Refracture following vertebral fragility fracture when bone fragility is not recognized: summarizing findings from comparator arms of randomized clinical trials.

PURPOSE: Since vertebral fragility fractures (VFFs) might increase the risk of subsequent fractures, we evaluated the incidence rate and the refracture risk of subsequent vertebral and non-vertebral fragility fractures (nVFFs) in untreated patients with a previous VFF. METHODS: We systematically searched PubMed, Embase, and Cochrane Library up to February 2022 for randomized clinical trials (RCTs) that analyzed the occurrence of subsequent fractures in untreated patients with prior VFFs. Two authors independently extracted data and appraised the risk of bias in the selected studies. Primary outcomes were subsequent VFFs, while secondary outcomes were further nVFFs. The outcome of refracture within ≥ 2 years after the index fracture was measured as (i) rate, expressed per 100 person-years (PYs), and (ii) risk, expressed in percentage. RESULTS: Forty RCTs met our inclusion criteria, ranging from medium to high quality. Among untreated patients with prior VFFs, the rate of subsequent VFFs and nVFFs was 12 [95% confidence interval (CI) 9-16] and 6 (95% CI 5-8%) per 100 PYs, respectively. The higher the number of previous VFFs, the higher the incidence. Moreover, the risk of VFFs and nVFFs increased within 2 (16.6% and 8%) and 4 years (35.1% and 17.4%) based on the index VFF. CONCLUSION: The highest risk of subsequent VFFs or nVFFs was already detected within 2 years following the initial VFF. Thus, prompt interventions should be designed to improve the detection and treatment of VFFs, aiming to reduce the risk of future FFs and properly implement secondary preventive measures.

The integrated structure of care: evidence for the efficacy of models of clinical governance in the prevention of fragility fractures after recent sentinel fracture after the age of 50 years.

Randomized clinical trials and observational studies on the implementation of clinical governance models, in patients who had experienced a fragility fracture, were examined. Literature was systematically reviewed and summarized by a panel of experts who formulated recommendations for the Italian guideline. PURPOSE: After experiencing a fracture, several strategies may be adopted to reduce the risk of recurrent fragility fractures and associated morbidity and mortality. Clinical governance models, such as the fracture liaison service (FLS), have been introduced for the identification, treatment, and monitoring of patients with secondary fragility fractures. A systematic review was conducted to evaluate the association between multidisciplinary care systems and several outcomes in patients with a fragility fracture in the context of the development of the Italian Guidelines. METHODS: PubMed, Embase, and the Cochrane Library were investigated up to December 2020 to update the search of the Scottish Intercollegiate Guidelines Network. Randomized clinical trials (RCTs) and observational studies that analyzed clinical governance models in patients who had experienced a fragility fracture were eligible. Three authors independently extracted data and appraised the risk of bias in the included studies. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Effect sizes were pooled in a meta-analysis using random-effects models. Primary outcomes were bone mineral density values, antiosteoporotic therapy initiation, adherence to antiosteoporotic medications, subsequent fracture, and mortality risk, while secondary outcomes were quality of life and physical performance. RESULTS: Fifteen RCTs and 62 observational studies, ranging from very low to low quality for bone mineral density values, antiosteoporotic initiation, adherence to antiosteoporotic medications, subsequent fracture, mortality, met our inclusion criteria. The implementation of clinical governance models compared to their pre-implementation or standard care/non-attenders significantly improved BMD testing rate, and increased the number of patients who initiated antiosteoporotic therapy and enhanced their adherence to the medications. Moreover, the treatment by clinical governance model respect to standard care/non-attenders significantly reduced the risk of subsequent fracture and mortality. The integrated structure of care enhanced the quality of life and physical function among patients with fragility fractures. CONCLUSIONS: Based on our findings, clinicians should promote the management of patients experiencing a fragility fracture through structured and integrated models of care. The task force has formulated appropriate recommendations on the implementation of multidisciplinary care systems in patients with, or at risk of, fragility fractures.

