Type I Brugada Pattern in a Febrile Patient Following COVID-19 Vaccination Booster.

There have been studies published regarding the association between developing Brugada syndrome after an acute COVID-19 infection. In this case, we present a patient who presented with a syncopal episode and subsequently found to have Type I Brugada pattern on electrocardiogram. The patient underwent placement of a single chamber defibrillator. Genetic analysis demonstrated SCN5A variant which is associated with cardiac conditions including Brugada syndrome.

Assessing the impact of the president's emergency plan for AIDS relief on all-cause mortality.

This study estimated the impacts of PEPFAR on all-cause mortality (ACM) rates (deaths per 1,000 population) across PEPFAR recipient countries from 2004-2018. As PEPFAR moves into its 3rd decade, this study supplements the existing literature on PEPFAR 's overall effectiveness in saving lives by focusing impact estimates on the important subgroups of countries that received different intensities of aid, and provides estimates of impact for different phases of this 15-year period study. The study uses a country-level panel data set of 157 low- and middle-income countries (LMICs) from 1990-2018, including 90 PEPFAR recipient countries receiving bilateral aid from the U.S. government, employing difference-in-differences (DID) econometric models with several model specifications, including models with differing baseline covariates, and models with yearly covariates including other donor spending and domestic health spending. Using five different model specifications, a 10-21% decline in ACM rates from 2004 to 2018 is attributed to PEPFAR presence in the group of 90 recipient countries. Declines are somewhat larger (15-25%) in those countries that are subject to PEPFAR's country operational planning (COP) process, and where PEPFAR per capita aid amounts are largest (17-27%). Across the 90 recipient countries we study, the average impact across models is estimated to be a 7.6% reduction in ACM in the first 5-year period (2004-2008), somewhat smaller in the second 5-year period (5.5%) and in the third 5-year period (4.7%). In COP countries the impacts show decreases in ACM of 7.4% in the first period attributed to PEPFAR, 7.7% reductions in the second, and 6.6% reductions in the third. PEPFAR presence is correlated with large declines in the ACM rate, and the overall life-saving results persisted over time. The effects of PEFAR on ACM have been large, suggesting the possibility of spillover life-saving impacts of PEPFAR programming beyond HIV disease alone.

Analysis of maternal and child health spillover effects in PEPFAR countries.

OBJECTIVES: This study examined whether the US President's Emergency Plan for AIDS Relief (PEPFAR) funding had effects beyond HIV, specifically on several measures of maternal and child health in low-income and middle-income countries (LMICs). The results of previous research on the question of PEPFAR health spillovers have been inconsistent. This study, using a large, multicountry panel data set of 157 LMICs including 90 recipient countries, adds to the literature. DESIGN: Seven indicators including child and maternal mortality, several child vaccination rates and anaemia among childbearing-age women are important population health indicators. Panel data and difference-in-differences estimators (DID) were used to estimate the impact of the PEPFAR programme from inception in 2004 to 2018 using a comparison group of 67 LMICs. Several different models of baseline (2004) covariates were used to help balance the comparison and treatment groups. Staggered DID was used to estimate impacts since all countries did not start receiving aid at PEPFAR's inception. SETTING: All 157 LMICs from 1990 to 2018. PARTICIPANTS: 90 LMICs receiving PEPFAR aid and cohorts of those countries, including those required to submit annual country operational plans (COP), other recipient countries (non-COP), and three groupings of countries based on cumulative amount of per capita aid received (high, medium, low). INTERVENTIONS: PEPFAR aid to combat the HIV epidemic. PRIMARY OUTCOME MEASURES: Maternal mortality and child mortality rates, vaccination rates to protect children for diphtheria, whooping cough and tetanus, measles, HepB3, and tetanus, and prevalence of anaemia in women of childbearing age. RESULTS: Across PEPFAR recipient countries, large, favourable PEPFAR health effects were found for rates of childhood immunisation, child mortality and maternal mortality. These beneficial health effects were large and significant in all segments of PEPFAR recipient countries studied. We also found significant and favourable programme effects on the prevalence of anaemia in women of childbearing age in PEPFAR recipient countries receiving the most intensive financial support from the PEPFAR programme. Other recipient countries did not demonstrate significant effects on anaemia. CONCLUSIONS: This study demonstrated that important health indicators, beyond HIV, have been consistently and favourably influenced by PEPFAR presence. Child and maternal mortality have been substantially reduced, and childhood immunisation rates increased. We also found no evidence of 'crowding out' or negative spillovers in these resource-poor countries. These findings add to the body of evidence that PEPFAR has had favourable health effects beyond HIV. The implications of these findings are that foreign aid for health in one area may have favourable health effects in other areas in recipient countries. More research is needed on the influence of the mechanisms at work that create these spillover health effects of PEPFAR.

