Automatic and controlled attentional orienting toward emotional faces in patients with Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative motor disorder that can associate with deficits in cognitive and emotional processing. In particular, PD has been reported to be mainly associated with defects in executive control and orienting attentional systems. The deficit in emotional processing mainly emerged in facial expression recognition. It is possible that the defects in emotional processing in PD may be secondary to other cognitive impairments, such as attentional deficits. This study was designed to systematically investigate the different weight of automatic and controlled attentional orienting mechanisms implied in emotional selective attention in PD. To address our purpose, we assessed drug-naïve PD patients and age-matched healthy controls with two dot-probe tasks that differed for stimuli duration. Automatic and controlled attentions were evaluated with stimuli lasting 100 ms and 500 ms, respectively. Furthermore, we introduced an emotion recognition task to investigate the performance in explicit emotion classification. The stimuli used in both the tasks dot-probe and emotion recognition were expressive faces displaying neutral, disgusted, fearful, and happy expressions.Our results showed that in PD patients, compared with healthy controls, there was 1) an alteration of automatic and controlled attentional orienting toward emotional faces in both the dot-probe tasks (with short and long durations), and 2) no difference in the emotion recognition task. These findings suggest that, from the early stages of the disease, PD can yield specific deficits in implicit emotion processing task (i.e., dot-probe task) despite a normal performance in explicit tasks that demand overt emotion recognition.

The quality of parenting in reproductive donation families: A meta-analysis and systematic review.

This review examined whether the absence of a genetic link with one or both parents in families using reproductive donation induced a different quality of parenting from that found in families with spontaneous conception or autologous assisted reproductive technology (AUT-ART), where the genetic mother carries the pregnancy and both parents have a genetic link with their children. MEDLINE, PsycINFO and PubMed were searched for English-language studies published from January 1993 to October 2021. A total of 45 studies were included in the systematic review, and 11 in the meta-analysis. The meta-analysis showed that in reproductive donation families, where there was no genetic link between parents and children, there were higher positive parental values (P = 0.007) and lower negative parental values (P = 0.007) than for parents and children in families that had spontaneously conceived. No statistically significant differences emerged when the reproductive donation families were compared with the AUT-ART families. The study showed that the quality of parenting was not conditioned by the presence or absence of a genetic link; instead, it was influenced by the processes underlying family building, such as the desire to have a child, the involvement of both parents in the childcare and the quality of disclosure.

False memories formation is increased in individuals with insomnia.

Previous studies suggest that sleep can influence false memories formation. Specifically, acute sleep loss has been shown to promote false memories production by impairing memory retrieval at subsequent testing. Surprisingly, the relationship between sleep and false memories has only been investigated in healthy subjects but not in individuals with insomnia, whose sleep is objectively impaired compared to healthy subjects. Indeed, this population shows several cognitive impairments involving prefrontal functioning that could affect source monitoring processes and contribute to false memories generation. Moreover, it has been previously reported that subjects with insomnia differentially process sleep-related versus neutral stimuli. Therefore, the aim of the present study was to compare false memories production between individuals with insomnia symptoms and good sleepers, and to evaluate the possible influence of stimulus category (neutral versus sleep-related) in the two groups. The results show that false memories are globally increased in participants reporting insomnia symptoms compared to good sleepers. A reduction in source monitoring ability was also observed in the former group, suggesting that an impairment of this executive function could be especially involved in false memories formation. Moreover, our data seem to confirm that false memories production in individuals with insomnia symptoms appears significantly modulated by stimulus category.

Characterization of a novel CDC73 gene mutation in a hyperparathyrodism-jaw tumor patient affected by parathyroid carcinoma in the absence of somatic loss of heterozygosity.

