INTRODUCTION The immune microenvironment plays an increasingly important role in predicting the prognosis of multiple tumors and selecting patients for immunotherapy trials. We studied the expression of indoleamine 2, 3-dioxygenase (IDO) and programmed death ligand-1 (PD-L1), detected the proportion of tumor-infiltrating immune cells (TIIs), and further analyzed the association of these immunological characteristics with the clinicopathological parameters and prognosis of breast cancer patients. METHODS Immunohistochemical staining for IDO, PD-L1, CD4, CD8, Foxp3, CD20, CD56 and CD68 expression in breast cancer tissues was carried out. IDO and PD-L1 expression were scored by extent in tumor cells. TIIs expressing CD4, CD8, Foxp3, CD20, CD56 or CD68 were evaluated by positive count. Clinicopathological characteristics and follow-up were recorded. RESULTS The frequencies of IDO-high-expressing and PD-L1-expressing tissue were 33.77% and 24.68%, respectively. The co-expression of IDO and PD-L1 was identified in 16/77 (20.78%) of cases. IDO high expression, CD4+ T cells and CD56+ cells were most frequently observed in patients with tumor-draining lymph nodes(TDLNs) metastasis. Immune cells were more common in non-luminal breast cancer than in luminal breast cancer. In survival analysis, PFS were not associated with high levels of IDO and PD-L1, nor were TIIs. However, CD20 and CD68 were significant risk factors for prognostic after adjusting covariates by COX regression. IDOhighFoxp3highT patients had a tendency with shorter progression-free survival. CONCLUSIONS Although we found a limited prognostic effect of TIIs on survival in breast cancer patients, IDO combined with TIIs can help to evaluate the prognosis of patients. The Indian health system is undergoing significant reform toward more evidence-informed and inclusive health policy as the country strives toward the achievement of Universal Health Coverage for its 1.3 billion population. Cost information plays a key role in the evidence arsenal of Universal Health Coverage-oriented policy by informing decisions such as the setting reimbursement rates for government-sponsored health insurance packages of care, strategic purchasing of health services, and in prioritizing available resources to maximize value of health sector investments. However, extensive and quality health facility cost data in India are limited. As a result, there is an increasing and urgent need to generate and disseminate healthcare cost information. This article discusses the need for cost information and the current initiatives that are progressing this agenda. The first is a national cost database and website hosting cost data collected from 200 public sector facilities across 6 Indian states at each level of the care delivery system by a consortium of health research institutes. This database is the first of its kind in India and will serve as a central resource for researchers and decision-makers for information on healthcare costs. The second is a nationwide costing study of healthcare at both private and public facilities. By improving the availability of cost data in India, raising its profile and demonstrating its utility, it is hoped that the database and new costing efforts will lead to greater recognition of the importance of good quality data to inform health policy and enable more evidence-informed decision-making. OBJECTIVES Low birth-weight is a major risk factor for perinatal death in sub-Saharan Africa, but the relative contribution of determinants of birth-weight are difficult to disentangle in low resource settings. We sought to delineate the relationship between birth-weight and maternal pre-eclampsia across gestation in a low-resource obstetric setting. STUDY DESIGN Prospective cohort study in a tertiary referral centre in urban Uganda, including 971 pre-eclampsia cases and 1461 control pregnancies between 28 and 42 weeks gestation. MAIN OUTCOME MEASURES Nonlinear modeling of birth-weight versus maternal pre-eclampsia status across gestation. Models were adjusted for maternal-fetal characteristics including maternal age, parity, HIV status, and socio-economic status. Propensity score matching was used to control for the severity of pre-eclampsia at different gestational ages. RESULTS Mean birth-weight for pre-eclampsia cases was 2.48 kg (±0.81SD) compared to 3.06 kg (±0.46SD) for controls (p less then 0.001). At 28 weeks, the mean birth-weight difference between pre-eclampsia cases and controls was 0.58 kg (p less then 0.05), narrowing to 0.17 kg at 39 weeks (p less then 0.01). Controlling for pre-eclampsia severity only partially explained this gestational difference in mean birth-weight between pre-eclampsia cases and controls. Holding gestational age constant, pre-eclampsia status predicted 7.1-10.5% of total variation in birth-weight, compared to 0.05-0.7% for all other maternal-fetal characteristics combined. CONCLUSIONS Pre-eclampsia is the dominant predictor of birth-weight in low-resource settings and hence likely to heavily influence perinatal survival. The impact of pre-eclampsia on birth-weight is smaller with advancing gestational age, a difference that is not fully explained by controlling for pre-eclampsia severity. V.Salicylic acid (SA) is a plant hormone essential for effective resistance to viral and non-viral pathogens. SA biosynthesis increases rapidly in resistant hosts when a dominant host resistance gene product recognizes a pathogen. SA stimulates resistance to viral replication, intercellular spread and systemic movement. However, certain viruses stimulate SA biosynthesis in susceptible hosts. This paradoxical effect limits virus titer and prevents excessive host damage, suggesting that these viruses exploit SA-induced resistance to optimize their accumulation. Recent work showed that SA production in plants does not simply recapitulate bacterial SA biosynthetic mechanisms, and that the relative contributions of the shikimate and phenylpropanoid pathways to the SA pool differ markedly between plant species. PURPOSE Sexual health is often neglected following a bone marrow transplant. The purpose of this study was to develop an in-depth explanation of the process that patients undergo when re-engaging in sexual relationships following a bone marrow transplant. METHODS A Straussian Grounded Theory methodology was employed. Ten bone marrow transplant patients (seven men, three women), participated in a semi-structured interview between October 2018 and April 2019. MK-0991 RESULTS A theoretical model of the process of re-engaging in a sexual relationship following a bone marrow transplant evolved over time. Four categories emerged from the data identifying importance, taking responsibility, seeking resources, and navigating the partnered-relationship. Gender-specific details permeated all of these categories. These occurred in a non-linear process of 'seeking a new normal' and could apply at any time point during the treatment trajectory. CONCLUSIONS The model offers an explanation of the process participants went through during their illness and identifies ways that participants navigated change.
