Eradicating an invasive mammal requires local elimination and reduced reinvasion from an urban source population.

Invasive mammal eradications are increasingly attempted across large, complex landscapes. Sequentially controlled management zones can be at risk of reinvasion from adjacent uncontrolled areas, and managers must weigh the relative benefits of ensuring complete elimination from a zone or minimizing reinvasion risk. This is complicated in urban areas, where habitat heterogeneity and a lack of baseline ecological knowledge increase uncertainty. We applied a spatial agent-based model to predict the reinvasion of a well-studied species, the brushtail possum (Trichosurus vulpecula), across an urban area onto a peninsula that is the site of an elimination campaign in Aotearoa New Zealand. We represented fine-scale urban habitat heterogeneity in a land cover layer and tested management scenarios that varied four factors: the density of possums remaining following an elimination attempt, the maintenance trap density on the peninsula, and effort expended toward preventing reinvasion by means of a high-density trap buffer at the peninsula isthmus or control of the source population adjacent to the peninsula. We found that achieving complete elimination on the peninsula was crucial to avoid rapid repopulation. The urban isthmus was predicted to act as a landscape barrier and restrict immigration onto the peninsula, but reliance on this barrier alone would fail to prevent repopulation. In combination, complete elimination, buffer zone, and source population control could reduce the probability of possum repopulation to near zero. Our findings support urban landscape barriers as one tool for sequential invasive mammal elimination but reaffirm that novel methods to expose residual individuals to control will be necessary to secure elimination in management zones. Work to characterize the urban ecology of many invasive mammals is still needed.

International travel as a risk factor for gastrointestinal infections in residents of North East England.

International travel is thought to be a major risk factor for developing gastrointestinal (GI) illness for UK residents. Here, we present an analysis of routine laboratory and exposure surveillance data from North East (NE) England, describing the destination-specific contribution that international travel makes to the regional burden of GI infection.Laboratory reports of common notifiable enteric infections were linked to exposure data for cases reported between 1 January 2013 and 31 December 2022. Demographic characteristics of cases were described, and rates per 100,000 visits were determined using published estimates of overseas visits from the Office for National Statistics (ONS) International Passenger Survey (IPS).About 34.9% of cases reported international travel during their incubation period between 2013 and 2022, although travel-associated cases were significantly reduced (>80%) during the COVID-19 pandemic. Between 2013 and 2019, half of Shigella spp. and non-typhoidal Salmonella infections and a third of Giardia sp., Cryptosporidium spp., and Shiga toxin-producing Escherichia coli (STEC) infections were reported following travel. Rates of illness were highest in travellers returning from Africa and Asia (107.8 and 61.1 per 100,000 visits), with high rates also associated with tourist resorts like Turkey, Egypt, and the Dominican Republic (386.4-147.9 per 100,000 visits).International travel is a major risk factor for the development of GI infections. High rates of illness were reported following travel to both destinations, which are typically regarded as high-risk and common tourist resorts. This work highlights the need to better understand risks while travelling to support the implementation of guidance and control measures to reduce the burden of illness in returning travellers.

A comparison of the motor effects and analgesic efficacy following lumbar plexus block combined with sciatic nerve block or epidural in dogs undergoing tibial plateau leveling osteotomy.

