Doctor simulator: Delta-Age-Sex-AdaIn enhancing bone age assessment through AdaIn style transfer.

Bone age assessment assists physicians in evaluating the growth and development of children. However, deep learning methods for bone age estimation do not currently incorporate differential features obtained through comparisons with other bone atlases. To propose a more accurate method, Delta-Age-Sex-AdaIn (DASA-net), for bone age assessment, this paper combines age and sex distribution through adaptive instance normalization (AdaIN) and style transfer, simulating the process of visually comparing hand images with a standard bone atlas to determine bone age. The proposed Delta-Age-Sex-AdaIn (DASA-net) consists of four modules: BoneEncoder, Binary code distribution, Delta-Age-Sex-AdaIn, and AgeDecoder. It is compared with state-of-the-art methods on both a public Radiological Society of North America (RSNA) pediatric bone age prediction dataset (14,236 hand radiographs, ranging from 1 to 228 months) and a private bone age prediction dataset from Zigong Fourth People's Hospital (474 hand radiographs, ranging from 12 to 218 months, 268 male). Ablation experiments were designed to demonstrate the necessity of incorporating age distribution and sex distribution. The DASA-net model achieved a lower mean absolute deviation (MAD) of 3.52 months on the RSNA dataset, outperforming other methods such as BoneXpert, Deeplasia, BoNet, and other deep learning based methods. On the private dataset, the DASA-net model obtained a MAD of 3.82 months, which is also superior to other methods. The proposed DASA-net model aided the model's learning of the distinctive characteristics of hand bones of various ages and bothsexes by integrating age and sex distribution into style transfer.

Awareness of rhinoplasty surgery among the population in the Jazan Region, Saudi Arabia.

Cosmetic and plastic surgery is becoming increasingly prevalent all over the world among both men and women. Saudi Arabia ranks 22nd among the top 25 countries with the world's highest rates of cosmetic surgeries. This study aimed to assess the awareness of the population in the Jazan region regarding rhinoplasty surgery and to identify their main determinants. A cross-sectional study of 425 participants was conducted at four randomly selected malls in Gizan City. A self-administered questionnaire was first developed to collect the data necessary to fulfill the research objectives, data were analyzed using Statistical Package for the Social Sciences (SPSS) version 22. The quantitative data were reported as a mean and standard deviation, and the qualitative data were reported as frequency and percentage. Regarding tests for significance, the Chi-square test used a P value less than 0.05 as an indicator of significance. Logistic regression was used to detect the predictors of poor knowledge of rhinoplasty surgery. The mean age of the participants was 39.46 ± 10.08. Of the participants, 53.6% have poor knowledge while 36.0% have good knowledge regarding rhinoplasty surgery. Moreover, 60.2% have an unfavorable attitude while 23.6% have a favorable attitude toward rhinoplasty surgery. The most important predictors of poor knowledge of rhinoplasty surgery are as follows: (a) old age (OR = 4.89), (b) illiteracy (OR = 4.12), (c) intermediate education (OR = 3.65), and (d) male sex (OR = 1.18). There was a low level of knowledge regarding rhinoplasty surgery among the study participants, most of the participants had negative (unfavorable) attitudes toward rhinoplasty surgery. Mass media plays an important role as a source of information. We recommend further studies to find out other personal factors affecting knowledge and attitude toward rhinoplasty surgery.

The significance of neuroendocrine component in cases with intrahepatic cholangiocarcinoma: A SEER-based retrospective cohort study

ObjectiveTo evaluate the significance of neuroendocrine component in cases with intrahepatic cholangiocarcinoma (IHCC). MethodsCases with IHNECA and IHBDAC from the Surveillance, Epidemiology, and End Results (SEER) database were retrospectively reviewed and analyzed. Comparative analyses in terms of clinic-pathological features and long-term survival were performed between cases with intrahepatic neuroendocrine carcinoma (IHNECA) and intrahepatic bile duct adenocarcinoma (IHBDAC). ResultsA total of 5211 cases with IHCC were included (103 with IHNECA and 5108 with IHBDAC). Comparable age status (P=0.168), sex status (P=0.274), and cirrhosis status (P=0.480) were acquired between two groups while inconsistent distributions in races (P=0.027) and marital status (P=0.028) were also acquired. Cases with IHBDAC were generally in a more advanced stage and shared a worse prognosis. A significantly higher incidence of lymph node metastasis was detected among cases with IHBDAC (24.8% vs 15.5%, P=0.031). Although the overall surgery rate was comparable between two groups (P=0.519), chemotherapy (53.0% vs 37.9%, P=0.002) and radiotherapy (6.0% vs 1.0%, P=0.032) were more frequently performed with a much higher cancer-related death (CRD) (79.4% vs 58.3%, P<0.001) acquired in cases with IHBDAC. INHECA served as an independent protective factor for cases with IHCC. Even after matching, cases with IHBDCA still shared a higher incidence with CRD (P=0.010) and a worse prognosis, especially for cases who received surgery. ConclusionIHNECA was associated with less aggressive tumor biological features and worse prognosis. More in-depth research focusing on IHNECA with more detailed clinical and pathological data is required.

