A new protocol for renal collecting system sterilization with antibiotic irrigation during lithotripsy in retrograde intrarenal surgery: a prospective, comparative study.

PURPOSE: To present a new protocol using antibiotic irrigation during lithotripsy in retrograde intrarenal surgery (RIRS) to provide sterility of the renal collecting system. METHODS: This prospective study included 102 patients who underwent RIRS between January 2022 and August 2023. The patients were examined in two groups as those who received antibiotic irrigation (n:51) and standard irrigation (n:51). In the antibiotic irrigation group, 80 mg of gentamicin was dissolved in normal saline in a 3 L irrigation pouch to obtain a 26.7 mg/L concentration. In the standard irrigation group, normal saline was used. Preoperative information, including age, sex, body mass index (BMI), ASA score, stone side, volume, and density, and the Seoul National University Renal Stone Complexity (S-ReSC) score. The groups were compared with respect to postoperative fever (> 38 °C), urinary tract infection (UTI), systemic inflammatory response syndrome (SIRS), infectious complications such as sepsis, and stone-free rate. RESULTS: No statistically significant difference was determined between the groups with respect to age, sex, BMI, ASA score, stone side, volume and density, and S-ReSC score (p > 0.05 for all). Statistically significant differences were determined between the groups with respect to postoperative fever (p = 0.05), SIRS (p = 0.05), and hospital length of stay (p = 0.05). Sepsis was observed in one patient in the standard irrigation group and in none of the antibiotic irrigation group. CONCLUSION: The reliability, efficacy, and utility of antibiotic irrigation during lithotripsy in RIRS were presented in this study as a new protocol for sterilization of the renal collecting system which will be able to reduce infectious complications.

A new position utilizing the effect of gravity in proximal ureteral stones, ureteroscopic lithotripsy in the reverse Trendelenburg position: a prospective, randomized, comparative study.

PURPOSE: To evaluate the effect of the reverse Trendelenburg position in patients undergoing ureteroscopic lithotripsy for proximal ureteral stones. METHODS: The study included 167 patients who underwent ureteroscopic lithotripsy for proximal ureter stones between December 2020 and September 2022. The patients were randomly assigned to one of three groups: standard lithotomy (n:55), 10° reverse Trendelenburg (n:55), and 20° reverse Trendelenburg (n:57). Preoperative information, including age, sex, body mass index (BMI), previous shock wave lithotripsy (SWL), stone side, volume, and density, distance to the ureteropelvic junction (UPJ) of the stone, and hydronephrosis degree. Stone-free status was evaluated with computed tomography (CT) at 4 weeks postoperatively. The groups were compared in respect of stone migration, stone-free rate, use of flexible ureterorenoscope, operating time, postoperative length of stay in the hospital, and complications. RESULTS: No statistically significant difference was determined between the groups with respect to age, sex, BMI, previous SWL, stone side, volume and density, distance to the UPJ of the stone, and hydronephrosis degree (p > 0.05 for all). Statistically significant differences were determined between the groups with respect to stone migration (p = 0.001), stone-free rate (p < 0.001), use of flexible ureterorenoscope (p = 0.01), operating time (p < 0.001), hospital length of stay (p < 0.001), postoperative fever (p = 0.002), and total complications (p = 0.01). CONCLUSION: A new patient position is presented in this study, which can be used in ureteroscopic lithotripsy performed for proximal ureteral stones. The reverse Trendelenburg position constitutes a surgical method that can be used safely and successfully in the treatment of proximal ureteral stones. TRIAL REGISTRATION NUMBER: NCT04894058, 05/21/2021, Prospectively registered.

Optimal Dwelling Time for Ureteral Stents Placed for Passive Dilation after Impassable Ureteroscopy.

