Intravoxel incoherent motion and diffusion kurtosis imaging and their machine-learning-based texture analysis for detection and assessment of prostate cancer severity at 3 T.

OBJECTIVES: To evaluate the role of combined intravoxel incoherent motion and diffusion kurtosis imaging (IVIM-DKI) and their machine-learning-based texture analysis for the detection and assessment of severity in prostate cancer (PCa). MATERIALS AND METHODS: Eighty-eight patients underwent MRI on a 3 T scanner after giving informed consent. IVIM-DKI data were acquired using 13 b values (0-2000 s/mm2) and analyzed using the IVIM-DKI model with the total variation (TV) method. PCa patients were categorized into two groups: clinically insignificant prostate cancer (CISPCa) (Gleason grade ≤ 6) and clinically significant prostate cancer (CSPCa) (Gleason grade ≥ 7). One-way analysis-of-variance, t test, and receiver operating characteristic analysis was performed to measure the discriminative ability to detect PCa using IVIM-DKI parameters. A chi-square test was used to select important texture features of apparent diffusion coefficient (ADC) and IVIM-DKI parameters. These selected texture features were used in an artificial neural network for PCa detection. RESULTS: ADC and diffusion coefficient (D) were significantly lower (p < 0.001), and kurtosis (k) was significantly higher (p < 0.001), in PCa as compared with benign prostatic hyperplasia (BPH) and normal peripheral zone (PZ). ADC, D, and k showed high areas under the curves (AUCs) of 0.92, 0.89, and 0.88, respectively, in PCa detection. ADC and D were significantly lower (p < 0.05) as compared with CISPCa versus CSPCa. D for detecting CSPCa was high, with an AUC of 0.63. A negative correlation of ADC and D with GS (ADC, ρ = -0.33; D, ρ = -0.35, p < 0.05) and a positive correlation of k with GS (ρ = 0.22, p < 0.05) were observed. Combined IVIM-DKI texture showed high AUC of 0.83 for classification of PCa, BPH, and normal PZ. CONCLUSION: D, f, and k computed using the IVIM-DKI model with the TV method were able to differentiate PCa from BPH and normal PZ. Texture features of combined IVIM-DKI parameters showed high accuracy and AUC in PCa detection.

The so-called "one-and-a-half" ventricular repair: where are we after 40 years?

OBJECTIVES: The indications, timing, and results of the so-called "one-and-a-half ventricle repair", as a surgical alternative to the creation of the Fontan circulation, or high-risk biventricular repair, currently remain nebulous. We aimed to clarify these issues. METHODS: We reviewed a total of 201 investigations, assessing selection of candidates, the need for atrial septal fenestration, the fate of an unligated azygos vein and free pulmonary regurgitation, the concerns regarding reverse pulsatile flow in the superior caval vein, the growth potential and function of the subpulmonary ventricle, and the role of the superior cavopulmonary connections as an interstage procedure prior to biventricular repair, or as a salvage procedure. We also assessed subsequent eligibility for conversion to biventricular repair and long-term functional results. RESULTS: Reported operative mortalities ranged from 3% to 20%, depending on the era of surgical repair with 7% risk of complications due to a pulsatile superior caval vein, up to one-third incidence of supraventricular arrhythmias, and a small risk of anastomotic takedown of the superior cavopulmonary connection. Actuarial survival was between 80% and 90% at 10 years, with two-thirds of patients in good shape after 20 years. We found no reported instances of plastic bronchitis, protein-losing enteropathy, or hepatic cirrhosis. CONCLUSIONS: The so-called "one-and-a-half ventricular repair", which is better described as production of one-and-a-half circulations can be performed as a definitive palliative procedure with an acceptable risk similar to that of conversion to the Fontan circulation. The operation reduces the surgical risk for biventricular repair and reverses the Fontan paradox.

Serum sestrins: potential predictive molecule in human sarcopenia.

