AbstractObjectiveThe aim of this work was to evaluate the relationship of the maternal mortality ratio due to obstetric haemorrhage (MMROH) with the national blood donations, particularly O RhD negative (Oneg) before and during COVID‐19 pandemic.BackgroundThe maternal mortality ratio is increasing in Colombia, yet little is known regarding the relationship between blood donations and maternal mortality due to obstetric haemorrhage.Materials and MethodsA retrospective cross‐sectional study between January 1, 2018, and December 31, 2021, was performed, to assess MMROH compared to the blood donations notified to the Colombian National Haemovigilance System, through non‐parametric methods. Because a relationship between blood donations and MMROH was identified, the analysis was expanded from 2009 to 2017.ResultsIn 2020, Colombia increased the MMROH by 32% compared to 2019 which coincided with the lockdown period to contain COVID‐19. An inversed relationship (SumD2 = 631.0; rs = −0.7335; p 0.01) between blood donations, particularly Oneg (SumD2 = 652.0; rs = −0.7912; p 0.002) and MMROH was identified. For the years 2015–2019 and 2021, the annual mean MMROH was 8.5 ± 0.5 per 100 000 live births when the annual mean blood donations was 18.2 ± 0.4 donations per 1000 people and the Oneg was 1.0 ± 0.0 donations per 1000 people. In contrast, the years 2009–2014 and 2020 displayed an annual MMROH of 12.6 ± 0.8, when the annual collection of blood was 16.4 ± 0.8 donations and the Oneg was 0.9 ± 0.0, p < 0.001.ConclusionThere was an inverse relationship between blood donation, mainly Oneg, and maternal mortality from obstetric haemorrhage. However, we recognise these deaths could be related to other reasons, especially when they occurred in rural areas with limited access to medical services.

Abstract
This study investigates fatigue life and fracture in welded stainless steel 304L (SS 304L) resulting from load-controlled fatigue. This was done for specimens from two welding manufacturers. Mechanical testing was carried out using an MTS test frame in uniaxial tension. Specimens fabricated in three weld configurations (butt, lap, and butt-with-backer) were cycled at stress ratio R = 0.1, frequency f = 5 Hz, and experienced varying mean tensile stress. A comparison of the fatigue life of welded and unwelded (or pristine) specimens determined that the fatigue life of welded specimens is considerably shorter. The microstructure in the parent material (PM), heat-affected (HAZ), and fusion zones (FZ) was analyzed using SEM, and results suggest that, for a limited number of specimens (backer welds), fracture in the (FZ) was primarily the result of Zener–Stroh cracks. Most welded specimens fractured at the weld-HAZ interface (weld toe), and we postulate that stress concentrations primarily due to abrupt geometrical change at the weld interface led to crack initiation there. Additional stress concentrations at welding-induced defects (resulting from high temperature) such as second-phase particles, fatigue-induced defects, and preexisting impurities are responsible for crack initiation, crack growth, and eventual fracture. Comparison of unwelded and welded SN curve data using numerical curve-fitting methods reveals that the fatigue life of pristine SS 304L follows the expected sigmoid shape found in literature (specifically the Chandran fatigue model), while that of welded SS 304L deviates considerably in low cycle fatigue (LCF) and follows the Basquin power law equation.
Enhancement of Contact Acoustic Nonlinearity Effect in a Concrete Beam Using Ambient Vibrations
Authors: Wang Yikuan , Mukherjee Abhijit 
Published: December 2023

Abstract
Contact acoustic nonlinearity (CAN) is generated when oscillating crack faces open and close while a wave passes through it. However, reliably assessing the nonlinear effect due to micro-scale defects is challenging, especially in concrete structures, due to their large size, high attenuation, and low signal-to-noise ratio. However, concrete facilities vibrate due to ambient excitations such as vehicle movement, wind, and water flow. These ambient vibrations can be utilized in amplifying CAN. For example, a vehicle can be moved at a particular velocity over a bridge to amplify a particular natural mode of vibration. This paper illustrates a method of enhancing contact acoustic nonlinearity with the help of ambient vibrations of the structure. A finite element model of a concrete beam with a thin crack is developed. The base of the beam was oscillated at 100 Hz. Meanwhile, a 200 kHz ultrasonic excitation was applied on the beam to monitor its propagation through the crack. The closing and opening of the crack generate the nonlinear behavior of the ultrasonic pulse. A considerable increment of nonlinearity was observed demonstrating the efficacy of the proposed method. The time windows for the nonlinear zone have been identified. A laboratory experiment has been performed to demonstrate the proposed method in reinforced concrete beams. This investigation demonstrates that CAN can be utilized in monitoring concrete structures when ambient vibrations are taken into account.

