A 60-year-old woman had central retinal artery occlusion (CRAO) presented to the ophthalmology department with a sudden, painless loss of vision. Her initial visual acuity was light perception and she treated with hyperbaric oxygen therapy (HBOT) 4 hours after the development of visual symptoms. Systemic risk factors were not found so she was diagnosed as having idiopathic CRAO. Her vision improved from light perception to 20/50 after the HBOT. Any complications such as neovascularization were not developed until the last follow up visit of 8th months.

The article presents data from recent publications and own data on screening studies with interpretation of chest radiographs using artificial intelligence CAD (Computer-Assisted Diagnosis), which, according to WHO recommendations, provides more accurate clinical thresholds for deciding who needs to take a sputum test. Another aspect of the WHO recommendations is the cost-effectiveness of CAD as a tool for triaging patients with tuberculosis symptoms in low-income countries with a high incidence of tuberculosis. Compared with smear microscopy and GeneXpert, without preliminary sorting, the use of mobile digital X-ray machines equipped with a CAD tool reduces costs, allowing sorting of individuals suspected of having tuberculosis for testing on GeneXpert, while reducing the time to start tuberculosis treatment.Thus, conducting a study using portable X-ray machines using a CAD program is a low-cost and easy-to-implement method, does not require large funds, does not require separate rooms, is highly effective, has good image quality, allows you to quickly clarify individuals suspected of having tuberculosis, differentiating it from other pathological changes in the lungs.Our experience shows that machine analysis of chest computed tomography data, due to the higher resolution capabilities of the method and the absence of fundamental disadvantages of radiography, including the effect of shadow summation, the presence of “blind” zones, etc., is finding increasing application in both diagnostics and screening of respiratory diseases. Our use of this tool allowed us to identify additional new cases of phthisio-onco-pulmonary diseases in field conditions.

Coronary heart disease (CHD) seriously endangers human health, and there are obvious gender differences in incidence rate and prognosis, which are related to the evident differences in anatomical structure, physiological characteristics, and wall shear stress between males and females. In recent years, cardiac rehabilitation has been proven to be safe and effective in controlling the progression and improving the prognosis of CHD. Thereinto, exercise therapy is the central link of cardiac rehabilitation. Exercise can significantly affect vascular endothelial function by regulating wall shear stress. Based on previous research, this paper will briefly review the influence of exercise on wall shear stress in male and female patients with CHD, in order to provide a reference for formulating personalized cardiac rehabilitation programs and further improve the prognosis of CHD.

The ability to live things to transfer their genetic heritage to future generations in a healthy way forms the basis of the science of reproduction. In this sense, understanding the structure and functions of the sperm cell, which is one of the sexual cells, is one of the important issues that should be emphasized. Methods such as omics, genomics, proteomics, and metabolomics, which have been found in research in recent years, are also used to evaluate the functions of the sperm cell.

Background and importance: Sacral fractures often lead to injuries of the lumbosacral nerve, which will cause tremendous damage to the patient’s motor and sensory functions. At present, the most commonly used surgical method is the posterior median approach, the extent and degree of neurolysis are often insufficient, so the effect of neurolysis is not well, and the functional recovery of patients after operation is often incomplete.Clinical presentation: The patient was a 17-year-old male who accidentally fell from a height and landed on his hip. The main clinical feature of the patient was persistent radiating pain in the right lower extremity with right lower limb sensorimotor disorder. The results of the X-ray examination indicated a sacral fracture and a right pubic fracture. After the injury, the patient underwent pelvic internal fixation surgery within 72 hours. Then 6 months after the surgery, there was no significant improvement in right lower limb function, and the patient came to our hospital seeking treatment. Considering the severe lumbosacral plexus injury and the history of surgery, we performed an “Anterior surgery approach combined with posterior approach for lumbosacral neurolysis” for the patient, postoperative radiation pain disappeared completely, and there were significant improvements in the muscle strength of some muscles and sensory function.Conclusion: The relaxation of the lumbosacral plexus is usually performed through a single surgical approach, which has great limitations in the effect of relaxation. Here, we demonstrate a case in which posterior lumbar incision and anterior laparoscopic lumbosacral plexus neurolysis can benefit the patient, the lumbosacral nerve was released to a great extent. We aim to bring this case to the attention of our worldwide neurosurgical colleagues and share our surgical approach to assist those who may encounter this case in the future.

