Epidemiology of Completed Suicides in Singapore for 2001 and 2002

Abstract. This study provides an analysis of 640 completed suicide cases in Singapore for the years 2001 and 2002, compared to previous years and in relation to demographic and socioeconomic factors, as well as to the characteristics of a subgroup of suicide victims with prior psychiatric illness. There was little change in the suicide pattern over the 2 years studied compared to previous years. The sex ratio was constant at 1.5. Population-adjusted ratios were 1 for Chinese, 0.5 for Malays, and > 1 for both Indians and other ethnic groups. Falling from heights ranked first in terms of method adopted for both years. A disproportionately higher number of suicides were recorded for the 25-34 and the ≥ 75-year-old age groups. A total of 47 (17.2%) in 2001 and 74 (20.2%) in 2002 of the cases had a history of prior psychiatric illness, with psychotic disorders being the most common diagnostic category. There was also a statistically significant correlation between unemployment and incidence rates. Although the overall rate of elderly suicides had gone down since the 1990s, prevention strategy should focus on the elderly as this rate is still about 3-4 times the national average.

We reviewed the findings of the Canadian Study of Health and Aging in the context of studies published between January 1986 and June 1993 that documented dementia and Alzheimer's disease prevalence. Studies were identified using a MEDLINE literature search. Additional references were selected from the bibliography of identified articles. Most reports of all types of dementia prevalence are within a narrow range for each of the age groups 65+, 75+ and 85+ years. By contrast, two recent reports on the prevalence of Alzheimer's disease have reported much higher estimates (10.3% and 15.3%) in the elderly (65+ years). A variety of threats to both validity and generalizability of the estimates are present in all studies. In community studies which employed clinical interviews most subjects were only mildly affected; the natural history of impairment of this group requires further study if the consequences of these findings are to be understood. There is important variability in the definition of the functional consequences of cognitive impairment in the elderly which affects both the diagnosis and staging of dementia.

Introduction. Silicon is a unique element in its physicochemical properties, almost ubiquitous in water supply sources but is not normalized in drinking water in the world practice of ensuring the harmlessness of water use of the population. In our country, the half-century history of the development of hygienic silicon standards in the water began with the justification of the MPC of silicon-containing reagents used in water treatment. However, over time, doubts have arisen about the suitability of manufactured silicon standards for controlling natural silicon in drinking water. Proponents of the harmlessness of natural soluble forms of silicon advocated the elimination of silicon standards in water. In contrast, researchers of the action of silicon in silicon biogeochemical provinces have constantly revealed its adverse effects on the health of the population living in these regions, confirming this with animal experiments. methods. Literature search methods on Scopus, CyberLeninka, PubMed databases: selective, analytical-synthetic, typological. the main part. The review provides information on soluble forms of silicon, their stability and bioavailability, examines the retrospective and current state of hygienic rationing of silicon in water, discusses the shortcomings of the currently existing MPC of silicon, sodium and potassium silicates in drinking water. A detailed review of studies carried out in the silicon biogeochemical provinces of Chuvashia is given, where the inhabitants of the ecological disaster zone, who consumed drinking water with a profound imbalance of macro-and microelements and a high silicon content relative to the optimum area, observed various metabolic disorders (mineral, lipid, carbohydrate, peroxide), changes in microbiocenosis of the large intestine and immune status, an increase in the incidence rate of the adult population with chronic non-infectious diseases by 2-3 times against the national average, the highest incidence rates in children of all age groups. Conclusions. The review draws attention to the need for expanded studies of the effect on the body of natural silicon in drinking water with the usual balance of trace elements to resolve issues about the standards for natural silicon at the federal and regional levels and to establish differentiated standards for silicon-containing reagents in drinking water.

