    Chronic kidney disease is an emerging problem in the majority Muslim countries. Despite the uncertainties of the risks involved, some Muslim patients undergoing chronic haemodialysis choose to observe intermittent fasting during the month of Ramadan. This study aims to investigate the effect of Ramadan fasting in haemodialysis patients residing in a tropical climate country.

    Previous nationally representative studies have reported prevalence of DSM-IV generalized anxiety disorder (GAD). However, subthreshold and threshold GAD expressions remain poorly understood. The current study examined the prevalence, correlates and co-morbidity of a broader diagnosis of GAD in Singapore. The Singapore Mental Health Study (SMHS) was an epidemiological survey conducted in the population (N=6616) aged 18 years and older. The Composite International Diagnostic Interview version 3.0 (CIDI 3.0) was used to establish mental disorder diagnoses. The lifetime prevalence for subthreshold GAD (2.1%) and threshold GAD (1.5%) in the current sample was found to be lower than in Western populations. Younger age group, Indian ethnicity, previously married, chronic physical conditions, and being unemployed were associated with higher odds of having more severe expression of generalized anxiety. The relatively lower prevalence rate of subthreshold GAD expression suggests possible cultural interferences in the reporting and manifestation of anxiety symptomatology. Despite the low prevalence, significant impacts on functioning and comorbidity among subthreshold generalized anxiety cases indicate the importance of early treatment to ensure a better prognosis.

    Pulmonary alveolar microlithiasis (PAM) is a rare chronic disease with paucity of symptoms in contrast to the imaging findings. We present a case of a 24-year-old Malay man having an incidental abnormal pre-employment chest radiograph of dense micronodular opacities giving the classical "sandstorm" appearance. High-resolution computed tomography of the lungs showed microcalcifications with subpleural cystic changes. Open lung biopsy showed calcospherites within the alveolar spaces. The radiological and histopathological findings were characteristic of PAM.

    Chronic intestinal pseudo-obstruction (CIPO) is a rare clinical syndrome of ineffective intestinal motility characterised by clinical and radiological evidence of intestinal obstruction with no identifiable mechanical lesion. CIPO can either be idiopathic or secondary to a systemic disease, like systemic lupus erythematosus (SLE). Fewer than 30 cases of CIPO secondary to SLE have been reported so far. Here we describe a case of SLE with the initial presentation of CIPO. In SLE-related CIPO, treatment includes a combination of high-dose intravenous corticosteroids, immunosuppressants and supportive care. With awareness of this condition, unnecessary surgical intervention and repeated invasive procedures could be avoided. Early initiation of treatment would avoid complications and bring about resolution of symptoms.

    Trichuris Dysentery Syndrome (TDS) is a severe persistent trichuriasis associated with heavy worm build-up in the colon that continues to be neglected and underestimated in endemic countries. Trichuriasis is most prevalent in children in tropical countries, and that increases the risk of TDS. We reported a series of four preschool children of both genders chronically having TDS over a period ranging from several months to years presenting with anaemia. The hemoglobin levels ranged from 4.6 to 9.1 g/dl on first admissions. Despite treatment, the cases were reported to have failure to thrive with persistent anaemia. It was concluded that TDS should be considered in endemic areas among children presenting with chronic bloody diarrhea and anaemia.

    OBJECTIVE: This study examines the International Classification of Functioning, Disability, and Health model (ICF) using a data set of 2,563 community-dwelling elderly with disease-independent measures of mobility, physical activity, and social networking, to represent ICF constructs.

    METHOD: The relationship between chronic disease and disability (independent and dependent variables) was examined using logistic regression. To demonstrate variability in activity performance with functional impairment, graphing was used. The relationship between functional impairment, activity performance, and social participation was examined graphically and using ANOVA. The impact of cognitive deficits was quantified through stratifying by dementia.

    RESULTS: Disability is strongly related to chronic disease (Wald 25.5, p < .001), functional impairment with activity performance (F = 34.2, p < .001), and social participation (F= 43.6, p < .001). With good function, there is considerable variability in activity performance (inter-quartile range [IQR] = 2.00), but diminishes with high impairment (IQR = 0.00) especially with cognitive deficits.

    DISCUSSION: Environment modification benefits those with moderate functional impairment, but not with higher grades of functional loss.

