Candidemia in neonatal intensive care unit: a cause of concern

Background: Candidemia in neonates is a serious and common cause of late onset sepsis. Candida species are the third most frequent organism isolated in late onset sepsis in very low birth weight (VLBW) infants (i.e., <1,500 g). Methods: This study was performed to evaluate epidemiology, species distribution, antifungal susceptibility and outcome of candida blood stream infections at a tertiary care centre.Results: About 1-2 ml of blood was collected aseptically in suspected cases of septicaemia and inoculated in 20 ml of Brain Heart Infusion(BHI) broth. Candida species isolates were confirmed by germ tube production, chlamydospore formation on corn meal agar(HiMedia), pigmentation on Hichrome Candida differential agar (Himedia), and carbohydrate assimilation tests. Non-albicans candida spp. are of special concern, due to their high virulence and low azole susceptibility characteristics, augmenting the high mortality rates.Conclusions: The emergence on non-albicans Candida merits attention as they display higher degree of resistance to azoles and are associated with higher mortality rates. Additional studies are required to define more accurately the prevalence and sensitivity pattern of Candida spp. which may serve as a template for development of preventive and therapeutic strategies for neonatal candidemia especially at peripheral health centres

Beyond Negativity: Re-Analysis and Follow-Up Experiments on Hope Speech Detection

Health experts assert that hope plays a crucial role in enhancing individuals' physical and mental well-being, facilitating their recovery, and promoting restoration. Hope speech refers to comments, posts and other social media messages that offer support, reassurance, suggestions, inspiration, and insight. The detection of hope speech involves the analysis of such textual content, with the aim of identifying messages that invoke positive emotions in people. Our study aims to find computationally efficient yet comparable/superior methods for hope speech detection.

Oligomenorrhoea (24%) was found to be significant symptom with P value of <0.05. TBPCR and CBNAAT were found to be statistically significant with P value of <0.001 for diagnosing FGTTB.Conclusions: We concluded that genital tuberculosis is paucibacillary disease, TBPCR and CBNAAT appears to be rapid and sensitive diagnostic modality

Foetomaternal Outcome in Pregnancy with Burn Injury: A Prospective Cohort Study

Introduction: Pregnancy is a state of an altered physiological process, and a burn injury during pregnancy, serves as an additive factor to this stressful state, such that it can directly or indirectly affect the feto-maternal outcome. Aim: To find out the effects of burn injury in pregnant females, in terms of maternal and foetal outcomes. Materials and Methods: This was a prospective cohort study, done in collaboration with the Department of Surgery at Rajashri Dashrath Autonomous State Medical College, Ayodhya, Uttar Pradesh, India, from September 2019 to November 2021, on 22 pregnant patients. All 22 confirmed cases of pregnancy with burn injury were included. Cases were evaluated in terms of age-wise distribution, parity, gestational age/ trimester of pregnancy, cause of burn injury, Total Body Surface Area (TBSA) distribution, the relation of TBSA distribution with foetal and maternal mortality, and events associated with the burn injury. Data was analysed using trial version of Statistical Package for Social Sciences (SPSS) version 22.0. Results: Mean age of pregnant patients with burns was 25.22±2.3 years. Thirteen (59.09%) patients with burn injuries were married for one to three years, incidence was more in primigravidae 14 (63.63%). Domestic violence and suicide attempts accounted for 12 (54.54%) cases. Kerosene and gas explosions were a major cause of burn injury, that is 16 (72.72%)and 5 (22.72%) respectively. Sixteen (72.72%) patients had burns with TBSA between 31-50%. Foetal mortality was 15 (68.18%) and maternal mortality was 14 (63.63%). Conclusion: Feto-maternal outcome was directly related to TBSA involved in burns. Illiteracy, and cultural practices like the use of earthen lamps, wood, and charcoal used for cooking, were some of the important causes of burn injury

Analgesic Activity of Hydroalcoholic Leave Extract of the Putranjiva roxburghii.

Background: this study was aimed to assess the possible analgesic activity of Putranjiva Roxburghii in albino’s Wister rats. Method: Rats were divided in 5 groups of 6 animal each, I group served as control, II group as standard (Pentazocin) while group III, IV and V were treated with leaves extract of Putranjiva Roxburghii at doses of 20,100,200 and 400 mg/kg respectively. The statistical analysis of results were carried out using and one way (ANOVA) followed by students t-test. Result and Discussion: the analgesic activity was determined based on the reaction time.

Breast cancer hypofractionated radiotherapy in 2-weeks with 2D technique: 5-year clinical outcomes of a phase 2 trial