BACKGROUND: The aging trajectory from a state of robustness and good health proceeds from sarcopenia to frailty followed by disability and death due to decline in skeletal muscle mass and function. Sarcopenia is now formally recognized as a muscle disease with an ICD-10-MC diagnosis code. The autophagic response seems to be affected in the skeletal muscle during aging contributing to sarcopenia. Sestrins (Sesns) proteins play a critical role in autophagy induction under cellular stress conditions. AIMS: The study aims to identify sarcopenia in older adults using Asian Working group guidelines (AWGS) to determine clinically relevant cut-off levels for diagnosis and their association with antioxidant protein Sesns. METHODS: The study recruited 102 older adults attending Geriatric medicine OPD AIIMS, New Delhi, India. The level of serum Sesns were evaluated by Surface Plasmon Resonance (SPR) and validated by immunoblotting. Fifty older adults were diagnosed as sarcopenics according to AWGS. RESULTS: Sesn 1 (p = 0.0448) and Sesn 2 (p < 0.0001) levels were significantly reduced in sarcopenic compared to non-sarcopenic. ROC analysis showed a better cut-off of Sesn 2; 10.104 ng/µL with 92% sensitivity and 84% specificity. Even after adjusting the values with respect to confounding factors, Sesn levels remained significantly reduced in sarcopenics (p < 0.030). DISCUSSION: The level of Sesn 2 showed positive co-relation with the characteristics of sarcopenia. This study first time reported the concentration of serum sestrin in sarcopenic older adults. CONCLUSION: It can be concluded that sarcopenia can be diagnosed at the early stage by using the serum sestrin scale as one of the potential biomarker.

Effect of deep tissue laser therapy treatment on peripheral neuropathic pain in older adults with type 2 diabetes: a pilot randomized clinical trial.

BACKGROUND: This study assessed the safety and efficacy of deep tissue laser therapy on the management of pain, functionality, systemic inflammation, and overall quality of life of older adults with painful diabetic peripheral neuropathy. METHODS: The effects of deep tissue laser therapy (DTLT) were assessed in a randomized, double-masked, sham-controlled, interventional trial. Forty participants were randomized (1:1) to receive either DTLT or sham laser therapy (SLT). In addition to the standard-of-care treatment, participants received either DTLT or SLT twice weekly for 4 weeks and then once weekly for 8 weeks (a 12-week intervention period). The two treatments were identical, except that laser emission was disabled during SLT. Assessments for pain, functionality, serum levels of inflammatory biomarkers, and quality of life (QOL) were performed at baseline and after the 12-week intervention period. The results from the two treatments were compared using ANOVA in a pre-test-post-test design. RESULTS: All participants randomized to the DTLT group and 85% (17 of 20) of participants randomized to the SLT group completed the trial. No significant differences in baseline characteristics between the groups were observed. After the 12-week intervention period, pain levels significantly decreased in both groups and were significantly lower in the DTLT group than in the SLT group. The Timed Up and Go test times (assessing functionality) were significantly improved in both groups and were 16% shorter in the DTLT group than in the SLT group. Serum levels of IL-6 decreased significantly in both groups. Additionally, serum levels of MCP-1 decreased significantly in the DTLT group but not in the SLT group. Patients' quality of life improved significantly in the DTLT group but not in the SLT group. CONCLUSIONS: Deep tissue laser therapy significantly reduced pain and improved the quality of life of older patients with painful diabetic peripheral neuropathy. TRIAL REGISTRATION: Clinical Trial Registry-India CTRI/2017/06/008739 . [Registered on: 02/06/2017]. The trial was registered retrospectively.

Can Echocardiographic Right Ventricular Function Parameters Predict Vasoactive Support Requirement After Tetralogy of Fallot Repair?

OBJECTIVE: To evaluate the role of echocardiographic right ventricular function parameters in predicting postoperative vasoactive inotrope requirement after tetralogy of Fallot repair. DESIGN: Prospective observational study. SETTING: A tertiary care hospital. PARTICIPANTS: Fifty-two children undergoing elective intracardiac repair. INTERVENTIONS: Comprehensive transesophageal echocardiography was performed before and after surgery. Fractional shortening, fractional area change, tricuspid annular plane systolic excursion (TAPSE), right ventricular myocardial performance index, tricuspid annular velocities (S', E', A'), and right ventricular global longitudinal strain and strain rate (RV Gls and RV Glsr) were measured. The ratio of peak systolic pressure of the right and left ventricles (Prv/lv) was measured directly from the surgical field pre- and post-repair. The inotrope requirement during first 24 postoperative hours was calculated using the mean Vasoactive-Inotropic Score (VIS). Pearson correlation analysis was used to study the relation between echocardiographic parameters and VIS as well as Prv/lv and VIS. Receiver operating characteristic analysis was used to study the predictive strength of parameters. MEASUREMENTS AND MAIN RESULTS: Among the measured parameters, both pre- and post-repair TAPSE had significant negative correlation with the mean VIS (p < 0.05). Both pre- and post-repair right ventricular myocardial performance index and S', E', A', RV Gls, RV Glsr, Prv/lv also had significant correlation with the mean VIS (p < 0.05). Of these, TAPSE, RV Gls, RV Glsr, and Prv/lv had significant predictive strength (p < 0.05) and reasonable sensitivity and specificity (area under the curve > 0.6) for predicting high mean VIS (VIS > 20). CONCLUSION: Tricuspid annular plane systolic excursion, RV Gls, RV Glsr, and Prv/lv could predict a postoperative high mean VIS with significant strength and reasonable sensitivity and specificity.

