ABSTRACT

OBJECTIVE: Primary aim; to determine the feasibility of implementation of the INTERMED Self-Assessment (IM-SA) in adult patients scheduled for total knee arthroplasty (TKA). Secondary aim; to measure biopsychosocial complexity, referral to psychiatry or psychology in cases of complexity and to gain insight into the relation between biopsychosocial complexity and length of stay (LOS), method of discharge (MOD) and polypharmacy. METHODS: A feasibility study was conducted with 76 participants in a general hospital in the Netherlands. Feasibility was determined by the number of completed questionnaires, time spent completing the questionnaire and the attitude of staff and patients towards the IM-SA. A cut off point ≥19 on the IM-SA was used to determine the prevalence of biopsychosocial complexity. A case file study was performed to check if referral to psychiatry or psychology had taken place. The Spearman's Rank Correlation Coefficient or Phi was used to determine if there was a relation between biopsychosocial complexity and LOS, MOD and polypharmacy. RESULTS: All participants completed the IM-SA. The average time spent completing the questionnaire was 11.46 min (SD 5.74). The attitude towards the IM-SA was positive. The prevalence of biopsychosocial complexity was 11.84%. Referral to psychiatry or psychology did not take place. There was no relation between complexity and LOS (Spearman's rho (r) = 0.079, p = 0.499, MOD (Phi = 0.169, p = 0.173) and polypharmacy (Phi = 0.007, p = 0.953). CONCLUSION: Biopsychosocial complexity can be identified in TKA patients during the pre-operative phase by using the IM-SA. Implementation of the IM-SA in a Dutch general hospital is feasible.

ABSTRACT

Neospora caninum is a protozoan parasite that causes abortion, perinatal mortality, and subfertility in cattle worldwide. Despite the presence of the DNA of the parasite in semen of infected bulls, the effect on semen quality has not been extensively studied. This study aimed to investigate the effect of a natural Neospora caninum infection on fresh and frozen semen quality parameters in Belgian Blue bulls. Two hundred and fourteen bulls were serologically screened with an indirect ELISA-test specific for anti-Neospora caninum antibodies, every two months during one year. In addition to serological screening, semen was collected twice weekly using an artificial vagina. The following semen quality parameters were assessed: ejaculate volume, concentration, total motility of fresh semen samples, as well as morphology, total and progressive motility for frozen/thawed semen samples. Bulls were semen sampled throughout the whole year, but only semen samples of bulls that had six consecutive positive or negative ELISA-test results were included in our dataset (n = 98). Generalized linear and binomial mixed models were used for statistical analysis of each outcome variable. In these models the explanatory variables were defined as: age, barn location, mean Temperature Humidity Index (THI) during sperm production (14-42 days before sampling), maximum daily THI at collection, season of sperm production, season at collection and the Neospora caninum antibody test results. Initially, individual explanatory variables were tested in univariable models for each outcome variable. Akaike information criterion (AIC) values were used to select explanatory variables to build a multivariable model, where the Neospora caninum test result was forced in all models. The present study reveals an overall apparent seroprevalence of Neospora caninum of 9,2% in the study population. No significant associations were detected between natural neosporosis, substantiated by ELISA-antibody levels, and any of our tested outcome variables on fresh and frozen/thawed semen samples. Based on the results of the present study, we conclude that Neospora caninum seropositive bulls do not have lower semen quality parameters compared with seronegative bulls.

ABSTRACT

BACKGROUND: Fear of movement (kinesiophobia) after an acute cardiac hospitalization (ACH) is associated with reduced physical activity (PA) and non-adherence to cardiac rehabilitation (CR). PURPOSE: To investigate which factors are related to kinesiophobia after an ACH, and to investigate the support needs of patients in relation to PA and the uptake of CR. METHODS: Patients were included 2-3 weeks after hospital discharge for ACH. The level of kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK-NL Heart). A score of > 28 points is defined as 'high levels of kinesiophobia' (HighKin) and ≤ 28 as 'low levels of kinesiophobia' (LowKin). Patients were invited to participate in a semi-structured interview with the fear avoidance model (FAM) as theoretical framework. Interviews continued until data-saturation was reached. All interviews were analyzed with an inductive content analysis. RESULTS: Data-saturation was reached after 16 participants (median age 65) were included in this study after an ACH. HighKin were diagnosed in seven patients. HighKin were related to: (1) disrupted healthcare process, (2) negative beliefs and attitudes concerning PA. LowKin were related to: (1) understanding the necessity of PA, (2) experiencing social support. Patients formulated 'tailored information and support from a health care provider' as most important need after hospital discharge. CONCLUSION: This study adds to the knowledge of factors related to kinesiophobia and its influence on PA and the uptake of CR. These findings should be further validated in future studies and can be used to develop early interventions to prevent or treat kinesiophobia and stimulate the uptake of CR.

