The conundrum of differentiating Cushing's syndrome from non-neoplastic hypercortisolism: a systematic review and meta-analysis.

CONTEXT: Once hypercortisolemia is confirmed, differential diagnosis between Cushing's syndrome (CS) due to neoplastic endogenous hypercortisolism and non-neoplastic hypercortisolism (NNH, pseudo-Cushing's syndrome) is crucial. Due to worldwide corticotropin-releasing hormone (CRH) unavailability, accuracy of alternative tests to dexamethasone (Dex)-CRH, is clearly needed. OBJECTIVE: Assess the diagnostic accuracy of Dex-CRH test, desmopressin stimulation test, midnight serum cortisol (MSC), and late-night salivary cortisol (LNSC) levels to distinguish CS from NNH. METHODS: Articles through March 2022 were identified from Scopus, Web of Science, MEDLINE, EMBASE, and PubMed. All steps through the systematic review were performed independently and in duplicate and strictly adhered to the updated PRISMA-DTA checklist. DATA SYNTHESIS: A total of 24 articles (1900 patients) were included. Dex-CRH had a pooled sensitivity and specificity of 91% (95%CI 87-94%; I2 0%) and 82% (73-88%; I2 50%), desmopressin test 86% (81-90%; I2 28%) and 90% (84-94%; I2 15%), MSC 91% (85-94%; I2 66%) and 81% (70-89%; I2 71%), and LNSC 80% (67-89%; I2 57%) and 90% (84-93%; I2 21%), respectively. Summary receiver operating characteristics areas under the curve were Dex-CRH 0.949, desmopressin test 0.936, MSC 0.942, and LNSC 0.950 without visual or statistical significance. The overall risk of studies bias was moderate. CONCLUSION: Dex-CRH, the desmopressin stimulation test, and MSC have similar diagnostic accuracy, with Dex-CRH and MSC having slightly higher sensitivity, and the desmopressin test being more specific. LNSC was the least accurate, probably due to high heterogeneity, intrinsic variability, different assays, and lack of consistent reported cutoffs. When facing this challenging differential diagnosis, the results presented here should increase clinicians' confidence when deciding which test to perform.

Rotator Interval vs Posterior Approach Ultrasound-guided Corticosteroid Injections in Primary Frozen Shoulder: A Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: To compare the efficacy of rotator interval (RI) vs posterior approach (PA) ultrasound (US) guided corticosteroid injections into the glenohumeral (GH) joint in primary frozen shoulder (PFS). DATA SOURCES: A systematic literature search for all relevant studies on Medline, Scopus, Embase, Web of Science, and Cochrane Central, up to January 2023 was conducted. STUDY SELECTION: Randomized controlled trials that directly compared the US-guided corticosteroid injection into the RI and GH joint using PA in patients clinically and radiographically diagnosed with PFS. DATA EXTRACTION: The primary outcome was pain, and the secondary outcomes were function, and range of motion (ROM). Two authors independently assessed the risk of bias using the Cochrane risk-of-bias tool version 2. A random-effects model and generic inverse variance method were performed. Effect sizes were estimated using mean difference (MD) and standardized mean difference (SMD). DATA SYNTHESIS: A total of 5 clinical trials involving 323 subjects were included for the meta-analysis. US-guided corticosteroid injections into the RI revealed significant pain relief (MD 1.33 [95% confidence interval (CI) 0.20 to 2.46]; P=.02) and significant functional improvement (SMD 1.31 [95% CI 0.11 to 2.51]; P=.03) compared with the PA after 12 weeks. CONCLUSION: The results suggest the injection of corticosteroid into RI space is more effective than PA after 12 weeks in improving both pain and functional scores in patients with PFS.

Anthropometric parameters to estimate body frame size in children and adolescents: A systematic review.

