Abstract
INTRODUCTION The risk of mortality in people with a history of injection drug use (PHID) is high, as is the prevalence of hepatitis C virus (HCV) infection. Although direct-acting antivirals (DAA) are effective in this population in terms of sustained virological response, it is not known whether PHID benefit as much as people with no history of injection drug use from DAA-related HCV cure in terms of reduced all-cause mortality. METHODS Using Cox proportional hazards models based on the ANRS CO22 Hepather cohort data (n = 9735), we identified factors associated with all-cause mortality among HCV-infected people. We tested for interaction effects between drug injection status, HCV cure and other explanatory variables. RESULTS DAA-related HCV cure was associated with a 66% (adjusted hazard ratio [95% confidence interval]: 0.34 [0.29-0.39]) lower risk of all-cause mortality, irrespective of drug injection status. Detrimental effects of unhealthy alcohol use on mortality were identified in PHID only. DISCUSSION AND CONCLUSIONS DAA-related HCV cure led to comparable benefits in terms of reduced mortality in PHID and people with no history of injection drug use. Policies and strategies to enhance DAA uptake among PHID are needed to lower mortality in this population. Clinical trial registration details: ClinicalTrials.gov: NCT01953458.

Abstract
The validity of algorithms for identifying patients with chronic hepatitis B or C virus (HBV or HCV) infection in claims databases has been little explored. The performance of 15 algorithms was evaluated. Data from HBV- or HCV-infected patients enrolled between August 2012 and December 2015 in French hepatology centres (ANRS CO22 HEPATHER cohort) were individually linked to the French national health insurance system (SNDS). The SNDS covers 99% of the French population and contains healthcare reimbursement data. Performance metrics were calculated by comparing the viral status established by clinicians with those obtained with the algorithms identifying chronic HBV- and HCV-infected patients. A total of 14 751 patients (29% with chronic HBV and 63% with chronic HCV infection) followed-up until December 2018 were selected. Despite good specificity, the algorithms relying on ICD-10 codes performed poorly. By contrast, the multi-criteria algorithms combining ICD-10 codes, antiviral dispensing, laboratory diagnostic tests (HBV DNA or HCV RNA detection and quantification, HCV genotyping), examinations for the assessment of liver fibrosis and long-term disease registrations were the most effective (sensitivity 0.92, 95% CI, 0.91-0.93 and specificity 0.96, 95% CI, 0.95-0.96 for identifying chronic HBV-infected patients; sensitivity 0.94, 95% CI, 0.94-0.94 and specificity 0.85, 95% CI, 0.84-0.86 for identifying chronic HCV-infected patients). In conclusion, the multi-criteria algorithms perform well in identifying patients with chronic hepatitis B or C infection and can be used to estimate the magnitude of the public health burden associated with hepatitis B and C in France.

Abstract
Background Patients with chronic hepatitis C virus (HCV) infection are at greater risk of developing metabolic disorders. Obesity is a major risk factor for these disorders, and therefore, managing body weight is crucial. Cannabis use, which is common in these patients, has been associated with lower corpulence in various populations. However, this relationship has not yet been studied in persons with chronic HCV infection. Methods Using baseline data from the French ANRS CO22 Hepather cohort, we used binary logistic and multinomial logistic regression models to test for an inverse relationship between cannabis use (former/current) and (i) central obesity (i.e., large waist circumference) and (ii) overweight and obesity (i.e., elevated body mass index (BMI)) in patients from the cohort who had chronic HCV infection. We also tested for relationships between cannabis use and both waist circumference and BMI as continuous variables, using linear regression models. Results Among the 6348 participants in the study population, 55% had central obesity, 13.7% had obesity according to their BMI, and 12.4% were current cannabis users. After multivariable adjustment, current cannabis use was associated with lower risk of central obesity (adjusted odds ratio, aOR [95% confidence interval, CI]: 0.45 [0.37–0.55]), BMI-based obesity (adjusted relative risk ratio (aRRR) [95% CI]: 0.27 [0.19–0.39]), and overweight (aRRR [95% CI]: 0.47 [0.38–0.59]). This was also true for former use, but to a lesser extent. Former and current cannabis use were inversely associated with waist circumference and BMI. Conclusions We found that former and, to a greater extent, current cannabis use were consistently associated with smaller waist circumference, lower BMI, and lower risks of overweight, obesity, and central obesity in patients with chronic HCV infection. Longitudinal studies are needed to confirm these relationships and to assess the effect of cannabis use on corpulence and liver outcomes after HCV cure.

