Pesticide residues in boreal arable soils: Countrywide study of occurrence and risks.

Large volumes of pesticides are applied every year to support agricultural production. The intensive use of pesticides affects soil quality and health, but soil surveys on pesticide residues are scarce, especially for northern Europe. We investigated the occurrence of 198 pesticide residues, including both banned and currently used substances in 148 field sites in Finland. Results highlight that pesticide residues are common in the agricultural soils of Finland. A least one residue was found in 82% of the soils, and of those 32% contained five or more residues. Maximum total residue concentration among the conventionally farmed soils was 3043 µg/kg, of which AMPA and glyphosate contributed the most. Pesticide residues were also found from organically farmed soils, although at 75-90% lower concentrations than in the conventionally farmed fields. Thus, despite the application rates of pesticides in Finland being generally much lower than in most parts of central and southern Europe, the total residue concentrations in the soils occurred at similar or at higher levels. We also established that AMPA and glyphosate residues in soil are significantly higher in fields with cereal dominated rotations than in grass dominated or cereal-grass rotations. However, risk analyses for individual substances indicated low ecological risk for most of the fields. Furthermore, the total ecological risk associated with the mixtures of residues was mostly low except for 21% of cereal dominated fields with medium risk. The results showed that the presence of mixtures of pesticide residues in soils is a rule rather than an exception also in boreal soils. In highly chemicalized modern agriculture, the follow-up of the residues of currently used pesticides in national and international soil monitoring programs is imperative to maintain soil quality and support sustainable environment policies.

The outcome of 12-week corticosteroid therapy in COVID-19-related diffuse interstitial lung abnormalities.

INTRODUCTION: The efficacy of long-course corticosteroid therapy in treating COVID-19-related diffuse interstitial lung abnormalities (DILA) needs to be better understood. We aimed to investigate the benefits of 12-week corticosteroid treatment in COVID-19-related DILA by evaluating computed tomography (CT) lung severity scores. MATERIALS AND METHODS: This retrospective, single-centre observational study included patients aged 18 years or older admitted with moderate to severe COVID-19 pneumonia who received 12 weeks of oral prednisolone between January 2021 and December 2021. We recorded clinical parameters, baseline CT scores and post-treatment, modified Medical Research Council (mMRC) dyspnoea scale and pulmonary function tests. RESULTS: A total of 330 patients were analysed. The mean (standard deviation, SD) age was 54.6 (14.2) years, and 43% were females. Three-point nine per cent (3.9%) require noninvasive ventilation (NIV), while 14.6% require mechanical ventilation (MV). On follow-up at 12 weeks, the CT patterns showed improvement in ground-glass opacities, perilobular density and consolidation. There was an improvement in the mean (SD) CT score before and after prednisolone therapy, with values of 17.3 (5.3) and 8.6 (5.5), respectively (p<0.001). The median mMRC was 1 (IQR 0-1), and 98.8% had a radiological response. The common side effects of prednisolone therapy were weight gain (13.9%), hyperglycaemia (1.8%) and cushingoid habitus (0.6%). CONCLUSION: A 12-week treatment with prednisolone showed significant improvement in CT scores with minimal residual dyspnoea and was relatively safe. Longer duration of steroids may be beneficial in moderate to severe COVID-19- related DILA.

Effects of mixtures of herbicides on nutrient cycling and plant support considering current agriculture practices.

The use of mixtures of pesticides and consecutive pesticide applications challenge current regulations aimed at protecting ecosystem health due to unpredictable effects of complex and dynamic mixtures. In this study, we tested the ecotoxicological effects of mixtures of herbicides, applied following a real application scheme of soybean production on soil health in a mesocosm experiment. The experiment included two sequential applications; first, glyphosate + dicamba + clethodim, and 30 days later, flumioxazin + metolachlor. Commercial products were used at the recommended doses and at two other concentrations: half and double the recommended dose. Soybean plants were exposed to the herbicide-contaminated soil from the time of sowing to the beginning of pod formation. Half of the plants were harvested at the vegetative stage and the remaining plants at the reproductive stage to evaluate endpoints related to plant support and nutrient cycling. Plant biomass was significantly affected during the vegetative stage at the recommended and double the recommended dose, with the effects being mixture-dose dependent. Lower total and arbuscular colonization of mycorrhizas were also observed in double the recommended dose, and intermediate results were observed for the recommended dose. Nodule mass and phosphorous concentration in plants decreased with increasing herbicide doses. By the end of the experiment, nodule mass and total mycorrhizal colonization were low in the plants treated with double the recommended dose of herbicides. However, both endpoints reached similar values to the control at lower herbicide doses. Plant height and phenology were only lower at double the recommended dose during the experiment. The use of non-standard endpoints evidenced that important soil functions were transiently or permanently affected, while the realistic application scheme accounted for the impact of the management practice currently used. Pesticide risk assessment should therefore, incorporate both issues to effectively protect the ecosystems.

