Although classified by the Joint Monitoring Programme (JMP) as unimproved sanitation facilities, public toilets still play a critical role in eliminating open defecation in informal settlements. We explored perspectives of toilet operators on opportunities and barriers to operation and maintenance (O&M) of public toilets in informal settlements. A cross-sectional study design was used. Up to 20 in-depth interviews were used to obtain data on the experiences of public toilet operators. Thematic content analysis was used.

Ressults show that opportunities for improving O&M include; operation of public toilets is a source of livelihood; operators are knowledgeable on occupational risks, and the community is involvedin sanitation activities. Barriers to effective O&M include; high operation costs, failure to break even and a lack of investments in occupational health Therefore, there is need to recognise the significance of public toilets as a viable alternative to open defecation in areas where ownership of private sanitation facilities is difficult. Failure to observe the health and safety of toilet operators may further compromise O&M.  相似文献

The molluscicidal potency of ground seed pods of Swartzia madagascariensis was tested in the laboratory against Marisa cornuarietis, a well known competitor and/or predator of pulmonate intermediate hosts of schistosomiasis. Results showed that a minimum concentration of 1.6g ground pods/1 was required to cause 100% mortality in M. cornuarietis. This concentration was by far over and above what is required (ie, 100 mg ground pods/1) to kill 10% of the pulmonate hosts of schistosomiasis. It seems that the application of S. madagascariensis at a concentration inimical to pulmonates (ie, 100 mg ground ponds/1 or slightly higher) in habitats where M. cornuarietis is introduced may not adversely affected to competitor snail population. Hence, the prospect of using S. madagascariensis in conjunction with M. cornuarietis against pulmonate snail hosts is conceived and tentatively recommended.  相似文献

All cases of acute intermittent porphyria (AIP) are believed to be caused by a mutation in the gene encoding for porphobilinogen deaminase, a rate-limiting enzyme in the haem synthetic pathway. This gene has been mapped to the long arm of chromosome 11, a region of the genome that has recently attracted considerable attention as a possible location for genes implicated in major mental disorder. This study was designed to show whether major mental illness co-segregated with acute intermittent porphyria in families where the two conditions are found. The study also investigated the relation between clinical mental symptoms and biochemical parameters of acute intermittent porphyria. The case records of 344 consecutive patients admitted to the Porphyrias Research Group in the Western Infirmary in Glasgow between 1950 and 1988 with acute intermittent porphyria were examined for evidence of psychiatric contact. Of 16 individuals identified, 12 were available for the study. Forty relatives of these 12 probands, including 9 who were asymptomatic carriers of AIP, were interviewed for lifetime history of mental illness and current symptoms. Comparisons were made between 4 groups of patients based on urinary porphyrin levels and erythrocyte enzyme activity; 1) manifest acute intermittent porphyria, 2) latent acute intermittent porphyria, 3) normal relatives and 4) total acute intermittent porphyria (latent and manifest combined). No association was found between AIP and schizophrenia or manic-depressive illness. Only one patient with schizophrenia was found in the sample of 344 case notes, and in 2 families bipolar illness was found but did not segregate with acute intermittent porphyria. The commonest psychiatric diagnosis in patients was generalized anxiety. In the total AIP group (latent and manifest), compared with normals, the rating scale measures of anxiety were significantly correlated with the level of porphyrin metabolites in the urine at the time of rating. This was true even in subjects with latent AIP, who were not at the time of testing aware that they were asymptomatic carriers of the illness. AIP should be considered in the differential diagnosis of generalized anxiety disorder.  相似文献

