Effectiveness of interventions to prevent abuse in people living with dementia in community settings: A systematic review.

OBJECTIVES: This review examined the evidence for interventions to prevent the abuse of people living with dementia in the community. METHODS: The articles were retrieved from 2000 to 2023 from six databases, including MEDLINE via PubMed, CINAHL Plus via EBSCO, EMBASE, ProQuest Medical Library, Web of Science, and Scopus. The research articles that focused on finding the effectiveness of interventions for preventing abuse of people living with dementia in community settings were included in this review. The review included randomized controlled trials and pre-test post-test trials only. The quality appraisal of the eligible studies was done using ROB 2 and ROBINS II. The findings were tabulated and narratively synthesised. RESULTS: Out of 1831 articles, only three were included in this review. Only two RCTs were included in this efficacy review. Both the studies showed that the interventions were not effective in reducing abuse. The studies utilised family caregiver interventions like psychological interventions and online supportive education. The review identified psychological interventions with some evidence. Another study was a quasi-experimental study that used dialectical behaviour therapy as an intervention to reduce abuse occurrence. The study showed low evidence and focused only on reporting of elder abuse as an outcome. CONCLUSION: This review found very few studies and was not able to draw a conclusion on the effectiveness of interventions for abuse in people living with dementia. Given the paucity of research, there is a clear need to identify how to overcome the challenges faced in elder abuse research and further refine the development of approaches to reduce elder abuse among people living with dementia in community settings.

Rapidly Progressive Dementia in an Elderly Male: Perseverance Becomes the Key to a Rare Diagnosis.

Cognitive impairment in a patient with rapidly progressive dementia (RPD) develops faster than expected for a known dementia syndrome. It poses as a diagnostic challenge for the physician who must identify the diagnosis among a broad spectrum of differentials. Here, we discuss the case of a 60-year-old male who presented with a four-month history of progressive gait disturbance, incoherent talking, dysarthria, hand tremors, and new-onset bladder incontinence. Neurological examination revealed fast saccades, cerebellar dysarthria, hypertonia, and normal power in all four limbs, brisk reflexes, past pointing, intentional tremors, resting myoclonic jerks, and ataxic gait. Initial differentials of progressive paraneoplastic encephalitis, infectious encephalitis, and toxic encephalopathy were considered. However, the results of lumbar puncture and blood investigations-voltage-gated potassium channel (VGKC) antibody and N-methyl-D-aspartate (NMDA) receptor antibody, tumor markers, viral markers being negative and ammonia and lactate levels being normal led us to think of another possibility. With such rapidly progressive dementia, myoclonic jerks, extrapyramidal signs, and cerebellar signs, a diagnosis of Creutzfeldt-Jakob disease (CJD) was taken into consideration. A cerebrospinal fluid (CSF) sample was sent for CSF protein 14-3-3 quantification by enzyme-linked immunosorbent assay (ELISA) and came out positive. During his stay in the hospital, our patient developed multiple complications, and his clinical state progressively worsened. With no signs of improvement and the known fatal nature of the disease, the goals of care were discussed with the family and we all agreed on providing palliative care. The patient passed away on day 15 of hospital admission.

Acute and sub-chronic toxicity of Liberin, an anti-diabetic polyherbal formulation in rats.

BACKGROUND: The polyherbal formulation (PHF) liberin, is known to exert anti-hyperglycemic effects in type 2 diabetes mellitus. Hence, it is important to study the safety profile of PHF in the current study through acute and chronic toxicity evaluation. OBJECTIVES: This research aims to assess the acute and sub-chronic toxicity of PHF in rats. MATERIALS AND METHODS: PHF was administered once orally (1000 mg/kg body weight), and the rats (male and female) were monitored for toxicity signs for a 14-day period. For a 28-day chronic toxicity study, rats were daily administered with PHF dose of 500 mg/kg and 1000 mg/kg body weight. Rats were followed up for mortality, weight changes, and other morbidities. Further haematological, biochemical, and histopathological changes were assessed. RESULTS: No death related to treatment or toxicity signs were recorded in the acute single-dose administration group. The results showed that the PHF was tolerated well up to a dose of 1000 mg/kg body weight. Even at the high dose of 1000 mg/kg body weight, sub-chronic tests did not show any significant difference between the dosed and normal groups. No significant changes were seen in the histopathological analysis of the liver, spleen, and kidney as well as haematological and biochemical parameters in acute, sub-chronic and satellite groups following the administration of PHF. CONCLUSION: The results confirmed that there was no adverse effect of this PHF at the maximum dose of 1000 mg/kg body weight in Wistar rats. Further, no adverse delayed effects related to PHF were observed in the satellite group. Therefore, this PHF appears safe for therapeutic purposes in the Ayurvedic medicinal system.

