Comprehensive, continuous, and compulsory monitoring of frailty in elderly

Background

The increasing elderly population makes frailty an increasing concern in society with vulnerability to stress and functional decline. Unrecognised comorbidities are common among the elderly due to lack of mention by the patients. Physicians should be equipped with effective interviewing skills along with the use of screening tools to assess any impairments in activities of daily living, cognition and signs of depression.

Objectives

To measure the degree of independence or dependence using scales and stratify patients based on Clinical Frailty Scale (CFS) so as to recommend it as a routinely usable tool.

Materials and Methods

In total, 191 elderly subjects above the age of 65 years were recruited for geriatric assessment. Tools that assess performance in daily living activities and cognition were used. The prevalidated CFS was used to score frailty to stratify patients into frail and non-frail groups, and the parameters were compared.

Results

Mean age of the study population was 69.54 years with 53.4% males and 46.6% females. Mean Katz index and mean Lawton score were >5. The mean Global Deterioration Scale (GDS) score was 1.5, and the mean clinical frailty score was 3.55. Significantly high number of male individuals were found in the frailty group. Hypertension was significantly higher in the frail group. The mean Katz scores were significantly lower, and mean GDS scores were significantly higher in the frailty group. Multivariable logistic regression has shown gender to be an important determinant of frailty with an odds ratio of 0.05 (CI-0.01-0.20). The higher Lawton score and GDS scores were significantly associated with frailty with an odds ratio of 0.33 (CI: 0.21-0.52) and 2.62 (CI: 1.14-6.02), respectively.

Conclusion

Men are more frail than women and co-morbidities like hypertension and coronary artery disease contribute to frailty with cognitive decline and decreased autonomy. A comprehensive assessment to identify frailty will provide a holistic view of well being among the elderly.

Arterial Oxygen Saturation: A Vital Sign?

ABSTRACT

The physical examination is a key part of a continuum that extends from the history of the present illness to the therapeutic outcome. An understanding of the pathophysiological mechanism behind a physical sign is essential for arriving at the correct diagnosis. Early detection of deteriorating physical/vital signs and their appropriate interpretation is thus the key to achieve correct and timely management. By definition, vital signs are "the signs of life that may be monitored or measured, namely pulse rate, respiratory rate, body temperature, and blood pressure." Vital signs are the simplest, cheapest and probably the most inexpensive information gathered bedside in outpatient or hospitalized patients. The pulse oximeter was introduced in the 1980s. It is an accurate and non-invasive method for the measurement of arterial hemoglobin oxygen saturation (SaO2). Pulse oximetry-based arterial oxygen saturation can be effectively used bedside in in-hospital and ambulatory patients with diagnosed or suspected lung disease. The present pandemic of COVID-19 should be considered as a wake-up call. Articles related to arterial oxygen saturation and its importance as a vital sign in patient care were searched online especially in PubMed. Available studies were studied in full length and data was extracted. Discussion: A. Clinical Utility of Oxygen Saturation Monitoring: There are many studies reporting the clinical applicability and usefulness of pulse oximetry in the early detection of hypoxemic events during intraoperative and postoperative periods. B. Role of clinical expertise accompanied by knowledge of physiology: A diagnostic sign is useful only if it is interpreted accurately and applied appropriately while evaluating a patient. The World Health Organisation also appreciates these facts and published "The WHO Pulse Oximetry Training Manual." Understanding the physiology behind and overcoming limitations of the diagnostic sign by clinical expertise is important. While using pulse oximetry, a clinician needs to keep in mind the sigmoidal nature of the oxygen-Hb dissociation curve. Considering these benefits of SaO2 measurement, there have been several references in the past to consider oxygen saturation as the fifth vital sign. In the present pandemic oxygen saturation i.e., SpO2 (arterial oxygen saturation) measured by pulse oxymeter, has been the single most important warning and prognostic sign be it for households, offices, street vendors, hospitals or governments. Measurement of trends of SaO2 added with respiratory rate will provide clinicians with a holistic overview of respiratory functions and multidimensional conditions associated with hypoxemia.

Yoganidra to Alleviate Anxiety: An Interventional Study

INTRODUCTION

Anxiety and stress are challenging conditions that result in perturbation of the body's homeostasis. It disturbs one's physical and mental state of equilibrium. There are many ways to overcome anxiety and stress, however, the best among many remedies is yoganidra, as it achieves optimum functioning of not only our body but also our mind. Hence, the present study was planned to evaluate the impact of yoganidra practice on the anxiety levels of undergraduate students.

AIMS AND OBJECTIVES

This study aimed to evaluate physiological parameters like pulse rate, blood pressure, and respiratory rate, measure anxiety levels by the general anxiety disorder-7 (GAD-7) inventory and Beck's anxiety questionnaire, conduct yoganidra sessions for all the students, and compare the effects of these training sessions on physiological parameters and anxiety scales.