Prevalence and determinants of chronic respiratory diseases in adults in rural Sudan.

BACKGROUND: Chronic respiratory diseases (CRDs) greatly contribute to worldwide mortality. Despite new data emerging from Africa, prevalence estimates and determinants of CRDs in rural settings are limited. This study sought to extend the existing research conducted in urban Sudan by conducting a rural comparison.METHODS: Participants aged ≥18 years (n = 1,850), living in rural Gezira State completed pre-and post-bronchodilator spirometry and a questionnaire. Prevalence of respiratory symptoms and spirometric abnormalities were reported. Regression analyses were used to identify risk factors for CRDs.RESULTS: Prevalence of chronic airflow obstruction (CAO) was 4.1% overall and 5.5% in those aged ≥40 years. Reversibility was seen in 6.4%. Low forced vital capacity (FVC) was seen in 58.5%, and at least one respiratory symptom was present in 40.7% of the participants. CAO was more common among people aged 60-69 years (OR 2.07, 95% CI 1.13-3.82) and less common among highly educated participants (OR 0.50, 95% CI 0.27-0.93). Being underweight was associated with lower FVC (OR 3.07, 95% CI 2.24-4.20).CONCLUSIONS: A substantial burden of CRD exists among adults in rural Sudan. Investment in CRD prevention and management strategies is needed.

Updating a Healthcare System-wide Clinical Pathway for Managing Chest Pain and Acute Coronary Syndromes.

Clinical pathways are useful tools for conveying and reinforcing best practices to standardize care and optimize patient outcomes across myriad conditions. The NewYork-Presbyterian Healthcare System has utilized a clinical chest pain pathway for more than 20 years to facilitate the timely recognition and management of patients presenting with chest pain syndromes and acute coronary syndromes. This chest pain pathway is regularly updated by an expanding group of key stakeholders, which has extended from the Columbia University Irving Medical Center to encompass the entire regional healthcare system, which includes 8 hospitals. In this 2023 update of the NewYork-Presbyterian clinical chest pain pathway, we present the key changes to the healthcare system-wide clinical chest pain pathway.

Twenty Years of an Institutional Chest Pain Pathway: What's Come and What's Yet to Come.

Acute coronary syndromes (ACS) remain one of the leading causes of cardiovascular morbidity and mortality in the United States and around the world. Because of the acute nature of ACS presentations, timely identification, risk stratification, and intervention are of the utmost importance. Twenty years ago, we published the first iteration of our institutional chest pain clinical pathway in this journal, which separated patients presenting with chest pain into one of the 4 levels of decreasing acuity, with associated actions and interventions for providers based on the level. This chest pain clinical pathway has undergone regular review and updates under a collaborative team of cardiologists, emergency department physicians, cardiac nurse practitioners, and other associated stakeholders in the treatment of patients presenting with chest pain. This review will discuss the key changes that our institutional chest pain algorithm has undergone over the last 2 decades and what the future holds for chest pain algorithms.

Prevalence and determinants of chronic respiratory diseases in adults in Sudan.

BACKGROUND: Chronic respiratory diseases (CRDs) are considered a significant cause of morbidity and mortality worldwide, although data from Africa are limited. This study aimed to determine the prevalence and determinants of CRDs in Khartoum, Sudan.METHODS: Data were collected from 516 participants aged ≥40 years, who had completed a questionnaire and undertook pre- and post-bronchodilator spirometry testing. Trained field workers administered the questionnaires and conducted spirometry. Survey-weighted prevalence of respiratory symptoms and spirometric abnormalities were estimated. Regression analysis models were used to identify risk factors for chronic lung diseases.RESULTS: Using the Third National Health and Nutrition Examination Survey, 1988-1994 (NHANES III) reference equations, the prevalence of chronic airflow obstruction (CAO) was 10%. The main risk factor was older age, 60-69 years (OR 3.16, 95% CI 1.20-8.31). Lower education, high body mass index and a history of TB were also identified as significant risk factors. The prevalence of a low forced vital capacity (FVC) using NHANES III was 62.7% (SE 2.2) and 11.3% (SE 1.4) using locally derived values.CONCLUSION: The prevalence of spirometric abnormality, mainly low FVC, was high, suggesting that CRD is of substantial public health importance in urban Sudan. Strategies for the prevention and control of these problems are needed.

