Anaemia of chronic disease among pulmonary tuberculosis patients is associated with inflammatory marker at the start of intensive phase.

Background: Tuberculosis (TB) disrupts iron balance through systemic inflammation. Pulmonary tuberculosis (PTB) is linked to diverse anaemia types, necessitating intricate haematological and biochemical assessments for diagnosis. This study aims to describe the prevalence of anaemia of chronic disease (ACD), iron deficiency anaemia (IDA) among PTB patients and factors associated with these types of anaemia. Methods: A cross-sectional analysis was conducted from community-based cohort study involving sputum-positive PTB patients from 2018 to 2020 in urban Puducherry. Participants were enrolled from 10 primary health centres within 2 weeks of initiating anti-tubercular treatment (ATT). Blood samples were collected for assessing haematological and biochemical parameters. The sTfR/log ferritin ratio was used to distinguish between ACD and IDA. Data were captured using Epicollect5 and analysed using STATA V14. Result: Of the 176 PTB patients included, 63.07% (111/176) had anaemia, with ACD being the predominant type (84.6%, 94/111). The C-reactive protein (CRP) levels were higher among the anaemic group [40.77 (16.66-58.51) mg/dl vs 24.65 (14.23-47.26) mg/dl] and higher among the ACD as compared to IDA [46.9 (22.3-61.2) vs 20.8 (13.0-39.1) mg/dl]. Undernourished [adjusted prevalence ratio (APR) =3.43; confidence interval (CI): 1.21-9.69] and patients having low risk of dependence on tobacco [APR = 1.52; CI: 1.10-2.11] had higher risk of ACD. Female patients had higher risk of IDA [APR = 4.95, P < 0.01]. Conclusion: The largest proportion of the PTB participants with anaemia had ACD. Acute-phase reactant and inflammatory marker are increased among newly diagnosed new sputum smear-positive (NSP) PTB participants at the start of ATT. Addressing inflammation is needed for combating anaemia in PTB patients.

Influence of sleep disturbance, depression, anxiety, and stress on quality of life in people with epilepsy.

OBJECTIVES: We assessed the quality of life, sleep, depression, anxiety, and stress in people with pharmacoresistant epilepsy (PRE) and newly diagnosed epilepsy (NDE). We also assessed the influence of sleep, depression, anxiety, and stress on the quality of life (QOL) and the complex association between these factors. METHODS: We recruited 80 PRE and 70 NDE people attending the epilepsy clinic. We assessed QOL, sleep quality, daytime sleepiness, and mood using the quality of life in epilepsy-31 inventory (QOLIE-31), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), and depression anxiety stress scale (DASS-21). We compared the results between the two groups of epilepsy populations. We performed univariate and multivariate linear regression to determine the factors affecting the QOLIE-31 total score. We applied Spearman's rank correlation to find the interrelationship between variables influencing QOL. RESULTS: We found significantly lower QOLIE-31 total scores (p = .001) in PRE compared to NDE. The PSQI and ESS did not differ significantly between the PRE and NDE groups. Anxiety (p = .002) and stress (p = .003) scores were significantly higher in PRE than in NDE. QOLIE-31 total scores showed a negative correlation with PSQI as well as symptoms of depression, anxiety, and stress scores in both groups. Multiple linear regression analysis revealed depression as a major factor influencing the QOLIE-31 total score in PRE (p = .001) and NDE (p = .003). We found significant complex associations between PSQI, depression, anxiety, stress, and QOLIE total scores in both groups. SIGNIFICANCE: The QOL is poorer for people with PRE than for those with NDE. Depression is a major determinant of QOL in PWE. These factors need to be considered to improve the QOL in epilepsy.

Comparison of P300 Cognitive-evoked Potentials and Visual and Auditory Reaction Time in Stage 5 Chronic Kidney Disease Patients on Different Treatment Modalities.

