Efficacy of Bhramari pranayama and Om chanting on asthma control, quality of life, and airway inflammation in asthmatic children: an open-label randomized controlled trial.

OBJECTIVES: To explore the efficacy of combination of Bhramari pranayama and om chanting as an adjunct to standard pharmacological treatment on asthma control, quality of life, pulmonary function, and airway inflammation in asthmatic children. METHODS: Children (n = 110; 8-15 years) with uncontrolled or partly controlled asthma were recruited from the Pediatric Chest Clinic of All India Institute of Medical Sciences, New Delhi. Eligible participants were randomized to either home-based online Bhramari pranayama and om chanting plus standard treatment (YI + ST) group, or standard treatment (ST) alone group. Primary outcome measures were 12-week change in level of asthma symptom control; asthma control questionnaire (ACQ) score, spirometry indices, impulse oscillometry parameters, and pediatric asthma quality of life questionnaire (PAQLQ) score. Secondary outcome was a change in fractional exhaled nitric oxide (FeNO) levels at 12 weeks. Beginning from the enrollment, every participant was evaluated at 0, 2, 6, and 12 weeks. RESULTS: After 12 weeks of intervention, higher proportion (68.2%) of children were found to have controlled asthma symptoms in the YI + ST group as compared to ST group (38.5%) according to per protocol analysis (p = 0.03). When compared to ST group, children in YI + ST group showed significantly lower ACQ score, higher PAQLQ score and reduced FeNO levels. No significant changes were observed for the lung function parameters. CONCLUSION: Children practicing Bhramari pranayama and om chanting for 12 weeks have better asthma symptom control, quality of life, and reduced airway inflammation than those taking standard pharmacotherapy alone.

Effect of Yoga Based Cardiac Rehabilitation on Blood Pressure Variability and Baroreflex Sensitivity: RCT in Patients Post MI.

To assess the effects of 12 weeks Yoga based Cardiac Rehabilitation program on Blood Pressure Variability and Baroreflex Sensitivity in Eighty patients post myocardial infarction. Randomized controlled trial with two parallel groups. A tertiary care institution in India. The Yoga group received 13 hospital-based structured yoga sessions in adjunct to the standard care. Control Group participants received enhanced standard care involving three brief educational sessions on importance of diet and physical activity. Beat to beat arterial pressure variability and baroreflex sensitivity was determined non-invasively. Baseline measurement was done at 3 weeks post Myocardial Infarction. The measurements were repeated at 13th week and at 26th week post MI. There was no significant difference between the groups in time domain indices of SBP variability. At 26th week post MI, after normalization the Low Frequency power increased in the yoga group as compared to the decrease in the standard care group (p = 0.02). Though the High Frequency power increased in both the groups, the magnitude of increase was higher in the standard care group (p = 0.005). However, the total power increased significantly in yoga group with a concurrent decrease in standard care group (p = < 0.001). The SBP All BRS was significantly different between the groups with an increase in the yoga group and a decline in standard care group (p = 0.003) at 13th week. A short-term Yoga based cardiac rehabilitation has additive effects in improving baroreflex sensitivity and dampening blood pressure variability post myocardial infarction in patients under optimal medication.The main trial is registered in Clinical Trials Registry-India (CTRI) (Ref. No: CTRI/2012/02/002408). In addition, CTRI has also been registered for the sub-study. (Ref. No: CTRI/2017/09/009925).

A comprehensive yoga programme for weight reduction in children & adolescents with obesity: A randomized controlled trial.

