Avian influenza viruses in New Zealand wild birds, with an emphasis on subtypes H5 and H7: Their distinctive epidemiology and genomic properties.

The rapid spread of highly pathogenic avian influenza (HPAI) A (H5N1) viruses in Southeast Asia in 2004 prompted the New Zealand Ministry for Primary Industries to expand its avian influenza surveillance in wild birds. A total of 18,693 birds were sampled between 2004 and 2020, including migratory shorebirds (in 2004-2009), other coastal species (in 2009-2010), and resident waterfowl (in 2004-2020). No avian influenza viruses (AIVs) were isolated from cloacal or oropharyngeal samples from migratory shorebirds or resident coastal species. Two samples from red knots (Calidris canutus) tested positive by influenza A RT-qPCR, but virus could not be isolated and no further characterization could be undertaken. In contrast, 6179 samples from 15,740 mallards (Anas platyrhynchos) tested positive by influenza A RT-qPCR. Of these, 344 were positive for H5 and 51 for H7. All H5 and H7 viruses detected were of low pathogenicity confirmed by a lack of multiple basic amino acids at the hemagglutinin (HA) cleavage site. Twenty H5 viruses (six different neuraminidase [NA] subtypes) and 10 H7 viruses (two different NA subtypes) were propagated and characterized genetically. From H5- or H7-negative samples that tested positive by influenza A RT-qPCR, 326 AIVs were isolated, representing 41 HA/NA combinations. The most frequently isolated subtypes were H4N6, H3N8, H3N2, and H10N3. Multivariable logistic regression analysis of the relations between the location and year of sampling, and presence of AIV in individual waterfowl showed that the AIV risk at a given location varied from year to year. The H5 and H7 isolates both formed monophyletic HA groups. The H5 viruses were most closely related to North American lineages, whereas the H7 viruses formed a sister cluster relationship with wild bird viruses of the Eurasian and Australian lineages. Bayesian analysis indicates that the H5 and H7 viruses have circulated in resident mallards in New Zealand for some time. Correspondingly, we found limited evidence of influenza viruses in the major migratory bird populations visiting New Zealand. Findings suggest a low probability of introduction of HPAI viruses via long-distance bird migration and a unique epidemiology of AIV in New Zealand.

Rural patient and provider perceptions of telehealth implemented during the COVID-19 pandemic.

BACKGROUND: Understanding perceptions of telehealth  implementation from patients and providers can improve the utility and sustainability of these programs, particularly in under-resourced rural settings. The purpose of this study was to evaluate both patient and provider perceptions of telehealth visits in a large rural healthcare system during the COVID-19 pandemic. To promote sustainability of telehealth approaches, we also assessed whether the percentage of missed appointments differed between in-person and telehealth visits. METHODS: Using anonymous surveys, we evaluated patient preferences and satisfaction with telehealth visits from November 2020 -March 2021 and assessed perceptions of telehealth efficiency and value among rural providers from September-October 2020. We examined whether telehealth perceptions differed according to patients' age, educational attainment, insurance status, and distance to clinical site and providers' age and length of time practicing medicine using ANOVA test. We also examined whether the percentage of missed appointments differed between in-person and telehealth visits at a family practice clinic within the rural healthcare system from April to September 2020 using a Chi-square test. RESULTS: Over 73% of rural patients had favorable perceptions of telehealth visits, and satisfaction was generally higher among younger patients. Patients reported difficulty with scheduling follow-up appointments, lack of personal contact and technology challenges as common barriers. Over 80% of the 219 providers responding to the survey reported that telehealth added value to their practice, while 36.6% agreed that telehealth visits are more efficient than in-person visits. Perception of telehealth value and efficiency did not differ by provider age (p = 0.67 and p = 0.67, respectively) or time in practice (p = 0.53 and p = 0.44, respectively). Technology challenges for the patient (91.3%) and provider (45.1%) were commonly reported. The percentage of missed appointments was slightly higher for telehealth visits compared to in-person visits, but the difference was not statistically significant (8.7% vs. 8.0%; p = 0.39). CONCLUSIONS: Telehealth perceptions were generally favorable among rural patients and providers, although satisfaction was lower among older patients and providers. Our findings suggest that telehealth approaches may add value and efficiency to rural clinical practice. However, technology issues for both patients and providers and gaps in care coordination need to be addressed to promote sustainability of telehealth approaches in rural practice.

