Survey of Integrative Veterinary Medicine Training in AVMA-Accredited Veterinary Colleges.

A survey approved by the Association of American Veterinary Medical Colleges was sent to the academic deans of all 49 accredited veterinary colleges to obtain information on educational programs offered in integrative veterinary medicine (IVM). Results were compared to a previous survey with a similar design performed 7 years earlier. Survey responses were received from 43 of 49 institutions (87.8%). Thirteen respondents (30.2%) reported offering a formal course in IVM, 33 (76.7%) offered some level of instruction in the curriculum, and 32 (74.4%) provided clinical services in IVM. The most common IVM topics covered in the curriculum were rehabilitation and acupuncture. Dedicated courses in IVM had decreased since the previous survey, although faculty trained in at least one aspect of IVM increased. Clinical services incorporating IVM were present in the majority of veterinary teaching hospitals. Further investigation is required to determine the effectiveness of current IVM training in preparing veterinary graduates to discuss or utilize IVM in practice.

Canine and Feline Patients Referred Exclusively for Acupuncture and Herbs: A Two-Year Retrospective Analysis.

Acupuncture and the administration of herbal supplements are increasingly used in veterinary practice, but no retrospective studies have examined patient characteristics and treatment interventions in a population of dogs and cats presenting exclusively for such therapies. This two-year retrospective analysis of 161 referrals to an integrative medicine service at an academic teaching hospital found that dogs were more frequently treated than cats (91.9% vs. 8.1%, respectively) and that small animal patients most frequently were presented for musculoskeletal (26.7%), neurologic (16.8%), oncologic (14.9%), and dermatologic (10.6%) conditions. Cats were older than treated dogs (12.7 ± 3.7 vs. 9.5 ± 4.3 years) and more likely to be treated for oncologic complaints (odds ratio = 5.6). Patients received acupuncture (95.4%), herbal supplements (76.4%), acupuncture with percutaneous electrical nerve stimulation (electroacupuncture, 26.1%), and/or cyanocobalamin injections in acupuncture points (pharmacopuncture, 23.6%). Some differences were detected between treatment groups. This retrospective analysis provides a foundation for designing future prospective studies using acupuncture and herbs in dogs and cats.

Horses Referred to a Teaching Hospital Exclusively for Acupuncture and Herbs: A Three-Year Retrospective Analysis.

Equine acupuncture and herbal medicine are increasingly popular and have been anecdotally used in the treatment of a number of conditions. There is, however, a lack of data on the most commonly treated conditions in horses. The medical records of 164 horses presented exclusively for acupuncture and herbal therapy over a three-year period from October 2012 to October 2015 were evaluated from a mixed animal integrative medicine service at a veterinary academic teaching hospital. Horses were presented primarily for musculoskeletal conditions (62.0%), gastrointestinal disorders (9.5%), and anhydrosis (6.1%). Nearly half of all treated horses were geldings, and the mean age of treatment was 10.7 ± 6.5 years. The most common breeds were Warmbloods (28.2%), Quarter horses (20.2%), Thoroughbreds (17.8%), and Arabians (8.0%). Treatments included acupuncture (90.2%), herbal supplements (79.8%), electroacupuncture (69.9%), B12 injections (pharmacoacupuncture, 29.4%), or administration of autologous blood at acupuncture points (hemoacupuncture, 8.0%). Thirty-eight (38) different herbal formulas were recommended during the study period. Horses that were not provided herbal recommendations were more likely to present with gastrointestinal complaints (odds ratio = 11.2). Sex, breed, and presenting complaint had no or minimal impact on the types of treatments performed during the visit. However, data regarding patient characteristics and presenting complaints provide novel information which can be used to design prospective clinical trials.

A Retrospective Analysis of 5,195 Patient Treatment Sessions in an Integrative Veterinary Medicine Service: Patient Characteristics, Presenting Complaints, and Therapeutic Interventions.