Background & objectives: Obesity is a rising pandemic in childhood. There is scarcity of evidence on the efficacy of yoga in achieving weight loss in overweight/obese children. The objective of this study was to assess the efficacy of family-based comprehensive yoga intervention in the reduction of body mass index (BMI) in overweight/obese children, in comparison to standard dietary and lifestyle counselling and control group. Methods: This was an open-label randomized controlled study. Children aged 8-15 yr who were overweight or had obesity were randomized to one of the three arms for 18 wk; standard weight management (group 1), yoga with dietary modification (group 2) and control (no intervention; group 3). Reduction in BMI and improvement in physiological, biochemical and psychological parameters from baseline to 18 wk was compared between the three arms. Late follow up was also done at 6-12 months. Results: A total of 165 children with mean±standard deviation (SD) age of 11.6±1.8 yr and mean BMI 26.3±4.2 kg/m2 were enrolled. Outcome analysis at 18 wk was performed for 109 children. Improved diet quality and reduced intake were observed in both intervention arms. The median (IQR) reduction in BMI in standard and yoga arms was similar [-1.4 (-3.1, -0.5) kg/m2 and -1.2 (-2.3, -0.6) kg/m2, respectively], while it increased by +0.3 (-0.3, 0.1) in the control arm. In the yoga arm, mean systolic BP reduced from 118 (10) to 114 (8) mmHg, (P=0.019). In the standard arm, significant improvement in psychological scores was noted. In group 3, the mean fasting glucose increased from 93±10 to 102±12 mg/dl (P<0.001). Interpretation & conclusions: The findings of the present study suggest that yoga in conjunction with dietary modification is equally effective as the standard weight management for BMI reduction in the paediatric age group.

Heteropagus twins: six cases with systematic review and embryological insights.

PURPOSE: Heteropagus twinning (HT) is a rare anomaly. Six new cases along with a systematic review are described. METHODS: Six cases of HT managed at two tertiary care teaching hospitals over the last 26 years are described. A PubMed search with words: Heteropagus AND/ OR parasitic twins from 2001 to 2021 hit 183 articles. 36 were added from non-PubMed sources. Finally, 120 cases including 114 from 69 articles and 6 new cases were analysed. RESULTS: Of the new cases, 2/6 had an antenatal diagnosis. Five were males. 4 autosites had omphaloceles. Split notochord and 2 parasites attached to a single autosite were encountered. 5/6 autosites survived. On systematic review, the most frequent variant seen was rachipagus (n = 50) followed by omphalopagus (n = 46). Limbs were reported in 75 cases. Congenital heart disease was seen in 17/120(14.2%) autosites. Omphalocele and meningomyelocele were the most common extracardiac anomalies in autosites. Weight along with the anatomy and position of heteropagus twins was a better determinant of the mode of delivery than weight alone. Mortality was reported in 12 cases. CONCLUSION: Autosites in HT generally carry a good prognosis, however, final outcome depends mainly on associated major cardiac anomalies. Meticulous antenatal assessment and preoperative planning are of paramount importance. LEVEL OF EVIDENCE: IV.

Predictors of Health-Related Quality of Life in Indians with Metabolic Syndrome Undergoing Randomized Controlled Trial of Yoga-Based Lifestyle Intervention vs Dietary Intervention.

The present study explores the efficacy of 12-week yoga + diet-based lifestyle intervention (YBLI) vs dietary intervention (DI) on health-related quality of life (HRQoL) and identifies the predictors of change in HRQoL in Indians with metabolic syndrome (Met S). Data from the historical randomized controlled trial was used including adults (n = 260, 20-45 years) with Met S. Four domains of HRQoL were measured at baseline, 2 and 12 weeks using WHOQOL-BREF questionnaire. Generalized estimating equation and chi-square test was used to compare 12-week changes in HRQoL domains and proportion of subjects, respectively. Changes in HRQoL were predicted using regression models concerning changes in body mass index (BMI), physical activity, total calorie intake, adiponectin, and superoxide dismutase (SOD) levels. Exploratory mediation analysis was carried out using Baron & Kenny approach. YBLI resulted in a significantly greater increase in the physical domain score of HRQoL than DI. A significantly greater proportion of subjects in YBLI group (71%) showed an increase in physical domain scores compared to DI (51%). A unit change in BMI negatively predicted a unit change in physical, psychological and environmental health. Whereas, a unit change in adiponectin and SOD levels positively predicted a unit change in physical and environmental health. Partial mediation between YBLI intervention and physical HRQoL domain was observed via adiponectin. In conclusion, a 12-week YBLI has a positive and greater effect on HRQoL physical domain score than following DI alone. Changes in BMI, adiponectin, and SOD levels may predict changes in HRQoL domains after lifestyle intervention.