Impact of Critical Material Attributes (CMAs)-Particle Shape on Miniature Pharmaceutical Unit Operations.

The U.S. Food and Drug Administration (FDA) emphasizes drug product development by Quality by Design (QbD). Critical material attributes (CMAs) are a QbD element that has an impact on pharmaceutical operations and product quality. Pharmaceutical drugs often crystallize as needle-shaped (a CMA) particles and affect the process due to poor flowability, low bulk density, and high compressibility, and eventually the product performance. In this study, the product obtained from crystallization was needle-shaped Ciprofloxacin HCl (CIPRO), formed lumps during drying, and compacted during processing through feeders. To delump small amounts of materials and break the needles, multiple available devices (mortar-pestle, Krups grinder) and custom-made grinder were assessed before formulation. The processed CIPRO powder was then used to make tablets in the miniature tablet manufacturing unit developed by the team at MIT. The critical quality attributes (CQA) of the tablets, set by the United States Pharmacopeia (USP), were then assessed for the drug powder processed with each of these devices. Powder properties comparable to commercial CIPRO were obtained when the custom MIT-designed grinder was used, leading to tablets that meet the USP criteria, with comparable dissolution profiles of those for marketed CIPRO tablets. This study demonstrates how needle-shaped crystals have an impact on pharmaceutical operations, even if it is on a miniature scale, and how proper shape and subsequent flow properties can be obtained by processing the particles through the MIT team-designed grinder.

Outdoor walking rounds: combining resident education and wellness.

BACKGROUND: It is challenging to achieve quality teaching on a busy resident service. Teams must balance the competing drivers of patient care, clinical efficiency, patient satisfaction and resident learning. Our novel outdoor walking rounds improve both the quality of resident instruction and their physician wellness without negatively affecting patient care. METHODS: Our team meets outside for attending rounds on the sidewalks or hiking trails near our hospital. The residents present their clinical plans as we walk. We are able to achieve more in-depth clinical discussions and teaching than with traditional rounds conducted inside. Residents were surveyed to compare their experiences with traditional rounds. RESULTS: Twenty-seven residents were surveyed over 5 years (29.6% were first-year residents, 33.3% were second-year residents and 37.0% were third-year residents): 81% of residents indicated that walking rounds improved the time dedicated to teaching; 100% of residents believed that the quality of teaching had improved; 70% of residents indicated that walking rounds improved their sense of physician wellness; and 59% of residents identified that walking rounds were as efficient, or more efficient, than traditional rounds. DISCUSSION: Striving to provide in-depth resident clinical teaching without negatively affecting the quality and efficiency of patient care is a tall order. Outdoor walking rounds are a teaching method that combines dedicated non-distracted time for resident teaching with exercise. Our study indicates that this teaching method improves the quantity and quality of dedicated teaching time, improves resident physician wellness and does so in an innovative way that maintains efficient patient care.

On-Demand Manufacturing of Direct Compressible Tablets: Can Formulation Be Simplified?

PURPOSE: Oral direct compressible tablets are the most frequently used drug products. Manufacturing of tablets requires design and development of formulations, which need a number of excipients. The choice of excipients depends on the concentration, manufacturability, stability, and bioavailability of the active pharmaceutical ingredients (APIs). At MIT, we developed a miniature platform for on-demand manufacturing of direct compressible tablets. This study investigated how formulations could be simplified to use a small number of excipients for a number of different API's in which long term stability is not required. METHOD: Direct compressible tablets of five pharmaceutical drugs, Diazepam, Diphenhydramine HCl, Doxycycline Monohydrate, Ibuprofen, and Ciprofloxacin HCl, with different drug loadings, were made using direct compression in an automated small scale system.. The critical quality attributes (CQA) of the tablets were assessed for the quality standards set by the United States Pharmacopeia (USP). RESULTS: This miniature system can manufacture tablets - on-demand from crystalline API using the minimum number of excipients required for drug product performance. All drug tablets met USP quality standards after manufacturing and after 2 weeks of accelerated stability test, except for slightly lower drug release for Ibuprofen. CONCLUSIONS: On-demand tablets manufacturing where there is no need for long term stability using a flexible, miniature, automated (integrated) system will simplify pharmaceutical formulation design compared to traditional formulations. This advancement will offer substantial economic benefits by decreasing product time-to-market and enhancing quality.