Comparative Validation of Abdominal CT Models that Predict Need for Surgery in Adhesion-Related Small-Bowel Obstruction.

INTRODUCTION: Adhesion-related small-bowel obstruction (ASBO) can be managed without surgery in selected patients. The aim of this study was to validate three previously published computed tomography (CT) models that predict need for surgery. METHODS: A retrospective study of patients with ASBO admitted to a tertiary referral hospital between November 2009 and April 2015 was conducted. Data on clinical variables were extracted from medical records. CT signs were assessed by a radiologist who was blinded to whether or not the patients required surgery. Three previously published models were validated by testing their ability to predict need for surgery. RESULTS: The cohort comprised 233 patients with ASBO (mean age 69.7 years, 47.6% male), of whom 73 (31.3%) required surgery. A predictive model using a combination of mesenteric oedema, free intraperitoneal fluid and absence of small-bowel faecalisation had a sensitivity of 38% [95% CI 27-50%], specificity of 88% [81-92%], positive likelihood ratio (LR+) of 3.1 [1.6-5.1] and negative likelihood ratio (LR-) of 0.7 [0.6-0.8]. Only the results of one previously published model (which used a combination of obstipation, free intraperitoneal fluid and high-grade or complete obstruction) could be reproduced. This model had a potentially clinically useful LR+ of 2.9 [1.1-7.4] and LR- of 0.9 [0.8-1.0]. The poor performances of the other two models may be partially explained by measurement bias. CONCLUSION: The performances of the previously published predictive models in this validation study were varied. Future attempts to develop models should use clearly defined, standardised and reproducible predictors wherever possible.

Repetitive Transcranial Magnetic Stimulation of the Dorsolateral Prefrontal Cortex for Phantom Limb Pain.

BACKGROUND: Phantom limb pain (PLP) is a prevalent and distressing occurrence in 60-80% of individuals who have undergone amputations. Recent research underscores the significance of maladaptive cortical plasticity in the genesis of PLP, emphasizing the importance of targeting cortical areas for therapeutic interventions. Repetitive transcranial magnetic stimulation (rTMS), a noninvasive tool for cortical stimulation, demonstrates effectiveness in treating various chronic pain conditions of neuropathic origin. Nevertheless, there exists a limited body of research investigating the application of rTMS as a therapeutic intervention specifically for managing PLP. Notably, the dorsolateral prefrontal cortex (DLPFC) plays a crucial role in central pain processing, suggesting its potential as a key therapeutic target in PLP treatment. There is a lack of adequate data regarding the effectiveness of DLPFC-targeting rTMS in alleviating the pain experienced by PLP patients. OBJECTIVE: In this study, our aim was to investigate the impact of 10 sessions of DLPFC-targeting rTMS on the pain status of individuals experiencing PLP. STUDY DESIGN: Randomized controlled trial. SETTING: Traumatic amputees reporting to the tertiary care center with PLP. METHODS: The study was approved by the Institute Ethics Committee (IECPG-299/27.04.2022) and registered in the Clinical Trials Registry of India (CTRI/2022/07/043938). Nineteen patients suffering from PLP were recruited and randomized into real or sham rTMS groups. In the real rTMS group, patients received 10 sessions of rTMS at the DLPFC contralateral to the amputation site. The rTMS, administered at 90% of the resting motor threshold (RMT), was delivered as 8 trains of 150 pulses per train at the rate of one Hz and an inter-train interval of 60 seconds. The total number of pulses per session was 1,200. The sham group received 10 sessions of sham rTMS through the perpendicular placement of an rTMS coil over the DLPFC. These sessions lasted for the same duration and included the same sounds as the real group but involved no active stimulation. The patients' pain status was evaluated using the Visual Analog Scale (VAS) at baseline, at the end of each session of real or sham rTMS and at the 15th, 30th, and 60th day after the the completion of real or sham therapy. RESULTS: A significant decrease in VAS scores was noted after 10 sessions of real rTMS that targeted the DLPFC, in contrast to the sham rTMS group. The real rTMS group's reduction in VAS scores also persisted during the follow-up. LIMITATIONS: A few patients had to drop out due to physical restrictions and financial constraints. Consequently, only a small number of individuals were able to complete the study protocol successfully. CONCLUSION: A regimen of 10 sessions of real rTMS of the DLPFC was associated with significant pain relief in patients with PLP, and the effects were sustained for 2 months. Therefore, the present study shows that rTMS of the DLPFC has potential as an effective therapeutic intervention for sustained pain relief in PLP patients.

