Comparison of inflammatory markers in low-pressure pneumoperitoneum with deep neuromuscular block versus standard pressure pneumoperitoneum among patients undergoing laparoscopic cholecystectomy for gallstone disease: a randomized control trial.

BACKGROUND: Low-pressure pneumoperitoneum (LPP) is an attempt to improve laparoscopic surgery. Lower pressure causes lesser inflammation and better hemodynamics. There is a lack of literature comparing inflammatory markers in LPP with deep NMB to standard pressure pneumoperitoneum (SPP) with moderate NMB in laparoscopic cholecystectomy. METHODOLOGY: This was a single institutional prospective randomized control trial. Participants included all patients undergoing laparoscopic cholecystectomy for symptomatic gall stone disease. Participants were divided into 2 groups group A and B. Group A-Low-pressure group in which pneumoperitoneum pressure was kept low (8-10 mmHg) with deep Neuromuscular blockade (NMB) and Group B-Normal pressure group (12-14 mmHg) with moderate NMB. A convenience sample size of 80 with 40 in each group was selected. Lab investigations like CBC, LFT, RFT and serum IL-1, IL-6, IL-17, TNF alpha levels were measured at base line and 24 h after surgery and compared using appropriate statistical tests. Other parameters like length of hospital stay, post-operative pain score, conversion rate (low-pressure to standard pressure), and complications were also compared. RESULTS: Eighty participants were analysed with 40 in each group. Baseline characteristics and investigations were statistically similar. Difference (post-operative-pre-operative) of inflammatory markers were compared between both groups. Numerically there was a slightly higher rise in most of the inflammatory markers (TLC, ESR, CRP, IL-6, TNFα) in Group B compared to Group A but not statistically significant. Albumin showed significant fall (p < 0.001) in Group B compared to Group A. Post-operative pain was also significantly less (p < 0.001) in Group A compared to Group B at 6 h and 24 h. There were no differences in length of hospital stay and incidence of complications. There was no conversion from low-pressure to standard pressure. CONCLUSION: Laparoscopic cholecystectomy performed under low-pressure pneumoperitoneum with deep NMB may have lesser inflammation and lesser post-operative pain compared to standard pressure pneumoperitoneum with moderate NMB. Future studies with larger sample size need to be designed to support these findings.

Quality of life and swallowing outcomes following major glossectomy: A prospective single-center experience.

BACKGROUND: There exists a lacuna in the structured reporting of swallowing dysfunction and quality of life (QoL) outcome following major glossectomy. METHODS: Prospective cohort study to assess the swallowing dysfunction and QoL following STG (subtotal glossectomy) or NTG (near total glossectomy) over a 6-month period using FEES and PAS scale, MDADI, and FACT-HN. RESULTS: Twenty-four patients were available for analysis. The pre- and post-adjuvant evaluation revealed a statistically significant improvement in the composite MDADI and FACT-HN scores. Subscale analysis of FACT-HN scores revealed maximum deficit in the head and neck cancer-specific score domain followed by functional domain and social well-being domain, with serial improvement noted in the post-adjuvant setting. CONCLUSION: This study showed serial improvement in terms of swallowing dysfunction although social and functional well-being domains related to QoL continued to reveal major deficits. Better outcomes were seen with preservation of bilateral base of tongue and mandible.

Timeliness in the uptake of hepatitis B birth dose among Indian children under age five: A population-based study.

OBJECTIVE: To assess the timeliness and risk factors for the delay in the uptake of the hepatitis B birth dose among Indian children aged 0-59 months. Information regarding whether the children received the birth dose and the time of receiving it was recorded based on the vaccination card available at the time of the National Family Health Survey (NFHS). METHODS: Using data from the fourth and fifth round of India's National Family Health Survey (NFHS), the percentage of uptake and timely receipt of the hepatitis B birth dose were obtained by background characteristics and at the sub-national level (state). Multinomial logistic regression analysis was used to examine the risk factors. This study further performed a negative binomial regression estimation to predict the probability of receiving the birth dose at each day within a multivariable framework. RESULTS: It was found that approximately 34 % of the children who received the birth dose and the timing of receiving the birth dose was made available through the vaccination card were administered the dose within 24-hours during 2015-16. However, the percentage increased to 51.91 % during 2019-21. During 2019-21, Ladakh had the highest proportion (85.03 %) of children receiving the dose within 24-hours, followed by Jammu & Kashmir with 78 %, and Arunachal Pradesh with 68 %. Mother's education, economic status of the child's family and region (children belong from) were found to be significant predictors in delay of receiving the birth dose within 24 hours. CONCLUSION: Results indicated a need for targeted interventions to improve the coverage and timeliness in the uptake of this critical vaccine dose in the country. These interventions could include strategies such as strengthening the healthcare system, improving awareness among parents and healthcare providers, addressing logistical challenges in vaccine delivery, and promoting community engagement and education on importance of timely vaccination.

