Evaluation of the effect of shift working and sleep quality on semen parameters in men attending infertility clinic

We aimed to evaluate the effect of shift work on semen parameters together with the effect of sleep quality in men attending infertility clinic. The participants were divided into two groups as follows: 104 shift worker men (Group 1) and 116 nonshift worker men (Group 2). Groups were compared in terms of semen parameters, Depression Anxiety Stress Scale-21 (DASS-21), and Pittsburg Sleep Quality Index (PSQI) scores. A higher rate of oligozoospermia and poor sleep quality and a lower mean normal morphology percentage was observed in shift workers than nonshift workers (p = .006, .039 and .036 respectively). In addition, a positive correlation was seen between sleep duration and sperm concentration, while a negative correlation was found between sleep latency and total sperm count. Shift working together with high PSQI score was also a significant association with oligozoospermia when controlling for the other variables of age, total testosterone, DASS-21 stress score, smoking and varicocele (OR = 2.11, 95% CI 1.03–4.34 and OR = 1.18, 95% CI 1.01–1.39 respectively). In this study, infertile shift workers had a lower percentage of normal morphology and higher rates of oligozoospermia and poor sleep quality. Considering that shift workers have lower sleep quality, it seems that shift working negatively affects the circadian rhythm.     

Right ventricular free wall perforation during pericardiocentesis,and an inappropriate device selection for percutaneous treatment

Right ventricular (RV) perforation is a rare but life‐threatening complication of pericardiocentesis and is usually treated surgically. We presented a case of RV free wall perforation, which occurred during pericardiocentesis and tried to be closed percutaneously with the Amplatzer vascular plug‐III (AVP‐III) device. The occluder device sealed the perforation, but it was in an insecure position; therefore, the patient underwent surgical repair. As an AVP‐III device, with a middle disk thicker than the RV myocardium, it may cause the RV myocardium to stretch outwards, so it should not be used for the treatment of RV perforation by the transcatheter way.     

The Safety and Efficacy of Using Drainage in Arthroscopic Rotator Cuff Repair

PurposeThis study aimed to evaluate the effects of not using a drain or placing a drain in the glenohumeral (GH) or subacromial (SA) joint spaces on fluid retention and pain in the early postoperative period and late clinical outcomes.MethodsPatients who underwent arthroscopic rotator cuff repair between 2018 and 2020 were included in the study. Before the operation, demographic data, range of motion (ROM), visual analog scale (VAS) scores, Constant–Murley scores has documented. Deltoid muscle diameter (DMD) were measured. The total amount of irrigation used during the surgery and the operation duration were recorded, and the active amount of fluid coming from the drain in patients with a drain was recorded. The first postoperative DMD measure was made in the operating room and accepted as day 0. DMD measurements repeated postoperative first and second day. VAS assessments were performed on the postoperative first and second days. At the outpatient clinic, these measurements were repeated on the first and second weeks after discharge. Functional evaluations were made with ROM and Constant–Murley scores at the final follow-up examination.ResultsThere was no difference in the amount of drainage between the two groups in which a drain was used. When the three groups were compared among themselves regarding preoperative and postoperative VAS scores, Constant–Murley scores, and DMD, no significant difference was found.ConclusionsWe do not recommend the routine use of drains after arthroscopic rotator cuff surgery in terms of cost-effectiveness.Level of evidenceLevel II: Prospective Cohort Study.     

Solitary thoracic osteochondroma causing spinal compression: Case report

Spinal osteochondromas are very rare, and they present with nonspecific localized pain owing to bone involvement. Diagnosis is made based on direct X-ray and computed tomography (CT) imaging of the exophytic bone lesion with pedunculated or sessile structure. Although asymptomatic patients can be observed, surgical excision is the main treatment modality. We present the case of a 34-year-old man with solitary thoracic osteochondroma. The patient presented with complaints of pain in the legs, numbness, and inability to walk. The diagnosis was confirmed with CT imaging showing calcified heterogeneous bone lesion originating from the left side of T1-2 facet joint. After total excision, histopathological examination revealed the diagnosis of osteochondroma. No new clinical or radiological findings were detected in the 10-month follow-up.     

