Application of Healthcare Failure Mode and Effect Analysis in the Management of Patients With Intrathecal Morphine Pump Implantation.

Background: Intrathecal morphine pump helps alleviate pain in the advanced stages of cancer, and thus, ensuring safe intrathecal morphine pump infusion is important. In this study, we investigated the effect of healthcare failure mode and effects analysis (HFMEA) in the management of patients with intrathecal morphine pump implantation.

Methods: We included 112 cancer patients with severe pain who met the inclusion criteria for intrathecal morphine pump implantation treatment in the pain department of our hospital from November 2021 to October 2022.

Radical Isomerization Homopolymerization of Linear α-Olefins to Access C5, C6 or C7 Polymers.

Non-activated linear α-olefins are valuable building blocks for organic transformation or olefin (co)polymerization, but they are recognized as textbook knowledge for non-homopolymerizable monomers under radical conditions. In this article, we disclose our effort to achieve an unprecedented library of all carbon-bonded sequence-regulated polymers via radical isomerization homopolymerization of α-olefin derivatives. The success of this distinctive polymerization is attributed to the remarkable efficiency and selectivity exhibited during the cyano group migration or hydrogen atom transfer, which is greatly enhanced by the precise engineering of their monomer structures.

The Effects of WeChat-Based Teach-Back Health Education on Patients With Advanced Cancer Pain.

Background: Providing effective health education is essential for patients with cancer-related pain. One solution is leveraging instant messaging tools for teach-back health education.

Objectives: This study investigated the effects of WeChat-based teach-back health education on patients with advanced cancer who underwent patient-controlled intrathecal analgesia implantation and used hydromorphone.

Female behavioral strategies during consortship in Tibetan macaques ().

Consortship has been defined as a temporary association between an adult male and an estrous/receptive female. It has been considered as male mating strategies to improve male mating success and potential reproductive success. However, the female roles have been more or less neglected, and thus, less is known about female behavioral strategies during the consortship periods.

Social strategies used by dispersing males to integrate into a new group in Tibetan macaques (Macaca thibetana).

In group-living mammals, an individual's fitness depends, in part, on the quality of social relationships it has with others. Among species of nonhuman primates in which one sex is philopatric, individuals of that sex often develop strong social bonds and alliances with closely related kin. Less is known regarding the social processes used by dispersing adults to form stable bonds with nonkin in their new group.

Habitat characteristics or protected area size: What is more important for the composition and diversity of mammals in nonprotected areas?

The margins of protected areas are usually considered to have greater forest degradation, and given that most mammals live outside protected areas, researchers and conservation practitioners are increasingly recognizing that nonprotected areas must be incorporated into conservation strategy. However, the strategy used to manage these areas still involves increasing the size of protected areas, while not considering the habitat characteristics and requirements of the species. In this study, during a 3-year period, camera trap and habitat characteristic surveys were used to estimate composition, diversity, and habitat characteristics of mammals to determine habitat characteristics or increase the size of protected areas what should be considered first for mammals' conservation in a nonprotected area near the Huangshan Mountains in Anhui Province, China.

Sex-Specific Variation of Social Play in Wild Immature Tibetan Macaques, .

Theories proposed to explain social play have centered on its function in establishing social relationships critical for adulthood, its function in developing motor skills needed to survive, and promoting cognitive development and social learning. In this study, we compared variations in social play among infant and juvenile male and female . Given that this species is characterized by female philopatry and male dispersal, we hypothesized that immature females use social play as a mechanism to develop bonds that persist through adulthood whereas immature males use play to develop social skills needed to successfully enter new groups.

Sexual Interference Behaviors in Male Adult and Subadult Tibetan Macaques ().

Male nonhuman primate sexual interference, which includes copulation interruption and copulation harassment, has been related to reproductive success, but its significance has been challenging to test. Copulation interruption results in the termination of a copulation before ejaculation, whereas copulation harassment does not. We conducted this study using the all-occurrence behavior sampling method on sexual interference behaviors of seven adult and four subadult male Tibetan macaques () in mating and non-mating seasons at Mt.