INTRODUCTION: The aim of the study was to determine the correlation between the dwelling time for a ureteral stent placed for passive dilation after impassable ureteroscopy and success and complications. METHODS: A retrospective evaluation was made of patients who underwent stent placement after impassable ureteroscopy and a repeat ureteroscopy due to kidney stones. A total of 161 patients were included in the study between 2015 and 2022. Demographic, clinical, preoperative, and perioperative data were collected. Logistic regression analyses were performed on the data showing a significant difference in the univariate analyses performed to determine the predictive factors of ureteroscopy after the stent dwelling period in terms of stone-free status and perioperative complications. RESULTS: Stone-free status was achieved in 110 (68.3%) of 161 patients, and perioperative complications were observed in 41 (25.4%). Factors that affected the stone-free status were determined as the dwelling time and the S-ReSC score, while factors affecting perioperative complications were the stent dwelling time and the operation time. The stone-free rates were observed to increase from 46.4% in the first 2 weeks to 72.9% after the 2nd week, an increase of 1.5-fold. Perioperative complications were determined at the rate of 17.5% during the first 5 weeks and increased 2.1-fold to 37.5% after the 5th week. CONCLUSION: It can be recommended that great care is taken during the stent dwelling period and ureteroscopy should be performed within 5 weeks (14-35 days) but no earlier than 2 weeks, so as not to affect the success of the procedure.

Safety and Efficacy of High-Powered Holmium Laser Enucleation of the Prostate within 1-3 Weeks Following Prostate Biopsy.

PURPOSE: We aim to document the feasibility, perioperative safety, and the 12-month efficacy of holmium laser enucleation of the prostate (HoLEP) within 1-3 weeks following transrectal ultrasound (TRUS)-guided prostate biopsy. METHODS: Data of the patients who underwent HoLEP following TRUS-guided prostate biopsy between March 2017 and July 2020 were analyzed retrospectively. Patients were divided into 2 groups: group 1 had undergone HoLEP in the early period after TRUS-guided prostate biopsy, while group 2 patients were biopsy-naive ("control group"). All patients were assessed preoperatively by a physical examination with the digital rectal examination; time from biopsy to HoLEP; measurement of Qmax, postvoiding residual volume, and prostate volume by transabdominal ultrasonography; serum prostate-specific antigen level, the International Prostate Symptom Score (IPSS); the International Index of Erectile Function-5 questionnaire; and urine analysis. The patients were reevaluated at 3- and 12-month follow-up. Perioperative and postoperative complications were documented according to the modified Clavien-Dindo System. RESULTS: Group 1 comprised 66 patients with a mean age of 67.3 ± 6.7 (range, 53-86) years, and group 2 comprised 114 patients with a mean age of 69.4 ± 9.4 (range, 36-95) years. The operation, enucleation, and morcellation efficiencies were not statistically significant between the groups. Preoperative Qmax and IPSS values were significantly improved after HoLEP surgery in the 3rd and 12th months in all patients. Our complication rates were similar in both groups. CONCLUSION: High-powered HoLEP using 140 W energy within 1-3 weeks following TRUS-guided prostate biopsy is a feasible procedure with high enucleation efficiency, low perioperative morbidity, and excellent functional outcomes. A recent TRUS-guided prostate biopsy is not a contraindication to HoLEP.

Holmium Laser Enucleation, Laparoscopic Simple Prostatectomy, or Open Prostatectomy: The Role of the Prostate Volume in terms of Operation Time.

INTRODUCTION: To compare the prostate removal speeds of 3 enucleation techniques and to evaluate how the operating times change depending on the prostate volume. METHODS: Medical records of patients with 80-g or larger prostates who underwent holmium laser enucleation of the prostate (HoLEP), laparoscopic simple prostatectomy (LSP), or open prostatectomy (OP) due to medical treatment-resistant benign prostatic hyperplasia (BPH) were reviewed retrospectively. Patients were classified into 3 groups according to the surgical procedure. Age, BMI, prostate weights, total operation times, prostate removal speeds, hospitalization and catheterization days, complications, and improvements on functional outcomes in the 3rd month of follow-up were compared between groups. In addition, the association between prostate weight and total operation time was analyzed for each group. RESULTS: HoLEP, LSP, and OP groups consisted of 60, 61, and 37 patients, respectively. While HoLEP was similar to OP in terms of prostate removal speed and total operation time, LSP was statistically slower and required more operation time than HoLEP and OP. There was a relationship between prostate weight and total operation time only in HoLEP. CONCLUSION: LSP, one of the enucleation techniques in the treatment of large prostates, was slower and required more operation time than HoLEP and OP in terms of total operation time and prostate removal speed. HoLEP seems going to be the fastest candidate for the rapid removal of large prostates in the future.