STIM2 interacts with AMPK and regulates calcium-induced AMPK activation.

AMPK is a crucial regulator of energy homeostasis that acts downstream of its upstream kinase liver kinase B1 (LKB1) and calcium/calmodulin-dependent protein kinase 2 (CaMKK2). LKB1 primarily phosphorylates AMPK after energy stress, whereas calcium-mediated activation of AMPK requires CaMKK2, although the regulatory mechanisms of calcium-mediated AMPK activation remain unclear. Using biochemical, microscopic, and genetic approaches, we demonstrate that the stromal interaction molecule (STIM)2, a calcium sensor, acts as a novel regulator of CaMKK2-AMPK signaling. We reveal that STIM2 interacts with AMPK and CaMKK2 and that the increase in intracellular calcium levels promotes AMPK colocalization and interaction with STIM2. We further show that STIM2 deficiency attenuates calcium-induced but not energy stress-induced AMPK activation, possibly by regulating the CaMKK2-AMPK interaction. Together, our results identify a previously unappreciated mechanism that modulates calcium-mediated AMPK activation.-Chauhan, A. S., Liu, X., Jing, J., Lee, H., Yadav, R. K., Liu, J., Zhou, Y., Gan B. STIM2 interacts with AMPK and regulates calcium-induced AMPK activation.

Cytokine and growth factor profile in endometriosis: a multiplex analysis of peritoneal fluid to assess diagnostic utility.

We aimed to assay cytokines and growth factors in peritoneal fluid samples from women with and without endometriosis to understand the inflammatory milieu, and assess their potential diagnostic utility. This cross-sectional study conducted at a tertiary care hospital included 54 women, aged 20-45 years, with regular menstrual history and undergoing diagnostic/therapeutic laparoscopy for infertility and/or pain. Peritoneal fluid samples were collected after insertion of trocar & laparoscope but prior to other surgical intervention. A multiplex immunoassay of 27 cytokines and growth factors was performed. The concentration of FGF2 and CSF3 were significantly lower in women with endometriosis than without endometriosis (p = .043 and .003, respectively). The levels of CCL2 and IL1RN were significantly higher in moderate-severe than in minimal-mild endometriosis (p = .038 and .043, respectively). Phase-specific comparison revealed that in proliferative phase, the levels of CSF2 and CSF3 were lower in women with endometriosis than without the disease (p = .047 and .013, respectively). The ROC curve analysis provided a cutoff value 0.78 and 0.76 for FGF2 and CSF3, respectively. Cytokines and growth factors such as FGF2, CSF3, CSF2, CCL2 and IL1RN seem to contribute to the pathogenesis of endometriosis and may have a potential utility for the diagnosis of endometriosis.

Randomized Controlled Trial of A 12-Week Yoga-Based (Including Diet) Lifestyle vs. Dietary Intervention on Cardio-Metabolic Risk Factors and Continuous Risk Score in Indian Adults with Metabolic Syndrome.

Metabolic syndrome, a prediabetic and precardiovascular pathologic condition that begins early in life, tracks into adulthood and magnifies with age. Randomized controlled trials evaluating efficacy of yoga-based lifestyle vs. dietary intervention on metabolic syndrome are lacking. Here, the efficacy of a 12-week yoga-based lifestyle intervention vs. dietary intervention on cardio-metabolic risk factors and metabolic syndrome risk scores have been assessed in Indian adults with metabolic syndrome. In this two-arm, open label, parallel group, randomized controlled trial, 260 adults (20-45 years) diagnosed with metabolic syndrome as per joint interim statement, 2009 were randomized to yoga-based (including diet) lifestyle or dietary intervention alone (n = 130, each) for 12 weeks. Primary endpoints were the 12-week changes in cardio-metabolic risk factors and metabolic risk scores. The secondary endpoints were the 12-week changes in the proportion of subjects recovered from metabolic syndrome, dietary intake, and physical activity. Intent-to-treat analysis was performed including all the subjects with baseline data with imputed missing data. Treatment × time interaction showed yoga-based lifestyle intervention had a greater treatment effect over dietary intervention by significantly reducing waist circumference, continuous metabolic syndrome z-score, and dietary intake/day while significantly increasing physical activity. High-density lipoprotein cholesterol showed a significantly greater reduction following dietary intervention than yoga-based lifestyle intervention. A significantly greater proportion of subjects recovered from metabolic syndrome in yoga-based lifestyle (45.4%) vs. dietary intervention group (32.3%). A 12-week yoga-based lifestyle intervention is more efficacious than usual dietary intervention in improving cardio-metabolic risk factor and metabolic risk score in Indian adults with metabolic syndrome.

