Raw diets for dogs and cats: Potential health benefits and threats.

Raw meat-based diets for pet nutrition are becoming increasingly popular. The percentage of meat content, composition of nutrients, and amount of additives started to play an important role in the recipe of a given food. However, the use of healthier and unprocessed food must also be balanced with the animal's specific needs based on its anatomy, physiology, and behavior. There are many potential advantages and disadvantages of a biologically appropriate raw food (BARF) diet, and all of them should be considered before switching to this approach. Raw meat is considered a diet closest to nature and least processed. However, raw diets threaten pet health because of the potential for nutrient imbalances. The choice of raw meat in pets' everyday diet should be supported by the veterinarian's medical decision and preferably also with nutritionist help. Growing animals require a specific Ca:P ratio in their diet, which may be improper in raw meat. For cats, taurine levels must be carefully checked. In addition, an imbalanced raw-meat diet can be the cause of poor semen quality in males. Females are prone to inhibition of the estrus cycle, especially due to hyperthyroidism. Exogenous thyroid hormone intake is a real concern when feeding a neck/head meat with thyroid glands. There is also a possibility of bacterial or parasitic presence in raw meat. The present paper aims to summarize the current state of knowledge about the benefits and threats of eating a raw meat diet for the health concerns of companion animals.

Prolonged P wave duration is associated with right atrial dimensions, but not atrial arrhythmias, in middle-aged endurance athletes.

BACKGROUND: Atrial arrhythmias occur at a higher than expected prevalence amongst endurance athletes. Few studies have examined both atrial structure and arrhythmias in middle-aged endurance athletes. We examined the relationship between P-wave duration, atrial dimensions, and the presence of atrial ectopy in long-standing, middle-aged endurance athletes. METHODS: Middle-aged athletes with a minimum of 10 years of competitive endurance sport history and no history of structural heart disease or clinical atrial arrhythmias, had 12-lead ECGs to assess P-wave duration, signal-averaged ECGs (SAECG) to assess filtered P-wave duration, a 24 h Holter monitor to assess atrial ectopy, and echocardiography and cardiac magnetic resonance imaging to assess atrial structural characteristics. RESULTS: Amongst endurance athletes (n = 104; mean age = 54 ±â€¯5 years; 63% male), filtered P-wave duration on SAECG was correlated with P-wave duration on 12-lead ECG (r = 0.36, p, 0.0001), as well as with larger CMR-derived RA areas (r = 0.30, p = 0.01) and volumes (r = 0.24, p < 0.05). There was no correlation between filtered P-wave duration and any LA measures on imaging (p > 0.05). There was no correlation between the incidence of atrial ectopy (premature atrial contractions or atrial tachycardia) and any electrocardiographic or structural measures. CONCLUSION: Longer filtered P-wave duration was associated with larger RA areas and volumes, without an increase in atrial ectopy.

A five-year follow-up observational study of the T-14 paediatric throat disorders outcome measure in tonsillectomy and adenotonsillectomy.

INTRODUCTION: The T-14 questionnaire is a validated outcome measurement tool to assess the value of paediatric tonsillectomy from a parent's perspective. There is a paucity of data regarding the long-term postoperative effects of tonsillectomy on quality of life in the paediatric population. Our previous study assessed T-14 scores up to year 2 postoperatively, with this study extending follow-up to 5 years. MATERIALS AND METHODS: We undertook a prospective uncontrolled observational study examining 54 paediatric patients undergoing tonsillectomy at Portsmouth Hospitals NHS Trust. Parents of children undergoing surgery were invited to complete a T-14 questionnaire preoperatively, as well as at 3 months, 6 months, 1 year, 2 years and now 5 years postoperatively. RESULTS: In total, 44 of 54 patients completed questionnaires preoperatively and at all postoperative time points, with 46 being completed at 5 years. There was a highly significant (P < 0.001) difference between the preoperative scores and all other measured T-14 scores postoperatively. The mean score preoperatively was 33.3 compared with 1.0 at 5 years. CONCLUSIONS: This is the first study to assess long-term quality of life following paediatric tonsillectomy using the T-14 questionnaire. The benefits of tonsillectomy on long-term quality of life further confirms its value within the paediatric population.

A two-year follow-up observational study of the T-14 paediatric throat disorders outcome measure in tonsillectomy and adenotonsillectomy.

INTRODUCTION: The T-14 questionnaire is a validated patient reported outcome measure used to assess the value of paediatric tonsillectomy from the patient's perspective. There are currently limited data revealing the long-term postoperative effects of tonsillectomy on quality of life in the paediatric population. A previously published study was therefore extended to provide additional data at 12 and 24 months following surgery. METHODS: A prospective uncontrolled observational study was undertaken examining 54 paediatric patients undergoing tonsillectomy at Portsmouth Hospitals NHS Trust. Parents of children having surgery were invited to complete a T-14 questionnaire preoperatively as well as at 3, 6 (previously published), 12 and 24 months postoperatively. RESULTS: The questionnaire was completed for 50 of the 54 patients preoperatively as well as at 3, 6 and 12 months postoperatively, with 44 being completed at 24 months. The mean difference between the preoperative T-14 scores and the scores at 3, 6, 12 and 24 months following surgery were highly statistically significant (p<0.001). CONCLUSIONS: This is the first study published in the literature to assess the T-14 questionnaire at 12 and 24 months following paediatric tonsillectomy, providing evidence of the ongoing benefit of patient reported outcome measures. This further confirms the value of tonsillectomy in the paediatric population and demonstrates its ongoing positive effects on quality of life.

