Abstract We identified two homozygous truncating variants in GON4L [NM_001282860.2:c.62_63del, p.(Gln21Argfs*12) and c.5517+1G>A] in two unrelated families who presented prenatal-onset growth impairment, microcephaly, characteristic face, situs inversus, and developmental delay. The frameshift variant is predicted to invoke nonsense-mediated mRNA decay of all five known GON4L isoforms resulting in the complete loss of GON4L function. The splice site variant located at a region specific to the longer isoforms; therefore, defects of long GON4L isoforms may explain the phenotypes observed in the three patients. Knockdown of Gon4l in rat PC12 cells suppressed neurite outgrowth in vitro. gon4lb knockdown and knockout zebrafish successfully recapitulated the patients’ phenotypes including craniofacial abnormalities. We also observed situs inversus in gon4lb-knockout zebrafish embryo. To our knowledge, the relationship between craniofacial abnormalities or situs inversus and gon4lb has not been reported before. Thus, our data provide evidence that GON4L is involved in craniofacial and left-right patterning during development.

Background. Diabetes mellitus is often accompanied by dyslipidemia. Sodium-glucose cotransporter-2 (SGLT2) inhibitors, as a novel therapeutic agent for the treatment of type 2 diabetes mellitus (T2DM), have been reported to exert effects on lipid, while the results remain controversial. This study is aimed at exploring the effect of SGLT2 inhibitor canagliflozin on lipid profile. Methods. This study was a single-center, open-label, nonrandomized, prospective study. Metformin (500 mg three times per day) or canagliflozin (100 mg, once daily) was administered for 12 weeks. Fasting blood samples were collected before and 12 weeks after treatment. Serum lipid profile levels and angiopoietin-like protein 3 (ANGPTL3) were determined. In animal experiment, C57BL/6 J mice were divided into three groups including control, STZ + HFD, and STZ + HFD + canagliflozin. Lipid profile and plasma ANGPTL3 level were measured after 12 week’s treatment. Moreover, the expression of ANGPTL3 was detected in the liver tissues. Results. There was a decreased trend in low-density lipoprotein cholesterol (LDL-c) and triglycerides (TG) after canagliflozin treatment, while canagliflozin significantly increased high-density lipoprotein cholesterol (HDL-c) level and decreased plasma ANGPTL3 level. In addition, the expression of ANGPTL3 in liver tissues decreased obviously in diabetic mice with canagliflozin treatment. Conclusions. Canagliflozin increases HDL-c level and suppresses ANGPTL3 expression in patients with T2DM and diabetic mice. The reduction of ANGPTL3 may contribute to the increase of HDL-c. However, the specific mechanism needs further research. This trial is registered with ChiCTR1900021231.

Prototyping is a core activity in developing new products, processes, and organisations alike. This paper describes the prototyping activities of 31 engineering design professionals in a high-technology industrial company, examining the distribution of different types of activities across different phases of development based on thematic interviews. Examining 62 prototyping and testing pathways, we found that most prototyping paths started with the practitioners’ own activities, which was also more likely to lead to paths with more prototyping steps than if the first prototyping activity took place with a stakeholder. Overall, the paths were short, indicating a lack of iteration. Both internal and external stakeholders were involved in collaborative prototyping. This collaboration was enabled by personal and unit level relationships, and different stakeholders were involved in different phases of development. Taken together, our results suggest that practitioner attention in prototyping may focus on latter development phases and demonstrate less iteration than what literature might suggest, with opportunities for prototyping highly dependent on personal networks in the high-technology context in the absence of flexible prototyping budgets.