Integrative veterinary medicine, the combination of complementary and alternative therapies with conventional care, is increasingly prevalent in veterinary practice and a focus of clinical instruction in many academic teaching institutions. However, the presenting complaints, therapeutic modalities, and patient population in an integrative medicine service have not been described. A retrospective analysis of 5,195 integrative patient treatment sessions in a veterinary academic teaching hospital demonstrated that patients most commonly received a combination of therapeutic modalities (39% of all treatment sessions). The 274 patients receiving multiple modalities were most frequently treated for neurologic and orthopedic disease (50.7% versus 49.6% of all presenting complaints, resp.). Older neutered or spayed dogs (mean age = 9.0 years) and Dachshunds were treated more often than expected based on general population statistics. Acupuncture, laser therapy, electroacupuncture, and hydrotherapy were frequently administered (>50% patients). Neurologic patients were more likely to receive acupuncture, electroacupuncture, and therapeutic exercises but less likely than orthopedic patients to receive laser, hydrotherapy, or therapeutic ultrasound treatments (P < 0.05). The results suggest that the application of these specific modalities to orthopedic and neurologic diseases should be subjected to increased evidence-based investigations. A review of current knowledge in core areas is presented.

Neuroprotective effects of berry fruits on neurodegenerative diseases.

Recent clinical research has demonstrated that berry fruits can prevent age-related neurodegenerative diseases and improve motor and cognitive functions. The berry fruits are also capable of modulating signaling pathways involved in inflammation, cell survival, neurotransmission and enhancing neuroplasticity. The neuroprotective effects of berry fruits on neurodegenerative diseases are related to phytochemicals such as anthocyanin, caffeic acid, catechin, quercetin, kaempferol and tannin. In this review, we made an attempt to clearly describe the beneficial effects of various types of berries as promising neuroprotective agents.

Omega-3 Fatty acids could alleviate the risks of traumatic brain injury - a mini review.

Traumatic brain injury (TBI) is an acquired brain trauma that occurs when any sudden trauma/injury causes damage to the brain. TBI is characterized by tissue damage and imbalance in the cerebral blood flow and metabolism. It has been established through laboratory experiments that the dietary supplementation of omega-3 fatty acids (FAs) could reduce the oxidative stress developed in brain due to TBI. The inclusion of omega-3 FA in diet could normalize the levels of brain-derived neurotrophic factor (BDNF), and thus, it could restore the survival of neuronal cells. BDNF improves the synaptic transmission by regulating synapsin 1 and cyclic adenosine monophosphate (cAMP) response element binding protein. The brain tissue analysis of TBI models supplemented with omega-3 polyunsaturated fatty acids (PUFAs) showed significantly reduced lipid peroxidation, nucleic acid and protein oxidation, thereby promoting neuronal and glial cell survival. Thus, omega-3 FA intake could be considered as a therapeutic option to reduce the secondary neuronal damages initiated by TBI.

Mangiferin attenuates MPTP induced dopaminergic neurodegeneration and improves motor impairment, redox balance and Bcl-2/Bax expression in experimental Parkinson's disease mice.

Mangiferin, a polyphenol compound of C-glucoside, is well-known for its anti-inflammatory, antioxidant, anticancer, antidiabetic and cognitive enhancement properties. In this study, we investigated the neuroprotective effect of mangiferin against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of Parkinson's disease (PD), which is most popular and widely used to evaluate therapeutic implications of new protective agents. Male C57BL/6 mice were orally treated with mangiferin (10, 20 and 40 mg/kg body wt.) for 14 days and from 10th day onwards MPTP (30 mg/kg, i.p.) was injected for last 5 days. MPTP treatment leads to enhanced oxidative stress, induction of apoptosis (upregulates the expression of Bax, proapoptotic protein and downregulates the expression of anti-apoptotic marker Bcl-2), and loss of dopominergic neurons which results in motor impairments. Results of our study confirmed that mangiferin prevented MPTP-induced behavioral deficits, oxidative stress, apoptosis, dopaminergic neuronal degeneration and dopamine depletion. Taken together, we conclude that mangiferin attenuates the dopaminergic neurodegeneration mainly through its potent antioxidant and antiapoptotic properties.