ENPP4 and HOXA3 as potential leukaemia stem cell markers in acute myeloid leukaemia.

INTRODUCTION: Acute myeloid leukaemia (AML) is a heterogeneous malignant disease with a high degree of treatment failure using chemotherapy. Leukaemia stem cells (LSCs) are CD34+CD38- early progenitors associated with poor prognosis in AML. A unique LSC phenotype that excludes rare normal haematopoietic stem cells (HSC) is still elusive. This study aimed to determine expression of selected potential LSC markers in normal and leukaemic myeloid cells and correlate prognosis in AML patients. MATERIALS AND METHODS: Flow cytometry and RT-qPCR measured expressions of ALDH, IL3RA/CD123, CLEC12A/CLL-1/CD371, HOXA3 and ENPP4. Normal cord blood (n=3) and blood monocytes (n=5) represented HSC and mature cells, respectively. Myeloid leukaemia cell lines (THP-1, KG-1a, K562 and HL-60) represented progenitor cells at various stages of maturation. AML samples included chemo-resistant (n=8), early relapse (n=2) and late relapse (n=18). RESULTS: Combining protein/gene expressions, CD34+CD38- was a feature of immature cells seen in cord blood, KG-1a, and K562 but not more mature cells (blood monocytes and HL-60). Normal cells expressed CD371 while mature cells (blood monocytes and HL-60) lacked CD123. ENPP4 was not expressed on normal cells while HOXA3 was expressed only on cord blood and THP-1. In AML, CD123, HOXA3, ENPP4 (but not CD371) were significantly increased in the CD34+CD38- fraction of chemo-resistant patients while ALDH was associated with chemo-resistance. CONCLUSION: CD34+CD38- presented an immature phenotype and with ALDH were associated with poor prognosis. CD123, HOXA3 and ENPP4 further enriched the LSC population. ENPP4 has not been reported and has the advantage of not being expressed on HSC and normal monocytes.

Chronic respiratory disease in adult outpatients in three African countries: a cross-sectional study.

BACKGROUND: The greatest burden of chronic respiratory disease is in low- and middle-income countries, with recent population-based studies reporting substantial levels of obstructive and restrictive lung function.OBJECTIVE: To characterise the common chronic respiratory diseases encountered in hospital outpatient clinics in three African countries.METHODS This was a cross-sectional study of consecutive adult patients with chronic respiratory symptoms (>8 weeks) attending hospital outpatient departments in Ethiopia, Kenya and Sudan. Patients were assessed using a respiratory questionnaire, spirometry and chest radiography. The diagnoses of the reviewing clinicians were ascertained.RESULT: A total of 519 patients (209 Kenya, 170 Ethiopia, 140 Sudan) participated; the mean age was 45.2 years (SD 16.2); 53% were women, 83% had never smoked. Reviewing clinicians considered that 36% (95% CI 32-40) of patients had asthma, 25% (95% CI 21-29) had chronic bronchitis, 8% (95% CI 6-11) chronic obstructive pulmonary disease (COPD), 5% (95% CI 4-8) bronchiectasis and 4% (95% CI 3-6) post-TB lung disease. Spirometry consistent with COPD was present in 35% (95% CI 30-39). Restriction was evident in 38% (95% CI 33-43). There was evidence of sub-optimal diagnosis of asthma and COPD.CONCLUSION: In Ethiopia, Kenya and Sudan, asthma, COPD and chronic bronchitis account for the majority of diagnoses in non-TB patients with chronic respiratory symptoms. The suboptimal diagnosis of these conditions will require the widespread use of spirometry.

Biomechanics of Different Types of PEEK as Implant Materials for Implant-Retained Mandibular Overdentures.

