Background: The coronavirus disease (COVID-19) pandemic has significantly impacted healthcare services globally, with particular challenges observed in maternal and child health (MCH) care. This study aimed to assess the impact of the pandemic on MCH services in northern India, focusing on key government programs., Methods: Data were collected from four major MCH programs in India: Janani Suraksha Yojana (JSY), Janani Shishu Suraksha Karyakram (JSSK), Pradhan Mantri Surakshit Matritva Abhiyan (PMSMA), and the Universal Immunization Program (UIP). The study compared MCH service utilization and outcomes during the pandemic period (March-September 2020) with the same period in 2019., Results: Preliminary findings indicated a significant reduction in the utilization of MCH services during the pandemic, with a decrease observed in institutional deliveries, antenatal care visits, and immunization coverage. For instance, institutional deliveries declined by 30% compared with the previous year, with a similar decrease observed in antenatal care visits. Immunization coverage also decreased by approximately 25%, indicating a substantial decline in preventive care services. Challenges in accessing essential treatments for sick infants have also been reported, with a 40% decrease in the utilization of free treatment services under the JSSK program., Conclusion: The COVID-19 pandemic has substantially impacted MCH services in northern India, highlighting the vulnerability of these essential health programs during public health emergencies. Addressing the challenges identified in this study is crucial to ensuring the continuity and resilience of MCH services in similar settings., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Jain et al.)

G protein-coupled receptor 56 (GPR56/ADGRG1) is an adhesion GPCR with an essential role in brain development and cancer. Elevated expression of GPR56 was observed in the clinical specimens of Glioblastoma (GBM), a highly invasive primary brain tumor. However, we found the expression to be variable across the specimens, presumably due to the intratumor heterogeneity of GBM. Therefore, we re-examined GPR56 expression in public domain spatial gene expression data and single-cell expression data for GBM, which revealed that GPR56 expression was high in cellular tumors, infiltrating tumor cells, and proliferating cells, low in microvascular proliferation and peri-necrotic areas of the tumor, especially in hypoxic mesenchymal-like cells. To gain a better understanding of the consequences of GPR56 downregulation in tumor cells and other molecular changes associated with it, we generated a sh-RNA-mediated GPR56 knockdown in the GBM cell line U373 and performed transcriptomics, proteomics, and phospho-proteomics analysis. Our analysis revealed enrichment of gene signatures, pathways, and phosphorylation of proteins potentially associated with mesenchymal (MES) transition in the tumor and concurrent increase in cell invasion and migration behavior of the GPR56 knockdown GBM cells. Interestingly, our analysis also showed elevated expression of Transglutaminase 2 (TG2) - a known interactor of GPR56, in the knockdown cells. The inverse expression of GPR56 and TG2 was also observed in intratumoral, spatial gene expression data for GBM and in GBM cell lines cultured in vitro under hypoxic conditions. Integrating all these observations, we propose a putative functional link between the inverse expression of the two proteins, the hypoxic niche and the mesenchymal status in the tumor. Hypoxia-induced downregulation of GPR56 and activation of TG2 may result in a network of molecular events that contribute to the mesenchymal transition of GBM cells, and we propose a putative model to explain this functional and regulatory relationship of the two proteins., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Ganesh, Sonpatki, Naik, John, Sathe, Lakshmikantha, Chandrachari, Bauer, Knäuper, Aeschlimann, Venkatraaman, Shah and Sirdeshmukh.)

Glioblastoma is the most lethal primary malignant brain tumor in adults. Simplified two-dimensional (2D) cell culture and neurospheres in vitro models fail to recapitulate the complexity of the tumor microenvironment, limiting its ability to predict therapeutic response. Three-dimensional (3D) scaffold-based models have emerged as a promising alternative for addressing these concerns. One such 3D system is gelatin methacrylate (GelMA) hydrogels, and we aimed to understand the suitability of using this system to mimic treatment-resistant glioblastoma cells that reside in specific niches. We characterized the phenotype of patient-derived glioma cells cultured in GelMA hydrogels (3D-GMH) for their tumorigenic properties using invasion and chemoresponse assays. In addition, we used integrated single-cell and spatial transcriptome analysis to compare cells cultured in 3D-GMH to neoplastic cells in vivo. Finally, we assessed tumor-immune cell interactions with a macrophage infiltration assay and a cytokine array. We show that the 3D-GMH system enriches treatment-resistant mesenchymal cells that are not represented in neurosphere cultures. Cells cultured in 3D-GMH resemble a mesenchymal-like cellular phenotype found in perivascular and hypoxic regions and recruit macrophages by secreting cytokines, a hallmark of the mesenchymal phenotype. Our 3D-GMH model effectively mimics the phenotype of glioma cells that are found in the perivascular and hypoxic niches of the glioblastoma core in situ, in contrast to the neurosphere cultures that enrich cells of the infiltrative edge of the tumor. This contrast highlights the need for due diligence in selecting an appropriate model when designing a study's objectives., (© 2021. The Author(s).)

