A PRECEDE-PROCEED approach in the advocacy for computer-based education on correct medical certification of cause of death among physician-learners

Objective@#Mortality data is a critical input to public health decision-making and planning. Yet, about 36% of underlying causes of death reported by physicians in 2018 are considered garbage codes, not useful in analyzing public health and mortality (PSA, 2018). We used the PRECEDE-PROCEED approach to develop, implement, and report an advocacy and education Project to improve training on medical certification of cause of death (MCCOD) among senior medical students and interns. @*Methods@#An MCCOD Instructional Design and eLearning course was introduced and validated in 33 medical education institutions. Lessons enhanced these education materials and are proposed for nationwide adoption. In the middle of the COVID-19 pandemic, the Project fast-tracked the training of physician-learners on the correct cause of death reporting and certification.@*Results@#Awareness of correct MCCOD and its personal and public health value reached at least 4000 learners, over a hundred medical faculty, and all deans of medical colleges in the Philippines.@*Conclusion@#The PRECEDE-PROCEED Model provided a clear and practicable framework for the advocacy and education efforts to train senior medical students and interns on MCCOD. It can similarly guide other medical education innovations by defining predisposing, enabling, and reinforcing factors then considering these factors for intervention strategies, implementation, process evaluation, outcome evaluations, and impact evaluations.

Sinonasal anatomy variations on CT scans of a sample of Filipino adults with chronic rhinosinusitis

Objective@#To determine the prevalence of sinonasal anatomic variations seen on paranasal sinus (PNS) CT scans of a sample of Filipino adults with chronic rhinosinusitis.@*Methods@#Design: Cross-sectional study Setting: Tertiary Government Training Hospital Participants: The PNS CT scans of 51 Filipino patients with chronic rhinosinusitis with and without nasal polyposis diagnosed at our outpatien Department of Otorhinolaryngology-Head and Neck Surgery between October 2015 to December 2020 were reviewed for the presence of sinonasal anatomic variants. The prevalence of the identified variants was calculated.@*Results@#The CT scans of 51 patients, 41 (80.4%) men and 10 (19.6%) women, were included. The median age was 48 years (Q25: 35, Q75: 56, IQR:21). The median Lund Mackay Score (LMS) was 15 (Q25: 12, Q75: 20, IQR:8). Majority (94%) had an LMS of ≥5. The most common anatomic variant in the study population was agger nasi (n=46/51, 90.2% present bilaterally) followed by uncinate process attachment to the lamina papyracea (n=90/102, 88.24%). The third to sixth most common findings were Keros type II classification (n=76/102, 74.51%), nasal septal deviation (n=35/51, 68.62%), optic nerve canal type 1 (n=67/102, 65.69%) and anterior ethmoid artery grade 1 (n=46/102, 45.1%), respectively. Less common variants were Onodi cell (n=13/51, 25.49% unilateral and n=10/51, 19.61% bilateral), Haller cell (n=8/51, 15.69% unilateral and n=1/51, 1.96% bilateral), supraorbital cell (n=4/51, 7.84% unilateral and n=4/51, 7.84% bilateral), middle turbinate concha bullosa (n=3/51, 5.88% unilateral and n=6/51, 11.76% bilateral), superior turbinate concha bullosa (n=2/51, 3.92% unilateral and n=1/51, 1.96% bilateral), pneumatized crista galli (n=2/51, 3.92%) and optic nerve dehiscence (n=1/51, 1.96% bilateral). @*Conclusion@#In the adult Filipino population with CRS sampled in this study, the six most common sinonasal anatomic variants were agger nasi, superior attachment of the uncinate process to the lamina papyracea, Keros type II classification, septal deviation, optic nerve canal type 1 and anterior ethmoid artery grade 1. Pre-operatively, the PNS CT scan of every patient must be meticulously evaluated for the sinonasal anatomic variants to avoid surgical complications.

