ABSTRACT
The aim of this study was to determine the 1- and 3-year overall survival rates. This prospective observational study was conducted at a tertiary care center in Bihar state, India. The study analyzed 228 patients in Bihar with a median age at diagnosis of 55 ± 12.05 years. The most common symptoms included upper abdominal pain (26.3%), weight loss (14%), and ascites (13.6%). The majority of patients presented at stage IV (72.8%), with liver metastasis being prevalent (61.4%). Interventional biliary drainage was performed in 9.6% of cases, and systemic chemotherapy was received by 84.64%, while 15.36% opted for best supportive care. Univariate Cox regression analysis identified Eastern Cooperative Oncology Group (ECOG) performance status, stage, gallstone disease, and surgical intervention as significant risk factors influencing overall survival (OS) (p < 0.001). Multivariate Cox regression analysis confirmed ECOG performance status (p < 0.001), stage (p = 0.039), and surgical intervention (p = 0.038) as independent factors impacting OS. One-year OS rates for stages II, III, and IV were 100%, 97%, and 44%, respectively, while 3-year OS rates were 29%, 4%, and 0%. Surgical intervention significantly influenced OS (p < 0.001). OS for surgical intervention was 28 months, and for inoperable cases, it was 12 months. One- and 3-year OS for surgical intervention were 95% and 11%, while for inoperable cases, they were 41% and 0%, respectively. Patients with gallbladder cancer, particularly in Bihar's Gangetic plains, face poor survival, especially with advanced disease. Adequate surgery improves outcomes, prompting a call for enhanced strategies, particularly for locally advanced GBC.

ABSTRACT
Phase Change Materials (PCMs) have demonstrated tremendous potential as a platform for achieving diverse functionalities in active and reconfigurable micro-nanophotonic devices across the electromagnetic spectrum, ranging from terahertz to visible frequencies. This comprehensive roadmap reviews the material and device aspects of PCMs, and their diverse applications in active and reconfigurable micro-nanophotonic devices across the electromagnetic spectrum. It discusses various device configurations and optimization techniques, including deep learning-based metasurface design. The integration of PCMs with Photonic Integrated Circuits and advanced electric-driven PCMs are explored. PCMs hold great promise for multifunctional device development, including applications in non-volatile memory, optical data storage, photonics, energy harvesting, biomedical technology, neuromorphic computing, thermal management, and flexible electronics.
ABSTRACT
BACKGROUND: With increasing incidence of cancer worldwide and increasing burden of treatment over the patients with cancer, the caregivers of those patients with cancer also suffer from psychological distress which ultimately affects their Quality of Life (QOL). This aspect is often overlooked which may ultimately lead to compromised patient care. PURPOSE: To translate the Caregiver Quality of Life Index-Cancer (CQOLC) Scale in Hindi and assess its association with Kesslers's psychological distress scale (K-10) for determining the quality of life (QoL) of caregivers of patients with cancer in India. METHODS: This is a single institute, hospital based cross sectional study performed from July 2020 to March 2021. Caregiver Quality of Life Index-Cancer (CQOLC) Scale, employing standard 'forward-backforward' translation procedure, the English-language version of the questionnaire was translated into Hindi-language by experts and administered to each caregiver. Cronbach's alpha was used for internal consistency. Kesslers's psychological distress scale (K-10) was analysed on interview basis. RESULTS: A total evaluated responders were 264. The hindi versions of the CQOLC was validated by cronbach's alpha method with internal consistency between 0.8 and 0.91. The majority of the caregivers were of the age group 31-40 yrs (42.05%). The male to female ratio was 6.54:1. CQOLC good score(0-45) was obtained in 27.27%, fair(46-90) in 55.30% and poor(91-140) in 17.42%. For K-10 distress scale very mild(10-19), mild(20-24), moderate(25-29) and severe(30-50) was observed in 47.73%, 11.74%, 11.74% and 28.79% respectively. A strong relation was found between the caregivers with poor CQOLC score and severe K-10 score(p<0.001). CONCLUSION: The Hindi version of CQOLC was accepted and its correlation with the point psychological distress predictor (K-10) scale was a valuable method to identify caregivers with poor QOL and severe distress levels.

