ABSTRACT

Background: SBIRT (Screening, Brief Intervention, and Referral to Treatment) is an effective early intervention approach for individuals with substance misuse. The purpose of this study was to determine if medical learners are more adept at learning a brief substance use intervention compared to non-medical learners (e.g., social work students). The dissemination of SBIRT training among many helping professions can increase service delivery for substance use problems. Methods: A total of 2,488 participants completed SBIRT training, representing 15 different disciplines and over 20 different institutions. General linear models and paired t-tests were used to investigate the effects of SBIRT training on changes in knowledge and attitude of alcohol and drug use and satisfaction. Results: There were no statistical differences in the change of satisfaction, knowledge, and attitude between medical and non-medical discipline participants. Both medical and non-medical participants had greater improvement in attitude and knowledge scores post-training. Similar improvements in attitude, knowledge, and satisfaction were observed in all the health-care discipline participants. Discussion: SBIRT skills may be transferable to disciplines including non-prescribing professionals (e.g., social work, nursing, physical therapy, rehabilitation science, and pharmacy). In an effort to expand treatment, health-care training institutions adopt SBIRT as a core competency for professional practice.

ABSTRACT

The aim of this study was to determine the presence of Chlamydia trachomatis (ChT) and Neisseria gonorrhoae (NG) in the genital tract of women with ectopic pregnancy and to compare the positive results with patients’ self-reported history of PID. Overall 40 women were eligible for the study. The samples for the ChT and NG Polymerase Chain-reaction (PCR) detection were obtained from the cervix, endometrium and fallopian tube. The results of testing for NG at all sites were negative as were the results from cervical testing for ChT. The prevalence of ChT in the upper genital tract was 12.5%. No statistically significant correlation was found between the positive cases and the previous signs of PID and laparoscopic findings. We found statistically significant relationship between signs of pelvic inflammation in a pacients’ history and histopathological findings of tubal inflammation. 12.5% prevalence of ChT confirms the ascending genital infection. There was no association between the positive PCR result and clinical history of pelvic inflammation.IMPACT STATEMENTWhat is already known on this subject? Pelvic inflammatory disease, Chlamydia trachomatis and Neisseria gonorrhoae infections are the main risks for ectopic pregnancy. Clinical history of PID and perioperative adhesions may suggest prior upper genital infection.What do the results of this study add? Chlamydia trachomatis positive PCR result can be found in the upper genital tract without the positivity of cervical smear in women with ectopic pregnancy. Our study is unique in assessing the endometrial biopsy for the presence of Chlamydia trachomatis and Neisseria gonorrhoae.What are the implications of these findings for future clinical practice and/or future clinical research? There is no statistically significant association between positive PCR result and clinical history of PID or pelvic adhesions found during laparoscopy for tubal pregnancy. Therefore there is no need for the preventive antibiotic treatment in patients with these findings.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the change in packed cell volume (PCV) and total protein following intramuscular preanesthetic sedation with one of three drug combinations in cats.

METHODS: Thirty client-owned cats were enrolled in this prospective, randomized, blinded, clinical study. A venous blood sample was obtained prior to administration of any sedation and PCV, total protein, electrolytes (Na⁺, K⁺, Cl^–, iCa²⁺), glucose and lactate were measured. Cats were randomly assigned to receive one of three intramuscular sedation protocols (n = 10 cats/protocol): methadone 0.2 mg/kg + acepromazine 0.02 mg/kg (MA), methadone 0.2 mg/kg + dexmedetomidine 5 µg/kg (MD) or methadone 0.2 mg/kg + midazolam 0.2 mg/kg + alfaxalone 2 mg/kg (MMA). Twenty-five minutes later, cats were assessed for level of sedation followed by another venous blood sampling to evaluate the same variables as above.