A systematic review on the performance of fracture risk assessment tools: FRAX, DeFRA, FRA-HS.

PURPOSE: Preventing fragility fractures by treating osteoporosis may reduce disability and mortality worldwide. Algorithms combining clinical risk factors with bone mineral density have been developed to better estimate fracture risk and possible treatment thresholds. This systematic review supported panel members of the Italian Fragility Fracture Guidelines in recommending the use of best-performant tool. The clinical performance of the three most used fracture risk assessment tools (DeFRA, FRAX, and FRA-HS) was assessed in at-risk patients. METHODS: PubMed, Embase, and Cochrane Library were searched till December 2020 for studies investigating risk assessment tools for predicting major osteoporotic or hip fractures in patients with osteoporosis or fragility fractures. Sensitivity (Sn), specificity (Sp), and areas under the curve (AUCs) were evaluated for all tools at different thresholds. Quality assessment was performed using the Quality Assessment of Diagnostic Accuracy Studies-2; certainty of evidence (CoE) was evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Forty-three articles were considered (40, 1, and 2 for FRAX, FRA-HS, and DeFRA, respectively), with the CoE ranging from very low to high quality. A reduction of Sn and increase of Sp for major osteoporotic fractures were observed among women and the entire population with cut-off augmentation. No significant differences were found on comparing FRAX to DeFRA in women (AUC 59-88% vs. 74%) and diabetics (AUC 73% vs. 89%). FRAX demonstrated non-significantly better discriminatory power than FRA-HS among men. CONCLUSION: The task force formulated appropriate recommendations on the use of any fracture risk assessment tools in patients with or at risk of fragility fractures, since no statistically significant differences emerged across different prediction tools.

Prevention and protection measures of healthcare workers exposed to SARS-CoV-2 in a university hospital in Bari, Apulia, Southern Italy.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-related infection has a major impact on public health, and healthcare workers (HCWs) are exposed to high biological risk. This paper describes the prevention procedures introduced at the University Hospital of Bari, Italy to reduce the risk to HCWs, consisting of enhanced preventive measures and activation of a report system to collect HCWs' contacts. Twenty-three confirmed cases of infection (0.4% of all HCWs) were reported in the 30-day observation period following implementation of the protocol. This shows that correct management of HCWs' contacts is essential to avoid nosocomial clusters.

Malignant mesothelioma in construction workers: the Apulia regional mesothelioma register, Southern Italy.

OBJECTIVE: Asbestos was widely used in construction in both a friable and a compact form until the 1990s, before its use was banned. Today, many of these materials are still in situ and represent a source of risk for construction workers. The objective of the study was to analyse the cases of mesothelioma arising among construction workers registered in the Apulia regional register of mesothelioma. RESULTS: For the period 1993-2018, there were 178 male cases, and 10.2% of the cases were present in the regional register. The average age at diagnosis was 64.7 years. The site was pleural in 96.06% of cases, with a diagnosis of certainty in 86.5% of the total cases and 61.8% of cases with epithelial histology. The average latency is 43.9 years. In 75.2% of cases, the exposure began between 1941 and 1970, with an average duration of 24.3 years. The age at the start of exposure in 68.5% of cases is between 8 and 20 years. The ORs were 2.5 (C.I. 95% 1.01-6.17) for the epithelioid histotype and the high duration of exposure. The data underline the need for prevention and information on all activities involving construction workers in which asbestos-containing materials are still used.

Health impact of exposure to asbestos in polluted area of Southern Italy.

The three main sources of asbestos pollution in the city of Bari, Puglia, the former Fibronit asbestos factory, the Torre Quetta beach, the former Rossani barracks and the history of their reclamation are described. The results of cohort studies on factory workers and case-control studies on asbestos exposure to the resident population and the onset of mesothelioma are also reported. Finally, the data of the regional register of mesothelioma related to residents in the city of Bari and four new cases with environmental exposure due to the former Rossani barracks are presented.