DNA concentrations in amniotic fluid according to gestational age and fetal sex: data from 2573 samples

PurposeIn some cases of prenatal genetic testing, an ample amount of fetal DNA is needed, to allow for parallel testing (conducting several genetic tests simultaneously). This study investigated the association between amniotic fluid DNA concentration and various factors. We aimed to define the required amount of amniotic fluid to be extracted in amniocentesis, to allow parallel testing throughout gestational weeks.MethodsDNA concentration was analyzed from amniocentesis samples taken during the years 2016–2022. Sex association was also analyzed in postnatal whole blood samples from a separate cohort. Theoretical minimum volume of amniotic fluid needed to ensure enough DNA for chromosomal microarray analysis and exome sequencing was calculated.ResultsWe focused our analysis on 2573 samples, which were taken during weeks 17–23 and 30–35. DNA concentrations increased from weeks 17 to 21, with relatively stable concentrations thereafter. Significantly higher DNA concentrations were seen in pregnancies of female fetuses. DNA concentrations in postnatal whole blood samples did not show this association. Across most weeks, the volume needed to extract 2 µg of DNA from 95% of the samples was about 34 ml.ConclusionDNA concentrations in amniotic fluid vary according to gestational age and are higher in pregnancies of female fetuses. This should be considered when determining the volume of fluid extracted and the timing of amniocentesis, with greater volumes needed in earlier stages of pregnancy.

Incidence and Risk Factors of Arytenoid Dislocation Following Endotracheal Intubation: A Systematic Review and Meta-Analysis.

Endotracheal intubation carries risks, including arytenoid dislocation (AD), a rare but severe complication. Due to small sample sizes, the incidence of AD varies considerably among studies. Proposed risk factors for AD include difficult intubation, prolonged intubation, certain surgeries, patient positioning, female sex, and BMI. This review aims to investigate the incidence of AD and explore the various predisposing risk factors. We retrieved relevant studies up to April 2024 from PubMed, Scopus, Web of Science, and the Cochrane Library. Using OpenMeta v5.26.14 software (Institute for Clinical Research and Health Policy Studies at Tufts Medical Center, Boston, USA), we pooled AD incidence rates from individual studies. Other outcomes, reported in fewer studies and thus not suitable for meta-analysis, were synthesized manually. Study selection yielded 16 eligible articles. A random-effects model analysis of nine studies found a significant AD incidence rate of 0.093% (confidence interval (CI): 0.045% to 0.14%), but the results were highly heterogeneous (I2 = 91%). Older age was associated with prolonged hoarseness, while younger age and female sex increased the risk of AD. Additionally, AD risk factors included taller stature, higher BMI, specific surgeries, esophageal instrumentation, prolonged procedure durations, head-neck movement, and inexperienced intubators. However, intubation with a stylet reduced the AD risk. AD post-endotracheal intubation is rare (incidence: 0.09%), with potential underdiagnosis in larger datasets. Many risk factors may contribute to the condition, but the small number of studies per risk factor limits the ability to draw robust conclusions. Subjective diagnoses and retrospective studies further restrict comprehensive understanding. Further research is needed to explore AD risk factors effectively.

