AbstractBackground: Lumbar spondylolysis is a stress fracture of the lumbar vertebral arch that occurs frequently in adolescents. Lumbar spondylolysis has a high prevalence in athletes, especially baseball players. When lumbar spondylolysis occurs, restriction of sports activities is inevitable until the bony union is achieved. Therefore, prevention of the onset of lumbar spondylolysis is necessary, and it is necessary to elucidate the risk factors that influence the onset of the disease. An increase in lumbar lordosis angle may influence the development of lumbar spondylolysis because the lumbar lordosis angle increases the compressive stress in the vertebral arch. However, there are no reports on the effect of lumbar lordosis angle and the development of lumbar spondylolysis in adolescent baseball players. Therefore, the purpose of this study was to investigate the effect of lumbar lordosis angle on the development of lumbar spondylolysis in adolescent baseball players. METHODS: Eligible patients were those who visited the orthopedic clinic from January 1, 2018, to October 31, 2021. The selection criteria were male baseball players aged 11-18 years who visited the clinic, and the exclusion criteria were those whose superior endplate of L1 and superior endplate of S1 could not be identified in the MRI images. The existence of development of lumbar spondylolysis, lumbar lordosis angle, age, and pitching experience of the above patients will be assessed based on electronic medical records and imaging findings. Statistical analysis was performed using logistic regression analysis, with the objective variable being the existence of lumbar spondylolysis and the explanatory variables being the lumbar lordosis angle, age, and previous pitching experience.Discussion: This study examines the effect of the lumbar lordosis angle on the development of lumbar spondylolysis in adolescent baseball players. An increase in lumbar lordosis angle may influence the development of lumbar spondylolysis and may be a risk factor for the development of lumbar spondylolysis.

Abstract Background: If bone union is expected, conservative treatment is generally selected for lumbar spondylolysis. However, sometimes conservative treatments are unsuccessful. We sought to determine the factors associated with failure of bony union in acute unilateral lumbar spondylolysis with bone marrow edema including contralateral pseudoarthrosis.Methods: This study targeted unilateral lumbar spondylolysis treated conservatively in high school or younger students. Conservative therapy was continued until the bone marrow edema disappeared on MRI and bone union was investigated by CT. We conducted a univariate analysis of sex, age, pathological stage, lesion level complicating the contralateral bone defect, lesion level, and intercurrent spina bifida occulta, and variables with p < 0.1 were considered in a logistic regression analysis. An item with p < 0.05 was defined as a factor associated with failure of bony union.Results: We found 92 cases of unilateral spondylolysis with bone marrow edema and 66 cases were successfully treated conservatively. Failure of bony union in unilateral lumbar spondylolysis with bone marrow edema was associated with advanced pathological stage (p = 0.004), contralateral pseudoarthrosis (p < 0.001), and L5 lesion level (p = 0.002). The odds ratio was 20.0 (95% CI 3.0–193.9) for advanced pathological stage, 78.8 (95% CI 13–846) for contralateral pseudoarthrosis, and 175 (95% CI 8.5–8192) for L5 lesion level.Conclusions: Conservative therapy aiming at bony union is contraindicated in cases of acute unilateral spondylolysis when the pathological stage is advanced, the lesion level is L5, or there is contralateral pseudoarthrotic spondylolysis.

Background Although segmental wire fixation has been successful in the treatment of nonathletes with spondylolysis, no information exists on the results of this type of surgery in athletes. Purpose To evaluate the outcome of surgical repair of pars interarticularis defect by segmental wire fixation in young athletes with lumbar spondylolysis. Methods Between 1993 and 2000, 20 athletes (6 women and 14 men; average age, 23.7) with lumbar spondylolysis were treated surgically with this technique. They were actively engaged in sports such as baseball, tennis, and golf. Nineteen athletes had one level of spondylolysis and one athlete had two levels. The level of spondylolysis was L4 in 2 athletes and L5 in 19. The average follow-up period was 3.5 years (range, 1.3 to 8.6). Surgical outcome was evaluated by radiographic examination, the Japanese Orthopaedic Association score, preoperative and postoperative sports activity levels and intensities, and the presence of complications. Results Bony fusion at the site of spondylolysis was obtained in all cases, and the Japanese Orthopaedic Association score was increased significantly after surgery (preoperatively, 21.2 ± 3.9; postoperatively, maximum 27.7 ± 1.0; recovery rate, 80.4%). All of the patients returned to their sports activities, although at varying degrees. No severe complications were noted. Conclusion We recommend this technique in cases of lumbar spondylolysis in athletes who hope to resume their sports activities.

