Objectives: To discuss the evidence and caveats associated with estimated and measured creatinine clearance (eClCr and mClCr) and glomerular filtration rate (eGFR and mGFR) assessments of kidney function in patients with more extreme forms of obesity. Data Sources: PubMed (1976 to mid-May 2020) was used, with bibliographies of retrieved articles searched for additional articles. Study Selection and Data Extraction: Articles using gold standard mGFR to evaluate eClCr, mClCr, and eGFR assessments of kidney function in patients with more extreme forms of obesity were included. Data Synthesis: The overestimation of GFR by mClCr is well established, but mClCr is an alternative to mGFR assessments for determining medication dosing in patients with extremes of body size or muscle mass, or in patients receiving narrow therapeutic index medications when eGFR is likely to be inaccurate. The vast majority of studies comparing eGFR assessments with gold standard indicators of kidney function were attempts to validate eGFR equations for diagnosing and staging chronic kidney disease (CKD). Relevance to Patient Care and Clinical Practice: For dosing medications in patients with stable kidney function and extreme obesity, a deindexed 4-variable Modification of Diet in Renal Disease or CKD Epidemiology Collaboration equation is an alternative to Cockcroft-Gault. Consistent use of the same equation by provider and between providers within any given setting is of paramount importance. Conclusions: In patients with extreme obesity and stable kidney function, eClCr or eGFR using deindexed values provides estimates of function for dosing adjustments of medications with elimination by the kidneys, but more research is needed with respect to the best size descriptor to use with estimating equations.

PurposeThe purpose of this systematic review was to identify an appropriate method—a user-friendly and validated method—that prioritises recommendations following analyses of adverse events (AEs) based on objective features.Data sourcesThe electronic databases PubMed/MEDLINE, Embase (Ovid), Cochrane Library, PsycINFO (Ovid) and ERIC (Ovid) were searched.Study selectionStudies were considered eligible when reporting on methods to prioritise recommendations.Data extractionTwo teams of reviewers performed the data extraction which was defined prior to this phase.Results of data synthesisEleven methods were identified that are designed to prioritise recommendations. After completing the data extraction, none of the methods met all the predefined criteria. Nine methods were considered user-friendly. One study validated the developed method. Five methods prioritised recommendations based on objective features, not affected by personal opinion or knowledge and expected to be reproducible by different users.ConclusionThere are several methods available to prioritise recommendations following analyses of AEs. All these methods can be used to discuss and select recommendations for implementation. None of the methods is a user-friendly and validated method that prioritises recommendations based on objective features. Although there are possibilities to further improve their features, the ‘Typology of safety functions’ by de Dianous and Fiévez, and the ‘Hierarchy of hazard controls’ by McCaughan have the most potential to select high-quality recommendations as they have only a few clearly defined categories in a well-arranged ordinal sequence.

Incidence Risk

Objective: To review the incidence, risk factors, and management of pegfilgrastim-induced bone pain (PIBP). Data Sources: PubMed was searched from 1980 to March 31, 2017, using the terms pegfilgrastim and bone pain. Study Selection and Data Extraction: English-language, human studies and reviews assessing the incidence, risk factors, and management of PIBP were incorporated. Data Synthesis: A total of 3 randomized, prospective studies and 2 retrospective studies evaluated pharmacological management of PIBP. Naproxen compared with placebo demonstrated a reduction in the degree, incidence, and duration of bone pain secondary to pegfilgrastim. Loratadine was not effective in reducing the incidence of bone pain prophylactically, but a retrospective study evaluating dual antihistamine blockade with loratadine and famotidine demonstrated a decreased incidence in bone pain when administered before pegfilgrastim. Conclusion: Naproxen is effective at managing PIBP. Although commonly used, antihistamines have a paucity of data supporting their use. Dose reductions of pegfilgrastim and opioids may also be potential management options; however, data supporting these treatment modalities are scarce.

OBJECTIVE: To review the current published clinical studies evaluating the clinical efficacy and safety of lactulose compared with other laxatives or placebo. Adverse effects associated with lactulose are also reported. DATA SOURCES: Information was retrieved by searching the MEDLINE and EMBASE databases for clinical trials, abstracts, conference proceedings, and review articles dealing with lactulose. STUDY SELECTION: Emphasis was placed on clinical trials where lactulose was compared with other laxatives or placebo in patient populations where the diagnosis of constipation was reasonably established. DATA EXTRACTION: The methodology and results from clinical studies were evaluated. Assessment of the studies was made based on diagnosis of constipation, prior management of patients, follow-up of patients, dosage, and adverse effects. DATA SYNTHESIS: Clinical trials in geriatric patients, terminally ill patients, children, and normal and constipated subjects were reviewed. In most instances, lactulose was compared with a placebo, without incorporating the current education on dietary techniques for improving defecation. CONCLUSIONS: Generally, clinical trials have demonstrated a beneficial response compared with placebo, although sometimes that response has been only marginally better, from a clinical point of view.