Acute Cryptococcal Meningitis in a Patient With Idiopathic CD4 Lymphocytopenia: A Rare Clinical Entity.

Cryptococcal meningitis is a known cause of opportunistic infection in immunocompromised patients, especially those with AIDS. Very few cases exist in literature where cryptococcal meningitis is seen in patients without evidence of HIV infection. Here, we describe a case of an elderly woman presenting with clinical features of meningitis. Our patient tested positive for cryptococcal antigen (CRAg) in the CSF and growth of Cryptococcus neoformans was obtained in CSF culture. Further laboratory investigations revealed CD4 lymphocytopenia (233 cells/µl) in the absence of HIV infection. When we checked the CD4 count, beyond a period of six weeks, it was reported to be low, which confirmed our diagnosis of idiopathic CD4 lymphocytopenia (ICL). She was successfully treated with amphotericin B along with flucytosine for two weeks and discharged on maintenance antifungal therapy for eight weeks. This case emphasizes the need to maintain a high index of suspicion and consider the possibility of opportunistic infections even in the absence of HIV infection for timely diagnosis and treatment.

Anthropometric Indices and Type 2 Diabetes Mellitus as a Risk Factor in Predicting Nonalcoholic Fatty Liver Disease - A Prospective Study in Indian Population.

Background: The different anthropometric indices have different predictive values of nonalcoholic fatty liver disease (NAFLD) in various populations. Since obesity is a common cause of NAFLD and diabetes, therefore, it is critical to correlate the various anthropometric indices as a risk factor in terms of NAFLD and diabetes in the Indian population. In view of reported association between obesity and NAFLD, the study was employed to analyze the relationship of various anthropometric indices (body mass index [BMI], a body shape index [ABSI], waist-height ratio [WHtR], etc.) with NAFLD and to comment, if possible, which among them has the highest predictive value in patients with type 2 diabetes. Material and Methods: Data of 220 diabetic patients (36-80 years) were analyzed. Anthropometric data were collected using standard methods. Routine biochemical investigations data were used. Ultrasonography was used to assess liver status for NAFLD. Results: Based on the results, Waist height ratio [WHtR] and BMI had better correlation with NAFLD than ABSI. The desirable WHtR cutoff value was 0.545 with 62% of sensitivity and 62% of specificity. The cut off for BMI and ABSI were 24.6 and 0.805, respectively, with 65% of sensitivity and 62% of specificity for BMI and 63% of sensitivity and 42% of specificity for ABSI. Conclusion: There is a strong association of BMI and ABSI with NAFLD in this study. Public health measures to limit overnutrition and management of obesity are essential to prevent NAFLD, and as its negative health effects on type 2 diabetes mellitus.

Safety profile of COVID-19 vaccines, preventive strategies, and patient management.

