Data on the accuracy of Xpert® MTB/RIF (Xpert) assay in detecting TB in lymph node aspirates in Papua New Guinea (PNG) is scanty. This study evaluated Xpert performance in diagnosing tuberculous lymphadenitis (TBLN) using lymph node needle aspirates at the Port Moresby General Hospital (PMGH). The objective of the study was to compare Xpert accuracy to acid fast bacilli (AFB) microscopy, cytomorphology, a composite reference test (CRS) and culture. A total of 107 eligible subjects were recruited out of 1080 clinic attendees. Results showed Xpert detected significantly more cases of TBLN than AFB microscopy (66 vs 35; p=0.001). Compared to AFB microscopy Xpert had a sensitivity of 45.4% (95% CI 33.1-58.1), specificity of 87.8% (95% CI 73.8-95.9), positive predictive value (PPV) of 85.7% (95% CI 71.6-93.4) and negative predictive value (NPV) of 50.0%% (95% CI 43.8-56.1). There was no difference between Xpert and cytomorphology (66 vs 60; p=0.5). Compared to cytomorphology Xpert had a sensitivity of 71.6% (95% CI 58.5-82.5), specificity of 51.1% (95% CI 35.7-66.3), PPV of 66.1% (95% CI 58.2-73.2) and NPV of 57.5% (95% CI 45.2-68.9). There was no difference between Xpert and CRS (66 vs 71; p=0.6). Compared to CRS Xpert had a sensitivity of 76.0% (95% CI 64.4- 85.3), specificity of 66.6% (95% CI 49.0-81.4), PPV of 81.8% (95% CI 73.5-87.9) and NPV of 58.4% (95% CI 46.7-69.4). Culture was completed on 24 subjects with positive isolates in 14 giving a culture yield of 58.3%. Of the 24 subjects, Xpert was positive in 21 subjects. There was no difference between Xpert and culture (21 vs 14; p=0.8). Compared to culture Xpert had a sensitivity of 100.0% (95% CI 76.8-100.0), specificity of 30.0% (95% CI 6.6-65.2), PPV of 66.6% (95% CI 57.1-75) and NPV of 100.0%. The results suggest Xpert is more sensitive than AFB microscopy but comparable to cytomorphology and CRS for TBLN diagnosis in the PNG context. Xpert can be used for diagnosing TBLN at PMGH

SUMMARY Patients with a clinical diagnosis of tuberculous lymphadenitis (TBLN) undergoing fine needle aspiration (FNA) biopsy at Port Moresby General Hospital (PMGH) were recruited in a pilot study to compare Xpert® MTB/RIF (Xpert) with microscopy and cytology. From a total of 1080 patients attending the FNA clinic during the study period 107 were recruited, of whom 105 were analysed. Xpert detected Mycobacterium tuberculosis in 65/105 subjects (62%), acid-fast bacilli (AFB) were found in 35/105 (33%) and cytology was positive in 59/105 (56%). 3 of 7 samples unsuitable for microscopy and 9 of the 28 cases (32%) initially classified as non-TBLN were Xpert positive. Xpert was comparable to cytology but more sensitive than microscopy. Xpert also detected multidrug-resistant tuberculosis (MDR-TB) TBLN cases. The results demonstrated that FNA samples are suitable for Xpert analysis at PMGH to diagnose TBLN, which has the added advantage of detecting MDR-TB.

Objective: To determine the effect of pre-operative isometric exercise (PIE) on vascular caliber of pediatric chronic kidney disease (CKD) Stage 2-5D patients. Materials and Methods: This is a single-blind, randomized, single-center trial of 28 CKD patients. Fourteen participants allocated in the intervention group (PIE) were provided with a handgrip device and performed handgrip exercise consisting of two sets of 30 contractions daily while another 14 participants did not perform the exercise and were considered as controls (NE). For both groups, Duplex Ultrasonography was performed at baseline, four and eight weeks post-intervention. Results: Twenty-four CKD patients were included and analyzed. The mean age was 15.8 (+/- 1.9) years. There were 16 (66.7%) females and eight (33%) Males, 10 (41.7%) underweight (<18 kg/m2 ), 23 (95.8%) right-handed, 12 (50%) with Chronic Glomerulonephritis, and 10 (41.7%) with stage 2 CKD. Both the intervention and control group revealed a statistically significant increase in the caliber of the non-dominant cephalic (ante-cubital) vein at four- and eight-weeks post-intervention. Conclusion PIE might not significantly impact vessel diameter in pediatric CKD population as compared to adult CKD patients. Further studies on reliability of ultrasonography of blood vessels utilizing a larger sample size and more controlled milieu are recommended.

