Menstrual hygiene management among adolescent girls in West Africa: A systematic review.

A systematic literature review was conducted to examine all recent academic, peer-reviewed studies of menstrual hygiene management (MHM) across adolescent girls in Anglophone West Africa. The objective was to assess the status of the scholarship surrounding the knowledge, attitudes, and practices of MHM across English-speaking West African countries and identify gaps in the literature for further research. The authors searched the epidemiological literatures indexed in PubMed and cross-referenced bibliographies for studies published between 2010-2022. Of 59 abstracts and articles screened, 35 met the final inclusion criteria. Despite differences in study design, setting, and data sources, the study results concurred on an average age of menarche between 12-15 years old among adolescent girls. The knowledge of MHM came from multiple sources, most commonly mothers, female siblings, and teachers and higher knowledge was associated with age, source, wealth, religion, and education level. Less than half of the adolescent girls knew about menstruation before menarche. Many studies showed that girls were shocked by their first period and fearful of staining. Menstruation was associated with dysmenorrhea, fear/embarrassment, and missing school. The existing studies suggest that more implementation and evaluation of menstrual hygiene management materials, education, and facilities are needed to address the educational, physical, and social disparities that exist among girls in West African countries.

Une revue systématique de la littérature a été menée pour examiner toutes les études universitaires récentes évaluées par des pairs sur la gestion de l'hygiène menstruelle (MHM) chez les adolescentes d'Afrique de l'Ouest anglophone. L'objectif était d'évaluer l'état de la recherche sur les connaissances, les attitudes et les pratiques de la GHM dans les pays anglophones d'Afrique de l'Ouest et d'identifier les lacunes dans la littérature pour des recherches plus approfondies. Les auteurs ont recherché dans la littérature épidémiologique indexée dans PubMed et des bibliographies croisées pour les études publiées entre 2010 et 2022. Sur les 59 résumés et articles examinés, 35 répondaient aux critères d'inclusion finaux. Malgré les différences dans la conception, le cadre et les sources de données de l'étude, les résultats de l'étude concordaient sur un âge moyen des premières règles entre 12 et 15 ans chez les adolescentes. La connaissance de la GHM provenait de sources multiples, le plus souvent des mères, des frères et sœurs et des enseignants, et les connaissances supérieures étaient associées à l'âge, à la source, à la richesse, à la religion et au niveau d'éducation. Moins de la moitié des adolescentes connaissaient leurs règles avant les premières règles. De nombreuses études ont montré que les filles étaient choquées par leurs premières règles et craignaient les taches. Les menstruations étaient associées à la dysménorrhée, à la peur/à la gêne et à l'absence à l'école. Les études existantes suggèrent qu'une plus grande mise en œuvre et une plus grande évaluation du matériel, de l'éducation et des installations de gestion de l'hygiène menstruelle sont nécessaires pour remédier aux disparités éducatives, physiques et sociales qui existent parmi les filles dans les pays d'Afrique de l'Ouest.

Surgical treatment trends and outcomes for anal fistula: fistulotomy is still accurate and safe. Results from a nationwide observational study.

PURPOSE: The aim of the present study was to analyse current surgical treatment preferences for anal fistula (AF) and its subtypes and nationwide results in terms of success and complications. METHODS: A retrospective multicentre observational cohort study was conducted. The study period was 1 year (2019), with a follow-up period of at least 1 year. A descriptive analysis of patient characteristics and trends regarding technical options was performed. Univariate and multivariate Cox regression models were used to analyse factors associated with healing and faecal incontinence (FI). RESULTS: Fifty-one hospitals were involved, providing data on 1628 patients with AF. At a median follow-up of 18.3 (9.9-28.3) months, 1231 (75.9%) patients achieved healing, while 390 (24.1%) did not; failure was catalogued as persistence in 279 (17.2.0%) patients and as recurrence in 111 (6.8%). On multivariate analysis, factors associated with healing were fistulotomy (OR 5.5; 95% CI 3.8-7.9; p < 0.001), simple fistula (OR 2.1; 95% CI 1.5-2.8; p < 0.001), single tract (HR 1.9; 95% CI 1.3-2.8; p < 0.001) and number of preparatory surgeries (none vs. 3; HR 1.8; 95% CI 1.2-2.8; p = 0.006). Regarding de novo FI, in the multivariate analysis previous anal surgery (OR 1.5, 95% CI 1.0-2.4, p = 0.037), age (OR 1.02, 95% CI 1.00-1.04, p = 0.002) and being female (OR 1.7, 95% CI 1.1-2.5, p = 0.008) were statistically related. CONCLUSIONS: Anal fistulotomy is the most used procedure for AF, especially for simple AF, with a favourable overall balance between healing and continence impairment. Sphincter-sparing or minimally invasive sphincter-sparing techniques resulted in lower rates of healing. In spite of their intended sphincter-sparing design, a certain degree of FI was observed for several of these techniques.