Abstract Objective.—To describe the results of the College of American Pathologists survey questions assessing the current practice of sweat testing in North America and to identify areas in which improvement is needed. Data Source.—Results of the supplemental questions to the SW-B 2000 survey. Study Selection.—Supplemental questions were designed to assess variation in sweat collection, analysis, and interpretation. Data Extraction.—Extractions of the data were made based on the relevance of the data to the objectives of the review. Data Synthesis.—The majority of laboratories surveyed performed sweat testing according to the procedures described in the National Committee for Clinical Laboratory Standards' document. The study revealed that a number of laboratories have adopted poor practice standards and are potentially compromising patient care. Areas of concern include the number of laboratories performing few sweat tests per year, the persistence of unreliable methodology, misunderstanding of collection parameters, lack of patient education, and erroneous result reporting. Conclusions.—The study identified areas of concern toward which educational efforts can be directed. Such efforts include the development of a College of American Pathologists accreditation checklist for sweat testing and targeted responses in the sweat analysis participant summary report.

Objective: This study aimed to comprehensively evaluate the risk of gastrointestinal bleeding (GIB) with statin monotherapy or with concomitant warfarin use. Data Sources: PubMed, Web of Science, and EMBASE (via Scopus) were searched for observational studies that reported the risk of GIB in adults on statin therapy or with concomitant warfarin use until August 28, 2021. Study Selection and Data Extraction: Observational studies evaluating the risk of GIB in adults (age >18 years) on statin medication or concomitant use with warfarin were included. Data Synthesis: In all, 14 studies with a total of 5 235 123 participants, reporting 48 677 GIB events (43 734 from statin users and 4943 from users of statin combined with warfarin), were included in the analyses. The pooled analysis revealed no difference in the risk of GIB with statin monotherapy (relative risk [RR]: 0.65; 95% CI: 0.42-1.02) or concomitant statin + warfarin use (RR: 0.97; 95% CI: 0.91-1.02). Prior use of statin was not associated with GIB risk (RR: 0.88; 95% CI: 0.63-1.22), whereas a shorter duration of statin use (<5 years) was associated with a lower risk of GIB (RR: 0.42; 95% CI: 0.18-0.97). Relevance to Patient Care and Clinical Practice: This analysis provides strong evidence on the association between statin use (with/without warfarin) and risk of GIB. Conclusion: Statin alone or combined with warfarin was not significantly associated with either an increased or decreased risk of GIB. The GIB risk was significantly lower when statins were used for a short duration (<5 years). The putative relationship between statins and GIB in warfarin users warrant further investigation.

BACKGROUND Multiple Sclerosis (MS) is an autoimmune disease that results from the demyelination of the nerves in the Central Nervous System. The diagnosis depends on clinical history, neurological examination, and radiological images. Artificial Intelligence proved to be an effective tool in enhancing the diagnostic tools of MS. OBJECTIVE To explore how AI assisted in diagnosis and predicting the progression of MS. METHODS We used three bibliographic databases in our search: PubMed IEEE Xplore and Cochrane in our search. The study selection process included: removal of duplicated articles, screening titles and abstracts, and reading the full text. This process was performed by two reviewers. The data extracted from the included studies have been filled in an Excel sheet. This step had been done by each reviewer accordingly to the assigned articles. The extracted data sheet was checked by two reviewers to have accuracy ensured. The narrative approach is applied in data synthesis. RESULTS The search conducted resulted in 320 articles Removing duplicates and excluding the ineligible articles due to irrelevancy to the population, intervention, and outcomes resulted in excluding 299 articles. Thus, our review will include 21 articles for data extraction and data synthesis. CONCLUSIONS Artificial Intelligence is becoming a trend in the medical field. Its contribution in enhancing the diagnostic tools of many diseases, as in MS, is prominent and can be built on in further development plans. However, the implementation of Artificial Intelligence in Multiple Sclerosis is not widespread to confirm the benefits gained, and the datasets involved in the current practice are relatively small. It is recommended to have more studies that focus on the relationship between the employment of AI in diagnosis and monitoring progression and the accuracy gained by this employment.