OBJECTIVE: To compare motor effects and analgesic efficacy following an ultrasound-guided lateral approach to lumbar plexus blockade at L7 and sciatic nerve blockade (LPSNB) against epidural injection in dogs undergoing tibial plateau leveling osteotomy (TPLO). STUDY DESIGN: Prospective, randomized, blinded clinical trial. ANIMALS: A total of 27 healthy adult dogs undergoing unilateral TPLO surgery. METHODS: Dogs were allocated to either LPSNB (bupivacaine 2 mg kg-1, 0.75%) or epidural (morphine PF 0.1 mg kg-1 and bupivacaine 0.5 mg kg-1, 0.75%). Other aspects of clinical management were identical, including anesthetic drug protocol, area of presurgical clipping and bladder care. Time to perform the block, response to surgical stimuli, pain scores, rescue analgesia, time to stand and walk, motor score and time to first urination were recorded. One evaluator, unaware of treatment status, performed all evaluations. Student's t-test or Mann-Whitney U test was used to compare continuous variables between groups, and Fisher's exact test for categorical variables. RESULTS: Median (range) times to stand and walk were shorter for LPSNB [60 (40-120) minutes and 90 (60-150) minutes, respectively, p = 0.003] than for epidural [150 (120-240) minutes and 180 (120-360) minutes, respectively, p = 0.006]. Four dogs required rescue intraoperatively (three in epidural group, one in LPSNB group, p = 0.438). Pain scores over the 24 hour evaluation period were similar, and not significantly different, for each group. Time to spontaneous urination [LPSNB, 330 (240-360) minutes; epidural, 300 (120-1440) minutes, p = 1.0] did not differ between groups. CONCLUSIONS AND CLINICAL RELEVANCE: An ultrasound-guided lateral paravertebral approach to the lumbar plexus within the psoas compartment at L7, combined with sciatic nerve blockade, allows faster return to normal motor function, with similar pain control and impact on urination when compared with epidural in dogs after TPLO surgery.

Changing Nurse Education Meaningfully: Cross-Cultural Collaboration and Cultural Safety in Curriculum Development.

ABSTRACT: Nurse educators are called to increase diversity in the clinical and faculty workforce; promote safe, inclusive learning environments; develop curricula that provide an anti-biased view of patients and health conditions; and provide students with educational opportunities to learn from individuals with diverse backgrounds. An innovative curriculum design inclusive of Indigenous worldviews was implemented at a tribal college. It provides an exemplar that supports diverse student learning, retention, and graduation. A curriculum inclusive of experiences that promote reflective practices and cultural safety can contribute toward a diverse, inclusive nursing workforce that provides equitable care while addressing social determinants of health.

Engagement with reservation-based Head Start teachers to explore their stress and coping: A qualitative study.

BACKGROUND: Native Americans residing in remote reservation communities find strength in connection to place, culture, language, and sovereignty; they also face challenges as their communities struggle with historical and contemporary traumas that have resulted in poverty, high crime and suicide rates and drug misuse. The psychological well-being of Head Start teachers who teach and support the needs of Native American children, is overlooked. METHODS: Qualitative interviews (n = 18) and focus groups (n = 9) were conducted with Head Start teachers, supervisors, parents, and ancillary staff to identify risk and protective factors at each level of the socioecological model (individual, relationships, community, society). Using content analysis and F4 analyse software two coders identified recurring themes. RESULTS: Individually teachers are resilient, focused more on the children's well-being than their own. Family was both significant support and stressor. Community struggles with drug and alcohol misuse and homelessness were the most frequent stressors. Workplace support included their supervisors and the mentorship they provided each other. Spirituality in the form traditional cultural practices, prayer and Christen faith were important sources of support and well-being. CONCLUSIONS: This paper provides insight into the stress and coping mechanisms of reservation-based Head Start teachers, identifying ways to protect and promote their health and well-being. It is important to provide support at all levels of the socioecological model to enable these teachers to strengthen their physical and psychological health and wellbeing so that they may support the children and families of Head Start to help strengthen Native American health overall.

Feasibility, acceptability and effectiveness of a culturally informed intervention to decrease stress and promote well-being in reservation-based Native American Head Start teachers.