A Systematic Review of the Statistical Methods Adopted for Analyzing Follow-Up Data in Cohort Multiple Randomized Controlled Trial.

BACKGROUND: The cohort multiple randomized controlled trial (cmRCT) can tackle some of the weaknesses of an RCT which has triggered the interest of researchers considerably over time. Several challenges persist regarding the methods of analyzing such valued data. The paucity of international recommendations concerning the statistical methods for analyzing trial data has led to a variety of strategies further complicating the result comparison. Our aim was to review the different cmRCT analysis methods since cmRCT was first proposed in 2010. METHODOLOGY: A search for full-length studies presenting statistical analysis of the data collected adopting a cmRCT design was conducted on PubMed, Cochrane Library, EMBASE, JSTOR, Scopus, MEDLINE, and ClinicalTrials.gov. RESULTS: Out of 186 studies screened, we selected 22 for the full-text screening and 11 were found eligible for data extraction. All 11 studies were conducted in high-income countries, reflecting the design being underutilized in other settings. All of the studies were found to have used intention-to-treat (ITT) analysis with four of them utilizing instrumental variables (IV) analysis or a complier average causal effect (CACE). Randomization was noted often to be interchangeably used for random selection. Sample size calculation was not clearly specified in the majority of the studies. CONCLUSION: Clarity regarding the distinction between an RCT and a cmRCT is warranted. The fundamental difference in design, which leads to certain biases that need to be taken care of by adopting IV or CACE analysis, has to be understood before taking up a cmRCT.

Re-188 lipiodol in hepatocellular carcinoma with portal vein thrombosis: a pilot study using novel chelating agent N-DEDC and its comparison with (A)HDD.

OBJECTIVE: Hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) have limited therapeutic options, Re-188 lipiodol transarterial therapy being one of them. We aimed to assess the safety and efficacy of Re-188 lipiodol exclusively in HCC with PVT as well as to compare two chelating agents for the synthesis of Re-188 lipiodol: novel bis-(diethyldithiocarbamato) nitrido (N-DEDC) with existing acetylated 4-hexadecyl 1-2,9,9-tetramethyl-4,7-diaza-1,10-decanethiol [(A)HDD]. METHODS: Patients with radiological diagnosis of HCC with PVT having Eastern Cooperative Oncology Group (ECOG) performance status ≤2 and Child Pugh score (PS) A or B were recruited. Patients received an empirical dose of transarterial Re-188 lipiodol, labelled with (A)HDD or N-DEDC. Radiological response on MRI (modified response evaluation criteria in solid tumors), biochemical response with serum alpha fetoprotein and clinical response with ECOG PS was assessed at three months and survival was estimated at the end of the study. RESULTS: Fifteen therapies were performed in 14 patients with a median age of 62 years (range: 41-70 years). Eight therapies were with Re-188 (A)HDD lipiodol and seven with Re-188 N-DEDC lipiodol. Overall mean injected dose was 2.6 ±â€…0.37 GBq. Radiological objective response rate was 31% and disease control rate was 85%. Mean overall survival was 14.21 months and mean progression free survival was 10.23 months. Percentage survival assessed at 3, 6 and 9 months was 93%, 64% and 57%, respectively. Safety parameters, response and survival outcome were comparable for (A)HDD and N-DEDC groups. CONCLUSION: Transarterial Re-188 lipiodol in HCC with PVT is safe and effective in disease control as well as improving survival outcome. Additionally, cost-effective and high-yielding novel agent N-DEDC appears to be a comparable alternative to (A)HDD for the same.

A comprehensive evaluation of predictors of obesity in women during the perimenopausal period: A systematic review and narrative synthesis.