INTRODUCTION: Fast-track approval has led to serious concerns on the perception of COVID-19 vaccines' safety among the public. Common adverse drug reactions (ADRs) of COVID-19 vaccines are minor localized reactions, while systemic ADRs have been reported rarely. The serious ADRs include anaphylaxis, vaccine-induced immune thrombotic thrombocytopenia syndrome (VITTS), and reactions related to the pharmaceutical excipients present in the vaccine. A comprehensive review on the safety of COVID-19 vaccines would help in early identification and better management of ADRs. This literature review was conducted using PubMed, Google Scholar, COVID-19 Vaccine package inserts, and UpToDate. AREAS COVERED: This article provides various aspects of COVID-19 vaccine safety and offers strategies to prevent and clinically manage suspected ADRs related to COVID-19 vaccines. EXPERT OPINION: A careful consideration of contraindications and patient education on early identification of serious ADRs are the cornerstones in tackling safety concerns associated with COVID-19 vaccines. Most of the mild ADR cases are manageable with over-the-counter medications, while the serious ones may require physician oversight and hospitalization. It is also mandatory to report all ADRs to the local pharmacovigilance centers, with a higher priority given to the moe significant ones, in order to improve vaccine safety data.

Age Related Prevalence of Mild Cognitive Impairment in Type 2 Diabetes Mellitus Patients in the Indian Population and Association of Serum Lipids With Cognitive Dysfunction.

The magnitude of type 2 diabetes mellitus (T2DM) is ever-increasing in India, and at present, ~77 million people live with diabetes. Studies have established that T2DM increases the risk of neurodegenerative disorders. This study aimed to determine the age-related prevalence of mild cognitive impairment (MCI) in T2DM patients in the Indian population and to identify link between cognitive dysfunction in T2DM patients and serum lipid composition through untargeted and targeted lipidomic studies. Using a cross-sectional study, we evaluated 1278 T2DM patients with Montreal cognitive assessment test (MoCA) and digit symbol substitution test (DSST) for cognitive functions. As per MoCA, the prevalences of MCI in T2DM patients in age groups below 40, 41-50, 51-60, 61-70, 71-80 and 81-90 years were 13.7, 20.5, 33.5, 43.7, 57.1 and 75% with DSST scores of 45.8, 41.7, 34.4, 30.5, 24.2 and 18.8% respectively. Binomial logistic regression analysis revealed serum HbA1c ≥ 7.51, duration of T2DM over 20 years, age above 41 years, and females were independent contributors for cognitive dysfunction in T2DM patients. Preliminary studies with untargeted lipidomics of the serum from 20 T2DM patients, including MCI and normal cognition (NC) group, identified a total of 646 lipids. Among the identified lipids, 33 lipids were significantly different between MCI and NC group, which comprised of triglycerides (TGs, 14), sphingolipids (SL, 11), and phosphatidylcholines (PC, 5). Importantly, 10 TGs and 3 PCs containing long-chain polyunsaturated fatty acids (PUFA) were lower, while 8 sphingolipids were increased in the MCI group. Since brain-derived sphingolipids are known to get enriched in the serum, we further quantified sphingolipids from the same 20 serum samples through targeted lipidomic analysis, which identified a total of 173 lipids. Quantitation revealed elevation of 3 species of ceramides, namely Cer (d18:1_24:1), Hex1Cer (d16:0_22:6), and Hex2Cer (d28:1) in the MCI group compared to the NC group of T2DM patients. Overall, this study demonstrated an age-related prevalence of MCI in T2DM patients and highlighted reduced levels of several species of PUFA containing TGs and PCs and increased levels of specific ceramides in T2DM patients exhibiting MCI. Large-scale lipidomic studies in future could help understand the cognitive dysfunction domain in T2DM patients, while studies with preclinical models are required to understand the functional significance of the identified lipids.

Abiotrophia defectiva: A Rare but Critical Cause of Infective Endocarditis.

Infective endocarditis (IE) refers to an infection involving the endocardial surface of the heart. Most of the cases of IE are known to occur due to infection by viridans Streptococci or Staphylococci species. Abiotrophia defectiva is known to cause less than 1% of cases of IE. Though rare, this organism can cause life-threatening complications such as septic embolization, destruction of heart valves, and heart failure if not detected and treated timely. Here we discuss a case of a 44-year-old female who presented to our tertiary care centre with complaints of fever and easy fatiguability for two weeks. After further investigations, she was finally diagnosed to have IE due to Abiotrophia defectiva. Imaging demonstrated the presence of embolic and valvular complications as well. Through this case, we highlight the importance of early detection and timely management of this condition in order to decrease the occurrence of fatal complications and mortality.

