Choice of end-state comfort is dependent upon the time spent at the beginning-state and the precision requirement of the end-state.

Choice of posture while grasping an object typically depends upon several factors including the time spent in that posture, what postures were held prior to choosing that posture, and the precision required by the posture. The purpose of this study was to test choice of end-state thumb-up posture based on time spent at the beginning-state and the precision requirement of the end-state. To determine choice of thumb-up based on time or precision, we varied how long a subject had to hold the beginning state before moving an object to an end location. We made end-state precision either small or large and eliminated the precision needed to stand the object up at the end of the movement. A choice between "comfort" at the beginning or precision at the end-state would be demanded by the conditions with long beginning-state hold times and high precision demands. We aimed to determine which aspect of movement was of greater importance to individuals, overall "comfort" or precision. When the requirement was to hold the initial grasp longer, and the end-target was large, we predicted that we would see more thumb-up postures adopted at the beginning state. When the final placement was small and the initial posture was not constrained, we predicted we would see thumb-up postures adopted at the end state. On average, we found that, as beginning-state grasp time increased, more individuals chose beginning-state thumb-up postures. Perhaps, not surprisingly, we found distinct individual differences within our sample. Some individuals seemed to choose beginning-state thumb-up postures nearly 100% of the time, while other individuals chose end-state thumb-up postures nearly 100% of the time. Both the time spent in a posture and its precision requirements influenced planning, but not necessarily in a systematic way.

Comparative changes in emergency department patient attendance at the pediatric emergency hospital during the first wave between 2019 and 2020. / Cambios comparativos en la asistencia de pacientes al servicio de emergencia durante la primera ola en el Hospital de Emergencias Pediátricas entre el 2019 y 2020.

The COVID-19 pandemic changed the pattern of patient attendance at healthcare facilities. We describe the comparative changes in the attendance of pediatric patients at the Emergency Department of the Pediatric Emergency Hospital of Lima, Peru, between epidemiological weeks 10 to 48 of 2019 and 2020. Sociodemographic data, patient condition, type of insurance and diagnosis grouped according to ICD-10 code were analyzed. We found a 48.2% reduction in the number of visits in 2020 when compared to 2019, and a five-fold increase in the number of visits from localities other than Metropolitan Lima. Likewise, the probability of diagnosis of "infectious and parasitic diseases" increased by 27% and the probability of diagnosis of "diseases of the respiratory system" decreased by 61%.

A Chikungunya Outbreak in a Dengue-endemic Region in Rural Northern Coastal Ecuador.

Dengue virus (DENV) reemerged in the Americas in the 1980s and 1990s, whereas chikungunya virus (CHIKV) emerged in 2014. Although CHIKV produced large epidemics from 2014 to 2017, dengue fever has been the prominent arboviral disease identified through passive surveillance, bringing to question the degree to which cases are misdiagnosed. To address this concern, we conducted an active household-based surveillance of arboviral-like illnesses in six rural and remote communities in northern coastal Ecuador from May 2019 to February 2020. Although passive surveillance conducted by the Ecuadorian Ministry of Health reported only DENV cases in the region, more than 70% of the arbovirus-like illnesses detected by active surveillance in our study were positive for CHIKV. These findings underline the need for active surveillance of arboviral infections with laboratory confirmation, especially in rural communities where arboviral illnesses are more likely to be underreported.

Association between lead source exposure and blood lead levels in some lead manufacturing countries: A systematic review and meta-analysis.

Lead is one of the 10 most toxic chemicals of greatest concern for its effects on public health. Predominantly, in undeveloped countries, high blood lead levels (BLLs) persist in the population. To develop intervention strategies that may reduce lead exposure in populations, it is a priority to know the sources of lead pollution. The objective of this critical review and meta-analysis is to assess whether there is an association between different sources of lead exposure and the mean difference in blood lead levels in people exposed. To identify the major lead source exposure, a statistical analysis was performed on selection studies. This investigation reveals the limited information available on the sources of lead in Mexico and other lead producer countries, such as Croatia, Ecuador, Brazil, South Korea, India, Nigeria, Turkey, and China. Meta-analysis could be performed only in battery, smelting mining, and glazed ceramic workers. Battery manufacturing workers have the highest mean difference level of lead in their blood worldwide. Mexico has the second highest mean difference BLL in battery workers in the world. An interesting difference between the mean difference in BLL in mining workers from uncontrolled industry (-39.38) and controlled industry (-5.68) was found. This difference highlighted the success of applying strict control of lead sources and community education to reduce BLL and its potential harmful effects on human health and the environment. Children living near mining sites have the highest mean difference BLL (-11.1). This analysis may aid in assessing the source of lead exposure associated with a range of BLLs in people. Furthermore, this review highlights several social and cultural patterns associated with lead exposure and lead levels in control populations. These results could help to develop international lead regulations and appropriate public health guidelines to protect people around the world.