Equity of the HIV epidemic response in 13 African countries.

For over 25 years, new programs to attempt to stem the HIV epidemic have been developed in Africa by country governments as well as external donors. These programs and activities have built and operated facilities, trained clinicians, financed drugs and commodities, supported and helped finance government health planning and operations, and contributed in other ways. Who has benefited from this massive mobilization? While some single country and narrowly focused studies have been done, the issue of equity of HIV programs for vulnerable populations has not been examined in a large set of countries. Using Population-based HIV Impact Assessment (PHIA) data, we examine equity of the HIV programs in 13 African countries to determine if vulnerable groups (such as those with low wealth, rural populations, young adults, and females) have achieved comparable levels of access to HIV program services. In contrast, we also compare the equity of the HIV response to rural and low-wealth populations with the equity of corresponding domestic health systems using Demographic and Health Survey data.This study found that in over half of the countries, the HIV response indicators were equitable for vulnerable population segments including the low-wealth population (in seven countries) and rural population segment (in nine countries). In no country was the domestic health system equitable for these two groups. However, HIV programming does show some clear patterns of inequity for low-wealth and rural populations in some countries. For gender and young adults, the HIV response indicators show that in all 13 countries men and young adults are consistently underserved relative to their counterparts.

Analysis of economic and educational spillover effects in PEPFAR countries.

The United States President's Emergency Plan for AIDS Relief (PEPFAR) has been credited with saving millions lives and helping to change the trajectory of the global human immunodeficiency virus (HIV) epidemic. This study assesses whether PEPFAR has had impacts beyond health by examining changes in five economic and educational outcomes in PEPFAR countries: the gross domestic product (GDP) per capita growth rate; the share of girls and share of boys, respectively, who are out of school; and female and male employment rates. We constructed a panel data set for 157 low- and middle-income countries between 1990 and 2018 to estimate the macroeconomic impacts of PEPFAR. Our PEPFAR group included 90 countries that had received PEPFAR support over the period. Our comparison group included 67 low- and middle-income countries that had not received any PEPFAR support or had received minimal PEPFAR support (<$1M or <$.05 per capita) between 2004 and 2018. We used differences in differences (DID) methods to estimate the program impacts on the five economic and educational outcome measures. This study finds that PEPFAR is associated with increases in the GDP per capita growth rate and educational outcomes. In some models, we find that PEPFAR is associated with reductions in male and female employment. However, these effects appear to be due to trends in the comparison group countries rather than programmatic impacts of PEPFAR. We show that these impacts are most pronounced in COP countries receiving the highest levels of PEPFAR investment.

Costing of HIV services, Uganda and United Republic of Tanzania.

Objective: To evaluate resource allocation and costs associated with delivery of human immunodeficiency virus (HIV) services in Uganda and the United Republic of Tanzania. Methods: We used time-driven activity-based costing to determine the resources consumed and costs of providing five HIV services in Uganda and the United Republic of Tanzania: antiretroviral therapy (ART); HIV testing and counselling; prevention of mother-to-child transmission; voluntary male medical circumcision; and pre-exposure prophylaxis. Findings: Country-based teams undertook time-driven activity-based costing with 1119 adults in Uganda and 886 adults in the United Republic of Tanzania. In Uganda, service delivery costs ranged from 8.18 United States dollars (US$) per visit for HIV testing and counselling to US$ 43.43 for ART (for clients in whom HIV was suppressed). In the United Republic of Tanzania, these costs ranged from US$ 3.67 per visit for HIV testing and counselling to US$ 28.00 for voluntary male medical circumcision. In both countries, consumables were the main cost driver, accounting for more than 60% of expenditure. Process maps showed that in both countries, registration, measurement of vital signs, consultation and medication dispensing were the steps that occurred most frequently for ART clients. Conclusion: Establishing a rigorous, longitudinal system for tracking investments in HIV services that includes thousands of clients and numerous facilities is achievable in different settings with a high HIV burden. Consistent engagement of implementation partners and standardized training and data collection instruments proved essential for the success of these exercises.

