Conjugated linoleic acids (CLA) were identified in 1980's, since then it has been intensively studied due to its various beneficial health effects such as anti-inflammatory, anti-atherogenic, anti-carcinogenic and anti-diabetic/obesity effects. Isomer specificity of a number of CLA isomers, especially predominant isomer 9Z,11E- and 10E,12Z-CLA, is now recognized. However, the less prevalent CLA isomers have not been well characterized. Recently, studies have reported the distinctively different effects of 9E,11E-CLA in colon cancer cells, endothelial cells, and macrophage cells compared to the rest of CLA isomers. In this review, various effects of CLAs, especially anti-inflammatory and anti-atherogenic effects, will be discussed with focusing on the isomer-specific effects and potential mechanism of action of CLA. At last, recent studies about 9E,11E-CLA in in vitro and animal models will be discussed.

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) is a relatively safe procedure; however, no study has evaluated the safety of PEG tube placement in patients over the age of 100 years. METHODS: We conducted a retrospective review of patient records for patients who underwent PEG tube placement. Thirty patients aged 100 years and older were identified and a random sample of 275 patients was selected for comparison. RESULTS: The mean age of the patients was 80.6±16.2 years. No procedure-related deaths or major complications were identified; the overall inpatient mortality rate was 7.6%. Minor complications were noted in 4% (n=12) of the patients. Centenarian patients were predominantly female (80% [n=24] vs. 54% [n=147], p=0.006), with a mean age of 100.5±0.9 years. There was no significant difference in procedural success rates (93.3% vs. 97.4%, p=0.222) or inpatient mortality (6.7% [n=2] vs. 7.7% [n=21], p=1.000) between the two groups. However, a higher minor complication rate was noted in the older patients (13.3% [n=4] vs. 2.9% [n=8], p=0.022). CONCLUSIONS: Success rates, major complications and inpatient mortality associated with PEG tubes in patients aged over 100 years are comparable to those observed in relatively younger patients at our center; however minor complication rates are relatively higher. These findings lead us to believe that PEG tubes may be safely attempted in carefully selected patients in this subset of the population.

The survival rate of cancer is increasing as treatment improves. As patients with cancer now live longer, impairments may arise that impact quality of life (QOL) and function. Therefore, a focus on QOL is often as important as survival. An interdisciplinary team can achieve goal-oriented and patient-centered rehabilitation, which can optimize function and QOL, and minimize impairments, restrictions, and activity limitations. In most cases, cancer patients must be active participants in therapy and exhibit carryover. Patients with cancer often have impairments that include fatigue, pain, brain fog, impaired cognition, paresis, mood disorders, difficulty with activities of daily living (ADL), bowel/bladder/sexual dysfunction, and bone and soft tissue involvement. Adaptive equipment, exercise, and ADL training can mitigate restrictions on activity. The trajectory and phase of the disease along the continuum of cancer care may influence the goals of rehabilitation in that time window. QOL is often influenced by participation in vocational, recreational, and home-based activities. A holistic perspective should include an analysis of distress, socioeconomic barriers, and transportation limitations when addressing issues.

The recurrent laryngeal nerve is a bilateral branch of the vagus nerve that is mainly associated with the motor innervation of the intrinsic muscles of the larynx. Despite its bilateral distribution, the right and left recurrent laryngeal nerves display unequal length due to embryological processes related to the development of the aortic arches. This length asymmetry leads to theories about morphological compensations to provide symmetrical functions to the intrinsic muscles of the larynx. In this study we investigated the developmental and cross-sectional morphometrics of the recurrent laryngeal nerves in human fetuses. Fifteen stillbirth fetuses donated to anatomical and medical research were used for investigation.Fetuses had intrauterine age ranging from 30 to 40 weeks estimated by biometry methods. Specialized anatomical dissection of the visceral block of the neck was performed to prepare histological samples of the recurrent laryngeal nerves in its point of contact with the larynx, and morpho-quantitative techniques were applied to evaluate the epineurium and perineural space of the recurrent laryngeal nerves. No statistical difference in the cross-sectional morphology of the epineurium and perineural space between right and left recurrent laryngeal nerves intra-individually was confirmed, however, we found evidence that these structures are under greater development in the left recurrent laryngeal nerve during 30 to 40 weeks of intrauterine life. Our data suggest that the nerves are under morphological development that possibly set the stage for accommodation of larger diameter and myelinization of the left recurrent laryngeal nerve during post-natal life.

