RESUMEN
Mental well-being is now an increasingly researched and discussed topic that primarily involves taking care of mental health in a preventive manner and is more of a subjective concept. Mental well-being ensures mental health and measures taken toward it can protect the person's overall health. Discussing and researching this concept is of paramount importance as this will not just safeguard an individual life but the society at large. The lifetime of a woman is multidimensionally unique with a complex interplay of biological, sociocultural, and environmental aspects. This demands a diverse variety of factors required to ensure mental well-being in a woman. In addition to this, these determinants vary on the life stage the woman is in. Factors that influence this well-being are also specific when it comes to an Indian context. This chapter considers and discusses in detail the various aspects of the mental health and well-being of women in the pubertal, perinatal, and menopausal age groups. Determinants are unique to particular age groups of women, and measures to focus on and ensure it will be elaborated on. Finally, recommendations towards policy making are also suggested.
RESUMEN
Colorectal carcinoma (CRC) is the third most common cancer worldwide. Along with many established prognostic factors, tumor budding is emerging as a valuable marker of prognosis. Tumor budding is not yet universally reported but it has recently been suggested in guidelines by ITBCC (International Tumor Budding Consensus Conference). Our aim is to study prognostic implications of tumor budding in CRC. Hundred cases of primary CRC specimens were retrospectively studied from January, 2016, to February, 2017. Tumor bud count and other histopathological parameters were evaluated from hematoxyline and eosin (H & E) stained slides. Survival analysis was done using Cox proportional hazards model. Association of tumor budding and cancer-specific survival was found to be statistically significant (P = 0.018 for average tumor budding and P = 0.035 for highest tumor budding) Tumor budding was found to be significantly associated with other clinicopathological parameters such as T stage, N stage, TNM stage, and lymphovascular invasion with p value < 0.05. Tumor budding is a valuable prognostic indictor for primary CRC and also significantly associated with other prognostic parameters. It should be reported routinely as a guide to prognosis and further management of patients.
RESUMEN
Background: Neurocognitive deficits are well-documented in patients of schizophrenia and their first-degree relatives (FDRs). Metacognitive awareness of these deficits, called neurocognitive insight (NI), has been found to be poor in schizophrenia patients but has not been assessed in their FDRs. This study evaluated NI and its relationship with objective cognitive performance, a history of psychotic experiences (PEs), and social functioning in unaffected FDRs. Methods: This cross-sectional study was conducted at the outpatient department of a tertiary care teaching hospital. A total of 100 FDRs were assessed for PEs and evaluated for subjective cognitive complaints (SCC), objective cognitive performance, and social functioning using the Subjective Scale to Investigate Cognition in Schizophrenia, neurocognitive tests from the National Institute of Mental Health and Neurosciences battery, and SCARF Social Functioning Index, respectively. Results: Compared to normative data, episodic memory was the most commonly impaired domain (up to 72% of participants), followed by working memory, attention, and executive function. There was no correlation between SCC and neuropsychological test scores in the corresponding cognitive domains, implying poor NI. 15% of participants had a lifetime history of PEs. This group had significantly higher SCC as compared to those without PEs (U = 0.366, P = 0.009, r = 0.26). A regression analysis showed that the FDRs' social functioning reduced by 0.178 units for each unit increase in SCC [F (1,98) = 5.198, P = 0.025]. Conclusion: Similar to schizophrenia patients, FDRs also have poor NI. The severity and progression of SCC could be explored as a possible marker for screening and monitoring FDRs at an ultrahigh risk for psychosis. Importantly, even in unaffected FDRs, SCC could affect socio-occupational functioning and need further research.