Effect of extenders on sperm mitochondrial membrane, plasma membrane and sperm kinetics during liquid storage of canine semen at 5°C.

The objective of this study was to evaluate the effect of addition of egg yolk (EY) or soy lecithin (SL) based extenders on dog sperm parameters during 10days storage at 5°C. Four ejaculates of pooled semen from three Mongrel dogs were divided into three aliquots and extended to a final concentration of 200 million sperm/mL using following non-commercial extenders: egg yolk extender (EYE) group - semen+20% Tris-EYE; soy lecithin (SL) group 1 - semen+SL extender with 0.04% SL; SL group 2 - semen+SL extender 0.4% SL. The extended semen samples were stored at 5°C and were evaluated for sperm mitochondrial membrane potential (MMP), plasma membrane integrity (%PMI) and computer assisted sperm analyzer (CASA) sperm motility parameters on days 0, 1, 2, 3, 4, 7 and 10. The extender, days of storage and extender×days of storage affected the MMP, %PMI and CASA sperm motility parameters (P<0.05). The addition of 0.4% SL extender reduced the speed of deterioration of sperm parameters evaluated in this study compared to EY and 0.04% SL extenders (P<0.05). In conclusion, the addition of 0.4% SL extender enhanced sperm preservation based on the variables evaluated in the present study compared to EYE and 0.04% SL extenders and plausibly preserves sperm quality longer.

Survey of colleges and schools of veterinary medicine regarding education in complementary and alternative veterinary medicine.

OBJECTIVE: To obtain information on educational programs offered in complementary and alternative veterinary medicine (CAVM) among AVMA Council on Education (COE)-accredited colleges and schools of veterinary medicine. DESIGN: Survey. SAMPLE: 41 COE-accredited colleges and schools of veterinary medicine. PROCEDURE: A questionnaire was e-mailed to academic deans at all COE-accredited colleges and schools of veterinary medicine. RESULTS: Responses were received from 34 of 41 schools: 26 in the United States, 2 in Canada, 3 in Australia and New Zealand, and 3 in Europe. Sixteen schools indicated that they offered a CAVM course. Nutritional therapy, acupuncture, and rehabilitation or physical therapy were topics most commonly included in the curriculum. One school required a course in CAVM; all other courses were elective, most of which were 1 to 2 credit hours. Courses were usually a combination of lecture and laboratory; 2 were lecture only, and 1 was laboratory only. Of the 18 schools that reported no courses in CAVM, many addressed some CAVM topics in other courses and 4 indicated plans to offer some type of CAVM course within the next 5 years. CONCLUSIONS AND CLINICAL RELEVANCE: The consensus among survey respondents was that CAVM is an important topic that should be addressed in veterinary medical education, but opinions varied as to the appropriate framework. The most common comment reflected strong opinions that inclusion of CAVM in veterinary medical curricula must be evidence-based. Respondents indicated that students should be aware of CAVM modalities because of strong public interest in CAVM and because practitioners should be able to address client questions from a position of knowledge.

Fulbright scholar international teaching and research opportunities for veterinary faculty.

The Fulbright program was established by the US Congress to "enable the government of the United States to increase mutual understanding between the people of the United States and the people of other countries." The Core Fulbright Scholar Program sends more than 800 US faculty and administrators to 125 countries to lecture or conduct research around the world each year. Unfortunately, only 28 faculty members from the US veterinary colleges have used Fulbright Scholar opportunities in the last 20 years (1989-2009). Considering recent worldwide events, such as the global dispersion of the Asian strain of highly pathogenic avian influenza and pandemic H1N1 2009 affecting human and animal species, the importance of awareness and education of veterinarians to such global issues is obviously urgent. Therefore, Fulbright scholarships represent an important opportunity to gain experience and bring this time-critical information back to fellow faculty and students. Veterinarians who wish to contribute to internationalization of the curricula and their campuses should consider applying for Fulbright Scholar support to launch their career in this pivotal direction.

