A number of recent studies showed that digital footprints around built environments, such as geo-located tweets, are promising data sources for characterizing urban land use. However, challenges for achieving this purpose exist due to the volume and unstructured nature of geo-located social media. Previous studies focused on analyzing Twitter data collectively resulting in coarse resolution maps of urban land use. We argue that the complex spatial structure of a large collection of tweets, when viewed through the lens of individual-level human mobility patterns, can be simplified to a series of key locations for each user, which could be used to characterize urban land use at a higher spatial resolution...

INTRODUCTION: Trauma is a leading cause of morbidity and mortality worldwide. Data characterizing the burden of trauma in Cameroon is limited. Regular, prospective injury surveillance can address the shortcomings of existing hospital administrative logs and medical records. This study aims to characterize trauma as seen at the emergency department (ED) of Limbe Regional Hospital (LRH) and assess the completeness of data obtained by a trauma registry. METHODS AND FINDINGS: From January 2008 to October 2013, we prospectively captured data on injured patients using a strategically designed, context-relevant trauma registry instrument...

INTRODUCTION: "The hum" or "Taos hum" are common terms of a tinnitus with three remarkable features. OBJECTIVE: A possible common background is reevaluated for the three features of the hum: being sensitive on sound, head rotation, and long-distance air travel. MATERIALS AND METHODS: Questionnaires that were originally developed by Frosch were recalculated concerning the question of hum interactions with sounds. The question was split into the two affirmative answers a) "masking", which corresponds to the overrule of the hum by a sound, and b) "beats", which correspond to a nonlinear interaction with the hum as a Van der Pol-like oscillator...

Schistosomiasis remains one of the most prevalent parasitic diseases worldwide and the infection is frequently found in travelers and migrants. The European Network for Tropical Medicine and Travel Health conducted a sentinel surveillance study on imported schistosomiasis between 1997 and 2010. This report summarizes epidemiological and clinical data from 1,465 cases of imported schistosomiasis. Direct pathogen detection and serology were the main diagnostic tools applied. Of these, 486 (33%) cases were identified among European travelers, 231 (16%) among long-term expatriates, and 748 (51%) among non-European immigrants...

Every year Christian pilgrims from around the world visit the holy sites located around the Sea of Galilee. Some become ill during their stay with infectious diseases that were acquired in their country of origin, and are hospitalized at Poriya Medical Center. They pose a diagnostic challenge due to language barriers, the rarity of these infections in Israel, and the fact that diagnostic tests are not readily available. All patient records from 2015 of Holy Land tourists hospitalized at Poriya Medical Center were screened for the diagnosis of imported zoonotic diseases that are not commonly diagnosed in Israel...

Marine microorganisms such as Shewanella spp., Vibrio spp., and Aeromonas spp. can cause sepsis secondary to a wound infection in the context of swimming. These microorganisms are most often susceptible to fluoroquinolones. Here, we report a unique case of Shewanella algae bacteremia associated with meningoencephalitis and disseminated via hematogenous spread secondary to a skin injury. The patient suffered the injury while swimming in saline water during a cruise holiday in Madagascar, and she was initially treated with amoxicillin...

Key goal and targets of the Ethiopian national malaria control strategy are to achieve malaria elimination within specific geographical areas with historically low malaria transmission and to reach near-zero malaria transmission in the remaining malarious areas by 2020. However, back and forth population movement between high-transmission and low-transmission area imposes challenge on the success of national malaria control programs. Therefore, examining the effect of human movement and identification of at-risk populations is crucial in an elimination setting...

Jean-Pierre Olivier de Sardan, Aïssa Diarra, Mahaman Moha
As in other areas of international development, we are witnessing the proliferation of 'traveling models' developed by international experts and introduced in an almost identical format across numerous countries to improve some aspect of maternal health systems in low- and middle-income countries. These policies and protocols are based on 'miracle mechanisms' that have been taken out of their original context but are believed to be intrinsically effective in light of their operational devices.In reality, standardised interventions are, in Africa and elsewhere, confronted with pragmatic implementation contexts that are always varied and specific, and which lead to drifts, distortions, dismemberments and bypasses...

West Africa was the focus of global attention during the Ebola virus disease outbreak, when systemic health system weaknesses compounded a serious emergency and complicated response efforts. Following the crisis, calls were made to strengthen health systems, but investments to date have fallen short of delivering the support needed to build strong health systems able to prevent and manage future outbreaks.In part, this reality serves to highlight the shortcomings of the solutions being repeatedly prioritised by external funders and experts, solutions that often fail to consider the wealth of West African evidence and actors actively working to strengthen the leadership and health systems needed to drive and sustainably improve national health outcomes...