Fabrication of gold nanoparticles tethered in heat-cooled calf thymus-deoxyribonucleic acid Langmuir-Blodgett film as effective surface-enhanced Raman scattering sensing platform.

SERS active substrate fabricated through self-assembly of Gold nanoparticles on the disjointed networks of Heat-cooled Calf Thymus DNA (HC-Ct DNA) Langmuir-Blodgett (LB) film has been reported. Adsorption kinetics of HC-Ct DNA molecules at the air-water interface has been studied explicitly. The UV-Vis electronic absorption spectra in conjunction with the FESEM images collectively suggest the presence of H- type aggregated domains most likely owing to plane-to-plane self-association of the HC-Ct DNA molecules aligned vertically on the surface of the LB film. Elemental composition and the morphological features of the as-prepared substrate (APS) are explored from XPS analysis and the FESEM, AFM images respectively. The SERS efficacy of the APS has been tested with trace concentrations of 4-Mercaptopyridine molecule. Finally, this SERS active substrate has also been used for the detection of malathion at ultrasensitive concentrations.

Re-examining Psychometric Properties of Fertility Problem Inventory: A Clinic-Based Study from India.

Background: The fertility problem inventory (FPI) is one of the most widely used measures that tap the diverse psychological problems faced by infertile couples. Research on translated versions of FPI has also reflected its high clinical significance. Aim: This research aimed to explore the psychometric properties and the clinical validity of the original 46-item FPI in an Indian sample. Setting and Design: This cross-sectional study was conducted in a tertiary hospital setup of a medical college. Materials and Methods: The original FPI was translated and pilot tested. The translated FPI was taken by 205 consenting infertile patients (113 women and 92 men). The psychometric properties of FPI were thus explored. Statistical Analysis: Exploratory factor analysis with minimum residual method of extraction followed by oblimin rotation was performed. Perceived Stress Scale was used to establish the convergent validity of the newly developed FPI-Kannada version (FPI-K). A cut-off score for the FPI-K was obtained separately for males and females using ROC analysis in which hamilton anxiety scale was used as the gold standard. Results: Only 32 items of the original FPI had factor loadings above 0.3 and overall six factors explained these items with a cumulative percentage variation of 32%. Overall Cronbach's alpha for FPI-K was 0.671 and it had a good convergent validity. Conclusions: The new FPI-K had 6 sub-domains and the clinical utility of same is discussed.

Variations within Toll-like receptor (TLR) and TLR signaling pathway-related genes and their synergistic effects on the risk of Guillain-Barré syndrome.

Guillain-Barré syndrome (GBS) is the commonest post-infectious polyradiculopathy. Although genetic background of the host seems to play an important role in the susceptibility to GBS, genes conferring major risk are not yet known. Dysregulation of Toll-like receptor (TLR) molecules exacerbates immune-inflammatory responses and the genetic variations within TLR pathway-related genes contribute to differential risk to infection. The aim of this study was to delineate the impact of genetic variations within TLR2, TLR3, and TLR4 genes as well as TLR signaling pathway-related genes such as MyD88, TRIF, TRAF3, TRAF6, IRF3, NFκß1, and IκBα on risk of developing GBS. Fourteen polymorphisms located within TLR2 (rs3804099, rs111200466), TLR3 (rs3775290, rs3775291), TLR4 (rs1927911, rs11536891), MyD88 (rs7744, rs4988453), TRIF (rs8120), TRAF3 (rs12147254), TRAF6 (rs4755453), IRF3 (rs2304204), NFκß1 (rs28362491), and IκBα (rs696) genes were genotyped in 150 GBS patients and 150 healthy subjects either by PCR-RFLP or TaqMan Allelic Discrimination Assay. Genotypes of two polymorphic variants, Del/Del of rs111200466 insertion and deletion (INDEL) polymorphism of TLR2 gene and TT of rs3775290 single nucleotide polymorphism (SNP) of TLR3 gene had significantly higher frequencies among GBS patients, while the frequencies of TT genotype of rs3804099 SNP of TLR2 gene and TT genotype of rs11536891 SNP of TLR4 gene were significantly higher in controls. Gene-gene interaction study by Multifactor Dimensionality Reduction analysis also suggested a significant combined effect of TLR2, and NFκß1 genes on the risk of GBS. The SNPs in the IκBα and IRF3 genes correlated with severity of GBS. The genes encoding TLRs and TLR signaling pathway-related molecules could serve as crucial genetic markers of susceptibility and severity of GBS.

