Revisiting Indifference inside Alzheimer's: Through Conceptualization to Restorative Methods.
Septorhinoplasty by disarticulation is an esthetic and functional solution for naturally occuring nasal pyramid dysmorphia, releasing the anatomic traces of growth-related stresses. Disarticulating the septolateral cartilage from its bony framework via a closed approach to the septal pocket is associated to Rethi's external approach in order to disarticulate the fibrocartilaginous nasal dorsum, while conserving its integrity, under the bony dorsum. The bony pyramid is then disarticulated down to the nasion, after resecting any bone hump, by 2 paramedian and 2 low lateral osteotomies in the basal groove. The lateral sides of the bony pyramid are then fractured at their posterior edges by percutaneous pinching to close the open roof and realign them along the midline. The septolateral cartilage, reduced as necessary at the inferior and anterior edges, is thereafter repositioned on the premaxillary bone. Traction on its anterior edge restores rectilinear frontal and lateral tension in the fibrocartilaginous dorsum, fully conserved from its attachment to the nasion. This technique corrects any septal deformity and restores frontal and lateral dorsum straightness.There are several slightly invasive methods to detect colorectal carcinoma (CRC) including colonoscopy and sigmoidoscopy; but there is no noninvasive, accurate screening test. It is recommended to initiate screening at the age of 50 for non-familial CRC. Laboratory tests are routinely suggested if internal observation and imaging are recommended for further evaluation. Spectroscopic-based imaging, such as magnetic resonance spectroscopy (MRS) is an interesting and promising tool with the potential to be an alternative to some minimally invasive procedures, such as biopsy. Accordingly, MRS might be a suitable substitution for invasive methods, such as colonoscopy. This article aimed to review the studies that have evaluated the MRS technique as a screening tool in CRC.
Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the digestive tract with malignant potential. The current risk classification standard is unable to accurately evaluate the invasiveness and clinical outcomes of GISTs. Ki-67 labelling index (LI) may be an effective indicator in assessing tumour invasiveness and prognosis, however, its exact value in GISTs is still uncertain. The aims of our study were to evaluate the correlation of the Ki-67 LI and clinicopathological features of GISTs and to assess the potential value of the Ki-67 LI in GISTs classification and prognosis.

The clinical, pathological and prognostic data were collected and analysed to identify the independent influential factors of GISTs risk stratification and the predictors of GISTs prognosis.

The Ki-67 LI was significantly associated with the clinicopathological features of tumour progression (P<0.05). It was an independent influential factor of GISTs risk classification (odds ratio 1.322; 95% confidence interval 1.031-1.696) (P=0.028), and the area under the curve (AUC) value of the Ki-67 LI on the discrimination ability of GISTs risk stratification was 0.906 (P<0.001). The optimal cutoff value of the Ki-67 LI was 6% (sensitivity of 87.5% and specificity of 76.2%), and patients with Ki-67 LI≥6% exhibited significantly poorer progression-free survival (PFS) than those with Ki-67 LI<6% (P<0.001). The AUC value of the Ki-67 LI for predicting PFS in postoperative patients was 0.813 (P=0.03).

The Ki-67 LI has appreciated value to predict the risk grade and prognosis of GISTs. Patients with Ki-67 LI≥6% are prone to recurrence and metastasis after operation and may need a close follow-up.

It can mimic pancreatic cancer, leading to errors in diagnosis and treatment increasing rates of morbidity and mortality in patients. The aim of this review is to take a differential diagnostic approach to these two entities using epidemiology, clinical and laboratory findings, imaging and histopathology.
Eating disorders (ED) constitute an important group of conditions that commonly occur in adolescents. Gastrointestinal complaints are frequently reported in ED patients. Few studies assessed the association of irritable bowel syndrome (IBS) with ED. The aim of the current study is to determine the prevalence of ED in a group of IBS patients and compare it with a healthy control group and assess the relationship of IBS sub-types, it's duration and severity with ED.

100 IBS patients diagnosed according to the Rome-IV criteria and a control group consisting of 100 healthy adults, between 18 and 65 years old, were enrolled in this study. Sub-type, duration and severity of IBS were determined. All participants were requested to fill questionnaires to screen for ED.

200 subjects participated in the study. 118(59%) were female and 92(41%) were male. BBI608 The Eating Attitudes Test (EAT) score was significantly higher in the IBS group (Odds ratio 5.3 CI 95%4.3-9.3; p<0.001). The number of subjects with EAT score >30 was significantly higher in the IBS group (p<0.001). EAT scores were significantly higher in female IBS patients and in younger patients (p=0.013 and p=0.043; respectively). No significant association between the IBS sub-type and EAT score was found (p>0.05). However, IBS severity and duration positively correlated with EAT scores.

