Abstract
Introduction In Fiji, multiple burdens of malnutrition including undernutrition, overweight/obesity, and micronutrient deficiencies coexist at the individual, household, and population levels. The diets of children, adolescents, and adults are generally unhealthy. The objective of this review was to understand how the dietary behaviors of children, adolescents, and women in Fiji are influenced by individual, social, and food environment factors. Methods This rapid review was conducted to synthesize existing evidence, identify research gaps in the evidence base, and make recommendations for future research. The Cochrane Rapid Reviews Methods and the updated guideline for reporting systematic reviews were used. The search strategy for this rapid review was based on the Population Context Outcome [P(E)CO] framework, including search terms for population (children, adolescents, and adults), context (Fiji), and outcome (dietary behaviors). Searches were conducted in PubMed, Scopus, PsycINFO, and Google Scholar. Results The 22 studies included in this review identified different factors influencing dietary behaviors in Fiji. Individual preferences for processed and imported foods, especially of younger generations, and social dynamics, especially gender norms and social pressure, to serve meat and overeat appeared to be prominent in driving dietary habits. The ongoing nutrition transition has led to increasing availability and affordability of ultra-processed and fast foods, especially in urban areas. Concerns about food safety and contamination and climate change and its effect on local food production also appear to influence dietary choices. Discussion This review identified different dynamics influencing dietary behaviors, but also research gaps especially with regard to the food environment, calling for an integrated approach to address these factors more systemically.

Abstract
INTRODUCTION A wandering spleen occurs when laxity or absence of the suspensory ligaments allows migration throughout the abdomen. Gastric outlet obstruction resulting from this abnormality is rare. We present a systematic literature search and a case that was managed successfully with surgical intervention at our centre. METHODS A systematic search of the PubMed, Embase™, Medline® and Google Scholar™ databases was carried out employing the combined search terms "gastric outlet obstruction" AND "wandering spleen". Six results were included for final analysis. RESULTS All six search results described a single case each. Patients underwent surgical management (open or laparoscopic) after initial investigation utilising a range of modalities. There were no mortalities reported at 90 days. The single case we present was complicated by gastric perforation; the patient made a successful recovery following open splenopexy and stapled wedge resection of the stomach. CONCLUSIONS A wandering spleen is a rare diagnosis and there are only six reported cases of gastric outlet obstruction secondary to a wandering spleen in the literature. None report associated gastric perforation. There are a variety of presenting symptoms, intraoperative findings and operative techniques used to address the gastrosplenic abnormality. The case reported by our centre adds to this limited evidence base and demonstrates a successful outcome from definitive surgical management. We highlight the need to seek early gastro-oesophageal expertise if any gastric pathology is found together with anatomical abnormality of the spleen.

Abstract
BACKGROUND Severe perinatal depression is a significant cause of mortality and morbidity in neonates. Vitamin D levels were observed to be low in mothers and their neonates with hypoxic ischemic encephalopathy in some studies, owing to its neuroprotective properties. OBJECTIVE Primary objective was to compare vitamin D deficiency state in full term neonates with severe perinatal depression and healthy term controls. Secondary objectives were to determine sensitivity and specificity of serum 25(OH)D<12 ng/mL in predicting mortality, development of hypoxic ischemic encephalopathy, abnormal neurological examination at discharge, and developmental outcome at 12 weeks of age. MATERIAL AND METHODS Serum 25(OH)D levels in full term neonates with severe perinatal depression and healthy controls were compared. RESULTS Serum 25(OH)D levels in severe perinatal depression and controls (n = 55 each group) were significantly different (7.50 ± 3.53 ng/mL vs 20.23 ± 12.70 ng/mL). At cut-off of < 12 ng/mL, serum 25(OH)D could predict mortality with 100% sensitivity and 17% specificity and poor developmental outcomes with sensitivity of 100% and specificity of 50% . CONCLUSION Vitamin D deficiency status at birth can serve as an effective screening tool and poor prognostic markers in term neonates with severe perinatal depression.

Abstract
Leiomyosarcoma is an unusual, malignant, mesenchymal neoplasm that is extremely rare in head and neck region. It clinically presents as a well-defined, painless mass which could easily be misdiagnosed as a benign lesion, posing a diagnostic challenge to the clinician. Head and neck leiomyosarcomas are very aggressive and have a poor prognosis. Hence, early diagnosis plays a vital role in its appropriate management.