Preclinical Evaluation of Trabectedin in Combination With Targeted Inhibitors for Treatment of Metastatic Uveal Melanoma.

Purpose: Uveal melanoma (UM) is considered a rare disease; yet, it is the most common intraocular malignancy in adults. Although the primary tumor may be efficiently managed, more than 50% of patients with UM develop distant metastases. The mortality at the first year after diagnosis of metastatic UM has been estimated at 81%, and the poor prognosis has not improved in the past years due to the lack of effective therapies. Methods: In order to search for novel therapeutic possibilities for metastatic UM, we performed a small-scale screen of targeted drug combinations. We verified the targets of the tested compounds by western blotting and PCR and clarified the mechanism of action of the selected combinations by caspase 3 and 7 activity assay and flow cytometry. The best two combinations were tested in a mouse patient-derived xenograft (PDX) UM model as putative therapeutics for metastatic UM. Results: Combinations of the multitarget drug trabectedin with either the CK2/CLK double-inhibitor CX-4945 (silmitasertib) or the c-MET/TAM (TYRO3, Axl, MERTK) receptor inhibitors foretinib and cabozantinib demonstrated synergistic effects and induced apoptosis (relative caspase 3 and 7 activity increased up to 20.5-fold in UM cell lines). In the case of the combination of foretinib and cabozantinib, inhibition of the TAM receptors, but not c-Met, was essential to inhibit the growth of UM cells. Monotreatment with trabectedin inhibited tumor growth by 42%, 49%, and 35% in the MM26, MM309, and MM339 PDX mouse models, respectively. Conclusions: Trabectedin alone or in combination with cabozantinib inhibited tumor growth in PDX UM mouse models. Blocking of MERTK, rather than TYRO3, activity inhibited UM cell growth and synergized with trabectedin.

Early colorectal cancer diagnosed after endoscopic resection: Conservative treatment is safe in most of the cases. Proposal for a risk-based management / Cáncer colorrectal inicial tras resección endoscópica: el tratamiento conservador es seguro en la mayoría de los casos. Propuesta de un manejo basado en los factores de riesgo

Introduction Endoscopic resection offers advantages over surgical resection for early colorectal cancer (ECC). However, there might be a presumed risk of recurrence. We aimed to determine the risk of recurrence after endoscopic removal of ECC. Methods A single-centre series of endoscopic resections for ECC. Patients were stratified according to four risk factors: positive resection margins, Haggitt 4, lymphatic/vascular invasion and tumour budding. Results We included 127 patients. Haggitt classification was grade 4 in 54.0%. Positive margins were found in 43 (33.9%), 16 (12.6%) had lymphatic or vascular invasion, and 5 (4.0%) had high grade budding. In 82 (64.5%) endoscopic excision was the definitive treatment, 45 (35.4%) underwent surgery. Six patients (13.3%) had residual tumour on specimen and/or node metastases. Postoperative complications occurred in ten (22.2%). At a median follow-up of 63 months, none of the 82 patients treated with endoscopic resection alone had recurrence. After stratifying patients according to risk factors, those who had residual tumour also had ≥2 risk factors. Conclusions Endoscopic follow up might be a valid option for patients with ECC. A risk-adjusted management seems prudent (AU)