    Noncommunicable diseases (NCDs; mainly cancer, cardiovascular diseases, diabetes, and chronic respiratory diseases) are now responsible for more than 35 million deaths per annum in the world; more than 80% of these deaths occur in low- and middle-income countries. Dramatic worldwide changes in lifestyle and in the prevalence and incidence of major chronic diseases lends credence to the causative role of modifiable risk factors. For the elucidation of modifiable risk factors, large-scale prospective cohort studies with biobanks often combined in consortia are of paramount importance. Associations between selected risk factors and development of NCDs will be reviewed. In addition to the contribution of treatment, even larger proportions of NCDs can be prevented had risk factors been reduced to the optimum levels or eliminated. Individual-based approaches should be complemented by administrative regulations.

    BACKGROUND: Central and bridge nodes can drive significant overall improvements within their respective networks. We aimed to identify them in 16 prevalent chronic diseases during the coronavirus disease 2019 (COVID-19) pandemic to guide effective intervention strategies and appropriate resource allocation for most significant holistic lifestyle and health improvements.

    METHODS: We surveyed 16 512 adults from July 2020 to August 2021 in 30 territories. Participants self-reported their medical histories and the perceived impact of COVID-19 on 18 lifestyle factors and 13 health outcomes. For each disease subgroup, we generated lifestyle, health outcome, and bridge networks. Variables with the highest centrality indices in each were identified central or bridge. We validated these networks using nonparametric and case-dropping subset bootstrapping and confirmed central and bridge variables' significantly higher indices through a centrality difference test.

    FINDINGS: Among the 48 networks, 44 were validated (all correlation-stability coefficients >0.25). Six central lifestyle factors were identified: less consumption of snacks (for the chronic disease: anxiety), less sugary drinks (cancer, gastric ulcer, hypertension, insomnia, and pre-diabetes), less smoking tobacco (chronic obstructive pulmonary disease), frequency of exercise (depression and fatty liver disease), duration of exercise (irritable bowel syndrome), and overall amount of exercise (autoimmune disease, diabetes, eczema, heart attack, and high cholesterol). Two central health outcomes emerged: less emotional distress (chronic obstructive pulmonary disease, eczema, fatty liver disease, gastric ulcer, heart attack, high cholesterol, hypertension, insomnia, and pre-diabetes) and quality of life (anxiety, autoimmune disease, cancer, depression, diabetes, and irritable bowel syndrome). Four bridge lifestyles were identified: consumption of fruits and vegetables (diabetes, high cholesterol, hypertension, and insomnia), less duration of sitting (eczema, fatty liver disease, and heart attack), frequency of exercise (autoimmune disease, depression, and heart attack), and overall amount of exercise (anxiety, gastric ulcer, and insomnia). The centrality difference test showed the central and bridge variables had significantly higher centrality indices than others in their networks (P chronic diseases during the COVID-19 pandemic, enhanced interventions and optimised resource allocation toward central lifestyle factors, health outcomes, and bridge lifestyles are paramount. The key variables shared across chronic diseases emphasise the importance of coordinated intervention strategies.

    Granular myringitis is a chronic inflammatory condition of the tympanic membrane that does not involve the middle ear. Various treatment modalities have been proposed for the treatment of granular myringitis, but there is no standard treatment regime. A 60-year-old woman had left persistent ear discharge for 4 months. Examination revealed diffuse granulation tissue, forming a pseudomembrane at the medial aspect of the ear canal and obstructing the tympanic membrane. An audiogram revealed mild-to-moderate left-sided conductive hearing loss. She was treated with multiple courses of ear drop antibiotics but had no improvement. The decision for surgical intervention was driven by the presence of a grade IV medial meatal stenosis, the potential risks associated with prolonged medical management, the distressing impact on the patient's life, and a shared decision-making process. A combined transcanal and postauricular endoscopic approach whereby excision of the granulation tissue, canalplasty, and myringoplasty were performed. She exhibited complete symptom resolution and reported an improved quality of life. This approach yielded successful symptom resolution, highlighting its potential in managing refractory chronic granular myringitis. We aimed to carefully weigh the risks of surgery against its potential benefits in a refractory chronic case, acknowledging the inherent risks and disadvantages of surgical interventions. Further studies are warranted to evaluate the long-term outcomes and benefits of this approach.

    BACKGROUND: Large epidemiologic studies have reported the premature onset of age-related conditions, such as ischemic heart disease and diabetes mellitus, in childhood cancer survivors, decades earlier than in their peers. The authors investigated whether young adult survivors of childhood acute lymphoblastic leukemia (ALL) have a biologic phenotype of cellular ageing and chronic inflammation.

