Healthcare professionals and students' knowledge on termination of pregnancy legislation and clinical practice: A systematic review.

BACKGROUND: Legal and safe termination of pregnancy (TOP) has long been recognised as an important public health issue internationally. Healthcare professionals (HCPs) and students have a key role within TOP services, and it is crucial that they have sufficient understanding of laws, guidelines and clinical practice to facilitate safe and effective care. The current systematic review aims to study the level of knowledge of both HCPs and students on TOP legislation, methods and procedures and potential associated complications. METHODS: PubMed, Embase, Scopus and EBSCOhost were searched for peer-reviewed studies published until July 2020. After initial selection, 239 articles were screened in full and 31 studies (qualitative and quantitative) were included. A narrative review and synthesis of the findings was completed. MAIN FINDINGS: Poor knowledge on TOP legislation and clinical practice was reported for HCPs and students. The main issues identified included limited awareness of specific circumstances for legal TOP and poor understanding of methods and medical regimens recommended. Overall, education/training, experience in provision of TOP and receiving reminders of legislation were the main factors associated with increased levels of knowledge. CONCLUSION: HCPs must be fully aware of the clinical practice and circumstances in which TOP is legal in their country/region so adequate provision of this service is ensured. This study highlighted the importance of involving and promoting participation of HCPs and students in the provision of TOP services. A clear need and desire for staff education and training on TOP was shown. Adequate training allows preparation of current and future HCPs to provide respectful and compassionate care.

Trends in prescriptions for glaucoma and ocular hypertension in France between 2014 and 2019.

PURPOSE: To explore the national trend in prescriptions for glaucoma and ocular hypertension (OHT) in France between 2014 and 2019. METHODS: This is a retrospective descriptive study based on prescription data from the Primary Health Insurance Fund databases. All patients with a social security number who received one or more glaucoma/OHT prescriptions between 2014 and 2019 were identified. Figures for 2020 are not yet available as of the date of submission of this article. Demographic characteristics from Common Classification of Medical Acts information and from National Institute of Statistics and Economic Studies were analyzed. The data analysis was carried out using the R version 3.6.2.software from the available databases of the Information Systems Medicalization Program. RESULTS: Our results suggest an increase in the number of patients treated with glaucoma drugs, which cannot be explained simply by demographic growth. There is also a change in drug prescription habits, both in the class of medication used and in the use of fixed combinations. We also note the increasing use of SLT (Selective Laser Trabeculoplasty), a relatively newer tool in the therapeutic arsenal. Over the same time period, demographic characteristics remained stable; age and sex distribution for each year remained constant. In addition, the phenomenon of poor therapeutic compliance, which we attempted to explore, remained stable. DISCUSSION: This study updates the French epidemiologic data available on prescriptions for glaucoma and ocular hypertension, a true public health concern. CONCLUSION: On the one hand, prescribing practices have evolved over the study period. On the other hand, the number of patients treated has increased faster than the growth of the French population over the same period. These findings are consistent with trends observed in previous studies.

Development of a PCR assay for diagnosis of Pneumocystis carinii pneumonia based on amplification of the multicopy major surface glycoprotein gene family.

We have evaluated a PCR technique using primers based on Pneumocystis carinii major surface glycoprotein (MSG) genes, a multicopy gene family, for utility in detection of P. carinii in BAL and oropharyngeal samples obtained from immunosuppressed patients. These primers were able to detect P. carinii DNA in as little as 16 fg of genomic DNA. PCR using MSG primers detected P. carinii DNA in 7 smear-positive BAL samples (100% sensitivity), and found no P. carinii DNA in 12 smear-negative BAL samples (100% specificity). Mitochondrial ribosomal RNA (mrRNA) primers, commonly used in PCR studies of PCP, detected P. carinii in six of seven positive samples (85.7% sensitivity) and none of 12 were negative samples (100% specificity). Diagnosis of PCP by amplification of 81 oropharyngeal samples using MSG primers had a 50% sensitivity (4/8) and 96% specificity (70/73). PCR with mrRNA primers was 37.5% sensitive (3/8) and 100% specific (73/73). All three false-positive MSG results showed a very low intensity on Southern hybridization. PCR using MSG gene primers should prove valuable in the diagnosis of PCP.

Evaluation of two rapid assays for detection of Clostridium difficile toxin A in stool specimens.

