Abstract
Chemical pollution is a global concern as contaminants are transported and reach even the remote regions of Antarctica. Seabirds serve as important sentinels of pollution due to their high trophic position and wide distribution. This study examines the influence of migration and trophic ecology on the exposure of two Antarctic seabirds, Wilson's storm petrel (Oceanites oceanicus - Ooc), and Cape petrel (Daption capense - Dca), to chemical elements and perfluoroalkyl substances (PFAS). Our methodology involved assessing the concentration of these pollutants in feather samples obtained from carcasses, offering a practical means for monitoring contamination. Trace and major element concentrations were comparable in both species, suggesting that migratory patterns have a minimal impact on exposure levels. However, Ooc had higher concentration of PFAS compared to Dca (mean, ng g-1dry weight, PFOA: Ooc:0.710, Dca:0.170; PFTrDA: Ooc:0.550, Dca:0.360, and PFTeDA: Ooc:1.01, Dca:0.190), indicating that migration to the more polluted Northern Hemisphere significantly affects PFAS exposure. Furthermore, while no strong associations were found between either trace elements or PFAS and the three stable isotopes (δ13C, δ15N, and δ34S), a negative association was observed between PFUnDA and δ15N, hinting at potential biodilution. The research concludes that the migratory patterns of these seabird species affect their PFAS exposure, underscoring the critical need for further exploration and understanding of these relationships to better inform conservation strategies.

Abstract
Reversal learning measures the ability to form flexible associations between choice outcomes with stimuli and actions that precede them. This type of learning is thought to rely on several cortical and subcortical areas, including the highly interconnected orbitofrontal cortex (OFC) and basolateral amygdala (BLA), and is often impaired in various neuropsychiatric and substance use disorders. However, the unique contributions of these regions to stimulus- and action-based reversal learning have not been systematically compared using a chemogenetic approach particularly before and after the first reversal that introduces new uncertainty. Here, we examined the roles of ventrolateral OFC (vlOFC) and BLA during reversal learning. Male and female rats were prepared with inhibitory designer receptors exclusively activated by designer drugs targeting projection neurons in these regions and tested on a series of deterministic and probabilistic reversals during which they learned about stimulus identity or side (left or right) associated with different reward probabilities. Using a counterbalanced within-subject design, we inhibited these regions prior to reversal sessions. We assessed initial and pre-/post-reversal changes in performance to measure learning and adjustments to reversals, respectively. We found that inhibition of the ventrolateral orbitofrontal cortex (vlOFC), but not BLA, eliminated adjustments to stimulus-based reversals. Inhibition of BLA, but not vlOFC, selectively impaired action-based probabilistic reversal learning, leaving deterministic reversal learning intact. vlOFC exhibited a sex-dependent role in early adjustment to action-based reversals, but not in overall learning. These results reveal dissociable roles for BLA and vlOFC in flexible learning and highlight a more crucial role for BLA in learning meaningful changes in the reward environment.

Abstract
The pandemic Covid-19 affects mainly adult causing fatal illness specially who have co-morbidities. But as days pass by with increasing surveillances it's gradually obvious that this devastating disease also affects the children as well as neonates with greater number. The aim of study was to determine the Covid-19 in neonates. So, we can give proper emphasis on neonatal Covid-19. This cross-sectional study was conducted from April 2020 to September 2020 at Dhaka Shishu (Children) Hospital in Bangladesh. Neonates with suspected Covid-19 were tested for SARS-CoV-2 by RT- PCR. Newborn who had suspected or confirmed COVID-19 mother, exposed to relatives infected with Covid-19, related with cluster outbreak or with abnormal clinical courses such as respiratory distress, not responded to conventional treatment and also abnormal chest x-ray was selected for Covid-19 test. Data regarding gestational age, birth weight, gender, positive cases and other findings were collected and analyzed. Statistics analysis was done by SPSS version 26.0. Forty three cases were Covid-19 positive. Among them 28(65.1%) cases were male and 15(34.9%) female. Term was 39(90.6%) cases and preterm 4(9.4%). Twenty nine (67.5%) cases were belonged to medicine and 14(32.6%) surgical cases. Fourteen (32.5%) cases with Covid-19 lived in Dhaka and 29(67.5%) cases in outside of Dhaka. Eleven (25.5%) cases were positive for SARS -CoV-2 by RT- PCR within 3 days, among them 5 (11.6%) cases were within 24 hours of age. Nine (20.9%) and 23(53.5%) cases were test positive at day 4-7 and 8-28 days respectively. The main symptoms at admission were respiratory difficulty (12/43, 27.9%), fever (8/43, 18.6%), convulsion (8/43, 18.6%) and reluctance to feed (7/43, 16.6%). In neonate two or more diseases coexist in same cases. Sepsis was present in 20 (46.5%) cases with COVID-19. Perinatal asphyxia was present in 10(23.3%) and pneumonia in 8 (18.6%) cases. In laboratory findings low Hb% was present in 2/43(4.7%) cases, leukopenia in 4/43(9.3%), leukocytosis in 2/43(4.7%) and thrombocytopenia in 5/43(11.6%). Elevated CRP was present in 14/29 (32.6%) cases, hypernatremia in 10/33 (30.3%), hyponatremia in 1/33(3%), increased serum creatinine in 10/18(55.6%), and prolonged PT, aPTT in 2/2(100%). Hyperglycaemia was found in 1/15(6.7%) cases and hypoglycaemia in 2/15(13.3%). No organism was found in blood C/S. In chest X-ray, one showed patchy opacities in right lower lobe, another showed bilateral ground-glass opacity and third one revealed few patchy opacities in the right perihilar region. Among 43 cases 21(48.9%) were discharged with advice, 12(27.9%) cases referred to Covid-19 designated hospital, 2(4.7%) cases LAMA (Leave against medical advice) and 8(18.6%) cases died including one surgical case. A good number (43) of Covid-19 cases were found in this study. In neonates the clinical features could not be differentiated properly between Covid-19 or associated diseases unlike children and adult. The neonate may be a source of transmission of this disease. So, we should give proper emphasis on test, tracing and management of neonatal Covid-19.

Abstract
Adolescence may be defined as the period from 10 to 19 years of age. Adolescence is a significant period of human growth and maturation when various changes occur and requirement of nutrients is increased in girls due to increase demands for growth. This prospective type of analytical cross-sectional study was carried out to observe the status of Hb concentration and serum total iron binding capacity (TIBC) levels among iron deficiency anemic adolescent girl. This study was conducted in the Department of Physiology, Mymensingh Medical College, Bangladesh from July 2019 to December 2020. For this purpose, 140 adolescent girl's age ranged from 10-19 years were selected in this study, among them, 70 healthy adolescent girls as control group (Group I) and 70 girls selected as study group (Group II) and they are iron deficiency anemic adolescent girls. Estimation of hemoglobin by cyanmethaemoglobin method and estimation of serum total iron binding capacity (TIBC) was determined by Ferrozine method using Globals iron and TIBC kit, UK. All data were expressed as mean ±SD and statistical significance of difference among the Group I and Group II were calculated by unpaired students''t' test. Hemoglobin (Hb) concentration significantly lowers in study group (Group II) in comparison with control group (Group I), Result is highly significant (p<0.001). Total iron binding capacity (TIBC) significantly higher in study group (Group II) in comparison with control group (Group I), Result is highly significant p<0.001). Immediate, long term and sustainable public health intervention would require for overcome the situation.