Background: Treatment for coronavirus disease 2019 (COVID-19) pneumonia remains largely supportive till date and multiple clinical trials took place within the short span of time to evaluate the role of investigational therapies. The anti-inflammatory effect of low dose whole lung radiation in treating pneumonia has been documented earlier. This clinical trial analyzed the effect of low dose radiation therapy (LDRT) in a moderately affected COVID-19 pneumonia patient cohort and has evaluated its effect in stopping the conversion of moderate disease into severe disease. Methods: Patients with moderate COVID-19 pneumonia as characterized by the Ministry of Health and Family Welfare (MOHFW), Government of India, were randomized (1:1) to low dose whole lung radiation versus no radiation. All treatment of patients was concurrently being given as per institutional protocol. Patients were followed up with clinical and laboratory parameters monitored on Days 1, 3, 7, and 14. Computed tomography scan (CT scan) of thorax was performed on Days 1 and 7. Patients were evaluated for conversion of moderate into severe disease as per National Early Warning Score-2 (NEWS-2 score) as the primary end point. The secondary endpoints included changes in ratio between peripheral capillary oxygen saturation and fraction of inspired oxygen (SpO2/FiO2), biochemical markers, 25-point CT severity score, and radiation induced acute pulmonary toxicities. Findings: At the interim analysis, there were seven patients in the radiation arm and six in the control. A whole lung LDRT improved the outcome of SpO2/FiO2 at Day 3; however it did not convert into a statistically significant improvement for the NEWS-2 score. The serum levels of LDH, CRP, Ferritin and D-dimer were significantly reduced on 14 days in the LDRT arm in comparison to the baseline value but were not significant between the two groups. Interpretation: LDRT seems to have the potential to prevent moderate COVID-19 pneumonia from a deteriorating to severe category. However, further randomized clinical trial with an adequate number of such patients is warranted to establish the definitive role of LDRT in the management of COVID-19 pneumonia. Funding: An intramural research project bearing code: I-27/621, was sanctioned from the All India Institute of Medical Sciences, Patna, India.

With the emergence of second wave of COVID-19 infection globally, particularly in India in March-April 2021, protection by massive vaccination drive has become the need of the hour. Vaccines have been proved to reduce the risk of developing severe illness and are emerging as vital tools in the battle against COVID-19. As per the GLOBOCAN database, nearly 19.3 million new cancer cases have been reported in 2020 globally, which posed a significant challenge to health care providers to protect such large number of 'vulnerable' patients from COVID-19. Nevertheless, a considerable degree of doubt, hesitancy and misconceptions are noted regarding the administration of vaccines particularly during active immuno-suppressant treatment. This review article highlights the added vulnerability of cancer patients to the COVID-19 infection and has explored the immunological challenges associated with malignancy, anticancer treatment and COVID-19 vaccination.

PURPOSE: This study was conducted to assess the correlation between lymph node ratio (LNR) and prognosis of non-metastatic invasive breast carcinoma. METHOD: This retrospective study examined 455 patients who were diagnosed with non-metastatic, unilateral invasive breast carcinoma and underwent either breast conservative surgery (BCS) or modified radical mastectomy (MRM) with axillary lymph node dissection (ALND) with at least one lymph node identified in the ALND specimen. Receiver operating characteristics (ROC) curve analysis was used to find out predictive cut-off values of the LNR and negative lymph nodes (NLN). RESULTS: The median follow-up duration was 38 months. The median DFS and OS were 68 months and 72 months, respectively. 25.1% of patients had reported recurrence. The optimal cut-off value of LNR was 0.40. LNR was found to correlate significantly with pathological T (p < 0.001), pathological N (p < 0.001), and NLN (p < 0.001). Univariate analysis of the patients showed that the age group ≤ 35 years, menstrual status, pathological T, nodal status, lymphovascular invasion (LVI), perineural invasion (PNI), tumor grade, estrogen receptor (ER), progesterone receptor (PR), molecular subtypes, LNR, and NLN can affect disease-free survival (DFS) (p < 0.05) and OS (p < 0.05). Multivariate analysis showed that the pathological T (p < 0.001), menstrual status (p = 0.030), and LNR (p < 0.001) were the independent prognostic factors for DFS. Pathological T (p < 0.001) and LNR (p < 0.001) were the independent prognostic factors affecting OS. CONCLUSION: LNR is the independent prognostic factor of DFS and OS for non-metastatic breast carcinoma.

Vulvar carcinoma is a rare and aggressive gynecological malignancy. It affects elderly females, with the mean age at diagnosis being 55-60 years. Regional metastasis to inguinal lymph nodes is common. There is a high incidence of pelvic node involvement, especially in those with pathologically positive inguinal nodes. Surgery appears to be the only curative treatment option in the early stages of the disease. But in most patients, surgery is associated with considerable morbidities and psychosexual issues. Hence, in the quest for a less morbid form of treatment, multimodality approaches with various combinations of surgery, chemotherapy, and radiation therapy have been suggested for advanced vulvar cancers. Due to the low incidence of the disease, the level of evidence for the success of these treatment modalities is poor. In countries like India, a heterogeneous incidence of vulvar carcinoma exists across the country, with patients presenting at advanced stages when the option of surgery is often supplemented or replaced by chemotherapy and radiotherapy. In this review, we attempt to study the available published literature and trials and discuss the treatment options in various stages of vulvar carcinoma.
ABSTRACT
This is a case report of a 60-year-old diabetic, hypertensive male with a good performance status and a history of bilateral interstitial lung disease with a left upper lobe lung mass diagnosed to be a Stage IIB mixed small-cell/squamous cell carcinoma which was refractory to carboplatin- and etoposide-based chemotherapy. The patient was then taken up for adaptive intensity-modulated radiotherapy with tighter margin under image guidance with a mid-treatment replanning done at 25#. Acute toxicities were assessed weekly and showed no Grade 3 or more reactions. Pulmonary function test showed no detrimental changes during or after radiation. Response assessment at 12 and 20 weeks showed a partial response with decrease in metabolic activity on serial scans.
