RESUMEN

OBJECTIVE: To describe the methodology used by the Reassessment Campaign on Veterinary Resuscitation (RECOVER) to re-evaluate the scientific evidence relevant to CPR in small and large animals, to newborn resuscitation, and to first aid and to formulate the respective consensus-based clinical guidelines. DESIGN: This report describes the evidence-to-guidelines process employed by RECOVER that is based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach and includes Information Specialist-driven systematic literature search, evidence evaluation conducted by more than 200 veterinary professionals, and provision of clinical guidelines in the domains of Preparedness and Prevention, Basic Life Support, Advanced Life Support, Post-cardiac Arrest Care, Newborn Resuscitation, First Aid, and Large Animal CPR. SETTING: Transdisciplinary, international collaboration in academia, referral practice, and general practice. RESULTS: For this update to the RECOVER 2012 CPR guidelines, we answered 135 Population, Intervention, Comparator, and Outcome (PICO) questions with the help of a team of Domain Chairs, Information Specialists, and more than 200 Evidence Evaluators. Most primary contributors were veterinary specialists or veterinary technician specialists. The RECOVER 2024 Guidelines represent the first veterinary application of the GRADE approach to clinical guideline development. We employed an iterative process that follows a predefined sequence of steps designed to reduce bias of Evidence Evaluators and to increase the repeatability of the quality of evidence assessments and ultimately the treatment recommendations. The process also allowed numerous important knowledge gaps to emerge that form the foundation for prioritizing research efforts in veterinary resuscitation science. CONCLUSIONS: Large collaborative, volunteer-based development of evidence- and consensus-based clinical guidelines is challenging and complex but feasible. The experience gained will help refine the process for future veterinary guidelines initiatives.

RESUMEN

OBJECTIVE: This study aimed to evaluate the methodological quality of existing meta-analyses (MA) and the quality of evidence for outcome indicators to provide an updated overview of the evidence concerning the therapeutic efficacy of the Mediterranean diet (MD) for various types of CVD. DESIGN: We conducted comprehensive searches of PubMed, Cochrane Library, and Embase databases. The quality of the MA was assessed using the A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) checklist, while the Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence evaluation system was employed to evaluate the quality of evidence for significant outcomes. SETTING: The CVD remains a significant contributor to global mortality. Multiple MA have consistently demonstrated the efficacy of medical interventions in managing CVD. However, due to variations in the scope, quality and outcomes of these reviews, definitive conclusions are yet to be established. PARTICIPANTS: This study included five randomized trials and twelve non-randomized studies, with a combined participant population of 716 318. RESULTS: The AMSTAR 2 checklist revealed that 54·55 % of the studies demonstrated high quality, while 9·09 % exhibited low quality, and 36·36 % were deemed critically low quality. Additionally, there was moderate evidence supporting a positive correlation between MD and CHD/acute myocardial infarction, stroke, heart failure, cardiovascular events, coronary events and major adverse cardiovascular events. CONCLUSIONS: This study indicates that although recognizing the potential efficacy of MD in managing CVD, the quality of the methodology and the evidence for the outcome indicators remain unsatisfactory.

RESUMEN

OBJECTIVE: To revise the 2017 clinical practice guidelines (CPG) for the management of microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) to reflect advancements in the field. METHODS: Similar to the 2017 CPG, the Grading of Recommendations, Assessment, Development, and Evaluation system was adopted for this revision. The intended users of this CPG include patients diagnosed with MPA or GPA in Japan and their families and healthcare professionals, including specialists and non-specialists. Based on a scoping review, four clinical questions (CQs) of the 2017 guidelines were modified, and six new CQs were added. RESULTS: We suggest a combination of glucocorticoid and cyclophosphamide or rituximab for remission induction therapy. In cases where cyclophosphamide or rituximab is used, we suggest the use of avacopan over high-dose glucocorticoid. Furthermore, we suggest against the use of plasma exchange in addition to the standard treatment in severe cases of MPA/GPA. Finally, we suggest the use of glucocorticoid and rituximab over glucocorticoid and azathioprine for remission maintenance therapy. CONCLUSIONS: The recommendations have been updated based on patient preference, certainty of evidence, benefit and risk balance, and cost.