Abstract
The nutrient foramen is the natural opening present in the shaft of the humerus. It passes the nutrient artery to the medullary cavity. The nutrient artery is the chief artery that enters the bone through a nutrient foramen to provide nutrition for its growth. It plays an important role in healing during fracture and trauma and is also important for bone grafting. This study aimed to determine the common location, position and number of nutrient foramina of fully ossified dry human humerus. One hundred samples (right- 43 and left- 57) were selected through the purposive sampling technique for this cross-sectional descriptive study carried out in the Department of Anatomy, Mymensingh Medical College, Bangladesh from July 2021 to June 2022. Any damaged, unossified bones or fractured bones were excluded. Data were tabulated and statistically analyzed using Microsoft Excel and SPSS software. Among 43 right humeri, 37(75.51%) have single-nutrient foramen and 06(24.49%) have double-nutrient foramina. Among 57 left humeri, 53(92.98%) have single nutrient foramen, 03(5.27%) have double nutrient foramina and 01(1.75%) has triple nutrient foramina. In case of location of nutrient foramina, among 49 right nutrient foramina, 45(91.84%) were found on the anteromedial surface, 02(4.08%) were found on the anterolateral surface and 02(4.08%) were on the posterior surface of the shaft of the humerus. In case of 62 left nutrient foramina, 57(91.94%) were found on the anteromedial surface and 05(8.06%) were found on the posterior surface of the shaft of the humerus. Among 49 right nutrient foramina, 01(2.04%) was found on the upper third, 46(93.88%) on the middle third and 02(4.08%) on the lower third of the shaft of the humerus. In case of 62 left nutrient foramina, 01(1.60%) was on the upper third, 57(91.95%) were on the middle third and 04(6.45%) were on the lower third of the shaft of the humerus.

Abstract
Although naturally present in the environment, mercury (Hg) input is significantly amplified by anthropogenic activities on a global scale, leading to a growing concern about the recent increase in Hg levels observed in Antarctica. This study investigated total mercury (THg) concentrations in feathers and eggs of resident and migratory Antarctic seabirds. Stable isotope data (δ15N, δ13C, and δ34S) were employed to ascertain the key factors influencing the exposure of these species to Hg. We gathered feathers and eggs from three resident species - Adélie, Gentoo, and Chinstrap penguins, as well as five migratory species - Snowy Sheathbill, Antarctic Tern, Southern Giant Petrel, Kelp Gull, and South Polar Skua. These samples were collected from Admiralty Bay, King George Island, in the Antarctica Peninsula. For all species, THg concentrations were higher in feathers (mean ± SD: 2267 ± 2480 ng g-1 dw) than in eggs (906 ± 1461 ng g-1 dw). Species occupying higher trophic positions, such as the Southern Giant Petrel (5667 ± 1500 ng g-1 dw) and South Polar Skua (4216 ± 1101 ng. g-1 dw), exhibited higher THg levels in their feathers than those at lower positions, like Antarctic Tern (1254 ± 400 ng g-1 dw) and Chinstrap Penguin (910 ± 364 ng g-1 dw). The δ15N values, which serve as a proxy for the trophic position, significantly correlated with THg concentrations. These findings reveal that trophic position influences THg concentrations in Antarctic seabirds. Migration did not appear to significantly affect the exposure of seabirds to THg, contrary to initial expectations. This research highlights the importance of evaluating the impacts of THg contamination on the Antarctic ecosystem by considering a variety of species. This multi-species approach offers critical insights into the factors that may potentially influence the exposure of these species to contaminants.

Abstract
Cervical cancer is the fourth most common cancer in women in the world and is the second leading malignancy among Bangladeshi women. Persistent infection with high risk human papillomavirus (HPV) is an important cause of development of cervical intraepithelial neoplasia (CIN) followed by cancer. Bacterial vaginosis (BV), a common treatable vaginal infection which can disrupt the balanced vaginal ecosystem and its innate protective mechanisms against infection, can play an essential role in the acquisition and persistence of high risk human papillomavirus (HR-HPV) infection. This cross sectional study was conducted to detect the HR-HPV (HPV-16 and HPV-18) infection among bacterial vaginosis positive patient in the Department of Microbiology, Mymensingh Medical College (MMC), Bangladesh, from March 2018 to February 2019. A total of 300 endocervical swabs and high vaginal swabs were collected from the VIA (Visual inspection with acetic acid) outdoor clinic of Obstetrics and Gynaecology Department of Mymensingh Medical college Hospital. HPV DNA was tested among all 300 cases by nested PCR. Typing of HPV 16 and HPV 18 was done among HPV DNA positive cases with BV and intermediate flora by multiplex PCR. BV was diagnosed according to Nugent criteria by using the gram stained smear of high vaginal swab. A total of 57/300 (19.0%) samples were positive for HPV DNA by nested PCR. Of the total 300 cases 78(26.0%) had BV, 38(13.0%) had intermediate flora and 184(61.0%) had normal vaginal flora. HPV DNA was more positive in patients having intermediate flora 08/38 (21.05%) followed by the patients having normal vaginal flora 37/184 (20.11%) and BV 12/78 (15.38%). Among the 12 BV patients who were also HPV DNA positive (83.33%) were belong to high risk HPV (type 16 and 18) group and among them 08(66.67%) were HPV-16 and 02(16.67%) were HPV-18. But among 08 HPV DNA positive intermediate flora containing patients only 01(12.5%) were belong to HR-HPV (type 16 and no type 18 was detected).

Abstract
Nephrotic syndrome is the most common glomerular disease affecting children. Hypothyroidism is one of the most important complications which occur due to urinary loss of protein bound thyroid hormones, such as thyroxin binding globulin, transthyretin and albumin. This cross sectional study was conducted in the Department of Pediatric, Mymensingh Medical College Hospital (MMCH), Bangladesh from February 2018 to October 2019. This study was carried out to find out the thyroid profile in children with nephrotic syndrome and compared with thyroid profile of other acute illness in children. Total 122 children aged 2-12 years, further subdivided into Group A (n=61) suffering from nephrotic syndrome (1st attack, infrequent relapse) and Group B (n=61) other disease like viral fever, pneumonia, bronchiolitis, diarrhoea, UTI. Demographic details of patients and their relevant clinical details were obtained by an interviewer administered questionnaire. Blood for free T4, TSH were taken and compared between both groups. The mean FT4 values in Group A and Group B were 16.09±22.32fmol/ml and 68.22±11.65fmol/ml respectively, whereas the TSH level was significantly higher in Group A than controls (5.42±1.04 vs. 3.53±1.44). The T4 levels in nephrotic syndrome (Group A) patients were low. Analysis was done by using SPSS 22.0 version for windows software. Continuous and catagorical parameters were compared by unpaired 't' test and Chi-Square test. A p-value of 0.05 was considered significant. Hypothyroidism was found more in younger children i.e. age less than 6 years. This study concluded that children with nephrotic syndrome have a state of hypothyroidism.

Abstract
The levels of eighteen trace elements (TEs) were evaluated in association with stable isotopes (δ15N, δ34S, and δ13C) in feathers and eggs of five migratory species breeding on the Antarctic Peninsula to test the factors that influence their exposure to contaminants. The feathers of seabirds migrating to the Northern Hemisphere (South polar skua) have concentrations (mean ± SD, μg. g-1) of Li (1.71 ± 2.08) and Mg (1169.5 ± 366.8) one order of magnitude higher than southern migrants, such as Snowy sheathbill Li (0.01 ± 0.005) and Mg (499.6 ± 111.9). Feathers had significantly higher concentrations for 11 of a total of 18 metals measured compared to eggs. South polar skua have higher concentrations of all TEs in eggs compared to antarctic tern. Therefore, the present study showed that migration and trophic ecology (δ15N, δ13C, and δ34S) influence Fe, Mn, Cu, and Se concentrations in feathers of Antarctic seabirds. The concentrations of Cu, Mn, Rb, Zn, Pb, Cd, Cr are higher than previously reported, which may be due to increased local and global human activities.