Analysis of factors among 30-day and 1-year mortality rates in patients with borderline stable-unstable intertrochanteric hip fracture

ObjectiveThis study aimed to evaluate the possible effects of surgical procedures on mortality and to identify the possible risk factors for mortality in the management of geriatric hip fractures.MethodsA total of 191 patients (105 women and 86 men; mean age 82.26±9.681 [60–108] years) with AO/OTA 31A2.2 intertrochanteric fractures and treated with sliding hip screw, proximal femoral nail, or hemiarthroplasty were included in this retrospective cohort study. The treatment type was decided by the responsible surgeon according to the patients’ pre-injury activity level, bone quality, and features of the fracture. Age, sex, type of fracture, type of surgery performed, American society of anesthesiology (ASA) grade, type of anesthesia, time to surgery, type of physical therapy, length of hospital stay, and number of comorbidities were documented. We evaluated the 30-day and 1-year mortality of patients treated with sliding hip screw (SHS), proximal femoral nail antirotation (PFN-A), or hemiarthroplasty and identified the possible risk factors for mortality.ResultsA total of 49 patients underwent SHS, 58 underwent PFN-A, and 84 underwent hemiarthroplasty. Of these, 2 patients with SHS, 2 with PFN-A, and 11 with hemiarthroplasty died within 30 days after surgery, whereas 7 patients with SHS, 15 with PFN-A, and 23 with hemiarthroplasty died 1 year after surgery. The 30-day and 1-year overall mortality rates were 7.9% and 23.6%, respectively. Both the 30-day and 1-year mortality risks were higher in patients undergoing hemiarthroplasty than in patients undergoing SHS (p=0.068 versus 0.058). The 30-day mortality was higher in patients receiving general anesthesia than in those receiving combined spinal and epidural anesthesia (p=0.009). The 1-year mortality risk was higher in patients with ASA grade 4 than in those with grade 1 and 2 (p=0.045). Advanced age (p=0.022) and male sex (p=0.007) were also found to be the risk factors for 1-year mortality.ConclusionWe demonstrated that higher ASA grade, male sex, general anesthesia, and hemiarthroplasty procedures are associated with higher mortality rates in elderly patients with hip fractures. Thus, we highly recommend orthopedic surgeons to consider all these factors in the management of intertrochanteric hip fractures in the geriatric population.Level of EvidenceLevel IV, Prognostic Study     

Synthesis and Characterization of Activated Carbon from Biowaste-Peanut Shell and Application to Preconcentration/Removal of Uranium

This study aims to synthesize and characterize an economical and ecological adsorbent with high adsorption capacity. For this purpose, the peanut shells (Pistacia vera L.) were modified chemically. After the synthesis of activated carbon (AC), the optimum conditions for enrichment steps were performed using parameters: pH and contact time for uranium in the model solutions. The measurements were carried out by inductively coupled plasma-mass spectrometry (ICP-MS). From the shapes of the BET isotherms, the AC obtained exhibits type I. The study indicated that the surface area and total pore volume of the AC were found to be 679.9 m² g⁻¹ and 0.31 cc g⁻¹, respectively. The adsorption capacity was found to be 260 mg g⁻¹. The optimum pH was found to be 6.0 for enrichment using the AC obtained by sulfuric acid as a chemical-modifier. The optimized method was applied to enrichment of U at ppb levels in the model solutions.

Copper ion-mediated modification of bases in DNA in vitro by benzoyl peroxide

The mouse skin tumor promoter benzoyl peroxide (BzPO), in conjunctionwith Cu(I), causes promutagenic damage in DNA. Because freeradical intermediates are produced by the reaction of BzPO withCu(I), we sought to determine whether BzPO plus Cu(I) causedDNA base damage typical of that caused by the hydroxyl radical.A broad range of modified DNA bases were measured by GC-MS withselected-ion monitoring after exposure of purified plasmid pCMVßgalDNA to BzPO ± Cu(I). Exposure to BzPO/Cu(I) caused upto 20-fold increases in the levels of adenine-derived modifiedbases, and only a <2-fold increase in thymine-derived modifiedbases. The guanine-derived modified base 8-hydroxyguanine waselevated to the highest net amount, 160 molecules/10⁵ DNA bases.Exposure to BzPO alone or Cu(I) alone induced only minor (<<2-fold) DNA base modification. Also, benzoic acid, the majornon-radical metabolite of BzPO, or BzPO plus Fe(II) were ineffectiveat inducing DNA base modification. The hydroxyl radical scavengerdimethyl sulfoxide inhibited BzPO/Cu(I)-induced base modificationby 10–50%. These data suggest that the reaction of BzPOwith Cu(I) generates hydroxyl radical or a similarly reactiveintermediate which causes DNA base damage. This damage may beresponsible for BzPO/Cu(I) mediated mutagenesis.