BACKGROUND: To report clinical outcomes and late toxicities of a 2-week hypofractionated post-operative loco-regional radiotherapy in patients with breast cancer. MATERIALS AND METHODS: This trial was approved by the Institutional Ethics Committee and registered with gov, no. NCT02460744. Between June 2013 and October 2014, 50 patients with breast cancer, post mastectomy or breast conserving surgery (BCS) were included in this study, of whom 10 had BCS. Patients were planned on a 2-dimentional (2D) simulator with 2 tangential fields and an incident supraclavicular field. Radiotherapy dose was 34 Gy/10#/2 weeks and a sequential boost of 10 Gy/5#/1 wk in BCS patients. The primary endpoint was the rate of acute skin toxicities previously reported. Here, we report the secondary end points of late toxicities, cosmesis, local recurrence, disease-free survival (DFS) and overall survival (OS). Late skin toxicities were recorded according to the Radiotherapy and Oncology Group (RTOG) scoring criteria. Cosmetic outcomes were assessed using the Harvard/National Surgical Adjuvant Breast and Bowel Project (NSABP)/RTOG breast cosmesis and the Late Effects Normal Tissue/Subjective Objective Management Analytic (LENT/SOMA) scales for the breast and chest wall, respectively. Kaplan-Meier estimates of DFS and OS were calculated, and 5-year DFS and OS rates (with approximate 95% CIs) were estimated. RESULTS: Late grade ≥ 2 chest wall induration, hypopigmentation and subcutaneous fibrosis were seen in 3 (6%), 3 (6%) and 1 (2%) patients, respectively. Chest wall cosmesis was excellent/good in 34 (72%) and fair/bad in 13 (28%) patients. In BCS patients, grade 2 skin induration, subcutaneous fibrosis and edema was observed in 1 patient (11%) each. Cosmesis was excellent/good in 7 (78%) and fair/bad in 2 (22%) patients. Late grade ≥ 2 arm edema, pain and shoulder stiffness were reported by 1 (2%), 2 (4%) and 2 (4%) patients, respectively. No local recurrences were observed. Five patients developed distant metastases (10%). Seven patients died (14%). The 5-year DFS and OS rate was 90% (95% CI: 77–96%) and 88% (95% CI: 75–94%), respectively. CONCLUSION: Hypofractionated radiotherapy in 2 weeks in patients with breast cancer was associated with minimal late toxicity, good cosmetic outcome and excellent local control. This trial may be of relevance for developing countries where resources are limited.

Sustainable Management of National Parks and Protected Areas for Conserving Biodiversity in India

Habitat loss due to human activities and climate change is synergistically posing serious threats to the global biodiversity leading to irreversible extinction of several species. In wake of recent extinction, several forests are declared as protected areas where no more human activities are allowed. However, the scope of these protected areas got broadened from mere conservation to poverty alleviation and sustainable development during the past decades. Though these protected areas seem to be supportive of the biodiversity conservation, several challenges and gaps have emerged that need to be addressed for effective conservation and sustainable management in these protected areas. Therefore, the present chapter aims to address the roles, challenges, and approaches for conservation, and sustainable management in protected areas of India. Based on the published literature, we have found that protected areas proved to be a successful strategy for the conservation of wild animals and plants. However, management of poaching, man-wildlife conflicts, funding, extensive resource use, and tourism is still a challenge for some national parks of the country. Although governmental policies have addressed some of these challenges, only limited success has been achieved so far. Therefore, further studies need to assess the efficiency of protected areas for biodiversity conservation and devise the mechanisms for effective sustainable management of these protected areas

Role of cytokine in malignant T-cell metabolism and subsequent alternation in T-cell tumor microenvironment

T cells are an important component of adaptive immunity and T-cell-derived lymphomas are very complex due to many functional sub-types and functional elasticity of T-cells. As with other tumors, tissues specific factors are crucial in the development of T-cell lymphomas. In addition to neoplastic cells, T- cell lymphomas consist of a tumor micro-environment composed of normal cells and stroma. Numerous studies established the qualitative and quantitative differences between the tumor microenvironment and normal cell surroundings. Interaction between the various component of the tumor microenvironment is crucial since tumor cells can change the microenvironment and vice versa. In normal T-cell development, T-cells must respond to various stimulants deferentially and during these courses of adaptation. T-cells undergo various metabolic alterations. From the stage of quiescence to attention of fully active form T-cells undergoes various stage in terms of metabolic activity. Predominantly quiescent T-cells have ATP-generating metabolism while during the proliferative stage, their metabolism tilted towards the growth-promoting pathways. In addition to this, a functionally different subset of T-cells requires to activate the different metabolic pathways, and consequently, this regulation of the metabolic pathway control activation and function of T-cells. So, it is obvious that dynamic, and well-regulated metabolic pathways are important for the normal functioning of T-cells and their interaction with the microenvironment. There are various cell signaling mechanisms of metabolism are involved in this regulation and more and more studies have suggested the involvement of additional signaling in the development of the overall metabolic phenotype of T cells. These important signaling mediators include cytokines and hormones. The impact and role of these mediators especially the cytokines on the interplay between T-cell metabolism and the interaction of T-cells with their micro-environments in the context of T-cells lymphomas are discussed in this review article

Advanced Virgo Plus: Future Perspectives

While completing the commissioning phase to prepare the Virgo interferometer for the next joint Observation Run (O4), the Virgo collaboration is also finalizing the design of the next upgrades to the detector to be employed in the following Observation Run (O5). The major upgrade will concern decreasing the thermal noise limit, which will imply using very large test masses and increased laser beam size. But this will not be the only upgrade to be implemented in the break between the O4 and O5 observation runs to increase the Virgo detector strain sensitivity. The paper will cover the challenges linked to this upgrade and implications on the detector's reach and observational potential, reflecting the talk given at 12th Cosmic Ray International Seminar - CRIS 2022 held in September 2022 in Napoli

The Advanced Virgo+ status

The gravitational wave detector Advanced Virgo+ is currently in the commissioning phase in view of the fourth Observing Run (O4). The major upgrades with respect to the Advanced Virgo configuration are the implementation of an additional recycling cavity, the Signal Recycling cavity (SRC), at the output of the interferometer to broaden the sensitivity band and the Frequency Dependent Squeezing (FDS) to reduce quantum noise at all frequencies. The main difference of the Advanced Virgo + detector with respect to the LIGO detectors is the presence of marginally stable recycling cavities, with respect to the stable recycling cavities present in the LIGO detectors, which increases the difficulties in controlling the interferometer in presence of defects (both thermal and cold defects). This work will focus on the interferometer commissioning, highlighting the control challenges to maintain the detector in the working point which maximizes the sensitivity and the duty cycle for scientific data taking
