OBJECTIVES: This study aimed to provide an empirical model of predicting low back pain (LBP) by considering the occupational, personal, and psychological risk factor interactions in workers population employed in industrial units using an artificial neural networks approach. METHODS: A total of 92 workers with LBP as the case group and 68 healthy workers as a control group were selected in various industrial units with similar occupational conditions. The demographic information and personal, occupational, and psychosocial factors of the participants were collected via interview, related questionnaires, consultation with occupational medicine, and also the Rapid Entire Body Assessment worksheet and National Aeronautics and Space Administration Task Load Index software...

The aim of this study was to investigate the nature and extent of deliberate self-harm (DSH) amongst those attending national crisis centres in Ireland, and to assess clients' views of the service. A secondary analysis was undertaken of a large data set of clients presenting with DSH (n=823). Clients were predominantly female, under 25 and with self-cutting widely reported (73%). DSH co-occurred with suicidal ideation (SI) (42%) and/or a suicide attempt (SA) (35%). Males were significantly more likely to present with more severe problems, and to use more dramatic methods of DSH; more severe presenting issues were also significantly associated with a history of having friends who engage in DSH...

Plan Sésame (PS) is a user fee exemption policy launched in 2006 to provide free access to health services to Senegalese citizens aged 60 and over. Analysis of a large household survey evaluating PS echoes findings of other studies showing that user fee removal can be highly inequitable. 34 semi-structured interviews and 19 focus group discussions with people aged 60 and over were conducted in four regions in Senegal (Dakar, Diourbel, Matam and Tambacounda) over a period of six months during 2012. They were analysed to identify underlying causes of exclusion from/inclusion in PS and triangulated with the household survey...

In "The Origin of Species," Darwin describes a hypothetical example illustrating that large, slowly reproducing mammals such as the elephant can reach very large numbers if population growth is not affected by regulating factors. The elephant example has since been cited in various forms in a wide variety of books, ranging from educational material to encyclopedias. However, Darwin's text was changed over the six editions of the book, although some errors in the mathematics persisted throughout. In addition, full details of the problem remained hidden in his correspondence with readers of the Origin...

Uncovering the hidden diversity and evolutionary history of arthropods of medico-veterinary importance could have significant implications for vector-borne disease control and epidemiological intervention. The buffalo fly Haematobia exigua is an obligate bloodsucking ectoparasite of livestock. As an initial step towards understanding its population structures and biogeographic patterns, we characterized partial cytochrome c oxidase subunit I (COI) and cytochrome b (Cytb) sequences of H. exigua from three distinct geographic regions in Southeast Asia...

Bacteria exploit an arsenal of antimicrobial peptides and proteins to compete with each other. Three main competition systems have been described: type six secretion systems (T6SS); contact dependent inhibition (CDI); and bacteriocins. Unlike T6SS and CDI systems, bacteriocins do not require contact between bacteria but are diffusible toxins released into the environment. Identified almost a century ago, our understanding of bacteriocin distribution and prevalence in bacterial populations remains poor. In the case of protein bacteriocins, this is because of high levels of sequence diversity and difficulties in distinguishing their killing domains from those of other competition systems...

Cells that actively transcribe HIV-1 have been defined as the "active viral reservoir" in HIV-infected individuals. However, important technical limitations have precluded the characterization of this specific viral reservoir during both treated and untreated HIV-1 infections. Here, we used a novel single-cell RNA fluorescence in situ hybridization-flow cytometry (FISH-flow) assay that requires only 15 million unfractionated peripheral blood mononuclear cells (PBMCs) to characterize the specific cell subpopulations that transcribe HIV RNA in different subsets of CD4(+) T cells...

BACKGROUND: New, more effective and better-tolerated therapies for hepatitis C (HCV) have made the elimination of HCV a feasible objective. However, for this to be achieved, it is necessary to have a detailed understanding of HCV epidemiology in people who inject drugs (PWID). Respondent-driven sampling (RDS) can provide prevalence estimates in hidden populations such as PWID. The aims of this systematic review are to identify published studies that use RDS in PWID to measure the prevalence of HCV, and compare each study against the STROBE-RDS checklist to assess their sensitivity to the theoretical assumptions underlying RDS...