# Background Tuberculosis preventive treatment (TPT) in child household contacts is recommended by World Health Organization (WHO) but limited data has been reported on the costs experienced by households with children receiving TPT. # Methods We evaluated the economic impact on households with children receiving TPT within a service-delivery model cluster-randomised controlled trial in Cameroon and Uganda. The intervention included community health worker-led home-based child-contact screening, TPT initiation and monitoring, and referral of children with presumptive tuberculosis or side effects, and was compared with each country's facility-based standard of care (control). We used a retrospective cross-sectional survey adapted from the WHO Global task force on tuberculosis patient cost surveys. All costs were collected between February 2021 and March 2021 and are presented in 2021 US\$. # Results The median household costs estimated using the human capital approach were higher in the control arm (\$62.96 \[interquartile range, IQR; \$19.78-239.74\] in Cameroon and \$35.95 \[IQR; \$29.03-91.26\] in Uganda) compared to the intervention arm (\$2.73 \[IQR; \$2.73-14.18\] in Cameroon and \$4.55 \[IQR; \$3.03-6.06\] in Uganda). Using a threshold of 20% of annual household income, 15% (95%CI; 5-31%) of households in Cameroon and 14% (95%CI; 4-26%) in Uganda experienced catastrophic costs in the control compared to 3% (95%CI; 1- 8%) in Cameroon and 3% (95%CI; 1-8%) in Uganda in the intervention. Using the output-based approach to estimate income losses increased costs by 14-32% in the control and 13-19% in the intervention across the two countries. The proportion of participants experiencing any dissaving was higher in the control, 53% (95%CI; 36-71%) in Cameroon and 50% (95%CI; 31-69%) in Uganda, compared to 18% (95%CI; 10-29%) in Cameroon and 17% (95%CI; 8-28%) in Uganda in the intervention. # Conclusions Households with child contacts initiated on TPT under a facility-based model incur significant costs. Community-based interventions help to reduce these costs but do not eliminate catastrophic expenditures. \ **Registration** https://clinicaltrials.gov/ct2/show/NCT03832023.

The ultrathin oxide nanosheets obtained through previous approaches usually exhibit amorphism or polycrystallinity, which limit their properties towards electronic devices. Here, the authors synthesize ultrathin antimony oxide single crystals with high dielectric constant (~100) and large breakdown voltage (~5.7 GV m−1).

Background. Para and perirenal fat is a fat pad surrounding the kidneys. Recent studies showed the association between para and perirenal fat and cardiovascular diseases including atherosclerosis and hypertension. We aimed to assess the relationship between para-perirenal ultrasonographic fat thickness and serum high-density lipoprotein (HDL) level and cholesterol efflux capacity of HDL in patients with type 2 diabetes mellitus (T2DM). Methods. We recruited 58 subjects with T2DM and collected anthropometric indices including height, weight, waist circumference, and other clinical data. Para-perirenal ultrasonographic fat thickness (PUFT) was measured via ultrasound. Serum lipid profile and other metabolic indices were determined as well. Correlation analysis and regression analysis were performed to analyze the relationship between PUFT and HDL level and cholesterol efflux capacity in all patients and subgroups. Results. Patients with higher PUFT have lower serum HDL level but increased cholesterol efflux capacity. Further analysis showed that PUFT negatively correlated with the serum HDL level in all patients, with no difference in groups divided by body mass index (BMI). In addition, PUFT was positively correlated with cholesterol efflux capacity in all patients. Multiple stepwise regression analysis showed an independent association of PUFT and serum HDL level and cholesterol efflux capacity. Conclusions. PUFT is closely correlated with the serum HDL level and cholesterol efflux capacity in patients with T2DM.

Purpose The Finnish National Esophago-Gastric Cancer Cohort (FINEGO) was established to combine the available registry data with detailed patient information to form a comprehensive, retrospective, population-based research platform of surgically treated oesophageal and gastric cancer in Finland. This cohort profile describes the 2045 surgically treated patients with oesophageal cancer included in the FINEGO cohort.Participants Registry data were collected from the National Cancer, Patient, Education and Death Registries from 1 January 1987 to 31 December 2016. All patients over 18 years of age, who had either curative surgery, palliative surgery or salvage surgery for primary cancer in the oesophagus are included in this study.Findings to date 2045 patients had surgery for oesophageal cancer in the selected time period. 67.2% were man, and the majority had only minor comorbidities. The proportions of adenocarcinomas and squamous cell carcinomas were 43.1% and 44.4%, respectively, and 12.5% had other or missing histology. Only about 23% of patients received neoadjuvant therapy. Oesophagectomy was the treatment of choice and most patients were treated at low-volume centres, but median annual hospital volume increased over time. Median overall survival was 23 months, 5-year survival for all patients in the cohort was 32.9% and cancer-specific survival was 36.5%.Future plans Even though Finland only has a population of 5.5 million, surgery for oesophageal carcinoma has not been centralised and therefore previously reported results have mostly been small, single-centre cohorts. Because of FINEGO, we now have a population-based, unselected cohort of surgically treated patients, enabling research on national trends over time regarding oesophageal cancer, including patient characteristics, tumour histology, stage and neoadjuvant treatment, surgical techniques, hospital volumes and patient mortality. Data collection is ongoing, and the cohort will be expanded to include more detailed data from patient records and national biobanks.