    METHODS: Plasma inflammatory cytokines were measured using a cytometric bead array in 87 asymptomatic young adult survivors of childhood ALL (median age, 25 years; age range, 18-35 years) who attended annual follow-up clinic and compared with healthy, age-matched and sex-matched controls. Leukocyte telomere length (LTL) was measured using Southern blot analysis.

    RESULTS: Survivors had significant elevation of plasma interleukin-2 (IL-2), IL-10, IL-17a, and high-sensitivity C-reactive protein levels (all P 0.8 mg/dL) was related to increased odds of having metabolic syndrome (odds ratio, 7.256; 95% confidence interval, 1.501-35.074). Survivors also had significantly shorter LTL compared with controls (median, 9866 vs 10,392 base pairs; P = .021). Compared with published data, LTL in survivors was similar to that in healthy individuals aged 20 years older. Survivors who received cranial irradiation had shorter LTL compared with those who had not (P = .013).

    CONCLUSIONS: Asymptomatic young adult survivors of childhood ALL demonstrate a biologic profile of chronic inflammation and telomere attrition, consistent with an early onset of cellular processes that drive accelerated aging. These processes may explain the premature development of age-related chronic conditions in childhood cancer survivors. Understanding their molecular basis may facilitate targeted interventions to disrupt the accelerated aging process and its long-term impact on overall health.

    The management of chronic nonhealing ulcers pose a great challenge because they are associated with morbidity and increased costs. This report presents the observations of standard management along with application of modified collagen with glycerin (MCG) in the periwound area for management of nonhealing wounds. This observational report included 50 patients (33 male, 17 female) aged 24 to 94 years having nonhealing wounds. All wounds were treated using standard treatment protocols (TIME concept), whereas the periwound severity was assessed using the Harikrishna Periwound Skin Classification (HPSC). All patients received once-daily application of MCG lotion directly in the periwound areas and compression bandaging until there was complete wound healing. Patient compliance was ensured by regular follow-up and counseling. All diabetic patients were counseled to ensure glycemic control during the entire follow-up period. The criteria used for wound healing were based on clinical observation, and proper epithelialization of the wound was the end point. The median age of the wounds was 12.0 weeks (95% CI = 8.00 - 58.08). Majority of the non-healing wounds were diabetic foot ulcers with age of wound between 4 weeks to 15 years. The median time to complete wound healing was 12.71 (95% CI = 10.00-16.67) weeks. Standard treatment protocol of TIME principle with periwound area assessment based on HPSC 2015 and treatment accordingly with topical application of MCG along with additional measures has shown complete healing of nonhealing wounds. However, further large-scale comparative studies are needed to substantiate these effects on a larger population.

    Background Eosinophilic chronic rhinosinusitis (eCRS) is linked with skewed T-helper 2 or immunoglobulin E (IgE)-mediated allergic responses, with differing diagnosis, prognosis, and management to non-eCRS. Objective The association between biomarkers and eCRS was investigated to assess the predictors of eCRS. Methods A cross-sectional study of adult patients with chronic rhinosinusitis (CRS) undergoing endoscopic sinus surgery was conducted. eCRS was defined by histopathological assessment showing >10 eosinophils/high-power field on sinus mucosal biopsy. Blood tests were performed preoperatively and assessed for a full blood count including eosinophils and a white cell count (WCC) as well as biochemical markers of inflammation and atopy including Immunoglobulin E (IgE), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and ImmunoCAP testing for serum-specific IgE. Comparisons between eCRS and non-eCRS patients were performed. Results 345 patients (48.1% female, age 48.72 ± 15.06 years) were recruited, with 206 (59.7%) identified as eCRS, 41% with asthma and 47% CRS with nasal polyps. eCRS patients were more likely to have asthma ( P 0.24 × 109/L), eosinophil ratio (>4.27% of total WCC), and lower ESR when compared with non-eCRS.

    BACKGROUND: Burkholderia pseudomallei is the causative agent of melioidosis, which is a potentially life threatening disease endemic in Southeast Asian countries. In Malaysia, cystic fibrosis (CF) is an uncommon condition. The association between CF and B.pseudomallei infections has been reported previously. However, this is the first case report of a pediatric melioidosis relapse and co-infection with other Gram-negative bacteria in Malaysia.

