ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2024. [PMID: 38477149 DOI: 10.1002/uog.27641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 02/06/2024] [Accepted: 02/22/2024] [Indexed: 03/14/2024]
Abstract
OBJECTIVE This study aimed to externally and prospectively validate the International Ovarian Tumor Analysis (IOTA) Simple Rules (SRs), Logistic Regression model 2 (LR2) and Assessment of Different NEoplasias in the adneXa (ADNEX) in a Portuguese population, comparing them with operator subjective assessment (SA), Risk-of-Malignancy Index (RMI), as well as with each other. This study also aimed to retrospectively validate IOTA two-step strategy, using modified benign descriptors (MBDs) followed by the application of ADNEX in cases where MBDs were not applicable (MBDs + ADNEX). METHODS In this multicenter diagnostic accuracy study, conducted between January 2016 and December 2021, three tertiary referral centers prospectively included consecutive patients with ultrasound diagnosis of at least one adnexal tumor who underwent surgery. All ultrasound assessments were performed by level II or III sonologists with IOTA certification. Patient clinical data and serum cancer antigen (CA125) levels were collected from the hospital databases. Each adnexal mass was classified as benign or malignant using SA, RMI, IOTA SRs, LR2 and ADNEX (with and without CA125). The reference standard was histopathological diagnosis. In the second phase, all adnexal tumors were retrospectively classified using the two-step strategy (MBDs + ADNEX). The sensitivity, specificity, positive (PPV) and negative predictive value (NPV), positive (LR+) and negative likelihood ratio (LR-) as well as overall accuracy were determined for SA, RMI, IOTA SRs, LR2, ADNEX and two-step strategy (MBDs + ADNEX). Receiver-operator characteristic curves were constructed and corresponding areas under the curve (AUC) determined for RMI, LR2 and ADNEX and two-step strategy (MBDs + ADNEX). The ADNEX calibration plots were constructed and estimated by LOESS smoother. RESULTS Of the 571 included patients, 428 had benign disease, 42 borderline ovarian tumors, 93 primary invasive adnexal cancers and 8 metastatic tumors in adnexa (malignancy prevalence: 25.0%). The operator SA had an overall sensitivity of 97.9% and a specificity of 83.6% for distinguishing between benign and malignant lesions. RMI showed high specificity (95.6%) but very low sensitivity (58.7%), with an AUC of 0.913. The IOTA SRs were applicable in 80.0% of patients, with a sensitivity of 94.8% and a specificity of 98.6%. LR2 revealed a sensitivity of 84.6%, a specificity of 86.9% and an AUC of 0.939, at the malignancy risk cut-off of 10%. At the same cut-off, ADNEX with and without CA125 had a sensitivity of 95.8% and 98.6%, respectively, and a specificity of 82.5% and 79.7%, respectively. The AUC of ADNEX with vs. without CA125 was 0.962 vs. 0.960. The ADNEX model provided heterogeneous results in distinguishing between benign and different subtypes of malignancy, with the highest AUC (0.991) for discriminating benign masses from primary adnexal cancer stage II-IV, and the lowest AUC (0.696) for distinguishing primary adnexal cancer stage I and metastatic lesion in adnexa. The ADNEX calibration plots suggested an underestimation of the predicted risk in relation with the observed proportion of malignancies. The MBDs were applicable in 26.3% of cases (150/571 tumors, none of which were malignant). Similar to the ADNEX model applied in all patients, the two-step strategy using ADNEX in the second step only, with and without CA125, had an AUC of 0.964 and 0.961, respectively. CONCLUSIONS Our results showed a good to excellent performance of the IOTA methods in the studied Portuguese population, outperforming RMI. ADNEX was superior in accuracy, but interpretation of its ability to distinguish malignant subtypes was fundamentally limited not only by sample size but also by large differences in the prevalence of tumor subtypes. The IOTA MBDs have been shown to be reliable in identifying benign disease. The two-step strategy based on the application of MBDs, followed by the ADNEX model if MBDs are not applicable, has proven to be suitable for daily practice circumventing the need to use electronic support in all patients.

