Malnutrición e inadecuados hábitos de alimentación en bomberos de Panamá

La malnutrición por exceso es un problema de salud pública en Panamá. En bomberos, la malnutrición tiene graves implicaciones en la salud. El objetivo del presente estudio fue evaluar el estado nutricional, los hábitos alimentarios y el riesgo cardiovascular de unidades del Benemérito Cuerpo de Bomberos de la Región de Panamá Oeste en Panamá. Se realizó un estudio descriptivo y transversal de marzo a diciembre 2022. Para la recopilación de hábitos alimentarios se utilizó el formulario de frecuencia de consumo. Para la evaluación nutricional se midió peso, talla y circunferencia de la cintura. El riesgo cardiovascular fue estimado a partir de la razón cintura-altura (WHtR, por su acrónimo en inglés). Se evaluaron 100 participantes (79% son hombres) con edad entre 18 a 60 años. El exceso de peso se observó en el 88%, la obesidad en el 58%. El 97% consume frituras y 94% consume bebidas azucaradas. Solo el 20% y 16% consume vegetales y frutas diariamente. El 51% presenta riesgo cardiovascular por WHtR, siendo 39.2% en hombres y 95% en mujeres (p= 0.000). Se observa una alta proporción de exceso de peso, obesidad, obesidad abdominal y riesgo cardiovascular entre los bomberos evaluados. Bajo consumo de frutas y vegetales junto con un alto consumo de bebidas azucaradas y frituras. Es necesario implementar programas de prevención y control de la obesidad, así como brindar educación en alimentación y nutrición para abordar estos problemas de salud.

Malnutrition is a public health problem in Panama. In firefighters, malnutrition has serious health implications. We aim to evaluate the nutritional status, eating habits, and cardiovascular risk of units of the Fire Department of the West Panama Region in Panama. A descriptive and cross-sectional study was carried out from March to December 2022. For the collection of eating habits, a food frequency questionnaire was used. Weight, height, and waist circumference were used for the nutritional status evaluation. Cardiovascular risk was estimated from the waist-height ratio (WHtR). 100 participants (79% are men) aged between 18 and 60 years were evaluated. Excess weight was observed in 88%, and obesity in 58%. Cardiovascular risk by WHtR was presented in 51%, 39.2% of males, and 95% of females (p= 0.000). 97% consume fried foods and 94% consume sugary drinks. Only 20% and 16% consume vegetables and fruits daily. A high proportion of excess weight, obesity, abdominal obesity, and cardiovascular risk among the evaluated firefighters was observed. Low consumption of fruits and vegetables along with a high consumption of sugary drinks and fried foods. It is necessary to implement obesity prevention and control programs, as well as provide food and nutrition education to address these health problems.

Prevalencia y etiología de la anemia en Panamá

Desde 1998, el Ministerio de Salud de Panamá desarrolla un programa nacional de suplementación con hierro de forma preventiva en grupos de riesgo. El objetivo del estudio fue determinar las prevalencia total de anemia y de anemia ferropriva en una muestra representativa nacional de lactantes, preescolares, escolares y embarazadas, pertenecientes a distritos prioritarios y escolares de distritos prioritarios y no prioritarios. Se determinaron Hb, VCM, zinc-protoporfirina, ferritina sérica, proteína C reactiva (PCR) y solubilidad de hemoglobina. La Anemia ferropriva se definió como anemia con dos o más indicadores de nutrición de hierro alterados. Dado que un alto porcentaje de los sujetos presentó una PCR elevada, se utilizó un punto de corte para la ferritina de 50 ug/l. La prevalencia de anemia fue 66% en niños de 9 a 15 meses de edad, 41.8% en niños de 16 a 59 meses, 6.3% en escolares y 23.4% en embarazadas, mientras la prevalencia de anemia ferropriva fue 48.8%, 20.3%, 2.5% y 9.4%, respectivamente en embarazadas. La portación de drepanocitosis fue <2.5%. Conclusión: La anemia ferropriva tiene una alta prevalencia y es la principal causa de anemia en lactantes y preescolares. En embarazadas y escolares los procesos infecciosos constituirían la principal etiología de la anemia. La baja prevalencia de anemia ferropriva en escolares y embarazada es atribuible a la efectividad de la suplementación con hierro. Se requiere de la mejoría de la efectividad del programa nacional de suplementación y medidas destinadas a disminuir la incidencia de infecciones para reducir la prevalencia global de anemia en la población panameña.