Osseointegrated Implants for Orbito-Facial Prostheses: Common Complications and Solutions.

PURPOSE: To evaluate anatomical and functional results of osseointegration with magnetic coupling for oculofacial prosthetic rehabilitation after exenteration. METHODS: This retrospective study included 11 consecutive patients who received orbital reconstruction and oculofacial prosthetic rehabilitation between September 2015 and October 2019. Patient demographics, surgical indications, previous treatment procedures, histopathologic features, and reconstructive procedures were recorded. RESULTS: The mean age was 37.81 ±â€Š23 years (range 5-78 years). The mean follow-up was 23.81 ±â€Š12 months (range 10-48 months). The principal diagnoses were squamous cell carcinoma of the eyelids (n = 2/11), mucoepidermoid carcinoma of the maxillary sinus (n = 2/11), rhabdomyosarcoma (n = 1/11), mucormycosis (n = 1/11), neurofibromatosis (n = 1/11), basosquamous carcinoma (n = 1/11), malign melanoma (n = 1/11), primitive neuroectodermal tumor (n = 1/11), and retinoblastoma (n = 1/11). Six of the patients were repaired by primary closure. Procedures performed to reconstruct the orbital cavity included split-thickness skin graft (n = 2/11), temporalis muscle flap (n = 2/11), and frontalis muscle flap (n = 1/11). Nine of the 11 patients who received orbital implants were successfully rehabilitated by epithesis. Postoperative complications included implant loss (n = 4/11), periprosthetic local infection (n = 3/11), and soft tissue overgrowth around the orbital prosthesis (n = 2/11). All patients had Straumann bone level implant (Basel, Switzerland) osseointegrated titanium implants (3.5 mm) placed in a 2-stage procedure over a span of 3 to 4 months with subsequent successful prosthesis fitting. CONCLUSION: The reconstructive methods following orbital exenteration, should be customized according to the patients' characteristics such as extension of the orbital defect, bone quality, and expectations to achieve satisfactory results.

Evaluation of Lacrimal Drainage Function in the Anophthalmic Socket by Dacryoscintigraphy.

PURPOSE: To investigate whether impaired lacrimal pump function is a possible cause of discharge in patients wearing an artificial eye compared with the remaining healthy eye. METHODS: Consecutive patients wearing unilateral ocular prosthesis for ≥6 months were included in this retrospective study. Excluded were any deformities of eyelids or nasal passage, socket complications such as entropion, ectropion, ptosis, infection, pyogenic granuloma, contracted socket, obstruction of nasolacrimal duct diagnosed with lacrimal irrigation and a difference greater than 2 mm in terms of protrusion between two eyes detected by Hertel exophthalmometry. Patients were asked to score the levels of tearing and mucopurulent discharge between 0 and 5 to assess lacrimal drainage function subjectively. Furthermore, dacryoscintigraphy was performed to assess the functional status of the lacrimal system objectively. RESULTS: Included were 32 subjects (12 females, 20 males; aged 32.94 ±â€Š17.62, range 13-78). Mean duration of prosthetic wearing 26.41 ±â€Š21.30 (6-72) months. The mean subjective scores of tearing and mucopurulent discharge were 1.56 ±â€Š1.67 and 1.94 ±â€Š1.63, respectively. The rate of functional stenosis was significantly higher in the anophthalmic socket side as compared to the healthy side (P = 0.002). The rates of a presac, preduct, and intraduct obstruction was notes as n = 9, n = 10, n = 1 and n = 0, n = 6, n = 2 in the anophthalmic side and the companion eye, respectively (P = 0.021). CONCLUSION: Compared to paired healthy eyes, the ocular prosthesis exhibited significantly higher rates of functional lacrimal duct obstruction, especially at the presac level. The alterations in orbital volume and tear film composition in addition to reduced corneal reflex blinking may lead to the failure of lacrimal pump function in artificial eyes.