ABSTRACT

OBJECTIVES: To determine the risk of first unplanned all-cause readmission and mortality of patients ≥70 years with acute myocardial infarction (AMI) or heart failure (HF) and to explore which effects of baseline risk factors vary over time. METHODS: A retrospective cohort study was performed on hospital and mortality data (2008) from Statistics Netherlands including 5,175 (AMI) and 9,837 (HF) patients. We calculated cumulative weekly incidences for first unplanned all-cause readmission and mortality during 6 months post-discharge and explored patient characteristics associated with these events. RESULTS: At 6 months, 20.4% and 9.9% (AMI) and 24.6% and 22.4% (HF) of patients had been readmitted or had died, respectively. The highest incidences were found in week 1. An increased risk for 14-day mortality after AMI was observed in patients who lived alone (hazard ratio (HR) 1.57, 95% confidence interval (CI) 1.01-2.44) and within 30 and 42 days in patients with a Charlson Comorbidity Index ≥3. In HF patients, increased risks for readmissions within 7, 30 and 42 days were found for a Charlson Comorbidity Index ≥3 and within 42 days for patients with an admission in the previous 6 months (HR 1.42, 95% CI 1.12-1.80). Non-native Dutch HF patients had an increased risk of 14-day mortality (HR 1.74, 95% CI 1.09-2.78). CONCLUSION: The risk of unplanned readmission and mortality in older AMI and HF patients was highest in the 1st week post-discharge, and the effect of some risk factors changed over time. Transitional care interventions need to be provided as soon as possible to prevent early readmission and mortality.

ABSTRACT

BACKGROUND: After hospitalization for cardiac disease, older patients are at high risk of readmission and death. Although geriatric conditions increase this risk, treatment of older cardiac patients is limited to the management of cardiac diseases. The aim of this study is to investigate if unplanned hospital readmission and mortality can be reduced by the Cardiac Care Bridge transitional care program (CCB program) that integrates case management, disease management and home-based cardiac rehabilitation. METHODS: In a randomized trial on patient level, 500 eligible patients ≥ 70 years and at high risk of readmission and mortality will be enrolled in six hospitals in the Netherlands. Included patients will receive a Comprehensive Geriatric Assessment (CGA) at admission. Randomization with stratified blocks will be used with pre-stratification by study site and cognitive status based on the Mini-Mental State Examination (15-23 vs ≥ 24). Patients enrolled in the intervention group will receive a CGA-based integrated care plan, a face-to-face handover with the community care registered nurse (CCRN) before discharge and four home visits post-discharge. The CCRNs collaborate with physical therapists, who will perform home-based cardiac rehabilitation and with a pharmacist who advices the CCRNs in medication management The control group will receive care as usual. The primary outcome is the incidence of first all-cause unplanned readmission or mortality within 6 months post-randomization. Secondary outcomes at three, six and 12 months after randomization are physical functioning, functional capacity, depression, anxiety, medication adherence, health-related quality of life, healthcare utilization and care giver burden. DISCUSSION: This study will provide new knowledge on the effectiveness of the integration of geriatric and cardiac care. TRIAL REGISTRATION: NTR6316 . Date of registration: April 6, 2017.