RESUMEN
CONTEXT: Malignant peripheral nerve sheath tumor (MPNST) is a rare and aggressive soft-tissue sarcoma. AIMS: The aim of this study was to analyze various prognostic factors and treatment outcome of patients with MPNST. SETTINGS AND DESIGN: This was a retrospective study. SUBJECTS AND METHODS: Ninety-two patients, who presented with MPNST at a tertiary care cancer center from 2011 to 2018, were included in this study. The median follow-up of all living patients was 33 months. Neurofibromatosis 1 (NF1) was seen in 12 (13%) patients. Sixty (65.2%) patients received curative-intent treatment. STATISTICAL ANALYSIS USED: Kaplan-Meier method was used for survival analysis. Log-rank test was used for univariate analysis, and multivariate analysis was done by Cox proportional hazard ratio method. RESULTS: The 5-year overall survival (OS) of all patients was 47.2% and the 5-year disease-free survival (DFS) of operated patients was 41.5%. On univariate analysis, association with NF1 (P = 0.009), grade (P = 0.017), and margin status (P = 0.002) had a significant effect on DFS, whereas association with NF1 (P = 0.025), metastatic disease on presentation (P < 0.0001), palliative intent of treatment (P < 0.0001), grade (P = 0.049), and margin status (P = 0.036) had a significant effect on OS. On multivariate analysis for patients who were treated with curative-intent treatment, grade (P = 0.015), and margin status (P = 0.028) had a significant effect on DFS, whereas association with NF1 (P = 0.00026) and location of tumor (P = 0.040) had a significant effect on OS. CONCLUSIONS: The presence of distant metastasis, palliative intent of treatment, association with NF1, location of the tumor in the head and neck, high tumor grade, and positive margin status were the risk factors associated with poor survival for the patients with MPNST. Wide local excision with negative resection margin is the highly recommended treatment.

CONTEXT: Neurocognitive deficits are well documented in schizophrenia. Neurocognitive insight (NI), described as awareness of neurocognitive deficits, has not been evaluated in the Indian context. Its relation to clinical profile and social functioning also remains unexplored. AIMS: The aim of this study was to evaluate the subjective cognitive complaints (SCCs) and their relation to objective cognitive performance, clinical profile, clinical insight, and social functioning in patients of schizophrenia. SETTINGS AND DESIGN: This was a cross-sectional study at the outpatient department of a tertiary care teaching hospital. MATERIALS AND METHODS: One hundred individuals with schizophrenia were evaluated using Positive and Negative Syndrome Scale, Subjective Scale To Investigate Cognition in Schizophrenia, abbreviated version of Scale to Assess Unawareness in Mental Disorders, and Schizophrenia Research Foundation-Social Functioning Index. Cognitive performance was assessed using (1) Digit Span Test (attention) from Wechsler Adult Intelligence Scale, 3rd edition and (2) Passages Test (explicit memory), (3) Verbal n-back Test (working memory), and (4) Stroop Test (executive functioning) from the National Institute of Mental Health and Neuro Sciences Battery. STATISTICAL ANALYSIS: Statistical analysis was done using descriptive statistics, nonparametric tests, and Pearson's coefficient of correlation. RESULTS: Participants showed impairment in all cognitive domains. Except for working memory, there was no correlation between SCC and objective performance for other cognitive domains correspondingly, implying poor NI. Severity of psychosis and clinical insight did not have any correlation with SCC. Higher SCC correlated with poorer social functioning, especially in "occupational" and "other social roles" domains. CONCLUSIONS: Individuals with schizophrenia have poor NI. This is independent of severity of psychosis or clinical insight into illness. Socio-occupational functioning and depression should be actively enquired into when patients present with SCC.
RESUMEN
Hybrid tissue engineered (HTE) scaffolds constituting polymeric nanofibers and biological tissues have attractive bio-mechanical properties. However, they suffer from small pore size due to dense overlapping nanofibers resulting in poor cellular infiltration. In this study, using nanosecond (ns) laser, we fabricated micro-scale features on Polycaprolactone (PCL)-Chitosan (CH) nanofiber layered bovine pericardium based Bio-Hybrid scaffold to achieve enhanced cellular adhesion and infiltration. The laser energy parameters such as fluence of 25J/cm2, 0.1mm instep and 15 mark time were optimized to get structured microchannels on the Bio-Hybrid scaffolds. Laser irradiation time of 40µs along with these parameters resulted in microchannel width of ~50µm and spacing of ~35µm between adjacent lines. The biochemical, thermal, hydrophilic and uniaxial mechanical properties of the Bio-Hybrid scaffolds remained comparable after laser ablation reflecting extracellular matrix (ECM) stability. Human umbilical cord mesenchymal stem cells and mouse cardiac fibroblasts seeded on these laser-ablated Bio-Hybrid scaffolds exhibited biocompatibility and increased cellular adhesion in microchannels when compared to non-ablated Bio-Hybrid scaffolds. These findings suggest the feasibility to selectively ablate polymer layer in the HTE scaffolds without affecting their bio-mechanical properties and also describe a new approach to enhance cellular infiltration in the HTE scaffolds.

