"If I chose to listen to people, I possibly wouldn't be using family planning": Impact of external influences on women's contraceptive autonomy in rural Northwest Tanzania.

BACKGROUND: There is an increasing emphasis on promoting women's autonomy in reproductive decision-making, particularly given global efforts to increase contraceptive access and uptake. Scales to quantify autonomy have inconsistently included the effect of external influences and focused primarily on influences of partners. OBJECTIVES: This study aimed to gain greater depth in understanding how influences including and beyond a woman's partner affect her contraceptive decision-making, as well as how external influences can overlap and further complicate contraceptive decision-making. DESIGN: A phenomenological, qualitative study in which in-depth interviews were conducted in three phases from May 2021 to February 2022 with women living in northwest Tanzania who had varying histories of contraceptive use or non-use. METHODS: One-on-one, in-depth interviews were conducted in Swahili, the national language of Tanzania, by trained female interviewers. Interviews were digitally recorded, transcribed, translated into English, and independently coded by three investigators. Analysis was conducted using NVivo. The codes developed from the transcripts were grouped into overarching themes with supporting illustrative quotes. RESULTS: A total of 72 women were interviewed. Partners were the most influential in women's family planning decision-making, followed by friends, relatives, community religious leaders, and healthcare providers. Out of the 52 women with a partner who had ever used family planning, 76.9% had discussed their desire to use family planning with their partner and nearly all reported strong pressures to use or not to use family planning from partners, family, and friends. Rarely, participants stated that they were devoid of any influence. CONCLUSION: In rural Tanzania, women's decision-making about family planning was highly impacted by external influences, including not only partners but also family, friends, and community. Indicators of women's reproductive autonomy and measurements of interventions to promote contraceptive use should incorporate measures of these external influences.

Reamputation prevalence after minor feet amputations in patients with diabetic foot, a cross sectional study. / Prevalencia de reamputación en amputaciones menores del pie en pacientes con pie diabético, estudio de corte transversal.

INTRODUCTION: Reported prevalence for reamputation in diabetic foot is diverse, risk factors are not clear for minor amputations. This study aims to determine the prevalence for reamputation in diabetic foot from minor amputations and to evaluate associated factors for such outcome. METHODS: Cross sectional study developed in 2hospitals. Patients hospitalized for diabetic foot ulcer requiring a minor amputation were included. A descriptive analysis of all variables is presented, as well as prevalence ratios (PR) and a multivariate logistic regression. RESULTS: The prevalence was of 48% for 15 years. Toes were the most frequent minor amputation that required reamputation and above the knee amputation was the most frequent reamputation level (45%). Variables whose PR was associated to reamputation risk were: smoking history (PR 1.32, CI 95%: 1.02-1.67, P=0.03), vascular occlusion in doppler (PR 1.47, CI 95%: 1.11-1.73, P=0.01), revascularization (PR 1.73, CI 95%: 1.31-2.14, P=0.00002), Wagner> 3 (PR 1.75, CI 95%: 1.16-1.84, P=0.01) and leucocytosis> 11,000 (PR 1.39, CI 95%: 1.07-1.68, P=0.01). Leucocytosis> 11,000, Wagner> 3, vascular occlusion in doppler and revascularization were the variables that best predicted the outcome. Furthermore, leucocytosis was the best variable for predicting reamputation (OR 2.4, CI 95%: 1.1-5.6, P=0.04). CONCLUSIONS: Reamputation prevalence was 48%. The toes were the minor amputation more frequently requiring reamputation and above the knee was the most frequent reamputation level. Risk for reamputation was associated with variables related to vascular compromise and infection.

On-site testing and treatment of sexually transmitted infections among female sex workers using molecular point-of-care testing integrated into harm reduction services in Madrid, Spain.