PURPOSE: To evaluate the biomechanical behavior of different types of PEEK as implant materials for mandibular implant-retained overdentures. MATERIALS & METHODS: Virtual models of mandibular overdentures retained by two interforaminal implants were simulated. In each model, one implant material was assumed resulting in four models; titanium, carbon-reinforced PEEK, ceramic-filled PEEK and unfilled PEEK models. Unilateral vertical and oblique loads were applied separately. Von-Mises stresses and maximum equivalent strain values were computed. RESULTS: All PEEK implant models induced higher stresses in the cervical portion of peri-implant bone compared to the titanium model. A more homogenous stress distribution pattern along the whole length of the titanium implants was observed compared to PEEK implants. The highest amount of strain values was recorded in the unfilled PEEK implants. CONCLUSIONS: Titanium remains to be the most optimum material for dental implants. Unfilled and ceramic filled PEEK might not be recommended as a dental implant material due to the high stresses generated within the implant bodies and cervical part of peri-implant bone under oblique load which might contribute to an increased probability of implant body fracture and marginal bone loss.

Mode of bond failure between 3D-printed denture teeth and printed resin base material: effect of fabrication technique and dynamic loading. An in-vitro study.

PURPOSE: To evaluate the failure load of 3D-printed denture resin material and teeth before and after dynamic loading. MATERIALS AND METHODS: A total of 40 specimens were fabricated following ISO/TS 19736 and were divided into two equal groups. In the test group, the cylindrical base and denture teeth were 3D printed separately and then luted together. In the control group, the specimens were fabricated from conventional heat-cured polymethyl methacrylate (PMMA) and commercially available denture teeth using the compression-molding technique. Ten specimens from each group were subjected to dynamic load of 50 N for 250,000 cycles in a chewing simulator. All specimens were subjected to static load of 50 N using Instron machine with a crosshead speed of 1 mm/minute until fracture. The fractured surfaces were analyzed using field emission scanning electron microscopy. The failure loads were calculated and compared using analysis of variance (P < .05). RESULTS: All specimens survived the loading, undergoing 250,000 cycles without fracture. The mean failure load was influenced by fabrication technique and was significantly higher for the 3D-printed test group (P = .028). 3D-printed teeth showed a mixed mode of fracture, whereas in the control group, the specimens showed cohesive fracture within the teeth. CONCLUSION: The fabrication technique has an influence on the mode of failure between acrylic teeth and resin base material. Cohesive failure in teeth was predominant in the conventional group, suggesting possibly higher bond strength between the teeth and resin base in this group. The observed failure modes reveal that both fabrication techniques exhibited satisfactory bond strength. Chewing simulation did not significantly influence the bond strength of any of the tested groups.

Does build angle have an influence on surface roughness of anterior 3D-printed restorations? An in-vitro study.

PURPOSE: To evaluate the effect of build direction on the surface roughness (Ra) of stereolithography (SLA) printed full-coverage anterior dental restorations before and after surface polishing. MATERIALS AND METHODS: A total of 45 full-coverage dental restorations were 3D printed using the SLA additive manufacturing technique. Five groups were defined based on the build angles: 90, 120, 135, 150, and 180 degrees. The Ra was measured with the contact profilometer to evaluate the arithmetic average of the absolute Ra value on the labial surface before and after polishing procedures. Data were analyzed using two-way ANOVA, and statistical significance was set at α = .05. RESULTS: The highest Ra was recorded in specimens printed with the 90-degree build angle, whereas the lowest values were recorded in specimens printed with the 180-degree build angle (P = .000). In all groups, the Ra values measured after polishing were significantly lower than prepolished values (P = .000), with no difference among the different build angles. CONCLUSION: Build angle significantly influenced the Ra of the SLA-printed full-coverage restorations. Polishing minimized the effect of build angle on the Ra. The 180-degree build angle is recommended when SLA printing an anterior restoration, as it provides the lowest Ra values and also requires a minimal support area and minimal number of support structures.

Rule Out Acute Kidney Injury in the Emergency Department With a Urinary Dipstick.