Purpose The Finnish National Esophago-Gastric Cancer Cohort (FINEGO) was established with the aim of identifying factors that could contribute to improved outcomes in oesophago-gastric cancer. The aim of this study is to describe the patients with gastric cancer included in FINEGO.Participants A total of 10 457 patients with gastric cancer or tumour diagnosis in the Finnish Cancer Registry or the Finnish Patient Registry during 1987–2016 were included in the cohort, with follow-up from Causes of Death Registry until 31 December 2016. All of the participants were at least 18 years of age, and had undergone either resectional or endoscopic mucosal surgery with curative or palliative intent.Findings to date Of the 10 457 patients, 90.1% were identified to have cancer in both cancer and patient registries. In all, the median age was 70 at the time of surgery, 54.5% of the patients were men and 64.4% had no comorbidities. Education data were available for 31.1% of the patients, of whom the majority had had

Environmental studies tend to focus on peacetime development. However, people all over the world think that the most important historical event that has taken place over the past century is the Second World War. Could it be worthwhile to explore how the largest violent conflict in human history possibly affected the urban environment? In the following potential impacts of this war on urban development and urban environment are briefly discussed.

Aims. Hashimoto’s thyroiditis (HT), a type of autoimmune disease, occurs due to genetic predisposition and environmental factors. It is well known that thyroid function may affect the gut microbiota. However, the composition of gut microbiota in HT patients with different thyroid function status has been less highlighted. Therefore, we focused on the alterations in the composition of gut microbiota in HT patients with euthyroidism and hypothyroidism. Methods. We performed a cross-sectional study, including 45 HT patients with euthyroidism, 18 HT patients with hypothyroidism, and 34 healthy controls. Fecal samples were collected, and microbiota was examined by using 16S RNA ribosomal RNA gene sequencing. Then, we analyzed the possible pathways in relation to the enriched bacteria by linear discriminant analysis (LDA) effect size (LEfSe). Results. Compared with the controls, bacterial richness and diversity were significantly lower in patients with HT, especially in hypothyroidism. Moreover, Lachnospiraceae_incertae_sedis, Lactonifactor, Alistipes, and Subdoligranulum were more enriched in HT patients with euthyroidism, while Phascolarctobacterium was more abundant in those with hypothyroidism. Further analysis suggested that Phascolarctobacterium was negatively related to several pathways, including environmental information processing and metabolism. Conclusion. In summary, our study demonstrated the altered composition of gut microbiota in HT patients with different thyroid function status. Moreover, Phascolarctobacterium may be involved in the development of HT.

The goal of this study was to determine the prevalence and associated risk factors of impaired glucose regulation (IGR) in the population of Tongzhou, China, and to provide scientific basis for preventive interventions. In the study, the overall age-standardized prevalence of IGR (16.0%) in Tongzhou residents was higher than that in the national population (15.0%). There was no significant geographic difference in prevalence of IGR between urban and rural males. Older age, elevated blood pressure, high serum lipids, overweight, and central obesity were significantly associated with increased risk of IGR.