Patients with chronic kidney disease (CKD) are at a higher risk of cognitive impairment. Poor quality of life and decreased compliance are frequently observed with cognitive decline among CKD patients. Cognitive impairment among Stage 5 CKD patients varies with different modalities of treatment, and contradicting results have been reported. Fifty-four medically stable Stage 5 CKD patients undergoing different modalities of treatment were recruited: Patients with Stage 5 CKD on maintenance hemodialysis (HD) (n = 18), continuous ambulatory peritoneal dialysis (CAPD) (n = 18), and conservative management (CM) (n = 18). Eighteen apparently healthy participants were recruited as a control group. The cognitive functions assessed were P300 event- related potential, auditory and visual reaction times (VRTs). Kidney function was assessed by serum creatinine and estimated glomerular filtration rate. Creatinine levels were significantly higher in all three treatment groups compared with the control group. Multivariate analysis revealed a significant association between the CKD groups (n = 54) and the parameters of cognitive function. P300 latency was prolonged in all treatment groups compared with the control group and was significantly prolonged in patients on CM compared with HD and CAPD patients. The VRT of CM patients was found to be significantly higher compared with the control group. The auditory reaction time was significantly prolonged in all treatment groups compared with the control group and in the CM group compared with the CAPD group. Cognitive function was more affected in Stage 5 CKD patients on CM compared with patients undergoing HD or CAPD.

Role of specific nutritional biomarkers in predicting post-operative complications among patients undergoing elective abdominal surgery.

PURPOSE: Nutritional biomarkers like serum prealbumin, transferrin, retinol-binding protein (RBP), C-reactive protein (CRP), leptin, and insulin-like growth factor 1 (IGF1) have the inherent ability to diagnose undernutrition objectively before it is clinically manifested. The primary objective of the study was to evaluate the diagnostic efficacy of the specific nutritional biomarkers in predicting post-operative complications. METHODS: A prospective cohort study was conducted in the department of surgery and included all patients aged 18 years and above who underwent elective abdominal surgery. Demographic details and clinical and surgical details were documented from the case records. Nutritional biomarker assay was done at admission. The post-operative complications occurring until discharge were graded using the Clavien-Dindo classification. The diagnostic accuracy of the specific nutritional biomarkers in predicting post-operative complications was assessed. RESULTS: A total of 320 patients were included in the study. Of these, 126 (39.38%) developed post-operative complications. Major complications accounted for 19.05% of the complications, while 80.95% were minor complications. Patients with blood prealbumin level less than 17.287 mg/dL had a higher incidence of complications (p < 0.001). Serum transferrin levels less than 168.04 mg/dL and IGF1 levels less than < 44.51 ng/ml showed increased incidence of complications (p < 0.001). The AUC was found to be the highest for serum IGF1 with 0.7782. Sensitivity was equally high for IGF1 and serum transferrin, with 76.98% for the former and 76.19% for the latter. CONCLUSION: Specific nutritional biomarkers, like serum prealbumin and transferrin, were efficient in predicting postoperative complications of patients before undergoing elective abdominal surgeries even after adjusting for confounders. This can facilitate preoperative corrective measures to lower the overall postoperative complications.

Association of rs2073618 polymorphism and osteoprotegerin levels with hypertension and cardiovascular risks in patients with type 2 diabetes mellitus.

There are reports of link of osteoprotegerin (OPG) gene polymorphism to type-2 diabetes (T2D) and hypertension (HTN). The objective of the study was to assess the allele frequency of OPG (rs2073618) gene polymorphism and its association with heart rate variability (HRV) and blood pressure variability profile as CVD risks in diabetes mellitus patients with hypertension undergoing treatment. T2D patients on treatment without hypertension (n = 172), with hypertension (n = 177) and 191 healthy volunteers were recruited for the study. Their blood pressure variability including baroreflex sensitivity (BRS), heart rate variability (HRV), OPG, insulin, lipid profile, receptor-activator for NFkB (RANK), receptor-activator for NFkB-Ligand (RANKL), and tumor necrosis factor-α (TNF-α) were estimated. Allele frequency of OPG (rs2073618) gene polymorphism was assessed from the DNA samples. BRS and HRV indices were decreased, and RANKL/OPG and TNF-α were increased in T2D and T2D + HTN groups, respectively compared to healthy control group. The reduction in BRS was contributed by increased inflammation and reduced SDNN of HRV in GG genotype in T2D + HTN. In GG + GC subgroup, it was additionally contributed by rise in RANKL/OPG level (ß - 0.219; p 0.008). Presence of mutant GG genotype contributed to the risk of hypertension among T2D patients (OR 3.004) as well as in general population (OR 2.79). It was concluded that CV risks are more in T2D patients with HTN expressing OPG rs2073618 gene polymorphism.

Skeletal muscle injury in COVID infection: Frequency and patterns.