Introducción La resección endoscópica ofrece claras ventajas frente a la cirugía en el tratamiento del cáncer de colon inicial (ECC). Sin embargo, existe un riesgo de recurrencia tanto a nivel del lecho de polipectomía como a nivel ganglionar. El objetivo del estudio es determinar el riesgo de recurrencia tras la resección endoscópica del ECC. Métodos Serie retrospectiva unicéntrica de resecciones endoscópicas de ECC. Se analizaron cuatro factores de riesgo en la pieza de polipectomía: el margen de resección afecto, Haggitt 4, invasión linfovascular y la presencia de budding tumoral. Resultados Se incluyeron 127 pacientes: Haggitt 4 en el 54%, margen de resección afecto en el 33,9%, infiltración linfática o vascular en el 12,6% y budding tumoral de alto grado en el 4%. En 82 pacientes (64,5%), la resección endoscópica fue el tratamiento definitivo. En 45 (35,4%) se realizó una colectomía oncológica. Seis pacientes (13,3%) presentaron tumor residual en el lecho de la polipectomía y/o a nivel de los ganglios linfáticos. La morbilidad postoperatoria fue del 22% y la mortalidad del 0%. Tras un seguimiento medio de 63 meses, ninguno de los 82 pacientes del grupo de polipectomía presentó recurrencia tumoral. Tras dividir a los pacientes según el número de factores de riesgo presentes, aquellos que presentaron tumor residual en la pieza de colectomía presentaban a su vez ≥ 2 factores de riesgo. Conclusiones El seguimiento endoscópico puede ser una opción válida en los pacientes con ECC. El manejo de estos pacientes debe ajustarse al riesgo individual, en función del número de factores de riesgo (AU)

Revisión bibliográfica de las actuaciones llevadas a cabo en materia de farmacogenética en farmacia comunitaria en distintos países / Bibliographic review of pharmacogenetic actions carried out in community pharmacy in different countries

JUSTIFICACIÓN: la farmacogenética se ha implementado principalmente para la dosificación de medicamentos en el ámbito hospitalario. Sin embargo, en los últimos 10 años ha tomado relevancia en el entorno de la farmacia comunitaria, especialmente en otros países europeos, EEUU y Canadá. Para plantear los futuros pasos a nivel nacional, se hace interesante conocer la situación en materia de investigación farmacogenética en farmacia comunitaria en estos países.OBJETIVO: conocer el tipo de estudios de investigación sobre farmacogenética en farmacia comunitaria desarrollados en distintos países.MATERIAL Y MÉTODOS: se realizó una revisión bibliográfica con el motor de búsqueda Pubmed, en la mayor base de datos de acceso libre de artículos científicos: Medline. Para encontrar los artículos de nuestro interés, es decir, que trataran de trabajos de investigación relacionados con la farmacogenética y que se hubieran llevado a cabo en farmacia comunitaria, se utilizaron los siguientes términos de búsqueda: pharmacogenetics; pharmacogenomics; community pharmacy; pilot study; service implementation; y testing. Las publicaciones identificadas se agruparon por temática relacionada en base a las similitudes metodológicas que presentaron.RESULTADOS: se identificaron 29 publicaciones relevantes para la revisión. De estas publicaciones, el 34,5 % se habían publicado entre los años 2020 y 2021. Además, el 65,5 % de ellas se basaban en trabajos realizados en farmacias comunitarias de EEUU y el 3,5 % en farmacias comunitarias españolas. Las temáticas de dichas publicaciones se agruparon de la siguiente forma: encuestas a farmacéuticos (37,9 %), ajustes de tratamientos guiados por test farmacogenéticos (34,5 %), entrevistas a pacientes (6,9 %), comparación de la implantación del servicio de farmacogenética y el servicio de farmacogenética junto con el manejo del tratamiento médico (6,9 %) y otros variados (13,8 %).

Evidencia farmacogenética disponible de los subgrupos terapéuticos más consumidos en España / Available pharmacogenetic evidence on the most widely used therapeutic subgroups in Spain