Three-trocar laparoscopic cholecystectomy under spinal anesthesia in a patient with asthma.

INTRODUCTION: Laparoscopy is perceived as the state-of-the-art technique for a wide variety of operations but is contraindicated by comorbidities such as respiratory diseases. We present the case of a patient affected by asthma who underwent a successful three-trocar low-pressure pneumoperitoneum under spinal anesthesia. CASE REPORT: A 58 year-old male with symptomatic gallstones had partly-controlled asthma and respiratory allergies. Potential bronchospasm was avoided by a less invasive laparoscopic technique. Under spinal anesthesia open pneumoperitoneum was achieved at the umbilicus. Two more trocars were inserted. A cholecystectomy was performed in 90 minutes keeping the patient in a supine position and the pneumopneumoperitoneum at 8 mmHg. The post-operative course was uneventful. Discharge to home occurred on day two. DISCUSSION: Laparoscopy is contraindicated in the presence of hemodynamic instability and inability of the patient to tolerate laparoscopic surgery. Asthma is caused by bronchoconstriction from a myriad possible stimuli requiring a specific anesthetic plan. Spinal anesthesia under low pressure pneumoperitoneum is a safe alternative to general anesthesia in high risk candidates. In experienced hand, a three-trocar cholecystectomy is safe and feasible. CONCLUSION: Our patient represented a challenging case due to a partly-controlled asthma. Bronchospasm under general anesthesia was prevented by spinal anesthesia to keep a spontaneous physiologic respiration, irrigation of the right subdiaphragmatic surface with lidocaine to control right shoulder pain, safe dissection by three trocars, a pneumoperitoneum at 8 mmHg, the supine position to prevent significant physiologic changes and minimize diaphragmatic irritation.

Treatment plan comparison in acute and chronic respiratory tract diseases: an observational study of doxophylline vs. theophylline.

BACKGROUND: The main objective of this article is to estimate the global cost related to the use of the two drugs (associated drugs, specialist visits, hospital admissions, plasma drug monitoring). METHODS: The drug prescriptions were extracted from the Information System of the Pharmaceutical Prescriptions of the Marche Region for each ATC code in the years 2008-2012 and the number of patients per year and other outcomes measure were obtained. RESULTS: 13,574 patients were treated with theophylline and 19,426 patients with doxophylline. The number of patients treated was approximately 5,000 per year. Co-prescription with other drugs, use of corticosteroids, mean number of visits and hospital admissions (per 100 patients) were lower for doxophylline vs theophylline (1.55vs5.50, 0.3vs0.7, 2.05vs3.73 and 1.57vs3.3 respectively). The annual mean cost per patient was €187.4 for those treated with doxophylline and €513.5 for theophylline. CONCLUSIONS: In our study, doxophylline resulted to be associated with a reduction of the overall cost.

Pharmacological study of the one spike spherical neuron phenotype in Gymnotus omarorum.

The intrinsic properties of spherical neurons play a fundamental role in the sensory processing of self-generated signals along a fast electrosensory pathway in electric fish. Previous results indicate that the spherical neuron's intrinsic properties depend mainly on the presence of two resonant currents that tend to clamp the voltage near the resting potential. Here we show that these are: a low-threshold potassium current blocked by 4-aminopyridine and a mixed cationic current blocked by cesium chloride. We also show that the low-threshold potassium current also causes the long refractory period, explaining the necessary properties that implement the dynamic filtering of the self-generated signals previously described. Comparative data from other fish and from the auditory system indicate that other single spiking onset neurons might differ in the channel repertoire observed in the spherical neurons of Gymnotus omarorum.

Proximate and ultimate causes of signal diversity in the electric fish Gymnotus.

