Deconstructing Differential Drug Coverage within a Malaysian Media Source.

Many researchers have noted that media coverage of drugs can be sensationalized and/or have questionable accuracy. Additionally, it has been alleged that the media often treats all drugs as harmful and can fail to differentiate between different types of drugs. Within this context, the researchers sought to deconstruct how media coverage was similar and/or different according to drug type within a national media outlet in Malaysia. Our sample comprised 487 news articles published over a two-year period. Articles were coded to reflect thematic differences in drug framing. We focus on five drugs widely used in Malaysia (amphetamines, opiates, cannabis, cocaine, and kratom) and assess the most frequent themes, crimes, and locations mentioned in reference to each drug. All drugs were primarily covered in a criminal justice context, and articles highlighted concern about the spread of these drugs and their abuse. Drug coverage varied, particularly in association with violent crimes, specific regions, and discussion of legality. We find evidence of both similarities and differences in how drugs were covered. Variation in coverage demonstrated that certain drugs were deemed a heightened threat, as well as reflected broader social/political processes shaping ongoing debates over treatment approaches and legality.

Public Perceptions toward Kratom (Mitragyna Speciosa) Use in Malaysia.

Kratom (Mitragyna speciosa), an indigenous medicinal plant of Southeast Asia, is believed to be harmful. We compared the perceptions toward kratom use among kratom users and non-users in Malaysia. 356 respondents (137 kratom users and 219 non-users) were recruited for this cross-sectional study. The majority of respondents were male (60%, n = 212/356), Malays (88%), and 51% were ≥37 years old. Non-users showed higher unadjusted odds of reporting a perception that kratom use can cause addiction (OR = 6.72, CI: 3.91-11.54, p < .0001), withdrawal symptoms (OR = 7.58, CI: 4.62-12.42, p < .0001), illicit drug use problems (OR = 10.12, CI: 6.14-16.68, p < .0001), impaired social-functioning (OR = 12.05, CI: 7.24-20.05, p < .0001), and health problems (OR = 10.44, CI: 6.32-17.24, p < .0001). Similarly, non-users viewed kratom policies differently from kratom users, displaying increased odds of reporting the belief that kratom use and sales must be regulated with stringent laws (OR = 5.75, CI: 3.61-9.18, p < .0001), and kratom should be regulated instead under the Dangerous Drugs Act 1952 to overcome kratom use problems (OR = 8.26, CI: 4.94-13.82, p < .0001). Because of the disconnect in kratom use perceptions and personal experiences between kratom users and non-users, hastily criminalizing kratom without investigating carefully its scientific merits can significantly impede future kratom research.

Late referral of cancer patients with malnutrition to dietitians: a prospective study of clinical practice.

PURPOSE: Malnutrition (MN) in cancer is common but underdiagnosed. Dietitian referrals may not occur until MN is established. We investigated cancer patient characteristics (demographics, nutritional status, and nutrition barriers) on referral to oncology dietitians. We also examined referral practices and prevalence of missed referral opportunities. METHODS: This was a naturalistic multi-site study of clinical practice. Data from consecutive referrals were collected in inpatient and outpatient settings. Demographics, nutritional status (weight, body mass index (BMI), weight loss in the preceding 3-6 months, oral intake, nutrition barriers), referral reasons, and use of screening were recorded. Missed opportunities for earlier referral were also noted. RESULTS: Two hundred patients were included (60% male, 51% inpatients). Half had gastrointestinal and hepatobiliary cancers. The majority were on antitumor treatment. Two-thirds had lost ≥ 5% body weight. Forty percent were overweight or obese. Seventy percent had ≥ 2 nutritional barriers. Most common nutrition barriers were anorexia, nausea, and early satiety. Greater weight loss and lower food intake were associated with ≥ 2 barriers. Weight loss was the most common referral reason. Screening was used in 35%. Referrals should have occurred sooner in nearly half (45%, n = 89). CONCLUSIONS: Cancer patients were referred late to a dietitian, with multiple nutritional barriers. Most referrals were for established weight loss (WL). WL may be masked by pre-existing obesity. Almost half had missed earlier referral opportunities; screening was infrequent. Over one-quarter should have been re-referred sooner. There is a clear need for clinician education. Future research should investigate the optimal timing of dietitian referral and the best nutrition screening tools for use in cancer.

The Scheduling of Kratom and Selective Use of Data.

Kratom is a traditional drug from Southeast Asia that has been an emerging new substance in the United States. On August 30, 2016, the DEA announced the intention to emergency schedule kratom into Schedule I. To support this decision, the DEA cited an increase in drug seizures of kratom and an increase in calls to poison control concerning kratom. However, a short time later, on October 12, 2016, the DEA withdrew the intent to schedule kratom after public and congressional backlash. The withdrawal by the DEA was somewhat unprecedented. To better understand both decisions, the current article examines the evidence the DEA cited to support their decision to emergency schedule kratom and the degree and type of media coverage of kratom to determine if a media-driven drug panic occurred.