Observation of the effect of a 7-day gradual early functional exercise program in middle-aged and young patients with acute myocardial infarction after percutaneous coronary intervention.

Background: Acute myocardial infarction (AMI) is characterized by a critical condition, rapid progression, and a high fatality rate. Percutaneous coronary intervention (PCI) is the treatment of choice for AMI. The purpose of this study was to investigate the efficacy of a 7-day gradual early functional exercise program after PCI in young and middle-aged patients with AMI.

Infant attraction: why social bridging matters for female leadership in Tibetan macaques.

Leadership is a key issue in the study of collective behavior in social animals. Affiliation-leadership models predict that dyadic partner preferences based on grooming relationships or alliance formation positively affect an individual's decision to follow or support a conspecific. In the case of many primate species, females without young infants are attracted to mother-infant dyads.

Grooming networks reveal intra- and intersexual social relationships in Macaca thibetana.

The analysis of grooming networks is a powerful tool to examine individual social and sexual relationships and how these relationships change over time. In this study, we investigated the seasonal dynamics of intra- and intersexual social relationships in Tibetan macaques (Macaca thibetana) based on grooming interactions. Similar to other female philopatric and male dispersal primates, female Tibetan macaques form the core of the social group with higher values of centralities, compared to the males who tend to be distributed on the periphery of the grooming network.

Social connectivity among female Tibetan macaques (Macaca thibetana) increases the speed of collective movements.

Social network analysis provides insights into patterns of group movements in primates, but fewer studies to date have focused on the dynamics of how such movements occur. In this study, we proposed and tested two hypotheses about the influence of sex on social connectivity and group movement in Tibetan macaques (Macaca thibetana): (1) adult females are socially more connected than are adult males and (2) social connectivity facilitates the speed of collective decision-making. We collected data from 128 successful collective movements (≥ 2 individuals followed an initiator within 5 min) over a 2-month period in a group of adult Tibetan macaques at Mt.

Playing it cool: Characterizing social play, bout termination, and candidate play signals of juvenile and infant Tibetan macaques (Macaca thibetana).

Play behaviors and signals during playful interactions with juvenile conspecifics are important for both the social and cognitive development of young animals. The social organization of a species can also influence juvenile social play. We examined the relationships among play behaviors, candidate play signals, and play bout termination in Tibetan macaques (Macaca thibetana) during juvenile and infant social play to characterize the species play style.

The prospect of rising in rank is key to long-term stability in Tibetan macaque society.

One of the most fundamental questions in behavioural biology is why societies can persist for a long period of time. While researchers in animal behaviour have been hindered by a lack of an aggregate measure (such as social mobility) to quantify the dynamics of animal societies, researchers in social sciences have been challenged by the complexity and diversity of human societies. As a result, direct empirical evidence is still lacking for the hypothesized causal relationship between social mobility and social stability.

Social rank versus affiliation: Which is more closely related to leadership of group movements in Tibetan macaques (Macaca thibetana)?

Research on leadership is a critical step for understanding collective decision making. However, only 4 of the 22 extant macaque species have been examined for the impact of social rank and affiliation on the initiation of collective movement. It is far from clear whether such impact exists and, if so, how it works among other macaques.

Collective Movement in the Tibetan Macaques (Macaca thibetana): Early Joiners Write the Rule of the Game.

Collective behavior has recently attracted a great deal of interest in both natural and social sciences. While the role of leadership has been closely scrutinized, the rules used by joiners in collective decision making have received far less attention. Two main hypotheses have been proposed concerning these rules: mimetism and quorum.

Park Rangers' Behaviors and Their Effects on Tourists and Tibetan Macaques (Macaca thibetana) at Mt. Huangshan, China.

Previous studies have reported the negative impacts of tourism on nonhuman primates (NHPs) and tourists and advocated the improvement of tourism management, yet what constitutes good quality management remains unclear. We explored whether rates of macaque aggression and self-directed behaviors (SDBs) differed under the supervision of two park ranger teams at the Valley of the Wild Monkeys (VWM) in Mt. Huangshan, Anhui Province, China.

Grooming reciprocity in female tibetan macaques macaca thibetana.