Abstract
OBJECTIVES Existing socio-economic inequalities shape, in very particular and measurable ways, the differential impact that a disease has on different sections of the same society. This is particularly true of COVID-19, which has rapidly exhausted the public health system in India, and magnified the gradient of vulnerability in an underserved populace. Using publicly available data, we have aimed to deconstruct this gradient into individual variables of inequality and quantify their impact on the transmission and mortality outcomes of COVID-19 in India. STUDY DESIGN Sociodemographic analysis. METHODS We quantify doubling times and case fatality ratios for all districts in India, then correlate them to 20 variables of socio-economic vulnerability and demographic structure. Variables that exhibit persistent correlation are then analysed using multivariate beta regression models to validate their impact on COVID-19 outcomes in India. RESULTS The transmission of COVID-19 in India is enhanced by the lack of access to indoor latrines, drainage facilities, electricity, and proximate sources of drinking water. Transmission is slowed by the presence of an elderly population. Fatality rates relate negatively to an area's medical infrastructure and the presence of a college-educated populace. CONCLUSIONS An interactive matrix of social inequalities, cultural practices, and behavioural patterns determines the path of COVID-19 through a community. Specific variables exhibit patterns of persistent vulnerability; others indicate a resistance to infection and mortality. This body of evidence, when incorporated into policy design, may lead to localised, need-sensitive models of intervention, both for preventive measures and medical care.

Abstract
Hyperthyroidism is one of the major complications in CKD patients who results in a number of metabolic disorders and contributes to morbidity and mortality. The objective of the study was to investigate the prevalence and risk factors for secondary hyperparathyroidism among CKD patients as well as its correlation with different laboratory parameters. This was a cross-sectional study conducted among the admitted CKD patients of Sylhet MAG Osmani Medical College Hospital, Sylhet, Bangladesh from January 2019 to December 2019. Following recruitment, clinical parameters were extracted from the patients' medical records. Afterward, blood sample blood was collected to measure the biochemical parameters and serum parathyroid hormone levels. A binary logistic regression model was used to assess the factors associated with hyperparathyroidism. The mean±SD serum PTH in all CKD patients was 215.04±168.15 pg/ml. The overall prevalence of secondary hyperparathyroidism among CKD patients was 75.0% (32.0% in stage 3, 88.0% in stage 4 and 93.0% in stage 5 CKD). Serum PTH levels had a significant positive correlation with serum creatinine and serum phosphate levels and a significant negative correlation with serum albumin and serum calcium levels. However, only female sex was revealed as a significant risk factor in the adjusted regression model (aOR 0.26, 95% CI 0.07-0.98 for male sex compared to female sex). As the prevalence of secondary hyperparathyroidism increases in advanced stages of CKD, early detection and management of CKD are crucial to prevent metabolic disorders that could trigger the development of this complication.

Abstract
10589 Background: Germline and somatic genetic testing are established tools for the management of cancer patients. Somatic testing is primarily used to inform therapy and germline testing is used to diagnose hereditary cancer predisposition syndromes. While somatic testing can detect germline variants, the interpretation and reporting algorithms are optimized to predict therapeutic efficacy. As a result, germline variants may be missed or only interpreted in context of their potential to act as a therapeutic target. We retrospectively reviewed a series of patients who received both germline and somatic testing to examine the opportunities for concurrent germline testing to improve somatic reporting. Methods: Our study reviewed data from 43 patients with solid cancer diagnoses who were otherwise unselected and underwent testing with a 435-gene somatic genetic test and an 83-gene germline test. The most frequent cancers were pancreatic (18), ovarian (8), and prostate (7). Results: Out of the 43 patients, 7 (16%) harbored a pathogenic or likely pathogenic germline variant (PGV) in a cancer susceptibility gene. PGVs were identified in MLH1, MSH6, CHEK2, PALB2, CDKN2A, NBN, and MUTYH. Notably, 3 of these genes ( CHEK2, PALB2, MUTYH) were not considered therapeutic targets, and therefore were only included as ancillary findings near the end of the preliminary somatic test reports (generated prior to integration of germline test results). In addition, 40 of 43 (93%) patients had at least one variant detected by somatic testing in at least one of the germline panel genes (mean number variant genes = 4.1, maximum = 10); all of these variants were within the reportable range of the germline assay, and therefore germline test results were able to resolve their germline versus somatic origins. The genes that most frequently had somatic variants identified were TP53 (79% of patients), CDKN2A (37%), SMAD4 (30%), and FLCN (21%). Conclusions: Due to the size of commonly ordered somatic gene panels, there is a high probability of detecting variants in hereditary cancer predisposition genes (> 90% of patients in this study) that can provide either therapy or cancer risk information or both. Given that a significant proportion (16% in this study) of cancer patients harbor PGVs (which can further inform treatment, disease surveillance, preventive measures, and risk assessment for family members), it is crucial to resolve the somatic versus germline origin of these variants. Since interpretation and reporting algorithms for somatic testing are optimized for therapy prediction, and variables such as specimen tumor purity, tumor ploidy, and variant allele fraction render estimates of variant origin unreliable for diagnostic purposes, it is important to take advantage of germline testing concurrently in patients receiving somatic testing to glean this critical information.

Abstract
The industries and metropolitan wastes produced by anthropogenic activities are of great concern for nature as it causes soil contamination and deteriorate the environment. Plastic utilization is rapidly enhancing globally with passing days that last for a more extended period in the environment due to slow decomposition and natural degradation. Excessive use of polymer has risked the life of both marine, freshwater and terrestrial organisms. Lack of proper waste management and inappropriate disposal leads to environmental threats. Bioremediation processes involve microbes such as fungi, bacteria, etc. which contribute a crucial role in the breakdown of plastics. Extremophiles secrete extremozymes that are functionally active in extreme conditions and are highly crucial for polymer disaggregation in those conditions.

Abstract
Contaminant levels are lower in Antarctica than elsewhere in the world because of its low anthropogenic activities. However, the northern region of the Antarctic Peninsula, is close to South America and experiences the greatest anthropogenic pressure in Antarctica. Here, we investigated, in two Antarctic Peninsula islands, intra and interspecific factors that influence the concentrations of 17 trace elements (TEs) in blood and feathers of three penguin species breeding sympatrically in relation to their trophic ecology assessed via a stable isotopic approach (C, N and S). Geographical location, foraging zone (δ13C and δ34S) and diet influences the interspecific difference, and sex and maturity stage diet influence the intraspecific difference of Pygoscelis penguins. Penguins from Livingston showed higher values (mean, ng. g-1, dry weight - dw) of Zn (103), Mn (0.3), and Fe (95) than those from King George Island (Zn: 80, Mn: 1.9, and Fe: 11). Gender-related differences were observed, as males showed significantly higher values (mean, ng. g-1, dw) of Rb (3.4) and δ15N in blood of gentoo, and Ca (1344) in Adélie feathers. Chicks of gentoo and Adélie presented higher Zn, Mg, Ca, and Sr and lower 13C values in blood than adults. The highest concentrations (mean, ng. g-1, dw) of Cd (0.2) and Cu (26), and the lowest δ15N values were found in chinstrap. Geographical, intraspecific (i.e., ontogenetic and gender-related) and interspecific differences in feeding seemed to have influenced TE and stable isotope values in these animals. The TE bioaccumulation by penguins may have also been influenced by natural enrichment in environmental levels of these elements, which seems to be the case for Fe, Zn, and Mn. However, the high level of some of the TEs (Mn, Cd, and Cr) may reflect the increase of local and global human activities.

