Psychological impact amongst patients with COVID-19 in Perak state.

INTRODUCTION: Psychological distress had been documented since the beginning of the COVID-19 outbreak in 2019. The aim of the study is to describe the psychological impact among those who were hospitalized for COVID-19 infection within 6 months after being discharged from the hospital. The psychological impact in this study is defined as depression, anxiety, and stress. MATERIALS AND METHODS: This was a cross-sectional study conducted from July 2020 till August 2021 in a regional state hospital, north of Malaysia. All patients requiring hospitalization for COVID-19 were approached within the first 2 weeks after admission to administer the Depression, Anxiety and Stress Scale - 21 Items (DASS-21) scale. Follow-up phone calls were made within 3 months of discharged to enquire about the DASS-21 items as well as the Impact of Event Scale-Revised (IES-R) scale items. Participants above the age of 18 and technology savvy to answer an online questionnaire were recruited for the study. We excluded participants with a known history of psychotic disorder from the study. We utilised the DASS-21 to screen for depression, anxiety, and stress, as well as the IES-R to identify symptoms of post-traumatic stress disorder. Participants could answer the questionnaires in either English or Bahasa Malaysia. For comparison of two categorical data, a chi-square was applied. A univariate analysis was first conducted and all variables with a p ≤0.3 was then entered into the multivariate analysis for the final output. Other than the univariate analysis, all other p values <0.05 were considered to be statistically significant. All data collected were tabulated and analysed in the SPSS v21.0 system. RESULTS: A total of 306 out of 696 COVID-19 patients responded. The mean age for the participants was 31.69 (SD:11.19) years old. From the total, 54.2% were ladies, 78.8% were Malay, 50.7% were unmarried, 55.2% had higher education, and 67.6% were employed at the time of the survey. We found 20.5% of the participants were depressed, 38.9% had moderate anxiety, and 17.3% were stressed. From the total, 31.7% of the participants were deemed to have had some symptoms of post-traumatic stress disorder (PTSD) ranging from mild to severe. From the final multivariate analysis, it was found that depression (p=0.02) had a 2.78 times likeliness of having PTSD, anxiety (p<0.001) had a 3.35 times likeliness of having PTSD and stressed patients (p=0.02) 2.86 times likeliness of having PTSD when compared to those without PTSD. CONCLUSION: Patients reported to suffer from symptoms of PTSD and might benefit from psychological interventions to mitigate the impact in the long run.

Whole-grain intake and its inverse relationships with fatty acids intake among multiethnic Malaysian schoolchildren.

INTRODUCTION: Little is known about the relationship of whole-grain intake with dietary fatty acids intake. The present study aimed to assess the whole-grain intake and its relationships with dietary fatty acids intake among multiethnic schoolchildren in Kuala Lumpur, Malaysia. METHODS: This cross-sectional study was conducted among 392 schoolchildren aged 9-11 years, cluster sampled from five randomly selected schools in Kuala Lumpur. Whole-grain and fatty acids intakes were assessed by 3-day, 24-h diet recalls. All whole-grain foods were considered irrespective of the amount of whole grain they contained. RESULTS: In total, 55.6% (n = 218) were whole-grain consumers. Mean (SD) daily intake of whole grain in the total sample was 5.13 (9.75) g day-1 . In the whole-grain consumer's only sample, mean (SD) intakes reached 9.23 (11.55) g day-1 . Significant inverse associations were found between whole-grain intake and saturated fatty acid (SAFA) intake (r = -0.357; P < 0.001), monosaturated fatty acid (MUFA) (r = -0.373; P < 0.001) and polyunsaturated fatty acid (PUFA) (r = -0.307; P < 0.001) intake. Furthermore, whole-grain intake was a significant predictor of SAFA (ß = -0.077; P = 0.004), MUFA (ß = -0.112; P = <0.001) and PUFA (ß = -0.202; P = <0.001) intakes, after controlling for sex, age and ethnicity. CONCLUSIONS: Whole-grain intake in Malaysia was well below recommendations. Schoolchildren who consumed higher whole grain tend to reduce fat intake; however, it would also reduce the SAFA, MUFA and PUFA intakes. Future collaboration may be conducted between industry, government and universities to promote unsaturated fatty acids-rich foods and whole-grain food, although not to promote processed whole-grain foods with a high sugar and salt content.