Rapid laboratory diagnosis of Clostridium difficile-associated diarrhea (CDAD) is highly desirable in the setting of hospital cost containment. We tested 654 stool specimens to compare the performance of two assays for rapid detection of toxin A, the Immunocard Toxin A test (Meridian Diagnostics, Inc.) and the Culturette Brand Toxin CD enzyme immunoassay (EIA) (Becton Dickinson Microbiology Systems), with a cytotoxin assay (Cytotoxi Test; Advanced Clinical Diagnostics) and culture on cycloserine-cefoxitin-fructose agar followed by determination of the production of toxins A and B. A chart review was performed for patients whose stool specimens provided positive results on one to three of the assays. With the "gold standard" of all four assays positive or chart review evidence of CDAD, 97 (14.8%) stool specimens were positive by one or more assays and 557 (85.2%) were negative by all methods. Total agreement for all assays was 90.5% (592 of 654). The sensitivity, specificity, positive predictive value, and negative predictive value for toxigenic culture were 94.7, 98.6, 87.1, and 99.5%, respectively, for toxigenic culture; 87.7, 98.6, 86.2, and 98.8%, respectively, for the cytotoxin assay; 71.9, 99.3, 91.1, and 97.3%, respectively, for the Immunocard; and 68.4, 99.1, 88.6, and 96.9%, respectively, for the Culturette EIA. While easy to perform and highly specific, these rapid assays do not appear to be sufficient for accurate diagnosis of CDAD.

Correlation of in vitro susceptibility results for amoxicillin-clavulanate and ampicillin-sulbactam tested against Escherichia coli.

The results of amoxicillin-clavulanate (AUG) and ampicillin-sulbactam (A/S) susceptibility testing by three different susceptibility testing methods, the MicroScan, Etest, and Kirby-Bauer methods, for 61 consecutive isolates of ampicillin-resistant Escherichia coli from different patients were compared. There was poor correlation of results for the two agents, the most and least marked discrepancies being observed by the MicroScan method (86.9% susceptible to AUG and 4.9% susceptible to A/S) and the Kirby-Bauer method (39.4% susceptible to AUG and 32.8% susceptible to A/S), respectively. More organisms were susceptible to AUG than A/S, regardless of the susceptibility testing methodology. The results from a College of American Pathologists survey with one E. coli isolate tested at different institutions also indicated greater susceptibility to AUG than to A/S. These agents are thought to be equally efficacious clinically. The discrepancies observed among methods for each antimicrobial inhibitor combination and the discrepancies observed between the two agents by each testing method suggest that the breakpoints for these agents need to be reevaluated.

Tuberculosis due to Mycobacterium bovis in humans in the south-west region of Ireland: is there a relationship with infection prevalence in cattle?

OBJECTIVE: To compare the incidence of tuberculosis due to Mycobacterium bovis in humans to the prevalence of M. bovis infection in cattle in south-west Ireland and discuss possible links between them. SETTING: In the south-west region of Ireland, a mixed urban and rural community (pop. 536,000), there is a residuum of human tuberculosis caused by M. bovis. METHODS: A retrospective analysis of the incidence of culture-positive M. bovis disease in humans in south-west Ireland from 1983 to 1994 and of the results of tuberculin testing in cattle from 1978 to 1994 for the same region. RESULTS: One to five cases of human tuberculosis due to M. bovis were recorded per year while the overall prevalence of bovine infection fell gradually during the period of study from 467 tuberculin-positive animals per 100,000 cattle tested in 1983 to 158 per 100,000 in 1994. CONCLUSION: The low incidence plateau of human tuberculosis due to M. bovis together with the decline in prevalence of animal infection in the overall period studied suggest a cut-off in the animal to human chain of infection at two points; the animal source and the ingestion of (now pasteurized) milk. This would suggest that disease in humans is now due to reactivation of previous foci of infection which were acquired when milk pasteurization was not compulsory. Based on this, we would anticipate a further reduction and possible elimination of human tuberculosis due to M. bovis in this region in the next 10-15 years.

Human Mycobacterium bovis infection in the south-west of Ireland 1983-1992: a comparison with M. tuberculosis.