ABSTRACT

AIM: To explore which factors are associated with psychological insulin resistance in insulin-naive patients with Type 2 diabetes in primary care. METHODS: A sample of 101 insulin-naive patients with Type 2 diabetes completed self-administered questionnaires including demographic and clinical characteristics, the Insulin Treatment Appraisal Scale and the Center for Epidemiological Studies Depression scale. Psychological insulin resistance was denoted by negative appraisal of insulin (Insulin Treatment Appraisal Scale). RESULTS: Thirty-nine per cent of the sample were unwilling to accept insulin therapy. Unwilling participants perceived taking insulin more often as a failure to control their diabetes with tablets or lifestyle compared with willing participants (59 vs. 33%), unwilling participants were more reluctant to accept the responsibilities of everyday management of insulin therapy (49 vs. 24%). Multiple linear regression analysis revealed that depression and objection to lifelong insulin therapy were independently associated with psychological insulin resistance. CONCLUSIONS: In this study in primary care, depression and objection to lifelong insulin therapy are associated with psychological insulin resistance. Analysis of the objection to the indefiniteness of insulin therapy showed a sense of limitation of daily life and loss of independence that should not be underestimated. Insulin should be offered as a means to improve health as this might facilitate the acceptance of insulin therapy.

ABSTRACT

We report 2 cases of children who developed a complete atrioventricular block following an infection, varicella without complication initially in the first case and Mycoplasma pneumoniae pneumopathy in the second case, in which a first-degree congenital heart block was diagnosed on this occasion. In case 1, the treatment consisted in oral corticosteroids leading to the recovery of sinus rhythm; the course was unfavorable in the second case and required a permanent pacemaker. This cardiac complication of bacterial or viral infection is rare in children but evolves to permanent conduction disturbance in 1/3 of the cases. It is important to detect this disorder, which is feasible simply by a clinical examination and an electrocardiogram.

ABSTRACT

Cocaine abuse induces severe cardiomyopathy. To investigate the molecular effects of acute and prolonged administration of cocaine, mRNAs encoding markers of either mechanical overload, as atrial natriuretic factor (ANF) and alpha- and beta-myosin heavy chains, or fibrosis as type I and III procollagens, were quantitated in the left ventricle of rats 4 h after one injection of cocaine (40 mg/kg, n = 7), or 14 (n = 15) and 28 days (n = 10) after chronic infusion of cocaine (40 mg/kg per day). Plasma cocaine and benzylecgonine concentrations were both significantly augmented during the infusion while plasma levels of triiodothyronine and thyroxine were lowered. Acute injection of cocaine induced ANF gene expression. Cocaine treatment during 28 days resulted in left ventricular hypertrophy (+ 20% after 24 days, P < 0.05) with normal blood pressure, associated with an accumulation of mRNAs encoding ANF and type I and III collagens (+66% and +55%, P < 0.05). Such a chronic treatment also induced a shift from the alpha- to the beta-myosin heavy chain gene expression (-40% and +50%, P < 0.05). In conclusion, cocaine activates markers of both hemodynamic overload and fibrosis. Such an activation may result from direct and/or indirect effects of the drug such as myocardial ischemia, mechanical overload and/or hypothyroidism.

ABSTRACT

Cocaine exerts in the rat an inhibitory effect on the baroreflex induced by bilateral clamping of the carotid arteries. The present series of experiments were designed to test the effectiveness of cocaine antidotes on this deregulation of the baroreflex. Sprague-Dawley rats were fitted under pentobarbital anesthesia with a catheter in the caudal artery, and their carotid arteries were exposed. The pressure signal from the caudal artery was treated on line by a microcomputer for continuous display of blood pressure and heart rate measurements. The animals were administered intraperitoneally either 50 mg cocaine or an equal volume of saline. Five minutes later, they were administered either saline or proven antidotes to cocaine (diltiazem, nicardipine, enzyme converting inhibitor [ECI], enalaprilat associated with diazepam). After 2 min, stimulation of the baroreceptor was performed by bilateral clamping of the two carotids for a period of 2 min. The measures of the maximal variation in systolic pressure before and after clamping indicated a significant difference between saline and cocaine treated animals (P < 0.05), with the former displaying a much greater increment in blood pressure after clamping. The cocaine-treated animals, administered diltiazem, nicardipine, and ECI associated with diazepam, presented after clamping of the carotid arteries a normal baroreflex with increments in blood pressure not significantly different from those occurring in the animals receiving saline, but significantly different from those administered cocaine only (P < 0.05). Baroreflex deregulation by cocaine may also be restored by an angiotensin II receptor antagonist. The possible role of this peptide in mediating in part baroreflex activity is discussed.