“Lifestyle Redo” managing dyslipidemia as risk factor for cardiovascular disease in adults through lifestyle intervention

Background@#Cardiovascular disease (CVD) is a leading cause of death around the world including the Philippines. Dyslipidemia and lifestyle have been considered as important modifiable risk factors. Experts in the Philippines have recommended that among individuals with dyslipidemia, lifestyle modification should be advised regardless of their present condition or risk profile. However, a key limitation of the most recent guidelines is the lack of studies on lifestyle interventions involving Filipinos.@*Objective@#This study aimed to provide preliminary evidence for the use of a lifestyle medicine intervention program in the management of dyslipidemia as risk factor for cardiovascular disease.@*Methods@#This study employed a mixed method of quantitative and qualitative research designs. The tools used were selfadministered questionnaires, collecting and examining documents. Measures to improve validity in qualitative studies have also been employed such as respondent validation and rival explanation. Triangulation with the findings from the other qualitative methodologies was also employed. Ethical approval was granted.@*Results@#The first part of the study has a total of 66 participants who underwent a lifestyle intervention program in a single clinic, comprising of 26 male and 40 female subjects were selected through convenient sampling method. Around 50% of the participants were 40-59 years old, 42.4% were 30-39 years old, and only 7.6% were 60-89 years old. The knowledge of the respondents had an overall mean of 7.73 (SD=1.16) which is interpreted as high knowledge. The attitude of the respondents had a mean of 3.58 (SD=0.50) which is interpreted as very positive. The respondents also had a good lifestyle practice with overall mean of 2.76 (SD=0.49). The second part of the study consisted of eight participants with 3 males and 5 females who were chosen through purposive sampling. All participants experienced reduction of their LDL-C and total cholesterol levels after the 12-week lifestyle intervention. Two participants had increased triglyceride levels. The select group also showed reduction in the blood glucose levels and body mass index.@*Conclusion@#This study revealed that participants had good knowledge and attitude regarding cardiovascular diseases and its risk factors. Yet, there is still a high number of those who do not efficiently practice healthy lifestyle and diet. Additional information should be extracted to establish the dietary intake of participants which contributed to the increase in triglyceride levels of some select participants.

Predictors and outcomes of hospitalized COVID-19 patients with liver injury

Objective@#To determine incidence, predictors, and impact of liver injury among hospitalized COVID-19 patients@*Methods@#This is a retrospective cohort study of hospitalized COVID-19 patients at the University of the PhilippinesPhilippine General Hospital. Liver injury (LI) was defined as ALT elevation above institutional cut-off (>50 u/L) and was classified as mild (>1x to 3x ULN), moderate (>3x to 5x ULN), or severe (>5x ULN). Significant liver injury (SLI) was defined as moderate to severe LI. Univariate analysis of SLI predictors was performed. The impact of LI on clinical outcomes was determined and adjusted for known predictors -age, sex, and comorbidities.@*Results@#Of the 1,131 patients, 565 (50.04%) developed LI. SLI was associated with male sex, alcohol use, chronic liver disease, increasing COVID-19 severity, high bilirubin, AST, LDH, CRP, and low lymphocyte count and albumin. An increasing degree of LI correlated with ICU admission. Only severe LI was associated with the risk of invasive ventilation (OR: 3.54, p=0.01) and mortality (OR: 2.76, p=0.01). Severe LI, male sex, cardiovascular disease, and malignancy were associated with longer hospital stay among survivors.@*Conclusion@#The liver injury occurred commonly among COVID-19 patients and was associated with important clinicodemographic characteristics. Severe liver injury increases the risk of adverse outcomes among hospitalized patients.