The nutritional management of type 3c (pancreatogenic) diabetes in chronic pancreatitis.

Type 3c diabetes mellitus (T3cDM), also known as pancreatogenic diabetes, refers to diabetes caused by disease of the exocrine pancreas. T3cDM is not commonly recognised by clinicians and frequently it is misclassified as T1DM, or more commonly, T2DM. T3cDM can be difficult to distinguish from T1DM and T2DM, and it often co-exists with the latter. The aim of this review is to describe T3cDM, along with its complications, diagnosis and management. We focus on the nutritional implications of T3cDM for those with chronic pancreatitis, and provide a practical guide to the nutritional management of this condition.

Do You Get What You Paid For? An Examination of Products Advertised as Kratom.

Although some novel psychoactive substances (NPS) are newly discovered chemicals, others are traditional or indigenous substances that are introduced to new markets. One of these latter substances is a plant many people refer to as kratom. Indigenous to Southeast Asia and used for a variety of instrumental and recreational purposes, kratom has recently become available to Western drug users. Kratom is somewhat unique in that the plant contains two different psychoactive chemicals, which have both stimulant (mitragynine) and narcotic (7-hydroxymitragynine) properties. Thus, kratom may appeal to different types of drug users for reasons other than curiosity. In the current study, 15 samples of products that were either directly advertised as kratom or were listed in the results of a web search (but were not directly advertised as kratom) were purchased for testing. After laboratory testing, it was determined that all products advertised as kratom contained the active chemical mitragynine, but 7-hydroxymitragynine was not detected in any of the samples. Implications are discussed.

Regulating a novel drug: an evaluation of changes in use of Salvia divinorum in the first year of Florida's ban.

BACKGROUND: A plant with dissociative and psychoactive properties began to attract the attention of the media and United States policymakers following a well-publicized suicide in 2006 and reports that the plant served as a 'legal high' and substitute for cannabis. As a result, Salvia divinorum and its active ingredient, salvinorin A, were classified as Schedule I substances by the Florida Legislature on July 1, 2008. As of yet, no research has explored the efficacy of this policy or similar policies in other jurisdictions. METHODS: Three self-report studies collected from young adults both prior to and following the policy's implementation are employed to investigate the potential relationship between the policy and usage rates. In addition, law enforcement personnel from the state's most populated areas were interviewed to determine the extent to which they were encountering salvia in their work. RESULTS: It was indicated that less than two-thirds of those surveyed were aware of the drug's legal status. Lifetime prevalence of salvia use was largely unchanged. However, the rates of self-reported past year and past month use in Florida were significantly lower following the scheduling. Though use of Salvia divinorum appears to have decreased, perceptions of peer use increased markedly. Law enforcement officers and laboratories reported rarely, if ever, dealing with cases of salvia possession. CONCLUSIONS: Data suggests the classification of Salvia divinorum as a Schedule I drug was followed by a substantial reduction in recreational use. We caution that other factors may have influenced use, that the efficacy of scheduling novel substances is likely to vary by drug type, that such a reduction in reported use may only exist transiently until a sophisticated illicit market develops to replace the legitimate one, and that a state's success in regulating salvia may be related to their regulation of and enforcement of other drug prohibitions.

Legally high? Legal considerations of Salvia divinorum.

The legal status of the hallucinogenic plant Salvia divinorum has been rapidly changing. Legal prohibitions on this plant native to Oaxaca, Mexico have emerged at the state level, a phenomenon that has not occurred since the passage of the Controlled Substances Act (CSA). Included will be a brief description of the plant that has only recently crept into the popular American consciousness, and a review of the different legal mechanisms through which states have controlled the plant and the pending legislation proposing controls. Lastly, the implications of various state laws are discussed.

Salvia divinorum use among a college student sample.

The recreational use of Salvia divinorum has received increased attention by media outlets and policy-makers in recent years. The vast absence of research to guide the dissemination of information has prompted this research note describing the use of this substance in a large public institution of higher education. The prevalence of Salvia divinorum is described in this context and a description of patterns of use, methods of acquisition, and a subjective estimation of continuance are proffered.

Use of record linkage between a statewide genetics service and a Birth Defects/Congenital Malformations Register to determine use of genetic counselling services.

