Abstract
Amyloid light chain (AL) amyloidosis is a rare and chronic bone marrow disorder. Existing claims data can be used to help understand the real-world treatment patterns and outcomes of this patient population. Various population-based administrative databases in Alberta, Canada were queried from 2010 to mid-2019 to identify cases of AL amyloidosis. Baseline patient and disease characteristics, sequencing of pharmacologic therapies, overall survival, and healthcare resource utilization were evaluated. A total of 215 individuals with AL amyloidosis were included. Among patients diagnosed between 2012 and 2019, 149 (85.1%) initiated first-line, 67 (38.3%) initiated second-line, 22 (12.6%) initiated third-line, and 11 (6.3%) initiated fourth-line systemic therapy. In the first-line setting, 99/149 (66.4%) received bortezomib, cyclophosphamide, and dexamethasone (CyBorD) and 21/149 (14.1%) received another bortezomib-based regimen. Survival from time of diagnosis improved over time, with a median overall survival of 25.8 months (95% CI: 9.8, 57.1) for individuals diagnosed in 2010-2011 versus 52.1 months (95% CI: 25.6, NA) for those diagnosed in 2012-2019. Despite this improvement, the proportion of individuals diagnosed in 2012-2019 who survived beyond five-years remained low (5-year survival: 48.4%; 95% CI: 40.9, 57.2) which highlights an unmet need for more efficacious therapies.

Abstract
INTRODUCTION Abiraterone acetate plus prednisone (AA+P) has shown to significantly improve survival. COSMiC, a Canadian Observational Study in Metastatic Cancer of the Prostate, set out to prospectively amass real-world data on metastatic castration-resistant prostate cancer (mCRPC) patients managed with AA+P in Canada. Herein, we report their patient-reported outcomes (PROs). METHODS After a median followup of 67.1 weeks, 254 patients were enrolled across 39 sites. Functional Assessment of Cancer Therapy-Prostate (FACT-P), Montreal Cognitive Assessment (MoCA), Brief Pain Inventory-Short Form (BPI-SF), Brief Fatigue Inventory (BFI), and Current Health Satisfaction in Prostate Cancer (CHS-PCa) were evaluated at baseline, as well as at weeks 12, 24, 48, and 72 after AA+P initiation. Descriptive analysis was used with continuous variables. Changes from baseline were summarized using mean (standard deviation [SD]). RESULTS At a median age of 76.6 (8.94), baseline FACT-P total score was 111.3 (19.56) with no significant change in their functional status observed from baseline over time. The median baseline MoCA score was 25.2 (4.52), yet subsequent assessments showed an absence of cognitive decline while under treatment. Similarly, no meaningful changes were detected in BPI, BFI, and CHS-PCa during the 72-week study period, thus suggesting that patients' PROs were well-maintained throughout AA+P treatment. Prostate-specific antigen (PSA) response with >50% decline was 66.4%. Safety profile was consistent with the known side effect of AA+P. CONCLUSIONS COSMiC represents the largest Canadian mCRPC cohort treated with AA+P with real-world, prospective evaluation of PROs. This data demonstrated the maintenance in quality of life and cognitive status over the course of the study and underscores the importance of PRO use in this complex patient population.

Abstract
Abstract
The VIDAS SLM method for detection of Salmonella was compared with the Bacteriological Analytical Manual (BAM)/AOAC culture method in a collaborative study. Twenty laboratories participated in the evaluation. Each laboratory tested one or more of 6 test products: milk chocolate, nonfat dry milk, dried whole egg, soy flour, ground black pepper, and ground raw turkey. No significant differences (P< 0.05) were observed between the 2 methods. The 2 methods were in agreement for 99% of 1544 samples analyzed. Of the 20 samples out of agreement, 8 were VIDAS SLM positive and BAM/AOAC negative, and 12 were VIDAS SLM negative and BAM/AOAC positive. The VIDAS SLM method for detection of Salmonella in foods has been adopted first action by AOAC INTERNATIONAL.

