BACKGROUND: Limited data exist regarding the correlation between MRI tumour regression grade (mrTRG) and pathological TRG (pTRG) in rectal cancer. METHODS: mrTRG and pTRG were compared in rectal cancer patients from two phase II trials (EXPERT and EXPERT-C). The agreement between radiologist and pathologist was assessed with the weighted κ test while the Kaplan-Meier method was used to estimate survival outcomes. RESULTS: One hundred ninety-one patients were included...

Ebolavirus and Marburgvirus comprise two genera of negative-sense single-stranded RNA viruses that cause severe hemorrhagic fevers in humans. Despite considerable research efforts, the molecular events following Ebola virus (EBOV) infection are poorly understood. With the view of identifying host factors that underpin EBOV pathogenesis, we compared the transcriptomes of EBOV-infected human, pig and bat kidney cells using an RNAseq approach. Despite a significant difference in viral transcription/replication between the cell lines, all cells responded to EBOV infection through a robust induction of extracellular growth factors...

Postpartum psychiatric disorders represent a significant public health problem that has not been readily addressed, particularly in the primary care setting. As maternal mood and anxiety difficulties are associated with a number of adverse outcomes for the mother, her offspring and the family system, addressing these concerns during the perinatal period is of critical importance. Although researchers and clinicians have become increasingly aware of the problem, postpartum mood and anxiety disorders (PMADs) remain widely unrecognized and poorly understood by both patients and providers...

BACKGROUND: The continuing emergence, development and spread of pathogenic organisms that are resistant to antimicrobials are a cause of increasing concern. The control of antimicrobial resistance requires knowledge of factors causing antimicrobial resistance, good attitudes towards the intervention strategies as well as changes in antibiotic prescribing behavior of health workers. Hence, this study was aimed to assess paramedical staffs' knowledge and attitudes towards antimicrobial resistance and their antibiotics prescription practices in Dire Dawa, Ethiopia...

University students are especially vulnerable to poor sleep quality. The aim of this study was to assess students' sleep hygiene awareness and sleep hygiene practices, and evaluate their sleep quality. The association of sleep quality with sleep hygiene awareness and practice was also explored. The median sleep quality score was 7; scores more than 5 indicate poor sleep quality. Hence, a large proportion of Kuwait University students experience a suboptimal level of overall sleep quality according to the Pittsburgh Sleep Quality Index criteria...

Trait response-effects are critical to forecast community structure and biomass production in highly diverse tropical forests. Ecological theory and few observation studies indicate that trees with acquisitive functional traits would respond more strongly to higher resource availability than those with conservative traits. We assessed how long-term tree growth in experimental nutrient addition plots (N, P and N+P) varied as a function of morphological traits, tree size and species identity. We also evaluated how trait-based responses affected stand scale biomass production considering the community structure...

Acute myeloid leukemia (AML) with the FLT3 internal tandem duplication (FLT3-ITD AML) accounts for 20-30% of AML cases. This subtype usually responds poorly to conventional therapies, and might become resistant to FLT3 tyrosine kinase inhibitors (TKIs) due to molecular bypass mechanisms. New therapeutic strategies focusing on resistance mechanisms are therefore urgently needed. Pim kinases are FLT3-ITD oncogenic targets that have been implicated in FLT3 TKI resistance. However, their precise biological function downstream of FLT3-ITD requires further investigation...

Mantle cell lymphoma (MCL) may be one of the few cancers where multiple chemotherapy and non-chemotherapy regimens are considered as standard. Despite the significant activity of chemotherapy in the first-line setting and beyond, its limitations are reflected in the relatively poor ultimate outcomes of patients with MCL treated in the real world. Highly proliferative MCL and those with TP53 mutations tend to respond poorly despite intensive cytotoxic therapies. Patients with co-morbidities and those that are geographically isolated may not have access to the regimens that may appear most promising in clinical trials...

Current treatments and the dominant model of mental health care do not adequately address the complex challenges of mental illness, which accounts for roughly one-third of adult disability globally. These circumstances call for radical change in the paradigm and practices of mental health care, including improving standards of clinician training, developing new research methods, and re-envisioning current models of mental health care delivery. Because of its dominant position in the US health care marketplace and its commitment to research and innovation, Kaiser Permanente (KP) is strategically positioned to make important contributions that will shape the future of mental health care nationally and globally...