Abstract
Assessment of the intensity, dynamics and determinants of the antibody response after SARS-CoV-2 infection or vaccination in the general population is critical to guide vaccination policies. This study characterized the anti-spike IgG titers in 13,971 participants included in a French multicohort population-based serological survey on COVID-19 between April and October 2020 and followed-up with serological testing between May and October 2021. Eight follow-up profiles were defined depending on SARS-CoV-2 infection (0, 1 or 2) and COVID-19 vaccination (0, 1, 2 or 3). The anti-spike titer was lower in adults with no vaccination even in case of infection or reinfection, while it was higher in adults with infection followed by vaccination. The anti-spike titer was negatively correlated with age in vaccinated but uninfected adults, whereas it was positively correlated with age in unvaccinated but infected adults. In adults with 2 vaccine injections and no infection, the vaccine protocol, age, gender, and time since the last vaccine injection were independently associated with the anti-spike titer. The decrease in anti-spike titer was much more rapid in vaccinated than in infected subjects. These results highlight the strong heterogeneity of the antibody response against SARS-CoV-2 in the general population depending on previous infection and vaccination.

Abstract
Background & Aims After HCV cure, not all patients achieve significant liver fibrosis regression. We explored the effects of clinical and socio-behavioral factors on liver fibrosis, before and after HCV cure with direct-acting antivirals. Methods We analyzed data from the ongoing ANRS CO22 HEPATHER cohort, which prospectively collects clinical and socio-behavioral data on HCV-infected patients. Mixed-effects logistic regression models helped identify predictors of longitudinal measures of severe liver fibrosis, defined as a fibrosis-4 index >3.25. We also estimated the adjusted population attributable fractions (PAFs) for modifiable risk factors. Results Among the 9,692 study patients (accounting for 24,687 visits over 4 years of follow-up, 48.5% of which were post-HCV cure), 26% had severe fibrosis at enrolment. After multivariable adjustment, HCV-cured patients had an 87% lower risk of severe fibrosis. An inverse dose-response relationship was found for coffee consumption, with the risk of severe fibrosis diminishing by 58% per additional cup/day (adjusted odds ratio (aOR 0.42; 95% CI 0.38-0.46). Unemployment, low educational level, and diabetes were associated with a higher severe fibrosis risk (aOR 1.69; 95% CI 1.32-2.16, aOR 1.50; 95% CI 1.20-1.86, and aOR 4.27; 95% CI 3.15-5.77, respectively). Severe fibrosis risk was 3.6/4.6-fold higher in individuals with previous/current unhealthy alcohol use than in abstinent patients. All these associations remained valid after HCV cure. The risk factors accounting for the greatest severe fibrosis burden were unemployment, low education level, and diabetes (PAFs: 29%, 21%, and 17%, respectively). Conclusions Monitoring liver fibrosis after HCV cure is crucial for patients with low socioeconomic status, previous/current unhealthy alcohol use, and diabetes. Innovative HCV care models for the most socially vulnerable individuals and interventions for healthier lifestyles are needed to reinforce the positive effects of HCV cure on liver health. Lay summary After hepatitis C virus (HCV) cure, not all patients achieve significant liver fibrosis regression. Herein, we studied the effects of clinical and socio-behavioral factors on the risk of severe liver fibrosis. Coffee consumption was strongly inversely associated with severe fibrosis, while diabetes, previous and current unhealthy alcohol use were associated with a 4.3-, 3.6- and 4.6-fold higher risk of severe fibrosis, respectively. Unemployment and low educational level were also associated with a higher risk of severe fibrosis. All these associations remained valid after HCV cure. These results demonstrate the need to continue liver fibrosis monitoring in at-risk groups, and to facilitate healthier lifestyles after HCV cure as a clinical and public health priority. Liver fibrosis assessment is a key prognostic tool in the hepatitis C cure era. Significant liver fibrosis regression does not always occur after hepatitis C cure. Coffee intake displays protective effects on severe fibrosis even after HCV cure. Social vulnerability, diabetes, and unhealthy alcohol use predict severe fibrosis. Socio-behavioral factors are associated with severe fibrosis even after HCV cure.

