RESUMEN

BACKGROUND: The term end-stage renal disease (ESRD) refers to the final stage of chronic kidney disease. Not all ESRD patients are suitable for dialysis treatment, which despite its advantages, is not without risks. Shared nephrologist-patient decision-making could be beneficial at this stage, yet little is known about such practices in Israel. This study aimed at examining the practice of shared decision-making (SDM) between nephrologists and ESRD patients in Israel, while exploring related conflicts, ethical dilemmas, and considerations. METHODS: The descriptive-quantitative approach applied in this study included a validated questionnaire for nephrologists, based on Emanual and Emanual (1992). The survey, which was distributed via social-media platforms and snowball sampling, was completed by 169 nephrologists. Data analysis included t-tests for independent samples, f-tests for analysis of variance, and t-tests and f-tests for independence. Descriptive analysis examined attitudes towards SDM in end-of-life care for ESRD patients. RESULTS: The findings show that the research sample did not include nephrologists who typically act according to the paternalistic decision-making style. Rather, 53% of the respondents were found to act in line with the informative decision-making style, while 47% act according to the interpretive decision-making style. Almost 70% of all respondents reported their discussing quality-of-life with patients; 63.4% provide prognostic assessments; 61.5% inquire about the patient's desired place of death; 58.6% ask about advance directives or power-of-attorney; and 57.4% inquire about cultural and religious beliefs in end-of-life treatment. Additionally, informative nephrologists tend to promote the patients' autonomy over their health (P < 0.001); they are also in favor of conservative treatment, compared to paternalistic and interpretive nephrologists, and use less invasive methods than other nephrologists (P = 0.02). CONCLUSIONS: Nephrologists in Israel only partially pursue an SDM model, which has the potential to improve quality-of-care for ESRD patients and their families. SDM programs should be developed and implemented for increasing such practices among nephrologists, thereby expanding the possibilities for providing conservative care at end-of-life.

RESUMEN

Oedema disease (OD) in weaned piglets is caused by shigatoxigenic Escherichia coli (STEC), which produces the Stx2e toxin. The disease is controlled by early vaccination (for example, with Ecoporc Shiga®). Iron-deficiency anaemia (IDA) and cystoisosporosis are the most common clinical conditions in piglets. These conditions are managed mainly by the intramuscular injection of iron and application of toltrazuril (for example, Forceris®). In the present study, we sought to evaluate any effect on the efficacy of OD vaccination and iron/anticoccidial treatment resulting from a simultaneous application. An evaluation was carried out by measuring the development of neutralising antibodies against the Stx2e toxin, hematinic indices and oocysts shedding. Six litters from Stx2e-antibody-negative sows were included in the study, with 12 piglets in each litter. The piglets were randomly allocated into two groups on their second day of life (DOL): (T1) iron/anticoccidial treatment and vaccine were administered on different days, and (T2) products were administered simultaneously. Blood samples were collected to determine the levels of serum-neutralising antibodies, haemoglobin and haematocrit. Faecal matter was examined for the presence of oocysts of Cystoisospora suis. No differences were found between the two groups in terms of the development of neutralising antibodies. The levels of haemoglobin and haematocrit were lower (p < 0.05 and p = 0.08, respectively) when iron/anticoccidial treatment and vaccine were applied simultaneously but within the optimal range, based on current interpretive criteria for IDA. Oocysts were not detected in the faecal samples from the animals in either group. In conclusion, we found that, under the conditions of our study, the efficacy of OD vaccination and iron/anticoccidial treatment was not affected by the simultaneous use.