Hyperparathyrodism-jaw tumor (HPT-JT) syndrome is an autosomal dominant disorder. Loss of function of the cell division cycle protein 73 homolog (CDC73) gene is responsible for the syndrome. This gene encodes an ubiquitously expressed 531 amino acid protein, parafibromin, that acts as a tumor suppressor. Loss of heterozygosity (LOH) of the CDC73 locus in many HPT-JT associated parathyroid tumors from patients with germline mutation is in accordance with Knudson's "two-hit" model for hereditary cancer. A 41-year-old man with mandible ossifying fibroma suffered from severe hypercalcemia due to parathyroid carcinoma (PC). Genetic analysis was performed to evaluate germinal and somatic CDC73 gene mutation as well as real-time qRT-PCR to quantify CDC73 mRNA, miR-155 and miR-664 expression levels. Immunohistochemistry and Western blotting (WB) assay were carried out to evaluate parafibromin protein expression. A novel heterozygous nonsense mutation, c.191-192 delT, was identified in the CDC73 gene. No CDC73 LOH was found in PC tissue, nor any differences in expression levels for CDC73 gene, miR-155 and miR-664 between PC and parathyroid adenoma control tissues. On the contrary, both immunohistochemistry and WB assay showed an approximate 90% reduction of parafibromin protein expression in PC. In conclusion, this study describes a novel germinal mutation, c.191-192 delT, in the CDC73 gene. Despite normal CDC73 gene expression, we found a significant decrease in parafibromin. We hypothesize that a gene silencing mechanism, possibly induced by microRNA, could play a role in determining somatic post-transcriptional inactivation of the wild type CDC73 allele.

Prevalence of Chronic Hypoparathyroidism in a Mediterranean Region as Estimated by the Analysis of Anonymous Healthcare Database.

Epidemiological data on prevalence and incidence of chronic hypoparathyroidism are still scarce. This study aimed to establish prevalence of chronic hypoparathyroidism and incidence of surgical hypoparathyroidism using the analysis of electronic anonymous public health care database. Data referred to a 5-year period (2009-2013, Region of Tuscany, Italy, as a sample representative of the whole Mediterranean/European population, estimated mean population: 3,750,000 inhabitants) were retrieved by the analysis of pharmaceutical distribution dataset, containing data related to drugs reimbursed by public health system, hospital discharge and procedures codes, and ICD9 exemption codes for chronic diseases. The application of a specific algorithm was applied to indirectly identify people with chronic hypoparathyroidism as assuming chronic therapy with active vitamin D metabolites (AVDM). The number of people taking AVDM for a period equal to or longer than 6 months till the end of the study period, with ICD9 exemption code for hypoparathyroidism, and with a disease-related discharge code were identified. Within this restricted group, patients with chronic kidney disease and osteoporosis were excluded. The indirect estimate of chronic hypoparathyroidism in a European Mediterranean subpopulation by means of the analysis of chronic therapy with AVDM was 27/100,000 inhabitants (female:male ratio = 2.2:1), with a mean age of 63.5 ± 16.7 years. The risk of developing hypoparathyroidism after neck surgery was 1.5%. While the epidemiological approaches based on disease code and hospital discharge code greatly underestimates the prevalence of hypoparathyroidism, the indirect estimate of this disease through the analysis of prescriptions of AVDM in a European region is in line with the results of studies performed in other regions of the world.

Natural History of MEN1 GEP-NET: Single-Center Experience After a Long Follow-Up.

