Abstract
The present study describes the seasonal and circadian variations of the major compounds from Lippia alba leaves. SPSS was used to identify, quantify, and associate the variations in the secondary metabolites of this species through HPLC/DAD analysis of the leaves hydroethanolic extracts of six selected L. alba specimens. For the circadian study, the samples were collected at four different daily hours in each year's season. For the seasonal study, the samples were collected monthly from the same individuals for two consecutive years (2018 and 2019). These samples were analyzed and quantified using a validated HPLC method for flavonoids, iridoids, and phenyl ethanoid glycoside. Mussaenoside, acteoside, and tricin-7-O-diglucuronide showed a moderate positive correlation between their biosynthesis and the precipitation index, while epi-loganin had a moderate negative correlation. Acteoside showed a moderate positive correlation between the minimum registered temperature and its production. Compared with previous studies, a drastic reduction (about 95%) in the production of tricin-7-O-diglucuronide compared with previous study and this difference could be attributed to the plant's aging. Thus, the data demonstrated that lower temperatures and high rainfall could favor the production of the major L. alba active compounds (acteoside and tricin-7-O-diglucuronide) and that older plants harm their production.

Abstract
Funding Acknowledgements Type of funding sources: None. Purpose Cardiovascular disease (CVD) as it is known, is a multifactorial disease that needs to be addressed exactly in that way. Knowledge deficit regarding symptoms and unadjusted lifestyles are still the most relevant nursing diagnoses identified as main causes for readmissions in patients with CVD (1). Recent guidelines evidenced that after a CVD event, patients should attend to their lifestyle choices and health behaviors, in order to avoid future events, as this works in a cardioprotective way (2). Having programs structured in a way that makes it possible to involve both population and person-centered strategies all teamed up, could be a way of involving patients in their own care, tackling several recommendations at the same time. Our aim is to describe the implementation of a cardiovascular disease prevention program with a multidisciplinary approach and identify the most prevalent CVD risk factors during the first trimester of its implementation. Methods In order to improve patient outcomes post-discharge, the program was outlined as follows: firstly. a Multidisciplinary Appointment was structured, with a Cardiologist and a Nurse, where also family is invited, to assess risk factors, therapeutic adherence and quality of life. According to the patient's needs and preferences they can be assigned to the Cardiac Rehabilitation Lab, to the Education Group Sessions on CVD risk factors where a Nutritionist, Psychiatrist and Physiatrist also participate according to the sessions' topic. For more personalized approach it also comprises: Therapeutic Groups and Mental Health Appointment; Nutrition Appointment; and Nursing Counseling at Outpatient clinics for family and person-centered approach. To assess the program at its third month baseline the focus group method was used for patients and professionals perspectives. Results The program was implemented from October to December 2021. During that time 24 patients were admitted. Nursing Counseling was needed for almost all patients for different reasons. Out of those, 50% were assigned to the group sessions, 33.33% were assigned to the Cardiac Rehab, 12.5% were oriented to the Nutrition consults and 20,83% to the Mental Health consults. Even though we offered therapeutic groups as an option for some patients, none of them were willing to go. Regarding the modifiable risk factors, 70% of patients had 3 or more risk factors, showing that we do have a high risk population to tackle. Putting it into perspective, the most prevalent risk factors were dyslipidemia (70.83%), tobacco use (70.83%), obesity (54.17%) and hypertension (50%). Conclusions Managing a multidisciplinary program can be demanding, and there were several challenges to this program’s implementation such as: short-staffing, structural issues, covid-19 prevention issues, digital systems, agendas, etc.). But focusing on patients' needs and preferences, helped us to do our utmost to make this program happen.

Abstract
A new method based on Ultraviolet spectrophotometry was developed and compared with that based on HPLC for the determination and quantification of anthraquinones in the extracts of Rhamnus purshiana bark. A validated quantitative analysis of cascaroside A, cascaroside B, emodin, and aloe-emodin in these herbal products has been previously performed using HPLC coupled with diode array detector. In the HPLC analysis, all the anthraquinones showed satisfactory regression (r2 > 0.98) within the test ranges, and the recovery was in the range of 94 to 117%. The limits of detection and quantification ranged from 0.008-0.010 (μg mL-1 ) and 0.029-0.035 (μg mL-1 ), respectively. Hierarchical cluster analysis and principal component analysis showed differences in the anthraquinones determined from herbal samples. Subsequently, a simple and low-cost ultraviolet spectrophotometric methodology for the quantitative analysis of the same compounds in the extracts was applied, and all the contents were determined. A paired t-test confirmed that there were no significant differences between the two methods. Our results revealed that the developed method is simple and provides the ability to discriminate and control the quality of anthraquinones in herbal products. This article is protected by copyright.

Abstract
OBJECTIVE This article assesses the esthetic opinion of the experts involved in dental restoration (general dentists, orthodontists, prosthodontists) and laypeople. Differences in esthetic opinion among the studied groups are assessed. MATERIAL AND METHODS A questionnaire was constructed based on four photographs. A quantitative esthetic appreciation using a numerical scale was requested from four groups of observers. The final sample consisted of 434 participants: 142 laypeople, 141 general dentists, 100 orthodontists, and 51 prosthodontists. The photographs presented were based on the same lips and modified from the same intraoral photograph with asymmetric canines: the right canine was smaller than the left canine and had a lower gingival margin. A mirror image of the right canine was digitally made to create symmetry. RESULTS There were statistically significant differences (P < 0.05) in the assessments made across the different groups of observers. For all questions, the laypeople assigned significantly higher scores (P < 0.05) than the orthodontists and prosthodontists. However, there was no significant difference between groups, and all the groups considered the photograph with the larger canines to be more esthetic. The dental professionals and the laypeople disagreed the most regarding their assessment of the least esthetic image. CONCLUSION There were differences between the four observer groups in their scoring of the photographs from 0 to 10 relative to the more pleasing esthetics of closure of space with asymmetric canines. However, there were no differences in the results when evaluating each type of canine relative to the form. The canine with the most prominent shape was considered to be more esthetic by all the groups.

