Healing of acute anterior cruciate ligament rupture on MRI and outcomes following non-surgical management with the Cross Bracing Protocol.

OBJECTIVE: Investigate MRI evidence of anterior cruciate ligament (ACL) healing, patient-reported outcomes and knee laxity in patients with acute ACL rupture managed non-surgically with the Cross Bracing Protocol (CBP). METHODS: Eighty consecutive patients within 4 weeks of ACL rupture were managed with CBP (knee immobilisation at 90° flexion in brace for 4 weeks, followed by progressive increases in range-of-motion until brace removal at 12 weeks, and physiotherapist-supervised goal-oriented rehabilitation). MRIs (3 months and 6 months) were graded using the ACL OsteoArthritis Score (ACLOAS) by three radiologists. Mann-Whitney U tests compared Lysholm Scale and ACL quality of life (ACLQOL) scores evaluated at median (IQR) of 12 months (7-16 months) post-injury, and χ2 tests compared knee laxity (3-month Lachman's test and 6-month Pivot-shift test), and return-to-sport at 12 months between groups (ACLOAS grades 0-1 (continuous±thickened ligament and/or high intraligamentous signal) versus ACLOAS grades 2-3 (continuous but thinned/elongated or complete discontinuity)). RESULTS: Participants were aged 26±10 years at injury, 39% were female, 49% had concomitant meniscal injury. At 3 months, 90% (n=72) had evidence of ACL healing (ACLOAS grade 1: 50%; grade 2: 40%; grade 3: 10%). Participants with ACLOAS grade 1 reported better Lysholm Scale (median (IQR): 98 (94-100) vs 94 (85-100)) and ACLQOL (89 (76-96) vs 70 (64-82)) scores, compared with ACLOAS grades 2-3. More participants with ACLOAS grade 1 had normal 3-month knee laxity (100% vs 40%) and returned to pre-injury sport (92% vs 64%), compared with participants with an ACLOAS grades 2-3. Eleven patients (14%) re-injured their ACL. CONCLUSION: After management of acute ACL rupture with the CBP, 90% of patients had evidence of healing on 3-month MRI (continuity of the ACL). More ACL healing on 3-month MRI was associated with better outcomes. Longer-term follow-up and clinical trials are needed to inform clinical practice.

Clinical and epidemiologic features of SARS-CoV-2 in dogs and cats compiled through national surveillance in the United States.

OBJECTIVE: To characterize clinical and epidemiologic features of SARS-CoV-2 in companion animals detected through both passive and active surveillance in the US. ANIMALS: 204 companion animals (109 cats, 95 dogs) across 33 states with confirmed SARS-CoV-2 infections between March 2020 and December 2021. PROCEDURES: Public health officials, animal health officials, and academic researchers investigating zoonotic SARS-CoV-2 transmission events reported clinical, laboratory, and epidemiologic information through a standardized One Health surveillance process developed by the CDC and partners. RESULTS: Among dogs and cats identified through passive surveillance, 94% (n = 87) had reported exposure to a person with COVID-19 before infection. Clinical signs of illness were present in 74% of pets identified through passive surveillance and 27% of pets identified through active surveillance. Duration of illness in pets averaged 15 days in cats and 12 days in dogs. The average time between human and pet onset of illness was 10 days. Viral nucleic acid was first detected at 3 days after exposure in both cats and dogs. Antibodies were detected starting 5 days after exposure, and titers were highest at 9 days in cats and 14 days in dogs. CLINICAL RELEVANCE: Results of the present study supported that cats and dogs primarily become infected with SARS-CoV-2 following exposure to a person with COVID-19, most often their owners. Case investigation and surveillance that include both people and animals are necessary to understand transmission dynamics and viral evolution of zoonotic diseases like SARS-CoV-2.

One Health Investigation of SARS-CoV-2 in People and Animals on Multiple Mink Farms in Utah.