Purpose: To assess associations between sedentary time (ST), physical activity (PA), and cardiovascular health in early childhood. Method: Cross-sectional study including 160 children (age 6.1 y [SD 0.5], 86 boys, 93 maternal body mass index ≥ 30 kg/m2, and 73 gestational diabetes) assessed for pulse wave velocity, echocardiography, ultra-high frequency 48–70 MHz vascular ultrasound, and accelerometery. Results: Boys had 385 (SD 53) minutes per day ST, 305 (SD 44) minutes per day light PA, and 81 (SD 22) minutes per day moderate to vigorous PA (MVPA). Girls had 415 (SD 50) minutes per day ST, 283 (SD 40) minutes per day light PA, and 66 (SD 19) minutes per day MVPA. In adjusted analyses, MVPA was inversely associated with resting heart rate (β = −6.6; 95% confidence interval, −12.5 to −0.7) and positively associated with left ventricular mass (β = 6.8; 1.4–12.3), radial intima-media thickness (β = 11.4; 5.4–17.5), brachial intima-media thickness (β = 8.0; 2.0–14.0), and femoral intima-media thickness (β = 1.3; 0.2–2.3). MVPA was inversely associated with body fat percentage (β = −3.4; −6.6 to −0.2), diastolic blood pressure (β = −0.05; −0.8 to −0.1), and femoral (β = −18.1; −32.4 to −0.8) and radial (β = −13.4; −24.0 to −2.9) circumferential wall stress in boys only. ST and pulse wave velocity showed no significant associations. Conclusions: In young at-risk children, MVPA is associated with cardiovascular remodeling, partly in a sex-dependant way, likely representing physiological adaptation, but ST shows no association with cardiovascular health in early childhood.

Published: December 2023

BACKGROUND:
Lower-limb amputation rates in patients with chronic limb-threatening ischemia vary across the United States, with marked disparities in amputation rates by gender, race, and income status. We evaluated the association of patient, hospital, and geographic characteristics with the intensity of vascular care received the year before a major lower-limb amputation and how intensity of care associates with outcomes after amputation.

METHODS:
Using Medicare claims data (2016–2019), beneficiaries diagnosed with chronic limb-threatening ischemia who underwent a major lower-limb amputation were identified. We examined patient, hospital, and geographic characteristics associated with the intensity of vascular care received the year before amputation. Secondary objectives evaluated all-cause mortality and adverse events following amputation.

RESULTS:

Of 33 036 total Medicare beneficiaries undergoing major amputation, 7885 (23.9%) were due to chronic limb-threatening ischemia; of these, 4988 (63.3%) received low-intensity and 2897 (36.7%) received high-intensity vascular care. Mean age, 76.6 years; women, 38.9%; Black adults, 24.5%; and of low income, 35.2%. After multivariable adjustment, those of low income (odds ratio, 0.65 [95% CI, 0.58–0.72];
P
<0.001), and to a lesser extent, men (odds ratio, 0.89 [95% CI, 0.81–0.98];
P
=0.019), and those who received care at a safety-net hospital (odds ratio, 0.87 [95% CI, 0.78–0.97];
P
=0.012) were most likely to receive low intensity of care before amputation. High-intensity care was associated with a lower risk of all-cause mortality 2 years following amputation (hazard ratio, 0.79 [95% CI, 0.74–0.85];
P
<0.001).

CONCLUSIONS:
Patients who were of low-income status, and to a lesser extent, men, or those cared for at safety-net hospitals were most likely to receive low-intensity vascular care. Low-intensity care was associated with worse long-term event-free survival. These data emphasize the continued disparities that exist in contemporary vascular practice.

The purpose of this research is to examine the reasons and goals of cricket sport. The research universe consisted of the athletes participating in the Cricket Türkiye Championship. The research data were created with the “Reasons for Starting Sports and Expectations Scale”. A total of 136 cricket players (54 female 82 male) participated in the study. Frequency, t-Test and ANOVA were used in the analysis of the data. In the research, the desire to become a world-famous athlete and a national team athlete stand out among the reasons for turning to cricket. Among the reasons for engaging in cricket sports were the feeling of gaining the most success and loving this sport. When we look at the expectations from cricket, it is seen that although the expectations of being a national team athlete and a well-known athlete are high, the expectation of living a financially comfortable life is the least preferred situation. Gender, being a national athlete, educational status were found to have effects on cricketing, engagement and future expectations (p<0.05)
As a result of it has been reported that the desire to be a national athlete in cricket is the most important factor in the orientation and expectations of this sport.

