Has Treatment Seeking Behaviour Changed in People Living with Epilepsy? Experience of People Living with Epilepsy Attending Adult Neurology Clinics in Enugu.

BACKGROUND: Over the years efforts has been made through public health education to change the knowledge, attitude and practice of epilepsy and seizures among the populace in Nigeria. One surrogate method of reviewing the impact of these educational interventions includes changes in treatment-seeking behavior of People Living With Epilepsy and the reasons for their choices of treatment. METHODS: This was a cross-sectional descriptive study. Data were collected from People Living With Epilepsy attending the medical outpatient clinics in two tertiary hospitals in Enugu, Enugu State southeast Nigeria. RESULTS: A total 276 people living with epilepsy were recruited with a mean age of 30.1 years and a median age of 25 years. After the onset of epilepsy, 76(27.5%) and 70(25.4%) visited general hospitals and teaching hospitals respectively, while prayer houses and traditional healing centers were first visited by 54(19.6%) and 40(14.5%) respectively. As a second choice of care 9(3.3%) and 13(4.7%) visited prayer houses and traditional healing centers. Only 42(15.2%) selected their treatment center because they were confident of getting a cure however, this was highest for those that visited traditional healing centers 11(27.5%). The age of onset of epilepsy positively correlated with selecting orthodox treatment at the choice of care, while occupational status negatively correlated with selecting orthodox care at the same period. CONCLUSIONS: Health care seeking behaviors among PLWE in Southeast Nigeria might have changed over the years as more people living with epilepsy were more likely to select orthodox treatment compared to non-orthodox means of treatment.

CONTEXTE: Au fil des ans, des efforts ont été déployés par le biais de l'éducation en santé publique pour changer les connaissances, les attitudes et les pratiques concernant l'épilepsie et les crises d'épilepsie parmi la population au Nigeria. Une méthode indirecte pour examiner l'impact de ces interventions éducatives comprend les changements dans le comportement de recherche de traitement des personnes vivant avec l'épilepsie et les raisons de leurs choix de traitement. MÉTHODES: Il s'agit d'une étude descriptive transversale. Les données ont été collectées auprès de personnes vivant avec l'épilepsie fréquentant les cliniques de consultations externes médicales dans deux hôpitaux tertiaires à Enugu, dans l'État d'Enugu, au sud-est du Nigeria. RÉSULTATS: Au total, 276 personnes vivant avec l'épilepsie ont été recrutées, avec un âge moyen de 30,1 ans et un âge médian de 25 ans. Après le début de l'épilepsie, 76 (27,5 %) et 70 (25,4 %) ont consulté respectivement des hôpitaux généraux et des hôpitaux universitaires, tandis que les lieux de prière et les centres de guérison traditionnelle ont été les premiers consultés par respectivement 54 (19,6 %) et 40 (14,5 %). Comme deuxième choix de soins, 9 (3,3 %) et 13 (4,7 %) ont consulté des lieux de prière et des centres de guérison traditionnelle. Seuls 42 (15,2 %) ont choisi leur centre de traitement parce qu'ils étaient confiants d'obtenir une guérison, cependant, ce taux était le plus élevé pour ceux qui ont consulté les centres de guérison traditionnelle (11 soit 27,5 %). L'âge de début de l'épilepsie était positivement corrélé avec la sélection d'un traitement orthodoxe comme choix de soins, tandis que le statut professionnel était négativement corrélé avec la sélection de soins orthodoxes au même moment. CONCLUSIONS: Les comportements de recherche de soins parmi les personnes vivant avec l'épilepsie dans le sud-est du Nigeria ont peut-être changé au fil des ans, car davantage de personnes vivant avec l'épilepsie étaient plus susceptibles de choisir un traitement orthodoxe par rapport aux moyens de traitement non orthodoxes. MOTS-CLÉS: Épilepsie, Comportement de recherche de soins, Guérisseurs traditionnels, Lieux de prière, Médecine orthodoxe, sud-est du Nigeria.

