Factors That Predict 1-Year Incident Hip and Non-Hip Fractures for Home Care Recipients: A Linked-Data Retrospective Cohort Study

ObjectivesThe purpose of our study was to identify factors that predict 1-year incident hip and major osteoporotic non-hip fractures (ie, wrist, spine, pelvis, humerus) for home care recipients while accounting for the competing risk of death.DesignWe conducted a retrospective cohort study with linked population data.Setting and ParticipantsAll home care recipients in Ontario, Canada, receiving services for more than 6 months with an admission assessment between April 1, 2011, and March 31, 2015, were included.MethodsClinical data from the Resident Assessment Instrument Home Care were linked to fracture data from the Discharge Abstract Database and the National Acute Care Reporting System. Competing risk proportional hazard regressions using the Fine and Grey method were performed to model the association between potential risk factors and fracture.ResultsPrevious fall, previous fracture, cognitive impairment, unsteady gait, alcohol use, tobacco use, and Parkinson disease were consistently associated with all fracture types. Cognitive impairment (hazard ratio 2.09; 95% confidence interval 1.86–2.36) and wandering [1.66 (1.06–1.27)] were most predictive of hip fractures and being female [1.86 (1.76–1.98)] and experiencing a previous fracture [1.86 (1.76–1.98)] were most predictive of non-hip fractures. Risk factors unique to non-hip fractures as compared with hip fractures were locomotion ability outdoors and psychotropic medication use.Conclusions and ImplicationsOur results indicate that, in addition to typical fracture risk factors, home care recipients have unique characteristics that increase their risk. Fracture risk assessment tools and subsequent prevention strategies should be modified to accurately identify home care recipients at risk for imminent 1-year fracture.     

Family planning in Italy

In the past 5 years, four knowledge, attitude and practice (KAP) surveys on family planning have been organized by the Unit of Population Survey Methodology of the Istituto Superiore di Sanita' (National Institute of Health). These surveys show that during the past 20 years, use of reliable contraceptives in Italy has increased, particularly in the North, encouraged by the more open attitude toward sexual behavior, following legalization of the provision of information on contraception and abortion upon request, and other social and cultural changes.In 1989 and 1991, 25% of women in Central and Southern Italy were using the pill or an IUD. However, the percentage of women not using contraceptives was still high (26% in 1989, and 19% in 1991) and withdrawal was the most widley used method (31% and 33%). The data show large regional differences.The main reasons for not using contraception, in the 1989 study, were fear of side-effects and ignorance, especially in the youngest and oldest women. Those least likely to use modern contraception were the young, the ill-educated and the nulliparous women.Lack of information seems to be the main problem in Italy. In fact, the 5044 women interviewed showed a medium level of knowledge of contraception, with only 63% who could identify correctly the fecund period in the menstrual cycle. However, their attitude toward the use of modern contraception was positive; 65% of the women interviewed said they would recommend the Pill or an IUD to a friend, and 10% of them would recommend condoms.Induced abortion is still common in Italy (13 reported abortions per 1000 women aged 15–44), although the incidence has steadily decreased since 1982. In the vast majority of cases, abortion was an emergency measure after the failure of contraceptive methods. It has been calculated that from 10% to 50% of induced abortions might be prevented in a short period through appropriate programs of health education and family planning involving the 2474 governmental maternal and child healt clinics in Italy.

