Changes in cAMP-dependent coupling of the Ca2+ and M clocks, caused by a pharmacological intervention that either activates the β-adrenergic or cholinergic receptor or upregulates/downregulates PKA signaling, affected LCR properties, which in turn altered hiPSC-CMs automaticity. Clocks' uncoupling by attenuating the pacemaker current If or the sarcoplasmic reticulum Ca2+ kinetics, decreased hiPSC-CMs beating rate, and prolonged the LCR period. Finally, LCR characteristics of spontaneously beating (at comparable rates) hiPSC-CMs and rabbit SAN are similar. In conclusion, hiPSC-CM automaticity is controlled by the coupled-clock system whose function is mediated by Ca2+-cAMP-PKA signaling.During Ramadan, Muslims fast from dawn to dusk for the duration of the month. The current literature focuses on adults who fast, with little attention to pediatric practices. An anonymous, digital survey was conducted using Qualtrics software and distributed to residents, fellows, or attendings in Michigan in 2019. Overall, 278 participants were included in the analysis, with 87% (242/278) identifying as pediatric trained physicians. In all, 82% (228/278) of physicians identified as non-Muslim and 76% (211/278) had never partaken in the Muslim fast. About 52% (141/273) of participants had at least a moderate amount of exposure to Muslim pediatric patients in their clinical practice. Most physicians (66%; 175/265) reported they never asked their pediatric patients or their families about fasting. About 61% (167/273) of participants rated their understanding of fasting as minimal to none. Another 52% (142/273) of participants reported feeling somewhat or extremely uncomfortable discussing fasting recommendations with their pediatric patients and their families. Our study is the first of its kind in assessing current knowledge and practice regarding pediatric Muslim fasting among physicians in the United States. In addition, it highlights a gap in physicians' understanding and comfort in providing anticipatory guidance for their Muslim patients.Rates of overweight and obesity are problematic among systematically marginalized youth; however, these youth and their families are a hard-to-reach research population. The purpose of our study was to identify facilitators and barriers for recruiting systematically marginalized families in youth weight-management intervention research. This study built upon existing evidence through involvement of youth, parents, community agency workers, and school nurses, and an exploration of both recruitment materials and processes. Seven focus groups were conducted with 48 participants from 4 stakeholder groups (youth, parents, school nurses, and community agency workers). A codebook approach to thematic analysis was used to identify key facilitator and barrier themes related to recruitment materials and processes across the stakeholder groups. Ecological systems theory was applied to contextualize the facilitators and barriers identified. Participants reported the need to actively recruit youth in the study through engaging, fun recruitment materials and processes. Participants reported greater interest in recruitment at community-based events, as compared to recruitment through health care providers, underscoring the depth of distrust that this sample group has for the health care system. Recommendations for recruitment materials and processes for weight-management intervention research with systematically marginalized families are proposed.Despite concerns about negative neurocognitive effects of in utero substance exposure on child and brain development, research in this area is limited. This study gathered perspectives of persons with lived experience of substance use (eg, alcohol, prescription and illicit opioids, and other illicit substances) during a previous pregnancy to determine facilitators and barriers to research engagement in this vulnerable population. We conducted structured, in-depth, individual interviews and 2 focus groups of adult persons with lived experience of substance use during a previous pregnancy. Questions were developed by clinical, research, bioethics, and legal experts, with input from diverse stakeholders. They inquired about facilitators and barriers to research recruitment and retention, especially in long-term studies, with attention to bio-sample and neuroimaging data collection and legal issues. Interviews and focus groups were audio-recorded, transcribed, and analyzed using inductive coding qualitative analysis methods. Ten participants completed in-depth interviews and 7 participated in focus groups. Three main themes emerged as potential barriers to research engagement shame of using drugs while pregnant, fear of punitive action, and mistrust of health care and research professionals. Facilitative factors included trustworthiness, compassion, and a nonjudgmental attitude among research personnel. Inclusion of gender-concordant recovery peer support specialists as research team members was the most frequently identified facilitator important for helping participants reduce fears and bolster trust in research personnel. In this qualitative study, persons with lived experience of substance use during a previous pregnancy identified factors critical for engaging this population in research, emphasizing the involvement of peer support specialists as research team members.Legacy and emerging per- and polyfluoroalkyl substances (PFAS) have attracted growing attention due to their potential adverse effects on humans. We developed a method to simultaneously determine thirty-three PFAS (legacy PFAS, precursors, and alternatives) in human plasma and serum using solid phase extraction coupled to ultra-performance liquid chromatography-tandem mass spectrometry (SPE-UPLC-MS/MS). The method yielded good linearity (>0.995) and excellent limits of detection (LODs) (0.0005~0.012 ng mL-1 in plasma and 0.002~0.016 ng mL-1 in serum). The relative recoveries ranged from 80.1 to 116%, with intra- and inter-day precision less than 14.3%. The robustness of this method has been tested continuously for 10 months (coefficients of variation less then 14.9%). Our method was successfully applied to the PFAS analysis of 42 real human plasma and serum samples collected from women. The proposed method is attractive for the biomonitoring of multi-class PFAS in human health risk assessment and epidemiological studies.