OBJECTIVE: To determine the most frequently body frame size (BFS) measurement and to compare the cut-off values used for classifying body size in children and adolescents. METHODS: This systematic review focused on primary studies and scientific reports published in Medline Ovid, EMBASE, Web of Science, or Scopus between January 1, 2007 and March 31, 2021. Eligible studies must have included at least one BFS parameter measured in healthy children or adolescents. A descriptive analysis and graphic comparison were performed when values of the body frame were available. RESULTS: A total of 26 studies involving 317 202 children and adolescents from all over the world were included. The report of Frame index predominated (46%). It was followed by the biacromial diameter single or combined with the bitrochanteric and biiliocristal diameter (27%), the wrist circumference (19%), and the grant index (12%). Fourteen studies reported percentile values of the BFS measurement, but only four presented cut-off values. CONCLUSIONS: There was no unified BFS measurement in children and adolescents neither reference cut-off values for categorization. The Frame index was the most frequently used. It is difficult to compare BFS statistics due to the diversity of measurements. It is necessary to standardize the use of the methods for measuring BFS.

Acanthosis nigricans in middle-age adults: A highly prevalent and specific clinical sign of insulin resistance.

BACKGROUND: Insulin resistance (IR) precedes the diagnosis of many metabolic and non-metabolic illnesses, including type 2 diabetes mellitus (T2DM). Acanthosis nigricans (AN) is a clinical sign associated with IR. However, AN prevalence and diagnostic accuracy in middle-age adults before or at the time of prediabetes/diabetes diagnosis remain uncertain. METHODS: With the aim to define AN prevalence and diagnostic accuracy, adults between 40 and 60 years of age were consecutively invited to participate in the study. Participants were categorised into one of two main groups: individuals with normoglycaemia (group 1) and hyperglycaemia (group 2 [ie, prediabetes/diabetes]). Demographic, clinical, anthropometric characteristics, homeostasis model assessment of IR, homeostatic model assessment of ß-cell function, as well as the presence of AN on the neck, axillae, elbows and knuckles were assessed. RESULTS: A total of 320 consecutive participants with a mean age of 49.3 years (59.4% women) were included. Overall, AN prevalence was 46.3%, while AN in group 1 and group 2 was 36.3% and 49.6%, respectively (P = .04). The most common affected sites in group 1 (n = 80) were the knuckles (21.2%) and the neck (17.5%), while in group 2 (n = 240), the neck (29.6%) followed by the knuckles (26.7%). The specificity and positive predictive value of AN for IR were 0.85 and 0.86 in group 1 and 0.90 and 0.96 in group 2, respectively. CONCLUSIONS: In middle-age adults, within the entire spectrum of carbohydrate tolerance, AN is highly prevalent and specific. This finding supports its assessment as a reliable and convenient clinical sign of IR. The understanding of AN behaviour through different carbohydrate tolerance strata, and its different locations, could lead to early detection of individuals at high metabolic risk or help direct a more pathophysiological treatment approach in patients with T2DM.

Does glitazone treatment have a role on the prevention of Parkinson's disease in adult diabetic population? A systematic review.

Lately, focus on the relation between Parkinson's disease (PD) and Diabetes has risen greatly, as neuroprotective properties have been attributed to insulin use. Several studies have assessed the effect of glitazones, an insulin-sensitizing agent, in diabetic population on PD future risk. However, reports on the effect of their use have been heterogeneous. We aimed to synthesize the available scientific evidence which assesses the effect of glitazone use in type 2 diabetes patients on PD incidence. A systematic review was performed on multiple electronic databases. Considered for inclusion were studies that assessed the incidence of PD in type 2 diabetes glitazone users. Two reviewers worked independently and in duplicate to assess all studies, extract information and assess the methodological quality in each included study. Four high quality retrospective cohorts fulfilled inclusion criteria. Comparison groups varied across studies. In each study, incidence of PD was lower in glitazone-exposed patients compared to their respective comparison group. Pooled analysis showed lesser risk of PD in ever versus never glitazone users (RR 0.75 [95% C.I. 0.67-0.85; p < .0001; I2 = 0]). Our pooled analysis showed lesser risk of PD in glitazone versus non glitazone users, however, we advise to take results with caution since results are non-adjusted to possible confounding variables, furthermore, different glitazone-exposure time, follow up and comparison groups are aspects that also need to be pointed out. More clinical research focused on glitazone use and its relation with PD is needed, as this could result in new potential treatment modalities.

Does axillary lymph node size predict better metastatic involvement than apparent diffusion coefficient (ADC) value in women with newly diagnosed breast cancer?

