Comparison of Quantitative Radiomorphometric Predictors of Healthy and MRONJ-Affected Bone Using Panoramic Radiography and Cone-Beam CT.

OBJECTIVES: To determine the most distinctive quantitative radiomorphometric parameter(s) for the detection of MRONJ-affected bone changes in panoramic radiography (PR) and cone-beam computed tomography (CBCT). METHODS: PR and sagittal CBCT slices of 24 MRONJ patients and 22 healthy controls were used for the measurements of mandibular cortical thickness (MCT), fractal dimension (FD), lacunarity, mean gray value (MGV), bone area fraction (BA/TA), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), trabecular number (Tb.N). MCT was measured in the mental foramen region. While FD and lacunarity were measured on mandibular trabecular and cortical regions of interest (ROIs), the remaining parameters were measured on trabecular ROIs. The independent samples t-test was used to compare the measurements between MRONJ and control group for both imaging modalities (p = 0.05). RESULTS: MCT was the only parameter that differentiated MRONJ-affected bone in both PR and CBCT (p < 0.05). None of the remaining parameters revealed any difference for MRONJ-affected bone in CBCT (p > 0.05). FD, lacunarity, MGV, BA/TA, and Tb.Sp could distinguish MRONJ-affected trabecular bone in PR (p < 0.05). The correspondent ROI for both imaging methods that was reliable for detecting MRONJ-affected bone was the trabecular bone distal to the mental foramen above the inferior alveolar canal (ROI-3). CONCLUSIONS: MCT is a reliable parameter for the discrimination of MRONJ-affected bone in both PR and CBCT images. PR may be used to detect MRONJ-affected trabecular bone using FD, lacunarity, MGV, BA/TA, and Tb.Sp measurements as well.

Can artificial intelligence detect type 2 diabetes in women by evaluating the pectoral muscle on tomosynthesis: diagnostic study.

OBJECTIVES: This retrospective single-center analysis aimed to evaluate whether artificial intelligence can detect type 2 diabetes mellitus by evaluating the pectoral muscle on digital breast tomosynthesis (DBT). MATERIAL METHOD: An analysis of 11,594 DBT images of 287 consecutive female patients (mean age 60, range 40-77 years) was conducted using convolutional neural networks (EfficientNetB5). The inclusion criterion was left-sided screening images with unsuspicious interpretation who also had a current glycosylated hemoglobin A1c (HBA1c) % value. The exclusion criteria were inadequate imaging, history of breast cancer, and/or diabetes mellitus. HbA1c values between 5.6 and 6.4% were categorized as prediabetic, and those with values ≥ 6.5% were categorized as diabetic. A recorded HbA1c ≤ 5.5% served as the control group. Each group was divided into 3 subgroups according to age. Images were subjected to pattern analysis parameters then cropped and resized in a format to contain only pectoral muscle. The dataset was split into 85% for training and 15% for testing the model's performance. The accuracy rate and F1-score were selected as performance indicators. RESULTS: The training process was concluded in the 15th epoch, each comprising 1000 steps, with an accuracy rate of 92% and a loss of only 0.22. The average specificity and sensitivity for all 3 groups were 95%. The F1-score was 0.95. AUC-ROC was 0.995. PPV was 94%, and NPV was 98%. CONCLUSION: Our study presented a pioneering approach, applying deep learning for the detection of diabetes mellitus status in women using pectoral muscle images and was found to function with an accuracy rate of 92%. CRITICAL RELEVANCE STATEMENT: AI can differentiate pathological changes within pectoral muscle tissue by assessing radiological images and maybe a potential diagnostic tool for detecting diabetes mellitus and other diseases that affect muscle tissues. KEY POINTS: • AI may have an opportunistic use as a screening exam for diabetes during digital breast tomosynthesis. • This technique allows for early and non-invasive detection of diabetes mellitus by AI. • AI may have broad applications in detecting pathological changes within muscle tissue.

Understanding clinical outcomes and factors influencing mortality in intensive care unit patients with COVID-19-associated candidemia.