Abstract
Background During neurosurgeries like resection of interhemispheric lipoma or cyst, surgeon needs to remain within the limits of interhemispheric fissure (IHF). Despite a massive literature search, data regarding the morphometry of IHF is meagre. Therefore, the present study was done to calculate the depth of IHF. Materials and Methods Twenty-five (fourteen male and eleven female) fresh human cadaveric brain specimens were used. The depth of IHF was measured from frontal pole; three points, anterior to coronal suture (A, B and C); four points, posterior to coronal suture (D, E, F and G) and from two points (via parieto-occipital sulcus and calcarine sulcus) on occipital pole. The measurements were taken from these points up to the floor of IHF. IHF is a midline groove and hence the measurements were taken from each point against both the left and the right cerebral hemispheres. At the end, not much bilateral asymmetry was found, hence the average of the reading for the same point against left and the right cerebral hemisphere was considered for calculation. Result Maximum depth was found to be 59.60 mm and minimum depth was found to be 19.66 mm among all the points which were considered for evaluation. No statistical difference was found in the depth of IHF among the male and the female groups as well as in the various age groups. Conclusion This data and knowledge about the depth of interhemispheric fissure will aid the neurosurgeons in order to perform the interhemispheric transcallosal approach as well as surgeries of interhemispheric fissure such as excision of lipoma, cyst, tumor of interhemispheric fissure through the shortest and the safest possible route.

Abstract
The morbidity rate following a surgical procedure increasing rapidly in the cases associated with surgical site infections. Traditional sutures lack the ability to deliver drugs as the incorporation of the drug in their structure would hamper their mechanical properties. To prevent such infections, we developed an extracellular matrix mimicking electrospun nanofibrous yarns of Poly-(D, L)-lactic acid and Polyvinyl alcohol loaded with Vancomycin and Ferulic Acid, prepared by uniaxial electrospinning technique. In-vitro characterization such as scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, tensile strength testing, degradation studies, and antimicrobial studies along with in-vivo evaluation done with help of incision wound healing rat model and simultaneous testing of microbial load in the incised tissue. The in-vitro studies indicated the nanofiber yarns have size range 200-300 nm with a tensile strength of 7.54±0.58 MPa. The dual drug-loaded yarn showed sustained drug release over a period of 48 hr. In-vitro water uptake and biodegradation data indicated optimum results suitable for suturing applications. Antimicrobial study showed excellent antimicrobial activity against both S. aureus and E. coli. Results obtained from in-vivo study suggested excellent wound healing potential of nanofiber yarns as compared with commercial silk sutures. The histopathological studies confirmed restoring ability of nanofiber yarn to the normal skin structure. ELISA study revealed the downregulation of inflammatory markers i.e. TNF-Alpha and IL-6, making nanofibers sutures suitable for surgical wound healing applications. Overall, the present study may conclude that the developed dual drug-loaded nanofiber yarns have excellent potential in surgical wound healing applications.

Abstract
BACKGROUND Management of hypercalcemia is based on the manifestation of symptoms and serum calcium levels. It is considered an oncological emergency; therefore, management has to be done on an urgent basis. AIM In the present study, we analyzed the clinicopathological profile, treatment, and outcome of patients with hypercalcemia in solid malignancies at our institute. METHODS We retrospectively analyzed the medical records of patients diagnosed with cancer and admitted to the department of radiation oncology with hypercalcemia. The parameters studied were age, gender, performance status, date of diagnosis, the primary site of cancer, stage, histopathology, time of presentation of hypercalcemia since initial cancer diagnosis, clinical symptoms, parathyroid hormone levels, liver and renal function tests, bone metastases, management, outcome, and present status. RESULTS In the present study, 47 patients of hypercalcemia from various solid malignancies were admitted during the study period between 1st January 2018 and 30th April 2022. Head and neck cancer (14, 29.7%) was the most common site of the primary malignancy. Twelve patients had incidental hypercalcemia and were asymptomatic. Management of hypercalcemia included intravenous saline hydration, bisphosphonates, and supportive medication. At the time of analysis, 17 patients were lost to follow-up, 23 patients died, and seven were alive and on follow-up. Median survival was 68.0 days (95% CI: 1.7-134.3 days). CONCLUSION Hypercalcemia of malignancy is considered a metabolic oncological emergency and requires urgent and aggressive management. It gets complicated by a deranged kidney function test. Despite available treatment, it portends an abysmal prognosis.

