Association of physical activity and trajectories of physical activity with cardiovascular disease.

Introduction: Prolonged sedentary life existence is associated with increased incidence of cardiovascular disease (CVD), coronary heart disease (CHD), obesity, type 2 diabetes mellitus (T2DM), hypertension, heart failure (HF), and all-cause mortality. On the contrary, regular exercise is known from antiquity to be associated with beneficial cardiovascular (CV) effects and decreased mortality.

Areas Covered: The cardiovascular (CV) benefits of exercise have been confirmed by many studies, but the trajectories of the different modes of PA are not well recognized.

Dorsoradial Capsulodesis for Stage I Trapeziometacarpal Joint Arthrosis.

Background: Thumb trapeziometacarpal (TM) joint arthrosis is a common cause of thumb pain, which adversely affects hand function. Early arthrosis is characterized by capsular laxity, painful pinch and grip, and physical findings of joint tenderness and laxity. Dorsoradial capsulodesis (DRC) is a surgical technique used to stabilize the TM joint and treat early-stage arthrosis.

Management of Acute Idiopathic (Viral) Pericarditis in the Emergency Department: A Review for the Nursing Professional.

Acute pericarditis is an inflammatory disorder that contributes to chest pain admissions in the emergency department (ED). Nursing professionals can play a vital role in the differential, triage and management of acute pericarditis in the ED. First-line pharmacotherapy to specifically treat acute pericarditis of viral or idiopathic origin is paramount in improving patients' quality of life and reducing the risk of further recurrences of pericarditis and consists of combination therapy with aspirin (acetylsalicylic acid [ASA]) or a nonsteroidal anti-inflammatory drug (NSAID), in combination with colchicine.

Two-Year Outcomes with a Magnetically Levitated Cardiac Pump in Heart Failure.

Background: In an early analysis of this trial, use of a magnetically levitated centrifugal continuous-flow circulatory pump was found to improve clinical outcomes, as compared with a mechanical-bearing axial continuous-flow pump, at 6 months in patients with advanced heart failure.

Methods: In a randomized noninferiority and superiority trial, we compared the centrifugal-flow pump with the axial-flow pump in patients with advanced heart failure, irrespective of the intended goal of support (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke (with disabling stroke indicated by a modified Rankin score of >3; scores range from 0 to 6, with higher scores indicating more severe disability) or survival free of reoperation to replace or remove a malfunctioning device.

Extensor Tendon Instability Due to Sagittal Band Injury in a Martial Arts Athlete: A Case Report.

A Taekwondo participant sustained a hand injury from punching an opponent that resulted in painful instability of the ring finger extensor digitorum communis tendon due to sagittal band damage. His symptoms resolved after reconstructive surgery on the sagittal band (SB) with stabilization of the extensor tendon over the metacarpophalangeal joint.

A Fully Magnetically Levitated Circulatory Pump for Advanced Heart Failure.

Background: Continuous-flow left ventricular assist systems increase the rate of survival among patients with advanced heart failure but are associated with the development of pump thrombosis. We investigated the effects of a new magnetically levitated centrifugal continuous-flow pump that was engineered to avert thrombosis.

Methods: We randomly assigned patients with advanced heart failure to receive either the new centrifugal continuous-flow pump or a commercially available axial continuous-flow pump.

Prevention of hypophosphatemia after burn injury with a protocol for continuous, preemptive repletion.

Severe burn injury has been shown to result in hypophosphatemia. Hypophosphatemia can cause cardiac, hematologic, immunologic, and neuromuscular dysfunction. This study compares serum phosphate levels and outcomes in patients who were administered a continuous, preemptive phosphate repletion protocol vs those who only received phosphate supplementation after they developed hypophosphatemia.

Extensor tendon reconstruction for zones II and IV using local tendon flap: a cadaver study.

Purpose: To assess the feasibility of reconstructing extensor tendon segmental defects in zones II (over the middle phalanx) and IV (over the proximal phalanx) using local tendon flaps (LTFs), explore in these 2 zones the anatomical constraints that limit the use of the LTF as regards the maximum defect that could be reconstructed, and compare this flap with distant tendon grafts (DTG) reconstruction for similar size defects.

Methods: We dissected 33 fresh-frozen cadaver extensor tendons from the fingers of 9 fresh-frozen cadaver forearms. A 0.

Closing wedge osteotomy of abnormal middle phalanx for clinodactyly.

Purpose: To report a series of clinodactyly patients to report clinical and radiographic outcomes after closing wedge osteotomy and K-wire fixation of abnormal middle phalanges.

Methods: Twenty-five fingers from 17 patients were included in the study. All patients had more than 25 degrees of angulation and were treated with closing wedge osteotomy.

Complex dorsal metacarpophalangeal joint dislocation caused by interosseous tendon entrapment: case report.

We report a patient with open complex, dorsal metacarpophalangeal joint dislocation of the index finger with interposition of the first dorsal interosseous tendon and the transverse ligament of the palmar aponeurosis. To our knowledge, entrapment of the first dorsal interosseous tendon has not been reported to be the cause of irreducible dislocation of the metacarpophalangeal joint.

Non-Dupuytren's disease of the palmar fascia.

The typical Dupuytren's disease patient is of Northern European descent with bilateral progressive multiple digital contractures and is genetically predisposed, with a family history. Palmar fascial proliferations sometimes present as a different entity without the typical Dupuytren's disease characteristics. We identified 39 patients (20 women and 19 men) over a 4-year period with "Non-Dupuytren's palmar fascial disease", with unilateral involvement, without family history or ectopic manifestations.

The terminal tendon of the digital extensor mechanism: Part II, kinematic study.

Purpose: To conduct kinematic analyses of both intact and sectioned terminal tendon (TT) of multiple fingers in the hand.

Methods: The TTs of 36 fresh-frozen cadaveric digits were used in this study. TT excursion was assessed along with the influence on proximal joint motion.

Intravenous catheter complications in the hand and forearm.

Background: We studied the complications of peripheral intravenous (i.v.) catheters in the hand and forearm in a teaching hospital over a 3-year period.

Raymond Curtis: the prototypical hand surgeon.

Raymond Curtis was an unusual man who lived in unusual times and made unusual contributions. He promoted hand surgery, a specialty that was little known in his early time. He educated many surgeons in the science, art, and philosophy of hand surgery.

Radiographic analysis of pisotriquetral joint and pisiform motion.

We evaluated 45 wrists of normal volunteers fluoroscopically (15) and radiographically (30) to determine the optimal radiographic technique for profiling the pisotriquetral (PT) joint and to assess the pisiform motion. Real-time fluoroscopy showed that 4 views are necessary for optimal PT joint and pisiform visualization: wrist neutral/30 degrees forearm supination, wrist extension/30 degrees forearm supination, and active plus passive wrist flexion/45 degrees forearm supination with thumb abduction. Excursion percentage of the PT articular surface apposition on video imaging occurred 10% proximally in neutral, 20% distally in extension, and 40% proximally in flexion.

Dupuytren's cord involving the septa of Legueu and Juvara: a case report.

A patient with Dupuytren's disease with involvement of the palmar fascial complex and digital contracture is described. A vertical cord had developed in the transverse ligament of the palmar aponeurosis fibers and the underlying septa of Legueu and Juvara. The cord was composed of a pretendinous band, transverse ligament of the palmar aponeurosis, and septum of Legueu and Juvara.