BACKGROUND: During the COVID pandemic, research has shown an increase in candidemia cases following severe COVID infection and the identification of risk factors associated with candidemia. However, there is a lack of studies that specifically explore clinical outcomes and mortality rates related to candidemia after COVID infection. OBJECTIVES: The aim of this international study was to evaluate the clinical outcomes and identify factors influencing mortality in patients who developed candidemia during their COVID infection. PATIENTS/METHODS: This study included adult patients (18 years of age or older) admitted to the intensive care unit (ICU) and diagnosed with COVID-associated candidemia (CAC). The research was conducted through ID-IRI network and in collaboration with 34 medical centres across 18 countries retrospectively, spanning from the beginning of the COVID pandemic until December 2021. RESULTS: A total of 293 patients diagnosed with CAC were included. The median age of the patients was 67, and 63% of them were male. The most common Candida species detected was C. albicans. The crude 30-day mortality rate was recorded at 62.4%. The logistic regression analysis identified several factors significantly impacting mortality, including age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.07, p < .0005), SOFA score (OR 1.307, 95% CI 1.17-1.45, p < .0005), invasive mechanical ventilation (OR 7.95, 95% CI 1.44-43.83, p < .017) and duration of mechanical ventilation (OR 0.98, 95% CI 0.96-0.99, p < .020). CONCLUSIONS: By recognising these prognostic factors, medical professionals can customise their treatment approaches to offer more targeted care, leading to improved patient outcomes and higher survival rates for individuals with COVID-associated candidemia.

Registry-Based Retrospective Cohort Study of Mortality among Adults Admitted to Intensive Care Units in Istanbul with Hospital Acquired Pseudomonas aeruginosa Bloodstream-Infection between 2014-2021.

BACKGROUND: Managing Pseudomonas aeruginosa bloodstream infections (BSIs) is challenging due to increasing antimicrobial resistance, limited therapeutic options, and high mortality rates. In this study, we aimed to identify 30-day mortality risk factors and assess infectious diseases consultants' preferences for combination or monotherapy. METHODS: The study was conducted in four hospitals in Istanbul, Turkey, involving 140 adult ICU beds and 336,780 ICU-bed-days between 1 January 2014, and 31 December 2021. A total of 157 patients were included in the study. Cox proportional hazard regression was performed to assess the factors on 30-day mortality. RESULTS: The 30-day mortality rate was 44.6% (70/157). Higher Charlson Comorbidity Index (CCI) score, severe sepsis, primary bloodstream infection, being in COVID-19 pandemic period, and infection caused by MDR strain were associated with higher hazard of 30-day mortality. Combination therapy was more commonly used in patients with BSIs with MDR or DTR (difficult-to-treat) strains but did not significantly improve the hazard of 30-day mortality. CONCLUSIONS: Targeted interventions and vigilant management strategies are crucial for patients with defined risk factors. While infectious disease consultants tended to favor combination therapy, particularly for drug-resistant strains, our analysis revealed no significant impact on 30-day mortality hazard. The increased incidence of P. aeruginosa BSIs during the pandemic emphasizes the need for infection control measures and appropriate antibiotic prescribing practices.

A Retrospective Analysis of 83 Patients with Testicular Mass Who Underwent Testis-Sparing Surgery: The Eurasian Uro-oncology Association Multicenter Study.

INTRODUCTION: Herein, we analyzed the histopathological, oncological and functional outcomes of testis-sparing surgery (TSS) in patients with distinct risk for testicular cancer. METHODS: This is a multicenter retrospective study on consecutive patients who underwent TSS. Patients were categorized in high- or low-risk testicular germ cell tumor (TGCT) according to the presence/absence of features compatible with testicular dysgenesis syndrome. Histology was categorized per size and risk groups. RESULTS: TSS was performed in 83 patients (86 tumors) of them, 27 in the high-risk group. Fifty-nine patients had a non-tumoral contralateral testis present. Sixty masses and 26 masses were benign and TGCTs, respectively. No statistical differences were observed in mean age (30.9 ± 10.32 years), pathological tumor size (14.67 ± 6.7 mm) between risk groups or between benign and malignant tumors (p = 0.608). When categorized per risk groups, 22 (73.3%) and 4 (7.1%) of the TSS specimens were malignant in the high- and low-risk patient groups, respectively. Univariate analysis showed that the only independent variable significantly related to malignant outcome was previous history of TGCT. During a mean follow-up of 25.5 ± 22.7 months, no patient developed systemic disease. Local recurrence was detected in 5 patients and received radical orchiectomy. Postoperative testosterone levels remained normal in 88% of those patients with normal preoperative level. No erectile dysfunction was reported in patients with benign lesions. CONCLUSION: TSS is a safe and feasible approach with adequate cancer control, and preservation of sexual function is possible in 2/3 of patients harboring malignancy. Incidence of TGCT varies extremely between patients at high and low risk for TGCT requiring a careful consideration and counseling.