    CASE PRESENTATION: A 14-year-old Chinese Malaysian boy presented with a history of recurrent pneumonia, poor growth and steatorrhoea since childhood, and was diagnosed with CF. B. pseudomallei was cultured from his sputum during three different admissions between 2013 and 2016. However, the patient succumbed to end stage of respiratory failure in 2017 despite antibiotics treatment against B.pseudomallei. The isolates were compared using multilocus-sequence typing and repetitive-element polymerase chain reaction (PCR), and confirmed that two of the isolates were of same sequence type, which may indicate relapse.

    CONCLUSIONS: CF patients should be aware of melioidosis in endemic regions, as it is an emerging infectious disease, especially when persistent or recurrent respiratory symptoms and signs of infection occur. The high prevalence rates of melioidosis in Malaysia warrants better management options to improve quality of life, and life expectancy in patients with CF. Travel activities to endemic regions should also be given more consideration, as this would be crucial to identify and initiate appropriate empiric treatment.

    OBJECTIVE: The sole prospective longitudinal study of children with either chronic suppurative lung disease (CSLD) or bronchiectasis published in the current era was limited to a single center. We sought to extend this study by evaluating the longer-term clinical and lung function outcomes and their associated risk factors in Indigenous children of adolescents from Australia, Alaska, and New Zealand who participated in our previous CSLD or bronchiectasis studies during 2004-2010.

    METHODS: Between 2015 and 2018, we evaluated 131 out of 180 (72.8%) children of adolescents from the original studies at a single follow-up visit. We administered standardized questionnaires, reviewed medical records, undertook clinical examinations, performed spirometry, and scored available chest computed tomography scans.

    RESULTS: Participants were seen at a mean age of 12.3 years (standard deviation: 2.6) and a median of 9.0 years (range: 5.0-13.0) after their original recruitment. With increasing age, rates of acute lower respiratory infections (ALRI) declined, while lung function was mostly within population norms (median forced expiry volume in one-second = 90% predicted, interquartile range [IQR]: 81-105; forced vital capacity [FVC] = 98% predicted, IQR: 85-114). However, 43 out of 111 (38.7%) reported chronic cough episodes. Their overall global rating judged by symptoms, including ALRI frequency, examination findings, and spirometry was well (20.3%), stable (43.9%), or improved (35.8%). Multivariable regression identified household tobacco exposure and age at first ALRI-episode as independent risk factors associated with lower FVC% predicted values.

    CONCLUSION: Under our clinical care, the respiratory outcomes in late childhood or early adolescence are encouraging for these patient populations at high-risk of premature mortality. Prospective studies to further inform management throughout the life course into adulthood are now needed.

    Registry-based epidemiologic studies suggest associations between chronic inflammatory intestinal diseases and pancreatic ductal adenocarcinoma (PDAC). As genetic susceptibility contributes to a large proportion of chronic inflammatory intestinal diseases, we hypothesize that the genomic regions surrounding established genome-wide associated variants for these chronic inflammatory diseases are associated with PDAC. We examined the association between PDAC and genomic regions (±500 kb) surrounding established common susceptibility variants for ulcerative colitis, Crohn's disease, inflammatory bowel disease, celiac disease, chronic pancreatitis, and primary sclerosing cholangitis. We analyzed summary statistics from genome-wide association studies data for 8,384 cases and 11,955 controls of European descent from two large consortium studies using the summary data-based adaptive rank truncated product method to examine the overall association of combined genomic regions for each inflammatory disease group. Combined genomic susceptibility regions for ulcerative colitis, Crohn disease, inflammatory bowel disease, and chronic pancreatitis were associated with PDAC at P values < 0.05 (0.0040, 0.0057, 0.011, and 3.4 × 10-6, respectively). After excluding the 20 PDAC susceptibility regions (±500 kb) previously identified by GWAS, the genomic regions for ulcerative colitis, Crohn disease, and inflammatory bowel disease remained associated with PDAC (P = 0.0029, 0.0057, and 0.0098, respectively). Genomic regions for celiac disease (P = 0.22) and primary sclerosing cholangitis (P = 0.078) were not associated with PDAC. Our results support the hypothesis that genomic regions surrounding variants associated with inflammatory intestinal diseases, particularly, ulcerative colitis, Crohn disease, inflammatory bowel disease, and chronic pancreatitis are associated with PDAC. SIGNIFICANCE: The joint effects of common variants in genomic regions containing susceptibility loci for inflammatory bowel disease and chronic pancreatitis are associated with PDAC and may provide insights to understanding pancreatic cancer etiology.

