Using the Amsler Grid Test for Age-Related Macular Degeneration Screening.

Objectives: To evaluate the use of the Amsler grid test (AGT) in screening for age-related macular degeneration (AMD), one of the most common causes of blindness, in primary healthcare settings. Materials and Methods: The AGT was applied to 700 eyes of 355 people aged 50 and over who applied to a family health center in Ankara and had no eye complaints. The test was considered positive if the lines on the AGT card were seen as broken or curved, there was a difference in shape or size between the squares, or a color change or blurring was described in any area. An ophthalmologist was consulted if the AGT was positive in one or both eyes. Patients considered suitable by ophthalmologists were evaluated with optical coherence tomography. AGT results were compared with ophthalmologist examination and tomography findings in terms of AMD detection. Results: The AGT was positive in 97 (13.9%) and negative in 603 (86.1%) out of 700 eyes included in the study. A total of 184 eyes, 79 with a positive AGT and 105 eyes with a negative test, were evaluated by an ophthalmologist. As a result of examinations and tests performed by ophthalmologists, AMD was detected in a total of 67 eyes: 42 of 79 eyes with positive AGT and 25 of 105 eyes with negative AGT but referred to an ophthalmologist for different reasons. In our study, the AGT had 62.7% sensitivity and 68.4% specificity. Conclusion: The AGT is an inexpensive and easily applicable test. Although moderate sensitivity and specificity were found in our study; further studies are needed to evaluate the suitability of its use for AMD screening in primary care with limited facilities.

Application of aza-BODIPY as a Nitroaromatic Sensor.

Nitroaromatic explosive detection with high sensitivity and selectivity is requisite for civilian and military safety and the ecosystem. In this study, aza boron dipyrromethene (aza-BODIPY) dye was selected as a fluorescent-based chemosensor against nitroaromatic compounds (NACs) including 2,4,6-trinitrophenol (picric acid, TNP), 2,4,6-trinitrotoluene (TNT), and 2,4-dinitrotoluene (DNT). This dye molecule exhibits sharp fluorescent behavior with high quantum yields beyond the near-infrared region (NIR) and is considered as a potential candidate for the detection of NACs. O'Shea's approach was used to synthesize tetraphenyl-conjugated aza-BODIPY molecules. Quenching of fluorescence emission of aza-BODIPY at 668 nm after the exposure to NACs was investigated under acetonitrile-water and acetonitrile-ethanol solvent conditions. The quenching responses and its mechanism were examined by considering the Stern-Volmer relationship Stern-Volmer constants (Ksv) for TNP (in water), TNP (in ethanol), TNT, and DNT, which are predicted to be 1420, 1215, 1364, and 968 M-1, respectively, all of which are sufficiently above the limit of detection (LOD) values. Thus, the present study opens up the possibility of the usage of aza-BODIPY molecules as a low-cost, light-weight sensor for the detection of NAC explosives.

Sternocleidomastoid Muscle in Fetuses: Classification, Morphometric Analysis, and Clinical Significance.

PURPOSE: This study aimed to examine variations and morphometric properties of the sternocleidomastoid muscle (SCM) in fetuses in terms of infancy and early childhood surgeries. MATERIALS AND METHODS: Neck regions of 27 fetuses (mean age: 23.30±3.40 wk, sex: 11 boys and 16 girls) fixed with 10% formalin were dissected bilaterally. Photographs of the dissected fetuses were taken in the standard position. Morphometric measurements, such as length, width, and angle, were performed on the photographs using the ImageJ software. In addition, the origin and insertion of SCM were detected. Taking into account the studies in the literature, a classification consisting of 10 types associated with the origin of SCM was carried out. RESULTS: No statistically significant difference was observed in the parameters in terms of side and sex ( P >0.05), except from the linear distance between the clavicle and motor point where the accessory nerve enters SCM (20.10±3.76 for male, 17.53±4.05 for female, P =0.022). Two-headed SCM (Type 1) was detected in 42 out of 54 sides. Two-headed clavicular head (Type 2a) was detected on 9 sides, and 3-headed (Type 2b) on 1 side. A 2-headed sternal head (Type 3) was detected on 1 side. A single-headed SCM (Type 5) was also detected on 1 side. CONCLUSION: Knowledge related to variations of the origin and insertion of fetal SCM may be helpful in preventing complications during treatments of pathologies such as congenital muscular torticollis in early period of life. Moreover, the calculated formulas may be useful to estimate the size of SCM in newborns.