Transforming growth factor beta (TGFbeta1, TGFbeta2 and TGFbeta3) null-mutant phenotypes in embryonic gonadal development.

The role transforming growth factor beta (TGFb) isoforms TGFb1, TGFb2 and TGFb3 have in the regulation of embryonic gonadal development was investigated with the use of null-mutant (i.e. knockout) mice for each of the TGFb isoforms. Late embryonic gonadal development was investigated because homozygote TGFb null-mutant mice generally die around birth, with some embryonic loss as well. In the testis, the TGFb1 null-mutant mice had a decrease in the number of germ cells at birth, postnatal day 0 (P0). In the testis, the TGFb2 null-mutant mice had a decrease in the number of seminiferous cords at embryonic day 15 (E15). In the ovary, the TGFb2 null-mutant mice had an increase in the number of germ cells at P0. TGFb isoforms appear to have a role in gonadal development, but interactions between the isoforms is speculated to compensate in the different TGFb isoform null-mutant mice.

Transgenerational effect of the endocrine disruptor vinclozolin on male spermatogenesis.

The current study was designed to examine the actions of a model endocrine disruptor on embryonic testis development and male fertility. Pregnant rats (F0) that received a transient embryonic exposure to an environmental endocrine disruptor, vinclozolin, had male offspring (F1) with reduced spermatogenic capacity. The reduced spermatogenetic capacity observed in the F1 male offspring was transmitted to the subsequent generations (F2-F4). The administration of vinclozolin, an androgen receptor antagonist, at 100 mg/kg/day from embryonic day 8-14 (E8-E14) of pregnancy to only the F0 dam resulted in a transgenerational phenotype in the subsequent male offspring in the F1-F4 generations. The litter size and male/female sex ratios were similar in controls and the vinclozolin generations. The average testes/body weight index of the postnatal day 60 (P60) males was not significantly different in the vinclozolin-treated generations compared to the controls. However, the testicular spermatid number, as well as the epididymal sperm number and motility, were significantly reduced in the vinclozolin generations compared to the control animals. Postnatal day 20 (P20) testis from the vinclozolin F2 generation had no morphological abnormalities, but did have an increase in spermatogenic cell apoptosis. Although the P60 testis morphology was predominantly normal, the germ cell apoptosis was significantly increased in the testes cross sections of animals from the vinclozolin generations. The increase in apoptosis was stage-specific in the testis, with tubules at stages IX-XIV having the highest increase in apoptotic germ cells. The tubules at stages I-V also had an increase in apoptotic germ cells compared to the control samples, but tubules at stages VI-VIII had no increase in apoptotic germ cells. An outcross of a vinclozolin generation male with a wild-type female demonstrated that the reduced spermatogenic cell phenotype was transmitted through the male germ line. An outcross with a vinclozolin generation female with a wild-type male had no phenotype. A similar phenotype was observed in outbred Sprague Dawley and inbred Fisher rat strains. Observations demonstrate that a transient exposure at the time of male sex determination to the antiandrogenic endocrine disruptor vinclozolin can induce an apparent epigenetic transgenerational phenotype with reduced spermatogenic capacity.

Internationalizing veterinary education in the 21st century.

This paper presents the results of a survey conducted in the spring of 2001 to assess international activities at colleges of veterinary medicine in North America. A questionnaire was sent to all 31 colleges of veterinary medicine in the United States and Canada, of which 22 responded. Of those schools responding to the survey, 86% have International Veterinary Medicine (IVM) programs and most have faculty involved in internationally oriented research (95%), in teaching IVM (74%), in mentoring veterinary students in IVM (84%), and in international consultancies (84%). Funding sources for faculty international activities include foundations, intramural funds, curriculum development grants, endowment/development funds, and sabbaticals. Foreign animal diseases are the most commonly taught international topic. The increasing importance of international veterinary issues is leading to the internationalization of the veterinary education in North America. Most IVM programs include activities of both faculty and students. Greater collaboration between faculty and programs across schools would allow schools to benefit from each other's strengths in IVM education.