With increasing awareness of the mental health issues among the clergy and seminary students, it is important to explore possible interventions to help address their mental health concerns. This pilot study examined the impact of Christian meditation and biofeedback on levels of stress, anxiety, and depression of seminary students. Participants of this study included 20 theology students from two seminary campuses. Participants were of various ethnic backgrounds and had an average age of 31. At the beginning of the study, participants were randomly assigned to practice either Christian meditation or biofeedback for 4 weeks, three times per day, and to keep a log of their practice times. The results from the paired samples t-tests indicated that both Christian meditation and biofeedback significantly reduced the levels of stress, anxiety, and depression experienced by the participants. ANCOVA indicated that neither intervention was more effective than the other. Seminaries, churches, and pastoral care groups should look into these interventions as a good source to help their clergy cope with stress, anxiety and depression.

The present study aimed to analyze Cholinesterase (CE) levels in cord blood from preeclamptic women and to evaluate cholinesterase status in patients with osteosarcoma. Serum cholinesterase levels were assessed in 30 cases of osteosarcoma and 30 controls suffering from musculoskeletal pain. Additionally, maternal and cord blood samples were collected from 25 women with preeclampsia and compared with those from 25 normotensive pregnant women and 25 normal, healthy controls. The results indicated that serum cholinesterase levels were significantly lower in osteosarcoma patients (Group I) compared to those with musculoskeletal pain (Group II, p < 0.05). Similarly, cholinesterase levels were reduced in the maternal blood of women with preeclampsia when compared to normotensive controls. Cord blood cholinesterase levels were lower in the infants of normotensive mothers, with levels reaching 88.65% of the maternal levels. Furthermore, cord blood cholinesterase levels were significantly lower in preeclamptic women compared to normotensive pregnant women. When comparing cholinesterase levels to those of normal controls, it was observed that CE levels were significantly elevated in both normotensive and preeclamptic women. The findings of low serum cholinesterase levels in this study suggest that cholinesterase secreted by osteoblasts is utilized in bone formation and tumorigenesis. Additionally, the decrease in cholinesterase levels associated with preeclampsia may be linked to the loss of muscarinic cholinergic receptors that occur in this condition.

Background: The burden of depression as a mental disorder has continued to increase and constituting an enormous public health concern among all age groups. A number of socio-demographic, and other factors including a stressful and rigorous academic programme or curriculum such as the one run in most medical schools could contribute to the occurrence of depression among medical students. AIM: To determine the socio-demographic and other factors associated with depression among medical students in the University of Port Harcourt. Methodology: This study was a descriptive cross-sectional study. Appropriate sample size was calculated and the stratified random sampling method was used to select the subjects. A well-structured open ended self-administered socio-demographic questionnaire was administered to the students. The Zung Self-Rated Depression Scale was used to assess the depression status of each respondent. The data were analyzed via descriptive and analytical methods. Results: The prevalence of depression among the medical students was 5.3%. Fourteen students (4.6%) were mildly depressed while only two respondents had moderate depression. Year 3 had the highest prevalence with 10.5% followed by final year with 5.3%, while the only 2 cases of moderate depression were found among students in year 2 of their medical programme. Two hundred and seventy-one respondents (88.8%) were found to have good knowledge of depression, 32 (10.5%) were found to have average knowledge of depression and 2(0.7%) had poor knowledge of depression. Conclusion: Depression does occur among medical students at the University of Port Harcourt albeit low, and was associated with a number of socio-demographic and other factors. The present medical curriculum and programme should be sustained and more efforts at making it less stressful and academically friendly, be made to further reduce the current rate of psychological stress and depression among the students.

The theoretical concept of photonic quantum nonlocality cannot be implemented physically because of the quantum Rayleigh scattering of single photons. Physical scrutiny of landmark experiments (December 2015, M. Giustina, et al. Phys. Rev. Lett. 115, 250401, and L. K. Shalm, et al., Phys. Rev. Lett. 115, 250402) is undertaken. These articles reported that measured outcomes were fitted with quantum states possessing a dominant component of non-entangled photons, thereby contradicting their own claim of quantum nonlocality. With probabilities of photon detections lower than 0.1%, the alleged quantum nonlocality cannot be classified as a resource for developing quantum computing devices, despite recent publicity. Experimental evidence of a feasible process for quantum-strong correlations has been identified (M. Iannuzzi, et al., Phys. Lett. A, 384 (9), 126200, 2020) in terms of correlations between independent and multi-photon states evaluated as Stokes vectors on the Poincaré sphere. As single-photon sources are not needed, the design and implementation of quantum computing operations and other devices will be significantly streamlined.

The problems of reproduction in the camel are not extensively investigated as in the bovine, caprine and ovine species. There is need to elucidate the problem in detailed in order to overcome the problem of production and genetic multiplication. The information collected on these problems is derived mainly from questioning the camel owners, slaughterhouse material and very limited clinical and farm observations.