BACKGROUND: Sub typing of non small cell lung carcinoma (NSCLC) has an important task in the era of molecular and targeted therapies. Differentiating between squamous cell carcinoma (SQCC) and adenocarcinoma (ADC) is challenging when limited material is available in lung carcinoma. We investigated the accuracy and feasibility of sub typing NSCLCs in cytology and small biopsy material. METHODS: Concurrent cytology and biopsy material obtained in a single CT- guided procedure in lung carcinoma over a year period retrospectively. Both materials were individually sub typed and analyzed. Immunohistochemistry (IHC) was performed. Accuracy was determined by comparing the results with IHC. RESULTS: Total 107 of 126 cases of NSCLCs were included for analysis, where both cytology and biopsy material were adequate for interpretation. FNAC allowed tumor typing in 83 (77.6%) cases; 36 (33.6%) were ADC, 47 (43.9%) cases were SQCC and 24 (22.4%) cases diagnosed as Non-small cell carcinoma not otherwise specified (NSCLC-NOS). In biopsy, 86 cases (80.4%) were typed, among which 34 (31.8%) were ADC, 52 (48.6%) were SQCC and 21 (19.6%) were of NSCLC-NOS type. The result of Chi-square index was significant. With the aid of IHC, NSCLC-NOS reduced from 14 (13%) cases to 2 (1.9%) cases. CONCLUSION: Cytology and small biopsy specimens achieved comparable specificity and accuracy in sub-typing NSCLC and optimal results were obtain when findings from both modalities combine. The advantage of paired specimens is to maximize overall diagnostic yield and the remaining material will be available for ancillary technique like IHC or for molecular testing. Diagn.

Major challenge in heart valve tissue engineering for paediatric patients is the development of an autologous valve with regenerative capacity. Hybrid tissue engineering approach is recently gaining popularity to design scaffolds with desired biological and mechanical properties that can remodel post implantation. In this study, we fabricated aligned nanofibrous Bio-Hybrid scaffold made of decellularized bovine pericardium: polycaprolactone-chitosan with optimized polymer thickness to yield the desired biological and mechanical properties. CD44+, αSMA+, Vimentin+ and CD105- human valve interstitial cells were isolated and seeded on these Bio-Hybrid scaffolds. Subsequent biological evaluation revealed interstitial cell proliferation with dense extra cellular matrix deposition that indicated the viability for growth and proliferation of seeded cells on the scaffolds. Uniaxial mechanical tests along axial direction showed that the Bio-Hybrid scaffolds has at least 20 times the strength of the native valves and its stiffness is nearly 3 times more than that of native valves. Biaxial and uniaxial mechanical studies on valve interstitial cells cultured Bio-Hybrid scaffolds revealed that the response along the axial and circumferential direction was different, similar to native valves. Overall, our findings suggest that Bio-Hybrid scaffold is a promising material for future development of regenerative heart valve constructs in children.