BACKGROUND: While benefiting from strong cultural ties to family, land and culture Native Americans residing on reservations experience psychological distress at rates 2.5 times that of the general population. Treatment utilization for psychological health in reservation-based communities is low with access to culturally appropriate care lacking. Evidence suggests that for mental health treatment, Native Americans prefer culturally informed care that respects Native perspectives on health and well-being. METHODS: To decrease stress and promote well-being in tribal Head Start teachers we adapted and implemented a culturally focused intervention within a community-based participatory research framework using mixed methods. Feasibility and acceptability of the adapted 5-session curriculum was tested in a single arm intervention study with a sample of 18 teachers on the Fort Peck Reservation. Participants completed surveys at baseline and upon completion of the intervention. Within session observations and two post-intervention focus groups (n = 8, n = 10) were conducted to elaborate and explain the quantitative results eliciting participant experience of intervention effectiveness and feasibility, acceptably and appropriateness. Implementation outcomes were assessed quantitatively using the Acceptability of Intervention, Intervention Appropriateness, and Feasibility of Intervention measures. RESULTS: Quantitively, attendance rate overall was 93% with no dropouts. Pretest/posttest surveys were analyzed using t-tests and Hedges g to measure effect size. Contrary to our hypothesis, self-perceived stress showed a small positive effect size, indicating that participants were more stressed post intervention. However, depression decreased, with tribal identity and resilience showing positive effect sizes. Content analysis for the qualitative data collected within session observations and post intervention focus groups revealed how lifetime traumas were affecting participants, providing some explanation for the increase in stress. Teachers reported that the sessions helped their psychological health and well-being, supporting feasibility of future interventions. Acceptability scored highest with a mean (SD) of 4.25 (.84) out of 5, appropriateness 4.18 (.86) and feasibility 4.06 (.96) supporting intervention to be acceptable, appropriate, and feasible. CONCLUSION: Utilizing a culturally based intervention to buffer stress and support the well-being of reservation-based teachers showed promise in helping them recognize their cultural strengths, stress, and need for ongoing support. Implementation outcomes show that intervention scale-out is feasible.

A Conceptual Framework for Group Well-Child Care: A Tool to Guide Implementation, Evaluation, and Research.

OBJECTIVE: To use scoping review methods to construct a conceptual framework based on current evidence of group well-child care to guide future practice and research. METHODS: We conducted a scoping review using Arksey and O'Malley's (2005) six stages. We used constructs from the Consolidated Framework for Implementation Research and the quadruple aim of health care improvement to guide the construction of the conceptual framework. RESULTS: The resulting conceptual framework is a synthesis of the key concepts of group well-child care, beginning with a call for a system redesign of well-child care to improve outcomes while acknowledging the theoretical antecedents structuring the rationale that supports the model. Inputs of group well-child care include health systems contexts; administration/logistics; clinical setting; group care clinic team; community/patient population; and curriculum development and training. The core components of group well-child care included structure (e.g., group size, facilitators), content (e.g., health assessments, service linkages). and process (e.g., interactive learning and community building). We found clinical outcomes in all four dimensions of the quadruple aim of healthcare. CONCLUSION: Our conceptual framework can guide model implementation and identifies several outcomes that can be used to harmonize model evaluation and research. Future research and practice can use the conceptual framework as a tool to standardize model implementation and evaluation and generate evidence to inform future healthcare policy and practice.

Contraceptive decision-making through the lens of social determinants of health among female sex workers: A qualitative descriptive study.

AIMS: The aim of the study was to examine how female sex worker's motivations, desires, intentions and behaviours towards childbearing and childbearing avoidance inform their contraceptive decision-making. We explored the influence of social determinants of health in the domains of social context (sexual partners and experiences of violence), healthcare access, economic instability on the contraceptive decision-making process. DESIGN: We conducted a qualitative descriptive study informed by Miller's Theory of Childbearing Motivations, Desires and Intentions through the lens of social determinants of health. METHODS: Participants were recruited from a parent study, EMERALD, in July-September, 2020. Data were collected from 22 female sex workers ages 18-49 using semi-structured 45 to 60-min audio-recorded interviews and transcribed verbatim. Theory guided the development of the study's interview guide and thematic analytic strategy. RESULTS: Five themes emerged related to contraceptive decision-making: Motivations (value of fatherhood), Desires (relationships with love), Intentions and Behaviours (drugs overpower everything, contraceptive strategies and having children means being a protector). Women's contraceptive decision-making often included intentions to use contraception. However, social determinants such relationships with clients and intimate partners, interpersonal violence and challenges accessing traditional health care offering contraceptive services often interfered with these intentions and influenced contraceptive behaviours. CONCLUSION: Women's contraceptive decision-making process included well-informed desires related to childbearing and contraceptive use. However, social determinants across domains of health interfered with autonomous contraceptive decision-making. More effort is needed to examine the influence of social determinants on the reproductive health of this population. IMPACT: Findings from this study build on existing research that examines social determinants impacting reproductive health among female sex workers. Existing theoretical frameworks may not fully capture the influence constrained reproductive autonomy has on contraceptive decision-making. Future studies examining interpersonal and structural barriers to contraception are warranted. PATIENT OR PUBLIC CONTRIBUTION: The parent study, EMERALD, collaborated with community service providers in the study intervention.