Improvement over time in outcomes for patients undergoing endoscopic therapy for Barrett's oesophagus-related neoplasia: 6-year experience from the first 500 patients treated in the UK patient registry.

BACKGROUND: Barrett's oesophagus (BE) is a pre-malignant condition leading to oesophageal adenocarcinoma (OAC). Treatment of neoplasia at an early stage is desirable. Combined endoscopic mucosal resection (EMR) followed by radiofrequency ablation (RFA) is an alternative to surgery for patients with BE-related neoplasia. METHODS: We examined prospective data from the UK registry of patients undergoing RFA/EMR for BE-related neoplasia from 2008 to 2013. Before RFA, visible lesions were removed by EMR. Thereafter, patients had RFA 3-monthly until all BE was ablated or cancer developed (endpoints). End of treatment biopsies were recommended at around 12 months from first RFA treatment or when endpoints were reached. Outcomes for clearance of dysplasia (CR-D) and BE (CR-IM) at end of treatment were assessed over two time periods (2008-2010 and 2011-2013). Durability of successful treatment and progression to OAC were also evaluated. RESULTS: 508 patients have completed treatment. CR-D and CR-IM improved significantly between the former and later time periods, from 77% and 56% to 92% and 83%, respectively (p<0.0001). EMR for visible lesions prior to RFA increased from 48% to 60% (p=0.013). Rescue EMR after RFA decreased from 13% to 2% (p<0.0001). Progression to OAC at 12 months is not significantly different (3.6% vs 2.1%, p=0.51). CONCLUSIONS: Clinical outcomes for BE neoplasia have improved significantly over the past 6 years with improved lesion recognition and aggressive resection of visible lesions before RFA. Despite advances in technique, the rate of cancer progression remains 2-4% at 1 year in these high-risk patients. TRIAL REGISTRATION NUMBER: ISRCTN93069556.

Influence of oxyhydrogen gas retrofit into two-stroke engine on emissions and exhaust gas temperature variations.

The generation of power and fuel sustainability that contributes to a cleaner output of exhaust gases is one of the most important objectives the world seeks. In this paper, oxyhydrogen gas is used to retrofit into a two-stroke engine. The water was electrolysed and generated a mixture of oxygen (O2) and hydrogen (H2) or known as oxyhydrogen (HHO) gas via an electrolytic dry cell generator. The HHO was retrofitted experimentally to investigate the engine emissions and exhaust gas temperature from a 1.5 kW gasoline engine. The engine was tested with different power ratings (84-720 W) to investigate the performance and emissions of the engine using gasoline followed by the addition of HHO. The emissions of CO and NOx were measured with different amounts of HHO added. The exhaust temperature was calculated as one of the variables to be considered in relation to pollution. The air-fuel ratios are varied from 12 to 20% in the experiment. The most appropriate air-fuel ratio needed to start the generator with the most environmentally friendly gas emission was analysed. The results showed that the addition of HHO to the engine is successful in reducing fuel consumption up to 8.9%. A higher percentage of HHO added also has improved the emissions and reduced exhaust gas temperature. In this study, the highest quantity of HHO added at 0.15% of the volume fraction reduced CO gas emission by up to 9.41%, NOx gas up to 4.31%, and exhaust gas temperature by up to 2.02%. Generally, adding oxyhydrogen gas has significantly reduced the emissions, and exhaust temperature and provided an eco-friendly environment.

Reliability of acute illness dihydrorhodamine-123 testing for chronic granulomatous disease.

BACKGROUND: Dihydrorhodamine (DHR) flow cytometric analysis is used to evaluate granulocyte oxidative bursts and is the test of choice for the diagnosis of chronic granulomatous disease (CGD). We present the clinical and DHR test profiles of five subjects assessed during and after acute illness. METHODS: This was a retrospective report of the findings of five out of a total of one hundred and seventeen patients, whose blood was sent to the laboratory for dihydrorhodamine-123 flow cytometry testing between January 2005 and December 2010. Using whole blood technique and stimulation using phorbol myristate acetate, the results of DHR were expressed as stimulation index and coefficient of variation of histograms of stimulated cells and compared with healthy controls. DHR tests were repeated when the patients had recovered and were clinically well. RESULTS: These five patients showed abnormal DHR test results during their acute illness, with a stimulation index (SI) lower (p = 0.009) and coefficient of variation (CV) higher (p = 0.009) than controls. The DHR profiles repeated when patients had recovered showed normalization of tests with no significant difference for SI (p = 0.602) and CV (p = 0.917) compared to controls. Wilcoxon Signed Rank tests showed a significant improvement in SI (p = 0.043) and CV (p = 0.043) upon recovery. On follow up, all five patients were well, with no further severe or atypical infections. CONCLUSIONS: DHR may be transiently abnormal during acute illness, and may therefore not be reliable when assessed during an acute illness. If these subjects had CGD, it would be of a hypomorphic variant that has not previously been described.