Current treatment strategy for end stage valve disease involves either valvular repair or replacement with homograft/mechanical/bioprosthetic valves. In cases of recurrent stenosis/ regurgitation, valve replacement is preferred choice of treatment over valvular repair. Currently available mechanical valves primarily provide durability whereas bioprosthetic valves have superior tissue compatibility but both lack remodelling and regenerative properties making their utility limited in paediatric patients. With advances in tissue engineering, attempts have been made to fabricate valves with regenerative potential using various polymers, decellularized tissues and hybrid scaffolds. To engineer an ideal heart valve, decellularized bovine pericardium extracellular matrix (DBPECM) is an attractive biocompatible scaffold but has weak mechanical properties and rapid degradation. However, DBPECM can be modified with synthetic polymers to enhance its mechanical properties. In this study, we developed a Bio-Hybrid scaffold with non-cross linked DBPECM in its native structure coated with a layer of Polycaprolactone-Chitosan (PCL-CH) nanofibers that displayed superior mechanical properties. Surface and functional studies demonstrated integration of PCL-CH to the DBPECM with enhanced bio and hemocompatibility. This engineered Bio-Hybrid scaffold exhibited most of the physical, biochemical and functional properties of the native valve that makes it an ideal scaffold for fabrication of cardiac valve with regenerative potential.

Mutations in the pancreatic ATP sensitive K(+) channel proteins [sulfonyluea receptor 1 (SUR1) and inward rectifier K(+) channel Kir6.2 (Kir6.2), encoded by ATP-binding cassette transporter subfamily C member 8 (ABCC8) and potassium channel J11 (KCNJ11), respectively], are the most common cause of neonatal diabetes. We describe the clinical presentation and molecular characterization of Asian Indian children with neonatal diabetes mellitus and monogenic syndromes of diabetes. We sequenced KCNJ11, ABCC8 and insulin (INS) genes in 33 unrelated Indian probands with onset of diabetes below one year of age. A total of 12 mutations were identified which included ABCC8 mutations in seven, KCNJ11 mutations in three and INS mutations in two children. The Asp212Tyr mutation in ABCC8 was novel. We also detected two novel mutations (Val67Met and Leu19Arg) in children with syndromic forms of diabetes like Berardinelli Seip syndrome [1-acyl-sn-glycerol-3-phosphate acyltransferase beta (AGPAT2)] and Fanconi Bickel syndrome [solute carrier family 2A2 (SLC2A2)]. Children carrying the KCNJ11 (Cys42Arg, Arg201Cys) and ABCC8 (Val86Ala, Asp212Tyr) mutations have been successfully switched over from insulin therapy to oral sulfonylurea. Our study is the first large genetic screening study of neonatal diabetes in India.

The present study details the development of biotin tagged avidin functionalized Zinc Sulphide [ZnS] nanocrystals through a simple aqueous chemistry route at room temperature for targeted imaging applications. Surface functionalization of Manganese doped ZnS nanocrystals with L-cysteine provided functional groups that facilitated its conjugation to avidin. Further biotinylation of these particles through the strong non-covalent interaction between biotin and avidin enabled highly specific labeling of the biotin receptors on human hepatocellular carcinoma (HepG2) cells. The nanobioconjugates thus developed exhibited stable and brilliant fluorescence upon labeling the biotin receptors on cells as observed through fluorescence microscopy. Characterization studies using X-ray diffraction, dynamic light scattering as well as Fourier transform infrared spectroscopy revealed the bioconjugated particles to be appropriately functionalized and stable, with size ranging from 50 to 80 nm. Cytotoxicity of this material system evaluated using MTT, LDH leakage and apoptosis assay revealed its non-toxic nature even for high concentrations extending upto 250 microM and 48 hours of incubation. Our results confirmed that biotinylated ZnS nanocrystals offer great potential for highly specific labeling and targeted imaging of cancer cells.
