AbstractBackgroundDiarrheal disease is one of the leading causes of morbidity and mortality globally, particularly in children under 5 years of age. Factors related to diarrheal disease incidence include infection, malnutrition, and exposure to contaminated water and food. Climate factors also contribute to diarrheal disease.ObjectivesWe aimed to explore the relationship between temperature, precipitation and diarrhea case counts of hospital admissions among vulnerable communities living in a rural setting in South Africa.MethodsWe applied a novel approach of ‘contour analysis’ to visually examine simultaneous observations in frequencies of anomalously high and low diarrhea case counts occurring in a season and assigning colors to differences that were statistically significant based on chi-squared test results.ResultsThere was a significantly positive difference between high and low ‘groups’ when there was a lack of rain (0 mm of cumulative rain) for 1 to 2 weeks in winter for children under 5.Diarrhea prevalence was greater among children under 5 years when conditions were hotter than usual during winter and spring.DiscussionDry conditions may lead to increased water storage raising the risks of water contamination. Reduced use of water for personal hygiene and cleaning of outdoor pit latrines affect sanitation quality. Rural communities require adequate and uninterrupted water provision and healthcare providers should raise awareness about potential diarrheal risks especially during the dry season.

Diarrheal disease is one of the leading causes of morbidity and mortality globally, particularly in children under 5 years of age. Factors related to diarrheal disease incidence include infection, malnutrition, and exposure to contaminated water and food. Climate factors also contribute to diarrheal disease. We aimed to explore the relationship between temperature, precipitation and diarrhoea case counts of hospital admissions among vulnerable communities living in a rural setting in South Africa. We applied ‘contour analysis’ to visually examine simultaneous observations in frequencies of anomalously high and low diarrhoea case counts occurring in a season, and assigning colours to differences that were statistically significant based on chi-squared test results. Children under 5 years of age were especially vulnerable to diarrhoea during very dry, hot conditions as well as when conditions were wetter than usual. We saw an anomalously higher number of diarrhoea cases during ‘warmer than usual’ conditions in the dry winter season, with average winter temperatures in Limpopo being from about 5 to 10 °C. As for ‘wetter than usual’ conditions, we saw an anomalously higher number of diarrhoea cases during ‘drier than usual’ conditions for the winter and spring. The lagged association seen in cumulative rainfall could not be distinguished in the same way for temperature-related variables (indicating rainfall had a larger impact on higher cases of diarrhoea), nor for the older age group of 5 years and older. Dry conditions were associated with diarrhoea in children under 5 years of age; such conditions may lead to increased water storage, raising the risks of water contamination. Reduced use of water for personal hygiene and cleaning of outdoor pit latrines also affect sanitation quality. Rural communities require adequate and uninterrupted water provision, and healthcare providers should raise awareness about potential diarrhoeal risks, especially during the dry season as well as during wintertime when conditions are warmer than usual.

Aim: “Diarrhea has been a common cause of morbidity and mortality in children under 5 years old. This study was intended to assessment level of personal hygiene, type of water taken by children, crowding index and some factors associated with some bacterial infection in children under 5 years.”Material and Methods: This study enrolled 143 children under 5 years with clinical evidence of diarrheal disease through the period extending from 15/4/2016 to 30/8/2016, who were admitted to Baghdad teaching hospital,   stool samples were collected from children who had diarrhea were inoculated on selective culture media using standard method. “The isolate were identified depending on morphological feature of colonies and from all media biochemically using API 20E system.”Results: A total bacterial infection was observed (13.9%). Specific prevalence of species bacteria is as follows,” E.coli (7.7%), and Shigella spp. (2%), and Salmonella spp. (3.5%) and V. cholera (0.7%).” Finding from our study indicate that patient in the age group >5 years of age were more likely to have diarrhea than those who were younger, and Children that consumed tap water were more infected with bacteria (9.7%). In this study, crowding index were associated with diarrheal disease,” children from households with 1 or 2 people per room were (1.4%) less likely to have diarrhea compared to children from household with more than 3 people per room (30%). Our results indicate that availability of house hold sanitation facilities, access to filter and clean water, good personal hygiene and butter nutrition were all associated with lower incidence of diarrhea.”

SUMMARYThis study compares the seasonality of rotavirus diarrhoeal hospital admissions and its relationship to climatic factors across three Australian cities. Weekly admission of rotavirus diarrhoea (1993–2003) in children aged <5 years and weekly average temperature and relative humidity for each city were modelled using a log-linear model with a cubic trend and season. Interactions were included to test for differences in the effect of temperature and humidity between seasons and between cities. Admissions of rotavirus diarrhoea peaked in winter and spring and were lowest in summer. Higher temperature and humidity in the previous week were associated with a decrease in rotavirus diarrhoeal admissions in three cities. The effects of both temperature and humidity on rotavirus admissions in Brisbane differed across seasons. Strategies to combat outbreaks of rotavirus diarrhoea should take climatic factors and seasonal effects into consideration to plan for the excess seasonal hospital admissions.