RESUMEN

BACKGROUND: Breastfeeding self-efficacy has been proven to play a predictive role in enhancing breastfeeding initiation and continuation. Breastfeeding self-efficacy measurement tools have facilitated healthcare professionals' early identification and support of women at higher risk of early discontinuation of breastfeeding. RESEARCH AIM: The aim of this study was to assess the psychometric properties of breastfeeding self-efficacy measurement tools. METHOD: A systematic review was carried out in three phases. Phase One comprised a systematic literature review performed in PubMed, SCOPUS, Web of Science, and Cochrane Database of Systematic Reviews from February 2021 to January 2023, including 36 studies for final analysis. Phase Two provided a quality appraisal of the psychometric properties of each of the seven breastfeeding self-efficacy measurement tools, according to COnsensus-based Standards for the selection of health Measurement Instrument checklist (COSMIN) guidelines. Phase Three summarized and graded the overall quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) modified approach. RESULT: The included articles comprised 9,225 participants and seven breastfeeding self-efficacy measurement tools. The Breastfeeding Self-Efficacy Scale, Breastfeeding Self-Efficacy Scale - Short Form (BSES-SF), and Prenatal Breastfeeding Self-Efficacy Scale were supported by Grade A evidence sustaining their validity and reliability to assess breastfeeding self-efficacy in the continuum of maternity care. The BSES-SF is the most feasible tool in clinical practice and the most utilized internationally, available in 15 languages. CONCLUSION: This systematic review provided a Grade A recommendation on breastfeeding measurement tools that will be helpful both for clinical and research purposes.Registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42021238450).

RESUMEN

BACKGROUND: The GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach is a system for transparent evaluation of the certainty of evidence used in clinical practice guidelines and systematic reviews. GRADE is a key part of evidence-based medicine (EBM) training of health care professionals. OBJECTIVE: This study aimed to compare web-based and face-to-face methods of teaching the GRADE approach for evidence assessment. METHODS: A randomized controlled trial was conducted on 2 delivery modes of GRADE education integrated into a course on research methodology and EBM with third-year medical students. Education was based on the Cochrane Interactive Learning "Interpreting the findings" module, which had a duration of 90 minutes. The web-based group received the web-based asynchronous training, whereas the face-to-face group had an in-person seminar with a lecturer. The main outcome measure was the score on a 5-question test that assessed confidence interval interpretation and overall certainty of evidence, among others. Secondary outcomes included writing a recommendation for practice and course satisfaction. RESULTS: In all, 50 participants received the web-based intervention, and 47 participants received the face-to-face intervention. The groups did not differ in the overall scores for the Cochrane Interactive Learning test, with a median of 2 (95% CI 1.0-2.0) correct answers for the web-based group and 2 (95% CI 1.3-3.0) correct answers for the face-to-face group. Both groups gave the most correct answers to the question about rating a body of evidence (35/50, 70% and 24/47, 51% for the web-based and face-to-face group, respectively). The face-to-face group better answered the question about the overall certainty of evidence question. The understanding of the Summary of Findings table did not differ significantly between the groups, with a median of 3 correct answers to 4 questions for both groups (P=.352). The writing style for the recommendations for practice also did not differ between the 2 groups. Students' recommendations mostly reflected the strengths of the recommendations and focused on the target population, but they used passive words and rarely mentioned the setting for the recommendation. The language of the recommendations was mostly patient centered. Course satisfaction was high in both groups. CONCLUSIONS: Training in the GRADE approach could be equally effective when delivered asynchronously on the web or face-to-face.

