Administration UL of ingredients (zinc, vitamin B3, and magnesium).CONCLUSIONS: Ninety percent of “T booster” supplements claimed to boost T. However, only 24.8% of these had data to support these claims. A total of 10.1% contained components with data suggesting a negative effect on T. Many had supra-therapeutic doses of vitamins and minerals, occasionally over the UL. Patients should be informed that “T booster” supplements may not have ingredients to support their claims.]]>

BACKGROUND: This study evaluated the effect of vitamin C on post-laparoscopic shoulder pain (PLSP) in patients undergoing benign gynecological surgery during the first 72 h. METHODS: Sixty patients (aged 20 to 60 years, with American Society of Anesthesiologists physical status classification I or II) scheduled for elective laparoscopic hysterectomy were enrolled in this study. The vitamin C group (Group C) received 500 mg of vitamin C in 50 ml of isotonic saline infusion intravenously twice a day from the day of surgery to the third day after surgery. Patients in the saline group (Group S) received the same volume of isotonic saline over the same period. Post-operative analgesic consumption, pain scores of the incision site and the shoulder, and the incidence of PLSP were all evaluated at 1, 6, 24, 48, and 72 h following surgery. RESULTS: Cumulative post-operative fentanyl consumption was significantly less in Group C at 24 and 48 h after surgery (P = 0.002, P = 0.012, respectively). The pain intensity of PLSP was also significantly lower in Group C 24 h after the operation (P = 0.002). Additionally, the incidence of PLSP was significantly lower in Group C 24 and 48 h after the operation (P = 0.002, P = 0.035, respectively). CONCLUSIONS: Perioperative intravenous administration of vitamin C (500 mg, twice a day) reduced post-operative analgesic consumption and significantly lowered the pain intensity and incidence of PLSP.

Metabolic abnormalities and catheter-related infections are common complications of parenteral nutrition (PN). Particulate contamination is a catheter-related complication can occur when administering PN: mixing the electrolytes, trace elements, vitamins into the PN, or puncturing a rubber stopper at the PN formulation. In addition, the aggregation of the components of the PN solution by a drug incompatibility reaction could be related to particulate contamination. PN contaminated with precipitates, insoluble particles, and bacteria was reported as the cause of the death of a patient. The Food and Drug Administration recommended that the filters be used during PN administration. In-line filters can retain the bacteria and insoluble particles in PN solutions, and prevent their infusion into the patient. Therefore, in-line filters are recommended to prevent catheter-related complications that can occur during PN infusion. A 0.2µ filter for lipid-free PN and a 1.2µ filter for lipid-containing PN solutions can be used. On the other hand, when a filter is applied, the infusion rate can decrease and the economic burden will increase for patients requiring long-term PN. In addition, small particles, such as viruses, polymers, and proteins cannot be filtered out completely. In conclusion, in-line filers are recommended to prevent catheter-related complications that can occur during PN administration, but there are no international standardized guidelines. Therefore, standardized guidelines will be needed based on evidence accompanied by clinical trials. In addition, in-line filter applications should be considered in the clinical field depending on the patient's condition.

BACKGROUND: The consumption of dietary supplements is increasing in Korea. The aim of this study is to assess the prevalence, types, and trends of dietary supplement (DS) use in Korean adults. METHODS: We analyzed the Nutrition Survey data of Korean aged 19 years old or older from the 2015 Korea National Health and Nutrition Examination Survey. Two thousand and six hundred twenty one men and 3,324 women totaling 5,945 adults were included. The prevalence of DS use was calculated by two methods, i.e., consumption experience of more than two weeks during previous one year and current consumption. Each reported DS in the one day 24 hour recall was coded based on ingredients according to the 2016 Korean Food and Drug Administration Notification. RESULTS: The prevalence (standard error) of current DS use was 18.4% (1.2) for men, 27.4% (1.1) for women. Those with DS use for longer than two weeks during previous one year were 35.2% (1.5), and 50.4% (1.2), for men and women respectively. Multi-vitamin mineral supplement (89.6/103 persons) was the most frequently consumed DS in Korean adults followed by vitamin C (66.2/103 persons), omega 3 fatty acid (49.5/103 persons), Panax ginseng (27.3/103 persons), and probiotics (22.2/103 persons) in listing. CONCLUSIONS: The trend for DS use in Korean adults is changing as well as increasing. These factors should be considered in patient care.