MATERIALS AND METHODS

The present study was carried out in the department of physiology, R.V.M. Institute of Medical Sciences and Research Center, Siddipet, and conducted on 125 students from first to final Bachelor of Medicine, Bachelor of Surgery who participated voluntarily and actively after satisfying the inclusion and exclusion criteria. All the members were assessed for physiological cardio-respiratory parameters followed by the GAD-7 scale and Beck's anxiety questionnaire pre- and post-yoganidra sessions.

RESULTS

There was a significant difference in blood pressure before and after the session, whereas the pulse rate and respiratory rate reduction after the session were highly significant. There was a highly significant reduction in GAD-7 anxiety score, from 12±3.41 to 5.80±2.56 (p<0.0001); while for Beck's score, there was a highly significant reduction in anxiety score of 20.83±0.73 after giving yoganidra training as opposed to the earlier score of 23.75±1.86 (p<0.0001).

CONCLUSION

Yoganidra provides ways to manage stress and anxiety and enhance mental wellness. It is supported by research evidence as a safe and effective method to reduce anxiety.

Impact of COVID-19 on thyroid gland functions with reference to Graves' disease: A systematic review

Coronavirus disease 2019 (COVID-19) is caused due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Both immediate and long-term adverse effects arise out of this disease's aftermath. It involves various organs, which include endocrine glands, nervous system, musculoskeletal system, and other organs. The long-term outcomes of the SARS-CoV-2 infection are influenced by preexisting comorbidities. Genetic, environmental, and immunological factors contribute to the development of various autoimmune diseases, which include Graves' disease (GD). The growing mystery surrounding this virus is exacerbated by auto-inflammatory diseases, such as pediatric inflammatory multisystemic syndrome (PIMS) or multisystem inflammatory syndrome in children (MIS-C), which raises concerns about the nature of the virus' connection to the autoimmune and auto-inflammatory sequelae. There is a need to understand the underlying mechanisms of developing GD in post-COVID-19 patients. There are limited data regarding the pathogenesis involved in post-COVID-19 GD. Our goal was to understand the various mechanisms involved in post-COVID-19 GD among patients with confirmed COVID-19 infection. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for 2020, a literature search of medical databases (PubMed, Cochrane Central Register of Controlled Trials, and Scopus) from February 2021 to February 2022 was performed by five authors. The keywords used were "Post COVID-19," "Grave's disease," "Cytokine storm," "Autoimmunity," and "Molecular mimicry." This review revealed three underlying mechanisms that resulted in post-COVID GD, which included cytokine storm, molecular mimicry, ACE2 receptor concentration, and cell-mediated immunity. The full spectrum of the effects of COVID-19 needs to be researched.

A study of spectrum of sickle cell anemia and thalassemia in a teaching institute of South India

Background and Aim

Sickle cell syndrome is a group of inherited hematological disorders with varying degrees of anemia, jaundice, fatiguability along with hepatomegaly and splenomegaly. The clinical presentations can be may vary and therefore require thorough investigations. We tried to evaluate the spectrum of sickle cell anemia and thalassemia in pediatric patients of our hospital.

Patients and Methods

In this cross-sectional study, A total of n = 200 consecutive cases were detected during the period of study. A thorough history and detailed clinical examination were done. Hb electrophoresis was done in the present study using HYDRASYS ® Electrophoresis Systems from Sebia.

Results

The overall prevalence of SCD in our study was 6.83% the existence of this is found to be greater in the males as compared to females which is in agreement with prevalence across India with more male than female. Thalassemia was prevalent at the rate of 3.96%, sickle cell anemia had a prevalence of 1.98% sickle thalassemia was 0.89%. N = 20 pairs of Parents recognized genetic counseling i.e., with a single child or who wanted further children readily underwent HPLC analysis.

Conclusion

The existence of SCD in our study group is lesser as compared to the South India average. Preventive programs consisting of public education, population screening, genetic counseling, and prenatal diagnosis have been very effective in reducing both rates of β-Thalassemia major. Sickle cell anemia is of prime importance because of its high prevalence, morbimortality and the absence of curative treatments.