The impact of the COVID-19 pandemic on the trend of prescribing long-acting injections of paliperidone and risperidone in Central Serbia. Front Psychiatry 2023; 14:1301835. [PMID: 38179245 PMCID: PMC10764607 DOI: 10.3389/fpsyt.2023.1301835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 11/24/2023] [Indexed: 01/06/2024] Open
Abstract
Since the end of 2019, the global spread of COVID-19 has represented a historic event that changed our way of treating patients globally. The use of long-acting injections (LAI) antipsychotics was emphasized. Our goal was to investigate the impact of COVID-19 on the frequency of prescribing LAI and compare it with a period before. All patients (198) who started LAI-risperidone or LAI-paliperidone for the period 2017-2022, in Kragujevac, the city in Central Serbia, were considered. The frequency of prescribing LAI before and during COVID-19 and the total number of prescribed LAI per year were compared. Separately, the frequency of prescribing LAI-R and the frequency of prescribing LAI-P were compared. The significant (p < 0,05) increase in the use of LAI risperidone and paliperidone was in 2020 and 2021 [per year 2017(3), 2018(6), 2019(26), 2020(75), 2021(55), and 2022(33)]. The significant (p < 0,05) increase in monthly and quarterly preparations of LAI paliperidone was in 2020 and 2021 relative to the years before the pandemic. As the pandemic weakened, the inclusion of LAI paliperidone therapy weakened during 2022. A significant increase in usage of LAI risperidone was in 2022, and in 2020 and 2021 was as it was in the period 2017-2019. During COVID-19, especially in years when COVID-19 restriction measures were stricter, there was a significant change in the application method of antipsychotic therapy in favor of LAI. Regardless of the increase in treatment costs, patients' interests and protection were prioritized in the treatment process.

The routes of hysterectomy: A survey of current practices amongst members of the International Society for Gynaecologic Endoscopy (ISGE). Eur J Obstet Gynecol Reprod Biol 2023; 291:99-105. [PMID: 37857149 DOI: 10.1016/j.ejogrb.2023.10.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 10/02/2023] [Accepted: 10/12/2023] [Indexed: 10/21/2023]
Abstract
OBJECTIVE This study aimed to explore the current opinion on the routes of hysterectomy amongst the members of the International Society for Gynaecologic Endoscopy (ISGE), as well as the perceptions of potential barriers that inhibit gynaecologists from offering a minimally invasive hysterectomies (MIHs) to their patients. STUDY DESIGN An anonymous, electronic survey was designed, including the questions about the surgeon location and length of gynaecological practice, preferred approach to hysterectomy, approximate number of surgical cases performed during the year preceding the survey (2021), and potential barriers and contraindications to performing MIHs. It was validated by 12 practicing gynaecologists. Subsequently, the survey was sent to all practicing gynaecologists who are the members of the ISGE. RESULTS We received a response from 159 members of ISGE (29 % response rate), of which 92 % with ≥ 5 years in practice since the completion of their residency training in Gynaecology and Obstetrics. When asked about the preferred route of hysterectomy for themselves or their relatives, 59 % chose total laparoscopic hysterectomy (TLH), 19 % vaginal hysterectomy (VH), 8 % chose laparoscopically-assisted vaginal hysterectomy (LAVH) and 5 % chose total abdominal hysterectomy (TAH). However, TAH was the most performed hysterectomy procedure undertaken by the respondents in the year preceding the survey. When asked about the main obstacles to performing MIHs, more than half of the respondents highlighted insufficient training during residency and insufficient surgical experience. Only 25 % of the responders acknowledged reading the ISGE guidelines on performing vaginal hysterectomy. CONCLUSIONS Contrary to a full understanding of the benefits of MIHs, lack of training, as well as insufficient surgical experience and unawareness of existing evidence-based guidelines were the main reasons for the high rate of TAH among the ISGE members who participated in the study. All efforts should be directed at teaching VH and TLH techniques during residency, continuous acquisition of practical experience, and use of validated patient selection guidelines for MIH in daily clinical practice.