The impact of neuropsychiatric symptoms on caregiver distress and quality of life in persons with dementia in an Asian tertiary hospital memory clinic.

BACKGROUND: This study aims to determine the prevalence, profile, and severity of neuropsychiatric symptoms (NPS) across the dementia continuum and their relative impact on caregiver distress and quality of life (QoL) in persons with dementia (PWD). METHOD: Six hundred and sixty-seven PWD and their family caregivers presented to a memory clinic in a tertiary hospital across a 60-month period. Clinicians determined the dementia diagnosis and severity using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition and the Clinical Dementia Rating scale, respectively. The Neuropsychiatric Inventory Questionnaire was administered to assess NPS in PWD and the corresponding distress experienced by the caregiver. QoL for PWD (PWD-QoL) was assessed by the Quality of Life-Alzheimer's Disease scale. RESULTS: Ninety-six percent of PWD presented with at least one NPS, 18% experiencing mild, 31% moderate, and 47% severe symptoms, respectively. While agitation (63.1%), apathy (61.8%), depression (55.5%), and irritability (55.5%) were the most common NPS; disinhibition (35.2%), hallucination (25.5%), and elation (14.2%) were the least common. NPS increased generally but differentially as dementia progressed and significantly predicted caregiver distress (ηp 2 = 0.732, p < 0.0001) and PWD-QoL (ηp 2 = 0.066, p < 0.0001). Factor analysis revealed two NPS clusters, disruptive and affective; the former exerting greater impact on caregiver distress and the latter on PWD-QoL. CONCLUSION: The results show a high prevalence of NPS which increase caregiver distress and negatively impact PWD-QoL. The differential profile of NPS across the dementia stages warrants stage-specific interventions and due consideration in resource planning and service design for PWD and their caregivers.

Tissue factor expression in the metaplasia-adenoma-carcinoma sequence of gastric cancer in a European population.

BACKGROUND: Tissue factor (TF), which has a role in normal tissue haemostasis, was reported to be aberrantly expressed, associated with higher microvascular density and a poor prognosis in intestinal-type gastric adenocarcinoma in the Japanese population. This is the first study to look at the relationship of TF and the metaplasia-adenoma-carcinoma sequence (MACS) of gastric cancer in a European population. METHODS: The expression of TF was examined immunohistochemically in 191 gastric tissue samples: (13: normal; 18: intestinal metaplasia; 160: gastric adenocarcinoma) from the European population. RESULTS: TF was not expressed in normal gastric mucosal cells. A strong intensity of staining was found in intestinal metaplasia cells but in 2 of 18 samples. TF expression increased with advancing stage of gastric cancer (P<0.0001, Jonckheere's test for ordered medians). Stage 3-4 gastric cancers preferentially expressed TF (34%, P=0.04). In comparison with the Japanese study, TF was not expressed at a higher level in intestinal vs diffuse-type gastric cancers and expression had 'no prognostic' significance. CONCLUSION: TF may be involved in tumour progression along the MACS of gastric cancer in the European population and is shown to start in precancerous lesions. However, clinical features may differ due to differences in biological features in the two populations, as reflected by differences in TF expression profile.

The FOXM1-PLK1 axis is commonly upregulated in oesophageal adenocarcinoma.

BACKGROUND: The transcription factor FOXM1 is an important regulator of the cell cycle through controlling periodic gene expression during the G2 and M phases. One key target for FOXM1 is the gene encoding the protein kinase PLK1 and PLK1 itself acts in a positive feedback loop to phosphorylate and activate FOXM1. Both FOXM1 and PLK1 have been shown to be overexpressed in a variety of different tumour types. METHODS: We have used a combination of RT-PCR, western blotting, tissue microarrays and metadata analysis of microarray data to study whether the FOXM1-PLK1 regulatory axis is upregulated and operational in oesophageal adenocarcinoma. RESULTS: FOXM1 and PLK1 are expressed in oesophageal adenocarcinoma-derived cell lines and demonstrate cross-regulatory interactions. Importantly, we also demonstrate the concomitant overexpression of FOXM1 and PLK1 in a large proportion of oesophageal adenocarcinoma samples. This co-association was extended to the additional FOXM1 target genes CCNB1, AURKB and CKS1. In a cohort of patients who subsequently underwent surgery, the expression of several FOXM1 target genes was prognostic for overall survival. CONCLUSIONS: FOXM1 and its target gene PLK1 are commonly overexpressed in oesophageal adenocarcinomas and this association can be extended to other FOXM1 target genes, providing potentially important biomarkers for predicting post-surgery disease survival.