Comparison of Three Different Techniques on the Movement of Implants After Evisceration.

PURPOSE: To compare the results of 3 evisceration techniques involving placement of an acrylic implant within the scleral shell without posterior sclerotomy (Group 1), posterior sclerotomy with placement of a porous implant within the intraconal space (Group 2) and posterior sclerotomy with placement of a acrylic implant within the intraconal space (Group 3) with respect to ocular mobility, implant complications and patient satisfaction. METHODS: Single-center, retrospective, interventional case series. A chart review of 72 patients undergoing evisceration between February 2013 and January 2018 was carried out. Thirty-five patients met the inclusion criteria having a normal or near normal size eye and at least 6 months follow-up. The horizontal movements of the implant and the artificial eye was measured by using a ruler. Data analyses were conducted using the Mann-Whitney U test for 2 independent samples. RESULTS: Neither infection nor prolapse of the implant had occurred in any of the patients. The mean implant sizes were 18 mm in Group 1, 20 mm in Group 2 and 20 mm in Group 3. Statistically, a significant difference was assessed between Group 1 and Group 2 in both nasal and temporal movement of the socket; nasal and temporal movement of the prosthesis. Statistically, a significant difference was assessed between Group 1 and Group 3 in both nasal and temporal movement of the socket; nasal and temporal movement of the prosthesis. However, there was no statistically significant difference between Group 2 and Group 3 in neither nasal and temporal movement of the socket nor nasal and temporal movement of the artificial eye. CONCLUSION: Group 1 showed the significantly better movement of both prosthesis and socket in adduction and abduction than Group 2 and 3. The likely explanation for this may be that preserving the scleral shell integrity allows more efficient transmission of muscle contraction to the socket and prosthesis.

The efficiency of inspiratory muscle training in patients with ankylosing spondylitis.

Ankylosing spondylitis (AS) is an inflammatory rheumatic disease affecting mainly the axial skeleton and sacroiliac joints. The aim of the current study was to investigate the effects of inspiratory muscle training (IMT) on respiratory muscles and functional exercise capacity, as well as on the specific outcomes of the disease in AS patients. A total of 32 AS patients (mean age 37.37 ± 10.41 years) were randomly assigned as the Training Group (TG) (n = 16, mean age = 35.62 ± 8.18 years) who received IMT + conventional exercise, and the Control Group (CG) (n = 16, mean age = 39.12 ± 12.26 years) who only performed the conventional exercise program. All the subjects were evaluated at baseline and at the end of the 8th week. Respiratory muscle strength was assessed by measuring the maximal inspiratory pressure (PImax) and maximal expiratory pressure (PEmax). Functional exercise capacity was measured using the 6-min walk test (6MWT). The Bath AS Disease Activity Index (BASDAI), Bath AS Disease Function Index and Bath AS Metrology Index were used for activity, function and basic measurements of the disease. A statistically significant improvement was determined in the PImax (p = 0.000), PEmax (p = 0.002), 6MWT (p = 0.041) and BASDAI (p = 0.049) values in the TG after training. There was a significant difference between baseline and after conventional exercise in terms of PEmax (p = 0.017) in the CG. The PEmax (p = 0.001) and the 6MWT (p = 0.053) values were significantly better in the TG. The results of this study demonstrated that IMT in addition to conventional exercises increased inspiratory muscle strength, functional exercise capacity and positively affected the disease activity in AS.

Feeling safe in the plane: neural mechanisms underlying superior action control in airplane pilot trainees--a combined EEG/MRS study.

In day-to-day life, we need to apply strategies to cascade different actions for efficient unfolding of behavior. While deficits in action cascading are examined extensively, almost nothing is known about the neuronal mechanisms mediating superior performance above the normal level. To examine this question, we investigate action control in airplane pilot trainees. We use a stop-change paradigm that is able to estimate the efficiency of action cascading on the basis of mathematical constraints. Behavioral and EEG data is analyzed along these constraints and integrated with neurochemical data obtained using Magnetic Resonance Spectroscopy (MRS) from the striatal gamma-aminobutyric acid (GABA) -ergic system. We show that high performance in action cascading, as exemplified in airplane pilot trainees, can be driven by intensified attentional processes, circumventing response selection processes. The results indicate that the efficiency of action cascading and hence the speed of responding as well as attentional gating functions are modulated by striatal GABA and Glutamate + Glutamine concentrations. In superior performance in action cascading similar increases in the concentrations of GABA and Glutamate + Glutamine lead to stronger neurophysiological and behavioral effects as compared to subjects with normal performance in action cascading.