Abstract
Pathogens and fecal indicator bacteria occurrence and removal were studied for a period of 6 months at the Montreal Urban Community wastewater treatment facility. With a capacity of about 7.6 million cubic metres per day (two billion U.S. gallons per day), it is the largest primary physico-chemical treatment plant in America. The plant discharges a nondisinfected effluent containing about 20 mg/L of suspended matter and 0.5 mg/L of total phosphorus on the basis of average annual concentrations. BDO5 (annual mean) is 75 mg/L before treatment and 32 mg/L after treatment. Samples were collected for a period of 6 months, and they demonstrated that the plant was not efficient at removing indicator bacteria and the pathogens tested. Fecal coliforms were the most numerous of the indicator bacteria and their removal averaged 25%. Fecal streptococci removal was 29%, while Escherichia coli removal was 12%. In untreated sewage, fecal coliforms, E. coli, and human enteric viruses were more numerous in summer and early autumn. Fecal streptococci counts remained relatively similar throughout the period. Clostridium perfringens removal averaged 51%. Giardia cysts levels were not markedly different throughout the study period, and 76% of the cysts were removed by treatment. Cryptosporidium oocyst counts were erratic, probably due to the methods, and removal was 27%. Human enteric viruses were detected in all samples of raw and treated wastewater with no removal observed (0%). Overall, the plant did not perform well for the removal of fecal indicator bacteria, human enteric viruses, or parasite cysts. Supplementary treatment and disinfection were recommended to protect public health. Various alternatives are being evaluated.

Abstract
Quebec and Denmark passed legislation in 1981 that aims to protect pregnant women and their unborn children from health hazards in the workplace. Finland passed similar legislation in 1991. While these measures have much in common, they are applied in very different ways. Approximately 1% of pregnant working women benefit from a "special maternity leave" in Denmark, compared with 0.1% in Finland, while in Quebec, nearly 40% of working women benefit from preventive reassignment measures during their pregnancies. In this article, we will analyze the reasons for these disparities between rates of utilization in Finland, Denmark, and Quebec in light of the Quebec experience over the last 16 years.

Abstract
A series of novel monobactam inhibitors of human cytomegalovirus (HCMV) protease has been described that possess a heterocyclic thiomethyl side chain at C-4. Changes to the heterocycle did not significantly change the inhibitory activity of these compounds in an enzymatic assay, although improvements in solubility and cell culture activity were noted. A number of permutations between C-4 substitutions and N-1 derivatives led to the identification of several beta-lactams with antiviral activity in a plaque reduction assay. N-methyl thiotetrazole-containing compounds were found to be the most potent inhibitors in the enzymatic assay.

Abstract
The development of novel monobactam inhibitors of HCMV protease incorporating a carbon side chain at C-4 and a urea function at N-1 is described. Substitution with small groups at the C-3 position of the beta-lactam ring gave an increase in enzymatic activity and in stability; however, a lack of selectivity against other serine proteases was noted. The use of both tri- and tetrasubstituted urea functionalities gave effective inhibitors of HCMV protease. Benzyl substitution of the urea moiety was beneficial, especially when strong electron-withdrawing groups where attached at the para position. Modest antiviral activity was found in a plaque reduction assay.

Abstract
The development of peptidomimetic inhibitors of the human cytomegalovirus (HCMV) protease showing sub-micromolar potency in an enzymatic assay is described. Selective substitution of the amino acid residues of these inhibitors led to the identification of tripeptide inhibitors showing improvements in inhibitor potency of 27-fold relative to inhibitor 39 based upon the natural tetrapeptide sequence. Small side chains at P1 were well tolerated by this enzyme, a fact consistent with previous observations. The S2 binding pocket of HCMV protease was very permissive, tolerating lipophilic and basic residues. The substitutions tried at P3 indicated that a small increase in inhibitor potency could be realized by the substitution of a tert-leucine residue for valine. Substitutions of the N-terminal capping group did not significantly affect inhibitor potency. Pentafluoroethyl ketones, alpha,alpha-difluoro-beta-keto amides, phosphonates and alpha-keto amides were all effective substitutions for the activated carbonyl component and gave inhibitors which were selective for HCMV protease. A slight increase in potency was observed by lengthening the P1' residue of the alpha-keto amide series of inhibitors. This position also tolerated a variety of groups making this a potential site for future modifications which could modulate the physicochemical properties of these molecules.

