Liposomal drug delivery system as an effective treatment approach for lung cancer

Worldwide, cancer is one of the leading causes of mortality and cancer rates are set to increase at alarming rate globally. There are various types of cancer in which the leading type is the lung cancer.   In recent years lipid-based carriers, such as liposomes, have successfully encapsulated chemotherapeutic agents ameliorating some toxicity issues, while enhancing the overall therapeutic activity in cancer patients. In addition to this, nanomaterials can help to improved half-life in the body, morphology, for increased drug loading and many other ways. The survey discussed in this review will lead the anticancer therapy and cancer management which will provide the platform to the next generation.  Therefore, this critical review includes the therapeutic interventions, liposomes target delivery, active and passive drug loading. Finally, we attempt to summarize the current challenges in nanotherapeutics and provide an outlook on the future of this important field.

Tissue-dependent analysis of common and rare genetic variants for Alzheimer's disease using multi-omics data

Alzheimer’s disease (AD) is a complex neurodegenerative disease characterized by progressive memory loss and caused by a combination of genetic, environmental, and lifestyle factors. AD susceptibility is highly heritable at 58-79%, but only about one third of the AD genetic component is accounted for by common variants discovered through genome-wide association studies (GWAS). Rare variants may contribute to some of the unexplained heritability of AD and have been demonstrated to contribute to large gene expression changes across tissues, but conventional analytical approaches pose challenges because of low statistical power even for large sample sizes. Recent studies have demonstrated by expression quantitative trait locus (eQTL) analysis that changes in gene expression could play a key role in the pathogenesis of AD. However, regulation of gene expression has been shown to be context-specific (e.g., tissue and cell-types), motivating a context dependent approach to achieve more precise and statistically significant associations. To address these issues, I applied a strategy to identify new AD risk or protective rare variants by examining mutations occurring only in cases or only controls, observing that different mutations in the same gene or variable dose of a mutation may result in distinct dementias. I also evaluated the impact of rare variation on expression at the gene and gene pathway levels in blood and brain tissue, further strengthening the rare variant findings with functional evidence and finding evidence for a large immune and inflammatory component to AD. Lastly, I identified cell-type specific eQTLs in blood and brain tissue to explain underlying genetic associations of common variants in AD, and also discovered additional evidence for the role of myeloid cells in AD risk and potential novel blood and brain AD biomarkers. Collectively, these findings further explain the genetic basis of AD risk and provide insight about mechanisms leading to this disorder.2022-01-21T00:00:00

Parental responsibility: Stigmatization of parents based on child weight

Qualitative evidence, judicial decisions, and media reports suggest that parents of children with obesity experience stigma on account of their children's weights. However, to the best of my knowledge, little empirical work actually explores whether social perceivers stigmatize the parents of children with higher weight. Here, I test whether social perceivers stigmatize parents of children with 'obesity,' and ask what might drive this stigma. Specifically, I test a theory derived from an attribution explanation of weight stigma. An attribution theory explanation for stigmatizing adults who themselves have obesity argues that this stigma is driven by the negative attributions social perceivers make as to why targets have obesity (e.g., laziness). To test whether parents of children with obesity are stigmatized because the parents are attributed blame for children's weight, I conducted a highly-powered, pre-registered experiment using US participants (N = 254). I find that parents of children with obesity (versus healthy-weight) are stigmatized as parents, and this relationship between child weight and parental stigma is statistically mediated by attributions of blame toward parents for children's weights. In light of gender role breakdowns in parenting, I also tested whether this blame - and thus stigma - is greater for mothers versus fathers, but found no support for this. In addition to these focal tests, I also explore whether parents of children with obesity (a) are stigmatized in general (versus as 'parents') and (b) are attributed any negative personal characteristics stereotypically associated with obesity (e.g., greedy), as a traditional stigma-by-association account might imply, finding support for both of these propositions. In all, findings support an attribution theory of weight stigma, such that parents are blamed for their children's obesity and thus viewed as poor parents. I discuss implications and future directions for this work