RESULTS: There were no significant differences in demographics (age, weight, sex) between groups. Level of sedation was significantly higher in MMA cats. Within groups, after premedication, PCV and hemoglobin significantly decreased in all groups, total protein significantly decreased in the MA and MMA groups and glucose significantly increased in the MD group. For electrolytes, statistical changes were not clinically relevant; Cl^– mean difference was significantly different between MA and MD; in the MD group Na⁺ and Cl^– significantly decreased and in the MMA group Cl^– significantly increased.

CONCLUSIONS AND RELEVANCE: All three sedation protocols caused significant decreases in PCV and hemoglobin in healthy cats.

ABSTRACT

OBJECTIVES: The aim of this study was to determine the feasibility of ultrasonographically measuring the caudal vena cava (CVC) at the subxiphoid view of healthy, lightly sedated cats in a standing position and lateral recumbency.

METHODS: This was a prospective, observational, experimental single-centre study. Twenty healthy research-purposed cats were enrolled. Two trained operators scanned each cat in two positions – standing and lateral recumbency – in a randomised order. CVC diameter was measured at the narrowest diameter during inspiration and at the widest diameter during expiration, at two anatomical locations along the CVC – where the CVC crosses the diaphragm (base) and 2 mm caudal to the diaphragm. The CVC collapsibility index (CVC-CI) was calculated for each site. Normalcy was assessed with a Shapiro-Wilk test. A one-way ANOVA with post-hoc Tukey’s test was used to compare inspiratory with expiratory values within and between groups. A paired t-test compared the CVC-CI between groups (P ⩽0.05 indicated statistical significance). Spearman’s correlation and Bland-Altman analysis assessed inter-operator variability.

RESULTS: All ultrasonographic data passed normalcy and were reported as mean ± SD. When compared with each other, inspiratory and expiratory values were statistically different for position, location and operator (all P <0.0001). There was no statistically significant difference between lateral recumbency or standing position for inspiratory, expiratory and CVC-CI values. Inter-operator variability was substantial, with operator 2 consistently obtaining smaller measurements than operator 1. The mean CVC-CI in lateral recumbency at the base was 24% for operator 1 and 37% for operator 2. For the same site in standing position, CVC-CI was 27% and 41% for operators 1 and 2, respectively.

CONCLUSIONS AND RELEVANCE: This pilot study demonstrates that it is possible to ultrasonographically measure the CVC diameter in both lateral recumbency and a standing position in healthy, lightly sedated cats. However, measurements obtained are operator dependent with variability between individuals. Further studies are needed to determine if ultrasonographic CVC assessment will prove helpful in estimating intravascular volume status in cats.

ABSTRACT

OBJECTIVES: The aim of this study was to compare the failure rate of two new generation pulse oximeters at different probe positions, and with and without vasoconstriction, in anaesthetised cats.

METHODS: This prospective clinical study included 103 cats in which the new generation pulse oximeters, the Rad-5 (Masimo) and EDAN H100N (EDAN), were evaluated. Premedication consisted of the vasoconstrictive drug combination butorphanol (0.2 mg/kg IV) and dexmedetomidine (5 µg/kg IV), or butorphanol only (0.2 mg/kg IV). Pulse oximeter failure rate at the tongue was compared between both groups. Pulse oximeter failure rate was also analysed at the alternative probe positions of the lip, pinna, knee fold and toe in the butorphanol group. Student’s t-test, Wilcoxon matched pairs signed rank test, Mann-Whitney U-test, Friedman test and χ² test were performed. A P value <0.05 was considered to be statistically significant.

RESULTS: Overall failure to achieve an adequate signal was 37.6% with the Masimo and 48.0% with the EDAN pulse oximeter (P <0.0001). At the standard probe position on the tongue, the Masimo failed in 4.5%, while the EDAN failed in 35.3% (P <0.0001). Vasoactive premedication increased the failure rate for the Masimo from 3.8% to 5.2% (P = 0.3414) and for the EDAN from 22.4% to 49.0% (P <0.0001). At the alternative probe positions of the lip and knee fold, failure rates for the Masimo were lower (39.7% and 81.4%) than with the EDAN (52.6% and 94.4%; P = 0.0231 and P = 0.0005, respectively), while the Masimo failed more often at the pinna (63.5%) than the EDAN (47.4%; P = 0.0044). At the alternative probe position of the toe, the failure rate for the Masimo (32.7%) was not different from the EDAN (38.5%; P = 0.7547).

