Is handgrip strength a useful tool to detect slow walking speed in older Indian adults: A cross-sectional study among geriatric outpatients in a tertiary care hospital in South India.

Objectives: To determine whether handgrip strength can be used as a proxy for detecting slow walking speed in older adults. Measuring walking speed in older adults can be challenging as cognitive and functional decline may have a significant impact on test performance. Methods: Hundred subjects aged >/= 60 were recruited. Slow walking speed was defined as walking speed <1.0 m/s. Handgrip strength was measured using handheld dynamometer. Multiple linear regression analysis was used to determine the relationship between the two. Results: The mean age of the study participants was 67.8±6.2 years. There were 63 males and 37 females. The mean handgrip strength of the participants was 23±5.9 kgs. Older subjects had slow gait speed (r=-0.40, p<0.001) while patients with higher BMI (r=0.36, p<0.001), handgrip strength (r=0.72, p<0.001) and appendicular lean mass (r=0.53, p<0.001) had normal gait speed. On multiple linear regression analysis, only handgrip strength (OR 0.71; 95% CI 0.58-0.87, p=0.001) and nutritional status (OR 8.60; 95% CI 1.98 - 37.40, p=0.004) were found to have a significant association with walking speed. Conclusions: Our study shows that handgrip strength assessment can be used as a surrogate indicator for detecting slow walking speed. Large population studies are warranted to examine its validity.

Prevalence and factors contributing to primary sarcopenia in relatively healthy older Indians attending the outpatient department in a tertiary care hospital: A cross-sectional study.

BACKGROUND: Literature is scarce on primary sarcopenia among Indian older adults. This study was aimed to estimate the prevalence of primary sarcopenia among older persons in India using the European Working Group on Sarcopenia in the Older People 2010 (EWGSOP) diagnostic criteria and to elucidate the factors leading to its development. METHODOLOGY: Two hundred twenty-seven subjects over 60 years of age attending the geriatric outpatient clinic were recruited for the study. Sarcopenia was diagnosed based on set criteria for gait speed, handgrip, and skeletal muscle mass assessment by dual-energy x-ray absorptiometry. RESULT: The prevalence of primary sarcopenia in the study population was 39.2% (n = 89). Male patients were more sarcopenic than women, 47% (n = 72) vs 23% (n = 17). Obese subjects (body mass index > 25 kg/m2) had a lower prevalence of sarcopenia (odds ratio = 0.10; 95% confidence interval = 0.05-0.19). There was no association between sarcopenia and other postulated risk factors like low vitamin D levels, dietary protein or carbohydrate intake, or sedentary lifestyle. CONCLUSION: Contrary to published data, primary sarcopenia appears to be higher among older Indians using presently available guidelines. Community studies with validated cutoffs suited for the Indian subcontinent may yield a lower prevalence of primary sarcopenia.

Acute colonic pseudo-obstruction in two patients admitted with severe acute respiratory syndrome-coronavirus-2 pneumonia.

We have described two cases of severe SARS-CoV-2 pneumonia presenting with acute colonic pseudo-obstruction with normal liver enzymes and serum lactate. These older adults presented predominantly with constitutional symptoms, silent hypoxia, distended abdomen, sluggish bowel sounds, and colonic dilatation supported by abdominal imaging (plain X-ray and computerized tomography of abdomen) to a tertiary care center in South India. Both patients received standard treatment for severe SARS-CoV-2 pneumonia and acute colonic pseudo-obstruction according to available guidelines but succumbed to complications during hospital stay. Acute colonic pseudo-obstruction in patients admitted with SARS-CoV-2 infection requires high index of suspicion as it warrants early mitigation by cessation of offending agents, optimizing electrolytes, and colonic decompression to prevent morbidity and mortality.

Psychological impact of infection with SARS-CoV-2 on health care providers: A qualitative study.

