Synthetic Cannabinoids-Related Cardiovascular Emergencies: A Review of the Literature.

Synthetic cannabinoids (SCBs) are a group of psychoactive compounds, known to cause a range of multisystem adverse events, including the cardiovascular system. The aim of this review is to provide an overview of the literature on cardiovascular emergencies associated with SCBs. A systematic search of electronic databases was conducted to identify relevant studies published between January 2010 and September 2022.

Eccentric Versus Concentric Exercises in Patients With Rheumatoid Arthritis and Rotator Cuff Tendinopathy: A Randomized Comparative Study.

Objective: To determine the efficacy of concentric vs. eccentric exercise in improving shoulder function, pain, and tendon characteristics for patients with rheumatoid arthritis and rotator cuff tendinopathy.

Methods: Forty patients with rheumatoid arthritis and rotator cuff tendinopathy were divided into either concentric or eccentric exercise groups, with 20 patients in each group.

Effect of Neural Mobilization Exercises in Patients With Low Back-Related Leg Pain With Peripheral Nerve Sensitization: A Prospective, Controlled Trial.

Objective: The aim of this study was to investigate the short-term effect of slider and tensioner exercises on pain and range of motion (ROM) of straight leg raise (SLR) and slump tests in patients with low back-related leg pain with peripheral nerve sensitization.

Methods: In this prospective, controlled trial, 51 patients with low back-related leg pain with peripheral nerve sensitization were divided into 3 treatment groups: slider (slider neural mobilization exercise + transcutaneous electric nerve stimulation [TENS]), tensioner (tensioner neural mobilization exercise + TENS), and control (only TENS). Each patient received 6 sessions over 2 weeks.

Ustekinumab dose escalation improves clinical responses in refractory Crohn's disease.

Background: Clinicians often utilize off-label dose escalation of ustekinumab (UST) in Crohn's disease (CD) patients with disease refractory to standard dosing. Previous studies report mixed results with dose escalation of UST.

Methods: A retrospective observational study of 143 adult patients with CD receiving UST over a 33-month time period was conducted.

Pediatric systemic lupus erythematosus in a single nephrology unit.

Clinical manifestations of systemic lupus erythematosus (SLE) are widely variable, and its course is unpredictable. SLE that begins in childhood has been considered more severe than SLE with onset during adulthood. Our aim was to determine the presentation and the outcome of SLE of 26 children (20 females and 6 males, with a female to male ratio of 3.

Association of postural balance and isometric muscle strength in early- and middle-school-age boys.

Objective: The purpose of this study was to evaluate the isometric muscle strength (IMS) and dynamic balance in early- and middle-school-age boys and to assess the strength of association between the dynamic balance scores and 6 different IMS indexes.

Methods: This is a cross-sectional study of a convenience sample of 94 boys who were 6 to 10 years of age and classified into an early school age (6-8 years) group (n = 50) and a middle school age (8-10 years) group (n = 44). Balance was tested using a Biodex Balance System.

Evaluation of isometric muscle strength and magnitude of hand dominance in right-handed school-age boys.

The aim of this study was to examine bilateral isometric muscle strength (IMS) in right-handed boys. To determine the association between the magnitudes of right handedness (MRH) and (a) the interside difference indexes of IMS of certain muscle categories, (b) age, and (c) some anthropometric characteristics. This was a cross-sectional study.

Fluorescence and FTIR Spectra Analysis of Trans-A₂B₂-Substituted Di- and Tetra-Phenyl Porphyrins.

A series of asymmetrically substituted free-base di- and tetra-phenylporphyrins and the associated Zn-phenylporphyrins were synthesized and studied by X-ray diffraction, NMR, infrared, electronic absorption spectra, as well as fluorescence emission spectroscopy, along with theoretical simulations of the electronic and vibration structures. The synthesis selectively afforded trans-A₂B₂ porphyrins, without scrambling observed, where the AA and BB were taken as donor- and acceptor-substituted phenyl groups. The combined results point to similar properties to symmetrically substituted porphyrins reported in the literature.

Regression of brown tumor of the maxilla in a patient with secondary hyperparathyroidism after a parathyroidectomy.

Brown tumors or osteoclastomas are erosive bony lesions arising as a complication of hyperparathyroidism. In patients with end-stage renal disease, brown tumors are uncommon skeletal manifestations that are usually seen in severe forms of secondary hyperparathyroidism. Initial treatment involves the correction of hyperparathyroidism, which usually leads to regression of the tumors.

Time-dependent density functional theory for resonant properties: resonance enhanced Raman scattering from the complex electric-dipole polarizability.

Based on resonant-convergent-and thereby complex-electric-dipole polarizabilities, formulae for differential cross sections in resonant Raman spectroscopy are presented. In absorptive regions of the spectrum, there are phase delays in the induced polarization that enter the expressions for the cross sections. The theory is exemplified by calculations employing the adiabatic time-dependent density functional theory approximation, with applications on the low-lying, dipole-allowed, electronic states of a sample of molecules, including hydrogen peroxide, pyridine, and trinitrotoluene.