STUDY DESIGN: This was a prospective randomized comparative study. PURPOSE: The aim of this study was to objectify donor site-related pain following anterior iliac crest graft harvesting, in patients who have undergone multilevel anterior cervical discectomy and fusion with plating (ACDFP); and to assess the effect of an intraoperative local single injection of ropivacaine on postoperative pain. OVERVIEW OF LITERATURE: Multilevel ACDFP can be associated with a high non-union rate. Autogenous iliac bone has been used to increase union rates, although a high incidence of donor site-related pain has been reported. METHODS: Forty consecutive patients who required 3-level or 4-level ACDFP were prospectively assessed for donor site-related pain. Pain levels were assessed daily for five days postoperative using the visual analog scale (VAS). Patients were randomly assigned to group A or B. In group A patients, 7-10 mL of ropivacaine (0.2%) was injected into the iliac crest after iliac crest graft harvesting. Morphine usage via patient controlled analgesia was calculated. At six months postoperative, patient complaints at the harvest site were documented. RESULTS: Patients were randomly assigned to group A or B. In group A, ropivacaine was locally administered at the site of the iliac crest graft harvest after fascia closure. In group B, no additional treatments were administered. The average patient age in group A was 56+/-7.6 years, whereas the average age of patients in group B was 52.6+/-10.4 years. Group A had an average of 0.6+/-0.7 previous surgeries per patient, whereas group B had an average of 0.8+/-1.0 previous surgeries per patient. The average number of levels fused in group A was 3.6+/-0.7, whereas the average number of levels fused in group B was 3.7+/-0.9 (all p>0.05). In group A, the mean ropivacaine volume administered was 8.4+/-1.5 mL. No patient complaints regarding chronic pain, were reported six months postoperatively. No complications were encountered from the harvest site, and all patients underwent successful 3-level and 4-level ACDFP. Statistical analysis showed significant differences for VAS on postoperative day 1 (p=0.004) and day 2 (p=0.005). CONCLUSIONS: VAS assessment showed overall moderate perioperative morbidity in terms of donor site-related pain, which was reduced by administering ropivacaine.

BACKGROUND/AIMS: Literature on the safety of endoscopic retrograde cholangiopancreatography (ERCP) in elderly patients is divided. Based on this we decided to examine the safety of ERCP in nonagenarian patients. METHODS: A total of 1,389 patients, with a mean age of 63.94±19.62 years, underwent ERCP during the study period. There were 74 patients aged 90 years or older with a mean age of 92.07±1.8. Logistic regression showed that nonagenarian patients had a significantly increased odds of in-patient mortality (adjusted odds ratio [AOR]=9.6; 95% confidence interval [CI]=4, 23; p≤0.001). Charlson Comorbidity Index (CCI) ≥2 was also an independent predictor of in-patient mortality (AOR=2.4; 95% CI=1.2, 5.2; p=0.021). Age ≥90 was not associated with increased adverse events; however emergency procedures (AOR=2.4; 95% CI=1.5, 4; p < 0.001) and CCI ≥2 (AOR=2.6; 95% CI=1.7, 4.0; p < 0.001) were more likely to have adverse events. CONCLUSIONS: Age ≥90 and CCI ≥2 are independently associated with increased odds of in-patient mortality in patients undergoing ERCP, whereas emergency procedures and CCI ≥2 are associated with an increased adverse event rate. Caution must be exercised when considering ERCP in patients aged ≥90 years and those with a CCI ≥2.
