Objective: To describe the prevalence, onset, associated symptoms, and clinical characteristics of COVID-19 in-patients with olfactory and gustatory dysfunction at the Philippine General Hospital from March 2021 to January 2022 and determine the number of patients with olfactory dysfunction/dysgeusia who recovered or expired. : Methods Design: Prospective Cohort Study Setting: COVID-19 Referral Hospital (Tertiary National University Hospital) Participants: COVID-19 RT-PCR positive in-patients, ages 19 and older Results: A total of 207 patients were included. Sixty-four (64) patients reported olfactory dysfunction and 79 reported dysgeusia. Olfactory and gustatory dysfunction were observed early in the course of infection, before day 6 of illness. The average length of hospital stay was 20.36 days; those with olfactory dysfunction stayed for 17.53 days, dysgeusia for 19.92 days, and 21.09 days for those who noted neither. For those subsequently intubated, 0 had olfactory dysfunction, three reported dysgeusia, three had both and six had neither. Thirteen (13) patients in the study expired. Among them, none reported olfactory dysfunction and two had dysgeusia. Conclusions Our results corroborate existing literature that olfactory and gustatory dysfunction as key indicators of COVID-19 with 42.5% of participants reporting these symptoms early, often before day 6 of illness. Ninety-two percent (92%) of those affected recovered and had shorter hospital stays, emphasizing the importance of recognizing these dysfunctions for improved disease detection and outcomes.

Purpose: Postoperative pancreatic fistula (POPF) remains a devastating complication of pancreatoduodenectomy (PD). Minimally invasive PD (MIPD), including laparoscopic (LPD) and robotic (RPD) approaches, have comparable POPF rates to open PD (OPD). However, we hypothesize that the likelihood of having a more severe POPF, as defined as clinically relevant POPF (CR-POPF), would be higher in an MIPD relative to OPD. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) targeted pancreatectomy dataset (2014–2020) was reviewed for any POPF after OPD. Propensity score matching (PSM) compared MIPD to OPD, and then RPD to LPD. Results: Among 3,083 patients who developed a POPF, 2,843 (92.2%) underwent OPD and 240 (7.8%) MIPD; of these, 25.0% were LPD (n = 60) and 75.0% RPD (n = 180). Grade B POPF was observed in 45.4% (n = 1,400), and grade C in 6.0% (n = 185). After PSM, MIPD patients had higher rates of CR-POPF (47.3% OPD vs. 54.4% MIPD, p = 0.037), as well as higher reoperation (9.1% vs. 15.3%, p = 0.006), delayed gastric emptying (29.2% vs. 35.8%, p = 0.041), and readmission rates (28.2% vs. 35.1%, p = 0.032). However, CR-POPF rates were comparable between LPD and RPD (56.8% vs. 49.3%, p = 0.408). Conclusion The impact of POPF is more clinically pronounced after MIPD than OPD with a more complex postoperative course. The difference appears to be attributed to the minimally invasive environment itself as no difference was noted between LPD and RPD. A clear biological explanation of this clinical observation remains missing. Further studies are warranted.

Objective: This pilot human trial demonstrates the ability of the investigational newborn hearing screening device to provide acoustic stimulation to produce evoked potentials, as well as its ability to capture and acquire auditory evoked potentials, especially the auditory brainstem response (ABR) wave V. This pilot study also demonstrates the ease of recognizing and identifying ABR waves in the graphical presentation of the evoked potentials over time. Methods: Fourteen normal-hearing adults or a total of twenty-eight (28) normal-hearing adult ears underwent auditory brainstem response testing using the investigational hearing screening device. A commercially available auditory brainstem response detection device was used to confirm that the acquired ABR waves of the investigational device are normal. The ABR waves displayed by the investigation device were also reviewed by the clinical audiologists to determine their recognizability and identifiability. Results: The pilot trial demonstrates the ability of the investigational newborn hearing screening device in providing acoustic stimulation to produce evoked potentials, and in acquiring and capturing ABR waves, specifically the wave V, among normal-hearing adult ears. The clinical audiologists recognized and identified the ABR wave V among the evoked potentials at 40dB, 60dB, and 80dB acoustic stimulation. About eighty-nine percent (89.2%) of all ears tested had identifiable and recognizable wave V upon acoustic stimulation at 40dB. Conclusion The investigational hearing screening device: (1) can provide acoustic stimulation to produce evoked potentials, (2) can accurately capture and acquire these evoked potentials, (3) can present these evoked potentials in a voltage per time graphical display which an audiologist and trained HCP can easily read and interpret (diagnostic ABR), and (4) can present wave V auditory brainstem potentials that can be easily identified by an audiologist and trained HCP (screening ABR).