The Birth Defects/Congenital Malformations Register of the Victorian Department of Human Services contains detailed, confidential information on over 2,000 babies born with a birth defect each year in Victoria, Australia, representing approximately 3% of the annual number of births. For 1991 and 1993, the type of anomaly was categorised as warranting a high, moderate, or low need of referral for genetic counselling, depending on risk of recurrence and possible genetic cause. The Victorian Clinical Genetics Service at the Murdoch Institute, Melbourne, offers free, centralised genetic counselling services for the entire state. A comparison of case records between the two agencies has shown little difference in overall use of genetic counselling between 1991 (17%) and 1993 (16%). Rate of uptake in the "high need" category improved only slightly during that period, from 40% in 1991 to 43% in 1993. Utilization of genetic counselling services did not vary disproportionately with mother's country of birth, but was higher for older mothers. As was expected, rates were highest when a baby was born at the only hospital that provides on-site genetic counselling services. Even where a statewide genetic counselling service is in place, it is disappointing that over half of those judged at high need for genetic counselling are not making use of this service. This study will provide baseline information to which future studies can be compared. Using the same study methodology, it will be possible to examine whether the uptake rate increases in accordance with increased genetic services.

Validating a statewide data collection: differences in information technology resources between hospitals.

The Victorian Perinatal Data Collection Unit (VPDCU) is a statewide data collection established to collect information on the health of mothers and their babies. A Perinatal Morbidity Statistics Form is required to be completed for every birth, then forwarded to the VPDCU. Many medical record departments are responsible for both forwarding the forms to the VPDCU and responding to queries on data accuracy. In 1996 we undertook to determine if we were receiving a perinatal form for every birth occurring at every hospital in the State with obstetric beds. Health information managers were requested to supply a listing of all babies born at their hospitals in 1995-129 hospitals responded. Overall 62,759 births were validated. The VPDCU had received a perinatal form for 99.6 per cent of these births, with 251 missing forms. Reasons why the VPDCU had not received the forms were investigated.

Acceptable levels for the breathing resistance of respiratory apparatus: results for men over the age of 45.

Tolerance of additional external resistance to inspiration has been investigated in a group of coalworkers older than 45 years. Peak inspiratory pressure, external respiratory work rate, ventilation, and gas exchange were measured, during periods with and without one of four inspiratory resistances, on 41 subjects walking on a treadmill. Minute volume was reduced, breathing frequency was unchanged and oxygen uptake and carbon dioxide elimination were reduced by the presence of resistance. It was established that, at the workload studied, older men were able to tolerate inspiratory resistance to at least the same extent as younger men, when the respiratory work was expressed in terms of unit ventilation. It is suggested that the acceptable level of breathing resistance established for younger men can also be applied to older workers.

Cornea-damaging proteases of Serratia marcescens.

Fractionation of the culture supernatant fluids of Serratia marcescens, strain BG, by ammonium sulfate precipitation, isoelectric focusing, ion-exchange chromatography, hydroxyapatite adsorption chromatography, and gel filtration failed to separate the rabbit cornea-damaging activity and the in vitro protease activity of the preparations. Two proteases having similar molecular weights (44,000), estimated by gel filtration, and isoelectric points of approximately 5.0 and 5.3 were obtained free of detectable amounts of other known extracellular serratia enzymes. Heating a mixture of the two proteases for 15 minutes at 60 degrees C. resulted in complete loss of protease and cornea-damaging activities. Production of protease and cornea-damaging activities was inhibited by ammonium sulfate. The results support the conclusion that extracellular proteases produced in vitro by S. marcescens can elicit rapid and extensive damage to the rabbit cornea.

Physicochemical fractionation of extracellular cornea-damaging proteases of Pseudomonas aeruginosa.

Fractionation of the culture supernatant fluids of a cornea-virulent strain of Pseudomonas aeruginosa by ammonium sulfate precipitation, diafiltration, isoelectric focusing, ion-exchange chromatography, gel filtration, and sucrose density gradient centrifugation failed to separate the rabbit cornea-damaging activity and the in vitro protease activity of the preparations. Three proteases having similar molecular weights (approximately 20,000) and isoelectric points of approximately 4.6, 5.8, and 8.8 were obtained free of detectable amounts of other known extracellular pseudomonal enzymes. Heating a mixture of the three proteases for 15 min at 80 C resulted in complete loss of protease and cornea-damaging activities. The sterile culture filtrate of a nonproteolytic but lethal toxin-producing strain of P. aeruginosa did not contain cornea-damaging activity. Cultivation of the proteolytic strain in broth containing 4.7% ammonium sulfate yielded a culture supernatant fluid free of protease and cornea-damaging activities. The results obtained support the conclusion that a cornea-virulent strain of P. aeruginosa can produce, in vitro, at least three different extracellular proteases capable of eliciting rapid and extensive damage to rabbit corneas.
