Role of calcium &/or vitamin D supplementation in preventing osteoporotic fracture in the elderly: A systematic review & meta-analysis.

Background & objectives: Calcium and vitamin D, separately or in combination are usually prescribed to prevent fragility fractures in elderly population. However, there are conflicting results regarding the ideal dosage and overall efficacy obtained from randomized controlled trials (RCTs) conducted in the past. The objective of this study was to assess the fracture risk with the administration of calcium or vitamin D alone or in combination in elderly population (>60 yr). Methods: PubMed, Cochrane and Embase databases were searched to identify the studies from inception to February 2021 with keywords, 'vitamin D', 'calcium' and 'fracture' to identify RCTs. The trials with comparing vitamin D, calcium or combination with either no medication or placebo were included for final analyses. The data were extracted and the study quality was assessed by two reviewers. The principal outcome measure was fractures around hip joint and secondary outcomes assessed were vertebral and any other fracture. Results: Eighteen RCTs were considered for the final analysis. Neither calcium nor vitamin D supplementation was associated with risk of fractures around hip joint [risk ratio (RR) 1.56; 95% confidence interval (CI), 0.91 to 2.69, I[2]=28%; P=0.11]. In addition, the combined administration of calcium and vitamin D was also not associated with fractures around the hip joint in comparison to either no treatment or placebo. The incidence of vertebral (RR 0.95; 95% CI, 0.82 to 1.10, I[2]=0%; P=0.49) or any other fracture (RR 0.83; 95% CI 0.65 to 1.06, I[2]=0%; P=0.14) was not significantly associated with the administration of calcium and vitamin D either individually or in combination. Further subgroup analysis of the results did not vary with the dosage of calcium or vitamin D, dietary calcium intake sex, or serum 25-hydroxyvitamin D levels. Interpretation & conclusions: The present meta-analysis of RCTs on calcium, vitamin D or a combination of the two in comparison to no treatment or placebo did not support the routine administration protocol of calcium and vitamin D either alone or in combination to lower the risk of fractures in elderly population.

Impact of the 2019 Coronavirus Infectious Disease (COVID-19) pandemic on onset to door time and admissions of new onset acute ischemic stroke in a tertiary care level hospital in North India.

Context: Coronavirus infectious disease (COVID-19) pandemic disrupted the already marginalized healthcare provision in resource limited countries like India. Aims: This study compared onset to door time and temporal trends of admissions to seek medical care in new onset acute ischaemic stroke during the COVID-19 period with a representative pre-COVID-19 period in rural background. Settings and Design: Prospective Cross-sectional study in a tertiary level hospital in North India. Methods and Material: Study included new onset acute ischaemic stroke admitted within first 2 weeks of symptoms onset. Subjects were divided into: Group A - Pre-COVID-19 stroke, Group B - Non-COVID-19 Stroke, and Group C - Stroke, positive for COVID-19. Detailed epidemiological, clinical profile, onset to door time and temporal trends of admissions were recorded. Statistical Analysis Used: Chi square/Fisher's exact test and Independent Samples T test or Mann-Whitney U test were used for categorical and continuous variables. Results: Onset to door time in new onset acute ischaemic stroke was significantly prolonged by 6 h in COVID-19 period (median (interquartile range), 19 (12-27) h) as compared with pre-COVID-19 period. Admissions of new onset acute ischaemic stroke were significantly less in COVID-19 period. Comorbidities and severity of stroke (mean National Institutes of Health Stroke Scale, 20 ± 4) were more during the COVID-19 period. Incidence and mortality of COVID-19 positive new onset acute ischaemic stroke were 0.95% and 38%. Conclusions: Onset to door time in new onset acute ischaemic stroke was significantly prolonged in COVID-19 as compared with pre-COVID-19 period. The admissions were fewer with more severity and comorbidities in COVID-19 period. COVID-19 positive stroke patients had more severity and mortality as compared with non-COVID-19 stroke.

Effects of antihypertensive agents on the quality of life in diabetic hypertensive patients: A prospective study.