BACKGROUND: Rapid increase in severe acute respiratory syndrome coronavirus 2 (SAR-CoV-2) infection has also affected many health care providers (HCPs). This study aims to understand personal stories of HCPs affected by SARS-CoV-2, which could help with insights about ways to support them. METHODS: Using a phenomenological approach and purposive sampling method, we recruited participants for semi-structured interviews through a telephone. Data saturation was achieved by the 11th participant and two more interviews were performed to confirm the same. Interviews were transcribed, and a seven-step Colaizzi method was used to identify different themes. RESULTS: The psychological impact of SARS-CoV-2 on HCPs who tested positive can be summarized into four broad themes. These are challenges faced by HCPs, social concerns, experience of quarantine period, and positive experiences. Challenges they faced were about dealing with uncertainty, fear of spreading infection, and stigma. In the social concerns theme, what featured was concerns about family, social support from friends and hospital, and stigmatizing experience in neighborhood. In the quarantine experience theme, self-care and desperation to connect prominently colored their emotional and psychological experience. There were positive experiences also, which included personal strength, sense of gratitude, growth, and professional commitment. CONCLUSION: The personal stories of HCPs highlight that while they coped effectively during the recovery process, it may be important to address psychosocial factors of well-being as they worked with patients testing positive for SARS-CoV-2.

Diagnostic methods and identification challenges experienced in a Burkholderia contaminans outbreak occurred in a tertiary care centre.

BACKGROUND: Recently, a novel species contaminans belonging to the family Burkholderia cepacia complex (Bcc) is rising as a hospital pathogen. Detection of Burkholderia contaminans, a member of Bcc can be done only by MALDI TOF and sequencing techniques. We report the diagnostic challenges faced in an outbreak of bacteremia due to B. contaminans grown in diltiazem vials. METHOD: The department of microbiology notified the infection control team about a cluster of eleven patients with B. contaminans isolated from blood culture. An outbreak investigation was initiated by performing environmental surveillance and sterility testing of solutions given for the patients. Routine phenotypical methods for identification of species followed by MALDI-TOF and sequencing was performed to identify the pathogen. RESULTS: All the patients detected with B. contaminans were having cardiac disease and received diltiazem. Sterility testing of diltiazem vials given for the patient and an unopened vial of same batch has grown B. contaminans. Clonal typing has confirmed the sequence similarities between patient and solution isolates. CONCLUSION: Due to diagnostic challenge in identifying the species of Bcc, MALDI TOF and clonal typing remains the key diagnostic tools available to detect Bcc species at an earliest especially in an outbreak.

Clinical Profile and Predictors of Outcomes in Older Inpatients with Pyelonephritis in a Tertiary Care Hospital in Southern India.

BACKGROUND: Pyelonephritis is a serious infection associated with significant morbidity and mortality in the elderly with an estimated annual incidence rate of around 10% from previous studies. Older people are at a higher risk for pyelonephritis due to multiple factors including structural, functional and co-existent conditions. There is very little data on the incidence, clinical features and outcomes among elderly patients with pyelonephritis in India. MATERIALS AND METHODS: We performed a retrospective review of case records of 100 consecutive patients over the age of 60 years with pyelonephritis admitted to a tertiary care hospital. RESULTS: One fourth of our patients (26%) did not have fever, 49% had delirium and 52% had systemic inflammatory response syndrome (SIRS). Sixty five percent of the patients were diabetic and 60% had infections caused by extended spectrum beta lactamase (ESBL) producing organisms. As in other studies, the commonest organism isolated was E.coli (49%). A low serum albumin level was a predictor of mortality (p<0.001) and increased length of hospital stay (p<0.005). Delirium was also associated with a poor outcome (p=0.009) in these patients. Patients with pyelonephritis secondary to ESBL producing organisms had a higher length of stay (p<0.005). CONCLUSION: Hypoalbuminemia and delirium predicted poor outcomes in our patients. We found a high prevalence of ESBL infections in this study. Further research is required to assess the efficacy of aggressive management of delirium and low albumin in improving health and cost outcomes.

Ornidazole-induced ataxia in an Indian woman: A case report.

The nitroimidazole group of antibiotics like metronidazole have been reported to cause cerebellar ataxia as a rare side effect. Ornidazole, the newest derivative of this class, has a long half life and is very rarely known to cause cerebellar ataxia. Here, we report a 61-year-old patient who developed ataxia due to ornidazole to highlight an unusual adverse event that improved rapidly after discontinuation of the offending drug.