Methemoglobinemia is a condition in which the iron portion of hemoglobin, which binds to oxygen, is oxidized to produce methemoglobin, which increases blood concentration. There are many causes of methemoglobinemia, the most common being food, drugs, and chemicals. A 75-year-old male patient who had taken an herbicide did not notice any nonspecific symptoms. However, after 4 hours, his methemoglobin levels increased to 17.1%, while after 7 hours it increased to 26.5%, at which time intravenous administration of methylene blue 1 mg/kg (an antidote) was started. After a total of five doses of methylene blue at 1 mg/kg due to reactive methemoglobinemia for about 36 hours, the methemoglobin levels increased to 23.7%. Because no more methylene blue could be administered, 10 g of ascorbic acid (vitamin C) was administered intravenously. After 82 hours, ascorbic acid 10 g was administered six times for repeated reactive methemoglobinemia. No additional reactive methemoglobinemia was observed. The ventilator and endotracheal tube were successfully removed on day 5 after admission.

An adequate supply of vitamin D is considered necessary for osteoporosis management and fracture prevention. Intermittent high-dose vitamin D supplementation is an effective and convenient way to achieve and maintain sufficient vitamin D status. However, the long-term effectiveness of supplementation for preventing falls and fractures is unclear, and some deleterious effects of such treatments have been reported. Concerning these issues, the Korean Society for Bone and Mineral Research task force team reviewed previous clinical trials and provided the following perspectives based on current evidence: 1) An adequate supply of vitamin D is necessary for preventing falls and fractures in postmenopausal women and men older than 50 years. An oral intake of 800 to 1,000 IU/day of vitamin D is generally recommended. 2) Care should be taken concerning the routine use of intermittent high-dose vitamin D, as large-scale clinical trials showed increased risk of falls or fractures after high-dose vitamin D administration. Intermittent high-dose vitamin D supplementation is recommendable only in cases of malabsorption or when oral administration is not suitable. 3) Monitoring of the serum level of 25-hydroxy-vitamin D (25[OH]D) is advisable, especially when intermittent high-dose vitamin D is used for supplementation. The task force team suggests that a serum 25(OH)D level of >20 ng/mL is generally appropriate for the prevention of osteoporosis, and that a serum 25(OH)D level of >30 ng/mL is probably helpful both for the management of osteoporosis and the prevention of fractures and falls. However, serum 25(OH)D level >50 ng/mL (this value can vary depending on the measurement method used) is unnecessary and may be undesirable. These perspectives are relevant for the management of osteoporosis, falls, or fractures. Other metabolic bone diseases or non-skeletal disorders are not within the scope of these perspectives.

OBJECTIVETo investigate the status of folic acid (FA) supplementation and determinants of its use in pregnant Chinese women.

METHODSIn this cross-sectional study, questionnaires were used to collect information of participants and FA supplementation. Women were recruited between 6 and 12 weeks postpartum in Tianjin, China, between July 2015 and July 2016.

RESULTSA total of 1,921 women were recruited in the study. Approximately 93.1% of the study participants used FA, while 14.4% of the women taking FA from three months prior to preconception to three months post-conception. Women who took FA for three months prior to preconception through at least three months into their pregnancy were more likely to be between 30 and 34 years old (OR = 2.91, 95% CI: 1.15, 7.33), employed (OR = 2.07, 95% CI: 1.17, 3.67), primigravida (OR = 5.20, 95% CI: 3.02, 8.96), married to spouses with an intermediate education level (OR = 2.92, 95% CI: 1.45, 5.89), and earn a high family income (OR = 3.19, 95% CI: 1.57, 6.49).

CONCLUSIONThe prevalence of periconceptional FA intake was far below the requirements of the National Health and Family Planning Commission of China; therefore, knowledge of FA supplementation should be strengthened among women who are or planning to become pregnant.