INTRODUCTION/AIMS: Little is known about skeletal muscle injury with coronavirus disease 2019 (COVID-19). We estimate the frequency and explore the patterns of skeletal muscle injury in acute COVID-19. METHODS: A cohort of COVID patients with mild to moderate symptoms were evaluated in a COVID-designated hospital between May and December 2021 and followed for 2 weeks. Skeletal muscle injury was assessed according to creatine kinase (CK) levels, Manual Muscle Test-8 (MMT-8) score, and the Health Assessment Questionnaire (HAQ) score. Injury was defined as CK >200 IU/L with an MMT-8 score < 76. The association between such injury and severity and outcomes were evaluated using cross-tabulations. RESULTS: Two hundred fifty participants with a mean age of 50.2 years (SD: 17.2) were included. One hundred nine (43.6%) were women; 84 (34%) developed severe disease. Median CK levels were 91 IU/L (IQR 56-181). [Correction added on 17 November 2023, after first online publication: In the preceding sentence, the IQR was corrected from '56,181'.] Patients with weakness on the MMT-8 (n = 247, 98.8%) and disability on the HAQ (n = 107; 42.8%) were common. Neck flexor muscles were prominently affected. Skeletal muscle injury was seen in 22.4% (95% CI: 17.4-28.1). There was no significant association between skeletal muscle injury and maximal severity of illness or short-term outcomes. Disability increased over 14 days in most survivors (n = 172, 72.3%) and this was not seen in those with mild disease (OR: 0.4, 95% CI: 0.22-0.70). DISCUSSION: Skeletal muscle injury appears to be common in people presenting with mild to moderate COVID infection.

Predictors of Change in the Anemia Status Among Pulmonary Tuberculosis Patients Following Anti-tuberculosis Treatment in Puducherry, India.

Background Pulmonary tuberculosis (PTB) is commonly associated with reversible peripheral blood abnormalities. The evolution of tuberculosis (TB)-associated anemia with anti-tuberculosis treatment (ATT) has not been well elucidated. This study aimed to compare the hematological profiles at the start and end of the ATT among new sputum smear-positive (NSP) PTB patients in Puducherry, India. Methods A prospective cohort study was conducted in the 10 urban primary health centers of Puducherry from 2017 to 2020. All the NSP PTB participants aged ≥18 years registered under the National Tuberculosis Elimination Program (NTEP) were contacted within two weeks of the start of the ATT. All eligible participants were enrolled, and they were followed up till the end of ATT (180 days). Hematological profiles and anthropometric measurements were compared at the start and end of the ATT. Binomial logistic regression analysis was used to assess the predictors of changes in the anemia status at the start and end of the ATT. Results Out of 176 NSP PTB participants, 145 were followed up after treatment. Initially, 63% (111/176) patients had anemia, which decreased to 44% (64/145) by the end of treatment. The risk factors for a negative change in hemoglobin levels were female gender, below poverty level, underweight, and reduced iron intake. The adjusted risk ratios (ARRs) were 1.53 (1.24-1.88), 1.18 (1.01-1.38), 1.29 (1.02-1.64), and 1.26 (1.05-1.51),respectively. Conclusion ATT may lead to the resolution of TB-associated anemia. Moreover, female gender, possession of a red ration card, being underweight, and reduced iron intake were identified as risk factors for negative changes in hemoglobin levels during treatment.

Inflammation and decreased cardiovagal modulation are linked to stress and depression at 36th week of pregnancy in gestational diabetes mellitus.

Stress and depression have been reported in gestational diabetes mellitus (GDM). Though inflammation and oxidative stress are associated with depression, there are no reports of link of cardiometabolic risks (CMR) to stress and depression in GDM. Normal pregnant women (control group, n = 164) and women with GDM (study group, n = 176) at 36th week of gestation were recruited for the study. Blood pressure (BP), body composition, heart rate variability (HRV), glycated hemoglobin (HbA1C), markers of insulin resistance, oxidative stress, inflammation and endothelial dysfunction, were assessed. Perceived stress score (PSS), quality of life (QoL) scale, Indian diabetic risk score (IDRS) and Edinburg postnatal depression score (EPDS) were assessed. Association of potential contributors to PSS and EDPS were assessed by correlation and regression analyses. There was significant increase in PSS, EPDS, IDRS scores, HbA1C, malondialdehyde (MDA) (oxidative stress marker) and high-sensitive C-reactive protein and interleukin-6 (inflammatory markers), and significant decrease in total power (TP) of HRV (marker of cardiovagal modulation), QoL and nitric oxide (endothelial dysfunction marker) in study group compared to control group. Though many cardiometabolic risk parameters were correlated with PSS and EPDS, the significant independent association was observed for TP, HbA1C, MDA and interleukin-6. However, interleukin-6 had maximum contribution to PSS (ß = 0.550, p < 0.001) and EPDS (ß = 0.393, p < 0.001) as demonstrated by multiple regression analysis. Inflammation, oxidative stress, glycation status and decreased cardiovagal modulation are associated with stress and depression at 36th week of gestation in GDM.