Abstract
Lippia alba is a popular Brazilian herb known as 'cidreira' that presents several chemotypes which exhibit different chemical profile and they are widely used as seasonings and traditional medicine. This work describes the seasonal variation of metabolites of polar extracts of carvone and linalool chemotypes, identified by GC-MS analyses of the essential oils. A methodology was elaborated in order to obtain a seasonal variation in the chemical composition of leaf employing HPLC-DAD. Acteoside, isoacteoside, geneposidic acid, 8-epi-loganin, mussaenoside, luteolin 7-O-glucoside, apigenin 7-O-glucuronide and tricin 7-O-diglucuronide have been isolated and identified for validation procedures and chromatographic analysis. Geneposidic acid was presented in all samples, in contrast to the 8-epi-loganin and, mussaenoside which were presented only in the carvone-chemotype. Acteoside was the major metabolite detected from July to November while tricin-7-O-diglucuronide was the major compound in all other months. Besides, phenylpropanoids are predominant in winter and flavonoids in summer season.

Abstract
How to handle Western blot (WB) seroindeterminate individuals for Human T-lymphotropic Virus 1/2 (HTLV-1/2) constitutes a challenge for blood banks and families. We made a cross-sectional study of 191 enzyme linked immunoassay (EIA) reactive individuals from the hematological center (HEMOCE) of Fortaleza (Brazil), examining their serological (WB) and molecular (PCR) diagnosis, and demographic profiles, as well as a possible association of their condition with other infectious pathologies and risk factors. Ethical institutional approval and personal consent were obtained. Out of 191 EIA reactive individuals, 118 were WB seroindeterminate and 73 were seropositive for HTLV-1/2. In the PCR analysis of 41 WB seroindeterminate individuals, 9 (22%) were positive and 32 (78%) were negative for HTLV-1/2. The demographic analysis indicated a trend towards a predominance of males among the seroindeterminate individuals and females in the seropositive ones. The seroindeterminate individuals were younger than the seropositive ones. We did not find any association of these conditions with syphilis, Chagas disease or HIV or hepatitis, and with risk factors such as breast-feeding, blood transfusion, STD (syphilis) and IDU.

Abstract
Cerebral aneurysmal arteriopathy of the circle of Willis is an uncommon manifestation of acquired human immunodeficiency virus (HIV) infection and up to now only 15 cases have been published in the literature. For this reason we add our experience of this rare case, and review the most important aspects related to this entity. The patient is a 6 year old male with perinatal transmitted AIDS, tetraparethic, developed symptoms characterized by episodes of dystonic postures. The computed tomography of the brain showed aneurismal arteriopathy of the circle of Willis. He had a previous normal examination. The review of the literature shows the pathological abnormalities of the affected vessels are mainly medial fibrosis, with destruction of the internal elastic lamina and intimal hyperplasia. The etiology for the vasculitis is unknown. Varicela zoster virus, as well as HIV by itself, can be related to the physiopathology of the vasculitis. On conclusion, it can be said that although uncommon, such complications are of great importance by the fact that the patients with vascular aneurismal arteriopathy are in high risk for vascular accidents, and once a diagnosis was made, death occurs in less than 6 months, according to the literature.

Abstract
Eight species of ectoparasites were collected from 166 commensal rodents, including Rattus rattus (L.), Rattus norvegicus (Berkenhout), and Mus musculus (L.), from January to December 1986, in Huambo, Angola. The oriental rat flea, Xenopsylla cheopis (Rothschild), was the predominant species with respect to mean intensity and prevalence. Other fleas collected were Ctenophthalmus (Ethioctenophthalmus) machadoi Ribeiro, Dinopsyllus (Dinopsyllus) smiti Ribeiro, and Echidnophaga gallinacea (Westwood). The mite Laelaps (Echinolaelaps) muricola Trägärdh, the louse Polyplax spinulosa (Burmeister), one species of Ixodes Latreille, and one species of Ornithonyssus Sambon were also recorded. The following represent new host records: C. machadoi from R. rattus and R. norvegicus, D. smiti from M. musculus, and L. muricola from R. rattus and M. musculus. For the first time, the monthly flea indices throughout the year are presented for Angola.

Abstract
In Huila Province of Angola, 3864 ticks were collected during a parasitological survey carried out in the rainy season from October 1990 to April 1991. The samples were collected from cattle gathered for the annual vaccination campaign against contagious bovine pleuropneumonia, anthrax and blackleg in 18 veterinary stations of six municipalities. After tick classification, the following proportions of ticks were obtained: Rhipicephalus evertsi mimeticus (27.1%), Amblyomma pomposum (26.4%), Boophilus decoloratus (19.0%), Rhipicephalus zambesiensis (9.4%), Rhipicephalus duttoni (8.3%), Hyalomma marginatum rufipes (3.8%), Hyalomma truncatum (3.0%), Rhipicephalus punctatus (2.5%) and Ixodes cavipalpus, Rhipicephalus lunulatus, Rhipicephalus turanicus, Rhipicephalus evertsi evertsi, Rhipicephalus simus, each less than 1%. These ticks are well known in southern Africa as vectors of diseases caused by protozoa and rickettsiae (babesiosis, theileriosis, anaplasmosis and cowdriosis). Control programmes against ticks and tick-borne diseases should be based on critical studies regarding costs/risks/benefits in relation to socio-economic and ecological frameworks.