BACKGROUND: It has been demonstrated that the number of metastatic axillary lymph nodes (mALNs) influence disease-free and overall survival in patients with breast cancer. PURPOSE: To determine if the ALN size is more accurate than the ALN apparent diffusion coefficient (ADC) value to predict metastatic involvement in newly diagnosed breast cancer. MATERIAL AND METHODS: A total of 44 patients with breast cancer were included. Magnetic resonance imaging (MRI) examinations were performed on a 1.5-T system with sagittal T1-weighted fast spin-echo non-fat saturated, sagittal T2-weighted fast spin-echo non-fat saturated, axial diffusion-weighted imaging echo-planar (b values of 0 and 700 s/mm2), and non-contrast axial VIBRANT sequences. The size and the ADC value were obtained for ALN ipsilateral and contralateral to breast cancer. The reference standard was the histopathologic lymph node status. RESULTS: mALN had a greater cortical thickness compared to contralateral non-mALN (10.3 ± 5.32 mm vs. 4 ± 1.17 mm, P ≤ 0.001). The threshold of ≥6.7 mm for predicting axillary metastatic involvement had a sensitivity and a specificity of 80.0% and 97.7%, respectively. The ADC value of mALN was significantly higher than the contralateral non-mALN (0.90 ± 0.12 × 10-3mm2/s vs. 0.78 ± 0.12 × 10-3mm2/s; P = 0.001). The threshold of ≥0.86 × 10-3mm2/s had a sensitivity and a specificity of 66.7% and 76.7%, respectively. CONCLUSION: Our results indicate that the cortical thickness has a better diagnostic performance in the differentiation of metastatic and non-metastatic lymph nodes than the lymph node ADC.

Participants' awareness of ethical compliance, safety and protection during participation in pharmaceutical industry clinical trials: a controlled survey.

BACKGROUND: The rapid increase of industry-sponsored clinical research towards developing countries has led to potentially complex ethical issues to assess. There is scarce evidence about the perception of these participants about the ethical compliance, security, and protection. We sought to evaluate and contrast the awareness and perception of participants and non-participants of industry-sponsored research trials (ISRT) on ethical, safety, and protection topics. METHODS: A Cases-control survey conducted at twelve research sites in México. Previous and current participants of ISRT (cases) as well as non-participants (controls) with one of four chronic diseases, were asked to complete the survey which focused on ethical compliance and protection issues of ISRT, and the perception of participating in a trial. RESULTS: A total of 604 cases and 604 controls were surveyed. Cases significantly answered that ethics committees are aware of what is happening in studies (50.5% vs. 33.8%, P = ≤ 0.001), and that medical care of industry-sponsored research trials is better than their usual medical care (77.2% vs. 38.2%, P = < 0.001). The same proportion of cases and controls thought patients must receive economical reimbursement for participating in a research study (49.5% vs. 53.1%, P = 0.205). The informed consent of the pharmaceutical clinical trial was fully read by 90.4% of the cases. Most cases were satisfied or very satisfied with their overall study participation (35.6 and 62.3%, respectively). CONCLUSION: Previous and current participants of industry-sponsored research trials have a more positive attitude towards ethics committees, the quality of medical care of the research trials, and the main purpose of economical reimbursements, when compared to non-participants.

[Correlation between consultation time and patient´s satisfaction in primary care]. / Correlación entre tiempo consulta y satisfacción del paciente en primer nivel de atención.

Background: It is important to understand how consultation time relates to patient satisfaction, as these two variables have not been extensively studied together. Objective: To determine the correlation between consultation time and patient satisfaction in primary care settings in Mexico. Materials and methods: Cross-sectional, observational, and analytical study that included patients over 18 years old. Time was measured using a stopwatch, and satisfaction was assessed using the Patient Doctor Relationship Questionnaire (PDRQ-9). The correlation between both variables was analyzed using the Spearman test, and multiple linear regression was employed to associate satisfaction with the consultation. Results: A total of 115 participants were included. The average consultation duration was 12.1 minutes, and 74% of patients reported that the consultation time was adequate. A weak positive correlation (p < 0.001, r = 0.38) was found between actual consultation time and satisfaction. Multiple linear regression demonstrated that for every minute increase in consultation time, level of satisfaction increased in 0.04 units (p = 0.001, CI95%: 0.016-0.063). Conclusion: Most patients reported satisfaction with the duration of their medical consultation, and longer consultation times were associated with higher satisfaction levels.

