Patologie tiroidee e surrenaliche del cane e del gatto: aspetti epidemiologici, clinici e clinico-patologici

L’ipertiroidismo felino rappresenta oggi la più comune endocrinopatia della specie. I capitoli 2 e 3 costituiscono una revisione della letteratura in merito agli aspetti clinici, diagnostici e terapeutici della patologia. Il capitolo 4 indaga il ruolo della dimetilarginina simmetrica (SDMA) come marker di funzionalità renale nei gatti ipertiroidei prima e dopo terapia medica. La patologia tiroidea più comune nel cane è l’ipotiroidismo. Nello studio riportato al capitolo 5 sono state indagate le performance diagnostiche di freeT3, freeT4, rT3, 3,3-T2 e 3,5-T2, misurati tramite LC-MS/MS, nel differenziare tra cani ipotiroidei, cani con patologie non-tiroidee e cani sani. La presenza di una possibile correlazione tra la gravità della condizione clinica dei pazienti ipotiroidei, le variabili emato-chimiche e le concentrazioni sieriche di cTSH è stata valutata nel capitolo 6. Il capitolo 7 valuta l’andamento dell’SDMA in cani ipotiroidei prima e dopo supplementazione ormonale. A differenza della Sindrome di Cushing dell’uomo, che è considerata una malattia rara, nel cane l’ipercortisolismo spontaneo (HC) è una delle endocrinopatie più comuni. Gli aspetti epidemiologici dell’HC e la ricerca di un metodo di monitoraggio alternativo al test di stimolazione con ACTH nei cani trattati con Trilostano sono stati approfonditi rispettivamente nei capitoli 8 e 9. A differenza dell'HC, l'ipoadrenocorticismo primario (PH) è una patologia rara nel cane. Lo scopo dello studio riportato nel capitolo 10 consiste nel descrivere le frazioni escretorie degli elettroliti urinari nei cani con PH e di indagare se esse possano rappresentare un utile supporto alla diagnosi e al trattamento del PH canino. Il riscontro accidentale di masse surrenaliche rappresenta una criticità diagnostica. Infatti, può essere difficile distinguere morfologicamente tra lesioni corticali e midollari e tra lesioni maligne e benigne. Nel capitolo 11 vengono descritti i rilievi immunoistochimici dell'incidentaloma surrenalico nel cane e viene valutato il ruolo del Ki-67 PI come indicatore di malignità.

Studio prospettico osservazionale sull'interruzione volontaria farmacologica di gravidanza: fattori predittivi di dolore pelvico durante il trattamento

INTRODUZIONE Pochi studi in Letteratura hanno indagato la correlazione tra la sintomatologia dolorosa associata all’interruzione farmacologica di gravidanza (IVG) e i livelli d’ansia pre-trattamento. L’obiettivo primario del nostro studio è stato di valutare la correlazione tra la sintomatologia dolorosa in corso di IVG farmacologica e i livelli d’ansia pre-trattamento. Inoltre, sono stati indagati i fattori predittivi di dolore e la correlazione con l’epoca gestazionale. MATERIALI E METODI È stato condotto uno studio osservazionale, prospettico, multicentrico presso l’Unità Operativa di Ostetricia e Ginecologia dell’Azienda USL e presso l’Unità Operativa di Ginecologia dell’IRCCS Sant’Orsola Malpighi di Bologna. Sono state incluse le pazienti sottoposte a IVG farmacologica tra giugno 2021 e novembre 2021, che rispettassero i criteri di inclusione ed esclusione. Sono stati somministrati 5 questionari (GHQ-12, GAD-7, STAI-6, VAS) e raccolti i dati anamnestici ed ecografici. I potenziali fattori di rischio sono stati, quindi, selezionati per l’inclusione nell'analisi di regressione multivariata. RISULTATI Delle 242 pazienti incluse, il 38,0% ha riferito una sintomatologia dolorosa severa (VAS >70). Dall’analisi di regressione multivariata, la dismenorrea intensa è risultata essere il fattore di rischio più forte per il dolore (OR = 6,30, IC 95% 2,66 – 14,91), seguita da alti livelli di ansia valutati mediante il punteggio del GHQ-12 > 9 (OR = 3,33, IC 95% 1,43 – 7,76). Al contrario, la nostra analisi ha confermato che un precedente parto vaginale rappresentava una caratteristica protettiva contro il dolore (OR 0,26, IC 95% 0,14 – 0,50). CONCLUSIONI Nel nostro studio alti livelli d’ansia pre-trattamento e la dismenorrea sono associati ad intensa sintomatologia dolorosa, mentre il parto vaginale è risultato protettivo. L’IVG farmacologica è una metodica efficace e sicura, ma spesso associata a sintomatologia dolorosa. È quindi fondamentale delineare fattori di predittivi di dolore ed individuare le pazienti a maggior rischio a cui somministrare un’idonea terapia antalgica.