Objectives: We present in this article the design and evaluation of a blended learning approach for training community healthcare providers in performing newborn hearing screening (NHS). Methods: We developed a blended learning course for training community healthcare providers on eHealth-enabled NHS, following Bloom’s revised taxonomy of educational objectives. The training involved three components: computer-based training (CBT), face-to-face (FTF) training, and on-site coaching. We used surveys and post-training interviews following Level 1 Kirkpatrick’s training evaluation model to get initial feedback on the training program. Results: Thirty-one community healthcare providers from five rural health units and a private hearing screening center, with a mean age of 42.2 ± 12.0 years, participated in the pilot. 93.5% of the participants agreed that the program content met stated objectives and was relevant to their practice. The length of the course was perceived to be adequate. Overall satisfaction with the program was rated at 8.5 ± 0.9 (with ten as the highest). The majority expressed that the CBT and FTF course were satisfactory at 93.5% and 100%, respectively. All participants agreed that the course enhanced their knowledge of newborn hearing screening and telehealth. Positive reviews were received from participants on the use of CBT to improve theoretical knowledge before FTF training. Participants declared that FTF training and on-site coaching helped improved NHS skills and implementation. Conclusion Competent community healthcare providers are critical to strengthening the performance of the health system, and advances in the education and technology sectors offer promising potential in upskilling local healthcare providers. The increasing access of Filipino healthcare providers to improved information and communications technology (ICT) is a significant catalyst for pedagogical innovation, like the use of blended learning in the continuous professional development of health practitioners. As ICTs gradually penetrate the health sector, the challenge we now face is not whether but how we can use innovations in education strategies to benefit healthcare providers.

RATIONALE: In 2008, the Philippine College of Surgeons in collaboration with the Philippine Society of General Surgeons and the Philippine Academy of Head and Neck Surgeons, Inc. had published Evidence-based Clinical Practice Guidelines (CPG) on the Diagnosis and Management of Thyroid Nodules. This was followed by an update in 2013 with a focus on important diagnostic and therapeutic management issues concerning thyroid malignancy. The objective of this study was to assess knowledge gaps and behavioral patterns among users with respect to these CPGs. METHODS: A validated 30 item survey assessing knowledge of, attitudes towards, and adherence to the recommendations of different Evidence based Clinical Practice Guidelines was administered to general surgery residents, PSGS fellows, and otorhinolaryngology residents and consultants performing thyroidectomies. RESULTS: There were 343 assessable forms. Of the respondents, 276 (80.47%) were general surgeons, 33 (9.62%) were otorhinolaryngologists. There were 66 (19.24%) consultants, and 277 (80.76%) residents. Otorhinolaryngologists were less aware of the local CPGs than their GS counterparts. GS Residents, compared to their consultants, were more aware of the American Thyroid Association guidelines than the local guidelines. Among all respondents, the local guidelines had about equal preference for usage as the American Thyroid Association guidelines. There were no statistically significant differences on the level of knowledge and attitudes among the respondents. CONCLUSION The level of awareness about the PCS Thyroid Guidelines needs to be improved. The dissemination process needs to be reviewed and ensure that all stakeholders will be reached.