Abstract
This introductory chapter to our Environment International VSI does not need an abstract and therefore we just include our recommendations below in order to proceed with the resubmission. Future work should examine waterbirds as food web sentinels of multiple stressors as well as Baltic Sea food web dynamics of hazardous substances and how climate change may modify it. Also, future work should aim at further extending the new frameworks developed within BALTHEALTH for energy and contaminant transfer at the population level (Desforges et al., 2018, Cervin et al., 2020/this issue Silva et al., 2020/this issue) and their long term effects on Baltic Sea top predators, such as harbour porpoises, grey seals ringed seals, and white-tailed eagles. Likewise, the risk evaluation conducted for PCB in connection with mercury on Arctic wildlife (Dietz et al., 2019, not a BONUS BALTHEALTH product) could be planned for Baltic Sea molluscs, fish, bird and marine mammals in the future. Finally, future efforts could include stressors not covered by the BONUS BALTHEALTH project, such as food web fluxes, overexploitation, bycatches, eutrophication and underwater noise.

Abstract
Cell-surface sphingomyelin (SM) inhibits binary and ternary complex activity of blood coagulation by an unknown mechanism. Here we show the OH functionality of SM contributes in forming the close assembly through intermolecular H-bond and through Ca2+ chelation, which restricts the protein–lipid/protein–protein interactions and thus inhibits the coagulation procedure. Cell-surface sphingomyelin (SM) inhibits binary and ternary complex activity of blood coagulation.![]()

Abstract
The National Blood Transfusion Services under the aegis of the ministry of health and family welfare, India has recently issued guidelines regarding the blood donor selection criteria and the processing of blood. Care has been taken to make the blood transfusions safer. However, COVID-19 has disrupted the organization of the voluntary blood donation drives, whole blood donations [WBD] and restricted the donors' movement to the blood transfusion centres all across the world. While sickness and the need for transfusions are very much in place, the gap of demand against blood collection has widened. Additionally, with the monsoon season at hand, and the categorical challenges of a dengue outbreak, the subsequent need for blood components especially the platelet concentrates is going to rise. Some of the criteria laid for deferring a blood donor from his or her WBD need a categorical revision, considering these unprecedented times. We, therefore, critically analyzed the blood donor selection criteria and hereby, suggest an updating regarding the pre-donation haemoglobin, sexually transmitted diseases, lactation, pregnancy and many such subheadings. We also suggest collecting smaller blood volumes in the blood bags for the optimal benefit of the recipients both for now and also as a measure of pandemic preparedness for future use.

BACKGROUND AND PURPOSE Patients with chronic focal epilepsy may have atrophy of brain structures important for the generation and maintenance of seizures. However, little research has been conducted in patients with newly diagnosed focal epilepsy (NDfE), despite it being a crucial point in time for understanding the underlying biology of the disorder. We aimed to determine whether patients with NDfE show evidence of volumetric abnormalities of subcortical structures. METHODS Eighty-two patients with NDfE and 40 healthy controls underwent magnetic resonance imaging scanning using a standard clinical protocol. Volume estimation of the left and right hippocampus, thalamus, caudate nucleus, putamen and cerebral hemisphere was performed for all participants and normalised to whole brain volume. Volumes lower than two standard deviations below the control mean were considered abnormal. Volumes were analysed with respect to patient clinical characteristics, including treatment outcome 12 months after diagnosis. RESULTS Volume of the left hippocampus (p(FDR-corr) = 0.04) and left (p(FDR-corr) = 0.002) and right (p(FDR-corr) = 0.04) thalamus was significantly smaller in patients relative to controls. Relative to the normal volume limits in controls, 11% patients had left hippocampal atrophy, 17% had left thalamic atrophy and 9% had right thalamic atrophy. We did not find evidence of a relationship between volumes and future seizure control or with other clinical characteristics of epilepsy. CONCLUSIONS Volumetric abnormalities of structures known to be important for the generation and maintenance of focal seizures are established at the time of epilepsy diagnosis and are not necessarily a result of the chronicity of the disorder.

Abstract
IMPORTANCE Both germline genetic testing and tumor DNA sequencing are increasingly used in cancer care. The indications for testing and utility of these 2 tests differ, and guidelines recommend that germline analysis follow tumor sequencing in certain patients to determine whether particular variants are of somatic or germline origin. Broad clinical experience with such follow-up testing has not yet been thoroughly described. OBJECTIVE To examine the yield and utility of germline testing following tumor DNA sequencing in a large, diverse patient population. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study examined germline testing through a laboratory supporting multiple academic and community clinics. Participants included 2023 patients with cancer who received germline testing and previously underwent tumor DNA sequencing. These patients received germline testing between January 5, 2015, and January 31, 2020, although most (81% of patients) received testing between January 2, 2018, and January 31, 2020. MAIN OUTCOMES AND MEASURES The prevalence of pathogenic germline variants (PGVs) was calculated by gene, cancer type, and age at diagnosis. Potential actionability of these findings was determined based on current management guidelines, precision therapy labels, and clinical trial eligibility criteria. Patient records were reviewed to determine whether germline follow-up testing would have been recommended by current guidelines. RESULTS Among 2023 eligible patients, 1085 were female (53.6%), and the median age at cancer diagnosis was 56 (range, 0-92) years. Pathogenic germline variants were detected in 617 patients (30.5%; 95% CI, 28.5%-32.6%) and were prevalent across patient ages (1-85 years) and cancer types, including cancers known to be strongly associated with germline variance (eg, breast, colorectal) as well as others (eg, renal, lung, and bladder). Many patients (78%-82%) with PGVs met criteria for germline follow-up testing, and 8.1% of PGVs were missed by tumor sequencing. Among those with germline-positive findings, 69 patients (11.2%) had PGVs identified only after presenting with a second primary cancer that possibly could have been detected earlier or prevented given current gene-specific surveillance and risk-reduction recommendations. CONCLUSIONS AND RELEVANCE The findings of this study suggest that germline analysis following tumor sequencing often produces findings that may impact patient care by influencing systemic therapy choices, surgical decisions, additional cancer screening, and genetic counseling in families. Current guidelines and tumor testing approaches appear to capture many, but not all, of these germline findings, reinforcing the utility of both expanded germline follow-up testing as well as germline analysis independent of tumor sequencing in appropriate patients.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
Objectives Socio-economic inequalities may affect coronavirus disease 2019 (COVID-19) incidence. The goal of the research was to explore the association between deprivation of socio-economic status (SES) and spatial patterns of COVID-19 incidence in Chennai megacity for unfolding the disease epidemiology. Study design This is an ecological (or contextual) study for electoral wards (subcities) of Chennai megacity. Methods Using data of confirmed COVID-19 cases from May 15, 2020, to May 21, 2020, for 155 electoral wards obtained from the official website of the Chennai Municipal Corporation, we examined the incidence of COVID-19 using two count regression models, namely, Poisson regression (PR) and negative binomial regression (NBR). As explanatory factors, we considered area deprivation that represented the deprivation of SES. An index of multiple deprivations (IMD) was developed to measure the area deprivation using an advanced local statistic, geographically weighted principal component analysis. Based on the availability of appropriately scaled data, five domains (i.e., poor housing condition, low asset possession, poor availability of WaSH services, lack of household amenities and services, and gender disparity) were selected as components of the IMD in this study. Results The hot spot analysis revealed that area deprivation was significantly associated with higher incidences of COVID-19 in Chennai megacity. The high variations (adjusted R2: 72.2%) with the lower Bayesian Information Criteria (BIC) (124.34) and Akaike's Information Criteria (AIC) (112.12) for NBR compared with PR suggests that the NBR model better explains the relationship between area deprivation and COVID-19 incidences in Chennai megacity. NBR with two-sided tests and P <0.05 were considered statistically significant. The outcome of the PR and NBR models suggests that when all other variables were constant, according to NBR, the relative risk (RR) of COVID-19 incidences was 2.19 for the wards with high housing deprivation or, in other words, the wards with high housing deprivation having 119% higher probability (RR = e0.786 = 2.19, 95% confidence interval [CI] = 1.98 to 2.40), compared with areas with low deprivation. Similarly, in the wards with poor availability of WaSH services, chances of having COVID-19 incidence was 90% higher than in the wards with good WaSH services (RR = e0.642 = 1.90, 95% CI = 1.79 to 2.00). Spatial risks of COVID-19 were predominantly concentrated in the wards with higher levels of area deprivation, which were mostly located in the northeastern parts of Chennai megacity. Conclusions We formulated an area-based IMD, which was substantially related to COVID-19 incidences in Chennai megacity. This study highlights that the risks of COVID-19 tend to be higher in areas with low SES and that the northeastern part of Chennai megacity is predominantly high-risk areas. Our results can guide measures of COVID-19 control and prevention by considering spatial risks and area deprivation. COVID-19 cases was modelled using Poisson regression and negative binomial regression. An IMD was devised using geographically weighted principal component analysis. Area deprivation in Chennai has both positive and inverse associations with the COVID-19.