Epidemiological and bacteriological aspects of human Mycobacterium bovis disease were investigated in south-west Ireland (counties Cork & Kerry, population 536,000) over the years 1983-92 inclusive and compared to M. tuberculosis. Results showed a small, stable incidence of culture positive M. bovis human disease, mean annual incidence 0.56 per 100,000 population compared to a higher but declining incidence of culture positive M. tuberculosis (15.3 per 100,000 in 1983, 9.0 per 100,000 in 1992). Male patients were the majority, 63.4 per cent of M. bovis; 62.4% of M. tuberculosis (p = 0.03). Fifty three per cent of M. bovis cases (n = 30) were pulmonary, compared to 85% of M. tuberculosis (n = 626; p = 0.0001). M. bovis patients were older (p = 0.02), mean age 58.4 years (SD 18.9) compared to 48.5 (SD 22.2). The mycobacterial smear positive rate was similar in both groups taken as a whole. No rural-urban difference in incidence was found in either disease, suggesting in the case of M. bovis initial infection in childhood via contaminated milk in the pre-pasteurisation era.

Comparison of 99mTc infecton imaging with radiolabelled white-cell imaging in the evaluation of bacterial infection.

BACKGROUND: Bacterial infection can pose a substantial diagnostic dilemma. Techniques involving radiolabelled leucocytes can pinpoint the site of inflammation. However, previous radiolabelling techniques have failed to distinguish between bacterial-mediated infection and non-bacterial inflammation. To overcome this difficulty, we have studied a radiopharmaceutical, technetium-99m (99mTc) Infecton, which is based on the antibiotic ciprofloxacin. METHODS: We used this agent to image bacterial infection in 56 patients (one twice) with known or suspected sites of infection. We then compared the imaging results of these patients with those from a radiolabelled leucocyte study. FINDINGS: The concordance rate was 68% (39 out of 57 images). In 18 discordant results 99mTc Infecton was correctly positive in 8 out of 9 positive studies and correctly negative in 4 out of 9 negative studies. 4 out of 5 of the falsely negative studies were in patients who had taken antibiotics for over 7 days. We found that 99mTc Infecton gave better imaging results than radiolabelled leucocytes. Comparison between 99mTc Infecton and leucocyte imaging gave sensitivities of 84% and 81%, and specificities of 96% and 77%, respectively. INTERPRETATION: We believe that the specificity 99mTc Infecton confers for bacterial infection and its ease of administration are the main advantages of this new agent.

Colorimetric detection of heat-labile toxin-encoding gene of enterotoxigenic Escherichia coli by PCR.

In the developing world, enterotoxigenic Escherichia coli (ETEC) strains which produce enterotoxins are a significant cause of morbidity and mortality. Heat-labile (LT) toxin PCR detection methods have been described, but they have limited applications in a routine laboratory setting. A colorimetric DNA method for the rapid amplification and detection of the LT toxin gene in ETEC strains is described. Target amplification together with colorimetric detection would overcome many of the limitations of conventional PCR. This paper describes a colorimetric PCR detection method specific for LT-gene-encoding ETEC strains. DNA was extracted from two representative colonies from each bacterial isolate and amplified by PCR. Digoxigenin was incorporated into the amplification product, permitting a one-step direct detection using anti-digoxigenin alkaline phosphatase-conjugated antibody. This technique was applied to the investigation of 70 E. coli isolates derived from clinical fecal samples obtained from an Irish population. Eleven percent of the samples were LT positive, confirming the applicability of this method. All LT-positive ETEC strains (controls and clinical isolates) were detected, and no false-positive results occurred.

Bacterial translocation during peroperative colonic lavage of the obstructed rat colon.

Peroperative antegrade colonic lavage is often performed before primary anastomosis in emergency colonic surgery. The influence of colonic lavage on bacterial translocation from the obstructed colon was determined. Forty female Wistar rats were studied in four groups: (1) control; (2) non-obstructed with lavage; (3) obstructed; and (4) obstructed with lavage. Ligature obstruction of the rectum was performed in groups 3 and 4. Some 4 days later 35S-radiolabelled Escherichia coli was inoculated into the colon of all animals. Groups 2 and 4 underwent colonic lavage. Lavage in the group 4 animals with left-sided colonic obstruction significantly increased the levels of E. coli in regional nodes, liver, spleen, lung, kidney and blood (as assessed by organ culture and scintillation counting) compared with those in groups 1, 2 and 3 (P < 0.05). These results suggest that peroperative lavage of the obstructed colon significantly increases the level of bacterial translocation.

What is a clinical fact?