Diagnostic Utility of NLR, PLR and MLR in Early Diagnosis of Gastric Cancer: an Analytical Cross-Sectional Study.

PURPOSE: Inflammatory markers such as neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR) are linked with the pathogenesis of gastric cancer (GC). However, the clinical significance of the combination of these markers is unclear. Hence, this study was carried out to determine the individual and combined diagnostic accuracy of NLR, PLR and MLR among patients with GC. METHODS: In this prospective, cross-sectional study, patients were recruited into three groups, GC, precancerous lesions and age and gender-matched controls. The primary outcome was to determine the diagnostic accuracy of inflammatory markers in the diagnosis of GC. The secondary outcome was to determine the correlation of inflammatory markers with the stage of gastric cancer, nodal involvement and metastasis. RESULTS: A total of 228 patients, 76 in each group, were enrolled. The cut-off value of NLR, PLR and MLR were 2.23, 146.8 and 0.26, respectively, for the diagnosis of GC. The diagnostic abilities of NLR, PLR and MLR were significantly high at 79, 75 and 68.4, respectively, to predict GC compared to precancerous and control groups. All the models of inflammatory markers showed excellent discrimination between GC and the controls with an AUC > 0.7. The models also showed acceptable discrimination between GC and the precancerous lesion group with AUC between 0.65 and 0.70. No significant difference was found in correlating inflammatory markers with clinicopathological features. CONCLUSION: The discrimination capacity of the inflammatory markers could be used as screening biomarkers in diagnosing GC, even in its early stages.

Effect of Synbiotics in Reducing the Systemic Inflammatory Response and Septic Complications in Moderately Severe and Severe Acute Pancreatitis: A Prospective Parallel-Arm Double-Blind Randomized Trial.

AIM: This study aimed at evaluating the efficacy of synbiotics in reducing septic complications in moderately severe and severe acute pancreatitis. METHODS: This was a prospective, parallel-arm, double-blinded superiority randomized control study. All patients with moderately severe and severe acute pancreatitis were included in the study. Acute on chronic pancreatitis, pancreatitis due to trauma, ERCP and malignancy were excluded. 1 g of synbiotic containing both pre- and probiotics was administered to the cases twice a day for 14 days and a similar-looking placebo to controls. Patients were followed for 90 days. Primary outcomes were reduction of septic complications and inflammatory marker levels. Secondary outcomes were mortality, non-septic morbidity, length of hospitalization (LOH) and need for intervention. RESULTS: A total of 86 patients were randomized to 43 in each arm. Demographic profile and severity of pancreatitis were comparable. There was no significant difference in septic complications between the groups (59% vs. 64%; p 0.59). Total leucocyte and neutrophil counts showed a significant reduction in the first 7 days (p = 0.01 and 0.05). No significant difference was seen in other inflammatory markers. There was a significant reduction in the LOH (10 vs. 7; p = 0.02). Non-septic morbidity (41% vs. 62.2%; p 0.06) and length of ICU stay (3 vs. 2; p 0.06) had a trend towards significance. The need for intervention and mortality was comparable. CONCLUSION: Synbiotics did not significantly reduce the septic complications in patients with moderately severe and severe acute pancreatitis; however, they significantly reduced the LOH. There was no reduction in mortality and need for intervention. Clinical Trials Registry of India Number: CTRI/2018/03/012597.

Cardiovascular autonomic function and baroreflex sensitivity in drug-resistant temporal lobe epilepsy.