Abstract
e17615 Background: Increasing evidence suggests criteria for germline testing of patients with prostate cancer (PCa) may miss potentially actionable pathogenic variants. A sponsored testing program with significantly broader criteria was initiated to increase access. Methods: We analyzed de-identified data from 2,252 men with PCa who received at least an 84 gene panel. Inclusion criteria were clinical stage ≥T2 and willingness of the patient and physician to participate. Positive results were categorized as: pathogenic (P), likely pathogenic (LP), or increased risk alleles (IRAs). Results: Clinical stage was available in 1825 men (81%): 541 (30%) were stage II, 228 (12%) stage III, and 1,056 (58%) stage IV (Demographics Table). Among all men, 297 (13%) had positive results, including 286 P/LP variants in 38 genes and 31 IRAs in APC and HOXB13. There was no statistically significant association between stage and positive rate. Of men with positive variants, only 30% reported a family history of prostate, breast, ovarian or pancreatic cancer. The most common positive variants were in BRCA1 (9) , BRCA2 (43) , PALB2 (11) , ATM (36) , CHEK2 (58) , HOXB13 (20) , and mismatch repair genes (8). With respect to ethnicity, the highest positive rate was observed in Ashkenazi Jews (23.8%) and the lowest in African Americans (5.4%). Overall, 190 (70%) of men had P/LP variants conferring eligibility for gene-specific precision therapies or clinical trials based on variants in homologous repair (182), or mismatch repair (8) genes. Conclusions: In a broad PCa patient population, we found overall germline positive rate of 13%, with no statistical difference in this rate with respect to stage. Overall, these data suggest that broader testing criteria and more access to testing could lead to better informed care for many additional patients and their families. [Table: see text]

Abstract
1092 Background: Germline genetic testing is recommended for breast cancer patients with specific presentations or family histories. Separately, tumor DNA sequencing is increasingly used to inform therapy, most often in patients with advanced disease. Recent NCCN and ESMO guidelines recommend germline testing following somatic testing, under specific circumstances and for specific genes. We examined the utility of germline findings in patients referred for both test modalities. Methods: We reviewed somatic and germline mutations in a consecutive series of patients who: (a) had a current or previous breast cancer diagnosis, (b) were referred for germline testing, and (c) previously received tumor sequencing. Diverse reasons for germline testing included: a tumor finding of potential germline origin, treatment or surgical planning, personal or family history, and patient concern. Results: 227 patients met study criteria of whom 88 (39%) harbored a pathogenic germline variant (PGV) in a high or moderate risk cancer predisposition gene. Mutations in certain genes were most likely to be of germline origin, and most PGVs were potentially actionable (Table). 13% of PGVs were not reported by tumor tests as either germline or somatic findings, usually a result of tumor test limitations. Of note, 27 of the patients with PGVs (31%) had these variants uncovered only after presenting with a second, possibly preventable, malignancy. Conclusions: Germline testing following tumor sequencing often yielded findings that may impact care. Indeed, the 39% PGV rate we observed suggests that such testing may be underutilized. We observed actionable PGVs missed by somatic tests, PGVs uncovered in patients’ second malignancies, and PGVs not within germline reflex testing criteria. These results reinforce the utility of germline testing separate from somatic testing in appropriate patients. [Table: see text]

Abstract
e16783 Background: PARP inhibitor (PARPi) treatment was recently approved for pancreatic cancer (PaCa) patients with germline mutations in 2 DNA damage repair (DDR) genes. Despite criteria recommending germline multigene panel testing for all PaCa patients, barriers to testing remain, including among underserved populations, which limit access to precision therapies. We initiated a sponsored testing program that increases access to germline genetic testing for PaCa in two ways: 1) offering a comprehensive multigene panel, and 2) removing the barrier of cost. Here we present initial results from this program, including the diagnostic yield in patients across stages of PaCa and clinical utility of the findings. Methods: We retrospectively analyzed de-identified data from 966 PaCa patients tested on an 84 gene panel as part of the program to date. The only inclusion criterion was a willingness to participate in the sponsored program by the patient and the provider who ordered the testing. Data included likely pathogenic (LP) and pathogenic (P) mutations, disease stage and ethnicity. Results: In total, 166 (17%) patients were positive for P/LP germline mutations in 30 genes. Mutation rate by ethnicity was: Caucasian 17%, African American 12%, Hispanic 16%, Ashkenazi Jewish 20%, Asian 3%. Only 25% of patients with P/LP variants reported a family history of cancer. There was no statistical difference in mutation rates by stage (p = 0.11) [Table]. In positive patients, 83 (78%) had mutations conferring potential eligibility for DDR gene-specific precision therapies or clinical treatment trials. 28 (26%) were potentially eligible for olaparib due to BRCA1/2 mutations, 8 (7%) were potentially eligible for pembrolizumab, and 47 (44%) for PARPi clinical trials. Conclusions: This study found 8.5% of all PaCa patients tested are potentially eligible for germline-based precision therapies and/or clinical treatment trials. Of mutation positive patients, 75% did not report a family history of cancer. The positive rate was not statistically different between patients with stage I and stage IV PaCa, underscoring the recommendation to test all patients with PaCa. This program had a 1.5% increased relative uptake among African American patients compared to a standard insurance reimbursement delivery model. These data suggest reducing barriers improves PaCa patient access to genetic information that enables precision therapy. [Table: see text]