Comparison of 2-year follow-up outcomes of laparoscopic lateral suspension and sacrospinous fixation in apical compartment prolapse: an observational study.

PURPOSE: This study aimed to compare the results of patients with laparoscopic lateral suspension (LLS) and sacrospinous fixation (SSF). METHODS: This prospective observational study included 52 patients who underwent LLS and 53 patients who underwent SSF due to pelvic organ prolapse. The pelvic organ prolapse's anatomical cure and the frequency of recurrence have been recorded. Female Sexual Function Index, Pelvic Organ Prolapse Symptom Score, and complications were evaluated preoperatively and at the postoperative 24th month. RESULTS: In the LLS group, the subjective treatment rate was 88.4% and the anatomical cure rate for apical prolapse was 96.1%. In the SSF group, the subjective treatment rate was 83.0% and the anatomical cure rate for apical prolapse was 90.5%. There was a significant difference between the groups regarding Clavien-Dindo classification and reoperation (p < 0.05). Female Sexual Function Index, and the Pelvic Organ Prolapse Symptom Score were different between the groups (p < 0.05). CONCLUSIONS: This study showed that there is no difference between two surgical techniques in apical prolapse cure rates. However, the LLS seem preferable in terms of the Female Sexual Function Index, Pelvic Organ Prolapse Symptom Score, reoperation, and complications. We need larger sample size studies in terms of incidence of complications and reoperation.

An evaluation of the use of inhalers in asthma and chronic obstructive pulmonary disease.

Objectives: Inhaled therapy is the treatment of choice for obstructive lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). However, the maximum benefit from such therapy depends on the correct use of inhaler devices. In this study, our primary aim was to evaluate inhaler techniques in patients with asthma and COPD in order to identify common errors. In addition, we investigated the effect of various parameters on the rate of inhaler misuse. Methods: We enrolled a total of 300 asthma/COPD patients, who presented at the Chest Diseases and Family Medicine Outpatient Clinics of a tertiary hospital located in Ankara, Turkey. We used a face-to-face survey that included questions about sociodemographic features and inhaler therapy. Subsequently, we requested patients to demonstrate how they use their inhalers and assessed their inhalation technique according to checklists. Results: Of the 300 patients, 70.2% used their inhaler drugs incorrectly. The rate of misuse among metered dose inhaler (MDI) users was significantly higher than those using dry powder inhalers (DPIs) (77.6% vs 64%; p = 0.002). When DPI devices were analyzed, the rates of misuse were significantly higher in Handihaler users (p = 0.012) and Diskus inhaler users (p = 0.009) when compared to Sanohaler users. Gender, type of disease (asthma/COPD), duration of inhaler use, and duration of illness had no impact on the rate of misuse. However, an advanced age (>60 years old), a level of education lower than high school, and the use of MDI were all identified as factors associated with misuse. The most common mistake was 'failing to breath out before inhalation' for all types of devices (for MDI: 66.7%, and for DPI: 71.1-82.8%). Conclusions: The rate of inhaler drug misuse was high. The identification of factors associated with misuse could provide information to implement appropriate actions to reduce the rates of misuse.

Identification of a 3-(5-methyl-2-thiazolylamino)phthalide as a new minor groove agent.

A new 3-(5-methyl-2-thiazolylamino)phthalide molecule, 3-((5-methylthiazol-2-yl)amino)isobenzofuran-1(3H)-one, was synthesized and characterized experimentally by FT-IR, NMR, UV-Vis, and single-crystal X-ray analysis and theoretically by quantum chemical calculations. The single-crystal X-ray studies revealed that the compound crystallizes in the monoclinic space group P-21/c with unit-cell parameters a = 8.0550(6) Å, b = 6.1386(3) Å, c = 23.3228(18) Å, ß = 97.724(6)° and Z = 4. Optimized geometries and the vibrational frequencies were studied at the density functional theory (DFT) level by using the hybrid functional B3LYP with a 6-311 G (d,p) basis set. The title compound was evaluated for its anti-quorum sensing (anti-QS) activity on Chromobacterium violaceum 12472 and additionally for its antibacterial activity against Staphylococcus aureus 29213, Staphylococcus epidermidis 12228, Pseudomonas aeruginosa 27853, Escherichia coli 25922, and Proteus mirabilis 14153. The lowest MIC value was 0.24 µg/mL for S. aureus 29213 and the highest MIC value was 30.75 µg/mL for E. coli 25922. While anti-bacterial activity was observed in those other than the S. epidermidis and P. Mirabilis, anti-QS activity wasn't detected. Investigations on dsDNA binding affinity indicate that the title compound binds to dsDNA via the groove binding mode. Molecular docking calculations and molecular dynamics simulations results showed also that the title compound prefers binding to the minor groove of dsDNA and remains stable in the minor groove throughout the molecular dynamics simulation.Communicated by Ramaswamy H.