Can the Second and Fourth Finger (2D: 4D) Ratio Guide Physicians in Choosing Internal Medicine or Surgical Branch? / ¿Puede la proporción del Segundo y Cuarto Dedo (2D: 4D) Guiar a los Médicos en la Elección de Medicina Interna o Rama Quirúrgica?

SUMMARY: This study investigates the relationship between the second and fourth finger ratio (2D:4D), physicians' propensity to choose an internal or surgical branch, and sex differences. On a voluntary basis, 177 physicians working in Elazig, 122 men and 55 women were enrolled in the study. Their hands were measured for 2D and 4D lengths, and the 2D:4D ratio was computed. In female doctors, the left hand's 2D:4D ratio is 1.01, compared to the right hand's 1.00. Male doctors' right 2D:4D ratio is 0.99, while their left 2D:4D ratio is 1.00. Male physicians' 2D:4D ratios were different from those of men in the general population, whereas female physicians' 2D:4D ratios were comparable to those of women in the general population. As a result, this study was the first to examine the relationship between the ratio of the second and fourth fingers (2D:4D), physicians' tendency to choose an internal medicine or surgical branch, and sex differences. While the 2D:4D ratio was higher than 0.98 in all physicians, it was low in women who disliked their profession and branch. Since there aren't many studies on this subject, data from in-depth studies that will be conducted in the future will help physicians who choose internal medicine and surgery make more informed decisions.

Este estudio investiga la relación entre la proporción de los dedos segundo y cuarto (2D:4D), la propensión de los médicos a elegir una rama interna o quirúrgica y las diferencias de género. De forma voluntaria, se inscribieron en el estudio 177 médicos que trabajaban en Elazig, 122 hombres y 55 mujeres. Sus manos se midieron en longitudes 2D y 4D, y se calculó la relación 2D:4D. En las médicos mujeres, la relación 2D:4D de la mano izquierda es 1,01, en comparación con 1,00 de la mano derecha. La relación 2D:4D derecha de los médicos hombres fue 0,99, mientras que la relación 2D:4D izquierda fye 1,00. Las proporciones 2D:4D de los médicos hombres fueron diferentes de las de los hombres en la población general, mientras que las proporciones 2D:4D de las mujeres médicas fueron comparables a las de las mujeres en la población general. Como resultado, este estudio fue el primero en examinar la relación entre la proporción del segundo y cuarto dedo (2D:4D), la tendencia de los médicos a elegir una rama de medicina interna o quirúrgica y las diferencias de sexo. Mientras que la relación 2D:4D fue superior a 0,98 en todos los médicos, fue baja en las mujeres que no les gustaba su profesión y rama. Dado que no hay muchos estudios sobre este tema, los datos de estudios en profundidad que se realizarán en el futuro ayudarán a los médicos que eligen medicina interna y cirugía a tomar decisiones más informadas.

The Effects of Chronic Asprosin Administration on Sense of Smell and Sexual Behavior in Female Rats.

INTRODUCTION: Asprosin is an adipokine released from white adipose tissue during fasting and acts through the olfactory receptor. It is known that adipokines play roles in reproductive physiology in mammals. However, there are very few studies conducted on role of asprosin in reproductive functions. There are no studies on its relationship with sexual motivation. It was shown in the literature that administration of asprosin to male mice improves olfaction. It is also known that there is a strong correlation between smell and sexual desire. In view of this, it was hypothesized that chronic administration of asprosin would improve olfactory performance and increase sexual incentive motivation in female rats for male partners. METHODS: This hypothesis was tested by applying the hidden cookie test, sexual incentive test, active research test, and sexual behavior test. The changes in serum hormone levels in female rats that chronically received asprosin were also measured and compared. RESULTS: Chronic asprosin exposure increased olfactory performance, male preference ratio, male investigation preference ratio, activity index, and anogenital investigation behavior. Also, serum oxytocin and estradiol levels increased following chronic administration of asprosin in female rats. CONCLUSION: These data suggest that chronic administration of asprosin can result in increased sexual incentive motivation for opposite sex in female rats over increased olfactory performance and changes in reproductive hormones.

Eosinophilic lymph node abscesses following a COVID-19 vaccination: A case report.

In this paper, we reported a 37-year-old man who developed several lymphadenopathies after using the second dose of Pfizer-BioNtech vaccination against SARS-CoV-2. The excisional lymph node biopsy showed eosinophil-rich inflammation with micro-abscesses. Although eosinophilic dermatosis and eosinophilic myocarditis have been described previously following COVID-19 vaccinations, eosinophilic lymph node abscess was not reported in the literature. In our case, all lesions were completely recovered with steroid treatment. The patient has been doing well and no recurrence has been observed for six months.