Epidemiology of Hepatitis C over 28 years of monitoring Canadian blood donors: Insight into a low-risk undiagnosed population

BackgroundHepatitis C is a blood-borne infection with the hepatitis C virus (HCV) that can progress to cirrhosis and liver cancer. About 70% (50–80%) of infections become chronic and exhibit anti-HCV and HCV nucleic acid (NAT) positivity. Direct acting oral pan genotypic antiviral treatment became available in 2014 and was free for most Canadians in 2018. Clinical screening for HCV infection is risk-based. About 1% of Canadians have been infected with HCV, with 0.5% chronically infected (about 25% unaware) disproportionately impacting marginalized groups. Blood donors are in good health, are deferred for risks such as injection drug use and can provide insight into the low-risk undiagnosed population. Here we describe HCV epidemiology in first-time blood donors over 28 years of monitoring.MethodsAll first-time blood donors in all Canadian provinces except Quebec (1993 to 2021) were analyzed. All blood donations were tested for HCV antibodies (anti-HCV) and since late 1999 also HCV NAT. A case-control study was also included. All HCV positive donors (cases) since 2005 and HCV negative donors (1:4 ratio controls) matched for age, sex and location were invited to complete a risk factor interview. Separate logistic regression models for anti-HCV positivity and chronic HCV assessed the association between age cohort, sex, region and neighbourhood material deprivation and ethnocultural concentration. Case: control data were analysed by logistic regression.ResultsThere were 2,334,238 donors from 1993 to 2021 included. Prevalence for anti-HCV was 0.33% (0.30,0.37) in 1993 and 0.07% (0.05,0.09) in 2021 (p < 0.0001). In 2021 0.03% (0.01,0.04) had chronic HCV. Predictors for both anti-HCV positivity and chronic HCV were similar, for chronic HCV were male sex (OR 1.8, 1.6,2.1), birth between 1945 and 1975 (OR 7.1, 5.9,8.5), living in the western provinces (OR 1.4, 1.2,1.7) and living in material deprived (OR 2.7, 2.1,3.5) and more ethnocultural concentrated neighbourhoods (OR 1.8, 1.3,2.5). There were 318 (35.4%) of chronic HCV positive and 1272 (39.6%) of controls who participated in case control interviews. The strongest risks for acquisition were injection drug use (OR 96.9, 22.3,420.3) and birth in a high prevalence country (OR 24.5, 11.2,53.6).ConclusionsBlood donors have 16 times lower HCV prevalence then the general population. Donors largely mirror population trends and highlight the ongoing prevalence of untreated infections in groups without obvious risks for acquisition missed by risk-based patient screening.

Adherence to resistance training and hypocaloric diet among persons near retirement age — A secondary data analysis of three randomized controlled trials

ObjectivesAdherence to lifestyle interventions is crucial for the treatment of obesity. However, there is little research about adherence to lifestyle interventions in persons around retirement age. The objectives of this study are (1) to identify factors associated with the adherence to resistance training and a hypocaloric diet and (2) to describe the association between adherence and changes in body composition outcome parameters. DesignThis secondary data analysis included three randomized controlled trials. Setting & participantsThe inclusion criteria of the participants were an age of 55–75 years, a BMI ≥ 25 kg/m2 and receiving both a hypocaloric diet and resistance training. All participants were residing in the community. MeasurementsAdherence to hypocaloric diet was measured through the mean dietary intake on the basis of a 3-day dietary record. If the participant consumed at least 600 kcal less than the individual caloric requirements, they were considered adherent. Adherence to resistance training was achieved if ≥67% of the recommended training sessions were attended over the course of the study periods. Results232 participants were included, 47.0% female, mean age 64.0 (±5.5) years. 80.2% adhered to resistance training and 51.3% adhered to a hypocaloric diet. Older age (Beta 0.41; 95% CI 0.05, 0.78; p = 0.028) and male sex (Beta 7.7; 95% CI 3.6, 11; p < 0.001) were associated with higher resistance training adherence. A higher BMI at baseline (Beta 6.4; 95% CI 3.6, 9.2; p < 0.001) and male sex (Beta 65; 95% CI 41, 88; p < 0.001) were associated with higher adherence to hypocaloric diet. ConclusionWe identified several associated factors (sex, age and BMI at baseline) that should be considered to promote adherence in future lifestyle intervention studies in persons around retirement age. We recommend including behavior change techniques in lifestyle interventions and consider sex-specific interventions to improve the adherence of women.

Investigating the utility of the AQ-10 in children and adolescents assessed in an outpatient ARFID clinic.