Resilient Adaptation Strategies: Unveiling Older Adults' Coping Dynamics Amidst the COVID-19 Pandemic.

Older adults, who are particularly vulnerable to coronavirus disease 2019 (COVID-19), exhibit less stress and greater well-being than their younger peers. However, there have been no in-depth explorations of adaptive coping strategies among this population, nor has the role of frailty status been addressed. The current study examined stress and coping in 30 U.S. older adults (mean age = 81 years, range = 68 to 95 years) amidst the COVID-19 pandemic, uncovering themes of: (1) Pandemic Stresses: stresses experienced during the pandemic centered around social isolation and concern for others' well-being; (2) Resilience: older adults proved highly adaptable, with lifetime experience as a stress buffer; and (3) Silver Linings: older adults reported positive by-products, such as reconnecting with and a renewed appreciation for life and nature. Motivation for change and change itself centered around creating value and meaning in the present, especially around social isolation. Findings challenge existing ageist stereotypes, give insight into interventional design, and highlight the importance of ensuring infrastructural and societal support.

Multicenter Clinical Evaluation of Vitek 2 Meropenem-Vaborbactam for Susceptibility Testing of Enterobacterales and Pseudomonas aeruginosa.

The carbapenem/beta-lactamase inhibitor meropenem-vaborbactam (MEV) used to treat complicated urinary tract infections and pyelonephritis in adults was approved in 2017 by the U.S. Food and Drug Administration (FDA). Here, we evaluated Vitek 2 MEV (bioMérieux, Durham, NC) compared to the reference broth microdilution (BMD) method. Of 449 Enterobacterales isolates analyzed per FDA/CLSI breakpoints, the overall performance was 98.2% essential agreement (EA), 98.7% category agreement (CA), and 0% very major errors (VME) or major errors (ME). For 438 FDA intended-for-use Enterobacterales isolates, performance was 98.2% EA, 98.6% CA, and 0% VME or ME. Evaluable EA was 81.0%, but with only 42 on-scale evaluable results. Individual species demonstrated EA and CA rates of ≥90% without any VME or ME. When evaluated using European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints, overall Vitek 2 MEV performance for Enterobacterales and Pseudomonas aeruginosa demonstrated 97.3% EA, 99.2% CA, 2.3% VME, and 0.6% ME (after error resolution: 97.3% EA, 99.4% CA, 2.2% VME, and 0.4% ME) compared to the reference BMD method. Performance for P. aeruginosa included 92.2% EA, 97.4% CA, 0% VME, and 3.0% ME (after error resolution: 92.2% EA, 98.7% CA, 0% VME, and 1.5% ME). Performance for Enterobacterales included 98.2% EA, 99.6% CA, 3.0% VME, and 0.2% ME. Evaluable EA was 80.6% but was based on only 67 evaluable results. These findings support Vitek 2 MEV as an accurate automated system for MEV susceptibility testing of Enterobacterales and P. aeruginosa and could be an alternate solution to the manual-labor-intensive reference BMD method.

Experiences of pregnant women exposed to Hurricanes Irma and Maria in the US Virgin Islands: a qualitative study.

INTRODUCTION: Hurricanes Irma and Maria made landfall in the US Virgin Islands (USVI) in 2017. To date, there is no published literature available on the experiences of pregnant women in the USVI exposed to these hurricanes. Understanding how hurricanes affect pregnant women is key to developing and executing targeted hurricane preparedness and response policies. The purpose of this study was to explore the experiences of pregnancy and birth among women in the USVI exposed to Hurricanes Irma and Maria. METHODS: We employed a qualitative descriptive methodology to guide sampling, data collection, and analysis. Semi-structured interviews of 30-60 min in length were conducted with a purposive sample of women (N = 18) in the USVI who were pregnant during or became pregnant within two months after the hurricanes. Interviews were transcribed verbatim and data managed in MAXQDA. Team members developed a codebook, applied codes for content, and reconciled discrepancies. We thematically categorized text according to a socioecological conceptual framework of risk and resilience for maternal-neonatal health following hurricane exposure. RESULTS: Women's experiences were organized into two main categories (risk and resilience). We identified the following themes related to risk at 3 socioecological levels including: (1) individual: changes in food access (We had to go without) and stress (I was supposed to be relaxing); (2) household/community: diminished psychosocial support (Everyone was dealing with their own things) and the presence of physical/environmental hazards (I was really scared); and (3) maternity system: compromised care capacity (The hospital was condemned). The themes related to resilience included: (1) individual: personal coping strategies (Being calm); (2) household/community: mutual psychosocial and tangible support (We shared our resources); and (3) the maternity system: continuity of high-quality care (On top of their game). CONCLUSIONS: A socioecological approach provides a useful framework to understand how risk and resilience influence the experience of maternal hurricane exposure. As the frequency of the most intense hurricanes is expected to increase, clinicians, governments, and health systems should work collaboratively to implement hurricane preparedness and response plans that address pregnant women's unique needs and promote optimal maternal-infant health.