Abstract
1591 Background: NCCN guidelines recommend germline testing for patients with localized or advanced prostate cancer meeting family history or clinical/pathologic criteria. However, the guidelines for somatic molecular analysis generally consider advanced disease only, primarily to inform therapy. As the analytical and clinical specifications of both testing modalities differ accordingly, we examined the results of germline testing following prior somatic testing. Methods: We reviewed somatic and germline variants in an otherwise unselected consecutive series of patients who: (a) had a current or previous diagnosis of prostate cancer; (b) had undergone tumor sequencing; and (c) were referred for germline testing. Indications for germline testing included: potential germline origin of somatic test result, treatment or surgical planning, personal or family history, and patient concern. Results: 208 patients met study criteria of whom 81 (39%) harbored a pathogenic germline variant (PGV) in a cancer predisposition gene. Certain genes were more likely to harbor germline variants, and 98% (81) of PGVs were potentially actionable (Table). 9.6% of PGVs were not reported by somatic testing, reflecting analytical limitations of the somatic testing. Of note, 11 patients (14%) had PGVs identified after diagnosis of a subsequent primary malignancy. Conclusions: The high PGV rate of 39% was unexpected, given reported rates of 11.8% in patients with metastatic prostate cancer and 6% in high-risk localized disease (NCCN)--even considering potential clinician ascertainment bias. This finding, the potential clinical utility of 98% of PGVs identified, the significant proportion unreported by somatic testing, and the fraction of patients diagnosed with a PGV after a subsequent malignancy all suggest that germline testing is an underutilized tool in the care of prostate cancer patients and their families.

Abstract
e16089 Background: Practice guidelines support genomic and biomarker testing of colorectal cancer (CRC) to inform treatment options in advanced disease and to screen for MMR deficiency/MSI/Lynch syndrome. As yet, guidelines for follow-up germline testing are not well established. In 2019 ESMO recommended reflex germline testing when pathogenic variants (PV) were found in any of 27 cancer susceptibility genes (CSG) in tumor samples (PMID 31050713). The CSGs were chosen because PV in these genes were clinically actionable and had “germline conversion rates” (GCR) of > 10% (proportion of tumor-detected PV that were germline). We examined the utility of germline testing in a cohort of CRC patients who had prior tumor sequencing. Methods: We reviewed somatic & germline PV in an unselected consecutive series of CRC patients who were referred for germline testing and had prior tumor testing. We determined the GCR for genes with pathogenic germline variants (PGV) and compared our results to ESMO data. Results: 66 of 238 (27%) patients harbored PGV. 15% of PGV were not reported in the tumor assay. High GCR for BRCA1/2 (30%), MMR genes (40%), PALB2 (57%), and BRIP1 (67%) were in keeping with ESMO. Low GCR for APC (1.4%) and TP53 (3%) were similar to ESMO, and reflective of high somatic mutation rates in these genes. We noted high GCR for CHEK2 (75%) and ATM (24%), two genes not included in ESMO guidelines due to their intermediate penetrance. Conclusions: ESMO guidelines provide a key starting point for when reflex germline testing should be pursued after tumor testing. In our study 27% (65/238) of patients had PGV that conferred potential eligibility for targeted therapy or clinical trials. For CRC, finding PV in MMR genes, BRCA1/2, and other relevant CSGs should prompt follow-up germline testing. In cases with APC PV in tumor, ESMO recommended reflex germline testing only in patients < 30 yo, where the GCR was > 10%. Our study suggests that reflex germline testing after tumor sequencing yields clinically actionable results. [Table: see text]

Abstract
Introduction: Immune checkpoint inhibitors (ICI) represent a major component of systemic therapy in advanced malignancy. Studies have reported unique spectrum of toxicity profile of ICI as compared to systemic chemotherapy. Aim of this study is to evaluate toxicities of ICI in our population and to compare this with published data. Material and Methods: We retrospectively reviewed medical records of patients treated with ICI at Dubai hospital and American hospital Dubai from November 2015 to April 2019. After patient identification from hospitals cancer registry, data regarding patients’ demographics, cancer type, type of ICI, adverse events, and duration of treatment were collected. Results: Forty-Five patients were identified with median age of 60 (27-80) years. 27 (60%) patients were male and 18 (40%) were female. Underlying diagnosis was lung cancer (n=25), renal cell cancer (n=6), melanoma (n=5), bladder cancer (n=3), Hodgkins lymphoma (n=3) and other malignancies (n=3). Majority of patients received Nivolumab (n=20, 44%) followed by Pembrolizumab (n=19, 42%), Atezolizumab (n=4, 9%) and Durvalumab (n=2, 5%) respectively. Thyroid dysfunction was the most common side effect observed in 17 (38%) patients including hypothyroidism (n=12, 27%) and hyperthyroidism (n=5, 11%). 53 % patients treated with Nivolumab developed thyroid dysfunction as compared to Pembrolizumab (22%). 7 patients (16%) had elevated liver enzymes. Grade II and III hepatotoxicity was noted in 1 patient (2.2 %) each. One patient (2.2 %) developed grade II skin toxicity. One patient (2.2 %) developed grade III colitis. Grade II, III and IV pneumonitis was observed in 2 (4.4 %), 1 (2.2%) and 1 (2.2%) patient respectively. Immune mediated adverse events were managed according to standard guidelines and 2 patients (4.4 %) had treatment discontinuation due to grade IV Pneumonitis and grade III Colitis. Conclusion: Our study reports relatively higher incidence of thyroid adverse events in patients treated with ICI. The incidence of grade III-IV immune related toxicity remains low. Overall treatment with ICI was tolerated reasonably well and toxicity was manageable.

Abstract
Background Calcium channel blockers are considered the first line drug over renin-angiotensinaldosterone system inhibitor in black population and with renin-angiotensinaldosterone system inhibitor in non-black population with Hypertension. Amlodipine has longer biological half life and lower potential to stimulate SNS. But, is associated with reflex tachycardia and pedal oedema. Cilnidipine has potent inhibitory both on voltage gated L-type and N-type calcium channels with better anti-proteinuric effect and good tolerability. Hence, our study compared the efficacy, safety and compliance of cilnidipine over amlodipine in Stage 1 hypertensive subjects. Objective To find out antihypertensive and renoprotective effect of cilnidipine. Method The study was open-label, single centre, prospective, parallel design, randomized controlled was done in Outdoor Patient Department (OPD) of Medicine and Department of Pharmacology in Burdwan Medical College and Hospital (BMCH). Patients with stage 1 HTN received cilnidipine while the other group received amlodipine. There were 4 follow-up visits for each participant consisting of baseline, 1 week, 6 weeks and after 12 weeks. Clinical parameters including pulse rate, blood pressure and ankle oedema noted also laboratory investigations were done. Safety parameters with adverse events and compliance by traditional pill count method. Result Blood pressure was effectively decreased by both amlodipine and cilnidipine. Cilnidipine significantly decreased Pulse Rate while amlodipine increased it and the difference in Pulse Rate comparing both the groups was statistically significant. None of the ADRs were statistically significant except pedal oedema. Pedal oedema was noted only in amlodipine arm and was statistically significant. Compliance to both the drugs was excellent. Total cost of therapy was higher with cilnidipine. Conclusion Though amlodipine is preferred drug, cilnidipine should be a better alternative when we consider subjects with sympathetic over activity, proteinuria or pedal oedema.