From 1998, the Ministry of Health of Panama has a national program of prophylactic iron supplementation of risk groups. The objective of the study was to determine the prevalence anemia and of iron deficiency anemia (IDA) in a national representative sample of infants, preschool children and pregnant women from high-priority districts and scholar children from high-priority and not high-priority districts. Hb, MCV, zinc-protoporphyrin, serum ferritin, C reactive protein (CRP) and hemoglobin solubility were measured. IDA was defined as anemia plus two or more abnormal iron nutrition status. Since most of the subjects presented a high CRP, a 50 ug/l cutoff was used for serum ferritin. The prevalence of anemia was 66% in children from 9 to 15 months of age, 41.8% in children of 16 to 59 months, 6.3% in school children and 23.4% in pregnant women, whereas IDA prevalence was 48.8%, 20.3%, 2.5% and 9.4%, respectively. Sickle-cell trait was found in <2.5 % of the subjects. Conclusion, IDA was highly prevalent and the main cause of anemia in infants and preschool children. Infectious processes would constitute the main etiology of anemia in school children and pregnant women. The low prevalence of IDA in scholars and pregnant women is attributable to the effectiveness of the iron supplementation. The improvement of the effectiveness of the national iron supplementation program together with measures to diminish the incidence of infections are required to reduce the prevalence of anemia in the Panamanian population.

Diagnostic accuracy of combined 99mTc-sulesomab and 99mTc-nanocolloid bone marrow imaging in detecting prosthetic joint infection.

OBJECTIVE(S): Autologous-labeled leukocytes combined with sulfur colloid bone marrow scan is the current nuclear medicine gold standard for the diagnosis of prosthetic joint infection. The goal of this study is to assess the diagnostic accuracy of a new nuclear medicine modality for detecting infection in this context. METHODS: Twenty-seven patients with suspicious hip and knee arthroplasties were enrolled prospectively and underwent nuclear medicine testing using 99mTc-sulesomab and 99mTc-nanocolloids sequentially. These results were then crossed with the final diagnosis to determine the test(s) diagnostic accuracy. RESULTS: An isolated 99mTc-sulesomab scan shows 100% sensitivity (0.40-1) and negative predictive value (0.31-1) but only 20% specificity (0.05-0.48). Combining it with a 99mTc-nanocolloid bone marrow scan increases the specificity (0.75-1) and the positive predictive value (0.40-1) to 100%. Furthermore, the combined test has fewer equivocal readings and higher interreader agreement: κ test value 0.59 vs. 0.44. CONCLUSION: The results support the hypothesis that these technically simpler and ready-to-use products may be an alternative to autologous-labeled leukocytes/sulfur colloid marrow scan.

Adaptación y validación al español del disordered eating attitude scale (DEAS) / Adaptation and validation of the spanish version of the disordered eating attitude scale (DEAS)

Introducción: las creencias, pensamientos, sentimientos, comportamientos y la relación con los alimentos, en su conjunto, constituyen las actitudes alimentarias. Objetivo: desarrollar la versión en español del Disordered Eating Attitude Scale y realizar su evaluación psicométrica. Materiales y métodos: la encuesta original en portugués fue traducida al idioma español, re-traducida y comparada a la versión original, no presentando discrepancias. Se le denominó “Encuesta de actitudes alimentarias” (EAA) y fue aplicada a estudiantes universitarias de habla hispana (n=218). La consistencia interna fue determinada mediante el Alfa de Cronbach. La validez convergente fue establecida por correlación (Spearman) entre la EAA y el Test de Actitudes Alimentarias-26 (EAT-26). La fiabilidad fue evaluada aplicando dos veces (test-retest) la EAA en una sub-muestra (n=26), con diferencia de 30 días utilizando el coeficiente de correlación de Spearman (r). Resultados: la consistencia interna fue de 0,70. Hubo asociación significativamente positiva entre el puntaje total de la EAA con el puntaje obtenido mediante el EAT-26 (r=0,54). La correlación entre el test-retest fue de 0,81. Conclusión: la versión en español de la EAA es fiable, válida y precisa y será de utilidad para evaluar actitudes alimentarias en diferentes grupos poblacionales y en pacientes con trastornos alimentarios en países de habla hispana.