Introducción: es importante conocer cómo el tiempo de la consulta se relaciona con la satisfacción del paciente, ya que son dos variables que no se han estudiado a profundidad de forma conjunta. Objetivo: determinar la correlación que existe entre el tiempo de consulta y la satisfacción del paciente en un primer nivel de atención en México. Material y métodos: estudio transversal, observacional y analítico que incluyó a pacientes mayores de 18 años. Se midió el tiempo con cronómetro, así como la satisfacción mediante el cuestionario Patient Doctor Relationship Questionnaire (PDRQ-9). Se analizó la correlación entre ambas variables con la prueba de Spearman y para asociar la satisfacción con la consulta se empleó regresión lineal múltiple. Resultados: se incluyeron 115 participantes. La duración media de la consulta fue de 12.1 minutos y el 74% de los pacientes indicó que el tiempo de consulta les pareció adecuado. Se encontró una correlación positiva leve (p < 0.001, r = 0.38) entre el tiempo real de la consulta y la satisfacción. Mediante la regresión lineal múltiple se demostró que, por cada minuto de aumento en la consulta, el índice de satisfacción aumentaba en un 0.04 (p = 0.001, IC95%: 0.016-0.063). Conclusión: la mayoría de los pacientes refieren estar satisfechos con la duración de la consulta médica; sin embargo, a mayor duración de la consulta los pacientes muestran mayor satisfacción.

Trendelenburg position for internal jugular vein catheterization: A systematic review and meta-analysis.

To determine the effect of Trendelenburg position on the diameter or cross-section area of the internal jugular vein (IJV) a systematic review and metanalysis was performed. Studies that evaluated the cross-sectional area (CSA) and anteroposterior (AP) diameter of the right internal jugular vein (RIJV) with ultrasonography in supine and any degree of head-down tilt (Trendelenburg position) were analyzed. A total of 22 articles (613 study subjects) were included. A >5° Trendelenburg position statistically increases RIJV CSA and AP diameter. Further inclination from 10° does not statistically benefit IJV size. This position should be recommended for CVC placement, when patient conditions allow it, and US-guided cannulation is not available.

Gallbladder perforation with fistulous communication.

BACKGROUND: The management of gallbladder perforation (GBP) with fistulous communication (Neimeier type I) is controversial. AIM: To recommend management options for GBP with fistulous communication. METHODS: A systematic review of studies describing the management of Neimeier type I GBP was performed according to the PRISMA guidelines. The search strategy was conducted in Scopus, Web of Science, MEDLINE, and EMBASE (May 2022). Data extraction was obtained for patient characteristics, type of intervention, days of hospitalization (DoH), complications, and site of fistulous communication. RESULTS: A total of 54 patients (61% female) from case reports, series, and cohorts were included. The most frequent fistulous communication occurred in the abdominal wall. Patients from case reports/series had a similar proportion of complications between open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) (28.6 vs 12.5; P = 0.569). Mortality was higher in OC (14.3 vs 0.0; P = 0.467) but this proportion was given by only one patient. DoH were higher in OC (mean 26.3 d vs 6.6 d). There was no clear association between higher rates of complications of a given intervention in cohorts, and no mortality was observed. CONCLUSION: Surgeons must evaluate the advantages and disadvantages of the therapeutic options. OC and LC are adequate options for the surgical management of GBP, with no significant differences.

Fetal-type posterior cerebral artery and association of rupture in posterior communicating artery aneurysms: A systematic review and meta-analysis.

BACKGROUND: The morbidity and mortality of intracranial aneurysm rupture motivate the risk evaluation of the patient´s characteristics and aneurysm's morphology. Brain vessel variants lead to hemodynamic changes that could increase risk. This study aims to evaluate the fetal posterior cerebral artery (fPCA) as a risk factor for the formation, rupture, and recurrence of the posterior communicating artery (PComA) aneurysm. METHODS: A search strategy was performed in MEDLINE, Scopus, Web of Science, and EMBASE databases for studies that evaluated the risk of appearance, rupture, and recurrence of PComA aneurysms with the presence of fPCA. Newcastle-Ottawa Scale and AXIS were used for quality assessment. The primary and secondary outcomes were evaluated and interpreted with an odds ratio (OR) and their 95% confidence intervals (CI). RESULTS: A total of 577 articles were reviewed. Thirteen studies were included for the qualitative analysis, and ten studies for the meta-analysis. All cohort studies were classified as poor quality, and all cross-sectional studies with moderate risk. The unadjusted OR resulted in 1.57 (n = 6, 95% CI 1.13-2.19, p = <0.001, I2 =0%) between the presence of fPCA and PComA aneurysm rupture. CONCLUSION: There is a significant association of aneurysm formation and rupture of PComA aneurysms in the presence of fPCA. This may be triggered by the hemodynamic alterations caused by the variation, leading to changes in the vessel wall.