FoxO transcription factors in cancer metabolism.

FoxO transcription factors serve as the central regulator of cellular homeostasis and are tumor suppressors in human cancers. Recent studies have revealed that, besides their classic functions in promoting cell death and inducing cell cycle arrest, FoxOs also regulate cancer metabolism, an emerging hallmark of cancer. In this review, we summarize the regulatory mechanisms employed to control FoxO activities in the context of cancer biology, and discuss FoxO function in metabolism reprogramming in cancer and interaction with other key cancer metabolism pathways. A deeper understanding of FoxOs in cancer metabolism may reveal novel therapeutic opportunities in cancer treatment.

Transmembrane BAX Inhibitor Motif-6 (TMBIM6) protects against cisplatin-induced testicular toxicity.

STUDY QUESTION: Is the Transmembrane BAX Inhibitor Motif-6 (TMBIM6) involved in the molecular mechanism by which cisplatin causes reproductive toxicity? SUMMARY ANSWER: TMBIM6 protects against cisplatin-induced testicular toxicity through up-regulation of heme oxygenase-1 (HO-1),-which maintains the levels of steroidogenic enzymes by decreaseing oxidative stress in the endoplasmic reticulum (ER). WHAT IS KNOWN ALREADY: Testosterone production is highly suppressed as a main complication of cisplatin (cis-diamminedichloroplatinum) anticancer therapy. STUDY DESIGN, SIZE, DURATION: Groups of seven wild type or Tmbim6 KO C57BL/6J mice were given a single i.p., injection of cisplatin (30 mg/kg body wt) and testis and serum were collected 3 days later. Tmbim6-lentivirus-mediated testicular expression-rescued KO mice were analyzed to confirm function was restored. Tmbim6-over expressing TM3 mouse Leydig cells were exposed to cisplatin in vitro. PARTICIPANTS/MATERIALS, SETTING, METHODS: After collection of the specimens serum testosterone level and testicular weight and structure were compared between the groups. Quantitative PCR, immunoblot, and assays for ROS, HO-1 activity and protein disulfide isomerase (PDI) carbonylation were performed. MAIN RESULTS AND THE ROLE OF CHANCE: Phospho protein kinase B (p-Akt), nuclear factor erythroid 2 (NFE2)-related factor 2 (Nrf2), and its downstream gene product HO-1 and the levels of testosterone synthesis-associated enzymes, including steroidogenic acute regulatory protein (StAR), a rate limiting enzyme for testosterone production, were significantly expressed in the presence of Tmbim6 and maintained after cisplatin treament. Excessive post-translational oxidation of protein disulfide isomerase (PDI), altered folding capacitance and ROS accumulation, and ER stress were also decreased in the presence of Tmbim6. Higher levels of ER stress and protein hypercarbonylation were consistently observed in KO testis, compared with WT testis. In the Tmbim6 KO mice, lentivirus-mediated testicular expression of Tmbim6 rescued the above phenotypes. Furthermore, the protective role of Tmbim6 against testicular toxicity was consistently shown in Tmbim6-overexpressing TM3 Leydig cells (testosterone producing cells). We conclude that TMBIM6 protects against cisplatin-induced testicular toxicity by inducing HO-1 and enhancing ER folding capacitance. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: This study was performed using a short, 3-day cisplatin treatment condition. Therefore, the results need to be cautiously interpreted with regard to cisplatin-associated chronic toxicity. Moreover, to determine the clinical relevance of the role of TMBIM6, further studies in testicular cancer are needed. WIDER IMPLICATIONS OF THE FINDINGS: Cisplatin-associated ER stress and redox imbalance might be implicated as toxicity mechanisms associated with anticancer therapy. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by the National Research Foundation of Korea (2015R1A2A1A13001849). The authors have no competing interests to disclose.