INTRODUCTION: Lockdowns and quarantine measures during the pandemic have led to increased media consumption among students worldwide. This study aimed to determine the association between the status of the psychological well-being of medical students in a private tertiary institution and social media use during the pandemic. METHODS: This is cross-sectional analytical study which included medical students in a private tertiary institution. SONTUS was used to measure social media usage, while Ryff’s Scales of Psychological Well- Being was used to assess the psychological well-being. PRR and Chi-square test were used for data analysis. RESULTS: There were 317 respondents in the study. Based on the results of SONTUS, there are 114 respondents who have high usage. For the Ryff’s scale, there were 76 respondents who have low well- being scores. The computed Pearson Chi-square has an associated probability (p-value) of 0.855 which is more than the set significance level of 0.05. For the PRR, the computed value was 1.04. CONCLUSION There was no association found between the psychological well-being status of medical students in a private tertiary institution and social media use during the pandemic.

As authorities braced for the arrival of the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infrastructure investments and government directives prompted action in central Viet Nam to establish capacity for genomic surveillance sequencing. From 17 November 2021 to 7 January 2022, the Pasteur Institute in Nha Trang sequenced 162 specimens from 98 150 confirmed SARS-CoV-2 cases in the region collected from 8 November to 31 December 2021. Of these, all 127 domestic cases were identified as the B.1.617.2 (Delta) variant, whereas 92% (32/35) of imported cases were identified as the B.1.1.529 (Omicron) variant, all among international flight passengers. Patients were successfully isolated, enabling health-care workers to prepare for additional cases. Most (78%) of the 32 Omicron cases were fully vaccinated, suggesting continued importance of public health and social measures to control the spread of new variants.

Of all known small molecules targeting human immunodeficiency virus (HIV) capsid protein (CA), PF74 represents by far the best characterized chemotype, due to its ability to confer antiviral phenotypes in both early and late phases of viral replication. However, the prohibitively low metabolic stability renders PF74 a poor antiviral lead. We report herein our medicinal chemistry efforts toward identifying novel and metabolically stable small molecules targeting the PF74 binding site. Specifically, we replaced the inter-domain-interacting, electron-rich indole ring of PF74 with less electron-rich isosteres, including imidazolidine-2,4-dione, pyrimidine-2,4-dione, and benzamide, and identified four potent antiviral compounds (

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.

Background: Pruritus can impair quality of life in patients with atopic dermatitis. There is evidence that acupuncture reduces pruritus and disease severity, and improves quality of life. Objectives: This study aimed to determine the efficacy of acupuncture in reducing pruritus intensity, disease severity, and medication use, and improving quality of life. Methods: This was a patient- and assessor-blinded, randomized, placebo-controlled trial. Patients diagnosed with atopic dermatitis underwent twice-weekly acupuncture for 12 weeks, with an 8-week follow-up period. Baseline and weekly assessment were done using standard data collection forms and validated assessment tools. Results: Thirty patients were randomized and 28 patients were eligible for the efficacy analysis. There were no significant differences in the baseline demographic and clinical characteristics between the True Acupuncture group (TA) (n=16) and Sham Acupuncture group (SA) (n=12). Both groups showed reduction in mean itch intensity (visual analogue scale, VAS) (p=0.024) but TA showed greater reduction (p=0.009) that was sustained after end of treatment. There was also a reduction in medication use in both groups. The comparable efficacy of SA to TA is attributed to similar peripheral receptive fields and stimulation of cutaneous C-fibers which depletes the neurotransmitters mediating pruritus and results in tachyphylaxis. Mild adverse events, such as petechiae and erythema, were noted in both groups and resolved spontaneously. Conclusion: Acupuncture is a promising adjunct treatment in atopic dermatitis with significant reduction in pruritus, disease severity and medication use and a trend towards improved quality of life. Studies with larger sample size and comparison to acupuncture points farther from the true acupuncture points are recommended.