The high co-occurrence of autism and eating disorders is well established, including for those with Avoidant Restrictive Food Intake Disorder (ARFID). It is therefore important to consider autism and identify possible autism when people present to eating disorder services to ascertain whether further assessment is indicated, to support clinical formulation and to make appropriate adaptations during interventions. This paper explores the utility of a validated autism screening measure, the AQ-10, in a population of children and adolescents who presented to an outpatient eating disorders clinic for an assessment of possible ARFID. Over 19 months, 335 young people were assessed and 246 families with children aged between 4 and 17 years completed one of three versions of the AQ-10 (Child, Adolescent, and Adult), as part of a battery of routinely administered pre-assessment questionnaires. Results indicated that 80.2% (n = 69) of those with an existing autism diagnosis scored above clinical threshold of ≥6 (M = 7.2, SD = 1.9), 43.9% (n = 43) of those queried to be autistic scored above clinical threshold (M = 5.2, SD = 2.5), and 6.5% (n = 4) of non-autistic individuals scored above clinical threshold (M = 2.8, SD = 1.8). Additionally, the AQ-10 satisfactorily discriminated between those with a known autism diagnosis and those who are not autistic across all age groups and sex. We conclude that the AQ-10, alongside a comprehensive clinical assessment and clinical judgment, is a useful screening tool that can support clinicians to identify appropriate onward referrals for autism assessments, aid clinical formulation, and consider appropriate adaptations and reasonable adjustments during ARFID interventions.

Age and sex-specific risk in fractures with Down syndrome in a retrospective case-control study from Germany.

The increasing life expectancy of individuals with Down syndrome has led to a growing awareness of mid- and late-life conditions. Based on the Disease Analyser database (IQVIA), this retrospective cohort study compared adults ≥18years of age with Down syndrome (ICD-10: Q90) in general practices in Germany with a propensity score-matched cohort without Down syndrome. The outcome was the first diagnosis of a fracture within 5years of the index date. The cumulative incidence of fractures over a 5-year period was presented using Kaplan-Meier curves. Univariable Cox regression analyses by age group and sex were performed to assess the association between Down syndrome and fractures. A total of 2547 individuals with Down syndrome and 12735 individuals without Down syndrome were included in the study. A significantly higher cumulative fracture incidence within 5years was observed in the age group 51-60years (9.3% Down syndrome vs. 4.8% without Down syndrome, P=0.003) as well as in the age group >60years (20.3% Down syndrome vs. 8.6% without Down syndrome, P<0.001) compared with the cohort without Down syndrome. Regression analysis showed a significant association between Down syndrome and fracture risk in women with Down syndrome aged 51-60years (hazard ratio [HR]=1.60; 95% confidence interval [CI]: 1.13-2.26), and in those aged 51-60years (HR=2.08; 95% CI: 1.27-3.41) and >60years (HR=2.98; 95% CI: 1.87-4.73)), but not in men. When comparing fractures in individuals with and without Down syndrome, shoulder and arm fractures were most common in the Down syndrome cohort. The results of our study indicate a positive association between individuals with Down syndrome and subsequent fractures in women and those aged >50years. Prevention of falls appears to be particularly important in these populations. However, future studies should clarify the extent to which socio-economic factors, such as housing, play a role in this context.

Dietary factors may be associated with measures of ultrasound-derived skeletal muscle echo intensity.

Skeletal muscle echo intensity (EI) is affected by ageing and physical activity; however, the effects of nutrition are less understood. The aim of this study was to explore whether habitual nutrient intake may be associated with ultrasound-derived EI. Partial least squares regression (PLSR) models were trained on an initial sample (n=100, M=45; F=55; 38±15 years) to predict EI of two quadriceps muscles from 19 variables, using the "jack-knife" function within the "pls" package (RStudio), which was then tested in an additional dataset (n=30, M=13; F=17; 38±16 years). EI was determined using B-mode ultrasonography of the rectus femoris (RF) and vastus lateralis (VL) and nutritional intake determined via 3-day weighed food diaries. Mean daily intake of specific nutrients were included as predictor variables with age, sex, and self-reported physical activity. PLSR training model 1 explained ∼52% and model 2 ∼46% of the variance in RF and VL EI, respectively. Model 1 also explained ∼35% and model 2 ∼30% of the variance in RF and VL EI in the additional testing dataset. Age and biological sex were associated with EI in both models (P<0.025). Dietary protein (RF: β = -7.617, VL: β = -7.480), and selenium (RF: β = -7.144, VL: β = -4.775) were associated with EI in both muscles (P<0.05), whereas fibre intake (RF: β = -5.215) was associated with RF EI only and omega-3 fatty acids (n-3/ω-3 FAs, RF: β = 3.145) with VL EI only (P<0.05). Therefore, absolute protein, selenium, fibre, and n-3 FAs may be associated with skeletal muscle EI, although further mechanistic work is required before claiming causal inference.