Towards the Segmentation and Classification of White Blood Cell Cancer Using Hybrid Mask-Recurrent Neural Network and Transfer Learning.

Inside the bone marrow, plasma cells are created, and they are a type of white blood cells. They are made from B lymphocytes. Antigens are produced by plasma cells to combat bacteria and viruses and prevent inflammation and illness. Multiple myeloma is a plasma cell cancer that starts in the bone marrow and causes the formation of abnormal plasma cells. Multiple myeloma is firmly identified by examining bone marrow samples under a microscope for myeloma cells. To diagnose myeloma cells, pathologists have to be very selective. Furthermore, because the ultimate decision is based on human sight and opinion, there is a possibility of error in the result. The nobility of this research is that it provides a computer-assisted technique for recognizing and detecting myeloma cells in bone marrow smears. For recognizing purposes, we have used Mask-Recurrent Convolutional Neural Network, and for detection purposes, Efficient Net B3 has been used. There are already many studies on white blood cell cancer, but very few with both segmentation and classification. We have designed two models. One is for recognizing myeloma cells, and the other is for differentiating them from nonmyeloma cells. Also, a new data set has been made from the multiple myeloma data sets, which has been used in our classification model. This research focuses on hybrid segmentation models and increases the accuracy level of the classification model. Both of our models are trained pretty well, where the Mask-RCNN model gives a mean average precision (mAP) of 93% and the Efficient Net B3 model gives 94.68% accuracy. The result of this research indicates that the Mask-RCNN model can recognize multiple myeloma and Efficient Net B3 can distinguish between myeloma and nonmyeloma cells and beats most of the state of the art in myeloma recognition and detection.

Antecedent infections in Guillain-Barré syndrome patients from south India.

Guillain-Barré syndrome (GBS) is the commonest post-infectious inflammatory peripheral neuropathy with undiscerned aetiology. The commonly reported antecedent infections implicated in India include Campylobacter jejuni, chikungunya, dengue, and Japanese encephalitis (JE). In this study from south India, we investigated the role of these four agents in triggering GBS. This case-control study was performed on 150 treatment-naive patients with GBS and 150 age and sex-matched controls from the same community. IgM immunoreactivity for C. jejuni, chikungunya, and dengue was detected by enzyme-linked immunosorbent assay (ELISA) in serum of patients with GBS and control subjects. Immunoreactivity against JE was detected in serum as well as cerebrospinal fluid (CSF) from patients (n = 150) and orthopaedic control (n = 45) subjects. The immunoreactivity against infections was compared between demyelinating and axonal subtypes of GBS. Overall, 119/150 patients with GBS had serological evidence of antecedent infection. Amongst those with evidence of antecedent infection, 24 (16%), 8 (5%), and 9 (6%) patients were exclusively immunoreactive to chikungunya, JE, and C. jejuni, respectively. In the remaining patients (78/119), immunoreactivity to multiple pathogens was noted. Immunoreactivity to C. jejuni infection was found in 32% of GBS patients compared to 2.7% controls (P < .001), whereas to chikungunya virus was reported in 66.7% of patients with GBS compared to 44.7% controls (P = .006). Anti-dengue immunoreactivity was significantly associated with the demyelinating subtype of GBS. Patients positive for JE IgM (CSF) manifested demyelinating electrophysiology. In this large case-control study, immunoreactivity against multiple infectious agents was observed in a subset of patients. Chikungunya was the commonest antecedent infection, followed by C. jejuni.

The burden of anthropometric failure and child mortality in India.

The public health burden of nutritional deficiency and child mortality is the major challenge India is facing upfront. In this context, using National Family Health Survey, 2015-16 data, this study estimated rate of composite index of anthropometric failure (CIAF) among Indian children by their population characteristics, across states and examined the multilevel contextual determinants. We further investigated district level burden of infant and child mortality in terms of multiple anthropometric failure prevalence across India. The multilevel analysis confirms a significant state, district and PSU level variation in the prevalence of anthropometric failures. Factors like- place of residence, household's economic wellbeing, mother's educational attainment, age, immunization status and drinking water significantly determine the different forms of multiple anthropometric failures. Wealth status of the household and mother's educational status show a clear gradient in terms of the estimated odds ratios. The district level estimation of infant and child mortality demonstrates that districts with higher burden of multiple anthropometric failures show elevated risk of infant and child mortality. Unlike previous studies, this study does not use the conventional indices, instead considered the CIAF to identify the exact and severe form of undernutrition among Indian children and the associated nexus with infant and child mortality at the district level.