Efficacy and safety of dolutegravir/lamivudine in virologically suppressed female participants: week 48 data from the pooled TANGO and SALSA studies.

OBJECTIVES: Women represent >50% of people with HIV globally but have historically been underrepresented in clinical trials. We evaluated the efficacy and safety of switching to dolutegravir/lamivudine (DTG/3TC) vs continuing their current antiretroviral regimen (CAR) by sex assigned at birth (female and male) in virologically suppressed adults with HIV-1 without prior virological failure in a pooled analysis of two randomized controlled trials. METHODS: This analysis included 48-week data from the phase 3 TANGO and SALSA studies. Primary and key secondary endpoints included proportions of participants with HIV-1 RNA ≥50 and <50 copies/mL at week 48, respectively. Safety was also assessed. RESULTS: Of 1234 participants, 250 (DTG/3TC, n = 133; CAR, n = 117) were female at birth. Week 48 proportions of participants with Snapshot HIV-1 RNA ≥50 copies/mL were similar regardless of sex at birth (DTG/3TC vs CAR: female, <1% [1/133] vs 2% [2/117]; male, <1% [1/482] vs <1% [3/502]). Proportions with HIV-1 RNA <50 copies/mL were high across sexes and treatment groups (DTG/3TC vs CAR: female, 91% [121/133] vs 89% [104/117]; male, 94% [455/482] vs 94% [471/502]). Immunological response with DTG/3TC was slightly higher in female participants. Incidences of adverse events leading to withdrawal and serious adverse events were low and comparable between treatment groups and across sexes. Weight gain was higher with DTG/3TC than with CAR among female participants aged ≥50 years (treatment difference 2.08 kg [95% confidence interval 0.40-3.75]). CONCLUSIONS: Results confirm the robustness of DTG/3TC as a switch option in virologically suppressed females with HIV-1, with outcomes similar to those in males.

Risk factors for some tropical diseases in an African country.

BACKGROUND: Often, non-clinical risk factors could affect the predisposition of an individual to diseases. Understanding these factors and their impacts helps in disease prevention and control. This study identified risk factors for malaria, yellow fever, typhoid, chickenpox, measles, hepatitis B, and urinary tract infection in a population in an African country. METHODS: Our study was an observational, correlational, and quantitative one that explored relationships among risk variables and disease prevalence - without modifying or controlling the variables. Data for this study was obtained through random sampling of a population of patients and physicians in the eastern/southern, western, and northern parts of Nigeria in 2015-2016. A total of 2199 patient consultation forms were returned by 102 (out of 125) physicians, and considered useful for analysis. Demographic data of patients, physicians, and diagnosis outcomes were analysed descriptively through frequency distributions, aggregate analysis, and graphs. The influence of risk factors on the disease manifestations (diagnosis outcomes) was determined using regression analysis. RESULTS: Our results show that living in a tropical climate is by far a major risk factor associated with tropical diseases (malaria: t = 19.9, typhoid: t = - 3.2, chickenpox: t = - 6.5 and typhoid: t = 12.7). The risk for contracting infections is relative to specific diseases; for example, contact with chickenpox infected person poses a high risk of contracting the virus (t = 41.8), while poor personal hygiene predisposes people to high risk of urinary tract infection (t = 23.6). On the other hand, urbanization and homelessness pose very low risks of disposing the individual to the diseases under consideration, while low fluid intake, lack of voiding, and wearing non-cotton underwear predispose individuals to few diseases. CONCLUSION: The risk factors identified in our study exert differential and discriminating influences in the causation, predisposition, and transmission of these disease studied. It is recommended that significant effort be devoted by governments in the tropics to the mitigation of these modifiable risk factors. The most important strategy to mitigate the occurrence of these risk factors will be improving the living conditions of people and the provision of social protection measures to reduce the occurrence and burden of these diseases.

Examining the associations between self-care practices and psychological distress among nursing students during the COVID-19 pandemic.