A study of caesarean sections in referred cases

Background: Referral is a coordinated movement of healthcare seekers through the health system to reach a high level of care in a small and often fatal window of time. Even physiological processes like pregnancy and childbirth are not free of complications. The purpose of this study is to understand maternal and foetal outcome in caesarean sections in referred cases.Methods: A prospective study was carried out in the OBGY department of SMT.SCL HOSPITAL, NHL Municipal medical college from April 2020 to April 2021. All referred antenatal and intranatal patients to our tertiary care centre with >20 weeks of gestation who underwent caesarean section with referral note.Results: A total 64% patients were referred from community health center. 63.5% patients were referred due to lack of high-risk management services. 211 patients underwent caesarean section while 69 patients had normal vaginal delivery. Difficulty in delivery of the baby was encountered in 53% of cases due to deep engagement of the fetal head. Major cause of admission in NICU was sepsis (38.6%) followed by prematurity (23.8%).Conclusions: Cesarean section is one of the quickest and most efficient method in the delivery of the baby and thus should in considered in patients in critical situations .The millennium development goals defined by united nation includes one goal (MDG 5) towards improving maternal health which still remains a challenge. Thus, improving knowledge of women regarding good antenatal care and strengthening referral services will play a big role in this

A study of feto maternal outcome in primary caesarean section

Background: Primary caesarean section is defined as caesarean section to be performed in women who have not had previous caesarean delivery. The increase in the rates of primary caesarean section is not only due to increased caesarean section in nulligravida but also due to upward rise in caesarean section rates in parous women. Through this study we aimed to examine the frequency and the indications of primary caesarean section in nulliparous and multiparous women.Methods: A prospective study was carried out in the OBGY department of smt. SCL Hospital, NHL municipal medical college from April 2020 to April 2021. All multiparous women with previous normal vaginal delivery who underwent caesarean section this time were included in this study. Patients with previous caesarean section <28 weeks of gestation, patients who did not give consent were excluded from the study.Results: 92% were 20-30 years and are gravida 2 or 3 patients. 85% patients were booked patients. Most common indication of primary caesarean section in parous women was MSL+FD (31%). Difficulty in delivery of the baby was encountered in 45% of cases. Major cause of admission in NICU was MAS.Conclusions: Primary caesarean section has become a major driver of overall caesarean section rate. Decision making on primary caesarean section should be carefully scrutinized, introducing a diagnostic second opinion for all primary caesarean section. Primary caesarean section in both multigravida and primigravida becomes mandatory in many cases to prevent maternal and feta morbidity

A study of knowledge, awareness, and acceptance of contraception among reproductive age women at tertiary care hospital, Ahmedabad

Background: India is projected to be the most populous country according to United Nations’ report; therefore, the knowledge and awareness of contraceptive methods is of utmost important for small family norms and to increase inter-pregnancy interval, so that we can achieve optimum maternal and child outcomes. This study was conducted to assess knowledge, awareness, and acceptance of contraceptive methods among reproductive-age women during Corona pandemic.Methods: A prospective observational questionnaire-based study involving 513 women belonging to the 15-49 years of age group were interviewed with consent. This was a knowledge, attitude and practice (KAP) study regarding socio-demographic profile, knowledge, awareness, and acceptance of the contraceptive method.Results: Statistical analysis of data was done by using chi-square and percentage. Out of 513 participants, 63 participants were not using any method of contraception. Barrier method is the most commonly preferred method of contraception. There was significant association of education of women and husband, occupation with usage of contraception (p<0.001, p=0.016 and p<0.001). During corona pandemic acceptance of tubal ligation had taken a hit.Conclusions: During corona pandemic barrier method and oral contraceptive pills were preferred methods. In comparison with pre-COVID era data, tubal ligation was least preferred method. Acceptance of IUCD and Injectable contraception remained same. Higher education level and better financial status had correlation with increased awareness and acceptance of contraceptive methods

Coral bleaching due to increased sea surface temperature in Gulf of Kachchh Region, India, during June 2016

