, which negatively impacted PA participation. While strategies to increase PA participation in the general population have been established, little is known about PA participation in people with AA. This study aimed to understand barriers and enablers to PA participation in people with AA to inform the development of evidence-based interventions. METHODS: The study used a grounded theory (GT) methodology, relying on an iterative and simultaneous process of data collection, coding, theory development, and data comparisons to explore the perceived barriers and enablers to PA. Data were collected through a focus group (8 participants [33.38 ± 10.81 years]) and individual telephone interviews (8 participants [33.89 ± 11.87 years]). The study was conducted in Melbourne, Australia. Interview data were recorded digitally, transcribed verbatim and analysed. Recruitment continued until theoretical saturation was achieved. RESULTS: The constructivist grounded theory method used has assisted to develop an explanatory model which is used to explain the themes for barriers and enablers to PA participation. The four phases in the explanatory model are as follows (1) onset of AA; (2) reaction towards the condition; (3) adjustment; and (4) acceptance. CONCLUSION: The findings highlighted perceived barriers and enablers to PA participation in people with AA. Future interventions could consider addressing these barriers specifically to maximise effectiveness and to improve mental health status based on the phases of the explanatory model.

The relationship between physical activity levels and symptoms of depression, anxiety and stress in individuals with alopecia Areata.

BACKGROUND: Alopecia Areata (AA) is an autoimmune condition that is characterised by non-scarring hair loss. Its aesthetic repercussions can lead to profound changes in psychological well-being. Although physical activity (PA) has been associated with better mental health outcomes in diverse populations, the association in individuals with AA has not been established. The aim of this study was to examine the associations between PA and mental health outcomes in individuals with AA to inform intervention strategies for this specific population. METHODS: A cross-sectional study was conducted among individuals who were diagnosed with AA. A total of 83 respondents aged (40.95 ± 13.24 years) completed a self-report questionnaire consisting of International Physical Activity Questionnaire-Short Form (IPAQ-SF) and the Depression and Anxiety Stress Scale (DASS-21). Three-way contingency Chi-square analyses were used to determine the associations between PA, mental health outcomes and participants with hair loss of more than 50% on the scalp. RESULTS: 81.9% of the participants did not meet PA guidelines. Participants with hair loss of more than 50% on the scalp, and who did not meet PA guidelines, were significantly more likely to experience symptoms of severe depression (p = .003), moderate anxiety (p = .04) and mild stress (p = .003) than those who met guidelines CONCLUSION: Findings suggest that increased PA participation in AA individuals with severe hair loss is associated with improved mental health status. Intervention efforts for this specific population should consider barriers and enablers to PA participation as they face challenges that differ from the general population.

Hospital based epidemiology of HIV-1 in Bangalore, India.

PIP: Of more than 1 million people screened in serosurveillance centers across India, more than 6000 have been found to be infected with HIV. Bombay, Madras, and Manipur are the 3 epicenters of pandemic viral spread. The majority of infected individuals in southern India are in Tamil Nadu and Maharashtra states. HIV-1serology was, however, added to the center in Karnataka state amid reports of rising HIV seroprevalence. St. John's Medical College Hospital is in Bangalore, a rapidly growing city of the state. An ongoing study began screening high-risk groups and blood donors for seroprevalence to HIV in March, 1989. This report presents findings based upon the first 3 years of the study. In all, sera from 26,236 voluntary blood donors and 1364 high-risk group patients were screened with ELISA. 26 seropositives were identified, 17 of which were from Bangalore city and its suburbs; the others were from semi-urban environments. Quite a few were unaware of HIV infection and its implications. Most seropositives were males aged 20-40 years thought to have contracted HIV from heterosexual intercourse, although one admitted to homosexuality. Further, many are frequent travellers due to the nature of their jobs. Of the blood donors, none was seropositive in 1989, 1 in 1990, and 15 in 1992; a similar trend was observed among the high-risk group patients. These findings point to the as-yet modest, but growing, entry of HIV into populations in and around Bangalore. Continuous serosurveillance and vigorous health education of the population are required to stem further HIV infection.^ieng

Age-specific sero-prevalence of amoebiasis and giardiasis in southern Indian infants and children.

The age-specific sero-prevalence of amoebiasis and giardiasis was estimated in 91 pediatric diarrhoea and in 70 non-diarrhoeal cases from Southern India. Anti-amoeba/giardia IgG assays on 20 children with inflammatory bowel disease from the UK yielded base-line levels in a non-endemic symptomatic population. IgG, IgM, and IgA levels were estimated to E. histolytica and G. lamblia using an ELISA. Concomittant faecal examinations were done for the Indian children. There was a significant correlation between acquisition of sero-positivity and age. A rise in the IgG response to both organisms was evident between 38 and 47 and 13-24 months, respectively, in diarrhoeal and non-diarrhoeal cases. An appreciable IgM response occurred predominantly in diarrhoea cases and at a younger age (less than 24 months). IgA responses were low. Anti-protozoal IgG levels in the UK children were negligible. There was no relationship between faecal excretion and sero-positivity. The study shows an age-related antibody response to E. histolytica and G. lamblia.

Non-specific reactions in enzyme linked immunosorbent assays for serum antibody to entamoeba histolytica and Giardia lamblia in non-endemic areas.

Serum samples from 20 Indian children with diarrhoea were compared with those from 20 children resident in the United Kingdom who had been diagnosed as having ulcerative colitis, or Crohn's disease, or indeterminate colitis using enzyme linked immunosorbent assays specific for Entamoeba histolytica and Giardia lamblia. More than 50% of the United Kingdom patients had high IgG responses in ELISAs for E histolytica and G lamblia. A confirmatory ELISA showed that the British sera reacted specifically to bovine serum proteins rather than to protozoal antigens. Prior incubation of sera with 5% bovine serum prohibited this reaction. Bovine serum is an integral part of the crude soluble antigen used in most ELISAs for E histolytica and G lamblia and needs to be replaced with purified antigen preparations. The British sera also reacted to other commonly used blocking agents such as bovine serum albumin, casein, and normal sheep serum. These reactions were attributed to uptake of dietary antigens or an enhanced immunological response to these antigens in patients with inflammatory bowel disease.

Cerebrospinal fluid C-reactive protein measurement--a bedside test in the rapid diagnosis of bacterial meningitis.

C-reactive protein (C-RP) determinations were performed by the Latex agglutination method on the cerebrospinal fluid (CSF) samples of 212 patients with clinical features suggestive of meningitis. Patients were grouped as follows Group I: bacterial meningitis and partially treated bacterial meningitis (n = 22). Group II: viral encephalitis (n = 11). Group III: tuberculous meningitis (n = 18). Group IV: (i) febrile convulsions (n = 87); (ii) epileptic seizures (n = 70); (iii) intracranial haemorrhage (n = 4). C-RP was a better indicator of bacterial meningitis (sensitivity 91 per cent) than the Gram's stain (sensitivity 46 per cent). C-RP was positive in 91 per cent of patients in Group I, none in Groups II and III and 0.6 per cent in Group IV. C-RP determination in CSF proved to be a useful indicator of bacterial meningitis and served to distinguish it from viral encephalitis, tuberculous meningitis, febrile convulsions and other central nervous system disorders.
