68 days) of LO were significantly shorter than those of TIO group (P  less then  .05). Forty-seven of 49 cases (95.9%) aged less then 1 year successfully achieved LO. Conclusion LO is an appropriate choice for palpable UDT, especially in younger children aged less then 2 years. The success rate of LO decreased with age.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of manmade chemicals containing at least one fully fluorinated carbon atom. The widespread use, large number, and diverse chemical structures of PFAS pose challenges to any sufficiently protective regulation, emissions reduction, and remediation at contaminated sites. learn more Regulating only a subset of PFAS has led to their replacement with other members of the class with similar hazards, that is, regrettable substitutions. Regulations that focus solely on perfluoroalkyl acids (PFAAs) are ineffective, given that nearly all other PFAS can generate PFAAs in the environment.

In this commentary, we present the rationale adopted by the State of California's Department of Toxic Substances Control (DTSC) for regulating PFAS as a class in certain consumer products.

We at the California DTSC propose regulating certain consumer products if they contain any member of the class of PFAS because

) all PFAS, or their degradation, reaction, or metabolism produstence; and b) certain key PFAS that are the degradation, reaction or metabolism products, or impurities of nearly all other PFAS display additional hazard traits, including toxicity; are widespread in the environment, humans, and biota; and will continue to cause adverse impacts for as long as any PFAS continue to be used. Regulating PFAS as a class is thus logical, necessary, and forward-thinking. This technical position may be helpful to other regulatory agencies in comprehensively addressing this large class of chemicals with common hazard traits. https//doi.org/10.1289/EHP7431.

To benchmark the radiation dose to patients during the course of treatment for a spinal deformity.

Our radiation dose database identified 25,745 exposures of 6,017 children (under 18 years of age) and adults treated for a spinal deformity between 1 January 2008 and 31 December 2016. Patients were divided into surgical (974 patients) and non-surgical (5,043 patients) cohorts. We documented the number and doses of ionizing radiation imaging events (radiographs, CT scans, or intraoperative fluoroscopy) for each patient. All the doses for plain radiographs, CT scans, and intraoperative fluoroscopy were combined into a single effective dose by a medical physicist (milliSivert (mSv)).

There were more ionizing radiation-based imaging events and higher radiation dose exposures in the surgical group than in the non-surgical group (p < 0.001). The difference in effective dose for children between the surgical and non-surgical groups was statistically significant, the surgical group being significantly higher (p < 0.001). This led to a higher estimated risk of cancer induction for the surgical group (1222 surgical vs 11,418 non-surgical). However, the dose difference for adults was not statistically different between the surgical and non-surgical groups. In all cases the effective dose received by all cohorts was significantly higher than that from exposure to natural background radiation.

The treatment of spinal deformity is radiation-heavy. The dose exposure is several times higher when surgical treatment is undertaken. Clinicians should be aware of this and review their practices in order to reduce the radiation dose where possible. Cite this article

Despite increasing numbers of men living in isolation with dementia in the community, uptake of supportive interventions remains low. This may be because of limited availability of activities suited to men's interests. One organisation reporting higher attendance from men is Sporting Memories, offering inclusive sports-based reminiscence and physical activities for men living with dementia. This study aimed to explore the impact of the Sporting Memories intervention on men living with dementia.

This study was an ethnography employing techniques of participant observation, informal conversations and semi-structured interviews with group participants. Data were woven into a series of narratives using creative non-fiction, to bring life to the first-hand accounts of participants and experiences within a typical group setting.

The groups provided an environment for men with dementia to explore, reflect upon and reinforce their masculine identities through the subject of sport. Physical activities further facilitated this embodied demonstration for some, although this was not a feature of all sessions.

The content of Sporting Memories group sessions provides a vehicle for men to retain an important aspect of personhood. They also hold the potential to present opportunities for men to feel a sense of value by contributing to sessions in varied ways. Facilitators and volunteers require support and training to ensure this benefit is maintained.

A fistula is typically defined as a pathological communication between two epithelialized surfaces. More specifically, perianal fistula manifests as an abnormal tract between the anorectal canal and the perianal skin. Perianal fistulas are often characterized by significantly decreased patient quality of life. The cryptoglandular theory of perianal fistulas suggests their development from the proctodeal glands, which originate from the intersphincteric plane and perforate the internal sphincter with their ducts. Involvement of proctodeal glands in the inflammatory process could play a primary role in the formation of cryptoglandular perianal fistula. The objective of this narrative review was to investigate the current knowledge of the pathogenesis of cryptoglandular perianal fistula with the specific aims of characterizing the potential role of proinflammatory factors responsible for the development of chronic inflammation.