INTRODUCTION: This study aimed to evaluate the feasibility of molecular point-of-care testing for STIs, the prevalence of STIs and associated factors, and testing and treatment uptake among street-based female sex workers (FSWs) attending a mobile harm reduction unit in Madrid, Spain. METHODS: This was a prospective, longitudinal study. From August 15th to December 6th, 2022, participants were screened for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis using molecular testing (Xpert) on self-collected urine samples at a mobile harm reduction unit. Additionally, rapid tests were used to screen participants for HIV, hepatitis C virus (HCV), and syphilis. On-site same-day results and treatment for those infected were offered. RESULTS: Among 77 FSWs included the median age was 40 (range, 33-48), 64 % were homeless, and 84 % reported drug use in the past six months. Four participants self-reported having HIV, of whom all were on antiretroviral therapy, and 14 (18 %) had HCV antibodies, including three with current infection. The prevalence of at least one STI was 66 %. When categorized by type of STI, the prevalences were as follows: 15 % for CT, 15 % for NG, 51 % for TV, and 21 % for syphilis. Notably, the prevalence of STIs was higher among FSW with recent drug use, with no cases of CT or NG detected among FSWs who did not recently use drugs. In adjusted analysis, drug use was associated an increased odds of having an STI (adjusted odds ratio, 10.47; 95 % CI: 1.67-65.42). All participants consented to screening, and all but one received on-site result-based linkage to treatment. CONCLUSIONS: This study demonstrates the feasibility, high STI prevalence, and high linkage to testing and treatment following point-of-care molecular testing among street-based FSWs who have recently used drugs in Madrid, Spain.

Percutaneous cementoplasty of periprosthetic aseptic hip loosening.

Progressive population aging and improved healthcare have led to a significant increase in patients with hip arthroplasty (HA). In this patient group, the proportion of those who require a new arthroplasty (prosthetic replacement or secondary revision of the hip), has also increased. For this subgroup of patients in whom surgical prosthetic replacement should be considered but is contraindicated, a new technique has been developed since 2010: percutaneous injection of periprosthetic cement under fluoroscopic or CT control ("femoroplasty; FMP") as an alternative and less invasive treatment compared to surgery to stabilize the HA without replacing it, with excellent results on patients' quality of life. In this brief communication, we describe our positive experience regarding FMP, which we have performed for the first time in Spain on four patients (age range between 74-83 years, 2 female and 2 male patients, 3 right HA and 1 left HA), without post-complications. We highlight both the relative simplicity of this technique, which can be incorporated into radiological intervention even in regional hospitals, and the significant clinical improvement observed in all patients. In conclusion, we hope that our experience can contribute to the increased adoption of this innovative technique within the scientific community.

Partnerships with religious leaders to promote family planning in rural Tanzania: an open-label, cluster randomised trial.