[Helicobacter pylori infection and relationship with endoscopic findings in patients treated at a referral endoscopic center in Panama]. / Infección por Helicobacter pylori y relación con hallazgos endoscópicos en pacientes atendidos en un centro endoscópico de referencia en Panamá.

INTRODUCTION: Helycobacter pylori (HP) infection is a public health problem in Latin America with a prevalence of infection of up to 70%. There are endoscopic findings associated with the presence of infection, however we do not know the current prevalence in Panama and if the endoscopic findings are related to HP infection. OBJECTIVE: To assess the frequency of HP infection in patients who underwent upper gastrointestinal endoscopy and its association with HP infection. MATERIALS AND METHODS: An observational, cross-sectional and analytical study was carried out from January 1, 2019 to December 31, 2019 in the Gastroenterology service of Hospital Santo Tomás, Panama city. The frequency of HP infection in patients who underwent upper gastrointestinal endoscopy and the association of endoscopic findings with HP infection was evaluated. RESULTS: In total, 1,281 digestive endoscopies were performed. 21.4% of the patients included in the study confirmed HP infection. In endoscopic findings, the presence of nodular gastritis has an association OR 4.32 (2.74-6.80) with the presence of HP infection. The presence of duodenal ulcer and gastric ulcer were also significantly associated with the presence of HP infection, OR 3.71 (1.21-11.35) and OR: 2.59 (1.36-5.16). CONCLUSION: This is the first study in Panama to evaluate the association of endoscopic findings and the prevalence in a cohort of patients with an indication for upper endoscopy with the probability of Helicobacterpylori infection in the last decade. We conclude that certain endoscopic findings in an appropriate clinical context could increase the diagnostic probability of HP infection in patients seen in Panama.

Indigenous Ethnicity and Low Maternal Education Are Associated with Delayed Diagnosis and Mortality in Infants with Congenital Heart Defects in Panama.

BACKGROUND: This is the first study in Panama and Central America that has included indigenous populations in an assessment of the association between socioeconomic variables with delayed diagnosis and mortality due to congenital heart defects (CHD). METHODS: A retrospective observational study was conducted. A sample calculation was performed and 954 infants born from 2010 to 2014 were randomly selected from clinical records of all Panamanian public health institutions with paediatric cardiologists. Critical CHD was defined according to the defects listed as targets of newborn pulse oximetry screening. Diagnoses were considered delayed when made after the third day of life for the critical CHD and after the twentieth day of life for the non-critical. A logistic regression model was performed to examine the association between socioeconomic variables and delayed diagnosis. A Cox proportional hazards model was used to assess the relationship between socioeconomic features and mortality. RESULTS: An increased risk of delayed diagnosis was observed in infants with indigenous ethnicity (AOR, 1.56; 95% CI, 1.03-2.37), low maternal education (AOR, 1.57; 95% CI, 1.09-2.25) and homebirth (AOR, 4.32; 95% CI, 1.63-11.48). Indigenous infants had a higher risk of dying due to CHD (HR, 1.43; 95% CI, 1.03-1.99), as did those with low maternal education (HR, 1.95; 95% CI, 1.45-2.62). CONCLUSION: Inequalities in access to health care, conditioned by unfavourable socioeconomic features, may play a key role in delayed diagnosis and mortality of CHD patients. Further studies are required to study the relationship between indigenous ethnicity and these adverse health outcomes.

The combined-disk boronic acid test as an accurate strategy for the detection of KPC carbapenemase in Central America.