Gliomas are heavily infiltrated with immune cells of myeloid origin. Past studies have shown that high-grade gliomas have a higher proportion of alternatively activated and suppressive myeloid cells when compared to low-grade gliomas, which correlate with poor prognosis. However, the differences in immune cell phenotypes within high-grade gliomas (between grade 3 and grade 4 or GBM) are relatively less explored, and a correlation of phenotypic characteristics between immune cells in the blood and high-grade tumors has not been performed. Additionally, myeloid cells of granulocytic origin present in gliomas remain poorly characterized. Herein, we address these questions through phenotypic characterizations of monocytes and neutrophils present in blood and tumors of individuals with glioblastoma (GBM, IDH-wild type) or grade 3 IDH-mutant gliomas. We observe that neutrophils are highly heterogeneous among individuals with glioma, and are different from healthy controls. We also show that CD163 expressing M2 monocytes are present in greater proportions in GBM tissue when compared to grade 3 IDH-mutant glioma tissue, and a larger proportion of granulocytic myeloid-derived suppressor cells are present in grade 3 IDH-mutant gliomas when compared to GBM. Finally, we demonstrate that the expression levels of CD86 and CD63 showed a high correlation between blood and tumor and suggest that these may be used as possible markers for prognosis., Competing Interests: The authors have no conflict of interest., (© 2021 The Author(s).

A novel natural hydroxyapatite (HAp) bioceramic was extracted from the ostrich cortical bone by the thermal decomposition method. HAp was characterized by different analytical tools such as thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM). Removal of organic impurities from the bone powder was confirmed by TGA analysis. FTIR spectra of HAp confirmed the presence of the major functional groups such as phosphate (PO 4 3- ), hydroxyl (OH - ), and carbonate (CO 3 2- ) in the bioceramic. The XRD data revealed that the HAp was the crystalline phase obtained by calcination of the bone powder at 950°C, and the SEM analyses confirmed the typical plate-like texture of the nanosized HAp crystals., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Komal Prasad Malla et al.)

Cervical spondylotic myelopathy (CSM) is a common cause of adult spinal cord dysfunction. Although the therapeutic options for moderate to severe CSM patients have been established well, the existing guidelines for therapeutic decisions in mild cases of CSM are unclear. We present a review of literature on conservative treatment and surgery for CSM and suggest general recommendations applicable in various clinical presentations and in different geographic locations across the globe, with due considerations to available resources and locally prevalent practices.

The objective of the study was to determine the causes of lactation failure (LF), factors affecting relactation in mothers having low milk supply (LMS) and LF, and to know the success rate of relactation by proper counselling and positive support group. It was a prospective hospital-based study conducted in tertiary care referral hospital in mothers with their biological infants of less than 4 months of age, who were admitted with LF and some breastfeeding (BF) related problems. Mothers were advised for frequent BF in proper position and good attachment under supervision of trained BF experts with good support group. Lactogogue was used in few mothers. There were 64 mothers with LF and LMS, out of them 45 (70.3%) were between the age of 21-35 years. Maximum infants ( n = 51, 79.69%) were below 6 weeks of age; and in 32 (78.04%) infants, artificial feeding was started within 15 days of postnatal life. Commonest cause of LF was mother's misconception of insufficient milk ( n = 25, 39%). Relactation was possible in 100% mothers. Complete relactation was possible in 29 (85.29%) mothers when their age was <25 years and in 38 (86.36%) mothers when their infants age was <6 weeks. Chances of complete relactation were less, when duration of artificial feeding was more and infant was fed with bottle (62.96%). We found no difference with the use of lactogogue. Relactation was possible in 100% of mothers (may be partial) by continuous and positive support from family members and trained health workers.

Aim: The present experiment was conducted to study the effect of post hatch dietary fat supplementation on performance of broiler chicken., Materials and Methods: A total of 120 day-old Ven Cobb broiler chicks were randomly assigned to 4 treatment groups of 30 chicks in each (three replicates of 10 birds/treatment). The trial lasted for 35 days. The experimental design was a completely randomized design. Four types of diet were formulated for 1(st) week: T1, T2, T3 and T4 contained control diet with no added fat, 2.5, 5 and 7.5% fat, respectively. After 1(st) week post-hatch period chicks were fed ad libitum with the normal basal diet as per Bureau of Indian Standard recommendations till completion of the experiment (8-35 days)., Results: Significantly higher (p<0.05) body weight and improved feed conversion ratio (FCR) was recorded in birds fed 5% dietary fat at the end of the experiment whereas, feed intake was not significantly affected. Significantly (p<0.05) higher dressed weight was observed due to 5% fat supplementation than other groups whereas, it was not significant for other carcass cuts. No significant differences were observed in moisture, protein and lipid content of breast and thigh muscle of broiler due to supplemented fat whereas, 2.5% dietary fat significantly (p<0.05) increase the serum HI titer on day 28(th). In biochemical profile, higher serum albumin (g/dl) was recorded due to 5% fat supplementation whereas other biochemical components did not show any significance difference among treatments., Conclusion: It may be concluded that supplementation of fat in broilers diet improves the overall FCR, dressing percentage and gain more body weight.
