Abstract When the nasal and oral passages converge and a bolus enters the pharynx, it is critical that breathing and swallow motor patterns become integrated to allow safe passage of the bolus through the pharynx. Breathing patterns must be reconfigured to inhibit inspiration, and upper airway muscle activity must be recruited and reconfigured to close the glottis and laryngeal vestibule, invert the epiglottis, and ultimately protect the lower airways. Failure to close and protect the glottal opening to the lower airways, or loss of the integration and coordination of swallow and breathing, increases the risk of penetration or aspiration. A neural swallow central pattern generator (CPG) controls the pharyngeal swallow phase and is located in the medulla. We propose that this swallow CPG is functionally organized in a holarchical behavioral control assembly (BCA) and is recruited with pharyngeal swallow. The swallow BCA holon reconfigures the respiratory CPG to produce the stereotypical swallow breathing pattern, consisting of swallow apnea during swallowing followed by prolongation of expiration following swallow. The timing of swallow apnea and the duration of expiration is a function of the presence of the bolus in the pharynx, size of the bolus, bolus consistency, breath cycle, ventilatory state and disease.

Cancer is increasing worldwide. Th e Russian Federation is no exception in this regard with an increase of the total number of new cases predicted to rise from 529,062 in 2018 to 587,622 in 2040. Th e present high burden and increase in incident cases at the same time increases the pressure on healthcare infrastructure and related costs. Th us, primary and secondary prevention of cancer becomes essential. Occupational cancers related to exposure at the workplace are among the preventable cancer burden, due to the modifi ability of the risk through minimisation of occupational exposures and adequate worker protection. For the Russian Federation, some 20,000 cancers each year may be att ributable to occupation, but systematic recording is currently lacking. As information is also lacking on the absolute eff ect of various occupational carcinogens in the Russian workforce due to lack of large-scale epidemiological studies and because for many suspected occupational carcinogens the evidence may become stronger, the true burden may in fact be higher. Th e Russian Federation appears particularly suitable for research into occupational cancer given the sizable workforce, the heavy industr ialisation as well as the good documentation and workplace surveillance over time, so that results are both informative for the situation in the Russian Federation and on a global scale. Five challenging but not unfeasible steps of nationwide population-based cancer registration, development of a legal framework for record linkage of registries and data collections, recording of occupational cancers, large scale epidemiological occupational cancer research and rigorous implementation of worker protection on known carcinogens, lead the way to a continuously updated cancer control plan that includes the elimination of occupational cancer in the Russian Federation.