Background: Diabetes mellitus is a chronic noncommunicable disease, and hypertension (HT) is the most common comorbidity which affects their quality of life (QoL). Aim: The aim of the study was to assess the effects of antihypertensive agents (viz., amlodipine, ramipril, telmisartan, and ramipril with telmisartan) on the blood pressure (BP) and QoL. Methodology: It was an open-labeled prospective intention-to-treat study done in diabetic hypertensive patients (CTRI/2016/10/007340). Patients were randomly assigned antihypertensive agents, namely, amlodipine, ramipril, telmisartan, and a combination of ramipril with telmisartan (RT) in four groups. They were evaluated for BP, blood sugar level, and QoL at baseline and 24th week. Results: After 24 weeks of therapy, systolic BP (SBP) and diastolic BP (DBP) were significantly reduced in all groups. In amlodipine, there was a mean percentage fall of SBP by 15.85% (confidence interval [CI]: 21.38-28.13) and DBP by 11.22% (CI: 8.41-12.70); in ramipril - 14.4% (CI: 18.61-25.15) and 12.4% (CI 8.88-13.99); telmisartan - 18.4% (CI: 24.89-10.79) and 14.6% (CI 10.79-16.24); and in RT group, SBP 17.7% (CI: 23.38-29.18) and DBP 12.4% (CI: 9.05-13.02). QoL score increased by 30.56% (CI: 14.30-10.90), 30.94% (CI: 14.21-10.68), 28.07% (CI: 14.89-11.20), and 28.84% (CI: 15.49-11.77), in respective groups (P < 0.0001, each). However, they were nonsignificant between the study groups (P > 0.05). Conclusion: Amlodipine, ramipril, telmisartan, and a combination of RT are equally effective to improve BP and QoL among diabetic hypertensive patients. However, amlodipine and telmisartan lacked in dry cough and more tolerable than the ramipril and RT therapy. Henceforth, amlodipine and telmisartan are better choice to control HT among DM patients.

Tranexamic Acid in Melasma: Comparative Evaluation of Therapeutic Efficacy of Oral Tranexamic Acid versus Its Transepidermal Administration.

Background: Melasma is a common disorder of hyperpigmentation mainly affecting the face. It is difficult to treat and is a cause for great cosmetic concern for the patient. So, we did this research to compare the therapeutic efficacy of tranexamic acid (TXA) through oral route versus its transepidermal administration with a dermaroller in melasma. Materials and Methods: This was a hospital-based, interventional study carried over a span of 1 year on 40 patients with facial melasma. The enrolled patients were randomly divided into 2 groups of 20 patients each. Group A patients received oral tablet TXA in a dose of 250 mg twice daily for 12 weeks and Group B patients were given TXA solution transepidermally into the melasma lesions using a dermaroller at 2 weekly interval for 12 weeks. Thereafter, all patients were followed up for improvement in Melasma Area and Severity Index (MASI) score, adverse effects and relapse at 4 weekly intervals till 24 weeks. All the patients were evaluated for therapeutic outcome both objectively (by MASI) and photographically at 4, 8, 12, 18, and 24 weeks. Grading of improvement was done by assessing percentage reduction in MASI score. Results: Majority of the patients, 24 (60%) in our study had centrofacial pattern of melasma followed by malar pattern seen in 16 (40%) patients. The baseline MASI score was 11.98 (± 5.47) in Group A and 12.13 (± 3.16) in Group B. The mean MASI score in Group A at the end of 4, 8, 12, 18, and 24 weeks was 9.75 (±4.83), 6.09 (±3.64), 4.21 (±2.48), 2.56 (±1.95), and 3.10 (±3.38) while these values were 9.73 (±3.32), 6.06 (±2.75), 4.55 (±1.89), 2.94 (±1.36), and 3.09 (±1.32) for Group B. At the end of 24 weeks follow-up period, good (51%-75% improvement) and very good (>75% improvement) response occurred in 5 (25%) and 14 (70%) patients in Group A and 11 (55%) and 9 (45%) patients in Group B, respectively. However, the final reduction in MASI score was similar in both the groups. Relapse was uncommon and occurred at 24 weeks in 1 patient from Group A. Limitation: The major limitation was small sample size due to time limitation and long follow-up period. Conclusions: Oral and transepidermal TXA appear equally effective suggesting that the efficacy of TXA is perhaps independent of its route of administration. Oral therapy is convenient for the patient. Transepidermal therapy of TXA has the advantage of local action, hence systemic side effects are avoided, but it is slightly painful and the time period between consecutive microneedling sessions is left to the prerogative of the treating doctor, hence a proper quantification is lacking. Moreover, scheduling of maintenance sessions is necessary as melasma is prone for recurrence.