RESUMEN

The aim of the present study was to assess the short-term behavioral and physiological responses of piglets to different treatment protocols for the control of iron-deficiency anemia (IDA) and cystoisosporosis. Piglets were treated with either (1) an injection of iron combined with an oral application of toltrazuril (TLZ) by drenching or (2) a combination injection of TZL + gleptoferron; the behavior of the piglets was then evaluated. For this study, 288 piglets were divided into three experimental groups: 96 piglets were kept untreated (control group); 96 piglets received an oral administration of a generic TZL-based anticoccidial agent (20 mg/kg BW) along with intramuscular administration of iron dextran (200 mg/mL; 1 mL/piglet) at the same handling (oral + parenteral group, O + P); and 96 piglets received an intramuscular application of the combination product (parenteral group, P). For each treated piglet, the total handling time, flight reaction, and the intensity and frequency of vocalizations were determined using the methodology described by Scollo et al. (2020). Piglets in the O + P group were found to emit more screams during treatment administration than animals in the P group (21.05% vs. 8.42% of animals; p < 0.05). Piglets in the O + P group reacted worse to manipulation and oral administration because a higher percentage of animals continued to fidget even after handling (32.63% vs. 12.63%; p < 0.05). Differences in growth performance between the groups were not observed in our study (p > 0.05). In conclusion, the administration of a combination product reduced stress during administration, as indicated by reduced vocalizations and reactions to manipulation.

RESUMEN

Older lesbian, gay, bisexual, trans, and queer (LGBTQ) individuals tend to live alone, mostly without children and with scarce support from nuclear family members or biological kin. Moreover, traditional resources may not suit their specific end-of-life care needs. While studies have examined these topics in general, they lack focus on end-of-life needs, care, and planning in Israel. Moreover, research on this topic among members of LGBTQ communities is specifically lacking. This study, therefore, aimed at identifying and understanding the attitudes, perceptions, and meanings of older LGBTQ individuals in Israel regarding their needs and challenges, as they age and near end of life. The phenomenological qualitative research methodology was applied, following the interpretive approach. Twenty-one middle-aged and older LGBTQ individuals in Israel, aged ≥ 55, participated in the study. In-depth semi-structured interviews, conducted from November 2020 to April 2021, were audio-recorded, transcribed, and de-identified. Five themes emerged from the interviews: (1) Experiences of loneliness, marginalization, and trauma, and coping through liberation; (2) ageism and exclusion of older adults; (3) elastic and challenging relationships; (4) end of life as reverting into the closet and heteronormativity; and (5) death as a source of generativity and creativity. The study demonstrates that loneliness is an existential experience, exacerbated by the intersectionality of LGBTQ communities. In turn, chosen family members play a minimal role in the end-of-life care of their loved ones. While conveying ambivalence toward social services and housing for the aging, participants in this study expressed fear of being discriminated against and having to re-enter the closet as they age. Ageism and end of life do not represent finality and extinction, yet instead, signify hope and revival. Following Sandberg and Marshall's (2017) concept of queering aging futures, this study refines our understanding of life courses, demonstrating that living and thriving in old age could be positive and desirable. As such, ageism and end of life do not necessarily represent finality and extinction, and may instead signify hope and revival. The unique challenges associated with family and social support of older adults who are LGBTQ members, and their implications on care, deserve further research and are important for practice.

RESUMEN

Objectives: Exploring the experiences, perceptions and meanings of family members and close friends of Israeli individuals who sought aid-in-dying outside Israel. Methods: Using the phenomenological-interpretive approach, a qualitative research design was employed, based on ten in-depth semi-structured interviews with Israelis who had provided support for a relative who embarked on suicide tourism. Results: The following five themes emerged from interviews: (1) facilitators for supporting an individual requesting suicide tourism; (2) choosing death and actively making the decision to die; (3) the meaning of traveling to die; (4) offering support throughout the process; and (5) facilitating procedures after death. Conclusion: The participants spoke of the active role that they played in their relative's suicide-tourism journey. They conveyed conflicting emotions and values regarding the decision at hand, the ability to say goodbye thanks to their pre-planned death, helping to reduce their suffering and burden, and dealing with the challenge of disclosing the deceased's plans, before and after the act, as well as their own involvement in the process. Relatives of suicide-tourism patients should receive professional support during and following this difficult process.