A complete understanding of animal signal evolution necessitates analyses of both the proximate (e.g. anatomical and physiological) mechanisms of signal generation and reception, and the ultimate (i.e. evolutionary) mechanisms underlying adaptation and diversification. Here we summarize the results of a synthetic study of electric diversity in the species-rich neotropical electric fish genus Gymnotus. Our study integrates two research directions. The first examines the proximate causes of diversity in the electric organ discharge (EOD) - which is the carrier of both the communication and electrolocation signal of electric fishes - via descriptions of the intrinsic properties of electrocytes, electrocyte innervation, electric organ anatomy and the neural coordination of the discharge (among other parameters). The second seeks to understand the ultimate causes of signal diversity - via a continent-wide survey of species diversity, species-level phylogenetic reconstructions and field-recorded head-to-tail EOD (ht-EOD) waveforms (a common procedure for characterizing the communication component of electric fish EODs). At the proximate level, a comparative morpho-functional survey of electric organ anatomy and the electromotive force pattern of the EOD for 11 species (representing most major clades) revealed four distinct groups of species, each corresponding to a discrete area of the phylogeny of the genus and to a distinct type of ht-EOD waveform. At the ultimate level, our analyses (which emphasize the ht-EOD) allowed us to conclude that selective forces from the abiotic environment have had minimal impact on the communication component of the EOD. In contrast, selective forces of a biotic nature - imposed by electroreceptive predators, reproductive interference from heterospecific congeners, and sexual selection - may be important sources of diversifying selection on Gymnotus signals.

Fatal hypersensitivity reaction to an oral spray of flurbiprofen: a case report.

WHAT IS KNOWN AND OBJECTIVE: Safety of the anti-inflammatory drug flurbiprofen is comparable with that of other non-steroidal anti-inflammatory drugs of the propionic acid class, which are commonly associated with gastrointestinal and renal side effects. Here we report a case of a fatal hypersensitivity reaction to an oral spray of flurbiprofen taken for sore throat. CASE SUMMARY: A 29-year-old man came to the emergency care unit reporting sore throat with an intense burning sensation associated with fever. Pharyngotonsillitis was diagnosed, and local treatment with oral flurbiprofen spray was prescribed. Immediately after using the spray, the patient experienced a severe reaction characterized by serious dyspnoea, followed by death. The cause of death was heart failure with acute asphyxia from oedema of the glottis. The cause of death was concluded to be hypersensitivity to flurbiprofen spray. WHAT IS NEW AND CONCLUSION: Oral propionic acid derivatives have been associated with a relatively high frequency of allergic reactions. However, allergy to flurbiprofen has rarely been documented. Scientific literature reports two relevant cases of hypersensitivity reaction to flurbiprofen: in one case, a patient presented with a maculopapular rash 48 h after having taken oral flurbiprofen followed by angio-oedema and hypotension. In another case, a single oral dose of flurbiprofen caused itching and swelling around the eyes, redness and increased lacrimation. We describe, for the first time, a fatal case of hypersensitivity reaction to flurbiprofen oral spray. Hypersensitivity reactions to flurbiprofen are infrequent; however, health professionals should be aware of potential adverse reactions, even during topical administration as oral spray.

Assessing the risk of osteonecrosis of the jaw due to bisphosphonate therapy in the secondary prevention of osteoporotic fractures.

SUMMARY: There is evidence that the use oral bisphosphonates can lead to osteronecrosis of the jaws (ONJ). Although the occurrence of ONJ appears rare among oral bisphosphonates (BPs) users, it is important to know that it exists and can be opportunely minimized. INTRODUCTION: The purpose of this study is to evaluate the association between BPs prescribed for the secondary prevention of osteoporotic fractures and the occurrence of ONJ. METHODS: An Italian record linkage claims database with a target population of around 18 million individuals (6 million over 55 years of age) constituted the data source. We conducted a nested case-control study within a cohort of individuals aged 55+ years old, who were discharged from hospitals with a primary diagnosis of incident osteoporotic fracture. The date related to the discharge diagnosis of ONJ was the index date. Conditional logistic regression for matched data was fitted to estimate the odds ratio (OR) along with 95 % confidence intervals (95 % CI) for the likely association between use of BPs and the risk of ONJ. RESULTS: Any one of the 61 ascertained cases of ONJ (incidence rate, 36.6 per 100,000 person-years) was matched to 20 controls for a total of 1120 controls. When the exposure to BPs was modeled according to recency (i.e., exposure time window prior to the index date) of use, the adjusted OR (95 % CI) for current users was 2.8 (1.3-5.9) against never users. The cumulative use of BPs has shown to increase the incidence of ONJ among patients with primary osteoporotic fractures, although not statistically significant risk has been observed. CONCLUSIONS: Although the risk of BP-related ONJ appears low in non-oncological indications, it is important to be aware that it exists and to know how it may be predicted and possibly minimized.