From July−November 2020, mink (Neogale vison) on 12 Utah farms experienced an increase in mortality rates due to confirmed SARS-CoV-2 infection. We conducted epidemiologic investigations on six farms to identify the source of virus introduction, track cross-species transmission, and assess viral evolution. Interviews were conducted and specimens were collected from persons living or working on participating farms and from multiple animal species. Swabs and sera were tested by SARS-CoV-2 real-time reverse transcription polymerase chain reaction (rRT-PCR) and serological assays, respectively. Whole genome sequencing was attempted for specimens with cycle threshold values <30. Evidence of SARS-CoV-2 infection was detected by rRT-PCR or serology in ≥1 person, farmed mink, dog, and/or feral cat on each farm. Sequence analysis showed high similarity between mink and human sequences on corresponding farms. On farms sampled at multiple time points, mink tested rRT-PCR positive up to 16 weeks post-onset of increased mortality. Workers likely introduced SARS-CoV-2 to mink, and mink transmitted SARS-CoV-2 to other animal species; mink-to-human transmission was not identified. Our findings provide critical evidence to support interventions to prevent and manage SARS-CoV-2 in people and animals on mink farms and emphasizes the importance of a One Health approach to address emerging zoonoses.

Determining the role of natural SARS-CoV-2 infection in the death of domestic pets: 10 cases (2020-2021).

OBJECTIVE: To establish a pathoepidemiological model to evaluate the role of SARS-CoV-2 infection in the first 10 companion animals that died while infected with SARS-CoV-2 in the US. ANIMALS: 10 cats and dogs that tested positive for SARS-CoV-2 and died or were euthanized in the US between March 2020 and January 2021. PROCEDURES: A standardized algorithm was developed to direct case investigations, determine the necessity of certain diagnostic procedures, and evaluate the role, if any, that SARS-CoV-2 infection played in the animals' course of disease and death. Using clinical and diagnostic information collected by state animal health officials, state public health veterinarians, and other state and local partners, this algorithm was applied to each animal case. RESULTS: SARS-CoV-2 was an incidental finding in 8 animals, was suspected to have contributed to the severity of clinical signs leading to euthanasia in 1 dog, and was the primary reason for death for 1 cat. CONCLUSIONS AND CLINICAL RELEVANCE: This report provides the global community with a standardized process for directing case investigations, determining the necessity of certain diagnostic procedures, and determining the clinical significance of SARS-CoV-2 infections in animals with fatal outcomes and provides evidence that SARS-CoV-2 can, in rare circumstances, cause or contribute to death in pets.

One Health Investigation of SARS-CoV-2 Infection and Seropositivity among Pets in Households with Confirmed Human COVID-19 Cases-Utah and Wisconsin, 2020.

Approximately 67% of U.S. households have pets. Limited data are available on SARS-CoV-2 in pets. We assessed SARS-CoV-2 infection in pets during a COVID-19 household transmission investigation. Pets from households with ≥1 person with laboratory-confirmed COVID-19 were eligible for inclusion from April-May 2020. We enrolled 37 dogs and 19 cats from 34 households. All oropharyngeal, nasal, and rectal swabs tested negative by rRT-PCR; one dog's fur swabs (2%) tested positive by rRT-PCR at the first sampling. Among 47 pets with serological results, eight (17%) pets (four dogs, four cats) from 6/30 (20%) households had detectable SARS-CoV-2 neutralizing antibodies. In households with a seropositive pet, the proportion of people with laboratory-confirmed COVID-19 was greater (median 79%; range: 40-100%) compared to households with no seropositive pet (median 37%; range: 13-100%) (p = 0.01). Thirty-three pets with serologic results had frequent daily contact (≥1 h) with the index patient before the person's COVID-19 diagnosis. Of these 33 pets, 14 (42%) had decreased contact with the index patient after diagnosis and none were seropositive; of the 19 (58%) pets with continued contact, four (21%) were seropositive. Seropositive pets likely acquired infection after contact with people with COVID-19. People with COVID-19 should restrict contact with pets and other animals.