SummaryBackgroundSARS-CoV-2 has been a global pandemic, but the emergence of asymptomatic patients has caused difficulties in the prevention of the epidemic. Therefore, it is significant to understand the epidemiological characteristics of asymptomatic patients with SARS-CoV-2 infection.MethodsIn this single-center, retrospective and observational study, we collected data from 167 patients with SARS-CoV-2 infection treated in Chongqing Public Health Medical Center (Chongqing, China) from January to March 2020. The epidemiological characteristics and variable of these patients were collected and analyzed.Findings82.04% of the SARS-CoV-2 infected patients had a travel history in Wuhan or a history of contact with returnees from Wuhan, showing typical characteristics of imported cases, and the proportion of severe Covid-19 patients was 13.2%, of which 59% were imported from Wuhan. For the patients who was returnees from Wuhan, 18.1% was asymptomatic patients. In different infection periods, compared with the proportion after 1/31/2020, the proportion of asymptomatic patient among SARS-CoV-2 infected patient was higher(19% VS 1.5%). In different age groups, the proportion of asymptomatic patient was the highest(28.6%) in children group under 14, next in elder group over 70 (27.3%). Compared with mild and common Covid-19 patients, the mean latency of asymptomatic was longer (11.25 days VS 8.86 days), but the hospital length of stay was shorter (14.3 days VS 16.96 days).ConclusionThe SARS-CoV-2 prevention needs to focus on the screening of asymptomatic patients in the community with a history of contact with the imported population, especially for children and the elderly population.

Abstract Between 1935 and 1974, 3598 episodes of head trauma among Olmsted County, Minnesota, residents resulted in 1097 skull fractures. Of these, 53% were simple, 16% were depressed, 12% were compound, and 19% were basilar. The age- and sex-adjusted incidence of skull fractures was 44.3 per 100,000 person-years overall, was somewhat greater in the urban than in the rural areas of Olmsted County, and was relatively stable for the final 30 years of the study. Age-specific incidence rates were highest for the very young, and simple linear fractures were the predominant type of skull fracture in this age group and among the elderly. The male:female ratio of incidence rates varied from 2.1:1 to 4.5:1 depending on fracture type. Motor vehicle accidents accounted for 38% of the skull fractures and were a particularly important cause among young males. Falls accounted for 37% of the skull fractures and were the major cause of fractures in the elderly and pediatric age groups. The results of this population-based study may be helpful in formulating recommendations for the evaluation and management of head-injured patients.

Abstract Background The prevalence of both atrial fibrillation (AF) and malignancies are increasing in the elderly, but incidences of new onset AF in different cancer subtypes are not well described.The objectives of this study were therefore to determine the incidence of AF in different cancer subtypes and to examine the association of cancer and future AF. Methods Using national databases, the Danish general population was followed from 2000 until 2012. Every individual aged > 18 years and with no history of cancer or AF prior to study start was included. Incidence rates of new onset AF were identified and incidence rate ratios (IRRs) of AF in cancer patients were calculated in an adjusted Poisson regression model. Results A total of 4,324,545 individuals were included in the study. Cancer was diagnosed in 316,040 patients. The median age of the cancer population was 67.0 year and 51.5% were females. Incidences of AF were increased in all subtypes of cancer. For overall cancer, the incidence was 17.4 per 1000 person years (PY) vs 3.7 per 1000 PY in the general population and the difference increased with age. The covariate adjusted IRR for AF in overall cancer was 1.46 (95% confidence interval (CI) 1.44–1.48). The strength of the association declined with time from cancer diagnosis (IRR0-90days = 3.41 (3.29–3.54), (IRR-180 days-1 year = 1.57 (CI 1.50–1.64) and (IRR2–5 years = 1.12 (CI 1.09–1.15). Conclusions In this nationwide cohort study we observed that all major cancer subtypes were associated with an increased incidence of AF. Further, cancer and AF might be independently associated.

SUMMARYThe reactivation of dormant alpha-human herpesvirus (αHHV) has been attributed to various causes often referred to as stressors. However, no clinical study investigating the relationship between stressors and reactivation exists in humans at this time. Herpes simplex virus type-1 (HSV-1), an important αHHV, was shown to have its gene expression and replication regulated by thyroid hormone (TH) using molecular biology approaches. Varicella zoster virus (VZV) is categorized in αHHV superfamily and shares similar homology with HSV-1. We hypothesize that a history of TH imbalance may be associated with the incidence of shingles (VZV reactivation). This current pilot study, based on a hospital medical claims database, was conducted as a retrospective case-controlled investigation to determine if a putative link between TH imbalance and incidence of shingles is present. An odds ratio of 2·95 with a χ2 value of 51·74 was calculated for the total population diagnosed with TH disruption and shingles. Further analyses indicated that African American males exhibited a much higher chance of simultaneous diagnoses. These results show that a TH imbalance history may affect VZV reactivation at different incidence rates in different races and age groups.