Comparison of Medpor coated tear drainage tube versus silicon tear drainage tube in conjunctivodacryocystorhinostomy: problems and solutions.

PURPOSE: This study aims at comparing two different types of drainage tubes in conjunctivodacryocystorhinostomy, which are used for upper lacrimal system obstruction or damage, with respect to their respective postoperative problems and solutions. METHODS: Nineteen eyes of 17 patients who underwent conjunctivodacryocystorhinostomy (CDCR) or conjunctivorhinostomy (CR) surgery with a Medpor coated tear drainage tube or silicon tube placement between October, 2010, and February, 2014, were included in this retrospective comparative study. RESULTS: In the initial surgery, Medpor coated tear drainage tubes were used in 11 eyes by CDCR, whereas silicon tear drainage tubes were implanted into 2 eyes by CR and 6 eyes by CDCR. In group 1, proximal and distal obstructions developed postoperatively in 4 eyes, while 1 eye showed tube malposition and 3 eyes developed luminal obstruction by debris 3 times. In group 2, tube extrusion developed in 4 eyes, whereas tube malposition developed in 6 eyes and luminal obstruction by debris developed in 6 eyes at different times, for a total of 20 times. CONCLUSIONS: In our study, the most significant complication we observed in the use of silicon tear drainage tubes was tube extrusion,whereas the leading complication related to the use of Medpor coated tear drainage tubes was tube obstruction.

How has the COVID-19 pandemic changed treatment preferences of patients with proximal ureteral stones?

Background: The impact of the coronavirus disease 2019 (COVID-19) pandemic on patient decision making remains uncertain. This study aimed to investigate the effect of the pandemic on treatment preferences of patients with proximal ureteral stones. Materials and methods: Retrospective data regarding treatment preferences of patients diagnosed with symptomatic proximal ureteral stones between July 2018 and November 2021 at a single center were analyzed. Data from 493 patients were analyzed according to 2 groups, including patients diagnosed during the COVID-19 pandemic and those diagnosed during an equivalent period of time before the pandemic. Results: Preference for conservative treatment increased during the COVID-19 pandemic (p = 0.009). In patients who had previously undergone shock wave lithotripsy (SWL), the preference for SWL decreased and the preference for conservative treatment increased during the COVID-19 pandemic (p = 0.042). Multiple logistic regression analysis revealed a significant correlation between a preference for conservative treatment during the pandemic and no prior spontaneous stone passage (p = 0.003; odds ratio [OR], 2.48; 95% confidence interval [CI], 1.45-4.23), no hydronephrosis (p = 0.035; OR, 3.57; 95% CI, 1.34-9.49), and a visual analog scale score of 4 or less (p = 0.018; OR, 1.97; 95% CI, 1.15-3.38). Conclusions: A significant increase in the preference for conservative treatment was observed among patients diagnosed during the pandemic, and patients with a history of SWL demonstrated a preference shift from SWL to conservative treatment.

Aortic distensibility and aortic intima-media thickness in patients without clinical manifestation of atherosclerotic cardiovascular disease.

