ABSTRACT

BACKGROUND: Popular web-based portals provide free and convenient access to user-generated hospital quality reviews. The Centers for Medicare & Medicaid Services (CMS) also publishes Hospital Compare Star Ratings (HCSR), a comprehensive expert rating of US hospital quality that aggregates multiple measures of quality. CMS revised the HCSR methods in 2021. It is important to analyze the degree to which web-based ratings reflect expert measures of hospital quality because easily accessible, crowdsourced hospital ratings influence consumers’ hospital choices.

OBJECTIVE: This study aims to assess the association between web-based, Google hospital quality ratings that reflect the opinions of the crowd and HCSR representing the wisdom of the experts, as well as the changes in these associations following the 2021 revision of the CMS rating system.

METHODS: We extracted Google star ratings using the Application Programming Interface in June 2020. The HCSR data of April 2020 (before the revision of HCSR methodology) and April 2021 (after the revision of HCSR methodology) were obtained from the CMS Hospital Compare website. We also extracted scores for the individual components of hospital quality for each of the hospitals in our sample using the code provided by Hospital Compare. Fractional response models were used to estimate the association between Google star ratings and HCSR as well as individual components of quality (n=2619).

RESULTS: The Google star ratings are statistically associated with HCSR (P<.001) after controlling for hospital-level effects; however, they are not associated with clinical components of HCSR that require medical expertise for evaluation such as safety of care (P=.30) or readmission (P=.52). The revised CMS rating system ameliorates previous partial inconsistencies in the association between Google star ratings and quality component scores of HCSR.

CONCLUSIONS: Crowdsourced Google star hospital ratings are informative regarding expert CMS overall hospital quality ratings and individual quality components that are easier for patients to evaluate. Improvements in hospital quality metrics that require expertise to assess, such as safety of care and readmission, may not lead to improved Google star ratings. Hospitals can benefit from using crowdsourced ratings as timely and easily available indicators of their quality performance while recognizing their limitations and biases.

ABSTRACT

Objective: The objective of the study was to determine the effect of task-oriented training on the dexterous movements of hands in Hemiplegic post-stroke patients.Methods: This study has been registered on site ClinicalTrial.gov with clinical trial number NCT05201196. The study was Randomized controlled trial, 18 patients were recruited that meet the inclusion criteria, randomly allocated to task-oriented training Group A (n = 9) and Conventional Therapy Group B (n = 9). Both exercise trainings were applied for 45 min/session, 5 times/week for 6 weeks. Fugl-Meyer Assessment Scale Motor, sensory and coordination portion, Wolf Motor Function Scale and Barthel Index were used as outcome measures, assessed patients at Baseline, after 3 weeks and 6 weeks after training. Data were analyzed by SPSS version 23.Results: The results suggested the mean Age was 60.78 ± 9.08 and 61.33 ± 6.78 for Group A and Group B, respectively. Average BMI was 23.66 ± 2.66 for Task-oriented group and 21.36 ± 2.46 for Conventional group. Fugl-Meyer scale shows significant P-value 0.03 post treatment compare to pre-treatment which was .283, Wolf Motor Function test and Barthel Index also showed significant P-values as 0.023 and 0.007, respectively, indicating that Task-oriented training shows more significant improvements than conventional group.Conclusion: Task-based training produced statistically significant as well as clinically meaningful enhancement in the dexterous hand movements of acute and subacute stroke patients than conventional therapy and ultimately improves the functional independence in their daily activities such as feeding, bathing and hygiene.

ABSTRACT

IMPORTANCE: People conceived using assisted reproductive technology (ART) make up an increasing proportion of the world’s population.

OBJECTIVE: To investigate the association of ART conception with offspring growth and adiposity from infancy to early adulthood in a large multicohort study.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study used a prespecified coordinated analysis across 26 European, Asia-Pacific, and North American population-based cohort studies that included people born between 1984 and 2018, with mean ages at assessment of growth and adiposity outcomes from 0.6 months to 27.4 years. Data were analyzed between November 2019 and February 2022.