Abstract
We have been investigating the potential of a new class of antiviral compounds. These peptidomimetic derivatives prevent association of the two subunits of herpes simplex virus (HSV) ribonucleotide reductase (RR), an enzyme necessary for efficient replication of viral DNA. The compounds disclosed in this paper build on our previously published work. Structure-activity studies reveal beneficial modifications that result in improved antiviral potency in cell culture in a murine ocular model of HSV-induced keratitis. These modifications include a stereochemically defined (2,6-dimethylcyclohexyl)amino N-terminus, two ketomethylene amide bond isosteres, and a (1-ethylneopentyl)amino C-terminus. These three modifications led to the preparation of BILD 1351, our most potent antiherpetic agent containing a ureido N-terminus. Incorporation of the C-terminal modification into our inhibitor series based on a (phenylpropionyl)valine N-terminus provided BILD 1357, a significantly more potent antiviral compound than our previously published best compound, BILD 1263.

Abstract
We have been investigating peptidomimetic inhibitors of herpes simplex virus (HSV) ribonucleotide reductase (RR). These inhibitors bind to the HSV RR large subunit and consequently prevent subunit association and subsequent enzymatic activity. This report introduces a new series of compounds that contain an extra nitrogen (a ureido function) at the inhibitor N-terminus. This nitrogen improves inhibitor binding potency 50-fold over our first published inhibitor series. Evidence supports that this improvement in potency results from a new hydrogen-bonding contact between the inhibitor and the RR large subunit. This report also provides evidence for the bioactive conformation around two important amino acid residues contained in our inhibitors. A tert-butyl group, which contributes 100-fold to inhibitor potency but does not directly bind to the large subunit, favors an extended beta-strand conformation that is prevalent in solution and in the bound state. More significantly, the bioactive conformation around a pyrrolidine-modified asparagine residue, which contributes over 30 000-fold to inhibitor potency, is elucidated through a series of conformationally restricted analogues.

Abstract
We have been investigating a new class of antiviral compounds effective against herpes simplex virus (HSV) in vitro and in vivo. Antiviral activity results from inhibition of HSV ribonucleotide reductase (RR). The inhibitors are designed as mimics of the RR small subunit C-terminus, a region essential for RR subunit association and consequently enzymatic activity. Inhibition results from specific binding of the inhibitor to the HSV RR large subunit thereby preventing subunit association. This report details the structure--activity studies that lead to the indentification of BILD 1263, a potent inhibitor of HSV RR subunit association (IC50, 0.2 nM) that also inhibits the replication of HSV types 1 and 2 in cell culture (EC50, 3 and 4 microM) and reduces the severity of HSV-1-induced keratitis in a murine ocular model. The discovery of inhibitors with in vitro antiviral results from a combination of improving inhibitor potency in a RR binding assay and modifying inhibitor physicochemical properties. The importance and possible role of the new structural modifications introduced into this inhibitor series is discussed.

Abstract
A stent-graft was placed percutaneously in the right renal artery of a 50-year-old woman with hypertension and a fibromuscular dysplastic lesion consisting of severe stenoses and a 1.5-cm saccular aneurysm with a wide neck. At 1-year follow-up with arteriography, arterial luminal diameter was normal and no aneurysm was depicted. The patient's blood pressure was normal without blood pressure medication.

Abstract
As part of a comparative and collaborative study of rapid methods for the detection of Salmonella and the standard Health Protection Branch (HPB) method, six Federal and Provincial Laboratories compared the EF-18 agar/Hydrophobic Grid Membrane Filters (HGMF) method to the standard HPB method. Two Federal Laboratories also compared the enzyme linked antibody (ELA)/HGMF method (which is a further development of the EF-18 agar/HGMF method) to the standard method. During this study the false-negative rates ranged from 0% to 15% for the standard HPB method, from 5.88% to 43.5% for the EF-18 agar/HGMF method, and from 0% to 10.5% for the ELA/HGMF method. The EF-18 agar/HGMF method did not compare well with the standard HPB method due to the number of false-negatives. Problems with this method resulted from the inability to isolate colonies of Salmonella on the HGMF due to the small colony size, abnormal colony coloration, and overgrowth by competitors. The ELA/HGMF method, however, was shown to be comparable to the standard HPB method. The main advantages of this method are that the antibody-staining step is independent of colony coloration and carbohydrate utilization on the plating media; the ability to detect some unusual strains of Salmonella irrespective of their atypical reactions on the media; and the ELA staining can indicate the presence of Salmonella even when the HGMF is overgrown by competitors. Also, cultural confirmation can proceed simultaneously yet independently of the ELA staining procedure. The data presented here indicate that this method is worth further study.