CONCLUSIONS AND RELEVANCE: The Masimo pulse oximeter had lower signal failure rates at the standard probe position on the tongue and at 2/4 alternative probe positions. The standard probe position on the tongue had the lowest failure rate for both devices. Dexmedetomidine-induced vasoconstriction increased the failure rate for the EDAN but not for the Masimo pulse oximeter.

ABSTRACT

OBJECTIVE: To investigate the effect of atorvastatin on serum periostin level and blood eosinophil count in patients with asthma.

METHODS: Patients diagnosed with asthma were enrolled and randomised into an intervention or placebo group, to receive 40 mg atorvastatin or similar placebo, daily, for 8 weeks. Spirometry was performed at baseline, and at the end of weeks 4 and 8; patients also provided blood samples and completed an asthma control test (ACT) at baseline and at the end of week 8. Primary study outcomes were blood eosinophil count and serum periostin levels.

RESULTS: Eighty patients completed the study (40 per group). Mean ACT scores were similar between the intervention and placebo groups at baseline (17.95 ± 3.75 versus 17.98 ± 3.77, respectively), and improved in the intervention group (19.88 ± 3.28), but remained unchanged in the placebo group (18.6 ± 3.26) during the treatment period. No statistically significant differences in spirometric changes, blood eosinophil count or serum periostin levels were observed between the groups during the treatment period.

CONCLUSION: Spirometric parameters and inflammatory markers did not change significantly in response to atorvastatin treatment, and did not differ between the placebo and intervention groups.

ABSTRACT

BACKGROUND: Complex regional pain syndrome (CRPS) is a neuropathic pain condition with no universally recognised treatment. The study evaluates the efficacy of a therapeutic protocol consisting of oral citalopram and lidocaine injections in patients affected by CRPS.

METHODS: Between January 2010 and December 2014, 150 consecutive patients with CRPS were enrolled in the study and randomly assigned into three groups: group one – lidocaine injection and oral citalopram; group two – lidocaine injection and oral placebo; and group three – injective and oral placebo. The Impairment Sum Score (ISS) was used to assess the severity of CRPS before, as well as at regular intervals after treatment commenced. Statistical significance (p < 0.05) was determined by paired t-tests.

RESULTS: The combined treatment proved to be more effective (ISS 47.6 to 12.6) than local anaesthetic alone (ISS 47.5 to 21.5) and to placebo (ISS 47.2 to 29.9).

CONCLUSION: This study indicates that CRPS may be managed with well-tolerated association of oral citalopram and lidocaine injections.

ABSTRACT

BACKGROUND AND AIMS: The accurate differential diagnosis between autoimmune pancreatitis (AIP) and pancreatic ductal adenocarcinoma (PDAC) is clinically important. We aimed to determine significant MRI features for differentiating AIP from PDAC, including assessment of diffusion-weighted imaging (DWI).

METHODS: We performed a systematic search using three databases. The pooled diagnostic odds ratio was calculated using a bivariate random effects model to determine significant MRI features for differentiating AIP from PDAC. The pooled sensitivity and specificity were calculated. The qualitative systematic review for DWI assessment was performed.

RESULTS: Of nine studies (775 patients), multiple main pancreatic duct (MPD) strictures, absence of upstream marked MPD dilatation, peripancreatic rim, and duct penetration sign were significant MRI features for differentiating AIP from PDAC. Absence of MPD dilatation had the highest pooled sensitivity (87%, 95% CI=68-96%), whereas peripancreatic rim had the highest pooled specificity (100%, 95% CI=88-100%). Of 12 studies evaluating DWI, seven reported statistically significant differences in apparent diffusion coefficient (ADC) values between AIP and PDAC; however, four reported lower ADC values in AIP than in PDAC, but three reported the opposite result.