The impact of obesity on vaginal hysterectomy and laparoscopically-assisted vaginal hysterectomy outcomes: A randomised control trial. Eur J Obstet Gynecol Reprod Biol 2023; 287:227-231. [PMID: 37390756 DOI: 10.1016/j.ejogrb.2023.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 01/29/2023] [Accepted: 06/01/2023] [Indexed: 07/02/2023]
Abstract
OBJECTIVES This prospective randomised control trial aimed to compare outcome measures of vaginal hysterectomy (VH) and laparoscopically-assisted vaginal hysterectomy (LAVH) in obese vs. non-obese women undergoing hysterectomy for benign uterine conditions with a non-prolapsed uterus. The primary objective of the study was to estimate operation time, uterine weight and blood loss amongst obese and non-obese patients undergoing VH and LAVH. The secondary objective was to determine any difference in hospital stay, the need for post-operative analgesia, intra- and immediate post-operative complications, and the rate of conversion to laparotomy for obese vs. non-obese patients undergoing VH and LAVH. STUDY DESIGN A prospective randomised control study was undertaken in the Department of Obstetrics and Gynaecology of the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH). Women admitted between January 2017 and December 2019 for hysterectomy due to benign conditions, meeting the inclusion criteria set by the unit (vaginally accessible uterus, uterine size ≤ 12 weeks of gestation or ≤ 280gr on ultrasound examination, pathology confined to the uterus) were included in the study. The VH procedures were performed by the residents in training, under the supervision of specialists with large experience in vaginal surgery. All the LAVHs were performed by one surgeon (AC). In addition to the patient characteristics and surgical approach to hysterectomy, operative time, estimated blood loss, uterine weight, length of hospital stay, intra-operative and immediate post-operative complications were also recorded in obese and non-obese patient groups and comparatively analysed. RESULTS A total of 227 women were included in the study. 151 patients underwent VH and 76 LAVH, upon randomisation on a 2:1 basis, reflecting the habitual proportion of hysterectomy cases in the Urogynaecology and Endoscopy Unit at CMJAH. No significant differences were found in mean shift of pre-operative to post-operative serum haemoglobin, uterine weight, intra- and immediate post-operative complications, and convalescence period when comparing obese and non-obese patients in both the VH and LAVH groups. There was a statistically significant difference in operating time between the two procedures. The LAVHs took longer compared to the VHs to be performed (62.8 ± 9.3 vs. 29.9 ± 6.6 min in non-obese patients, and 62.7 ± 9.8 vs 30.0 ± 6,9 min for obese patients). All VHs and LAVHs were successfully accomplished without major complications. CONCLUSION VH and LAVH for the non-prolapsed uterus is a feasible and safe alternative for obese patients demonstrating similar perioperative outcome measures as non-obese women undergoing VH and LAVH. Where possible, VH should be preferred to LAVH as it is a safe route of hysterectomy, with operation time being significantly shorter.

Abstract
There is emerging evidence of prolonged recovery in survivors of coronavirus disease 2019 (COVID-19), even in those with mild COVID-19. In this paper, we report a case of a 39-year-old male with excessive body weight and a history of borderline values of arterial hypertension without therapy, who was mainly complaining of progressive dyspnea after being diagnosed with mild COVID-19. According to the recent guidelines on the holistic assessment and management of patients who had COVID-19, all preferred diagnostic procedures, including multidetector computed tomography (CT), CT pulmonary angiogram, and echocardiography, should be conducted. However, in our patient, no underlying cardiopulmonary disorder has been established. Therefore, considering all additional symptoms our patient had beyond dyspnea, our initial differential diagnosis included anxiety-related dysfunctional breathing. However, psychiatric evaluation revealed that our patient had only a mild anxiety level, which was unlikely to provoke somatic complaints. We decided to perform further investigations considering that cardiopulmonary exercise test (CPET) represents a reliable diagnostic tool for patients with unexplained dyspnea. Finally, the CPET elucidated the diastolic dysfunction of the left ventricle, which was the most probable cause of progressive dyspnea in our patient. We suggested that, based on uncontrolled cardiovascular risk factors our patient had, COVID-19 triggered a subclinical form of heart failure (HF) with preserved ejection fraction (HFpEF) to become clinically manifest. Recently, the new onset, exacerbation, or transition from subclinical to clinical HFpEF has been associated with COVID-19. Therefore, in addition to the present literature, our case should warn physicians on HFpEF among survivors of COVID-19.