INTRODUCTION: Obesity during perimenopausal transition can be attributed to various factors. Identifying these factors is crucial in preventing obesity and developing effective strategies to manage weight during this phase. This review aimed to systematically understand predictors of obesity during menopausal transition. METHODS: The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched databases like PubMed, Wiley Online Library, and Cochrane Reviews. Cohort and cross-sectional studies in English language assessing obesity among menopausal women were included. The methodological quality was assessed using Joanna Briggs Checklist for critical appraisal. Risk of Bias (RoB) was generated using Review Manager 5.4.1 (RevMan). Identified predictors were assessed for overall quality of evidence using adopted Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: This review encompassed 42 studies, (21 cross-sectional and 21 cohort) with sample ranging from 164 to 107,243 across studies. Higher parity( ≥ 3 children) emerged as a strong predictor of obesity across seven studies, with good-quality evidence. Lower physical activity was another predictor, supported by eight studies with good-quality evidence. Sociodemographic factors like lower education(<8 years or < than college degree), socioeconomic background, menopausal transition, and older age at menarche showed associations with weight gain, with moderate-quality evidence. Lifestyle factors (high-fat consumption, sedentariness, active smoking status, and psychological difficulties) also showed moderate-quality evidence. CONCLUSION: This review underscores the multifaceted factors associated with obesity during the perimenopausal transition. Identifying these factors will be helpful in prevention and management of obesity among these women.

The Surgical Significance of Phenotypic Variability in the Setting of Tetralogy of Fallot.

The phenotypic feature of tetralogy of Fallot is anterocephalad deviation of the muscular outlet septum, or its fibrous remnant, relative to the septoparietal trabeculation, coupled with hypertrophy of septoparietal trabeculations. Although this feature permits recognition of the entity, no two cases are identical. Once diagnosed, treatment is surgical. The results of surgical treatment have improved remarkably over recent decades. The results are now sufficiently excellent, including those in the developing world, that attention is now directed toward avoidance of morbidity, while still seeking, of course to minimize any fatalities due to surgical intervention. It is perhaps surprising that attention thus far has not been directed on the potential significance of phenotypic variation relative to either mortality or morbidity subsequent to surgical correction. The only study we have found specifically addressing this variability focused on the extent of aortic override, and associated malformations, but made no mention of variability in the right ventricular margins of the interventricular communication, nor the substrates for subpulmonary obstruction. In this review, therefore, we assessed the potential significance of known morphological variability to the outcomes of surgical intervention in over 1,000 individuals undergoing correction by the same surgeon in a center of excellence in a developing country. We sought to assess whether the variations were associated with an increased risk of postoperative death, or problems of rhythm. In our hands, double outlet ventriculoarterial connection was associated with increased risk of death, while the presence of a juxta-arterial defect with perimembranous extension was associated with rhythm problems.

Pre-vascular Facial Nodes: Sentinel Station for Metastasis in Gingivobuccal Complex Cancers.

BACKGROUND: Pre-vascular facial nodes (PV-FNs; perifacial lymph nodes) are supra-mandibular lymph nodes above the inferior border of the mandible. These are not part of routine neck dissection done for OCSCC. These lymph nodes can be sentinel station for metastatic lymph nodes from gingivobuccal complex cancers and are missed during routine neck dissection. It is imperative to include this sentinel station in routine neck dissection to prevent nodal recurrences. MATERIALS AND METHODS: One hundred thirty-seven patients with GBCC (T1-T4) were prospectively recruited between May 2020 and June 2022 with the intent to evaluate the incidence of PV-FN metastases and clinicopathological factors predicting them. RESULTS: PV-FN metastases were seen in 26 patients (18.9%; 26/137). The occult metastasis rate was 8.7% (12/137). On multivariate analysis, pathological T4 stage (pT4), LVE positivity, and intermediate-high BGS were statistically significant predictors of PV-FN metastases in our study. CONCLUSIONS: Incidence of PV-FN metastasis is high (18.9%) in GBCC, which can be potentially the first sentinel station in the lymphatic drainage pattern for this sub-site. Meticulous clearance of this nodal basin is of paramount importance during neck dissection to prevent nodal recurrences. LEVEL OF EVIDENCE: Level 2 (CEBM-Level of Evidence-2.1) Laryngoscope, 2024.

Impact of Structured Reporting of Skeletal Survey in Skeletal Dysplasia: A Single Institution Experience.

