Nurses' level of sleepiness during night shift

AIMS

This study aimed to determine the peak hours of sleepiness and the factors affecting the sleepiness levels of nurses.

BACKGROUND

Sleepiness is commonly seen in individuals working night shifts. However, in case of nurses, this sleepiness can be a major threat to patient and staff safety.

METHOD

This was a prospective cross-sectional study. Data were collected between July and September 2023, and a stratified sampling method was used according to the departments in which the nurses worked. Data were collected using the Personal Information Form and Visual Analog Scale. Nurses reported their sleepiness levels at the beginning of each hour between midnight and 8:00 am.

EQUATOR CHECKLIST

The study adhered to the STROBE checklist for reporting.

RESULTS

The mean sleepiness levels of emergency department nurses, intensive care nurses, internal or surgical clinic nurses, and all nurses were 59.75 ± 15.50, 43.53 ± 20.49, 44.67 ± 18.88, and 49.15 ± 19.67, respectively. The highest sleepiness level of the nurses was at 05:00 am. A significant correlation was found between the variables of age, gender, marital status, sleep quality, number of patients cared, working style and satisfaction with working in the department, and sleepiness level (P < 0.05).

CONCLUSION

Nurses working night shifts experience sleepiness (highest at 5:00 am). In addition, the sleepiness levels of nurses are affected by some personal and clinical factors.

IMPLICATIONS FOR NURSING AND NURSING POLICY

Based on the results, there is a need for necessary policies regarding nurses' working hours and working conditions. To protect patient and employee safety, necessary strategies should be devised regarding the hours when nurses experience the highest sleepiness and the factors affecting sleepiness levels.

Analysis of orthostatic intolerance symptoms in patients with premature ejaculation

OBJECTIVE

The autonomic nervous system (ANS) plays an important role in maintaining physiological regulation. It regulates the body's response to many variable situations. Orthostatic intolerance (OI) is one of the most important signs of autonomic dysfunction. Autonomic dysfunction is known to cause premature ejaculation (PE) by disturbing the balance in erection and ejaculation cycles. Considering that OI may develop due to autonomic dysfunction in patients with PE, we hypothesized that OI symptoms would increase in these patients. The aim of our study was to investigate the relationship between orthostatic intolerance and PE.

PATIENTS AND METHODS

This case-control study included a total of 39 patients with PE and 47 volunteers without PE. All subjects were assessed using the self-reported Orthostatic Grading Scale (OGS). In addition, the validated five-item Turkish version of the Premature Ejaculation Diagnostic Tool (PEDT) was used to evaluate PE. The PE group included patients with a PEDT score ≥ 11.

RESULTS

The mean ages of the PE and control groups were 38.2 ± 7.8 and 40.5 ± 9.1 years, respectively (p = 0.137). The mean PEDT scores of the PE and control groups were 13.9 ± 3.6 and 6.6 ± 2.9, respectively (p < 0.0001), and their mean OGS scores were 5.6 ± 2.4 and 1.6 ± 1.3, respectively (p < 0.0001). A statistically significant correlation was found between the PEDT and OGS scores (r: 0.686, p < 0.0001).

CONCLUSIONS

The orthostatic intolerance symptoms of patients with PE were higher than those of the control group. There was a correlation between the severity of PE and the severity of orthostatic intolerance. This is the first study in the literature to reveal a relationship between orthostatic intolerance and PE.

The association between ureteral wall thickness and need for additional procedures after primary ureteroscopy in patients with ureteral stones above the iliac crest

PURPOSE

To examine the parameters affecting the need for additional procedures in the primary ureteroscopy treatment in patients with ureteral stones above the iliac crest level.

METHODS

Seventy-one patients were included in the study who were ≥ 18 years old and had undergone ureteroscopy (URS) for ureteral stones above the iliac crest level between 2018-2020 and had a non-contrast-enhanced abdominal computed tomography before the procedures were included in the study. Patients and stone characteristics were prospectively collected. The results were evaluated six weeks after URS. The absence of any residual fragment was thought to indicate stone-free status. The patients with failure were referred for the additional procedures.