RESUMEN

Iron deficiency anemia (IDA) and cystoisosporosis are the most common clinical conditions of fast-growing piglets. Until now, IDA and cystoisosporosis have been managed by intramuscular injection of iron complexes (such as dextran or gleptoferron) and oral administration of toltrazuril. Recently, a new combination product containing toltrazuril and gleptoferron for intramuscular application (Forceris®) has been registered. The objective of this study was to compare the pharmacokinetic profiles of toltrazuril and its main metabolite, toltrazuril sulfone, following a single oral (Baycox®) or intramuscular (Forceris®, a toltrazuril-iron combination product) administration at 20 mg/kg to young suckling piglets. The orally treated piglets were also supplemented with iron (Gleptosil®), and the hematinic activities were compared. Piglets in both groups received comparable doses. The peak concentration (Cmax) of toltrazuril after intramuscular administration was 11% lower than that after oral administration (p = .376). However, the exposure to toltrazuril (AUC) was significantly increased (40% higher) when toltrazuril was administered intramuscularly (p = .036). The Cmax and AUC values of the active metabolite, toltrazuril sulfone were 39% and 34% higher, respectively, after intramuscular administration (p = .007 and 0.008, respectively). Piglets in both groups were properly protected against IDA. In conclusion, a higher relative bioavailability of toltrazuril is observed when toltrazuril is administered intramuscularly.

RESUMEN

OBJECTIVE: This study aims to examine the perspectives of neonatologists in Israel regarding resuscitation of preterm infants born at 22-24 weeks gestation and their consideration of parental preferences. The factors that influence physicians' decisions on the verge of viability were investigated, and the extent to which their decisions align with the national clinical guidelines were determined. STUDY DESIGN: Descriptive and correlative study using a 47-questions online questionnaire. RESULTS: 90 (71%) of 127 active neonatologists in Israel responded. 74%, 50% and 16% of the respondents believed that resuscitation and full treatment at birth are against the best interests of infants born at 22, 23 and 24 weeks gestation, respectively. Respondents' decisions regarding resuscitation of extremely preterm infants showed significant variation and were consistently in disagreement with either the national clinical guidelines or the perception of what is in the best interest of these newborns. Gender, experience, country of birth and the level of religiosity were all associated with respondents' preferences regarding treatment decisions. Personal values and concerns about legal issues were also believed to affect decision-making. CONCLUSION: Significant variation was observed among Israeli neonatologists regarding delivery room management of extremely premature infants born at 22-24 weeks gestation, usually with a notable emphasis on respecting parents' wishes. The current national guidelines do not fully encompass the wide range of approaches. The country's guidelines should reflect the existing range of opinions, possibly through a broad survey of caregivers before setting the guidelines and recommendations.

RESUMEN

The practice of suicide tourism refers to the traveling of individuals to other countries to seek legally permitted assisted suicide. This study employed a descriptive qualitative research approach exploring how right-to-die organizations perceive suicide tourism and its implications on the right-to-die. Five themes emerged following the analysis of 12 in-depth interviews with activists from right-to-die organizations and 13 relevant documents: (1) unequivocal attitudes toward suicide tourism; (2) relationships between the organizations and the media; (3) acting to change the legal status of the right-to-die; (4) the role of the family in interactions between the organization and the person seeking assistance; and (5) reciprocal relations between the organizations and the physicians. The findings reveal ambivalent attitudes within such organizations toward suicide tourism, inherent tension among participating physicians, and complex relationships between assisted suicide, palliative care, and the physicians' duty to promote individual choice at end-of-life.

RESUMEN

In this study the efficacy of an intramuscular formulation of toltrazuril combined with gleptoferron for the control of porcine cystoisosporosis caused by Cystoisospora suis was investigated. The study was carried out on three Belgian farms with a confirmed history of C. suis infections. As none of the farms implemented a standardized toltrazuril treatment regimen for their piglets, the presence of resistant C. suis strains seems improbable. In total 90 litters, representing 1249 piglets, were included in the study and randomly allocated to either the treatment or control group. Piglets in the treatment group received a single intramuscular injection, containing 45 mg toltrazuril and 200 mg gleptoferron, between 1 and 3 days of age. Piglets in the control group received a single injection with only 200 mg gleptoferron. The effect of treatment on oocyst excretion, expressed in oocysts per gram of feces (OPG), average daily weight gain (ADG) and mortality was determined both pre- and post-weaning. A significant decrease in OPG as well as a decrease in the number of litters (pre-weaning) and pens (post-weaning) that tested positive for cystoisosporosis, was observed in the treated animals compared to the controls. Furthermore, treatment resulted in an increased ADG during the period from day 1 to day 21 (p-value: 0.03881). There was no significant difference in mortality observed between the treatment group to the control group (p-value: 0.2167). To our knowledge, this is the first report on the effect of toltrazuril on oocyst excretion after weaning. This finding highlights the potential long-term benefits of the treatment beyond the initial administration.