Electric organ discharge diversity in the genus Gymnotus: anatomo-functional groups and electrogenic mechanisms.

Previous studies describe six factors accounting for interspecific diversity of electric organ discharge (EOD) waveforms in Gymnotus. At the cellular level, three factors determine the locally generated waveforms: (1) electrocyte geometry and channel repertoire; (2) the localization of synaptic contacts on electrocyte surfaces; and (3) electric activity of electromotor axons preceding the discharge of electrocytes. At the organismic level, three factors determine the integration of the EOD as a behavioral unit: (4) the distribution of different types of electrocytes and specialized passive tissue forming the electric organ (EO); (5) the neural mechanisms of electrocyte discharge coordination; and (6) post-effector mechanisms. Here, we reconfirm the importance of the first five of these factors based on comparative studies of a wider diversity of Gymnotus than previously investigated. Additionally, we report a hitherto unseen aspect of EOD diversity in Gymnotus. The central region of the EO (which has the largest weight on the conspecific-received field) usually exhibits a negative-positive-negative pattern where the delay between the early negative and positive peaks (determined by neural coordination mechanisms) matches the delay between the positive and late negative peaks (determined by electrocyte responsiveness). Because delays between peaks typically determine the peak power frequency, this matching implies a co-evolution of neural and myogenic coordination mechanisms in determining the spectral specificity of the intraspecific communication channel. Finally, we define four functional species groups based on EO/EOD structure. The first three exhibit a heterogeneous EO in which doubly innervated electrocytes are responsible for a main triphasic complex. Group I species exhibit a characteristic cephalic extension of the EO. Group II species exhibit an early positive component of putative neural origin, and strong EO auto-excitability. Group III species exhibit an early, slow, negative wave of abdominal origin, and variation in EO auto-excitability. Representatives of Group IV generate a unique waveform comprising a main positive peak followed by a small, load-dependent negative component.

Serotonin involvement in Rhodiola rosea attenuation of nicotine withdrawal signs in rats.

Rhodiola rosea has been used for centuries in the traditional medicine to stimulate nervous system, to enhance physical and mental performance and to treat fatigue. It is known that administration of Rhodiola rosea extract elicits antidepressant activity, but the mechanism of action still remains unclear. Evidence from animal models and human studies show that nicotine reduces symptoms of depression and that nicotine cessation induces depressive-like symptoms. We investigated the effects of Rhodiola rosea on nicotine withdrawal signs. Nicotine dependence was induced by subcutaneous nicotine injection (2 mg/kg, four times daily) for 14 days. Another group of animals treated with nicotine (for 14 days) and successively with Rhodiola rosea extract was co-administered with selective 5-HT receptorial antagonist WAY 100635 (1 mg/kg). After nicotine withdrawal animals were evaluated for behavioural parameters (locomotor activity, abstinence signs, marble burying test), diencephalic serotonin metabolism and serotonin receptor-1A expression. Results show a significant increase of 5-HT content in N treated with R. rosea, with a significant increase of serotonin receptor 1A, suggesting an involvement of serotonin in beneficial effects of R. rosea on suffering produced by nicotine withdrawal.

Effects of polydeoxyribonucleotide on the histological damage and the altered spermatogenesis induced by testicular ischaemia and reperfusion in rats.