Multicenter evaluation of the VITEK MS matrix-assisted laser desorption/ionization-time of flight mass spectrometry system for identification of bacteria, including Brucella, and yeasts.

The use of matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry has proven to be rapid and accurate for the majority of clinical isolates. Some gaps remain concerning rare, emerging, or highly pathogenic species, showing the need to continuously expand the databases. In this multicenter study, we evaluated the accuracy of the VITEK MS v3.2 database in identifying 1172 unique isolates compared to identification by DNA sequence analysis. A total of 93.6% of the isolates were identified to species or group/complex level. A remaining 5.2% of the isolates were identified to the genus level. Forty tests gave a result of no identification (0.9%) and 12 tests (0.3%) gave a discordant identification compared to the reference identification. VITEK MS is also the first MALDI-TOF MS system that is able to delineate the four members of the Acinetobacter baumannii complex at species level without any specific protocol or special analysis method. These findings demonstrate that the VITEK MS v3.2 database is highly accurate for the identification of bacteria and fungi encountered in the clinical laboratory as well as emerging species like Candida auris and the highly pathogenic Brucella species.

Wakȟáŋyeza (Little Holy One) - an intergenerational intervention for Native American parents and children: a protocol for a randomized controlled trial with embedded single-case experimental design.

BACKGROUND: Trauma within Native American communities compromises parents' parenting capacity; thus, increasing childrens' risk for substance use and suicide over the lifespan. The objective of this manuscript is to describe the Wakȟáŋyeza (Little Holy One) intervention and evaluation protocol, that is designed to break cycles of intergenerational trauma, suicide, and substance use among Fort Peck Assiniboine and Sioux parents and their children. METHODS: A randomized controlled trial with an embedded single-case experimental design will be used to determine effectiveness of the modular prevention intervention on parent-child outcomes and the added impact of unique cultural lesson-components. Participants include 1) Fort Peck Assiniboine and Sioux parents who have had adverse childhood experiences, and 2) their children (3-5 years). Parent-child dyads are randomized (1:1) to Little Holy One or a control group that consists of 12 lessons taught by Indigenous community health workers. Lessons were developed from elements of 1) the Common Elements Treatment Approach and Family Spirit, both evidence-based interventions, and 2) newly created cultural (intervention) and nutrition (control group only) lessons. Primary outcomes are parent (primary caregiver) trauma symptoms and stress. Secondary outcomes include: Parent depression symptoms, parenting practices, parental control, family routines, substance use, historical loss, communal mastery, tribal identity, historical trauma. Child outcomes include, externalizing and internalizing behavior and school attendance. Primary analysis will follow an intent-to-treat approach, and secondary analysis will include examination of change trajectories to determine impact of cultural lessons and exploration of overall effect moderation by age and gender of child and type of caregiver (e.g., parent, grandparent). DISCUSSION: Many Native American parents have endured adverse childhood experiences and traumas that can negatively impact capacity for positive parenting. Study results will provide insights about the potential of a culturally-based intervention to reduce parental distress - an upstream approach to reducing risk for childrens' later substance misuse and suicidality. Intervention design features, including use of community health workers, cultural grounding, and administration in Head Start settings lend potential for feasibility, acceptability, sustainability, and scalability.

Open approach to the ventral transversus abdominis plane in the dog: evaluation and injectate dispersion in cadavers.