Clinicoradiological profile and outcome of cavernous sinus syndrome with coronavirus disease-2019-associated rhino-orbito-cerebral mucormycosis.

Objective: With coronavirus disease 2019 (COVID-19) pandemic across the world, there had been an exponential increase in rhino-orbito-cerebral mucormycosis (ROCM). Extension of infection to cavernous sinus leads to cavernous sinus syndrome (CSS). This study aims to describe incidence, clinicoradiological profile, and outcome of CSS positive along with comparative analysis of CSS negative COVID-19-associated ROCM. Material and Method: This was a prospective and observational study conducted from May 1, 2021, to July 31, 2021. Subjects included ROCM with active or recovered COVID-19 (past 6 weeks) and were categorized and staged. CSS was defined as involvement of two or more of third, fourth, fifth, or sixth cranial nerve with one each direct and indirect qualitative neuroradiological features. Clinicoradiological features of CSS-positive and negative COVID-19-associated ROCM groups were compared. Results: Incidence of CSS with COVID-19-associated ROCM was 28%. Mean age of subjects was 44 ± 15 years with 60% being males and 73% were proven ROCM. Significant differences seen across the CSS-positive and negative groups were ocular, nasal, and cerebral findings including eyelid and periocular discoloration, ptosis, proptosis, ophthalmoplegia, nasal discharge, mucosal inflammation, and fever. Oculomotor, trochlear, and abducens nerves were significantly involved more in CSS-positive group. Significant radiological findings across two groups included indirect features in orbit, nose, and paranasal sinuses along with direct features in cavernous sinus. Surgical intervention was more common in CSS-positive group. Mortality in CSS-positive group at 8-24 weeks was 13 and 27%, respectively. Conclusion: Extension of ROCM to CSS was more common in young males in advanced stages of proven ROCM with concurrent COVID-19. CSS-positive group had significant difference in clinicoradiological features involving orbit, nose, paranasal sinuses, and central nervous system as compared to CSS-negative group. This study highlights the need to develop an objective scoring system considering clinical and radiological features for diagnosis of CSS with COVID-19-associated ROCM.

Prevalence of fatty liver in metabolic syndrome.

BACKGROUND: In Western world, non-alcohlic fatty liver disease (NAFLD) is considered to be the commonest liver problem, and it is being recognised as a major cause of liver-related morbidity and mortality. As the prevalence of overweight/obesity and metabolic syndrome increases, NASH may become one of the more common causes of end stage liver disease and hepatocellular carcinoma. But much information is not available in this association. So an attempt has been made to correlate both. AIMS: The aims of this study are: 1. to study the prevalence of non-alcoholic fatty liver in metabolic syndrome; and 2. to study the correlation between the non-alcoholic fatty liver and metabolic syndrome along with its individual components. MATERIALS AND METHODS: The study was an observational and analytical study of patients attending OPD and indoor patients of the Department of Medicine, G.G.S. Medical College and Hospital Faridkot. In total, 100 patients diagnosed as metabolic syndrome according to the NCEP ATP III criteria were subjected to ultrasonography; age and sex matched 100 controls were also taken; and the relationship between metabolic syndrome and NAFLD was studied. RESULTS: In total, 73% cases of metabolic syndrome according to NCEP ATPIII were having fatty liver, while in controls 38% persons were having fatty liver which is statistically significant. CONCLUSIONS: Fatty liver was found to be highly prevalent in metabolic syndrome, and the early detection of fatty liver can help in modifying the disease course and delaying more serious complications like cirrhosis of liver and hepatocellular carcinoma.

Comparative Evaluation of Therapeutic Efficacy of Intralesional Injection of Triamcinolone Acetonide versus Intralesional Autologous Platelet-rich Plasma Injection in Alopecia Areata.