INTRODUCTION: The identification of acute injury of the kidney relies on serum creatinine (SCr), a functional marker with poor temporal resolution as well as limited sensitivity and specificity for cellular injury. In contrast, urinary biomarkers of kidney injury have the potential to detect cellular stress and damage in real time. METHODS: To detect the response of the kidney to injury, we have tested a lateral flow dipstick that measures a urinary protein called neutrophil gelatinase-associated lipocalin (NGAL). Analysis of urine was performed in a prospective cohort of 479 patients (final cohort N = 426) entering an emergency department in New York City and subsequently admitted for inpatient care. RESULTS: Colorimetric development had high interrater reliability (88% concordance rate) and correlated with traditional enzyme-linked immunosorbent assay (ELISA) measurements (ρ = 0.732, P < .0001). Of the 14% of the cohort who met Acute Kidney Injury Network (AKIN) SCr criteria for acute kidney injury (AKI), 67% demonstrated transient (<2 days) and 33% demonstrated sustained (>2 days) elevation of SCr. Comparing the outcomes of patients with sustained versus transient or undetectable changes in SCr revealed that the urinary NGAL (uNGAL) dipstick had high specificity and negative predictive value (NPV) (high- vs. low-intermediate readings, sensitivity = 0.55, specificity = 0.91, positive predictive value = 0.24, NPV = 0.97, χ2 = 20.39, P < 0.001). CONCLUSION: We show that the introduction of a bedside uNGAL dipstick permits accurate triage by identifying individuals who do not have tubular injury. In an era of shortening length of stay and rapid decisions based on isolated SCr measurements, real-time exclusion of kidney injury by a dipstick will be particularly useful to overcome the retrospective, insensitive, and nonspecific attributes of SCr.

Clinical Pathway for Management of Suspected or Positive Novel Coronavirus-19 Patients With ST-Segment Elevation Myocardial Infarction.

Novel coronavirus-19 disease (COVID-19) is an escalating, highly infectious global pandemic that is quickly overwhelming healthcare systems. This has implications on standard cardiac care for ST-elevation myocardial infarctions (STEMIs). In the setting of anticipated resource scarcity in the future, we are forced to reconsider fibrinolytic therapy in our management algorithms. We encourage clinicians to maintain a high level of suspicion for STEMI mimics, such as myopericarditis which is a known, not infrequent, complication of COVID-19 disease. Herein, we present a pathway developed by a multidisciplinary panel of stakeholders at NewYork-Presbyterian/Columbia University Irving Medical Center for the management of STEMI in suspected or confirmed COVID-19 patients.

Conscious Proning: An Introduction of a Proning Protocol for Nonintubated, Awake, Hypoxic Emergency Department COVID-19 Patients.

The novel coronavirus, or COVID-19, has rapidly become a global pandemic. A major cause of morbidity and mortality due to COVID-19 has been the worsening hypoxia that, if untreated, can progress to acute respiratory distress syndrome (ARDS) and respiratory failure. Past work has found that intubated patients with ARDS experience physiological benefits to the prone position, because it promotes better matching of pulmonary perfusion to ventilation, improved secretion clearance, and recruitment of dependent areas of the lungs. We created a systemwide multi-institutional (New York-Presbyterian Hospital enterprise) protocol for placing awake, nonintubated, emergency department patients with suspected or confirmed COVID-19 in the prone position. In this piece, we describe the background literature and the approach we have taken at our institution as we care for a high burden of COVID-19 cases with respiratory symptoms.

An Updated Healthcare System-Wide Clinical Pathway for Managing Patients With Chest Pain and Acute Coronary Syndromes.

Clinical pathways reinforce best practices and help healthcare institutions standardize care delivery. The NewYork-Presbyterian/Columbia University Irving Medical Center has used such a pathway for the management of patients with chest pain and acute coronary syndromes for almost 2 decades. A multidisciplinary panel of stakeholders serially updates the algorithm according to new data and recently published guidelines. Herein, we present the 2019 version of the clinical pathway. We explain the rationale for changes to the algorithm and describe our experience expanding the pathway to all the 8 affiliated institutions within the NewYork Presbyterian healthcare system.

Chronic respiratory disease in adults treated for tuberculosis in Khartoum, Sudan.

Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB-associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98-14.90, P < 0.001) and the presence of chronic airflow obstruction (OR 12.4, 95%CI 1.56-98.40, P = 0.02) were both strongly associated with a past history of PTB after adjusting for potential confounders. Conclusion: The clinical features of CRDs are strongly associated with past history of PTB. An integrated approach to improve the management of these common conditions should be considered. Contexte : Les maladies respiratoires chroniques (MRC) sont à l'origine d'une morbidité et d'une mortalité considérables dans le monde. Bien que l'épidémie mondiale des MRC entre en conflit avec l'épidémie de tuberculose (TB) dans de nombreux pays à revenu faible ou moyen, le risque de MRC associée à la TB n'est pas bien décrit dans les pays durement frappés par la TB. Méthodes : Nous avons recruté 136 patients ayant des antécédents de tuberculose pulmonaire (TBP) à frottis positif dans le service de pneumologie du Centre Hospitalier Universitaire Omdurman à Khartoum, Soudan, et 136 témoins de la communauté, appariés sur l'âge et le sexe, entre le 28 juillet 2013 et le 30 décembre 2013. Les données ont été recueillies grâce à des questionnaires standardisés ainsi qu'à une spirométrie avant et après bronchodilatateur. Résultats : L'âge moyen des cas et des témoins a été de 44,0 ans (DS 8,5) et 44,5 ans (DS 8,61), respectivement, avec 27,2% de femmes dans les deux groupes. Des symptômes respiratoires chroniques comme une toux chronique (OR 6,67 ; IC95% 2,98-14,90 ; P < 0,001) et la présence d'une obstruction chronique des voies aériennes (OR 12,39 ; IC%95 1,56-98,40 ; P = 0,02) ont été tous deux fortement associés à des antécédents de TBP après ajustement sur les facteurs de confusion potentiels. Conclusion : Les caractéristiques cliniques des MRC sont fortement associées à des antécédents de TBP. Une approche intégrée visant à améliorer la prise en charge de ces pathologies fréquentes devrait être envisagée. Marco de referencia: La enfermedad pulmonar crónica (EPC) es una causa importante de morbilidad y mortalidad. Aunque la epidemia mundial de EPC rivaliza con la epidemia de tuberculosis (TB) en muchos entornos de países con bajos y medianos recursos, el riesgo de aparición de EPC asociado con la TB se ha descrito cabalmente en los países con una alta carga de morbilidad por TB. Métodos: Entre el 28 de julio y el 30 de diciembre del 2013, participaron en el estudio 136 pacientes con antecedente de tuberculosis pulmonar (TBP) y baciloscopia positiva del esputo que habían recibido tratamiento en el consultorio de neumología del Hospital Universitario Omdurman de Jartún, en Sudán, y 136 testigos sanos de la comunidad, emparejados en función de la edad y el sexo. Se recogieron datos mediante cuestionarios normalizados y se practicó una espirometría antes y despuès una prueba de broncodilatación. Resultados: El promedio de la edad en el grupo de los casos fue 44,0 (desviación estándar 8,5 años) y en el grupo de testigos fue 44,5 años (8,6 años); la proporción de mujeres en ambos grupos fue 27,2%. Se observó una fuerte asociación entre la presencia de síntomas respiratorios crónicos como la tos (OR 6,67; IC95% 2,98-14,90; P < 0,001) y la presencia de obstrucción crónica al flujo en las vías respiratorias (OR 12,39; IC95% 1,56-98,40; P = 0,02) en las personas con antecedente de TBP, una vez corregidos los posibles factores de confusión. Conclusión: La presencia de rasgos clínicos de EPC exhibe una fuerte correlación con el antecedente de TBP. Es preciso considerar la posibilidad de aplicar un enfoque integrado con el fin de mejorar la atención de ambas enfermedades tan frecuentes.

Malaysian private general practitioners' views and experiences on continuous professional development: A qualitative study.

INTRODUCTION: Continuous professional development (CPD) is an important aspect of a medical practitioner's career. AIMing to be at par with other developed countries for high quality of professional practice, Malaysia is planning to implement compulsory CPD for the doctors. AIM: The aim of the study was to explore the private general practitioners' (GPs) views, experiences and needs regarding CPD programme in the primary care service. METHODS: This study used a qualitative methodology. Seven semi-structured interviews and three focus group discussions were conducted with private general practitioners from an urban area of Malaysia between January and December 2012. An interview topic guide was developed based on literature review and researchers' discussions and it was used to guide the interviews. All the interviews were audio-recorded, transcribed verbatim and the transcripts formed the data for analysis using the thematic approach. RESULTS: GPs undertook a wide range of CPD programmes to keep up with medical advances, meet patients' expectations and improve financial rewards. Conferences, lectures and online recourses were the most mentioned methods of keeping updated. Some of the GPs felt that peer motivation and networking seem to motivate and facilitate participation in CPD programmes. However, they were wary of the validity and relevance of some CPD programmes, particularly those related to pharmaceutical industry. Although the participants agreed to the new mandatory CPD regulation, they voiced concerns on how it would be implemented and wished for a more effective method of monitoring. CONCLUSIONS: Organised peer support and relevant CPD content may improve GP participation in CPD but adequate regulatory measure should be in place to monitor the CPD activities.