IntroductionSuicide risk is increased in patients with a history of psychiatric hospitalization.AimTo explore how suicide risk varies by age during psychiatric hospitalization and in the year post-discharge.MethodsThis is a population-based case-control study of all suicides (n = 20,675; 70% male) in Sweden aged ≥18 years during 1991–2003. Each suicide was individually matched to 10 population controls by age, sex, and county of residence. Discharge diagnoses of a mental disorder (except dementia and other organic disorders) in the year prior to suicide were identified by register linkage. Odds ratios (OR) were calculated by conditional logistic regression to estimate the relative risk of suicide in those with psychiatric diagnoses compared to the general population. ORs were estimated by age group (18–34 years, 35–49 years, 50–64 years, and ≥ 65 years) and timing of the suicide in relation to discharge.ResultsDuring hospitalization, the youngest age group had the greatest suicide risk elevation [OR 64 (95% CI 44-92)]. In the first month post-discharge, the oldest age group had the highest suicide risk elevation [OR 162 (95% 66–399) in the first week and OR 127 (95% 67–242) in the second to fourth weeks]. In the remaining eleven months, suicide risk elevation was lower and relatively similar in different age groups.ConclusionsDuring the year following psychiatric hospitalization, an especially high attention should be paid to the suicide risk of the elderly patients in the first month post-discharge.

The main purpose of this study was to identify specific problems and pattern of morbidities that is common in the elderly. A cross sectional study surveying the health status and needs of targeted population was conducted in selected primary health care (PHC) outpatient settings. All consenting individuals aged 60 years and above who visited the selected PHC clinics were interviewed. Information was collected using face-to-face interviews based on a structured, pre-tested questionnaire. A total of 185 people were evaluated in this study. About 75% of participants were age 60-70 years. Overall, male predominance was noted with 137 (74.1%) males and among all participant’s 80% were married. The mean BMI was 26.47±4.98 kg/m2 and mean waist circumference was 90.16±12.97 cm. The prevalence of smoking, DM, HTN, dyslipidaemia and history of IHD among participants were 7.6%, 37.8%, 49.7%, 27.6% and 8.1%, respectively and males showed a significantly higher prevalence than females in smoking and HTN (p<0.05). Hypertension was common comorbid ailment with 29.2% of stage I and 19.5% of stage II hypertension among 60-70 age groups. The majority of the participants were taking shower; using toilet, feeding and get dressed independently, 88.6%, 87.6%, 87% and 87.6% respectively. These findings provide important information on high prevalence of overweight, hypertension, diabetes, smoking and dyslipidaemia among elders. The other common morbidities were impaired vision, walking difficulty, and hearing problems. The activity of daily living (bathing dressing toileting feeding) is preserved in most of older people.

Methodological Considerations

BackgroundSeveral studies have reported a decline of up to 50% in the incidence of schizophrenia over recent decades. We aimed to measure changes in the incidence and diagnostic patterns of first-episode psychosis by comparing two Nottingham cohorts, identified in two equal periods separated by 14 years.MethodTwo prospectively ascertained cohorts of first-episode psychotic disorder were identified over the time periods 1978–80 and 1992–94. The earlier cohort was of the World Health Organization Determinants of Outcome of Severe Mental Disorder (DOSMD) ten-country study. The later cohort was obtained using similar methodology. Both groups were diagnosed using ICD-10 diagnostic criteria and age-standardised incidence rates were compared.ResultsThe standardised incidence rate for all psychotic disorders rose slightly from 2.49 to 2.87 per 10 000 population per year, but the F20 classification fell significantly by over a third (1.41 to 0.87 per 10 000 per year). The second study group (1992–1994) included a greater diversity of psychotic diagnoses compared with the first, in particular an increased proportion of acute and drug-related psychoses.ConclusionsMethodological considerations call for caution in interpreting such data, but we conclude that the significant fall in the narrowly defined diagnostic category of schizophrenia reflects a real change in the syndromal presentation of psychotic disorders.