Breast cancer 1 (BRCA1), as a tumor suppressor, exerts an effective influence on protecting DNA integrity to suppress the development of breast cancer (BC). BRCA1 expression is induced in response to DNA-damaging agents such as etoposide. Germline BRCA1 gene mutations are associated with development of hereditary BC. However, besides BRCA-mutated BCs, some sporadic cancers may also exhibit a BRCA-like phenotype, displaying so-called 'BRCAness'. This common phenotype may respond to similar therapeutic approaches as BRCA-mutated tumors and may thus have important implications for the clinical management of these cancers...

BACKGROUND: Current treatments for chronic hepatitis B (CHB) include pegylated interferon alpha (PEG-IFN-α) which is an immune modulator, and nucleos(t)ide analogs (NAs) which directly inhibit HBV DNA polymerase. With the limited efficacy of PEG-IFN-α and prolonged treatment periods associated with NAs, there is an urgent need for novel therapeutic strategies, especially for patients with a poor early response to anti-viral therapy. METHODS: In this study, 178 patients with chronic hepatitis B (n = 131) and compensated (n = 47) HBV-induced cirrhosis were enrolled, 120 patients with HBeAg (+)...

Glioblastoma (GBM) is a very aggressive tumor that has not had substantial therapeutic improvement since the introduction of temozolomide (TMZ) in combination with radiotherapy. Combining TMZ with other chemotherapeutic agents is a strategy that could be further explored for GBM. To search for molecular predictors of TMZ resistance, the TCGA (The Cancer Genome Atlas) database was utilized to assess the impact of specific genes on TMZ response. Patients whose tumors expressed low levels of FGFR3 and AKT2 responded poorly to TMZ...

Antipsychotics are the main line of treatment for schizophrenia, a disorder that affects about 1% of the worldwide population. Considering the poor performance of antipsychotics on patients, this work aimed at detecting alterations in the elemental profile resulting from the use of this type of medication using an elemental fingerprinting strategy. We evaluated 56 plasma samples from schizophrenia patients by inductively coupled plasma mass spectrometry (ICP-MS) before (t0) and after 6 weeks (t6) of treatment...

BACKGROUND: Pre-operative chemoradiotherapy (CRT) for MRI-defined, locally advanced rectal cancer is primarily intended to reduce local recurrence rates by downstaging tumours, enabling an improved likelihood of curative resection. However, in a subset of patients complete tumour regression occurs implying that no viable tumour is present within the surgical specimen. This raises the possibility that surgery may have been avoided. It is also recognised that response to CRT is a key determinant of prognosis...

BACKGROUND: The nutrition transition has brought about rapid changes in the structure of the Indian diet. The replacement of traditional home-cooked meals with ready-to-eat, processed foods has contributed to an increased risk of chronic diseases in urban Indians. Improving the nutrition of Indians by promoting healthy food consumption in early life and in adolescence would help to reduce these health risks. However, little is known about the quality and quantity of foods and beverages consumed by urban Indian adolescents...

BACKGROUND/PURPOSE: The long-acting corifollitropin alfa is comparable to FSH in terms of pregnancy outcomes in normal responders and poor responders. Corifollitropin alfa has never been studied in polycystic ovary syndrome (PCOS) patients because of concerns of excessive ovarian stimulation and ovarian hyperstimulation syndrome (OHSS). The purpose of the study was to evaluate if corifollitropin alfa can be used in PCOS patients. METHODS: Forty PCOS patients who were going to undergo in vitro fertilization were enrolled in this study...

Gay and bisexual men (GBM) are more likely to attempt suicide than heterosexual men. This disparity is commonly interpreted using minority stress theory; however, specific pathways from antigay stigma to suicidal behavior are poorly understood. We aimed to estimate associations between multiple constructs of stigma and suicide attempts among adult GBM, and to measure the proportion of these associations mediated by distinct suicide risk factors, thus identifying proximal points of intervention. Data were drawn from a Canadian community-based survey of adult GBM...

Perianal fistulizing Crohn's disease has a major negative effect on patient quality of life and is a predictor of poor long-term outcomes. Factors involved in the pathogenesis of perianal fistulizing Crohn's disease include an increased production of transforming growth factor β, TNF and IL-13 in the inflammatory infiltrate that induce epithelial-to-mesenchymal transition and upregulation of matrix metalloproteinases, leading to tissue remodelling and fistula formation. Care of patients with perianal Crohn's disease requires a multidisciplinary approach...