There is limited research regarding the impact of self-care practices on psychological distress, specifically on nursing students during a pandemic, such as COVID-19 (Corona Virus Disease- 2019). A 10-minute electronic survey was sent to nursing students at a large academic-medical center, and data from 285 student respondents were analyzed to assess psychological status, attitudes and behaviors in regards to the COVID-19 pandemic. Significant differences were found when comparing self-care practice scores by school grade for total scores (F = 4.48 [df = 4,250], p = .002), emotional subscale (F = 4.78 [df = 4,250], p = .001), and relationship subscale (F = 3.44 [df = 4,250], p = .009). While there were no significant differences in psychological distress by school grade, graduate students had the lowest self-care practice score compared to all the other grades. Finally, the subscale and total self-care practice scores were significantly and negatively associated with psychological distress. These findings suggest that utilization of self-care practices is associated with lower psychological distress, and should therefore be promoted among nursing student populations and integrated into curricula. Future studies should assess specific needs geared towards populations that may have poor self-care practices, such as graduate students, and understand ways to improve sleep quality to mitigate rates of psychological distress during a pandemic.

Does preoperative chemical depilation make any difference in postoperative wound infection?

BACKGROUND: Preparation for surgery has traditionally included the removal of body hair from the intended surgical wound site. The effect of this practice on postoperative wound infection is yet to be fully elucidated. AIMS: This study sought to determine if preoperative chemical depilation reduces the risk of surgical site infection (SSI). METHODOLOGY: Two methods of preoperative hair removal: razor shaving and depilatory cream were compared. The eligible patients were randomized into two groups and the presence of postoperative wound infection was evaluated using the Southampton wound grading system. Data were analyzed using SPSS version 21 Chicago-Illinois, statistical significance was inferred at Pvalue ≤ 0.05. RESULTS: In total 100 patients were analyzed with 20 patients excluded due to co-morbidities and noncompletion of the study. The overall prevalence of SSI was 18.0% (7 (14.0%) and 11 (22.0%) in the depilatory cream and razor shaving groups, respectively). The difference in the rate of SSI was not statistically significant (P = 0.436). Hair was completely removed in 47 (94.0%) compared to 38 (76.0%) patients in the razor shaving group (P = 0.012) while skin injuries were noted in 21 (42.0%) vs 1 (2.0%) patients who had razor shaving and chemical depilation(P = <0.0001), respectively. CONCLUSION: There was no significant difference in SSI rates in patients that had preoperative chemical depilation when compared with razor shaving.

Polypharmacy and potential drug-drug interactions for people with HIV in the UK from the Climate-HIV database.

OBJECTIVES: People with HIV (PWHIV) are likely to need therapies for comorbidities as they age. We assessed risk of drug-drug interactions (DDIs) in PWHIV. METHODS: The Climate-HIV electronic recording system was used to cross-sectionally analyse records from PWHIV aged ≥ 18 years attending four UK HIV units with a current antiretroviral (ARV) prescription in February 2018. Antiretroviral and non-ARV medications were categorized by clinical significance of DDIs (University of Liverpool DDI tool). Potential DDIs were predicted using treatment guidelines for commonly recorded comorbidities. RESULTS: Among 4630 PWHIV (44% female), 41% were ≥ 50 years old. The average number of non-ARV comedications increased from < 1 for patients aged ≤ 24 years to > 5 for patients aged ≥ 75 years; 65% were taking one or more non-ARV comedications. The median (interquartile range) number of non-ARVs was 1 (0-2) and 2 (1-5) for those aged < 50 and ≥ 50 years, respectively. Common comorbidities/concurrent health conditions occurred more frequently in patients aged ≥ 50 years vs. < 50 (53% vs. 34%). Boosted protease inhibitors were associated with the highest proportion of contraindicated comedications; dolutegravir and raltegravir had the fewest. For non-ARVs, sildenafil and quetiapine were most likely to result in DDIs. Guideline-recommended treatments for hepatitis C, hepatitis B, and tuberculosis had the highest proportions of contraindications when combined with ARV regimens, while treatments for hepatitis C, malignancy, and mental health conditions had the highest proportion of combinations potentially causing DDIs requiring dose monitoring or adjustment. CONCLUSIONS: Non-ARV use by PWHIV is high and increases with age. Treatment decisions for ageing PWHIV should consider guideline recommendations for comorbidities.