COVID-19-Hospitalized Patients in Karnataka: Survival and Stay Characteristics.

The information on the clinical course of coronavirus disease 2019 (COVID-19) and its correlates which are essential to assess the hospital care needs of the population are currently limited. We investigated the factors associated with hospital stay and death for COVID-19 patients for the entire state of Karnataka, India. A retrospective-cohort analysis was conducted on 445 COVID-19 patients that were reported in the publicly available media-bulletin from March 9, 2020, to April 23, 2020, for the Karnataka state. This fixed cohort was followed till 14 days (May 8, 2020) for definitive outcomes (death/discharge). The median length of hospital stay was 17 days (interquartile range: 15-20) for COVID-19 patients. Having severe disease at the time of admission (adjusted-hazard-ratio: 9.3 (3.2-27.3);P < 0.001) and being aged ≥ 60 years (adjusted-hazard-ratio: 11.9 (3.5-40.6);P < 0.001) were the significant predictors of COVID-19 mortality. By moving beyond descriptive (which provide only crude information) to survival analyses, information on the local hospital-related characteristics will be crucial to model bed-occupancy demands for contingency planning during COVID-19 pandemic.

Deciphering the near-field response with the far-field wavelength-scanned SERS spectra of 4-mercaptopyridine adsorbed on gold nanocolloidal particles entrapped in Langmuir Reverse Schaefer film of 5CB liquid crystal molecules.

Herein, we have reported the wavelength-scanned (WS) SERS spectra of 4-mercaptopyridine molecules (4-MPy) adsorbed on gold nanoparticles immobilised in a Langmuir Reverse Schaefer (L-RSh) film matrix of 5CB molecules. The WS-SERS spectral profile exhibited an increment in the intensity of the enhanced Raman bands of 4-MPy with an increase in the wavelength of the excitation laser source. The rationale behind the experimental observations was supported by the simulated extinction spectra and the enhancement factor measurements of the modelled systems using the T-matrix formalism. The SERS intensity fluctuations in the band located at 1000 cm-1 for the 4-MPy molecule, as obtained from three different locations in the L-RSh film substrate, were also analyzed. Surprisingly, depending on the spatial locations of the substrates, the intensity fluctuations of the abovementioned band exhibit both Poisson and Gaussian distributions but the maximum number of probe molecules that can reside in the scattering areas under investigation cannot exceed sixteen. These observations suggest that the origin of SERS from single/few molecules or from the ensemble-averaged system cannot be inferred from the statistical distributions of the Raman intensity fluctuations. The present experimental observations also revealed the relation between the near-field plasmonic behaviors of the substrate with the corresponding far-field SERS spectra of the 4-MPy molecule.

Why is the inpatient cost of dying increasing in India?

INTRODUCTION: There is an evidence of increasing inpatient expenditure for decedents. Estimates used to assess the economic burden of out-of-pocket (OOP) healthcare expenditure provide an underestimation for inpatient decedent cases. The aims of this paper are to study the trend and pattern of inpatient decedent expenditure and decipher the reasons behind the increasing cost in India. METHODS: Using three rounds of national level National Sample Survey (NSS) data on morbidity & healthcare conducted during 1995-2015 in India, total and component-wise cost of dying was estimated by the socio-demographic characteristics and types of diseases. Generalised linear model was employed to find the changing effect of inpatient decedents on inpatient expenditure on three-time points. RESULTS: More than half among inpatient decedents were elderly. Mean inpatient expenditure for neoplasm, circulatory system-related diseases and external causes of mortality and morbidity increased substantially during these two decades. Mean decedent inpatient expenditure become double, diagnostic and bed charges increased by 243%, 323% respectively during 2004-05 to 2014-15. During 2014-15 average decedents aged 15-59 years spent ₹53599 in last twelve month of their life. Controlling all other potential factors, the inpatient expenditure among decedents increased substantially between 1995-96 and 2014-15. DISCUSSION: Out-of-pocket inpatient health expenditure widened between survivor and decedents in between 1995-2014. Increase in the proportion of elderly, proportion of non-communicable and lifestyle-related diseases, expenses on drugs, diagnostics, bed charges largely private sector expenses were the leading reasons for increasing inpatient decedent expenditure. Age-based risk adjustment and modification of end-of-life care are strongly required, future social insurance based on the health-based value of out-of-pocket expenditure rather than their pure consumption value need to be designed to tackle the burden.
