Proportion and Factors Associated with Depressive Symptoms among Elderly in an Urban Slum in Bangalore

Depression among elderly is emerging as an important public health issue in developing countries like India. Published evidence regarding the magnitude and determinants of depression among elderly hailing from urban slum is currently limited. Hence, the current study was conducted to assess magnitude of the problem and identify factors associated with depression among the elderly in an urban slum. A cross-sectional study was done to cover total of473 elderly persons from an urban slum in Bangalore, India. They were assessed for depression using Center for Epidemiologic Studies Depression scale. The overall prevalence of depression was found to be 37.8 (95 % CI = 33.43–42.16). Multivariate analysis revealed that unemployment (self or children) (odds ratio (OR) 2.6; 95 % confidence interval (CI) 1.41–4.72), illness of self (OR 2.2; 95 % CI 1.45–3.21), female gender (OR 1.9; 95 % CI 1.19–2.89), conflicts in family (OR 1.6; 95 % CI 1.03–2.43), and marriage of children or grandchildren (OR 1.6; 95 % CI 1.02–2.68) as independent risk factors. Depression among elderly is an important health issue of this area. Psychological intervention need to be provided for all elderly persons especially at the time of being diagnosed with any kind of illness. Strategies should be targeted to the females. The stressful life events need to be identified and remedial actions taken. This facility should be made available to them at the primary level of health care. There is a need to include screening of depression in our national health programs.     

Influence of polycystic ovary syndrome on the periodontal health of Indian women visiting a secondary health care centre

Objectives

Periodontal disease and polycystic ovary syndrome (PCOS) share risk factors like obesity, insulin resistance, and dyslipidemia, along with evidence of chronic inflammation in the two conditions. Evaluating the influence of PCOS on periodontal health would, therefore, identify a possible association.

Materials and methods

Sixty women, divided into equal groups of PCOS and healthy patients, were clinically examined for periodontal parameters like probing depth (PD), plaque index (PI), modified gingival index (mGI), and bleeding on probing (BOP). Fasting blood sugar (FBS), insulin (FI), triglycerides (TG), and free testosterone along with serum and gingival crevicular fluid (GCF) levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were the biochemical parameters evaluated.

Results

Women with PCOS had statistically significant differences in mGI, PI, testosterone, FBS, and TG when compared with healthy women (p < 0.05). MDA levels in serum and GCF between women with PCOS and controls were also significantly different. BOP and mGI showed a moderate positive correlation (r = 0.45 and 0.44) with serum levels of MDA. Relatively greater gingival inflammation was observed in patients with PCOS compared to healthy controls, independent of the risk factors present.

Conclusion

PCOS seemed to have an impact on gingival inflammation, in addition to the effect of dental plaque and other local factors in the oral cavity, in PCOS patients when compared with healthy individuals.

Clinical relevance

Women diagnosed with PCOS may have probabaility of co-existing gingival inflammation. Therefore, emphasis on medical treatment for PCOS and periodic screening for periodontal disease may be warranted.

     

Society of Abdominal Radiology (SAR) and European Society of Urogenital Radiology (ESUR) joint consensus statement for MR imaging of placenta accreta spectrum disorders

This study was conducted in order to establish the joint Society of Abdominal Radiology (SAR) and European Society of Urogenital Radiology (ESUR) guidelines on placenta accreta spectrum (PAS) disorders and propose strategies to standardize image acquisition, interpretation, and reporting for this condition with MRI. The published evidence-based data and the opinion of experts were combined using the RAND–UCLA Appropriateness Method and formed the basis for these consensus guidelines. The responses of the experts to questions regarding the details of patient preparation, MRI protocol, image interpretation, and reporting were collected, analyzed, and classified as “recommended” versus “not recommended” (if at least 80% consensus among experts) or uncertain (if less than 80% consensus among experts). Consensus regarding image acquisition, interpretation, and reporting was determined using the RAND–UCLA Appropriateness Method. The use of a tailored MRI protocol and standardized report was recommended. A standardized imaging protocol and reporting system ensures recognition of the salient features of PAS disorders. These consensus recommendations should be used as a guide for the evaluation of PAS disorders with MRI. • MRI is a powerful adjunct to ultrasound and provides valuable information on the topography and depth of placental invasion. • Consensus statement proposed a common lexicon to allow for uniformity in MRI acquisition, interpretation, and reporting of PAS disorders. • Seven MRI features, namely intraplacental dark T2 bands, uterine/placental bulge, loss of low T2 retroplacental line, myometrial thinning/disruption, bladder wall interruption, focal exophytic placental mass, and abnormal vasculature of the placental bed, reached consensus and are categorized as “recommended” for diagnosing PAS disorders.     