Examining Socioeconomic Status of Patients with Chronic Kidney Disease Attending Renal Clinic in Southeast Nigeria: A Single Centre Experience.

BACKGROUND: There are few reports on socioeconomic status (SES) of patients with chronic kidney disease (CKD) in Nigeria and indeed Africa, South of the Sahara. Identifying SES as an important factor for disability in people with CKD would provide a means for early identification of those at risk and, possible intervention. OBJECTIVE: To determine the SES of CKD patients attending renal clinic in the University of Nigeria Teaching Hospital. METHODS: Cross-sectional descriptive design was adopted using pretested questionnaire to elicit data on SES (age, place of residence, household asset ownership, source of drinking water; source of cooking energy; and type of toilet facility) from one hundred and forty-five (145) CKD patients attending renal clinic in the University of Nigeria Teaching Hospital. Principal component analysis was used to classify the SES into five quintiles. RESULTS: Majority of the respondents (patients) in stages 4 and 5 CKD, constituting 17.2% and 39.3% respectively were from the lower SES. There was significant correlation between SES and age of the patients; place of residence; hypertension history; ownership of some household assets; source of drinking water; source of cooking energy; and type of toilet facility. CONCLUSION: This study demonstrated that many of our patients were from the lower SES. It is recommended that both governmental and non-governmental agencies should help these patients with some form of health insurance to alleviate their healthcare cost burden.

Assessment of patients knowledge and attitude towards diabetes and its relationship with glycemic control: a cross-sectional study in a Nigerian tertiary hospital

BACKGROUND: It is postulated that increased knowledge of patients about diabetes as well as a positive attitude will lead to improved glycaemic control and better outcome. The aim of this study was to determine the knowledge and attitude of diabetic patients in a tertiary hospital in Enugu and the relationship with their glycaemic control.METHODS: A cross-sectional study was done using a structured questionnaire to obtain socio-demographic data and assess knowledge and attitude to diabetes on consecutive patients attending the outpatient clinic in a tertiary hospital. Responses were scored with equal weighting. The fasting blood glucose of the patients was measured and recorded.RESULT: There were 51(60.7%) females and 33 (39.3%) males, with majority (63.1%) in the age range 41 -64 years and 32(38.1%) had only primary education. The mean knowledge score was 6.19 ± 2.08 and 33(39.3%) demonstrated good knowledge. Knowledge did not differ between males and females (p=0.34), but was highest in those with tertiary education (p = 0.02). Positive attitude to the condition was recorded in 63(75%) subjects. There was poor correlation between knowledge and attitude (r = -0.161, p= 0.14). Those with good knowledge scores were 2 times more likely to have good glycaemic control compared with those with poor knowledge; OR = 2.015, p = 0.02. Therewas no significant difference between the glycemic control of those with good attitude and those with poor attitude (p= 0.08).CONCLUSION: Although overall knowledge was poor, patients had a good attitude to their illness. Knowledge, but not attitude was significantly positively associated with glycemic control

A cross-sectional analysis of factors associated with the intention to engage in tobacco treatment among inpatients in a state psychiatric hospital.