Uso de partículas magnéticas en la purificación de anticuerpos IgM contra Taenia solium / Use of magnetic particles in the purification of IgM antibodies against Taenia solium

RESUMEN Se evaluó el uso de partículas magnéticas acopladas a proteína L para la concentración y purificación de anticuerpos monoclonales inmunoglobulina M (mIgM) contra Taenia solium. Se evaluaron tres métodos de concentración y diferentes tiempos de elución y se optimizó la proporción de partículas a la proporción de mIgM. Demostramos que: 1) con el uso partículas magnéticas no se requiere de una concentración previa de mIgM, lo que disminuye la manipulación de los anticuerpos y mejora la recuperación, 2) se puede omitir el uso de un tampón de unión, ya que el pH de la mayoría de los sobrenadantes de cultivo celular son neutros, y 3) se necesitan tiempos de elución más largos (~45 minutos) para aumentar la recuperación a un nivel mayor a 80%. El estudio demuestra que el uso de partículas magnéticas acopladas a proteína L es una herramienta simple y eficiente para la concentración y purificación de mIgM.

ABSTRACT The use of L protein coupled magnetic particles for the concentration and purification of immunoglobulin M (mIgM) monoclonal antibodies against Taenia solium was evaluated. Three concentration methods and different elution times were evaluated and the ratio of particles to the ratio of mIgM was optimized. It is demonstrated that: 1) with the use of magnetic particles, a previous concentration of mIgM is not required, which reduces the manipulation of the antibodies and improves the recovery, 2) the use of a binding buffer can be omitted, since the pH of most cell culture supernatants are neutral, and 3) longer elution times (~ 45 minutes) are needed to increase recovery to a level greater than 80%. The study demonstrates that the use of L protein-coupled magnetic particles is a simple and efficient tool for mIgM concentration and purification.

Data Sharing Statements for Clinical Trials: a Requirement of the International Committee of Medical Journal Editors / Declaración sobre compartir datos: un requerimiento del Comité Internacional de Editores de Revistas Médicas

El Comité Internacional de Editores de Revista Médicas (ICMJE) ha tomado la posición que el compartir los datos generados por los ensayos clínicos es una obligación ética, por cuanto los participantes en esos estudios se colocaron en riesgo al aceptar su inclusión. En esta editorial el ICMJE expresa que requerirá desde Julio 2018 que los manuscritos enviados a sus revistas deben incluir una declaración sobre compartir datos. A su vez, los ensayos clínicos que comiencen a enrolar pacientes a partir de Enero 2019, deben incluir un plan sobre compartir datos en el registro de tales ensayos. Se dan en esta declaración cuatro ejemplos de declaraciones sobre compartir datos, referidos a qué datos se compartirán, cuándo estarán disponibles y qué criterios de acceso se establecerán. El ICMJE visualiza un futuro cercano en el cual el compartir los datos será la norma, con el fin de maximizar el conocimiento ganado por los esfuerzos y sacrificios de los participantes.

Adherence To Acne Medication And Its Relation To Acne Severity And Quality Of Life

Background: Acne vulgaris is a chronic condition which commonly affects adolescents and exerts a psychological burden on its sufferers. Non-adherence to acne treatment is believed to be a major factor contributing to treatment failure. In this study, we characterize the profile of a non-adherent Asian acne patient, and evaluate the relationship between treatment adherence and acne severity and quality of life. Methods: A total of 53 acne patients were recruited from the Dermatology outpatient clinic of National University Hospital, Singapore, and followed up over a 3 month period in this prospective observational study. The Elaboration d’un outil d’evaluation de l’observance (ECOB) adherence assessment tool was used to assess adherence to acne treatment, and acne severity was evaluated using the US Food and Drug Administration Center 5-point Acne Severity Score (ASS). Results: Of the 53 study participants, 29 (54.7%) were non-adherent to acne treatment. There was no significant difference in gender, educational level or acne severity at time of presentation between adherent and non-adherent patients. Adherent patients had a significantly larger improvement in acne severity scores compared to non-adherent patients (change in ASS: -1.33 ± 0.64 vs -0.76 ± 0.83, p = 0.008), but this did not translate to a significant improvement in quality of life. Conclusion: Adherence to acne treatment was not associated with demographic characteristics or acne severity. Factors contributing to adherence to acne treatment are complex and multi-faceted, and individualized motivation and education of each patient may be the method of choice in encouraging treatment adherence.