The WHO recommends shorter TB preventive treatment (TPT) regimens and decentralised delivery models to improve effectiveness. This study evaluated the safety of a 3-month rifampicin-isoniazid (3RH) regimen administered by community health workers (CHWs) in households in Cameroon and Uganda.A cluster-randomised trial was conducted among child contacts of TB patients. We compared the safety of 3RH delivered by CHWs at home (intervention) vs standard-of-care, facility-based administration of 3RH. Safety outcomes included adverse events (AEs), serious adverse events (SAEs), and adverse reactions (ARs). We described the steps from symptom identification by CHWs to classification by a clinician.Of 1,316 children initiated on 3RH, AEs were reported in 8.7% (81/936) in the intervention arm versus 11.3% (43/380) in the standard-of-care arm, P = 0.15. Overall, 37 SAEs occurred in 36 children, all non-medication related. There were 16 ARs reported, occurring in 1.0% (9/936) of children in the intervention arm and 1.6% (6/380) in the standard-of-care arm, P = 0.22. During 4,608 follow-up visits, 21 children reporting AR symptoms were identified by CHWs, 16 were assessed by clinicians, and 4 ARs were confirmed.The 3RH regimen was safe, including when administered by trained CHWs in community settings, supporting its use in decentralised healthcare models..

Despite significant advancements in achieving high recanalization rates (80%-90%) for large vessel occlusions through mechanical thrombectomy, the issue of "futile recanalization" remains a major clinical challenge. Futile recanalization occurs when over half of patients fail to experience expected symptom improvement after vessel recanalization, often resulting in severe functional impairment or death. Traditionally, this phenomenon has been attributed to inadequate blood flow and reperfusion injury. More recently, ongoing neuronal death after reperfusion, which leads to the progression of the ischemic penumbra into the core infarct, has been termed "futile reperfusion." This review explores the complex role of autophagy mechanisms in futile reperfusion following ischemic stroke, with a focus on its relationship to neuronal survival. We also examine the regulation of autophagic activity by epigenetic mechanisms. By investigating autophagy's role in ischemic stroke, we aim to identify novel pathways for precision treatment., (© 2025 Wiley Periodicals LLC.)

Objective: Patients undergoing anterior/posterior lumbar fusion surgery can undergo either a single-stage or multistage operation, depending on surgeon preference. The goal of this study was to assess different patient outcomes between single-stage and multistage lumbar fusion procedures in a multicenter setting., Methods: The Michigan Spine Surgery Improvement Collaborative database was queried for anterior/posterior lumbar fusion surgeries between July 2018 and January 2022. Patients who underwent either single-stage or multistage procedures were included. For multistage procedures, the first surgery included both anterior lumbar interbody fusions and lateral lumbar interbody fusions. Primary outcomes included postoperative complications and improvement in patient-reported outcomes: Patient-Reported Outcomes Measurement Information System Physical Function, EQ-5D, and satisfaction. The two cohorts were propensity score matched, while Poisson generalized estimating equation models were used for multivariate analyses., Results: After one-to-one propensity score matching, 355 patients were identified in the single-stage and multistage cohorts. Single-stage procedures were associated with a lower risk of complications (p = 0.024), fewer emergency department visits (p = 0.029), and higher patient satisfaction after 1 year (p = 0.026) and 2 years (p = 0.007), compared with multistage procedures. After adjusting for baseline patient and operative characteristics, patients undergoing multistage procedures had a higher risk of complications (relative risk [RR] 1.17, 95% CI 1.02-1.34; p = 0.026), were less likely to be satisfied after 1 year (RR 0.83, 95% CI 0.74-0.93; p < 0.001), and were less likely to experience improvement in back pain after 90 days (RR 0.86, 95% CI 0.75-0.99; p = 0.039) and 2 years (RR 0.76, 95% CI 0.60-0.96; p = 0.023)., Conclusions: The authors observed that patients who undergo lumbar fusion surgery using a multistage approach have higher postoperative complication rates and are less likely to report satisfaction compared with a matched, single-stage procedure cohort.