Interleukin-6, vitamin D & diabetes risk-factors modified by a short-term yoga-based lifestyle intervention in overweight/obese individuals.

BACKGROUND & OBJECTIVES: Several diabetes prevention programmes have demonstrated a reduction in incidence of diabetes in individuals with prediabetes through weight loss. Short-term yoga-based lifestyle intervention programmes have also been shown to be efficacious in weight loss. This study was undertaken to investigate if interleukin (IL)-6, vitamin D, neopterin, vaspin, and diabetes risk factors can be modified by a short-term yoga-based lifestyle intervention in overweight/obese subjects. METHODS: In this pilot study, 34 overweight/obese [body mass index (BMI) ≥ 23 to <35 kg/m [2] per Asian cut-off values] individuals were enrolled, and received directly supervised intervention for 10 days. Thereafter, they were advised to follow this yoga-based lifestyle at home for one month, and were reassessed for study variables at day 30. RESULTS: There was a reduction from baseline to day 10 in weight ( p <0.001), BMI ( P <0.001), waist/hip-ratio ( P <0.05), blood glucose ( P <0.01), and a significant improvement in lipid profile. There was a decrease in median fasting insulin ( P <0.05), homeostatic model assessment-insulin resistance ( P <0.01), and IL-6 ( Pp <0.05). A non-significant increase in 25-OH-vitamin D, and a decrease in neopterin and vaspin were observed. Twenty subjects returned for follow up assessments. At day 30, weight loss was sustained while systolic blood pressure also showed reduction ( P <0.05). Changes in vitamin D levels were significantly and negatively correlated with changes in weight, BMI and fasting blood glucose, and positively with change in high density lipoprotein. Changes in body weight and BMI significantly and positively correlated with insulin. Changes in IL-6 levels positively and significantly correlated with change in neopterin levels. INTERPRETATION & CONCLUSIONS: The findings showed that IL-6, vitamin D, and diabetes risk factors were favourably modified by a short-term yoga-based lifestyle intervention in obesity. This study also highlighted the challenges in compliance associated with the follow up of subjects following an aggressive supervised intervention of 10 days.

Obesity-related inflammation & cardiovascular disease: efficacy of a yoga-based lifestyle intervention.

Obesity is a global health burden and its prevalence is increasing substantially due to changing lifestyle. Chronic adiposity is associated with metabolic imbalance leading to dyslipidaemia, diabetes, hypertension and cardiovascular diseases (CVD). Adipose tissue acts as an endocrine organ releasing several adipocytokines, and is associated with increased levels of tissue and circulating inflammatory biomolecules causing vascular inflammation and atherogenesis. Further, inflammation is also associated independently with obesity as well as CVD. Keeping this in view, it is possible that a reduction in weight may lead to a decrease in inflammation, resulting in CVD risk reduction, and better management of patients with CVD. Lifestyle intervention has been endorsed by several health authorities in prevention and management of chronic diseases. A yoga-based lifestyle intervention appears to be a promising option in reducing the risk for CVD as well as management of patients with CVD as it is simple to follow and cost-effective with high compliance. The efficacy of such lifestyle intervention programmes is multifaceted, and is achieved via reduction in weight, obesity-related inflammation and stress, thereby culminating into risk reduction towards several chronic diseases including CVD. In this review, the association between obesity-related inflammation and CVD, and the role of yoga-based lifestyle intervention in prevention and management of CVD are discussed.

