Optimizing Colorectal Cancer Care in Older Patients

Colorectal cancer is a disease affecting mainly older people, a fact that is becoming more apparent with the global population aging. However, this patient group is more likely to be subjected to suboptimal treatment due to a number of factors, but most commonly as a result of the physician’s weakness to recognize those fit for the full spectrum of cancer therapy. In this regard, clinical screening tests, such as the Comprehensive Geriatric Assessment, can be invaluable in guiding treatment decisions. Fluoropyrimidine-based adjuvant chemotherapy clearly confers a survival advantage in older individuals with node-positive disease; however, the benefit from the administration of oxaliplatin-based regimens is less clear. Palliative chemotherapy also has an important role in managing metastatic disease, and with the use of novel targeted agents it can potentially prolong survival and improve quality of life. The management of rectal cancer in this population can present a challenge, since it appears that the optimal treatment of chemoradiation followed by total mesorectal excision can be applied in select few. Indeed, the morbidity and mortality rates in older people treated with these combined modalities can be too high, guiding many physicians to opt for more conservative approaches, directed at providing palliation and local control, especially in those with limited life expectancy. In conclusion, in order to provide the best care in an older colorectal cancer patient, we need to individualize our approach, selecting the right patient for the right treatment.     

Transthoracic Repair of Asymptomatic Morgagni Hernia in an Adult

Morgagni hernia represents a rare type of diaphragmatic hernia which usually occurs on the right side, in the anterior mediastinum. Predisposing factors of Morgagni hernia include pregnancy, obesity or other causes of increased intraabdominal pressure, and a history of trauma. Most of adults diagnosed with a foramen of Morgagni are asymptomatic. We report a case of an overweight 23-year-old asymptomatic patient with a Morgagni hernia incidentally diagnosed on chest x-ray. There was a satisfactory result after the repair by a transthoracic approach.     

Laparoscopic versus open appendectomy： Which way to go？

AIM： To compare the outcome of laparoscopic versus open appendectomy. METHODS： Prospectively collected data from 293 consecutive patients with acute appendicitis were studied. These comprised of 165 patients who underwent conventional appendectomy and 128 patients treated laparoscopically. The two groups were compared with respect to operative time, length of hospital stay, postoperative pain, complication rate and cost. RESULTS： There were no statistical differences regarding patient characteristics between the two groups. Conversion to laparotomy was necessary in 2 patients （1.5%）. Laparoscopic appendectomy was associated with a shorter hospital stay （2.2 d vs 3.1 d, P = 0.04）, and lower incidence of wound infection （5.3% vs 12.8%, P = 0.03）. However, in patients with complicated disease, intra-abdominal abscess formation was more common after laparoscopic appendectomy （5.3% vs 2.1%, P = 0.002）. The operative time and analgesia requirements were similar in the two groups. The cost of treatment was higher by 370 in the laparoscopic group. CONCLUSION： Laparoscopic appendectomy is as safe and efficient as open appendectomy, provided surgical experience and equipment are available.     

Total fluid intake of children and adolescents: cross-sectional surveys in 13 countries worldwide

Purpose

To describe total fluid intake (TFI) according to socio-demographic characteristics in children and adolescents worldwide.

Methods

Data of 3611 children (4–9 years) and 8109 adolescents (10–18 years) were retrieved from 13 cross-sectional surveys (47 % males). In three countries, school classes were randomly recruited with stratified cluster sampling design. In the other countries, participants were randomly recruited based on a quota method. TFI (drinking water and beverages of all kinds) was obtained with a fluid-specific record over 7 consecutive days. Adequacy was assessed by comparing TFI to 80 % of adequate intake (AI) for total water intake set by European Food Safety Authority. Data on height, weight and socio-economic level were collected in most countries.

Results

The mean (SD) TFI ranged from [1.32 (0.68)] to [1.35 (0.71)] L/day. Non-adherence to AIs for fluids ranged from 10 % (Uruguay) to >90 % (Belgium). Females were more likely to meet the AIs for fluids than males (4–9 years: 28 %, OR 0.72, p = 0.002; 10–18 years: 20 %, OR 0.80, p = 0.001), while adolescents were less likely to meet the AI than children (OR 1.645, p < 0.001 in males and OR 1.625, p < 0.001 in females).

Conclusions

A high proportion of children and adolescents are at risk of an inadequate fluid intake. This risk is especially high in males and adolescents when compared with females or children categories. This highlights water intake among young populations as an issue of global concern.

     

The associations between physical activity, inflammation, and coagulation markers, in people with metabolic syndrome: the ATTICA study.

OBJECTIVE: Metabolic syndrome is a condition that promotes atherosclerosis and increases the risk of cardiovascular mortality and morbidity. We evaluated whether leisure time physical activity is associated with the levels of inflammatory and coagulation markers, in people with metabolic syndrome. METHODS: From May 2001 to December 2002 we randomly enrolled 1514 men and 1528 women (>18 years old), without any clinical evidence of cardiovascular disease, stratified by age-gender (census 2001). The population of the study was divided into those who fulfilled the NCEP ATP III criteria for the metabolic syndrome (n=701 or 33% men and 13% women) and the rest of the participants (n=2341). We assessed the relationship between self-reported physical activity status and inflammatory, and coagulation markers [i.e., C-reactive protein (CRP), serum amyloid-A (SAA), interleukin (IL)-6, tumour necrosis factor (TNF)-alpha, white blood cell (WBC) counts, and fibrinogen (FIB)], after taking into account the effect of several confounders. RESULTS: Of the non-metabolic syndrome group, 56% of men and 58% of women were classified as sedentary, while of the metabolic syndrome group 58% men and 72% women were sedentary. After controlling for various potential confounders we found that physically active individuals with the metabolic syndrome had 36% lower levels of CRP, 15% lower levels of WBC, 19% lower levels of SAA, 15% lower levels of TNF-alpha, 30% lower levels of IL-6 and 15% lower levels of FIB, compared to sedentary (all P<0.05). Similar results were observed in the non-metabolic syndrome group. CONCLUSIONS: The adoption of a physically active lifestyle is independently associated with lower levels of the investigated biomarkers in individuals with the metabolic syndrome. The latter may suggest a pathway for reducing cardiovascular events, even in high-risk people.