BACKGROUND: The multiple endocrine neoplasia type 1 syndrome (MEN1) natural history is poorly evaluated, and few single-institution experiences about hereditary gastroenteropancreatic neuroendocrine tumors (GEP-NET) are reported. Our purpose is to analyze the role of GEP-NET in MEN1-related death, as well as the behavior of these lesions during follow-up. METHODS: The study population consists of 77 patients diagnosed with MEN1 GEP-NET, regularly followed up since 1990. Extensive clinical data were prospectively recorded. Statistical analysis was performed both on the whole population of 77 patients and on two subgroups including patients who, during the long lasting study period, underwent GEP-NET surgery (50 pts) and who did not (27 pts), respectively. RESULTS: Twenty-five males (32.5%) and 52 females (67.5%) were enrolled. Sixty-four patients had MEN1 family history (83.1%), and genetic mutation was detected in 67 cases (87%). The mean age at GEP-NET diagnosis was 41.4 years (SD = 13.6); 16 patients (20.8%) had GEP-NET diagnosed before age 30 and 12 cases (15.6%) before 1996. The mean interval time between MEN1 diagnosis and GEP-NET detection was 5.7 years (range -11/37; SD = 8.1 years). Overall, the mean follow-up time from MEN1 diagnosis was 15.8 years (SD = 9.7 years) and from GEP-NET diagnosis was 9.6 years (SD = 6.9 years). Gastrinoma was the most frequent functioning GEP-NET and pancreatoduodenectomy the most adopted surgery. GEP-NET progression affected 12 patients within the non-surgical group, while 18 subjects developed progression after surgery. CONCLUSIONS: Our single-center data provide information on epidemiologic, clinical and pathological features of GEP-NET in MEN1 making possible to clarify their natural history.

Results of surgical treatment for jejunal Crohn's disease: choice between resection, strictureplasty, and combined treatment.

PURPOSE: The jejunum is a relatively uncommon localization of Crohn's disease (CD) compared to the terminal ileum or the large bowel. The type of surgery and the short and long-term results after surgery have not been extensively investigated. A review of patients who underwent surgery for jejunal CD in our center was examined. METHODS: Between 1986 and 2011, 110 patients underwent surgery for jejunal CD. Thirty patients (27.3 %) were surgically treated with resection, 29 patients (26.4 %) with one or more strictureplasties, and 51 patients (46.3 %) with both a resection and one or more strictureplasties. RESULTS: There was no statistical difference in terms of short-term postoperative complications between patients operated with three different options (p = 0.72). Patients were followed up for a period ranging from 2 to 18 years (mean 11 years). During this period, 42 patients had no CD recurrence, 11 patients had medical recurrences only, while 57 patients had surgical recurrences, too. There was no statistical difference in terms of medical and surgical recurrence between the three types of surgical procedures employed (p = 0.24) and between smokers and non-smokers. The recurrent CD was prevalently treated with strictureplasty. CONCLUSIONS: The most frequently employed surgery for the treatment of jejunal CD is a combined type of treatment, i.e., resection of the most affected tract and strictureplasty of the residual strictures. This approach does not imply an increased risk of postoperative complications and recurrence and can reduce the risk of the short bowel syndrome.

Low-dose diclofenac in patients with fragility fractures.

Most osteoporotic patients complain of back pain one year after a fragility vertebral fracture and the frequency of chronic back pain increases with increasing age. The use of the lowest effective dose of an analgesic which is able to control symptoms seems to be a possible solution in order to limit potential side effects in multi-treated elderly patients. Non-steroidal anti-inflammatory drugs (NSAIDs) have a proven efficacy in the treatment of back pain associated with fragility vertebral fractures and diclofenac is available at low-dose subcutaneous injective formulation. This is the rational of ImPAVeDic study, acronym of Improvement of back Pain Associated with fragility Vertebral fractures with low-dose Diclofenac, an observational study that will be performed in a group of 50 elderly (≥ 65 years), male and female osteoporotic patients with symptomatic fragility vertebral fractures. The objective of the study is to evaluate the improvement of back pain in the study population treated with low-dose diclofenac and regularly monitored for 2-6 months. Visual Analogic Scale (VAS) and Numerical Rating Scale (NRS) will be used for pain monitoring. The reduction of the risk of occurrence of drug side effects can favour the optimization of elderly patients' care.

The use of cholecalciferol in patients with hip fracture.