OBJECTIVE: To evaluate a direct intra-abdominal approach to injection of the ventral transversus abdominis plane (TAP) and compare the dispersion of two volumes of injectate. STUDY DESIGN: Prospective anatomic and feasibility study. ANIMALS: A total of 10 canine cadavers weighing 9 ± 4 kg. METHODS: A ventral incision was made extending through the linea alba, from the umbilicus and extending 5 cm caudally. A single injection of an isovolumic mixture of iopamidol and new methylene blue was performed with a hypodermic needle placed within the TAP of each hemiabdomen, alternating between 0.5 mL kg-1 in low-volume group (LV) and 1 mL kg-1 in high-volume group (HV). Surgical staples marked the incision. Computed tomography and three-dimensional reconstruction of the tomographic images evaluated the dimensions, cranial and caudal spread beyond the incision and the total area of the injectate. Dissection determined the extent of nerve staining within the TAP adjacent to the abdominal incision. Wilcoxon signed rank (stain) or paired t test was used to compare variables between groups. Data are reported as mean ± standard deviation or median (range). RESULTS: Injectate spread was within the ventral TAP. Length of spread was 2.5 ± 1.6 cm greater in group HV than in group LV. There was a strong positive correlation between the surface area (p = 0.02, r = 0.71) and cranial-caudal spread of injectate (p = 0.041, r = 0.65) with volume. All but two LV injections were associated with staining of all nerves adjacent to the incision. Additional nerves caudal to the incision were stained in group HV (p = 0.02). CONCLUSIONS: This approach to the TAP was easily performed, with volume of injectate positively influencing distribution. CLINICAL RELEVANCE: This technique is easily applied and future prospective studies are warranted to determine its analgesic efficacy.

Cystic neutrophilic granulomatous mastitis: The Cleveland Clinic experience with diagnosis and management.

Granulomatous mastitis is an uncommon inflammatory disease that typically presents with painful breast lesions. Recent publications have brought to light a specific subset of granulomatous mastitis patients with a distinct histological pattern of disease termed, "cystic neutrophilic granulomatous mastitis" (CNGM). Although many cases of granulomatous lobular mastitis have been thought to be idiopathic, this rare subset of an uncommon disease has been linked to infections with Corynebacterium species. Herein, a cohort of CNGM patients from a large, tertiary care, North-American, academic medical center is presented. Correlative demographic, clinical, radiographic, pathologic, microbiologic, management, and outcomes data are provided. Collaborative communication between specialists to accurately diagnose and manage these patients is essential to decreasing potential morbidity.

A retrospective study of fecal output and postprocedure colic in 246 horses undergoing standing sedation with detomidine, or general anesthesia with or without detomidine.

OBJECTIVE: To determine time to first passage of feces, total fecal piles and incidence of colic in the first 24 hours postprocedure in horses undergoing standing sedation with detomidine, or general anesthesia with or without detomidine. STUDY DESIGN: Retrospective cohort study. ANIMALS: A total of 246 horses. METHODS: Records of all horses that underwent standing sedation or general anesthesia between December 2012 and March 2016 were reviewed. Horses aged <6 months, admitted for colic or cesarean section, with inadequate data, and those not administered xylazine and/or detomidine were excluded. Records included patient signalment, fasting duration, procedure performed, drugs administered, time to first feces, number of fecal piles during 24 hours postprocedure and mention of colic. Chi-square, Fisher's exact and Tukey's post hoc comparison tests were used. Parametric data were reported as mean ± standard deviation with significance defined as p <0.05. RESULTS: In total, 116 and 57 horses underwent general anesthesia without detomidine (group GA) and with detomidine (group GA-D), respectively, and remaining 73 horses underwent standing sedation with detomidine (group S-D). Detomidine dose was significantly higher in group S-D than in group GA-D. Time to first feces was longer (7.1 ± 4.2 hours), and group S-D horses passed one fewer fecal pile (6.3 ± 2.4) than group GA horses. There was no interaction between detomidine treatment and preprocedure food withholding and the time to first feces or the number of fecal piles in the first 24 hours postprocedure. Overall, seven horses (2.8%) showed signs of colic (five, one and one in GA, GA-D and S-D, respectively). CONCLUSIONS AND CLINICAL RELEVANCE: Detomidine administration, as part of an anesthetic protocol or for standing sedation procedures, should not be expected to contribute to postprocedural colic.