Distinct peritoneal fluid ghrelin and leptin in infertile women with endometriosis and their correlation with interleukin-6 and vascular endothelial growth factor.

OBJECTIVE: The objective of the present study was to evaluate the levels of leptin, ghrelin, interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) in peritoneal fluid in patients with endometriosis and infertility, and study their correlation. DESIGN AND SETTING: This cross-sectional study included women undergoing diagnostic and/or therapeutic laparoscopy for endometriosis with chief complaint of infertility and/or pain at a tertiary care hospital. Based upon laparoscopic and histopathological findings, patients were categorized as with endometriosis and no endometriosis. Of the 50 patients with infertility (age 23-41 years), 19 had endometriosis while 31 had no endometriosis. The markers were assessed using ELISA kits. RESULTS: The median levels of leptin in patients with endometriosis (10.20 ng/mL) were higher (p = 0.04) and median levels of ghrelin in patients with endometriosis (150.4 pg/mL) were lower (p = 0.037) versus patients with no endometriosis (5.07 ng/mL and 229.6 pg/mL, respectively). The median levels of IL-6 and VEGF in patients with endometriosis were not different between the groups. The correlation analyses showed that leptin levels and IL-6 were positively correlated (p = 0.0001). CONCLUSIONS: The results suggest that ghrelin and leptin might play a key role in pathophysiology of endometriosis, and leptin is associated with inflammation in endometriosis.

High-density lipoprotein cholesterol increases following a short-term yoga-based lifestyle intervention: a non-pharmacological modulation.

OBJECTIVES: The objective of the study was to assess the effect of a brief but comprehensive yoga-based lifestyle intervention on high-density lipoprotein cholesterol (HDL-c). METHODS: This prospective interventional study was performed at the Integral Health Clinic (IHC), an outpatient facility at All India Institute of Medical Sciences, New Delhi, a tertiary health care centre, conducting yoga-based lifestyle intervention programmes for prevention and management of chronic diseases. The study included apparently healthy normal weight, overweight and obese subjects who underwent a pretested 10-day yoga-based programme including asanas (postures), pranayama (breathing exercises), meditation, group discussions, lectures and individualized advice on stress management and healthy diet. The primary outcome measure was change in serum HDL-c at day 10 versus day 0. RESULTS: 238 participants (147 women, 91 men, 38.81±11.40 years) were included in the study. There was a significant increase in HDL-c levels from baseline to day 10 (42.93±5.00 vs 43.52±5.07 mg/dL, P = 0.043). Notably, HDL-c was significantly improved in those for whom the baseline HDL-c levels were lower than the recommended values. Also, there was a reduction in blood pressure, fasting blood glucose, and improvement in other lipid profile variables. CONCLUSION: This yoga-based lifestyle intervention significantly increased HDL-c levels in a short duration of 10 days. This has additional clinical relevance as HDL-c is suggested to be one of the strongest statistically independent predictors of major cardiovascular events.

Age and gender might influence big five factors of personality: a preliminary report in Indian population.

Age and gender are two important physiological variables which might influence the personality of an individual. The influence of age and gender on big five personality domains in Indian population was assessed in this cross-sectional study that included 155 subjects (female = 76, male = 79) aged from 16-75 years. Big five personality factors were evaluated using 60-item NEO-Five Factor Inventory (NEO-FFI) at a single point in time. Among the big five factors of personality, Conscientiousness was positively correlated (r = 0.195; P < 0.05) with age in total study population, and retained the significance (P < 0.05) in men only when analyzed by gender subgroups. Further, age and gender sub-group analysis also showed that Neuroticism was inversely correlated with age in women aged 26-35 years (P < 0.05). Neuroticism and Extraversion showed a positive correlation with age in men aged 36-45 years (P < 0.001 and P < 0.05, respectively). Neuroticism was inversely correlated with age in men aged 46-55 years (P < 0.05). This preliminary report suggested that personality traits might change with age, and is gender-dependent.