INTRODUCTION: Major osteoporotic fractures are steadily increasing due to population aging. Programs of secondary prevention against refracture are essential to decrease morbidity and mortality and the cost for individuals and the society. Vitamin D supplementation and optimization of calcium intake are of a pivotal importance to start specific osteoporosis treatment and for its safety and efficacy. Cholecalciferol is the most widely employed drug for vitamin D supplementation. PURPOSE: Aim of this study was to assess the trends in the use of vitamin D supplements containing cholecalciferol in the population of hip fracture patients older than 65 years, resident in the region of Tuscany (Italy) in the years 2011-2015 and to describe vitamin D status in a subgroup of this individuals directly referred to a bone clinic for further evaluation after hip osteoporotic fracture. METHODS: Data were retrieved from the electronic anonymous regional administrative database administered by the Region of Tuscany (Italy) in the years 2011-2015 within the T.A.R.Ge.T. project (Trattamento Appropriato delle Rifratture Geriatriche in Toscana, i.e., "Appropriate treatment of geriatric refractures in Tuscany"), a program endorsed by the region itself. Data pertaining to cholecalciferol prescriptions and hospital discharge codes were retrieved and appropriately crossed to get data on the use of cholecalciferol supplements in patients before and after a hip fracture. A retrospective analysis was carried out in a subgroup of subjects (n 254) appropriately referred to the local fracture liaison service after the major osteoporotic fracture and vitamin D status in terms of serum 25(OH) vitamin D levels was assessed. RESULTS: The majority of subjects experiencing a hip fracture (98.2% and 88.3% in 2011 and 2015, respectively) did not receive vitamin D supplements at the time of the fracture event. Although a trend in increase in prescriptions for cholecalciferol supplements could be observed in the years of the study, the percentage of treated individuals remained low even after the fracture, since only 30-35% of subjects receives cholecalciferol supplements at one year after the fracture. Cholecalciferol remained the most prescribed drug in this population, while a substantial decrease of cholecalciferol in association with calcium salts was observed. The use of high doses of cholecalciferol has decreased in this population, while diminished the use of the drops has been accompanied by an increase in prescriptions of single monthly dose supplements. CONCLUSIONS: The correction of vitamin D inadequacy is preliminary to any treatment for osteoporosis and together with calcium may reduce fracture risk by itself. The prescription of vitamin D supplements is low in patients before and after a hip fracture in a Mediterranean region and despite the overall increase in vitamin use and abuse in the general population. Proper educational programs and active fracture liaison services are needed in order to bridge this gap.

Parental disclosure of assisted reproductive technology (ART) conception to their children: a systematic and meta-analytic review.

STUDY QUESTION: Does a genetic link and/or a child's age influence a parent's willingness to talk to a child about how they were conceived? SUMMARY ANSWER: The presence/absence of a biological link and the child's age clearly influences the disclosure process. WHAT IS KNOWN ALREADY: The research published to date has yielded diverse findings on autologous and donor assisted reproductive technology (ART) parents' disclosure of the conception method to their children and on the ages at which the children are informed, if told. STUDY DESIGN, SIZE, DURATION: A systematic review and meta-analysis were carried out. A search of MEDLINE and PUBMED was run for English-language studies published from January 1996 through January 2015. A total of 26 studies were included in the systematic review, 19 of which were included in the meta-analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 2814 parent responses were included in the systematic review. Two authors independently assessed the studies for review inclusion. Selection criteria were: peer-reviewed studies, quantitative studies only, research conducted after the birth of ART-conceived children, number of parent responses on disclosure status reported in terms of Told, Plan to tell, Uncertain, Plan to not tell. Thirty-two (32) study-level effect size statistics were included in the meta-analysis. Three authors independently assessed the risk of bias. MAIN RESULTS AND THE ROLE OF CHANCE: Among parents who responded, 23% of the total number of parent responses indicated that they had already Told; 44% were Planning to tell; 13% were Uncertain and 20% were Planning to not tell their children about their ART conception. Meta-analysis gave no statistically significant differences between autologous and donor ART in the <10 years age group, when comparing Told versus Planning to tell/Uncertain/Planning to not tell. In both cases, the probability of disclosure was <50% (P < 0.05). Conversely, in the older age group (≥10 years old), a statistically significant difference was observed for autologous ART (Cohen's h = 0.86): Planning to tell showed a higher probability in the 10 years age group for the autologous ART subsample, than in the donor ART subsample (Cohen's h = 0.89). LIMITATIONS, REASONS FOR CAUTION: All parents participated voluntarily in the studies and may have influenced the data in the direction of disclosure thereby. The reviewed studies, moreover, differed in terms of methodology, type of sample and data categorization method. The number of studies analyzing disclosure for children ≥10 years was quite limited; and lastly, most of the data examined were not collected longitudinally. IMPLICATIONS OF THE FINDINGS: The high number of non-disclosing parents treated by donor ART points to an underestimation of the medical risks for the offspring (the presence of genetic illnesses, inadvertent consanguinity) and suggests that these children's rights may not be given due consideration. The decision to disclose may become more difficult over time, and ART parents need greater psychological support throughout the process. STUDY FUNDING/COMPETING INTERESTS: The study was funded by the University of Trieste.