Background Structured reporting has the advantages of reducing ambiguity in written radiology reports with greater uniformity and comparability of reports amongst different institutes. It has multiple facets: structured format, structured content, and standardized language. While structured reporting initiative has been used in various radiology subspecialties such as oncology, cardiothoracic, abdominal and interventional radiology; skeletal dysplasia is a domain that remains largely untouched by this concept. Purpose To evaluate the impact of structured reporting in skeletal dysplasia. Methods and Materials This was an ethically approved pragmatic clinical trial. A defined number (75) of clinically diagnosed and/or genetically confirmed skeletal dysplasia radiographs were evaluated by two radiologists (reader A and reader B) with 5-and 7-years' experience in general radiology, respectively. A pre-defined structured reporting format for skeletal dysplasia was used as an interventional tool. Both the readers interpreted the radiographs before and after the training session. In addition to diagnosis, diagnostic confidence was noted using a semiquantitative scale. Improvement in diagnostic accuracy and diagnostic confidence after training were assessed. McNemar's test was used to assess the statistical significance of difference in proportion of correct diagnoses in pre- and post-education phases. An interrater reliability analysis using the Kappa statistic was performed to determine interobserver agreement between readers both in pre- and post-education phases. Results In the post-education phase, the proportion of accurate diagnosis improved from 48% (36/75) to 64% (48/75) for reader A, and from 44% (33/75) to 60% (45/75) for reader B as compared with the pre-education phase. Amongst the cases with a correct radiologic diagnosis, an increase in diagnostic confidence was noted in 18 cases for reader A, and 15 cases for reader B. In none of the cases, there was a reduction in diagnostic confidence after training. A McNemar's test determined that there was a statistically significant difference in the proportion of correct diagnoses in pre- and post-education phases, p < 0.001. The interobserver agreement between the readers was found to increase from Kappa = 0.33 ( p = 0.004) using non-structured reporting in pre-education phase to Kappa = 0.46 ( p < 0.001) using structured reporting in the post-education phase. Conclusion A structured reporting of skeletal survey can improve accuracy and confidence in diagnosing skeletal dysplasia.

Prevalence of sarcopenia and its determinants in people with type 2 diabetes: Experience from a tertiary care hospital in north India.

OBJECTIVES: Changes in skeletal muscle mass and quality are associated with type 2 Diabetes (T2D) and its complications. We evaluated the prevalence of sarcopenia in patients with T2D and its association with various anthropometric and metabolic parameters. METHODS: A total of 229 patients with T2D, ≥20-60 years, were screened for sarcopenia using handgrip strength (HGS) by dynamometer, physical performance test (by Short Physical and chair stand test), and height-adjusted appendicular skeletal muscle index (ASMI) by Dual Energy X-ray Absorptiometry (DXA) applying Asian Working Group on Sarcopenia (AWGS). Multiple logistic regressions were performed to identify the factors associated with sarcopenia. RESULTS: The mean age was 46.2 ± 7.4 years with 55% being women. The prevalence of low HGS, poor physical performance, low ASMI, possible sarcopenia, sarcopenia, and severe sarcopenia was 16.2%, 39.3%, 33%, 43%, 18.8%, and 6.1%, respectively. Age >45 years and use of >2 oral hypoglycaemic agents (OHA's) were risk factors for low HGS (OR:3.51, 95%CI = 1.5-8.3) and low ASMI (OR:2.40, 95%CI = 1.05, 5.49, p-0.04), respectively. Female sex (OR:3.3 1.8-6.1 p < 0.01), age >45 years (OR:2.12, 95% CI = 1.2-3.8 p-0.012) and liver fibrosis (OR: 2.12, 95% CI = 1.01-4.46 p-0.048) were independently associated with poor performance. No association was found with HbA1c, dyslipidaemia, albuminuria, hypertension, or duration of diabetes and sarcopenia. CONCLUSION: Sarcopenia is becoming increasingly recognized as a significant complication in younger individuals with T2D, and poor physical performance plays a vital role in its development. The prevalence of sarcopenia rises with advancing age, underscoring the importance of early intervention to address this condition.

Long-Term Surgical Outcomes of Patients With Isomeric Right and Left Atrial Appendages.

Objectives: To compare the long-term outcomes of biventricular, univentricular, and so-called one-and-one-half ventricular repairs in patients with left and right isomerism. Methods: Surgical correction was undertaken, between 2000 and 2021, in 198 patients with right, and 233 with left isomerism. Results: The median age at operation was 24 days (interquartile range [IQR]: 18-45) and 60 days (IQR: 29-360) for those with right and left isomerism, respectively. Multidetector computed-tomographic angiocardiography demonstrated more than half of those with right isomerism had superior caval venous abnormalities, and one-third had a functionally univentricular heart. Almost four-fifths of those with left isomerism had an interrupted inferior caval vein, and one-third had complete atrioventricular septal defect. Biventricular repair was achieved in two-thirds of those with left isomerism, but under one-quarter with right isomerism (P < .001). Hazard regression for mortality revealed odds for prematurity at 5.5, pulmonary atresia at 2.81, atrioventricular septal defect with a common valvar orifice at 2.28, parachute mitral valve at 3.73, interrupted inferior caval vein at 0.53, and functionally univentricular heart with a totally anomalous pulmonary venous connection at 3.77. At a median follow-up of 124 months, the probability of survival was 87% for those with left, and 77% for those with right isomerism (P = .006). Conclusions: Multimodality imaging characterizes and delineates the relevant anatomical details, facilitating surgical management of individuals with isomeric atrial appendages. Continuing higher mortality despite surgical intervention in those with right isomerism points to the need for the reassessment of strategies for management.