  ABSTRACT Diarrhea is cause the number one of a death in the world. The united Nation Children’s Found (UNICEF) thinks about every 30 second there one a child die because diarrhea. Diarrhea disease still be a problem for society healthy in Indonesia well reviewed of morbidity and mortality ant the mark of deaths and “Kejadian Luar Biasa (KLB)” that caused. Accrodin to WHO the mark of diarrhea illness 2010 is 411 patients per 1.000 population. The digit of death diarrhea is 14% from the digit of death over all. The purpose of this research to know a connection between education and mother economic status with toodler (children under 5 years old) diarrhea case at Puskesmas Sekip Palembang in February 2014. Desaign of this research to survey analitic by do coloser Cross Sectional in Accidental Sampling tehnic which one the variable who get research, include education and mothers economic status. The sampel in this research in 33 mothers who come by bring their toodler to MTBS Puskesmas Sekip Palembang at February 2014. Each variabel who get research, then get analysis by use analysis Chi-Square by decisios X² table (3,481). The result of this research show that the respondent by diarrhea as many is 15 respondent (45,5%) and didn’t diarrhea 18 respondent (54,5%). This of high education 13 repondent (39,4%) and less education is many as 20 respondent (60,6%), the respondent based to the high economic status as many as 13 respondent (39,4%). From statistic test Chi-Square show that, there a connection between education  with diarrhea case in X² count = 4,313, and there a connection between mothers economic status with case diarrhea at X² count= 4,917. From the results of this study are expected to further improve health education, especially regarding the incidence of diarrhea in infants to mothers who have young children understand more about the incidence of diarrhea.     ABSTRAK Diare adalah penyebab nomor satu kematian di dunia. The United Nations Children’s Fund (UNICEF) memperkirakan bahwa setiap 30 detik ada anak meninggal karena diare. Penyakit diare masih merupakan masalah kesehatan masyarakat di Indonesia baik ditinjau dari angka kesakitan dan angka kematian serta kejadian luar biasa (KLB) yang ditimbulkan. MenurutWHO angka kesakitan diare pada tahun 2010 yaitu 411 penderita per 1000 penduduk. Angka kematian diare 14% dari angka kematian balita secara keseluruhan. Tujuan penelitian ini untuk mengetahui hubungan antara pendidikan dan status ekonomi ibu dengan kejadian diare pada balita di Puskesmas SekipPalembang pada bulan Februari Tahun 2014. Desain penelitian ini adalah survey analitik dengan pendekatan Cross Sectional dalam teknik Accidental Sampling dimana variableyang diteliti meliputi pendidikan dan status ekonomi ibu. Sampel pada penelitian ini adalah 33ibu yang datang membawa anak balitanya berobat ke MTBS puskesmas Sekip Palembang pada bulan FebruariTahun 2014. Masing-masing variabel yang diteliti kemudian dianalisa dengan menggunakan analisis Chi-Square dengan ketetapan X² Tabel (3,481).

UNSTRUCTURED The seasonality of influenza viruses and endemic human coronaviruses was tracked over an 8-year period to assess key epidemiologic reduction points in disease incidence for an urban area in the northeast United States. Patients admitted to a pediatric hospital with worsening respiratory symptoms were tested using a multiplex PCR assay from nasopharyngeal swabs. The additive seasonal effects of outdoor temperatures and indoor relative humidity (RH) were evaluated. The 8-year average peak activity of human coronaviruses occurred in the first week of January, when droplet and contact transmission was enabled by the low indoor RH of 20-30%. Previous studies have shown that an increase in RH to 50% has been associated with markedly reduced viability and transmission of influenza virus and animal coronaviruses. As disease incidence was reduced by 50% in early March, to 75% in early April, to greater than 99% at the end of April, a relationship was observed from colder temperatures in January with a low indoor RH to a gradual increase in outdoor temperatures in April with an indoor RH of 45-50%. As a lipid-bound, enveloped virus with similar size characteristics to endemic human coronaviruses, SARS-CoV-2 should be subject to the same dynamics of reduced viability and transmission with increased humidity. In addition to the major role of social distancing, the transition from lower to higher indoor RH with increasing outdoor temperatures could have an additive effect on the decrease in SARS-CoV-2 cases in May. Over the 8-year period of this study, human coronavirus activity was either zero or >99% reduction in the months of June through September, and the implication would be that SARS-Cov-2 may follow a similar pattern.