Atrioesophageal Fistula in the Era of Atrial Fibrillation Ablation: A Review

The purpose of this review is to understand the epidemiology, clinical features, etiopathogenesis, and management of atrioesophageal fistula (AEF) after atrial fibrillation (AF) ablation. The incidence of AEF after AF ablation is 0.015%-0.04%. The principal clinical features include fever, dysphagia, upper gastrointestinal bleeding, sepsis, and embolic strokes. The close proximity of the esophagus to the posterior left atrial wall is responsible for esophageal injury during ablation. Prophylactic proton pump inhibitors, esophageal temperature monitoring, visualization of the esophagus during catheter ablation, esophageal protection devices, and avoidance of energy delivery in close proximity to the esophagus play an important role in preventing esophageal injury. Early surgical repair or esophageal stenting are the mainstay of treatment. Eliminating esophageal injury during AF ablation is of utmost importance in preventing AEF. A high index of suspicion and early intervention is necessary to prevent fatal outcomes.     

β-T594M epithelial sodium channel gene polymorphism and essential hypertension in individuals of Indo-Aryan ancestry in Northern India

Background

The T594M variant of the β-subunit of the sodium epithelial channel (ENaC) gene may contribute to hypertension in individuals of Indo-Aryan origin.

Methods

Present study was performed to assess the role of the ENaC gene variant as an independent risk factor for hypertension in subjects of Indo-Aryan ancestry. A total of 150 patients of recently detected essential hypertension and 150 matched controls were genotyped for the T594M polymorphism of the ENaC gene by PCR–RFLP method.

Results

β-T594M mutation was found to be non-polymorphic. There was major genotype call in both the groups i.e. cases and controls. Other phenotypic parameters like age, sex and body mass index were also similar among hypertensive patients and controls (P > 0.05). Hypertensive patients had significantly higher total cholesterol and triglycerides compared with controls (P < 0.0001).

Conclusion

These results do not suggest an important role for the T594M variant of the ENaC gene contributing to either the development or severity of hypertension in subjects of Indo-Aryan ancestry.

Immune response to hepatitis B vaccination in drug using populations: A systematic review and meta-regression analysis

Injecting and non-injecting drug users are at increased risk of contracting HBV infection, and show lower antibody response to hepatitis B vaccination compared to the general population. This systematic review and meta-regression analysis aimed to estimate seroprotection rates and identify host or vaccine factors associated with varying immune response following hepatitis B vaccination in drug using populations. Original research articles were searched using online databases (Medline, PubMed, and Embase) and from reference lists of eligible articles. HBV vaccine intervention studies reporting seroprotection rates in drug users, published in English during or after 1989 were eligible. Of 978 citations reviewed, 11 studies were eligible and included for final analysis. The reported seroprotection rates ranged from 54.5% to 97.1%. The studies were significantly heterogeneous (Q = 180.850, p = 0.000). Measurement of anti-HBs antibody at 2 months after the third vaccine dose (RR = 2.62, 95%CI = 1.16–5.94, p = 0.026) was significantly associated with higher seroprotection rates compared to measurement at 1 month and 6 month following third vaccine dose. Age, gender, current drug use, vaccine dose and schedule, anti-HBc, anti-HCV and anti-HIV antibody seropositivity, and proportion of IDU study population did not show a significant association with seroprotection rates. Recommendations for future research include the definition of a standardized time point for the measurement of anti-HBs antibody levels, to enhance comparability of the immune response between different studies. Studies should strive to accurately report all potentially relevant factors affecting immune response to vaccine. Long-term follow up studies are needed to assess the seroprotection status in drug using populations receiving hepatitis B vaccine by standard or accelerated schedules.     

Serum Bactericidal Assays To Evaluate Typhoidal and Nontyphoidal Salmonella Vaccines

Invasive Salmonella infections for which improved or new vaccines are being developed include enteric fever caused by Salmonella enterica serovars Typhi, Paratyphi A, and Paratyphi B and sepsis and meningitis in young children in sub-Saharan Africa caused by nontyphoidal Salmonella (NTS) serovars, particularly S. enterica serovars Typhimurium and Enteritidis. Assays are needed to measure functional antibodies elicited by the new vaccines to assess their immunogenicities and potential protective capacities. We developed in vitro assays to quantify serum bactericidal antibody (SBA) activity induced by S. Typhi, S. Paratyphi A, S. Typhimurium, and S. Enteritidis vaccines in preclinical studies. Complement from various sources was tested in assays designed to measure antibody-dependent complement-mediated killing. Serum from rabbits 3 to 4 weeks of age provided the best complement source compared to serum from pigs, goats, horses, bovine calves, or rabbits 8 to 12 weeks of age. For S. Enteritidis, S. Typhimurium, and S. Typhi SBA assays to be effective, bacteria had to be harvested at log phase. In contrast, S. Paratyphi A was equally susceptible to killing whether it was grown to the stationary or log phase. The typhoidal serovars were more susceptible to complement-mediated killing than were the nontyphoidal serovars. Lastly, the SBA endpoint titers correlated with serum IgG anti-lipopolysaccharide (LPS) titers in mice immunized with mucosally administered S. Typhimurium, S. Enteritidis, and S. Paratyphi A but not S. Typhi live attenuated vaccines. The SBA assay described here is a useful tool for measuring functional antibodies elicited by Salmonella vaccine candidates.