RESULTS

The median patient age was 51 years [interquartile range (IQR): 18-66]. The median transverse stone diameter was 9.5 mm (IQR: 7.1-11.4), and the median ureteral wall thickness (UWT) was 5.8 mm (IQR: 4.3-6.5). In the univariate analysis, UWT (p < 0.001), presence of multiple stones (p = 0.008), and stone length (p = 0.022) affected stone-free status. The multivariate analysis revealed UWT as the only independent factor affecting the need for additional procedures after URS (p = 0.028). In the receiver operating characteristic curve analysis, the best threshold value for UWT according to the outcomes was identified as 5.8 mm.

CONCLUSION

Ureteral wall thickness was the only independent parameter determining the need for additional procedures and affecting the treatment outcomes after the URS procedure.

In-vivo or in-vitro stone attenuation: what is more valuable for the prediction of renal stone composition in non-contrast-enhanced abdominal computed tomography?

OBJECTIVES

To compare the efficacy of in-vivo and in-vitro stone attenuation in the prediction of stone composition using non-contrast-enhanced abdominal computed tomography (NCCT).

METHODS

This study included a total of 104 patients with renal stones who received percutaneous nephrolithotomy treatment for renal stones between December 2016 and December 2019 and underwent NCCT before the procedure. Preoperative (in-vivo) and postoperative (in-vitro) kidney stone attenuations were compared using the NCCT images of the patients. Renal stone fragments were analysed with the infrared spectrophotometer method.

RESULTS

The mean age of the 104 patients was 49.5 (interquartile range: 37-61) years. According to the receiver operating characteristics analysis, the cut-off values for the prediction of uric acid stones were determined to be 556 HU for the in-vivo and 774 HU for the in-vitro attenuation measurement. Sensitivity and specificity were 100% and 96.6%, respectively, for the in-vivo and 90.9 and 91%, respectively, for the in-vitro images. The cut-off values for the prediction of calcium stones were determined to be 824 HU and 1065 HU for the in-vivo and in-vitro attenuation measurements, respectively. Sensitivity and specificity were 97.3 and 96% for the in-vivo and 96 and 96% for the in-vitro images.

CONCLUSIONS

In-vivo stone attenuation measurement in NCCT was slightly superior to in-vitro measurement due to the reduction in the composition and size of the stone. Our findings show that NCCT in-vivo stone attenuation might differentiate uric acid and calcium stones from the other stone types.

Possible Clinical Benefits of Cardio-Ankle Vascular Index Measurement in Urological Diseases

Many factors are considered to affect vascular physiology. It is known that one of the reasons for many diseases is a pathology at the microvascular level. Therefore, the relationship between endothelial dysfunction and many diseases is currently being investigated. The clinical evaluations of arterial stiffness have made it possible to perform necessary risk assessment regarding cardiovascular diseases. In this way, protective measures can be taken against microvascular pathologies in many organs. In this paper, we present a review of studies investigating the relationship between urological conditions and the cardio-ankle vascular index (CAVI), a marker of arterial stiffness. As with erectile dysfunction, some studies have shown that conditions such as lower urinary tract symptoms, overactive bladder, and chronic kidney disease are also associated with an elevated CAVI. The association of erectile dysfunction and chronic kidney disease with vascular pathologies has been clearly demonstrated. In addition, lower urinary tract symptoms may be the first sign of silent vascular dysfunction. Assessing arterial stiffness with CAVI can help prevent future cardiovascular events in these patients.

Evaluation of endothelial dysfunction with cardio-ankle vascular index measurements in patients with erectile dysfunction

BACKGROUND

It has been reported that there is a relationship between erectile dysfunction (ED) and endothelial dysfunction. However, a practical and non-invasive method to clinically evaluate this relationship has not yet been determined. The cardio-ankle vascular index (CAVI) is a marker of arteriosclerosis that develops as a result of endothelial dysfunction.