JUSTIFICACIÓN: la variabilidad interindividual en la respuesta a los medicamentos depende de muchos factores, entre los que se encuentra el perfil genético. Polimorfismos en los genes que codifican proteínas implicadas en la farmacocinética y farmacodinámica de los medicamentos pueden modificar su efecto, dando lugar a una respuesta pobre y por lo tanto un tratamiento inefectivo, o una respuesta exagerada lo que conlleva un riesgo alto de toxicidad. La presencia de polimorfismos en genes de transportadores, enzimas metabolizadoras o receptores podría implicar la necesidad o recomendación de un ajuste de dosis, sustitución y/o retirada de los medicamentos. Debido a esto, conocer qué evidencia existe en relación a la farmacogenética de los medicamentos de mayor consumo es de gran interés para los farmacéuticos comunitarios.OBJETIVO: identificar los medicamentos más consumidos en España y determinar la evidencia científica existente en cuanto al efecto que la farmacogenética tiene en ellos.MATERIAL Y MÉTODOS: se identificaron los 15 grupos de medicamentos más consumidos en España (clasificados por subgrupo terapéutico, ACT4) en base al último informe anual disponible de la Prestación Farmacéutica en el Sistema Nacional de Salud (2019).Para cada medicamento de dichos grupos se realizó una búsqueda de la evidencia científica disponible, en materia de farmacogenética, en las Guías Clínicas del CPIC y el DPWG y las anotaciones registradas en la base de datos sobre farmacogenética PharmGKB.RESULTADOS: los 15 subgrupos terapéuticos más dispensados en farmacia comunitaria en España en el 2019 sumaron el 48 % de todos los medicamentos dispensados. De ellos, 8 subgrupos disponen de guías clínicas publicadas de dosificación basada en farmacogenética (Antiulcerosos: inhibidores de la bomba de protones; Hipolipemiantes: inhibidores de la HMG CoA reductasa; Inhibidores de la agregación plaquetaria, excluyendo heparina.

Longitudinal Single Photon Emission Computed Tomography Neuroimaging as an Indication of Improvement in Psychiatric Disorders in a Community Psychiatric Practice.

In the community, there is a need to more objectively evaluate the response of common chronic psychiatric disorders to treatment. Brain single photon emission computed tomography (SPECT) indirectly measures cerebral functional activity by uptake of a radiotracer, which follows regional cerebral blood flow. Brain 3D Thresholded SPECT scans are thresholded three dimensional images derived from brain SPECT data. A retrospective community study of longitudinal (before and after treatment) brain 3D Thresholded SPECT scans of 73 patients with all-cause psychiatric disorders (most frequent diagnostic clusters: attention-deficit hyperactivity disorder, post-mild traumatic brain injury, affective disorders, psychotic disorders, post-viral chronic syndromes), shows these baseline SPECT scans predict improvement (non-worsening to large improvement) in clinical functioning with a sensitivity of 94% (95% confidence interval 86-98%) and a specificity of 67% (95% confidence interval 21-94%). In contrast, contemporaneous analysis by the same radiologist of conventional 2D reading of the same before and after treatment brain SPECT scan data of the same 73 patients, predicted improvement (non-worsening to large improvement) in clinical functioning with a sensitivity of only 26% (95% confidence interval 17-37%) although with a specificity of 100% (95% confidence interval 44-100%). These data suggest 3D Thresholded SPECT scans can provide the clinician with a more objective measure for verifying improvement in psychiatric disorders seen in the community, consistent with prior studies of SPECT as a measure of neurobiological change. Furthermore, these data suggest 3D Thresholded SPECT scans may have clinical application in guiding treatment and potentially improving outcomes.

Circulation of zoonotic flaviviruses in wild passerine birds in Western Spain.

We explore the presence of zoonotic flaviviruses (West Nile virus (WNV) and Usutu virus (USUV)) neutralizing antibodies in rarely studied passerine bird species. We report, for the first time in Europe, WNV-specific antibodies in red avadavat and cetti's warbler, and USUV in yellow-crowned bishop. The evidence of WNV and USUV circulating in resident and migratory species has implications for both animal and public health. Future outbreaks in avian reservoir hosts may occur and passerines should be considered as priority target species in flavivirus surveillance programmes.

Capsular release following total shoulder arthroplasty: an analysis of early outcomes.