INTRODUCTION: Carbapenemase-producing Klebsiella pneumoniae (KPC) outbreaks may cause a huge economical burden on developing countries. Furthermore, KPC can be challenging to detect. We describe the laboratory strategy for the detection of KPC from 2011 to 2013 in a tertiary care hospital in Central America with approximately 1,000 beds. METHODOLOGY: A retrospective analysis of a clinical laboratory database was done to determine the pragmatic application of the combined-disk boronic acid test during a KPC outbreak in Panama. A total of 1,026 Klebsiella pneumoniae isolates were found, of which 133 were positive for KPC. The strategy during two phases was described according to the test employed as a confirmatory test for KPC. After the K. pneumoniae isolates were detected by the VITEK 2 system, blaKPC polymerase chain reaction (PCR) and the combined-disk boronic acid test were employed as a confirmatory test during phase one. The combined-disk boronic acid test was employed as a confirmatory test for KPC during phase two. RESULTS: The sensitivity, specificity, positive predictive value, and negative predictive value of the boronic acid test were 100%, 97%, 91%, and 100%, respectively, when blaKPC PCR was employed as a confirmatory test during the start of the outbreak. Afterwards, modified VITEK 2 system parameters resulted in 116 suspicious KPC samples and the boronic acid test confirmed 102 isolates. CONCLUSIONS: The use of an automated bacterial identification system and the boronic acid test for the detection of KPC was an effective and low-cost strategy for a clinical laboratory in Panama during an outbreak.

Assessment of the Possible Association of Air Pollutants PM10, O3, NO2 With an Increase in Cardiovascular, Respiratory, and Diabetes Mortality in Panama City: A 2003 to 2013 Data Analysis.

In recent years, Panama has experienced a marked economic growth, and this, in turn, has been associated with rapid urban development and degradation of air quality. This study is the first evaluation done in Panama on the association between air pollution and mortality. Our objective was to assess the possible association between monthly levels of PM10, O3, and NO2, and cardiovascular, respiratory, and diabetes mortality, as well as the seasonal variation of mortality in Panama City, Panama.The study was conducted in Panama City, using air pollution data from January 2003 to December 2013. We utilized a Poisson regression model based on generalized linear models, to evaluate the association between PM10, NO2, and O3 exposure and mortality from diabetes, cardiovascular, and respiratory diseases. The sample size for PM10, NO2, and O2 was 132, 132, and 108 monthly averages, respectively.We found that levels of PM10, O3, and NO2 were associated with increases in cardiovascular, respiratory, and diabetes mortality. For PM10 levels ≥ 40 µg/m3, we found an increase in cardiovascular mortality of 9.7% (CI 5.8-13.6%), and an increase of 12.6% (CI 0.2-24.2%) in respiratory mortality. For O3 levels ≥ 20 µg/m3 we found an increase of 32.4% (IC 14.6-52.9) in respiratory mortality, after a 2-month lag period following exposure in the 65 to <74 year-old age group. For NO2 levels ≥20 µg/m3 we found an increase in respiratory mortality of 11.2% (IC 1.9-21.3), after a 2-month lag period following exposure among those aged between 65 and <74 years.There could be an association between the air pollution in Panama City and an increase in cardiovascular, respiratory, and diabetes mortality. This study confirms the urgent need to improve the measurement frequency of air pollutants in Panama.

Analysis of mortality trends due to cardiovascular diseases in Panama, 2001-2014.

OBJECTIVE: Cardiovascular diseases (CVDs) are still the leading cause of death worldwide despite the recent decline in mortality rates attributable to CVD in Western Europe and the Americas. The aim of this study is to investigate mortality trends due to ischaemic heart disease (IHD) and stroke in Panama from 2001 to 2014, as well as the mortality differences by sex and age groups. METHODS: Data were obtained from the National Mortality Register. The International Classification of Diseases 10th revision codes (ICD-10) I20-I25 and I60-I69 were used for IHD and stroke, respectively. Age-adjusted mortality rates were calculated using the world population of the WHO as standard. Trends were analysed using Joinpoint Regression Program and annual percentage changes (APC) were estimated. RESULTS: From 2010, the IHD mortality trend began to decline in the whole population of Panama (APC -4.7%, p<0.05). From 2001 to 2014, a decline in the trend for IHD mortality was observed (APC -1.7%, p<0.05) in women, but not in men. Stroke mortality showed a significant annual decline during the study period (APC -3.8%, p<0.05) and it was more pronounced in women (APC -4.5%, p<0.05) than in men (APC -3.3%, p<0.05). CONCLUSIONS: In Panama, the mortality rates from IHD and stroke have declined in recent years. Better access to healthcare, improved treatment of acute IHD and stroke, low tobacco consumption and better control of hypertension probably account for a significant part of this mortality reduction.