Serum kisspeptin levels in deep-infiltrating, ovarian, and superficial endometriosis: A prospective observational study.

The diagnosis of endometriosis may delay for many years due to non-deterministic symptoms and avoiding surgical interventions. Kisspeptins are hormones that interact with endometrial tissue to limit invasions during placentation and various cancers and are suggested to be also associated with endometriosis. This study evaluated if serum kisspeptin levels are associated with the invasion depth in endometriosis. Forty patients between 18 and 45 years of age and admitted to a tertiary-care Obstetrics and Gynecology Department between 2020 and 2021 with a diagnosis of endometriosis, and 40 patients without endometrioma were included in the study. Demographic, obstetric, clinical, and biochemical characteristics were evaluated in patients with superficial (SE) and deep infiltrating (DIE) endometriosis and healthy controls. Twenty patients (50%) had SE, 14 (35%) had DIE, and 22 (55%) had endometrioma in the patient group. Fertility rates were higher among controls, but similar between patients with SE and DIE. CA125 levels were significantly higher in the DIE group. SE and DIE groups had similar kisspeptin values, significantly higher than controls. CA125 and kisspeptin levels were not correlated in study groups. Serum kisspeptin levels were significantly different between endometriosis patients and healthy controls. However, kisspeptin levels were unable to differentiate endometriosis severity. Our results suggest that kisspeptins might play a role in the pathogenesis of endometriosis, which needs further assessment in more comprehensive studies.

Ovarian Reserve and Pelvic Ultrasound Assessment in Familial Mediterranean Fever.

Introduction Familial Mediterranean fever (FMF) is an inflammatory rheumatic disease that affects people in their reproductive period. The aim of this study was to investigate the number of gravida, ovarian reserve, and ovarian doppler characteristics in FMF patients. Methods The study design is cross-sectional. Between November 1, 2018, and October 31, 2019, 40 FMF patients, and 40 age-matched volunteers were included in the study. Early follicular phase follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E2), progesterone, and anti-Mullerian hormone (AMH) levels, as well as ovarian volume, antral follicle count (AFC), ovarian stromal artery doppler findings, and pelvic pathologies, were evaluated. Results The number of gravida, and the AFC was significantly higher in the control group (16.00 ± 5.22) compared to the patients with FMF (13.00 ± 4.09) (p = 0.026). LH values were significantly higher in the FMF group. Thirteen patients (32.5%) received anakinra and colchicine, and 27 patients (67.5%) received only colchicine. There was no significant difference between the patients receiving anakinra, and the patients receiving colchicine in terms of AMH, FSH, AFC, and E2 values. Conclusion FMF patients were found to have low gravida and AFC, and a significant portion was observed to have pelvic fluid and hydrosalpinx. In conclusion, the presence of pelvic fluid, hydrosalpinx, and low AFC persist in FMF patients despite colchicine and/or anti-interleukin-1 treatments. The low gravida may be related to these pathologies detected in patients with FMF.

Anti-osteoporotic Drug Utilization Rates for Secondary Prevention Among Patients with Osteoporotic Fractures.

OBJECTIVES: Anti-osteoporotic drugs (AOD) are essential for secondary prevention of osteoporotic fracture (OF) in patients with established osteoporosis. However, data about AOD utilization rates are scarce among patients with OF. This study was therefore aimed at determining the AOD utilization rates among those particularly vulnerable patients. MATERIALS AND METHODS: This cross-sectional study followed the medical records of patients with OF starting from their first OF diagnosis date. Each patient's preventive osteoporosis treatments (vitamin D, calcium+vitamin D) and AOD utilization rate were recorded for a 12-month period following OF diagnosis. RESULTS: A total of 210 patients (168 females, mean age: 67.8±11.9 years; 42 males, mean age 62.4±16.1 years) were enrolled in the study. Of these, 65.7% (n=138) did not use any medication for primary protection against osteoporosis before OF diagnosis. The ratio of patients not using any type of medication for secondary prevention after OF increased from 26.5% to 51% during a 12-month period. In addition, by one year following diagnosis, AOD usage rate had decreased from 62.3% to 41.3%. CONCLUSION: The AOD usage rates for secondary prevention of OF were insufficient, and cessation rates were high. Identification of factors associated with decreased AOD utility rates will provide important information for guiding patient follow-up in order to reduce the occurrence of OF.