Comparison of Different Tidal Volumes for Ventilation in Patients with an Acute Traumatic Cervical Spine Injury.

Background: There is scant literature comparing high tidal volume ventilation (HTV) over low tidal volume (LTV) ventilation in acute traumatic cervical spinal cord injury (CSCI). Objective: The aim of this prospective randomized controlled parallel-group, single-blinded study was to compare the effect of two different tidal volumes (12-15 mL/kg and 6-8 mL/kg) in CSCI on days to achieve ventilator-free breathing (VFB), PaO2/FIO2 ratio, the incidence of complications, requirement of vasopressor drugs, total duration of hospital stay, and mortality. Materials and Methods: We enrolled patients with acute high traumatic CSCI admitted to the neurotrauma intensive care unit within 24 h of injury, requiring mechanical ventilation. Participants were randomized to receive either HTV, 12-15 mL/kg (group H) or LTV, 6-8 mL/kg (group L) tidal volume ventilation. Results and Conclusions: A total of 56 patients, 28 in each group were analyzed. Patient demographics and injury severity were comparable between the groups. VFB was achieved in 23 and 19 patients in groups H and L, respectively. The median number of days required to achieve VFB was 3 (2, 56) and 8 (2, 50) days, P = 0.33; PaO2: FIO2 ratio was 364.0 ± 64 and 321.0 ± 67.0, P = 0.01; the incidence of atelectasis was 25% and 46%, P = 0.16, respectively, in group H and group L. The hemodynamic parameters and the vasopressor requirement were comparable in both groups. There was no barotrauma. The duration of hospital stay (P = 0.2) and mortality (P = 0.2) was comparable in both groups. There was no significant difference in days to achieve ventilator-free breathing with HTV (12-15 mL/kg) ventilation compared to LTV (6-8 mL/kg) ventilation in acute CSCI. The PaO2:FiO2 ratio was higher with the use of 12-15 mL/kg. No difference in mortality and duration of hospital stay was seen in either group.

Effects of Neurally Adjusted Ventilation Assist (NAVA) and conventional modes of mechanical ventilation on diaphragm functions: A randomized controlled trial.

BACKGROUND: Better patient-ventilator interactions, during neurally adjusted ventilator assist (NAVA), are expected to result in lower rate of diaphragm dysfunction. OBJECTIVE: This study was planned to compare the rate of diaphragm dysfunction between the conventional modes of mechanical ventilation and NAVA. METHODS: Patients who were initiated on mechanical ventilation for acute respiratory failure were randomized to continue either conventional mode of mechanical ventilation or switched to NAVA. The rates of diaphragm dysfunction were compared between two groups. RESULTS: This study included 46 participants (male 30/46) with a mean age of 58 years. Mean APACHE II and SOFA scores were 15 and 3, respectively. The mean (SD) diaphragm thickness fraction in the conventional mechanical ventilation and NAVA group were 37.12% (18.48) and 39.27% (27.65), respectively. The diaphragm dysfunction was observed in 5 (22.7%) and 8 (34.7%) patients in NAVA and conventional arm, respectively. There was no statistically significant difference between the two groups (p-value = 0.37). Diaphragm excursion was better in the NAVA group as compared with the conventional mechanical ventilation group. Diaphragm thickness and thickness fraction were comparable between two groups. CONCLUSION: Switching from the conventional mode of mechanical ventilation to NAVA leads to statistically non-significant reduction in the occurrence of diaphragm dysfunction. Adequately powered studies are required to assess the exact role of NAVA on diaphragm functions.

Effect of Multimodal Intervention (computer based cognitive training, diet and exercise) in comparison to health awareness among older adults with Subjective Cognitive Impairment (MISCI-Trial)-A Pilot Randomized Control Trial.

