Health-Related Quality of Life in Patients with Hepatocellular Carcinoma Treated with Initial Transarterial Chemoembolization

Purpose

To investigate the impact of the first transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) on health-related quality of life (HRQoL) and identify predictors for low HRQoL following TACE.

Materials and Methods

HRQoL was prospectively evaluated in 79 patients with standardized questionnaires (QlQ-C30 and HCC18) pre- and 2 weeks post-TACE. Treatment response was evaluated using common tumour response criteria. Clinical parameters [e.g. Eastern Cooperative Oncology Group (ECOG) performance status, Model of End Stage Liver Disease (MELD) score], tumour load and pre-TACE HRQoL scores were tested for predicting HRQoL after TACE.

Results

Patients showed a 12.1% decrease in global health score (GHS). Major decreases were observed for physical (?21.4%), role (?23.4%), and social (?21.5%) functioning and increases in symptom severity for fatigue (+30.1%), loss of appetite (+25.3%), pain (+19.4%) after TACE. ECOG performance status >1 was associated with increased nausea/vomiting (p = 0.002) and decreased GHS (p = 0.01). MELD score >10 was associated with increased fatigue (p = 0.021) and abdominal swelling (p < 0.001). Our study showed an increase in symptom severity in patients with no symptoms before TACE for pain (p = 0.005) and abdominal swelling (p < 0.001).

Conclusion

The first TACE for treatment of HCC does not result in a major loss of HRQoL in general. For TACE as a palliative therapy maintaining HRQoL is of critical importance and standardized HRQoL assessment can help to detect HRQoL problems.

     

Dyslipidemia and atherosclerosis induced by chronic intermittent hypoxia are attenuated by deficiency of stearoyl coenzyme A desaturase

Obstructive sleep apnea leads to chronic intermittent hypoxia (CIH) and is associated with atherosclerosis. We have previously shown that C57BL/6J mice exposed to CIH and a high-cholesterol diet develop dyslipidemia, atherosclerosis of the aorta, and upregulation of a hepatic enzyme of lipoprotein secretion, stearoyl coenzyme A desaturase 1 (SCD-1). We hypothesized that (1) SCD-1 deficiency will prevent dyslipidemia and atherosclerosis during CIH; and (2) human OSA is associated with dyslipidemia and upregulation of hepatic SCD. C57BL/6J mice were exposed to CIH or normoxia for 10 weeks while being treated with either SCD-1 or control antisense oligonucleotides. Obese human subjects underwent sleep study and bariatric surgery with intraoperative liver biopsy. In mice, hypoxia increased hepatic SCD-1 and plasma very-low-density lipoprotein cholesterol levels and induced atherosclerosis lesions in the ascending aorta (the cross-section area of 156514+/-57408 microm(2)), and descending aorta (7.0+/-1.2% of the total aortic surface). In mice exposed to CIH and treated with SCD-1 antisense oligonucleotides, dyslipidemia and atherosclerosis in the ascending aorta were abolished, whereas lesions in the descending aorta showed 56% reduction. None of the mice exposed to normoxia developed atherosclerosis. In human subjects, hepatic SCD mRNA levels correlated with the degree of nocturnal hypoxemia (r=0.68, P=0.001). Patients exhibiting oxyhemoglobin desaturations at night showed higher plasma triglyceride and low-density lipoprotein cholesterol levels, compared to subjects without hypoxemia. In conclusion, CIH is associated with dyslipidemia and overexpression of hepatic SCD in both humans and mice alike; SCD-1 deficiency attenuates CIH-induced dyslipidemia and atherosclerosis in mice.     

Sexual changes in a case of gastric stapling in adolescence

This is the case of an adolescent female who developed a moderately severe depressive illness eighteen months after a gastric stapling procedure for morbid obesity. The weight loss following surgery was associated with an emergence of sexual awareness and interest, culminating in the patient's infatuation with a medical practitioner. The importance of an assessment of psychosexual development is discussed in relation to this procedure.     

Ventricular arrhythmias in patients treated with methadone for opioid dependence

Purpose  

Over the last decade, there has been a significant rise in reported cases of methadone induced QT prolongation (QTP) and Torsades de Pointes (TdP) in patients treated for opioid dependence. Optimal management of these patients is challenging.     