EXPOSURES: Conception by ART (mostly in vitro fertilization, intracytoplasmic sperm injection, and embryo transfer) vs natural conception (NC; without any medically assisted reproduction).

MAIN OUTCOMES AND MEASURES: The main outcomes were length / height, weight, and body mass index (BMI; calculated as weight in kilograms divided by height in meters squared). Each cohort was analyzed separately with adjustment for maternal BMI, age, smoking, education, parity, and ethnicity and offspring sex and age. Results were combined in random effects meta-analysis for 13 age groups.

RESULTS: Up to 158 066 offspring (4329 conceived by ART) were included in each age-group meta-analysis, with between 47.6% to 60.6% females in each cohort. Compared with offspring who were NC, offspring conceived via ART were shorter, lighter, and thinner from infancy to early adolescence, with differences largest at the youngest ages and attenuating with older child age. For example, adjusted mean differences in offspring weight were -0.27 (95% CI, -0.39 to -0.16) SD units at age younger than 3 months, -0.16 (95% CI, -0.22 to -0.09) SD units at age 17 to 23 months, -0.07 (95% CI, -0.10 to -0.04) SD units at age 6 to 9 years, and -0.02 (95% CI, -0.15 to 0.12) SD units at age 14 to 17 years. Smaller offspring size was limited to individuals conceived by fresh but not frozen embryo transfer compared with those who were NC (eg, difference in weight at age 4 to 5 years was -0.14 [95% CI, -0.20 to -0.07] SD units for fresh embryo transfer vs NC and 0.00 [95% CI, -0.15 to 0.15] SD units for frozen embryo transfer vs NC). More marked differences were seen for body fat measurements, and there was imprecise evidence that offspring conceived by ART developed greater adiposity by early adulthood (eg, ART vs NC difference in fat mass index at age older than 17 years: 0.23 [95% CI, -0.04 to 0.50] SD units).

CONCLUSIONS AND RELEVANCE: These findings suggest that people conceiving or conceived by ART can be reassured that differences in early growth and adiposity are small and no longer evident by late adolescence.

ABSTRACT

IMPORTANCE: Effective methods for engaging clinicians in continuing education for learning-based practice improvement remain unknown.

OBJECTIVE: To determine whether a smartphone-based app using spaced education with retrieval practice is an effective method to increase evidence-based practice.

DESIGN, SETTING, AND PARTICIPANTS: A prospective, unblinded, single-center, crossover randomized clinical trial was conducted at a single academic medical center from January 6 to April 24, 2020. Vanderbilt University Medical Center clinicians prescribing intravenous fluids were invited to participate in this study.

INTERVENTIONS: All clinicians received two 4-week education modules: 1 on prescribing intravenous fluids and 1 on prescribing opioid and nonopioid medications (counterbalancing measure), over a 12-week period. The order of delivery was randomized 1:1 such that 1 group received the fluid management module first, followed by the pain management module after a 4-week break, and the other group received the pain management module first, followed by the fluid management module after a 4-week break.

MAIN OUTCOMES AND MEASURES: The primary outcome was evidence-based clinician prescribing behavior concerning intravenous fluids in the inpatient setting and pain medication prescribing on discharge from the hospital.

RESULTS: A total of 354 participants were enrolled and randomized, with 177 in group 1 (fluid then pain management education) and 177 in group 2 (pain management then fluid education). During the overall study period, 16 868 questions were sent to 349 learners, with 11 783 (70.0%) being opened: 10 885 (92.4%) of those opened were answered and 7175 (65.9%) of those answered were answered correctly. The differences between groups changed significantly over time, indicated by the significant interaction between educational intervention and time (P = .002). Briefly, at baseline evidence-concordant IV fluid ordered 7.2% less frequently in group 1 than group 2 (95% CI, -19.2% to 4.9%). This was reversed after training at 4% higher (95% CI, -8.2% to 16.0%) in group 1 than group 2, a more than doubling in the odds of evidence-concordant ordering (OR, 2.56, 95% CI, 0.80-8.21). Postintervention, all gains had been reversed with less frequent ordering in group 1 than group 2 (-9.5%, 95% CI, -21.6% to 2.7%). There was no measurable change in opioid prescribing behaviors at any time point.

