Maximum voluntary molar bite force in subjects with normal occlusion

The aims of this investigation were to determine whether stabilization of maximum voluntary bite force (MVBF) occurs between 15 and 18 years of age in subjects with a normal occlusion, and to assess the influence of gender, body mass index (BMI), morphological occlusion, and jaw function measured by the number of occlusal contacts, overjet, overbite, maximal mouth opening, mandibular deflection during opening, sagittal slide between the retruded contact position and the intercuspal position, and number of dental restorations. The sample comprised 60 Caucasian subjects aged 15 (15 males and 15 females) and 18 (14 males and 16 females) years with a neutral occlusion, balanced facial profile, and absence of a previous orthodontic history. Bite force measurements were undertaken using a portable occlusal force gauge on both the left and the right sides of the jaw in the first molar region during maximal clenching. Two independent samples t-tests and multiple regression were used for statistical analysis. MVBFs were age and gender related (P<0.05). Males showed a significant increase in bite force between 15 and 18 years of age (P=0.002), but gender differences were significant only in the 18-year-olds (P=0.003). In subjects with a neutral occlusion, MVBF could best be predicted using multiple regression from age and gender. The regression model accounted for 31.3 percent of the variance in MVBF (P=0.031), with gender contributing 17.9 percent and age 7.9 percent. Morphological occlusion, jaw function, and BMI explained the remaining 5.5 percent of variance. While controlling for all other parameters, the independent contribution of gender to the prediction of MVBF was 16.2 percent, age 6 percent, number of occlusal contacts 3.2 percent, and BMI 1.3 percent.     

Clinical knowledge of community pharmacists in Croatia for detecting drug-related problems

Background Drug-related problems (DRPs) interfere with patient’s health outcomes and have a negative impact on healthcare resources. Successful management of DRPs is an essential part of pharmaceutical care. Pharmacists should have adequate clinical knowledge in order to effectively implement pharmaceutical care and manage DRPs. Objective To determine the clinical knowledge of community pharmacists in Croatia to detect and resolve DRPs. Method A sample of 302 community pharmacists have anonymously and voluntarily completed the validated survey-based clinical knowledge measurement tool. For each completed survey, all statements were scored individually, and a total score was calculated. The lowest possible total score was 0 and the highest was 80. Higher survey score indicates a higher level of clinical knowledge to detect and resolve a DRP. Results All community pharmacists had a mean score of 45.5 ± 8.6, while pharmacists from a pharmacy chain with mandatory education had a higher mean score of 50.2 ± 6.5. Multivariate linear regression revealed that only additional education (β = 0.272, p < 0.001) is associated with a higher mean score, while age and gender have no influence on the survey score. Conclusion Additional education of community pharmacists could increase their clinical knowledge to detect and resolve DRPs.     

Neonatal risk mortality scores as predictors for health-related quality of life of infants treated in NICU: a prospective cross-sectional study

Purpose

To determine the relationship of Apgar scores, gestational age and neonatal risk mortality scores to health-related quality of life (HRQoL) for infants at the age of 8 months treated after birth in neonatal intensive care unit (NICU).

Methods

All surviving infants treated in two-third level NICUs in Rijeka, Croatia (from August 2013 to August 2014) were included in this prospective, cross-sectional study. For all neonates, the Score for Neonatal Acute Physiology (SNAP), SNAP with Perinatal Extension (SNAP-PE) and their simplified modifications (SNAP II and SNAP-PE II) were calculated. At the corrected age of 8 months, the Pediatric Quality of Life Questionnaire (PedsQL)—infant scale—was completed by parents of surviving infants. Multiple regression analysis was performed in order to assess the value of neonatal risk mortality scores, Apgar scores and gestational age as possible predictors of HRQoL, measured by questionnaire score.

Results

A strong correlation has been found between SNAP and 5-min Apgar scores to HRQoL. A positive correlation was also found between gestational age and HRQoL.

Conclusion

SNAP and 5-min Apgar scores are important outcome indicators, can aid clinicians’ and parents’ decision making on the benefits and burdens of acute medical interventions and help determine quantities of medical treatment. Educated medical staff, effective and efficient medical treatment and a high quality of care which prevent adverse events in the first minute of life should be a priority in efforts to improve the future quality of life.

     

Preoperative assessment of ovarian tumors by CA 125 measurement and transvaginal color Doppler ultrasound

The accuracy of combined use of serum CA 125 and transvaginal color Doppler for preoperative assessment of ovarian lesions in premenopausal patients was evaluated. Seventy-six ovarian lesions were analyzed the day before surgery using transvaginal color Doppler ultrasound. On the same day, serum CA 125 was measured in each patient. A novel index is proposed for the detection of ovarian malignancy combining resistance index (RI) obtained from newly formed vessels within the ovarian lesion and serum CA 125 level: (RI/CA 125) x 100. Values below the cut-off value of 1.5 were associated with a high risk of ovarian malignancy. Assessment of ovarian lesions by the novel index had a sensitivity and specificity of 94.44% and 100%, while positive and negative predictive values were 100% and 98.31%, respectively. The best prediction of ovarian malignancy was achieved by a combined use of transvaginal color Doppler ultrasound and serum CA 125 in the form of index: (RI/CA 125) x 100.     

Antihypertensive effect of metoprolol in diuretic-treated,mild primary hypertension

Metoprolol tartrate was administered to 41 patients with mild essential hypertension already treated with a diuretic for a period of 2 weeks. In the majority of those patients, other step 2 antihypertensive agents either failed to control high blood pressure or caused adverse reactions. All other antihypertensive agents except diuretics were discontinued during the 2-week wash-out period. Patients with a diastolic blood pressure of 95 to 104 mmHg (inclusive) received oral metoprolol at a dose of 50mg twice daily for 2 weeks. Subsequently, metoprolol titration was individualized on a bi-weekly basis until either the diastolic blood pressure was = 90 mmHg and/or a maximal daily dose of 300mg of metroprolol was reached. The analysis of efficacy and safety was done for a total period of 14 weeks. Diastolic blood pressure and heart rates were significantly reduced (P≤0.05) in all treatment groups. Minor adverse reactions such as mild fatigue in 11 patients, nervousness in 2, and leg cramps in 2 patients were reported. Transient skin rash, dizziness, headache, chest pain, insomnia, and cold extremities were also reported in one patient each. It is concluded from the present study that metropolol (in twice daily dose) in combination with a diuretic is safe, effective, and well tolerated in the treatment of mild hypertension.