Abstract
This study was set up to assess the performance of the Reveal® rapid AST system to determine the drug susceptibility of Pseudomonas aeruginosa strains directly from blood cultures. Two hundred fully sequenced clinical P. aeruginosa strains were selected for the evaluation, of which 26.5% (n = 53) produced transferable β-lactamases, and 2.0 to 33.0% had susceptibility levels close to the EUCAST 2021 breakpoints of 11 commonly used antipseudomonal antibiotics. The Reveal® AST system was run with a commercial MIC microplate designed for fast-growing Gram-negative bacilli (Microscan Neg MDR MIC 1), and was compared to the manually operated GN6F MIC microdilution panel from Thermo Fisher, as a comparator method. The Reveal® AST system provided MIC results for the 11 antipseudomonal antibiotics tested within a mean time to result of 6 h 22 min. By comparison with the GN6F panel, the overall rates of categorical agreement (CA), very major errors (VME), major errors (ME), and minor errors (mE for meropenem only) were 96.1%, 1.6%, 4.2%, and 0.6%, respectively. The Specific Reveal® AST system appears to be a reliable and fast technology to determine the susceptibility of P. aeruginosa to antibiotics, including those with resistance levels near categorical breakpoints, directly from blood cultures.

Abstract
The goal of the current study is to comprehend the factors that influence a decision to use telemedicine for healthcare. India saw a massive surge in the use of telemedicine services in the year 2020-21, with teleconsultations increasing by almost 300%. Lockdowns and Covid-19 limitations sped up the introduction of telemedicine services. The advantages of telemedicine healthcare services, however, have not yet reached the vast majority of the population. A pilot survey is done, and a study framework is suggested, to better understand the factors that influence people's decisions to use telemedicine healthcare services. The following variables are taken into account for the study: personal norms, telemedicine use expectation, knowledge, telemedicine usage, initial satisfaction, and covid phobia -19 (CP-19). The suggested framework is then put to the test using SEM (Structural equation modelling), and a good model fit was found. Policymakers and marketers can use the findings to increase the acceptance of telemedicine healthcare services among the general public in order to promote convenience, accessibility, and healthy living.

Abstract
BACKGROUND During radiation therapy for head and neck malignancies, most patients experience significant anatomical alterations due to loss of weight, changes in tumor volumes, and immobilization issues. Adaptive radiotherapy adapts to the patient's actual anatomy through repetitive imaging and replanning. In the present study, dosimetric and volumetric changes in target volumes and organs at risk during adaptive radiotherapy in head and neck cancer was evaluated. MATERIAL AND METHODS Thirty-four locally advanced Head and neck carcinoma patients with histologically proven Squamous Cell Carcinoma for curative treatment were included. Rescan was done at the end of 20 fractions of treatment. All quantitative data were analyzed with paired t-Test and Wilcoxon Signed Rank (Z) test. RESULTS Most patients had oropharyngeal carcinoma (52.9%). There were significant volumetric changes in all the parameters - GTV-primary (10.95, p < 0.001), GTV- nodal (5.81, p = 0.001), PTV High Risk (26.1, p < 0.001), PTV - Intermediate Risk (46.9, p = 0.006), PTV - Low Risk (43.9, p = 0.003), lateral neck diameter (0.9, p < 0.001), right parotid volumes (6.36, p < 0.001) and left parotid volumes (4.93, p < 0.001). Dosimetric changes in the organs at risk were non-significant. CONCLUSION Adaptive replanning has been seen to be labour intensive. However, the changes in the volumes of both target and the OARs credit a mid-treatment replanning to be done. Long term follow-up is required to assess locoregional control after adaptive radiotherapy in head and neck cancer.

Abstract
The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02×10^{20} protons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by ≃17% systematic rather than the ≃7.4% statistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on Q^{2} (squared four-momentum transfer) and energy, in the range 1 GeV≤E_{ν}<6 GeV. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs Q^{2}.

Abstract
OBJECTIVE To explore the differentials of postpartum contraceptive adoption between rural and urban poor after adjusting for utilization of MCH services and other selected socioeconomic and demographic covariates. METHODS The data for this study is taken from the 4th round of NFHS survey conducted in India during 2015-16. The analysis is limited to 125,340 currently married women whose menses had returned at the time of survey. Discrete time complementary log-log multilevel model was applied. RESULTS: The results clearly indicate that women from rural areas had a lower chance of early initiation of modern spacing methods after having recent birth as compare to that of Urban Poor and Urban non-poor areas. The contributions of several socioeconomic and demographic characteristics that were important for family planning practice were also highlighted in this study. CONCLUSION There is an urgent need of designing an intervention that will result in effective delivery of services to achieve the greatest impact. Policy planners must focus on targeted interventions for family planning use in the postpartum period than simply focusing on family planning.