Epidemiology of Traumatic Spinal Cord Injury in the Himalayan Range and Sub-Himalayan region: A Retrospective Hospital Data-Based Study.

OBJECTIVE: To compile epidemiological characteristics of traumatic spinal cord injury (TSCI) in the Northern Indian Himalayan regions and Sub-Himalayan planes. METHODS: The present study is a retrospective, cross-sectional descriptive analysis based on hospital data conducted at the Department of Physical Medicine and Rehabilitation and Spine Unit of Trauma Centre in a tertiary care hospital in Uttarakhand, India. People hospitalized at the tertiary care center between August 2018 and November 2021 are included in the study sample. A prestructured proforma was employed for the evaluation, including demographic and epidemiological characteristics. RESULTS: TSCI was found in 167 out of 3,120 trauma patients. The mean age of people with TSCI was 33.5±13.3, with a male-to-female ratio of 2.4:1. Eighty-three participants (49.7%) were from the plains, while the hilly region accounts for 50.3%. People from the plains had a 2.9:1 rural-to-urban ratio, whereas the hilly region had a 6:1 ratio. The overall most prevalent cause was Falls (59.3%), followed by road traffic accidents (RTAs) (35.9%). RTAs (57.2%) were the most common cause of TSCI in the plains' urban regions, while Falls (58.1%) were more common in rural plains. In both urban (66.6%) and rural (65.3%) parts of the hilly region, falls were the most common cause. CONCLUSION: TSCI is more common in young males, especially in rural hilly areas. Falls rather than RTAs are the major cause.

Static and Dynamic Foot Pressure Changes Among Diabetic Patients With and Without Neuropathy: A Comparative Cross-Sectional Study.

INTRODUCTION: Foot ulceration is a frequent diabetic complication with potentially fatal consequences. The pathophysiology of neuropathic ulcers in the diabetic foot is thought to be influenced by abnormal plantar pressures. AIM: This study aimed to compare the maximum peak pressures among diabetic patients with and without neuropathy. The secondary aim was to evaluate the effect of glycemic control on pressure changes in both feet. MATERIALS AND METHODS: The study used 62 diabetic individuals as participants. BMI was calculated, as well as illness duration, hemoglobin A1c, and the existence of neuropathy. Plantar pressure was measured in static (standing) and dynamic (walking/taking a step on the mat) settings for all patients using the BTS P-Walk system. The plantar pressures (kPa) at the five metatarsal regions, the midfoot region, and the medial and lateral heel regions were measured. RESULTS: We found that the dynamic maximum pressures were significantly higher in patients with diabetic neuropathy (DN) compared to diabetics without neuropathy at the first metatarsal and mid-foot area in both feet (p<0.05). We also found significantly elevated plantar pressure in patients with poor glycemic control under the second metatarsal head in the right foot (p<0.05). CONCLUSION: Persons with DN have higher maximum plantar pressures compared to diabetics without neuropathy. Patients with poor glycemic control also have a higher maximum pressure.

Effect of Motor Imagery on Corticomotor Excitability and Pain Status in Rheumatoid Arthritis Patients.