OBJECTIVE: Prophylaxis with granulocyte colony-stimulating factors (G-CSFs) is recommended for patients receiving myelosuppressive chemotherapy regimens with a high risk of febrile neutropenia (FN). G-CSFs should be administered starting the day after chemotherapy, necessitating return trips to the oncology clinic at the end of each cycle. We examined the travel burden related to prophylactic G-CSF injections after chemotherapy in the United States (US). METHODS: We used 2012-2014 Medicare claims data to identify a national cohort of beneficiaries age 65+ with non-myeloid cancers who received both chemotherapy and prophylactic G-CSFs...

Migratory waterfowl may play a role in the ecology and transmission of zoonotic pathogens, given their ability to travel long distances and their use of varied habitats. Our objectives were to estimate the prevalence of Salmonella among waterfowl along the Texas Gulf coast and to characterize the isolates. Faecal samples were collected from hunter-harvested waterfowl at four wildlife management areas from September through November, 2016. Standard bacteriologic culture methods were used to isolate Salmonella from samples, and isolates were characterized by serotyping and anti-microbial susceptibility testing...

BACKGROUND: The mammalian circadian clock and its associated clock genes are increasingly be recognized as critical components for a number of physiological and disease processes that extend beyond hormone release, thermal regulation, and sleep-wake cycles. New evidence suggests that clinical behavior disruptions that involve prolonged shift work and even space travel may negatively impact circadian rhythm and lead to multi-system disease. METHODS: In light of the significant role circadian rhythm can hold over the body's normal physiology as well as disease processes, we examined and discussed the impact circadian rhythm and clock genes hold over lifespan, neurodegenerative disorders, and tumorigenesis...

This paper discusses the life and scientific work of José Vicente Barbosa du Bocage (1823-1907), a nineteenth-century Portuguese naturalist who carved a new place for zoological research in Portugal and built up a prestigious scientific career by securing appropriate physical and institutional spaces to the discipline. Although he was appointed professor of zoology at the Lisbon Polytechnic School, an institution mainly devoted to the preparatory training of military officers and engineers, he succeeded in creating the conditions that allowed him to develop consistent research in zoology at this institution...

This is a case of strongyloidiasis showing colon enhancement on a computerized tomography (CT) scan. The patient presented with chief complaints of diarrhea and abdominal pain. She gave a history of recent travel to El Salvador and her stool was positive for Strongyloides stercoralis. A CT scan revealed a circumferential enhancement of the sigmoid colon. This CT sign was unusual in strongyloidiasis and when combined with the symptoms, caused us to rule out inflammatory bowel disease and shock bowel. Stool examination revealed ova and parasites of Strongyloides stercoralis...

A fly larva was recovered from a boil-like lesion on the left leg of a 33-year-old male on 21 November 2016. He has worked in an endemic area of myiasis, Uganda, for 8 months and returned to Korea on 11 November 2016. The larva was identified as Cordylobia anthropophaga by morphological features, including the body shape, size, anterior end, posterior spiracles, and pattern of spines on the body. Subsequent 28S rRNA gene sequencing showed 99.9% similarity (916/917 bp) with the partial 28S rRNA gene of C. anthropophaga...

This study quantified the effects of traffic restrictions on diesel fuel heavy vehicles (HVs) on the air quality of the Bandeirantes corridor using hourly data obtained by continuous monitoring of traffic and air quality at sites located on this avenue. The study addressed the air quality of a city impacted by vehicular emissions and that PM10 and NOX concentrations are mainly due to diesel burning. Data collection was split into two time periods, a period of no traffic constraint on HVs (Nov 2008 and 2009) and a period of constraint (Nov 2010, 2011 and 2012)...

Pain is the most feared symptom amongst individuals living with cancer. In 15% to 20% of patients, conventional analgesic therapy either fails to relieve pain or induces adverse effects. Intrathecal drug delivery systems may present an effective alternative for pain management. The Cancerology Center Paul Papin protocol includes an admixture of morphine, ropivacaine, and ziconotide in intrathecal preparations. These drugs are administered by a fully implantable or an external pump. Syringes or polyolefin infusion bags are prepared for refill just before use...