Low SARS-CoV-2 Seroprevalence and No Active Infections among Dogs and Cats in Animal Shelters with Laboratory-Confirmed COVID-19 Human Cases among Employees.

Human-to-animal and animal-to-animal transmission of SARS-CoV-2 has been documented; however, investigations into SARS-CoV-2 transmission in congregate animal settings are lacking. We investigated four animal shelters in the United States that had identified animals with exposure to shelter employees with laboratory-confirmed COVID-19. Of the 96 cats and dogs with specimens collected, only one dog had detectable SARS-CoV-2 neutralizing antibodies; no animal specimens had detectable viral RNA. These data indicate a low probability of human-to-animal transmission events in cats and dogs in shelter settings with early implementation of infection prevention interventions.

A qualitative study of healthcare professionals' experiences of providing maternity care for Muslim women in the UK.

BACKGROUND: A growing Muslim population in the UK suggests the need for healthcare professionals (HCPs) to gain a better understanding of how the Islamic faith influences health related perceptions and healthcare seeking behaviour. Although some researchers have explored the experiences of Muslim women as recipients of healthcare, little attention has been paid to the challenges HCPs face as service providers on a day-to-day basis whilst caring for Muslim women. The aim of this study was to investigate HPCs lived experiences of providing maternity care for Muslim women. METHOD: Data was collected through twelve semi-structured one-to-one qualitative interviews with HCPs in a large National Health Service (NHS) maternity unit located in the North West of England. Interview participants included Community and specialist clinic (e.g. clinic for non-English speakers), Midwives in a variety of specialist roles (7), Gynaecology Nurses (2), Breastfeeding Support Workers (2) and a Sonographer (1). The audio-recorded interviews were transcribed and analysed thematically. RESULTS: The majority of participants expressed an understanding of some religious values and practices related to Muslim women, such as fasting the month of Ramadhan and that pregnant and breastfeeding women are exempt from this. However, HCPs articulated the challenges they faced when dealing with certain religious values and practices, and how they tried to respond to Muslim women's specific needs. Emerging themes included: 1) HCPs perceptions about Muslim women; 2) HCPs understanding and awareness of religious practices; 3) HCPs approaches in addressing and supporting Muslim women's religious needs; 4) Importance of training in providing culturally and religiously appropriate woman-centred care. CONCLUSION: Through this study we gained insight into the day-to-day experiences of HCPs providing care provision for Muslim women. HCPs showed an understanding of the importance of religious and cultural practices in addressing the needs of Muslim women as part of their role as maternity care providers. However, they also identified a need to develop training programmes that focus on cultural and religious practices and their impact on women's health care needs. This will help support HCPs in overcoming the challenges faced when dealing with needs of women from different backgrounds.

First Reported Cases of SARS-CoV-2 Infection in Companion Animals - New York, March-April 2020.

On April 22, CDC and the U.S. Department of Agriculture (USDA) reported cases of two domestic cats with confirmed infection with SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19). These are the first reported companion animals (including pets and service animals) with SARS-CoV-2 infection in the United States, and among the first findings of SARS-CoV-2 symptomatic companion animals reported worldwide. These feline cases originated from separate households and were epidemiologically linked to suspected or confirmed human COVID-19 cases in their respective households. Notification of presumptive positive animal test results triggered a One Health* investigation by state and federal partners, who determined that no further transmission events to other animals or persons had occurred. Both cats fully recovered. Although there is currently no evidence that animals play a substantial role in spreading COVID-19, CDC advises persons with suspected or confirmed COVID-19 to restrict contact with animals during their illness and to monitor any animals with confirmed SARS-CoV-2 infection and separate them from other persons and animals at home (1).

Exploring English speaking Muslim women's first-time maternity experiences: a qualitative longitudinal interview study.