Abstract
BACKGROUND We aimed to estimate the seropositivity to anti-SARS-CoV-2 antibodies in May-June 2020 after the first lockdown period in adults living in three regions in France and to identify the associated risk factors. METHODS Between 4 May 2020 and 23 June 2020, 16 000 participants in a survey on COVID-19 from an existing consortium of three general adult population cohorts living in the Ile-de-France (IDF) or Grand Est (GE) (two regions with high rate of COVID-19) or in the Nouvelle-Aquitaine (NA) (with a low rate) were randomly selected to take a dried-blood spot for anti-SARS-CoV-2 antibodies assessment with three different serological methods (ClinicalTrial Identifier #NCT04392388). The primary outcome was a positive anti-SARS-CoV-2 ELISA IgG result against the spike protein of the virus (ELISA-S). Estimates were adjusted using sampling weights and post-stratification methods. Multiple imputation was used to infer the cumulative incidence of SARS-CoV-2 infection with adjustments for imperfect tests accuracies. RESULTS The analysis included 14 628 participants, 983 with a positive ELISA-S. The weighted estimates of seropositivity and cumulative incidence were 10.0% [95% confidence interval (CI): 9.1%, 10.9%] and 11.4% (95% CI: 10.1%, 12.8%) in IDF, 9.0% (95% CI: 7.7%, 10.2%) and 9.8% (95% CI: 8.1%, 11.8%) in GE and 3.1% (95% CI: 2.4%, 3.7%) and 2.9% (95% CI: 2.1%, 3.8%) in NA, respectively. Seropositivity was higher in younger participants [odds ratio (OR) = 1.84 (95% CI: 1.79, 6.09) in <40 vs 50-60 years old and OR = 0.56 (95% CI: 0.42, 0.74) in ≥70 vs 50-60 years old)] and when at least one child or adolescent lived in the same household [OR = 1.30 (95% CI: 1.11, 1.53)] and was lower in smokers compared with non-smokers [OR = 0.71 (95% CI: 0.57, 0.89)]. CONCLUSIONS Seropositivity to anti-SARS-CoV-2 antibodies in the French adult population was ≤10% after the first wave. Modifiable and non-modifiable risk factors were identified.

Abstract
The presence of specific antibodies against human polyomavirus 12, Saint Louis polyomavirus and New Jersey polyomavirus was investigated by using virus-like particle-based ELISAs with serum samples from 706 Italians aged 1- to 100-years-old. The findings indicate that these polyomaviruses circulate widely in humans, with peak seroprevalence, observed at adulthood, of 97.3%, 93.3%, 57.5%, for human polyomavirus 12, Saint Louis polyomavirus and New Jersey polyomavirus, respectively.

Abstract
REASONS FOR PERFORMING STUDY The bronchoalveolar lavage (BAL) procedure can return variable volumes of fluid, possibly depending on the presence of bronchial collapse during fluid aspiration and on the severity of lung inflammation. OBJECTIVES We tested the hypothesis that horses with bronchial collapse during BAL are at higher risk of having severe lung inflammation. STUDY DESIGN Prospective field study. METHODS Bronchial collapse was graded using a new simple scoring method (0, 1 or 2) during a standardised BAL procedure in the field on 131 horses with normal, mild/moderate or severe lower airway inflammation on cytology of BAL fluid. RESULTS Of the 131 horses, 37 (28%), 55 (42%) and 39 (30%) horses had bronchial collapse scores of 0, 1 and 2, respectively. There was a difference in collapse scores between all the BAL inflammation categories (P<0.001). Severe collapse had a positive predictive value of 0.95 for both mild/moderate and severe BAL inflammation, with a prevalence of 63% and 20%, respectively. The BAL fluid return volume in the horses with severe collapse scores was lower than volumes in the partial (score 1/2) and no collapse (score 0/2) groups (P<0.001). The BAL fluid volume was negatively correlated with BAL neutrophil percentage (P<0.001). CONCLUSIONS Airway collapse during BAL is associated with airway inflammation and neutrophilia. POTENTIAL RELEVANCE During a standardised BAL procedure, clinicians can expect lung inflammation in horses that have bronchial collapse and bronchial collapse in horses with lung inflammation. Lung inflammation may be a contributing factor in the mechanism of bronchial collapse during BAL in horses.