RESUMEN

Background: Systematic comparisons of the doses of the Food and Drug Administration (FDA)-approved dual orexin receptor antagonists (DORAs) for people with insomnia are limited. Methods: PubMed, Embase, Cochrane Library, and Clinicaltrials. gov were systematically searched to identify relevant studies published before 31 October 2022. We assessed the certainty of evidence using the confidence in network meta-analysis (CINeMA) framework. Results: We pooled 7257 participants from 9 randomized controlled trials (RCTs). Moderate to high certainty evidence demonstrated suvorexant (20 and 40 mg) and daridorexant (10 and 50 mg) as the most effective in latency to persistent sleep (LPS) reduction. Lemborexant at 5 and 10 mg was the most effective in subjective sleep onset time (sTSO) reduction. For wake time after sleep onset (WASO), all drugs except daridorexant 5 mg were more effective than placebo. Lemborexant 5 mg was among the best in subjective WASO (sWASO) (moderate to high certainty) and had the highest surface under the curve ranking area (SUCRA) values for sWASO (100%). For total sleep time (TST), suvorexant and daridorexant, except the respective minimum doses, were more effective than placebo, while suvorexant 40 mg and lemborexant 10 mg may have been the most effective for subjective TST (sTST) (low to very low certainty). Suvorexant 40 mg (RR 1.09), suvorexant 80 mg (RR 1.65), and daridorexant 25 mg (RR 1.16) showed a higher safety risk than placebo. Conclusion: Suvorexant 20 mg, lemborexant 5 mg, lemborexant 10 mg, and daridorexant 50 mg represent suitable approaches for insomnia.

RESUMEN

To develop evidence-based recommendations for clinicians caring for adults with acute liver failure (ALF) or acute on chronic liver failure (ACLF) in the ICU. The guideline panel comprised 27 members with expertise in aspects of care of the critically ill patient with liver failure or methodology. We adhered to the Society of Critical Care Medicine standard operating procedures manual and conflict-of-interest policy. Teleconferences and electronic-based discussion among the panel, as well as within subgroups, served as an integral part of the guideline development. In part 2 of this guideline, the panel was divided into four subgroups: neurology, peri-transplant, infectious diseases, and gastrointestinal groups. We developed and selected Population, Intervention, Comparison, and Outcomes (PICO) questions according to importance to patients and practicing clinicians. For each PICO question, we conducted a systematic review and meta-analysis where applicable. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence to decision framework to facilitate recommendations formulation as strong or conditional. We followed strict criteria to formulate best practice statements. We report 28 recommendations (from 31 PICO questions) on the management ALF and ACLF in the ICU. Overall, five were strong recommendations, 21 were conditional recommendations, two were best-practice statements, and we were unable to issue a recommendation for five questions due to insufficient evidence. Multidisciplinary, international experts formulated evidence-based recommendations for the management ALF and ACLF patients in the ICU, acknowledging that most recommendations were based on low quality and indirect evidence.

RESUMEN

OBJECTIVE: To re-evaluate the systematic review/Meta-analysis of acupuncture and moxibustion for childhood autism (CA), aiming to provide decision-making basis for clinical diagnosis and treatment. METHODS: The systematic review and/or Meta-analysis of acupuncture and moxibustion for CA were searched in PubMed, EMbase, Cochrane Library, SinoMed, CNKI and Wanfang databases. The retrieval time was from the database establishment to May 5th, 2022. PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and AMSTAR 2 (a measurement tool to assess systematic reviews 2) was used to evaluate the methodological quality, bubble map was used to construct the evidence map and GRADE was used to evaluate the quality of evidence. RESULTS: A total of 9 systematic reviews were included. The PRISMA scores ranged from 13 to 26. The report quality was low, and there was a serious lack in the aspects of program and registration, search, other analysis and funding. The main problems in methodology included not making prespecified protocol, incomplete retrieval strategy, not providing a list of excluded literatures, and incomplete explanation on heterogeneity analysis and bias risk. The evidence map showed that 6 conclusions were valid, 2 conclusions were possible valid and 1 conclusion was uncertain valid. The overall quality of evidence was low, and the main factors leading to the downgrade were limitations, followed by inconsistency, imprecision and publication bias. CONCLUSION: Acupuncture and moxibustion has a certain effect for CA, but the quality of reporting, methodology and evidence in included literature need to be improved. It is suggested to perform high-quality and standardized research in the future to provide evidence-based basis.