BACKGROUND: The purpose of this study is to analyze the outcomes of open and arthroscopic capsular release following total shoulder arthroplasty. METHODS: Over 15 years, 19 patients experienced persistent shoulder stiffness after anatomic total shoulder arthroplasty refractory to nonoperative treatment, requiring either open (n = 5) or arthroscopic (n = 14) capsular release. There were seven (39%) patients who had a prior diagnosis of stiffness before the primary arthroplasty. RESULTS: At a follow-up of 2.3 years (1-5.5), there were changes in range of motion, including forward flexion (77°-117°), abduction (49°-98°), external rotation (9°-19°), internal rotation at 0° (Sacrum to L1), and pain (4.1-2.3) scores (p < 0.01). There were seven (37%) patients that required a reoperation following the initial capsular release. The survival-free of reoperation at 2 and 5 years was 76% and 53%, respectively, while the survival-free of revision surgery at 2 and 5 years was 83%. Furthermore, three (16%) patients required a repeat capsular release. Overall, there were 11 (58%) complications, including stiffness (n = 9), infection (n = 1), subscapularis rupture (n = 2), glenoid loosening (n = 3), and pain with weakness requiring reoperation (n = 1). CONCLUSIONS: Shoulder stiffness after total shoulder arthroplasty is a very difficult pathology to treat, with high rates of complications and reoperations after capsular release. Overall, in patients that do not develop glenoid loosening, capsular release does improve the patient's pain and shoulder motion. Furthermore, when patients develop stiffness, it is critical to rule out other etiologies, such as glenoid loosening, prior to proceeding with capsular release. LEVEL OF EVIDENCE IV: Retrospective case series.

Determinants of the current and future distribution of the West Nile virus mosquito vector Culex pipiens in Spain.

Changes in environmental conditions, whether related or not to human activities, are continuously modifying the geographic distribution of vectors, which in turn affects the dynamics and distribution of vector-borne infectious diseases. Determining the main ecological drivers of vector distribution and how predicted changes in these drivers may alter their future distributions is therefore of major importance. However, the drivers of vector populations are largely specific to each vector species and region. Here, we identify the most important human-activity-related and bioclimatic predictors affecting the current distribution and habitat suitability of the mosquito Culex pipiens and potential future changes in its distribution in Spain. We determined the niche of occurrence (NOO) of the species, which considers only those areas lying within the range of suitable environmental conditions using presence data. Although almost ubiquitous, the distribution of Cx. pipiens is mostly explained by elevation and the degree of urbanization but also, to a lesser extent, by mean temperatures during the wettest season and temperature seasonality. The combination of these predictors highlights the existence of a heterogeneous pattern of habitat suitability, with most suitable areas located in the southern and northeastern coastal areas of Spain, and unsuitable areas located at higher altitude and in colder regions. Future climatic predictions indicate a net decrease in distribution of up to 29.55%, probably due to warming and greater temperature oscillations. Despite these predicted changes in vector distribution, their effects on the incidence of infectious diseases are, however, difficult to forecast since different processes such as local adaptation to temperature, vector-pathogen interactions, and human-derived changes in landscape may play important roles in shaping the future dynamics of pathogen transmission.

Ergonomic assessment of a new hand tool design for laparoscopic surgery based on surgeons' muscular activity.

Laparoscopic surgery techniques are customarily used in non-invasive procedures. That said traditional surgical instruments and devices used by surgeons suffer from certain ergonomic deficiencies that may lead to physical complaints in upper limbs and back and general discomfort that may, in turn, affect the surgeon's skills during surgery. A novel design of the laparoscopic gripper handle is presented and compared with one of the most used instruments in this field in an attempt to overcome this problem. The assessment of the ergonomic feature of the novel design was performed by using time-frequency analysis of the surface electromyography (sEMG) signal during dynamic activities. Singular Spectrum Analysis (SSA) was used to decompose the sEMG signal and extract the median frequency of each muscle to assess muscle fatigue. The results reveal that using the proposed ergonomic grip reduces the mean values of the muscle activity during each of the proposed tasks. The novel design also improves the ease of use in laparoscopic surgery as it minimises high-pressure contact areas, reduces large amplitude movements and promotes a neutral position of the hand, wrist and forearm. Furthermore, the SSA method for time-frequency analysis provides a powerful tool to analyse a prescribed activity in ergonomic terms. The proposed methodology to assess muscle activity during surgery activities may be useful in the selection of surgical instruments when programming extended procedures, as it provides an additional selection criterion based on the surgeon's biomechanics and the proposed activity.

Biological mesh reconstruction versus primary closure for preventing perineal morbidity after extralevator abdominoperineal excision: a multicentre retrospective study.