BACKGROUND: Muslim women of child-bearing age make up a fair part of the UK society, however, literature addressing their health needs or experiences of health services have not been extensively researched. The term 'Muslim' is often combined with ethnic group identity, rather than used to refer to people distinguished by beliefs or affiliations. Muslim women commonly observe certain religious and cultural practices during their maternity journey. The little research there is in this area suggests that more could be done from a service provision perspective to support Muslim women through this significant life event. The aim of this study was to investigate Muslim women's perceived needs and the factors that influence their health seeking decisions when engaging with maternity services located in North-West of England. METHODS: The study used longitudinal semi-structured interviews with seven English-speaking first-time pregnant Muslim women receiving maternity care in North-West of England. Total of 21 interview; each woman was interviewed during the antenatal (29 to 40 weeks of pregnancy), immediate postnatal (within the first 2 months after birth) and later postnatal (4 months after birth) period. Audio-recorded interviews were transcribed and thematically analysed using Braun & Clark (2006) as a guide to forming a systematic approach to handling raw data. RESULTS: Muslim women associated most aspects of the maternity journey with their religious beliefs. Religion was not the primary reason for them becoming pregnant, yet it was an aspiration for them becoming mothers. Emerging themes include: 1) a spiritual perspective; 2) expression of religious requirements; 3) perceptions of healthcare professionals. Religious values and practices provided a positive resource for women during their maternity journey. They described how healthcare professionals approached their needs, while highlighting their concerns of the negative presentation of Muslims in Western media. CONCLUSION: Muslim women need to feel confident to express their needs within a maternity setting. Lack of awareness amongst healthcare professionals around religious values and how Muslim women may feel when expressing their needs can inhibit them getting optimal care that acknowledges their needs. The study concludes that educating healthcare professionals about Muslim women's worldview would enhance the quality of maternity care for Muslim women.

Estimating Risk to Responders Exposed to Avian Influenza A H5 and H7 Viruses in Poultry, United States, 2014-2017.

In the United States, outbreaks of avian influenza H5 and H7 virus infections in poultry have raised concern about the risk for infections in humans. We reviewed the data collected during 2014-2017 and found no human infections among 4,555 exposed responders who were wearing protection.

A qualitative study exploring midwives' perceptions and knowledge of maternal obesity: Reflecting on their experiences of providing healthy eating and weight management advice to pregnant women.

Midwives are responsible for providing advice regarding the complex issues of healthy eating and weight management during pregnancy. This study utilised an inductive data-driven thematic approach in order to determine midwives' perceptions, knowledge, and experiences of providing healthy eating and weight management advice to pregnant women. Semistructured interviews with 17 midwives were transcribed verbatim and data subjected to thematic analysis. The findings offer insight into the challenges facing midwives in their role trying to promote healthy eating and appropriate weight management to pregnant women. Three core themes were identified: (a) "If they eat healthily it will bring their weight down": Midwives Misunderstood; (b) "I don't think we are experienced enough": Midwives Lack Resources and Expertise; and (c) "BMI of 32 wouldn't bother me": Midwives Normalised Obesity. The midwives recognised the importance of providing healthy eating advice to pregnant women and the health risks associated with poor diet and obesity. However, they reported the normalisation of obesity in pregnant women and suggested that this, together with their high workload and lack of expertise, explained the reasons why systematic advice was not in standard antenatal care. In addition, the current lack of UK clinical guidance, and thus, possibly lack of clinical leadership are also preventing delivery of tailored advice. Implementation literature on understanding the barriers to optimal health care delivery and informing clinical practice through research evidence needs to be further investigated in this field. This study has recommendations for policy makers, commissioners, service providers, and midwives.

Two cases of hantavirus pulmonary syndrome in Randolph County, West Virginia: a coincidence of time and place?

