Diabetes and Quality of Life: Initial Approach to Depression, Physical Activity, and Sexual Dysfunction.

The different aspects that contribute to quality of life in patients with diabetes mellitus, such as mood, are of great importance for the treatment of this disease. These aspects not only influence the well-being of patients but also influence treatment adherence, therefore affecting the course of the disease. A panel of experts from Argentina, Chile, and Uruguay performed a review of the main aspects affecting quality of life in patients with diabetes: physical activity, mood disorders, and sexual activity.

Association between socioeconomic status, type 2 diabetes and its chronic complications in Argentina.

Aim: To compare the socioeconomic status (SES) of people with type 2 diabetes (T2DM) in Argentina (Córdoba) with and without major chronic complications of diabetes, with that recorded in persons without diabetes matched by age and gender.

Methods: For this descriptive and analytic case-control study, potential candidates were identified from the electronic records of one institution of the Social Security System of the city of Córdoba. We identified and recruited 387 persons each with T2DM with or without chronic complications and 774 gender- and age-matched persons without T2DM (recruitment rate, 83%).

A literature review of intercostal-to-musculocutaneous-nerve transfers in brachial plexus injury patients: Does body mass index influence results in Eastern versus Western countries?

Background: A wide range of results have appeared in the literature for intercostal nerve transfers in brachial plexus patients. Oriental countries generally have a lower body mass index (BMI) than their occidental counterparts. We analyzed published series of intercostal nerve transfers for elbow reinnervation to determine if a difference in outcomes exists between Eastern and Western series that could be inversely related to BMI.

Capsular grafts and flaps in immediate prosthetic breast reconstruction.

Background: Patients with previously augmented breasts and a diagnosis of breast cancer who are candidates for immediate prosthetic reconstruction can benefit from capsular tissues used for splinting the position of the pectoralis major muscle.

Methods: A retrospective clinical review of patients with previously augmented breasts who are undergoing mastectomy and immediate prosthetic reconstruction with capsular tissues was undertaken. The bottom of the periprosthetic capsule was tailored in a novel and versatile fashion as grafts or flaps and used as a sling between the pectoralis major and the inframammary fold.

Cluster B personality symptoms in persons at genetic risk for schizophrenia are associated with social competence and activation of the right temporo-parietal junction during emotion processing.

Personality disorders are common in nonpsychotic siblings of patients with schizophrenia, and some personality traits in this group may be associated with an increased risk for full-blown psychosis. We sought to establish if faulty right-hemisphere activation induced by social cognitive tasks, as previously described in patients with schizophrenia, is associated with specific personality symptoms in their unaffected siblings. We observed that cluster B personality symptoms in this group were inversely related to activation in the right temporo parietal junction (rTPJ, a structure critical in social cognitive processing) in response to a basic emotion processing task and also to social competence, whereas in contrast to our initial hypothesis, cluster A traits were not associated with right hemisphere activation during emotion processing or with social competence.

Association between chronic blood pressure changes and development of Alzheimer's disease.

Epidemiological studies suggest an association between chronic blood pressure (BP) changes and Alzheimer's disease (AD). In particular, there is growing evidence that hypertensive people that do not have their BP adequately treated and controlled in midlife are more likely to develop AD in late-life. It has been hypothesized that cerebrovascular disease is a common pathway which connects hypertension and AD in individuals with apolipoprotein E genotype through brain hypoperfusion and hypoxia.

Upper brachial plexus injuries: grafts vs ulnar fascicle transfer to restore biceps muscle function.

Background: Nerve transfers or graft repairs in upper brachial plexus palsies are 2 available options for elbow flexion recovery.

Objective: To assess outcomes of biceps muscle strength when treated either by grafts or nerve transfer.

Methods: A standard supraclavicular approach was performed in all patients.

Bell's palsy and partial hypoglossal to facial nerve transfer: Case presentation and literature review.

Background: Idiopathic facial nerve palsy (Bell's palsy) is a very common condition that affects active population. Despite its generally benign course, a minority of patients can remain with permanent and severe sequelae, including facial palsy or dyskinesia. Hypoglossal to facial nerve anastomosis is rarely used to reinnervate the mimic muscle in these patients.

Exposure of the sciatic nerve in the gluteal region without sectioning the gluteus maximus: Analysis of a series of 18 cases.

Background: Dissecting through the gluteus maximus muscle by splitting its fibers, instead of complete sectioning of the muscle, is faster, involves less damage to tissues, and diminishes recovery time. The objective of the current paper is to present a clinical series of sciatic nerve lesions where the nerve was sufficiently exposed via the transgluteal approach.