Mental health indicators in the later phase of lockdown due to COVID-19 pandemic in healthy youth combined elderly people: a web-based cross-sectional survey

Lockdown was implemented throughout the world in March 2020 to control the spread of covid-19 infection. It affected the mental health of people in various ways. This web-based cross-sectional survey was conducted in the general population of India with an aim to evaluate the mental health of the healthy individuals in the later stage of the lockdown period. Data on socio-demographic factors, anxiety, depression (HADS scale), perceived stress (PSS scale), insomnia (insomnia severity index), subjective psychological feeling of well-being (WHO-5 well-being Index), and attitude towards covid-19 (7-point Likert scale) was collected. Univariate regression analysis and Karl Pearson's correlation were used to analyze the correlation of mental health abnormalities with socio-demographic factors. 119 subjects of mean age of 36.03 ± 18.04 years took part in the study. Their average number of days of stay at home during the lockdown and the average number of days of the lifestyle changes was 49.07 ± 31.92 and 61.39 ± 20.03 days, respectively. Depression, anxiety, stress, and clinical insomnia due to covid-19 were reported in 13.45%, 10.92%, 14.29%, and 11.76% subjects, respectively. There was a significant correlation of depression, anxiety, stress, and WHO-5 well-being score with age, socio-economic status, and the average number of days of the change in lifestyle due to the COVID-19 pandemic (P < 0.05). Therefore, the study concluded that the abnormalities of mental health were less prevalent in the older age group and lower socioeconomic status in the later phase of lockdown.

NAA is a Marker of Disability in Secondary-Progressive MS: A Proton MR Spectroscopic Imaging Study

BACKGROUND AND PURPOSE

The secondary progressive phase of multiple sclerosis is characterised by disability progression due to processes that lead to neurodegeneration. Surrogate markers such as those derived from MRI are beneficial in understanding the pathophysiology that drives disease progression and its relationship to clinical disability. We undertook a 1H-MRS imaging study in a large secondary progressive MS (SPMS) cohort, to examine whether metabolic markers of brain injury are associated with measures of disability, both physical and cognitive.

MATERIALS AND METHODS

A cross-sectional analysis of individuals with secondary-progressive MS was performed in 119 participants. They underwent ¹H-MR spectroscopy to obtain estimated concentrations and ratios to total Cr for total NAA, mIns, Glx, and total Cho in normal-appearing WM and GM. Clinical outcome measures chosen were the following: Paced Auditory Serial Addition Test, Symbol Digit Modalities Test, Nine-Hole Peg Test, Timed 25-foot Walk Test, and the Expanded Disability Status Scale. The relationship between these neurometabolites and clinical disability measures was initially examined using Spearman rank correlations. Significant associations were then further analyzed in multiple regression models adjusting for age, sex, disease duration, T2 lesion load, normalized brain volume, and occurrence of relapses in 2 years preceding study entry.

RESULTS

Significant associations, which were then confirmed by multiple linear regression, were found in normal-appearing WM for total NAA (tNAA)/total Cr (tCr) and the Nine-Hole Peg Test (ρ = 0.23; 95% CI, 0.06-0.40); tNAA and tNAA/tCr and the Paced Auditory Serial Addition Test (ρ = 0.21; 95% CI, 0.03-0.38) (ρ = 0.19; 95% CI, 0.01-0.36); mIns/tCr and the Paced Auditory Serial Addition Test, (ρ = -0.23; 95% CI, -0.39 to -0.05); and in GM for tCho and the Paced Auditory Serial Addition Test (ρ = -0.24; 95% CI, -0.40 to -0.06). No other GM or normal-appearing WM relationships were found with any metabolite, with associations found during initial correlation testing losing significance after multiple linear regression analysis.

CONCLUSIONS

This study suggests that metabolic markers of neuroaxonal integrity and astrogliosis in normal-appearing WM and membrane turnover in GM may act as markers of disability in secondary-progressive MS.

TP1-11 MS-STAT2: a phase 3 trial of high dose simvastatin in secondary progressive multiple sclerosis

Objectives

Disease modifying treatment for secondary progressive multiple sclerosis (SPMS) represents a major unmet need. We outline here the rationale for the MS-STAT2 trial – a phase 3 study of simvastatin in decreasing clinical progression in SPMS. MS-STAT2 will be a landmark study not only for patients with SPMS, but also for the area of drug repurposing and academically led clinical trials as a whole.

Design

Multicentre, double blind, parallel group randomised placebo-controlled trial. It follows the positive outcome from the phase 2 MS-STAT1 trial, which demonstrated a 43% reduction in the annualised rate of brain atrophy compared to placebo.1

Subjects

1180 patients with SPMS with an expanded disability status scale (EDSS) score of 4.0–6.5. Patients need to show evidence of disease progression over the preceding 2 years.

Methods

Subject will be recruited at 28 sites across the UK, and randomised to simvastatin 80 mg or matched placebo and assessed every 6 months over the 3 year trial.

Results

The primary outcome measure is time to 6 month confirmed disability progression, based on change in Expanded Disability Status Scale (EDSS) scores compared to baseline. Secondary outcomes include assessments of cognition, walking, upper limb function and vision. Sub-studies will include advanced imaging outcomes, ocular coherence tomography and fluid biomarkers.

Conclusions

MS-STAT2 is set to be a pivotal trial for SPMS. Recruitment has now commenced and further sites are welcome.