OBJECTIVE

To investigate the correlation between CAVI and the presence and severity of ED.

MATERIALS/METHODS

This was a case-control study including 74 patients that presented to the urology department of our institution with ED (without cardiovascular risk factors) and 86 healthy individuals of similar age. The patients with ED and the control group were evaluated using the five-item version of the International Index of Erectile Function (IIEF-5). CAVI and ankle-brachial pressure index measurements were performed using the VaSera VS-1000 (Fukuda-Denshi Company, Ltd, Tokyo, Japan) device.

RESULTS

The mean age was 59.8±1.3 years for the ED group and 57.9±1.1 years for the control group. The mean right (R)-CAVI values of the ED and control groups were 9.20±2.6 and 8.11±1.8, respectively (p = 0.014), and their mean left (L)-CAVI values were 9.08±2.7 and 7.96±1.2, respectively (p = 0.008). The mean IIEF-5 score of the patients with ED was 10.1±3.6. An inverse correlation was found between R-CAVI and L-CAVI and the IIEF-5 score (r = -0.411, p = 0.011 and r = -0.454, p<0.001, respectively).

DISCUSSION AND CONCLUSION

According to our findings, CAVI was higher in patients with ED than in healthy individuals. This article is protected by copyright. All rights reserved.

Penile fracture: Tertiary care center experience and long-term complications after immediate repair

BACKGROUND

In the literature, there is not sufficient data on factors affecting the development of complications in patients with penile fracture after early surgical intervention.

OBJECTIVES

To investigate the predictors of long-term complications in patients who underwent immediate surgical repair for penile fracture.

MATERIALS/METHODS

This clinical study included a total of 31 cases of penile fracture in which surgical treatment was performed within the first 24 hours and penile fracture was confirmed during the operation. The patients with and without late complications were compared in terms of parameters such as age, tear size of the tunica albuginea of the penis, bilateral involvement of the corpora cavernosa involvement, urethral injuries, and duration from penile fracture to surgery.

RESULTS

The median age of the patients was 42 (interquartile range [IQR]: 34-51) years. The median time from penile fracture to surgery was 13 (8-18) hours. The median tear size was 16 (11-21) mm. Late complications were seen in 13 (41.9%) patients in the postoperative period. Erectile dysfunction (ED) developed in five (16.1%) patients in the postoperative period. There was no statistically significant relationship between age, tear size, time from penile fracture to surgery, and bilateral corporeal involvement in terms of ED development. Painful erections, penile deviations, urethral strictures, tunical scars, and re-fracture were the other late complications. There was a significant relationship between the development of any complication and time from penile fracture to surgery (p = 0.028) and tear size (p = 0.031). In the receiver operating characteristic analysis of complication development, the cut-off value for the time from penile fracture to surgery was 13.5 hours.

DISCUSSION AND CONCLUSION

We found that the longer time interval between penile fracture and surgery worsened the patient outcomes. In addition, tear size was determined to be a predictor for long-term complications. In our opinion, early treatment of penile fracture can prevent severe complications in these cases. This article is protected by copyright. All rights reserved.

Ureteral wall thickness is an independent parameter affecting the success of extracorporeal shock wave lithotripsy treatment in ureteral stones above the iliac crest

BACKGROUND

To investigate the relationship between ureteral wall thickness (UWT) and other variables of patients who underwent extracorporeal shock wave lithotripsy (SWL) in the primary treatment of the ureteral stone above the iliac crest level.

MATERIAL AND METHODS

A total of 147 patients aged 18 years and older, who underwent SWL in our clinic between December 2016 and December 2019 for the treatment of ureteral stones above the iliac crest level and had non-contrast enhanced abdominal computed tomography scans before the procedure were included in the clinical study. The results were evaluated at 3 months after SWL. The absence of residual fragments was considered as stone-free status, and the existence of any size residual fragment was considered as treatment failure.