327-332The 2015-2016 E1 Niño Southern Oscillation event was one of the extreme climate events which elevated the sea surface temperature (SST) of tropical oceans, which in turn increased the level of thermal stress on corals. Coral bleaching event is mainly caused due to high positive SST anomaly, i.e., when SST exceeds its normal summer maxima. Corals in the Gulf of Kachchh region of Gujarat earlier experienced coral bleaching events during 1988, 2010 and 2014. For this study, SST was derived from NOAA OISST data set which is available daily at 0.25° global grids from 1982 to present. The climatologically warmest month for the Gulf of Kachchh region is June when the maximum monthly mean temperature is 29.31°C, as observed from NOAA OISST. The present study focuses on monitoring daily SST anomalies during summer 2016 for the Gulf of Kachchh reefs and field observations on early responses of coral bleaching from Laku Point reef, a site known for high coral diversity. It was found that in summer 2016, SST rose to 30.62 °C and recorded a maximum positive anomaly of 1.31°C in the month of June. A total of 72 days out of 122-day monitoring period showed positive SST anomaly, including 28 days of continuous positive thermal stress in June 2016.To validate coral bleaching forecast at the end of the regional warmest quarter, a field visit was carried out at Laku Point reef near Poshitra village in the southern coast of the Gulf of Kachchh. A total of 13 coral species and a sea anemone were found bleached in various proportions during the field sampling after two months of prolonged thermal stress. The field data showed an average of 3.9% bleaching of corals at colony scale. The maximum proportion of colony scale bleaching was observed in Porites lutea species

Application of Ketamine in Current Practice of Anesthesiology

Ketamine was discovered in 1964 by merging a ketone with an amine. Patients described feeling disconnected like they were floating in outer. Thus, it was characterized as a dissociative anesthetic. It is a unique drug that expresses hypnotic, analgesic, and amnesic effects. No other drug used in clinical practice produces these three important effects at the same time. Its newly found neuroprotective, anti-inflammatory, antitumor effects and low dose applications have helped to widen the clinical profile of ketamine. Ketamine as an analgesic adjunct in chronic pain patients is currently being researched. Combined use of ketamine and an opiate analgesic has been found to provide good perioperative pain control with reduction in symptoms such as nausea and vomiting, sedation, and respiratory insufficiency

Association of Rare Coding Mutations With Alzheimer Disease and Other Dementias Among Adults of European Ancestry

IMPORTANCE Some of the unexplained heritability of Alzheimer disease (AD) may be due to rare variants whose effects are not captured in genome-wide association studies because very large samples are needed to observe statistically significant associations. OBJECTIVE To identify genetic variants associated with AD risk using a nonstatistical approach. DESIGN, SETTING, AND PARTICIPANTS Genetic association study in which rare variants were identified by whole-exome sequencing in unrelated individuals of European ancestry from the Alzheimer’s Disease Sequencing Project (ADSP). Data were analyzed between March 2017 and September 2018. MAIN OUTCOMES AND MEASURES Minor alleles genome-wide and in 95 genes previously associated with AD, AD-related traits, or other dementias were tabulated and filtered for predicted functional impact and occurrence in participants with AD but not controls. Support for several findings was sought in a whole-exome sequencing data set comprising 19 affected relative pairs from Utah high-risk pedigrees and whole-genome sequencing data sets from the ADSP and Alzheimer’s Disease Neuroimaging Initiative. RESULTS Among 5617 participants with AD (3202 [57.0%] women; mean [SD] age, 76.4 [9.3] years) and 4594 controls (2719 [59.0%] women; mean [SD] age, 86.5 [4.5] years), a total of 24 variants with moderate or high functional impact from 19 genes were observed in 10 or more participants with AD but not in controls. These variants included a missense mutation (rs149307620 [p.A284T], n = 10) in NOTCH3, a gene in which coding mutations are associated with cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), that was also identified in 1 participant with AD and 1 participant with mild cognitive impairment in the whole genome sequencing data sets. Four participants with AD carried the TREM2 rs104894002 (p.Q33X) high-impact mutation that, in homozygous form, causes Nasu-Hakola disease, a rare disorder characterized by early-onset dementia and multifocal bone cysts, suggesting an intermediate inheritance model for the mutation. Compared with controls, participants with AD had a significantly higher burden of deleterious rare coding variants in dementia-associated genes (2314 vs 3354 cumulative variants, respectively; P = .006). CONCLUSIONS AND RELEVANCE Different mutations in the same gene or variable dose of a mutation may be associated with result in distinct dementias. These findings suggest that minor differences in the structure or amount of protein may be associated with in different clinical outcomes. Understanding these genotype-phenotype associations may provide further insight into the pathogenic nature of the mutations, as well as offer clues for developing new therapeutic targets