RESUMEN

Aim: Positive pressure ventilation via a facemask is critical in neonatal resuscitation, but frequently results in mask leak, obstruction, and inadequate respiratory support. This systematic review aimed to determine whether the display of respiratory function monitoring improved resuscitation or clinical outcomes. Methods: Randomized controlled trials comparing outcomes when respiratory function monitoring was displayed versus not displayed for newborns requiring positive pressure ventilation at birth were selected and from databases (last search August 2022), and assessed for risk of bias using Cochrane Risk of Bias Tools for randomized control trials. The study was registered in the Prospective Register of Systematic Reviews. Grading of Recommendations, Assessment, Development and Evaluations was used to assess the certainty of evidence. Treatment recommendations were approved by the Neonatal Life Support Task Force of the International Liaison Committee on Resuscitation. Results reported primary and secondary outcomes and included resuscitation and clinical outcomes. Results: Of 2294 unique articles assessed for eligibility, three randomized controlled trials were included (observational studies excluded) (n = 443 patients). For predefined resuscitation and clinical outcomes, these studies either did not report the primary outcome (time to heart rate ≥ 100 bpm from birth), had differing reporting methods (achieving desired tidal volumes, significant mask leak) or did not find significant differences (intubation rate, air leaks, death before hospital discharge, severe intraventricular hemorrhage, chronic lung disease). Limitations included limited sample size for critical outcomes, inconsistent definitions amongst studies and unreported long-term outcomes. Conclusion: Although respiratory function monitoring has been utilized in clinical care, there is currently insufficient evidence to suggest its benefit for newborn infants receiving respiratory support for resuscitation at birth. Registration: PROSPERO CRD42021278169 (registered November 27, 2021). Funding: The International Liaison Committee on Resuscitation provided support that included access to software platforms and teleconferencing.

RESUMEN

Background: Respiratory distress is common during transition after birth, but the effect of continuous positive airway pressure applied in the delivery room has not been systematically evaluated in spontaneously breathing term and ≥34+0 weeks' gestation infants.We aimed to compare delivery room continuous positive airway pressure with no delivery room continuous positive airway pressure for term and ≥34+0 weeks' gestation newborn infants at birth. Methods: Information sources: Medline, Embase, Cochrane Databases, Database of Abstracts of Reviews of Effects, and Cumulative Index to Nursing and Allied Health Literature. The Databases were last searched in October 2021.Eligibility criteria: Randomized, quasi-randomized, interrupted time series, controlled before-after, and cohort studies with English abstracts.Synthesis of results: Two authors independently extracted data, assessed risk of bias, and certainty of evidence. The main outcome was admission to the neonatal intensive care unit (NICU) or higher level of care receiving any positive pressure support. Data were pooled using fixed effects models.Risk of bias: Was assessed using the Cochrane Risk of Bias Tool for randomized trials and the Non-Randomized Studies of Interventions Tool (ROBINS-I) for observational studies. Results: In this meta-analysis, two randomized control trials (323 newborns delivered by cesarean section) showed that delivery room continuous positive airway pressure decreased the likelihood of NICU admission (risk ratio (RR) 95% confidence interval (CI) 0.27 (0.11-0.66), p < 0.005) and NICU respiratory support (RR (95% CI) 0.18 (0.05-0.60), p = 0.005) when compared with no delivery room continuous positive airway pressure. However, in two before-after studies (8,476 newborns), delivery room continuous positive airway pressure use was associated with an increased risk of air leak syndrome when compared with no delivery room continuous positive airway pressure. Discussion: Certainty of evidence was very low for all outcomes. Among term and ≥34+0 weeks' gestation infants having or at risk of having respiratory distress, there is insufficient evidence to suggest for or against routine use of continuous positive airway pressure in the delivery room.Funding: No Funding has been received to conduct this study.Clinical Trial Registration: This systematic review has been registered with the International Prospective Register of Systematic Reviews (http://www.crd.york.ac.uk/prospero/) [identifier: CRD42021225812].