National Evaluation of HIV Service Resource Allocation in Tanzania.

Using time-driven activity-based costing (TDABC), we examined resource allocation and costs for HIV services throughout Tanzania at patient and facility levels. This national, cross-sectional analysis of 22 health facilities quantified costs and resources associated with 886 patients receiving care for five HIV services: antiretroviral therapy, prevention of mother-to-child transmission, HIV testing and counseling, voluntary medical male circumcision, and pre-exposure prophylaxis. We also documented total provider-patient interaction time, the cost of services with and without inclusion of consumables, and conducted fixed-effects multivariable regression analyses to examine patient- and facility-level correlates of costs and provider-patient time. Findings showed that resources and costs for HIV care varied significantly throughout Tanzania, including as a function of patient- and facility-level characteristics. While some variation may be preferable (e.g., needier patients received more resources), other areas suggested a lack of equity (e.g., wealthier patients received more provider time) and presented opportunities to optimize care delivery protocols.

Single-anastomosis duodenoileal bypass with sleeve in the United States: a first comparative safety analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database.

BACKGROUND: The single-anastomosis duodenoileal bypass with sleeve (SADI-S) is a relatively new bariatric procedure. In 2020, the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) started reporting outcomes for SADI-S. OBJECTIVES: We aimed to study the perioperative safety of SADI-S and compare it with other established bariatric procedures utilizing the MBSAQIP database. SETTING: Academic hospital, United States. METHODS: The 2020 MBSAQIP Participant Use File was used to evaluate SADI-S outcomes. We included SADI-S primary cases and excluded revisions and concurrent operations. A 5:1 propensity matched analysis (PMA) for 20 variables was performed to compare the outcomes of the SADI-S with the Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) and a 2:1 PMA to the biliopancreatic diversion with duodenal switch (BPD/DS). RESULTS: There were 255 primary SADI-S reported in 2020. After PMA, the only significant complications between the RYGB and SADI-S cohorts were Clavien-Dindo grade IVa and IVb (.1% and 1.4% versus 1.6% and 7.1%, respectively). SADI-S had more Clavien-Dindo grade II, IVa, and IVb complications than the SG cohort (1.3% versus 3.5%, P = .03; .2% versus 1.6%, P = 0; 1.% versus 7.1%, P = 0). When compared with BPD/DS, outcomes including readmission, reoperation, and intervention were not statistically significant. CONCLUSION: SADI-S, in its early adoption stage, has a higher incidence of perioperative complications than RYGB and SG. It has comparable 30-day outcomes to BPD/DS.

Host Tau Genotype Specifically Designs and Regulates Tau Seeding and Spreading and Host Tau Transformation Following Intrahippocampal Injection of Identical Tau AD Inoculum.

Several studies have demonstrated the different characteristics of tau seeding and spreading following intracerebral inoculation in murine models of tau-enriched fractions of brain homogenates from AD and other tauopathies. The present study is centered on the importance of host tau in tau seeding and the molecular changes associated with the transformation of host tau into abnormal tau. The brains of three adult murine genotypes expressing different forms of tau-WT (murine 4Rtau), hTau (homozygous transgenic mice knock-out for murine tau protein and heterozygous expressing human forms of 3Rtau and 4Rtau proteins), and mtWT (homozygous transgenic mice knock-out for murine tau protein)-were analyzed following unilateral hippocampal inoculation of sarkosyl-insoluble tau fractions from the same AD and control cases. The present study reveals that (a) host tau is mandatory for tau seeding and spreading following tau inoculation from sarkosyl-insoluble fractions obtained from AD brains; (b) tau seeding does not occur following intracerebral inoculation of sarkosyl-insoluble fractions from controls; (c) tau seeding and spreading are characterized by variable genotype-dependent tau phosphorylation and tau nitration, MAP2 phosphorylation, and variable activation of kinases that co-localize with abnormal tau deposits; (d) transformation of host tau into abnormal tau is an active process associated with the activation of specific kinases; (e) tau seeding is accompanied by modifications in tau splicing, resulting in the expression of new 3Rtau and 4Rtau isoforms, thus indicating that inoculated tau seeds have the capacity to model exon 10 splicing of the host mapt or MAPT with a genotype-dependent pattern; (e) selective regional and cellular vulnerabilities, and different molecular compositions of the deposits, are dependent on the host tau of mice injected with identical AD tau inocula.