Risk factors for carbapenem-resistant Klebsiella pneumoniae infections in Intensive Care Units: a multicentre case-control study with a competing-risks analysis.

Aim: This study investigated the risk factors for the development of carbapenem-resistant Klebsiella pneumoniae (CRKP) infections in adult patients in Intensive Care Units (ICUs). Methods: A multicentre case-control study was conducted in ICUs in three tertiary hospitals in Turkey. The cases were patients culture-confirmed CRKP and a condition associated with healthcare-associated infections. Two controls were randomly selected for each case from among all other patients with an ICU stay at least as long as that of the corresponding case-patient. A proportional semiparametric subdistribution hazards regression model was used to assess risk factors for CRKP infection. ICU discharge and non-CRKP-related deaths were treated as competing risks. Results: A total of 120 patients, 44 cases and 76 controls were included in the analysis. Of the controls, 32 were discharged from the ICU and 44 died without acquiring CRKP infection. Endotracheal intubation (hazard ratio [HR]: 1.96, 95% confidence interval [CI]: 1.00-3.868) and type 2 diabetes mellitus (HR: 1.57, 95% CI: 0.888-2.806) were associated with an increased risk of CRKP infection, whereas carbapenem exposure (HR: 0.47, 95% CI: 0.190-1.1175) and the presence of a nasogastric tube (HR: 0.49, 95% CI: 0.277-0.884) were associated with a decreased risk of CRKP infection. Conclusions: Enteral nutrition support via a nasogastric tube may be associated with a reduced risk of CRKP-resistant infections in ICU patients. This hypothesis should be tested with a well-designed study.

Multiple Endoclip Retraction Technique (MERT) in Laparoscopic Burch.

Background and Objectives: The multiple endoclip retraction technique (MERT) was developed based on our experience with suturing renal parenchyma in laparoscopic partial nephrectomy. In this study we prospectively evaluated the one-year results of cases treated by transperitoneal laparoscopic Burch with the MERT. Methods: The patients were evaluated with stress test, one-hour pad test, and were requested to complete the International Continence Society Incontinence Questionnaire short form (ICIQ-SF) in the postoperative period. The follow-up periods were postoperative 3, 6, and 12 months. Results: The primary outcome of this study was surgical success, defined as being cured of stress urinary incontinence (SUI) (no symptoms), experiencing improved symptoms of SUI in ICIQ-SF and negative stress test, and less than 2g urine leakage in a one-hour pad test.No statistically significant difference was found in terms of age, number of children, and body mass index (BMI) in patients according to the results of the 12 month postoperative stress test. We found statistically significant improvements at all control months in terms of stress test and pad weight. ICIQ-SF results showed a significant decrease at three months in patients who recovered after the operation. This rate has not changed in following control months. However, there was no statistical change in ICIQ-SF values in patients who did not recover after the operation. Conclusion: MERT seems to be one of the safe and effective modifications in the management of SUI with good one year outcomes when performed by suitably trained experienced surgeons.

Effect of the COVID-19 Pandemic on Radical Prostatectomy: A Turkish Multicenter Study.

OBJECTIVE: The present study examines the effects of the coronavirus disease 2019 pandemic on radical prostatectomy performed as part of localized prostate cancer treatment in Turkey. MATERIAL AND METHODS: A retrospective analysis was made of the data of 176 patients from 8 centers in Turkey who underwent radical prostatectomy due to localized prostate cancer over the 2 years spanning March 1, 2019, to February 28, 2021. Within this timeframe, March 1, 2019, to February 28, 2020, was denoted the 1-year pre-coronavirus disease 2019 period, while March 1, 2020, to February 28, 2021, was denoted the 1-year coronavirus disease 2019 period. An analysis was made of whether there was a difference in the number of radical prostatectomies performed for prostate cancer, the time from biopsy to operation, and the biopsy and radical prostatectomy pathology between the 2 periods. RESULTS: It was found that the number of radical prostatectomies performed for localized prostate cancer during the coronavirus disease 2019 pandemic was statistically and highly significantly fewer than in the pre-coronavirus disease 2019 period (P <.001). The patients diagnosed with Gleason 3+3 (low risk) prostate cancer were statistically significantly fewer in number in the coronavirus disease 2019 period (P <.001). The pathological Gleason score was upgrading than the biopsy Gleason score in all patients who underwent in both periods (P <.001). When the periods were compared, the pathological involvement determined by lymph node dissection performed during radical prostatectomy was found to be decreased in the coronavirus disease 2019 period, although the difference was not statistically significant (P =.051). CONCLUSION: As with many diseases, the diagnosis and treatment of prostate cancer have been adversely affected by the coronavirus disease 2019 pandemic.