CONTEXT: Alopecia areata is a chronic non-scarring alopecia that involves scalp and/or body. Corticosteroids are the most popular drugs for its treatment. AIM: The aim of the study was to evaluate the therapeutic efficacy of intralesional injection of triamcinolone acetonide and platelet-rich plasma (PRP) in alopecia areata and to compare the efficacy of these modalities in alopecia areata. SETTINGS AND DESIGN: This was a randomized controlled comparative study. SUBJECTS AND METHODS: Forty patients were enrolled from the outpatient department and divided into two groups of 20 patients each. Group A and B randomly received intradermal triamcinolone acetonide suspension (10 mg/mL) and PRP, respectively, into the lesion using an insulin syringe in multiple 0.1 mL injections 1cm apart. The injections were repeated every 3 weeks till 12 weeks. The patients were evaluated by Severity of Alopecia Tool (SALT) score and photographically every 3 weeks till the end of 12 weeks and then at the end of 6 months. Statistical analysis used descriptive analysis along with Pearson chi-square test or Fisher exact test, paired samples, and independent samples t test or their nonparametric analogs for continuous variables. RESULTS: The reduction in SALT score at each visit with respect to baseline was greater in the triamcinolone group as compared to PRP group. This signifies greater effect of triamcinolone in alopecia areata. Around 50% patients in triamcinolone group and 5% patients in PRP group showed grade V improvement. Pain during intralesional injection was higher in the PRP group. CONCLUSION: Both intralesional triamcinolone and PRP were found to be efficacious in alopecia areata but the latter produced lesser improvement.

Meta-Analysis of Randomized Controlled Trials Involving Anterior Shoulder Instability.

BACKGROUND: Arthroscopic repair is gaining popularity over open repair for the treatment of bankart lesions. The study aims to evaluate the outcome of arthroscopic repair with open repair in randomised controlled trials conducted comparing the two techniques. METHODS: We searched the Cochrane library, PubMed and EMBASE up to December 2017 for clinical trials comparing the outcomes of arthroscopic bankart repair with open bankart repair. We used fixed or random effects model depending upon heterogenicity. Dichotomous variables were presented as Risk Ratios (RRs) with 95% Confidence Intervals (CIs), and continuous data were measured as measured differences with 95% CIs. RESULT: Five studies were included, with sample size ranging from 42 to 196. Fixed effect analysis showed that the shoulder was more stable in open repair (RR=0.897, 95% CI: 0.821 to 0.980, P= 0.94) but the loss of external rotation at shoulder joint was also higher in those had open repair (RR=0.325, SMD=-0.411, 95% CI: -1.229 to 0.407). The functional outcome assessed by Rowe score was better in open repair (P=0.325). The operative time was lesser in arthroscopic repair but was not statistically significant (P=0.085). CONCLUSION: Our meta-analysis showed that the use of arthroscopic repair though offers better shoulder movement but the open repair is superior in terms of shoulder stability.

Correlation of Parathyroid Hormone Levels with Mineral Status in End-stage Renal Disease Patients.

Parathyroid hormone (PTH) is the main regulator of calcium, phosphate, magnesium, sodium, and potassium homeostasis. Therefore, this study was conducted to evaluate the relationship between PTH and aforementioned minerals in end-stage renal disease (ESRD) patients. AIM: The aim of this study was to estimate serum intact parathormone (iPTH) and other biochemical parameters in ESRD patients and to find correlation between serum iPTH and biochemical parameters in the study group. RESULTS: This cross-sectional study included 60 clinically diagnosed patients of ESRD of age (>18 years), either sex. Disordered mineral metabolism is common complications of ESRD patients. The mean value of calcium, phosphorus, and magnesium was 7.90 ± 1.16 mg/dL, 6.44 ± 1.72 mg/dL, and 2.57 ± 0.62 mg/dL, respectively, indicating hypocalcemia, hyperphosphatemia, and hypermagnesemia in ESRD patients. To compensate the deranged mineral status, increased levels of PTH were seen in ESRD patients with mean value of 173.93 ± 62.62 pg/mL. There was a statistically significant positive correlation found between PTH and S. creatinine (P ≤ 0.001; r = 0.596), whereas the statistically significant negative correlation found between PTH and eGFR (P ≤ 0.001; r = -0.525). A significant positive correlation found between PTH and phosphorous (P = 0.003; r = 0.378) and potassium (P ≤ 0.001; r = 0.421). On the other hand, significant negative correlation found with calcium (P ≤ 0.001; r = -0.805) and corrected calcium (P = <0.001; r = -0.769). But nonsignificant association was found with magnesium, sodium, and calcium × phosphorous (P > 0.05). CONCLUSION: It was concluded that PTH is playing crucial role in mineral metabolism; it should be frequently assessed in order to prevent any untoward mineral decompensation and to prevent complications like bone disease and extra skeletal calcification, and decrease cardiac disease risk in ESRD patients.