CONCLUSIONS AND RELEVANCE: In this randomized clinical trial, use of smartphone app learning modules resulted in statistically significant short-term improvement in some prescribing behaviors. However, this effect was not sustained over the long-term. Additional research is needed to understand how to sustain improvements in care delivery as a result of continuous professional development at the institutional level.

ABSTRACT

PURPOSE: Early-onset scoliosis (EOS) is one of the most challenging areas of orthopedic management. Previous studies have reported that EOS patients were associated with high risk of complications following growth-friendly surgery. This study was performed to evaluate the complications of single traditional growing rods (TGRs) in the treatment of EOS.

METHODS: In a retrospective chart review study, medical records of all EOS patients treated with single TGRs between 2006 and 2018 were analyzed. Patients under the age of 10 at the time of surgery who had at least 24 months of follow-up were included. Intra- and post-operative complications included both device-related and disease-related complications. Statistical analysis was performed with SPSS.

RESULTS: A total of 35 patients with a mean age of 5.7 ± 2.1 years with the mean follow-up duration of 33.3 ± 9.1 months were included in the final analysis. Of the 35 participants, 27 children (77.1%) experienced at least one complication. A total of 61 complications were observed, giving rise to 1.7 complications per patient. An unplanned surgical procedure was needed to manage 42 of the 61 complications (68.8%). Thirty-five cases of implant failure, 11 cases of deep infection, and 2 cases of junctional kyphosis were identified.

CONCLUSION: It seems that even in the setting that the use of dual TGRs is not possible, the use of single TGRs as the only therapeutic modality should be minimized due to high rate of complications even as a bridge treatment.

LEVEL OF EVIDENCE: Therapeutic level III.

ABSTRACT

From the very beginning of the SARS-CoV-2 pandemic, one of the very few common opinions was that to control the expansion of the virus as many as the possible test had to be done. Antigen tests, being affordable and easy and fast to use, represented a great opportunity to expand the testing capacities of many healthcare systems. However, in 2021 with the appearance of the new SARS-CoV-2 variants, variant tracking strategies had to be implemented, which often included needing a second test to determine the variant of the patients diagnosed with antigen tests or not taking these samples into consideration at all. Therefore, we proposed recovering the positive antigen test devices to include them in our routine variant tracking strategy. The recovered positive antigen test devices obtained from 1st April 2021 to 15the January 2022 were analysed following the variant tracking protocol in force. The results obtained were compared to the positive samples detected by RT-PCR which were processed for variant tracking during the same period. 21,304 samples were processed, 6297 from the recovered positive antigen devices and 15,007 from the standard nasopharyngeal swabs. Only 773 (3.63%) samples were no conclusive, 104 (1.65%) from the recovered antigen devices and 669 (4.46%) from the RT-PCR positive group. This difference was statistically significant (p < 0.01). Taking this into account the proposed method is suitable and very recommendable, as it is an important measure to have a better and immediate picture of the circulating variants in every community.

ABSTRACT

By reference to a sample of 173 emerging adult seminarians in South Italy, this study evaluates the influence of attachment to one’s parents and peers on identity development and well-being in seminarians. The statistical analysis (PLS-PM) reports that secure attachment to one’s mother and secure attachment to a peer are positively associated with identity and well-being. No such association is found with attachment to one’s father. Attachment to one’s mother loses its association with identity during the shift from the freshmen to the senior group and is replaced by attachment with one’s peers. Both attachment relationships lose their associations with well-being between these groups. Our results demonstrate that attachment to one’s peers becomes the most relevant relationship, thus supporting this specific form of relationship among seminarians.

