A new method has been introduced to predict impact sensitivity of different types of polynitroheteroarenes which can include nitropyridine, nitroimidazole, nitropyrazole, nitrofurazane, nitrooxadiazole, nitro-1,2,4-triazole, nitro-1,2,3-trazole and nitropyrimidine explosives. The model is based on the number of carbons and hydrogens as well as specific structural parameters that can increase or decrease impact sensitivity. The new method has been applied to 67 polynitroheteroarenes which have different structural parameters. The predicted results are compared with outputs of recent calculated results of complex neural network. The root mean squares (rms) of deviations of different polynitroheteroarenes are 36 and 66 cm for the new and neural network methods, respectively. The novel model also predicts good results for some miscellaneous nitroheterocyclic explosives and several new synthesized polynitroheteroarenes compared to experimental data.

Purpose: Informal caregivers of people with high grade glioma (HGG) often have high levels of unmet support needs. Routine screening for unmet needs can facilitate appropriate and timely access to supportive care. We aimed to develop a brief screening tool for HGG caregiver unmet needs, based on the Supportive Care Needs Survey-Partners & Caregivers (SCNS-P&C).

Intermittent hypoxemia (IH), a pathophysiologic consequence of obstructive sleep apnea (OSA), adversely affects insulin sensitivity, insulin secretion, and glucose tolerance. Nifedipine, an L-type calcium channel blocker frequently used for treatment of hypertension, can also impair insulin sensitivity and secretion. However, the cumulative and interactive repercussions of IH and nifedipine on glucose homeostasis have not been previously investigated.

Cisplatin, a chemotherapeutic drug, is known for causing gastrointestinal disorders and neuropathic pain, but its impact on visceral sensitivity is unclear. Monosodium glutamate (MSG) has been shown to improve gastrointestinal dysmotility and neuropathic pain induced by cisplatin in rats. This study aimed to determine if repeated cisplatin treatment alters visceral sensitivity and whether dietary MSG can prevent these changes.

: Internet use positively impacts mental health in older adults, with health literacy (HL) playing a key role. While social networks may complement individual HL, the role of neighborhood relationships in this association, particularly by gender, remains unclear. This study examined how the association between HL and Internet use among older adults was modified by neighborhood relationships.

Aim(s): To clarify the concept of preconception care and develop a precise and inclusive definition to improve its implementation and impact on reproductive health outcomes.
Design: This concept analysis paper employs Rodgers' evolutionary method to analyse the concept of preconception care, examining its historical evolution, attributes, antecedents and consequences.
Methods: A comprehensive literature review was conducted using databases such as Cumulative Index to Nursing and Allied Health Literature, Scopus, MEDLINE and Google Scholar, covering publications from 2012 to 2024.