PEA3/ETV4-related transcription factors coupled with active ERK signalling are associated with poor prognosis in gastric adenocarcinoma.

BACKGROUND: Transcription factors often play important roles in tumourigenesis. Members of the PEA3 subfamily of ETS-domain transcription factors fulfil such a role and have been associated with tumour metastasis in several different cancers. Moreover, the activity of the PEA3 subfamily transcription factors is potentiated by Ras-ERK pathway signalling, which is itself often deregulated in tumour cells. METHODS: Immunohistochemical patterns of PEA3 expression and active ERK signalling were analysed and mRNA expression levels of PEA3, ER81, MMP-1 and MMP-7 were determined in gastric adenocarcinoma samples. RESULTS: Here, we have studied the expression of the PEA3 subfamily members PEA3/ETV4 and ER81/ETV1 in gastric adenocarcinomas. PEA3 is upregulated at the protein level in gastric adenocarcinomas and both PEA3/ETV4 and ER81/ETV1 are upregulated at the mRNA level in gastric adenocarcinoma tissues. This increased expression correlates with the expression of a target gene associated with metastasis, MMP-1. Enhanced ERK signalling is also more prevalent in late-stage gastric adenocarcinomas, and the co-association of ERK signalling and PEA3 expression also occurs in late-stage gastric adenocarcinomas. Furthermore, the co-association of ERK signalling and PEA3 expression correlates with decreased survival rates. CONCLUSIONS: This study shows that members of the PEA3 subfamily of transcription factors are upregulated in gastric adenocarcinomas and that the simultaneous upregulation of PEA3 expression and ERK pathway signalling is indicative of late-stage disease and a poor survival prognosis.

Effects of preslaughter shackling on postmortem glycolysis, meat quality, changes of water distribution, and protein structures of broiler breast meat.

The objective of this study was to investigate the effects of preslaughter shackling on stress, postmortem glycolysis, meat quality, water distribution, and protein structures of pectoralis majors. Before slaughter, Arbor Acres broilers (n = 105, 42 days old, 2.0 to 2.5 kg) were randomly categorized into 3 treatment groups: (I) control group without shackling (NS); (II) 2.5 min shackling (SS); (III) 4.5 min shackling (LS). Each treatment group consisted of 5 replicates with 7 broilers each. Results indicated that preslaughter shackling increased (P < 0.05) plasma corticosterone and adrenocorticotropic hormone concentrations in comparison with the control group. Antemortem shackling increased (P < 0.05) activity of glycogen phosphorylase and phosphofructokinase-1 (PFK-1) accompanying with rapid glycolysis and pH decline at early postmortem. LS treatment led to myosin denaturation, decreased (P < 0.05) α-helix content, and increased (P < 0.05) ß-sheet structures proportion in the myofibrillar proteins. Furthermore, meat from LS treatment had higher (P < 0.05) lightness, redness, and poorer water-holding capacity. These results indicated that the longer shackling duration (4.5 min) increased stress and the rate of glycolysis, causing myosin denaturation and changes of the secondary structure in the myofibrillar proteins, which aggravated the deterioration of meat quality.

EndoCinch treatment for gastro-oesophageal reflux disease.

Gastro-oesophageal reflux disease (GORD) is a common disorder which significantly impairs the quality of life. Recently an EndoCinch system has been described, with an approach to the treatment of GORD that would obviate the need for long-term proton pump inhibitors and the cost and potential risk of laparoscopic Nissen fundoplication. We set outto evaluate the status of this new technique for the management of GORD. We review the literatures (publications and abstracts) regarding safety, efficacy, and durability of this new antireflux procedure. On the whole, this new antireflux technique produced significant improvement in GORD symptomatology and quality of life and reduced the use of antireflux medication. However, it failed to normalize acid reflux, long-term durability data are lacking, and some serious side effects have been reported. In conclusion, EndoCinch has the potential to treat patients with this common ailment. However, further studies are necessary to determine what modifications to this antireflux technique are required in order to produce the maximum clinical benefit.