INTRODUCTION: This study was aimed to investigate the effect of multimodal intervention on the cognitive functions of older adults with subjective cognitive impairment (SCI). MATERIALS AND METHODS: Sixty subjects were randomized 1:1:1:1 to receive either computer based cognitive therapy (CBCT) or CBCT+Mediterranean equivalent diet (MED) or CBCT+MED+ Exercise regime and the control group. The intervention group received supervised CBCT twice a week to have 40 sessions, each of 40 minutes duration, and/ or supervised aerobic and resistive exercise twice a week for 24 weeks and or MED at home under the supervision of a dietician. The control group was provided with health awareness instructions for brain stimulating activities such as sudoku, mental maths, and learning music and new skills. RESULTS: Cognitive functions which was the primary outcome measure were assessed using the Post Graduate Institute Memory Scale (PGI-MS), and Stroop Colour and Word Test at baseline and after 6 months intervention period. As assessed by the PGI-MS, there was significant improvement in domains such as mental balance, attention and concentration, delayed recall, immediate recall, verbal retention of dissimilar pairs, Visual retention, and total score both in the unimodal and multimodal intervention groups. However, the improvement was observed to be the highest in the multimodal intervention group as compared to unimodal group. All the participants completed the trial. CONCLUSION: This pilot randomized control trial indicated that multimodal intervention could be an effective non-pharmacological intervention in individuals with SCI for improving their cognitive functions.

Diagnostic utility of chest computerized tomography in the diagnosis of recurrence among sputum scarce and sputum negative previously treated pulmonary tuberculosis suspects.

Objective: The objective was to study the sensitivity, specificity, and diagnostic accuracy of various computed tomography (CT) chest findings in diagnosing recurrence among pulmonary tuberculosis (PTB) suspects. Materials and Methods: A prospective observational study was conducted in a tertiary care hospital in New Delhi. A total of 130 suspects with a past history of treatment for PTB, who presented with any of the symptoms suggestive of recurrence were included. Sputum-positive, HIV-positive patients, pregnant females, and patients aged <18 years were excluded. Patients underwent CT chest followed by bronchoalveolar lavage (BAL). Results: A total of 62 patients were there in the final analysis. The median age of the patients with recurrent PTB was 27.5 years. Cough was the universal symptom in all these patients (>90%). Hemoptysis was the predominant symptom among patients with chronic pulmonary aspergillosis (66.6%). Necrotic mediastinal lymph nodes had good diagnostic accuracy of 88.71% with area under the curve of 0.806, P < 0.001 in diagnosing recurrent TB. BAL GeneXpert and mycobacteria growth indicator tube had good sensitivity (83.33% and 84.62%, respectively), specificity (100% for both), and excellent diagnostic accuracy (95.16% and 96.36%, respectively) for diagnosing recurrence in sputum negative and sputum scarce patient, (P < 0.001) when compared with composite reference standard. For culture-positive cases, BAL GeneXpert MTB/RIF had 100% sensitivity and 97.73% specificity in diagnosing recurrent PTB patients. Conclusion: The presence of mediastinal necrotic lymph node is the most accurate CT finding that can differentiate recurrent TB from post-TB sequelae. No other single chest CT scan finding had reliable diagnostic accuracy in comparison to microbiological tools in diagnosing recurrence among sputum negative or scarce previously treated PTB suspects.

Clinical Presentation and Course of SARS-CoV-2 Infection in Health-Care Personnel Working in Dedicated COVID-19 Hospital During 2 Pandemic Waves in India.

INTRODUCTION: Health-care personnel (HCPs) are predisposed to infection during direct or indirect patient care as well as due to the community spread of the disease. METHODS: We observed the clinical presentation and course of severe acute respiratory syndrome coronavirus disease 2 (SARS-CoV-2) infection in HCPs working in a dedicated coronavirus disease 2019 (COVID-19) care hospital during the first and the second wave. RESULTS: A total of 100 and 223 HCPs were enrolled for the first wave and the second wave, respectively. Cough, shortness of breath, sore throat, runny nose, and headache was seen in 40 (40%) and 152 (68%) (P < 0.01), 15 (15%) and 64 (29%) (P = 0.006), 40 (40%) and 119 (53.3%) (P = 0.03), 9 (9%) and 66 (30%) (P < 0.01), 20 (20%) and 125 (56%) (P < 0.01), respectively. Persistent symptoms at the time of joining back to work were seen in 31 (31%) HCPs and 152 (68%) HCPs, respectively (P ≤ 0.01). Reinfection was reported in 10 HCPs. CONCLUSIONS: Most of the HCPs had mild to moderate infections. Symptoms persist after joining back to work. Upgradation of home-based care and teleconsultation facilities for active disease and redressal of residual symptoms will be helpful.