COVID-19 disease does not cause ovarian injury in women of reproductive age: an observational before-and-after COVID-19 study.

RESEARCH QUESTION: Can the SARS-CoV-2 virus injure the ovaries? DESIGN: An observational before-and-after COVID-19 study at an academic medical centre. A total of 132 young women aged 18-40 were enrolled; they were tested for reproductive function in the early follicular phase, and their information was obtained from hospital data between January 2019 and June 2021. Serum FSH, LH, oestradiol, the ratio of FSH to LH and anti-Müllerian hormone (AMH) concentrations were measured for each patient both before and after COVID-19 disease. RESULTS: In women with unexplained infertility, the median serum AMH concentrations (and ranges) were 2.01 ng/ml (1.09-3.78) and 1.74 ng/ml (0.88-3.41) in the pre-COVID-19 disease and post-COVID-19 disease groups, respectively. There was no statistically significant difference in terms of serum concentrations of AMH between pre- and post-illness (P = 0.097). Serum FSH, LH, FSH/LH ratio and oestradiol concentrations of the patients before COVID-19 illness were similar to the serum concentrations of the same patients after COVID-19 illness. CONCLUSION: According to these study results and recent studies investigating the effect of COVID-19 on ovarian reserve, it is suggested that the SARS-CoV-2 virus does not impact ovarian reserve; however, menstrual status changes may be related to extreme immune response and inflammation, or psychological stress and anxiety caused by the COVID-19 disease. These menstrual status changes are also not permanent and resolve within a few months following COVID-19 illness.

Does high estrogen level negatively affect pregnancy success in frozen embryo transfer?

Introduction: High estrogen levels could reduce pregnancy rates by disrupting the implantation of the embryo into the endometrium in patients treated with fresh cycles of in vitro fertilization. The aim of the present study was to investigate the effect of estrogen levels on the pregnancy and abortion rate in autologous frozen embryo transfer with hormone replacement therapy (HRT). Material and methods: A historical cohort study was conducted in an academic setting to investigate the effect of estrogen levels on the pregnancy and abortion rates for all autologous artificial frozen embryo transfer cycles performed from January 2016 to January 2018. Serum estradiol levels recorded on day 2 or 3 of the cycle were stated as e1, and levels recorded on the day of progesterone were indicated as e2. Human chorionic gonadotropin (ß-hCG) positivity, which was examined 14 days after the transfer, was used to evaluate biochemical pregnancy. Abortion was defined as the termination of pregnancy before the 20th gestational week. Results: There were 130 patients with unexplained infertility, 20 patients with poor ovarian reserve, and 54 patients with male factor. Of the patients with unexplained infertility, poor ovarian reserve, and male factor, 58, 4, and 27 of them were pregnant, respectively. No statistically significant difference was found between the e1 and e2 levels of the pregnant and non-pregnant groups (p = 0.273, p = 0.219). In addition, there was no statistically significant difference between e2 levels in terms of the abortion rate (p = 0.722). Conclusions: In autologous frozen embryo transfer with HRT, estrogen levels did not have a significant effect on the pregnancy or abortion rate. Therefore, estrogen levels do not need to be monitored in frozen embryo transfer with HRT.

Vaccination status among patients with the need for emergency hospitalizations related to COVID-19.