Intractable Vomiting and Hiccups: An Atypical Presentation of Neuromyelitis Optica.

Neuromyelitis optica is an inflammatory disorder of the central nervous system. It involves the immune-mediated demyelination of predominantly the optic nerves and the spinal cord, which can lead to optic neuritis and transverse myelitis, respectively. Patients usually present with symptoms related to the eyes or the spinal cord, like loss of vision, pain in the eyes, visual field defects or numbness and weakness of limbs. Vomiting and hiccups are common cases encountered in medicine clinics and can sometimes be an atypical presentation of this disorder. Here we present a case of a 33-year-old female who initially presented to our tertiary care centre with repeated episodes of bilious vomiting and intractable hiccups for 10 days. After multiple investigations over a couple of days, the patient was found to be positive for anti-NMO antibodies and displayed neuro-radiological findings on MRI brain and spine, which finally led to the diagnosis of neuromyelitis optica spectrum disorder (NMOSD). Through this case we highlight the importance of suspecting NMO in a patient with complaints of intractable vomiting and hiccups, so that early intervention and treatment can prevent further disabling complications of the disease.

Weil syndrome causing autoimmune haemolytic anaemia.

Weil syndrome is a fulminant form of leptospirosis, usually caused by spirochetal organism Leptospira interrogans. It is characterized by icterus, petechial rashes over the body, signs of renal failure and hepatic failure. Anaemia is a usual manifes- tation of Leptospira infection, but autoimmune haemolytic anaemia is rare. We report a patient with autoimmune haemolytic anaemia following Leptospira infection, which was responsive to high-dose steroid therapy.

Guillain-Barre Syndrome with Falciparum Malaria and Scrub Typhus Mixed Infection-An Unusual Combination.

Guillain-Barre Syndrome is very rare in parasitic and rickettsial infection. Here we report a case of Plasmodium falciparum and scrub typhus mixed infection, presented with quadriparesis. Clinical, Serological, CSF analysis and Nerve Conduction Studies were consistent with Acute Inflammatory Demyelinating Polyneuropathy (variant of GBS). After administration of antimalarials and antibiotics for the mixed infection, patient gradually improved.

Prognosis of left ventricular systolic dysfunction in septic shock patients.

INTRODUCTION: The prognosis of myocardial dysfunction in critically ill patients with sepsis and its association with mortality is controversial. We aim to determine the significance of left ventricular systolic dysfunction in septic shock patients and their associated outcome. MATERIALS AND METHODS: A prospective, single center, observational study was carried out at an intensive care unit of a tertiary care hospital. A total of 66 patients diagnosed with septic shock were enrolled in the study from September 2010 to June 2012. The 2D echocardiography was performed for all the patients. Ejection fraction <50% was the diagnosing parameter for the patients with systolic dysfunction in septic shock. Acute Physiology and Chronic Health Evaluation III (APACHE III) score was calculated. RESULTS: The mean age of patients were found to be 53.71 ± 16.76 years. The mortality rate was found to be 48.48% and among them 43.75% patients had ejection fraction <50%. Non-survivors exhibited significantly lower mean blood pressure (74.19 ± 10.28 versus 80.59 ± 11.31; p = 0.008), lower ejection fraction (52.59 ± 16.37 versus 62.56 ± 8.31; p = 0.029) and higher APACHE III score (89.34 ± 15.41 versus 70.65 ± 13.27; p <0.001). The receiver operating characteristic curves APACHE III score (area under curve = 0.830) and ejection fraction (area under curve = 0.656) were used to predict the mortality in septic patients. CONCLUSION: Low ejection fraction, a marker to measure left ventricular systolic dysfunction is a predictor of mortality in septic shock patients. However, more research is needed to confirm the findings.

Cellulitis-like fixed drug eruption attributed to paracetamol (acetaminophen).

Paracetamol (acetaminophen) is a widely used analgesic-antipyretic with consistent safety profile and very low incidence of side effects. We report a case of biopsy-confirmed fixed drug eruption associated with paracetamol and presenting like cellulitis.