ABSTRACT

Chronic nasal carriage of Staphylococcus aureus (S. aureus) is a risk factor for relapse of granulomatosis with polyangiitis (GPA), and genetic susceptibility to infections and autoimmune diseases is majorly affected by HLA genes. Previous studies have shown the association of HLA Class-II genes with GPA susceptibility. Here, we aim to assess immune responses of GPA patients against S. aureus antigens in relation to the HLA-DR-DQ genes polymorphism to determine the disease outcome. A total of 45 GPA patients and 128 healthy controls during 2010-2012 were included in this case-control study. HLA-DRB1/DQB1 allele typing was performed by polymerase chain reaction-sequence-specific primer (PCR-SSP) method. Immune responses against S. aureus antigens were investigated in 20 active vs. remitting GPA (after 6 months of cyclophosphamide and glucocorticoids) patients by Western blot. Statistical analysis was performed using χ² test and Fisher’s exact test. We observed a significant association of DRB1*08, DRB1*16 and DQB1*04 alleles with GPA susceptibility, whereas DRB1*15, DRB1*10 and DQB1*05 alleles were suggested as protective alleles. Among S. aureus antigens, active GPA patients’ sera reacted more strongly with 34 and 24 kDa antigens of S. aureus than remitting and healthy control sera. Furthermore, we observed that the lack of DQB1*06 allele confers complete remission even in the presence of anti-S. aureus antibodies against 24 kDa protein. Our findings suggest that the presence of DQB1*06 allele and S. aureus infection may prolong active disease. Further, our study indicates the potential of using anti-staphylococcal medications for achieving remission in patients having HLA-DQB1*06 allele.

ABSTRACT

Although many studies have examined reasons for sexting among young people, few have taken into account the underlying motivations associated with different reasons and how that may be associated with divergent positive or negative outcomes. This study addressed this gap by employing Self-determination Theory to assess how autonomous and controlled motivations for sexting were related to subjective well-being and relationship quality among emerging adults. Online survey data from 267 emerging adults (72 men, 195 women) ages 18-25 who had sent sexually explicit images or videos of themselves through electronic means to a committed partner were analyzed using Structural Equation Modeling. Autonomous and controlled motivations for sexting were significantly related to pleasant affect, with autonomous motivation predicting more pleasant affect and controlled motivation predicting less pleasant affect. Autonomous motivations for sexting were related to enhanced relationship quality, whereas controlled motivations for sexting were related to decreased relationship quality. Neither form of motivation had a statistically significant relationship with unpleasant affect or life satisfaction. These results demonstrate that the quality of motivations for sexting among emerging adults in committed relationships may contribute to different outcomes, particularly in terms of relationship quality. Implications for counselors, educators, and practitioners working with emerging adults who sext are discussed.

ABSTRACT

The present meta-analysis provides literature data on the effect of lichen extracts and single secondary metabolites used against Fusarium spp. moulds. Lichen extracts were obtained from 51 corticolous, 17 terricolous and 18 saxicolous lichen species and 37 secondary compounds were tested against eight fungal species, i.e., Fusarium acuminatum, F. avenaceum, F. culmorum, F. fujikuroi, F. oxysporum, F. roseum, F. solani and F. udum. The researchers used several test methods, mostly to determine MIC and IZ. Extracts were obtained using several solvents, mainly organic ones with use of the Soxhlet apparatus. The most frequently tested species was F. oxysporum, against which lichen substances from Alectoria sarmentosa, Cladonia mitis, C. rangiferina, Flavoparmelia caperata, Hypotrachyna cirrhata, Leucodermia leucomelos, Parmotrema austrosinense, P. reticulatum, Physcia aipolia, Pseudevernia furfuracea, Roccella montagnei and Umbilicaria nylanderiana and secondary metabolites such as 2-hydroxy-4-methoxy-3,6-dimethylbenzoic acid, atranorin, lecanoric and (+)-usnic acids showed the highest antifungal potential. These agencies could compete with the potential of fungicides, such as flucytosine and fluconazole. Other species have been poorly investigated. Statistical analysis of literature data showed that the fungistatic potential of lichen extracts is significantly different from individual secondary metabolites. Similarly, the potential of secondary metabolites often differs significantly from that of non-lichen substances. This meta-analysis indicates the potential of lichen substances as future anti-fusarial agents.
