Disentangling the veil line for Brazilian biodiversity: An overview from two long-term research programs reveals huge gaps in ecological data reporting.

The lack of synthesized information regarding biodiversity is a major problem among researchers, leading to a pervasive cycle where ecologists make field campaigns to collect information that already exists and yet has not been made available for a broader audience. This problem leads to long-lasting effects in public policies such as spending money multiple times to conduct similar studies in the same area. We aim to identify this knowledge gap by synthesizing information available regarding two Brazilian long-term biodiversity programs and the metadata generated by them.

Unilateral Sacral Erector Spinae Plane Block for Thigh Amputation: Case Report.

Selection of anesthetic technique for thigh amputation is complicated by patients' comorbid conditions. The sacral erector spinae plane block (ESPB) is an emerging technique with potential as a primary anesthetic for thigh amputation. We detail a case involving a 79-year-old undergoing thigh amputation, where sacral ESPB proved insufficient, prompting a shift to spinal anesthesia.

Arteriovenous anastomosis learning curve using low cost simulator.

Background: In order to reduce difficulties with learning surgical techniques, supplementary tools for training were developed. This paper describes the learning curve followed by student volunteer research subjects who used an alternative model for practicing vascular anastomosis.

Objectives: To evaluate the vascular anastomosis technique learning curve and development of manual skills using a low-cost experimental model.

Altered Venous Function during Long-Duration Spaceflights.

Venous adaptation to microgravity, associated with cardiovascular deconditioning, may contribute to orthostatic intolerance following spaceflight. The aim of this study was to analyze the main parameters of venous hemodynamics with long-duration spaceflight. Venous plethysmography was performed on 24 cosmonauts before, during, and after spaceflights aboard the International Space Station.

Lumbar spinal anesthesia with cervical nociceptive blockade. Critical review of a series of 1,330 procedures.

Background And Objectives: The manufacture of minimally traumatic needles and synthesis of pharmacological adjuncts with safe and effective action on inhibitory and neuromodulatory synapses distributed along the nociceptive pathways were crucial for a new expansion phase of spinal anesthesia. The objectives of this paper are present our clinical experience with 1330 lumbar spinal anesthesia performed with purposeful nociceptive blockade of the thoracic and cervical spinal nerves corresponding to dermatomes C4 or C3; warn about the method pathophysiological risks, and emphasize preventive standards for the safe application of the technique.

Content: Review of the historical background and anatomical spinal anesthesia with cervical levels of analgesia.

[Vascular rehabilitation in patients with peripheral arterial disease].

Lower limb peripheral arterial disease (PAD) is a frequent debilitating disease associated with a high morbidity and mortality rate. The benefit of rehabilitation in PAD patients has been largely demonstrated, both for patients that undergo amputation, and for patients with claudication. In these latter patients, rehabilitation programs rely on a variety of additional techniques or tools, among which: stretching, specific muscle proprioception, walking and a variety of other physical activities, exercise or situations adapted to community life, lower limb and respiratory physiotherapy, patient's education, support for smoking cessation and healthy nutrition, social support, etc.

Relationship between breast- and bottle-feeding and non-nutritive sucking habits.

Purpose: The objective of the present study was to assess the persistence of non-nutritive sucking habits and its relationship with breastfeeding, as well as to establish the influence of sociodemographic factors on these habits among children aged 3 to 5 years.

Materials And Methods: A case-control study was conducted with 1107 children from public and private daycare centres in Natal, Brazil: 450 in the case group (312 pacifier suckers and 138 thumb suckers) and 657 in the control group (habit-free). Data regarding sociodemographic conditions and duration of breastfeeding were obtained using a structured questionnaire.

[Reflections around the performance of community health agents in oral health strategies].

The Community Health Agent (CHA) has traditionally been linked to doctors and nurses, being considered exclusive 'property' of these professionals. Historically, oral health tended to operate isolated, disconnecting the mouth from the rest of the body and the individual from his environment. The Family Health Program (FHP) points to important changes in the organization of services as well as in the work process.