The pattern of antibiotics prescribed to patients with peripheral lymphadenopathy was assessed and compared with existing standard treatment guidelines (STGs) in Papua New Guinea (PNG). Information was obtained from patients referred to the Port Moresby General Hospital for fine needle aspiration biopsy by interviewing patients and reviewing patients’ clinic attendance record books and referral letters. Of the 107 patients recruited for the study, 51 (48%) were prescribed antibiotics and, of these, prescription data were obtained from 40 (78%). Amoxycillin, which is recommended as a first-line antibiotic for peripheral lymphadenopathy in PNG STGs, was prescribed in only 18/40 patients (45%). There was also high variability in other antibiotic selection, antibiotic combinations and treatment duration. The results highlight a need for ongoing training on rational antibiotic prescribing.

PURPOSE: A cross sectional descriptive study, which involved government hospitals and health clinics from Peninsular Malaysia sought to identify the continuing professional education (CPE) needs and their readiness for E-learning. This paper focuses on the first phase of that study that aimed to determine the factors that influence nurses' participation in CPE. METHODS: Multistage cluster sampling was used to recruit 1,000 nurses randomly from 12 hospitals and 24 health clinics from four states in Peninsular Malaysia who agreed to be involved. The respondent rate was 792 (79.2%), of which 562 (80%) had participated in CPE in the last 12 months. RESULTS: Findings suggested that updating knowledge and providing quality care are the most important factors that motivate participation in CPE, with respective means of 4.34 and 4.39. All the mean scores for educational opportunity were less than 3.0. Chi-square tests were used to test the association of demographic data and CPE participation. All demographical data were significantly associated with CPE participation, except marital status. CONCLUSIONS: Implementation of mandatory CPE is considered an important measure to increase nurse's participation in CPE. However, effective planning that takes into consideration the learning needs of nurses is recommended.

Background: The medical curriculum is one of the most stressful academic curricula worldwide. Studies indicate that great levels of stress, that encompass academics to personal life, may be connected to a number of worrying statistics for the mental health of Philippine medical students. Objectives: To develop a validated stressor-coping style scale for students in a public medical school. Methods: The study employed a sequential mixed-methods design. An open-ended questionnaire was used to determine the common stressors and coping styles through convenience sampling. A scale was constructed from this data and was statistically tested for concurrent validity and reliability from a random sample. Results: Following thematic analysis, an initial six stressor domains and eleven coping mechanisms were identified. However, after item analysis and principal component analysis of responses, the scale was transformed to seven stressor domains and five coping mechanism domains. All of which are deemed internally consistent (α>0.6). Scores from the scale were also convergent with the scores of Brief COPE (r=0.5 to 0.9). Conclusions The developed stressor-coping style scale for medical students is a reliable and valid tool for Filipino medical students in a public medical school.

BACKGROUND

The medical curriculum is one of the most stressful academic curricula worldwide. Studies indicate that great levels of stress, that encompass academics to personal life, may be connected to a number of worrying statistics for the mental health of Philippine medical students.

To develop a validated stressor-coping style scale for students in a public medical school.

The study employed a sequential mixed-methods design. An open-ended questionnaire was used to determine the common stressors and coping styles through convenience sampling. A scale was constructed from this data and was statistically tested for concurrent validity and reliability from a random sample.