Functional decline of the elderly in a nursing home.

INTRODUCTION: This study aims to determine if risk factors present on admission to the nursing home could be predictive of later functional decline and to determine the causes of decline. METHODS: This is a retrospective case-control study conducted in 2000 at a voluntary welfare nursing home. Functional decline was defined as deterioration in two or more of the five activities of daily living (ADLs), namely: mobility, toileting, bathing, dressing and feeding, from the time of admission to the study period. Potential risk factors for decline studied were: age, sex, marital status, number of medical diagnoses and medications, types of medical diagnoses, and the presence of dementia on admission to the home. Causes of decline were categorised as (A) Development of new illness, (B) Progression of chronic illness, or (C) Both of the above. RESULTS: 36 out of 103 residents had functional decline. On analysis, univariate and multivariable logistic regression models, adjusted for length of stay, yielded the same significant risk factors for decline, namely: age (p-value is 0.02) and dementia (p-value is 0.04). Majority of decline (78 percent) was due to progression of chronic illnesses, most commonly dementia (15 out of 36), eight percent were due to acute illness (stroke), and 14 percent were due to both. In January 2003, 18 out of the 36 residents who declined had died. CONCLUSIONS: Functional decline is common in the nursing home. More attention should be paid to the older residents and those with dementia, right from the point of admission.

Neonatal meliodosis: very rare but be aware.

Meliodosis is an infectious disease encountered mainly in tropics. It is not an uncommon problem in Malaysia especially in areas with agricultural activities. Although it can occur in all age groups, there have been few reported cases in children. Men are more commonly affected than women due to outdoor activities. Neonatal cases have been reported in Hawaii and Thailand. These infants presented with neonatal sepsis or meningitis. The mode of transmission to these infants has not been elucidated. This is the report of such a case first reported in Hospital Tengku Ampun Afzan, Kuantan.

Randomized comparison of unfractionated heparin with corticosteroids in severe active inflammatory bowel disease.

BACKGROUND: Heparin therapy may be effective in steroid resistant inflammatory bowel disease. AIM: A randomized pilot study, to compare unfractionated heparin as a first-line therapy with corticosteroids in colonic inflammatory bowel disease. METHODS: Twenty patients with severe inflammatory bowel disease (ulcerative colitis, n=17; Crohn's colitis, n=3) were randomized to either intravenous heparin for 5 days, followed by subcutaneous heparin for 5 weeks (n=8), or high-dose intravenous hydrocortisone for 5 days followed by oral prednisolone 40 mg daily, reducing by 5 mg per day each week (n=12). After 5 days, non-responders in each treatment group were commenced on combination therapy. Response to therapy was monitored by: clinical disease activity (ulcerative colitis: Truelove and Witt Index; Crohn's colitis: Harvey and Bradshaw Index), stool frequency, serum C-reactive protein and alpha1 acid glycoprotein, endoscopic and histopathological grading. RESULTS: The response rates were similar in both treatment groups: clinical activity index (heparin vs. steroid; 75% vs. 67%; P=0.23), stool frequency (75% vs. 67%; P=0.61), endoscopic (75% vs. 67%; P=0.4) and histopathological grading (63% vs. 50%; P=0.67). Both treatments were well-tolerated with no serious adverse events. CONCLUSION: Heparin as a first line therapy is as effective as corticosteroids in the treatment of colonic inflammatory bowel disease. Large multicentre randomized comparative studies are required to determine the role of heparin in the management of inflammatory bowel disease.

Predictive factors of post-discharge mortality in the hospitalised elderly.

AIM: To study the death rate of noninstitutionalised elderly after discharge from hospital, describe the causes of death and identify predictive factors of mortality. METHODS: Vital status and cause of death of patients was ascertained by linkage to the death registry I year post discharge. Age, sex, race, marital status, housing and class of ward (to reflect socioeconomic status), presence of carer, Elderly Cognitive Assessment Questionnaire (ECAQ) score, Barthel score, presence of depression, number of chronic illnesses and length of stay in the hospital were studied as potential predictive factors for mortality using Cox proportional hazard regression models. RESULTS: Death occurred in 38 out of 113 patients. The commonest causes of death were malignancy (18%) and cerebrovascular disease (18%). Barthel score and length of stay were independent significant predictive factors of mortality. Elderly with low ECAQ score, with carers and from C class wards also had higher mortality although these results were not statistically significant. CONCLUSION: Post-discharge mortality is high in the elderly. We recommend that further studies be done to determine if amelioration of these predictive factors would lead to decreased mortality or improvement of quality of life.