BACKGROUND: We carried out a large randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behaviour therapy (MACT) versus treatment as usual (TAU) for deliberate self-harm. METHOD: Patients presenting with recurrent deliberate self-harm in five centres were randomized to either MACT or (TAU) and followed up over 1 year. MACT patients received a booklet based on cognitive behaviour therapy (CBT) principles and were offered up to five plus two booster sessions of CBT from a therapist in the first 3 months of the study. Ratings of parasuicide risk, anxiety, depression, social functioning and global function, positive and negative thinking, and quality of life were measured at baseline and after 6 and 12 months. RESULTS: Four hundred and eighty patients were randomized. Sixty per cent of the MACT group had both the booklet and CBT sessions. There were seven suicides, five in the TAU group. The main outcome measure, the proportion of those repeating deliberate self-harm in the 12 months of the study, showed no significant difference between those treated with MACT (39%) and treatment as usual (46%) (OR 0.78, 95% CI 0.53 to 1.14, P=0.20). CONCLUSION: Brief cognitive behaviour therapy is of limited efficacy in reducing self-harm repetition, but the findings taken in conjunctin with the economic evaluation (Byford et al. 2003) indicate superiority of MACT over TAU in terms of cost and effectiveness combined.  相似文献

ObjectivesQuantify how observable characteristics contribute to influenza vaccination disparities among White, Black, and Hispanic nursing home (NH) residents.DesignRetrospective cohort.Setting and ParticipantsShort- and long-stay U.S. NH residents aged ≥65 years.MethodsWe linked Minimum Data Set (MDS) and Medicare data to LTCFocUS and other facility data. We included residents with 6-month continuous enrollment in Medicare and an MDS assessment between October 1, 2013, and March 31, 2014. Residents were classified as short-stay (<100 days in NH) or long-stay (≥100 days in NH). We fit multivariable logistic regression models to assess the relationships between 27 resident and NH-level characteristics and receipt of influenza vaccination. Using nonlinear Oaxaca-Blinder decomposition, we decomposed the disparity in influenza vaccination between White versus Black and White versus Hispanic NH residents. Analyses were repeated separately for short- and long-stay residents.ResultsOur study included 630,373 short-stay and 1,029,593 long-stay residents. Proportions vaccinated against influenza included 67.2% of White, 55.1% of Black, and 54.5% of Hispanic individuals among short-stay residents and 84.2%, 76.7%, and 80.8%, respectively among long-stay residents. Across 4 comparisons, the crude disparity in influenza vaccination ranged from 3.4 to 12.7 percentage points. By equalizing 27 prespecified characteristics, these disparities could be reduced 37.7% to 59.2%. Living in a predominantly White facility and proxies for NH quality were important contributors across all analyses. Characteristics unmeasured in our data (eg, NH staff attitudes and beliefs) may have also contributed significantly to the disparity.Conclusions and ImplicationsThe racial/ethnic disparity in influenza vaccination was most dramatic among short-stay residents. Intervening on factors associated with NH quality would likely reduce these disparities; however, future qualitative research is essential to explore potential contributors that were unmeasured in our data and to understand the degree to which these factors contribute to the overall disparity in influenza vaccination.  相似文献

Background

The ongoing Boko Haram insurgency in northeastern Nigeria has depleted the country’s capability to deliver quality healthcare to her citizenry. The ailing health sector is overwhelmed with a rising incidence and prevalence of infectious and non-communicable diseases.

Aim

The aim of this paper was to determine the trend of kidney disease, end-stage renal disease (ESRD), anaemia, malnutrition and human immunodeficiency virus (HIV) in northeastern Nigeria.

Materials and methods

Data covering different periods between 1999 and 2017 were obtained from the University of Maiduguri Teaching Hospital (UMTH), Maiduguri in northeastern Nigeria. This hospital is the largest tertiary healthcare facility in the region. The data were demographic in nature, i.e. sex, age or simply the registered cases. A quadratic model of time-series analysis was used to create the various trends of the respective diseases with the aid of Minitab software (version 18.0). t-Tests and analysis of variance (ANOVA) were also performed, with a p-value of less than or equal to 0.05 being considered significant.