BACKGROUND: It is thought vaccines allowed for emergency use significantly reduce hospitalizations and emergency room visits. It is a matter of curiosity how many of the patients who come to the emergency department (ED) are vaccinated. We aimed to examine the characteristics of ED patients needing hospitalizations related to moderate and severe COVID-19 by vaccination status. METHODS: A retrospective study of 559 rRT-PCR-confirmed SARS-CoV-2 infection cases with moderate or severe COVID-19 needing hospitalization was performed in August 2021. Univariate and multivariate logistic regression analyses were performed for factors associated with mortality. RESULTS: The mean age of the patients was 60.8 ± 18.1 years old, and 54.2% (n = 303) of the patients were women. The most common comorbidities were hypertension (37.2%), diabetes mellitus (31.1%) and chronic obstructive pulmonary disease (13.8%), respectively. The number of patients with alpha variant was 399 (71.4%), and delta variant was 83 (14.8%). Fifty point 6% (n = 283) of the patients were fully vaccinated. The total number of patients who died in the study was 114 (20.4%), and the number of patients hospitalized in the intensive care unit was 168 (30.1%). The day between the last dose of vaccine and hospitalization was 117 ± 45.9 days. In multivariate logistic regression analysis: age (odds ratio (OR), 1.05; 95% confidence intervals (95% CI) 1.03-1.08- year increase), male gender (OR, 1.8; 95% CI, 1.1-2.9), presence of at least one comorbid disease (OR, 2; 95% CI, 1.1-3.7) and partial (OR, 0.24;95% CI, 0.09-0.6) and fully vaccinated status (OR, 0.1; 95% CI, 0.05-0.18) were associated with mortality among COVID-19 patients. CONCLUSIONS: In this study, age older than 65, unvaccinated, and comorbidities had significantly higher mortality. In multivariate regression analyses, age, vaccination status, comorbidities and the male gender were associated with mortality. Our study did not evaluate the vaccine efficacy but, a lower mortality rate was observed in those fully vaccinated with CoronaVac and Pfizer-BioNTech. Additionally, Alpha, Delta and other variants had the same mortality rates.

Arnold Kirkpatrick Henry (1886-1962) and his eponym (Master Knot of Henry): a narrative review.

PURPOSE: The aims of this review were to form a more precise description for Master Knot of Henry (MKH), and to modify classifications related to interconnections between flexor hallucis longus (FHL) and flexor digitorum longus (FDL) for showing all configurations in the literature. METHODS: A literature search was performed in main databases to obtain information related to anatomical definitions and variations of MKH. The search was carried out using the following keywords: "Master Knot of Henry", "Chiasma plantare", "Flexor hallucis longus" and "Flexor digitorum longus". Information extracted from the studies was: sample size, numerical values, classifications, variation types, incidence of types, anatomical definitions of MKH, year of publication, and type of study. RESULTS: This study proposes that MKH should be defined as the intersection territory where FDL crosses over FHL in the plantar foot. The postchiasmatic plantar area located at distal to MKH (the narrow space between MKH and the division of FDL) should be termed as the triangle of Henry. Moreover, the classification systems showing different configurations related to interconnections situated at Henry's triangle were updated as eight types to present all forms in the literature. CONCLUSION: Our definitions may assist in determining the precise anatomical boundaries of MKH, and thus facilitate the use of MKH as a surgical landmark. In addition, our modified classification systems covering all variations in the current literature may be helpful for surgeons and anatomists to understand formations of the triangle of Henry, and the long flexor tendons of the lesser toes.

Comparison of CURB-65 Pneumonia Severity Score, Quick COVID-19 Severity Index, and Brescia-COVID Respiratory Severity Scale in Emergently Hospitalized COVID-19 Patients with Pneumonia.

Objective: This study aimed to assess the performance of the CURB-65, the quick COVID-19 severity index (qCSI), and the Brescia-COVID respiratory severity scale (BCRSS) scores in predicting ICU (intensive care unit) hospitalization and in-hospital mortality in emergently hospitalized patients with COVID-19 pneumonia. Materials and Methods: We retrospectively reviewed the emergently hospitalized 258 patients with COVID-19 pneumonia consecutively. The required sample size was calculated to compare the areas under the two ROC (receiver operating characteristic) curves (AUC) using the MedCalc 20.0 program (MedCalc Software Ltd., Ostend, Belgium). In addition, we actualized ROC analyses of the CURB-65, the qCSI, and the BCRSS scores and compared the ROC curves of these three scores. Results: The median age of the patients was 73, and 63.6% (n=164) were male. Of 258 patients, 29.5% (n=76) were hospitalized in the intensive care unit (ICU), and 15.9% (n=41) died. The CURB-65 and the qCSI scores predicted ICU admission at a moderate level (p≤0.001; AUC values were 0.743 and 0.723, respectively). However, the predictive effect of the BCRSS score for ICU admission was lower (p≤0.001; AUC value was 0.667). The CURB-65 predicted in-hospital mortality at a moderate level ( p≤0.001; AUC value was 0.762). However, the predictive effect of the qCSI and the BCRSS scores for in-hospital mortality were lower ( p≤0.001 and p=0.012, respectively; AUC values were 0.655 and 0.612, respectively). Conclusion: The CURB-65 score predicted ICU hospitalization and in-hospital mortality better than the qCSI and the BCRSS scores. Also, the qCSI score predicted ICU admission better than the BCRSS score.The predictive effect of the BCRSS score was the lowest. We recommend future studies to evaluate the value and utility of COVID-19 risk classification models.