Profile of a homosexual in Singapore.

A study was done on 40 homosexual subjects and 47 controls between the ages of 18-19 years, matched for race and age. There was no significant difference in the educational level, and family background of the 2 groups. But homosexuals had a significantly more unhappy childhood than the controls, were more often reprimanded than physically punished and were often teased by their classmates and called names. They were not overprotected or infantilized by their parents and there was no overclose relationship with their mothers. The majority mixed with effeminate boys, admired a senior person in school and about a third had a physical relationship with this person. Almost half had been molested when they were young. Less than a fifth had girlfriends. About three-quarters knew of AIDS and of these less than a fifth felt they would give up their sexual practices because of fear of AIDS. The main problems faced by the subjects were confusion about their identity, their desire to find the right partner, relationship problems and difficulties in controlling their impulses.

Adjusting to military life--servicemen with problems coping and their outcomes.

A small proportion of servicemen enlisting for compulsory National Service in Singapore experience problems adjusting to military life. This paper aims to profile the servicemen who experience such problems. There is a paucity of literature addressing this issue internationally and none published locally. Servicemen who were referred to the Psychological Medicine Branch of the Singapore Armed Forces within six months of enlistment were retrospectively studied. In the work year July 1995 to June 1996, 77 cases were seen. The main classes of diagnoses were stress-related disorders, anxiety, mood and psychotic disorders. The main stressor was problems adapting to the military environment. There were 10 cases of parasuicide, significantly less than US Army statistics. At Operationally Ready Date, 20.7% were able to hold a combat vocation, similar to the US Army situation. This paper hopes to document the local figures and act as a reference for evaluating future therapies and policies.

Who are the residents of a nursing home in Singapore?

AIM OF STUDY: To describe the residents of a nursing home for the elderly in terms of their socio-demographic profile, mental and physical attributes, functional abilities and existing medical problems. METHOD: A random sample of 120 subjects was obtained from a total of 350 residents in a voluntary welfare nursing home. Two subjects were excluded as they did not satisfy inclusion criteria (age > or = 60 years). The subjects' biodata, social background, medical problems and functional status at the time of admission were obtained by a review of the case records. Each of the subjects was examined with attention to their general condition, hearing and vision, presence of postural hypotension, cognition and ability to perform basic activities of daily living (ADL). RESULTS: Results were available for 106 out of the 118 subjects as the rest were either discharged in the course of the study or had died. Single (36%), widowed (41%), female (71%) and age > or = 75 years (73%) consisted the majority. Most subjects (43%) were admitted because of both medical and social factors. Twenty-two percent appeared undernourished and of those who could be assessed, 14% had postural hypotension, 18% were hearing impaired and 53% had visual impairment. Fifty-two per cent suffered from mental problems while 46% and 40% had been diagnosed with hypertension and stroke respectively. Forty-eight percent had probable cognitive impairment (according to ECAQ scores) and 41% were very severely disabled (according to Barthel Index). Fifty-five percent were dependent in bathing, 50% dependent in dressing, 50% incontinent of urine (and requiring diapers), 48% were non-ambulant and 21% dependent in feeding. CONCLUSION: With a significant proportion of the population requiring nursing home care in the future, a closer review of the situation is needed. This study has identified malnutrition, urinary incontinence, falls, functional decline and impaired vision/hearing as issues that deserve greater attention and, where necessary, intervention. Whether implementing recognised effective interventions will truly benefit our nursing home residents would warrant more local studies.

Parasuicide in male conscripts: a Singapore experience.

This is a retrospective study of 156 cases of parasuicide in a homogenous population of male conscripts in the Singapore Armed Forces. The rate of parasuicide was 12.5 per 100,000 soldiers at risk. Suicide attempters were from the lower rank and one-third were undergoing basic military training at the time of their attempts. Drug ingestion was the commonest method and this was followed by jumping from a height, a method unique to the Singapore experience. Most of the conscripts gave no prior warning and appeared to have no strong desire to kill themselves. Interpersonal problems was the predominant reason given for their suicide attempts.