BACKGROUND: Family planning benefits maternal-child health, education, and economic wellbeing. Despite global efforts, an unsatisfied demand for family planning persists in sub-Saharan Africa. Based on previous successful partnerships, the aim of this study was to determine whether an educational intervention for religious leaders would increase community knowledge, demand for, and ultimately uptake of family planning. METHODS: In this open-label, cluster randomised trial in Tanzania, 24 communities were randomised (1:1) to intervention or control arm. Communities, defined as the catchment area of a single public health facility, were eligible if they were at least 15 km from Mwanza City and had not previously participated in a health intervention for religious leaders. Random allocations were determined by coin toss and were not revealed to clinicians at health facilities in intervention and control communities, nor to the data entry team; however, due to the nature of the intervention, masking of religious leaders in the intervention communities was not possible. All Christian religious institutions were invited to send four leaders to an educational intervention that incorporated cultural, theological, and medical teaching about family planning. The primary outcome was contraceptive uptake at the community health facility during the year post intervention versus the year before the intervention. This trial was registered at clinicaltrials.gov, NCT03594305. FINDINGS: 75 communities in three districts were assessed for eligibility. 19 communities were excluded and 56 were eligible for study inclusion and were placed in random order to be invited to participate. The first 24 communities that were invited agreed to participate and were randomly assigned to receive the educational intervention either during the trial or after trial completion. Between July 10, 2018 and Dec 11, 2021, we provided the intervention in 12 communities and compared contraceptive uptake with 12 control communities. All were followed up for 12 months. In intervention communities, contraceptive uptake increased by a factor of 1·47 (95% CI 1·41-1·53) in the post-intervention (prospective) versus pre-intervention (historical) year (geometric mean of contraceptive uptake, 466 in the prospective year vs 312 in the historical year), versus 1·24 (95% CI 1·20-1·29) in control communities (geometric mean, 521 in the prospective year vs 429 in the historical year). The rate of change in contraceptive uptake was greater in intervention communities (between-group ratio of geometric mean ratios over time, 1·19 [95% CI 1·12-1·25]; p<0·0001). The COVID-19 pandemic was associated with decreased contraceptive uptake (geometric mean, 365 during the pandemic in communities that had the majority of their prospective 12-month data collection periods occur after March 16, 2020, vs 494 before the pandemic; geometric mean ratio, 0·72 [95% CI 0·57-0·90]; p=0·0040). INTERPRETATION: This intervention offers a scalable model, leveraging influence of trusted religious leaders to increase knowledge and uptake of family planning. New strategies such as this could help to overcome setbacks that occurred during the COVID-19 pandemic.

Development of an Inertial Measurement Unit (IMU) with datalogger and geopositioning for mapping the Earth's magnetic field.

The Earth's magnetic field is used in various navigation systems, but this field has a dynamic behavior that can be affected by different physical factors in local environments. These factors can pose risks to navigation systems and at the same time be a signal of a phenomenon that needs to be investigated, such as mineral concentration or the presence of interference from electrical equipment, among others. For that reason, in this project, this system was designed and integrated using a low-cost, military-grade magnet inductive magnetometer, which is integrated into two Inertial Measurement Units to corroborate the movement data, and at the same time a geopositioning system to georeference the sensor measurements. The information is managed by an MCU, which also stores data on an SD card. The system includes a lithium battery management system to provide more than an hour of autonomy. Wireless communication systems are intentionally avoided to prevent interference, and an infrared transmission LED is included instead, in case the real-time transmission is necessary. The results show that the proposed system allows for obtaining maps of magnetic field intensity in open spaces, and this information can be used to determine regions with anomalies.

Low-cost air, noise, and light pollution measuring station with wireless communication and tinyML.

Different types of environmental pollution cause negative consequences to ecosystems throughout the globe, which humanity is now trying to mitigate. It is necessary to know the level of pollution problems in the immediate environment, to evaluate the impact of human activities, and mitigation strategies necessary to ensure habitability. For this reason, in this work, a low-cost pollution measurement station for outdoor or indoor use is proposed and developed that measures air pollution (particulate matter and CO2), noise (level and direction), light pollution (power and multispectral), and also relative humidity and ambient temperature. The system stores the data in an SD memory or transmits data in real-time to the internet via WiFi. The purposes of the system are to be used in environmental studies, to deploy monitoring networks, or to ensure the habitability of a living or working space. The prototype integrates the measurement of the different sources of contamination in a single compact device at USD$ 628.12 without sacrificing measurement accuracy. The system is validated for each variable with reference equipment, obtaining an average error of approximately 2.67% in the measurement of all the variables measured. The system is easy to assemble and has an option for power supply using solar photovoltaic devices and an alternative for connection to 2G/3G mobile networks.

Neurosyphilis in a young man having HIV infection, blurring of vision and skin rash.