OBJECTIVE: Temporal lobe epilepsy (TLE) is often associated with autonomic manifestations. Sudden unexpected death in epilepsy (SUDEP) is a leading cause of mortality in epilepsy. Cardiac disturbances and autonomic dysfunction are the potential mechanisms behind SUDEP. Though heart rate variability (HRV) and autonomic function tests are well studied in drug-resistant temporal lobe epilepsy, there is a paucity of data on baroreflex sensitivity (BRS), a better marker of cardiac mortality in this population. We aimed to study the interictal cardiac autonomic function and BRS in people living with drug-resistant temporal lobe epilepsy compared to healthy controls. MATERIALS AND METHODS: Thirty drug-resistant temporal lobe epilepsy (TLE) individuals and thirty healthy volunteers were recruited. Heart rate variability at rest, heart rate and blood pressure (BP) at rest, during deep breathing, postural change, BP response to isometric handgrip exercise, and baroreflex sensitivity were recorded in all study participants. The results were analyzed and compared between the two groups. RESULTS: Compared to controls, the resting heart rate, HRV, parasympathetic reactivity test, and BRS significantly differed in people living with drug-resistant TLE. Time-domain indices including SDNN (p < 0.001), RMSSD (p < 0.001), NN50 (p < 0.001), and pNN50 (p < 0.001) were significantly reduced in the patients compared to controls. In frequency-domain indices, the total power was reduced (p < 0.001) in drug-resistant TLE. The parasympathetic reactivity such as changes in heart rate during deep breathing (E: I) (p < 0.02) and postural change (30:15) (p < 0.005) were significantly reduced in the patients. Baroreflex sensitivity was also significantly reduced in the drug-resistant TLE group (p < 0.001). CONCLUSION: The present study findings are suggestive of parasympathetic dysfunction in drug-resistant TLE. Reduced HRV and BRS may increase the risk of SUDEP in people living with epilepsy.

Hypertension attenuates the link of osteoprotegerin to reduced baroreflex sensitivity in type 2 diabetes mellitus patients on oral antidiabetic and antihypertensive therapy - a cross sectional study.

PURPOSE: Decreased baroreflex sensitivity (BRS) has been shown to be a marker of cardiovascular (CV) risk. In the present study, the difference in CV risk biomarkers in type 2 diabetes (T2D) patients receiving oral antidiabetic drugs (OAD) with and without hypertension has been assessed. MATERIALS AND METHODS: Ninety-two T2D patients on OAD without hypertension (control group) and eighty-eight diabetic patients with hypertension on OAD and antihypertensive drugs (test group) matched for age, gender, body mass index, serum glucose, glycated haemoglobin, and duration of the disease were recruited for the study. Their blood pressure (BP) variability including BRS, heart rate variability (HRV), insulin, lipid profile, osteoprotegerin (OPG), and tumor necrosis factor-α (TNF-α) were estimated. The association of various factors with BRS was assessed by Spearman correlation and multiple regression analysis. RESULTS: BRS was decreased (13.90 ± 5.27 vs 6.76 ± 4.58), HRV sympathetic indices [LFnu, LF-HF ratio (1.30 ± 0.49 vs 1.93 ± 0.62)], HOMA-IR, atherogenic index of plasma (AIP), OPG (223.08 ± 103.86 vs 287.60 ± 121.36) and TNF-α were increased, and parasympathetic indices [TP (1012.90 ± 316.18 vs 625.88 ± 229.84), RMSSD, SDNN, NN50, pNN50] were decreased in the test group compared to control group. In control group, parasympathetic indices, AIP, OPG, and TNF-α had a significant correlation and OPG had an independent association (ß - 0.344; p 0.004) with BRS. In test group, BP, LF-HF ratio, parasympathetic indices, AIP, OPG, and TNF-α had significant correlation, and TNF-α alone (ß - 0.297; p 0.022) had an independent contribution to decreased BRS. CONCLUSION: Despite antidiabetic and antihypertensive treatments, T2D patients with hypertension had more cardiometabolic risks in comparison to normotensive T2D patients. Inflammation could be the inciting factor for rise in BP and decrease in BRS (CV risk) in hypertensive T2D patients. Hypertension in diabetes could attenuate the link of OPG to the reduction in BRS. Reduction in BRS could be a physiological marker of CV risk in T2D patients treated with OAD.

Effects of yoga on cardiometabolic risks and fetomaternal outcomes are associated with serum nitric oxide in gestational hypertension: a randomized control trial.