Resumen En los 5 últimos años, la Sección de Metodología de Encuestas Demográficas del Istituto Superiore di Sanità realizó cuatro estudios de conocimiento, actitud y práctica (KAP) respecto a la planificación familiar. Estos estudios indican que, en los 20 últimos años, el uso de anticonceptivos fiables en Italia ha aumentado, especialmente en el norte, fomentado por una actitud más abierta en cuanto a la conducta sexual, tras la legalización y otros cambios sociales y culturales.En 1989 y 1991, el 25% de las mujeres de la región central y meridional de Italia utilizaban la pídora o el DIU. Sin embargo, el porcentaje de mujeres que no utilizaban anticonceptivos continuaba siedo alto (26% en 1989 y 19% en 1991) y elcoitus interruptus era el método más utilizado (31% y 33%). Los datos indican grandes differencias regionales.Los motivos principales de la no utilización de anticonceptivos, en el estudio de 1989, eran el temor a los efectos secundarios y la ignorancia, especialmente entre las mujeres de menor y de mayor edad. Las que probablemente menos utilizaran anticonceptivos modernos eran las mujeres jóvenes, las de bajo nivel de educación y las nulíparas.La falta de información parece ser el problema principal en Italia. En realidad, las 5044 mujeres entrevistadas tenían un nivel medio de conocimiento y sólo el 63% pudo identificar correctamente el período de fecundidad del ciclo menstrual. Sin embargo, su actitud respecto al uso de anticonceptivos modernos era positiva; el 65% de las mujeres entrevistadas manifestaron que recomendarían la píldora o el DIU a una amiga y el 10% de ellas recomendarían preservativos.El aborto provocado continúa siendo común en Italia (13 abortos notificados por cada 1000 mujeres de 15–44 años de edad) si bien su incidencia ha disminuido constantemente desde 1982. En la gran mayoría de los casos, el aborto era una medida de emergencia después del fracaso de un método anticonceptivo. Se ha calculado que del 10 al 50% de los abortos provocados podría impedirse en un plazo breve mediante programas apropiados de educación sanitaria y planificación familiar con la participación de las 2474 clínicas maternoinfantiles estatales de Italia.

Resumé Au cours de cinq dernières années, le service chargé de la méthodologie pour les enquêtes sur la population à l'Istituto Superiore di Sanità a organisé quatre enquêtes sur les connaissances, les attitudes et les pratiques en matière de planning familial. Ces enquêtes ont révélé qu'au cours de vingt dernières années en Italie, l'utilisation de contraceptifs fiables s'est répandue, notamment dans le nord du pays, encouragée par une attitude plus ouverte à l'égard du comportement sexuel à la suite de changements législatifs et autres dans le domaine social et culturel.En 1989 et 1991, 25% des femmes en Italie centrale et méridionale utilisaient la pilule ou un DIU. Le pourcentage de femmes ne faisant appel à aucune méthode de contraception était cependant encore élvé (26% en 1989 et 19% en 1991) et le retrait était la méthode la plus fréquemment adoptée (31% et 33%). Les données font apparaître d'importantes différences régionales. D'après l'étude de 1989, les raisons essentielles du non emploi des contraceptifs provenaient de la crainte d'éventuels effects secondaires et de l'ignorance, surtout chez les juenes et les femmes plus âgées. Les femmes les moins susceptibles de faire appel à la contraception moderne étaient les jeunes, les femmes peu éduquées et les nullipares.Le manque d'information semble être le problème principal en Italie. En fait, les 5044 femmes interrogées ont fait preuve de connaissances moyennes sur la contraception, 63% à peine étant capables d'identifier correctement la période de fécondité du cycle menstruel. Leur attitude à l'égard de la contraception moderne était cependant positive; 65% des femmes interrogées ont répondu qu'elles recommanderaient la pilule on un DIU à une amine, et 10% qu'elles recommanderaient le préservatif.Les avortements provoqués sont encore fréquents en Italie (13 avortements signalés pour 1000 femmes de 15 à 44 ans), mais leur incidence a progressivement diminué dequis 1982. Dans la grande majorité des cas, l'avortement est une mesure d'urgence après l'échec des méthodes de contraception. On a calculé que 10 à 50% des avortements provoqués pourraient être évités en peu de temps si l'on prévoyait des programmes appropriés d'éducation sanitaire et de planning familial dans les 2474 cliniques maternelles et infantiles qui existent en Italie.

Pilot study on compulsory vaccination coverage

The disappearance of diphtheria and poliomyelitis is the best evidence of the efficacy of the vaccination strategies adopted in Italy. The active offer of the prophylaxis, reinforced by law, has characterised the operational aspects of the strategy. The active surveillance system is the main tool to take under control the effectiveness of health services responsible for vaccination. This system could be more easily implemented if the health services will be given a specific software aiming to handle and evaluate vaccination registers. The present pilot study, performed in the regions Marche and Sardegna, is an example of active surveillance and it is based on the ARVA software produced by the Istituto Superiore di Sanità. The results show a good level of coverage (> 95%) within the second year of life. Unsatisfactory results were obtained on the timing of vaccinations, as recommended by the vaccination schedule, mostly for the third doses.     