[Impact of electronic devices used at an early age on language]. / Impacto del uso de dispositivos electrónicos a edad temprana en el lenguaje.

Background: The acquisition of language in infants is largely the result of the process of brain maturation, as well as environmental stimulation. Currently, society is in an era of technology and use of electronic devices from an early age. Objective: The aim of this study was to demonstrate if the amount of time of use of electronic devices in children under 5 years of age affects language development. Methods: An observational, comparative, survey-type study was carried out in 269 infants of both sexes, with an age range of 6 to <60 months. The language development section of the Child Development Scale (EDI) was used. A logistic regression was performed to determine the strength of association between the factors to be studied. Results: 269 participants were included, of which 224 (83.2%) presented their level of neurological maturation, 44 infants (16.4%) presented laged development and one (0.4%) was classified as having developmental delay. It was found that the number of daily hours that an electronic device is used behaved as a risk factor by increasing the risk of delayed language development by 1.37 times for each hour of exposure (OR: 1.37, CI95%: 1.15-1.62). Conclusions: It was shown that a greater number of hours of use of electronic devices is a risk factor for delayed language development in children under 5 years of age. Therefore, it is vital to limit its use in this population.

Introducción: la adquisición del lenguaje en los infantes es, en gran medida, resultado del proceso de maduración cerebral, así como de la estimulación ambiental. En la actualidad, la sociedad se encuentra en una era de tecnología y uso de dispositivos electrónicos desde temprana edad. Objetivo: evaluar el efecto del tiempo de uso de dispositivos electrónicos en los menores de 5 años en el área del lenguaje. Métodos: se realizó un estudio observacional, comparativo, tipo encuesta, en infantes con rango de edad de 6 a < 60 meses de ambos sexos. Se utilizó la sección para medir desarrollo del lenguaje de la Escala de Desarrollo Infantil (EDI). Adicionalmente, se llevó a cabo una regresión logística con el objetivo de determinar la fuerza de asociación entre los factores a estudiar. Resultados: se incluyeron 269 participantes, de los cuales 224 de ellos (83.2%) correspondían a su nivel de maduración neurológica, 44 infantes (16.4%) presentaron rezago en su desarrollo y uno (0.4%) se clasificó con retraso en el desarrollo. Encontramos que el número de horas diarias utilizando algún dispositivo electrónico se comportó como factor de riesgo, aumentando 1.37 veces el riesgo de retraso en el desarrollo del lenguaje por cada hora de exposición (OR: 1.37, IC95%: 1.15-1.62). Conclusiones: un mayor número de horas de uso de los dispositivos electrónicos es factor de riesgo para presentar retraso en el desarrollo del lenguaje en menores de 5 años.

Prevalence and associated factors of bullying in medical residents: A systematic review and meta-analysis.

OBJECTIVE: To assess the prevalence of bullying in medical residents and its associated factors. METHODS: In this systematic review and meta-analysis, articles from MEDLINE, EMBASE, Scopus, PsycInfo, Cochrane databases, and Web of Science were searched. Published and unpublished cross-sectional studies were included. Cochrane's Q test and I2 statistics were used to assess the existence of heterogeneity. Subgroup analysis and sensitivity analysis were performed on evidence of heterogeneity. Egger's test and funnel plots were performed to investigate publication bias. RESULTS: A total of 13 cross-sectional studies with a total of 44 566 study participants from different medical residencies were analyzed. The overall prevalence of bullying was 51% (95% CI 36-66). Furthermore, female residents and residents that belong to a minority group had higher odds of experiencing bullying compared to their peers. CONCLUSION: A high prevalence of bullying in medical residents exists around the world. There is a need for education, dissemination, and more effective interventions among the residents and authorities about bullying to build and promote adequate behaviors and diminish bullying prevalence.

