In the context of organizations and their relationship with the increasingly competitive environment, leaders have been pressured to establish control systems in which the differences between employees are exacerbated since, in the absence of labor competencies, these are They are intended to substitute for acts of loyalty to the company that lead to violence towards those who are the culprits of poor performance or are not seen as part of a working group. This is how organizational violence is justified within collaborative teams, as would be the case of Higher Education Institutions where the phenomenon is exacerbated with the emergence of electronic technologies, devices, and networks. The objective of this study was to establish the reliability and validity of an instrument that measures organizational violence. A non-experimental, cross-sectional, and confirmatory study was carried out with a non- probabilistic selection of 100 students from a public university in central Mexico. The results in general show that organizational violence would be made up of eight factors such as: prejudice, depersonalization, benevolence, harassment, subjugation, objectification, stigma, and harassment, which show the limits of the study and guidelines of research concerning equity.

Glycogen is an important energy reserve in the brain and can be rapidly degraded to maintain metabolic homeostasis during cerebral blood vessel occlusion. Recent studies have pointed out the alterations in glycogen and its underlying mechanism during reperfusion after ischemic stroke. In addition, glycogen metabolism may work as a promising therapeutic target to relieve reperfusion injury. Here, we summarize the progress of glycogen metabolism during reperfusion injury and its corresponding application in patients suffering from ischemic stroke.

The diagnosis of bipolar disorder in children and adolescents has not progressed among child psychiatrists despite increasingly solid data. It is unipolar depression, anxiety disorders including panic attacks and of course hyperkinesia with attention deficit disorder that are at the top of the bill. This is how adult psychiatrists inherit bipolar patients whose diagnosis was ignored in childhood or adolescence, often dormant for years. The diagnostic guidelines, although not perfect, quickly lead to the diagnosis of bipolar disorder, especially as when parents are questioned, there are arguments leading to family disease. If mood stabilizers are little or no effective before the age of 12, they can be used successfully after that age. Behavioral therapies can take over or methylphenidate in the case of obvious school problems.

Looking at the state of knowledge on the biological etiology of disorders of thought and mood as neuropathologist, I have encountered a broad range of associations between genetic and epigenetic findings, various relations to the contemporary knowledge on the importance of connectivity, neurotransmission, and modulation by neuropeptides, but nothing appeared sufficiently specific, so far. Taking disorders such as schizophrenia, anxiety, or autisms as examples I have critically reviewed and commented seven main hypotheses on the etiology of mental disorders. The often mutually exclusive or contradictory hypotheses are each fascinating in their highly sophisticated approaches, but remain altogether confusing; is there anything not responsible for disorders of thought and mood? If illnesses are poorly understood, they are poorly treated.

Objective: Recurrent cerebral ischemic events are estimated to appear in between 12-15% of symptomatic intracranial atherosclerotic disease (ICAD), regardless of the use of leading pharmacological therapies. Balloon expandable stent (balloon mounted coronary stent) could represent a feasible alternative in this disease’s treatment. This study pretends to report the balloon-expandable placement experience in our center. Materials and Methods: A unicentric retrospective study dated between September 2009 and March 2018 was conducted. Patients previously diagnosed with ICAD and symptomatic stenosis treated with balloon-expandable stent were included. Clinical features, morbidity, mortality, short and long-term evolution, and pre-and post-treatment angiographic features were analyzed, as well as a mean 8 years-period follow-up. Data are presented as means, frequencies, and percentages for categorical variables, and ranks for continuous variables. Statistical analysis was carried by IBM SPSS Statistics Base V22.0 (IBM Corporation, Mexico). A Wilcoxon Signed-rank test statistical analysis was performed. Statistical significance was considered when a p-value lesser than 0.05 was measured for every result. Results: A total of 6 patients with 7 affected vessels were treated, with an average age of 62.7 years. Affected and treated vessels were located in the Internal Carotid Artery (ICA) segment in 42.9%, Vertebral Artery (VA) V4 segment in 14.3%, Middle Cerebral Artery (MCA) M1 segment in 28.5%, and Posterior Cerebral Artery (PCA) P1 segment in 14.3%. The incidence of peri-operatory thrombotic events was 0%. Intracranial hemorrhage presented in 0% of cases. Recurrent ischemic or thrombotic events were not reported in a 97-months mean follow-up. 71.4% of patients scored ≤2 in the modified Rankin Score (mRS) pre-treatment, in a 90 day and 12-month follow-up. 100% presented a favorable evolution with mRS ≤2. Restenosis cases were not reported in radiologic control and retreatment was not needed in a 97-month mean follow-up. Conclusions: This study suggests that balloon-expandable stent therapy with some technical endovascular variants for its navigation and placement could be a safe and effective alternative in the treatment of ICAD as a means of cerebral ischemic event early secondary prevention. We propose to consider not to limit endovascular treatment exclusively to those symptomatic ICAD patients refractory to medical-exclusive treatment, as a means to reduce the risk of presenting a new neurological deficit. Further expanded clinical trials are needed to confirm these findings and the advantage of this kind of stents against other kinds reported in the literature.