Abstract
Incorporating beta-alkylated aspartic acid derivatives into herpes simplex virus ribonucleotide reductase subunit association inhibitors can improve inhibitor potency up to 50 times over the corresponding inhibitors containing an unsubstituted aspartic acid. A combination of NMR studies, conformational analysis, and molecular mechanics calculations suggests that the beta-alkyl group improves inhibitor potency by favoring the bioactive conformation of the critical aspartic acid carboxyl group. Further support for this hypothesis is provided by a potent conformationally restricted aspartic acid derivative in which the carboxyl group is locked in the putative bioactive conformation.

Abstract
Nineteen laboratories across Canada took part in a comparative study of the 'FDA' and 'USDA' methods for the detection of Listeria monocytogenes in foods and environmental samples. The results show that the enrichment period of the FDA method can be shortened from 7 to 2 days without substantially reducing the number of positive samples. With a limited number of samples, the USDA method proved to be slightly more efficient in isolating L. monocytogenes than the FDA method. Fraser broth, in principle, proved to be useful as a screening tool but is not very selective. Oxford agar and lithium chloride-phenylethanol-moxalactam medium were better than modified McBride's agar in isolating this microorganism.

Abstract
Using data from a cross-sectional survey on 570 fifteen year old students living in non-fluoridated public school sectors on the Island of Montreal in 1987, the effect of terminating the restorative aspect of public dental health care insurance for twelve to fifteen year old students is examined. This study also highlights the level and quality of dental caries treatment on the twelve to fifteen year old group. The main point to be made is that there was an improvement in the DMFT index values of fourteen and fifteen year old students in metropolitan areas. In reality, fourteen year old children had a DMFT index of 6.45 in 1983-1984, while the fifteen year old children in the 06A region (non-fluoridated area) had a DMFT of 6.07 in 1987. Since the metropolitan fluoridated area had been eliminated from the results in 1987, it is quite obvious that the 6.07 result obtained overestimates the actual prevalence of dental caries in the metropolitan area in 1987. On the other hand, the progress which had been recorded between 1977 and 1984 by francophones in relation to anglophones was partially lost in 1987. Furthermore, this study has demonstrated that the prevalence and level of dental caries treatment are highly associated with the language spoken at home and also with the family's socio-economic status.

Abstract
Previous studies have shown that herpes virus ribonucleotide reductase can be inhibited by a synthetic nonapeptide whose sequence is identical to the C-terminal of the small subunit of the enzyme. This peptide is able to interfere with normal subunit association that takes place through the C-terminal of the small subunit. In this report, we illustrate that inhibition of ribonucleotide reductases by peptides corresponding to the C-terminal of subunit R2 is also observed for the enzyme isolated from Escherichia coli, hamster, and human cells. The nonapeptide corresponding to the bacterial C-terminal sequence was found to inhibit E. coli enzyme with an IC50 of 400 microM, while this peptide had no effect on mammalian ribonucleotide reductase. A corresponding synthetic peptide derived from the C-terminal of the small subunit of the human enzyme inhibited both human and hamster ribonucleotide reductases with IC50 values of 160 and 120 microM, respectively. However, this peptide had no inhibitory activity against the bacterial enzyme. Equivalent peptides derived from herpes virus ribonucleotide reductase had no effect on either the bacterial or mammalian enzymes. Thus, subunit association at the C-terminal of the small subunit appears to be a common feature of ribonucleotide reductases. In addition, the inhibitory phenomenon observed with peptides corresponding to the C-terminal appears not only to be universal, but also specific to the primary sequence of the enzyme.

Abstract
This article details the problems related to occlusion of 13-14 year old Quebec students. The data was derived from a province wide probability sample of 1201 children in 1983-84 using Granger's Orthodontic Treatment Priority Index (TPI). The principal conclusion are: 32% of the children are in Angle's class II; 18% have an overjet of 5 mm and over; 50% have one or more teeth in minor or major displacement; treatment is mandatory or highly desirable for 13.7% and only 2.9% of the students are under treatment. The results are compared to 6 surveys of the same nature.