WHAT IS KNOWN ON THE SUBJECT?: People admitted to psychiatric facilities have high rates of tobacco use and hospitalizations present an opportunity for patients to have conversations about tobacco use treatment. Clinicians may believe that people with mental illnesses are not interested in quitting or that they do not understand the importance of treatment. Positive attitudes towards tobacco treatment, viewing that participating in treatment is normal care, and feeling that one is quite able to participate in such treatment predicts intentions to participate in treatment, which, in turn, predicts actual participation. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: Psychiatric patients who use tobacco use report poor prior involvement with tobacco treatment. Positive attitudes towards, encouraging opinions of other people about, and having a sense of control over taking part in tobacco treatment increases plans to engage in treatment. Having a sense of control in taking part in tobacco treatment is strongly associated with prior experiences with evidence-based treatment. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Because psychiatric hospitalizations are an opportunity for addressing tobacco use and treatment, clinicians should be prepared to support willing patients, especially those with prior substance use histories. Support should include providing them with information regarding tobacco treatment options during their hospital stay and ways that they can continue to receive care after discharge. Clinicians should be promoters of pro-tobacco treatment attitudes and supporting patients' sense of control over participating in treatment during hospitalization. ABSTRACT: Introduction Hospitalized tobacco users with mental illnesses (MI) may face several barriers to stopping smoking. However, motivational factors that affect the intention to engage in tobacco treatment have been shown to predict actual engagement. Aim To use the Theory of Planned Behavior to assess intentions to and prior experiences of engaging in evidence-based tobacco treatment among hospitalized individuals with MI. Method A cross-sectional survey was conducted among 115 patients in a state psychiatric hospital. Multivariate analyses were used to examine associations with the intentions and prior experiences of engaging in tobacco treatment. Results After controlling for demographic and smoking history, attitudes, subjective norms and perceived behavioural control towards engaging in tobacco treatment were significantly associated with intentions towards treatment engagement. Only higher scores on perceived behavioural control and lower education levels were associated with reported prior experiences of tobacco treatment. Discussion The low prior treatment engagement scores, but relatively higher intention to engage scores among participants suggests the need for deliberate support for evidence-based tobacco treatment during psychiatric hospitalizations. Implications for practice Clinician training in tobacco treatment can promote self-efficacy to engage patients while supporting patients' control so that tobacco treatment is an expected component of psychiatric care.

A retrospective analysis of the comparative effectiveness of smoking cessation medication among individuals with mental illness in community-based mental health and addictions treatment settings.

WHAT IS KNOWN ON THE SUBJECT?: Persons with different mental illnesses smoke for reasons based on their particular diagnosis. As compared to those without, persons with mental illnesses are less able to quit smoking when using smoking cessation medications. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This paper shows that there may be differences in the ability to quit smoking between persons with different mental illness diagnoses. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Clinicians should be aware that persons with anxiety disorders may find it more difficult to quit smoking as compared to those with other mental illnesses. Clinicians should be aware that of all medications, varenicline seems to help those with mood disorders to quit the best. Clinicians should be aware that persons with psychotic disorders likely need longer treatment durations for smoking cessation as compared to persons with other mental illnesses. ABSTRACT: Introduction Individuals with mental illnesses (MI) have diagnosis-specific reasons for smoking and achieve low smoking cessation when using cessation medications. Aim To assess differences in smoking cessation outcomes by MI diagnosis and cessation medications in outpatient mental health and addictions treatment settings in Vancouver, Canada. Method This is a retrospective analysis of tobacco treatment outcomes from 539 participants. The programme consists of cessation pharmacotherapy with 8 to 12 weeks of behavioural counselling and 12 weeks of support group. Smoking cessation was verified by expired carbon monoxide levels. Generalized estimating equations models assessed differences in cessation by type of medication in both total and stratified samples. Results There were no significant differences in cessation by pharmacotherapy in the total sample. Individuals with a mood disorder were two times more likely to achieve cessation as compared to those with an anxiety disorder. Among individuals with mood disorders, receiving varenicline alone resulted in three times the likelihood of cessation as compared to receiving single NRT. Discussion The differences in outcomes by MI diagnosis suggest the need for more diagnosis-specific approaches to optimize cessation. Implications for Practice Compared with other diagnoses, persons with anxiety disorders may have a greater challenge quitting and those with a psychotic disorder may require longer treatment durations.

Primary hypertension among a population of Nigerian secondary school adolescents: Prevalence and correlation with anthropometric indices: A cross-sectional study.