Midshaft clavicle fractures are common, and the proportion of patients treated surgically has increased in recent years. With this increase in surgical treatments, the complication rate, for instance of infection, non-union, or implant failure, has also risen. This study evaluates the frequency of pathogen detection during revision surgeries occurring after a prior failed osteosynthesis of midshaft clavicle fractures.
All patients treated in our hospital with a prior failed surgical therapy of a clavicle midshaft fracture between January 2013 and March 2022 were screened. Epidemiological data, intraoperative tissue samples, sonication, and the type of revision surgery were assessed. A postoperative follow-up at a minimum of 6month was defined and osseous consolidation was verified.
Twenty-one patients (twelve male and eight female) were included with a mean age of 40.4 ± 14.1years. Eleven of the patients showed pathogen detection (Group I), and seven remained without (Group II). A significant difference in age existed between Groups I and II (36.1 ± 12.8 and 51.6 ± 11.5, p ≤ 0.05). The three most common pathogens were Cutibacterium acnes (n = 7), Staphylococcus epidermidis (n = 4), and Staphylococcus sacchorlyticus (n = 3), respectively. Thirteen patients presented for a follow-up. In nine patients (69%), bone healing was detectable. Four patients received a second revision surgery.
Revision surgery frequently shows pathogen detection without signs of infection. Cutibacterium acnes is the most common pathogen. Despite pathogen detection, bone healing can be achieved with revision surgery, although the rate of repeat revision surgeries is high.

There is currently no consensus on nonoperative management in adult patients after a stable type B ankle fracture. The aim of this review is to compare a removable orthosis versus a cast regarding safety and functional outcome in the NOM of stable type B ankle fractures.
A systematic review and meta-analysis were performed using randomized clinical trials and observational studies. The methodological quality of the included studies was assessed with the methodological index for non-randomized studies instrument. Nonoperative management was compared using the number of complications and functional outcome measured using the Olerud and Molander Score (OMAS) or the American Academy of Orthopaedic Surgeons Ankle Score.
Five studies were included. Two were randomized clinical trials, and three were observational studies, including a total of 516 patients. A meta-analysis showed statistically significant higher odds of developing complications in the cast group [odds ratio (OR), 4.67 (95% confidence interval nificantly lower in the orthosis group. In addition, no statistically significant differences were found in terms of functional outcome between a removable orthosis and a cast at 6 and 12 weeks. The 6-week and the 26-week OMAS results show that in patients with stable type B ankle fractures, a removable orthosis is non-inferior to a cast in terms of functional outcome.
There is concern that the COVID-19 pandemic may cause people to refrain from undergoing examination resulting in delayed detection of colorectal cancer (CRC). The purpose of this study was to investigate whether there was a delay in CRC detection due to withholding of screening.
The colonoscopy screening rate and the CRC detection rate were calculated for patients who underwent fecal immunochemical tests (FITs) from 2018 to 2021 in the longitudinal cohort. The stages of CRC cases detected as a result of positive FIT in each year were compared.
A total of 39,521 patients were initially screened by FIT over a 4-year period. The FIT-positive rate was 4.7% (441 /9,349) in 2018, 4.6% (420 /9,156) in 2019, 4.9% (453 /9,255) in 2020, and 4.3% (504 /11,760) in 2021. The colonoscopy screening rate for positive FIT results was lower in 2020 than in 2019 (25.8% vs. Selleck AOA hemihydrochloride 38.1%, P < 0.001), and higher in 2021 than in 2020 (56.7% vs. 25.8%, P < 0.001). The CRC detection rate among colonoscopy recipients was higher in 2021 than in 2020 (13% vs. 4%, P = 0.014). Stage 1 or higher CRC accounted for 25.0% (1/4) in 2020, and 78% (18/23) in 2021. Among the CRC cases detected each year, 1 (14%), 1 (25%), and 10 (43%) did not undergo colonoscopy despite positive FIT results in the previous year.
The COVID-19 pandemic has reduced the detection of CRC by screening colonoscopy following FIT and might have led to a delay in the detection of CRC.