OBJECTIVES: Rheumatoid arthritis (RA) has been defined by the American College of Rheumatology in 1987 as a chronic inflammatory disease characterised by joint swelling, joint tenderness, and destruction of synovial joints leading to severe disability and premature mortality. There is a paucity of literature assessing corticomotor excitability in RA patients. This study aimed to assess the effect of motor imagery on corticomotor excitability and pain status in RA patients. The specific objectives were to study the effect of motor imagery on corticomotor excitability and pain status in RA patients. We also wanted to compare the corticomotor excitability between RA patients with healthy controls. The correlation between the measures of corticomotor excitability and pain status in RA patients has also been done. METHODS: The study was designed as a pilot clinical trial with a case-control design. Forty participants were recruited for the study. Twenty RA patients were recruited from the Department of Rheumatology and Department of Physical Medicine and Rehabilitation (PMR), AIIMS, New Delhi, and 20 healthy controls. Testing was performed at the Pain Research & rTMS Lab, Department of Physiology, AIIMS, New Delhi. The study was approved by the Institute Ethics Committee, AIIMS New Delhi, and registered in the Clinical Trials Registry-India (CTRI). For the subjective assessment of pain, the visual analogue scale (VAS), Short-Form McGill Pain Questionnaire, WHO-Quality of Life Brief questionnaire (WHO-QOL-BREF), and Rheumatoid Arthritis Pain Scale were used. For the objective assessment of pain, hot and cold pain thresholds were assessed using thermo-tactile quantitative sensory testing (QST) using the method of limits and corticomotor excitability using a transcranial magnetic stimulation device. All participants were also asked to perform motor imagery tasks which consisted of a metronome-paced thumb opposition paradigm.  Results: The resting motor threshold (RMT) decreased significantly after motor imagery when compared to the mental calculation group. The amplitude of motor evoked potential (MEP) and QST parameter value was comparable in both the groups before and after motor imagery and mental calculation. RMT was found to be significantly higher whereas MEP values were found to be significantly lower in RA compared to controls. CONCLUSION: We conclude that patients suffering from RA have decreased corticomotor excitability compared to controls. Motor imagery was effective in improving corticomotor excitability in these patients and can be used as rehabilitation in RA to relieve their pain.

Postural Orthostatic Tachycardia Syndrome in Spinal Cord Injury.

Spinal cord injury (SCI), in addition to motor and sensory problems, may also lead to autonomic dysfunction. Postural orthostatic tachycardia syndrome (POTS) is one of them and has often been reported in traumatic brain injuries, multiple sclerosis, and other spinal cord pathologies. However, there is not much data on POTS in SCI even in extensive databases. We present a case of an adolescent female with paraplegia due to traumatic SCI. During her tilt table training, she started having episodes of sinus tachycardia associated with fatigue, dizziness, headache, palpitations, and presyncope with no orthostatic hypotension, after achieving 60 degrees of head tilt. After ruling out the common causes of tachycardia and syncope, a diagnosis of POTS was established. With pharmacologic and non-pharmacological measures, including metoprolol, increased fluid intake, and compression stockings, her symptoms resolved, and she was able to continue rehabilitation.

Difference in Muscle Strength and Functional Outcome in Direct Lateral Approach versus Posterior Approach in Total Hip Arthroplasty: A Prospective Cohort Study.

Background and Purpose: The choice between posterior approach (PA) and direct lateral approach (DLA) for total hip arthroplasty (THA) remains a contentious issue regarding clinical outcome optimization and restoring patient function. Previous studies have evaluated the postsurgical outcomes mostly in the form of Harris hip score (HHS), and the data to objectively measure the postoperative muscle power is scarce. We intend to objectively compare the hip abduction and extension strengths and other functional outcomes with a very simple tool in PA and DLA in the Indian population as most patients do not undergo as intensive rehabilitation in the postoperative period as in the western world. Materials and Methods: A total of 158 patients underwent THA during the study period, of which 48 met inclusion criteria and only 42 completed 6 months follow-up. Patients were evaluated preoperatively, postoperatively at 2 weeks, 6 weeks, 3 months, and 6 months follow-up. At each visit, muscle strength was tested using a customized sling device mounted on a pulling apparatus fitted on the wall, as well as a pain score (VAS), Harris hip score (HHS), and Short Form Survey (SF-36). Results: The study showed statistically significant better hip muscle strength at 2 weeks postoperative for leg press test and 2 weeks as well as 6 weeks postoperative for hip abduction strength in the PA. However, no differences were noted during the 3 or 6 months follow-up period among the DLA and PA. The surgical approach used has no effect on VAS, HHS, or SF-36 scorings. Conclusion: The weak abductor mechanism at 2 and 6 weeks and extension mechanism at 2 weeks in a cohort of DLA in contrast to the PA are seen in the early postoperative period and hence are short-lived muscle weakness. However, there is no effect on VAS, HSS, and SF-36 scores. Therefore, the surgical approach is to be chosen according to the surgeon's expertise.