Perinatal Factors Associated with Successful Pharmacologic Closure of the Patent Ductus Arteriosus in Premature Infants.

The patent ductus arteriosus (PDA) is associated with significant morbidity and mortality in preterm infants. While pharmacologic closure of the PDA is common and effective, it can be difficult to identify which patients will respond. As such, the objective of this study was to identify factors associated with successful pharmacologic closure of the PDA. We hypothesized that clinical factors such as gestational age, birth weight, and hypertensive disorders of pregnancy would be associated with successful closure. We performed a retrospective cohort study of preterm infants who received pharmacologic treatment for a PDA at two large neonatal intensive care units in Boston, MA between January 2016 and December 2021. Infants were excluded if they received prophylactic indomethacin, had early termination of therapy, did not have an echocardiogram prior to therapy, or had congenital heart disease. The primary outcome was closure after initial course. Relevant perinatal data were collected on enrolled infants. Of the 215 enrolled infants, 131 (61%) had successful closure. Older gestational age (OR, 1.23; 95% CI,1.03-1.47), male sex (OR, 2.17; 95% CI,1.18-3.99), and maternal preeclampsia (OR, 2.75; 95% CI,1.07-7.02) were associated with successful closure. Infants who received postnatal steroids (OR, 0.49; 95% CI,0.25-0.96) were less likely to have had successful closure. In this study, we identified previously established associations of gestational age and male sex with successful pharmacologic closure. However, the associations with maternal preeclampsia and postnatal steroids are novel. While further investigation is warranted, these associations can help inform decision-making around management of the PDA.

Psychometric analysis and adaptation of the generalized anxiety questionnaire (GAD-7) to the Collao Quechua language in Peru.

To adapt the 7-item Generalized Anxiety Questionnaire (GAD-7) from English to the cultural and linguistic context of Quechua Collao and to analyze its psychometric properties in Puno, Peru. The GAD-7 in its original version was translated into the Collao Quechua variety and its psychometric properties were analyzed. The participants were bilingual (Spanish and Quechua), over 18 years of age and of both sexes. The exploratory factor analysis (EFA) was evaluated using parallel analysis, confirmatory factor analysis (CFA) and goodness-of-fit indices; reliability was also analyzed using McDonald's classic alpha and Omega. Judges and focus group participants conducted the cultural and linguistic adaptation of the GAD-7 to Quechua Collao; the EFA reported the presence of a single factor (KMO=0.88, p=0.01); while the CFA confirmed adequate adjustments in the unifactorial model (CFI=0.994; TLI=0.991; SRMR=0.027; RMSEA=0.092), good reliability (α=0.896; ω=0.894) and was also invariant across age groups, sex, marital status and educational level. The questionnaire showed validity for a unidimensional model of the GAD-7 adapted to the Collao Quechua, as well as optimal reliability and invariance by the evaluated groups. Its use could benefit anxiety research and care.

Evaluation of some hormones in patients with major β-Thalassemia in the Nineveh Governorate - Iraq

Thalassemia is one of the most important genetic haemolytic diseases that cause the breakdown of red blood cells (RBCs) in patients with β-Thalassemia major. The body does not produce enough haemoglobin, which is an important part of RBCs. When there is not enough haemoglobin, RBCs do not function properly in the body, so the condition continues for short periods of time. The current studies aimed to determine the extent of the impact of β-Thalassemia major on some hormonal variables in the serum of 80 patients (40 males and 40 females) aged between (1-15) years, in addition to 20 healthy children of the same age range and of both sexes, who were considered as a control group. The results of this study showed a significant increase in the concentration of erythropoietin (EPO) by 187% in the serum of patients with β-Thalassemia major compared to healthy of both sexes, with an increase of 188 in males and 183% in females. The highest significant increase was in the age group of (11-15) years in males and females compared to healthy control. The results also showed a significant decrease in the concentration of hepcidin and growth hormones in the serum of patients with a decrease of 55 and 56% respectively compared to healthy individuals of both sexes, with a highest significant decrease of 56 and 59% in males, and 55 and 52% in females respectively. The highest significant decrease was in the age group of (11-15) years for both hormones in males and females compared to healthy control based on age groups and sex.