As a preliminary to the question, 'What is a clinical fact?', the author asks the wider question, 'What is a fact?', answering that facts are double in aspect: they both say how the world is, and they also depend on our species, our language, theory, etc. A claim of fact in any empirical discipline--in the natural sciences or in human studies with their different methods--is a truth claim which is not infallible or unique to the fact, and also a claim that must offer itself for verification. Using the clinical record of three sessions, she then tries to answer the question, 'What is a clinical fact?', offering the starting formulation that clinical facts, under the unusual conditions of an analytic hour which give an analyst access to a patient's inner world, manifests themselves in the form of immediate psychological realities between patient and analyst. On the way, the author discusses the analyst's anxieties about making a claim of clinical fact; further striking features emerge about clinical facts in the three sessions, and some unsolved problems, i.e. the variety of analytic theories, subjectivity and objectivity, are noted. Even while they bear the perplexities of their problems, clinical facts are of great significance to the study of the mind. They extend the domain of psychology to the area of the mind's interiority, with its human experiences of subjective meaning, conscious, and especially unconscious.

Enclaves and excursions.

This paper describes and names as 'enclaves' and 'excursions' two deteriorations of the psychoanalytic situation, which occur when an analyst exceeds the limited, partial acting out inevitable in clinical work. Under pressure from his patient an analyst may unwittingly turn the analysis into a refuge from disturbance, i.e. an enclave. If he succumbs to pressures to move away from, instead of towards, knowing what is psychically urgent, an analyst may turn the analysis into a series of flights, i.e. an excursion. Unrecognized, these deformations interfere with or even halt the therapeutic process, which requires that the analyst find a way of working which accommodates both the patient's communication of, and need for, a refuge or flight with the analyst, while at the same time analysing it.

Can a liar be psychoanalysed?

At first glance a liar is an inauspicious patient for a psychoanalysis, a treatment based on truthfulness. Because it presents in speech, lying may seem a mature difficulty, but analysis reveals that it is primitive, linked to the habitual liar's doubts and anxieties about communication with primary objects which, from several causes, have become for him lying objects. As expected, lying makes for a series of problems which handicap the analytic process. Even so, the paper illustrates clinically the view that if the fundamental level of the lying that emerges in the analysis is addressed by understanding it as the liar's communication that he is a liar in identification with, and acutely anxious about, his lying object--in the transference the analyst--a genuine analytic process can be set in train.

Carbon dioxide cystometry and postural changes in patients with multiple sclerosis.

Ninety-one subjects with multiple sclerosis were evaluated by carbon dioxide cystometry in the supine, sitting, and standing positions, and by water cystometry in the supine position. Detrusor responses in supine studies were characterized as normal, hyperreflexic, or areflexic. Carbon dioxide and water cystometry were without difference in determining types of detrusor responses. Positional changes (particularly standing) resulted in reassessing of normal supine bladder responses as hyperreflexic. Hyperreflexia was aggravated with sitting and standing. Positional changes did not demonstrate conversion of areflexia to hyperreflexia. The relatively small proportion of dyssynergic sphincter responses probably represents a population of patients with early stage multiple sclerosis. Carbon dioxide cystometry, with positional changes, is relatively safe, easily performed, and an accurate method of evaluating detrusor response in patients with multiple sclerosis who have a changing clinical course or unresponsiveness to treatment.

Urodynamic evaluation of voluntary detrusor response in healthy subjects.

The ability of healthy subjects to voluntarily inhibit a bladder detrusor contraction was evaluated using standard urodynamic techniques. Ten healthy subjects (five men and five women) were appraised using trichannel techniques which included measuring bladder volume, bladder pressure, intraabdominal pressure, and electromyographic activity of the anal or external urethral sphincter. Each subject was first evaluated to determine normalcy of urine flow rate. All subjects were assessed in three positions: supine, sitting, and standing. All ten subjects were able to inhibit their detrusor responses without increasing external urethral or anal sphincter activity or raising the tonus pressure limb of the bladder. Three of the subjects were unable to void during any part of the urodynamic evaluation. In one subject, voiding was accomplished by Valsalva maneuver which mimicked detrusor contraction. At least two subjects did not demonstrate their first urge to void until 300 to 400 cc, and one of these individuals was unable to void until his bladder capacity reached 600cc. These results indicated that normal subjects can inhibit their detrusor response during urodynamic studies. Inability to inhibit this response would therefore appear to be an abnormal pattern. Conversely, inability to produce a detrusor response cannot be called an abnormal retention pattern. Bladder volumes in healthy subjects may be higher than the traditional norms, and this must be taken into account during urodynamic evaluations.