The effects of polydeoxyribonucleotide (PDRN), an agonist of the A2A adenosine receptors which when activated positively influences sperm activity, were tested in an experimental testicular ischaemia/reperfusion injury model. Anaesthetized male Sprague-Dawley rats were subjected to testicular torsion-induced ischaemia, followed by reperfusion (TI/R). Immediately after detorsion, randomized animals, including SHAM, received intraperitoneal injections of: (i) vehicle (1 mL/kg 0.9% NaCl solution); (ii) PDRN (8 mg/kg); (iii) DMPX (3,7-dimethyl-1-propargilxanthine, 0.1 mg/kg); or (iv) PDRN (8 mg/kg) + DMPX (0.1 mg/kg). Animals were euthanized at 1, 7 and 30 days following reperfusion. Vascular endothelial growth factor (VEGF) expression is normally associated with adenosine A2A receptor stimulation. After treatment, VEGF mRNA/protein expression quantified by qPCR and Western blot, vascular endothelial growth factor receptor-1 (VEGFR1) and endothelial nitric oxide synthase (eNOS) mRNA measured by qPCR, VEGF and VEGFR1 assessed using immunohistochemical methods, histological staining and spermatogenic activity were all analysed. Testis ischaemia-reperfusion (TI/R) injury caused increases in VEGF mRNA and protein, VEGFR1 and eNOS mRNA, histological damage and reduced spermatogenic activity. Immunostaining showed a lower expression of VEGF in germinal epithelial cells and a strong expression of VEGFR1 in Leydig cells after TI/R. PDRN administration increased significantly VEGF message/protein, VEGFR1 and eNOS message, decreased histological damage and ameliorated spermatogenic activity. PDRN might be useful in the management of testicular torsion.

Cardiovascular and gastrointestinal safety of NSAIDs: a systematic review of meta-analyses of randomized clinical trials.

As part of the Safety of Non-Steroidal Anti-Inflammatory Drugs (SOS) Project, we reviewed the incidence of cardiovascular (CV) and gastrointestinal (GI) events associated with the use of this category of drugs. We collected data from published meta-analyses (MAs) of clinical trials of nonsteroidal anti-inflammatory drugs (NSAIDs). The Medline, Cochrane, ISI, and SCOPUS databases were systematically searched for MAs of NSAID clinical trials that could potentially contain data on adverse incidents such as myocardial infarction (MI), cerebrovascular events (CeVs), stroke, thromboembolic events (ThEs), heart failure (HF), gastrointestinal bleeding (GIB), and perforation, ulcer, and bleeding (PUB). From 1,733 identified references, 29 MAs were selected for the review. This allowed 109 estimations of incidence rates of CV adverse events and 26 estimations of incidence rates for GI adverse events. No data were found on hemorrhagic stroke or LGIB. Coxibs were studied in more MAs than traditional NSAIDs were (21 MAs for coxibs vs. 7 for traditional NSAIDs; one meta-analysis studied both). Many NSAIDs were not considered in any of the MAs. Our systematic review of MAs included information on the incidence of CV and GI events and identified important knowledge gaps regarding, in particular, the CV safety of traditional NSAIDs.

Pathogenesis of hypertrophic cardiomyopathy. Impact of growth factors on left ventricular anatomy.