How the Future Shapes Consumption with Time-Inconsistent Preferences
Authors: Feigenbaum James , Raei Sepideh 
Published: December 2023

Abstract
Time-inconsistent preferences, which are modeled by relative discount functions, are a common explanation for the empirical finding that lifecycle profiles of household consumption are typically hump-shaped rather than monotonic. More precisely, time-inconsistent preferences that are present-biased often generate a hump-shaped consumption profile over the lifecycle. We develop a general framework for understanding present bias in consumption through a future weighting factor that perturbs the discount factor of utility at future periods away from exponential discounting. Using our framework we derive necessary and sufficient conditions on the future weighting factors for the log consumption profile to be locally concave. We find that these conditions, which are necessary for the consumption profile to be hump-shaped, are stronger than just assuming a present bias. Furthermore, we explore the conditions under which the consumption profile determined in the first period of life Pareto dominates the realized consumption profile. Lastly, we explore the interconnections between these two sets of conditions, elucidating the linkages between the determinants of hump-shaped consumption profiles and the conditions necessary for the initial consumption path to achieve Pareto dominance.
“And the House Burned Down”: HIV, Intimacy, and Memory in Danez Smith’s Poetry
Authors: Juncosa Toni R. 
Published: December 2023

Abstract
Danez Smith’s [insert] boy (2014) not only bears witness to the intricacy of the intersection between queerness and Blackness in the United States of the twenty-first century, but also illustrates an overcoming of multiple forms of oppression through poetry. In Smith’s second collection Don’t Call Us Dead (2017), this experience is further complicated when a positive HIV diagnosis enters the equation. This paper wonders about the possibility of reading the speaker's account of HIV as following a narrative arc from anxiety to agency. With this idea in mind, and probing into issues such as intimacy, kinship, memory, and the notion of home, this paper presents a comparative analysis of Danez Smith’s poetry focusing on the metaphors used to explore the penetration of HIV into the body and the alterations this experience imposes on the perception of intimacy and memory.

Abstract

Objectives
Seasonal environment at birth may influence diabetes incidence in later life. We sought evidence for this effect and analyzed the association between the month of birth and the risk of developing type 1 diabetes mellitus (T1DM).

Methods
This was a cohort study carried out with 814 patients diagnosed with T1DM in the region of Bauru – São Paulo State, Brazil, receiving medical care in a private Endocrinology clinic or in the public Brazilian National Health Care System, from 1981 to 2021. All live births that occurred in São Paulo State between 1974 and 2020 were classified by month of birth and were considered as the control group.

Results
We found no statistically significant difference (χ2=16.31, critical 19.68) between the month of birth and risk of developing T1DM, when comparing our patients with the background population of the region. There was no association between the month of birth, sex, age at diagnosis, duration of symptoms before diagnosis, self-reported color, and socioeconomic status.

Conclusions
We found no association between month of birth and the risk of developing T1DM in this highly admixed South American population. Our data suggest that our population heterogeneity and geographic location may be important factors in the development of T1DM. Future prospective studies, evaluating environmental factors that may confer risk or protection to the disease, are warranted.

Abstract
Ibn Tofail University of Kenitra, Morocco, is committed to a national policy of control and mobilization of water resources and the adoption of a planning approach and integrated water management. Within this framework, the university, which contains 40,000 students, produces a quantity of wastewater of 200 m3 per day. After treatment, the water is used for watering the university’s green space. The treatment process chosen is a membrane bioreactor (MBR), which is considered to be energy intensive. Therefore, the production of energy for the station will be made by renewable energy wind and photovoltaic (PV). The dimensioning of the MBR was made by a research department, which estimated that the energy necessary for the station is 1061.76 kW h/day. The aim of this work is to dimension and optimize the platform for the production of energy, using the Matlab program for the wind turbine and the PVsyst program for PV. The results of coupling our plant with an on-grid PV system and wind turbine show that it was able to reach an electrical coverage of about 72% of the wastewater treatment (WWT) plant’s energy needs. Thus, an estimated reduction of electricity of 0.53 euro on each m3 of water produced by the WWT plant and thus 106.76 euro on the 200 m3 produced daily by the station.

Published: December 2023

Marijuana (cannabis) as a therapeutic medication has been used and recognized as part of the health system in several countries. In contrast, marijuana in Indonesia is classified as a class I narcotic under Law Number 35 of 2009 on Narcotics, which is prohibited and cannot be used as medication. However, a detailed examination of the Narcotics Act reveals some loopholes and ambiguities that could be exploited to legalize marijuana as a medication to cure certain illnesses. The present study employs normative legal research, specifically a statutory approach, to justify using marijuana for medical purposes. In addition, a legal comparative method is also used in this study to analyze the use of medical marijuana in three ASEAN countries: Thailand, Malaysia, and Singapore. Despite having a reputation for having highly stringent regulations on narcotics, Indonesia can benefit from the experiences of other ASEAN nations, such as Singapore and Malaysia, who have legalized medical marijuana. This consideration is prompted by the fact that certain individuals have shared positive outcomes from using ‘illegal’ medical marijuana as a form of health treatment. However, it is disheartening to note that these individuals have also had to witness the unfortunate loss of their loved ones and, in some cases, face legal consequences such as imprisonment. Conducting comprehensive research on the use of medicinal marijuana in Indonesia is crucial to upholding the citizens' right to health, as the right to health is a significant component of human rights.