Gestational hypertension (GH) is associated with adverse cardiometabolic and pregnancy outcomes. Though yoga is known to be beneficial in pregnancy, the effects of yoga rendered for twenty weeks starting from 16th week of gestation in pregnant women having risk of GH on the incidence of hypertension, cardiometabolic risks and fetomaternal outcomes have not been studied. A randomized control trial was conducted on 234 pregnant women having risk of GH receiving standard antenatal care (Control group, n = 113), and receiving standard care + yoga (Study group, n = 121). Interventions were given for twenty weeks starting at 16th week of gestation. Baroreflex sensitivity (BRS), heart rate variability (HRV), insulin resistance, lipid-risk factors, and markers of inflammation, oxidative stress and vascular endothelial dysfunction (VED) were assessed before and after intervention. Incidence of new-onset hypertension, level of cardiometabolic risks at 36th week, and fetomaternal-neonatal outcomes in the perinatal period, were noted. The link of hypertension, pregnancy outcomes and cardiometabolic risks with nitric oxide (NO), the marker of VED was assessed by analysis of covariance, Pearson's correlations, and multilinear and logistic regressions. In study group, 6.61% women developed hypertension compared to 38.1% in the control group following 20-week intervention and there was significant decrease in risk of developing GH (RR, 2.65; CI 1.42-4.95). There was less-painful delivery, decreased duration of labor, increased neonatal birthweight and Apgar score in study group. Increase in total power of HRV (ß = 0.187, p = 0.024), BRS (ß = 0.305, p < 0.001), and decrease in interleukin-6 (ß = - 0.194, p = 0.022) had significant association with increased NO. Twenty weeks of practice of yoga during pregnancy decreases the incidence of hypertension, improves fetomaternal outcomes, and reduces cardiometabolic risks in pregnant women having risk of GH. Decreased blood pressure, increased HRV, BRS and birth weight and decreased inflammation were associated with improved endothelial function.

Cardiovagal modulation and oxidative stress in hypothyroidism on maintenance therapy.

AIM: To analyze the autonomic control of heart rate variability (HRV) in subjects with peripheral hypothroidism undergoing hormone replacement therapy with L-thyroxine (L-T4) for 5-10 years. METHODS: Thyroid profile, lipid profile, lipid-risk factors, parameters of oxidative stress [malondialdehyde (MDA)], inflammation [high-sensitive C-reactive protein (CRP)] and Heart rate variability (HRV) was analyzed in thirty-eight hypothyroid patients on treatment for more than five years and compared with healthy euthyroid volunteers of similar age, gender, and body composition. The link of oxidative stress with HRV parameters was assessed by Spearman-Rho correlation and regression analyses. RESULTS: Hypothyroid patients on L-T4 treatment, had higher TSH (p<0.01), lipid profile (p<0.05) and lipid risk factors (p<0.05), high-sensitive C-reactive-protein (hsCRP) (3.31 versus 4.95 mg/L; p<0.05) and MDA (2.66 versus 6.87 µm/L; p <0.001) in serum. There was gross reduction in HRV parameters [reduced standard deviation of NN interval (SDNN), root mean square of successive differences between normal heartbeats (RMSSD), total power (TP) and elevated ratio of low to high frequency power (LF/HF ratio)] in patients. Elevated MDA was correlated with vagal withdrawal (decreased SDNN, RMSSD and TP) and TSH. In multiple regression analysis TSH and TP contributed to the rise in MDA. CONCLUSION: Hormone replacement therapy with L-T4 for hypothyroidism alone does not resolve persistent hyperlipidemia, oxidative stress and inflammation in primary hypothyroid patients even after five years of treatment. Association of oxidative stress with reduced cardiovagal modulation in these patients suggests persistence of cardiovascular risk despite standard treatment which warrants further investigation.

Comparison of albumin adjusted ischemia-modified albumin and total antioxidant status in patients with locally advanced head and neck cancer: A pilot study.

Background: Among all types of cancers in India, head and neck cancer (HNC) accounts for 30%. Oxidative stress (OS) is one of the aetiologies for cancer. However, it is not evaluated for these patients scheduled for anticancer therapy. Therefore, in the present study, we have compared two biochemical markers in HNC patients before therapy to assess their suitability as a marker for ongoing OS in the locally advanced stage of HNC. Materials and Methods: We measured the body mass index (BMI), waist-hip ratio (WHR), blood pressure (BP), albumin, total antioxidant status (TAS), ischemia modified albumin (IMA), and albumin adjusted IMA (AdjIMA) in forty locally advanced squamous cell carcinoma HNC patients and compared with forty healthy individuals of similar age and gender. AdjIMA and TAS were compared by the receiver operating curve. Results: BMI and WHR were significantly lower in HNC patients with no difference in BP parameters. Both IMA and AdjIMA were higher and TAS was lower in HNC patients. TAS was positively associated with BMI and negatively with AdjIMA. Between AdjIMA and TAS, AdjIMA at an optimal cutoff value of 0.23 absorbance unit had higher sensitivity (71%), specificity (65%), and area under the curve (0.710 vs. 0.365). Conclusion: Antioxidant levels are grossly altered in HNC patients. AdjIMA can be considered a better marker for assessing OS in HNC patients than TAS.