Confronto delle differenti strategie terapeutiche nei pazienti con cuore polmonare cronico tromboembolico

L'endoarteriectomia polmonare (PEA) rappresenta la terapia più efficace per il cuore polmonare cronico tromboembolico (CTEPH). Tuttavia, una quota sostanziale di pazienti sono non operabili ma hanno altre possibili strategie di trattamento: terapia medica e angioplastica polmonare(BPA). In questo studio abbiamo confrontato l'efficacia delle diverse strategie di trattamento del CTEPH nel mondo reale. Metodi: Sono stati inclusi tutti i pazienti con CTEPH riferiti al nostro centro. Abbiamo valutato l'efficacia della terapia medica a breve termine sui dati clinici, funzionali, capacità di esercizio e profilo emodinamico (indipendentemente dalle strategie di trattamento successive), l'efficacia di PEA e BPA (indipendentemente dalle strategie di trattamento precedenti/successive); Abbiamo inoltre riportato l'efficacia a lungo termine dei diversi trattamenti. Risultati: Sono stati inclusi in totale 467 pazienti (il 39% trattato solo con terapia medica, il 43% sottoposto a PEA, il 13% sottoposto a BPA e il 5% non ha ricevuto alcuna terapia). I pazienti trattati solo con terapia medica sono stati il gruppo più vecchio in termini di età, e confrontati rispetto ai pazienti sottoposti a PEA, mostravano minore capacità di esercizio, un profilo di rischio più elevato e minor miglioramento del profilo emodinamico, funzionale e della sopravvivenza. I pazienti sottoposti a BPA hanno avuto un miglioramento emodinamico inferiore rispetto ai pazienti sottoposti PEA, ma un miglioramento funzionale, dell'esercizio fisico e del profilo di rischio, e di sopravvivenza sovrapponibile ai pazienti sottoposti a PEA; la sopravvivenza è risultata migliore rispetto ai pazienti tsottoposti a sola terapia medica. Il gruppo di controllo storico di pazienti non trattati con alcuna terapia ha avuto la peggiore sopravvivenza. Conclusioni: Abbiamo confermato la superiorità della PEA rispetto a qualsiasi trattamento nei pazienti affetti da CTEPH, nei pazienti non operabili o con PH persistente/ricorrente dopo PEA, la BPA determina una prognosi migliore rispetto alla sola terapia medica.

Analysis of fragmentation cross sections of GSI 2021 data for the FOOT experiment