In an effort to axenically culture the previously uncultivable populations of the rhizobacteria of Lucerne (Medicago sativa L.), we propose plant-only teabags culture media to mimic the nutritional matrix available in the rhizosphere. Here, we show that culture media prepared from Lucerne powder teabags substantially increased the cultivability of Lucerne rhizobacteria compared with a standard nutrient agar, where we found that the cultivable populations significantly increased by up to 60% of the total bacterial numbers as estimated by Quantitative Real-time Polymerase Chain Reaction (qRT-PCR)...

Sponges are key organisms in the marine benthos where they play essential roles in ecological processes such as creating new niches, competition for resources, and organic matter recycling. Despite the increasing number of taxonomical studies, many sponge species remain hidden, whether unnoticed or cryptic. The occurrence of cryptic species may confound ecological studies by underestimating biodiversity. In this study, we monitored photographically growth, fusions, fissions, and survival of two morphologically cryptic species Hemimycale mediterranea Uriz, Garate & Agell, 2017 and H...

Although Arabs are a growing population in the United States, they are a hidden minority when compared to larger, more studied groups like Latinos and Caribbean immigrants of African descent (CIAD). There is limited research pertaining to patients' unmet socioeconomic and supportive care needs when undergoing breast cancer treatment, particularly among immigrants and migrants. This is a comparative study of a nested cohort of 36 Arabs, 145 Latinos and 128 CIAD breast cancer patients participating in the Integrated Cancer Care Access Network and their areas of needed assistance...

Real time, or quantitative, PCR typically starts from a very low concentration of initial DNA strands. During iterations the numbers increase, first essentially by doubling, later predominantly in a linear way. Observation of the number of DNA molecules in the experiment becomes possible only when it is substantially larger than initial numbers, and then possibly affected by the randomness in individual replication. Can the initial copy number still be determined? This is a classical problem and, indeed, a concrete special case of the general problem of determining the number of ancestors, mutants or invaders, of a population observed only later...

BACKGROUND: Cryptotia is a common congenital ear deformity in Asian populations. In cryptotia, a portion of the upper ear is hidden and fixed in a pocket of the skin of the mastoid. Here we describe our method for cryptotia correction by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap. PATIENTS AND METHODS: We developed a new method for correcting cryptotia by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap...

BACKGROUND: Cryptic genetic variation (CGV) is the hidden genetic variation that can be unlocked by perturbing normal conditions. CGV can drive the emergence of novel complex phenotypes through changes in gene expression. Although our theoretical understanding of CGV has thoroughly increased over the past decade, insight into polymorphic gene expression regulation underlying CGV is scarce. Here we investigated the transcriptional architecture of CGV in response to rapid temperature changes in the nematode Caenorhabditis elegans...

This case report describes a gastric acid burn. Gastric acid burns secondary to vomiting in an elderly patient who has fallen and experienced a so called "long lie" have not been reported. The patient was admitted under the physicians and referred to the burns team once the wounds were recognized as burns. The patient was treated nonsurgically with dressings and healed well with conservative treatment. Here, the authors highlight the importance of recognizing and treating burns of this nature in our ageing population...

Microbes drive ecosystems under constraints imposed by viruses. However, a lack of virus genome information hinders our ability to answer fundamental, biological questions concerning microbial communities. Here we apply single-virus genomics (SVGs) to assess whether portions of marine viral communities are missed by current techniques. The majority of the here-identified 44 viral single-amplified genomes (vSAGs) are more abundant in global ocean virome data sets than published metagenome-assembled viral genomes or isolates...

This study explored issues of culturally sensitive health care practice and needs among lesbian, gay, bisexual and transgender aging adults in coastal North Carolina. Survey data from 2013 to 2015 were analyzed using frequencies and logistic regression on concerns with culturally sensitive health needs for the LGBT aging adult population. Results indicated that the largest problem was a history of being verbally harassed (n = 115; 51.57%) and a need for more culturally sensitive health care provisions. A large majority of participants requested an improvement in offering of LGBT specific social activities (n = 149), recreational activities (n = 116), and art and cultural activities (n = 112)...