Abstract
REASONS FOR PERFORMING STUDY The diagnosis of equine recurrent airway obstruction (RAO) and inflammatory airway disease (IAD) is based on clinical signs and increased inflammatory cell percentages in the bronchoalveolar lavage (BAL) fluid. Since a BAL is an invasive procedure, a risk-screening questionnaire (RSQ) would be a valuable screening tool for lung inflammation. OBJECTIVE To evaluate the accuracy of a RSQ to detect lower airway inflammation (LAI) in a large population of horses. METHODS A standardised BAL was performed in the field on 167 horses in Alberta, Canada. Horses were separated into 3 categories: 1) BAL normal; 2) BAL mild to moderate LAI (MLAI), and 3) BAL severe LAI (SLAI). The horse owners were asked to complete a RSQ. The RSQ scores were compared to the BAL results to determine the likelihood of a horse having MLAI, SLAI or no LAI. RESULTS Based on BAL cytology, 28 (17%) horses were normal and 139 (83%) were abnormal, with 110 (66%) showing MLAI and 29 (17%) SLAI. Horses with SLAI and MLAI had a mean RSQ score of 0.95 and 0.70, respectively, compared to 0.60 for normal BAL horses. Horses with SLAI showed more clinical signs than normal and MLAI horses. The sensitivity and negative predictive values of the RSQ for detecting SLAI using a cut-off score of 0.87, were excellent at 0.90 (95%CI 0.73-0.98) and 0.96 (95%CI 0.82-1.00). Questions on the clinical signs typically found in RAO cases differed significantly between horses with BAL SLAI and those with BAL normal. CONCLUSIONS Prevalence of MLAI was high in this population. Although the RSQ did not allow differentiating normal horses from horses with MLAI, it has a high sensitivity to detect horses with SLAI and is therefore a good screening tool for SLAI.

Abstract
OBJECTIVES To determine whether acute exercise associated muscle cramping (EAMC) in distance runners is related to changes in serum electrolyte concentrations and hydration status. METHODS A cohort of 72 runners participating in an ultra-distance road race was followed up for the development of EAMC. All subjects were weighed before and immediately after the race. Blood samples were taken before the race, immediately after the race, and 60 minutes after the race. Blood samples were analysed for glucose, protein, sodium, potassium, calcium, and magnesium concentrations, as well as serum osmolality, haemoglobin, and packed cell volume. Runners who suffered from acute EAMC during the race formed the cramp group (cramp, n = 21), while runners with no history of EAMC during the race formed the control group (control, n = 22). RESULTS There were no significant differences between the two groups for pre-race or post-race body weight, per cent change in body weight, blood volume, plasma volume, or red cell volume. The immediate post-race serum sodium concentration was significantly lower (p = 0.004) in the cramp group (mean (SD), 139.8 (3.1) mmol/l) than in the control group (142.3 (2.1) mmol/l). The immediate post-race serum magnesium concentration was significantly higher (p = 0.03) in the cramp group (0.73 (0.06) mmol/l) than in the control group (0.67 (0.08) mmol/l). CONCLUSIONS There are no clinically significant alterations in serum electrolyte concentrations and there is no alteration in hydration status in runners with EAMC participating in an ultra-distance race.

Abstract
Scorpions are fluorogenic PCR primers with a probe element attached at the 5'-end via a PCR stopper. They are used in real-time amplicon-specific detection of PCR products in homogeneous solution. Two different formats are possible, the 'stem-loop' format and the 'duplex' format. In both cases the probing mechanism is intramolecular. We have shown that duplex Scorpions are efficient probes in real-time PCR. They give a greater fluorescent signal than stem-loop Scorpions due to the vastly increased separation between fluorophore and quencher in the active form. We have demonstrated their use in allelic discrimination at the W1282X locus of the ABCC7 gene and shown that they can be used in assays where fluorescence resonance energy transfer is required.

Abstract
This paper examines the role of semantic factors in the production of subject-verb number agreement. As an ostensibly grammatical process, number agreement provides an interesting case for examining the flow and interaction of semantic and syntactic information through the language-production system. Using a sentence-completion task, agreement errors can be elicited from subjects by presenting them with sentence fragments containing a complex noun-phrase, in which the nonhead noun is plural (e.g., The key to the cabinets ... WERE missing.). Previous research has demonstrated that the probability of making an error can be affected by varying the properties of the nouns in the complex noun phrase. By investigating which variables do and do not affect error rates, constraints on the flow of information through the production system can be inferred. In three experiments, we investigated the possible effects of three different semantic manipulations of the nouns in the complex NP: animacy, semantic overlap, and plausibility of modification by the sentence predicate. We found that both animacy and semantic relatedness had reliable effects on error rates, indicating that the mechanism involved in implementing agreement cannot be blind to semantic information. However, the plausibility with which each noun could serve as the subject of the sentence predicate had no effect on error rates. Taken together, these results suggest that while semantic information is visible to the agreement mechanism, there are still constraints on when this information can affect the process. Specifically, it may be the case that only information contained within the complex NP is considered for the purposes of implementing agreement.