Hadrontherapy is a medical treatment based on the use of charged particles beams accelerated towards deep-seated tumors on clinical patients. The reason why it is increasingly used is the favorable depth dose profile following the Bragg Peak distribution, where the release of dose is almost sharply focused near the end of the beam path. However, nuclear interactions between the beam and the human body constituents occur, generating nuclear fragments which modify the dose profile. To overcome the lack of experimental data on nuclear fragmentation reactions in the energy range of hadrontherapy interest, the FOOT (FragmentatiOn Of Target) experiment has been conceived with the main aim of measuring differential nuclear fragmentation cross sections with an uncertainty lower than 5\%. The same results are of great interest also in the radioprotection field, studying similar processes. Long-term human missions outside the Earth’s orbit are going to be planned in the next years, among which the NASA foreseen travel to Mars, and it is fundamental to protect astronauts health and electronics from radiation exposure .\\ In this thesis, a first analysis of the data taken at the GSI with a beam of $^{16}O$ at 400 $MeV/u$ impinging on a target of graphite ($C$) will be presented, showing the first preliminary results of elemental cross section and angular differential cross section. A Monte Carlo dataset was first studied to test the performance of the tracking reconstruction algorithm and to check the reliability of the full analysis chain, from hit reconstruction to cross section measurement. An high agreement was found between generated and reconstructed fragments, thus validating the adopted procedure. A preliminary experimental cross section was measured and compared with MC results, highlighting a good consistency for all the fragments.

Änderung des Therapieziels am Lebensende: Effekte einer Klinik-Leitlinie [Changing the treatment goal at the end of life: effects of a guideline at a hospital].

BACKGROUND AND OBJECTIVE: Deciding about treatment goals at the end of life is a frequent and difficult challenge to medical staff. As more health care institutions issue ethico-legal guidelines to their staff the effects of such a guideline should be investigated in a pilot project.¦PARTICIPANTS AND METHODS: Prospective evaluation study using the pre-post method. Physicians and nurses working in ten intensive care units of a university medical center in Germany answered a specially designed questionnaire before and one year after issuance of the guideline.¦RESULTS: 197 analyzable answers were obtained from the first (pre-guideline) and 251 from the second (post-guideline) survey (54 % and 58 % response rate, respectively). Initially the clinicians expressed their need for guidelines, advice on ethical problems, and continuing education. One year after introduction of the guideline one third of the clinicians was familiar with the guideline's content and another third was aware of its existence. 90% of those who knew the document welcomed it. Explanation of the legal aspects was seen as its most useful element. The pre- and post-guideline comparison demonstrated that uncertainty in decision making and fear of legal consequences were reduced, while knowledge of legal aspects and the value given to advance directives increased. The residents had derived the greatest benefit.¦CONCLUSION: By promoting the knowledge of legal aspects and ethical considerations, guidelines given to medical staff can lead to more certainty when making in end of life decision.

TraumaHawk: Improving Treatment for Crash Victims Using Photos and a Smartphone App

Photographic documentation of crashed vehicles at the scene can be used to improve triage of crash victims. A U.S. expert panel developed field triage rules to determine the likelihood of occupants sustaining serious injuries based on vehicle damage that would require transport to a trauma center (Sasser et al., 2011). The use of photographs for assessing vehicle damage and occupant compartment intrusion as it correlates to increased injury severity has been validated (Davidson et al., 2014). Providing trauma staff with crash scene photos remotely could assist them in predicting injuries. This would allow trauma care providers to assess the appropriate transport, as well as develop mental models of treatment options prior to patient arrival at the emergency department (ED). Crash-scene medical response has improved tremendously in the past 20-30 years. This is in part due to the increasing number of paramedics who now have advanced life support (ALS) training that allows independence in the field. However, while this advanced training provides a more streamlined field treatment protocol, it also means that paramedics focused on treating crash victims may not have time to communicate with trauma centers regarding crash injury mechanisms. As a result, trauma centers may not learn about severe trauma patients until just a few minutes before they arrive. The information transmitted by the TraumaHawk app allows interpretation of injury mechanisms from crash scene photos at the trauma center, providing clues about the type and severity of injury. With strategic crash scene photo documentation, trained trauma professionals can assess the severity and patterns of injury based on exterior crush and occupant intrusion. Intrusion increases the force experienced by vehicle occupants, which translates into a higher level of injury severity (Tencer et al., 2005; Assal et al., 2002; Mandell et al., 2010). First responders have the unique opportunity to assess the damaged vehicle at the crash scene, but often the mechanism of injury is limited or not even relayed to ED trauma staff. To integrate photographic and scene information, an app called TraumaHawk was created to capture images of crash vehicles and send them electronically to the trauma center. If efficiently implemented, it provides the potential advantage of increasing lead-time for preparation at the trauma center through the crash scene photos. Ideally, the result is better treatment outcomes for crash victims. The objective of this analysis was to examine if the extra lead-time granted by the TraumaHawk app could improve trauma team activation time over the current conventional communication method.