RESUMEN

BACKGROUND: The COVID-19 pandemic led to an intensified fear and threat of dying, combined with dying and grieving in isolation, in turn significantly impacting nursing in end-of-life situations. The study aims (1) to understand the lived experiences of nurses who provided care to end-of-life patients during COVID-19; and (2) to explore whether providing care under such circumstances altered the perspectives of these nurses regarding end-of-life care. METHODS: Applying the phenomenological-interpretive qualitative approach, 34 in-depth semi-structured interviews were conducted between March 2020-May 2021 with nurses from eight hospitals in Israel who were recruited through purposive and snowball sampling. Thematic analysis was applied to identify major themes from the interviews. RESULTS: Five main themes emerged from the analysis, including: (1) a different death; (2) difficulties in caring for the body after death; (3) the need for family at end-of-life; (4) weaker enforcement of advance care directives; and (5) prolonging the dying process. DISCUSSION: During the pandemic, nurses encountered numerous cases of death and dying, while facing ethical and professional issues regarding end-of-life care. They were required to administer more aggressive care than usual and even necessary, leading to their increased moral distress. The nurses' ethical concerns were also triggered by the requirement to wrap the corpse in black garbage-like bags to prevent contagion, which they felt was abusing the dead. The findings also demonstrate how family presence at end-of-life is important for the nursing staff as well as the patient. Finally, end-of-life situations during the pandemic in Israel were managed in an individual and personal manner, rather than as a collective mission, as seen in other countries. CONCLUSIONS: The study offers insights into the nurses' attitudes towards death, dying, and end-of-life care. An emphasis should be placed on the key elements that emerged in this study, to assist nurses in overcoming these difficulties during and after medical crises, to enhance end-of-life care and professionalism and decrease burnout.

RESUMEN

BACKGROUND: End-stage renal disease (ESRD) is the final stage of chronic kidney disease. Yet dialysis is not suitable for all ESRD patients. Moreover, while shared decision-making (SDM) is the preferred model for making medical decisions, little is known about SDM between nephrology nurses and ESRD patients in Israel. RESEARCH OBJECTIVE: Assessing the views, attitudes, practices, and ethical dilemmas of nephrology nurses in Israel regarding SDM with ESRD patients. METHODS: Using the descriptive quantitative approach, questionnaires were completed by 444 nephrology nurses in Israel. In addition to conducting descriptive statistics, t-tests for independent samples, f-tests for analysis of variance, and both tests for independence were also performed. ETHICAL CONSIDERATIONS: The research aims, expected advantages and risks have been explained to respondents before completing the questionnaire to secure informed consent. Anonymity and confidentiality were ensured throughout the study. The study was approved by the Research Ethics Committee at the University of Haifa (Approval # 411/21). RESULTS: About one-third (30%-36.5%) of nurses reported discussing quality of life issues with ESRD patients, asking about their advance directives/power of attorney, exploring cultural/religious beliefs in end-of-life care, and ask about their preferred place of death. Nurses who convey high levels of patient-centered care (68.9%, p<0.0001), have high end-of-life training (76.2%, p<0.0001), and report cooperating with interdisciplinary teams (63.8%, p = 0.0415), also reported higher SDM practices than others. Nurses who refer less patients to palliative care (70%, p<0.0001) reported higher involvement in SDM compared to other nurses. CONCLUSIONS: Nephrology nurses in Israel do not tend to implement the SDM model, despite its potential for improving quality of life for ESRD patients and their families and increasing conservative care options. Policy makers and educators in Israel should develop and implement training programs and support in the workplace, to enhance SDM between nephrology nurses and ESRD patients.