BACKGROUND: There is growing evidence that aortic distensibility (AD) is a subclinical marker of early atherosclerosis. Aortic intima-media thickness (IMT) was an earlier marker than carotid IMT of preclinical atherosclerosis. In this study, we aimed to assess the relationship between thoracic aortic IMT and AD. METHODS: We studied 192 patients (mean age: 45.5 ± 8.4 years) who underwent transesophageal echocardiography (TEE) for various indications. Four different grades were determined according to IMT of thoracic aorta (Grade 1 < 1 mm; 1 mm ≤ Grade 2 < 3 mm; 3 mm ≤ Grade 3 < 5 mm; 5 mm ≤ Grade 4). AD was calculated from the echocardiographically derived ascending aorta diameters and hemodynamic pressure measurements in all patients. High sensitive C-reactive protein (hsCRP) and other biochemical markers were measured using an automated chemistry analyzer. RESULTS: TEE evaluation characterized thoracic aortic intimal morphology as grade 1 in 71 patients (37%), grade 2 in 57 patients (29.7%), grade 3 in 34 patients (17.7%), and grade 4 in 30 (15.6%) patients. The lowest AD level was observed in grade 4 group compared with grade 1 and grade 2 groups (P < 0.001, P = 0.009, respectively). AD level of grade 3 group was lower than grade 1 and grade 2 group (P < 0.001, P = 0.021, respectively). In multiple linear regression analysis, AD was independently associated with age (ß = -0.138, P = 0.029), hsCRP (ß = -0.209, P = 0.001), and aortic IMT (ß = -0.432, P < 0.001). CONCLUSION: AD is independently associated with age, thoracic aortic IMT, and hsCRP. Impaired elasticity index of the aorta might be an independent predictor for the severity of thoracic atherosclerosis.

Predictors of preinterventional patency of infarct-related artery in patients with ST-segment elevation myocardial infarction: Importance of neutrophil to lymphocyte ratio and uric acid level.

BACKGROUND: Patients with ST-segment elevation myocardial infarction (STEMI) and a patent infarct-related artery (IRA) experience lower mortality and better clinical outcome, but little is known about the predictors of IRA patency before primary percutaneous coronary intervention (PCI) in the setting of STEMI. OBJECTIVE: To assess possible predictors of patency of IRA before primary PCI in patients with STEMI. METHODS: A total of 880 patients with STEMI undergoing primary PCI were prospectively included (646 male, 234 female; mean [± SD] age 58.5±12.4 years). Blood samples were obtained on admission to investigate biochemical markers. Preinterventional thrombolysis in myocardial infarction (TIMI) flow was assessed in all patients. The patients were divided into two groups according to the pre-PCI TIMI flow as impaired flow group (TIMI flow 0, 1 and 2) and normal flow group (TIMI flow 3). Transthoracic echocardiography was performed in all patients. RESULTS: Eighty-three (9.43%) patients had pre-PCI TIMI 3 flow in IRA. Uric acid levels and neutrophil to lymphocyte (N to L) ratio in the normal flow group were lower than in the impaired flow group (P<0.001 for both). However, ejection fraction (EF) was higher in the normal flow group than in the impaired flow group. Multivariate logistic regression analysis showed that IRA patency was independently associated with serum uric acid level (ß 0.673 [95% CI 0.548 to 0.826]; P<0.001), N to L ratio (ß 0.783 [95% CI 0.683 to 0.897]; P<0.001) and EF (ß 1.033 [95% CI 1.006 to 1.061]; P=0.016). CONCLUSION: Serum uric acid level, N to L ratio and EF are independent predictors of the pre-PCI patency of IRA in patients with STEMI undergoing primary PCI.

[Psychiatric evaluation in patients with obstructive sleep apnea syndrome]. / Obstrüktif uyku apne sendromlu hastalarin psikiyatrik açidan degerlendirilmesi.

INTRODUCTION: Obstructive sleep apnea syndrome (OSAS) might cause neuropsychiatric problems as well as cardiovascular and cerebrovascular complications. Daily life of the patients are effected and their quality of life decreases. In the present study, we aimed to evaluate anxiety and depression and to test their ability to cope with strees in patients with OSAS. MATERIALS AND METHODS: The patients with OSAS suspect admitting to our sleep laboratuary, were classed as simple snoring, mild-moderate and severe OSAS according to their apnea-hypopnea index (AHI). Hospital anxiety and depression, stres coping and skill loss scales were applied to the patients accepted to participate to the study. RESULTS: Fifty four patients participated into the study. Forty-one (75.9%) were OSAS and 13 (24.1%) were simple snoring (control group). Mean age was 52.3 ± 9.2 years in OSAS group, while it was 50.5 ± 9.9 years in control group. Snoring was found in every patient of two groups. Thirty-one (79.5%) patients with OSAS had witnessed apneas and 23 (60.5%) had exceesive OSAS patients had excessive daytime sleepiness. There was no significant differences in age, BMI, sleep efficency, HAD and skill loss scales between both groups. Autism was found higher in OSAS group with stres coping test (p= 0.031). Moreover, social support necessicity was found higher in moderate and severe OSAS patients. CONCLUSION: We found that neuropsyhiatric problems are highly seen in moderate and severe OUAS patients.