Section 136 of the Mental Health Act 1983 is used by police officers to detain persons who they feel might be suffering with mental disorder until a formal Mental Health Act assessment can be undertaken. Previous studies have shown that the outcomes of these assessments result in remarkably different rates of subsequent hospital admissions. Within a rural setting it has also been shown that the rate of use of Section 136 varies considerably. This study examines the use of Section 136 within a family of eight police forces that have been matched to ensure that they cover similar populations. The results show that there are considerable variations in the use of Section 136, with the Devon and Cornwall region using the section over two and a half times the mean for the group. Possible reasons for this discrepancy are discussed.

Introduction: Historically, 2 methods have been used to determine the incidence of Kawasaki disease (KD): active or passive surveillance, or the use of administrative databases. Given the increasing regulatory requirements, mainly around patient privacy, periodic retrospective surveillances have become increasingly challenging. Administrative databases are not curated datasets and doubts have been cast on their accuracy. Methods: The Hospital for Sick Children has been conducting retrospective triennial surveillances of KD since 1995 by contacting all hospitals in Ontario and manually reviewing all cases through chart review, reconciling inter-hospital transfers and multiple readmissions. We queried the Canadian hospital discharge database (Canadian Institute for Health Information) for hospitalizations associated with a diagnosis of KD between 2004-9. The administrative dataset was manually reviewed; patient national health number, institution and dates of admission/discharge were used to identify inter-hospital transfers, readmission and follow-up episodes. Results: The Canadian hospital discharge database reported 1,685 admissions during the study period (281±44 per year) for Ontario. Manual review of the dataset identified 219 (13%) as inter-hospital transfers (56, 26%), readmissions (122, 56%), admissions for follow-up of coronary artery aneurysms (14, 6%) or hospital admissions not related to KD (27, 12%). When these admissions were removed, the total number of incident cases for the study period was 1,466 (244±45 per year). The retrospective triennial surveillance identified 1,373 KD cases during the same period (229±33 per year). The Canadian hospital discharge database overestimated the number of cases in all 6 years by an average of 6.7±5.9%. The overestimation likely comes from patients who were originally diagnosed with KD but in whom the diagnosis of KD was subsequently excluded (historically ~5-6%). Conclusions: Reliance on administrative data to determine incidence of KD is possible and accurate; data should be manually reviewed to remove non-incident cases and estimates should be adjusted to reflect the expected proportion of patients in whom the diagnosis of KD will be subsequently excluded.

Preventable factors such as infectious diseases (pneumonia, diarrhea, and malaria), malnutrition and neonatal complications are still the leading cause of child mortality worldwide 1 In 2013, it is estimated that 6.3 million babies born worldwide died before the age of 5, and approximately 9.2% of these deaths were due to diarrheal diseases 2, 3 in simple, accessible ways, and effective treatment can reduce diarrhea-related mortality and make hospital admissions unnecessary, and the role of mothers is the most important 4. Since the presentation of Oral Rehydration Therapy (ORT) in 1979, mortality has reduced. Diarrhea has had a steady downward trend 5. If mothers who have children under 5 years of age, used correctly ORS, they could easily resolve the problem of dehydration in acute diarrhea 6. Mothers didn’t use correctly ORS because of their Low literacy and lack of knowledge and wrong attitude about ORT7. Some health care workers provide mothers’ required equipments, regardless of their educational needs, and mothers may not use ORS. In this study, health workers identified mothers' educational needs and subsequently they trained them about using ORS at home in acute diarrhea in children under 5 years of age

Foliar symptoms of Eutypa dieback, caused by Eutypa lata, in grapevines, cv. Shiraz, varied from year to year in a 6-year study conducted in South Australia and, although trends were similar for vineyards within geographical regions, differences were observed between regions. We attempted to elucidate the causes underlying this variation and hypothesized that it was influenced by climatic factors. A number of possible relationships were identified between climate and symptom expression: (i) increased symptom expression was related to increased winter rainfall 18 months earlier, (ii) decreased disease incidence and prevalence were related to increased temperature in spring, and (iii) a reduction in disease incidence was related to both very high and very low rainfall in October. Theories for these relationships are proposed and require further investigation. A conceptual model was developed which requires validation and has the potential to predict the incidence of foliar symptoms of Eutypa dieback. Information from this study could lead to an improved integrated pest management system to suppress foliar symptoms and sustain productivity of vines infected with E. lata.