X-ray nanotomography and electron backscatter diffraction demonstrate the crystalline, heterogeneous and impermeable nature of conodont white matter.

Conodont elements, microfossil remains of extinct primitive vertebrates, are commonly exploited as mineral archives of ocean chemistry, yielding fundamental insights into the palaeotemperature and chemical composition of past oceans. Geochemical assays have been traditionally focused on the so-called lamellar and white matter crown tissues; however, the porosity and crystallographic nature of the white matter and its inferred permeability are disputed, raising concerns over its suitability as a geochemical archive. Here, we constrain the characteristics of this tissue and address conflicting interpretations using ptychographic X-ray-computed tomography (PXCT), pore network analysis, synchrotron radiation X-ray tomographic microscopy (srXTM) and electron back-scatter diffraction (EBSD). PXCT and pore network analyses based on these data reveal that while white matter is extremely porous, the pores are unconnected, rendering this tissue closed to postmortem fluid percolation. EBSD analyses demonstrate that white matter is crystalline and comprised of a single crystal typically tens of micrometres in dimensions. Combined with evidence that conodont elements grow episodically, these data suggest that white matter, which comprises the denticles of conodont elements, grows syntactically, indicating that individual crystals are time heterogeneous. Together these data provide support for the interpretation of conodont white matter as a closed geochemical system and, therefore, its utility of the conodont fossil record as a historical archive of Palaeozoic and Early Mesozoic ocean chemistry.

Spray Freeze Dried Lyospheres® for Nasal Administration of Insulin.

Pharmacologically active macromolecules, such as peptides, are still a major challenge in terms of designing a delivery system for their transport across absorption barriers and at the same time provide sufficiently high long-term stability. Spray freeze dried (SFD) lyospheres® are proposed here as an alternative for the preparation of fast dissolving porous particles for nasal administration of insulin. Insulin solutions containing mannitol and polyvinylpyrrolidone complemented with permeation enhancing excipients (sodium taurocholate or cyclodextrins) were sprayed into a cooled spray tower, followed by vacuum freeze drying. Final porous particles were highly spherical and mean diameters ranged from 190 to 250 µm, depending on the excipient composition. Based on the low density, lyospheres resulted in a nasal deposition rates of 90% or higher. When tested in vivo for their glycemic potential in rats, an insulin-taurocholate combination revealed a nasal bioavailability of insulin of 7.0 ± 2.8%. A complementary study with fluorescently labeled-dextrans of various molecular weights confirmed these observations, leading to nasal absorption ranging from 0.7 ± 0.3% (70 kDa) to 10.0 ± 3.1% (4 kDa). The low density facilitated nasal administration in general, while the high porosity ensured immediate dissolution of the particles. Additionally, due to their stability, lyospheres provide an extremely promising platform for nasal peptide delivery.

Impact of a high visceral adiposity index on female sexual dysfunction in sexually active women? Results of a cross-sectional study.

AIMS: To our knowledge, this is the first study investigating the impact of high visceral adiposity index (VAI) on female sexual dysfunction (FSD). We aimed to show the impact of increased levels of VAI on FSD compared with body mass index (BMI) and waist circumference (WC) particularly in those with metabolic syndrome (MeTS). METHODS: We included 158 participants in two groups: Group 1 (n = 68 with normal sexual function) and Group 2 (n = 90 with sexual dysfunction). Demographic, clinic data, presence of MeTS and comorbidities were recorded. The BMI, WC and the VAI were calculated. Sexual function was assessed using the female sexual function index. RESULTS: The mean age and all the anthropometric variables were similar between the groups (P > .05). MeTS was associated with lower arousal and lubrication scores than those without MeTS (P = .023). The higher VAI was associated with lower desire, lubrication and orgasm scores (P < .05). Each integer increase of the VAI weakly predicted decrease of desire (P = .015), arousal (P = .015), lubrication (P = .005) and satisfaction (P = .046). The WC and BMI were not a good predictor for FSD in women (OR=1.019, P = .318). CONCLUSION: The VAI was linked with lower scores in some female sexual function subdomains, but the correlation coefficient was low, indicating a weak association. Further studies with a higher number of participants are needed to conclude that the VAI may increase the risk of FSD, particularly in patients with MeTS.