CONCLUSION: The four significant MRI features can be useful to differentiate AIP from PDAC, but DWI assessment might be limited.

ABSTRACT

PURPOSE: No therapeutic consensus has been established about proximal ruptures of the rectus femoris muscle. The objective of this literature review is to determine a therapeutic course of action.

METHODS: We conducted a literature review on the PubMed database using the following keywords (in French and English, respectively): “quadriceps/quadriceps”, “droit antérieur/rectus femoris”, “proximal/proximal”, “chirurgie/surgical”, “avulsion/avulsion”. We collected 266 articles, 36 of them were selected, which were related to our topic: proximal rupture of the anterior rectus femoris. Patients with a proximal rupture of the rectus femoris, minor or major patient of traumatic origin were included in this study. Patients injured at another lesion level, or non-traumatic lesions of the proximal rectus femoris (tendinitis without ruptures, tumor or others) were excluded. For each patient, the indications, the type of treatment and the functional result were analyzed, with the time to recovery and the level of recovery from sports and professional activities (same sport/profession or not, same level or not) as the main criterion of judgment. Fisher exact test was used for statistical comparison.

RESULTS: The aims of conservative treatment are to be pain free for the patient, to fight hematoma and to rehabilitate the injury as quickly as possible. The surgical techniques are varied, with most consisting of either a reinsertion of the musculo-tendon stump or a resection of the scar tissue with myo-tendino-aponeurotic suture in place. The functional results are good for the majority of the treatments proposed, but the conservative treatment has a shorter recovery time (3 months vs. 4 months for the best surgical results). Highly displaced bone avulsion is the only indication for first-line surgical treatment.

CONSLUSION: The main disadvantage of conservative treatment is the risk of residual pain beyond 3 months (10%), justifying an MRI to guide secondary surgical treatment. We propose a treatment plan for proximal rupture of the proximal rectus femoris rupture.

ABSTRACT

INTRODUCTION: Learning disability has a significant relevance and can generate negative social impacts on the future of an individual if not corrected in time. Phoniatrics is an area of otorhinolaryngology responsible for evaluating, diagnosing, and referring these cases for therapy and/or complementing the multidisciplinary diagnosis.

OBJECTIVE: To evaluate in school-aged children the association between the application of a set of tests used in the phoniatric assessment and complaints of academic difficulties. To identify which tests would show the main association with academic performance when applied individually.

METHODS: Blind, cross-sectional study, subdivided into 4 stages. In the 1st stage, 66 children in the third year of elementary school were submitted to the set of tests of skills applied by the phoniatrician; in the 2nd stage, the physician asked the educators about complaints of academic difficulties regarding the students; in the 3rd stage the students’ Portuguese language school grade was obtained and in the 4th stage an analysis was made between the data.

RESULTS: The educator identified complaints of academic difficulties in 27.2% of the 66 students. There was a statistically significant association between academic difficulties and the following tests of skills: dictation of words and pseudowords, dictation of words, dictation of pseudowords, rhyming, phonemic synthesis, and in the reading test; fluency, intonation and comprehension of the text and morals were analyzed in the reading test. In the multivariate logistic regression analysis, the tests selected to comprise the final model, showing greater association with the academic difficulty complaint were: dictation of words, intonation in reading and comprehension of the morals of the story.

CONCLUSION: The tests identified as the most relevant in identifying academic difficulties were dictation of words, intonation in reading and comprehension of the morals of the story. However, the other tests that were part of the phoniatric consultation allowed the observation of the individual and their functioning abilities, leading to a better assessment of the case, regarding aspects not directly related to the pedagogical one.