ABSTRACT

Sprague-Dawley rats were fitted under pentobarbital anesthesia with a catheter in the caudal artery and their carotid arteries were exposed. The pressure signal from the caudal artery was treated on line by a microcomputer for continuous display of blood pressure and heart rate measurements. The animals were administered intraperitoneally either 50 mg/kg of cocaine or an equal volume of saline. Five minutes later, stimulation of the baroreflex was performed by bilateral clamping of the two carotids for a period of 2 min. The same maneuver was repeated at 12, 24, and 31 min. Analysis of variance for repeated measures indicated that before carotid artery clamping, there was no significant difference between blood pressure measurements of the saline- and cocaine-treated groups. A two-factor analysis of variance of the repeated measures of the maximal variation in systolic pressure after each clamping showed a significant difference between control and cocaine-administered groups (P < 0.001), with the former displaying a much greater increment in blood pressure after carotid clamping. Cocaine exerts an inhibitory effect on the baroreflex that may be mediated through the increased angiotension II caused by the alkaloid.

ABSTRACT

The pathophysiological effects of marijuana smoke and its constituent cannabinoids were reported first from in-vitro and in-vivo experimental studies. Marijuana smoke is mutagenic in the Ames test and in tissue culture and cannabinoids inhibit biosynthesis of macromolecules. In animals, marijuana or delta 9-tetrahydrocannabinol (THC), the intoxicating material it contains, produces symptoms of neurobehavioural toxicity, disrupts all phases of gonadal or reproductive function, and is fetotoxic. Smoking marijuana can lead to symptoms of airway obstruction as well as squamous metaplasia. Clinical manifestations of pathophysiology due to marijuana smoking are now being reported. These include: long-term impairment of memory in adolescents; prolonged impairment of psychomotor performance; a sixfold increase in the incidence of schizophrenia; cancer of mouth, jaw, tongue and lung in 19-30 year olds; fetotoxicity; and non-lymphoblastic leukemia in children of marijuana-smoking mothers.

ABSTRACT

Ethyl alcohol increases significantly the lethality of cocaine intoxication in the rat. This lethality is not modified by nicardipine or flunarizine, antidotes to cocaine, and might be due to the formation of a newly identified active metabolite cocaethylene. In addition alcohol like cocaine inhibits the baro receptor reflex.

ABSTRACT

Calcium entry modulators were tested as antidotes to imipramine lethal toxicity. 42 rats were administered intraperitoneally 85 mg/kg of imipramine. In 6 control rats, hypotension and bradycardia were observed. Survival time was 15' +/- 5'. Survival time of rats treated with intraarterial nitrendipine was 21' +/- 11'. Survival time of 5 out of 6 rats treated by intraarterial verapamil or diltiazem was respectively 19'00" +/- 14'30" and 40'30" +/- 32'00". 5 out of 6 rats treated by intraarterial nimodipine, as well as all of the rats treated by flunarizine or nicardipine survived and were alive and active 48 hours later. Intoxication with imipramine may induce life threatening complications for which there are no specific medication. Nicardipine might be considered in the treatment of acute poisoning by imipramine and related tricyclic compounds.

ABSTRACT

Mice were given 10 to 100 mg/kg by stomach tube of delta 9-tetrahydrocannabinol (THC) in a single dose or for 4 consecutive days. [3H]Thymidine or [3H]glucosamine was given 3 or 24 hr before sacrifice. Enterocytes were isolated, and the incorporation of radioactivity into the acid insoluble fraction was measured. THC significantly inhibits in a dose-related fashion (from 10 to 90%) in vivo enterocyte metabolism. This inhibition is found in all enterocytes whatever their position in the intestinal tract; it is also independent of the state of differentiation of enterocytes. After a single ingestion of THC, crypt cells which synthesize DNA incorporate 37 to 45% less thymidine, and villus cells, which synthesize important amounts of glycoproteins, incorporate 15 to 39% less glucosamine. After 4 days of THC administration, the inhibition of thymidine incorporation is even more significant (up to 88%).

ABSTRACT

Delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) have antagonistic effects on the isolated perfused heart in a Langendorff preparation. THC in concentration of 2 X 10(-6) to 10(-5)M induces an increased frequency with a maximum at 8 X 10(-6)M, and at the same time a decrease in contractile force and coronary flow. CBD at similar concentrations does not affect heart rate, while increasing contractile force and coronary flow. These effects of CBD prevail when this cannabinoid is administered simultaneously with THC.