Abstract
The PHENIX collaboration presents first measurements of low-momentum (0.4<p_{T}<3 GeV/c) direct-photon yields from Au+Au collisions at sqrt[s_{NN}]=39 and 62.4 GeV. For both beam energies the direct-photon yields are substantially enhanced with respect to expectations from prompt processes, similar to the yields observed in Au+Au collisions at sqrt[s_{NN}]=200. Analyzing the photon yield as a function of the experimental observable dN_{ch}/dη reveals that the low-momentum (>1 GeV/c) direct-photon yield dN_{γ}^{dir}/dη is a smooth function of dN_{ch}/dη and can be well described as proportional to (dN_{ch}/dη)^{α} with α≈1.25. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different A+A collision systems. At a given beam energy, the scaling also holds for high p_{T} (>5 GeV/c), but when results from different collision energies are compared, an additional sqrt[s_{NN}]-dependent multiplicative factor is needed to describe the integrated-direct-photon yield.

Abstract
AIM Chronic radiation proctitis (CRP) develops in 5-15% of patients after pelvic radiation therapy, with rectal bleeding being the main symptom. Reports suggest that argon plasma coagulation (APC) can be an effective therapy for CRP following radiotherapy for prostate cancer, but there is less information about how useful it is after radiotherapy for gynaecological malignancy. The aim of this work therefore was to study the efficacy of APC for CRP after radiotherapy for gynaecological malignancy. METHOD This was a prospective study of consecutive patients with CRP following radiotherapy for gynaecological malignancy at IPGME&R, SDLD, Kolkata, India; symptoms included rectal bleeding grade (RBG) ≥ 2. APC was performed at monthly intervals to a maximum of four treatment sessions. Severity of disease at baseline was graded (endoscopically) by the total colonoscopic severity score (TCSS) and treatment response was assessed by reduction in RBG from ≥ 2 to ≤ 1 measured at > 6 months after cessation of APC. RESULTS Seventy patients [90% with cervical cancer, 10% with endometrial cancer; mean age 51.93 ± 9.15 years; median RBG 3 (range 2-4)] received APC. Seven patients died due to underlying malignancy and seven patients were lost to follow-up. Fifty-six (85.7%) patients responded to therapy after a median of 2 (range 1-4) treatment sessions. Multivariate analysis demonstrated that a lower haemoglobin at the start of treatment predicted failure of therapy (P < 0.05). CONCLUSION APC is an effective management option for CRP in female patients with gynaecological malignancy. However, the more anaemic the patient the less likely it is to be successful.

Abstract
Application of HIV-1 protease inhibitors (as an anti-HIV regimen) may serve as an attractive strategy for anti-HIV drug development. Several investigations suggest that there is a crucial need to develop a novel protease inhibitor with higher potency and reduced toxicity. Monte Carlo optimized QSAR study was performed on 200 hydroxyethylamine derivatives with antiprotease activity. Twenty-one QSAR models with good statistical qualities were developed from three different splits with various combinations of SMILES and GRAPH based descriptors. The best models from different splits were selected on the basis of statistically validated characteristics of the test set and have the following statistical parameters: r2 = 0.806, Q2 = 0.788 (split 1); r2 = 0.842, Q2 = 0.826 (split 2); r2 = 0.774, Q2 = 0.755 (split 3). The structural attributes obtained from the best models were analysed to understand the structural requirements of the selected series for HIV-1 protease inhibitory activity. On the basis of obtained structural attributes, 11 new compounds were designed, out of which five compounds were found to have better activity than the best active compound in the series.

Abstract
Gadolinium-based contrast agents have greatly expanded the capability of magnetic resonance imaging and have been used extensively in neuroradiology over the past 30 years. When initially developed they were thought to be relatively harmless; it was later discovered they are associated with nephrogenic systemic fibrosis and should be used with caution in certain patient groups, especially those with renal failure. Lately it has been found that the use of these contrast agents may result in deposition of gadolinium in the brain even in patients with an intact blood-brain barrier. While this has not been shown to be associated with any clinical effects, a precautionary approach has been advised by the regulatory authorities. Here we review the development of the gadolinium contrast agents, their use and the advice related to this new information.

Abstract
The effect of addition of curcumin on the adsorption and transport characteristics of a cationic dye, LDS+, across negatively charged bilayers composed of POPG and DPPG lipids were investigated by the interface selective second harmonic (SH) spectroscopic technique. Curcumin induced changes in the SH electric field signal of the LDS+ ions (E2ω (LDS+)) were observed to depend critically on the bilayer acyl chain saturation/unsaturation ratio (S/U). Following earlier works, the increase in the E2ω (LDS+) signal is attributed to the release of the Na+ counterions present in the head group region of the bilayer by curcumin and the decay of the E2ω (LDS+) signal is attributed to the bilayer intercalated state of curcumin. While the changes observed in the E2ω (LDS+) signal in the presence of POPG liposomes were consistent with our earlier study ( Varshney, G. K. et al. Langmuir , 2016 , 32 , 10415 - 10421 ), they were significantly different for DPPG liposomes, following curcumin addition. While the increase in the E2ω (LDS+) signal in the presence of POPG liposomes, is marginal (∼10-20%) and instantaneous (<1 s) followed by a rapid decay (completed within ∼100 s), in the presence of DPPG liposomes it was observed to increase slowly and at saturation shows a substantial increase (100-200%), following curcumin addition. When liposomes consisting of a mixture of POPG and DPPG lipids are used, curcumin induced kinetic characteristics of the E2ω (LDS+) signal showed a mixture of the individual kinetic characteristics observed for the unsaturated (POPG) and saturated (DPPG) liposomes. The observed kinetic trends of the E2ω (LDS+) signal following curcumin addition are explained on the basis of the relative strength of the Na+-POPG and Na+-DPPG interaction. Higher ordering of the lipid acyl chain region in DPPG liposome makes the Na+-DPPG interaction much stronger than the Na+-POPG interaction. Further, it is proposed that, in POPG-DPPG liposomes, individual domains of POPG and DPPG lipids exist at low temperature as suggested by the observed temperature dependent kinetic characteristics of the E2ω (LDS+) signal following curcumin addition. These domains are dependent on the S/U ratio and phase state of the bilayer. The gel phase was observed to be more conducive for individual domain formation. Results presented in this work not only support the notion that biological activity of curcumin is associated with its bilayer altering properties, but more interestingly it provides a qualitative insight about how bilayer phase separation can be achieved by modulating the hydrophobic interactions between the lipid acyl chains.

Abstract
BACKGROUND Most people with stroke in India have no access to organised rehabilitation services. The effectiveness of training family members to provide stroke rehabilitation is uncertain. Our primary objective was to determine whether family-led stroke rehabilitation, initiated in hospital and continued at home, would be superior to usual care in a low-resource setting. METHODS The Family-led Rehabilitation after Stroke in India (ATTEND) trial was a prospectively randomised open trial with blinded endpoint done across 14 hospitals in India. Patients aged 18 years or older who had had a stroke within the past month, had residual disability and reasonable expectation of survival, and who had an informal family-nominated caregiver were randomly assigned to intervention or usual care by site coordinators using a secure web-based system with minimisation by site and stroke severity. The family members of participants in the intervention group received additional structured rehabilitation training-including information provision, joint goal setting, carer training, and task-specific training-that was started in hospital and continued at home for up to 2 months. The primary outcome was death or dependency at 6 months, defined by scores 3-6 on the modified Rankin scale (range, 0 [no symptoms] to 6 [death]) as assessed by masked observers. Analyses were by intention to treat. This trial is registered with Clinical Trials Registry-India (CTRI/2013/04/003557), Australian New Zealand Clinical Trials Registry (ACTRN12613000078752), and Universal Trial Number (U1111-1138-6707). FINDINGS Between Jan 13, 2014, and Feb 12, 2016, 1250 patients were randomly assigned to intervention (n=623) or control (n=627) groups. 33 patients were lost to follow-up (14 intervention, 19 control) and five patients withdrew (two intervention, three control). At 6 months, 285 (47%) of 607 patients in the intervention group and 287 (47%) of 605 controls were dead or dependent (odds ratio 0·98, 95% CI 0·78-1·23, p=0·87). 72 (12%) patients in the intervention group and 86 (14%) in the control group died (p=0·27), and we observed no difference in rehospitalisation (89 [14%]patients in the intervention group vs 82 [13%] in the control group; p=0·56). We also found no difference in total non-fatal events (112 events in 82 [13%] intervention patients vs 110 events in 79 [13%] control patients; p=0·80). INTERPRETATION Although task shifting is an attractive solution for health-care sustainability, our results do not support investment in new stroke rehabilitation services that shift tasks to family caregivers, unless new evidence emerges. A future avenue of research should be to investigate the effects of task shifting to health-care assistants or team-based community care.