AIM: To assess the prevalence of primary hypertension and its correlation with anthropometric indices among a population of Nigerian adolescents. MATERIALS AND METHODS: A cross-sectional study of secondary school adolescents aged 10-19 years in Enugu, Nigeria, using multi-staged sampling method. Anthropometry and blood pressures were measured using standardized instruments. Data analysis was with the Statistical Package for Social Sciences (SPSS) Version 20.0 (Chicago, IL, USA). RESULTS: A total of 2419 adolescents (mean age, 14.80 ± 2.07 years) were included in the study. Prevalence of hypertension was 10.7%. Systolic and diastolic hypertension were observed in 232 (9.6%) and 85 (3.5%) of the participants, respectively. Forty-two of the 137 obese (30.7%) compared to 158 among the 1777 (7.7%) with normal body mass index (BMI) (P < 0.001) had systolic hypertension. Waist circumference (r = 0.37) and BMI (r = 0.37) significantly and positively correlated with systolic hypertension. CONCLUSION: Obese and overweight adolescents had higher prevalence of primary hypertension than their counterparts with normal BMI.

Overall Survival and Response to Systemic Therapy in Metastatic Extrauterine Leiomyosarcoma.

Background. Leiomyosarcomas (LMS) represent a heterogeneous subset of soft tissue sarcomas. Factors influencing prognosis for patients with metastatic extrauterine LMS (euLMS) are not well described. Limited data are available regarding responses to systemic therapy. Methods. We collected clinical and pathologic information for all patients with metastatic euLMS seen at Memorial Sloan Kettering Cancer Center between 1989 and 2012. Objective responses to first-line therapy were analyzed for a subset of patients with available baseline and on-treatment imaging using RECIST 1.1. Results. 215 patients with metastatic euLMS had a median overall survival (OS) of 2.6 years from the time of metastasis. Older age, male sex, and ≥3 initial sites of metastasis were associated with worse OS on multivariate analysis. Objective response rate (ORR) in N = 113 was 19% overall and 25%, 26%, and 25% for gemcitabine, gemcitabine plus docetaxel, and anthracycline-alkylator combinations. Patients whose tumors objectively responded to first-line therapy had a lower risk of death versus those who did not (Hazard Ratio 0.46; 95% CI: 0.26-0.79, p = 0.005). Conclusions. Anthracycline- and gemcitabine-based regimens have similar activity in this cohort of euLMS. Prognostic factors for OS include older age, male sex, and ≥3 initial sites.

A systematic review of tobacco use among adolescents with physical disabilities.

OBJECTIVE: To provide a systematic review of tobacco use among adolescents with physical disabilities. STUDY DESIGN: A systematic review. METHODS: A search was performed of English articles published prior to December 2014 in the PubMed database for studies examining smoking rates among adolescents with and without physical disabilities. Ten studies were retrieved (all cross-sectional surveys) of which six compared adolescent populations from nationally representative samples and four examined those based on convenience sampling. Pooled analyses of smoking rates by disability status were performed. RESULTS: In studies from nationally representative samples (n = 6 studies), adolescents with physical disabilities were significantly more likely to use tobacco as compared to adolescents without (pooled analyses = 29.7% vs 23.3%). However, in studies from non-representative samples, adolescents with physical disabilities were less likely to use tobacco as compared to adolescents without (pooled analyses = 22.7% vs 39.1%). CONCLUSIONS: Adolescents with physical disabilities may have an increased risk of tobacco use relative to those without disabilities. Tailored tobacco use prevention and cessation strategies may be appropriate for this high-risk population. Future longitudinal studies which determine factors associated with tobacco use among adolescents with different disabilities should be considered to reduce the disproportionate tobacco use in this population.

Refractive Amblyopia among children in Ibadan: the need for amblyopia screening programmes.