Incidence and Survival Outcomes of Gastrointestinal Stromal Tumors

The incidence of gastrointestinal stromal tumors (GISTs) increased after the implementation of GIST-specific histology coding in 2001, but updated data on trends and survival are lacking. To examine the evolving epidemiology of GISTs in major organ sites. This descriptive, population-based cohort study used nationally representative data from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) Program, including the SEER-22 and SEER-17 registries. Data were from evaluated patients aged 20 years or older with GISTs diagnosed between January 1, 2000, and December 31, 2019. Analyses were last updated on October 29, 2023. Organ site-specific trends in age-standardized incidence rates and annual percent changes (APCs) in rates were estimated by race and ethnicity and, when possible, by sex, age, and primary indicator. Multivariable Cox proportional hazards regression models were used to examine racial and ethnic differences in overall and GIST-specific survival by site. The SEER-22 and SEER-17 datasets contained 23 001 and 12 109 case patients with GISTs, respectively. Patients in the SEER-22 registry had a mean (SD) age of 64 (13) years and 51.3% were men. With regard to race and ethnicity, 9.7% of patients were Asian or Pacific Islander, 12.3% were Hispanic, 19.6% were non-Hispanic Black, and 57.7% were non-Hispanic White. Overall incidence rates of GISTs in the SEER-22 cohort increased substantially over time for all organ sites but the colon (APCs: esophagus, 7.3% [95% CI, 4.4% to 10.2%]; gastric, 5.1% [95% CI, 4.2% to 6.1%]; small intestine, 2.7% [95% CI, 1.8% to 3.7%]; colon, -0.2% [95% CI, -1.3% to 0.9%]; and rectum, 1.9% [95% CI, 0.1% to 3.8%]). There were similar increasing trends by age groups (<50 vs ≥50 years), sex, race and ethnicity, and primary indicator for gastric and small intestine GISTs. Increases were mainly restricted to localized stage disease. Patients in the SEER-17 cohort had a mean (SD) age of 64 (14) years and 51.9% were men. With regard to race and ethnicity, 13.3% of patients were Asian or Pacific Islander, 11.6% were Hispanic, 17.8% were non-Hispanic Black, and 56.6% were non-Hispanic White. Non-Hispanic Black individuals had higher overall mortality for esophageal (adjusted hazard ratio [HR], 6.4 [95% CI, 2.0 to 20.3]) and gastric (adjusted HR, 1.4 [95% CI, 1.2 to 1.5]) GISTs compared with non-Hispanic White individuals. Asian or Pacific Islander individuals also had higher overall mortality for esophageal GISTs (adjusted HR, 5.6 [95% CI, 1.5 to 20.2]). Results were similar for GIST-specific survival. In this cohort study using SEER data, the incidence of GISTs in major organ sites increased in the last 2 decades among several population groups. These findings suggest that additional studies are warranted to identify risk factors, because histologic reclassification and higher availability of endoscopy and imaging do not fully explain these unfavorable incidence trends. Prevention efforts are needed to reduce the substantial survival disparities among racial and ethnic minoritized populations.

Smoking Habit and Coffee Consumption with Gastritis Incidence Rate at Productive Ages

Gastritis is a disease caused by an inflammation of the mucous and submucosal lining of the stomach. Several studies show that there is an influence of smoking habit and coffee consumption on gastritis incidence rate. The study was to determine the correlation between smoking habit and coffee consumption toward gastritis at productive ages. The research is an analytical observational study with a cross-sectional design conducted in Makale Health Center, South Sulawesi, in February 2020. Required data was gathered by conducting guided interviews using a questionnaire that includes age range, sex, and education level. Brinkman Index was used to measure smoking habits, coffee consumption, and gastritis questionnaire. Data was analyzed using a chi-square test with a significance level of p=0.05. From a total of 115 respondents, there are 69.6% included in the age range of 26–35 years old, 58.3% have mild smoking habits, 56.5% have severe coffee consumption, and 85.2% are suffering from gastritis. There is a relation between smoking habit (p=0.029) and coffee consumption (p=0.003) with gastritis (p&lt;0.05). The conclusion is that there is a relationship between smoking habits, coffee consumption, and gastritis incidence.