Abstract
In our paper we aimed to increase the awareness among physicians, concerning coronavirus disease 2019 (COVID-19) severity, especially in patients with specific underlying comorbidities. Obesity is the second most common condition in hospitalized COVID-19 patients. Furthermore it has a major role in the development of obstructive sleep apnoea (OSA), which is highly involved in a severe COVID-19 development and its serious outcomes. Even though obese OSA patients had an increased pulmonary embolism (PE) risk, there is no enough evidence to support the interaction between obesity and OSA regarding PE development in the setting of COVID-19. Our patient is a 45-year-old obese male with COVID-19, who was admitted to the intensive care unit (ICU) with acute respiratory failure requiring high-flow nasal oxygenation. Clinical, laboratory and diagnostic findings pointed on severe COVID-19 form, complicated with PE. After recovery, the diagnosis of OSA was established. With this case, we wanted to alert the physicians on comorbidities, such as obesity and OSA, while those conditions, to some extent, may contribute to worse COVID-19 clinical presentation.

Abstract
This paper highlights the cardioprotective potential of sodium-glucose cotransporter 2 inhibitors (SLGT2i), as well as several most discussed mechanisms responsible for their cardioprotection. Cardiovascular diseases are considered a primary cause of death in nearly 80% of type 2 diabetes mellitus (T2DM) patients, with a 2-4-fold greater incidence of heart failure (HF) among diabetics. As novel hypoglycemics, SGLT2i showed exceptional cardiovascular benefits, reflected through robust reductions of cardiovascular mortality and hospitalization for HF in T2DM patients. Recently, those effects have been reported even in patients with HF and reduced ejection fraction irrespectively of diabetic status, suggesting that cardioprotective effects of SGLT2i are driven independently of their hypoglycemic actions. SGLT2i exerted hemodynamic and metabolic effects, partially driven by natriuresis and osmotic diuresis. However, those systemic effects are modest, and therefore cannot be completely related to the cardiac benefits of these agents in T2DM patients. Hence, increased circulating ketone levels during SGLT2i administration have brought out another hypothesis of a cardiac metabolic switch. Moreover, SGLT2i influence ion homeostasis and exert anti-inflammatory and antifibrotic effects. Their enviable influence on oxidative stress markers, as well as anti- and pro-apoptotic factors, have also been reported. However, since the main mechanistical contributor of their cardioprotection has not been elucidated yet, a joint action of systemic and molecular mechanisms has been suggested. In the light of ongoing trials evaluating the effects of SGLT2i in patients with HF and preserved ejection fraction, a new chapter of beneficial SGLT2i mechanisms is expected, which might resolve their main underlying action.