ED should be considered in the management of IBS patients. Since many psychological factors can exacerbate IBS symptoms a multidisciplinary approach consisting of medical and behavioral therapeutic modalities should be employed for a better management of these patients.

Air pollutants such as sulfur oxides, nitrogen oxides, carbon monoxide and dioxide, particulate matter (PM), ozone and volatile organic compounds (VOCs) are commonly found at high levels in big cities and/or in the vicinity of different chemical industries. An association between air concentrations of these pollutants and human respiratory viruses interacting to adversely affect the respiratory system has been also reported. The present review was aimed at assessing the potential relationship between the concentrations of air pollutants on the airborne transmission of SARS-CoV-2 and the severity of COVID-19 in patients infected by this coronavirus. The results of most studies here reviewed suggest that chronic exposure to certain air pollutants leads to more severe and lethal forms of COVID-19 and delays/complicates the recovery of patients of this disease.
The easy-to-calculate gender, age, and lung physiology (GAP) model shows good predictive and discriminative performance in the prognosis of idiopathic pulmonary fibrosis (IPF). However, the GAP model was not effective in predicting the prognosis accurately in previous Japanese and Korean IPF cohort studies. Therefore, we developed a modified GAP model for the East-Asian populations by weighing the GAP variables. The validity of the modified GAP model was subsequently evaluated in East-Asian IPF patients.

The derivation cohort comprised 326 patients with IPF. Weights of the variables were adjusted on the basis of coefficients derived from Cox regression models. The total points were distributed to the three stages of the disease so that the number of patients included in each stage was appropriate. The validity of the modified model was analyzed in another Japanese cohort of 117 patients with IPF and a nationwide cohort of Korean patients with IPF.

Predicted survival rates differed significantly in the derivation cohort using the modified GAP model for each stage of IPF (log-rank test stage I vs. stage II, p<0.001; stage II vs. stage III, p<0.001). Model performance improved according to Harrell's C-index (at three years 0.696 in the original GAP model to 0.738 in the modified model). The performance of the modified model was validated in the Japanese validation and Korean national cohorts.

Our modification of the original GAP model showed improved performance in East-Asian IPF patient populations.

Transfusion is either a discipline or a subsidiary of others depending on the countries and systems; this variability can be explained because transfusion is a medical care that is transdisciplinary. As a collective of professionals in both transfusion medicine practice and education, authors aim to propose a revision of the way education in transfusion medicine is delivered in this era of the 'global competency approach'. They advocate in favor of a Know How on 5 key issues Diagnosing the patient condition in line with the Patient Blood Management principles; Facing acute blood loss; Addressing compatibility and avoiding immunization; Seeking for maximized benefits and dampening complications; and Inlaying competence within global health care issues, also comprising od economy. The methods used would be those developed for medical education at large, such as assessment tools. The global objective is to deliver the necessary competence to manage patients by an intern/resident. At the end of the curriculum, students should be able to self-evaluate the following items 1) Do I know why my patient is anemic, thrombocytopenic, bleeding….? 2) Do I know the best approach to treat anemia, thrombocytopenia, bleeding (including the "no treatment" option)? 3) Do I know whether a transfusion approach is appropriate for my patients? 4) Do I know how to evaluate and anticipate benefits from blood transfusion and to avoid side-effects in the patient? 5) Do I know how to avoid unnecessary use of the products?
Hemolytic reactions are adverse complications associated with red blood cell transfusion. These reactions are associated with clinically important erythrocyte antigens, such as those of Duffy blood Meny (2010). Individuals with the Duffy null phenotype Fy (a-b-) are more likely to develop an alloimmunization reaction, resulting in an incompatibility with all available red blood cell units, thus increasing the risk of complications from their underlying disease Höher et al. (2018). Hence, it is important to determine the prevalence of the Fy (a-b-) phenotype in blood donors in our population and to create a database to ensure safe transfusion in patients with this phenotype. Moreover, we intend to establish whether there is any relationship between individuals with this phenotype and the sickle cell trait. We conducted this study to measure the prevalence of the Fy (a-b-) phenotype in our blood donors.

This prospective, descriptive study included black blood donors visiting the blood bank of a tertiary care university hospital between January 2019 and July 2019.
