Biological research frequently involves the study of phenotyping data. Many of these studies focus on rare event categorical data, and in functional genomics typically study the presence or absence of an abnormal phenotype. With the growing interest in the role of sex, there is a need to assess the phenotype for sexual dimorphism. The identification of abnormal phenotypes for downstream research is challenged by the small sample size, the rare event nature, and the multiple testing problem, as many variables are monitored simultaneously...

BACKGROUND: Despite the lack of long-term results, peroral endoscopic myotomy (POEM) has been increasingly propagated as a feasible alternative to pneumatic balloon dilatation (BD) and laparoscopic Heller myotomy (LHM) in patients with achalasia. After a long-term follow-up, a large percentage of patients reported recurrence of dysphagia. It is unclear which kind of procedure (redo POEM or LHM) should be utilized in these patients with failed POEM. CASE REPORT AND RESULTS: We report the case of a 37-year-old female patient with type I achalasia who was successfully treated with LHM after a failed POEM procedure...

Hepatitis C virus (HCV) causes chronic infections in at least 150 million individuals world-wide. HCV has a narrow host range and robustly infects only humans and chimpanzees. The underlying mechanisms for this narrow host range are incompletely understood. At the level of entry differences in the amino acid sequences between the human and mouse orthologues of two essential host factors, the tetraspannin CD81 and the tight junction protein occludin (OCLN) explain at least in part HCV's limited ability to enter mouse hepatocytes...

The lack of epidemiological and environmental data on Brazilian indigenous populations is a challenge for the elaboration of public policy. This lack of data is more acute for "landless" indigenous groups. From this perspective, it was considered relevant to describe the Aranã, a landless indigenous group living in Minas Gerais, focusing on the demographic, socioeconomic and sanitary dimensions. A household survey was conducted. The data collected were analyzed and compared with those from other national ethnic groups...

Janus kinase (JAK) inhibitors have achieved positive responses in myeloproliferative neoplasms, but at the expense of decreased natural killer (NK) cell numbers and compromised function. Selective JAK2 inhibition may also have a role in preventing and treating graft-vs-host disease after allogeneic hematopoietic stem cell transplantation. Although JAK inhibitors can impair monocyte-derived dendritic cell (moDC) activation and function and suppress effector T-cell responses, the effects on NK cells and the relevant mechanisms remain undefined...

BACKGROUND: Kirschner wire (K-wire) fixation for correction of hammertoe deformity is the gold standard for hammertoe surgery fixation, the current study compares it to percutaneous surgery with 3M Coban dressings. METHODS: All hammertoe corrections performed were retrospectively reviewed. For the K-wire fixation group: resection arthroplasty of the proximal interphalangeal joint was performed and fixed with a K-wire. The percutaneous technique used involved percutaneous diaphyseal osteotomy of the middle and proximal phalanges combined with tendon release...

The breast is an unusual site for carcinoid metastasis. Due to increasing survival rates for carcinoid tumors, however, awareness of their rare complications is important. Carcinoid metastasis to the breast typically presents as a palpable breast mass or a mass on screening mammogram. Because imaging findings are nonspecific, the diagnosis is established through histological findings of neuroendocrine features corresponding with the known primary carcinoid pathology. Correctly distinguishing metastatic carcinoid from primary breast carcinoma is crucial to avoid more invasive procedures required for the latter...

Maurizio Pacilli, Mark Davenport
INTRODUCTION: Achalasia is a rare disorder in children who are commonly treated by laparoscopic Heller's myotomy (LHM). However, there are no large studies evaluating the results of LHM in the pediatric population, and the need of a concomitant fundoplication remains unclear. The aim of the study is to appraise the results of LHM based on a systematic literature review. MATERIALS AND METHODS: MEDLINE search of the English literature was performed for "achalasia," "children," "laparoscopy," "Heller," "myotomy," and "cardiomyotomy...

Cardiovascular diseases are one of the leading causes of morbidity and mortality in Germany. In these patients, the high-risk profile necessitates an interdisciplinary and multimodal approach to treatment. Endovascular interventions and vascular surgery have become established as an important element of this strategy in the past; however, the different anatomical localizations of pathological vascular alterations make it necessary to use a wide spectrum of procedural options and methods; therefore, the requirements for management of anesthesia are variable and necessitate a differentiated approach...

Dying and death in modern societies are subject to profound social, professional and cultural-religious changes. Secularization and a stronger differentiation of societies have led to a change in the way humans handle the dying process. Normatively ritualized collective behaviour has been replaced by an individual, subjectivized approach. In late modern societies there are many different views of what "successful" or "good" dying means.In the article this change is described by the following seven theses: 1...

We discover and characterise strong quantum scars, or quantum eigenstates resembling classical periodic orbits, in two-dimensional quantum wells perturbed by local impurities. These scars are not explained by ordinary scar theory, which would require the existence of short, moderately unstable periodic orbits in the perturbed system. Instead, they are supported by classical resonances in the unperturbed system and the resulting quantum near-degeneracy. Even in the case of a large number of randomly scattered impurities, the scars prefer distinct orientations that extremise the overlap with the impurities...

Achalasia cardia is a disorder of the gastrointestinal tract characterized by dilatation of the oesophagus and collection of food and fluids in the oesophagus leading to massive regurgitation and aspiration of gastric contents. Down's syndrome has multisystem effects which can also present as difficult airway. Here, we present a case of a 14-year-old girl, a case of Down's syndrome with Achalasia cardia and mitral valve prolapse posted for Heller's cardiomyotomy. Anaesthetic concerns were difficult airway due to Downs's syndrome, massive aspiration risks of Achalasia cardia and haemodynamic instability due to mitral regurgitation...

The disparity between the chronological age of an individual and their brain-age measured based on biological information has the potential to offer clinically-relevant biomarkers of neurological syndromes that emerge late in the lifespan. While prior brain-age prediction studies have relied exclusively on either structural or functional brain data, here we investigate how multimodal brain-imaging data improves age prediction. Using cortical anatomy and whole-brain functional connectivity on a large adult lifespan sample (N=2354, age 19-82), we found that multimodal data improves brain-based age prediction, resulting in a mean absolute prediction error of 4...

BACKGROUND: If patients are treated according to their personal preferences, depression treatment success is higher. It is not known which treatment options for late-life depression are preferred by patients aged 75 years and over and whether there are determinants of these preferences. METHODS: The data were derived from the German "Late-life depression in primary care: needs, health care utilization, and costs (AgeMooDe)" study. Patients aged 75+ years (N = 1,230) were recruited from primary care practices...