AIM: The aim of the study was to compare the incidence of perineal hernia and the perineal wound morbidity following extralevator abdominoperineal excision (ELAPE) between two groups - primary perineal closure and reconstruction with a biological mesh. METHOD: One hundred and forty-seven consecutive patients who underwent ELAPE for primary rectal cancer between January 2007 and December 2018 in two tertiary referral centres were retrospectively identified from prospective databases. Perineal closure was carried out via primary closure or with a biological mesh (porcine dermal collagen mesh). Outcome measures were perineal hernia and perineal wound morbidity (infection, dehiscence, persistent sinus and chronic pain). RESULTS: A total of 139 patients were included in the study. A prophylactic mesh was used in 80 (57.5%) and primary closure was practised in 59 (42.4%) patients. The median follow-up was 30 (interquartile range 46.88) months. Thirty patients (21.6%) developed perineal hernia. No significant differences were found between prophylactic mesh and primary closure (16.3% vs 23.3%, P = 0.07). The median period between surgery and hernia diagnosis was 8 months in the primary closure group and 24 months in the mesh group (P < 0.01). Perineal wound morbidity was significantly higher in the prophylactic mesh group (55% vs 33.9%, P < 0.01). CONCLUSION: In our study, the use of a biological mesh did not reduce the rate of perineal hernia, although it did delay its appearance. Perineal closure using a biological mesh may increase perineal morbidity, both acute and chronic.

Functional Neuroimaging in Psychiatry-Aiding in Diagnosis and Guiding Treatment. What the American Psychiatric Association Does Not Know.

While early efforts in psychiatry were focused on uncovering the neurobiological basis of psychiatric symptoms, they made little progress due to limited ability to observe the living brain. Today, we know a great deal about the workings of the brain; yet, none of this neurobiological awareness has translated into the practice of psychiatry. The categorical system which dominates psychiatric diagnosis and thinking fails to match up to the real world of genetics, sophisticated psychological testing, and neuroimaging. Nevertheless, the American Psychiatric Association (APA) recently published a position paper stating that neuroimaging provided no benefit to the diagnosis and treatment of psychiatric disorders. Using the diagnosis of depression as a model, we illustrate how setting aside the unrealistic expectation of a pathognomonic "fingerprint" for categorical diagnoses, we can avoid missing the biological and, therefore, treatable contributors to psychopathology which can and are visualized using functional neuroimaging. Infection, toxicity, inflammation, gut-brain dysregulation, and traumatic brain injury can all induce psychiatric manifestations which masquerade as depression and other psychiatric disorders. We review these and provide illustrative clinical examples. We further describe situations for which single photon emission computed tomography (SPECT) and positron emission tomography (PET) functional neuroimaging already meet or exceed the criteria set forth by the APA to define a neuroimaging biomarker, including the differential diagnosis of Alzheimer's disease and other dementias, the differential diagnosis of ADHD, and the evaluation of traumatic brain injury. The limitations, both real and perceived, of SPECT and PET functional neuroimaging in the field of psychiatry are also elaborated. An important overarching concept for diagnostic imaging in all its forms, including functional neuroimaging, is that imaging allows a clinician to eliminate possibilities, narrow the differential diagnosis, and tailor the treatment plan. This progression is central to any medical diagnostic process.

Evolution and associated factors of hand hygiene compliance in a pediatric tertiary hospital.

BACKGROUND: The objective is to know the evolution of the Degree of Compliance with Recommendations (DCR) on hand hygiene (HH) and its associated factors in the pediatric care areas (PCAs) of a tertiary hospital. METHODS: Observational, cross-sectional study, repeated over time, with direct observation of the DCR on HH during the daily activity of health care workers. Over 13 years, 9226 HH opportunities were observed. Associations between DCR, PCA and other variables (eg, age, sex, and professional position) were examined using χ² and adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: DCR on HH in 9 PCAs was 64.3% (95% CI, 63.3-65.3), and in the group of non-pediatric areas it was 49.6% (95% CI, 49.1-50.1). The areas with the highest degree of compliance were Oncology 72.8% (95% CI, 69.2-76.4), Neonatology 73.2% (95% CI, 71.3-75.1), and Neonatal intensive care unit 70.0% (95% CI, 67.5-72.6). These were the areas with the strongest association with HH compliance, with aOR:2.8 (95% CI, 2.2-3.6); aOR, 3.0 (95% CI, 2.6-3.6) aOR:2.6 (95% CI, 2.1-3.1), respectively. Other associated factors were the indications "after an activity," aOR, 1.6 (95% CI, 1.5-1.8) and the availability of pocket-size alcohol-based solution, aOR, 2.1(95% CI, 1.9-2.3). CONCLUSIONS: The DCR on HH in PCAs is higher than in other areas, although there is still margin for improvement. We have identified modifiable factors that have an independent association with HH compliance in PCAs. Focusing on modifiable factors will increase compliance with HH with the ultimate goal of reducing healthcare associated infections.