Objective: To synthesize the evidence from systematic reviews of clinical trials investigating the effectiveness of pharmacological therapies approved by the Australian Therapeutic Goods Administration and the US Food and Drug Administration for the management of obesity in adults. Data Sources: A 3-step literature search of the MEDLINE, EMBASE, CINAHL, and PubMed databases was conducted between March and May 2019. The key terms used were obesity, pharmacological therapy, antiobesity agent, antiobesity medication, weight loss, and systematic review. Study Selection and Data Extraction: Systematic reviews that evaluated the effectiveness of pharmacological therapies for the management of obesity in patients with a body mass index of or greater than 25 kg/m2. Data Synthesis: Nine systematic reviews involving three pharmacotherapies, liraglutide, orlistat, and naltrexone-bupropion were identified. The results indicate that the pharmacotherapies reduced weight when compared with placebo. Orlistat was effective in significantly reducing fasting blood glucose, HbA1c, total cholesterol, triglycerides, and systolic and diastolic blood pressure. All reviews discussed the presence or risk of gastrointestinal adverse effects including diarrhea, vomiting, and nausea related to orlistat and liraglutide. Relevance to Patient Care and Clinical Practice: This umbrella review compares the efficacy and safety of antiobesity medications for reducing weight and a discussion on their weight loss and metabolic control to guide clinicians when prescribing medications for obesity. Conclusions: All pharmacological therapies included in this review are superior to placebo in reducing weight. Clinicians should consider patient comorbidities and risk of adverse events when recommending medications for weight loss.

Objective: To review the safety, efficacy, and administration of intranasal (IN) glucagon for the management of hypoglycemia. Data Source: A literature search of PubMed/MEDLINE (1995 to November 2019) using the terms intranasal glucagon, nasal glucagon, glucagon, hypoglycemia treatment, and hypoglycemia management was completed. Study Selection and Data Extraction: English-language studies evaluating IN glucagon were evaluated. Data Synthesis: IN glucagon is a newly approved product for the treatment of hypoglycemia in patients with diabetes, 4 years and older. Administered as a 3-mg dose, it was shown to be noninferior to intramuscular (IM) glucagon. In comparison trials, more than 98% of hypoglycemic events were treated successfully with IN glucagon in both pediatric and adult patients. In simulated and real-world studies, IN glucagon was administered in less than a minute for the majority of scenarios. IM glucagon took longer to administer, ranging from 1 to 4 minutes, and often, patients did not receive the intended full dose. Nausea and vomiting, known adverse events for glucagon, as well as local adverse events were most commonly reported with IN glucagon. Relevance to Patient Care and Clinical Practice: IN glucagon is safe, effective, easy to use, and does not require reconstitution prior to use, which can lead to faster delivery in a severe hypoglycemic event. It does not require age- or weight-based dosing. This delivery method offers an option for someone who fears needles or is uncomfortable with injections. Conclusion: IN glucagon is a safe, effective, easy to use, needle-free treatment option for severe hypoglycemia.

Abstract Background Blinding of participants and therapists in trials of physical interventions is a significant and ongoing challenge. There is no widely accepted sham protocol for dry needling. Purpose The purpose of this review was to summarize the effectiveness and limitations of blinding strategies and types of shams that have been used in dry needling trials. Data Sources Twelve databases were searched from inception to February 2016. Study Selection Trials that compared active dry needling with a sham that simulated dry needling were included. Data Extraction The main domains of data extraction were participant/therapist details, intervention details, blinding strategies, blinding assessment outcomes, and key conclusions of authors. Reported blinding strategies and sham types were synthesized descriptively, with available blinding effectiveness data synthesized using a chance-corrected measurement of blinding (blinding index). Data Synthesis The search identified 4894 individual publications with 27 trials eligible for inclusion. In 22 trials, risk of methodological bias was high or unclear. Across trials, blinding strategies and sham types were heterogeneous. Notably, no trials attempted therapist blinding. Sham protocols have focused on participant blinding using strategies related to group standardization and simulation of tactile sensations. There has been little attention given to the other senses or cognitive strategies to enhance intervention credibility. Nonpenetrating sham types may provide effective participant blinding. Limitations Trials were clinically and methodologically diverse, which limited the comparability of blinding effectiveness across trials. Reported blinding evaluations had a high risk of chance findings with power clearly achieved in only 1 trial. Conclusions Evidence-based consensus on a sham protocol for dry needling is required. Recommendations provided in this review may be used to develop sham protocols so that future protocols are more consistent and potentially more effective.