RESUMEN

Background: A standardized discharge plan is important to continuous medical care and discharge management of stroke patients. Currently, there is a lack of high-quality, evidence-based discharge planning guidelines for stroke patients. Most existing discharge planning guidelines have been developed for other diseases and stroke-related guidelines focus more on prevention, treatment, and rehabilitation and less on discharge planning. Therefore, they do not provide a systematic and comprehensive answer to the key issues of discharge planning for stroke patients. To improve the level of recovery and quality of life of stroke patients, to better guide clinical caregivers in developing and implementing discharge plans, the Evidence-based Nursing Center of West China Hospital, Sichuan University and the World Health Organization (WHO) Collaborating Centre for Guideline Implementation and Knowledge Translation have jointly initiated the development of the clinical practice guideline for discharge planning of patients with stroke. Methods: The guideline development process is designed to follow the WHO handbook for guideline development and Guidelines 2.0. Evidence grading and guideline recommendations are based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The key steps in developing the guideline include: (I) establishing the guideline working groups; (II) selecting the priority clinical questions; (III) evidence retrieval and evaluation; (IV) grading the quality of evidence; (V) forming recommendations; and (VI) external review. Discussion: This guideline will follow the clinical characteristics and management priorities of stroke and will be developed by a multidisciplinary guideline development team, in strict accordance with the core principles and methods of guideline development. This guideline will provide an evidence-based reference for standardized discharge screening, assessment, discharge procedures, and outpatient follow up, so as to improve the quality of discharge services and standardize the discharge management of stroke patients, and ultimately improve their post-discharge rehabilitation and quality of life. Trial Registration: The guideline was registered at the Practice guidelines REgistration for transPAREncy. The registration No. is IPGRP-2022CN331.

RESUMEN

Aim: Identify the existing evidence base with regards to interventions that address high levels of dental caries. A discussion of the applicability of the evidence to possible replication in Saudi Arabia is presented, alongside recommendations to help reduce dental caries rates in children in Saudi Arabia. Methods: A comprehensive systematic review following PRISMA methods was conducted using three databases: MEDLINE via OVID; EMBASE via OVID and Cochrane Library. Studies were included according to inclusion criteria. AMSTAR2 was used to assess the quality of the included studies, while GRADE was used to assess the quality of evidence. Results: Ten studies were included in this review. The quality of these were 'high' (in two review), moderate (in two studies), low (in one study) and to 'critically low' (5 reviews). The quality of the evidence presented by the reviews ranged from 'moderate' to 'very low'. The interventions methods included MI, one-to-one nutrition advice, educational interventions and dental screening. The applicability of the findings in relation to dental care in Saudi Arabia is discussed and summarized in a narrative. Conclusion: No strong evidence that supported interventions to improve the child oral health in Saudi Arabia was found. None of the included reviews included studies conducted in Saudi Arabia or evaluated interventions among the local community. As for different culture values, norms, beliefs and attitude to those demographics explored in the reviews, it is unclear if interventions with improve oral health among Saudi children. Further research is needed to explore the efficacy of these interventions in a Saudi context.