Abstract
This paper examines the role of word frequency in the computation of subject-verb number agreement. Previous research in both production and comprehension has demonstrated that processing difficulties can arise in sentence structures containing a singular subject noun followed by a plural "distractor" noun, as in The key to the cabinets.... A whole sentence reading task was employed to determine whether the relative frequency with which the distractor noun appears in its singular or plural form would affect the degree of processing difficulty experienced by readers. Results suggest that the agreement process is, indeed, sensitive to this factor and this finding is compatible with activation-based accounts of the implementation of number agreement.

Abstract
In this paper we address the question whether hierarchical relations and word order can be separated in sentence production. In two experiments, we assess whether subject-verb agreement errors (such as 'The time for fun and games are over') require linear proximity of a so-called 'local' noun ('games' in the example) to the verb. In the first experiment, we found a proximity effect when participants were asked to complete sentential beginnings of the kind: 'The helicopter for the flights'. In the second experiment, we asked participants to produce a question such as 'Is the helicopter for the flights safe?'. The syntactic relation between the subject noun and the local noun is the same in the two experiments, but the linear position of the local noun is different. The distribution of agreement errors was similar in the two experiments. We argue that these data provide evidence for a stage in language production in which a syntactic structure is built prior to a stage in which words are assigned to their linear position. Agreement is computed during the first stage.

Abstract
This study analysed medical record data from seven regional hospitals in Queensland to determine the types of medical conditions and injuries that resulted in overseas and interstate tourists being admitted to hospital. From a total of 135,128 admissions to the participating hospitals, 695 (0.51 per cent) were identified as overseas tourists and 3479 (2.57 per cent) were from interstate. The main reasons for admission of overseas tourists, based on principal diagnoses, were injuries and poisonings (37.6 per cent), circulatory disorders (11.7 per cent), digestive conditions (9.8 per cent), and genito-urinary disorders (8.8 per cent). For interstate tourists, the main reasons for admission were genito-urinary disorders (19.8 per cent), injuries and poisonings (15.4 percent), neoplasms (11.4 per cent) and circulatory disorders (10.6 per cent). These findings are discussed in relation to current literature in the field of travel medicine, emphasising the burden of care placed on the admitting hospital's resources, and the growing number of visitors to Queensland needing health care.

Abstract
The ICD-10 is due to be introduced into Australia during the late 1990s, superseding the current and widely used ICD-9-CM. Improvements in areas such as number of codes, an expanded external cause framework, and more context to injuries are expected to make the ICD-10 a more streamlined system for practitioners. The present study examined both classification formats using data from 1183 presentations to primary health clinics at island tourist resorts. Some initial observations are made about differences in the two systems, highlighting the greater coding detail provided by the ICD-10, particularly in the area of injuries. It is recommended that further empirical testing be undertaken using the ICD-10 in a variety of settings so as to identify benefits in the coding of both medical conditions and injuries.

Abstract
To evaluate the clinical impact of prolonged parenteral nutritional (PN) therapy on patients with advanced cystic fibrosis, we conducted a retrospective chart review of 25 cystic fibrosis patients who underwent prolonged PN (median course 295 days) at our institution between August 1988 and May 1992. The patients' survival status, change in percentage of ideal body weight, need for ongoing nutritional intervention, pulmonary function test changes, i.v. antibiotic use, and complication rates were assessed. Patients gained significant weight while receiving PN, but they lost weight when PN was discontinued. PN did not clearly improve pulmonary status. IV antibiotic therapy nearly doubled during PN. Central venous catheter sepsis rates rose from 1.29 to 3.45 per 1000 catheter days during PN therapy. In conclusion, prolonged PN promotes weight gain in cystic fibrosis patients with severe disease; however, the effect is transient and involves a significantly increased risk of sepsis.

Abstract
In response to concerns about the number of interstate and overseas visitors using Queensland hospital services, the present study examined a sample of 1,295 hospital records to determine the proportion of patients who were incorrectly identified as Queensland residents. Across six hospitals the overall detection rate was 4.6%. Rates varied between hospitals, with the highest detection recorded for Goondiwindi near the Queensland/New South Wales border; and the lowest for Prince Charles in Brisbane. There were also important variations across hospitals based on specific holiday periods. In particular, Goondiwindi and the Gold Coast had substantially higher detection rates for the Christmas holiday period (December-January) than for the mid-year period (June-August). These findings are discussed in terms of their implications for hospital services, especially lost revenue and increased patient load. Health information managers are identified as a key group for addressing some of the current problems in this area.