Role of CA125/CEA ratio and ultrasound parameters in identifying metastases to the ovaries in patients with multilocular and multilocular-solid ovarian masses. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2019; 53:116-123. [PMID: 29978587 DOI: 10.1002/uog.19174] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2018] [Revised: 06/21/2018] [Accepted: 07/01/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVES To investigate ultrasound features and the best cut-off value of the cancer antigen 125/carcinoembryonic antigen (CA125/CEA) ratio to discriminate ovarian metastases from benign and primary malignant ovarian neoplasms in two selected groups of morphological ovarian masses, namely multilocular masses with five or more locules and multilocular-solid masses. METHODS Patients with multilocular (five or more locules) or multilocular-solid ovarian masses, operated on within 3 months of ultrasound examination, and with tumor markers (CEA and CA125) available at diagnosis, were identified retrospectively from three ultrasound centers. The masses were described using the International Ovarian Tumor Analysis (IOTA) terminology. Ultrasound and clinical characteristics were compared between those with an ovarian neoplasm (including benign and primary malignant neoplasms) and those with an ovarian metastasis. Receiver-operating characteristics curve (ROC) analysis was used to evaluate the ability of CA125, CEA and CA125/CEA to differentiate between ovarian neoplasms and ovarian metastases, and their predictive performance was assessed. RESULTS In total, 350 (88.4%) patients with an ovarian neoplasm (including 99 benign, 43 borderline and 197 primary epithelial ovarian carcinomas, seven malignant rare tumors and four other types of invasive ovarian tumor) and 46 (11.6%) patients with an ovarian metastasis were analyzed. On ultrasound examination, ovarian neoplasms were smaller than ovarian metastases (median largest diameter, 97 (range, 20-387) mm vs 146 (range, 43-259) mm, respectively; P < 0.0001) and presented with a lower number of cysts with > 10 locules (18.9% vs 54.3%; P < 0.0001). ROC curve analysis showed that the best cut-off value of CEA for distinguishing between ovarian neoplasms and ovarian metastases was 2.33 ng/mL. The predictive performance of this CEA cut-off value was: area under the curve (AUC), 0.791 (95% CI, 0.711-0.870); accuracy, 73.7%; sensitivity, 73.1%; specificity, 78.3%; positive predictive value (PPV), 96.2%; and negative predictive value (NPV), 27.7%. The best cut-off value of CA125/CEA for distinguishing between ovarian neoplasms and ovarian metastases was 11.92. The predictive performance of this CA125/CEA cut-off value was: AUC, 0.758 (95% CI, 0.683-0.833); accuracy, 79.8%; sensitivity, 82.3%; specificity, 60.9%; PPV, 94.1%; and NPV, 31.1%. CONCLUSIONS CA125/CEA ratio and CEA alone did not show any significant difference in their ability to distinguish between ovarian neoplasms (including benign and malignant) and ovarian metastases in masses with multilocular and those with multilocular-solid morphology. Therefore, in this morphological subgroup of ovarian masses, CEA alone is sufficient to differentiate between ovarian neoplasms and ovarian metastases. Copyright © 2018 ISUOG.

Abstract
This research aimed to investigate factors associated with vitamin D deficiency and to provide data about its prevalence in patients suffering from different psychiatric illnesses. The study had a cross-sectional design and it included 220 patients of both genders, aged from 19-81 y, with a wide range of mental disorders (F00-F89), and treated in routine ambulatory and hospital practice. The researchers collected data from three sources: medical records, a study questionnaire and biochemical analysis of patients' serum samples (concentration of vitamin D measured as 25(OH)D, calcium, phosphorus, magnesium, sodium and potassium). Data were analyzed using descriptive statistics, methods for hypothesis testing and binary logistic regression, at the p≤0.05 level. A total of 140 patients (64%) had a deficiency of vitamin D (<12 ng/mL), and 45 (20%) had inadequate vitamin D serum levels (12-20 ng/mL), while 35 (16%) had sufficient vitamin D serum concentrations (>20 ng/mL). Among variables related to demographics, life style habits, mental illness, comorbid disorders and drugs, two of them, female gender (odds ratio (OR)=2.5, 95% confidence interval (CI)=1.3-4.9, p=0.006) and using clozapine (OR=15.6, 95% CI 1.7-144.7, p=0.02), were significantly associated with vitamin D deficiency. Physical activity (OR= 0.4, 95% CI 0.2-0.9, p=0.02), exercising (OR=0.2, 95% CI <0.1-0.7, p=0.02) and offal in the diet (OR=0.5, 95% CI 0.3-0.9, p=0.03) significantly aggregated in the patients who had a 25(OH)D serum concentration above the deficiency cut-off level. Patients with mental disorders are at high risk for vitamin D deficiency, particularly females and clozapine users as well as those having no adequate physical activity or dietary habits.