Increased Invasive Pneumococcal Disease, North East England, UK.

Since April 2014, invasive pneumococcal disease incidence has increased substantially across North East England, United Kingdom, reversing the decline that followed the 2006 introduction of pneumococcal conjugate vaccines. Significant increases occurred in 23-valent polysaccharide vaccine serotypes and nonvaccine serotypes. Trends in other regions and long-term effects of multivalent vaccines require further investigation.

Alfaxalone alone or combined with midazolam or ketamine in dogs: intubation dose and select physiologic effects.

OBJECTIVE: To determine the intubation dose and select physiologic effects of alfaxalone alone or in combination with midazolam or ketamine in dogs. STUDY DESIGN: Prospective, clinical study. ANIMALS: Fifty-three healthy client-owned dogs [mean±standard deviation (SD)] 5.1±1.8 years, 27±15.4 kg, scheduled for elective orthopedic surgery. METHODS: After premedication with acepromazine (0.02 mg kg-1) and hydromorphone (0.1 mg kg-1) intramuscularly, alfaxalone (0.25 mg kg-1) was administered intravenously over 15 seconds followed immediately by 0.9% saline (AS), midazolam (0.3 mg kg-1; AM), ketamine (1 mg kg-1; AK1), or ketamine (2 mg kg-1; AK2). Additional alfaxalone (0.25 mg kg-1 increments) was administered as required to permit endotracheal intubation. The incidence of apnea and the time from intubation until spontaneous movement were recorded. Heart rate (HR) and blood pressure were recorded 15 minutes after premedication, after intubation and 2, 5, 10 and 15 minutes thereafter. Blood was collected for measurement of serum glucose and insulin concentrations before induction, after intubation and at 2, 5, 10 and 50 minutes. Data were analyzed by split-plot anova with Bonferroni adjustment for the number of group comparisons. RESULTS: Mean±SD alfaxalone mg kg-1 doses required for endotracheal intubation were AS (1.0±0.4), AM (0.4±0.2), AK1 (0.5±0.3) and AK2 (0.5±0.4) (p=0.0005). Differences in cardiopulmonary variables among groups were minor; HR decreased in AS, while in other groups, HR increased transiently postintubation. Incidence of apnea in AS was 54% with no significant difference among groups. Midazolam significantly prolonged time from intubation until spontaneous movement (p<0.002). CONCLUSIONS AND CLINICAL RELEVANCE: Midazolam and ketamine reduced the alfaxalone dose required for endotracheal intubation. Serum glucose and insulin concentrations were not influenced by administration of alfaxalone alone or when administered with midazolam or ketamine.

Pain and analgesia following onychectomy in cats: a systematic review.

OBJECTIVES: To systematically review published studies evaluating pain associated with onychectomy in cats, and to assess the efficacy of the analgesic therapies applied. DATABASES USED: Four sources were used to identify manuscripts for review. Databases searched were those of the National Library of Medicine, EMBASE and CAB International. In addition, pertinent references in the bibliographies of included articles were retrieved. RESULTS: Twenty manuscripts published in refereed journals were reviewed. These included papers reporting 18 clinical trials and two studies conducted in conditioned research cats. Twelve analgesics were evaluated, including seven opioids, four non-steroidal anti-inflammatory drugs and one local anesthetic. Nine studies involved a direct comparison of analgesic agents. Limb use was abnormal when measured at 2 and 12 days following onychectomy, and neither fentanyl patch nor butorphanol administration resulted in normal use of the surgical limb. In another study, cats evaluated at 6 months after this surgery were not lame. Differing surgical techniques were compared in six studies; the results indicated that pain scores were lower after laser surgery than after scalpel surgery. The difficulties associated with assessing pain in cats and the lack of sensitivity of the evaluation systems utilized were highlighted in many of the studies. Huge variations in dose and dosing strategies had significant impacts on drug efficacy. Statistically significant differences among treatments were found in most studies; however, no clearly superior analgesic treatment was identified. A combination of meloxicam or robenacoxib with an opioid may provide more effective analgesia and should be evaluated.
