Comparison the Effect of Rehabilitation at Home and Outpatient Physiotherapy after Total Knee Arthroplasty Surgery on Quality of Life and Knee Function: A Clinical Trial Study.

Background: Primary total knee arthroplasty (TKA) is an effective procedure to better function and relief the pain in advanced osteoarthritis patients. This study aimed to evaluate the effectiveness and safety of outpatient clinic-based setting of physiotherapy versus home-based rehabilitation (HBR) for functional recovery immediately after primary TKA procedure.

Materials And Methods: This randomized clinical trial study was conducted on patients underwent TKA in 2021-2022.

Correlation of rib fracture patterns with abdominal solid organ injury: A retrospective observational cohort study.

Purpose: Rib fractures are one of the most common causes of morbidity and mortality and are associated with abdominal solid organ injury (ASOI). The purpose of this study was to investigate the correlation of ASOI with the number, location, and involved segments of rib fracture(s) in blunt chest trauma.

Methods: This retrospective cohort study was conducted on patients with blunt chest trauma over the age of 15 years, who were hospitalized with the diagnosis of rib fractures from July 2015 to September 2020.

No difference in union and recurrence rate between iliac crest autograft versus allograft following medial opening wedge high tibial osteotomy: a randomized controlled trial.

Purpose: Using iliac crest autograft has been considered as gold standard for gap filling in medial opening wedge high tibial osteotomy (MOW-HTO) but is associated with donor site morbidity and pain. The purpose of this study was to compare the results of the use of iliac crest autograft versus allograft from the same anatomic site in terms of union and recurrence.

Methods: Forty-six patients with genovarum with or without medial compartment osteoarthritis were enrolled based on specific inclusion and exclusion criteria and were randomly assigned into two groups.

Combination adjunctive nebulized furosemide and salbutamol versus single agent therapy in COPD patients: A randomized controlled trial.

Background: COPD patients often require multiple therapies to enhance their lung function and reduce their symptoms in exacerbations. This study aimed to investigate the relative effects of combination adjunctive nebulized furosemide and salbutamol therapy versus single agent treatment in COPD patients.

Methods: Sixty-nine COPD patients were randomly divided into two groups.

Glenohumeral Joint Kinematics following Clavicular Fracture and Repairs.

Background: The purpose of this biomechanical study was to determine the effect of shortened clavicle malunion on the center of rotation of the glenohumeral (GH) joint, and the capacity of repair to restore baseline kinematics.

Methods: Six shoulders underwent automated abduction (ABD) and abbreviated throwing motion (ATM) using a 7-DoF automated upper extremity testing system in combination with an infrared motion capture system to measure the center of rotation of the GH joint. ATM was defined as pure lateral abduction and late cocking phase to the end of acceleration.

Influence of disruption of the acromioclavicular and coracoclavicular ligaments on glenohumeral motion: a kinematic evaluation.

Background: Changes to the integrity of the acromioclavicular (AC) joint impact scapulothoracic and clavicular kinematics. AC ligaments provide anterior-posterior stability, while the coracoclavicular (CC) ligaments provide superior-inferior stability and a restraint to scapular internal rotation. The purpose of this cadaveric study was to describe the effect of sequential AC and CC sectioning on glenohumeral (GH) kinematics during abduction (ABD) of the arm.

Multistable Shape-Reconfigurable Architected Materials.

Multistable shape-reconfigurable architected materials encompassing living hinges and enabling combinations of high strength, high volumetric change, and complex shape-morphing patterns are introduced. Analytical and numerical investigations, validated by experiments, are performed to characterize the mechanical behavior of the proposed materials. The proposed architected materials can be constructed from virtually any base material, at any length scale and dimensionality.

The effect of the rotator interval on glenohumeral kinematics during abduction.