RESUMEN

BACKGROUND: Neonatal coccidiosis is a common and important disease of suckling piglets in modern farming caused by Cystoisospora suis. Prevalence rates are high, namely, in Portugal, although no recent data are available. The metaphylactic administration of a single dose of toltrazuril and hygienic measures are the backbone of control strategies on positive farms. However, several studies have shown that these programs are not always effective, underlining the need to revise the risk factors and control strategies currently applied. The present study evaluated C. suis prevalence on Portuguese farms and assessed the risk factors associated with facilities and farm rearing practices. RESULTS: From the 27 tested farms, 23 were positive to Cystoisopora suis (85.2%). In total, 258 litters were sampled (accounting for 516 samples-2 samples per litter), with an average of 59.7% of positive litters per positive farm. Faecal pools from litters, in which liquid faeces predominated had a higher probability of containing oocysts than litter pools with mainly solid (Odds Ratio: 9.87; p < 0.0001) or pasty faeces (OR: 7.05; p = 0.001), and samples obtained from younger animals had higher oocyst counts (coefficient: - 0.0720; 95% CI - 0.125; - 0.019). No significant effect of toltrazuril administration was observed on the positivity rate, and none of the tested farms used disinfectants with official claims against parasites and known anticoccidial effects (e.g., cresol-based products). CONCLUSIONS: The C. suis prevalence on Portuguese swine farms appears to be similar to the prevalence found in other European countries. Repeated sampling of the same litter and the use of autofluorescence microscopy after a modified Ritchie technique seems to have increased sensitivity and consequently the detection rate of positive litters. Finally, despite the common use of oral toltrazuril, C. suis control programs appear to not always be effective (based on the detection of oocysts in faecal samples), suggesting the need to revise the control strategies applied in the field, including management factors and choices of disinfectant products.

RESUMEN

Introduction: Enterotoxigenic Escherichia coli (ETEC) infections are the most common cause of secretory diarrhea in suckling and post-weaning piglets. For the latter, Shiga toxin-producing Escherichia coli (STEC) also cause edema disease. This pathogen leads to significant economic losses. ETEC/STEC strains can be distinguished from general E. coli by the presence of different host colonization factors (e.g., F4 and F18 fimbriae) and various toxins (e.g., LT, Stx2e, STa, STb, EAST-1). Increased resistance against a wide variety of antimicrobial drugs, such as paromomycin, trimethoprim, and tetracyclines, has been observed. Nowadays, diagnosing an ETEC/STEC infection requires culture-dependent antimicrobial susceptibility testing (AST) and multiplex PCRs, which are costly and time-consuming. Methods: Here, nanopore sequencing was used on 94 field isolates to assess the predictive power, using the meta R package to determine sensitivity and specificity and associated credibility intervals of genotypes associated with virulence and AMR. Results: Genetic markers associated with resistance for amoxicillin (plasmid-encoded TEM genes), cephalosporins (ampC promoter mutations), colistin (mcr genes), aminoglycosides (aac(3) and aph(3) genes), florfenicol (floR), tetracyclines (tet genes), and trimethoprim-sulfa (dfrA genes) could explain most acquired resistance phenotypes. Most of the genes were plasmid-encoded, of which some collocated on a multi-resistance plasmid (12 genes against 4 antimicrobial classes). For fluoroquinolones, AMR was addressed by point mutations within the ParC and GyrA proteins and the qnrS1 gene. In addition, long-read data allowed to study the genetic landscape of virulence- and AMR-carrying plasmids, highlighting a complex interplay of multi-replicon plasmids with varying host ranges. Conclusion: Our results showed promising sensitivity and specificity for the detection of all common virulence factors and most resistance genotypes. The use of the identified genetic hallmarks will contribute to the simultaneous identification, pathotyping, and genetic AST within a single diagnostic test. This will revolutionize future quicker and more cost-efficient (meta)genomics-driven diagnostics in veterinary medicine and contribute to epidemiological studies, monitoring, tailored vaccination, and management.

RESUMEN

Oedema disease (OD) in piglets is one of the most important pathologies, as it causes significant losses due to the high mortality because of the Shiga toxin family, which produces Escherichia coli (STEC) strains. The main toxin responsible for the characteristic pathologies in pigs is Shiga toxin 2 subtype e (Stx2e). Moreover, there is growing evidence that Stx's family of toxins also targets immune cells. Therefore, this study evaluated the effect of different concentrations of Stx2e on porcine immune cells. Porcine peripheral blood mononuclear cells were pre-incubated with Stx2e, at three different concentrations (final concentrations of 10, 500, and 5000 CD50/mL) and with a negative control group. Cells were then stimulated with polyclonal mitogens: concanavalin A, phytohemagglutinin, pokeweed mitogen, or lipopolysaccharides. Cell proliferation was assessed by BrdU (or EdU) incorporation into newly created DNA. The activation of the lymphocyte subsets was assessed by the detection of CD25, using flow cytometry. The toxin significantly decreased mitogen-driven proliferation activity, and the effect was partially dose-dependent, with a significant impact on both T and B populations. The percentage of CD25+ cells was slightly lower in the presence of Stx2e in all the defined T cell subpopulations (CD4+, CD8+, and γδTCR+)-in a dose-dependent manner. B cells seemed to be the most affected populations. The negative effects of different concentrations of Stx2e on the immune cells in this study may explain the negative impact of the subclinical course of OD.