Comparison of Two Stump Closure Techniques in Laparoscopic Appendicectomy: A Single-Centre Prospective Cohort Study.

Introduction Acute appendicitis is a frequent illness that manifests as an emergency and most of the cases necessitate surgical intervention. One of the most critical processes in a laparoscopic appendicectomy is the closure of the appendicular stump. For the closure of the stump of the appendix, several approaches have been employed and explored, but the one with the best outcomes has yet to be proved. The purpose of this study was to evaluate the medical results and cost analyses of laparoscopic appendicectomy with two of the commonly used stump closure techniques - ENDOLOOP® and Hem-o-lok®. Materials and methods A two-year prospective hospital-based cohort study was conducted from June 2019 to July 2021. All the patients in the study were randomly assigned to one of two experimental arms (ENDOLOOP® and Hem-o-lok®). The clinical and follow-up data of these patients were collected and tabulated into a data sheet and analyzed. Results In total, 180 individuals were included in the research (90 in each arm). No statistically significant difference was found in comparing the age, gender or diameter of the appendix among the two groups. The time taken for surgery showed significant differences among the two study groups. The time taken for the procedure in the Hem-o-lok® group was significantly lower than the ENDOLOOP® group (40.3 ± 12.3 minutes vs 50.83 ± 10.5 minutes, p < 0.001). No intraoperative or immediate postoperative complications were noted in either of the groups. The average duration of hospital stay was 2.7 ± 0.9 days in the Hem-o-lok® group, while it was 3.1 ± 0.8 days in the ENDOLOOP® group (p = 0.986). The material cost for the stump ligation with Hem-o-lok® was Rs. 310 ± Rs. 76 while that using ENDOLOOP® was Rs. 630 ± Rs. 118 (p < 0.001). In the Hem-o-lok® subset of patients, the mean direct expenses of laparoscopic appendicectomy were considerably lower. During the 12-week follow-up period, none of the patients had any post-operative complications. Conclusion According to the results of this study, both the technical variations of appendix stump closure are equal in terms of postoperative complications. When compared to the ENDOLOOP® group, the Hem-o-lok® group had a shorter duration of surgery and ended up spending less money. Hem-o-lok® clips have the potential to become the preferred way of anchoring the appendix base during laparoscopic appendicectomy.

Link of neurocognitive deficit to impaired cardiovagal modulation in prehypertensives is comparable to newly diagnosed hypertensives in young Indian population.

BACKGROUND: Hypertension has been reported to cause impaired cardiovagal modulation and a wide variety of cognitive loss. However, the link cardiovagal modulation to neurocognitive impairment has not been studied yet. The present study has compared the link cardiovagal modulation to neurocognitive impairment between prehypertension and newly diagnosed hypertension in young adults. METHODS: One hundred forty-seven subjects (42 normotensives, 54 prehypertensives and 51 newly diagnosed hypertensives) aged between 18-44 years were included in this case-control study. The demographic, anthropometric, basal parameters, heart rate variability (HRV), cardiovascular autonomic function tests (CAFTs), event-related potential P300 and biochemical parameters were recorded in all the groups. Association of various parameters with neurocognitive deficit was studied by Pearson correlation analysis and independent contribution of various factors to cognitive deficit was assessed by multiple regression analysis in the study groups. RESULTS: Total power (TP) of HRV, the marker of cardiovagal modulation was reduced in both prehypertensives and hypertensives compared to controls. Among CAFTs, the ΔDBPIHG was increased, and 30:15 ratio and E:I ratio were decreased in both study groups. The latency of P300 (the marker of neurocognition) was significantly prolonged in prehypertensives and hypertensives and P300 latency was significantly associated with reduction in TP in both the groups. HOMA-IR was increased, and total oxidant capacity was decreased in prehypertensives and hypertensives, and both these parameters had independent contribution to P300. CONCLUSION: Prehypertensives had considerable autonomic imbalance, reduced cardiovagal modulation and neurocognitive deficit that were comparable to newly diagnosed hypertensives. Though the causal relationship between cardiovagal modulation and neurocognitive impairment can't be established from the findings of the present study, it appears that neurocognitive deficit might have some possible link to the decreased cardiovagal modulation and metabolic derangements in young prehypertensives and hypertensives.