We report a 22-year-old homosexual man, a known case of HIV-1 infection but non-compliant to medications, who presented with a 5-month history of progressive painless non-pruritic coin-shaped skin lesions and recent gradual bilateral blurring of vision. His history divulged a primary syphilitic event 1 year prior to the present clinical manifestations. Investigation led to the diagnosis of neurosyphilis with ocular involvement with concurrent signs of secondary syphilis. Treatment with aqueous crystalline penicillin G, ophthalmic steroid and tropicamide drops, and topical emollients resulted in significant clinical improvement of ocular symptoms and skin lesions. The diagnosis of neurosyphilis requires a high degree of clinical suspicion and should be included in the differential diagnosis of unexplained ocular symptoms, particularly in men who have sex with men and HIV-infected patients. This is necessary for the early diagnosis, appropriate management, and good outcome of these patients.

Assessment of cerebral blood flow velocities, brain midline shift and optic nerve sheath diameter by ultrasound in patients undergoing elective craniotomy: A prospective observational feasibility study.

BACKGROUND: Brain ultrasound allows measuring the cerebral flow velocity, brain midline shift and optic nerve sheath diameter. Literature is scarce in determining the feasibility to perioperatively perform these measurements altogether and the cerebrovascular behavior in patients scheduled for elective craniotomy. METHODS: We assessed bilateral cerebral flow velocities, composite index, brain midline shift and optic nerve sheath diameter by cerebral ultrasound in patients scheduled for elective craniotomy before anesthetic induction, at extubation, and at 6 and 24 h after. The aim was to assess the feasibility of brain ultrasound in patients for elective craniotomy and to describe the changes in cerebral flow velocities, brain midline shift and optic nerve sheath diameter from baseline values at different times in the postoperative period. RESULTS: Sixteen patients were included, of these two were excluded from analysis due to an inadequate sonographic window. There were no changes throughout the study regarding cerebral flow velocity, brain midline shift nor optic nerve sheath diameter assessments. All parameters were maintained in the physiological range without significant variations during the procedure. No perioperative complications were detected. CONCLUSIONS: The results of our study show the feasibility to perform a perioperative assessment of cerebral flow velocity, brain midline shift or optic nerve sheath diameter jointly and successfully to obtain additional information of baseline cerebral hemodynamics in patients scheduled for elective craniotomy and their postoperative changes during the first 24 h. Future studies with lager samples are needed to address the efficacy of cerebral ultrasound as a monitoring tool.

Medición de las velocidades de flujo sanguíneo cerebral, desviación de la línea media y diámetro de la vaina del nervio óptico mediante ecografía en pacientes sometidos a craneotomía electiva: Estudio observacional prospectivo / Assessment of cerebral blood flow velocities, brain midline shift and optic nerve sheath diameter by ultrasound in patients undergoing elective craniotomy: A prospective observational feasibility study

Introducción: La ecografía cerebral permite valorar las velocidades del flujo sanguíneo cerebral (VFSC), la desviación de la línea media (DLM) y el diámetro de la vaina del nervio óptico (DVNO). La literatura es escasa en determinar la viabilidad de realizar dichas medidas, de forma conjunta en el perioperatorio, en pacientes programados para craneotomía electiva. Métodos: Evaluamos las VFSC de forma bilateral con sus índices compuestos, la DLM y el DVNO por medio de ultrasonido cerebral en pacientes programados para craneotomía electiva antes de la inducción anestésica, en la extubación inmediata, a las seis y 24 horas posoperatorias. El objetivo fue evaluar la viabilidad del uso de la ecografía cerebral en pacientes sometidos a craneotomía electiva y describir los cambios de estas mediciones en diferentes momentos con respecto a los valores basales. Resultados: Fueron incluidos 16 pacientes en el estudio, de los cuales dos se excluyeron del análisis debido a una mala ventana ecográfica. No hubo cambios a lo largo del estudio con respecto a las VFSC, tampoco en la DLM o en el DVNO. Todos los parámetros se mantuvieron dentro de los rangos fisiológicos sin variaciones significativas durante el procedimiento. No hubo complicaciones perioperatorias. Conclusiones: Los resultados de nuestro trabajo muestran la factibilidad de realizar una valoración perioperatoria de las VFSC, DLM y DVNO de forma conjunta y exitosa para obtener información de la hemodinámica cerebral basal en pacientes programados para craneotomía electiva y valorar sus cambios durante las primeras 24 horas del posoperatorio. Son necesarios estudios con mayor número de pacientes para evaluar la eficacia del ultrasonido cerebral como herramienta de monitorización neurológica perioperatoria.(AU)

Outdoor and synthetic performance data for PV devices concerning the weather conditions and capacitor values of I-V tracer.