BACKGROUND: The prevalence and burden of amblyopia in developing countries is probably underestimated, and little is known about the pattern of amblyopia in West Africa. AIM: To determine the relative frequency and types of amblyopia among children with refractive errors seen in the eye clinic of a tertiary hospital over a 2 year period. METHODS: A cross-sectional study conducted at the eye clinic of the University College Hospital, Ibadan, Nigeria between January 2012 and December 2013. Case notes of children with refractive errors seen during this period were retrieved and information including socio-demographic data, presenting visual acuity and visual acuity with correction were recorded. Amblyopia was defined as best corrected visual acuity worse than 6/9 or a difference of ≥ 2 Snellen chart lines between both eyes in the absence of any ocular pathology that could explain the visual impairment. RESULTS: A total of 250 eligible patients who had refractive errors were included in the study. Visual acuity was corrected to 6/9 or better in 224 (89.6%) children while 26 (10.4%) of them had amblyopia. Among the 26 children with amblyopia, 21 (80.8%) children had amblyopia in both eyes and majority (65.4%) had iso-ametropic amblyopia. Of the 47 amblyopic eyes, 36 (76.6%) eyes had moderate amblyopia while 11 (23.4%) eyes had severe amblyopia. CONCLUSION: There is a high relative frequency of amblyopia in this study and we recommend preschool eye examinations for all children to ensure early detection and management of amblyopia, thereby reducing the burden of amblyopia in our populace.

Carrier status of leptospirosis among cattle in Sri Lanka: a zoonotic threat to public health.

Leptospirosis is a zoonotic disease of global importance and one of the notifiable diseases in Sri Lanka. Recent studies on human leptospirosis have suggested that the cattle could be one of the important reservoirs for human infection in the country. However, there is a dearth of local information on bovine leptospirosis, including its implications for human transmission. Thus, this study attempted to determine the carrier status of pathogenic Leptospira spp in cattle in Sri Lanka. A total of 164 cattle kidney samples were collected from the meat inspection hall in Colombo city during routine inspection procedures conducted by the municipal veterinary surgeons. The DNA was extracted and subjected to nested PCR for the detection of leptospiral flaB gene. Amplicons were sequenced, and phylogenic distances were calculated. Of 164 samples, 20 (12.2%) were positive for flaB-PCR. Sequenced amplicons revealed that Leptospira species were deduced to L. borgpetersenii (10/20, 50%), L. kirschneri (7/20, 35%) and L. interrogans (3/20, 15%). The results indicate that a high proportion of the sampled cattle harbour a variety of pathogenic Leptospira spp, which can serve as important reservoirs for human disease.

Malaria diagnosis and treatment amongst health workers in University of Nigeria Teaching Hospital, Enugu, Nigeria.

BACKGROUND: Confirmation of malaria and appropriate treatment are keys to malaria control. OBJECTIVE: To determine the practice of malaria diagnosis and treatment in a Nigerian tertiary hospital. MATERIALS AND METHODS: Retrospective review of patients' records at the Children's Clinic in UNTH. RESULTS: Out of 6,684 children seen within the one year reviewed period, children diagnosed with malaria were 35.8 percent. Males were 60 percent and females were 40 percent. Children under five years were 72.6 percent of the total. Folders successfully traced were 1012; in 92 percent investigations for malaria were requested while 32 percent had differential diagnosis. Out of the 931 malaria investigations requested, 30 percent did the tests and positive results were 94.9 percent. Presumptive treatment was 98 percent. Majority (83.3%) received ACTs. CONCLUSION: The practice of presumptive treatment was high and few cases had a differential diagnosis. Training of health workers on the need to confirm malaria cases is required.

Sex differences in smoking initiation among children and adolescents.

OBJECTIVE: To understand differences in the context of, and reasons for, smoking initiation among boys and girls. STUDY DESIGN: Sex- and gender-based analysis of published literature. METHODS: A comprehensive search of the PUBMED database was conducted for studies (published in the English language) between January 1980 and October 2010 that assessed smoking initiation among children and adolescents (aged 8-19 years). Information on demographics and study design were extracted by two authors from each eligible article. A sex- and gender-based analysis was employed. RESULTS: Of 40 publications initially obtained, studies in adult or college-age populations (n = 9) and studies that did not examine the specific context of smoking initiation (n = 19) were excluded. Thus, this review is based on 12 eligible studies. Eligible studies represented data from 10,831 children and adolescents in nine countries. In most studies, boys had a lower age of smoking initiation than girls, with the exception of two studies from Yemen and China. In some countries, girls reported obtaining and smoking their first cigarette from family members at home. In most studies, the school was the main setting for initiation for boys, whereas the home setting was the main setting for girls. CONCLUSIONS: This study highlights gender and cultural differences in smoking initiation among children and adolescents. Smoking prevention programmes should thus include gender- and culture-specific content related to smoking initiation. Future studies may further examine gender- and culture-specific messaging to inform policies and enhance tailored programmes aimed at preventing smoking initiation.