Introduction: Paediatric tuberculosis (TB) underdiagnosis is a critical concern. The INPUT stepped-wedge cluster-randomised trial assessed the impact of integrating child TB services into child healthcare on TB case detection among children under age 5 years., Methods: We compared the standard of care, providing TB care in specific TB clinics (control phase), with the Catalysing Paediatric TB Innovations (CaP-TB) intervention, integrating TB services across all child health services (intervention phase). 12 clusters in Cameroon and Kenya transitioned from the standard of care to the intervention at randomly assigned times. Children with presumptive TB were enrolled after obtaining their parents' consent and were followed throughout TB diagnostic procedures and treatment. Study outcomes included the rate of children with presumptive TB receiving TB investigations and that of children diagnosed with TB (the primary outcome was case detection), per thousand children under 5 years attending facilities. Generalised linear mixed Poisson models estimated the intervention's effect as adjusted rate ratios (aRR) and associated 95% CIs. Ad hoc country-stratified analyses were conducted., Results: During control and intervention phases, respectively, 121 909 and 109 614 children under 5 years attended paediatric entry points, 133 (1.1 per thousand) and 610 (5.6 per thousand) children with presumptive TB received TB investigations, and 79 and 74 were diagnosed with TB, corresponding to a case detection rate of 0.64 and 0.68 per thousand, respectively. CaP-TB significantly increased TB investigations in both countries overall (aRR=3.9, 95% CI 2.4 to 5.4), and in each. Overall, TB case detection was not statistically different between intervention and control (aRR 1.32, 95% CI 0.66 to 2.61, p=0.43). Country-stratified analysis revealed a 10-fold increase (aRR 9.75, 95% CI 1.04 to 91.84, p=0.046) in case detection with CaP-TB in Cameroon and no significant effect in Kenya (aRR 0.94, 95% CI 0.44 to 2.01, p=0.88)., Conclusion: CaP-TB increased TB investigations in both study countries and markedly enhanced TB case detection in one, underlining integrated TB services' potential to address paediatric TB underdiagnosis., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Ticks are important vectors of disease, particularly in the context of One Health, where tick-borne diseases (TBDs) are increasingly prevalent worldwide. TBDs often involve co-infections, where multiple pathogens co-exist in a single host. Patients with chronic Lyme disease often have co-infections with other bacteria or parasites. This study aimed to create a co-infection model with Borrelia afzelii and tick-borne encephalitis virus (TBEV) in C3H mice and to evaluate symptoms, mortality, and pathogen level compared to single infections. Successful co-infection of C3H mice with B. afzelii and TBEV was achieved. Outcomes varied, depending on the timing of infection. When TBEV infection followed B. afzelii infection by 9 days, TBEV symptoms worsened and virus levels increased. Conversely, mice infected 21 days apart with TBEV showed milder symptoms and lower mortality. Simultaneous infection resulted in mild symptoms and no deaths. However, our model did not effectively infect ticks with TBEV, possibly due to suboptimal dosing, highlighting the challenges of replicating natural conditions. Understanding the consequences of co-infection is crucial, given the increasing prevalence of TBD. Co-infected individuals may experience exacerbated symptoms, highlighting the need for a comprehensive understanding through refined animal models. This study advances knowledge of TBD and highlights the importance of exploring co-infection dynamics in host-pathogen interactions., Competing Interests: The authors declare no conflict of interest.