This article presents the outdoor and synthetic performance data concerning the main electrical parameters estimated from the I-V curve for three photovoltaic technologies (HIT, m-Si and CIGS) and the weather conditions (irradiance, ambient and panel temperature). Synthetic data were generated by simulating in OpenModelica software the impact of weather conditions on device performance, considering an irradiance range between 50 and 1300 W/m2. The outdoor data corresponds to the performance of the evaluated PV modules in outdoor tests in Medellin-Colombia for ten months using capacitive I-V tracers. In both cases, different capacitor values were considered to evaluate the effect on the I-V curve behavior of devices.

The cumulant Green's functions method for the Hubbard model.

We use the cumulant Green's functions method (CGFM) to study the single-band Hubbard model. The starting point of the method is to diagonalize a cluster ('seed') containingNcorrelated sites and employ the cumulants calculated from the cluster solution to obtain the full Green's functions for the lattice. All calculations are done directly; no variational or self-consistent process is needed. We benchmark the one-dimensional results for the gap, the double occupancy, and the ground-state energy as functions of the electronic correlation at half-filling and the occupation numbers as functions of the chemical potential obtained from the CGFM against the corresponding results of the thermodynamic Bethe ansatz and the quantum transfer matrix methods. The particle-hole symmetry of the density of states is fulfilled, and the gap, occupation numbers, and ground-state energy tend systematically to the known results as the cluster size increases. We include a straightforward application of the CGFM to simulate the singles occupation of an optical lattice experiment with lithium-6 atoms in an eight-site Fermi-Hubbard chain near half-filling. The method can be applied to any parameter space for one, two, or three-dimensional Hubbard Hamiltonians and extended to other strongly correlated models, like the Anderson Hamiltonian, thet - J, Kondo, and Coqblin-Schrieffer models.

Low-cost system for analysis pedestrian flow from an aerial view using Near-Infrared, Microwave, and Temperature sensors.

The use of IoT systems that support the construction of smart cities is a global trend that directly affects the quality of life of citizens. for vehicular and pedestrian traffic, the detection of living beings and especially of humans, is a way of quantifying different variables pertinent to the improvement of roads, traffic flows, frequency of visits, among others. the implementation of low-cost systems that do not involve high-processing systems makes the solutions more scalable at a global level. The data acquired by this type of device offers advantages to the different entities in statistics and public consultations, thus contributing to their growth. In this article, an assistance system for the task of pedestrian flow detection is designed and constructed. It integrates strategically located arrays of sensors to detect the direction and general location, which include microwave sensors to detect motion, and infrared presence sensors. The results demonstrate that the system manages to establish the direction of flow of the individual and laterally of the displacement and differentiation between humans and objects for assistance to other systems of counting or analysis of pedestrian flow.

Perspectives of Muslim Religious Leaders to Shape an Educational Intervention About Family Planning in Rural Tanzania: A Qualitative Study.