The Effect of Post warming Culture Period Between Thawing and Transfer of Cryopreserved Embryos on Reproductive Outcomes After In Vitro Fertilization (IVF): A Systematic Review and Meta-analysis.

BACKGROUND: The purpose of this study was to evaluate the effect of post warming culture period between thawing and transfer of cryopreserved embryos on reproductive outcomes after in vitro fertilization (IVF). METHODS: An extensive literature search was performed using PubMed, EmBase, and the Cochrane library from January 2000 to August 2019. A systematic review and meta-analysis of clinical trials was performed in this manuscript. The trials represented patients with embryo transfers of at least one previously cryopreserved good quality embryo. Main outcome measures of the study included clinical pregnancy rate, live birth rate, miscarriage rate, and ectopic pregnancy rate. RESULTS: A total of 5338 trial/abstracts were identified through a literature search. Totally, five studies were included in the systematic review, and three in the final meta-analysis. The studies included 1717 embryo transfers, 605 after short culture, and 1112 after long culture. The clinical pregnancy rate (CPR) was the most consistent outcome reported. The CPR was slightly better after short time culture with a RR of 1.09 (0.95-1.26, 95%CI) but this difference was not statistically significant. The great heterogenicity in the results reported in the included studies made it impossible to compare all planned outcomes. CONCLUSION: There are no differences in reproductive outcomes if cryopreserved embryos are transferred after overnight culture or after two hours of culture following thawing. Due to small number and the poor quality of trials reported on this topic, the results of this review should be treated with caution.

Oral mini-pulse therapy in vitiligo: a systematic review.

BACKGROUND: There is limited evidence supporting the use of alternative treatments for patients with nonstable vitiligo. OBJECTIVE: This study aimed to review the effects of oral mini-pulse (OMP) therapy in the management of nonsegmental vitiligo. METHODS: The following databases were searched between inception and May 2020 for relevant studies: Scopus, Web of Science, MEDLINE, and Embase. All randomized controlled trials that compared OMP therapy with any other active treatment or placebo for nonstable vitiligo were included. The Cochrane's risk of bias tool was used to evaluate the risk of bias (ROB) in selected studies, and the overall quality of evidence of each outcome was assessed using the Grading Recommendations, Assessment, Development, and Evaluations (GRADE) system. RESULTS: Four studies met our selection criteria. All of them were conducted in India and included 246 patients. OMP therapy included betamethasone or dexamethasone. The duration of treatment was 6 months in all studies. Up to 32% of patients achieved a repigmentation rate of >75% when OMP therapy was administered as monotherapy. No difference was observed between OMP therapy and other treatments in arresting the disease, and weight gain was the most frequent adverse effect. The overall ROB in all included studies was relatively high because of the randomization process, outcome measurement and informed selection of outcomes. CONCLUSION: Based on the findings of these studies, OMP therapy did not demonstrate additional value compared with other treatments. Hence, there is an urgent need to conduct high-quality clinical trials to evaluate this therapy.

Values, preferences and burden of treatment for the initiation of GLP-1 receptor agonists and SGLT-2 inhibitors in adult patients with type 2 diabetes: a systematic review.

