Plastic pollution is a major anthropogenic contaminant effecting the marine environment and is often associated with high human population densities and industrial activities. The microplastic (63 to 5000μm) burden of beach sediment and surf-zone water was investigated at selected sites along the entire length of the South African coastline. It was predicted that samples collected in areas of high population density, would contain a higher microplastic burden than those along coasts that demonstrate very low population densities...

Histiocytosis X is an idiopathic disease, characterized by a disorder of the reticulo-endothelial system in the human body. Histopathological studies carried out right from the 1800s have seen a significant similarity in the pathologic process of different stages in particular clinical syndromes showing proliferation of mature histiocytes. It was then modified by Lichenstein in 1953 as "Histiocytosis X". The exact aetiology is unknown; hence, the name "Histiocytosis X". The disease classically presents with three syndromes namely Eosinophilic granuloma, Letterer-Siwe disease and Hand-Schuller-Christian disease...

BACKGROUND: Non-governmental organizations (NGOs) have a key role in improving health in low- and middle-income countries. Their work needs to be synergistic, complementary to public services, and rooted in community mobilization and collective action. The study explores how an NGO and its health services are perceived by the population that it serves, and how it can contribute to reducing barriers to care. DESIGN: A qualitative exploratory study was conducted in remote Ecuador, characterized by its widespread poverty and lack of official governance...

This research proposes a substrate-integrated waveguide (SIW) cavity sensor to detect several chemicals using the millimeter-wave frequency range. The frequency response of the presented SIW sensor is switched by filling a very small quantity of chemical inside of the fluidic channel, which also causes a difference in the effective permittivity. The fluidic channel on this structure is either empty or filled with a chemical; when it is empty the structure resonates at 17.08 GHz. There is always a different resonant frequency when any chemical is injected into the fluidic channel...

OBJECTIVES: A substantial proportion of women who undergo an abortion continue afterwards without switching to more effective contraceptive use. Many subsequently have repeat unintended pregnancies. This study, therefore, aimed to identify and describe health professionalś experiences of providing contraceptive counselling to women seeking an abortion. METHODS: We interviewed 21 health professionals (HPs), involved in contraceptive counselling of women seeking abortion at three differently sized hospitals in Sweden...

A novel perturbation approach using additional metalized via-holes for implementation of the dual-band or wide-band dual-mode substrate integrated waveguide (SIW) filters is proposed in this paper. The independent perturbation on the first resonant mode TE101 can be constructed by applying the proposed perturbation approach, whereas the second resonant mode TE102 is not affected. Thus, new kinds of dual-band or wide-band dual-mode SIW filters with a fixed or an independently reconfigurable low-frequency band have been directly achieved...

BACKGROUND AND OBJECTIVE: The approval of sofosbuvir offers new therapeutic options for patients suffering from chronic hepatitis C. In phase III trials, it has demonstrated significantly greater efficacy and safety in comparison with the old standard of care. In addition, it provides the first interferon-free regimen allowing treatment of patients without previous therapeutic options. A current debate regarding pricing and affordability can be attributed to high treatment costs. The objective of this review was to compare health economic evaluations of sofosbuvir for the treatment of chronic hepatitis C in terms of models, patient populations, interventions and results...

Langerhans cell histiocytosis syndromes have been described as encompassing a range of disorders, such as eosinophilic granuloma, Letterer-Siwe syndrome and Hand-Schüller-Christian disease. These disorders have been mainly diagnosed at early ages of life and are relatively rare entities in adult age groups. In this study, we aimed to retrospectively evaluate the patients with Langerhans cell histiocytosis followed-up in our hospital. Seven patients were treated between 1995 and 2005. Median age of patients was 27...

The aim of the present study was to explore occupational differences in the experience of engagement both with regard to differences in the level of work engagement as well as in the predicting value of different antecedent variables. Multigroup latent mean analysis was performed on eight different occupational groups in Norway (lawyers, physicians, nurses, teachers, church ministers, bus drivers, and people working in advertising and information technology; N = 3,475). Tests for factorial invariance supported the use of the Oldenburg Burnout Inventory scale across occupational groups and that the latent means were comparable across the groups...

BACKGROUND: In the development of search strategies for systematic reviews, "conceptual approaches" are generally recommended to identify appropriate search terms for those parts of the strategies for which no validated search filters exist. However, "objective approaches" based on search terms identified by text analysis are increasingly being applied. AIM: To prospectively compare an objective with a conceptual approach for the development of search strategies...

Gynaecologists are in a position to challenge norms about gender and sexuality in relation to female genitals. Through their work they have the opportunity to educate patients, which is why teaching medical students to perform examinations in a gender sensitive way is significant. Medical students performing their first pelvic examination often experience the examination as uncomfortable because it is a body part that is connected to sex and to something private. This paper uses medical students' interpretations of performing their first pelvic examination as a means to discuss how cultural norms for gender, sexuality and female genitals affect these examinations...

The normal values of nasal dimensions and position have been established for various racial and ethnic groups. Unfortunately, there is a dearth of information related to these values in South Indian females, leading to surgeons being forced to use statistical data from Caucasians in their decision making. The objective of the present study was to compare statistically the nasal anthropometric measurement of South Indian women (SIW) with published norms for North American white women (NAWW) using independent t-test...

Langerhans cell histiocytosis (LCH), also known as histiocytosis X, is a group of rare disorders characterized by the continuous replication of a particular white blood cell called Langerhans cells. These cells are derived from the bone marrow and are found in the epidermis, playing a large role in immune surveillance and the elimination of foreign substances from the body. Additionally, Langerhans cells are capable of migrating from the skin to lymph nodes, and in LCH, these cells begin to congregate on the bone, particularly in the head and neck region, causing a multitude of problems...

Langerhans cell histiocytosis (LCH), formerly known as histiocytosis X, refers to a spectrum of diseases characterized by idiopathic proliferation of histiocytes that produce either focal (localized LCH) or systemic manifestations (Hand-Schüller-Christian disease and Letterer-Siwe disease). Localized LCH accounts for approximately 60-70 % of all LCH cases. Osseous involvement is the most common manifestation and typically involves the flat bones, along with lesions of the skull, pelvis, and ribs. Localized LCH in bone shows a wide spectrum of clinical manifestations and radiologic features that may mimic those of infections as well as benign and malignant tumors...

BACKGROUND: There is widespread recognition of the problem of unsafe care and extensive efforts have been made over the last 15 years to improve patient safety. In Sweden, a new patient safety law obliges the 21 county councils to assemble a yearly patient safety report (PSR). The aim of this study was to describe the patient safety work carried out in Sweden by analysing the PSRs with regard to the structure, process and result elements reported, and to investigate the perceived usefulness of the PSRs as a tool to achieve improved patient safety...

INTRODUCTION: Despite high access to contraceptive services, 42% of the women who seek an abortion in Sweden have a history of previous abortion(s). The reasons for this high repeat abortion rate remain obscure. The objective of this study was to study the choice of contraceptive method after abortion and related odds of repeat abortions within 3-4 years. MATERIAL AND METHODS: This is a retrospective cohort study based on a medical record review at three hospitals in Sweden...
