New Trends in the Treatment of Osteoporosis
1998
Osteoporosis is “a systemic disease characterized by a reduction in bone mass and a microarchitectonic alteration of the skeleton, with a consequent increase in skeleton fragility and susceptibility to fractures”, as defined by the last Consensus Development Conference1. With this definition, the alteration in skeletal structure, which is not yet easy to evaluate, becomes an important factor determining the risk of fracture of the osteoporotic patient, in addition to the bone mass, which to certain limit can be easily evaluated. This is an aspect that may create some problems at the time of taking a decision on how to proceed with a subject with decreased bone mass. Currently, the measureme…
Asymptomatic Bone Cement Pulmonary Embolism after Vertebroplasty: Case Report and Literature Review
2013
Introduction. Acrylic cement pulmonary embolism is a potentially serious complication following vertebroplasty. Case Report. A 70-year-old male patient was treated with percutaneous vertebroplasty for osteoporotic nontraumatic vertebral collapse of L5-S1. Asymptomatic pulmonary cement embolism was detected on routine postoperative chest radiogram and the patient was treated with enoxaparin, amoxicillin, and dexamethasone. At the followup CT scan no further migration of any cement material was reported; and the course was uneventful. Discussion. The frequency of local leakage of bone cement is relatively high (about 80–90%), moreover, the rate of cement leakage into the perivertebral veins (…
Fit-for-Discharge Criteria after Esophagectomy: An International Expert Delphi Consensus
2021
Summary There are no internationally recognized criteria available to determine preparedness for hospital discharge after esophagectomy. This study aims to achieve international consensus using Delphi methodology. The expert panel consisted of 40 esophageal surgeons spanning 16 countries and 4 continents. During a 3-round, web-based Delphi process, experts voted for discharge criteria using 5-point Likert scales. Data were analyzed using descriptive statistics. Consensus was reached if agreement was ≥75% in round 3. Consensus was achieved for the following basic criteria: nutritional requirements are met by oral intake of at least liquids with optional supplementary nutrition via jejunal fe…
Epidemiology and Cancer Prevention
2021
Cancer registries (CR) are essential structures for the recording of neoplasms in order to study their distribution and characteristics among a given population; this, moreover, can help in identifying possible main risk factors linked to some cancer conditions. Prevention nowadays is a fundamental key strategy for the control of neoplasms, and this is the reason why policies and screening programs should be implemented in order to raise awareness and reduce exposure to risk factors.
The use of nomograms in LDR-HDR prostate brachytherapy
2011
Purpose: The common use of nomograms in Low Dose Rate (LDR) permanent prostate brachytherapy (BT) allows to estimate the number of seeds required for an implant. Independent dosimetry verification is recommended for each clinical dosimetry in BT. Also, nomograms can be useful for dose calculation quality assurance and they could be adapt ed to High Dose Rate (HDR). This work sets nomograms for LDR and HDR prostate-BT implants, which are applied to three different institutions that use different implant techniques. Material and methods: Patients treated throughout 2010 till April 2011 were considered for this study. This exam ple was chosen to be the representative of the latest implant tech…
Factors Predisposing to Hypertension in Subjects Formerly Born Preterm: Renal Impairment, Arterial Stiffness, Endothelial Dysfunction or Something E…
2020
: Subjects formerly born preterm subsequently develop arterial - particularly isolated systolic- hypertension more frequently than their peers born at term. : Numerous factors may influence this predisposition, including an incomplete nephrogenesis, implying the presence of kidneys with a reduced number of nephrons and consequent reduction in haematic filtration, increased sodium absorption and activation of renin-angiotensin-aldosterone system, increased arterial rigidity produced by an elastin deficiency previously observed in anatomic specimens of human immature aorta, and reduced endothelial nitric oxide excretion, due to high blood levels of ADMA, a strong direct inhibitor of nitric o…
Combining Quantitative and Qualitative Data in the Study of Feeding Behavior in Male Wistar Rats
2019
The first step in a behavioral study is represented by the organization of a suitable ethogram, that is, a formal description of individual components of the behavior. Then, each component of such a behavioral repertoire can be quantified (e.g., how many times it occurs, its duration, percent distribution, latency, etc.). However, it is our contention that the possibility to describe the behavior of a living being by means of hundreds or even thousands of numbers concerning isolated components, disjointed from the comprehensive behavioral architecture, does not imply the possibility to use those numbers to reconstruct the meaning of behavior. Such a level of comprehension requires a qualita…
Effectiveness of a Program Combining Strengthening, Stretching, and Aerobic Training Exercises in a Standing versus a Sitting Position in Overweight …
2020
There is an increasing incidence, prevalence, and burden of knee osteoarthritis due to a global increase in obesity and an aging population. The aim of the present study was to compare the effectiveness of the addition of aerobic exercises performed in an unloaded or loaded position to a conventional exercise program in overweight subjects with knee osteoarthritis. Twenty-four subjects were randomly allocated to receive 36 sessions of 30-min duration of either sitting aerobic exercises (experimental group) or standing aerobic exercises (control group). Pain intensity, knee disability, and quality-of-life data were collected at baseline and at 12, 24, and 36 sessions. Generalized linear mixe…
A Multimodal Speech-Gesture Training Intervention for Patients With Schizophrenia and Its Neural Underpinnings – the Study Protocol of a Randomized C…
2020
Dysfunctional social communication is one of the most stable characteristics in patients with schizophrenia that also affects quality of life. Interpreting abstract speech and integrating nonverbal modalities is particularly affected. Considering the impact of communication on social life but failure to treat communication dysfunctions with usual treatment, we will investigate the possibility to improve verbal and non-verbal communication in schizophrenia by applying a multimodal speech-gesture training (MSG training). Here we describe the newly developed MSG training program and the study design for the first clinical investigation. The intervention contains perceptive rating (match/mismat…
Thrombendarteriektomie bei chronischer thromboembolischer pulmonaler Hypertonie: Hämodynamik und Rechtsherzfunktion im Langzeitverlauf
2008
OBJECTIVE To find out whether pulmonary thromboendarterectomy (PTE) can achieve lasting reduction of pulmonary vascular resistance in patients with pulmonary arterial hypertension due to chronic thromboembolism. PATIENTS AND METHODS 45 patients (25 women, 20 men; mean age 45 +/- 24 [19-67] years) were re-investigated a mean of 21 (13-32) months after successful PTE. Two patients had then been in New York Heart Association (NYHA) stage II, 26 in stage III, and 17 in stage IV. In addition to clinical examination and chest radiogram 36 patients had right heart catheterization, 28 pulmonary angiography and 44 echocardiography. RESULTS Definite improvement of symptoms had occurred in all. 34 wer…