BACKGROUND: Although there are several available management strategies for treatment of both acute pain of herpes zoster (HZ) and postherpetic neuralgia (PHN), it is difficult to treat them adequately. OBJECTIVE: The aim of this study was to evaluate the efficacy of intravenously administrated vitamin C on acute pain and its preventive effects on PHN in patients with HZ. METHODS: Between September 2011 and May 2013 eighty-seven patients who were admitted for HZ were assessed according to age, sex, underlying diseases, duration of pain and skin lesion, dermatomal distribution, and PHN. It was a randomized controlled study, in which 87 patients were randomly allocated into the ascorbic acid group and control group. Each patient received normal saline infusion with or without 5 g of ascorbic acid on days 1, 3, and 5 then answered questionnaires that included side effects and pain severity using visual analogue scale on days 1, 2, 3, 4, and 5. After discharge, the severity of pain was obtained at out-patient clinic or by telephone on weeks 2, 4, 8, and 16. RESULTS: There was no differences in severity of pain on patients' age, sex, underlying diseases, duration of pain and skin lesion and dermatomal distribution between two groups (p>0.05). Since 8th week, pain score in ascorbic acid treatment group was significantly lower than control group (p <0.05). The incidence of PHN was significantly lower in the treatment group compared to control group (p=0.014). The changes of overall pain score was significantly different between the two groups (p<0.05). CONCLUSION: Intravenously administered ascorbic acid did not relieve acute HZ pain; but is effective for reducing the incidence of PHN.

The present study was to evaluate effects of vitamin E on intravenous administration of lidocaine-induced antinociception. Experiments were carried out using male Sprague-Dawley rats. Orofacial formalin-induced nociceptive behavioral responses were used as the orofacial animal pain model. Subcutaneous injection of formalin produced significant nociceptive scratching behavior. Intraperitoneal injection of 5 and 10 mg/kg of lidocaine attenuated formalin-induced nociceptive behavior in the 2nd phase, compared to the vehicle-treated group. Intraperitoneal injection of 1 g/kg of vitamin E also attenuated the formalin-induced nociceptive behavior in the 2nd phase, compared to the vehicle-treated group. However, low dose of vitamin E (0.5 g/kg) did not affect the nociceptive behavioral responses produced by subcutaneous injection of formalin. The present study also investigated effects of intraperitoneal injection of both vitamin E and lidocaine on orofacial formalin-induced behavioral responses. Vehicle treatment affected neither formalin-induced behavioral responses nor lidocaine-induced antinociceptive effects. However, intraperitoneal injection of 0.5 g/kg of vitamin E enhanced the lidocaine-induced antinociceptive effects in the 2nd phase compared to the vehicle-treated group. Intraperitoneal injection of naloxone, an opioid receptor antagonist, did not affect antinociception produced by intraperitoneal injections of both vitamin E and lidocaine. These results suggest that treatment with vitamin E enhances the systemic treatment with lidocaine-induced antinociception and reduces side effects when systemically treated with lidocaine. Therefore, the combined treatment with vitamin E and lidocaine is a potential therapeutic for chronic orofacial pain.

BACKGROUND/AIMS: The aims of this study were to compare the bowel-cleansing efficacy, patient affinity for the preparation solution, and mucosal injury between a split dose of poly-ethylene glycol (SD-PEG) and low-volume PEG plus ascorbic acid (LV-PEG+Asc) in outpatient scheduled colonoscopies. METHODS: Of the 319 patients, 160 were enrolled for SD-PEG, and 159 for LV-PEG+Asc. The bowel-cleansing efficacy was rated according to the Ottawa bowel preparation scale. Patient affinity for the preparation solution was assessed using a questionnaire. All mucosal injuries observed during colonoscopy were biopsied and histopathologically reviewed. RESULTS: There was no significant difference in bowel cleansing between the groups. The LV-PEG+Asc group reported better patient acceptance and preference. There were no significant differences in the incidence or characteristics of the mucosal injuries between the two groups. CONCLUSIONS: Compared with SD-PEG, LV-PEG+Asc exhibited equivalent bowel-cleansing efficacy and resulted in improved patient acceptance and preference. There was no significant difference in mucosal injury between SD-PEG and LV-PEG+Asc. Thus, the LV-PEG+Asc preparation could be used more effectively and easily for routine colonoscopies without risking significant mucosal injury.