RESUMEN

Piglet coccidiosis is a parasitic disease caused by the protozoan Cystoisospora suis, which is regarded as the most prevalent gastrointestinal parasite in intensive pig farms. Despite the availability of highly effective chemo-metaphylaxis (toltrazuril), coccidiosis is still prevalent in European and other countries. We conducted a cross-sectional study on swine farms in Brazil, to assess the prevalence of Cystoisospora suis in fecal samples and determined the associated factors. In total, 666 litters from 50 farms were sampled twice within one week between samplings (mean age at sampling: 10.75 and 17.7 days). Of 666 litters, 225 (33.8%) were positive at least once, and the expected within farm prevalence of C. suis oocysts was 32.9% (25.4-41.3%; 95% confidence interval). Oocysts were more prevalent in fecal samples collected from farms with diarrhea (odds ratio = 6.75). The room temperature was also positively associated with oocyst detection; a one-degree increase in room temperature increased the chance of a litter being positive by 23.2%. Up-to-date, this is the most comprehensive technical evidence of factors associated with C. suis infection in Brazilian industrial piglet farms.

RESUMEN

Background: Nurse champions are front-line practitioners who implement innovation and reconstruct policy. Purpose: To understand through a network theory lens the factors that facilitate nurse champions' engagement with radical projects, representing their actions as street-level bureaucrats (SLBs). Materials and methods: A personal-network survey was employed. Ninety-one nurse champions from three tertiary medical centers in Israel participated. Findings: Given high network density, high levels of advice play a bigger role in achieving high radicalness compared with lower levels advice. High network density is also related to higher radicalness when networks have high role diversity. Discussion: Using an SLB framework, the findings suggest that nurse champions best promote adoption of innovation and offer radical changes in their organizations through professional advice given by colleagues in their field network. Healthcare organizations should establish the structure and promote the development of dense and heterogeneous professional networks to realize organizations' goals and nurses' responsibility to their professional employees, patients, and society.

BACKGROUND: Following the increased presence of the Right-to-Die Movement, improved end-of-life options, and the political and legal status of aid-in-dying around the globe, suicide tourism has become a promising alternative for individuals who wish to end their lives. Yet, little is known about this from the perspective of those who engage in the phenomenon. METHODS: This study applied the qualitative research approach, following the grounded theory tradition. It includes 11 in-depth semi-structured interviews with Israeli members of the Swiss non-profit Dignitas who contemplated traveling to Switzerland for aid-in-dying. RESULTS: Seven themes emerged from the data analysis, including health and functioning; feelings regarding survivorship and existence; interacting with the health sector; attitudes regarding death and dying; suicide; choosing death; and choosing suicide tourism. A significant portion of the participants had experienced suicidal thoughts and had even previously attempted suicide, some more than once. Most of them referred to chronic illnesses, functional disability, and social isolation. They understand suffering within the subjective dimension, namely only by the person who is actually subjected to the disease, ailments, and disability. Participants regarded aid-in-dying in Switzerland as positive thanks to its guaranteed outcome: "beautiful death", compared to "disadvantaged dying" which places a burden on the participants' loved ones throughout the prolonged dying. Most of them do not necessarily want to have their loved ones beside them when they die, and they see no significant meaning in dying in a foreign country to which they have no emotional or civil attachment. CONCLUSION: The desirable approval or tragic refusal by Dignitas to participants' requests for suicide tourism enhances the paradox between the perception of aid-in-dying as a mechanism for fulfilling controlled death and its bureaucratic and materialistic characteristics specifically reflected in a paid, formalized approach to aid-in-dying that cultivate dependency and collaboration.