Spontaneous epidural hematoma during pregnancy is rare but it requires urgent diagnosis and decompressive surgery because the prognosis is mainly linked to the speed of treatment. Reporting the case of a pregnant woman in the 8th month of pregnancy who presented back pain with paraplegia, an MRI was performed on her returning in favor of a compressive hematoma at the D1D2 level. Followed by a D1D2 laminectomy with evacuation of the hematoma. The postoperative period is marked by total neurological recovery.

The lipomyelomeningocele (LMMC) is a type of congenital occult spinal dysraphism consistent with the presence of lipomatous tissue adhering to the epinetic marrow, which falls through a defect of the vertical colon with the former meninges and the marrow under posture the skin. LMMC is the cause of the most frequent congenital attache between the cadre of the syndrome of the attached cord and causes a neurological deterioration due to the compression of the medical bone and the root system which is superadded. It is therefore about a girl from 6 years ago with a swelling located in the region of Lombardy after the birth of the size of a tangerine which has increased the size gradually with age. He presented the interrogation of the signs of urinary incontinence and the fact that he confirmed that he left us to fellow therapists who sent him to us for support. The local examination of the lumbosacral region revealed a single mass without other distinctive skin signs, spherical in shape, 12 × 10 cm, soft and fixed in consistency. A medullary MRI with effect, which reveals a mass of lipomate consistency at the level of lumbosacral associated with a bone spina extending from L5 to S2. Surgical treatment was indicated as the patient had urinary problems. There were no postoperative complications and after a few months postoperative symptoms improved.

Objective: To study the pathomorphosis of vascular dementia over the past 30 years. The study of the pathomorphosis of mental disorders makes significant adjustments to the criteria for diagnosis and nosography. Dementia has also undergone pathomorphosis over the years. Materials and Methods: The research was carried out in the Psychiatric Hospitalsin Azerbaijan. A retrospective analysis was carried out for the period 1990-1999, which were compared with a similar contingent during 2010-2020. Results: The number of hospitalized patients with vascular dementia has increased over the past 10 years, which means both an increase in the incidence of the disease and an increase in symptoms requiring psychiatric treatment. Conclusions: Pathomorphosis has also manifested itself in sex. Thus, the number of female patients has increased in the last 10 years. As a result of the disease, there is a positive trend, a decrease in mortality.

Angiosarcomas also called hemangioendothelia, are rare and highly malignant vascular tumors of mesodermal origin, they represent 08-10% of cancers and can affect any part of the body.Angiosarcoma mainly affects the skin, the face is the preferred topography in adults, it remains exceptional in children, with a predilection for the mediastinum and pericardium,The angiogenesis of angiosarcomas is still poorly understood; However, chronic lymphedema and exposure to prolonged radiotherapy are blamed. Total surgical excision is the treatment of choice in localized forms, followed by chemotherapy. pre- and post-operative radiotherapy may be necessary.New studies have shown the effectiveness of beta blockers (propranolol) in the management of angiosarcomas.The prognosis depends on the age of the patient, the size of the tumor, the histological grade and the extent of tumor progression.