Update on occupational health nursing through 21st century requirements: A three-round Delphi study.

BACKGROUND: Occupational health nurses have promoted health and practiced at a strategic level for many years, and are closely aligned with public health and policies, workplace and environmental regulations, and changes in the nursing profession. OBJECTIVE: This study was carried out to create a consensus text on the definition, qualifications, responsibilities, and education of occupational health nurses based on the 21st century requirements. DESIGN AND METHODS: A Delphi panel of public health nursing academicians, occupational health nurses, other health professionals, faculty members of public health, and occupational physicians. A consensus-building approach using three rounds of e-Delphi technique were used, with 45 participants in the first round, 41 in the second round, and 36 in the third round. Data were collected in all three rounds with Google Forms between October 28, 2021, to February 28, 2022. Qualitative content analysis was performed in the first round, and mean, standard deviation, median, and mode values were presented based on the answers to the 5-point Likert questions in the second and third rounds. Values of at least 80 % and above were used for the consensus text in the third round. RESULTS: 62.2 % of the participants were female. The mean age was found 47.71 ± 11.03 years. The experts reached a consensus on the definition of occupational health nurse by emphasizing professionalism, effective communication, record keeping, nursing knowledge, skills, equipment, and competence in the field, with a participation of 91.7 %. A consensus was reached on the qualifications including observation, examination, evaluation, research, health promotion, compliance with confidentiality and ethical rules, and working in harmony with the team, with a participation of 94.4 %. The responsibilities of occupational health nurses included to create a healthy and safe workplace, participate in periodic health examinations, maintain effective communication with employees, acting in accordance with ethical principles, provide continuous professional development, and perform health education and promotion, guidance, and counseling. Experts specified that occupational injuries and diseases, duties, authorities, and responsibilities of the occupational health nurse, occupational health and safety legislation, health education, risk assessment, effective communication, and health literacy need to be integrated into the content of certificate program with 97.7 % participation. A maximum of 500 h for the total duration of the certificate training was suggested. CONCLUSIONS: The expert panel opinions provide a wide perspective for competencies, and educational standards of occupational health nurses. The results could assist in initiating the infrastructure of multidisciplinary postgraduate education programs, developing national and international collaborations, and increasing the number of scientific events should contribute to the professional development of occupational health nursing. Future research should focus on imbedding these consensus items in national and international certificate programs to prepare qualified advanced occupational health nurses.

Perspective of Workers' Union Representatives on COVID-19 Measures in Turkish Workplaces in the First Year of the Pandemic

Background: Severe acute respiratory syndrome coronavirus-2, the virus causing coronavirus disease-2019, is a biological hazard in workplaces. Thus, protective measures should be applied. Despite their potential role, the perspective of workplace representatives on coronavirus disease-2019 measures is rarely investigated. Aims: To assess the perspective of workplace union representatives on coronavirus disease-2019 measures in their workplaces in the first year of the pandemic in Turkey. Study Design: A descriptive observational study. Methods: This national descriptive study included workplace chief representatives of 33 workers' unions. A 42-item electronic survey was used to collect data to evaluate the practice of job organization, social distancing and personal protective equipment use, sanitization, and occupational safety and health training. Results: The study included 509 workplace chief representatives' responses. Results showed that several administrative measures, including suspending production or work, encouraging workers to take leave, implementing alternate work schedules, isolating any coronavirus disease-2019 case from other workers in a designated room, and avoiding face-to-face meetings, were not available in more than half of the workplaces. The mean number of available measures was significantly high (p < 0.001) in the industrial sector and workplaces with 250 or more workers. Almost all union representatives (98.8%) reported at least one diagnosis of coronavirus disease-2019 among workers, and 12.6% reported a positive history of coronavirus disease-2019-related mortality. The regression model for any history of coronavirus disease-2019 mortality in workers demonstrated a significantly increased association with workplaces with 250 or more workers compared with workplaces with less than 250 workers (odds ratio =2.99, 95% confidence interval =1.65-5.44, p < 0.001). Conclusion: The results indicate failure in administrative measures and the need for improvement in medium- and small-sized workplaces and the non-industrial sector. All local and national stakeholders need to pay special attention to address these issues. Future studies should evaluate on-site coronavirus disease-2019 workplace measures and their effectiveness.