Antiplatelet Agent Reversal Is Unnecessary in Blunt Traumatic Brain Injury Patients Not Requiring Immediate Craniotomy.

BACKGROUND: The need to reverse the coagulation impairment caused by chronic antiplatelet agents in traumatic brain injury (TBI) patients with acute traumatic intracerebral hemorrhage (TICH) remains controversial. We sought to determine whether emergent platelet transfusion reduces the incidence of hemorrhage expansion, mortality, or need for neurosurgical intervention such as intracranial pressure (ICP) monitoring, burr holes, or craniotomy. METHODS: All adult blunt TICH patients (age ≥16 years) over a 4-year period were retrospectively reviewed. Patients with penetrating TBI, blunt TBI without TICH on admission computed tomography (CT), receiving warfarin, not on antiplatelet agents, or requiring immediate operative intervention were excluded. Patients were divided into 2 groups depending on whether they received a platelet transfusion: reversal group (RV) versus no reversal group (NR). Patient outcomes were analyzed using Mann-Whitney U and Fisher's exact tests. RESULTS: 169 blunt TBI patients on chronic antiplatelet therapy were studied (102 RV group, 67 NR group). The groups were well matched with regard to age, Injury Severity Score, Abbreviated Injury Scale-head, Glasgow Coma Score, mechanism of injury, need for intubation, time to initial CT scan, and hospital length of stay. Immediate platelet transfusion did not alter the occurrence of TICH extension on follow-up CT (26% vs 21%, P = .71), TBI-specific mortality (9% vs 13%, P = .45), need for ICP monitor (2% vs 3%, P = 1.0), burr hole (1% vs 3%, P = .56), or craniotomy (1% vs 3%, P = .56). DISCUSSION: Immediate platelet transfusion is unnecessary in blunt TBI patients on chronic antiplatelet therapy who do not require immediate craniotomy.

Virtual keyboard with the prediction of words for children with cerebral palsy.

One in every 200 people worldwide cannot express orally because of cognitive, motor, neurological, or emotional problems. Assistive technologies can help people with impairments to use computers to perform their daily life activities independently and to communicate with others. This paper presents a Hidden Markov Model-based word prediction method that allows keyboard emulation software to predict words so that children with disabilities can type texts more quickly. The proposed system involved the development of a keyboard emulator, the construction and processing of a corpus, as well as a word prediction algorithm. Children with different cognitive profiles had to produce a text and type it twice: first with free typing, second using the virtual keyboard's word prediction. Results indicated the word prediction of the keyboard emulator software reduced typing efforts. However, the software initially increased the typing time when the corpus was not well adapted to users. The total amount of clicks with word prediction decreased by around 26.2%. Regarding execution time using prediction, 61% typed the text in less time. The tests performed with literate volunteers indicated a reduction in the number of clicks by up to 51.3%. This result surpasses the 15% achieved in the previous study by Free Virtual Keyboard with word prediction based on pure statistics. Moreover, all volunteers required fewer clicks to perform the task. People with impairments, especially children, could use the system and demonstrate their knowledge and abilities. The entire system is available on the Internet and users have unrestricted and free access to it.

Cost Effectiveness of Mobile Health for Antenatal Care and Facility Births in Nigeria.