Methods: We retrospectively selected 18 traumatic sciatic nerve lesions within the buttock, operated upon from January 2005 to December 2009, with a minimum follow-up of 2 years.

Dynamics of adrenal steroids are related to variations in Th1 and Treg populations during Mycobacterium tuberculosis infection in HIV positive persons.

Tuberculosis (TB) remains the most frequent cause of illness and death from an infectious agent, and its interaction with HIV has devastating effects. We determined plasma levels of dehydroepiandrosterone (DHEA), its circulating form DHEA-suphate (DHEA-s) and cortisol in different stages of M. tuberculosis infection, and explored their role on the Th1 and Treg populations during different scenarios of HIV-TB coinfection, including the immune reconstitution inflammatory syndrome (IRIS), a condition related to antiretroviral treatment.

Transfer of flexor carpi ulnaris branches to selectively restore AIN function in median nerve sections: Anatomical feasibility study and case report.

Background: In recent years, distal nerve transfers have become a valid tool for nerve reconstruction. Though grafts remain the gold standard for proximal median nerve injuries, a new distal transfer of flexor carpi ulnaris branches of the ulnar nerve to selectively restore anterior interosseous nerve function, concomitant with median nerve graft repair, could enhance outcomes. The objective of this paper is to anatomically analyze a technique to selectively reinnervate the thumb and index flexors.

Use of long autologous nerve grafts in brachial plexus reconstruction: factors that affect the outcome.

Background: Using grafts directed to distal targets in brachial plexus reconstruction has the advantage over proximal targets of avoiding axonal dispersion. A long graft (more than 10 cm) is needed to reach most distal targets. The objective of this article is to identify factors associated with good versus poor outcomes in a clinical series of long grafts used for distal brachial plexus reconstruction.

Striatal gating through up states and oscillations in the basal ganglia: Implications for Parkinson's disease.

Up states are a hallmark of striatal physiology. Spontaneous activity in the thalamo-cortical network drives robust plateau depolarizations in the medium spiny projection neurons of the striatum. Medium spiny neuron firing is only possible during up states and is very tightly regulated by dopamine and NMDA receptors.

Exposure of the sciatic nerve in the gluteal region without sectioning the gluteus maximus: an anatomical and microsurgical study.

Background: Complete sectioning of the gluteus maximus muscle is an extensive procedure when approaching the sciatic nerve in the buttock, resulting in significant morbidity and a prolonged postoperative recovery period. By contrast, dissecting through the muscle by splitting its fibers is faster, involves less damage to tissues and diminishes recovery time. The objective of the present work was to perform a cadaveric study to obtain measurements of the maximum, minimum and mean exposure that this minimally invasive approach can offer.

Establishing targets for hypertension control in patients with comorbidities.

Most current guidelines recommend tighter blood pressure (BP) control in hypertensive patients with comorbidities. These recommendations are based on epidemiologic data indicating that cardiovascular risk increases at lower BP levels in hypertensive patients with comorbidities than in those without comorbidities. Hypertension guidelines usually reflect outcomes from previous studies, but current recommendations for patients with comorbidities have preceded the evidence.

Effects of blood pressure changes on Alzheimer's disease.

Alzheimer's disease is the most frequent cause of dementia. Whereas other major causes of death have been decreasing, the number of deaths due to Alzheimer's disease is rising. As there is no cure for this type of dementia at present, preventive measures have assumed great importance.

New method of tunnelling for omental transposition in the treatment of a complex radionecrotic groin ulcer.

Omental transposition is often used for reconstruction of soft tissue in the groin. However, the potential for incisional hernia is a relative contraindication. We report the cure of a groin ulcer with omental transposition using a new method of tunnelling to avoid herniation.

Argentine valuation of the EQ-5D health states.

Objective: To develop a set of health state values based on EuroQol EQ-5D instrument for the Argentine general population.

Methods: Consecutive subjects attending six primary care centers in Argentina were selected based on quota sampling and were interviewed using the EuroQol Group protocol for measurement and valuation of health studies. Initially, the respondents were randomly assigned a unique card set; however, to improve efficiency, the subjects were later randomly assigned to one of three fixed sets of EQ-5D states.

Role of transforming growth factor beta in the regulation of thyroid function and growth.

Transforming growth factor beta (TGF-beta) exists in nature as three isoforms. They exert their effects by binding to a type II receptor located at the cell membrane. The TGF-beta-type II receptor complex then recruits type I receptor, and this new complex stimulates the phosphorylation of Smads 2 and 3, which are subsequently transferred to the nucleus, where they regulate gene transcription.