Congenital forms of hypothyroidism: study of risk factors and preventive interventions

Maternal and child health represents one of the most relevant fields of interest in public health and particular attention is given to congenital pathologies. In Italy, the incidence of congenital hypothyroidism (CH) is 1:3200 live birth. CH is diagnosed at birth by neonatal thyroid screening. This allows a precocious onset of substitutive therapy which avoids severe psychomotor deficits in infants with CH. Moreover, the newborn screening program have permitted to identify transient disorders of thyroid function in newborns. These are essentially due to neonatal, maternal and environmental risk factors, especially iodine deficiency. The National Register (NR) of infants with CH was established in 1987. The aim of the NR is to provide disease surveillance and to monitor efficiency and effectiveness of neonatal screening. Furthermore, the NR represents an useful tool for developing epidemiological studies to identify possible environmental and/or familial risk factors of CH.     

Prenatal effects of natural calcium supplement on Wistar rats during organogenesis period of pregnancy

The potential of oral exposure to calcium and magnesium citrate, a natural product obtained from dolomite, to initiate teratogenesis was analyzed in Wistar rats. Animals received calcium and magnesium citrate oral doses of 250, 500 and 1000 mg/kg during the period of gestation from day 6 to 17 post conception. Maternal, embryo and fetal toxicity was evaluated. Calcium and magnesium citrate exposure did not produce maternal toxicity assessed by clinical observations, body weight gain, food intake, hematology, biochemical parameters and necropsy finding. Signs of embryo–fetal toxicity were not observed. Skeletal and visceral malformations were seen occasionally in all drug-treated and control groups. Skeletal and visceral variations were similar in control and drug-treated groups except for incomplete ossification rib. These finding was spontaneous and unrelated to the drug. In conclusion, in this study we found that the oral exposure to rats of up to 1000 mg/kg of calcium and magnesium citrate during organogenesis did not induce significant maternal and embryo–fetal toxicity. The experimentally derived NOAEL for developmental toxicity was 1000 mg/kg.     

Metformin Prevented Dopaminergic Neurotoxicity Induced by 3,4-Methylenedioxymethamphetamine Administration

Metformin, a well-known antidiabetic drug, has recently been proposed to promote neurogenesis and to have a neuroprotective effect on the neurodegenerative processes induced by the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in models of Parkinson’s disease. Interestingly, metformin has antioxidant properties and is involved in regulating the production of cytokines released during the neuroinflammatory process. Several studies have reported that 3,4-methylenedioxymethamphetamine (MDMA), a recreational drug mostly consumed by young adults, produces a persistent loss of dopaminergic neurons in the substantia nigra pars compacta (SNc) and caudate putamen (CPu) of mice. The aim of this study was to investigate the potential neuroprotective effect of metformin against short- and long-term neurotoxicity induced by MDMA and its role on MDMA-induced hyperthermia. Adult mice received metformin (2 × 200 mg/kg, 11-h intervals, administered orally), MDMA (4 × 20 mg/kg, 2-h interval, administered intraperitoneally), or MDMA plus metformin (2 × 200 mg/kg, 1 h before the first MDMA administration and 4 h after the last). On the second and third day, mice were treated with vehicle or metformin (1 × 200 mg/kg) and sacrificed 48 h and 7 days after the last MDMA administration. The neuroprotective effect of metformin on MDMA-induced dopaminergic damage was evaluated by dopamine transporter (DAT) and tyrosine hydroxylase (TH) immunohistochemistry in SNc and CPu. Metformin prevented the MDMA-induced loss of TH-positive neurons in the SNc and TH- and DAT-positive fibers in CPu, both at 48 h and 7 days after the last MDMA administration. These results show that metformin is neuroprotective against the short- and long-lasting dopaminergic neurodegeneration induced by MDMA.     

Non-life-threatening sepsis: report of two cases

Streptococcus bovis is one of the nonenterococcal species included among the streptococci group D. It is part of the normal bowel flora in humans and animals, but it is also responsible for infectious diseases (10-15% of all cases of bacterial endocarditis). Many cases of bacteremia and metastatic abscesses (spleen, liver, soft tissues, bone, meninges, endocardium) caused by S. bovis were reported as associated with digestive tract diseases, mainly colonic disease, and, in particular colonic neoplasms, or chronic liver diseases. A role in carcinogenesis has been suggested for this microorganism. The authors report two cases of S. bovis sepsis, one associated with colonic neoplasm and the other with liver cirrhosis and gastric carcinoma. Discussion is focused on probable mechanisms that favor gastric colonization and systemic diffusion of S. bovis from the gut in patients with gastrointestinal neoplasms or chronic liver disease and provides clinical recommendations for patients with S. bovis infections.