INTRODUCTION: Uptake of effective contraceptive methods can be hindered by poor understanding and uncertainty about its compatibility with religious beliefs. We sought to understand the perspectives of Muslim religious leaders in rural Tanzania on family planning (FP) and acceptable strategies for providing FP education to leaders and their communities. METHODS: We conducted in-depth interviews with Muslim leaders from 4 communities in northwest Tanzania. Open-ended questions explored leaders' views on FP in relation to their communities, Muslim texts and teaching, and their experience as leaders. We also investigated how FP education could be provided in their communities and asked practical questions regarding seminar implementation. Interviews were conducted in Kiswahili and transcribed and translated into English. Data were coded independently by 2 investigators using NVivo 1.5.1 and analyzed thematically. RESULTS: We interviewed 17 male and 15 female Muslim leaders. All leaders supported FP as a concept in which births are spaced, interpreting this as espoused by the Qur'an and a basic right of children raised in Islam. Leaders uniformly endorsed the use of breastfeeding and the calendar method to space births but had divergent and sometimes opposing views on other methods, including condom use, oral contraceptives, and intrauterine devices. All leaders acknowledged the need for FP education among their congregants and were in favor of helping to teach an FP seminar in their communities. CONCLUSION: Our data reveal insights into how education for Muslim leaders may equip them to promote birth spacing and enhance understanding of FP in their communities in ways that are concordant with Islamic teaching. Our findings will guide the design and pilot-testing of an educational intervention for Muslim religious leaders to promote knowledge and uptake of FP in rural Tanzania.

Health providers' perspectives on contraceptive use in rural Northwest Tanzania: A qualitative study.

Objectives: In Tanzania, contraceptive use is limited, particularly in rural communities and even among women who would like to delay childbearing. This paper aims to present health providers' perspectives on populations seeking contraception and barriers that could be addressed to increase access to and uptake of contraception, given their interface with large portions of their communities. Study Design: We conducted 18 in-depth interviews with providers stationed at health dispensaries in six rural villages in northwest Tanzania. Two investigators independently coded interviews using a stepwise process to achieve consensus on prevalent topics. Results: Three topics emerged from our analysis: (1) nature of clients seeking contraception; (2) barriers to uptake of contraception; and (3) the role of secrecy in obtaining and using contraception. Health providers reported that married women with children were the most frequent users of contraception, alongside some single women, men, sex workers, and students. Barriers to contraception included lack of supplies and trained staff, misconceptions and fears, stigma, and unsupportive partners. Providers observed that contraception was often used secretly. They reported surreptitious visits and described clients' preferential use of discreet methods. Providers respected and supported clients' desires to keep visits confidential. Conclusion: Our data suggest maintaining high stocks of discreet contraceptive methods and deploying more trained staff to dispensaries could increase availability and access to contraceptives. At the community level, more education campaigns are warranted to address barriers, especially those related to stigma. Implications: Our work highlights the need for additional contraceptive methods that are easy to administer and discreet for women who must maintain secrecy. Future studies of the effectiveness of interventions and new contraceptives should obtain healthcare providers' perspectives, as they can provide important insights to service provision.

Healthcare Workers' Low Knowledge of Female Genital Schistosomiasis and Proposed Interventions to Prevent, Control, and Manage the Disease in Zanzibar.

Objectives: This study was conducted to explore healthcare workers' knowledge of female genital schistosomiasis (FGS) and describe proposed interventions to raise awareness about FGS and strengthen healthcare facilities' capacity to manage FGS cases. Methods: We conducted four cross-sectional focus group discussions and 16 key informant interviews with purposively selected healthcare workers in Zanzibar. Discussions and interviews were digitally recorded, transcribed, and analyzed using NVivo software. Results: Most participants had limited or no knowledge of FGS and lacked skills for managing it. They confused FGS with urogenital schistosomiasis and thought it was sexually transmitted. A few participants knew about FGS and associated it with Human Immunodeficiency Virus (HIV), ectopic pregnancy, cervical cancer, and infertility. To prevent and control FGS, participants proposed interventions targeting communities (including community-based health education) and the healthcare system (including training healthcare workers on FGS). Conclusion: Healthcare workers lacked knowledge of and skills for managing FGS. Besides, healthcare facilities had no diagnostic capacity to manage FGS. Along with on-going interventions to break S. haematobium transmission and eventually eliminate urogenital schistosomiasis in Zanzibar, we recommend training healthcare workers on FGS and equip healthcare facilities with medical equipment and supplies for managing FGS.