Effects of 12 Weeks Practice of Yoga on Heart Rate Variability in Males with Type 2 Diabetes Receiving Oral Antidiabetic Drugs: A Randomized Control Trial.

Objective: To investigate the effects of 12 weeks practice of a structured yoga module on heart rate variability (HRV) and cardiometabolic risks in patients with type 2 diabetes (T2D) receiving similar kind of oral antidiabetic drugs (OAD) with yoga therapy and without yoga therapy, matched for all the known confounders. Design: Parallel design interventional (randomized control trial) study. Subjects: Eighty treatment-naive males with T2D were randomized into control group (n = 40) and study group (n = 40). Intervention: Study group participants received a structured yoga therapy that included asana and pranayama practice for 12 weeks in addition to OAD, whereas control group participants received OAD alone. Outcome measures: Before and after intervention, BP parameters, rate pressure product (RPP) as the marker of myocardial stress, total power (TP) of HRV, low-frequency to high-frequency (LF-HF) ratio of HRV, homeostatic model of insulin resistance (HOMA-IR), lipid profile and lipid risk factors, malondialdehyde (MDA), and high-sensitive C-reactive protein (hsCRP) were measured. TP of HRV was defined as the primary outcome. Association of TP (the marker of HRV) and LF-HF ratio (the marker of sympathovagal balance) with cardiometabolic parameters was assessed by correlation and regression analyses. Results: After 12 weeks yoga therapy, there was significant reduction in cardiometabolic risks (TP of HRV, RPP, lipid risks factors, levels of MDA, and hsCRP) in study group subjects compared with control subjects that did not receive yoga therapy. All cardiometabolic risk factors were significantly correlated with TP in study group, having maximum significance with homeostatic model of insulin secretion (r = 0.502, p ≤ 0.001). Multiple regression analysis demonstrated the independent contribution of decrease in RPP, HOMA-IR, hsCRP, and MDA to increased TP and decreased LF-HF ratio in T2D patients after yoga therapy. Conclusion: From the results of this study, the authors conclude that 12 weeks practice of a structured yoga module improves TP of HRV, sympathovagal balance, and metabolic functions, and reduce cardiovascular (CV) risks in patients with diabetes who received routine antidiabetic medicines along with yoga therapy, compared with the patients with diabetes who received antidiabetic medicines alone. The reduction in cardiometabolic risks in these patients is linked to the improvement in TP of HRV. Future studies should also include a control group with rapid walking or a similar exercise program of equal time to the yoga intervention group to discern whether it is in fact yoga that is leading to these results and not simply increased CV activity.

Association of osteoprotegerin gene T950C polymorphism with cardiometabolic risk factors in gestational diabetes mellitus in South Indian Tamilian women.

BACKGROUND & AIMS: This study was designed to explore the relevance of Osteoprotegerin (OPG) and its polymorphism in the cardiometabolic risk in gestational diabetes mellitus patients before diet-therapy (GDMA1). METHODS: South Indian Tamilian pregnant women were screened and 145 were grouped as GDMA1 (n = 73) and normal pregnancy (n = 72). Serum OPG, TNF α, lipid profile, insulin and blood pressure was compared. Genomic DNA was analysed for rs2073617 T950C polymorphism. Chi square test was done to analyze the frequency distribution of alleles. Multiple regression analysis was done to assess the association among cardiometabolic parameters. RESULTS: TNF α (p < 0.01), Osteoprotegerin (p < 0.01), lipid profile (p < 0.01), atherogenic indices (p < 0.01), systolic and diastolic and blood pressure (<0.001) levels were higher in GDMA1 patients. TNF α (p < 0.01) and osteoprotegerin (p < 0.01) were higher in women with CT allele. Osteoprotegerin was independently contributed by BMI in all GDMA1 cases and diastolic blood pressure (DBP) in CT allele cases. There was significantly higher odd (OR = 3.63) in the distribution of CT genotype among the multiparous women. CONCLUSIONS: Osteoprotegerin, atherogenic lipid risk factor and inflammation are higher in GDMA1 women. Rise in OPG is contributed by high BMI in GDMA1 women. Higher odds of CT allele distribution in multiparous women suggests that TT allele women are at higher risk of developing GDM in their first pregnancy. Further analysis of T950C polymorphism in a larger cohort is warranted to confirm its role.