Urgences vitales au cabinet médical: implications pour la formation et l'equipement du médecin de premier recours [Life-threatening emergencies at the office: implications for medical education and equipment of the primary care physician].

Every medical practitioner is confronted on a daily basis with emergencies. Among these, life-threatening emergencies can have disastrous consequences in term of morbidity and mortality; 22 cardiac arrests and 10 deaths were reported among the 1,650 Swiss practices during a 5 year period. The occurrence of life-threatening emergencies at the office necessitates, according to the type and place of the practice, the skills of the practitioner and the organization of his practice, the implementation of procedures, equipments (for example room equipped with a defibrillator, respiratory nebulizer, splints, emergency drugs) and specific continuous education programs that should be encouraged and made available to the whole medical corporation.

Short-term follow-up of exercise training program and beta-blocker treatment on quality of life in dogs with naturally acquired chronic mitral valve disease

This study aimed to evaluate the effects of carvedilol treatment and a regimen of supervised aerobic exercise training on quality of life and other clinical, echocardiographic, and biochemical variables in a group of client-owned dogs with chronic mitral valve disease (CMVD). Ten healthy dogs (control) and 36 CMVD dogs were studied, with the latter group divided into 3 subgroups. In addition to conventional treatment (benazepril, 0.3-0.5 mg/kg once a day, and digoxin, 0.0055 mg/kg twice daily), 13 dogs received exercise training (subgroup I; 10.3±2.1 years), 10 dogs received carvedilol (0.3 mg/kg twice daily) and exercise training (subgroup II; 10.8±1.7 years), and 13 dogs received only carvedilol (subgroup III; 10.9±2.1 years). All drugs were administered orally. Clinical, laboratory, and Doppler echocardiographic variables were evaluated at baseline and after 3 and 6 months. Exercise training was conducted from months 3-6. The mean speed rate during training increased for both subgroups I and II (ANOVA, P>0.001), indicating improvement in physical conditioning at the end of the exercise period. Quality of life and functional class was improved for all subgroups at the end of the study. The N-terminal pro-brain natriuretic peptide (NT-proBNP) level increased in subgroup I from baseline to 3 months, but remained stable after training introduction (from 3 to 6 months). For subgroups II and III, NT-proBNP levels remained stable during the entire study. No difference was observed for the other variables between the three evaluation periods. The combination of carvedilol or exercise training with conventional treatment in CMVD dogs led to improvements in quality of life and functional class. Therefore, light walking in CMVD dogs must be encouraged.

LIFE QUALITY of PEOPLE INFECTED BY HIV WITH OR WITHOUT ANTIRETROVIRAL TREATMENT

The "HIV/Aids-Quality of Life" (HAT-Qol) is a specific multifunctional instrument used to measure the life quality of HIV infected persons. It is divided into nine domains: general activity, sexual activity, secrecy about HIV seropositivity, concern about health, financial concern, awareness about HIV, satisfaction with life, issues about medications and belief in the doctor. The current study analyzed the life quality of HIV infected individuals-who attended the DST/Aids Program in Maringa city, Parana state-regarding the use or not of antiretroviral therapy (TARV) and their demographic, epidemiological and clinical characteristics. Data were collected by retrospective analysis from 1,200 medical charts of patients registered in the program. The HAT-Qol instrument was applied before routine medical consultation. One hundred and sixty-nine patients, who had HIV infection confirmed, were divided into two groups, G1 with 118 individuals receiving antiretroviral therapy and G2 with 51 individuals who were not under this therapy.Result analysis, regarding social and demographic characteristics, revealed no difference among responses related to gender, educational degree and sexual option. Age influenced satisfaction with sexual activity and marital status. Regarding HIV awareness, the lowest response index or worst quality of life came from, respectively, men between 50 and 69 years old and patients who did not have regular partners compared with the ones who did. Additionally, it was observed that the time of diagnosis influenced general activities, HIV awareness, concern about health and financial issues, satisfaction with life and topics about medications. The variables were compared in both groups. There was no influence on the use or not of antiretroviral therapy regarding age, sexual activity, HIV diagnosis time and the domains that evaluated general activities, financial concern, awareness of HIV and satisfaction with life. In relation to time of diagnosis, there was an influence only in persons who had been diagnosed two or three years before, in which a lower quality of life was observed among individuals who were not under antiretroviral therapy. It was not possible to compare variables about medication use, HIV plasmatic viral rate ant time of diagnosis, because G2 individuals were not receiving the antiretroviral therapy. Furthermore, no comparison was made regarding marital status and HIV awareness, because there were no married individuals in G2. Thus, the analysis of the results showed that the use of antiretroviral treatment did not influence the life quality of HIV patients studied by the HAT-Qol scale.