Effect of a theory-based hand hygiene educational intervention for enhancing behavioural outcomes in Ghanaian schools: a cluster-randomised controlled trial.

OBJECTIVES: The study sought to determine whether a hand hygiene educational intervention underpinned by educational and psychosocial theories is effective in enhancing behavioural intention and proper handwashing practices among school children. METHODS: The study was a cluster-randomised controlled trial, with schools constituting the clusters. At baseline, 717 pupils organised in four clusters were recruited. Techniques for data collection included a structured observation. The Student's t test was used for data analysis. RESULTS: At follow-up, a statistically significant difference was observed between the study arms with regard to intention to wash hands with soap [after toilet use (p = 0.032, d = 0.5); before meals (p = 0.020, d = 0.2)]. Similarly, a statistically significant difference was identified between the study arms with regard to the practice of handwashing with soap (HWWS) [after toilet use (p = 0.005); before meals (p = 0.012)]. CONCLUSIONS: A theory-driven hand hygiene educational intervention involving school children can have a medium to a very large effect size, with respect to the practice of HWWS, and a low to a medium effect size with respect to behavioural intention.

Design of Semirigid Wearable Devices Based on Skin Strain Analysis.

Nowadays, both usability and comfort play a key role in the development of medical and wearable products. When designing any device that is in contact with the human body, the mechanical behavior of the embraced soft tissue must be known. The unavoidable displacement of the soft tissue during motion may lead to discomfort and, thus, the removal of the wearable product. This paper presents a new methodology to design and test a wearable device based on the measurement of the dynamic skin strain field. Furthermore, from this field, the anatomical lines with minimum strain (lines of nonextension (LoNEs)) are calculated to design the structural parts of the wearable device. With this new criterion, the resulting product is not only optimized to reduce the friction in skin-device interface, but fully personalized to the patient's morphology and motion. The methodology is applied to the design of an ankle-foot wearable orthosis for subjects with ankle dorsiflexors muscles weakness due to nervous system disorders. The results confirm that the use of LoNEs may benefit the design of products with a high interaction with the skin.

The impact of the reverse prosthesis on revision shoulder arthroplasty: analysis of a high-volume shoulder practice.

BACKGROUND: Since the approval of reverse shoulder arthroplasty (RSA) in 2004, the use of shoulder arthroplasty increased dramatically. Although the success of RSA in the revision setting has been demonstrated, there remains a paucity of studies examining the epidemiology of RSA in revision arthroplasty. This study describes trends of revision arthroplasty during the "era of the reverse," from 2005 through 2016. METHODS: In a multicenter retrospective analysis, we analyzed 274 revision shoulder arthroplasties converted to a RSA (n = 182), anatomic total shoulder arthroplasty (TSA, n = 68), or hemiarthroplasty (n = 24) from 2005 to 2016. Demographics, surgical indications, and types of prosthesis were analyzed. RESULTS: The number of revision arthroplasties increased over 12 years. From 2005 to 2010, TSA (33%) or hemiarthroplasty (16%) were used in similar rates as RSA (51%). From 2011 to 2016, there was a much higher incidence of revision arthroplasty with RSA (78%) compared with TSA (19%) or hemiarthroplasty (3%). Specifically, the number of RSAs increased in 2011 to 2016 compared with 2005 to 2010 in patients aged younger than 60 years, obese patients, patients with indications of glenoid loosening, and those with a diagnosis of diabetes mellitus or rheumatoid arthritis. CONCLUSIONS: The use of RSA for revision arthroplasty increased over the "era of the reverse" and became the majority by 2016. The reverse prosthesis has had expanding indications regarding both patient demographics and pathology. This study demonstrates the reverse prosthesis has had a similar and even more profound effect on revision shoulder arthroplasty than what has previously been well documented in the primary setting.