Abstract
Six male Tharparkar cattle aged 2-3 years were selected for the study. The animals were acclimatized in the psychrometric chamber at thermoneutral zone (TNZ) for 15 days and then exposed to 42 °C temperature up to 23 days followed by 12 days of recovery period. Physiological responses were estimated, and peripheral blood mononuclear cells (PBMCs) were isolated at TNZ on day 1, day 5, and day 12; after 6 h of heat stress exposure on day 16 to day 20, day 25, day 30, day 32, day 34, day 36, and day 38; and a recovery period on day 45 and day 50. The PBMCs were cultured to study the effect of thermal challenge on HSP70 messenger RNA (mRNA) expression pattern at different temperature-time combinations. The mRNA and protein expression of HSP70 in PBMCs along with serum extracellular HSP70 (eHSP70) was increased (P < 0.05) and showed two peaks on day 17 and day 32 (2nd and 17th days of thermal challenge, respectively). The HSP70 mRNA expression was increased (P < 0.05) in a temperature- and time-dependent manner in heat stress challenge treatment as compared to control in cultured PBMCs. HSP70 expression was found to be higher (P < 0.05) after 10 days of heat exposure (corresponds to chronic heat stress) as compared to the first 5 days of heat stress (corresponds to short-term heat stress) and control period at TNZ. The present findings indicate that HSP70 is possibly involved in heat stress adaptive response in Tharparkar cattle and the biphasic expression pattern may be providing a second window of protection during chronic heat stress.

Abstract
We study the low-temperature electronic transport properties of single germanium nanowires (NWs) with diameters down to 45 nm to investigate the weak localization (WL) behavior and approach to metal-insulator transition (MIT) within them. The NWs (single crystalline) we investigate lie on the metallic side of the MIT with an extrapolated zero temperature conductivity [Formula: see text] in the range 23 to 1790 [Formula: see text] cm)-1 and show a temperature-dependent conductivity which below 30 K can be described by a 3D WL behavior with Thouless length [Formula: see text] and [Formula: see text]. From the observed value of [Formula: see text] and the value of the critical carrier concentration n c, it is observed that the approach to MIT can be described by the scaling equation [Formula: see text] with [Formula: see text], which is a value expected for an uncompensated system. The investigation establishes a NW size limit for the applicability of 3D scaling theories.

Abstract
We report the use of interface selective Second Harmonic generation technique to investigate the transport of the LDS cation across POPG liposomes in the pH range of 4.0 to 8.0 in the presence and absence of two amphiphilic drugs, Curcumin and Chlorin-p6 (Cp6). Our results show that bilayer permeability of liposomes is significantly affected by the presence of the drugs and pH of the medium as evidenced by significant changes in the transport kinetics of the LDS. Studies carried out in the pH range 4.0-8.0 show that while Cp6 significantly enhanced the transport of LDS at pH4.0, the transport of the cation was seen to increase with increasing pH, with maximum effect at pH7.4 for Curcumin. The pH dependent bilayer localization of both the drugs was investigated by conducting steady state FRET studies using DPH labeled lipids as donors. The FRET results and the relative population of the various ionic/nonionic species of the drugs at different pH suggest that distance dependent interaction between the various ionic species of the drugs and polar head groups of the lipid is responsible for the observed pH dependence enhancement of the drug induced membrane permeability. Another interesting observation was that the stability of Curcumin in presence of POPG liposomes was observed to degrade significantly near physiological pH (7.4 and 8.0). Although this degradation did not affect the liposome integrity, interestingly this was observed to enhance the transport of the LDS cation across the bilayer. That the degradation products of Curcumin are equally effective as the drug itself in enhancing the membrane permeability lends additional support to the current opinion that the bioactive degradation products of the drug may have a significant contribution to its observed pharmacological effects.

Abstract
Franciscana dolphins are the most impacted small cetacean in the Southwestern Atlantic Ocean, classified as Vulnerable A3d by IUCN. Essential (Fe, Mo, Mn, Cr, Ni, Co) and non-essential (Ag, Pb, Sn) trace elements (TEs) were measured in liver, kidney, and brain samples of by-catch Franciscana dolphins that were living in estuarine (n = 21) and marine (n = 21) habitats (1) to assess whether TEs posed a threat and (2) to evaluate the suitability of TEs for discriminating ecological populations of this species in Argentinean waters. Essential TEs showed little variation in tissues from both groups in agreement with levels reported for other cetaceans and suggesting that these concentrations correspond to normal physiological levels. Non-essential TEs were higher in estuarine juveniles and adults dolphins than in marine specimens. These results suggest anthropogenic sources associated with estuarine area and that Franciscana dolphins are good sentinels of the impact of the environment. The difference in the concentrations of TEs beetwen ecological populations appeared to be related to distinct exposures in both geographical areas, and it is suggested that Ag and Sn concentrations in adults are good chemical tracers of anthropogenic input of TEs. These results provide additional information for improved management and regulatory policy.

Abstract
Purpose To identify the variables and factors that affect the quantity and quality of nucleic acid yields from imaging-guided core needle biopsy. Materials and Methods This study was approved by the institutional review board and compliant with HIPAA. The authors prospectively obtained 232 biopsy specimens from 74 patients (177 ex vivo biopsy samples from surgically resected masses were obtained from 49 patients and 55 in vivo lung biopsy samples from computed tomographic [CT]-guided lung biopsies were obtained from 25 patients) and quantitatively measured DNA and RNA yields with respect to needle gauge, number of needle passes, and percentage of the needle core. RNA quality was also assessed. Significance of correlations among variables was assessed with analysis of variance followed by linear regression. Conditional probabilities were calculated for projected sample yields. Results The total nucleic acid yield increased with an increase in the number of needle passes or a decrease in needle gauge (two-way analysis of variance, P < .0001 for both). However, contrary to calculated differences in volume yields, the effect of needle gauge was markedly greater than the number of passes. For example, the use of an 18-gauge versus a 20-gauge biopsy needle resulted in a 4.8-5.7 times greater yield, whereas a double versus a single pass resulted in a 2.4-2.8 times greater yield for 18- versus 20-gauge needles, respectively. Ninety-eight of 184 samples (53%) had an RNA integrity number of at least 7 (out of a possible score of 10). Conclusion With regard to optimizing nucleic acid yields in CT-guided lung core needle biopsies used for genomic analysis, there should be a preference for using lower gauge needles over higher gauge needles with more passes. ©RSNA, 2016 Online supplemental material is available for this article.