Systematic and Meta-Analytic Review: Triggering Agents of Parental Perception of Child's Vulnerability in Instances of Preterm Birth.

OBJECTIVE: Parental perception of a child vulnerability (PPCV) to illness, not justified by medically noticeable symptoms, is a situation well known to medical and paramedical staff. It is still disputed whether PPCV is triggered by the child's health problems or by parental emotional status. This review is aimed to clarify the etiology of PPCV in instances of preterm birth. METHOD: PRISMA guidelines were followed. MEDLINE and Scopus indexes were searched. Of the 70 articles yielded by the search, 14 met the inclusion criteria for the systematic review, of which 10 could be included in the meta-analysis. RESULTS: Children's physiological factors and parents' psychological factors were both found to significantly influence PPCV, in different ways, at different ages of the child. CONCLUSION: PPCV etiology appears to mostly depend on parents' psychological factors. A better understanding of PPCV etiology could help protect children from distorted parental interaction and reduce parental demands for unnecessary medical care.

The T.A.R.Ge.T. project: a regional program to reduce hip fracture in elderly patients. Main results of retrospective phase.

The Tuscany Region was the first Italian Region to initiate a program for the prevention of hip fractures in over 65 year old. The T.A.R.Ge.T. project "Appropriate treatment of geriatric re-fractures in Tuscany" (Trattamento Appropriato delle Rifratture Geriatriche in Toscana), which is still on-going, includes a preliminary phase (2009-2010) for baseline analysis and education of the participating centers and a 4-year-prospective phase (2011-2014). The monitoring system is performed horizontally analyzing 5 different flows: SDO (Performance Hospitalization), SPF (Pharmaceutical Distribution Dataset), FED (Direct Distribution Dataset), SAA (Registry of Patients), SPA (Specialized Outpatient) flows. In this review will be shown some of the most important results of analyzes of the retrospective phase. Between 2006 and 2011 only 26% of hip fractured patients has being treated with anti-osteoporotic drugs. The percentage of treatment increases 10% after the second fracture. Until 2011 there wasn't in Tuscany a prevention program of bone fragility; patients were treated with specific treatment only in severe cases: this phenomenon implies that mortality and re-fracture are higher on treated patients than in patients who did not have any kind of treatment. The treated patients are the most severe and therefore they have a higher risk of death and re-fracture.

Dual-Process Theory of Thought and Inhibitory Control: An ALE Meta-Analysis.