Abstract
High entropy alloys (HEAs) have gained interest for structural applications in extreme environments. With a potentially vast chemical and phase space, there are significant opportunities to discover superior performing alloys. Crucial for most high-temperature applications is understanding and mitigating the oxidation behavior of these chemically complex alloys. Most experimental and computational HEA studies have focused on a limited set of compositions and only a fraction of these compositions have been characterized for oxidation. We present a high-throughput framework that utilizes density-functional theory (DFT) in concert with a combined machine-learning model and grand-canonical linear programming for assessing phase stability, phase-fraction, chemical activity and high-temperature survivability of arbitrary HEAs. This framework considers temperature dependent contributions to the Gibbs energy of the competing phases arising from short-range order and vibrational entropy. We demonstrate the effectiveness of the framework by assessing the thermodynamic stability, oxidation behavior, chemical activity, and phase decomposition of body-centered cubic Mo-W-Ta-Ti-Zr refractory HEAs. A total of 51 compositions were analyzed and ranked in order of their survivability based on the Pareto-front analysis. Oxidation was performed at 1373 K on four samples in air showing the difference in oxidation behavior determined experimentally through scale thickness and their mass changes. The insights on oxidation behavior presented in this work will enable the fast assessment of technologically useful HEAs needed for future structural application in extreme conditions.

Phase Ib study of eprenetapopt (APR-246) in combination with pembrolizumab in patients with advanced or metastatic solid tumors. ESMO Open 2022; 7:100573. [PMID: 36084396 PMCID: PMC9588880 DOI: 10.1016/j.esmoop.2022.100573] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 06/23/2022] [Accepted: 08/02/2022] [Indexed: 11/04/2022] Open
Abstract
Background We conducted a phase I, multicenter, open-label, dose-finding, and expansion study to determine the safety and preliminary efficacy of eprenetapopt (APR-246) combined with pembrolizumab in patients with advanced/metastatic solid tumors (ClinicalTrials.gov NCT04383938). Patients and methods For dose-finding, requirements were non-central nervous system primary solid tumor, intolerant to/progressed after ≥1 line of treatment, and eligible for pembrolizumab; for expansion: (i) gastric/gastroesophageal junction tumor, intolerant to/progressed after first-line treatment, and no prior anti-programmed cell death receptor-1 (PD-1)/programmed death-ligand 1 (PD-L1) therapy; (ii) bladder/urothelial tumor, intolerant to/progressed after first-line cisplatin-based chemotherapy, and no prior anti-PD-1/PD-L1 therapy; (iii) non-small-cell lung cancer (NSCLC) with previous anti-PD-1/PD-L1 therapy. Patients received eprenetapopt 4.5 g/day intravenously (IV) on days 1-4 with pembrolizumab 200 mg IV on day 3 in each 21-day cycle. Primary endpoints were dose-limiting toxicity (DLT), adverse events (AEs), and recommended phase II dose (RP2D) of eprenetapopt. Results Forty patients were enrolled (median age 66 years; range 27-85) and 37 received eprenetapopt plus pembrolizumab. No DLTs were reported and the RP2D for eprenetapopt in combination was 4.5 g/day IV on days 1-4. The most common eprenetapopt-related AEs were dizziness (35.1%), nausea (32.4%), and vomiting (29.7%). AEs leading to eprenetapopt discontinuation occurred in 2/37 patients (5.4%). In efficacy-assessable patients (n = 29), one achieved complete response (urothelial cancer), two achieved partial responses (NSCLC, urothelial cancer), and six patients had stable disease. Conclusions The eprenetapopt plus pembrolizumab combination was well tolerated with an acceptable safety profile and showed clinical activity in patients with solid tumors. Eprenetapopt in combination with pembrolizumab was well tolerated with an acceptable safety profile. Eprenetapopt plus pembrolizumab demonstrated clinical activity in heavily pre-treated patients with solid tumors. This is the first clinical trial evaluating the combination of a p53 reactivator with immuno-oncology therapy. This work informs the development of treatment combining immunotherapy with agents targeting specific pathways such as p53.