Polyp detection with colonoscopy assisted by the GI Genius artificial intelligence endoscopy module compared with standard colonoscopy in routine colonoscopy practice (COLO-DETECT): a multicentre, open-label, parallel-arm, pragmatic randomised controlled trial

Increased polyp detection during colonoscopy is associated with decreased post-colonoscopy colorectal cancer incidence and mortality. The COLO-DETECT trial aimed to assess the clinical effectiveness of the GI Genius intelligent endoscopy module for polyp detection, comparing colonoscopy assisted by GI Genius (computer-aided detection [CADe]-assisted colonoscopy) with standard colonoscopy in routine practice. We did a multicentre, open-label, parallel-arm, pragmatic randomised controlled trial in 12 National Health Service (NHS) hospitals (ten NHS Trusts) in England, among adults (aged ≥18 years) undergoing planned colonoscopy for gastrointestinal symptoms or for surveillance due to personal or family history (ie, symptomatic indications), or colorectal cancer screening. Randomisation (1:1) to CADe-assisted colonoscopy or standard colonoscopy was done with a web-based dynamic adaptive algorithm, immediately before colonoscopy, with stratification by age group, sex, colonoscopy indication (screening or symptomatic), and NHS Trust. Recruiting staff, participants, and colonoscopists were unmasked to trial allocation; histopathologists, co-chief investigators, and trial statisticians were masked. CADe-assisted colonoscopy consisted of standard colonoscopy plus the GI Genius module active for at least the entire inspection phase of colonoscope withdrawal. The primary outcome was mean adenomas per procedure (total number of adenomas detected divided by total number of procedures); the key secondary outcome was adenoma detection rate (proportion of colonoscopies with at least one adenoma). Analysis was by intention to treat (ITT), with outcomes compared between groups by mixed-effects regression modelling, in which effect estimates were adjusted for randomisation stratification variables. Data were imputed for outcome measures with more than 5% missing values. All participants who underwent colonoscopy were assessed for safety. The trial is registered on ISRCTN (ISRCTN10451355) and ClinicalTrials.gov (NCT04723758), and is complete. Between March 29, 2021, and April 6, 2023, 2032 participants (1132 [55·7%] male, 900 [44·3%] female; mean age 62·4 years [SD 10·8]) were recruited and randomly assigned: 1015 to CADe-assisted colonoscopy and 1017 to standard colonoscopy. 1231 (60·6%) participants were undergoing screening and 801 (39·4%) had symptomatic indications. Mean adenomas per procedure was 1·56 (SD 2·82; n=1001 participants with available data) in the CADe-assisted colonoscopy group versus 1·21 (1·91; n=1009) in the standard colonoscopy group, representing an adjusted mean difference of 0·36 (95% CI 0·14-0·57; adjusted incidence rate ratio 1·30 [95% CI 1·15-1·47], p<0·0001). Adenomas were detected in 555 (56·6%) of 980 participants in the CADe-assisted colonoscopy group versus 477 (48·4%) of 986 in the standard colonoscopy group, representing a proportion difference of 8·3% (95% CI 3·9-12·7; adjusted odds ratio 1·47 [95% CI 1·21-1·78], p<0·0001). Numbers of adverse events were similar between the CADe-assisted colonoscopy and standard colonoscopy groups (adverse events: 25 vs 19; serious adverse events: four vs six), and no adverse events in the CADe-assisted colonoscopy group were deemed to be related to GI Genius use on independent review. Results of the COLO-DETECT trial support the use of GI Genius to increase detection of premalignant colorectal polyps in routine colonoscopy practice. Medtronic.

Macular neurodegenerative and vascular changes on OCTA in sickle cell disease are not related to its ocular and systemic complications.