The dual-process theory of thought rests on the co-existence of two different thinking modalities: a quick, automatic, and associative process opposed to a slow, thoughtful, and deliberative process. The increasing interest in determining the neural foundation of the dual-process distinction has yielded mixed results, also given the difficulty of applying the fMRI standard approach to tasks usually employed in the cognitive literature. We report an activation likelihood estimation (ALE) meta-analysis to investigate the neural foundation of the dual-process theory of thought. Eligible studies allowed for the identification of cerebral areas associated with dual-process theory-based tasks without differentiating between fast and slow thinking. The ALE algorithm converged on the medial frontal cortex, superior frontal cortex, anterior cingulate cortex, insula, and left inferior frontal gyrus. These structures partially overlap with the cerebral areas recurrently reported in the literature about the neural basis of the dual-process distinction, where the PARCS theory-based interpretation emphasizes the role of the right inferior gyrus. The results confirm the potential (but still almost unexplored) common ground between the dual-process literature and the cognitive control literature.

Interplay among Anxiety, Digital Environmental Exposure, and Cognitive Control: Implications of Natural Settings.

Inhibitory control performance may differ greatly as a function of individual differences such as anxiety. Nonetheless, how cognitive control proficiency might be influenced by exposure to various environments and how anxiety traits might impact these effects remain unexplored. A cohort of thirty healthy volunteers participated in the study. Participants performed a Go/No-Go task before exposure to a 'forest' and 'urban' virtual environment, in a counterbalanced design, before repeating the GNG task. The State-Trait Anxiety Inventory (STAI) was finally filled-in. Our findings unveiled an initial negative correlation between anxiety trait levels and GNG task performance, consistent with the established literature attributing difficulties in inhibitory functionality to anxiety. Additionally, different environmental exposures reported opposite trends. Exposure to the 'forest' environment distinctly improved the GNG performance in relation to anxiety traits, while the 'urban' setting demonstrated adverse effects on task performance. These results underscore the intricate relationship among cognitive control, environmental exposure, and trait anxiety. In particular, our findings highlight the potential of natural settings, such as forests, to mitigate the impact of anxiety on inhibition. This might have implications for interventions aimed at improving cognitive control.

Intuitive thinking predicts false memory formation due to a decrease in inhibitory efficiency.

False memory formation is usually studied using the Deese-Roediger-McDermott paradigm (DRM), in which individuals incorrectly remember words that were not originally presented. In this paper, we systematically investigated how two modes of thinking (analytical vs. intuitive) can influence the tendency to create false memories. The increased propensity of intuitive thinkers to generate more false memories can be explained by one or both of the following hypotheses: a decrease in the inhibition of the lure words that come to mind, or an increased reliance on the familiarity heuristic to determine if the word has been previously studied. In two studies, we conducted tests of both recognition and recall using the DRM paradigm. Our observations indicate that a decrease in inhibitory efficiency plays a larger role in false memory formation compared to the use of the familiarity heuristic.

Effects of Plant-Emitted Monoterpenes on Anxiety Symptoms: A Propensity-Matched Observational Cohort Study.

Immersive experiences in green areas, particularly in forests, have long been known to produce beneficial effects for human health. However, the exact determinants and mechanisms leading to healthy outcomes remain to be elucidated. The purpose of this observational cohort study was to investigate whether inhaling plant-emitted biogenic volatile compounds, namely monoterpenes (MTs), can produce specific effects on anxiety symptoms. Data from 505 subjects participating in 39 structured forest therapy sessions at different Italian sites were collected. The air concentration of monoterpenes was measured at each site. STAI state questionnaires were administered before and after the sessions as a measure of anxiety. A propensity score matching analysis was then performed, considering an above-average exposure to inhalable air MTs as the treatment. The estimated effect was -1.28 STAI-S points (95% C.I. -2.51 to -0.06, p = 0.04), indicating that the average effect of exposure to high MT air concentrations during forest therapy sessions was to decrease anxiety symptoms.

Cognitive style predicts how people explain mental magic tricks.

Magic tricks are deceiving, yet we can readily generate an explanation for a trick that we do not fully understand. In three experiments, we show that the way people explain a mental magic trick depends on their individual cognitive style. Analytical thinkers tend to generate explanations that appeal to rationality, such as using physical props to accomplish an effect. In contrast, intuitive thinkers are more likely to generate irrational explanations that accord with the magician's provided backstory, such as using subliminal cues to guide a spectator's choices. We observe this effect when measuring a participant's cognitive style using the Cognitive Reflection Test, and also when manipulating a participant's cognitive style using a simple narrative prompt.