Following thematic analysis, an initial six stressor domains and eleven coping mechanisms were identified. However, after item analysis and principal component analysis of responses, the scale was transformed to seven stressor domains and five coping mechanism domains. All of which are deemed internally consistent (α>0.6). Scores from the scale were also convergent with the scores of Brief COPE (r=0.5 to 0.9).

The developed stressor-coping style scale for medical students is a reliable and valid tool for Filipino medical students in a public medical school.

OBJECTIVES: The study aims to assess the dietary habits and nutritional knowledge of selected Philippine national combat sports athletes and determine the correlation of demographics and sources of nutrition information with participants' dietary habits and nutrition knowledge. METHODS: This cross-sectional study included assessing boxing and taekwondo Philippine national athletes using the Dietary Habits and Nutrition Knowledge Questionnaire: Filipino Version. Data were analyzed using descriptive statistics and inferential statistics between sports comparison and exploratory correlation and regression analyses. Alpha was set at 0.05. RESULTS: A total of 44 participants aged 21+ 3.4 years were able to participate in the study. Responses revealed that 69.44% have fair dietary habits and 73.54% have good nutritional knowledge. Results indicated no significant difference between the two sports in dietary habits and nutritional knowledge (p>0.05). Further analyses revealed that years in playing (r= 0.32, p= 0.04), and sources of nutrition information, precisely strength and conditioning coach (r= 0.36, p= 0.02), and peers (r= 0.39, p= 0.01) have a significant correlation with good dietary habit and nutritional knowledge, respectively. CONCLUSION Overall, Filipino national athletes of boxing and taekwondo have fair dietary habits and sound nutritional knowledge. Furthermore, nutritional knowledge sources are possible relevant factors that may affect the dietary habits and nutritional knowledge of combat sports athletes.

Objective: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), primarily targets the respiratory system. This study describes the characteristics associated with mortality among patients infected with SARS-CoV-2 at a single hospital in Baguio City, Philippines. Methods: We reviewed medical records (including history, laboratory results and treatment regimen) of 280 confirmed COVID-19 patients admitted to a single hospital during March–October 2020. Clinical characteristics and outcomes (frequency and type of complication, recovery rate and mortality) were evaluated. Multiple logistic regression was used to analyse factors associated with mortality. Results: The mean age of COVID-19 patients was 48.4 years and the female-to-male ratio was 1.8:1. Hypertension, cardiovascular disease (CVD) and diabetes were the most frequent comorbidities reported. Common presenting symptoms were respiratory and constitutional, with 41% of patients not reporting symptoms on admission. Patients with moderate, severe and critical disease comprised 45%, 8% and 4%, respectively. A total of 15% had complications, health care-associated pneumonia being the most frequent complication. The recovery rate was 95%; 5% of patients died, with multiorgan failure being the most common cause. The presence of CVD, chronic kidney disease, prolonged prothrombin time and elevated lactate dehydrogenase (LDH) were associated with mortality. Discussion Most COVID-19 patients in our population had asymptomatic to moderate disease on admission. Mortality from COVID-19 was associated with having CVD, chronic kidney disease, elevated LDH and prolonged prothrombin time. Based on these results, we emphasize that people should take all necessary precautions to avoid infection with SARS-CoV-2.