Abstract Objective To identify a diagnostic indicator of lumbar spondylolysis visible in plain X-ray films. Methods One hundred and seventy-two patients with low back pain who received X-ray and computerized tomography (CT) examinations were identified and studied. They were divided into three groups: the spondylosis without spondylolisthesis (SWS) group, comprising 67 patients with bilateral pars interarticularis defects at L5 and without spondylolisthesis, the isthmic spondylolisthesis (IS) group, comprising 74 patients with L5/S1 spondylolisthesis and bilateral L5 pars interarticularis defects, and the control group, comprising 31 patients with low back pain but without spondylolysis. The sagittal diameters of the vertebral arch (SDVAs) of L4 and L5 were measured in lateral X-ray image, and the differences in SDVA between L4 and L5 (DSL4-5) in each case were calculated and analyzed. Results There were no significant differences in demographic characteristics among the three groups. In the SWS and IS groups, the SDVA of L5 was significantly longer than the SDVA of L4 (p < 0.001), whereas no significant difference found in the control group (p > 0.05). DSL4-5, in which the SDVA of L4 was subtracted from the SDVA of L5, significantly differed among the three groups (p < 0.001), and the normal threshold was provisionally determined to be 1.55 mm. Conclusions In bilateral L5 spondylolysis, the SDVA of L5 is wider than the SDVA of L4, and this difference is greater in isthmic spondylolisthesis. This sign in lateral X-rays may provide a simple and convenient aid for the diagnosis of spondylolysis.

Purpose: As a higher cognitive function is controlled Executive function by frontal cortex. It is consisted of Decision-making، planning، inhibition، organization and working memory. According to high prevalence of executive dysfunction in adults with neurological disorders such as Dementia and stroke and considering to applying appropriate tests in neurological patients and aging people in order to diagnose executive dysfunction quickly and correctly، In this study we aimed to review common and quick executive function tests.Methods: This research was a review study on common and quick executive function tests in adults. A search was conducted using some databases including Iran medex، SID، Magiran، Google scholar، Medline، Science Direct، Scopus and Web of Science. The tests were investigated regarding to the date of publishing، method of administration، target populations، subscales، time administration and psychometric features.Results:  According to inclusion and exclusion criteria of this study، we found 26 common and quick tests، Most of them were in English and just one of them was a Persian version. Thirteen tests of them were translated or modified version of original English test. Ten tests of them were very quick with average administration time about 10 minute and the other need 30 minute to administer.Conclusion: Regarding to importance of evaluating of executive function in neurological patients especially individuals with Dementia beside  existence of  a lot of tests   in other languages and  lack of quick executive function tests in Persian , results of current study  can help neurologist, speech and language pathologist and other experts to be familiar with common quick tests  and their clinical application. These results also recommend researchers and clinicians to translate and adapt some of  the quick and easy administer Executive function  tests in Persian.

Objective: To estimate the prevalence of SARS-CoV-2 antibodies in an asymptomatic population in the state of Sergipe, Brazil. Methods: This cross-sectional study with stratified sampling (sex and age) includeD serological immunofluorescent tests for IgM and IgG on samples from 3 046 asymptomatic individuals. Sample collection was performed in wet-markets of the 10 most populous cities of Sergipe, Brazil. Exclusion criteria included symptomatic individuals and health workers. The presence of comorbidities was registered. Results: Of the 3 046 participants, 1 577 (51.8%) were female and 1 469 (48.2%) were male; the mean age was 39.76 (SD 16.83) years old. 2 921 tests were considered valid for IgM and 2 635 for IgG. Of the valid samples, 347 (11.9% [CI 10.7%–13.1%]) tested positive for IgM and 218 (8.3% CI 7.2%–9.4%]) tested positive for IgG. Women over 40 had the highest prevalence for IgM (group C, p=0.006; group D p=0.04). The capital Aracaju displayed the highest prevalence for both antibodies; 83 (26.3% [CI 21.6%-31.6%]) tested positive for IgM and 35 (14.6% [CI 10.4%-19.7%]) for IgG. The most prevalent comorbidities were hypertension (64/123 individuals) and diabetes (29/123). Conclusions: A high prevalence of SARS-CoV-2 antibodies was found among asymptomatic persons in Sergipe. Women over 40 showed the highest rates. The capital, Aracaju, displayed the highest seroprevalence. Surveys like this one are important to understand how the virus spreads and to help authorities to plan measures to control it. Repeated serologic testing are required to track the progress of the epidemic.

Aims/objectives: Coronavirus pandemic has been declared a health emergency worldwide. Millions of people have been affected by it. The objective of this study was to assess anxiety and depression among people who are confined to their homes due to the covid-19 pandemic so that measures can be taken to reduce the frequency and effects of psychological distress during mass lockdowns in the future.Materials and methods: The study population consisted of educated adults of Rawalpindi and Islamabad who have been under strict lockdown. A non-probability convenience sampling technique was used. Informed consent was taken. Data were collected via a questionnaire based on the HADS scale. For data analysis, SPSS version 25 was used.Results: This descriptive, cross-sectional study was conducted among 615 individuals, out of which 15 did not meet the inclusion/exclusion criteria. The majority were females (80.2%). The average age was 22.6 years. 37.5% were found to have anxiety, whereas 21% had depression. Borderline cases of anxiety and depression were 27.5% and 28.3%, respectively. The frequency of anxiety and depression was found to be higher in females than males, 39.5% vs 29.4%, and 22.4% vs 11.5% respectively. The correlation of HADS scores with other demographic parameters was studied, but no significant relationship was found.Conclusions: The study reveals a high prevalence of anxiety and depression among individuals during lockdowns. The development of a comprehensive educational and emotional support system is required for the improvement of the mental health of individuals.