Background: The outbreak of COVID-19 has caused a setback to the gains achieved in tuberculosis (TB) control by impairing TB diagnosis, delaying treatment initiation and aggravating TB deaths. This study explored the effect of COVID-19 on paediatric TB services provided through the Catalysing Paediatric TB Innovations (CaP-TB) project among caregivers of children receiving TB services and healthcare workers (HCWs) providing TB services in Cameroon and Kenya., Methods: From March to September 2021, in-depth interviews (44) were conducted with caregivers whose children under 5 years had gone through TB services and programme managers (10) overseeing the CaP-TB project. Focus group discussions were conducted with HCWs (07) and community health workers (04) supporting TB care services. Transcripts were coded and analysed by using MAXQDA V.12., Results: The COVID-19 pandemic has caused fear and anxiety among HCWs and caregivers. This fear was motivated by stigma related to COVID-19 and affected the ability to screen patients for TB due to the similarity of symptoms with COVID-19. The health-seeking behaviour of patients was affected, as many caregivers avoided hospitals and those accessing the facilities concealed their sickness due to fear of testing positive or being vaccinated. In addition, COVID-19 mitigation strategies implemented by both government and health facilities to curb the spread of the virus limited patient access to paediatric healthcare services. These included temporary closure of health facilities due to COVID-19 infections among staff, transfer of services to other spaces, spacing out patient appointments and reduced time spent with patients., Conclusions: The outbreak of COVID-19 has induced fear and stigma that affected patients' health-seeking behaviour and provider attitudes towards paediatric TB service delivery. In addition, facility and governmental measures put in place to mitigate COVID-19 impact negatively affected paediatric service delivery. Training for health personnel, timely provision of personal protective equipments and appropriate communication strategies could help mitigate COVID-19 impact on paediatric TB service delivery., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Contact tracing was described as a key strategy to contribute to controlling the spread of severe acute respiratory syndrome of Coronavirus 2 (SARS-CoV-2) but implementing it can be a challenge. Digitalisation of contact tracing is among the proposed solutions being explored in sub-Saharan African settings. We assessed the effectiveness of a digital tool to expand SARS-CoV-2 testing in exposed individuals in Cameroon., Methods: We conducted a cluster-randomised (1:1) trial in eight health districts, including 22 facilities and SARS-CoV-2 testing units, randomly assigned to a digital (intervention) or standard (control) contact tracing approach. The intervention consisted of a contact tracing module added to the digital platform "Mamal PRO" used for monitoring and coordination of Coronavirus Disease 2019 pandemic response in Cameroon. The primary outcome was the proportion of contacts declared by SAR-CoV-2 index patients who were successfully traced and tested for SARS-CoV-2 evaluated with a Poisson regression model with cluster adjustment. This study is registered with ClinicalTrials.gov (NCT05684887)., Findings: Between October 18, 2022, and March 31, 2023, we enrolled 164 index patients in the intervention arm and 149 in the control arm, who identified 854 and 849 contacts, respectively. In the intervention arm, 93.8% (801/854) of identified contacts were successfully reached by the tracing unit versus 54.5% (463/849) in the control arm. The intervention significantly increased the likelihood of successfully tracing contacts (adjusted relative risks (RR) 1.72 [95% CI: 1.00-2.95], p = 0.049). The median (interquartile range, IQR) time to successfully tracing contacts was 0 days [IQR: 0, 1] in the intervention and 1 day [IQR: 0, 2] in the control arm. In the intervention arm, 21.3% (182/854) of identified contacts received SARS-CoV-2 testing compared to 14.5% (123/849) in the control arm (adjusted RR 1.47 [95% CI: 0.44-4.90], p = 0.530)., Interpretation: Digitalising the contact tracing process improved exposure notification and facilitated the tracing of a greater number of contacts of individuals infected with SARS-CoV-2 in resource-limited settings., Funding: The study was funded by FIND, United Kingdom (FCDO 40105983), Switzerland (81066910), Netherlands (SDD 4000004160), Canada (DFATD 7429348), The Kingdom of Saudi Arabia (FIND-ACT-A DX PARTNERSHIP 20.08.2020), The Rockefeller Foundation (2020 HTH 059), Germany (BMZ Covid-19 Diagnostic and Surveillance Response 27.07.2021), Australia (DFAT 76442), Kuwait (M239/2020), The Government of Portugal and Partners (ANF, BCP, CGF, APIFARMA) and The BlackRock Foundation (Grant Agreement as of April 20, 2022)., Competing Interests: BKT has received support from FIND (through funding for the AFCON grant paid to his institution) to participate to a meeting on operational research in Kigali and the CPHIA conference.