Epidemiology of Nosocomial Candidemia, Mortality, and Antifungal Resistance: 7-Year Experience in Turkey.

Candidemia is an important clinical condition that prolongs hospital stays and increases morbidity, mortality, and hospital costs. The aim of this retrospective study was to evaluate the epidemiological and microbiological characteristics of patients with candidemia between January 2013 and December 2019. Two hundred forty-one episodes of candidemia were observed in 230 patients, 45% of whom were female. The median age was 63 years, and 53.9% of the episodes were in the intensive care unit (ICU). Commonly observed predisposing factors for candidemia included antibiotic use (71.3%), urinary catheterization (56.3%), central venous catheter placement (50.3%), total parenteral nutrition (47.9%), solid-organ malignancy (46%), surgery (48.6%), chemotherapy (37%), and steroid treatment (25.5%). The crude mortality rate was 52.7%. A significant difference was found between survivors and non-survivors (P = 0.007) according to the Charlson Comorbidity Index. However, no statistically significant association was found between mortality and age, sex, surgical procedure, catheter-related candidemia, or Candida spp. infection. The most frequently isolated Candida sp. was C. albicans (51%). Overall resistance rates to fluconazole, voriconazole, caspofungin, micafungin, and flucytosine were 3.7%, 0%, 2.5%, 1.8%, and 1.8%, respectively. Consequently, there is a need for tests that provide higher success rates, rapid diagnosis of candidemia, and local epidemiological data on antifungal resistance.

Clinical follow-up of patients with HBeAg positive chronic hepatitis B infection: A long-term observational study.

Background and Aim: We aimed to analyze the demographic, laboratory, and clinical characteristics of patients with HBeAg positive chronic hepatitis B infection in tertiary care centers in Istanbul. Materials and Methods: We conducted an observational cohort with ≥18-year-old patients with HBeAg positive chronic hepatitis B infection, who were followed up in three tertiary care centers in Istanbul between January 2000 and August 2018, were evaluated by reviewing electronic and recorded files. The Ethical Committee of Istanbul Medipol University approved this study (Protocol no: 10840098-604.01.01-E.44136). During the polyclinic interview, consent was obtained from patients for analysis and publication. Results: The mean age of the 64 patients was 30 (range 18-39) years, and 50% (32) of them were males. The mean follow-up period of the patients was 67 (18-180) months. Twenty-four patients were treated with at least one antiviral in their follow-up, and only 2 (3.1%) of these patients developed HBeAg seroconversion without antiviral treatment. HBeAg (+) chronic hepatitis B developed in 4 of the patients after the immune-active period. None of the patients and first-degree relatives had hepatocellular carcinoma (HCC). Conclusion: The rationality of antiviral treatment and HCC development risk in these patients still remains elusive.

Tocilizumab treatment in severe COVID-19: a multicenter retrospective study with matched controls.

Coronavirus disease-2019 (COVID-19) associated pneumonia may progress into acute respiratory distress syndrome (ARDS). Some patients develop features of macrophage activation syndrome (MAS). Elevated levels of IL-6 were reported to be associated with severe disease, and anti-IL-6R tocilizumab has been shown to be effective in some patients. This retrospective multicenter case-control study aimed to evaluate the efficacy of tocilizumab in hospitalized COVID-19 patients, who received standard of care with or without tocilizumab. Primary outcome was the progression to intubation or death. PSMATCH (SAS) procedure was used to achieve exact propensity score (PS) matching. Data from 1289 patients were collected, and study population was reduced to 1073 based on inclusion-exclusion criteria. The composite outcome was observed more frequently in tocilizumab-users, but there was a significant imbalance between arms in all critical parameters. Primary analyses were carried out in 348 patients (174 in each arm) after exact PS matching according to gender, ferritin, and procalcitonin. Logistic regression models revealed that tocilizumab significantly reduced the intubation or death (OR 0.40, p = 0.0017). When intubation is considered alone, tocilizumab-users had > 60% reduction in odds of intubation. Multiple imputation approach, which increased the size of the matched patients up to 506, provided no significant difference between arms despite a similar trend for intubation alone group. Analysis of this retrospective cohort showed more frequent intubation or death in tocilizumab-users, but PS-matched analyses revealed significant results for supporting tocilizumab use overall in a subset of patients matched according to gender, ferritin and procalcitonin levels.