Regular and random judgements are not two sides of the same coin: Both representativeness and encoding play a role in randomness perception.

The overalternating bias is that people rate sequences with an excess of alternation as more random than prescribed by information theory. There are two main explanations: the representativeness heuristic (Kahneman & Tversky Cognitive Psychology, 3, 430-454, 1972) and the implicit encoding hypothesis (Falk & Konold Psychological Review, 104, 301-318, 1997). These hypotheses are associated with different reaction times predictions. According to the encoding hypothesis, reaction times should increase as the complexity of the sequence increases, whereas the representativeness heuristic predicts fast reaction times only for more complex sequences that appear more random. We asked participants to guess the generating source of pairs of sequences of dichotomous elements in two different conditions: selecting the string generated by a random source or selecting the string generated by a nonrandom source. Results suggest that both the encoding strategy and the representativeness heuristic have a role in randomness perception and that the two criteria may have a different weight when determining the randomness versus the regularity of a string.

The Mediterranean Diet in Osteoporosis Prevention: An Insight in a Peri- and Post-Menopausal Population.

Osteoporosis represent a widespread public health problem. The management and prevention of osteoporosis and related low energy fractures start with a correct lifestyle and proper nutrition. Several different nutrients are essential for bone and mineral metabolism, especially calcium. Nevertheless, a well-balanced nutrition, such as Mediterranean diet (MD), proved to be beneficial for several chronic diseases and also fragility fractures resulted lower in the Mediterranean area. A prospective observational study in a population of two hundred peri- and post-menopausal women (aged 30-80 years) was developed at Careggi hospital, Florence. Both MD adherence and dietary calcium intake were evaluated in occasion of a "first visit" and a "follow-up" visit, through validated questionnaires. From a descriptive point of view, although not statistically significant, in both visits a slight increase in calcium intake was observed for high adherence to MD diet. Moreover, a short nutritional interview (20 min) was applied in our population and demonstrated to be sufficient to significantly improve MD adherence level (mean score at T0 = 6.98 ± 1.74 and T1 = 7.53 ± 1.68), opening promising paths in osteoporosis prevention.

Chronic hypoparathyroidism and treatment with teriparatide.

PURPOSE: Chronic hypoparathyroidism is usually treated with calcium and active vitamin D metabolites or analogs, despite the fact that their chronic use can lead to long-term complications. The use of hormone replacement therapy with PTH peptides [teriparatide and rhPTH (1-84)] has therefore been proposed. The main purpose of this study was to investigate the efficacy of teriparatide dose at 20 µg once or twice daily, in order to maintain normocalcemia reducing standard treatment, in adult patients with chronic hypoparathyroidism not well controlled with conventional treatment. METHODS: The study was a Phase III, open-label, non-comparative, clinical investigation (study period: 3 months), at a tertiary care clinical research center. Thirty patients with chronic hypoparathyroidism were screened, and 12 started teriparatide. After the optimization phase (0-4 weeks), calcium and calcitriol supplements were progressively reduced, while teriparatide 20 µg once daily was administered (5-7 weeks), and then could be titrated up to 20 µg twice daily (7-17 weeks). The main outcome measures included serum and urinary biochemical exams and Rand 36-Item Short Form Health Survey. RESULTS: This study showed that teriparatide 20 µg once daily was insufficient to discontinue calcium and calcitriol supplements to maintain normal serum calcium concentrations. Conversely, for more than half of patients treated with teriparatide 20 µg twice daily, calcium and calcitriol administration was avoidable, but in some cases at the expense of serum calcium and phosphate oscillations. CONCLUSIONS: Since intervention trials evaluating the efficacy and safety of teriparatide in hypoparathyroid patients are not yet available, the routine use of this molecule poses some doubts.