Abstract
OBJECTIVE Serum parameters of calcium homeostasis were measured based on previously published evidence linking osteoporotic fractures and/or bone/mineral loss with antipsychotics. METHODS Prospective, four-week, time-series trial was conducted and study population consisted of patients of both genders, aged 35-85 years, admitted within the routine practice, with acute psychotic symptoms, to whom an antipsychotic drug was either introduced or substituted. Serial measurements of serum calcium, phosphorous, magnesium, 25(OH)D, parathyroid hormone, calcitonin, osteocalcin and C-telopeptide were made from patient venous blood samples. RESULTS Calcium serum concentrations significantly decreased from baseline to the fourth week (2.42±0.12 vs. 2.33±0.16 mmol/L, p=0.022, n=25). The mean of all calcemia changes from the baseline was -2.6±5.7% (-24.1 to 7.7) with more decreases than increases (78 vs. 49, p=0.010) and more patents having negative sum of calcemia changes from baseline (n=28) than positive ones (n=10) (p=0.004). There were simultaneous falls of calcium and magnesium from baseline (63/15 vs. 23/26, p<0.001; OR=4.75, 95% CI 2.14-10.51), phosphorous (45/33 vs. 9/40, p<0.001; 6.06, 2.59-14.20) and 25(OH)D concentrations (57/21 vs. 13/35, p<0.001; 7.31, 3.25-16.42), respectively. Calcemia positively correlated with magnesemia, phosphatemia and 25(OH)D values. Parathyroid hormone and C-telopeptide showed only subtle oscillations of their absolute concentrations or changes from baseline; calcitonin and osteocalcin did not change. Adjustment of final calcemia trend (depletion/accumulation) for relevant risk factors, generally, did not change the results. CONCLUSION In patients with psychotic disorders and several risks for bone metabolism disturbances antipsychotic treatment was associated with the decrease of calcemia and changes in levels of the associated ions.

Abstract
Introduction. Suicide attempts are a significant public health problem. They
are associated with significant morbidity and result in significant use of
health care resources. Objective. The aim of our study was to analyze
epidemiological characteristics attempts of suicide for persons in the period
2001-2010 who were hospitalized at the Psychiatric Clinic in Kragujevac after
the attempt of suicide. Methods. We analysed 286 clinical records of patients
who had attempted suicide (133 males, 153 females). We used the illness
history of patients, who were treated at the Psychiatric Clinic in Kragujevac
after their suicide attempts. We made the analysis of socio-demographic
characteristics of the sample and characteristics of the suicide act itself.
Results. Our results showed a higher rate of female population, except for
the period 2003-2005: 2003 - 14 males (58.3%), 2004 - 15 (62.5%) and 2005 -
60%. The largest number of attempts was in the population aged between 25 and
34 years (23.8%). The percentage of persons from urban areas was higher
(66.4%). Depressive disorder was a common pre-existing disorder before a
suicide attempt (42.3%). Most attempts of suicide were performed by
overdosing on medications (57.7%). Conclusion. In the last three years we
observed a decrease of suicide attempts. We noticed that middle aged persons
are the most frequent ones to attempt suicide. Depressive disorder is the
most frequent pre-existing condition of suicide attempt. In order to prevent
suicide attempts we must improve early detection of depressive disorder, as
well as initial treatment.

Abstract
The results of the essential oil composition confirm that there are differences between populations within the same subspecies (Satureja montana ssp. montana, between the subspecies (Satureja montana ssp. montana and Satureja montana ssp. pisidica) and the species (Satureja montana and S. kitabelii). The essential oil composition of S. montana ssp. montana is more related to the Satureja montana ssp. pisidica than S. kitaibelii which separates as a whole species.