OBJECTIVES: Assess values, preferences and burden of treatment that patients with type 2 diabetes consider when initiating glucagon-like peptide-1 receptor agonists (GLP-1 RA) or sodium-glucose cotransporter-2 inhibitors (SGLT-2i) compared with other glucose-lowering options. METHODS: Paired reviewers independently included studies reporting quantitative or qualitative methods to assess values, preferences and burden of treatment reported by patients with type 2 diabetes regarding the initiation of GLP-1 RA or SGLT-2i over other alternatives. A systematic search in MEDLINE, Scopus, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials from inception until May 2020 was performed by an experienced librarian. Risk of bias was assessed with a specifically designed tool for values and preferences studies. RESULTS: 17 studies (7296 patients) proved eligible. Studies fulfilling criteria for SGLT-2i were not identified. Five studies (2662 patients) evaluated preferences for GLP-1 RA compared with other glucose-lowering medications. 12 studies (4634 patients) evaluated preferences between, at least, two kinds of GLP-1 RA or their injection devices based on the following attributes: efficacy, dose, application frequency, device characteristics. Among studies comparing GLP-1 RA to other glucose-lowering medications, some preferences were observed for dypeptil peptidase-4 inhibitors compared with once daily liraglutide. Comparing different attributes of GLP-1 RA drugs and devices, cardiovascular risk reduction, glucose lowering potential, once weekly and simple administered regimens were the most preferred. CONCLUSIONS: As no evidence for preferences on SGLT-2i was available, only preferences for GLP-1 RA were assessed; however, evidence is still limited for the latter. Studies comparing preferences for GLP1-RA to other glucose-lowering alternatives only included twice daily or once daily injection regimens of GLP-1 RA drugs. According to our findings, once weekly alternatives are widely preferred than the formers. The extent to which patients with type 2 diabetes value reduced adverse cardiovascular and kidney outcomes, weighed benefits against harms and burden of treatment is limited and with very low certainty.

Economic impact of Juvenile Idiopathic Arthritis: a systematic review.

BACKGROUND: Juvenile Idiopathic Arthritis (JIA) requires complex care that generate elevated costs, which results in a high economic impact for the family. The aim of this systematic review was to collect and cluster the information currently available on healthcare costs associated with JIA after the introduction of biological therapies. METHODS: We comprehensively searched in MEDLINE, EMBASE, Web of Science, Scopus, and Cochrane Databases for studies from January 2000 to March 2021. Reviewers working independently and in duplicate appraised the quality and included primary studies that report total, direct and/or indirect costs related to JIA for at least one year. The costs were converted to United States dollars and an inflationary adjustment was made. RESULTS: We found 18 eligible studies including data from 6,540 patients. Total costs were reported in 10 articles, ranging from $310 USD to $44,832 USD annually. Direct costs were reported in 16 articles ($193 USD to $32,446 USD), showing a proportion of 55 to 98 % of total costs. Those costs were mostly related to medications and medical appointments. Six studies reported indirect costs ($117 USD to $12,385 USD). Four studies reported costs according to JIA category observing the highest in polyarticular JIA. Total and direct costs increased up to three times after biological therapy initiation. A high risk of reporting bias and inconsistency of the methodology used were found. CONCLUSION: The costs of JIA are substantial, and the highest are derived from medication and medical appointments. Indirect costs of JIA are underrepresented in costs analysis.

Predictors of the length of stay of psychiatric inpatients: protocol for a systematic review and meta-analysis.

BACKGROUND: Length of stay (LOS) for inpatient psychiatric services is an important factor with serious drawbacks when it is extended more than needed. Impacts on economy, social functioning, and stigma can hamper improvement and affect the patients' experiences on future mental healthcare. Predictions of which patients have a higher chance for prolonged LOS have been extensively researched. Previous systematic reviews found consistent predictors of both longer and shorter LOS. However, they do not provide an estimate from the pooled effect sizes. Furthermore, to our knowledge, there is no meta-analysis on the influence of these factors. The primary objective of this study will be to provide point estimates on the effect sizes of all studied predictors of the LOS of psychiatric inpatients. METHODS: We will conduct a systematic search in PubMed, MEDLINE, EMBASE, and PsycINFO for observational studies evaluating the effect size of independent factors on the length of stay of psychiatric inpatients. Prospective and retrospective cohorts that assess the influence of predictors through the reporting of standardized regression coefficients will be included. We will provide a qualitative synthesis of the findings from each study and perform a meta-analysis from pooled regression coefficients that were adjusted for other variables or confounders in order to obtain a point estimate and confidence interval for all factors extracted from the included studies. DISCUSSION: The results from this study may provide more accurate predictions for mental health institutions, psychiatrists, mental health service providers, patients, and families on the prognosis regarding the length of stay for needed inpatient care. This information may be used to anticipate individuals with a higher chance for prolonged hospitalization to plan the necessary interventions for these specific situations. Considering both the benefits and disadvantages of longer and shorter stays, the pooled estimates for independent factors may be used by mental healthcare providers and patients for informed decision-making. The results from this study will also update results presented in previous studies and identify the strengths and limitations from the current available evidence.