High-risk drug use and sexual behaviors among out-of-treatment drug users: An aging and life course perspective

High-risk injection drug use and the sexual behaviors that accompany it have large social and financial costs. Tailored treatments have been shown to successfully reduce high-risk behaviors. However, little is known about how age and age at first drug use are related to high-risk injection or sex behaviors. The current study draws on life course theory and hypothesizes that age will have a strong relationship with high-risk behaviors of out-of-treatment drug users. Data from the NIDA Cooperative Agreement was used to analyze the relationship between (1) age, and (2) age at first drug use with seven high-risk injection and sexual behavior variables. Negative binomial regression models revealed that high-risk sexual behavior decreases between 15.8 and 20.9% with each decade of age, while high-risk injection behavior increases between 32 and 67% with each decade of age after the addition of demographic controls. Both high-risk injection and high-risk sex behaviors are significantly reduced with a delayed age at first drug use. Previous research promotes interventions to reduce the high-risk sexual behaviors of older drug users. The current study suggests a refocusing of public health efforts on the high-risk injection habits of older drug users.^

Influence of gender and life stressors on longitudinal depression treatment outcomes among older primary care patients

Purpose: Depression in older females is a significant and growing problem. Females who experience life stressors across the life span are at higher risk for developing problems with depression than their male counterparts. The primary aim of this study was (a) to examine gender-specific differences in the correlates of depression in older primary care patients based on baseline and longitudinal analyses; and (b) to examine the longitudinal effect of biopsychosocial risk factors on depression treatment outcomes in different models of behavioral healthcare (i.e., integrated care and enhanced referral). Method: This study used a quantitative secondary data analysis with longitudinal data from the Primary Care Research in Substance Abuse and Mental Health for Elderly (PRISM-E) study. A linear mixed model approach to hierarchical linear modeling was used for analysis using baseline assessment, and follow-up from three-month and six-month. Results: For participants diagnosed with major depressive disorder female gender was associated with increased depression severity at six-month compared to males at six-month. Further, the interaction between gender and life stressors found that females who reported loss of family and friends, family issues, money issues, medical illness was related to higher depression severity compared to males whereas lack of activities was related to lower depression severity among females compared to males. Conclusion: These findings suggest that gender moderated the relationship between specific life stressors and depression severity similar to how a protective factor can impact a person's response to a problem and reduce the negative impact of a risk factor on a problem outcome. Therefore, life stressors may be a reliable predictor of depression for both females and males in either behavioral health treatment model. This study concluded that life stressors influence males basic comfort, stability, and survival whereas life stressors influence females' development, personal growth, and happiness; therefore, life stressors may be a useful component to include in gender-based screening and assessment tools for depression. ^

Transcutaneous Tibial Nerve Stimulation In The Treatment Of Lower Urinary Tract Symptoms And Its Impact On Health-related Quality Of Life In Patients With Parkinson Disease: A Randomized Controlled Trial.