Introduction: People living with HIV are considered at higher risk of developing severe forms of tuberculosis (TB) disease. Providing HIV testing to TB-exposed people is therefore critical. We present the results of integrating HIV testing into a community-based intervention for household TB contact management in Cameroon and Uganda., Methods: Trained community health workers visited the households of index patients with TB identified in 3 urban/semiurban and 6 rural districts or subdistricts as part of a cluster-randomized trial and provided TB screening to all household contacts. Voluntary HIV counseling and testing were offered to contacts aged 5 years or older with unknown HIV status. We describe the cascade of care for HIV testing and the factors associated with the acceptance of HIV testing., Results: Overall, 1983 household contacts aged 5 years or older were screened for TB. Of these contacts, 1652 (83.3%) did not know their HIV status, 1457 (88.2%) accepted HIV testing, and 1439 (98.8%) received testing. HIV testing acceptance was lower among adults than children [adjusted odds ratio (aOR) = 0.35, 95% confidence interval (CI): 0.22 to 0.55], those living in household of an HIV-positive vs HIV-negative index case (aOR = 0.56, 95% CI: 0.38 to 0.83), and contacts requiring a reassessment visit after the initial TB screening visit vs asymptomatic contacts (aOR = 0.20, 95% CI: 0.06 to 0.67) and was higher if living in Uganda vs Cameroon (aOR = 4.54, 95% CI: 1.17 to 17.62) or if another contact of the same index case was tested for HIV (aOR = 9.22, 95% CI: 5.25 to 16.18)., Conclusion: HIV testing can be integrated into community-based household TB contact screening and is well-accepted., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 The Author(s).

Herein, we present the first examples of amino acid decarboxylation via photochemically activated carbonyl sulfide (COS) elimination of the corresponding thioacids. This method offers a mild approach for the decarboxylation of amino acids, furnishing N -alkyl amino derivatives. The methodology was compatible with amino acids displaying both polar and hydrophobic sidechains and was tolerant towards widely used amino acid-protecting groups. The compatibility of the reaction with continuous-flow conditions demonstrates the scalability of the process., Competing Interests: The authors declare no conflicts of interest.

Background and Objectives: Diabetes mellitus is associated with increased risk of postoperative adverse outcomes. Previous studies have emphasized the role of glycemic control in postoperative complications. This study aims to ascertain whether controlling hemoglobin A1c (HbA1c) lower than 8% preoperatively results in meaningful risk reduction or improved outcomes., Methods: We used patient-level data from the Michigan Spine Surgery Improvement Collaborative registry, focusing on patients who underwent elective lumbar spine surgery between 2018 and 2021. The primary outcomes were length of stay and the occurrence of postoperative adverse events. Secondary outcomes included patient satisfaction, achievement of a minimum clinically important difference (MCID) of Patient-Reported Outcomes Measurement Information System-Physical Function, the EuroQol-5D and NRS of leg and back pain, and return to work., Results: A total of 11 348 patients were included in this analysis. Patients with HbA1c above the thresholds before surgery had significantly higher risks of urinary retention for all 3 possible threshold values (incidence rate ratio [IRR] = 1.30, P = .015; IRR = 1.35, P = .001; IRR = 1.25, P = .011 for the HbA1c cutoffs of 8%, 7.5%, and 7%, respectively). They also had longer hospital stay (IRR = 1.04, P = .002; IRR = 1.03, P = .001; IRR = 1.03, P < .001 for the HbA1c cutoffs of 8%, 7.5%, and 7%, respectively) and had higher risks of developing any complication with HbA1c cutoff of 7.5% (IRR = 1.09, P = .010) and 7% (IRR = 1.12, P = .001). Diabetics with preoperative HbA1c above all 3 thresholds were less likely to achieve Patient-Reported Outcomes Measurement Information System MCID at the 90-day follow-up (IRR = .81, P < .001; IRR = .86, P < .001; IRR = .90, P = .007 for the HbA1c cutoffs of 8%, 7.5%, and 7%, respectively) and less likely to achieve EuroQol-5D MCID at the 2-year follow-up (IRR = .87, P = .027; IRR = .84, P = .005 for the HbA1c cutoffs of 7.5% and 7%, respectively)., Conclusion: Our study suggests that reducing HbA1c below 8% may have diminishing returns regarding reducing complications after spine surgery., (Copyright © Congress of Neurological Surgeons 2024.