The Practice of Physical Medicine and Rehabilitation in subSaharan Africa and Antarctica:A White Paper or a Black Mark? / 中国康复医学杂志

Objective: To explore the practice of PM&R in subSabaran Africa and Antarctica. Method: Medline searches, membership data searches, fax survey of medical schools, Internet searches, and interviews with experts. Result:The continents are dissimilar in terms of climate and govemment. However both Antarctica and subSaharan Africa have no PM&R training programs, no professional organizations, no specialty board requirements, and no practicing physicians in the field. Since there is no known disabled child on Antarctica and adults are airlifted to world-class health care, the consequences of this deficit are minimal there. However the 788,000,000 permanent residents of subSabaran Africa including approximately 78 million persons with disability are left unserved. Conclusion:Antarctica is doing fine. Africa is in a crisis. Local medical schools, hospitals doctors, and persons with disability; along with foreign volunteers, aid groups, and policymakers can impact the crisis. However govemment-specifically national ministries of health-is ultimately responsible for the health and wellbeing of citizens.

Synchronous surgical removal of suspicious ovarian metastases from colorectal cancer

Metastatic ovarian cancers occur in 3-8 percent of women undergoing surgical resection of a primary colorectal cancer. In this study we examined the characteristics of women with colorectal cancer for whom synchronous oophorectomy had been performed.In this cross-sectional study, records of patients with colorectal cancer from April 1991 through October 1999 who had undergone surgery for both colorectal cancer resection and oophorectomy for suspicious ovarian metastasis in the Cancer Institute, Imam Khomeini Medical Center, were reviewed. SPSS version 10 was used for statistical analysis.The studied cases [n= 82] comprised 44.1 percent of all recorded cases of women with colorectal cancer during this period [N= 186]. The mean age of our cases was 52.19 years. 54.9% of the studied women were in stage C of colorectal cancer. The commonest pathology of tumors was adenocarcinoma [89%]. Well differentiated carcinoma was observed in 43.9%, followed by moderately differentiated carcinoma in 37.8%, poorly differentiated in 12.2% and unspecified in 6.1%. 22 of our patients [26.8%] had gross abnormalities of ovaries at operation. In 13 cases [15.8% of our 82 studied cases and 6.99% of all 186 women with colorectal cancer], tumoral involvement of ovaries was proven through pathologic examination. 10 out of these 13 cases were among those with gross abnormalities of ovaries at operation [p= 0.048]. Among the 13 patients with ovarian metastasis, 11 cases [84.6%] were in stage C at operation [p= 0.02] and 7 [53.8%] had well differentiated carcinoma [p= 0.04].Patients with ovarian metastases of colorectal origin are generally peri- or post-menopausal. Like similar studies, in our setting, about 7 percent of all recorded female cases with colorectal cancer turned out to have ovarian metastases in surgical pathologic examination in fact, 15.8% of our 82 cases sustaining surgery for [[colorectal cancer and suspicious ovarian metastases]] proved to have ovarian metastases. We recommend that prophylactic oophorectomy be performed in postmenopausal women with advanced stage colorectal cancer or any other women with colorectal cancer with gross abnormality of the ovarian at operation

Beta-blockers in the treatment of heart failure / 第二军医大学学报

It is now clear that continued stimulation o f the neurohormonal system in heart failure (HF) has serious deleterious effects on the heart. The increase of circulating catecholamines exerts direct toxic ef fect on cardiac myocytes, increases membrane permeability and myocardial fibrosi s; lead to aggravation of HF. β-blockers are commonly used in the treatment of HF including propranolol, metoprolol, bisoprolol, bucindolol and carvedilol. These drugs are used in combination with ACEIs, digitalis and diuretics. Genera lly, the benefits of β-blockade therapy in HF include improving symptoms, decr easing morbidity, mortality, elevating need for hospitalization and quality of l ife. β- blockade therapy arrests and reverts LV remodeling and improves the ri sk of life threatening arrhythmias and sudden cardiac death. A few serious adver se effects include hypotension, heart blocks, bradycardia and fluid retention.