AIM: The aim of this study was to evaluate the effect of insulin-like growth factor 1 (IGF1) and transforming growth factor beta-1 (TGFbeta-1) on collagen turnover, left ventricular (LV) hypertrophy and on passive diastolic function of the LV in hypertrophic cardiomyopathy (HCM). METHODS: This study group comprised 34 patients with non-dilated HCM. Procollagen I amino-terminal propeptide (PINP) and collagen I carboxy-terminal telopeptide (ICTP) were measured by radioimmunoassay. Matrix metalloproteinase 9 (MMP 9), IGF1 and TGFalfa-1 were determined by enzyme-linked immunosorbent assay. The difference in duration between transmitral forward (A) and pulmonary venous retrograde (Ar) waves, was considered as an estimate of passive diastolic function; the ratio between the peak flow velocity at rapid filling at the mitral level (E) and E' measured by tissue Doppler was considered an estimate of active diastolic function. LV mass was measured and normalized to body surface area (LVMi) by cardiac magnetic resonance imaging. RESULTS: LVMi correlates to E/E' (r=0.597, P=0.019 ) and is inversely related to A-Ar (r=0.453, P=0.015). TGFbeta-1 is directly related to active MMP 9 (r=0.439, P=0.012 ). IGF1 is directly related to PICP-ICTP (r=0.347, P=0.501), that expresses the balance between collagen I synthesis and its degradation. CONCLUSION: The study demonstrated that in HCM, LVMi influences active and passive diastolic dysfunction and that IGF1 stimulates collagen synthesis and TGFbeta-1 is related to LV hypertrophy.

Evaluation of the left ventricular anatomy in hypertrophic cardiomyopathy: comparison between echocardiography and cardiac magnetic resonance imaging.

AIM: The aim of this study was to assess the relationship between echocardiographic indexes of left ventricular (LV) hypertrophy with LV mass (LVM) obtained at cardiac magnetic resonance (CMR) in a population of patients with hypertrophic cardiomiopathy (HCM). METHODS: Thirty-nine patients with HCM underwent echocardiography and CMR. By echocardiography maximal wall thickness (MWT), Spirito' and Maron's hypertrophy index and the Wigle's score were obtained. Absolute LVM was measured through CMR and indexed to body surface area (LVMi). Data were analysed using linear regression analysis. RESULTS: In 31% of patients there was an incomplete echocardiographic LV anatomic characterization. However, there was a good correlation between MWT measured at echocardiography and at CMR (P<0.001; r=0.755). Overall echocardiographic indexes of LV hypertrophy correlate with either LVM and LVMi: MWT (P=0.008, r=0.420 and P=0.003, r=0.467, respectively); Spirito' and Maron's hypertrophy index (P=0.003, r=0.551 and P=0.001, r=0.606, respectively) and Wigle's score (P=0.004, r=0.522 and P=0.004, r=0.522, respectively). CONCLUSION: In our HCM population, although a complete anatomic LV anatomic characterization was not obtained by echocardiography in all patients, echocardiographic hypertrophic indexes showed a good correlation with LVM obtained by CMR.

Lipid-lowering drug use in Italian primary care: effects of reimbursement criteria revision.

OBJECTIVE: To assess whether the prescribing pattern of lipid-lowering drugs (LLD) changed after reimbursement criteria revision in a general practice in southern Italy. METHODS: From the Caserta-1 Local Health Service database, 93 general practitioners (GPs) who had consistently sent data about their patients during the years 2003-2005 were recruited. Prevalence of use and incidence of new treatments were calculated for each year, stratified by three drug cohorts: statins, omega-3 fatty acids, and fibrates. Subanalyses by gender, age, and indication of use were performed. RESULTS: Overall, 1-year prevalence of LLD use increased from 2003 to 2004. After reimbursement criteria revision (November 2004), a slight decrease was observed for statins, from 41.1 (95% CI: 39.9-42.2) per 1,000 inhabitants in 2004 to 40.3 (39.2-41.5) in 2005, while omega-3 utilization fell markedly: 14.6 (13.9-15.3) vs. 5.4 (5.0-5.8). The use of both statins and omega-3 fatty acids was reduced particularly for primary prevention. On the other hand, utilization of statins increased in diabetic patients and as secondary prevention from 2004 to 2005. Concerning individual molecules, 1-year prevalence of use of any statin declined from 2004 to 2005, except for rosuvastatin. CONCLUSIONS: Revision of reimbursement criteria led to significant changes in the trend in LLD use in general practice in southern Italy: (1) statin utilization was slightly reduced in 2005, although it increased in certain categories, such as diabetic patients, and (2) omega-3 fatty acid use was strongly reduced even though a higher use in postinfarction cases was reported.