Results

About three out of every five patients treated for kidney disease were male, while three out of every five patients treated for HIV were female. Patients between the ages of 31 and 50 years were at the greatest risk of developing kidney disease. The mean distribution of disease incidence was the same for both sexes for kidney disease, anaemia, malnutrition and HIV. The mean distribution disease incidence was different between age groups for kidney disease but the same for anaemia. The incidence of anaemia and malnutrition reported was almost the same for both sexes. Children under the age of 10 years old were at the most risk of anaemia, with the distribution decreasing with increasing age. The trend analysis of the incidence of kidney disease, ESRD, anaemia and malnutrition showed that these ailments were on the increase, while the number of patients that were on antiretroviral therapy (ART) was on the decline in northeastern Nigeria.

Conclusion

These increasing trends are evidences of the effect of Boko Haram on the public health of the people of northeastern Nigeria and will continue to be a public health concern for the region and the country as a whole.

Surface-exposed proteins are important serotype markers in Streptococcus agalactiae (group B streptococci; GBS). The proteins include the c proteins c(alpha) and c(beta), the R4 protein and a protein provisionally called P. For all of these markers, protein-specific monoclonal antibodies (MAbs) have been generated. We have compared whole-cell-based fluorescent antibody testing (FAT), ELISA, and dot blotting for MAb-based detection of these proteins by testing a panel of 52 GBS isolates of different capsular antigen types. Of a total of 208 observations with each of the tests, positive signalling in the dot assay was observed in 32.2%, with ELISA in 27.8%, and with FAT in 26.4% of the recordings. Discordant results were noted most frequently with the c(beta) and c(alpha) MAbs. In the case of c(alpha) the reason for the discordant test results was further examined and it appeared that this could be attributed to low level expression of the c(alpha) protein, although structural variations of c(alpha) proteins cannot be excluded. Our findings favour dot blotting as the method of choice although we consider all three methods acceptable for serotyping of GBS.  相似文献

OBJECTIVES: To determine the concentrations of iron and alcohol in traditional beer, as well as how these may be related to the brewing process. DESIGN: Cross sectional study. SETTING/SUBJECTS: Rural communities living in four of Zimbabwe's nine provinces. MAIN OUTCOME MEASURES: Ionic iron concentration and alcohol concentration in 94 different types of alcoholic beverages prepared in rural areas, and 18 commercially produced beers. RESULTS: The commonest types of traditional beer were a seven day beverage called 'doro rematanda', a by-product of this seven day beer called 'muchaiwa,' and a one-day beverage called 'chikokiyana'. Methods of preparation were similar in the four provinces. Median (Q1, Q3) ionic iron concentrations were 52 (31 to 75) mg/L for the seven-day beer (n = 51), 24 (18 to 36) mg/L for muchaiwa (n = 30) and 21 (17 to 63) mg/L for chikokiyana (n = 13). In contrast, ionic iron concentrations in 12 samples of commercially prepared clear beers were 0.1 mg/L and in commercial opaque beer were 3.6 mg/L. Mean (SD) alcohol concentration in traditional beer was 4.1 g/100 ml (+/- 0.873) compared to 2.8 g/100 ml +/- 1.394) in the muchaiwa and 3.6 g/100 ml (+/- 1.445) in the one day brew, chikokiyana. Mean alcohol concentrations in the three commercial beers are reportedly 3.5 g/100 ml in the opaque beer (Scud), and 4.7 to 5.0 g/ml in clear beer (Zambezi and Castle lagers). CONCLUSIONS: Several preparation methods lead to traditional fermented beverages with very high iron concentrations. Measures to prevent dietary iron overload should include all of these beverages in their scope.  相似文献

Several factors which affect bone density and predict risk of osteoporosis (e.g., ethnic origin, amenorrhea) are reportedly associated with a higher incidence of stress fracture in active premenopausal women. The authors surveyed 2,312 active duty Army women for the prevalence of ever having been diagnosed ("told by a doctor") with a stress fracture (16.1% of respondents) and examined the relationship between surveyable risk factors for low bone density and this self-reported stress fracture history (self-reported SF). Current smoking, previous history of amenorrhea (menses absent greater than 6 months), and known family history of osteoporosis were significantly associated with self-reported SF, while black ethnic origin was a protective factor. These data suggest hypotheses of stress fracture pathogenesis in Army women which bear further testing.  相似文献