A compact, portable, re-configurable, and automated system for on-demand pharmaceutical tablet manufacturing.

Due to the complex nature of the pharmaceutical supply chain, the industry faces several major challenges when it comes to ensuring an adequate supply of quality drug products. These challenges are not only the causes of supply chain disruptions and financial loss, but can also prevent underserved and remote areas from receiving life-saving drugs. As a preliminary demonstration to mitigate all these challenges, at MIT we have developed active pharmaceutical ingredients manufacturing in a miniature platform. However, manufacturing of final oral solid dosage as tablets from drug substances had not been demonstrated. In this study, a compact, portable, re-configurable, and automated tablet manufacturing system, roughly the size of a North American household oven, [72.4 cm (length) × 53.3 cm (width) × 134.6 cm (height)] was designed, built and demonstrated. This miniature system is able to manufacture on-demand tablets from drug crystals on a scale of hundreds to thousands per day. Ibuprofen and Diazepam, each having different drug loading, were manufactured using this miniature system and meet U.S. Pharmacopeia standards. We foresee this flexible, miniature, plug-and-play pharmaceutical solids dosage manufacturing system advancing on-demand ready-to-use pharmaceuticals enabling future treatment of human diseases at the point-of-care.

An Assessment of International Family Medicine Faculty Development Priorities: Perspectives From the American Academy of Family Physicians Global Health Workshop.

INTRODUCTION: The proliferation of new family medicine training programs across the globe has increased the demand for faculty development (FD) opportunities in international settings. US-based faculty may partner with international colleagues to support FD. In 2016, the Society of Teachers of Family Medicine Global Health Educators Collaborative (STFM-GHEC) began to develop a toolkit of low-cost FD resources for this purpose. To ensure that the resources appropriately target current FD needs, STFM-GHEC organized a session at the 2016 American Academy of Family Physicians (AAFP) Global Health Workshop (GHW) to collect feedback from internationally-based and US-based faculty. METHODS: The authors presented a list of faculty development topics to attendees of an AAFP GHW session entitled "Global Faculty Development Tool Kit" on September 8, 2016, in Atlanta, Georgia. Workshop participants voted up to five times each using sticky notes for the topics they felt were of greatest need. RESULTS: Forty-five participants cast 157 votes (34 from internationally-based faculty, 123 from US-based faculty). The combined group ranked curriculum development, program evaluation, and teaching methods as the most important FD needs. Both groups identified assessment strategy and time management among the least important FD needs. Other topics such as technology training and research design varied widely between the two groups in relative importance. CONCLUSIONS: This pilot demonstrates that US-based and internationally-based family medicine faculty may differ in their perceived FD needs. This exercise may be utilized by future members in global health partnerships to understand and prioritize faculty development needs.

Social media beliefs and usage among family medicine residents and practicing family physicians.

BACKGROUND AND OBJECTIVES: Incorporation of social media (SM) use in medicine is gaining support. The Internet is now a popular medium for people to solicit medical information. Usage of social networks, such as Facebook and Twitter, is growing daily and provides physicians with nearly instantaneous access to large populations for both marketing and patient education. The benefits are myriad, but so are the inherent risks. We investigated the role providers' age and medical experience played in their beliefs and use of SM in medicine. METHODS: Using multiple state-wide and national databases, we assessed social media use by family medicine residents, faculty, and practicing family physicians with a 24-question online survey. Descriptive data is compared by age and level of medical experience. RESULTS: A total of 61 family medicine residents and 192 practicing family physicians responded. There is a trend toward higher SM utilization in the younger cohort, with 90% of resident respondents reporting using SM, half of them daily. A total of 64% of family physician respondents over the age of 45 have a SM account. An equal percentage of senior physicians use SM daily or not at all. Practicing physicians, more than residents, agree that SM can be beneficial in patient care. The vast majority of residents and physicians polled believe that SM should be taught early in medical education. CONCLUSIONS: The high utilization of SM by younger providers, high prevalence of patient use of the Internet, and the countless beneficial opportunities SM offers should be catalysts to drive curriculum development and early implementation in medical education. This curriculum should focus around four pillars: professional standards for SM use, SM clinical practice integration, professional networking, and research.
