Abstract With an infection rate of 60–90%, the human cytomegalovirus (HCMV) is very common among adults but normally causes no symptoms. When T cell-mediated immunity is compromised, HCMV reactivation can lead to increased morbidity and mortality. HCMV antigens are processed and presented as peptides on the cell surface via HLA I complexes to the T cell receptor (TCR) of T cells. The generation of antibodies against HCMV peptides presented on HLA complexes (TCR-like antibodies)...

Abstract Natural killer (NK) cells are critically involved in anti-tumor immunity by targeting tumor cells. In this study, we show that intratumoral NK cells from NSCLC patients expressed elevated levels of the immune checkpoint receptor PD-1 on their cell surface. In contrast to the expression of activating receptors, PD-1+ NK cells co-expressed more inhibitory receptors compared to PD-1− NK cells. Intratumoral NK cells were less functional compared to peripheral NK cells, and...

Evidences for the personalized use of nonsteroidal anti-inflammatory drugs (NSAIDs) in colorectal cancer (CRC) prevention and treatment that include consideration of prostaglandin E2 levels are necessary. This study was designed as a case-control study including 60 CRC patients and 120 cancer-free controls. A sensitive empirical method, precolumn derivatization HPLC, was used to determine plasma PGE2 levels. The TaqMan SNP Genotyping Assay was used for the genotyping of prostaglandin-endoperoxide...

Introduction Haematological malignancies often escape the standard information flows of cancer registries because diagnosis is not always based on bone marrow histology but, rather, on other laboratory tests. Objective To quantify incident haematological malignancies identified exclusively through the laboratory information system and to measure the impact of that source on the sensitivity and accuracy of registering these malignancies. Methods We collected data from the only provincial...

Cancer is an unpleasant, painful disease. It is one of the most devastating diseases worldwide diminishing many lives. Many genetic and epigenetic changes occur before cancer develops. Mutation in SETD2 gene is one such example. RNA splicing, DNA damage repair, DNA methylation and histone methylation are some of the biological processes mediated by SETD2. SETD2 (histone H3 lysine 36 methyltransferase) is a frequently mutated gene in different types of cancer. Loss of SETD2 is associated with worse...

Background Cervical cancer has a high mortality rate worldwide; in Pakistan it kills more than 7000 women every year. Prevention is possible through vaccination against human papilloma virus, the causative agent of cervical cancer, or by screening for premalignant lesions through routine Pap smear tests. We have studied the knowledge and practices regarding cervical cancer, its risk factors, screening and prevention and the role of human papilloma virus vaccination and Pap smear testing, among...

IntroductionCognitive frailty (CF) is a clinical manifestation characterised by the simultaneous presence of both physical frailty and cognitive impairment among older adults without dementia and has become a new target for healthy ageing. Increasing evidence shows that regular Baduanjin (a traditional Chinese mind–body exercise) training is beneficial in improving physical function and cognitive ability in the older adults. The primary aim of this trial is to observe the effect of Baduanjin on physical...

ObjectiveTo quantify general practitioners’ (GPs) sensitivity to anxiety disorders (ADs) when confronted with the range of symptoms common to children with ADs. Also, to explore GPs’ conscious preferences and implicit tendencies for referral of children with ADs to mental healthcare. Design and settingIn a cross-sectional vignette-based survey, all attendees of a Dutch continuing medical education conference for primary care physicians were presented with subtitled audio fragments of five vignettes...

ObjectivesInhaled corticosteroids (ICS) reduce exacerbation rates and the decline in lung function in people with chronic obstructive pulmonary disease (COPD). There is evidence that smoking causes ‘steroid resistance’ and thus reduces the effect of ICS. This systematic review aimed to investigate the effect of smoking on efficacy of ICS in COPD in terms of lung function and exacerbation rates. DesignSystematic review. Data sourcesAn electronic database search of PubMed, Ovid MEDLINE, Ovid Embase...

IntroductionPrenatal anxiety is a prevalent condition that is harmful for women and a strong predictor of postpartum depression. This trial assesses an intervention initiated in early pregnancy to mid pregnancy among women with clinical or subclinical symptoms of anxiety in Pakistan. Methods and analysis Happy Mother, Healthy Baby (HMHB) is a phase three, two-arm, single-blind, individual randomised clinical trial conducted in the outpatient department of Holy Family Hospital, a large public tertiary...

A 72-year-old man presented with urinary retention, weight loss, haematuria and severe acute kidney injury. He had never before been admitted to hospital and his past medical history included only an inguinal hernia. On examination, he appeared uraemic and had a right-sided painful hernia. A three-way catheter was inserted, bladder washouts performed and irrigation started. An ultrasound showed severe bilateral hydronephrosis and a ‘thickened bladder’ and this was thought to be obstructive uropathy...

This case study discusses the dental management of a patient with a history of multiple myeloma and pulmonary aspergillosis, whom was referred to a hospital-based dental service for urgent dental review. The patient had received a dental assessment in primary care prior to commencement of chemotherapy and had four teeth extracted without complications. However, following the commencement of chemotherapy, he presented with a significant infection associated with two of his wisdom teeth resulting in...

A 45-year-old woman presented with diminished vision in the left eye. Visual acuity was 6/9 and fundus showed a very large live nematode near the macula along with inflammatory outer retinal lesions in the periphery. We diagnosed the case as diffuse unilateral subacute neuroretinitis and treated with immediate focal photocoagulation of the worm along with oral antihelminthic drugs and corticosteroids. The report highlights the importance of prompt laser and steroids in achieving good structural as...