Hantavirus pulmonary syndrome (HPS) is caused by an infection with viruses of the genus Hantavirus in the western hemisphere. Rodent hosts of hantaviruses are present throughout the United States. In July 2004, two HPS case-patients were identified in Randolph County, WV: a wildlife science graduate student working locally and a Randolph County resident. We interviewed family members and colleagues, reviewed medical records, and conducted environmental studies at likely exposure sites. Small mammals were trapped, and blood, urine, and tissue samples were submitted to the Centers for Disease Control and Prevention for laboratory analyses. These analyses confirmed that both patients were infected with Monongahela virus, a Sin Nombre hantavirus variant hosted by the Cloudland deer mouse, Peromyscus maniculatus nubiterrae. Other than one retrospectively diagnosed case in 1981, these are the first HPS cases reported in West Virginia. These cases emphasize the need to educate the public throughout the United States regarding risks and prevention measures for hantavirus infection.

Canine visceral leishmaniasis, United States and Canada, 2000-2003.

Visceral leishmaniasis, caused by protozoa of the genus Leishmania donovani complex, is a vectorborne zoonotic infection that infects humans, dogs, and other mammals. In 2000, this infection was implicated as causing high rates of illness and death among foxhounds in a kennel in New York. A serosurvey of >12,000 foxhounds and other canids and 185 persons in 35 states and 4 Canadian provinces was performed to determine geographic extent, prevalence, host range, and modes of transmission within foxhounds, other dogs, and wild canids and to assess possible infections in humans. Foxhounds infected with Leishmania spp. were found in 18 states and 2 Canadian provinces. No evidence of infection was found in humans. The infection in North America appears to be widespread in foxhounds and limited to dog-to-dog mechanisms of transmission; however, if the organism becomes adapted for vector transmission by indigenous phlebotomines, the probability of human exposure will be greatly increased.

Status of oral rabies vaccination in wild carnivores in the United States.

Persistence of multiple variants of rabies virus in wild Chiroptera and Carnivora presents a continuing challenge to medical, veterinary and wildlife management professionals. Oral rabies vaccination (ORV) targeting specific Carnivora species has emerged as an integral adjunct to conventional rabies control strategies to protect humans and domestic animals. ORV has been applied with progress toward eliminating rabies in red foxes (Vulpes vulpes) in western Europe and southern Ontario, Canada. More recently since 1995, coordinated ORV was implemented among eastern states in the U.S.A. to prevent spread of raccoon (Procyon lotor) rabies and to contain and eliminate variants of rabies virus in the gray fox (Urocyon cinereoargenteus) and coyote (Canis latrans) in Texas. In this paper, we describe the current cooperative ORV program in the U.S.A. and discuss the importance of coordination of surveillance and rabies control programs in Canada, Mexico and the U.S.A. Specifically, several priorities have been identified for these programs to succeed, which include additional oral vaccines, improved baits to reach target species, optimized ORV strategies, effective communication and legal strategies to limit translocation across ORV barriers, and access to sufficient long-term funding. These key priorities must be addressed to ensure that ORV has the optimal chance of achieving long range programmatic goals of eliminating specific variants of rabies virus in North American terrestrial carnivores.

The largest outbreak of measles in the United States during 1999: imported measles and pockets of susceptibility.

The largest measles outbreak in the United States during 1999 was traced to a 34-year-old minister with an undocumented history of vaccination, infected while traveling outside the United States. Local health departments in the Central Virginia Health District performed an epidemiological and laboratory investigation that identified 14 additional confirmed cases of measles, including 2 in health care providers and 5 in congregation members. Eight cases (53%) occurred among adults aged 30-35 years and 7 (47%) among children aged 13 months to 8 years. Although no religious exemptions were cited, only 2 case patients had documented proof of vaccination. This outbreak demonstrates the potential for limited indigenous spread of measles that occurs when imported cases expose susceptible groups. Almost half of the imported measles cases in the United States occur in US residents returning from foreign travel. Vaccination is highly recommended for all overseas travelers who are without documented proof of adequate immunization or measles immunity.