A randomized controlled trial study was performed to evaluate the efficacy of transcutaneous tibial nerve stimulation (TTNS) and sham TTNS, in patients with Parkinson disease (PD) with lower urinary tract symptoms (LUTS). Randomized controlled trial. Thirteen patients with a diagnosis of PD and bothersome LUTS were randomly allocated to one of the following groups: Group I: TTNS group (n = 8) and group II: Sham group (n = 5). Both groups attended twice a week during 5 weeks; each session lasted 30 minutes. Eight patients received TTNS treatment and 5 subjects allocated to group II were managed with sham surface electrodes that delivered no electrical stimulation. Assessments were performed before and after the treatment; they included a 3-day bladder diary, Overactive Bladder Questionnaire (OAB-V8), and the International Consultation on Incontinence Quality of Life Questionnaire Short Form (ICIQ-SF), and urodynamic evaluation. Following 5 weeks of treatment, patients allocated to TTNS demonstrated statistically significant reductions in the number of urgency episodes (P = .004) and reductions in nocturia episodes (P < .01). Participants allocated to active treatment also showed better results after treatment in the OAB-V8 and ICIQ-SF scores (P < .01, respectively). Urodynamic testing revealed that patients in the active treatment group showed improvements in intravesical volume at strong desire to void (P < .05) and volume at urgency (P < .01) when compared to subjects in the sham treatment group. These findings suggest that TTNS is effective in the treatment of LUTS in patients with PD, reducing urgency and nocturia episodes and improving urodynamic parameters as well as symptom scores measured by the OAB-V8 and health-related quality-of-life scores measured by the ICIQ-SF.

Nausea, Vomiting And Quality Of Life Of Patients With Cancer Undergoing Antineoplastic Treatment: An Evaluation By Pharmacists.

This study aims to evaluate the frequency and severity of nausea and vomiting using two different instruments and relate them to quality of life (QOL) in patients with cancer receiving antineoplastic treatment. Severity of chemotherapy-induced nausea and vomiting (CINV) was measured by Common Terminology Criteria for Adverse Events (CTCAE) and a numerical scale. QOL was assessed using the Functional Assessment of Cancer Therapy-General questionnaire. Of the 50 patients studied, 60.0% reported nausea (40.0% CTCAE grade 1; 66.7% moderate intensity on numerical scale) and 30.0% reported vomiting (46.7% CTCAE grades 1 and 2, each; 66.7% moderate intensity on numerical scale). CINV did not influence overall QOL. The frequency of CINV was high. There was no association between nausea/vomiting and overall QOL.

Clinical outcomes of long-acting injectable risperidone in patients with schizophrenia: six-month follow-up from the Electronic Schizophrenia Treatment Adherence Registry in Latin America

Background: Risperidone long-acting injection (RLAI) has been shown to be efficacious, improve compliance, and increase long-term retention rate on therapy. The aim of this work was to determine the effect of RLAI on clinical outcome and hospitalization rate in patients with schizophrenia or schizoaffective disorder enrolled in the electronic Schizophrenia Treatment Adherence Registry in Latin America. Methods: Data were collected at baseline, retrospectively for the 12 months prior to baseline, and prospectively every three months for 24 months. Hospitalization prior to therapy was assessed by a retrospective chart review. Efficacy and functioning were evaluated using Clinical Global Impression of Illness Severity (CGI-S), Personal and Social Performance (PSP), and Global Assessment of Functioning (GAF) scores. Relapse and treatment were also registered. Results: Patients were recruited in Mexico (n = 53), Brazil (n = 11), and Colombia (n = 15). Sixty-five percent (n = 52) were male, and mean age was 32.9 years. Patients were classified as having schizophrenia (n = 73) or schizoaffective disorder (n = 6). The mean dose of RLAI at six months was 34.1 mg (standard deviation = 10.2 mg). The percentage of hospitalized patients before treatment was 28.2% and 5.1% at six months after initiating RLAI (P < 0.001). Significant changes were registered on CGI-S, GAF, and PSP scores. Conclusions: RLAI was associated with an improvement in clinical symptoms and functioning, and a greater reduction in hospitalization.