    The thyroid status of 249 patients with chronic schizophrenia (males = 136, females = 113) with a median age of 36 years (range: 16 to 58 years) and a median duration of hospitalisation of 10 years (range: 1 to 30 years) was assessed. Thyroid antibodies (TAb) were found in 51 patients (20%). In female patients, 32 (28%) were TAb positive compared to 13% (n = 152, p = 0.01) in healthy female blood donors. In male patients, the prevalence of TAb was 14% compared to 7% (n = 449, p = 0.01) in healthy male blood donors. Of the 183 patients who had thyroid hormone measurements, 60% had normal test, 5% had elevated TSH and 17% had low TSH. The T4, FT41 and FT31 were significantly lower in those with low or high TSH (p < 0.001) compared to those with normal TSH. Of the 143 patients with normal TSH, 33 (23%) had low T3. In conclusion, there is a spectrum of thyroid function test abnormalities in chronic schizophrenia; this may be related to an abnormality in the central regulation of the hypothalamo-pituitary thyroid axis as well as at the peripheral level. However the association between chronic schizophrenia and the presence of thyroid antibodies, and the clinical relevance of these biochemical abnormalities, are still not clear.

    A prospective study was carried out to determine the aetiology of cerebral abscess in relation to the primary source of infections. Seventy-five patients with cerebral abscess were included in the study in the period January 1985 to December 1988. More than half of the patients studied had single lesions and the overall most common sites were in the frontal and parietal regions. Chronic suppurative otitis media, cyanotic congenital heart diseases and meningitis were among the important predisposing conditions in these patients. Approximately 25% of the patients with cerebral abscesses had no documented antecedent infections. Pure cultures were found to be predominant (66.7%) and sterile cultures were obtained from 10 (13.3%) patients. Streptococci were isolated from 23 (30.7%) patients, the commonest species being Streptococcus milleri. Proteus sp, Pseudomonas aeruginosa, Pseudomonas putrifaciens and Bacteroides sp were almost exclusively found in cerebral abscesses secondary to chronic suppurative otitis media; these organisms were found in mixed cultures. Streptococcus milleri, Bacteroides sp and Eikenella corrodens were found in pure cultures in patients with cyanotic congenital heart disease. In patients with ventriculoperitoneal shunts in-situ, Staphylococcus aureus, Staphylococcus epidermidis and diphtheroids were common. Anaerobes were found in 15 (20.0%) patients, the majority in mixed cultures. Culture, as well as gas-liquid chromatographic analysis of volatile fatty acids of cerebral pus, was carried out to enhance the detection of the anaerobes. Based on these findings, an antibiotic regimen consisting of penicillin, chloramphenicol and metronidazole is recommended as an initial therapy while awaiting culture and sensitivity results.

    Congo red screening of 211 consecutive cardiac biopsy specimens obtained during cardiac surgery from 167 patients revealed 26 (16%) instances of isolated atrial amyloidosis (IAA). The ages of IAA-positive patients ranged from 25 to 52 years (mean age, 39 years). Twenty-three (88%) IAA-positive biopsy specimens were from patients with chronic rheumatic heart disease (CRHD) while three (12%) were from patients with an atrial septal defect (ASD). The prevalence of IAA in the CRHD patients was 23%, appreciably higher than that in the ASD patients (15%) and in other patients with atrial biopsies. The prevalence of IAA in both CRHD and ASD patients was significantly higher (P < .001) than in controls. Controls consisted of 247 healthy adults who were autopsied after traumatic deaths, with an age range of 18 to 89 years (mean age, 38 years). Only seven (3%) control subjects were IAA positive; all were over 40 years of age. Isolated atrial amyloidosis deposits were permanganate resistant and immunohistochemically positive for human amyloid P (AP) protein and negative for human amyloid-associated (AA) protein and immunoglobulin light chains. They were observed as fine congophilic and birefringent deposits in intramyocardial vessel walls, along the myocardial sarcolemma, and in the subendocardium. There was associated myocyte hypertrophy but no atrophy. Electron microscopy demonstrated typical nonbranching amyloid fibrils. It is postulated that stretching of the atria in chronic heart disease results in a raised prevalence of IAA. Recent reports that IAA contains atrial natriuretic peptide, a polypeptide hormone product of atrial myocytes, supports this view.