Objective: The mandible is the most common fractured craniofacial bone of all craniofacial fractures in the Philippines, with the mandibular body as the most involved segment of all mandibular fractures. To the best of our knowledge, there are no existing guidelines for the diagnosis and management of mandibular body fractures in particular. General guidelines include the American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAOHNSF) Resident Manual of Trauma to the Face, Head, and Neck chapter on Mandibular Trauma, the American Association of Oral and Maxillofacial Surgeons (AAOMS) Clinical Practice Guidelines for Oral and Maxillofacial Surgery section on the Mandibular Angle, Body, and Ramus, and a 2013 Cochrane Systematic Review on interventions for the management of mandibular fractures. On the other hand, a very specific Clinical Practice Guideline on the Management of Unilateral Condylar Fracture of the Mandible was published by the Ministry of Health Malaysia in 2005. Addressing the prevalence of mandibular body fractures, and dearth of specific guidelines for its diagnosis and management, this clinical practice guideline focuses on the management of isolated mandibular body fractures in adults. Purpose: This guideline is meant for all clinicians (otolaryngologists – head and neck surgeons, as well as primary care and specialist physicians, nurses and nurse practitioners, midwives and community health workers, dentists, and emergency first-responders) who may provide care to adults aged 18 years and above that may present with an acute history and physical and/or laboratory examination findings that may lead to a diagnosis of isolated mandibular body fracture and its subsequent medical and surgical management, including health promotion and disease prevention. It is applicable in any setting (including urban and rural primary-care, community centers, treatment units, hospital emergency rooms, operating rooms) in which adults with isolated mandibular body fractures would be identified, diagnosed, or managed. Outcomes are functional resolution of isolated mandibular body fractures; achieving premorbid form; avoiding use of context-inappropriate diagnostics and therapeutics; minimizing use of ineffective interventions; avoiding co-morbid infections, conditions, complications and adverse events; minimizing cost; maximizing health-related quality of life of individuals with isolated mandibular body fracture; increasing patient satisfaction; and preventing recurrence in patients and occurrence in others. Action Statements The guideline development group made strong recommendationsfor the following key action statements: (6) pain management- clinicians should routinely evaluate pain in patients with isolated mandibular body fractures using a numerical rating scale (NRS) or visual analog scale (VAS); analgesics should be routinely offered to patients with a numerical rating pain scale score or VAS of at least 4/10 (paracetamol and a mild opioid with or without an adjuvant analgesic) until the numerical rating pain scale score or VAS is 3/10 at most; (7) antibiotics- prophylactic antibiotics should be given to adult patients with isolated mandibular body fractures with concomitant mucosal or skin opening with or without direct visualization of bone fragments; penicillin is the drug of choice while clindamycin may be used as an alternative; and (14) prevention- clinicians should advocate for compliance with road traffic safety laws (speed limit, anti-drunk driving, seatbelt and helmet use) for the prevention of motor vehicle, cycling and pedestrian accidents and maxillofacial injuries.The guideline development group made recommendations for the following key action statements: (1) history, clinical presentation, and diagnosis - clinicians should consider a presumptive diagnosis of mandibular fracture in adults presenting with a history of traumatic injury to the jaw plus a positive tongue blade test, and any of the following: malocclusion, trismus, tenderness on jaw closure and broken tooth; (2) panoramic x-ray - clinicians may request for panoramic x-ray as the initial imaging tool in evaluating patients with a presumptive clinical diagnosis; (3) radiographs - where panoramic radiography is not available, clinicians may recommend plain mandibular radiography; (4) computed tomography - if available, non-contrast facial CT Scan may be obtained; (5) immobilization - fractures should be temporarily immobilized/splinted with a figure-of-eight bandage until definitive surgical management can be performed or while initiating transport during emergency situations; (8) anesthesia - nasotracheal intubation is the preferred route of anesthesia; in the presence of contraindications, submental intubation or tracheostomy may be performed; (9) observation - with a soft diet may serve as management for favorable isolated nondisplaced and nonmobile mandibular body fractures with unchanged pre - traumatic occlusion; (10) closed reduction - with immobilization by maxillomandibular fixation for 4-6 weeks may be considered for minimally displaced favorable isolated mandibular body fractures with stable dentition, good nutrition and willingness to comply with post-procedure care that may affect oral hygiene, diet modifications, appearance, oral health and functional concerns (eating, swallowing and speech); (11) open reduction with transosseous wiring - with MMF is an option for isolated displaced unfavorable and unstable mandibular body fracture patients who cannot afford or avail of titanium plates; (12) open reduction with titanium plates - ORIF using titanium plates and screws should be performed in isolated displaced unfavorable and unstable mandibular body fracture; (13) maxillomandibular fixation - intraoperative MMF may not be routinely needed prior to reduction and internal fixation; and (15) promotion - clinicians should play a positive role in the prevention of interpersonal and collective violence as well as the settings in which violence occurs in order to avoid injuries in general and mandibular fractures in particular.