Abstract
A model that makes use of the cooperative organization of inorganic and organic molecular species into three dimensionally structured arrays is generalized for the synthesis of nanocomposite materials. In this model, the properties and structure of a system are determined by dynamic interplay among ion-pair inorganic and organic species, so that different phases can be readily obtained through small variations of controllable synthesis parameters, including mixture composition and temperature. Nucleation, growth, and phase transitions may be directed by the charge density, coordination, and steric requirements of the inorganic and organic species at the interface and not necessarily by a preformed structure. A specific example is presented in which organic molecules in the presence of multiply charged silicate oligomers self-assemble into silicatropic liquid crystals. The organization of these silicate-surfactant mesophases is investigated with and without interfacial silicate condensation to separate the effects of self-assembly from the kinetics of silicate polymerization.

Abstract
An unfamiliar holiday environment may give rise to a range of common and unique medical conditions and injuries. Based on a six-month retrospective analysis of clinic records, the present study reports a detailed profile of health services provided for guests at three tropical island tourist resorts. A total of 1183 clinic visits were analysed; 735 (62 per cent) concerned medical conditions, while 448 (38 per cent) were related to injuries. The most common medical conditions treated were respiratory, digestive, skin problems, eye disorders, and genito-urinary complaints. Injuries included lacerations, bites and stings, sprains and fractures. Health services consisted mainly of medication, specialist nursing care and first aid. Study findings highlight the advantages of using an internationally accepted classification system for primary health research, and the critical role of the nurse in tourist health services.

Abstract
Thirteen right-handed adult speakers, including five patients with unilateral left-hemisphere damage, four patients with unilateral right-hemisphere damage, and four patients with non-neurological damage, read aloud sentences designed to test influences of clause and utterance length on two acoustical measures of intonation, fundamental voice frequency ( Fo) and timing. Patients with unilateral damage to the left-hemisphere exhibited more abnormality in Fo and speech timing than did patients with right-hemisphere damage.

Abstract
A cost-effective pulmonary rehabilitation program can be created by using strategic planning, a thorough budgetary process, and then promotion of the program. Strategic planning assesses the need for such a program, develops its overall direction, establishes priorities, assesses economic factors and the presence or absence of similar services already in existence, and identifies the proposed scope of the program. The budgetary process identifies the specific services to be offered and estimates the volume of services, their costs, and revenues. Promotion of the program serves to acquaint potential referring physicians and patients with the services to be offered. If preliminary investigation indicates that a pulmonary rehabilitation program is needed in the community, then strategic planning, careful budgeting, and creative promotion can help assure that the program is financially viable.

Abstract
Questionnaires were sent out to 68 registered female veterinary surgeons in South Africa to obtain career information essential to vocational guidance. The 46 respondents represent 51,7% of the 89 female BVSc graduates up to 1981; their average age was 33,3 years, 63% were married, 30,4% were from the Pretoria area, 60,9% were living in the Transvaal, 52,2% had had 6 and more years of veterinary experience. All the comparisons done indicated that the response group was representative of the women who had obtained the BVSc degree from the University of Pretoria. Some of the more important findings were the following: No less than 97,8% of the response group are at present actively engaged in veterinary work--73,9% on a full-time basis. Asked what they would choose now, 84,8% of the respondents declared that they would choose veterinary science once again; 67,4% would like to see their daughters enter the profession. The most important reason for this positive attraction towards veterinary practice was given as "job satisfaction experienced". Respondents indicated the things that they liked about veterinary practice: factors intrinsic to the job like surgery, pathology and research topped the list followed by the opportunity to work with and help animals and also the variety experienced in their work. The most important grievances were firstly the general attitude and actions of the public--callousness of animal-owners and inconsiderate behaviour towards practitioners. Long and irregular hours, administrative red tape and insufficient technical help were also complaints.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The usefulness of the various tests of thyroid function has been evaluated over a three-year period. It is concluded that an uptake test and estimation of the serum protein-bound radioactive iodine (PB (131)I), supplemented as required by the protein-bound iodine (PBI), remain the best routine tests of thyroid function. Forty-five patients who gave discordant results on these tests over this period have been studied in detail and the value of other tests of thyroid function has been explored.