Introduction: the beliefs, thoughts, feelings, behaviors and relationship with food, all together, constitute eating attitudes. Objective: to develop and perform the psychometric evaluation of the Spanish version of the Disordered Eating Attitude Scale (DEAS). Methods: the original scale was translated into Spanish, back translated and compared to the original version; discrepancies were not observed. The Spanish version was applied to Hispanic undergraduate female college students (n=218). Internal consistency was determined using Cronbach´s Alpha; convergent validity was assessed by correlation (Spearman) between Spanish DEAS and the Eating Attitude Test -26 (EAT-26). Reliability was evaluated applying twice the scale to a sub-sample (n=26) within a 30 days interval. Spearman's correlation coefficient (r) was used to compare the test and retest scores. Results: internal consistency was 0,70. The DEAS total score was significantly associated with EAT-26 scores (r=0,54). The correlation between test-retest was r=0.81. Conclusion: the Spanish version of DEAS is reliable, valid and precise and will be useful to evaluate eating attitudes in different population groups and in eating disorder patients in Spanish spoken countries.

Performance of six severity-of-illness scores in cancer patients requiring admission to the intensive care unit: a prospective observational study.

INTRODUCTION: The aim of this study was to evaluate the performance of five general severity-of-illness scores (Acute Physiology and Chronic Health Evaluation II and III-J, the Simplified Acute Physiology Score II, and the Mortality Probability Models at admission and at 24 hours of intensive care unit [ICU] stay), and to validate a specific score - the ICU Cancer Mortality Model (CMM) - in cancer patients requiring admission to the ICU. METHODS: A prospective observational cohort study was performed in an oncological medical/surgical ICU in a Brazilian cancer centre. Data were collected over the first 24 hours of ICU stay. Discrimination was assessed by area under the receiver operating characteristic curves and calibration was done using Hosmer-Lemeshow goodness-of-fit H-tests. RESULTS: A total of 1257 consecutive patients were included over a 39-month period, and 715 (56.9%) were scheduled surgical patients. The observed hospital mortality was 28.6%. Two performance analyses were carried out: in the first analysis all patients were studied; and in the second, scheduled surgical patients were excluded in order to better compare CMM and general prognostic scores. The results of the two analyses were similar. Discrimination was good for all of the six studied models and best for Simplified Acute Physiology Score II and Acute Physiology and Chronic Health Evaluation III-J. However, calibration was uniformly insufficient (P < 0.001). General scores significantly underestimated mortality (in comparison with the observed mortality); this was in contrast to the CMM, which tended to overestimate mortality. CONCLUSION: None of the model scores accurately predicted outcome in the present group of critically ill cancer patients. In addition, there was no advantage of CMM over the other general models.

Staging of regional lymph nodes in melanoma patients by means of 99mTc-MIBI scintigraphy.

UNLABELLED: Most first relapses in patients with melanoma occur in regional lymph node basins. Such lesions are frequently diagnosed clinically during the first 2 y of follow-up. In the last few years, our group has been studying the usefulness of (99m)Tc-methoxyisobutylisonitrile (MIBI) scintigraphy in the evaluation of recurrent melanoma lesions. The aim of the present study was to prospectively evaluate the clinical value of (99m)Tc-MIBI scintigraphy in the diagnosis of subclinical nodal metastases. METHODS: We included 66 patients within 3 mo of melanoma diagnosis, with Breslow thickness > 1.0 mm, all treated with wide local excision of the primary lesion. When (99m)Tc-MIBI scanning was performed, 49 of them did not have evidence of nodal disease, and 17 had clinically questionable regional lymph node lesions. Planar images of lymph node regions were acquired 10 min after injection, using a dose of 740-1,110 MBq and a large-field-of-view gamma camera equipped with a low-energy high-resolution collimator. Scan findings were confirmed by pathology or by clinical follow-up (median, 35 mo). RESULTS: Thirty of 33 patients with regional lymph node metastases received a correct diagnosis, 14 with palpable lesions and 16 with nonpalpable lesions. In 3 cases that were initially (99m)Tc-MIBI negative, nodal metastases were found during follow-up. The following diagnostic values were calculated: sensitivity, 0.91 (95% confidence interval [CI], 0.75-0.98); specificity, 0.85 (95% CI, 0.67-0.94); likelihood ratio of a positive test, 6.0 (95% CI, 2.7-13.5); and likelihood ratio of a negative test, 0.11 (95% CI, 0.036-0.32). CONCLUSION: (99m)Tc-MIBI scanning may have a secondary role in the staging of regional lymph nodes in patients with clinically localized melanoma who are not good candidates for sentinel node biopsy.