RESULTS

In our study, the mean age of the patients was 42.4 ± 12.8 years, and the stone-free rate was 92.5%. The median transverse stone size was 7.5 mm (min 2.8-max 15), and the median UWT was 4.2 mm (1-8.7). In the multivariate analysis, UWT (P = .002) and multiple stone presence (P = .027) were found to be independent factors affecting stone-free status. In the receiver operating characteristic curve analysis, the optimal threshold value for UWT was determined as 5.25 mm.

CONCLUSIONS

We found that UWT was the most important independent variable associated with increased failure in SWL treatment. The presence of multiple stones was another independent factor that increased the failure rates. Using SWL technology through experience accumulated with the mechanical hardware of the machine, we can select patients who are more suitable for this treatment and improve treatment outcomes.

The relationship among plasma copeptin, carboxyhemoglobin, and lactate levels in carbon monoxide poisoning

OBJECTIVE

The aim of our study is to determine whether there is a change in the plasma levels of copeptin and there is a relationship among the plasma levels of carboxyhemoglobin (COHb), lactate, and copeptin levels in patients presenting to the emergency department with carbon monoxide (CO) poisoning.

METHODS

Fifty-seven patients admitted to the emergency department with CO poisoning were included in the study. The blood samples of the patients were collected on arrival 0th, 6th, and 12th hours for copeptin, lactate, and COHb levels. Data were analyzed using SPSS-17 statistical software.

RESULTS

Arrival serum copeptin levels of the patients were compared to copeptin levels of healthy individuals and a statistically significant difference was found between them (p = 0.008). There was a statistically significant difference between the arrival levels of copeptin and 6th-hour (p = 0.006) and 12th-hour (p = 0.001) levels of copeptin. There was no significant difference between 6th-hour and 12th-hour copeptin levels (p = 0.51). In terms of serum lactate levels, there was a significant difference between arrival and 6th h (p < 0.001), arrival and 12th h (p < 0.001), and 6th and 12th h (p < 0.001). Likewise, in terms of serum COHb levels, there was a significant difference between arrival and 6th h (p < 0.001), arrival and 12th h (p < 0.001), and 6th and 12th h (p < 0.001). There was a positive correlation between COHb and lactate levels on arrival (r = 0.52; p = 0.001).

CONCLUSION

Copeptin as a stress hormone can be used in the diagnosis and monitoring of patients with CO poisoning. However, the copeptin level was not superior to COHb and lactate levels.

A role of the endothelial nitric oxide system in acute renal colic caused by ureteral stone

BACKGROUND AND AIMS

Endothelial nitric oxide synthase gene polymorphisms play a role in some pathophysiological processes. In this study, the possible effects of endothelial nitric oxide synthase gene polymorphisms on ureteral stone disease in patients who were admitted to the emergency department with severe pain due to renal colic are examined.

MATERIALS AND METHODS

The study groups were designed as controls and patients. The control group was formed from the healthy volunteers who applied to the blood center next to the emergency service. The patient group comprised patients who were diagnosed with ureteral stone disease with severe pain. All of the genetic studies were based on extracted peripheral blood samples using the necessary procedures from the Genome and Stem Cell Center at Erciyes University (GENKOK). The data were analyzed with SPSS (IBM, ver 20, United Sate).

RESULTS

The study group comprised 62 females and 138 males, and the control group comprised 64 females and 136 males. All of the stones that caused renal colic were found to be localized in the ureters and the ureterovesical junction. The genotypes of the intron 4 polymorphism were found to be as follows: 4a/4a in 10 people, 4b/4a in 115, and 4b/4b in 275 people. The GG genotype of the eNOS-G894T polymorphism was found in 108 patients in the study group and in117 of the healthy individuals. There was no statistically significant difference between the two groups regarding these data.

CONCLUSION

Although this study is the first in the literature to examine the relationship between renal colic and endothelial nitric oxide synthase gene polymorphisms, our study demonstrated that no relation was found.