BACKGROUND: The use of mobile technology in the health sector, often referred to as mHealth, is an innovation that is being used in countries to improve health outcomes and increase and improve both the demand and supply of health care services. This study assesses the actual cost-effectiveness of initiating and implementing the use of the mHealth as a supply side job aid for antenatal care. The study also estimates the cost-effectiveness ratio if mHealth was also used to encourage and track women through facility delivery. METHODS: The methodology utilized a retrospective, micro-costing technique to extract costing data from health facilities and administrative offices to estimate the costs of implementing the mHealth antenatal care program and estimate the cost of facility delivery for those that used the antenatal care services in the year 2014. Five different costing tools were developed to assist in the costing analysis. FINDINGS: The results show that the provision of tetanus toxoid vaccination and malaria prophylaxis during pregnancy and improved labor and delivery during facility delivery contributed the most to mortality reductions for women, neonates and stillbirths in mHealth facilities versus non-mHealth facilities. The cost-effectiveness ratio of this program for antenatal care and no demand-side generation for facility delivery is US$13,739 per life saved. The cost-effectiveness ratio adding in an additional demand-side generation for facility births reduces to US$9,806 per life saved. CONCLUSION: These results show that mHealth programs are inexpensive and save a number of lives for the dollar investment and could save additional lives and funds if women were also encouraged to seek facility delivery.

Household Food Insecurity and Sleep Patterns Among Mexican Adults: Results from ENSANUT-2012.

To examine the independent association of household food insecurity with sleep duration and quality in a nationally representative survey of adults in Mexico. The Latin American and Caribbean Food Security Scale was used to categorize households as secure, mild (43.7 %), moderate (19.0 %), or severe (11.8 %). We assessed the association between household food insecurity and self-reported sleep duration and quality among 11,356 adults using weighted multinomial and binomial logistic regression. After adjusting for potential confounders, a significant association was found between severe household food insecurity and getting less than the recommended 7-8 h of sleep [adjusted odds ratio (AOR) =1.83, 95 % confidence interval (CI) =1.37-2.43]. Compared with food-secure households, odds of poor sleep quality increased with level of severity (AOR = 1.27, 95 % CI 1.04-1.56 for mild; AOR = 1.71, 95 % CI 1.36-2.14 for moderate; and AOR = 1.89, 95 % CI 1.45-2.45 for severe household food insecurity). Household food insecurity is associated with inadequate sleep duration and poor sleep quality among Mexican adults. This study underscores the adverse effects of household food insecurity on the well-being of vulnerable populations.

Software livre de produção textual com predição de palavras: um aliado do aluno especial / Text production with a word predicition free-ware software: support for the special student

A dificuldade em comunicar-se naturalmente, seja através da fala ou da escrita, pode fazer com que uma pessoa seja impedida de demonstrar e desenvolver seus potenciais cognitivos, sociais e criativos. Essa realidade tem sido amplamente estudada, buscando cada vez mais e melhores soluções que contornem tal limitação, pela ciência multidisciplinar conhecida como Comunicação Alternativa e Aumentativa. Dentre as soluções encontradas, algumas delas fazem uso do computador como ferramenta de apoio à comunicação. A predição de palavras e simuladores de teclado para produção textual estão entre essas soluções. Este artigo vem divulgar e discutir os resultados obtidos com a aplicação de um simulador de teclado em conjunto com uma técnica de predição de palavras baseada nos grupos das classes gramaticais da língua portuguesa, o qual oferece ao usuário facilitação na produção de textos com qualidade gramatical. Dados obtidos com adolescentes com seqüelas de paralisia cerebral mostraram que o uso do aplicativo é construtivo, amplia a comunicação e pode auxiliar no processo de aprendizado da língua portuguesa. Ampliar a comunicação sem prejudicar a qualidade gramatical é uma forma de auxiliar no processo de educação e inclusão social de pessoas com deficiência, tornando-as socialmente mais participativas e melhorando a qualidade de suas vidas.

The difficulty in communicating naturally, through speech or writing, can impede a person demonstrating and developing his or her cognitive, social and creative abilities. This reality has been thoroughly studied, looking for more and better solutions to circumvent said limitation, using the multidisciplinary science known as Alternative and Augmentative Communication. Among the proposed solutions, some use computers as a tool to support communication. Word prediction and on-screen keyboard simulators used for writing are among such facilitators. This paper presents and discusses the results obtained when keyboard simulator were applied along with word prediction techniques based on grammatical class groups for the Portuguese language; this proposal facilitates writing production with good grammatical quality. Data obtained with adolescents with sequelae from cerebral palsy showed that the use of the software was positive, as it enhanced communication and was useful in the learning process for the Portuguese language. Broadening communication possibilities without prejudice to grammatical quality is a means of aiding in the educational process and social inclusion for people with special needs, so as to enhance social participation and improve quality of life.