Development, validation and initial outcomes of a questionnaire to examine human factors in postgraduate surgical objective structured clinical examinations.

BACKGROUND: Human factors including stress, repetition, burnout and fatigue are associated with possible sources of error. Objective structured clinical examinations (OSCEs), where examiners concentrate for long periods, would benefit from a human factors approach to see whether these factors affect consistency of examiner behaviour, attitude and marking. Little has been published for OSCEs, in part due to the lack of a validated tool for collecting data in this setting. METHODS: A 46-item questionnaire was developed based on the Human Factors Analysis and Classification System (HFACS) domains and completed by examiners in the Intercollegiate Membership of the Royal College of Surgeons (MRCS) examination. To refine the questionnaire, an initial analysis focused on response patterns of each item. Cronbach's α was used to assess internal consistency, and a factor analysis was performed to uncover different domains emerging from the data. RESULTS: A total of 108 examiners completed the questionnaire (90·0 per cent response rate). The questionnaire, refined to 38 items based on an initial analysis of response patterns, showed good reliability for internal consistency (Cronbach's α = 0·76) and test-retest reliability (r = 0·85, n = 48, P < 0·001). Four factors had a close themed resemblance to the original HFACS domains, but were associated with different items, suggesting that the four human-factor domains might be linked to different behaviours and attitudes in an examination setting. Analyses according to sex, professional background and experience highlighted additional stress levels in examiners from one of the surgical Royal Colleges (P <0·001), matching evidence from the situation in that College at the time of this study. CONCLUSION: The recognition and further investigation of human factors in OSCEs is needed to improve examiner experience and behaviour in order to influence delivery, candidate experience and quality assurance of these examinations.

Patient information leaflet on mastoid surgery risks: assessment of readability and patient understanding.

INTRODUCTION: It is important that patients have a good understanding of surgery-related risks, particularly for mastoid surgery, which exposes patients to the risk of very serious complications, despite addressing conditions which often have only minor symptoms. MATERIALS AND METHODS: A patient information leaflet describing the risks of mastoid surgery was prepared. However, the Hospital Patient Advice and Liaison Services team thought it was too long and complicated. It was introduced unchanged. Fifty-four consecutive mastoidectomy patients were given a questionnaire asking for their opinion of the leaflet. The leaflet was also assessed with readability formulae and the Ensuring Quality Information for Patients tool. RESULTS AND ANALYSIS: Ninety-eight per cent of respondents thought the leaflet's writing style was easy to understand. The majority (96 per cent) thought the length was 'just right'. The 7 readability formulae used established readability at a grade 9 level (i.e. appropriate for a reading age of 13-15 years). The Ensuring Quality Information for Patients score was 87.5 per cent. DISCUSSION: Despite the drive to simplify patient information leaflets, quite detailed information is sometimes required. A style which is too simple may be perceived as patronising and may encourage patients to underestimate potential risks. It is important to ask patients their opinion.

Application of the Paediatric Throat Disorders Outcome Test (T-14) for tonsillectomy and adenotonsillectomy.

INTRODUCTION: The T-14 questionnaire is a validated patient reported outcome measure (PROM) used to assess the value of paediatric tonsillectomy from the patient's perspective. Tonsillectomy is a procedure under threat. As such, this study aimed to provide further evidence supporting the role of tonsillectomy in the management of recurrent tonsillitis and obstructive sleep apnoea. METHODS: A prospective uncontrolled observational study was undertaken examining 54 paediatric patients undergoing tonsillectomy at our institution. Parents of children having surgery were invited to complete a T-14 questionnaire preoperatively as well as at three and six months postoperatively. RESULTS: The questionnaire was completed for 52 of the 54 patients preoperatively as well as at 3 and 6 months postoperatively (96% response rate). The mean difference between the preoperative and six-month T-14 score was 31.8 (p<0.0001). T-14 scores at three months were also significantly improved compared with those taken preoperatively (mean difference: 29.9, p<0.0001). CONCLUSIONS: This is the first study in the literature to assess T-14 questionnaires at three and six months following paediatric tonsillectomy, providing evidence of the early benefit on PROMs. Tonsillectomy is the most common surgical procedure performed in the UK, and it is regarded highly by patients and otolaryngologists alike. This study provides significant evidence that tonsillectomy improves PROMs, thereby demonstrating its ongoing clinical value as a funded National Health Service procedure.

The sodium pertechnetate Tc 99m scan: an aid in the evaluation of gastrointestinal bleeding.

Twenty pediatric patients presenting primarily with unexplained gastrointestinal bleeding were evaluated with sodium pertechnetate Tc 99m imaging. Three patients had normal barium enemas and scans consistent with Meckel's diverticulum. These three patients and three additional patients with normal scans underwent surgical exploration. Meckel's diverticula containing gastric mucosa were found in all three patients with positive scans. No diverticula were found in the three patients with normal scans. Four other patients had scans that were considered abnormal but not felt to represent Meckel's diverticula. In one of these patients a radiographic gastrointestinent, a nonspecific terminal ilial ulcer without gastric mucosa was found at surgery. The two other patients had normal radiographic gastrointestinal studies and no further evaluation was carried out. The etiology of gastrointestinal bleeding in pediatric patients is frequently unexplained even after thorough evaluation including celiotomy. The sodium pertechnetate Tc 99m scan is a safe, simple, non-invasive procedure that can demonstrate Meckel's diverticula with greater certainty than the barium enema and can suggest suspicious areas that can then be evaluated by more definitive procedures.