Comparison of Posterior and Antero-Lateral Renal Tumors in Retroperitoneal Laparoscopic Partial Nephrectomy: A Propensity Score Matching Analysis.

This study aimed to compare the antero-lateral and posterior localized renal masses in laparoscopic partial nephrectomy with the retroperitoneal approach in terms of operative, functional, and oncological outcomes. Patients who underwent retroperitoneal laparoscopic partial nephrectomy by a single surgeon between January 2013 and January 2021 were included in the study. A one-to-one propensity score matching (PSM) analysis was conducted to obtain two balanced groups. The patients were divided into two groups as posterior and antero-lateral according to the localization of the mass. A total of 239 patients were included in the PSM analysis, with 65 patients allocated to each group. The mean operative time was 79.2 ± 11.2 min in the posterior group, while it was 90.0 ± 11.6 min in the antero-lateral group (P < 0.001). Warm ischemia time was 15.9 ± 2.4 min in the posterior group and 18.6 ± 2.7 min in the antero-lateral group (P < 0.001). The median decrease in eGFR at 1 year was 4.8 (IQR, 2.9-6.9) mL/min in the posterior group and 5.0 (IQR, 2.8-11) mL/min in the antero-lateral group (P = 0.219). The warm ischemia time and clamping technique were found to be significant factors for predicting eGFR change after surgery (ß:0.693, 95% CI: 0.39-0.99, P < 0.001; ß:6.43, 95% CI: 1.1-11.7, P = 0.017, respectively). We report that retroperitoneal laparoscopic partial nephrectomy provided longer warm -ischemia and operative time for antero-lateral renal masses than posterior masses. However, long-term oncological and functional results were similar for both localizations.

Predictive factors affecting morcellation efficiency in holmium laser enucleation of the prostate.

PURPOSE: To determine the factors affecting morcellation efficiency in holmium laser enucleation of the prostate (HoLEP) surgery. MATERIALS AND METHODS: Patients who underwent HoLEP surgery by a single surgeon between 2018 and 2022 were included in the study. Our primary outcome of interest in this study was morcellation efficiency. The effect of preoperative and perioperative variables on morcellation efficiency was evaluated with linear regression analysis. RESULTS: A total of 410 patients were included in the study. The mean morcellation efficiency was 6.95±1.70 g/min. Univariable and multivariable linear regression analysis was performed to identify factors affecting morcellation efficiency. Presence of the "beach ball" effect (small, round prostatic tissue fragments that are fibrotic and difficult to morcellate), the learning curve, resectoscope sheath type, prostate-specific antigen (PSA) density, morcellated tissue weight, and the presence of prostate calcification were found to be independent predictive factors (ß=-1.107, 95% CI: -1.59 to -0.55, p<0.001; ß=-0.514, 95% CI: -0.85 to -0.17, p=0.003; ß=-0.394, 95% CI: -0.65 to -0.13, p=0.003; ß=-0.302, 95% CI: -0.59 to -0.09, p=0.043; ß=0.062, 95% CI: 0.05 to 0.06, p<0.001; ß=-0.329, 95% CI: -0.55 to -0.10, p=0.004; respectively). CONCLUSIONS: This study reports that presence of the beach ball effect, the learning curve, small resectoscope sheath, PSA density, and presence of prostate calcification negatively affect morcellation efficiency. On the contrary, morcellated tissue weight has a linear relationship with morcellation efficiency.
