Reinventing Patient Support and Continuity of Care Using Innovative Physician-staffed Hotline: More than 60,000 Patients Served Across 15 Medical and Surgical Specialties During the First Wave of COVID-19 Lockdown in Qatar.

Rising disease prevalence early during the COVID-19 pandemic in the State of Qatar led to stoppage of all non-emergency health care services. To maintain continuity of care and information exchanges for non-emergency patients, a physician-operated telephone hotline was set up that involved triage followed by immediate consultation with a specialized physician. We describe the initiation and evaluate the operations of the Urgent Consultation Centre (UCC) hotline manned by 150 physicians and aimed at urgent non-life-threatening consultations at Hamad Medical Corporation, the public health provider in Qatar.

Reverse shoulder arthroplasty for deltoid-deficient shoulder following latissimus dorsi flap transfer. Case report.

Introduction: The usual indication for reverse shoulder arthroplasty is glenohumeral arthritis with inadequate rotator cuff and intact deltoid muscle. We report here a case of reverse shoulder arthroplasty using a lattisimus dorsi flap in a patient with deltoid-deficient shoulder following a gunshot injury.

Presentation Of The Case: The patient was an otherwise healthy 51-year-old male with a history of gunshot injury of the left shoulder 2006.

Effect of aniline coupling on kinetic and thermodynamic properties of Fusarium solani glucoamylase.

Purified glucoamylase (GA) from Fusarium solani was chemically modified by cross-linking with aniline hydrochloride in the presence of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) for 1 [aniline-coupled glucoamylase-1 (ACG-1)], 7 (ACG-7), and 13 min (ACG-13). The aniline coupling of GA had a profound enhancing effect on temperature, pH optima, and pK (a)'s of active site residues. The specificity constants (K (cat)/K (m)) of native, ACG-1, ACG-7, and ACG-13 were 136, 244, 262, and 208 at 55 degrees C for starch, respectively.