Osteolytic sinusitis and pneumomediastinum: deceptive otolaryngologic complications of cocaine abuse

Recreational cocaine abuse via intranasal "snorting," "free-base" smoking, "body-packing," or intravenous injection can be lethal. Increasing illicit use of cocaine hydrochloride and the misuse of legal over-the-counter (OTC) nasal drugs are known causative agents of nasal septal perforation with loss of taste and smell. Although 2 to 3 mg/kg is the recommended maximum dose for topical anesthesia, cocaine snorters may use 1,000 mg or more daily on a "run." Furthermore, the newer route of smoking the extracted volatile "free-base" form of the adulterated street drug provides a plasma concentration producing the same physiological and subjective effects of intravenous cocaine. Presented are two cases exemplifying unusual complications of cocaine abuse: 1. total nasal septal bony and cartilaginous necrosis with resultant saddle-nose deformity and osteolytic sinusitis secondary to chronic intranasal "snorting" and 2. tracheobronchial rupture with pneumomediastinum secondary to smoking "free-base" cocaine.     

Hand-assisted laparoscopic gastric bypass does not improve outcome and increases costs when compared to open gastric bypass for the surgical treatment of obesity

BACKGROUND: Hand-assisted laparoscopic Roux-en-Y gastric bypass (Hand-Lap GB) has been adopted by some surgeons to treat morbid obesity because it is easier to perform than the total laparoscopic procedure, but to date no study has compared the outcomes of patients undergoing the Hand-Lap GB to those obtained with the open procedure (Open GB). We hypothesized that patients undergoing Hand-Lap GB would lose a similar amount of weight when compared to Open GB patients, while experiencing no increase in complications, a shorter hospital stay, and lower overall costs of care, in part as a result of fewer incisional hernias requiring subsequent surgery. METHODS: Nonrandomized, prospective data were collected on all patients undergoing proximal GB via Hand-Lap or open approaches between May 1998 and July 1999. Our first 25 Hand-Lap GB procedures, performed in selected patients (with no extensive previous abdominal surgery) referred to two of us (E.J.D, M.A.S), were compared to all other (n = 62) concurrent open proximal GB performed by the group during this period of time in patients with body mass index (BMI) <50 kg/m2. RESULTS: Preoperatively, Hand-Lap GB patients did not differ from Open GB patients in age (40 ± 11 vs 43 ± 11 years), gender (92% female vs 81% female), incidence or type of preoperative comorbid conditions, preoperative weight (282 ± 33 vs 280 ± 37 lb), or BMI (45.5 ± 5.4 vs 44.1 ± 3.3 kg/m2). (Data given as mean ± standard deviation). Although length of hospital stay did not differ between groups (3.6 ± 1.3 vs 4.2 ± 4.6 days), total hospital costs were significantly higher for Hand-Lap GB ($14,725 ± 3089 vs. $10,281 ± 3687, p <0.01 ANOVA). One patient in the Open GB group developed an anastomotic leak from the gastrojejunostomy. Follow-up revealed that Hand-Lap GB patients had a similar risk of postoperative complications as the Open GB group, including marginal ulcer (16% vs 14.5%), stomal stenosis (24% vs 23%), and, most notably, incisional hernia (20% vs 27%). There were no major wound infections or deaths in either group. One patient in each group developed a postoperative small bowel obstruction. Loss of excess weight in Hand-Lap GB patients at 12 months postoperatively was 66 ± 14% vs 77 ± 14% in the Open GB group. CONCLUSIONS: The Hand-Lap GB yielded good weight reduction in a population of morbidly obese patients, but at a higher cost for hospital care than Open GB. There was no decrease in the incidence of incisional hernias with the Hand-Lap GB procedure. Although Hand-Lap GB appears to be safe and effective, its failure to provide a decrease in hospital stay or risk of incisional hernia requiring subsequent surgical repair is significant. The primary role for the Hand-Lap GB procedure should therefore be to aid surgeons in developing skills to climb the steep learning curve for total laparoscopic gastric bypass, since Hand-Lap GB does not improve patient outcome and increases cost in comparison to the open GB procedure.     

"Real world" atypical antipsychotic prescribing practices in public child and adolescent inpatient settings

This article examines the factors that influence antipsychotic use among youth treated in public inpatient facilities. By combining data from 11 focus groups, a survey of 43 researchers and clinicians, and a chart review of 100 closed patient charts, we investigated the interplay between physicians' and staff members' perceptions of problems related to antipsychotic prescribing, their beliefs concerning optimal approaches, their actual recorded prescribing behaviors, and the discrepancies between their beliefs and their recorded practices. We discovered that antipsychotics are prescribed broadly to treat a variety of conditions, including nonpsychotic disorders among children in public inpatient facilities. Despite overall expert consensus regarding "best practices," physicians described systemic obstacles that prevent the application of these practices, and our data confirmed that best practices are not always followed. Future research should be done with this patient population and should investigate the factors that influence antipsychotic use among inpatient youth.