RESUMEN

Context: Upper airway suctioning at birth was considered standard procedure and is still commonly practiced. Negative effects could exceed benefits of suction. Question: In infants born through clear amniotic fluid (P) does suctioning of the mouth and nose (I) vs no suctioning (C) improve outcomes (O). Data sources: Information specialist conducted literature search (12th September 2021, re-run 17th June 2022) using Medline, Embase, Cochrane Databases, Database of Abstracts of Reviews of Effects, and CINAHL. RCTs, non-RCTs and observational studies with a defined selection strategy were included. Unpublished studies, reviews, editorials, animal and manikin studies were excluded. Data extraction: Two authors independently extracted data, risk of bias was assessed using the Cochrane ROB2 and ROBINS-I tools. Certainty of evidence was assed using the GRADE framework. Review Manager was used to analyse data and GRADEPro to develop summary of evidence tables. Meta-analyses were performed if ≥2 RCTs were available. Outcomes: Primary: assisted ventilation. Secondary: advanced resuscitation, oxygen supplementation, adverse effects of suctioning, unanticipated NICU admission. Results: Nine RCTs (n = 1096) and 2 observational studies (n = 418) were identified. Two RCTs (n = 280) with data concerns were excluded post-hoc. Meta-analysis of 3 RCTs, (n = 702) showed no difference in primary outcome. Two RCTs (n = 200) and 2 prospective observational studies (n = 418) found lower oxygen saturations in first 10 minutes of life with suctioning. Two RCTs (n = 200) showed suctioned newborns took longer to achieve target saturations. Limitations: Certainty of evidence was low or very low for all outcomes. Most studies selected healthy newborns limiting generalisability and insufficient data was available for planned subgroup analyses. Conclusions: Despite low certainty evidence, this review suggests no clinical benefit from suctioning clear amniotic fluid from infants following birth, with some evidence suggesting a resulting desaturation. These finding support current guideline recommendations that this practice is not used as a routine step in birth. Funding: The International Liaison Committee on Resuscitation provided access to software platforms, an information specialist and teleconferencing. Clinical Trial Registration: This systematic review was registered with the Prospective Register of Systematic Reviews (https://www.crd.york.ac.uk/prospero/) (identifier: CRD42021286258).

RESUMEN

Background: Due to lack of targeted treatment options and inconsistent utilization of histologic endpoints among clinical trials, identifying efficacious pharmacotherapies for nonalcoholic steatohepatitis [NASH] has proven challenging. Methods: A thorough systematic review and frequentist random-effects network meta-analysis was performed across all randomized clinical trials reporting a pharmacotherapeutic intervention on biopsy-proven NASH. Primary outcomes were based on the most current, up-to-date recommended histologic endpoints. Results: A total of 40 RCTs were identified including 6593 total patients. The most effective and statistically significant treatment interventions for minimum two-point improvement in NAFLD Activity Score were aldafermin 1 mg [RR 7.69, 95% CI 2.00; 29.57], vitamin E 800 IU in combination with pioglitazone 45 mg [RR 3.38, 95% CI 1.88; 6.07], pioglitazone 45 mg [RR 3.29, 95% CI 1.74; 6.22], vitamin E 800 IU [RR 2.06, 95% CI 1.33; 3.18], resmetirom 80 mg [RR 1.74, 95% CI 1.03; 2.94], obeticholic acid 25 mg [RR 1.63, 95% CI 1.32; 2.01], and obeticholic acid 10 mg [RR 1.31, 95% CI 1.02; 1.67]). The most robust pharmacotherapies for NASH resolution without worsening fibrosis were found to be aldafermin 1 mg [RR 5.77, 95% CI 1.48; 22.51], pioglitazone 45 mg [RR 2.65, 95% CI 1.43; 4.91], vitamin E 800 IU in combination with pioglitazone 45 mg [RR 2.64, 95% CI 1.36; 5.12], pioglitazone 30 mg [RR 2.46, 95% CI 1.56; 3.88], vitamin E 800 IU [RR 1.90, 95% CI 1.20; 3.00], and obeticholic acid 25 mg [RR 1.52, 95% CI 1.03; 2.23]). Obeticholic acid had a significant improvement on fibrosis. Multiple interventions were found to improve individual histologic scores across secondary outcome analyses and are detailed below. Conclusion: This novel systematic review and network meta-analysis represents the most comprehensive investigation to date regarding the pharmacotherapeutic options for biopsy-proven NASH using current recommended histologic endpoints.