Background: The rotator interval (RI) has been exploited as a potentially benign point of entry into the glenohumeral (GH) joint. Bounded by the supraspinatus, subscapularis and coracoid process of the scapula, the RI is believed to be important in the shoulder's soft tissue balancing and function. However, the role of the RI in shoulder kinematics is not fully understood.

Optimal fractal-like hierarchical honeycombs.

Hexagonal honeycomb structures are known for their high strength and low weight. We construct a new class of fractal-appearing cellular metamaterials by replacing each three-edge vertex of a base hexagonal network with a smaller hexagon and iterating this process. The mechanical properties of the structure after different orders of the iteration are optimized.

Buckling of regular, chiral and hierarchical honeycombs under a general macroscopic stress state.

An approach to obtain analytical closed-form expressions for the macroscopic 'buckling strength' of various two-dimensional cellular structures is presented. The method is based on classical beam-column end-moment behaviour expressed in a matrix form. It is applied to sample honeycombs with square, triangular and hexagonal unit cells to determine their buckling strength under a general macroscopic in-plane stress state.

Acceptable outcome following resection of bilateral large popliteal space heterotopic ossification masses in a spinal cord injured patient: a case report.

Spinal cord injury is a well-known predisposing factor for development of heterotopic ossification around the joints especially hip and elbow. Heterotopic ossification about the knee is usually located medially, laterally or anteriorly; besides, the knee is generally fixed in flexion. There are only a few reports of heterotopic bone formation at the posterior aspect of the knee (popliteal space) and fixation of both knees in extension; so, there is little experience in operative management of such a problem.

Gastrointestinal complications in two patients with common variable immunodeficiency.

Common variable immunodeficiency (CVID) is a primary immunodeficiency disease characterized by hypogammaglobulinemia and recurrent bacterial infections especially in respiratory and gastrointestinal systems. We present here 2 cases of CVID with gastrointestinal complications.Case 1 is a 25-year-old man with a history of chronic diarrhoea from childhood.

Relationship between serum alanine aminotransferase levels and liver histology in chronic hepatitis C-infected patients.

Background: The efficacy of serum alanine aminotransferase (ALT) levels in predicting the severity of hepatitis C virus (HCV) infection is unclear.

Objective: To compare histologic scoring of liver pathology in patients with chronic HCV infection with normal or elevated serum ALT.

Methods: Liver biopsies were performed in patients with HCV infection and either normal (n=40) or elevated (n=76) serum ALT levels, and scored for activity and fibrosis using the modified histological activity index.

Effects of indomethacin on viral replication markers in asymptomatic carriers of hepatitis B: a randomized, placebo-controlled trial.

Objectives: Previous studies have suggested some benefits of nonsteroidal antiinflammatory drugs (NSAIDs) use in patients with chronic viral hepatitis. We evaluated potential effects of indomethacin in asymptomatic carriers of hepatitis B surface antigen (HBsAg).

Design: Randomized, placebo-controlled, double-masked clinical trial.

Clinical course of ulcerative colitis in patients with and without primary sclerosing cholangitis.

Background And Aim: We noticed in our practice that patients with ulcerative colitis (UC) who have developed primary sclerosing cholangitis (PSC) experience a milder course of colonic disease. Our objective in this study was to define whether or not there is any difference between UC activity and its course in patients with and without PSC.

Methods: Nineteen patients with UC and PSC (eight male, mean age 25 years) were enrolled.

Clinical and histological features of nonalcoholic steatohepatitis in Iranian patients.

Background: Although several studies have been performed on risk factors and natural course of NASH, it seems that NASH tends to be more than a disease confined to strict boundaries. The objective of this study was to assess the clinical and paraclinical features and risk factors for non-alcoholic steatohepatitis (NASH) patients in an Iranian population

Methods: Patients with histologically confirmed NASH who had elevated liver aminotransaminases, negative serologic markers of viral or autoimmune hepatitis and no findings in favor of metabolic liver disease were enrolled. A careful history was taken regarding alcohol intake.