Effect of supraphysiological estrogen levels on arterial stiffness and hemodynamic parameters.

OBJECTIVE: The present study evaluates the arterial stiffness and hemodynamic parameters in patients with a supraphysiological estrogen level due to in vitro fertilization (IVF) with controlled ovarian hyperstimulation (COH). METHODS: A total of 82 female patients aged 24-45 years were included. Their arterial stiffness parameters were analyzed before and after the appropriate COH protocol involving arteriography using Mobil-O-Graph NG (IEM GmbH, Stolberg, Germany) 24-hour ambulatory blood pressure monitor. RESULTS: Systolic, diastolic, mean, central systolic, and diastolic blood pressures, as well as peripheral vascular resistance, were significantly lower after COH therapy (p=0.001, 0.002, <0.001, <0.001, 0.040, and <0.001, respectively). In contrast, there was no statistically significant difference observed in heart rate, pulse pressure, or cardiac output. The pulse wave velocity measurement was significantly lower after COH than the baseline levels [5.3 m/s (4.5-6.9 m/s) versus 5.4 m/s (4.7-7.3 m/s,); p<0.001], but the augmentation index was not significantly different [28% (4%-41%) versus 29% (5%-43%); p=0.090]. When the patients were grouped according to the occurrence of a pregnancy after IVF therapy, all parameters were not different between the pregnancy (+) and pregnancy (-) patients (p>0.05). CONCLUSION: Arterial stiffness and hemodynamic parameters significantly decreased in IVF patients who underwent COH therapy. The long-term clinical significance of this short-term effect should be investigated with prospective studies. There was no significant difference in all parameters before and after COH when the pregnancy (+) and pregnancy (-) patients were compared.

Inappropriate Prescribing of Proton Pump Inhibitors in Outpatient Clinics.

Proton pump inhibitors are the commonly prescribed drugs for acid-related disorders. However, many of those prescriptions are inappropriate in inpatient and outpatient settings according to the recommended guidelines. Many studies have been conducted in inpatient clinics, but data about the appropriateness of proton pump inhibitor prescribing in outpatient clinics are scarce. Therefore, the aim of this study was to determine inappropriate proton pump inhibitor prescribing rates among patients admitted to a tertiary hospital family medicine outpatient clinic. A total of 259 patients (median age = 59 years; 72.6% women) were enrolled into the study and 35.9% of them had no proper indications to utilize proton pump inhibitors. Inappropriate proton pump inhibitor usage rate was significantly higher in patients older than 60 years compared with their younger counterparts (62.4% vs. 37.6%; p = .001). The most frequent reason to use a proton pump inhibitor with nonapproved indications was polypharmacy (41.9%). Despite endoscopic evaluation, 41.9% of the patients received a proton pump inhibitor without an approved indication. A significant proportion of nonindicated prescriptions were a consequence of continued prescribing without re-evaluating patients in outpatient clinics. Consideration of proton pump inhibitor indications according to the guidelines in every admission may prevent inappropriate prescriptions.

Is Spontaneous Pneumomediastinum a Poor Prognostic Factor in Covid-19?

OBJECTIVE: To determine the risk factors for spontaneous pneumomediastinum (SPM), its clinical course and effect on prognosis in patients with Coronavirus disease-19 (COVID-19) pneumonia. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Kayseri City Training and Research Hospital, Turkey, from April  to September 2020. METHODOLOGY: All COVID-19 patients' clinical, laboratory, and radiologic characteristics, as well as treatment outcome data, were obtained through medical record extraction. Group A had 50 patients (22 men and 28 women) without SPM, and Group B had 20 patients (10 men and 10 women) with SPM. RESULTS: Considering the accompanying comorbidities, the frequencies of asthma and inhaler-use was significantly higher in Group B than in Group A (p <0.05). In the CT evaluation at presentation, the rate of involvement of all five lobes of the lung in Group B was significantly higher than in Group A. Rates of tube thoracostomy, mechanical ventilator requirement, length of stay in hospital, and exitus were significantly higher in Group B than in Group A (p <0.05). CONCLUSION: SPM development in a patient with COVID-19 pneumonia is a sign that the prognosis will not be good, and these patients need a more aggressive treatment.