Sex differences in nicotine dependence among addictions clients accessing a smoking cessation programme in Vancouver, British Columbia, Canada.

Most individuals in drug treatment programmes use tobacco and are dependent on nicotine. For 323 participants (65% men, mean age = 49.3 years) with a history of substance use disorder (SUD) and/or psychiatric disorders (PD) enrolled in a tobacco dependence clinic programme, we compared baseline characteristics among women and men and examined factors associated with nicotine dependence (ND). Individuals with mood, anxiety and psychotic disorders were more likely to be female, whereas men were more likely to be characterized by alcohol, cocaine and marijuana use, older age, older age at smoking initiation and higher confidence in quitting smoking scores. In stratified multivariate analyses, among women, history of an anxiety disorder and a greater number of cigarettes smoked per day were associated with higher ND scores; among men, a greater number of cigarettes smoked per day and higher confidence in quitting scores were associated with higher ND scores. Given the differences in smoking, SUD and PD histories between women and men accessing addiction treatment, and differential associations with ND, it is important to further explore factors that may enhance tailored treatments and inform future studies examining biological and psychosocial factors for tobacco use in SUD and PD treatment populations.

Nicotine dependence and gender differences in smokers accessing community mental health services.

Despite evidence of differences in smoking behaviour between women and men, few studies have assessed these differences in individuals with mental illnesses. In this cross-sectional study, we explored gender differences in smoking behaviour among 298 individuals (60% male) accessing community mental health services. Individuals with a psychotic disorder as compared with a non-psychotic disorder, and individuals using a greater number of substances were more likely to be male. Readiness to change, daily cigarette consumption and level of nicotine dependence did not differ between men and women; however, subjective ratings of tobacco addiction were higher in women than in men. Among women, only scores on the subjective tobacco addiction scale were associated with nicotine dependence, while among men, a variety of variables were associated with nicotine dependence. These factors are important for understanding individual differences in tobacco dependence among clients with mental illnesses, and are expected to inform future studies examining tobacco use in mental health treatment populations.

Studies on the possible mechanisms of antidiabetic activity of extract of aerial parts of Phyllanthus niruri.

CONTEXT/OBJECTIVES: The effects of methanol extract of aerial parts of Phyllanthus niruri L. (Euphorbiaceae), an antidiabetic herb, on glucose absorption and storage in diabetes were studied to elucidate the mechanisms of blood glucose lowering and glycemic control in diabetes. METHODS: The effect of chronic oral administration of the extract on glycemic control was evaluated in alloxan diabetic rats using blood glucose lowering and post-prandial glucose suppression activities as well as effects on hemoglobin glycation and body weight. Effects on glucose mobilization and storage were assessed using the weight and glycogen content of liver isolated from treated diabetic rats, while in vitro inhibition of α-amylase and α-glucosidase enzyme activities were used as indices of effect on glucose absorption. RESULTS: Results showed that the extract lowered blood glucose, suppressed postprandial rise in blood glucose following a glucose meal, reduced hemoglobin glycation and increased absolute and relative weights as well as glycogen content of liver in diabetic rats. Treatment with the extract also ameliorated the decrease in body weights caused by the diabetic disease. In vitro, the extract inhibited α-amylase (IC50: 2.15 ± 0.1 mg/mL) and α-glucosidase (IC50: 0.2 ± 0.02 mg/mL) activities. DISCUSSION AND CONCLUSION: These findings suggest that aerial parts of P. niruri may owe their blood glucose lowering properties to inhibition of glucose absorption and enhancement of glucose storage.
