The World Health Organization (WHO) commissioned 12 systematic reviews (SR) and meta-analyses (MA) on health effects of exposure to radiofrequency electromagnetic fields (RF-EMF). The health outcomes selected for those reviews (cancer, electromagnetic hypersensitivity, cognitive impairment, birth outcomes, male fertility, oxidative stress, and heat-related effects) were based on a WHO-conducted international survey. The SR of the studies of cancer in laboratory animal studies was the only one that did not include a MA, because those authors considered it inappropriate due to methodological differences among the available studies, including differences in exposure characteristics (carrier frequency, modulation, polarization), experimental parameters (hours/day of exposure, duration of exposure, exposure systems), and different biological models. MAs in all the other SRs suffered from relatively few primary studies available for each MA (sometimes due to excessive subgrouping), exclusion of relevant studies, weaknesses in many of the included primary studies, lack of a framework for analyzing complex processes such as those involved in cognitive functions, and/or high between-study heterogeneity. Due to serious methodological flaws and weaknesses in the conduct of the reviews and MAs on health effects of RF-EMF exposure, the WHO-commissioned SRs cannot be used as proof of safety of cell phones and other wireless communication devices. However, the animal cancer SR, which was rated as “high certainty of evidence” for heart schwannomas and “moderate certainty of evidence” for brain gliomas, provided quantitative information that could be used to set exposure limits based on reducing cancer risk. The multiple and significant dose-related adverse effects found in the SRs on male fertility and pregnancy and birth outcome should also serve as the basis for policy decisions to lower exposure limits and reduce human reproductive risks. The report of harmful effects (e.g., cancer, reproductive toxicity, etc.) at doses below the adverse health effect threshold claimed by ICNIRP demonstrates that current exposure limits to RF-EMF, which were established by applying arbitrary uncertainty factors to their putative adverse threshold dose, lack scientific credibility.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12940-025-01220-4.

The topic of euthanasia/assisted suicide in the United States is emotionally charged. due to grassroots efforts, patient-initiated lawsuits, and attempts to punish those participating in physician-assisted suicide, the issue has been brought into the public eye and will not disappear. Nurses are challenged to consider this debate objectively in order to support public policy that leads to sensitive and appropriate patient care. This policy analysis examines how the issues of assisted suicide and euthanasia are being dealt with both nationally and internationally, and considers various policy options.

Summary After removal of 1 metatarsal pad and formation of a granulation tissue bed, free segmental 6- × 8-mm grafts from digital pads were sutured into recessed same-size recipient sites in the granulation tissue. In 5 dogs, the grafted area had been denervated by excision of a segment of the tibial nerve at the level of the tarsus. The grafted area was not denervated in the remaining 5 dogs. In both groups of dogs, the grafts placed around the periphery of the wound healed, blocked ingrowth of delicate epithelium from the surrounding skin, and provided a tough keratinized epithelium that covered the wound's center. As healing progressed, the grafts coalesced as the wounds contracted. Weight bearing resulted in graft expansion to provide functional weight-bearing tissue. Dogs of the denervated group had clinical and histologic evidence of collateral sensory reinnervation of the denervated area. However, with the exception of 1 dog, results of sensory nerve action potential tests indicated that reinnervation may not have been by way of regeneration across the excisional gap in the nerve. Evaluation of reinnervation of the tibial autonomous zone in 2 additional dogs revealed clinical evidence that collateral reinnervation began between 19 and 28 days after nerve excision and progressed proximad to distad. Results of sensory nerve action potential tests indicated that reinnervation may not have been via regeneration across the excision site. Results of fluorescent tracer studies did not have positive findings regarding the route of collateral reinnervation. Segmental paw pad grafts can be used effectively to provide weight-bearing tissue on a dog's limb. With local nerve damage on the distal portion of the limb, collateral innervation can grow into the area to reinnervate tissues, including pad grafts.

Abstract Age regression during hypnosis and mental rehearsal while in trance, using a cassette tape for induction, enabled a patient, with disruption of flexor function of the fifth finger of her right hand, to restore full function, even though she did not have a strong belief system in hypnosis.

This essay is a retrospective look at the proceedings in the context of the large-scale questions which prompted the whole venture.

A direct use is made of the straight-line preliminary plot which obtains when the two-line emulsion calibration method is used with coordinates in terms of Seidel values, yielding an expression for the log of intensity ratio in terms of differences of densitometer readings, expressed as Seidel values, from a constant obtained from the preliminary plot. The equation may be used in a computer program or may be handled on special electronic desk calculators which provide for logarithmic manipulations. By substituting an arbitrary constant for one Seidel value, a table of relative intensities can be prepared for a list of transmittance readings.