To evaluate macular abnormalities in sickle cell disease (SCD) with OCT-Angiography (OCTA) and to determine associations with sickle cell retinopathy (SCR) and clinical and laboratory characteristics. Complete ophthalmic examination was performed in consecutive SCD patients (HbSS, HbSC, HbSβ0 or HbSβ+ genotype), including fundoscopy and macular SD-OCT/OCTA scans. SCR stage was based on fundoscopic examination (without fluorescein angiography) instead of the Goldberg classification, since fluorescein angiography was only used in case of tentative diagnosis. Medical/ophthalmological history and hematologic characteristics were retrieved from medical records. 249 eyes of 137 patients were analyzed. The mean age was 33.3 ± 12.4 years (range 15-70). Non-proliferative SCR was present in 57 eyes (22.9%) and proliferative SCR in 36 eyes (14.5%). Macular thinning was present in 100 eyes (40.2%) and was associated with lower foveal vessel density (VD) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) and with enlargement of the foveal avascular zone (FAZ) area, perimeter and acircularity index (AI). Age and female sex were associated with lower (para)foveal VD in the SCP and DCP. No associations were found between SCR presence/severity and macular thinning or VD. Macular abnormalities were common, but did not result in visual impairment. No relation with SCR presence/severity was found. While OCTA-imaging is suitable for detecting maculopathy, it appears to have no diagnostic value in identifying patients at risk for SCR.

VV-ECMO in critical COVID-19 obese patients: a cohort study

BackgroundObesity causes significant difficulties in successful extracorporeal membrane oxygenation (ECMO) support and may interfere with patient outcomes. During the COVID-19 pandemic, we experienced an increased number of obese patients supported with ECMO in our intensive care unit due to severe illness in this population.MethodsWe designed a single-center retrospective study to identify prognostic factors for 180-day survival in obese critical COVID-19 patients receiving venovenous ECMO (VV-ECMO). We included adult critical COVID-19 patients on VV-ECMO, who were obese and overweight (according to the World Health Organization) and admitted to a tertiary hospital’s intensive care unit from April 1, 2020, to May 31, 2022. Univariate logistic regression analysis was performed to assess differences in 180-day mortality.ResultsForty-one patients were included. The median age was 55 (IQR 45–60) years, and 70.7% of the patients were male. The median body mass index (BMI) was 36 (IQR 31–42.5) kg/m2; 39% of patients had a BMI ≥ 40 kg/m2. The participants had 3 (IQR 1.5–4) days of mechanical ventilation prior to ECMO, and 63.4% were weaned from VV-ECMO support after a median of 19 (IQR 10–34) days. The median ICU length of stay was 31.9 (IQR 17.5–44.5) days. The duration of mechanical ventilation was 30 (IQR 19–49.5) days. The 180-day mortality rate was 41.5%. Univariate logistic regression analysis revealed that a higher BMI was associated with greater 180-day survival (OR 1.157 [1.038–1.291], p = 0.009). Younger age, female sex, less invasive ventilation time before ECMO, and fewer complications at the time of ECMO cannulation were associated with greater 180-day survival [OR 0.858 (0.774–0.953), p 0.004; OR 0.074 (0.008–0.650), p 0.019; OR 0.612 (0.401–0.933), p 0.022; OR 0.13 (0.03–0.740), p 0.022), respectively].ConclusionIn this retrospective cohort of critical COVID-19 obese adult patients supported by VV-ECMO, a higher BMI, younger age, and female sex were associated with greater 180-day survival. A shorter invasive ventilation time before ECMO and fewer complications at ECMO cannulation were also associated with increased survival.

Retrospective cohort study identifying pulmonary complications in a cohort of patients with systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with multi organ involvement. One of the most common manifestations is pulmonary disease with a reported prevalence between 5%-90%. Given this wide range of prevalence, there is a need to more closely define types of pulmonary disease in SLE and associated risk factors. We sought to characterize the presentation of pulmonary manifestations in an established SLE cohort using electronic health record data. All patients were >18 years of age and had confirmed SLE by a rheumatologist using SLICC or 2019 ACR/EULAR classification criteria. 220 patients with imaging were included in this study; average age was 42.5 years, 86.7% identified as female, 60.5% identified as white, 37.3% as Black, and 1.82% as Asian. Generalized estimating equations were utilized to analyze the data, accounting for its repeated measured nature. We found an association between smoking (present/prior smoker) and radiologist reported disease on computerized tomography (CT) scan, as well as an association between smoking (present/prior smoker), older age, and male sex with having pulmonary disease identified on chest X-ray. The most common findings on CT and X-ray were increased lung density (24%, 12%) and atelectasis (18%, 10%). The most common disease found on CT was pleural effusion (24%) and mediastinal/axillary lymphadenopathy (16%). While our study is limited by the retrospective nature, our results show that certain factors, namely smoking, older age, or male sex should prompt clinicians to have a higher suspicion for lung disease in SLE patients.