RESUMEN

Background: The long-term prognosis of COVID-19 survivors remains poorly understood. It is evidenced that the lung is the main damaged organ in COVID-19 survivors, most notably in impairment of pulmonary diffusion function. Hence, we conducted a meta-analysis of the potential risk factors for impaired diffusing capacity for carbon monoxide (DLCO) in convalescent COVID-19 patients. Methods: We performed a systematic search of PubMed, Web of Science, Embase, and Ovid databases for relevant studies from inception until January 7, 2022, limited to papers involving human subjects. Studies were reviewed for methodological quality. Fix-effects and random-effects models were used to pool results. Heterogeneity was assessed using I2. The publication bias was assessed using the Egger's test. PROSPERO registration: CRD42021265377. Findings: A total of eighteen qualified articles were identified and included in the systematic review, and twelve studies were included in the meta-analysis. Our results showed that female (OR: 4.011; 95% CI: 2.928-5.495), altered chest computerized tomography (CT) (OR: 3.002; 95% CI: 1.319-6.835), age (OR: 1.018; 95% CI: 1.007-1.030), higher D-dimer levels (OR: 1.012; 95% CI: 1.001-1.023) and urea nitrogen (OR: 1.004;95% CI: 1.002-1.007) were identified as risk factors for impaired DLCO. Interpretation: Pulmonary diffusion capacity was the most common impaired lung function in recovered patients with COVID-19. Several risk factors, such as female, altered chest CT, older age, higher D-dimer levels and urea nitrogen are associated with impairment of DLCO. Raising awareness and implementing interventions for possible modifiable risk factors may be valuable for pulmonary rehabilitation.

RESUMEN

This systematic review aimed to update the management of sleep bruxism (SB) in adults, as diagnosed using polysomnography (PSG) and/or electromyography (EMG). Management methods covered were oral appliance therapy (OAT) with stabilization splints, cognitive-behavioral therapy (CBT), biofeedback therapy (BFT), and pharmacological therapy. A comprehensive search was conducted on MEDLINE, Cochrane Library, and Web of Science up to October 1st, 2021. Reference list searches and hand searches were also performed by an external organization. Two reviewers for each therapy independently performed article selection, data extraction, and risk of bias assessment. The reviewers resolved any disagreements concerning the assortment of the articles by discussion. Finally, 11, 3, 14, and 22 articles were selected for each therapy. The results suggested that OAT tended to reduce the number of SB events, although there was no significant difference compared to other types of splints, that the potential benefits of CBT were not well supported, and that BFT, rabeprazole, clonazepam, clonidine, and botulinum toxin type A injection showed significant reductions in specific SB parameters, although several side effects were reported. It can be concluded that more methodologically rigorous randomized large-sample long-term follow-up clinical trials are needed to clarify the efficacy and safety of management for SB.

RESUMEN

A significant number of individuals suffer from low back pain throughout their lifetime, and the medical costs related to low back pain and disc herniation are gradually increasing in Korea. Korean medicine interventions have been used for the treatment of lumbar intervertebral disc herniation. Therefore, we aimed to update the existing Korean medicine clinical practice guidelines for lumbar intervertebral disc herniation. A review of the existing guidelines for clinical treatment and analysis of questionnaires targeting Korean medicine doctors were performed. Subsequently, key questions on the treatment method of Korean medicine used for disc herniation in actual clinical trials were derived, and drafts of recommendations were formed after literature searches using the Grading of Recommendations, Assessment, Development and Evaluation. An expert consensus was reached on the draft through the Delphi method and final recommendations were made through review by the development project team and the monitoring committee. Fifteen recommendations for seven interventions for lumbar disc herniation were derived, along with the grade of recommendation and the level of evidence. The existing Korean medicine clinical practice guidelines for lumbar intervertebral disc herniation have been updated. Continuous updates will be needed through additional research in the future.