Abstract
Reliability and ease of use are certainly the two major qualities of a screening test or medical surveillance in the workplace. The advantages of using a reliable urinary test thus are evident: the sampling is easy, rapid, noninvasive and, therefore, well accepted. Screening tests or medical surveillance can measure the toxic chemical itself, its metabolites or its consequences on metabolism. In this study the relation between blood lead levels--the most commonly used test for screening and surveillance of saturnism--and urinary excretion of delta-aminolevulinic acid (ALA-U) was measured. The original part of this study is that it takes into account the chronobiology of ALA-U excretion. The samples are collected in the afternoon when ALA urinary excretion is at its highest level. Using a 5 mg/g of creatinine level as a threshold to detect blood lead levels equal to or higher than 60 micrograms/dL the test has an 88% sensitivity, a 91% specificity and a 37% positive predictive value. No worker whose blood lead level is equal to or higher than 65 micrograms/dL has been missed. It is suggested that using 5 mg of ALA-U/g of creatinine as a threshold to prescreen workers who should have their blood lead level measured could be useful in workplaces where lead exposure is moderate or low.

Abstract
Carotid fibromuscular dysplasia (FMD-C), a stenosing angiopathy, is frequently associated with pulsatile tinnitus. This study reports two patients, initially presenting with pulsatile tinnitus, who proved to have FMD-C. Symptoms such as tinnitus, vertigo, hemicrania, and cervicofacial hypo-esthesia might bring such a patient under an otolaryngologist's management. The paper discusses the physiopathology of the symptoms encountered with FMD-C. It is suggested that the sympathetic plexus is implicated in the manifestations of the disorder. A surgical therapeutic approach is suggested to achieve satisfactory symptomatic control.

Abstract
We have used the paradoxical antigonadal effects of LHRH agonists as a chemical castration in advanced prostatic cancer. We report early results of a phase II study on the clinical efficacy of the LHRH agonist D-Ser (TBU)6, des-Gly-NH2(10) LHRH administered to patients with stage D prostatic carcinoma. Following dose-range finding studies using either intranasal (IN) (200 micrograms twice/day or 500 micrograms twice/day) or subcutaneous (SC) administration (50 micrograms once/day, we developed a sequential combination of SC (500 micrograms three times/day for seven days) and IN regimen that was administered for 3 to 16 months to a group of 23 patients with stage D prostatic carcinoma. Initiation of therapy was associated with a clinical flare in one patient during the first week of treatment. Mean serum testosterone levels were already decreasing at one week and remained inhibited to levels inferior to 1 ng/ml after the first four weeks of treatment. Overall assessment shows that within the first six months of treatment, 26% patients were improved, 39% were stabilized, and 35% were nonresponders. Fourteen patients were followed during the next six months: 29% continued to respond, 29% escaped, 21% remained stable, and 21% were nonresponders. Histologic studies from castrated patients showed changes in spermatogenesis correlating to the degree and duration of suppression of testicular steroidogenesis without signs of toxicity. Preliminary observations on the combination of the pure antiandrogen RU 23908 with Buserelin (n = 5) or castration (n = 3) suggest that the addition of an antiandrogen does not seem to improve the patients nonresponding to other hormonal suppressive therapy (Buserelin) administered before (n = 3) or concomitantly with the antiandrogen (n = 2). Three relapsing castrate patients responded to the antiandrogen, but the response was temporary in two (eight to nine months of therapy). No side effects other than hot flashes and decreased potency are related to LHRH agonist alone or to the low-dose antiandrogen. Multicenter trials will be necessary to delineate the place of LHRH agonist alone or LHRH agonist combined with an antiandrogen in the treatment of prostatic cancer.

Abstract
Two juvenile size silicone testicular prostheses were analyzed following replacement by adult size devices after 72 and 99 months in situ. Scanning electron microscopy and electron microprobe studies were carried out on the explanted silicone prostheses and their attached tissue capsules. The material at the surface of the prostheses gave no evidence of biodeterioration. However, localized sites of calcification were observed. The adjacent tissue capsule consisted of two distinct concentric layers with different morphologies; the one adjacent to the prosthesis consisted of dense arrays of collagen fibres oriented parallel to the silicone surface and extending outward to a thickness of 100-120 microns. The outer layer was less dense, more disordered and was uneven in thickness. It contained numerous discrete particles of silicon-rich material. Technical and clinical implications of these results are discussed.