Grooming among nonhuman primates is widespread and may represent an important service commodity that is exchanged within a biological marketplace. In this study, using focal animal sampling methods, we recorded grooming relationships among 12 adult females in a free-ranging group of Tibetan macaques (Macaca thibetana) at Huangshan, China, to determine the influence of rank and kinship on grooming relationships, and whether females act as reciprocal traders (exchange grooming received for grooming given) or interchange traders (interchange grooming for social tolerance or other commodities). The results showed that: (1) grooming given was positively correlated with grooming received; (2) kinship did not exert a significant influence on grooming reciprocity; and (3) grooming reciprocity occurred principally between individuals of adjacent rank; however, when females of different rank groomed, females tended to groom up the hierarchy (lower ranking individuals groomed higher ranking individuals more than vice versa).

First occurrence of twins in provisioned free-ranging Tibetan macaques (Macaca thibetana) at Huangshan, China.

A first case of newborn Tibetan macaque (Macaca thibetana) twins was observed in a free-ranging group at Huangshan, China. The female that gave birth to the twins was studied during their first 5 months post-partum, and her activity budget was compared to those of adult females with single or no offspring in order to assess her behavioral changes. Our report shows that female Tibetan macaques can produce twins, and that twins can successfully survive.

Foxn1 gene knockout suppresses sexual attractiveness and pheromonal components of male urine in inbred mice.

The immunocompetence handicap hypothesis (ICHH) posits that females prefer signals emitted by immunocompetent males over immunocompromised males and that these signals are honest. However, mechanisms of mate choice under an ICHH model may be impacted by levels of genetic variation (inbred animals vs. outbred animals).

Dual role of preputial gland secretion and its major components in sex recognition of mice.

This study was aimed at validating the sexual attractiveness of hexadecanol and hexadecyl acetate, two putative pheromone compounds, from preputial gland secretion of mice. These two compounds have been reported to be among the major components of preputial gland secretion in both sexes but higher in quantity in males than females. In this study, we show that castration suppressed the production of the two compounds, further suggesting their association with maleness.

Sex- and gonad-affecting scent compounds and 3 male pheromones in the rat.

This study was aimed at identifying sex pheromones of the rat (Rattus norvegicus). We characterized the volatiles and semivolatiles of rat preputial gland and voided urine by using gas chromatography-mass spectrometry (GC-MS) and quantified them by their GC areas (abundances) and percentage of GC areas (relative abundances). Although all the compounds other than 4-heptanone and phenol detected were shared by males and females, the quantities for some of these sex-common compounds exhibited sexual dimorphism and decreased with gonadectomy.

Cohabitation impaired physiology, fitness and sex-related chemosignals in golden hamsters.

This study investigated the impact of long-term paternal presence (cohabitation) on several physiological parameters such as body weight, adrenal weight, cortisol of parents, and the survival of pups compared with brief daily encounters (isolation) of male-female pairs in golden hamsters (Mesocricetus auratus). We showed that females were affected more by cohabitation as evidenced by increased body and adrenal weights, elevated cortisol concentrations, and heavier uteri and spleens as compared with cohabiting male and isolated females. Furthermore, we found that tetradecanoic and hexadecanoic acids of the flank glands were sexually dimorphic, for which they were putative female pheromones.

Potential chemosignals in the anogenital gland secretion of giant pandas, Ailuropoda melanoleuca, associated with sex and individual identity.

With a combination of dichloromethane extraction and analysis by gas chromatography-mass spectrometry (GC-MS), we found 39 compounds (corresponding to 38 GC peaks) in the anogenital gland secretion (AGS) of captive adult giant pandas, Ailuropoda melanoleuca, during the non-mating season. In addition to indole, squalene, and some of the straight-chain fatty acids that had been characterized previously from the AGS of giant pandas, we identified several new compounds such as decenal, two isomers of decadienal, phenylacetic acid, 5-methylhydantoin, hydroquinone, phenylpropanoic acid, and erucic acid. Quantitative comparison of the relative abundances of the 20 main GC peaks revealed that 5-methylhydantoin, indole, and erucic acid are putative female pheromones, whereas squalene and hydroquinone are putative male pheromones.
